SUBJECT TO COMPLETION, DATED JULY 23, 2025

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

Dear Stockholders of DNOW Inc. and MRC Global Inc.:

On behalf of the boards of directors of DNOW Inc., a Delaware corporation (“DNOW”), and MRC Global Inc., a Delaware corporation (“MRC Global”), we are pleased to enclose the accompanying joint proxy statement/prospectus relating to the merger between DNOW and MRC Global. We are requesting that you take certain actions as a DNOW or MRC Global stockholder.

On June 26, 2025, DNOW entered into an agreement and plan of merger (the “merger agreement”) with MRC Global, Buck Merger Sub, Inc., a Delaware corporation and a wholly-owned, direct subsidiary of DNOW (“Merger Sub”), and Stag Merger Sub, LLC, a Delaware limited liability company and a wholly-owned, direct subsidiary of DNOW (“LLC Sub”). The merger agreement provides that, among other things and subject to the terms and conditions of the merger agreement, (1) Merger Sub will be merged with and into MRC Global (the “First Merger”), with MRC Global continuing as the surviving corporation in the First Merger (the time the First Merger becomes effective, the “Effective Time”) and (2) immediately following the First Merger, MRC Global will be merged with and into LLC Sub (the “Second Merger” and, together with the First Merger, the “mergers”), with LLC Sub continuing as the surviving company at the effective time of the Second Merger as a wholly-owned, direct subsidiary of DNOW.

If the mergers are completed, subject to certain exceptions, (i) each share of common stock, $0.01 par value, of MRC Global (the “MRC Global common stock”) held immediately prior to the Effective Time by DNOW or any of DNOW’s subsidiaries, or by MRC Global or any of MRC Global’s subsidiaries (collectively, the “Excluded Shares”), shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor, and (ii) each share of MRC Global common stock issued and outstanding (other than Excluded Shares) immediately prior to the Effective Time shall be converted into the right to receive 0.9489 shares (the “exchange ratio”) of common stock, $0.01 par value, of DNOW (the “DNOW common stock”), with cash paid in lieu of the issuance of fractional shares, if any.

Following the completion of the mergers, it is anticipated that persons who were stockholders of DNOW and MRC Global immediately prior to the mergers will own approximately 56.5% and 43.5% of the combined company, respectively, on a fully diluted basis.

Completion of the mergers requires, among other things, the separate approvals of both the holders of DNOW common stock (the “DNOW stockholders”) and the holders of shares of MRC Global common stock (the “MRC Global stockholders”). To obtain the required stockholder approvals, DNOW and MRC Global will each hold special meetings of their respective stockholders in connection with the mergers (respectively, the “DNOW special meeting” and the “MRC Global special meeting”).

At the DNOW special meeting, the DNOW stockholders will be asked to vote on (1) a proposal to approve the issuance of shares of DNOW common stock to the MRC Global stockholders (the “DNOW stock issuance proposal”) and (2) a proposal to approve the adjournment of the DNOW special meeting to solicit additional proxies if there are not sufficient votes at the time of the DNOW special meeting to approve the DNOW stock issuance proposal (the “DNOW adjournment proposal”).

Approval of each of the DNOW stock issuance proposal and the DNOW adjournment proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. The mergers cannot be completed without the approval of the DNOW stock issuance proposal. For the avoidance of doubt, approval of the DNOW adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

##### Table of Contents

The DNOW special meeting will be held on      , 2025 at  :  a.m., Central Time, at the offices of DNOW, located at 7402 North Eldridge Parkway, Houston, Texas 77041. DNOW’s board of directors unanimously recommends that DNOW stockholders (i) vote “FOR” the DNOW stock issuance proposal and (ii) vote “FOR” the DNOW adjournment proposal.

At the MRC Global special meeting, MRC Global stockholders will be asked to vote on (1) a proposal to adopt and approve the merger agreement, the mergers and the other transactions contemplated thereby (the “MRC Global merger proposal”), (2) a proposal to approve, on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s named executive officers that is based on or otherwise relates to the mergers (the “MRC Global compensation advisory proposal”) and (3) a proposal to approve the adjournment of the MRC Global special meeting to solicit additional proxies if there are not sufficient votes at the time of the MRC Global special meeting to approve the MRC Global merger proposal (the “MRC Global adjournment proposal”).

Approval of the MRC Global merger proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on such proposal. Approval of the MRC Global compensation advisory proposal, on a non-binding advisory basis, and the MRC Global adjournment proposal requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. The mergers cannot be completed without the approval of the MRC Global merger proposal. For the avoidance of doubt, neither the approval of the MRC Global compensation advisory proposal nor the approval of the MRC Global adjournment proposal is a condition to the closing of the mergers or otherwise required to effectuate the mergers.

The MRC Global special meeting will be held on      , 2025, at  :  a.m., Central Time at the offices of MRC Global located at 1301 McKinney Street, Suite 2300, Houston, Texas 77010. The board of directors of MRC Global unanimously recommends that the MRC Global stockholders (i) vote “FOR” the MRC Global merger proposal, (ii) vote “FOR” the MRC Global compensation advisory proposal and (iii) vote “FOR” the MRC Global adjournment proposal.

Although the number of shares of DNOW common stock that MRC Global stockholders will receive in exchange for their shares of MRC Global common stock is fixed, the market value of the merger consideration will fluctuate with the market price of DNOW common stock and will not be known at the time MRC Global stockholders vote to adopt and approve the merger agreement or at the time DNOW stockholders vote to approve the DNOW stock issuance proposal. Based on the closing price of DNOW common stock on the New York Stock Exchange (“NYSE”) on June 25, 2025, the last trading day before the public announcement of the parties entering into the merger agreement, the merger consideration represented approximately $13.85 in value for each share of MRC Global common stock. Based on the closing price of MRC Global common stock on the NYSE on     , 2025, the last practicable trading day before the date of the accompanying joint proxy statement/prospectus, the merger consideration represented approximately $     in value for each share of MRC Global common stock.

DNOW common stock and MRC Global common stock are traded on the NYSE under the ticker symbols “DNOW” and “MRC,” respectively. We urge you to obtain current market quotations for DNOW common stock and MRC Global common stock.

The obligations of DNOW and MRC Global to complete the mergers are subject to the satisfaction or waiver of a number of conditions set forth in the merger agreement, a copy of which is attached as Annex A to the accompanying joint proxy statement/prospectus.

The accompanying joint proxy statement/prospectus describes the DNOW special meeting and the DNOW stock issuance proposal to be considered thereat, the MRC Global special meeting and the MRC Global merger proposal and the MRC Global compensation advisory proposal to be considered thereat, and the mergers. Please carefully read the entire accompanying joint proxy statement/prospectus, including “Risk Factors” beginning on page 30, for a discussion of the risks relating to the mergers. You also can obtain information about DNOW and MRC Global from documents that each has filed with the U.S. Securities and Exchange Commission (the “SEC”). Please see “Where You Can Find More Information” beginning on page 185 of the accompanying joint proxy statement/prospectus for how you may obtain such information.

QUESTIONS AND ANSWERS

The following are some questions that you may have regarding the mergers, the DNOW stock issuance and other matters being considered at the DNOW special meeting and MRC Global special meeting and the answers to those questions. DNOW and MRC Global urge you to carefully read the entirety of this joint proxy statement/prospectus, including the annexes hereto and the information incorporated by reference herein, because the information in this section does not provide all the information that might be important to you with respect to the mergers, the DNOW stock issuance and the other matters being considered at the DNOW special meeting and the MRC Global special meeting.

Q: Why am I receiving this joint proxy statement/prospectus?

A: You are receiving this joint proxy statement/prospectus because DNOW and MRC Global have agreed to merge their respective businesses and have entered into the merger agreement, pursuant to which, on the terms and subject to the conditions included in the merger agreement, (1) Merger Sub will be merged with and into MRC Global, with MRC Global continuing as the surviving corporation in the First Merger, and (2) immediately following the First Merger, MRC Global will be merged with and into LLC Sub, with LLC Sub continuing as the surviving company in the Second Merger as a wholly-owned, direct subsidiary of DNOW. The merger agreement, which governs the terms of the transactions, is attached to this joint proxy statement/prospectus as Annex A.

Completion of the mergers requires, among other things, the separate approvals of both the DNOW stockholders and the MRC Global stockholders. To obtain the required stockholder approvals, DNOW and MRC Global will each hold special meetings of their respective stockholders in connection with the mergers.

At the DNOW special meeting, the DNOW stockholders will be asked to vote on the DNOW stock issuance proposal and the DNOW adjournment proposal. Approval of the DNOW stock issuance proposal and the DNOW adjournment proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting.

At the MRC Global special meeting, MRC Global stockholders will be asked to vote on the MRC Global merger proposal, the MRC Global compensation advisory proposal and the MRC Global adjournment proposal. Approval of the MRC Global merger proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on such proposal. Approval of the MRC Global compensation advisory proposal, on a non-binding advisory basis, and the MRC Global adjournment proposal requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting.

The mergers cannot be completed without the approval of the DNOW stock issuance proposal and the MRC Global merger proposal. The approval of the DNOW adjournment proposal, the MRC Global compensation advisory proposal and the MRC Global adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

This joint proxy statement/prospectus, which you should read carefully, contains important information about the mergers, the DNOW stock issuance, the MRC Global compensation advisory proposal and other matters being considered at the DNOW special meeting and the MRC Global special meeting.

Q: When and where is the DNOW special meeting?

A: The DNOW special meeting will be held on , 2025 at : a.m., Central Time, at the offices of DNOW, located at 7402 North Eldridge Parkway, Houston, Texas 77041.

Q: What will MRC Global stockholders receive for their shares of MRC Global common stock?

A: At the Effective Time, subject to certain exceptions, each Eligible MRC Global share will be converted automatically into the right to receive 0.9489 shares of DNOW common stock, with cash paid in lieu of the issuance of fractional shares, if any.

In addition, each outstanding MRC Global restricted share, MRC Global RSU and MRC Global PSU will be treated as described in “The Merger Agreement — Treatment of MRC Global Equity Awards in the Mergers.”

For additional information regarding the consideration to be received in the mergers, please see “The Mergers.”

Q: If I am a holder of MRC Global common stock, how will I receive the merger consideration to which I am entitled?

A: If you are a holder of record, as of immediately prior to the Effective Time, of certificates that represent the Eligible MRC Global shares (“MRC Global certificates”), a letter of transmittal and instructions for the surrender of your MRC Global certificates in exchange for the merger consideration will be mailed to you as soon as practicable after the Effective Time but in no event more than three business days after the closing date. After receiving proper documentation from you, the exchange agent will send to you (i) with respect to MRC Global certificates of Eligible MRC Global shares, a statement reflecting the aggregate whole number of shares of DNOW common stock (which will be in uncertificated book-entry form) that you have a right to receive pursuant to the merger agreement and (ii) a check in the amount equal to the cash payable in lieu of any fractional shares of DNOW common stock, and any dividends or distributions on the shares of DNOW common stock issuable to you under the merger agreement.

If you are a holder of record, as of immediately prior to the Effective Time of Eligible MRC Global shares represented by book-entry (“MRC Global book-entry securities”) which are not held through The Depository Trust Company (“DTC”), the exchange agent will deliver to you (i) a statement reflecting the aggregate whole number of shares of DNOW common stock (which will be in uncertificated book-entry form) that you have a right to receive pursuant to the merger agreement and (ii) a check in the amount equal to the cash payable in lieu of any fractional shares of DNOW common stock, and any dividends or distributions on the shares of DNOW common stock issuable to you as merger consideration.

If you are a holder of record of MRC Global book-entry securities which are held through DTC, the exchange agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the closing date, the merger consideration, cash in lieu of any fractional shares of DNOW common stock and any dividends or distributions on the shares of DNOW common stock issuable under the merger agreement, in each case, that DTC has the right to receive.

Q: What will holders of MRC Global equity awards receive in the mergers?

A: The merger agreement provides that each MRC Global restricted share that is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest in full immediately prior to the Effective Time and (ii) be canceled and converted into the right to receive (A) the merger consideration with respect to each MRC Global restricted share, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the merger agreement and (B) an amount in cash equal to the accrued but unpaid dividends with respect to each MRC Global restricted share.

The merger agreement also provides that each MRC Global RSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest in full immediately prior to the Effective Time (including with respect to any dividend equivalents credited with respect to such MRC Global RSU that remain unpaid as of the Effective Time) and (ii) be canceled and converted into the right to receive the merger consideration with respect to each share of MRC Global common stock subject to such MRC Global RSU, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the merger agreement.

The merger agreement also provides that each MRC Global RSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, be canceled and converted into an award of restricted stock units representing the right to receive DNOW common stock (each a “DNOW RSU”) in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the total number of shares of MRC Global common stock subject to such award of MRC Global RSUs immediately prior to the Effective Time multiplied by (2) 0.9489. Such DNOW RSUs will vest on the same terms and conditions (including “double-trigger” vesting provisions) applicable to the corresponding MRC Global RSU immediately prior to the Effective Time.

The merger agreement also provides that, to the extent provided for in the applicable award agreement, each MRC Global PSU that was granted prior to February 2024 and that is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest immediately prior to the Effective Time with respect to a number of shares of MRC Global common stock that vest based on the determination of performance set forth in the applicable award agreement (including with respect to any dividend equivalents credited with respect to such MRC Global PSU that remain unpaid as of the Effective Time) and (ii) be canceled and converted into the right to receive, without interest, the merger consideration with respect to each share of MRC Global common stock that vests pursuant to such MRC Global PSU, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the merger agreement.

The merger agreement also provides that, to the extent provided for in the applicable award agreement, each outstanding MRC Global PSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time shall be canceled and converted into a DNOW RSU award in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the number of shares of MRC Global common stock that vest based on the determination of performance set forth in the applicable award agreement multiplied by (2) 0.9489. Such DNOW RSUs will vest on the same terms and conditions (including “double-trigger” vesting provisions) applicable to the corresponding MRC Global PSU immediately prior to the Effective Time (except that such DNOW RSUs will no longer be subject to performance metrics).

For additional information on the treatment of MRC Global equity awards, please see “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers — Treatment of MRC Global Equity Awards in the Mergers” and “The Merger Agreement — Treatment of MRC Global Equity Awards in the Mergers.”

Q: How will DNOW stockholders be affected by the mergers?

A: Upon completion of the mergers, each holder of DNOW common stock will hold the same number of shares of DNOW common stock that such holder held immediately prior to completion of the mergers. As a

##### Table of Contents

result of the mergers, DNOW stockholders would own shares in a larger company with more assets. However, because DNOW will be issuing additional shares of DNOW common stock to holders of Eligible MRC Global shares, each share of DNOW common stock issued and outstanding immediately prior to the mergers will represent a smaller percentage of the aggregate number of shares of DNOW common stock issued and outstanding after the mergers.

Q: What will happen to MRC Global as a result of the mergers?

A: If the mergers are completed, Merger Sub will merge with and into MRC Global, with MRC Global surviving such merger as a direct, wholly-owned subsidiary of DNOW, and the separate corporate existence of Merger Sub will cease. Immediately thereafter, MRC Global will merge with and into LLC Sub, with LLC Sub continuing its existence as the surviving company and a direct, wholly-owned subsidiary of DNOW. Furthermore, shares of MRC Global common stock will be delisted from the NYSE and will no longer be publicly traded.

Q: Who would own DNOW immediately following the mergers?

A: Following the closing of the mergers, based on the number of shares of DNOW common stock outstanding as of the date of the merger agreement, DNOW’s existing stockholders would own approximately 56.5% of the issued and outstanding shares of the combined company and MRC Global’s existing stockholders would own approximately 43.5% of the issued and outstanding shares of the combined company, in each case on a fully diluted basis. The exact equity stake of MRC Global stockholders in DNOW immediately following the Effective Time will depend on the number of shares of DNOW common stock and shares of MRC Global common stock issued and outstanding immediately prior to the Effective Time.

Q: What will be the composition of the board of directors and management of DNOW following the completion of the mergers?

A: Pursuant to the terms of the merger agreement, prior to the Effective Time, DNOW is required to take all actions as may be necessary to cause the number of directors constituting the board of directors of DNOW as of the Effective Time to be increased by two members to a total of ten members, including two directors selected from MRC Global’s board of directors by DNOW prior to closing. On July 17, 2025, DNOW notified MRC Global that DNOW had selected George J. Damiris and Ronald L. Jadin to be appointed to the DNOW board effective immediately upon closing. Certain, if not all, of the current executive officers of DNOW are expected to continue as officers of the combined company following the mergers.

Q: Why are MRC Global stockholders being asked to vote on named executive officer compensation?

A: The SEC has adopted rules that require MRC Global to seek a non-binding advisory vote on certain compensation that may be paid or become payable to the named executive officers (“NEOs”) of MRC Global that is based on or otherwise relates to the mergers. MRC Global urges its stockholders to read the section entitled “The Mergers —Interests of Certain MRC Global Directors and Executive Officers in the Mergers” beginning on page 106.

Q: How important is my vote?

A: Your vote “FOR” each proposal presented at the DNOW special meeting and MRC Global special meeting is very important, and you are encouraged to submit a proxy as soon as possible. The mergers cannot be completed without the approval of the DNOW stock issuance proposal and the MRC Global merger proposal. The approval of the DNOW adjournment proposal, the MRC Global compensation advisory proposal and the MRC Global adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

##### Table of Contents

DNOW. Approval of the DNOW stock issuance proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. Abstentions will have the same effect as a vote AGAINST the DNOW stock issuance proposal and the DNOW adjournment proposal. We do not expect there to be broker-non votes.

MRC Global. Approval of the MRC Global merger proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on such proposal. Approval of the MRC Global compensation advisory proposal, on a non-binding advisory basis, and the MRC Global adjournment proposal requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. Abstentions will have the same effect as a vote AGAINST the MRC Global merger proposal. Abstentions will not be treated as votes cast and, therefore, will have no effect on the outcome of the MRC Global compensation advisory proposal and the MRC Global adjournment proposal.

Q: How do the DNOW board and the MRC Global board recommend that I vote?

A: The DNOW board unanimously recommends that DNOW stockholders vote (i) “FOR” the DNOW stock issuance proposal and (ii) “FOR” the DNOW adjournment proposal. For additional information regarding how the DNOW board recommends DNOW stockholders vote, see the section entitled “The Mergers — Recommendation of the DNOW Board and Reasons for the Mergers.”

The MRC Global board unanimously recommends that MRC Global stockholders vote (i) “FOR” the MRC Global merger proposal, (ii) “FOR” the MRC Global compensation advisory proposal and (iii) “FOR” the MRC Global adjournment proposal. For additional information regarding how the MRC Global board recommends that MRC Global stockholders vote, see the section entitled “The Mergers — Recommendation of the MRC Global Board and Reasons for the Mergers.”

Q: Will the shares of DNOW common stock received following the mergers be traded on an exchange?

A: Yes. It is a condition to the consummation of the mergers that the shares of DNOW common stock to be issued pursuant to the merger agreement be authorized for listing on the NYSE, subject to official notice of issuance. MRC Global common stock currently trades on the NYSE under the stock symbol “MRC.” When the mergers are completed, the MRC Global common stock will cease to be traded on the NYSE and will be deregistered under the Exchange Act. The DNOW common stock to be issued in connection with the mergers will be registered under the Securities Act and will be freely transferable under the Securities Act and the Exchange Act.

Q: What are the material U.S. federal income tax consequences of the mergers to MRC Global stockholders?

A: Assuming that the mergers are completed as currently contemplated, DNOW and MRC Global intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Provided that the mergers, taken together, qualify as a “reorganization” within the meaning of Section 368(a) of the Code, a U.S. holder (as defined in the section entitled “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers” beginning on page 114) of shares of MRC Global common stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of MRC Global common stock for shares of DNOW common stock pursuant to the mergers, except with respect to any cash received in lieu of fractional shares of DNOW common stock. The completion of the mergers is not conditioned on the mergers qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or IRS ruling to that effect.

Please see “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers” for a more detailed discussion of the U.S. federal income tax consequences of the mergers to U.S. holders of shares of MRC

Q: When do DNOW and MRC Global expect to complete the mergers?

A: DNOW and MRC Global currently expect to complete the mergers by the fourth quarter of 2025. However, neither DNOW nor MRC Global can predict the actual date on which the mergers will be completed, nor can the parties ensure that the mergers will be completed, because completion is subject to conditions beyond the control of either company. In addition, if the mergers are not completed by June 26, 2026 (or, under certain circumstances, by September 26, 2026 or December 26, 2026), either DNOW or MRC Global may choose not to proceed with the mergers by terminating the merger agreement. Please see “The Mergers — Regulatory Approvals,” “The Merger Agreement — Conditions to Completion of the Mergers” and “The Merger Agreement — Termination of the Merger Agreement.”

Q: What are the conditions to the completion of the mergers?

A: The mergers are subject to a number of conditions to closing as specified in the merger agreement. These closing conditions include, among others, (i) the approval of the MRC Global merger proposal by MRC Global stockholders, (ii) the approval of the DNOW stock issuance proposal by DNOW stockholders, (iii) the expiration or termination of any waiting period under the HSR Act, applicable to the mergers and receipt of certain non-U.S. antitrust and foreign direct investment approvals, (iv) no law or order being in effect that prohibits the consummation of the mergers, (v) the registration statement containing this proxy statement/prospectus having become effective under the Securities Act and not being the subject of any stop order or proceedings seeking a stop order and (vi) the shares of DNOW common stock issuable pursuant to the merger agreement having been authorized for listing on the NYSE. More information may be found in “The Merger Agreement — Conditions to Completion of the Mergers” beginning on page 145.

Q: What happens if the requisite stockholder approvals are not obtained or the mergers are not completed?

A: If the MRC Global merger proposal is not approved by the MRC Global stockholders, the DNOW stock issuance proposal is not approved by DNOW stockholders or the mergers are not completed for any other reason, MRC Global stockholders will not receive any merger consideration for shares of MRC Global common stock they own. Instead, MRC Global will remain an independent public company, MRC Global common stock will continue to be listed and traded on the NYSE and registered under the Exchange Act and MRC Global will continue to file periodic reports with the SEC.

Under specified circumstances, MRC Global or DNOW may be required to pay a termination fee upon or subsequent to termination of the merger agreement, or may also be required to reimburse certain expenses incurred by the other party, as described in “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement.”

| • |  | delivering a valid, later-dated proxy, or a later-dated vote by telephone or on the Internet until 11:59 p.m. (Eastern Time) on , 2025.

Please note that if you are a beneficial owner, you may vote by submitting voting instructions to your broker, bank or other nominee, or otherwise by following instructions provided by your broker, bank or other nominee. Phone and Internet voting may be available to beneficial owners. Please refer to the voting instruction form provided by your broker, bank or other nominee. For additional information, please see “MRC Global Special Meeting.”

Q: What should I do if I receive more than one set of voting materials for the DNOW special meeting or the MRC Global special meeting?

A: You may receive more than one set of voting materials for the DNOW special meeting, the MRC Global special meeting, or both, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction forms. For example, if you hold your shares of DNOW common stock or your shares of MRC Global common stock in more than one brokerage account, you will receive a separate voting instruction form for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please submit each separate proxy or voting instruction form that you receive by following the instructions set forth in each separate proxy or voting instruction form. If you fail to submit each separate proxy or voting instruction form that you receive, not all of your shares will be voted.

A: If your shares of DNOW common stock are registered directly in your name with DNOW’s transfer agent, Equiniti Trust Company, LLC, or your shares of MRC Global common stock are registered directly in your name with MRC Global’s transfer agent, Computershare Trust Company, N.

If your shares of DNOW common stock or MRC Global common stock are held through a bank, broker or other nominee, you are considered, with respect to those shares, the beneficial owner, and those shares are held in

“street name” by your bank, broker or other nominee. In that case, this joint proxy statement/prospectus has been forwarded to you by your bank, broker or other nominee. As the beneficial owner, you have the right to direct your bank, broker or other nominee how to vote your shares by following their instructions for voting, and you are also invited to attend the DNOW special meeting or the MRC Global special meeting, as applicable. However, because you are not the stockholder of record, you may not vote your shares of DNOW common stock or MRC Global common stock, as applicable, at the applicable special meeting unless you request and obtain a “legal proxy” issued in your own name from your bank, broker or other nominee.

Q: If my shares of DNOW common stock or MRC Global common stock are held in “street name” by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote my shares for me?

A: No. If your shares of DNOW common stock or MRC Global common stock are held in the name of a bank, broker or other nominee, you will receive separate instructions from your bank, broker or other nominee describing how to vote your shares. The availability of internet or telephonic voting will depend on the nominee’s voting process. Please check with your bank, broker or other nominee and follow the voting procedures provided by your bank, broker or other nominee on your voting instruction form.

You should instruct your bank, broker or other nominee how to vote your shares of DNOW common stock or MRC Global common stock, as applicable. Under the rules applicable to broker-dealers, your bank, broker or other nominee does not have discretionary authority to vote your shares on any of the proposals scheduled to be voted on at the DNOW special meeting or the MRC Global special meeting. A so-called “broker non-vote” results when banks, brokers and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares. DNOW and MRC Global do not expect any broker non-votes at the DNOW special meeting or the MRC Global special meeting because the rules applicable to brokers, banks and other nominees only provide them with discretionary authority to vote on proposals that are considered routine, whereas each of the proposals to be presented at the DNOW special meeting and MRC Global special meeting are considered non-routine. As a result, no broker will be permitted to vote your shares at the DNOW special meeting or the MRC Global special meeting without receiving instructions. Failure to instruct your broker, bank or other nominee on how to vote your shares will have no effect on the outcome of the proposals to be considered at the DNOW special meeting or the MRC Global special meeting and such shares will not be counted as present in person or by proxy at the DNOW special meeting or the MRC Global special meeting for purposes of determining a quorum.

For additional information on voting procedures, please see “DNOW Special Meeting” and “MRC Global Special Meeting.”

Q: What do I do if I am a DNOW stockholder and I want to revoke my proxy?

A: DNOW stockholders may revoke a proxy before the voting polls are closed at the DNOW special meeting, by the following methods:

| • |  | voting at a later time by Internet or telephone until 11:59 p.m. (Eastern Time) on , 2025;

| • |  | voting in person at the DNOW special meeting;

| • |  | delivering to the DNOW Secretary a proxy with a later date or a written revocation of the most recent proxy; or

| • |  | giving notice to the inspector of elections at the DNOW special meeting.

DNOW stockholders that hold their shares in street name (for example, shares held in the name of a bank, broker or other holder of record) and vote by proxy may later revoke such proxy by informing the holder of record in accordance with that entity’s procedures.

Q: What do I do if I am an MRC Global stockholder and I want to revoke my proxy?

A: MRC Global stockholders may revoke a proxy before it is exercised by:

| • |  | giving written notice to MRC Global’s Corporate Secretary;

| • |  | delivering a valid, later-dated proxy, or a later-dated vote by telephone or on the Internet until 11:59 p.m. (Eastern Time) on , 2025; or

| • |  | attending and voting in person at the MRC Global special meeting.

Beneficial owners of shares of MRC Global common stock may submit new voting instructions by contacting their broker, bank or other holder of record.

For additional information, please see “MRC Global Special Meeting.”

Q: Are there any risks that I should consider as a DNOW stockholder or MRC Global stockholder in deciding how to vote?

A: Yes. You should read and carefully consider the risks set forth in “Risk Factors.” You also should read and carefully consider the risk factors of DNOW and MRC Global contained in the documents that are incorporated by reference into this joint proxy statement/prospectus.

Q: What happens if I sell or otherwise transfer my shares of DNOW common stock before the DNOW special meeting?

A: The DNOW record date is prior to the date of the DNOW special meeting. If you sell or otherwise transfer your shares of DNOW common stock after the DNOW record date but before the DNOW special meeting, unless special arrangements are made between you and the person to whom you transfer your shares of DNOW common stock (such as provision of a proxy), you will retain your right to vote such shares at the DNOW special meeting but will otherwise transfer ownership of and the economic interest in your shares of DNOW common stock.

Q: What happens if I sell or otherwise transfer my shares of MRC Global common stock before the MRC Global special meeting?

A: The MRC Global record date is prior to the date of the MRC Global special meeting. If you sell or otherwise transfer your shares of MRC Global common stock after the MRC Global record date but before the MRC Global special meeting, unless special arrangements are made between you and the person to whom you transfer your shares of MRC Global common stock (such as provision of a proxy), you will retain your right to vote such shares at the MRC Global special meeting but will otherwise transfer ownership of and the economic interest in your shares of MRC Global common stock.

Q: What happens if I sell or otherwise transfer my shares of MRC Global common stock before the completion of the mergers?

A: Only MRC Global stockholders as of immediately prior to the Effective Time will become entitled to receive the merger consideration.

Q: If I am a holder of MRC Global common stock certificates, do I need to send in my stock certificates at this time to receive the merger consideration?

A: No. Please DO NOT send your MRC Global common stock certificates with your proxy card. You should carefully review and follow the instructions set forth in the letter of transmittal, which will be mailed to you, regarding the surrender of your stock certificates.

Q: Do any of the officers or directors of DNOW have interests in the mergers that may differ from or be in addition to my interests as a DNOW stockholder?

A: In considering the recommendation of the DNOW board that DNOW stockholders vote to approve the DNOW stock issuance proposal, DNOW stockholders should be aware that, aside from their interests as DNOW stockholders, DNOW’s directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of DNOW stockholders generally. These interests are described in more detail in the section entitled “The Mergers — Interests of Certain DNOW Directors and Executive Officers in the Mergers.” The DNOW board was aware of and considered these potential interests, among other matters, in evaluating and negotiating the merger agreement and the transactions contemplated thereby, in approving the merger and in recommending the approval of the DNOW stock issuance proposal. See “The Mergers —Background of the Mergers” and “The Mergers — Recommendation of the DNOW Board and Reasons for the Mergers” and “Board of Directors and Management of DNOW Following Completion of the Mergers.”

Q: Do any of the officers or directors of MRC Global have interests in the mergers that may differ from or be in addition to my interests as an MRC Global stockholder?

A: In considering the recommendation of the MRC Global board that MRC Global stockholders vote to approve the MRC Global merger proposal and the MRC Global compensation advisory proposal, MRC Global stockholders should be aware that, aside from their interests as MRC Global stockholders, MRC Global’s directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of MRC Global stockholders generally. These interests are described in more detail in the section entitled “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers.” The MRC Global board was aware of and considered these potential interests, among other matters, in evaluating and negotiating the merger agreement and the other transactions contemplated thereby, in approving the merger and in recommending the approval of the MRC Global merger proposal and the MRC Global compensation advisory proposal. See “The Mergers — Background of the Mergers” and “The Mergers — Recommendation of the MRC Global Board and Reasons for the Mergers.”

Q: If I am a DNOW stockholder and I oppose the DNOW stock issuance proposal or if I am an MRC Global stockholder and I oppose the MRC Global merger proposal or the MRC Global compensation advisory proposal, but all such proposals are approved, what are my rights?

A: Under the DGCL, DNOW stockholders are not entitled to dissenters’ or appraisal rights in connection with the DNOW stock issuance as contemplated by the merger agreement. DNOW stockholders may vote against the DNOW stock issuance proposal if they do not favor such proposal.

Because shares of DNOW common stock are listed on the NYSE and holders of Eligible MRC Global shares are not required to receive consideration other than shares of DNOW common stock, which are listed on the NYSE, and any cash received in lieu of fractional shares of DNOW common stock as contemplated by the merger agreement, holders of Eligible MRC Global shares are not entitled to exercise dissenters’ or appraisal rights under Delaware law in connection with the mergers.

At the Effective Time and by virtue of the First Merger, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time will be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the surviving corporation and will constitute the only outstanding shares of capital stock of the surviving corporation immediately following the Effective Time. From and after the Effective Time, all certificates representing the common stock of Merger Sub

will be deemed for all purposes to represent the number of shares of common stock of the surviving corporation into which they were converted in accordance with the immediately preceding sentence.

At the effective time of the Second Merger and by virtue of the Second Merger, (i) each share of capital stock of MRC Global, as the surviving corporation of the First Merger, issued and outstanding immediately prior to the time the Second Merger becomes effective will be converted into and will represent one validly issued, fully paid and nonassessable (except as nonassessability may be affected by matters described in Section 18-607 of the DLLCA) unit of LLC Sub, as the surviving company of the Second Merger, and (ii) each unit of LLC Sub will be unaffected by the Second Merger and will remain outstanding as a unit of LLC Sub, as the surviving company of the Second Merger.

DNOW Special Meeting (see page 45)

The DNOW special meeting will be held on , 2025, at : a.m., Central Time at the offices of DNOW, located at 7402 North Eldridge Parkway, Houston, Texas 77041. The DNOW special meeting is being held to consider and vote on a proposal to approve the issuance of shares of DNOW common stock to MRC Global stockholders in connection with the mergers pursuant to the terms of the merger agreement.

The record date for the determination of DNOW stockholders entitled to notice of and to vote at the DNOW special meeting is the close of business on , 2025. Only DNOW stockholders who held DNOW common stock of record on the DNOW record date are entitled to vote at the DNOW special meeting and any adjournments or postponements of the DNOW special meeting. Each issued and outstanding share of DNOW common stock entitles its holder of record to one vote on each matter to be considered at the DNOW special meeting.

For business to be conducted at the DNOW special meeting, a quorum must be present. A quorum at the DNOW special meeting requires the presence, in person or by proxy, of the holders of a majority of the stock issued and outstanding and entitled to vote in the election of directors. Abstentions will be counted for purposes of determining whether there is a quorum at the DNOW special meeting. In accordance with Section 2(b) of the DNOW bylaws, the chairman of the meeting of stockholders may adjourn the meeting from time to time, regardless of the outcome of the DNOW adjournment proposal. At any subsequent reconvening of the DNOW special meeting at which a quorum shall be present or represented, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the DNOW special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Approval of each of the DNOW stock issuance proposal and the DNOW adjournment proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. Abstentions will have the same effect as a vote AGAINST the DNOW stock issuance proposal and the DNOW adjournment proposal. We do not expect there to be broker-non votes.

The mergers cannot be completed without the approval of the DNOW stock issuance proposal. The approval of the DNOW adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

As of the DNOW record date, there were shares of DNOW common stock issued and outstanding, held by holders of record. As of the DNOW record date, DNOW directors and executive officers, and their affiliates, as a group, beneficially owned and were entitled to vote shares of DNOW common stock, or approximately % of the combined voting power of the issued and outstanding shares of DNOW common stock.

MRC Global Special Meeting (see page 53)

The MRC Global special meeting will be held on , 2025, at : a.m., Central Time at the offices of MRC Global, located at 1301 McKinney Street, Suite 2300, Houston, Texas 77010. The MRC Global special meeting is being held to consider and vote on a proposal to adopt and approve the merger agreement, the mergers and the other transactions contemplated thereby, a proposal to approve, on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s NEOs that is based on or otherwise relates to the mergers and a proposal to approve the adjournment of the MRC Global special meeting to solicit additional proxies if there are not sufficient votes at the time of the MRC Global special meeting to approve the MRC Global merger proposal.

The record date for the determination of MRC Global’s stockholders entitled to notice of and to vote at the MRC Global special meeting is the close of business on , 2025. Only MRC Global stockholders who held MRC Global common stock of record on the MRC Global record date are entitled to vote at the MRC Global special meeting and any adjournments or postponements of the MRC Global special meeting. Each issued and outstanding share of MRC Global common stock entitles its holder of record to one vote on each matter to be considered at the MRC Global special meeting.

For business to be conducted at the MRC Global special meeting, a quorum must be present. A quorum at the MRC Global special meeting constitutes the holders of not less than a majority of the voting power of all the shares entitled to vote at the MRC Global special meeting, present in person or by proxy. Abstentions will be counted in determining that a quorum is present for the MRC Global special meeting. In accordance with Article II, Section 8 of the MRC Global bylaws, the chairman of the MRC Global special meeting may adjourn the MRC Global special meeting to another place, if any, date and time, regardless of the outcome of the MRC Global adjournment proposal. At any subsequent reconvening of the MRC Global special meeting at which a quorum shall be present or represented, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the MRC Global special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Approval of the MRC Global merger proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on such proposal. Accordingly, an MRC Global stockholder’s abstention from voting, the failure of an MRC Global stockholder to vote or the failure of an MRC Global stockholder to submit a proxy will have the same effect as a vote AGAINST the MRC Global merger proposal.

Approval of the MRC Global compensation advisory proposal, on a non-binding advisory basis, and the MRC Global adjournment proposal requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. Accordingly, an MRC Global stockholder’s abstention from voting or the failure of an MRC Global stockholder to vote will have no effect on the outcome of the MRC Global compensation advisory proposal and the MRC Global adjournment proposal.

Opinion of DNOW’s Financial Advisor (see page 92 and Annex B)

Goldman Sachs & Co. LLC (“Goldman Sachs”) delivered its opinion to the DNOW board that, as of June 26, 2025 and based upon and subject to the factors and assumptions set forth therein, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to DNOW.

The full text of the written opinion of Goldman Sachs, dated June 26, 2025, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B to this joint proxy statement/prospectus. Goldman Sachs provided advisory services and its opinion for the information and assistance of the DNOW board in connection with its consideration of the mergers. Goldman Sachs’ opinion is not a recommendation as to how any holder of DNOW’s common stock should vote with respect to the transactions contemplated by the merger agreement or any other matter. Pursuant to an engagement letter between DNOW and Goldman Sachs, DNOW has agreed to pay Goldman Sachs a transaction fee of approximately $19 million, $3 million of which became payable upon the announcement of the mergers, and the remainder of which is contingent upon consummation of the mergers. Goldman Sachs may receive an additional fee of up to $3 million at DNOW’s sole discretion.

Opinion of MRC Global’s Financial Advisor (see page 100 and Annex C)

At the meeting of the MRC Global board on June 26, 2025, J.P. Morgan Securities LLC (“J.P. Morgan”) rendered to the MRC Global board its oral opinion to the effect that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review that J.P. Morgan undertook in preparing its opinion, the exchange ratio in the proposed First Merger was fair, from a financial point of view, to the MRC Global stockholders. J.P. Morgan confirmed its June 26, 2025 oral opinion by delivering its written opinion, dated June 26, 2025, to the MRC Global board that, as of such date, the exchange ratio in the proposed First Merger was fair, from a financial point of view, to the MRC Global stockholders.

The full text of the written opinion of J.P. Morgan, dated June 26, 2025, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review that J.P.

incorporated in this joint proxy statement/prospectus by reference. The summary of J.P. Morgan’s opinion set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. The MRC Global stockholders are urged to read the opinion in its entirety. J.P. Morgan’s opinion was addressed to the MRC Global board (in its capacity as such) in connection with and for the purposes of its evaluation of the mergers, and was limited to the fairness, from a financial point of view, of the exchange ratio in the proposed First Merger to the MRC Global stockholders. J.P. Morgan expressed no opinion as to the fairness of any consideration to be paid in connection with the mergers to the holders of any other class of securities, creditors or other constituencies of MRC Global or as to MRC Global’s underlying decision to engage in the mergers. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any stockholder of MRC Global as to how such stockholder should vote with respect to the mergers or any other matter.

Interests of Certain DNOW Directors and Executive Officers in the Mergers (see page 106)

When considering the recommendation of the DNOW board that DNOW stockholders vote “FOR” the DNOW stock issuance proposal, DNOW stockholders should be aware that certain of DNOW’s directors and executive officers have interests in the mergers that are different from, or in addition to, the interests of other DNOW stockholders generally. The DNOW board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that DNOW stockholders vote “FOR” the DNOW stock issuance proposal. Such interests include that certain, if not all, of the current directors and executive officers of DNOW are expected to continue as directors and executive officers of DNOW following consummation of the mergers.

The mergers do not constitute a “change in control” for purposes of the DNOW executives’ or non-employee directors’ equity award arrangements. Accordingly, there are no payments or benefits to DNOW NEOs that are based on or otherwise relate to the mergers. Upon completion of the mergers, certain, if not all, of the current executive officers of DNOW and all members of DNOW’s board of directors are expected to continue in their current roles with the combined company, as described in “The Mergers — Board of Directors and Management of DNOW Following Completion of the Mergers.”

Interests of Certain MRC Global Directors and Executive Officers in the Mergers (see page 106)

In considering the recommendation of the MRC Global board that MRC Global’s stockholders vote to approve the MRC Global merger proposal and the MRC Global compensation advisory proposal, MRC Global’s stockholders should be aware that, aside from their interests as MRC Global stockholders, MRC Global’s directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of MRC Global’s stockholders generally. These interests are described in more detail in the section entitled “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers.”

The MRC Global board was aware of and considered these potential interests, among other matters, in evaluating and negotiating the merger agreement and the transactions contemplated in the merger agreement, in approving the mergers and in recommending the approval of the MRC Global merger proposal and the MRC Global compensation advisory proposal. See “The Mergers — Background of the Mergers” and “The Mergers — Recommendation of the MRC Global Board and Reasons for the Mergers.” MRC Global’s stockholders should take these interests into account in deciding whether to vote “FOR” the MRC Global merger proposal and the MRC Global compensation advisory proposal. These interests are described in more detail in the section entitled “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers.”

##### Table of Contents

Board of Directors and Management of DNOW Following Completion of the Mergers (see page 114)

Pursuant to the terms of the merger agreement, prior to the Effective Time, DNOW is required to take all actions as may be necessary to cause the number of directors constituting the board of directors of DNOW as of the Effective Time to be increased by two members to a total of ten members, including two directors selected from MRC Global’s board of directors by DNOW prior to closing. On July 17, 2025, DNOW notified MRC Global that DNOW had selected George J. Damiris and Ronald L. Jadin to be appointed to the DNOW board effective immediately upon closing. Certain, if not all, of the current executive officers of DNOW are expected to continue as officers of the combined company following the mergers.

Material U.S. Federal Income Tax Consequences of the Mergers (see page 114)

Assuming that the mergers are completed as currently contemplated, DNOW and MRC Global intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Provided that the mergers, taken together, qualify as a “reorganization” within the meaning of Section 368(a) of the Code, a U.S. holder (as defined in the section entitled “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers” beginning on page 114) of shares of MRC Global common stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of MRC Global common stock for shares of DNOW common stock pursuant to the mergers, except with respect to any cash received in lieu of fractional shares of DNOW common stock. The completion of the mergers is not conditioned on the mergers qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or IRS ruling to that effect.

Please see “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers” for a more detailed discussion of the U.S. federal income tax consequences of the mergers to U.S. holders of shares of MRC Global common stock. Each MRC Global stockholder is strongly encouraged to consult with a tax advisor to determine the particular U.S. federal, state or local or non-U.S. income or other tax consequences of the mergers to such stockholder.

Accounting Treatment of the Mergers (see page 118)

DNOW and MRC Global prepare their respective financial statements in accordance with GAAP. The accounting guidance for business combinations provides for the use of the acquisition method of accounting for the mergers, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any. DNOW will be treated as the acquirer for accounting purposes. DNOW is the entity issuing the equity of the combined company. The composition of the management team and, thereby, the overall decision-making power of the combined company will be more heavily dominated by DNOW executives. Additionally, the legacy DNOW headquarters in Houston, Texas will remain the headquarters of the combined company. Each of these factors holds significant strategic implications for the combined company and, when combined with the inapplicability or relative neutrality of all other indicators considered, results in the conclusion that DNOW is the accounting acquirer.

Regulatory Approvals (see page 118)

Antitrust Clearance

Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the rules promulgated thereunder, the mergers cannot be completed until the parties to the merger agreement have given notification and furnished information to the Federal Trade Commission (the “FTC”) and the United States Department of Justice (the “DOJ”), and until the applicable waiting period has expired or has been terminated. If the DOJ or FTC issues a Request for Additional Information and Documentary Material (a “second request”) prior to the expiration of the initial 30-day waiting period, the mergers cannot close until the expiration of a

20

##### Table of Contents

second 30-day waiting period, and which would begin to run only after both parties have substantially complied with the second request, unless the second waiting period is terminated earlier.

On , 2025, DNOW and MRC Global each filed a premerger notification and report form under the HSR Act.

At any time before or after consummation of the mergers, the FTC or the DOJ, or any state, could take such action under antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the mergers or to conditionally permit completion of the mergers subject to regulatory concessions or conditions, such as seeking the divestiture of substantial assets of DNOW or MRC Global or their respective subsidiaries. Private parties may also seek to take legal action under antitrust laws under certain circumstances.

Although neither DNOW nor MRC Global believes that the mergers will violate the antitrust laws, there can be no assurance that a challenge to the mergers on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful.

Under the terms of the merger agreement, the parties also are required to file all applicable notices, reports or other draft filings (as applicable) with respect to any non-U.S. antitrust and foreign direct investment screening processes determined to be reasonably required or advisable pursuant to the applicable antitrust and foreign direct investment laws as promptly as reasonably practical (but in no event later than 40 business days following the date of the merger agreement). The completion of the mergers is subject making these filings with, and obtaining authorizations, approvals or consents from, the relevant non-U.S. antitrust and foreign direct investment authorities or until the applicable waiting period has expired or been terminated.

U.S. Securities and Exchange Commission

In connection with the DNOW stock issuance proposal, DNOW has filed a registration statement on Form S-4, of which this joint proxy statement/prospectus forms a part, that must be declared effective by the SEC and pursuant to which the issuance of shares of DNOW common stock issuable under the merger agreement in the mergers will be registered with the SEC.

The New York Stock Exchange

The completion of the mergers is subject to approval for listing of the shares of DNOW common stock to be issued pursuant to the merger agreement on the NYSE, subject to official notice of issuance.

Listing of DNOW Common Stock; Delisting and Deregistration of MRC Global Common Stock (see page 120)

It is a condition to the consummation of the mergers that the shares of DNOW common stock to be issued pursuant to the merger agreement be approved for listing on the NYSE, subject to official notice of issuance.

Shares of MRC Global common stock currently trade on the NYSE under the stock symbol “MRC.” When the mergers are completed, the MRC Global common stock will cease to be traded on the NYSE and will be deregistered under the Exchange Act.

Appraisal Rights and Dissenters’ Rights (see page 120)

DNOW

Under the DGCL, DNOW stockholders are not entitled to dissenters’ or appraisal rights in connection with the DNOW stock issuance as contemplated by the merger agreement. See “The Mergers — Appraisal Rights and Dissenters’ Rights.”

21

##### Table of Contents

MRC Global

Under the DGCL, MRC Global stockholders are not entitled to dissenters’ or appraisal rights in connection with the MRC Global merger proposal. See “The Mergers — Appraisal Rights and Dissenters’ Rights.”

Completion of the Mergers (see page 122)

The consummation of the mergers will take place on a date to be mutually agreed upon by DNOW and MRC Global, which date will be no later than the second business day after the satisfaction or, to the extent permitted by applicable law, waiver in accordance with the terms of the merger agreement of the conditions to closing (other than any such conditions which by their nature cannot be satisfied until the closing date, which will be required to be so satisfied or (to the extent permitted by applicable law) waived in accordance with the merger agreement on the closing date), or such other time as the parties will mutually agree.

Immediately following the closing and on the closing date, MRC Global will cause the first certificate of merger to be executed and filed with the Secretary of State of the State of Delaware in accordance with the DGCL to effect the First Merger. The First Merger will become effective upon such filing and acceptance of the first certificate of merger with the Secretary of State of the State of Delaware, or at such later date and time as agreed by DNOW and MRC Global and as set forth in the first certificate of merger. Immediately following the Effective Time and on the closing date, MRC Global, as the surviving corporation of the First Merger, and LLC Sub will cause the second certificate of merger to be executed and filed with the Secretary of State of the State of Delaware in accordance with the DGCL and DLLCA to effect the Second Merger. The Second Merger will become effective one minute after the Effective Time, which MRC Global, as the surviving corporation of the First Merger, and LLC Sub will specify in the second certificate of merger.

DNOW and MRC Global have targeted to complete the mergers in the fourth quarter of 2025, subject to the receipt of the required approval of DNOW stockholders and approval of MRC Global stockholders, applicable regulatory approvals and the satisfaction or waiver of the other conditions to the mergers, in each case, as set forth in the merger agreement.

Treatment of MRC Global Equity Awards in the Mergers (see page 135)

The merger agreement provides that, at the Effective Time, each MRC Global restricted share that is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, immediately vest with respect to 100% of the MRC Global restricted shares, which MRC Global restricted shares will be converted into the right to receive (A) the merger consideration with respect to each share of MRC Global common stock and (B) an amount in cash equal to the accrued but unpaid dividends with respect to such MRC Global restricted shares, in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, (i) at the Effective Time, each MRC Global RSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, immediately vest with respect to 100% of the shares of MRC Global common stock subject to such MRC Global RSU, which shares of MRC Global common stock will be converted into the right to receive (A) the merger consideration with respect to each share of MRC Global common stock, reduced by the number of shares of DNOW common stock required or permitted to be deducted to satisfy applicable withholding and similar taxes and (B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such MRC Global RSU, if any, less applicable withholding and similar taxes, in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

22

##### Table of Contents

The merger agreement also provides that, at the Effective Time, each outstanding MRC Global RSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will be canceled and converted into an award of DNOW RSUs in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the total number of shares of DNOW common stock subject to such award of MRC Global RSUs immediately prior to the Effective Time multiplied by (2) the exchange ratio. Such DNOW RSU will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in DNOW common stock).

The merger agreement also provides that, at the Effective Time, each MRC Global PSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, be canceled, and the holder thereof will then become entitled to receive, in full satisfaction of the rights of such holder with respect thereto, the number of shares of MRC Global common stock (rounded to the nearest share) subject to the MRC Global PSU, which shares of MRC Global common stock will be converted into the right to receive (A) the merger consideration with respect to each share of MRC Global common stock subject to such MRC Global PSU that vest based on the determination of performance set forth in the applicable award agreement, reduced by the number of shares of DNOW common stock required or permitted to be deducted to satisfy applicable withholding and similar taxes and (B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such MRC Global PSU, if any, less applicable withholding and similar taxes, in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, at the Effective Time, each outstanding MRC Global PSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will be canceled and converted into a DNOW RSU in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the number of shares of MRC Global common stock subject to such MRC Global PSU immediately prior to the Effective Time that vest based on the determination of performance set forth in the applicable award agreement multiplied by (2) the exchange ratio. Such DNOW RSU will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in DNOW common stock and such award will no longer be subject to performance metrics). For purposes of the immediately preceding sentence, the number of shares of MRC Global common stock subject to such MRC Global PSU will be deemed to be the number of shares subject to the MRC Global PSU with performance deemed achieved, except as previously disclosed to DNOW, in accordance with the terms and conditions of the applicable award agreement governing such MRC Global PSU immediately prior to the Effective Time.

To the extent that any award described herein constitutes nonqualified deferred compensation subject to Section 409A of the Code, any payment contemplated hereby with respect to such award will be made in accordance with the merger agreement and the applicable award’s terms or, if later, at the earliest time permitted under the terms of such award that will not result in the application of a tax or penalty under Section 409A of the Code.

No Solicitation; Changes in Recommendation (see page 136)

Subject to certain exceptions, the merger agreement limits DNOW’s and MRC Global’s ability to solicit or engage in discussions with any person with respect to a DNOW superior proposal or an MRC Global superior proposal (as defined in “The Merger Agreement — No Solicitation; Changes in Recommendation”), as applicable.

The merger agreement may be terminated and the mergers may be abandoned at any time prior to the Effective Time, whether before or after the approval of the MRC Global stockholders or the DNOW stockholders, at the discretion of the governing bodies of DNOW or MRC Global, as applicable, by mutual written consent of DNOW and MRC Global, or by either DNOW or MRC Global under certain circumstances. For a more detailed discussion on DNOW and MRC Global and their ability to terminate the merger agreement, please see “The Merger Agreement — Termination of the Merger Agreement.”

Expenses and Termination Fees Relating to the Termination of the Merger Agreement (see page 148)

Termination Fees Payable by MRC Global

The merger agreement requires MRC Global to pay DNOW a termination fee of $45.5 million if:

| • |  | the merger agreement is terminated by DNOW pursuant to the MRC Global board effecting an MRC Global adverse recommendation change (as defined in the merger agreement) or MRC Global is in material breach of its non-solicitation obligations under the merger agreement;

| • |  | the merger agreement is terminated by MRC Global pursuant to the receipt of an MRC Global superior proposal;

| • |  | the merger agreement is terminated by either party pursuant to the passing of the outside date and (A) the approval of MRC Global stockholders has not been obtained upon a vote held at a duly held MRC Global stockholders’ meeting, or at any adjournment or postponement thereof, and (B) DNOW would have been permitted to terminate the merger agreement pursuant to an MRC Global adverse recommendation change or MRC Global’s material breach of its non-solicitation obligations under the merger agreement; or

| • |  | if (A) prior to the DNOW stockholders’ meeting, a DNOW acquisition proposal is publicly proposed or publicly disclosed, (B) the merger agreement is terminated by either party pursuant to the passing of the outside date or the failure to obtain the approval of DNOW stockholders, or by MRC Global pursuant to DNOW’s terminable breach, (C) concurrently with or within nine months after such termination described in clause (B), MRC Global or any MRC Global’s subsidiaries enters into a definitive agreement with respect to, or otherwise consummates, any MRC Global acquisition proposal (substituting 50% for the 15% threshold set forth in the definition of “Acquisition Proposal”).

In no event will DNOW be entitled to receive more than one payment of the termination fee.

Expenses

The merger agreement requires DNOW to pay certain of MRC Global’s expenses if the merger agreement is terminated by either MRC Global or DNOW because the required approval of DNOW stockholders is not obtained; provided that the aggregate amount of reimbursable expenses will not exceed $8.5 million.

The merger agreement requires MRC Global to pay certain of DNOW’s expenses if the merger agreement is terminated by either DNOW or MRC Global because the required approval of MRC Global stockholders is not obtained; provided that the aggregate amount of reimbursable expenses will not exceed $8.5 million.

Except for the payment of expenses described above, each of DNOW and MRC Global will pay its own expenses incurred in connection with the merger agreement and the transactions contemplated thereby, whether or not the mergers are consummated.

If MRC Global or DNOW receives a termination fee, then the party receiving the termination fee will not be entitled to also receive a payment for the expenses as described above, and if the termination fee is payable after such party has already received payment or concurrently receives payment in respect of the expenses, the amount of the expenses received will be deducted from the termination fee.

Specific Performance (see page 150)

DNOW and MRC Global agreed that irreparable damage would occur if any provision of the merger agreement is not performed in accordance with its specific terms or is otherwise breached. The parties agree that, in the event of any breach by the other party of any covenant or obligation contained in the merger agreement, the other party will be entitled (in addition to any other remedy that may be available to it, including monetary damages) to obtain (a) a decree or order of specific performance to enforce the observance and performance of

26

##### Table of Contents

such covenant or obligation and (b) an injunction restraining such breach. The parties further agree that no party to the merger agreement will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy in the merger agreement and each party waives any objection to the imposition of such relief or any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Comparison of Stockholder Rights (see page 173)

MRC Global stockholders receiving DNOW common stock in connection with the mergers will have different rights once they become DNOW stockholders due to differences between the governing documents of DNOW and MRC Global. These differences are described in more detail in “Comparison of Stockholder Rights.”

Risk Factors (see page 30)

MARKET PRICE INFORMATION

DNOW common stock is listed on the NYSE under the symbol “DNOW.” MRC Global common stock is listed on the NYSE under the symbol “MRC.”

The high and low trading prices for the DNOW common stock as of June 25, 2025, the last trading day immediately before the public announcement of the mergers, were $15.19 and $14.54, respectively. The high and low trading prices for the MRC Global common stock as of June 25, 2025, the last trading day immediately before the public announcement of the mergers, were $13.13 and $12.92, respectively.

As of , 2025, the last date before the date of this joint proxy statement/prospectus for which it was practicable to obtain this information, there were shares of DNOW common stock outstanding and shares of MRC Global common stock outstanding.

Because the exchange ratio will not be adjusted for changes in the market price of either DNOW common stock or MRC Global common stock, the market value of DNOW common stock that MRC Global stockholders will have the right to receive on the date the mergers are completed may vary significantly from the market value of the DNOW common stock that MRC Global stockholders would receive if the mergers were completed on the date of this joint proxy statement/prospectus. As a result, you should obtain recent market prices of DNOW common stock and MRC Global common stock prior to voting your shares. Please see “Risk Factors — Risks Relating to the Mergers.”

The following table sets forth the closing sale price per share of DNOW common stock as reported on the NYSE and the closing sale price per share of MRC Global common stock as reported on the NYSE, in each case on June 25, 2025, the last trading day before the public announcement of the parties entering into the merger agreement, and on , 2025, the last practicable trading day prior to the mailing of this joint proxy statement/prospectus. The table also shows the estimated implied value of the merger consideration as of the same two dates. The implied value was calculated by multiplying the NYSE closing price of a share of DNOW common stock on the relevant date by the exchange ratio of 0.9489 shares of DNOW common stock for each share of MRC Global common stock.

RISK FACTORS

In deciding how to vote, DNOW stockholders and MRC Global stockholders, respectively, should carefully consider the following risk factors and all of the information contained in or incorporated by reference herein, including, but not limited to, the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements” as well as DNOW’s and MRC Global’s other filings with the SEC incorporated herein by reference. Please see “Where You Can Find More Information.”

Risks Relating to the Mergers

Because the market price of DNOW common stock will fluctuate, holders of Eligible MRC Global shares and holders of MRC Global equity awards cannot be sure of the value of the shares of DNOW common stock they will receive in connection with the mergers. In addition, because the exchange ratio is fixed, the number of shares of DNOW common stock to be received by holders of Eligible MRC Global shares and to which holders of MRC Global equity awards would be entitled in connection with the mergers will not change between now and the time the mergers are completed to reflect changes in the trading prices of DNOW common stock or MRC Global common stock.

In connection with the mergers, (i) each Eligible MRC Global share will be converted into the right to receive 0.9489 shares of DNOW common stock, with cash paid in lieu of the issuance of fractional shares, if any. The exchange ratio is fixed, which means that it will not change between now and the closing date, regardless of whether the market price of either DNOW common stock or MRC Global common stock changes. Therefore, the value of the share consideration will depend on the market price of DNOW common stock at the Effective Time. The market price of DNOW common stock has fluctuated since the date of the announcement of the parties’ entry into the merger agreement and will continue to fluctuate from the date of this joint proxy statement/prospectus to the date of the special meetings, the date the mergers are completed and thereafter. The market price of DNOW common stock, when received by holders of Eligible MRC Global shares after the mergers are completed, could be greater than, less than or the same as the market price of DNOW common stock on the date of this joint proxy statement/prospectus or at the time of the MRC Global special meeting. Accordingly, you should obtain current stock price quotations for DNOW common stock and MRC Global common stock before deciding how to vote or abstain from voting on any of the proposals described in this joint proxy statement/prospectus.

The market price for DNOW common stock following the closing may be affected by factors different from those that historically have affected or currently affect DNOW common stock and MRC Global common stock.

Upon completion of the mergers, holders of Eligible MRC Global shares and holders of MRC Global equity awards will receive shares of DNOW common stock. DNOW’s financial position may differ from its financial position before the completion of the mergers, and the results of operations of the combined company may be affected by some factors that are different from those currently affecting the results of operations of DNOW and those currently affecting the results of operations of MRC Global.

Accordingly, the market price and performance of DNOW common stock is likely to be different from the performance of MRC Global common stock in the absence of the mergers. In addition, general fluctuations in stock markets could have a material adverse effect on the market for, or liquidity of, DNOW common stock, regardless of DNOW’s actual operating performance. For a discussion of the businesses of DNOW and MRC Global, and important factors to consider in connection with those businesses, see the documents attached hereto or incorporated by reference and referred to in “Where You Can Find More Information.”

DNOW stockholders and MRC Global stockholders, in each case as of immediately prior to the mergers, will have reduced ownership in the combined company.

Following the closing, based on the number of shares of DNOW common stock outstanding as of the date of the merger agreement, DNOW’s existing stockholders would own approximately 56.5% of the issued and

30

##### Table of Contents

outstanding shares of the combined company and MRC Global’s existing stockholders would own approximately 43.5% of the issued and outstanding shares of the combined company, in each case on a fully diluted basis. As a result, DNOW’s current stockholders and MRC Global’s current stockholders will have less influence on the policies of the combined company than they currently have on the policies of DNOW and MRC Global, respectively.

MRC Global stockholders are not entitled to appraisal rights in connection with the mergers.

Appraisal rights are statutory rights that enable stockholders to dissent from certain extraordinary transactions, such as certain mergers, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the applicable transaction. Under the DGCL, MRC Global stockholders are not entitled to dissenters’ or appraisal rights in connection with the MRC Global merger proposal. Please see “The Mergers — Appraisal Rights and Dissenters’ Rights.”

The mergers are subject to a number of conditions to the obligations of both DNOW and MRC Global to complete the mergers, which, if not fulfilled, or not fulfilled in a timely manner, may delay completion of the mergers or result in termination of the merger agreement.

The obligations of DNOW and MRC Global to consummate the mergers are subject to the satisfaction (or waiver by all parties, to the extent permissible under applicable laws) of the conditions described in “The Merger Agreement — Conditions to Completion of the Mergers.”

Many of the conditions to completion of the mergers are not within either DNOW’s or MRC Global’s control, and neither company can predict when, or if, these conditions will be satisfied. If any of these conditions are not satisfied or waived prior to the outside date, it is possible that the merger agreement may be terminated. Although DNOW and MRC Global have agreed in the merger agreement to use reasonable best efforts or commercially reasonable efforts, as the case may be with respect to certain conditions, and subject to certain limitations, to promptly complete the mergers, these and other conditions to the completion of the mergers may fail to be satisfied.

For example, the closing of the mergers is conditioned upon the expiration or termination of any applicable waiting period, or any extension thereof, under the HSR Act and any applicable waiting period, clearance or affirmative or deemed approval of any governmental entity or other condition with respect to certain non-U.S. antitrust or foreign direct investment approvals having expired or been terminated, or been obtained or satisfied, as applicable. There can be no assurance that the relevant waiting periods will expire or that the relevant authorizations will be obtained. In addition, certain non-U.S. governmental authorities with or from which these authorizations are required have broad discretion in administering the governing regulations. Adverse developments in DNOW’s or MRC Global’s regulatory standing or any other factors considered by regulators in granting such approvals; governmental, political or community group inquiries, investigations or opposition; or changes in legislation or the political environment generally could affect whether and when required governmental authorizations are granted. As a condition to authorization of the mergers, governmental authorities may impose requirements, limitations or costs or place restrictions on the conduct of DNOW’s business after completion of the mergers.

Satisfying the conditions to and completion of the mergers may take longer, and could cost more, than DNOW and MRC Global expect. Neither DNOW nor MRC Global can predict whether and when these other conditions will be satisfied. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying or preventing the closing of the mergers or imposing additional material costs on or materially limiting the revenues of the combined company following the mergers, or otherwise adversely affecting DNOW’s businesses and results of operations after completion of the mergers. Any delay in completing the mergers may

31

##### Table of Contents

adversely affect the cost savings and other benefits that DNOW and MRC Global expect to achieve if the mergers and the integration of the companies’ respective businesses are completed within the expected timeframe. There can be no assurance that all required regulatory approvals will be obtained prior to the outside date or at all.

DNOW and MRC Global may waive one or more of the closing conditions without re-soliciting stockholder approval.

DNOW and MRC Global may determine to waive, in whole or part, one or more of the conditions to closing prior to consummating the mergers. Any determination whether to waive any conditions to closing, or to re-solicit stockholder approval to amend or supplement this proxy statement/prospectus as a result of such a waiver, will be made by DNOW or MRC Global at the time of such waiver based on the facts and circumstances as they exist at that time.

Uncertainties associated with the mergers may cause a loss of management personnel and other key employees of DNOW and MRC Global, which could adversely affect the future business and operations of the combined company following the mergers.

DNOW and MRC Global are dependent on the experience and industry knowledge of their respective officers and other key employees to execute their business plans. The combined company’s success after the mergers will depend in part upon its ability to retain key management personnel and other key employees of both DNOW and MRC Global. Current and prospective employees of DNOW and MRC Global may experience uncertainty about their roles within the combined company following the mergers or other concerns regarding the timing and completion of the mergers or the operations of the combined company following the mergers, any of which may have an adverse effect on the ability of DNOW and MRC Global to retain or attract key management and other key personnel. If DNOW or MRC Global are unable to retain personnel, including key management, who are critical to the future operations of the companies, DNOW and MRC Global could face disruptions in their operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment and training costs. In addition, the loss of key personnel could diminish the anticipated benefits of the mergers. No assurance can be given that the combined company will be able to retain or attract key management personnel and other key employees to the same extent that DNOW and MRC Global have previously been able to retain or attract their own employees.

The business relationships of DNOW and MRC Global may be subject to disruption due to uncertainty associated with the mergers, which could have a material adverse effect on the results of operations, cash flows and financial position of DNOW or MRC Global prior to the mergers, and on the combined company following the mergers.

Parties with which DNOW or MRC Global do business may experience uncertainty associated with the mergers, including with respect to current or future business relationships with DNOW, MRC Global or the combined company following the mergers. DNOW’s and MRC Global’s business relationships may be subject to disruption as customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners may attempt to delay or defer entering into new business relationships, negotiate changes in existing business relationships or consider entering into business relationships with parties other than the combined company following the mergers. These disruptions could have a material adverse effect on the results of operations, cash flows and financial position of DNOW or MRC Global, regardless of whether the mergers are completed, as well as a material and adverse effect on the combined company’s ability to realize the expected cost savings and other benefits of the mergers. The risk, and adverse effect, of any disruption could be exacerbated by a delay in completion of the mergers or termination of the merger agreement.

32

##### Table of Contents

The merger agreement subjects DNOW and MRC Global to restrictions on their respective business activities prior to the Effective Time.

The merger agreement obligates each of DNOW and MRC Global to generally use commercially reasonable efforts to conduct its businesses in the ordinary course, including by using commercially reasonable efforts to preserve substantially intact its present business organization, goodwill and assets and preserve its existing relationships with governmental entities and its significant customers, suppliers and others having significant business dealings with it. These restrictions could prevent DNOW and MRC Global from pursuing certain business opportunities that arise prior to the Effective Time and are outside the ordinary course of business. See “The Merger Agreement — Conduct of Business” for additional details.

The combined company may record goodwill and other intangible assets that could become impaired and result in material non-cash charges to the results of operations of the combined company in the future.

The merger will be accounted for as an acquisition by DNOW in accordance with GAAP principles. Under the acquisition method of accounting, the assets and liabilities of MRC Global and its subsidiaries will be recorded, as of completion, at their respective fair values and added to those of DNOW. The reported financial condition and results of operations of DNOW for periods after completion of the merger will reflect MRC Global balances and results after completion of the merger but will not be restated retroactively to reflect the historical financial position or results of operations of MRC Global and its subsidiaries for periods prior to the mergers. For additional information, see the section entitled “Unaudited Pro Forma Combined Financial Statements.”

Under the acquisition method of accounting, the total purchase price will be allocated to MRC Global’s tangible assets and liabilities and identifiable intangible assets based on their fair values as of the date of completion of the mergers. The excess of the purchase price over those fair values will be recorded as goodwill. DNOW and MRC Global expect that the merger may result in the creation of goodwill based upon the application of the acquisition method of accounting. To the extent goodwill or intangibles are recorded and the values become impaired, the combined company may be required to recognize material non-cash charges relating to such impairment. The combined company’s operating results may be significantly impacted from both the impairment and the underlying trends in the business that triggered the impairment.

If the integrated mergers, taken together, do not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, MRC Global stockholders may be required to recognize gain or loss for U.S. federal income tax purposes.

DNOW and MRC Global intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is expected that U.S. holders (as defined in the section entitled “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers” beginning on page 114) of shares of MRC Global common stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of MRC Global common stock for shares of DNOW common stock pursuant to the mergers, except with respect to any cash received in lieu of fractional shares of DNOW common stock. The completion of the mergers is not conditioned on the mergers qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or IRS ruling to that effect. If the IRS or a court determines that the mergers are not treated as a “reorganization” within the meaning of Section 368(a) of the Code, a U.S. holder generally would recognize taxable gain or loss upon the exchange of MRC Global common stock for DNOW common stock pursuant to the mergers. See the section entitled “The Mergers — Material U.S. Federal Income Tax Consequences of the Mergers.”

MRC Global directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of the MRC Global stockholders generally.

In considering the recommendation of the MRC Global board that MRC Global stockholders vote in favor of the MRC Global merger proposal and the MRC Global compensation advisory proposal, MRC Global

33

##### Table of Contents

stockholders should be aware of and take into account the fact that, aside from their interests as MRC Global stockholders, certain MRC Global directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of MRC Global stockholders generally. These interests are described in more detail in the section entitled “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers” for a more detailed description of these interests. The MRC Global board was aware of and considered these potential interests, among other matters, in evaluating the terms and structure, and overseeing the negotiation, of the mergers, in approving the merger agreement and the transactions contemplated thereby, and in recommending that MRC Global stockholders vote in favor of the MRC Global merger proposal and the MRC Global compensation advisory proposal.

The merger agreement limits DNOW’s and MRC Global’s respective ability to pursue alternatives to the mergers, which may discourage other companies from making a favorable alternative transaction proposal and, in specified circumstances, could require DNOW or MRC Global to pay the other party a termination fee.

The merger agreement contains certain provisions that restrict each of DNOW’s and MRC Global’s ability to initiate, solicit, propose, knowingly encourage or knowingly facilitate any inquiry or the making of any proposal or offer that constitutes, or would reasonably be expected to result in, an acquisition proposal, as described in “The Merger Agreement — No Solicitation; Changes in Recommendation,” and DNOW and MRC Global have each agreed to certain terms and conditions relating to their ability to engage in, continue or otherwise participate in any discussions with respect to, provide a third party confidential information with respect to or enter into any acquisition agreement with respect to certain unsolicited proposals that constitute or are reasonably likely to lead to an acquisition proposal. DNOW and MRC Global generally have an opportunity to offer to modify the terms of the merger agreement in response to any superior proposals or intervening events before the MRC Global board or DNOW board, respectively, may withdraw or qualify their respective recommendations. For more information, see the section entitled “The Merger Agreement — No Solicitation; Changes in Recommendation.” The merger agreement further provides that, under specified circumstances, including after receipt of certain alternative acquisition proposals, MRC Global may be required to pay DNOW a cash termination fee equal to $45.5 million or DNOW may be required to pay MRC Global a cash termination fee equal to $45.5 million. See “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” for additional details.

While both MRC Global and DNOW believe these provisions to be reasonable and customary and are not preclusive of other offers, these provisions could discourage a potential third-party acquirer or other strategic transaction partner that might have an interest in acquiring all or a significant portion of MRC Global or DNOW from considering or pursuing an alternative transaction with either party or proposing such a transaction, even if it were prepared, in MRC Global’s case, to pay consideration with a higher per share value than the total value proposed to be paid or received in the mergers. These provisions might also result in a potential third-party acquirer or other strategic transaction partner proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances.

Failure to complete the mergers could negatively impact DNOW’s or MRC Global’s stock price and have a material adverse effect on their results of operations, cash flows and financial position.

If the mergers are not completed for any reason, including as a result of failure to obtain all requisite regulatory approvals or if the DNOW stockholders or MRC Global stockholders fail to approve the applicable requisite proposals, the ongoing businesses of DNOW and MRC Global may be materially adversely affected and, without realizing any of the benefits of having completed the mergers, DNOW and MRC Global would be subject to a number of risks, including the following:

| • |  | DNOW and MRC Global may experience negative reactions from the financial markets, including negative impacts on their respective stock prices;

34

##### Table of Contents

| • |  | DNOW and MRC Global and their respective subsidiaries may experience negative reactions from their respective customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners;

| • |  | DNOW and MRC Global will still be required to pay certain significant costs relating to the mergers, such as legal, accounting, financial advisor and printing fees;

| • |  | DNOW or MRC Global may be required to pay a termination fee or other expenses as required by the merger agreement;

| • |  | the merger agreement places certain restrictions on the conduct of the respective businesses pursuant to the terms thereof, which may delay or prevent the respective companies from undertaking business opportunities that, absent the merger agreement, may have been pursued;

| • |  | matters relating to the mergers (including integration planning) require substantial commitments of time and resources by each company’s management, which may have resulted in the distraction of each company’s management from ongoing business operations and pursuing other opportunities that could have been beneficial to the companies; and

| • |  | litigation related to any failure to complete the mergers or related to any enforcement proceeding commenced against DNOW, Merger Sub, MRC Global or LLC Sub to perform their respective obligations pursuant to the merger agreement.

If the mergers are not completed, the risks described above may materialize and they may have a material adverse effect on DNOW’s or MRC Global’s results of operations, cash flows, financial position and stock prices.

The shares of DNOW common stock to be received by MRC Global stockholders upon completion of the mergers will have different rights from shares of MRC Global common stock.

Upon completion of the mergers, MRC Global stockholders will no longer be MRC Global stockholders. Instead, former MRC Global stockholders will become DNOW stockholders and, while their rights as DNOW stockholders will continue to be governed by the laws of the state of Delaware, their rights will be subject to and governed by the terms of the DNOW certificate of incorporation and the DNOW bylaws. The terms of the DNOW certificate of incorporation and the DNOW bylaws are in some respects different than the terms of the MRC Global certificate of incorporation and the MRC Global bylaws, which currently govern the rights of MRC Global stockholders. See “Comparison of Stockholder Rights” for a discussion of the different rights associated with shares of DNOW common stock and shares of MRC Global common stock.

Completion of the mergers may trigger change in control or other provisions in certain agreements to which DNOW or MRC Global is a party.

As of March 31, 2025, MRC Global had approximately $371 million of total long-term debt outstanding (net of unamortized debt issuance costs and original issue discounts), consisting of $27 million of borrowings outstanding under MRC Global’s revolving credit facility (the “MRC Global credit facility”) and $344 million of borrowings outstanding under MRC Global’s term loan credit facility (the “MRC Global term loan facility”). Pursuant to the merger agreement, MRC Global will deliver at or prior to the closing date (i) a payoff letter to DNOW setting forth the amount outstanding under the MRC Global credit facility and (ii) a payoff letter to DNOW setting forth the amount outstanding under the MRC Global term loan facility. For a description of DNOW’s and MRC Global’s existing indebtedness, see DNOW’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, filed on May 7, 2025, and MRC Global’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, filed on May 7, 2025, each of which is incorporated by reference into this joint proxy statement/prospectus.

The completion of the mergers may trigger change in control or other provisions in certain agreements to which DNOW or MRC Global is a party. If DNOW and MRC Global are unable to negotiate waivers or

35

amendments of those provisions, the counterparties may exercise their rights and remedies under such agreements, potentially terminating such agreements, or seeking monetary damages. Even if DNOW and MRC Global are able to negotiate waivers or amendments, the counterparties may require a fee for such waivers or amendments or seek to renegotiate such agreements on terms less favorable to DNOW or MRC Global.

The completion of the mergers will, unless waived, constitute a change of control under MRC Global’s credit facility and under MRC Global’s term loan facility. As a result of a change of control, at the direction of the lenders holding a majority of the outstanding loans under the MRC Global credit facility and at the direction of the lenders holding a majority of the outstanding loans under the MRC Global term loan facility, the commitments under each may be terminated and the outstanding balance under the MRC Global credit facility and the MRC Global term loan facility may be accelerated and become due and payable by in connection with the completion of the mergers. However, MRC Global is permitted to incur borrowings under the MRC Global credit facility during the interim period between the execution of the merger agreement and the closing, subject to certain limitations set forth in the merger agreement. The merger agreement contains a condition requiring DNOW to have sufficient funds at closing to pay off the outstanding indebtedness, if any, under the MRC Global credit facility and the MRC Global term loan facility.

DNOW and MRC Global are expected to incur significant transaction costs in connection with the mergers, which may be in excess of those anticipated by them.

DNOW and MRC Global have incurred and are expected to continue to incur a number of non-recurring costs associated with negotiating and completing the mergers, combining the operations of the two companies and achieving desired synergies. These costs have been, and will continue to be, substantial and, in many cases, will be borne by DNOW and MRC Global regardless of whether the mergers are completed. A substantial majority of non-recurring expenses will consist of transaction costs and include, among others, fees paid to financial, legal, accounting and other advisors, employee retention, severance and benefit costs, and filing fees. DNOW will also incur costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and other employment-related costs. DNOW and MRC Global will continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in connection with the mergers and the integration of the two companies’ businesses. While DNOW and MRC Global have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the expenses. The elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may not offset integration-related costs and achieve a net benefit in the near term, or at all. The costs described above and any unanticipated costs and expenses, many of which will be borne by DNOW or MRC Global even if the mergers are not completed, could have an adverse effect on DNOW’s or MRC Global’s business, financial condition and results of operations.

Litigation relating to the mergers could result in an injunction preventing the completion of the mergers and/or substantial costs to DNOW and MRC Global.

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, mergers or other business combination agreements. Defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on DNOW’s and MRC Global’s business, financial condition and results of operations.

Lawsuits that may be brought against DNOW, MRC Global or their respective directors could also seek, among other things, injunctive relief or other equitable relief, including a request to rescind parts of the merger agreement already implemented and to otherwise enjoin the parties from consummating the mergers. One of the conditions to the closing of the mergers is that no injunction by any court or other tribunal of competent jurisdiction has been entered and continues to be in effect and no law has been adopted or is effective, in either case that prohibits or makes illegal the closing of the mergers. Consequently, if a plaintiff is successful in

36

##### Table of Contents

obtaining an injunction prohibiting completion of the mergers, that injunction may delay or prevent the mergers from being completed within the expected timeframe or at all, which may adversely affect DNOW’s and MRC Global’s respective business, financial condition and results of operations.

There can be no assurance that any of the defendants will be successful in the outcome of any pending or any potential future lawsuits. The defense or settlement of any lawsuit or claim that remains unresolved at the time the mergers are completed may adversely affect DNOW’s or MRC Global’s business, financial condition and results of operations.

The merger may not be accretive, and may be dilutive, to DNOW’s earnings per share, which may negatively affect the market price of DNOW common stock.

Because shares of DNOW common stock will be issued in the mergers, it is possible that the mergers may be dilutive to DNOW’s earnings per share. This outcome could negatively affect the market price of DNOW common stock. The issuance of new shares of DNOW common stock in connection with the mergers could have the effect of depressing the market price of DNOW common stock, through dilution of earnings per share or otherwise. Any dilution of, or delay of any accretion to, DNOW’s earnings per share could cause the price of shares of DNOW common stock to decline or increase at a reduced rate.

Risks Relating to the Combined Company Following the Mergers

The combined company may be unable to integrate the business of DNOW and MRC Global successfully or realize the anticipated benefits of the mergers.

The mergers involve the combination of two companies that currently operate as independent public companies. The combination of two independent businesses is complex, costly and time consuming, and each of DNOW and MRC Global will be required to devote significant management attention and resources to integrating the business practices and operations of MRC Global into DNOW. Potential difficulties that DNOW and MRC Global may encounter as part of the integration process include the following:

| • |  | the inability to successfully combine the business of DNOW and MRC Global in a manner that permits the combined company to achieve, on a timely basis, or at all, the enhanced revenue opportunities and cost savings and other benefits anticipated to result from the mergers;

| • |  | complexities associated with managing the combined businesses, including difficulty addressing possible differences in operational philosophies and the challenge of integrating complex systems, technology, networks and other assets of each of the companies in a seamless manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;

| • |  | the assumption of contractual obligations with less favorable or more restrictive terms; and

| • |  | potential unknown liabilities and unforeseen increased expenses or delays associated with the mergers.

In addition, DNOW and MRC Global have operated and, until the completion of the mergers, will continue to operate, independently. It is possible that the integration process could result in:

| • |  | diversion of the attention of each company’s management; and

| • |  | the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies.

Any of these issues could adversely affect each company’s ability to maintain relationships with customers, suppliers, employees and other constituencies or achieve the anticipated benefits of the mergers or could reduce each company’s earnings or otherwise adversely affect the business and financial results of the combined company following the mergers.

The maintenance of any share repurchase programs and the declaration, payment and amounts of dividends, if any, distributed to stockholders of the combined company will be uncertain.

In January 2025, the DNOW board authorized a share repurchase program to purchase up to $160 million of DNOW common stock, and the MRC Global board also authorized a share repurchase program to purchase up to $125 million of MRC Global common stock. Neither DNOW nor MRC Global have paid cash dividends on DNOW common stock or MRC Global common stock, respectively in the past and the combined company board may determine not to declare dividends in the future. Although it is expected that the combined company will continue to maintain a share repurchase program, the maintenance of any share repurchase program and the payment of any future dividends will be at the sole discretion of the combined company board and will depend on the combined company’s results of operations, financial condition, cash requirements, future prospects and other considerations that the combined company board deems relevant, including, but not limited to:

| • |  | the combined company may not have enough cash to pay any future dividends or to repurchase shares due to its cash requirements, capital spending plans, cash flow or financial position;

| • |  | decisions on whether, when and in which amounts to make any future dividends or share repurchases will remain at all times entirely at the discretion of the combined company board, which could change its practices at any time and for any reason;

| • |  | the combined company’s desire to obtain, maintain or improve credit ratings on its debt;

| • |  | the amount of dividends that the combined company may distribute to its stockholders and the amount of shares that the combined company may repurchase are each subject to restrictions under Delaware law; and

| • |  | the agreements governing the combined company’s indebtedness.

Stockholders should be aware that they have no contractual or other legal right to dividends that have not been declared or to the repurchase of their shares.

The trading price and volume of the combined company common stock may be volatile following the mergers.

The trading price and volume of the combined company common stock may be volatile following completion of the mergers. The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of the combined company common stock. As a result, you may suffer a loss on your investment. Many factors may impair the market for the combined company common stock and the ability of investors to sell shares at an attractive price and could also cause the market price and demand for the combined company common stock to fluctuate substantially, which may negatively affect the price and liquidity of the combined company common stock. Many of these factors and conditions are beyond the control of the combined company or the combined company stockholders.

Following the consummation of mergers, the market price of the combined company common stock may be depressed by the perception that former MRC Global stockholders may sell the shares of common stock they will acquire at closing and for other reasons related to the mergers.

Subject to applicable securities laws, former MRC Global stockholders may seek to sell shares of the combined company common stock held by them on the Effective Time, following the consummation of the mergers. The transaction documents contain no restriction on the ability of former MRC Global stockholders to sell such shares of the combined company common stock. These sales (or the perception that these sales may occur), coupled with the increase in the outstanding number of shares of the combined company common stock, may affect the market for, and the market price of, shares of the combined company common stock in an adverse manner.

The unaudited pro forma combined financial statements and the unaudited prospective financial and operating information prepared by DNOW and MRC Global included in this joint proxy statement/prospectus are based on a number of preliminary estimates and assumptions and the actual results of operations, cash flows and financial position of the combined company after the mergers may differ materially.

The unaudited pro forma information and the unaudited prospective financial information in this joint proxy statement/prospectus is presented for illustrative purposes only, has been prepared based on available information and certain assumptions and estimates that DNOW and MRC Global believe are reasonable, and is not necessarily indicative of what DNOW’s actual financial position or results of operations would have been had the pro forma events been completed on the dates indicated. Further, the combined company’s actual results and financial position after the pro forma events occur may differ materially and adversely from the unaudited pro forma information included in this joint proxy statement/prospectus. The unaudited pro forma combined financial statements have been prepared with DNOW as the accounting acquirer under GAAP and reflect adjustments based upon preliminary estimates of the fair value of assets to be acquired and liabilities to be assumed.

The unaudited prospective financial information for DNOW and MRC Global included in this joint proxy statement/prospectus are based on various assumptions that may not be realized and may not prove to be reflective of actual future results.

The internal unaudited prospective financial information included under the sections “The Mergers — Certain Unaudited Prospective Financial and Operating Information” were based on assumptions of, and information available to, DNOW management and MRC Global management, as applicable, when prepared, and these estimates and assumptions are subject to uncertainties, many of which are beyond DNOW’s and MRC Global’s control and may not be realized. Many factors mentioned in this joint proxy statement/prospectus, including the risks outlined in this “Risk Factors” section and the events or circumstances described under “Cautionary Statement Regarding Forward-Looking Statements,” will be important in determining the combined company’s future results. As a result of these contingencies, actual future results may vary materially from DNOW’s and MRC Global’s estimates. In view of these uncertainties, the inclusion of the unaudited prospective financial information of DNOW and MRC Global in this joint proxy statement/prospectus is not and should not be viewed as a representation that the forecasted results will necessarily reflect actual future results.

DNOW’s and MRC Global’s unaudited prospective financial information was not prepared with a view toward public disclosure, and such unaudited prospective financial information was not prepared with a view toward compliance with published guidelines of any regulatory or professional body for the preparation or presentation of prospective financial information. Further, any forward-looking statement speaks only as of the date on which it is made, and neither DNOW nor MRC Global undertakes any obligation, other than as required by applicable law, to update the financial estimates herein to reflect events or circumstances after the date those financial estimates were prepared or to reflect the occurrence of anticipated or unanticipated events or circumstances.

The unaudited prospective financial information of DNOW and MRC Global included in this joint proxy statement/prospectus has been prepared by, and is the responsibility of, DNOW and MRC Global, as applicable. Moreover, neither DNOW’s nor MRC Global’s independent accountants, nor any other independent accountants, have compiled, examined or performed any procedures with respect to DNOW’s or MRC Global’s prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or achievability thereof, and, accordingly, such independent accountants assume no responsibility for, and disclaim any association with, DNOW’s and MRC Global’s prospective financial information.

The opinions of DNOW’s and MRC Global’s respective financial advisors will not reflect changes in circumstances between the signing of the merger agreement and the completion of the mergers.

Each of the boards of DNOW and MRC Global has received an opinion from its respective financial advisor in connection with the signing of the merger agreement, but has not obtained any updated opinion from its respective financial advisor as of the date of this joint proxy statement/prospectus. Changes in the operations and prospects of DNOW or MRC Global, general market and economic conditions and other factors that may be beyond the control of DNOW or MRC Global, and on which the companies’ respective financial advisors’ opinions were based, may significantly alter the value of DNOW or MRC Global or the prices of the shares of DNOW common stock or MRC Global common stock by the time the mergers are completed. The opinions do not speak as of the time the mergers will be completed or as of any date other than the date of such opinions. Because neither DNOW nor MRC Global currently anticipates asking its respective financial advisor to update its opinion, such opinions will not address the fairness of the mergers consideration from a financial point of view at the time the mergers are completed. The DNOW board’s recommendation that DNOW stockholders vote in favor of the DNOW stock issuance proposal and the MRC Global board’s recommendation that MRC Global stockholders vote in favor of the MRC Global merger proposal and the MRC Global compensation advisory proposal, however, are made as of the date of this joint proxy statement/prospectus.

The synergies attributable to the mergers may vary from expectations.

The combined company may fail to realize the anticipated benefits and synergies expected from the mergers, which could adversely affect the combined company’s business, financial condition and results of operations. The success of the mergers will depend, in significant part, on the combined company’s ability to successfully integrate the acquired business, grow the revenue of the combined company and realize the anticipated strategic benefits and synergies from the combination. DNOW and MRC Global believe that the combination of the companies will provide operational and financial scale, increasing free cash flow, and enhancing the combined company’s corporate rate of return. However, achieving these goals requires, among other things, realization of the targeted cost synergies expected from the mergers. This growth and the anticipated benefits of the transaction may not be realized fully or at all, or may take longer to realize than expected. Actual operating, technological, strategic and revenue opportunities, if achieved at all, may be less significant than expected or may take longer to achieve than anticipated. If the combined company is not able to achieve these objectives and realize the anticipated benefits and synergies expected from the mergers within the anticipated timing or at all, the combined company’s business, financial condition and results of operations may be adversely affected.

The future results of the combined company following the mergers will suffer if the combined company does not effectively manage its expanded operations.

Following the mergers, the size of the business of the combined company will increase significantly. The combined company’s future success will depend, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. The combined company may also face increased scrutiny from governmental authorities as a result of the significant increase in the size of its business. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from the mergers.

The mergers may result in a loss of customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners and may result in the termination of existing contracts.

Following the mergers, some of the customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners of DNOW or MRC Global may terminate or scale back their current or prospective business relationships with the combined company. Some customers may not wish to source a larger

40

##### Table of Contents

percentage of their needs from a single company or may feel that the combined company is too closely allied with one of their competitors. In addition, DNOW and MRC Global have contracts with customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners that may require DNOW or MRC Global to obtain consents from these other parties in connection with the mergers, which may not be obtained on favorable terms or at all. If relationships with customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners are adversely affected by the mergers, or if the combined company, following the mergers, loses the benefits of the contracts of DNOW or MRC Global, the combined company’s business and financial performance could suffer.

The DNOW bylaws designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by DNOW stockholders, which could limit DNOW stockholders’ ability to obtain a favorable judicial forum for disputes with DNOW or its directors, officers or other employees.

The DNOW bylaws provide that, unless the DNOW board otherwise determines, the Court of Chancery of the State of Delaware (or, in the event that such Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of DNOW, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director or officer of DNOW to DNOW or DNOW’s stockholders, creditors or other constituents, (iii) any action asserting a claim against DNOW or any director or officer of DNOW arising pursuant to any provision of the DGCL or the DNOW certificate of incorporation or the DNOW bylaws (as either may be amended from time to time), or (iv) any action asserting a claim against DNOW or any director or officer of DNOW governed by the internal affairs doctrine.

This provision would not apply to claims brought to enforce a duty or liability created by the Exchange Act, the Securities Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of DNOW is deemed to have received notice of and consented to the foregoing forum selection provision. This provision may limit DNOW stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with DNOW or its directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, DNOW may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect its business, financial condition and results of operations.

The combined company’s ability to use the existing U.S. federal capital loss carryforwards, net operating loss carryforwards and other tax attributes could be limited.

MRC Global had approximately $111 million of U.S. federal capital loss (“CL”) carryforwards (among other U.S. tax attributes) as of December 31, 2024, which will expire in 2029. In addition, DNOW had approximately $162 million of U.S. federal net operating loss (“NOL”) carryforwards (among other U.S. tax attributes) as of December 31, 2024, of which $15 million will expire in 2037 and $147 million have no expiration date. The combined company’s ability to utilize such U.S. federal NOL carryforwards, CL carryforwards and certain other U.S. tax attributes to reduce future income subject to U.S. federal income tax may be subject to certain limitations, including under Sections 382 and 383 of the Code in the event of an “ownership change” within the meaning of the Code.

41

##### Table of Contents

As a result of the mergers, MRC Global is expected to undergo such an ownership change. Accordingly, the utilization of MRC Global’s U.S. federal CL carryforwards is expected to be subject to an annual limitation under the Code. However, the impact of such limitation is not expected to be material since MRC Global believed it was more likely than not that the U.S. federal CL carryforwards would not have been realized by MRC Global (on a standalone basis) in any event. In addition, while DNOW is not expected to undergo an ownership change as a result of the mergers, such mergers could contribute to an ownership change now or in the future. However, based on current expectations, any limitation that may be imposed as a result of an ownership change is not expected to have a material impact on the combined company’s ability to utilize DNOW’s U.S. federal NOL carryforwards.

The combined company’s future credit facility has not been obtained and may not be obtained on acceptable or favorable terms to the combined company, or at all.

DNOW expects to obtain a new or extended senior secured revolving credit facility (the “Expanded ABL”) with aggregate commitments reflective of the borrowing base supported by DNOW and MRC Global assets, which would refinance and replace DNOW’s existing senior secured revolving credit facility. The terms and conditions of such Expanded ABL are uncertain and subject to negotiation, and commitments in respect thereof have not yet been obtained. If the Expanded ABL is not obtained for any reason, the combined company would need to rely on the DNOW ABL, which presently matures on December 14, 2026. The terms of the Expanded ABL or any other available financing may place limits on the combined company’s financial and operating flexibility. If adequate funds are not available on acceptable terms, the combined company may be forced to reduce its operations or delay, limit or abandon expansion opportunities. Moreover, even if the combined company is able to continue its operations, the failure to obtain the Expanded ABL or any other available financing could reduce its competitiveness.

Other Risks Relating to DNOW and MRC Global

As a result of entering into the merger agreement, DNOW’s and MRC Global’s businesses are and will be subject to the risks described above. In addition, DNOW and MRC Global are, and following completion of the mergers, DNOW will be, subject to the risks described in DNOW’s and MRC Global’s most recent Annual Report on Form 10-K as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus.

The DNOW board has fixed the close of business on , 2025 as the DNOW record date for the determination of the DNOW stockholders entitled to receive notice of, and to vote at, the DNOW special meeting. The DNOW stockholders of record on the DNOW record date are the only DNOW stockholders that are entitled to receive notice of, and to vote at, the DNOW special meeting or any adjournments or postponements of the DNOW special meeting.

Outstanding Shares as of Record Date and Voting Rights of DNOW Stockholders

On the DNOW record date, there were shares of DNOW common stock issued and outstanding, held by holders of record. Each share of DNOW common stock entitles its holder of record to one vote at the DNOW special meeting.

A complete list of registered DNOW stockholders entitled to vote at the DNOW special meeting will be available for viewing, for purposes germane to the DNOW special meeting, during ordinary business hours for a period of ten days before the DNOW special meeting at DNOW offices at 7402 North Eldridge Parkway, Houston, Texas 77041, and during the DNOW special meeting. Stockholders who wish to view such list in advance of the DNOW special meeting should contact the General Counsel by writing to DNOW Inc., Attn: General Counsel, 7402 North Eldridge Parkway, Houston, Texas 77041 or by calling (281) 823-4700.

Quorum; Abstentions and Broker Non-Votes

For business to be conducted at the DNOW special meeting, a quorum must be present. A quorum at the DNOW special meeting requires the presence, in person or by proxy, of the holders of a majority of the stock issued and outstanding and entitled to vote in the election of directors. If you submit a properly executed proxy card, even if you do not vote for the proposal or vote to “abstain” in respect of the proposal, your shares of DNOW common stock will be counted for purposes of calculating whether a quorum is present for the transaction of business at the DNOW special meeting. Abstentions (and broker non-votes, if any) are counted in determining that a quorum is present for the DNOW special meeting.

An abstention occurs when a stockholder attends a meeting, either in person or by proxy, but abstains from voting. At the DNOW special meeting, abstentions will be counted as present for purposes of determining whether a quorum exists. Assuming a quorum is present, abstaining from voting will have the same effect as a vote AGAINST the DNOW share issuance proposal and the DNOW adjournment proposal.

A so-called “broker non-vote” results when banks, brokers and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have

##### Table of Contents

not received specific voting instructions from the beneficial owner of such shares. DNOW does not expect any broker non-votes at the DNOW special meeting because the rules applicable to brokers, banks and other nominees only provide them with discretionary authority to vote on proposals that are considered routine, whereas each of the proposals to be presented at the DNOW special meeting are considered non-routine. As a result, no broker will be permitted to vote your shares at the DNOW special meeting without receiving instructions. Failure to instruct your broker, bank or other nominee on how to vote your shares will have no effect on the outcome of the proposals to be considered at the DNOW special meeting and such shares will not be counted as present in person or by proxy at the DNOW special meeting for purposes of determining a quorum.

Adjournment

Under the merger agreement, DNOW (i) is required to adjourn or postpone the DNOW special meeting to the extent necessary, based on good faith consultation with outside legal counsel, to ensure that any legally required supplement or amendment to this joint proxy statement/prospectus is provided to the DNOW stockholders or if, as of the time the DNOW special meeting is scheduled, there are insufficient shares of DNOW common stock represented (either in person or by proxy) to constitute a quorum necessary to conduct business at the DNOW special meeting, and (ii) may adjourn or postpone the DNOW special meeting if, as of the time for which the DNOW special meeting is scheduled, there are insufficient shares of DNOW common stock represented (either in person or by proxy) to obtain the approval of the DNOW stock issuance proposal; provided that the DNOW special meeting may not be adjourned or postponed to a date on or after two business days prior to the outside date; provided, further, that the DNOW special meeting shall not be postponed or adjourned as a result of item (ii) above for a period of more than ten business days in the aggregate without the prior written consent of MRC Global. See the section entitled “The Merger Agreement — Efforts to Hold the DNOW Special Meeting and the MRC Global Special Meeting — DNOW Special Meeting.”

In accordance with Section 2(b) of the DNOW bylaws, the chairman of the meeting of stockholders may adjourn the meeting from time to time, regardless of the outcome of the DNOW adjournment proposal. At any subsequent reconvening of the DNOW special meeting at which a quorum shall be present or represented, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the DNOW special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Vote Required

The votes required for each proposal are as follows:

| • |  | Proposal 1 (DNOW stock issuance proposal). Approval of the DNOW stock issuance proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. Abstentions will have the same effect as a vote AGAINST the DNOW stock issuance proposal; and

| • |  | Proposal 2 (DNOW adjournment proposal). Approval of the DNOW adjournment proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. Abstentions will have the same effect as a vote AGAINST the DNOW adjournment proposal.

The mergers cannot be completed without the approval of the DNOW stock issuance proposal. The approval of the DNOW adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

An abstention occurs when the beneficial owner of shares, or a bank, broker or other nominee holding shares for a beneficial owner, is present or represented by proxy, and entitled to vote at the meeting, but such person refrains from voting as to a particular proposal by expressly marking the “abstain” box on the voting instruction form or ballot.

Mail. DNOW stockholders that received proxy cards by mail may vote by mail by completing, signing, dating and returning the proxy card in the pre-addressed, postage-paid envelope provided. If a DNOW stockholder votes by mail but the proxy card is returned unsigned, then such vote cannot be counted. If a DNOW stockholder votes by mail and the returned proxy card is signed, but there is no indication of how to vote, the proxy will be voted as recommended by the DNOW board. If mailed, completed and signed proxy cards must be received by , 2025.

Meeting. DNOW stockholders may attend and vote at the DNOW special meeting.

DNOW stockholders who hold their shares of DNOW common stock beneficially in “street name” and wish to submit a proxy must provide instructions to the bank, broker or other nominee that holds their shares of record as to how to vote their shares with respect to the DNOW stock issuance proposal and the DNOW adjournment proposal. DNOW stockholders who hold their shares of DNOW common stock beneficially and wish to vote at the DNOW special meeting in person must obtain proxies issued in their own names (known as a “legal proxy”).

Proxies and Revocation

DNOW stockholders may revoke a proxy before the voting polls are closed at the DNOW special meeting, by the following methods:

| • |  | voting at a later time by Internet or telephone until 11:59 p.m. (Eastern Time) on , 2025;

| • |  | voting in person at the DNOW special meeting;

| • |  | delivering to the DNOW Secretary a proxy with a later date or a written revocation of the most recent proxy; or

| • |  | giving notice to the inspector of elections at the DNOW special meeting.

DNOW stockholders that hold their shares in street name (for example, shares held in the name of a bank, broker or other holder of record) and vote by proxy may later revoke such proxy by informing the holder of record in accordance with that entity’s procedures.

Solicitation of Proxies

DNOW will bear all costs of solicitation related to the DNOW special meeting. In addition to sending and making available these materials, some of DNOW’s directors, officers and other employees may solicit proxies by contacting DNOW stockholders via the Internet, by mail, personal interview or telephone. None of DNOW’s officers or employees will receive any extra compensation for soliciting DNOW stockholders. DNOW may also request banking institutions, brokerage firms, custodians, nominees and fiduciaries to forward solicitation material to the beneficial owners of the DNOW common stock that those companies or persons hold of record, and DNOW will reimburse the forwarding expenses. In addition, DNOW has retained Okapi Partners to assist in soliciting proxies and has agreed to pay Okapi Partners a fee not to exceed $30,000 plus out of pocket expenses. DNOW will bear all costs of solicitation.

Dissenters’ or Appraisal Rights

Under the DGCL, DNOW stockholders are not entitled to dissenters’ or appraisal rights in connection with the DNOW stock issuance as contemplated by the merger agreement.

This process, known as “householding,” reduces the volume of duplicate information received at a household and helps to reduce DNOW’s expenses. A copy will also be sent upon written or oral request to any DNOW stockholder of a shared address to which a single copy was delivered. If two or more DNOW stockholders with a shared address are currently receiving only one copy, then they may request to receive multiple packages in the future, or if a DNOW stockholder is currently receiving multiple packages, then the DNOW stockholder may request to receive a single copy in the future. Such requests may be made by writing to Investor Relations, DNOW Inc., 7402 North Eldridge Parkway, Houston, Texas 77041 or by calling (281) 823-4700.

DNOW PROPOSAL 1 — DNOW STOCK ISSUANCE PROPOSAL

This joint proxy statement/prospectus is being furnished to you as a stockholder of DNOW as part of the solicitation of proxies by the DNOW board for use at the DNOW special meeting to consider and vote upon a proposal to approve the issuance of shares of DNOW common stock to holders of Eligible MRC Global shares in connection with the transactions pursuant to the terms of the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus. Under the rules of the NYSE, a company listed on the NYSE is required to obtain stockholder approval prior to the issuance of common stock in any transaction or series of related transactions if the number of shares of common stock to be issued is equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock. If the mergers are completed, DNOW expects to issue approximately      million shares of DNOW common stock in connection with the transactions, which will exceed 20% of the shares of DNOW common stock outstanding before such issuance, and for this reason, DNOW must obtain the approval of DNOW stockholders for the issuance of shares of DNOW common stock in connection with the transactions.

In the event the DNOW stock issuance proposal is approved by the DNOW stockholders, but the merger agreement is terminated (without the mergers being completed) prior to the issuance of shares of DNOW common stock pursuant to the merger agreement, DNOW will not issue any shares of DNOW common stock as a result of the approval of the DNOW stock issuance proposal.

The DNOW board has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the DNOW stock issuance, are fair to, and in the best interests of, DNOW and the DNOW stockholders and approved and declared advisable the merger agreement and the transactions contemplated by the merger agreement, including the DNOW stock issuance.

The DNOW board accordingly unanimously recommends that DNOW stockholders vote “FOR” the DNOW stock issuance proposal pursuant to the merger agreement, as disclosed in this joint proxy statement/prospectus, particularly the related narrative disclosures in “The Mergers” and “The Merger Agreement” and as attached as Annex A to this joint proxy statement/prospectus. The merger cannot be completed without the approval of the DNOW stock issuance proposal.

Assuming a quorum is present at the DNOW special meeting, approval of the DNOW stock issuance proposal requires the affirmative vote of a majority of the shares of DNOW common stock present in person or represented by proxy at the DNOW special meeting. Abstentions will have the same effect as a vote AGAINST the DNOW stock issuance proposal. We do not expect there to be broker-non votes.

IF YOU ARE A DNOW STOCKHOLDER,

THE DNOW BOARD UNANIMOUSLY RECOMMENDS

THAT YOU VOTE “FOR” THE DNOW STOCK ISSUANCE PROPOSAL

DNOW PROPOSAL 2 — DNOW ADJOURNMENT PROPOSAL

Abstentions will have the same effect as a vote AGAINST the DNOW adjournment proposal. We do not expect there to be broker-non votes.

MRC GLOBAL SPECIAL MEETING

General

This joint proxy statement/prospectus is being provided to MRC Global stockholders as part of a solicitation of proxies by the MRC Global board for use at the MRC Global special meeting and at any adjournments or postponements of such special meeting. This joint proxy statement/prospectus provides MRC Global stockholders with important information about the MRC Global special meeting and should be read carefully in its entirety.

Date, Time and Place of the MRC Global Special Meeting

The MRC Global special meeting will be held on     , 2025 at  : a.m., Central Time, at the offices of MRC Global located at 1301 McKinney Street, Suite 2300, Houston, Texas 77010.

Purpose of the MRC Global Special Meeting

The MRC Global special meeting is being held to consider and vote on the following proposals:

| • |  | Proposal 1 (MRC Global merger proposal): to adopt and approve the merger agreement, by and among MRC Global, DNOW, Merger Sub and LLC Sub, the mergers and the other transactions contemplated thereby, pursuant to which (i) MRC Global will merge with and into Merger Sub, with MRC Global continuing its existence as the surviving corporation following the First Merger as a direct, wholly-owned subsidiary of DNOW, and (ii) immediately following the First Merger, the surviving corporation will merge with and into LLC Sub, with LLC Sub surviving the Second Merger as a direct, wholly-owned subsidiary of DNOW;

| • |  | Proposal 2 (MRC Global compensation advisory proposal): to approve, on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s NEOs that is based on or otherwise relates to the mergers; and

| • |  | Proposal 3 (MRC Global adjournment proposal): to approve the adjournment of the MRC Global special meeting to solicit additional proxies if there are not sufficient votes at the time of the MRC Global special meeting to approve the MRC Global merger proposal.

For the avoidance of doubt, neither the approval of the MRC Global compensation advisory proposal nor the approval of the MRC Global adjournment proposal is a condition to the closing of the mergers or otherwise required to effectuate the mergers.

Recommendation of the MRC Global Board

The MRC Global board unanimously recommends that MRC Global stockholders vote:

| • |  | Proposal 1 (MRC Global merger proposal): “FOR”;

| • |  | Proposal 2 (MRC Global compensation advisory proposal): “FOR”; and

| • |  | Proposal 3 (MRC Global adjournment proposal): “FOR.”

This joint proxy statement/prospectus contains important information regarding these proposals and factors that MRC Global stockholders should consider when deciding how to cast their votes. MRC Global stockholders are encouraged to read this entire document carefully, including the annexes attached to and documents incorporated by reference into this joint proxy statement/prospectus, for more detailed information regarding the merger agreement and the transactions contemplated thereby, including the MRC Global merger proposal, the MRC Global compensation advisory proposal and the MRC Global adjournment proposal.

The Non-Binding MRC Global Compensation Advisory Proposal and Interests of Directors

In considering the recommendations of the MRC Global board, MRC Global stockholders should be aware that certain of MRC Global’s directors and executive officers may have interests that are different from, or in addition to, the interests of MRC Global stockholders more generally. For additional information, please see “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers.”

Section 14A of the Exchange Act requires that MRC Global provide its stockholders with the opportunity to vote to approve, on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s NEOs that is based on or otherwise relates to the mergers, as disclosed in this joint proxy statement/prospectus, including the compensation table and the related narrative NEO compensation disclosures set forth in “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers.” This vote is commonly referred to as a “say on golden parachute” vote. Accordingly, MRC Global stockholders are being provided with the opportunity to cast an advisory (non-binding) vote on those change of control payments.

MRC Global stockholders should note that the MRC Global compensation advisory proposal is merely an advisory vote that will not be binding on MRC Global, DNOW or their respective boards of directors. Further, the underlying plans and arrangements are contractual in nature and not, by their terms, subject to stockholder approval. Accordingly, regardless of the outcome of the vote on the MRC Global compensation advisory proposal, if the mergers are consummated, the eligibility of the MRC Global NEOs for such payments and benefits will not be affected by the outcome of the advisory vote.

The MRC Global compensation advisory proposal is a proposal separate and apart from the MRC Global merger proposal. Accordingly, an MRC Global stockholder may vote to approve one proposal and not the other. Because the vote on the MRC Global compensation advisory proposal is on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s NEOs that is based on or otherwise relates to the mergers is advisory in nature only, it will not be binding on MRC Global or DNOW, and the approval of the MRC Global compensation advisory proposal is not a condition to the completion of the mergers or otherwise required to effectuate the mergers.

Voting by Directors and Executive Officers

On the MRC Global record date, there were      shares of MRC Global common stock issued and outstanding, held by     holders of record. On the MRC Global record date, MRC Global directors and executive officers, and their affiliates, as a group, beneficially owned and were entitled to vote     shares of MRC Global common stock, or approximately      % of the issued and outstanding shares of MRC Global common stock. Although none of them have entered into any agreement obligating them to do so as a director or executive officer of MRC Global, MRC Global currently expects that all of its directors and executive officers will vote their shares “FOR” the MRC Global merger proposal, “FOR” the MRC Global compensation advisory proposal and “FOR” the MRC Global adjournment proposal.

Attendance at the MRC Global Special Meeting

Only MRC Global stockholders of record on the MRC Global record date, beneficial owners of MRC Global common stock on the MRC Global record date, holders of valid proxies for the MRC Global special meeting and invited guests of MRC Global may attend the MRC Global special meeting, which will be held at the offices of MRC Global, located at 1301 McKinney Street, Suite 2300, Houston, Texas 77010.

MRC Global stockholders will be able to attend, vote their shares, and submit questions during the MRC Global special meeting. The MRC Global special meeting will begin promptly at   :   a.m., Central Time.

Record Date

The MRC Global board has fixed the close of business on     , 2025 as the MRC Global record date for the determination of the MRC Global stockholders entitled to receive notice of, and to vote at, the MRC

Global special meeting. The MRC Global stockholders of record on the MRC Global record date are the only MRC Global stockholders that are entitled to receive notice of, and to vote at, the MRC Global special meeting or any adjournments or postponements of the MRC Global special meeting.

Outstanding Shares as of Record Date and Voting Rights of MRC Global Stockholders

On the MRC Global record date, there were     shares of MRC Global common stock issued and outstanding, held by      holders of record. Each share of MRC Global common stock entitles its holder of record to one vote at the MRC Global special meeting.

A complete list of registered MRC Global stockholders entitled to vote at the MRC Global special meeting will be available for viewing, for purposes germane to the MRC Global special meeting, during ordinary business hours for a period of ten days prior to the MRC Global special meeting at the offices of MRC Global, located at 1301 McKinney Street, Suite 2300, Houston, Texas 77010. MRC Global stockholders who wish to view such list in advance of the MRC Global special meeting should contact MRC Global in writing at MRC Global Inc., Attn: Corporate Secretary, 1301 McKinney Street, Suite 2300, Houston, Texas 77010.

Quorum; Abstentions and Broker Non-Votes

For business to be conducted at the MRC Global special meeting, a quorum must be present. A quorum at the MRC Global special meeting constitutes the holders of not less than a majority of the voting power of all the shares entitled to vote at the MRC Global special meeting, present in person or by proxy. If you submit a properly executed proxy card, even if you do not vote for the proposals or vote to “abstain” in respect of the proposals, your shares of MRC Global common stock will be counted for purposes of calculating whether a quorum is present for the transaction of business at the MRC Global special meeting. Abstentions are counted in determining that a quorum is present for the MRC Global special meeting.

An abstention occurs when a stockholder attends a meeting, either in person or by proxy, but abstains from voting. At the MRC Global special meeting, abstentions will be counted as present for purposes of determining whether a quorum exists. Assuming a quorum is present, abstaining from voting will have the same effect as a vote AGAINST the MRC Global merger proposal and will have no effect on the outcome of the MRC Global compensation advisory proposal and the MRC Global adjournment proposal.

A so-called “broker non-vote” results when banks, brokers and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares. MRC Global does not expect any broker non-votes at the MRC Global special meeting because the rules applicable to brokers, banks and other nominees only provide them with discretionary authority to vote on proposals that are considered routine, whereas each of the proposals to be presented at the MRC Global special meeting are considered non-routine. As a result, no broker will be permitted to vote your shares at the MRC Global special meeting without receiving instructions. Failure to instruct your broker, bank or other nominee on how to vote your shares will have no effect on the outcome of the proposals to be considered at the MRC Global special meeting and such shares will not be counted as present in person or by proxy at the MRC Global special meeting for purposes of determining a quorum.

Adjournment

Under the merger agreement, MRC Global (i) is required to adjourn or postpone the MRC Global special meeting to the extent necessary, based on good faith consultation with outside legal counsel, to ensure that any legally required supplement or amendment to this joint proxy statement/prospectus is provided to the MRC Global stockholders or if, as of the time for which the MRC Global special meeting is scheduled, there are insufficient shares of MRC Global common stock represented (either in person or by proxy) to constitute a

See the section entitled “The Merger Agreement — Efforts to Hold the DNOW Special Meeting and the MRC Global Special Meeting — MRC Global Special Meeting.”

In accordance with Article II, Section 8 of the MRC Global bylaws, the chairman of the MRC Global special meeting may adjourn the MRC Global special meeting to another place, if any, date and time, regardless of the outcome of the MRC Global adjournment proposal. At any subsequent reconvening of the MRC Global special meeting at which a quorum shall be present or represented, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the MRC Global special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Vote Required

The votes required for each proposal are as follows:

| • |  | Proposal 1 (MRC Global merger proposal). Approval of the MRC Global merger proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on such proposal. The mergers cannot be completed without the approval of the MRC Global merger proposal.

| • |  | Proposal 2 (MRC Global compensation advisory proposal). Approval of the MRC Global compensation advisory proposal, on a non-binding advisory basis, requires the affirmative vote of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. For the avoidance of doubt, the approval of MRC Global compensation advisory proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

| • |  | Proposal 3 (MRC Global adjournment proposal). Approval of the MRC Global adjournment proposal requires the affirmative vote of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. For the avoidance of doubt, the approval of the MRC Global adjournment proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

An abstention occurs when the beneficial owner of shares, or a bank, broker or other nominee holding shares for a beneficial owner, is present or represented by proxy, and entitled to vote at the meeting, but such person refrains from voting as to a particular proposal by expressly marking the “abstain” box on the voting instruction form or ballot.

A so-called “broker non-vote” results when banks, brokers and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares. MRC Global does not expect any broker non-votes at the MRC Global special meeting because the rules applicable to brokers, banks and other nominees only provide them with discretionary authority to vote on proposals that are considered routine, whereas each of the proposals to be presented at the MRC Global special meeting are considered non-routine. As a result, no broker will be permitted to vote your shares at the MRC Global special meeting without receiving instructions. Failure to instruct your broker, bank or other nominee on how to vote your shares will have no effect on the outcome of the proposals to be considered at the MRC Global special meeting and such shares will not be counted as present in person or by proxy at the MRC Global special meeting for purposes of determining a quorum.

Householding of MRC Global Special Meeting Materials

One copy of this joint proxy statement/prospectus and notice will be sent to MRC Global stockholders that share an address, unless they have notified MRC Global that they want to continue receiving multiple packages.

Each MRC Global stockholder in the household will continue to receive a separate proxy card. This process, known as “householding,” reduces the volume of duplicate information received at a household and helps to reduce MRC Global’s expenses. A copy will also be sent upon written or oral request to any MRC Global stockholder of a shared address to which a single copy was delivered. If two or more MRC Global stockholders with a shared address are currently receiving only one copy, then they may request to receive multiple packages in the future, or if an MRC Global stockholder is currently receiving multiple packages, then the MRC Global stockholder may request to receive a single copy in the future. Such requests may be made by writing to MRC Global Inc., Attn: Corporate Secretary, 1301 McKinney Street, Suite 2300, Houston, Texas 77010 or by calling (877) 294-7574. If two or more MRC Global stockholders object to householding and wish to receive multiple packages in the future, or if such stockholders received multiple packages at a single address and would like to request delivery of a single copy in the future, such stockholder may contact MRC Global’s Corporate Secretary as described above if he/she is a holder of record. If such MRC Global stockholder holds their shares through a bank, broker or other holder of record, he/she should contact such holder of record.

MRC Global stockholders may contact MRC Global’s proxy solicitor with any questions about the MRC Global merger proposal, the MRC Global compensation advisory proposal, the MRC Global adjournment proposal or how to vote or to request additional copies of any materials at:

MRC GLOBAL PROPOSAL 1 — MRC GLOBAL MERGER PROPOSAL

The MRC Global board, after due and careful discussion and consideration, unanimously approved and recommended that MRC Global stockholders approve and adopt the merger agreement, the execution, delivery and performance of the merger agreement and the consummation of the mergers contemplated thereby.

The MRC Global board accordingly unanimously recommends that MRC Global stockholders vote “FOR” the MRC Global merger proposal, as disclosed in this joint proxy statement/prospectus, particularly the related narrative disclosures in the sections of this joint proxy statement/prospectus entitled “The Mergers” and “The Merger Agreement,” and as attached as Annex A to this joint proxy statement/prospectus.

The mergers cannot be completed without the affirmative vote of the holders of a majority of the issued and outstanding shares of MRC Global common stock entitled to vote on the MRC Global merger proposal. Accordingly, an MRC Global stockholder’s abstention from voting, the failure of an MRC Global stockholder to vote or the failure of an MRC Global stockholder to submit a proxy will have the same effect as a vote AGAINST the MRC Global merger proposal.

IF YOU ARE AN MRC GLOBAL STOCKHOLDER,

THE MRC GLOBAL BOARD UNANIMOUSLY RECOMMENDS

THAT YOU VOTE “FOR” THE MRC GLOBAL MERGER PROPOSAL

MRC GLOBAL PROPOSAL 2 — MRC GLOBAL COMPENSATION ADVISORY PROPOSAL

Pursuant to Section 14A of the Exchange Act and Rule 14a-21(c) thereunder, MRC Global is seeking a non-binding advisory stockholder approval of the compensation of MRC Global’s NEOs that is based on or otherwise relates to the mergers as disclosed in “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers — Quantification of Potential Payments and Benefits to MRC Global’s Named Executive Officers in Connection with the Mergers.” The proposal gives MRC Global stockholders the opportunity to express their views on the compensation of MRC Global’s NEOs.

Accordingly, the MRC Global board unanimously recommends that MRC Global stockholders vote “FOR” the adoption of the following resolution, on a non-binding advisory basis:

“RESOLVED, that MRC Global stockholders approve, on a non-binding advisory basis, the compensation that may be paid or become payable to MRC Global’s NEOs that is based on or otherwise relates to the mergers, as disclosed pursuant to Item 402(t) of Regulation S-K under the heading “The Mergers — Interests of Certain MRC Global Directors and Executive Officers in the Mergers — Quantification of Potential Payments and Benefits to MRC Global’s Named Executive Officers in Connection with the Mergers” (which disclosure includes the compensation table and related narrative NEO compensation disclosures required pursuant to Item 402(t) of Regulation S-K).”

The vote on the MRC Global compensation advisory proposal, on a non-binding advisory basis, is a vote separate and apart from the vote on the MRC Global merger proposal. Accordingly, MRC Global stockholders may vote to approve the MRC Global merger proposal and vote not to approve the MRC Global compensation advisory proposal, and vice versa. If the mergers are completed, the compensation may be paid to MRC Global’s NEOs to the extent payable in accordance with the terms of the compensation agreements and arrangements even if the MRC Global stockholders fail to approve the MRC Global compensation advisory proposal. For the avoidance of doubt, the approval of the MRC Global compensation advisory proposal is not a condition to the closing of the mergers or otherwise required to effectuate the mergers.

Approval of the MRC Global compensation advisory proposal, on a non-binding advisory, basis requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting, provided that a quorum is present. An MRC Global stockholder’s abstention from voting or the failure of an MRC Global stockholder to vote will have no effect on the outcome of the MRC Global compensation advisory proposal.

Assuming a quorum is present at the MRC Global special meeting, approval of the MRC Global adjournment proposal requires the affirmative vote of the holders of a majority of the votes cast by MRC Global stockholders present in person or represented by proxy at the MRC Global special meeting. Accordingly, an MRC Global stockholder’s abstention from voting or failure to vote will have no effect on the MRC Global adjournment proposal.

Background of the Mergers

The terms of the merger agreement are the result of arm’s-length negotiations between representatives of DNOW and MRC Global. The following is a summary of the material events leading up to the signing of the merger agreement and the key meetings, negotiations and discussions among DNOW and MRC Global and their respective advisors that preceded the public announcement of the transaction. However, this summary does not purport to catalogue every conversation or interaction among them.

In the ordinary course of business and consistent with their respective fiduciary duties, the board of directors of each of DNOW and MRC Global, along with their respective management teams, regularly review the operating results, capital structures, future growth opportunities and competitive positions of their respective companies. These reviews have included consideration by the companies’ respective management teams and boards of directors and, from time to time, discussions with outside financial and legal advisors and other industry participants of potential strategic transactions, including acquisitions and divestitures, joint ventures, business combinations and other transactions, as well as ongoing initiatives aimed at enhancing stockholder value, strengthening their respective financial and liquidity positions, increasing their respective cash flows and growing their respective businesses organically, to prepare for and respond to changing market forces and resulting business risks and uncertainties in the industries in which they operate.

Since becoming a publicly traded company in 2014, DNOW has been focused on driving growth by allocating capital towards strategic channels, value-added product lines and related services. In furtherance of this strategy, DNOW has executed on the acquisition and integration of 24 transactions since 2014, with a focus on maintaining a strong balance sheet with a streamlined capital structure. At various times, DNOW’s general

63

##### Table of Contents

review and evaluation of potential strategic transactions included an assessment of MRC Global’s businesses and operations.

MRC Global, which in 2015 issued $363 million of 6.50% Series A convertible perpetual preferred stock (the “MRC Global Series A Preferred Stock”), selectively has considered benefits and risks to a variety of transactional opportunities, including large scale mergers and acquisitions, over the past 10 years. In connection with its periodic review of transactional opportunities, MRC Global reviewed certain of DNOW’s publicly available information, became familiar with its financial performance and condition, management team and businesses and considered potential synergies and other merits and demerits of a potential transaction with DNOW.

In September 2023 and in connection with MRC Global’s consideration of mergers and acquisitions, generally, MRC Global engaged J.P. Morgan as a financial advisor, formalized pursuant to an engagement letter reflecting this engagement dated November 7, 2023 (the “J.P. Morgan engagement letter”), and then subsequently terminated the J.P. Morgan engagement letter pursuant to a termination notice dated July 12, 2024.

From time to time, the chief executive officers of DNOW and MRC Global met and communicated informally at industry events and elsewhere regarding industry trends and the performance, business, strategic direction and prospects of their respective companies, including general discussions of a potential transaction between the two companies. Prior to the discussions described below, none of these informal communications involved the negotiation of any specific terms of a potential transaction between DNOW and MRC Global. The parties did not enter into any confidentiality agreements to further any discussions or negotiations before the discussions described below.

On October 14, 2024 and in furtherance of its strategic efforts to enhance stockholder value and simplify its capital structure, MRC Global entered into a definitive agreement to repurchase all of the issued and outstanding shares of the MRC Global Series A Preferred Stock.

On October 21, 2024, Robert Saltiel, the chief executive officer of MRC Global, contacted David Cherechinsky, the chief executive officer of DNOW, and they scheduled an in-person meeting.

On October 24, 2024, Messrs. Saltiel and Cherechinsky met in person. At the meeting, Mr. Saltiel expressed an interest in exploring a potential business combination between DNOW and MRC Global, citing his belief that the business combination would present substantial benefits to all stakeholders due to increased scale, diversified product offerings and synergies. Mr. Cherechinsky noted that DNOW favorably viewed both MRC Global’s repurchase of the MRC Global Series A Preferred Stock and its reduction of debt over the past several quarters and believed that there was industrial logic in a potential business combination between DNOW and MRC Global. Mr. Cherechinsky stated that the DNOW management team was focused on its earnings announcement scheduled for early November but that he would discuss the potential combination between the companies with the DNOW board. No specific details or terms of a transaction were discussed, and both of them agreed to keep communication channels open.

Following the meeting on October 24, 2024, Mr. Cherechinsky contacted Dick Alario, chairman of the DNOW board, to discuss the conversation between Messrs. Saltiel and Cherechinsky. Messrs. Cherechinsky and Alario discussed the process of briefing the full DNOW board on MRC Global’s approach regarding a potential business combination transaction.

On October 29, 2024, MRC Global consummated the repurchase of the MRC Global Series A Preferred Stock.

On October 30, 2024, MRC Global’s board held a board dinner in connection with its regularly scheduled meeting the next morning. At the dinner, Mr. Saltiel informed the MRC Global board of Mr. Saltiel’s October 24,

64

##### Table of Contents

2024 conversation with Mr. Cherechinsky. It was the consensus of the MRC Global board that MRC Global should further analyze a potential combination with DNOW.

On October 31, 2024, Mr. Cherechinsky provided an update to the DNOW board on the business, including two potential acquisition candidates and the potential business combination transaction that MRC Global suggested. After discussion, the DNOW board recommended that Mr. Cherechinsky meet with Mr. Saltiel again in the coming weeks to clarify MRC Global’s view of a potential transaction and directed the DNOW management team to engage professional advisors to facilitate the DNOW board’s consideration of a potential transaction with MRC Global.

On November 3, 2024, the MRC Global board met to discuss governance matters. As part of that meeting, with members of MRC Global’s senior management and a representative of Akin Gump Strauss Hauer & Feld LLP, MRC Global’s legal advisor (“Akin”), in attendance, the MRC Global board discussed a potential business combination transaction with DNOW. Mr. Saltiel summarized his October 24, 2024 meeting with Mr. Cherechinsky. Among other things, the MRC Global board discussed the terms of its prior engagement of J.P. Morgan and the representative of Akin provided privileged and confidential advice relating to fiduciary duties and process considerations if MRC Global were to pursue a strategic transaction with DNOW. It was the consensus of the MRC Global board that MRC Global should re-engage J.P. Morgan as its financial advisor in connection with MRC Global’s review of potential strategic opportunities, including a potential transaction with DNOW, on the basis of, among other factors, J.P. Morgan’s experience in the valuation of businesses and their securities in connection with mergers and acquisitions, its qualifications and reputation in connection with such matters and its familiarity with MRC Global, DNOW and the industries in which they operate.

On November 4, 2024, Robert L. Wood retired as chairman of MRC Global’s board, and Deborah G. Adams was appointed chair pursuant to action taken at the November 3, 2024 MRC Global board meeting.

On November 8, 2024, Mr. Saltiel contacted Mr. Cherechinsky to review their October 2024 discussion regarding a potential transaction. Mr. Cherechinsky responded that the topic would be considered at the next regularly scheduled meeting of the DNOW board, and that Mr. Cherechinsky would reach back out to Mr. Saltiel if DNOW desired to begin negotiations.

On November 15, 2024, Mr. Cherechinsky contacted Mr. Saltiel to set up a discussion for the following week.

On November 20, 2024, Messrs. Cherechinsky and Saltiel discussed their prior conversation in October 2024, including discussing several potential benefits of a combination of the two companies, such as increased scale, diversified product offerings and synergies. Both agreed to speak with their respective boards of directors about whether to explore a potential transaction between DNOW and MRC Global.

On November 26, 2024, pursuant to a unanimous written consent of the members of the board of MRC Global, the MRC Global board ratified the re-engagement of J.P. Morgan as its financial advisor pursuant to an amendment to the J.P. Morgan engagement letter dated as of November 25, 2024.

In November 2024, DNOW management determined to engage Kirkland & Ellis LLP (“Kirkland”) to serve as its outside legal advisor in connection with its evaluation of the proposed transaction with MRC Global. DNOW executed an engagement letter with Kirkland on December 9, 2024.

On December 2, 2024, DNOW engaged Goldman Sachs & Co. LLC (“Goldman Sachs”) as DNOW’s financial advisor due to, among other factors, Goldman Sachs’ qualifications, expertise and experience in M&A transactions.

On December 16, 2024, representatives of Goldman Sachs provided customary relationship disclosures to DNOW which included disclosure of certain relationships between Goldman Sachs and its representatives, on the

65

##### Table of Contents

one hand, and MRC Global and certain of its affiliates, on the other hand. The DNOW board later reviewed such disclosures from Goldman Sachs and determined that Goldman Sachs did not have any material relationships that would adversely affect its ability to act as financial advisor to DNOW.

On December 16, 2024, MRC Global announced the divestiture of its Canadian business and operations in a transaction that would allow MRC Global to focus on areas with greater profit potential and revenue growth, and to support its capital allocation priorities.

On December 17, 2024, the DNOW board met with members of DNOW management and representatives of each of Kirkland and Goldman Sachs. Mr. Cherechinsky provided an overview of a potential business combination transaction with MRC Global, including the pendency of MRC Global’s divestiture of its Canadian operations. The participants discussed the rationale for a potential combination, including enhanced diversification and synergies of the combined company. Representatives of Goldman Sachs reviewed Goldman Sachs’ preliminary financial analyses of a potential transaction based on publicly available information, and the DNOW board discussed a number of potential transaction structures, including a merger of equals or DNOW’s acquisition of MRC Global at various transaction premia. The DNOW board requested that Goldman Sachs update its preliminary financial analyses to reflect MRC Global’s recently announced divestiture of its Canadian operations for further consideration after the holidays. Additionally, the DNOW board expressed its support for exploring a potential no-premium transaction with MRC Global.

On January 7, 2025, Mr. Saltiel contacted Mr. Cherechinsky and, later that same day, the two discussed the potential transaction. Mr. Cherechinsky indicated that DNOW would be supportive of a stock for stock, no-premium transaction between DNOW and MRC Global, with the DNOW management team and DNOW board controlling the combined company.

On January 13, 2025, the MRC Global board met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Mr. Saltiel provided the MRC Global board with an update on his discussion on January 7, 2025 with Mr. Cherechinsky. Representatives of J.P. Morgan provided the MRC Global board with an overview of industry trends and a preliminary financial review with respect to the DNOW proposal, including percentage of premium to each of DNOW’s and MRC Global’s respective share prices and the implied exchange ratio. Representatives of Akin then provided the MRC Global board with privileged and confidential advice. Following discussion, the MRC Global board determined that it would be appropriate to establish a special committee, consisting of Ms. Adams, who would serve as the committee’s chairperson, Leonard Anthony, David Hager, Daniel B. Silvers and Mr. Saltiel (the “MRC Global project committee”).

On January 15, 2025, Mr. Saltiel contacted Mr. Cherechinsky to inform him that the MRC Global board had met to discuss DNOW’s view of any potential transaction between the parties and to request an in-person meeting to discuss.

On January 16, 2025, Messrs. Saltiel and Cherechinsky met in person in Houston, Texas. During that meeting, Mr. Saltiel previewed to Mr. Cherechinsky that the MRC Global board intends to prepare and send a non-binding summary of key terms relating to a proposed transaction that would include terms consistent with a “merger of equals,” including an even split of representation of directors on the combined company board and integration of management teams, together with a requested premium of approximately 10-15% to MRC Global stockholders. Messrs. Cherechinsky and Saltiel also discussed potential synergies and the need for both parties to conduct financial, operational and legal diligence.

On January 17, 2025, the MRC Global project committee met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Mr. Saltiel provided a report on his discussions with Mr. Cherechinsky on January 16, 2025. The MRC Global project committee then reviewed and discussed potential terms of a transaction, as well as certain preliminary financial analyses that J.P. Morgan had prepared and previously distributed to the committee. After discussion, the MRC Global project committee authorized and directed Mr. Saltiel to provide DNOW with a draft mutual non-disclosure agreement to be entered into by

66

##### Table of Contents

DNOW and MRC Global and a non-binding term sheet outlining MRC Global’s proposal for the key terms of a potential transaction with DNOW (the “MRC Global Term Sheet”).

On the same day, representatives of J.P. Morgan provided a customary relationship disclosure letter to the MRC Global board, which disclosed certain relationships between J.P. Morgan and its affiliates, on the one hand, and each of MRC Global, DNOW and certain other potential strategic counterparties, on the other hand. The MRC Global board later considered such disclosures provided by J.P. Morgan and determined that J.P. Morgan did not have any material relationships with DNOW that would adversely affect its ability to act as financial advisor to MRC Global.

Later the same day, Mr. Saltiel emailed Mr. Cherechinsky a draft mutual non-disclosure agreement and the MRC Global Term Sheet, which included terms that contemplated the following:

| • |  | DNOW acquiring MRC Global in an all-stock transaction at a 15% premium to the 30-day trailing volume weighted average price (“VWAP”) of MRC Global’s share price at that time;

| • |  | the chief executive officer of the combined company would be Mr. Cherechinsky;

| • |  | the chief financial officer would be Mr. Kelly Youngblood, chief financial officer of MRC Global;

| • |  | at least two unspecified members of MRC Global’s executive management team would continue with the combined company; and

| • |  | a “best athlete” approach would be used to determine the remaining executive management positions.

The MRC Global Term Sheet also noted, among other things, that MRC Global’s proposal was subject to the completion of due diligence, focusing on synergies, financial review and confirmatory due diligence, with a target signing date within 30 days from receipt of the letter. Later that same day, Mr. Cherechinsky contacted the DNOW board to provide an overview of the MRC Global Term Sheet.

On January 20, 2025, Mr. Cherechinsky and certain other members of DNOW’s management team met with Mr. Alario and representatives of each of Goldman Sachs and Kirkland to discuss the terms of the MRC Global Term Sheet.

On January 21, 2025, Messrs. Cherechinsky and Saltiel discussed via telephone the status and process with respect to a potential transaction, including the proposed terms in the MRC Global Term Sheet. Mr. Cherechinsky confirmed to Mr. Saltiel that, after having met the prior day with Mr. Alario, DNOW’s advisors and certain members of DNOW’s management team to discuss the MRC Global Term Sheet, there was continued interest by DNOW in exploring a potential business combination transaction, subject to alignment on the proposed premium and governance arrangements. Later that same day, Mr. Cherechinsky called Mr. Saltiel to express DNOW’s willingness to enter into a non-disclosure agreement to facilitate sharing and evaluation of confidential information between the parties.

On January 21, 2025, the MRC Global project committee met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Mr. Saltiel provided the MRC Global project committee with a report on his discussions with Mr. Cherechinsky earlier that same day. The MRC Global project committee authorized and directed Mr. Saltiel to request that DNOW provide a written response to the MRC Global Term Sheet.

On January 22, 2025, Mr. Saltiel called Mr. Cherechinsky to request that any proposals or counter proposals that DNOW would make be in writing rather than communicated verbally.

On January 23, 2025, by unanimous written consent of the MRC Global board, the MRC Global board approved a charter of the MRC Global project committee that, among other things, formalized and empowered the MRC Global project committee to review, assess and assist the MRC Global board in reviewing and assessing a potential transaction with DNOW, to consider and make recommendations to the MRC Global board with

67

##### Table of Contents

respect to such potential transaction, including any proposed agreements, terms and conditions, and to assist the MRC Global board with analyzing and evaluating any alternative transaction proposals.

On January 24, 2025, DNOW and MRC Global negotiated and executed a customary mutual non-disclosure agreement, which included customary non-disclosure and nonuse provisions, a non-solicitation provision that prohibits certain representatives of either party that were engaged in the discussions between them from soliciting service providers and key commercial counterparties for the duration of the non-solicitation period, and a standstill provision that falls away on customary terms prohibiting each party, for the duration of the standstill period, from offering to acquire or acquiring the other party and from taking certain other actions.

Between January 25, 2025 and March 18, 2025, at the direction of MRC Global’s management and DNOW’s management, respectively, representatives of J.P. Morgan and representatives of Goldman Sachs discussed the terms set forth in the MRC Global Term Sheet telephonically and via email. During these communications, at the direction of DNOW’s management, representatives of Goldman Sachs conveyed DNOW’s continued interest in exploring a potential business combination transaction with MRC Global, subject to alignment on the financial and governance considerations.

On February 5, 2025, MRC Global announced that it had postponed the release of its financial results related to the fourth quarter and full year 2024, which had previously been scheduled for February 11, 2025, to allow additional time to complete year-end audit procedures specifically related to inventory cycle counts.

On February 26, 2025, the DNOW board held a regularly scheduled meeting and, among other matters, received updates from representatives of each of Goldman Sachs and Kirkland regarding the status of the potential transaction with MRC Global, including a review of the MRC Global Term Sheet. Representatives of Goldman Sachs reviewed a summary of the contacts between the parties since the last meeting of the DNOW board on December 17, 2024, which representatives of each of Goldman Sachs and Kirkland had attended, and reviewed Goldman Sachs’ preliminary financial analyses of a potential transaction. Representatives of Kirkland discussed the potential implications of MRC Global’s announced postponement of its fourth quarter and full year 2024 financial results. After discussion, the DNOW board and the DNOW management team, with the assistance of Goldman Sachs and Kirkland, discussed potential responses to the MRC Global Term Sheet, including responding with a potential counter proposal that contemplated a premium within a comparable range to the premium that MRC Global proposed in the MRC Global Term Sheet and governance that would provide that the DNOW management team remain in place at the combined company, with the addition of two to three members of MRC Global’s management team to the management team of the combined company, and that two unspecified independent directors of the MRC Global board join the combined company board at closing. The DNOW board agreed not to take any further action, including refraining from providing a counter proposal, until after MRC Global announced its fourth quarter and full year 2024 financial results, and DNOW and its advisors had the opportunity to review and analyze such results.

On March 14, 2025, MRC Global announced its fourth quarter and full year 2024 financial results.

On March 18, 2025, Mr. Cherechinsky emailed Mr. Saltiel a letter outlining DNOW’s non-binding proposal for the key terms of a transaction with MRC Global (the “DNOW March 18 Letter”). The DNOW March 18 Letter contemplated DNOW acquiring MRC Global at an exchange ratio of 0.8954 shares of DNOW common stock per share of MRC Global common stock, which represented a premium of 15% to the closing price of MRC Global common stock as of March 17, 2025 and implied a 42.2% pro forma ownership by MRC Global stockholders of the combined company. The DNOW March 18 Letter further contemplated the following:

| • |  | the chief executive officer, the chief financial officer and the chairman of the board of DNOW would remain in their respective roles in the combined company;

On March 21, 2025, the MRC Global project committee met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Mr. Saltiel reviewed the terms of the DNOW March 18 Letter. Representatives of J.P. Morgan provided an overview of MRC Global’s financial performance, including MRC Global’s share price following MRC Global’s reporting of its 2024 earnings and the resulting impact on the exchange ratios that DNOW proposed in the DNOW March 18 Letter and that MRC Global proposed in the MRC Global Term Sheet. In addition, representatives of J.P. Morgan reviewed and discussed J.P. Morgan’s analysis of various share prices of MRC Global and DNOW as of March 19, 2025. The MRC Global project committee, together with management, J.P. Morgan and Akin, then discussed DNOW’s proposed exchange ratio, premium and the possible basis for DNOW’s anticipated synergies for the combined companies, as well as DNOW’s proposed post-closing management and board composition of the combined companies.

On March 22, 2025, at the direction of MRC Global’s management, representatives of J.P. Morgan called representatives of Goldman Sachs to convey that MRC Global requested more detailed financial information in connection with the analysis on estimated synergies.

On March 24, 2025, the MRC Global board met, with members of MRC Global management and representatives of each of Akin and J.P. Morgan in attendance. Among other things, the MRC Global board discussed the potential transaction with DNOW, including a review of the DNOW March 18 Letter. Representatives of J.P. Morgan apprised the MRC Global board of its discussions with representatives of Goldman Sachs, particularly with respect to potential synergies and requisite business and financial due diligence. The MRC Global board and the MRC Global management team, with the assistance of J.P. Morgan and Akin, discussed potential responses to the DNOW March 18 Letter, including responding with a potential counter proposal that contemplated a 44.5% pro forma ownership by MRC Global stockholders. The MRC Global board authorized Mr. Saltiel to arrange a meeting between each company’s respective chairpersons and chief executive officers to discuss, among other things, synergies and governance matters.

On March 25, 2025, Mr. Saltiel contacted Mr. Cherechinsky to discuss the terms of the DNOW March 18 Letter and previewed that MRC Global would be sending an updated proposal. On the same day, Mr. Saltiel emailed Mr. Cherechinsky a letter (the “MRC Global March 25 Letter”) with a non-binding proposal in response to the DNOW March 18 Letter. The MRC Global March 25 Letter stated that MRC Global believed that the DNOW March 18 Letter undervalued MRC Global relative to DNOW on a historical trading basis of the stocks of the two companies and proposed an exchange ratio of 0.9833, implying a 44.5% pro forma ownership of the combined company for MRC Global stockholders. The MRC Global March 25 Letter further proposed a meeting between Messrs. Saltiel, Cherechinsky and Alario and Ms. Adams to address key strategic and governance matters.

Later that same day, at the direction of MRC Global’s management and DNOW’s management, respectively, representatives of each of J.P. Morgan and Goldman Sachs discussed the MRC Global March 25 Letter, the proposed pro forma ownership and views on the companies’ historical relative trading prices, and, at the direction of DNOW’s management, representatives of Goldman Sachs noted that the MRC Global March 25 Letter suggests a large premium at which DNOW would be unwilling to transact.

On March 26, 2025, Mr. Cherechinsky called Mr. Saltiel to discuss the MRC Global March 25 Letter. Mr. Cherechinsky stated that DNOW was unwilling to transact at a premium of the magnitude implied by the MRC Global March 25 Letter, which DNOW estimated to be over 35%. He stated that he and Mr. Alario were willing to have a meeting with Mr. Saltiel and Ms. Adams to further discuss. Mr. Saltiel stated in response that without an increase in the pro forma ownership of the combined company by MRC Global stockholders, the MRC Global board was not willing to move forward. Mr. Cherechinsky reiterated he did not believe that there could be further movement on valuation of the magnitude implied by the MRC Global March 25 Letter, given the

69

##### Table of Contents

trading range between the two companies’ share prices at the time of the meeting. The two agreed to continue the discussion later in the day.

Later that same day, Mr. Cherechinsky called Mr. Saltiel, and each confirmed their respective positions remained unchanged from earlier that day. Mr. Saltiel informed Mr. Cherechinsky that, given the valuation gap, there was no need for a meeting among the companies’ respective chairs and chief executive officers. Mr. Cherechinsky stated that this effectively meant that both parties would terminate discussions at that time and that DNOW would focus on other potential opportunities and transactions, including to instruct its advisors to cease work on a potential transaction. Mr. Saltiel agreed with terminating the discussions at that time. Mr. Cherechinsky and Mr. Saltiel agreed that a potential transaction between the two companies continued to make industrial logic but that at the current valuation gap between the companies, a transaction did not appear viable.

From March 27, 2025 through May 18, 2025, the parties and their respective advisors did not have any substantive contact with respect to a potential transaction.

On May 1, 2025, the MRC Global board met at a regularly scheduled board meeting, with members of MRC Global management and representatives of each of Akin and J.P. Morgan in attendance. Among other matters, the MRC Global board discussed the status of the negotiations on a potential transaction with DNOW. Management confirmed that there had been no discussions with DNOW or its representatives since March 26, 2025. Members of MRC Global management and representatives of J.P. Morgan and Akin reviewed and discussed general market conditions, a range of implied premium and exchange ratios at current trading ranges between MRC Global and DNOW, potential synergies of a combined company, legal conditions of a stock for stock transaction, including stockholder approvals, timing of potential re-engagement with DNOW, potential benefits of a combined company, including scale and volume, and possible alternatives to a transaction with DNOW, including potential alternative counterparties.

On May 15, 2025, the MRC Global project committee met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Among other things, the MRC Global project committee discussed whether to attempt to re-start discussions with DNOW.

Morgan to contact representatives of Goldman Sachs to assess whether DNOW would be interested in restarting discussions regarding a potential combination.

On May 19, 2025, representatives of J.P. Morgan contacted representatives of Goldman Sachs to discuss whether DNOW was interested in resuming negotiations and such representatives discussed the relative performance of the parties’ respective stock prices over the past few weeks.

During an executive session, representatives of Goldman Sachs reviewed Goldman Sachs’ preliminary financial analyses of MRC Global, DNOW and a potential transaction based on publicly available information, including a review of the trading history of DNOW and MRC Global and the implied ownership and premia at various exchange ratios. The DNOW board and the representatives of each of Goldman Sachs and Kirkland discussed the process of restarting negotiations with MRC Global and potential next steps. After discussion, the DNOW board authorized and directed representatives of Goldman Sachs to convey an updated exchange ratio to J.P. Morgan of 0.9300 with no changes to any other terms of the DNOW March 18 Letter. Later that same day, at the direction of the DNOW board, representatives of Goldman Sachs called representatives of J.P. Morgan to convey DNOW’s renewed interest in the potential transaction.

On May 22, 2025, consistent with the direction from the DNOW board, representatives of Goldman Sachs contacted J.P.

After further discussion, the MRC Global board instructed representatives of J.P. Morgan to convey to representatives of Goldman Sachs a counteroffer of a pro forma share ownership of the combined company by MRC Global stockholders of 43.5% and to not address the governance issues at that time.

On May 27, 2025, representatives of J.P. Morgan contacted representatives of Goldman Sachs to convey MRC Global’s non-binding proposal of a 43.5% pro forma ownership of the combined company by MRC Global stockholders (the “MRC Global May 27 Proposal”).

The DNOW board affirmed the 43.5% pro forma ownership of the combined company for MRC Global stockholders set forth in the MRC Global May 27 Proposal. Later that same day, representatives of each of J. P. Morgan and Goldman Sachs met to discuss DNOW’s and MRC Global’s respective outstanding share counts.

On May 31, 2025, consistent with the direction from the DNOW board, representatives of Goldman Sachs contacted representatives of J.P. Morgan to reiterate the terms of the MRC Global May 27 Proposal, and illustrated that, accounting for each company’s share buyback activities, MRC Global stockholders would have 43.5% pro forma ownership of the combined company (or an exchange ratio of 0.9489), and that the governance of the combined company would comport with the terms outlined in the DNOW March 18 Letter (the “DNOW May 31 Proposal”). Later that same day, at the direction of MRC Global’s management, representatives of J.P. Morgan contacted representatives of Goldman Sachs and noted that the MRC Global board planned to meet on June 1, 2025 to discuss the DNOW May 31 Proposal.

On June 1, 2025, the MRC Global project committee met with members of MRC Global management and representatives of each of Akin and J.P. Morgan. Representatives of J.P. Morgan reviewed a summary of the discussions held with representatives of Goldman Sachs on May 27, 2025 and May 31, 2025 and reported that representatives of each of J.P. Morgan and Goldman Sachs had provided share count information to one another and that DNOW was prepared to proceed with due diligence and negotiation of definitive documentation assuming that MRC Global’s pro forma ownership of the combined company is 43.5%, or an exchange ratio of 0.9489, and that the governance of the combined company would comport with the terms outlined in the DNOW March 18 Letter. After discussion, the MRC Global project committee authorized and directed representatives of J.P. Morgan to proceed along the lines of the terms of the DNOW May 31 Proposal, subject to due diligence and negotiation and execution of mutually agreeable definitive documentation.

Later that same day, consistent with the direction from the MRC Global project committee, representatives of J.P. Morgan contacted representatives of Goldman Sachs to convey that MRC Global was prepared to proceed with a transaction consistent with DNOW’s May 31 Proposal, specifically at an exchange ratio of 0.9489, which would represent a 43.5% pro forma ownership of the combined company by MRC Global stockholders. J.P.

Morgan, consistent with the direction from the MRC Global project committee, conveyed to Goldman Sachs that MRC Global was amenable to the governance terms set forth in the DNOW March 18 Letter.

Also later that same day, Mr. Raymond Chang, DNOW’s general counsel, contacted the DNOW board to provide an update on the status of the negotiations, including that MRC Global was willing to transact on the basis of 43.5% pro forma ownership of the combined company by MRC Global stockholders, reflecting an exchange ratio of 0.9489. Mr. Chang noted that all parties were working towards executing the merger agreement and publicly announcing the transaction prior to the end of June, subject to completion of confirmatory due diligence and further negotiations, and that a status update would be provided later that week on the DNOW board update call.

On June 2, 2025, Mr. Saltiel contacted Mr. Cherechinsky to discuss the potential transaction, including the status of negotiations and the due diligence process.

On June 3, 2025, Kirkland provided an initial draft of the merger agreement to Akin. The draft contemplated, among other things, the following:

| • |  | the DNOW board would be increased by two seats and DNOW would appoint two directors who are existing independent directors of MRC Global to fill those vacancies at closing (“MRC Global board member designees”);

| • |  | customary representations and warranties and interim operating covenants for an acquisition transaction;

| • |  | largely reciprocal no-shop covenants applicable to DNOW and MRC Global;

| • |  | DNOW and MRC Global would (x) pay a termination fee based on an unspecified percentage of MRC Global’s equity value if the merger agreement were terminated in certain situations, including to allow the terminating party to enter into a superior proposal, and (y) reimburse the other party for expenses up to an unspecified cap if the agreement were terminated due to the failure to receive the applicable stockholder approval;

From June 3, 2025 through June 25, 2025, the parties conducted reciprocal legal, financial and operational due diligence and, together with representatives of their respective financial and legal advisors, participated in calls relating to litigation, human resources, employee benefits and personnel, regulatory, real estate, tax, insurance, environmental, health and safety and other matters.

On June 4, 2025, MRC Global formally amended its engagement of J.P. Morgan as its financial advisor pursuant to an amendment to the J.P. Morgan engagement letter dated June 4, 2025. On the same day, J.P. Morgan provided a customary relationship disclosure letter to the MRC Global board, which disclosed certain relationships between J.P. Morgan and its affiliates, on the one hand, and each of MRC Global and DNOW, on the other hand. The MRC Global board later considered such disclosures from J.P. Morgan and determined that J.P. Morgan did not have any material relationships with DNOW that would adversely affect its ability to act as financial advisor to MRC Global.

On June 6, 2025, the DNOW board met informally with Mr. Cherechinsky to discuss the terms of the potential transaction, including to affirm that the exchange ratio of 0.9489 would be fixed so long as the parties moved expeditiously to execute definitive agreements.

At its meeting held on June 26, 2025, after due consideration and consultation with DNOW management and outside legal and financial advisors, the DNOW board unanimously approved and declared advisable the merger agreement, the mergers and the other transactions contemplated by the merger agreement, including the DNOW stock issuance and recommended that DNOW stockholders vote in favor of the DNOW stock issuance. The DNOW board considered a number of factors (not necessarily in order of relative importance) that it viewed as being generally positive or favorable in coming to its determination, approval and related recommendation, including the following:

| • |  | the combined company would be a premier energy and industrial solutions provider with an enterprise value of approximately $3.0 billion;

| • |  | the combined company is expected to have strong cash flow generation capabilities and a robust balance sheet expected to provide liquidity and capital allocation flexibility to pursue organic and inorganic investments and return of capital;

| • |  | the expectation that the combined company would generate $70 million of cost synergies within three years following closing through public company costs, corporate and IT systems, and operational and supply chain efficiencies;

| • |  | the expectation that the combined company would accelerate growth and deliver double digit adjusted earnings per share accretion in the first year following closing;

| • |  | the fact that DNOW has secured commitments to expand its existing credit facility by $250 million and the expectation that the combined company would maintain a strong balance sheet and streamlined capital structure, with pro forma net leverage not greater than 0.5x at close and a net cash position by the first year post closing;

| • |  | the expectation that the combined company would have compelling and diverse growth opportunities and cash flow levers to reduce earnings volatility and enhance resilience through business cyclicality in the energy sectors;

| • |  | the expectation that the transaction would increase scale and scope across diverse industries and global markets, including non-oil and gas sectors, providing diversification and enhancing opportunities in alternative energy, artificial intelligence infrastructure, electrification, mining, and other industrial markets;

| • |  | the expectation that the transaction would provide a broader range of products, services and supply chain solutions, creating revenue streams across multiple industries and reducing reliance on any single sector;

| • |  | the combined company would offer distinctive and complementary products and services to the energy and industrial sectors across upstream, midstream, downstream, gas utility and industrial customers;

| • |  | the combined company would have an expanded geographic footprint and distribution presence in the U.S., Canada and attractive international markets, with approximately 5,000 team members and the expectation that the expanded range of products and solutions would strengthen existing customer and supplier relationships and facilitate the creation of new customer and supplier relationships;

| • |  | that the combined company will continue to be led by the DNOW management team and that the existing DNOW board members will continue to comprise over a majority of the board of directors and such continuity will enhance the likelihood of attaining the strategic benefits that DNOW expects to derive from the mergers;

| • |  | the financial analyses of Goldman Sachs, as reviewed and discussed with the DNOW board, as well as the opinion of Goldman Sachs to the effect that, as of June 26, 2025, and based upon and subject to the factors and assumptions set forth in Goldman Sachs’ opinion, the exchange ratio of 0.9489 shares of DNOW common stock to be issued in exchange for each outstanding share of MRC Global common stock (other than Excluded Shares) pursuant to the merger agreement was fair, from a financial point of view, to DNOW, as more fully described under “—Opinion of DNOW’s Financial Advisor” and the full text of the written opinion of Goldman Sachs, which is attached as Annex B to this joint proxy statement/prospectus;

| • |  | the information and discussions with DNOW management and outside legal and financial advisors regarding each of DNOW’s and MRC Global’s business, assets, financial condition, results of operations, current business strategy and prospects, including the projected financial results of each of DNOW and MRC Global as a standalone company, the size and scale of the combined company and the expected pro forma effect of the mergers on the combined company and its ability to achieve future growth and generate additional returns for DNOW stockholders;

| • |  | the DNOW board’s view, after consultation with DNOW management and its outside legal advisor, concerning the likelihood that regulatory approvals and clearances necessary to consummate the mergers would be obtained, without the imposition of conditions sufficiently material to preclude the mergers;

78

##### Table of Contents

| • |  | the review by the DNOW board with DNOW management and its outside legal advisor of the structure of the mergers and the financial and other terms of the merger agreement, including the parties’ representations, warranties and covenants, the conditions to their respective obligations and the termination provisions, as well as the likelihood of consummation of the proposed transaction and the evaluation of the DNOW board of the likely time period necessary to complete the mergers;

| • |  | the right of DNOW to terminate the merger agreement under certain circumstances, including, among others, if the consummation of the First Merger does not occur on or before June 26, 2026 (subject to two potential extensions to September 26, 2026 and December 26, 2026 if the required regulatory approvals have not been received but all other conditions to closing have been satisfied or waived (except for those conditions that by their nature are to be satisfied at closing)) and, subject to compliance with certain requirements and payment of a termination fee, to enter into a definitive agreement for a superior proposal;

| • |  | the agreement between DNOW and MRC Global to use reasonable best efforts to obtain approvals or clearances by applicable competition authorities; and

| • |  | DNOW’s ability, at any time prior to obtaining DNOW stockholder approval of the DNOW stock issuance proposal and under certain circumstances, to consider and respond to an unsolicited alternative proposal and to engage in discussions or negotiations with the person making such a proposal.

In addition, the DNOW board was aware of and considered the interests of its directors and executive officers that are different from, or in addition to, the interests of DNOW stockholders generally, including the fact that, upon completion of the mergers, certain, if not all, of the current executive officers of DNOW and all members of DNOW’s board of directors are expected to continue in their current roles with the combined company, as described in “—Board of Directors and Management of DNOW Following Completion of the Mergers.”

The DNOW board also considered a number of uncertainties, risks and other countervailing factors it deemed generally negative or unfavorable in making its determination, approval and related recommendation, including the following (not necessarily in order of relative importance):

| • |  | the fact that while the transaction is expected to be completed, there is no assurance that all conditions to the parties’ obligations to complete the transaction will be satisfied or waived, and as a result, it is possible that the transaction might not be completed even if approved by DNOW stockholders;

| • |  | the fact that completion of the transaction is subject to certain conditions, including expiration or termination of the waiting period under applicable regulatory laws, and the risk that such conditions may not be satisfied on acceptable terms or at all;

| • |  | the restrictions on the conduct of DNOW’s business prior to the consummation of the transaction, which may delay or prevent DNOW from undertaking business opportunities that may arise or other actions it would otherwise take with respect to the operations of DNOW pending consummation of the transaction;

| • |  | the risks and costs to DNOW if the transaction is delayed or does not occur at all, including the potential negative impact on DNOW’s ability to retain key employees, the diversion of DNOW management and employee attention and the potential disruptive effectives on DNOW’s day-to-day operations and DNOW’s relationships with third parties, including its customers and suppliers; the supplemental costs to be incurred in connection with the transaction, including the costs of integrating MRC Global’s business;

| • |  | the risks inherent in integrating the operations of MRC Global and DNOW, including the risk of not capturing all of the anticipated synergies and the risk that other anticipated benefits might not be realized;

| • |  | the ability of the MRC Global board to effect a change of recommendation in connection with a superior proposal or intervening event and the ability of MRC Global to terminate the merger agreement to accept a superior proposal, in each case, subject to certain conditions;

79

##### Table of Contents

| • |  | the fact that the merger agreement provides that, in certain circumstances, DNOW could be required to pay a termination fee of $45.5 million or expense reimbursement of up to $8.5 million to MRC Global;

| • |  | the risk of litigation arising from DNOW stockholders in respect of the merger agreement; and

| • |  | various other risks associated with the transactions and the business of DNOW, MRC Global and the combined company, some of which are described in “Risk Factors” and the matters described in “Cautionary Statement Regarding Forward-Looking Statements.”

The foregoing discussion of the information and factors that the DNOW board considered is not intended to be exhaustive, but rather is meant to include the material factors that the DNOW board considered. The DNOW board collectively reached the conclusion to approve the merger agreement, the mergers and the other transactions contemplated by the merger agreement in light of the various factors described above and other factors that the members of the DNOW board believed were appropriate. In view of the complexity and wide variety of factors, both positive and negative, that the DNOW board considered in connection with its evaluation of the mergers, the DNOW board did not find it practical, and did not attempt, to quantify, rank or otherwise assign relative or specific weights or values to any of the factors it considered in reaching its decision and did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate determination of the DNOW board. Moreover, each member of the DNOW board applied his or her own personal business judgment to the process and may have given different weight to different factors. The DNOW board based its recommendation on the totality of the information presented, including thorough discussions with, and questioning of, DNOW management and DNOW’s outside legal and financial advisors.

The foregoing description of the DNOW board’s consideration of the factors supporting the mergers is forward-looking in nature. This information should be read in light of the factors discussed in “Cautionary Statement Regarding Forward-Looking Statements.”

Recommendation of the MRC Global Board and Reasons for the Mergers

The MRC Global board, after thorough review and analysis and by unanimous vote at a meeting held on June 26, 2025, took the following actions:

| • |  | declared that the merger agreement, the mergers and the related transactions contemplated thereby are fair to and in the best interests of MRC Global and MRC Global stockholders,

| • |  | approved and declared advisable the merger agreement and the related transactions contemplated thereby, including the mergers, and

| • |  | directed that MRC Global submit the merger agreement for adoption at a meeting of MRC Global stockholders and recommended that MRC Global stockholders approve and adopt the merger agreement and the transactions contemplated thereby, including the mergers.

The MRC Global board unanimously recommends that MRC Global stockholders vote “FOR” the MRC Global merger proposal.

In reaching its decision to approve and declare advisable the merger agreement, and the completion of the mergers and the other transactions contemplated thereby, the MRC Global board, as described in the section entitled “— Background of the Mergers” beginning on page 63, held a number of meetings; consulted with the MRC Global project committee, MRC Global’s management and representatives of MRC Global’s legal counsel and financial advisor, Akin and J.P. Morgan, respectively; and considered the business, assets and liabilities, results of operations, financial performance, strategic direction and prospects of DNOW and MRC Global and other factors. The MRC Global board determined that the terms of the merger agreement, the mergers and the other transactions contemplated thereby are fair to, and in the best interests of, MRC Global and its stockholders.

80

##### Table of Contents

In evaluating the merger agreement, the mergers and the other transactions contemplated by the transaction documents, the MRC Global board determined that entering into the merger agreement with DNOW provided the best alternative for maximizing stockholder value reasonably available to MRC Global, including when compared to continuing to operate on a stand-alone basis.

In recommending that MRC Global stockholders vote their shares of MRC Global common stock in favor of adoption of the merger agreement, the mergers and the related transactions contemplated thereby, the MRC Global board considered a number of factors that the MRC Global board viewed as being generally positive or favorable in coming to its determination and recommendation, including the following factors (not necessarily in the order of relative importance):

| • |  | Superior Alternative to Continuation of MRC Global as a Stand-Alone Business. The MRC Global board considered the mergers to be a superior alternative to the continuation of MRC Global’s stand-alone business, prospects and opportunities and to the risks of remaining as a stand-alone public company, including the potential benefits expected to result from:

| • |  | the opportunity to increase scale by bringing together two global energy and industrial infrastructure organizations and their respective expertise in serving energy, gas utility and industrial customers to deliver enhanced capabilities across the value chain;

| • |  | scale should provide the combined company with the ability to spread fixed and public company costs across a wider revenue base and provide the combined company with the potential of a larger stock market capitalization to attract more investors and capital to the business for the benefit of stockholders with more trading liquidity in the combined company’s common stock;

| • |  | the opportunity to increase scope and a complementary and more diversified portfolio of high-quality products, services and supply chain solutions and an expanded footprint of service and distribution centers; at the time of the MRC Global board decision there were more than 350 service and distribution locations across more than 20 countries;

| • |  | the combination of complementary strengths that are expected to create a premier energy, gas utilities and industrial solutions provider by combining DNOW, a leading upstream and midstream solutions provider, with MRC Global, a leading downstream and gas utilities solutions provider; and

| • |  | the ability of the mergers to bring together similar corporate cultures focused on people, safety, innovation, collaboration, integrity, diversity and corporate social responsibility.

| • |  | Review of Potential Alternatives. The MRC Global board, from time to time, conducted reviews of potential alternatives to the mergers, including:

| • |  | pursuing alternative strategic transactions reasonably available to MRC Global and considering the potential value to MRC Global stockholders that might result from those alternatives, including the timing and likelihood of accomplishing and creating value in those alternatives, or

| • |  | refraining from the pursuit of any strategic transactions, including whether the historical and projected financial information concerning MRC Global’s business, financial performance and condition, results of operations, earnings, competitive position and prospects as a stand-alone company support that approach.

The MRC Global board assessed that none of these alternatives were reasonably likely to result in greater value for the MRC Global stockholders in a reasonable timeframe than the mergers and the related transactions contemplated thereby.

| • |  | Future Value and Growth of Combined Company. The MRC Global board considered that, due to the minimal existing overlap in the markets that each of DNOW and MRC Global serves, the combination will create a diversified business with enhanced growth opportunities and reduced exposure to earnings volatility given DNOW and MRC Global’s highly complementary footprints across key energy and

81

##### Table of Contents

| industrial hubs in the U.S. and in attractive global growth markets, as well as a broader and more diversified mix of customers with enhanced opportunities, including in alternative energy, AI infrastructure, electrification, industrial process, municipal water, chemicals and mining sectors.

| • |  | Synergies. The MRC Global board considered the scale and synergies that the parties expect the combined company to achieve, including through enhanced direct and indirect procurement capabilities, to provide greater value to customers, and, based upon available information, expects that the combined company will realize at least approximately $70 million of annual cost synergies within three years following closing.

| • |  | Benefits Financial Strength and Credit Profile. The MRC Global board considered that the parties expect the mergers to enhance the combined company’s credit profile, resulting in a net leverage at closing of less than 0.5x, which together with net cash on hand and available capacity under credit facilities, can provide additional liquidity and capital allocation flexibility than MRC Global would otherwise realize on a standalone basis.

| • |  | Exchange Ratio and Form of Merger Consideration. The MRC Global board considered that the exchange ratio of 0.9489 shares of DNOW common stock for each share of MRC Global’s common stock is fixed and that the value offered by the exchange ratio represented:

| • |  | an 8.5% premium to MRC Global’s 30-day volume weighted average price (“VWAP”) of $12.77 as of June 25, 2025, and

| • |  | a 15% premium to MRC Global’s 60-day VWAP of $11.84 as of June 25, 2025.

| • |  | Pro Forma Ownership of the Combined Company. The MRC Global board considered that MRC Global stockholders immediately prior to the completion of the mergers will hold, in the aggregate, approximately 43.5% of the issued and outstanding shares of DNOW common stock, pro forma for the mergers, on a fully diluted basis and based on the number of outstanding shares as of June 25, 2025.

| • |  | Participation in the Combined Company. The MRC Global board considered that the all-stock merger consideration will allow MRC Global stockholders to participate in the anticipated benefits of the combined company, including operational and financial synergies, future growth, substantial and more sustainable free cash flow generation, enhanced capital allocation flexibility and reduced volatility.

| • |  | Business and Legal Due Diligence. The MRC Global board considered its review of materials that MRC Global’s financial and legal advisors, together with senior members of MRC Global’s management, prepared, and related discussions with those advisors and management concerning MRC Global’s due diligence examination of the operations, financial condition, credit quality and earnings and legal compliance of DNOW.

| • |  | Tax Considerations. The MRC Global board considered that the mergers are intended to qualify as a “reorganization” for the purposes of Section 368(a) of the Code.

| • |  | Review of the Merger Agreement. The MRC Global board considered in its review, with its legal advisor, the financial and other material terms of the merger agreement and the corresponding disclosure letters, including the following:

| • |  | the structure of the mergers,

| • |  | the parties’ respective representations and warranties,

| • |  | the parties’ respective covenants,

| • |  | MRC Global’s ability, under circumstances, to consider an unsolicited acquisition proposal,

| • |  | MRC Global’s ability to terminate the merger agreement to enter into a definitive agreement with respect to a superior proposal or in connection with an intervening event (subject to payment of a termination fee of $45.5 million),

82

##### Table of Contents

| • |  | the conditions to the parties’ respective obligations, and

| • |  | the termination provisions, as well as the likelihood of completion of the mergers and the evaluation of MRC Global board of the likely time period necessary to complete the mergers.

| • |  | Opinion of J.P. Morgan Securities LLC. The MRC Global board considered the financial analyses presented by J.P. Morgan to the MRC Global board and the June 26, 2025 oral opinion that J.P. Morgan rendered to the MRC Global board, which J.P. Morgan subsequently confirmed by delivery of a written opinion, dated June 26, 2025, to the effect that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review that J.P. Morgan undertook in preparing its opinion, the exchange ratio in the proposed First Merger was fair, from a financial point of view, to the MRC Global stockholders, as more fully described below in the section entitled “Opinion of MRC Global’s Financial Advisor” beginning on page 100. The full text of J.P. Morgan’s written opinion, dated June 26, 2025, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review that J.P. Morgan undertook in preparing its opinion, is attached as Annex C to this joint proxy statement/prospectus and is incorporated in this joint proxy statement/prospectus by reference. The summary of J.P. Morgan’s opinion set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of J.P. Morgan’s opinion.

| • |  | Director Representation. The MRC Global board considered that the merger agreement provides that two members of the MRC Global board will become members of a ten-member board of directors of the combined company and provide the combined company’s board with continuity and knowledge of MRC Global’s business, prospects and opportunities and oversight relating to the realization of anticipated synergies.

| • |  | Likelihood of Closing. The MRC Global board considered the likelihood that the mergers will be completed, including after consideration of the risks related to certain conditions and regulatory approvals required to complete the mergers.

| • |  | Extensive Negotiations. The MRC Global board considered that the terms and conditions of the merger agreement were the product of extensive negotiations between MRC Global and its advisors, on the one hand, and DNOW and its advisors, on the other hand.

| • |  | MRC Stockholder Approval. The MRC Global board considered the ability of the MRC Global stockholders to approve or reject the mergers by voting on the MRC Global merger proposal and that MRC Global will not be obligated to pay more than $8.5 million to reimburse DNOW’s expenses in the event that MRC Global stockholders reject the MRC Global merger proposal; see the section entitled “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” beginning on page 148.

The MRC Global board also considered a number of uncertainties, risks and factors it deemed generally negative or unfavorable in making its determination, approval and related recommendation, including the following (not necessarily in order of relative importance):

| • |  | Combined Business Governance and Leadership. The MRC Global board considered the risks associated with the governance and management of the combined company, including the expectation that the combined company is not expected to continue the employment of the members of MRC Global’s senior management team (consisting of MRC Global’s president & chief executive officer, executive vice president & chief financial officer, and executive vice president – corporate affairs, general counsel & corporate secretary) and that only two current members of the MRC Global board will continue on the combined company board.

| • |  | Loss of Key Employees. The MRC Global board considered the risk of losing key employees during the pendency of the mergers and thereafter. However, based on discussions with members of DNOW’s senior management, the MRC Global board believes that the combination of DNOW and MRC Global

83

##### Table of Contents

| provides opportunity for the combined company to use a “best athlete” approach for key supervisory and management positions, which the MRC Global board expects to create value for the combined company.

| • |  | Integration of Operations and Personnel; Realization of Synergies. The MRC Global board considered risks associated with the integration of the two companies, including:

| • |  | difficulties in eliminating redundancies in the combined company;

| • |  | management challenges inherent in completing the mergers and integrating the businesses, operations and workforce of MRC Global with those of DNOW; and

| • |  | the risk that all of the anticipated cost savings, synergies and other anticipated benefits of the mergers might not be realized.

| • |  | Regulatory Risk. The MRC Global board considered the risks associated with the regulatory and other approvals required in connection with the mergers and the risk that those approvals will not be received or will not be received in a timely manner or may impose burdensome or unacceptable conditions that may adversely affect the anticipated operations, synergies and financial results of the combined company following the completion of the mergers; see the section entitled “— Regulatory Approvals” beginning on page 118.

| • |  | Interim Operating Covenants. The MRC Global board considered the risks associated with, and discussed with senior members of MRC Global’s management team about, the restrictions on the conduct of MRC Global’s business during the period between execution of the merger agreement and the consummation of the mergers, including that MRC Global must conduct its business only in the ordinary course, subject to specific limitations, which could potentially delay or prevent MRC Global from undertaking business opportunities that might arise or certain other actions it might otherwise take with respect to its operations absent the pendency of the mergers.

| • |  | Consummation Delays. The MRC Global board considered the risk that the mergers may not be completed despite the combined efforts of DNOW and MRC Global as completion may be unduly delayed, including as a result of delays in obtaining the requisite regulatory approvals.

| • |  | Financial Performance. The MRC Global board considered that DNOW’s financial performance may not meet MRC Global’s expectations.

| • |  | Closing. The MRC Global board considered the amount of time it could take to complete the mergers, including that completion of the mergers depends on factors outside of DNOW and MRC Global’s control, and the risk that the pendency of the mergers for an extended period of time following the announcement of the execution of the merger agreement could have an adverse impact on DNOW and MRC Global, including their respective customer, supplier, employee and other business relationships.

| • |  | Management Attention. The MRC Global board considered risks of diverting management attention and resources from the operation of MRC Global’s business during the pendency of the mergers.

| • |  | DNOW Recommendation. The MRC Global board considered that the DNOW board may, under certain circumstances specified in the merger agreement, withhold, withdraw, qualify or change its recommendation to DNOW stockholders to vote “FOR” the DNOW stock issuance proposal.

| • |  | DNOW Stockholder Approval. The MRC Global board considered the ability of DNOW stockholders to approve or reject the DNOW stock issuance proposal by voting at the DNOW stockholder meeting and that DNOW will not be obligated to pay more than $8.5 million to reimburse MRC Global’s expenses in the event that DNOW stockholders reject the DNOW stock issuance proposal; see section entitled “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” beginning on page 148.

| • |  | DNOW Expense Reimbursement. The MRC Global board considered the risk that the $8.5 million expense reimbursement to which MRC Global may be entitled, subject to the terms and conditions of

84

##### Table of Contents

| the merger agreement, if DNOW terminates the merger agreement in certain circumstances may not be sufficient to compensate MRC Global for the expenses incurred in connection with the contemplated transaction, as described in the section entitled “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” beginning on page 148.

| • |  | Spot Premium. The MRC Global board considered that, on June 25, 2025, the exchange ratio value represented a 6.8% premium to MRC Global’s one-day VWAP, or “spot premium,” which was (i) lower than historical averages, (ii) indicative of an erosion of the anticipated implied premium to MRC Global stockholders, while still being representative of a supportable implied premium, and (iii) primarily attributable to DNOW’s spot price on June 25, 2025, which, reportedly, had been adversely impacted by low volume trades consisting primarily of a handful of block trades.

| • |  | No Solicitation; MRC Global Termination Fees. The MRC Global board considered the provisions of the merger agreement that prohibit MRC Global from soliciting or entertaining an MRC Global acquisition proposal and how those provisions, although reciprocal, restrict MRC Global’s ability to solicit, respond to and negotiate an MRC Global acquisition proposal from a third party, which may have the effect of discouraging an MRC Global acquisition proposal. Additionally, the MRC Global board considered the potential payment to DNOW by MRC Global of a termination fee of $45.5 million, as described in the section entitled “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” beginning on page 148.

| • |  | DNOW Termination Fees. The MRC Global board considered the risk that the $45.5 million termination fee to which MRC Global may be entitled, subject to the terms and conditions of the merger agreement, if DNOW terminates the merger agreement in certain circumstances may not be sufficient to compensate MRC Global for the harm it might suffer as a result of such termination, as described in the section entitled “The Merger Agreement — Expenses and Termination Fees Relating to the Termination of the Merger Agreement” beginning on page 148.

| • |  | Litigation Risk. The MRC Global board considered the potential for litigation relating to the mergers and the associated costs, burden and inconvenience involved in defending such proceedings.

| • |  | Fixed Exchange Ratio. The MRC Global board considered the potential that the exchange ratio under the merger agreement could result in MRC Global stockholders receiving less implied value per share of MRC Global common stock in the mergers than MRC Global anticipated should the value of the shares of MRC Global common stock increase relative to the value of DNOW common stock prior to closing.

| • |  | Fees and Expenses. The MRC Global board considered the fees and expenses associated with completing the mergers.

| • |  | Risk Factors. The MRC Global board considered the risks of the type and nature described above in “Risk Factors” and the matters described in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on pages 30 and 43, respectively.

The MRC Global board believed that, overall, the potential benefits of the transactions to MRC Global stockholders outweighed the risks and uncertainties of the transactions.

The foregoing discussion of factors that the MRC Global board considered in reaching its conclusions and recommendation includes the principal and material factors that the MRC Global board considered. It is not intended to be exhaustive or complete and may not include all items that the MRC Global board considered. Given the significant extent of tangible and strategic matters involved in its evaluation of the transactions, the MRC Global board did not find it practicable to, and did not, quantify or otherwise assign relative or specific weights to the specific factors considered in reaching its determinations and recommendation. Rather, the MRC Global board viewed its decisions as being based on the totality of the factors and information it considered. Moreover, each member of the MRC Global board applied their own personal business judgment and experience to the process and may have given different weight to different factors. The MRC Global board based its

85

recommendation on the totality of the information available to it, including discussions with MRC Global’s management and outside legal and financial advisors.

It should be noted that this explanation of the reasoning of the MRC Global board and certain information presented in this section is forward-looking in nature and should be read in light of the factors set forth in “Cautionary Statement Regarding Forward-Looking Statements.”

Certain Unaudited Prospective Financial and Operating Information

DNOW Forecasted Financial Information

DNOW, as a general matter of course, does not make public long-term forecasts or projections as to future performance, revenues, earnings or other results due to, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. However, in connection with DNOW’s evaluation of the mergers and not for public disclosure, DNOW management provided (i) to the DNOW board, MRC Global and DNOW’s financial advisor certain unaudited internal financial forecasts with respect to DNOW on a standalone basis and pro forma for the mergers, including certain operating synergies projected by DNOW’s management to result from the mergers, prepared by DNOW management and (ii) to the DNOW board and its financial advisor, certain unaudited financial forecasts with respect to MRC Global on a standalone basis prepared by MRC Global management and which the DNOW board authorized DNOW’s financial advisor to use and rely upon in connection with its financial analyses, in each case as discussed below (collectively, the “DNOW Forecasted Financial Information”).

The DNOW Forecasted Financial Information was not prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information. The DNOW Forecasted Financial Information was provided by DNOW to Goldman Sachs for its use and reliance in connection with its financial analyses and opinion as described in the section entitled “— Opinion of DNOW’s Financial Advisor.” The inclusion of this DNOW Forecasted Financial Information should not be regarded as an indication that any of DNOW, MRC Global, their respective affiliates, officers, directors, advisors or other representatives or any other recipient of this DNOW Forecasted Financial Information considered, or now considers, it to be necessarily predictive of actual future performance or events, or that it should be construed as financial guidance, and such summary projections set forth below should not be relied on as such.

The DNOW Forecasted Financial Information includes non-GAAP financial measures, including EBITDA excluding other costs, Adjusted EBITDA and Free Cash Flow. Please see the tables below for a description of how DNOW defines these non-GAAP financial measures. DNOW believes that EBITDA excluding other costs and Adjusted EBITDA provide information useful in assessing operating and financial performance across periods, and Free Cash Flow provides a useful measure of available cash generated by operating activities for investing, to reduce leverage or make distributions. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in accordance with GAAP, and non-GAAP financial measures used by DNOW may not be comparable to similarly titled measures used by other companies.

The DNOW Forecasted Financial Information was prepared solely for internal use and is subjective in many respects. While presented with numeric specificity as of the date on which such forecasts were finalized, the DNOW Forecasted Financial Information reflects numerous estimates and assumptions that are inherently uncertain and may be beyond the control of DNOW and MRC Global management teams, including with respect to, among others, DNOW’s and/or MRC Global’s future results, changes in oil and gas prices, changes in the energy markets, customer demand for DNOW or MRC Global’s products, changes in applicable regulations, difficulties encountered in integrating mergers and acquisitions, general economic and regulatory conditions and other matters described in the sections entitled “Cautionary Statement Regarding Forward-Looking Statements,”

##### Table of Contents

“Where You Can Find More Information” and “Risk Factors.” The DNOW Forecasted Financial Information reflects both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. DNOW and its affiliates, officers, directors, advisors or other representatives cannot give assurance that the DNOW Forecasted Financial Information and the underlying estimates and assumptions will be realized. This DNOW Forecasted Financial Information constitutes “forward-looking statements” and actual results may differ materially and adversely from those set forth below.

DNOW’s current independent registered public accounting firm, KPMG LLP (“KPMG”), has not audited, reviewed, examined, compiled or applied agreed-upon procedures with respect to the accompanying DNOW Forecasted Financial Information and, accordingly, KPMG does not express an opinion or any other form of assurance with respect thereto nor has it expressed any opinion or any other form of assurance on such information or its achievability, and assumes no responsibility for, and disclaims any association with, the prospective financial information. The reports of Ernst & Young LLP, DNOW’s former independent registered public accounting firm, incorporated by reference in this joint proxy statement/prospectus relate to DNOW’s previously issued historical financial statements.

DNOW Projections for Expected Synergies and Cost Savings

In connection with DNOW’s evaluation of the mergers, DNOW management provided to the DNOW board and DNOW’s financial advisor certain estimates of the amounts and timing of expected synergies anticipated by DNOW management to result from the mergers, which included cumulative cost savings of approximately $269,000,000 for the years 2025 through 2030 (the “Synergies”).

DNOW DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE DNOW FORECASTED FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN MADE OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH FORECASTED FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE, EXCEPT AS MAY BE REQUIRED BY APPLICABLE LAW.

MRC Global Forecasted Financial Information

MRC Global, as a matter of course, does not disclose publicly its long-term forecasts or internal projections as to future earnings or other results due to, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. However, in connection with the MRC Global board’s evaluation of the mergers, and not for public disclosure, MRC Global management prepared and provided to the MRC Global board certain unaudited prospective financial information relating to MRC Global on a standalone basis for the fiscal years ending December 31, 2025 through December 31, 2031, which is referred to as the “MRC Global Projections for MRC Global,” and certain unaudited prospective financial information relating to DNOW for the fiscal years ending December 31, 2025 through December 31, 2031, which is referred to as the “MRC Global Projections for DNOW.” The MRC Global Projections for MRC Global and the MRC Global Projections for DNOW, along with the information in this joint proxy statement/prospectus describing the same, are collectively referred to in this joint proxy statement/prospectus as the “MRC Global Projections.” The MRC Global Projections for MRC Global were prepared under the supervision of MRC Global management on a consistent basis as regular prospective financial information prepared under the supervision of MRC Global management in the ordinary course of MRC Global’s financial forecasting, planning and budgeting, updated for the most recently available information and assumptions. The MRC Global Projections for DNOW were prepared under the supervision of MRC Global management based on unaudited prospective financial information of DNOW that DNOW management provided to MRC Global as described under “—Certain Unaudited Prospective Financial and Operating Information—DNOW Forecasted Financial Information.” MRC Global authorized its financial advisor, J.P. Morgan, to use and rely upon the MRC Global Projections for MRC Global and the MRC Global Projections for DNOW in connection with its financial analyses and its opinion, as more fully described in the section entitled “—Opinion of MRC Global’s Financial Advisor.” Certain other unaudited prospective financial information relating to MRC Global also was provided to DNOW and its financial advisor.

The summary of the MRC Global Projections below is not included to influence the decision of MRC Global stockholders or DNOW stockholders whether to vote to approve the mergers, the DNOW stock issuance or any other proposal to be considered at the special meetings but is provided solely because it was made available to the MRC Global board and MRC Global’s financial advisor in connection with the mergers. The inclusion of the below information should not be regarded as an indication that any of MRC Global, DNOW, their respective advisors or other representatives or any other recipient of this information considered—or now considers—it to be necessarily predictive of actual future results, or that it should be construed as financial guidance, and such summary projections set forth below should not be relied on as such.

This information was prepared solely for internal use and is subjective in many respects. While presented with numerical specificity, the MRC Global Projections reflects numerous estimates and assumptions that are inherently uncertain and may be beyond the control of MRC Global’s or DNOW’s management, including, among others, the factors described in the sections entitled “Cautionary Statement Regarding Forward-Looking Statements,” “Where You Can Find More Information” and “Risk Factors.”

The MRC Global Projections also reflects assumptions as to certain business decisions that are subject to change and subjective judgment that is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. MRC Global can give no assurance that the MRC Global Projections and the underlying estimates and assumptions will be realized. In addition, since the MRC Global Projections covers multiple years, this information by its nature becomes less predictive with each successive year. This information constitutes “forward-looking statements” and actual results may differ materially and adversely from those projected. Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the unaudited prospective financial to be inaccurate include, but are not limited to, risks and uncertainties relating to its business, industry performance, the regulatory environment, general business and economic conditions and other matters described in the sections entitled “Cautionary Statement Regarding Forward-Looking Statements,” “Risk Factors” and “Where You Can Find More Information.”

The MRC Global Projections was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither MRC Global’s independent registered public accounting firm nor any other independent accountants have compiled, examined or performed any procedures with respect to the MRC Global Projections, nor have they expressed any opinion or any other form of assurance on this information or its achievability. The report of the independent registered public accounting firm to MRC Global contained in its Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference into this joint proxy statement/prospectus, relates to historical financial information of MRC Global, and that report does not extend to the MRC Global Projections and should not be read to do so.

Furthermore, the MRC Global Projections do not take into account any circumstances or events occurring after the date that MRC Global management prepared them. MRC Global can give no assurance that, had it prepared the MRC Global Projections as of the date of this joint proxy statement/prospectus, it would use similar estimates and assumptions. Except as applicable securities laws requires, MRC Global does not intend to, and disclaims any obligation to, make publicly available any update or other revision to the MRC Global Projections to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even if any or all of the underlying assumptions are shown to be inappropriate, including with respect to the accounting treatment of the merger under GAAP, or to reflect changes in general economic or industry conditions. The MRC Global Projections do not take into account all the possible financial and other effects on MRC Global or DNOW of the mergers, the effect on MRC Global or DNOW of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed but were instead altered, accelerated, postponed or not taken in anticipation of the mergers. Further, the MRC Global Projections do not take into account the effect on MRC Global or DNOW of any possible failure of the mergers to occur. None of MRC Global, DNOW or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any stockholder or other person regarding MRC Global’s or DNOW’s ultimate performance compared to the information contained in the MRC Global Projections or that the forecasted results will be achieved. The inclusion of the MRC Global Projections in this joint proxy statement/prospectus should not be deemed an admission or representation by MRC Global, DNOW or their respective advisors or other representatives or any other person that it is viewed as material information of MRC Global or DNOW, particularly in light of the inherent risks and uncertainties associated with the MRC Global Projections.

In light of the foregoing, and considering that the special meetings will be held some time after MRC Global management prepared the MRC Global Projections, as well as the uncertainties inherent in any forecasted information, MRC Global stockholders and DNOW stockholders are cautioned not to place undue reliance on the MRC Global Projections and are encouraged to review MRC Global’s and DNOW’s most recent SEC filings for

MRC Global Management Projections for Expected Synergies and Cost Savings

In connection with MRC Global’s evaluation of the mergers, MRC Global’s management provided to the MRC Global board and MRC Global’s financial advisor certain estimates of the amounts and timing of expected synergies that MRC Global management anticipated to result from the mergers, which included estimated run rate synergies of approximately $70 million per year to be fully achieved by the third year after the closing of the mergers. MRC Global authorized J.P. Morgan to use and rely upon these estimates in connection with its financial analyses and its opinion, as more fully described in the section entitled “—Opinion of MRC Global’s Financial Advisor.”

MRC GLOBAL DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE MRC GLOBAL PROJECTIONS TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN MADE OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH MRC GLOBAL PROJECTIONS ARE NO LONGER APPROPRIATE, EXCEPT AS MAY BE REQUIRED BY APPLICABLE LAW.

Opinion of DNOW’s Financial Advisor

Goldman Sachs rendered its opinion to the DNOW board that, as of June 26, 2025 and based upon and subject to the factors and assumptions set forth therein, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to DNOW.

The full text of the written opinion of Goldman Sachs, dated June 26, 2025, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B to this joint proxy statement/prospectus. Goldman Sachs provided advisory services and its opinion for the information and assistance of DNOW’s board of directors in connection with its consideration of the mergers. Goldman Sachs’ opinion is not a recommendation as to how any holder of DNOW common stock should vote with respect to the transactions contemplated by the merger agreement or any other matter.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

| • |  | the merger agreement;

| • |  | annual reports to stockholders and Annual Reports on Form 10-K of DNOW and MRC Global for the five years ended December 31, 2024;

| • |  | certain interim reports to stockholders and Quarterly Reports on Form 10-Q of DNOW and MRC Global for the quarter ended March 31, 2025;

| • |  | certain other communications from DNOW and MRC Global to their respective stockholders;

| • |  | certain publicly available research analyst reports for DNOW and MRC Global; and

| • |  | certain internal financial analyses and forecasts for MRC Global prepared by its management (referred to as the “MRC Global Standalone Projections,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”) and certain internal financial analyses and forecasts

| for DNOW standalone prepared by its management (referred to as the “DNOW Standalone Projections,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”) and pro forma for the mergers (referred to as the “DNOW Pro Forma Projections,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”), including certain operating synergies projected by the management of DNOW to result from the mergers (referred to as the “Synergies,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”), as prepared by the management of DNOW, and in each case, approved for Goldman Sachs’ use by DNOW (referred to collectively as the “Projections,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”); and certain internal forecasts related to the expected utilization by DNOW of certain net operating loss carryforwards and tax credits, as prepared by DNOW’s management and approved for Goldman Sachs’ use by DNOW (referred to as the “NOL Projections,” as described in the section titled “—Certain Unaudited Prospective Financial and Operating Information”).

Goldman Sachs also held discussions with members of the senior managements of DNOW and MRC Global regarding their assessment of the past and current business operations, financial condition and future prospects of MRC Global and with the members of senior management of DNOW regarding their assessment of the past and current business operations, financial condition and future prospects of DNOW and the strategic rationale for, and the potential benefits of, the mergers; reviewed the reported price and trading activity for the shares of DNOW common stock and the shares of MRC Global common stock; compared certain financial and stock market information for DNOW and MRC Global with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations; and performed such other studies and analyses, and considered such other factors, as it deemed appropriate.

For purposes of rendering its opinion, Goldman Sachs, with DNOW’s consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, it, without assuming any responsibility for independent verification thereof. In that regard, Goldman Sachs assumed with DNOW’s consent that the Projections, including the Synergies, and the NOL Projections were reasonably prepared on a basis reflecting the best then available estimates and judgments of the management of DNOW. Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of DNOW or MRC Global or any of their respective subsidiaries and it was not furnished with any such evaluation or appraisal. Goldman Sachs assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the mergers will be obtained without any adverse effect on DNOW or MRC Global or on the expected benefits of the mergers in any way meaningful to its analysis. Goldman Sachs also assumed that the mergers will be consummated on the terms set forth in the merger agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to its analysis.

Goldman Sachs’ opinion does not address the underlying business decision of DNOW to engage in the mergers, or the relative merits of the mergers as compared to any strategic alternatives that may be available to DNOW; nor does it address any legal, regulatory, tax or accounting matters. Goldman Sachs’ opinion addresses only the fairness from a financial point of view to DNOW, as of the date of the opinion, of the exchange ratio pursuant to the merger agreement. Goldman Sachs’ opinion does not express any view on, and does not address, any other term or aspect of the merger agreement or the mergers or any term or aspect of any other agreement or instrument contemplated by the merger agreement or entered into or amended in connection with the mergers, including the fairness of the mergers to, or any consideration received in connection therewith by, the holders of any class of securities, creditors, or other constituencies of DNOW; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of DNOW or MRC Global, or any class of such persons in connection with the mergers, whether relative to the exchange ratio pursuant to the merger agreement or otherwise. Goldman Sachs’ opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Goldman Sachs as

In addition, Goldman Sachs does not express any opinion as to the prices at which shares of DNOW common stock or MRC Global common stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on DNOW or MRC Global or the mergers, or as to the impact of the mergers on the solvency or viability of DNOW or MRC Global or the ability of DNOW or MRC Global to pay their respective obligations when they come due. Goldman Sachs’ opinion was approved by a fairness committee of Goldman Sachs.

The following is a summary of the material financial analyses delivered by Goldman Sachs to the DNOW board in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs, nor does the order of analyses described represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before June 25, 2025, the last trading day before the public announcement of the mergers, and is not necessarily indicative of current market conditions.

Implied Premia

Goldman Sachs reviewed the historical trading prices for MRC Global common stock for the two-year period ended June 25, 2025. In addition, Goldman Sachs compared the premia represented by the implied value of $13.85 per share of MRC Global common stock reflecting the exchange ratio pursuant to the merger agreement (calculated by multiplying the exchange ratio of 0.9489 by $14.60, the closing price for the shares of DNOW common stock on June 25, 2025) in relation to:

| • |  | $12.97, the closing price of the shares of MRC Global common stock on June 25, 2025 (referred to as the “current share price”);

| • |  | $12.94, the volume weighted average price (referred to as the “VWAP”) of the shares of MRC Global common stock during the 10 trading-day period ended June 25, 2025 (referred to as the “10-day VWAP”);

| • |  | $12.77, the VWAP of the shares of MRC Global common stock during the 20 trading-day period ended June 25, 2025 (referred to as the “20-day VWAP”); and

| • |  | $15.27, the highest closing trading price of the shares of MRC Global common stock for the 52-week period ended June 25, 2025 (referred to as the “52-week high price”).

This analysis indicated that the price per share to be paid to MRC Global stockholders pursuant to the merger agreement represented:

| • |  | a premium of 6.8% based on the current share price of $12.97;

| • |  | a premium of 7.1% based on the 10-day VWAP of $12.94;

| • |  | a premium of 8.5% based on the 20-day VWAP of $12.77; and

| • |  | a discount of (9.3)% based on the 52-week high price of $15.27.

Historical Exchange Ratio Analysis

Goldman Sachs calculated historical daily average exchange ratios for shares of DNOW common stock and MRC Global common stock over various periods from June 25, 2023 to June 25, 2025, by dividing the price per share of MRC Global common stock by the price per share of DNOW common stock based on publicly available historical data and information Goldman Sachs obtained from FactSet, including: (i) the closing price of shares of

##### Table of Contents

MRC Global common stock and DNOW common stock on June 25, 2025, (ii) the closing prices of shares of MRC Global common stock and DNOW common stock during the 10 trading-day period ended on June 25, 2025, (iii) the closing prices of shares of MRC Global common stock and DNOW common stock during the 20 trading-day period ended on June 25, 2025, (iv) the closing prices of shares of MRC Global common stock and DNOW common stock during the 30 trading-day period ended on June 25, 2025, (v) the closing prices of shares of MRC Global common stock and DNOW common stock during the year-to-date period ended on June 25, 2025, (vi) the closing prices of shares of MRC Global common stock and DNOW common stock during the one-year period ended on June 25, 2025 and (vii) the closing prices of shares of MRC Global common stock and DNOW common stock during the two-year period ended on June 25, 2025. Goldman Sachs then calculated the implied premia of each of the foregoing exchange ratios in relation to the exchange ratio. The results of these calculations are as follows:

Illustrative Discounted Cash Flow Analysis

DNOW on a Standalone Basis. Using the DNOW Standalone Projections, Goldman Sachs performed an illustrative discounted cash flow analysis on DNOW to derive a range of illustrative present values per share of DNOW common stock. Using the mid-year convention for discounting cash flows and discount rates ranging from 10.0% to 12.0%, reflecting estimates of DNOW’s weighted average cost of capital, Goldman Sachs discounted to present value as of March 31, 2025 (i) estimates of unlevered free cash flow for DNOW for the last three fiscal quarters of the fiscal year 2025 and the fiscal years 2026 through 2029 as reflected in the DNOW Standalone Projections (taking into account the NOL Forecasts) and (ii) a range of illustrative terminal values for DNOW, which were calculated by applying terminal year exit multiples of enterprise value (referred to as “EV”) to estimated adjusted earnings before interest, taxes, deprecation and amortization (referred to as “EBITDA” and such multiple referred to as “EV/EBITDA”) ranging from 6.5x to 7.5x, to a terminal year estimate of the EBITDA to be generated by DNOW (which analysis implied perpetuity growth rates ranging from 0.8% to 3.8%), as reflected in the DNOW Standalone Projections (taking into account the NOL Forecasts). The range of terminal year exit EV/EBITDA multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account historical trading multiples of DNOW. Goldman Sachs derived such discount rates by application of the Capital Asset Pricing Model (referred to as “CAPM”), which requires certain company-specific inputs, including DNOW’s target capital structure weightings, the cost of long-term debt, future applicable marginal cash tax rate and a beta for DNOW, as well as certain financial metrics for the United States financial markets generally.

Goldman Sachs derived a range of illustrative EVs for DNOW by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for DNOW the amount of DNOW’s net debt and non-controlling interest, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for DNOW. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of DNOW, as provided by and approved for Goldman Sachs’ use by the management of DNOW, using the treasury stock method, to derive a range of illustrative present values per share ranging from $15.70 to $18.66.

MRC Global on a Standalone Basis. Using the MRC Global Standalone Projections, Goldman Sachs performed an illustrative discounted cash flow analysis on MRC Global to derive a range of illustrative present

values per share of MRC Global common stock. Using the mid-year convention for discounting cash flows and discount rates ranging from 11.0% to 13.0%, reflecting estimates of MRC Global’s weighted average cost of capital, Goldman Sachs discounted to present value as of March 31, 2025 (i) estimates of unlevered free cash flow for MRC Global for the last three fiscal quarters of the fiscal year 2025 and the fiscal years 2026 through 2029 as reflected in the MRC Global Standalone Projections and (ii) a range of illustrative terminal values for MRC Global, which were calculated by applying terminal year exit EV/EBITDA multiples ranging from 6.5x to 7.5x, to a terminal year estimate of the EBITDA to be generated by MRC Global (which analysis implied perpetuity growth rates ranging from 1.7% to 4.7%), as reflected in the MRC Global Standalone Projections. The range of terminal year exit EV/EBITDA multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account historical trading multiples of MRC Global. Goldman Sachs derived such discount rates by application of the CAPM, which requires certain company-specific inputs, including MRC Global’s target capital structure weightings, the cost of long-term debt, future applicable marginal cash tax rate and a beta for MRC Global, as well as certain financial metrics for the United States financial markets generally.

Goldman Sachs derived a range of illustrative EVs for MRC Global by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for MRC Global the amount of MRC Global’s net debt, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for MRC Global. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of MRC Global, as provided by and approved for Goldman Sachs’ use by the management of DNOW to derive a range of illustrative present values per share ranging from $15.60 to $19.39.

Pro Forma Combined Company. Using the DNOW Pro Forma Projections, including the Synergies, and the NOL Projections, Goldman Sachs performed an illustrative discounted cash flow analysis on the pro forma combined company to derive a range of illustrative present values per share of common stock of the pro forma combined company. Using the mid-year convention for discounting cash flows and discount rates ranging from 10.5% to 12.5%, reflecting estimates of the pro forma combined company’s weighted average cost of capital, Goldman Sachs discounted to present value as of March 31, 2025 (i) estimates of unlevered free cash flow for the pro forma combined company for the last three fiscal quarters of the fiscal year 2025 and the fiscal years 2026 through 2029 as reflected in the DNOW Pro Forma Projections, including the Synergies (taking into account the NOL Projections), and (ii) a range of illustrative terminal values for the pro forma combined company, which were calculated by applying the terminal year exit EV/EBITDA multiples ranging from 6.5x to 7.5x, to a terminal year estimate of the EBITDA to be generated by the pro forma combined company (which analysis implied perpetuity growth rates ranging from 1.3% to 4.3%), as reflected in the DNOW Pro Forma Projections, including the Synergies (taking into account the NOL Projections). The range of terminal year exit EV/EBITDA multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account historical trading multiples of DNOW and MRC Global. Goldman Sachs derived such discount rates by application of the CAPM, which requires certain company-specific inputs, including the pro forma combined company’s target capital structure weightings, the cost of long-term debt, future applicable marginal cash tax rate and a beta for the pro forma combined company, as well as certain financial metrics for the United States financial markets generally.

Goldman Sachs derived a range of illustrative EVs for the pro forma combined company by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for the pro forma combined company the amount of the pro forma combined company’s net debt and non-controlling interest, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for the pro forma combined company. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of the pro forma combined company, as provided by and approved for Goldman Sachs’ use by the management of DNOW, using the treasury stock method, to derive a range of illustrative present values per share ranging from $17.15 to $20.92.

Illustrative Present Value of Future Share Price Analysis

DNOW on a Standalone Basis. Using the DNOW Standalone Projections (taking into account the NOL Projections), Goldman Sachs performed an illustrative analysis of the implied present value of an illustrative future value per share of DNOW common stock. For this analysis, Goldman Sachs first calculated the implied EV for DNOW as of December 31 for each of fiscal years 2026 and 2027, by applying a range multiples of illustrative EV to the next twelve month (referred to as “NTM”) EBITDA (referred to as “EV/NTM EBITDA)” of 6.5x to 7.5x to estimates of DNOW’s NTM EBITDA at each exit year for each of fiscal years 2026 and 2027. This illustrative range of EV/NTM EBITDA multiple estimates was derived by Goldman Sachs utilizing its professional judgment and experience, taking into account current and historical EV/NTM EBITDA multiples for DNOW.

Goldman Sachs then subtracted the amount of DNOW’s net debt and non-controlling interest for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for DNOW for each of fiscal years 2026 and 2027. Goldman Sachs then divided these implied equity values by the projected year-end number of fully diluted outstanding shares of DNOW common stock for each of fiscal years 2026 and 2027, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of DNOW common stock. Goldman Sachs then discounted these implied future equity values per share of DNOW common stock to March 31, 2025, using an illustrative discount rate of 11.0%, reflecting an estimate of DNOW’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for DNOW, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $15.44 to $17.46 per share of DNOW common stock.

MRC Global on a Standalone Basis. Using the MRC Global Standalone Projections, Goldman Sachs performed an illustrative analysis of the implied present value of an illustrative future value per share of MRC Global common stock. For this analysis, Goldman Sachs first calculated the implied EV for MRC Global as of December 31 for each of fiscal years 2026 and 2027, by applying a range of multiples of illustrative EV/NTM EBITDA multiples of 6.5x to 7.5x to estimates of MRC Global’s NTM EBITDA at each exit year for each of the fiscal years 2026 through 2027. This illustrative range of EV/NTM EBITDA multiple estimates was derived from Goldman Sachs utilizing its professional judgment and experience, taking into account current and historical EV/NTM EBITDA multiples for MRC Global.

Goldman Sachs then subtracted the amount of MRC Global’s net debt for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for MRC Global for each of fiscal years 2026 and 2027. Goldman Sachs divided these implied equity values by the projected year-end number of fully diluted outstanding shares of MRC Global common stock for each of fiscal years 2026 and 2027, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of MRC Global common stock. Goldman Sachs then discounted these implied future equity values per share of MRC Global common stock to March 31, 2025, using an illustrative discount rate of 13.5%, reflecting an estimate of MRC Global’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for MRC Global, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $13.66 to $16.78 per share of MRC Global common stock.

Pro Forma Combined Company. Using the DNOW Pro Forma Projections, including the Synergies and taking into account the NOL Projections, Goldman Sachs performed an illustrative analysis of the implied present value of an illustrative future value per share of the pro forma combined company. For this analysis, Goldman

##### Table of Contents

Sachs first calculated the implied EV for the pro forma combined company as of December 31 for each of fiscal years 2026 and 2027, by applying a range of multiples of illustrative EV/NTM EBITDA multiples of 6.5x to 7.5x to estimates of the pro forma company’s NTM EBITDA at each exit year for each of fiscal years 2026 and 2027. This illustrative range of EV/NTM EBITDA multiple estimates was derived from Goldman Sachs utilizing its professional judgment and experience.

Goldman Sachs then subtracted the amount of the pro forma combined company’s net debt and non-controlling interest for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for the pro forma combined company for each of fiscal years 2026 and 2027. Goldman Sachs divided these implied equity values by the projected year-end number of fully diluted outstanding shares of the pro forma combined company’s common stock for each of fiscal years 2026 and 2027, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of the pro forma combined company common stock. Goldman Sachs then discounted these implied future equity values per share of the pro forma company common stock to March 31, 2025, using an illustrative discount rate of 11.5%, reflecting an estimate of the pro forma combined company’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for the pro forma combined company, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $15.97 to $19.75 per share of the pro forma combined company common stock.

Illustrative Precedent Transaction Premia Paid Analysis

Goldman Sachs reviewed and analyzed, using publicly available information, the acquisition premia for all-stock merger and acquisition transactions announced from December 31, 2020 through June 25, 2025 involving a public company based in the United States as the target where the disclosed transaction value was greater than $1 billion. For the entire period, using publicly available information, Goldman Sachs calculated the median, 25th percentile and 75th percentile premia of the price paid in the 69 transactions relative to the target’s last undisturbed closing stock price prior to announcement of the transaction. This analysis indicated a median premium of 14% across the period. This analysis also indicated a 25th percentile premium of 4% and 75th percentile premium of 27% across the period. Using this analysis, Goldman Sachs applied a reference range of illustrative premia of 4% to 27% to the undisturbed closing price per share of MRC Global common stock of $12.97 as of June 25, 2025 and calculated a range of implied equity values per share of MRC Global common stock of $13.49 to $16.47.

General

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to DNOW or MRC Global or the contemplated mergers.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs’ providing its opinion to the DNOW board as to the fairness from a financial point of view to DNOW, as of June 26, 2025, of the exchange ratio pursuant to the merger agreement. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon

98

##### Table of Contents

numerous factors or events beyond the control of the parties or their respective advisors, none of DNOW, MRC Global, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecasted.

The exchange ratio was determined through arm’s-length negotiations between DNOW and MRC Global and was approved by the DNOW board. Goldman Sachs provided advice to DNOW during these negotiations. Goldman Sachs did not, however, recommend any specific exchange ratio to DNOW or its board of directors or that any specific exchange ratio constituted the only appropriate exchange ratio for the mergers.

As described above, Goldman Sachs’ opinion to the DNOW board was one of many factors taken into consideration by the DNOW board in making its determination to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex B to this joint proxy statement/prospectus.

Goldman Sachs and its affiliates are engaged in advisory, underwriting, lending and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of DNOW, MRC Global and any of their respective affiliates and third parties or any currency or commodity that may be involved in the mergers. Goldman Sachs Investment Banking has an existing lending relationship with MRC Global and/or its subsidiaries. Goldman Sachs acted as financial advisor to DNOW in connection with, and participated in certain of the negotiations leading to, the mergers. At DNOW’s request, at the time of the execution of the merger agreement, an affiliate of Goldman Sachs entered into financing commitments to provide DNOW with a backstop to the accordion of DNOW’s existing asset based loan in connection with the consummation of the mergers, subject to the terms of such commitments (the “Backstop”). The actual amount of aggregate fees received by Goldman Sachs and its affiliates in connection with the Backstop will depend upon, among other things, the timing of such commitments. DNOW estimates that Goldman Sachs and its affiliates will in the aggregate receive approximately $2.5 million in fees in connection with the Backstop. During the two-year period ended June 26, 2025, Goldman Sachs Investment Banking has not been engaged by DNOW or its affiliates to provide financial advisory or underwriting services for which Goldman Sachs has recognized compensation. Goldman Sachs has provided certain financial advisory and/or underwriting services to MRC Global and/or its affiliates from time to time for which Goldman Sachs Investment Banking has received, and may receive, compensation, including having acted as documentation agent in connection with a Term Loan B offering for MRC Global in November 2024. During the two-year period ended June 26, 2025, Goldman Sachs has recognized compensation for financial advisory and/or underwriting services provided by Goldman Sachs Investment Banking to MRC Global and/or its affiliates of approximately $196,000. Goldman Sachs may also in the future provide financial advisory and/or underwriting services to DNOW, MRC Global and their respective affiliates for which Goldman Sachs Investment Banking may receive compensation.

The DNOW board selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the mergers. Pursuant to a letter agreement dated December 2, 2024, DNOW engaged Goldman Sachs to act as its financial advisor in connection with the contemplated mergers. The engagement letter between DNOW and Goldman Sachs provides for a transaction fee that is estimated, based on the information available as of the date of announcement, at approximately $19 million, $3 million of which became payable upon the announcement of the mergers, and the remainder of which is contingent upon consummation of the mergers. Goldman Sachs may receive an additional fee of up to $3 million at DNOW’s sole discretion. In addition, DNOW has agreed to reimburse Goldman Sachs for certain of its expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Opinion of MRC Global’s Financial Advisor

Pursuant to an engagement letter, MRC Global retained J.P. Morgan as its financial advisor in connection with the mergers.

At the meeting of the MRC Global board on June 26, 2025, J.P. Morgan rendered its oral opinion to the MRC Global board to the effect that, as of such date, and based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the review that J.P. Morgan undertook in preparing its opinion, the exchange ratio in the proposed First Merger was fair, from a financial point of view, to the MRC Global stockholders. J.P. Morgan confirmed its June 26, 2025 oral opinion by delivering its written opinion, dated as of June 26, 2025, to the MRC Global board that, as of such date, the exchange ratio in the proposed First Merger was fair, from a financial point of view, to the MRC Global stockholders.

The full text of the written opinion of J.P. Morgan, dated as of June 26, 2025, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review that J.P. Morgan undertook in preparing its opinion, is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference. The summary of J.P. Morgan’s opinion set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. The MRC Global stockholders are urged to read the opinion in its entirety. J.P. Morgan’s written opinion was addressed to the MRC Global board (in its capacity as such) in connection with and for the purposes of its evaluation of the mergers, and was limited to the fairness, from a financial point of view, of the exchange ratio to the MRC Global stockholders in the proposed First Merger and did not address any other aspect of the mergers. J.P. Morgan expressed no opinion as to the fairness of any consideration to be paid in connection with the mergers to the holders of any other class of securities, creditors or other constituencies of MRC Global or as to the underlying decision by MRC Global to engage in the mergers. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any stockholder of MRC Global as to how such stockholder should vote with respect to the mergers or any other matter.

In arriving at its opinion, J.P. Morgan, among other things:

| • |  | reviewed the merger agreement;

| • |  | reviewed certain publicly available business and financial information concerning MRC Global and DNOW and the industries in which they operate;

| • |  | compared the financial and operating performance of MRC Global and DNOW with publicly available information concerning certain other companies J.P. Morgan deemed relevant and reviewed the current and historical market prices of MRC Global common stock and DNOW common stock and certain publicly traded securities of such other companies;

| • |  | reviewed the MRC Global Projections for MRC Global and the MRC Global Projections for DNOW, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the mergers (the “Synergies”); and

| • |  | performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.

In addition, J.P. Morgan held discussions with certain members of the management of MRC Global and DNOW with respect to certain aspects of the mergers, and the past and current business operations of MRC Global and DNOW, the financial condition and future prospects and operations of MRC Global and DNOW, the effects of the mergers on the financial condition and future prospects of MRC Global and DNOW, and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or that MRC Global and DNOW furnished to or discussed with J.P. Morgan or that

was otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not independently verify any such information or its accuracy or completeness and, pursuant to J.P. Morgan’s engagement letter with MRC Global, J.P. Morgan did not assume any obligation to undertake any such independent verification. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did J.P. Morgan evaluate the solvency of MRC Global or DNOW under any applicable laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to J.P. Morgan or derived therefrom, including the Synergies, J.P. Morgan assumed that they were reasonably prepared based on assumptions reflecting management’s best currently available estimates and judgments as to the expected future results of operations and financial condition of MRC Global and DNOW to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. J.P. Morgan also assumed that the mergers and the other transactions contemplated by the merger agreement will qualify as a tax-free reorganization for United States federal income tax purposes and will be consummated as described in the merger agreement. J.P. Morgan also assumed that the representations and warranties that MRC Global, DNOW, the Merger Sub and the LLC Sub made in the merger agreement and the related agreements were and will be true and correct in all respects material to its analysis. J.P. Morgan is not a legal, regulatory or tax expert and relied on the assessments that advisors to MRC Global made with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the mergers will be obtained without any adverse effect on MRC Global or DNOW or on the contemplated benefits of the mergers.

The MRC Global Projections for MRC Global and the MRC Global Projections for DNOW furnished to J.P. Morgan were prepared by MRC Global management, with the MRC Global Projections for DNOW generally derived from the information provided by DNOW management, as discussed more fully in the section entitled “— Certain Unaudited Prospective Financial and Operating Information” beginning on page 86 of this joint proxy statement/prospectus. MRC Global does not publicly disclose internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the mergers, and MRC Global did not prepare these projections with a view toward public disclosure. These projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of MRC Global management, including, without limitation, factors related to general economic and competitive conditions, prevailing interest rates and other factors as set forth in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 43 of this joint proxy statement/prospectus. Accordingly, actual results could vary significantly from those set forth in the projections. For more information regarding the use of projections and other forward-looking statements, please refer to the section entitled “—MRC Global Forecasted Financial Information” beginning on page 89 of this joint proxy statement/prospectus.

J.P. Morgan’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of its opinion. J.P. Morgan’s opinion noted that subsequent developments may affect J.P. Morgan’s opinion and that J.P. Morgan does not have any obligation to update, revise or reaffirm its opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, to MRC Global stockholders of the exchange ratio in the proposed First Merger, and J.P. Morgan expressed no opinion as to the fairness of any consideration to be paid in connection with the mergers to the holders of any other class of securities, creditors or other constituencies of MRC Global or as to MRC Global’s underlying decision to engage in the mergers. Furthermore, J.P. Morgan also expressed no opinion with respect to the amount or nature of any compensation to any officers, directors or employees of any party to the mergers, or any class of such persons relative to the exchange ratio in the mergers or with respect to the fairness of any compensation. J.P. Morgan expressed no opinion as to the price at which MRC Global common stock or DNOW common stock will trade at any future time.

J.P. Morgan’s opinion noted that J.P. Morgan was not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of MRC Global or any other alternative transaction.

##### Table of Contents

The terms of the merger agreement, including the exchange ratio, were determined through arm’s length negotiations between MRC Global and DNOW, and the decision to enter into the merger agreement was solely that of the MRC Global board and the DNOW board. J.P. Morgan’s opinion and financial analyses were only one of the many factors that the MRC Global board considered in its evaluation of the mergers and should not be viewed as determinative of the views of the MRC Global board or management with respect to the mergers or the exchange ratio.

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methodologies in rendering its opinion to the MRC Global board on June 26, 2025 and in the financial analyses presented to the MRC Global board on such date in connection with the rendering of J.P. Morgan’s opinion. The following is a summary of the material financial analyses that J.P. Morgan utilized in connection with rendering its opinion to the MRC Global board and does not purport to be a complete description of the analyses or data that J.P. Morgan presented. Some of the summaries of the financial analyses include information presented in tabular format. The tables are not intended to stand alone, and to more fully understand the financial analyses that J.P. Morgan used, the tables must be read together with the full text of each summary. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s analyses.

Public Trading Multiples. Using publicly available information, J.P. Morgan compared selected financial data of each of MRC Global and DNOW with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be sufficiently analogous to those engaged in by MRC Global and DNOW (or aspects thereof), as applicable.

The companies selected by J.P. Morgan with respect to MRC Global were as follows:

| • |  | DNOW

| • |  | DXP Enterprises, Inc.

| • |  | WESCO International, Inc.

| • |  | Rexel S.A.

The companies selected by J.P. Morgan with respect to DNOW were as follows:

| • |  | MRC Global

| • |  | DXP Enterprises, Inc.

| • |  | WESCO International, Inc.

| • |  | Rexel S.A.

J.P. Morgan selected these companies because, among other reasons, they are publicly traded companies with operations and businesses that, for the purposes of J.P. Morgan’s analysis, J.P. Morgan considered to be similar to those of MRC Global and DNOW, as applicable. However, certain of these companies may have characteristics that are materially different from those of MRC Global and DNOW, as applicable. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the selected companies differently than they would affect MRC Global or DNOW, as applicable.

Using publicly available information, J.P. Morgan calculated, for each selected company,

| (i) | the multiple of the firm value (calculated as equity value, plus or minus, as applicable, net debt or net cash, the “FV”) to the analyst consensus estimates of fiscal year 2025 adjusted EBITDA for the applicable company (the “FV / 2025E Adj. EBITDA Multiple”) and

102

##### Table of Contents

| (ii) | the multiple of the FV to the analyst consensus estimates of fiscal year 2026 adjusted EBITDA for the applicable company (the “FV/2026E Adj. EBITDA Multiple”).

| For | MRC Global, based on the results of this analysis, J.P. Morgan selected

| (i) | a FV/2025E Adj. EBITDA Multiple reference range of 7.00x to 9.25x and applied such reference range to MRC Global’s projected pre-SBC adjusted EBITDA for fiscal year 2025 and

| (ii) | a FV/2026E Adj. EBITDA Multiple reference range for MRC Global of 6.50x to 8.50x and applied such reference range to MRC Global’s projected pre-SBC adjusted EBITDA for fiscal year 2026, in each case as provided in the MRC Global Projections for MRC Global.

The analysis derived the following ranges of implied equity value per share of MRC Global common stock (rounded to the nearest $0.10):

Metric |  | Implied Equity Value Per Share |
| Low |  |  | High |
FV/2025E Pre-SBC Adj. EBITDA Multiple |  | $ | 12.90 |  |  | $ | 18.30 |
FV/2026E Pre-SBC Adj. EBITDA Multiple |  | $ | 12.80 |  |  | $ | 17.90 |

J.P. Morgan compared these ranges to:

| (i) | the price per share of MRC Global common stock of $12.97 as of June 25, 2025; and

| (ii) | the implied price per share of MRC Global common stock of $13.85 based on the exchange ratio.

For DNOW, based on the results of this analysis, J.P. Morgan selected

| (i) | a FV/2025E Adj. EBITDA Multiple reference range of 7.00x to 9.25x and applied such reference range to DNOW’s projected pre-SBC adjusted EBITDA for fiscal year 2025 and

| (ii) | a FV/2026E Adj. EBITDA Multiple reference range for DNOW of 6.50x to 8.50x and applied such reference range to DNOW’s projected pre-SBC adjusted EBITDA for fiscal year 2026, in each case as provided in the MRC Global Projections for DNOW. The analysis derived the following ranges of implied equity value per share of DNOW common stock (rounded to the nearest $0.10):

Metric |  | Implied Equity Value Per Share |
| Low |  |  | High |
FV/2025E Pre-SBC Adj. EBITDA Multiple |  | $ | 14.60 |  |  | $ | 18.70 |
FV/2026E Pre-SBC Adj. EBITDA Multiple |  | $ | 14.60 |  |  | $ | 18.60 |

J.P. Morgan compared these ranges to the price per share of DNOW common stock of $14.60 as of June 25, 2025.

Discounted Cash Flow Analysis. J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining an implied fully diluted equity value per share for MRC Global common stock and DNOW common stock. J.P. Morgan calculated the unlevered free cash flows that each of MRC Global and DNOW are expected to generate during fiscal years 2025 through 2031 based on the MRC Global Projections for MRC Global and MRC Global Projections for DNOW, as applicable, as discussed more fully in the section entitled “—MRC Global Forecasted Financial Information” beginning on page 89 of this joint proxy statement/prospectus. J.P. Morgan also calculated a range of terminal values for each of MRC Global and DNOW at the end of this period by applying terminal growth rates ranging from 1.00% to 2.00%, based on guidance that MRC Global management provided, to estimates of terminal unlevered free cash flows for each of MRC Global and DNOW at the end of fiscal year 2031, as provided in the MRC Global Projections for MRC Global and MRC Global Projections for DNOW, as applicable.

##### Table of Contents

J.P. Morgan then discounted the unlevered free cash flow estimates and the range of terminal values to present value as of June 30, 2025 using discount rates ranging from 8.50% to 10.50%, which range J.P. Morgan chose based upon an analysis of the weighted average cost of capital of each of MRC Global and DNOW. The present values of the unlevered free cash flow estimates and the range of terminal values were then adjusted for each of MRC Global’s and DNOW’s estimated net debt as of June 30, 2025, as provided in the MRC Global Projections for MRC Global and MRC Global Projections for DNOW in each case discounted to present value as of June 30, 2025 using a range of discount rates from 8.50% to 10.50%.

This analysis indicated a range of implied per share equity value for MRC Global common stock (rounded to the nearest $0.10) of approximately $14.50 to $22.30, which J.P. Morgan compared to:

| (i) | the price per share of MRC Global common stock of $12.97 as of June 25, 2025; and

| (ii) | the implied price per share of MRC Global common stock of $13.85 based on the exchange ratio.

This analysis also indicated a range of implied per share equity value for DNOW common stock (rounded to the nearest $0.10) of approximately $15.80 to $21.90, which J.P. Morgan compared to the price per share of DNOW common stock of $14.60 as of June 25, 2025.

Implied Relative Value Analysis. J.P. Morgan compared the results for MRC Global to the results for DNOW with respect to the public trading multiples and discounted cash flow analyses described above. J.P. Morgan compared the lowest implied equity value per share of MRC Global to the highest implied equity value per share of DNOW to derive the lowest exchange ratio that each pair of results implied. J.P. Morgan also compared the highest implied equity value per share of MRC Global to the lowest implied equity value per share of DNOW to derive the highest exchange ratio that each pair of results implied. The ranges of implied exchange ratios resulting from this analysis were as follows:

|  | Implied Exchange Ratios |
Metric |  | Low |  |  | High |
FV/2025E Adj. EBITDA Multiple |  |  | 0.6903x |  |  |  | 1.2507x |
FV/2026E Adj. EBITDA Multiple |  |  | 0.6881x |  |  |  | 1.2206x |
Discounted Cash Flow |  |  | 0.6588x |  |  |  | 1.4133x |

The ranges of implied exchange ratios resulting from the foregoing analysis were compared to:

| (i) | the exchange ratio of 0.8884x as of June 25, 2025, the last trading day prior to the date of the written opinion, dated as of June 26, 2025; and

| (ii) | the exchange ratio of 0.9489x, as contemplated in the proposed First Merger.

Value Creation Analysis. J.P. Morgan conducted an analysis of the theoretical value creation to the existing MRC Global stockholders that compared the estimated implied equity value of MRC Global on a standalone basis, based on the midpoint value determined in J.P. Morgan’s discounted cash flow analysis described above, to the estimated implied equity value of the existing MRC Global stockholders’ ownership in the combined company, pro forma for the mergers.

J.P. Morgan calculated the implied equity value of the existing MRC Global stockholders’ ownership in the combined company, pro forma for the mergers, by

| (i) | adding the sum of:

| (a) | the implied equity value of MRC Global on a standalone basis of approximately $1,547 million, using the midpoint value determined in J.P. Morgan’s discounted cash flow analysis of MRC Global described above;

104

##### Table of Contents

| (b) | the implied equity value of DNOW on a standalone basis of approximately $1,981 million, using the midpoint value determined in J.P. Morgan’s discounted cash flow analysis of DNOW described above; and

| (c) | the estimated value of Synergies, as MRC Global management estimated and provided to J.P. Morgan for use in connection with its analysis, in the aggregate amount of $495 million:

| (ii) | subtracting certain other expenses, as MRC Global management estimated and provided to J.P. Morgan for use in connection with its analysis; and

| (iii) | multiplying such result by the pro forma equity ownership of the combined company by the existing MRC Global stockholders.

This analysis indicated an implied pro forma equity value for the combined company of approximately $3,948 million and an implied pro forma equity value for the existing MRC Global stockholders’ ownership of the combined company of approximately $1,715 million, which represents accretion in value of 10.9% compared to the equity value of the MRC Global stockholders’ ownership of MRC Global on a standalone basis. There can be no assurance, however, that the Synergies, transaction-related expenses and other impacts referred to above will not be substantially greater or less than those MRC Global’s management estimated and described above.

Miscellaneous. The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data that J.P. Morgan presented. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and J.P. Morgan’s opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above were merely utilized to create points of reference for analytical purposes and should not be taken to be the view of J.P. Morgan with respect to the actual value of MRC Global or DNOW. The order of analyses described does not represent the relative importance or weight that J.P. Morgan gave to those analyses. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors that J.P. Morgan considered, and J.P. Morgan did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion.

Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses that J.P. Morgan used or made are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be acquired or sold. None of the selected companies reviewed as described in the above summary is identical to MRC Global or DNOW. However, the companies selected were chosen by J.P. Morgan because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of MRC Global and DNOW. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to MRC Global and DNOW.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. J.P. Morgan was selected to advise MRC Global with respect to the mergers and deliver an opinion to the MRC Global board with respect to the mergers on the basis of, among other things, such experience, its qualifications and reputation in connection with such matters and its familiarity with MRC Global, DNOW and the industries in which they operate.

105

##### Table of Contents

For financial advisory services rendered in connection with the mergers, MRC Global has agreed to pay J.P. Morgan an estimated fee of approximately $23 million, $3 million of which became payable to J.P. Morgan at the time J.P. Morgan delivered its opinion and the remainder of which is contingent and payable upon the consummation of the mergers. In addition, MRC Global has agreed to reimburse J.P. Morgan for certain of its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities arising out of J.P. Morgan’s engagement.

During the two years preceding the date of J.P. Morgan’s opinion, neither J.P. Morgan nor its affiliates have had any material financial advisory or other material commercial or investment banking relationships with DNOW. During the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates have had and continue to have commercial or investment banking relationships with MRC Global for which J.P. Morgan and its affiliates have received customary compensation. Such services during such period have included acting as joint lead arranger and joint bookrunner on a credit facility in November 2024. In addition, J.P. Morgan’s commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of MRC Global, for which it receives customary compensation or other financial benefits. During the two-year period preceding delivery of its opinion on June 26, 2025, the aggregate fees that J.P. Morgan recognized from MRC Global were approximately $6 million. In addition, J.P. Morgan and its affiliates hold, on a proprietary basis, less than 1% of the outstanding MRC Global common stock and DNOW common stock. In the ordinary course of their businesses, J.P. Morgan and its affiliates actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of MRC Global or DNOW for their own accounts or for the accounts of customers and, accordingly, they likely at any time hold long or short positions in such securities or other financial instruments.

Interests of Certain DNOW Directors and Executive Officers in the Mergers

When considering the recommendation of the DNOW board that DNOW stockholders vote “FOR” the DNOW stock issuance proposal and, if necessary, “FOR” the DNOW adjournment proposal, DNOW stockholders should be aware that certain of DNOW’s directors and executive officers have interests in the mergers that are different from, or in addition to, the interests of other DNOW stockholders generally. The DNOW board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that DNOW stockholders vote “FOR” the DNOW stock issuance proposal and, if necessary, “FOR” the DNOW adjournment proposal. Such interests include that certain, if not all, of the current directors and executive officers of DNOW are expected to continue as directors and executive officers of DNOW following consummation of the mergers.

The mergers do not constitute a “change in control” for purposes of the DNOW executives’ or non-employee directors’ equity award arrangements. Accordingly, there are no payments or benefits to DNOW NEOs that are based on or otherwise relate to the mergers. Upon completion of the mergers, certain, if not all, of the current executive officers of DNOW and all members of DNOW’s board of directors are expected to continue in their current roles with the combined company, as described in “—Board of Directors and Management of DNOW Following Completion of the Mergers.”

Interests of Certain MRC Global Directors and Executive Officers in the Mergers

In considering the recommendations of the MRC Global board, MRC Global stockholders should be aware that MRC Global’s executive officers have interests in the mergers, including financial interests, which may be different from, or in addition to, the interests of the other MRC Global stockholders generally. These interests include the following and are more fully summarized as follows:

| • |  | MRC Global directors’ unvested shares of MRC Global restricted shares and MRC Global executive officers’ unvested MRC Global RSUs and MRC Global PSUs will either accelerate upon the mergers or will accelerate upon a qualifying termination following the mergers;

106

##### Table of Contents

| • |  | Employment agreements and separation policies provide for certain severance protections upon a qualifying termination;

| • |  | The Omnibus Amendments (defined below) with each of Daniel J. Churay, Grant Bates, John P. McCarthy, Emily Shields, Shweta Kurvey-Mishra and Victor Clark provide for an extension of the post-termination restricted period under the applicable award agreements;

| • |  | The McCarthy Bonus Letter (defined below) issued to Mr. McCarthy provides for a special cash bonus payable on or before closing of the mergers;

| • |  | The Anderson Bonus Letter (defined below) issued to Gillian Anderson provides for a cash bonus that may be accelerated on the closing of the mergers; and

| • |  | MRC Global’s directors and executive officers are entitled to continued indemnification as provided for in the merger agreement and further described in “The Merger Agreement — Indemnification and Insurance.”

The members of the MRC Global board were aware of, and considered, these interests, among other matters, in evaluating the merger agreement, in approving the merger agreement and in determining to recommend that MRC Global stockholders approve the proposals presented at the MRC Global special meeting.

The following discussion sets forth certain of these interests in the mergers of each person who has served as an executive officer or non-employee director of MRC Global since January 1, 2024.

Treatment of MRC Global Equity Awards in the Mergers

The merger agreement provides that, at the Effective Time, each MRC Global restricted share that is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, immediately vest with respect to 100% of the MRC Global restricted shares, which MRC Global restricted shares will be converted into the right to receive

(A) the merger consideration with respect to each share of MRC Global common stock and

(B) an amount in cash equal to the accrued but unpaid dividends with respect to such MRC Global restricted shares,

in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, at the Effective Time, each MRC Global RSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, immediately vest with respect to 100% of the shares of MRC Global common stock subject to that MRC Global RSU, which shares of MRC Global common stock will be converted into the right to receive

(A) the merger consideration with respect to each share of MRC Global common stock, reduced by the number of shares of DNOW common stock required or permitted to be deducted to satisfy applicable withholding and similar taxes and

(B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such MRC Global RSU, if any, less applicable withholding and similar taxes,

in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, at the Effective Time, each outstanding MRC Global RSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will be canceled and converted into an award of DNOW RSUs in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of

107

##### Table of Contents

(A) the total number of shares of MRC Global common stock subject to that award of MRC Global RSUs immediately prior to the Effective Time multiplied by

(B) the exchange ratio.

Those DNOW RSUs will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding MRC Global RSU award agreement (except that the award will be payable in DNOW common stock).

The merger agreement also provides that, at the Effective Time, each MRC Global PSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, be canceled, and the holder thereof will then become entitled to receive, in full satisfaction of the rights of the holder with respect thereto, the number of shares of MRC Global common stock (rounded to the nearest share) subject to the MRC Global PSU, which shares of MRC Global common stock will be converted into the right to receive

(A) the merger consideration with respect to each share of MRC Global common stock subject to the MRC Global PSU that vest based on the determination of performance set forth in the applicable award agreement, reduced by the number of shares of DNOW common stock required or permitted to be deducted to satisfy applicable withholding and similar taxes and

(B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such MRC Global PSU, if any, less applicable withholding and similar taxes,

in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, at the Effective Time, each outstanding MRC Global PSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will be canceled and converted into a DNOW RSU in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of

(A) the number of shares of MRC Global common stock subject to such MRC Global PSU immediately prior to the Effective Time that vest based on the determination of performance set forth in the applicable award agreement multiplied by

(B) the exchange ratio.

Those DNOW RSUs will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in DNOW common stock and the award will no longer be subject to performance metrics). For purposes of the immediately preceding sentence, the number of shares of MRC Global common stock subject to the MRC Global PSU will be deemed to be the number of shares subject to the MRC Global PSU with performance deemed achieved, except as previously disclosed to DNOW, in accordance with the terms and conditions of the applicable award agreement governing the MRC Global PSU immediately prior to the Effective Time.

To the extent that any award described herein constitutes nonqualified deferred compensation subject to Section 409A of the Code, any payment contemplated hereby with respect to such award will be made in accordance with the merger agreement and the applicable award’s terms or, if later, at the earliest time permitted under the terms of such award that will not result in the application of a tax or penalty under Section 409A of the Code.

Table of Security Holdings

The following table below sets forth, as of July 15, 2025, for each person who has served as a director or executive officer of MRC Global since the beginning of MRC Global’s last fiscal year

(A) the aggregate number of shares of MRC Global restricted shares,

(B) the aggregate number of shares subject to outstanding MRC Global RSUs and

(C) the aggregate number of shares subject to outstanding MRC Global PSUs.

The values are calculated assuming that the merger consideration is $13.95 per share, determined by multiplying the exchange ratio of 0.9489 by $14.70, which represents the average closing price of a share of DNOW’s common stock over the first five business days following the first public announcement of the mergers on June 26, 2025. The actual value realized with respect to any shares of MRC Global restricted shares, MRC Global RSUs and MRC Global PSUs cannot be determined with any certainty until the awards vest or are settled, as applicable. None of the directors or executive officers set forth in the table below hold directly or indirectly any stock options or warrants to purchase shares of MRC Global common stock.

MRC Global Executive Officer Severance Arrangements

Each of Robert J. Saltiel, Jr. and Kelly Youngblood have entered into an employment agreement with MRC Global (the “Employment Agreements”). Under the Employment Agreements, if upon a Change in Control, or within 24 months following a Change in Control, MRC Global terminates the executive officer’s employment other than for “Cause,” death or “Disability,” or the executive officer leaves employment for “Good Reason,” Messrs. Saltiel and Youngblood will be entitled to the following:

| • |  | All accrued, but unpaid obligations (including, salary, unpaid annual cash incentive for completed periods, expense reimbursement and vacation pay);

| • |  | A separation payment in an amount equal to the sum of three times (for Mr. Saltiel) and two times (for Mr. Youngblood) the sum of base salary plus target annual cash incentive, as in effect on the date of termination;

| • |  | A pro-rata annual cash incentive for the fiscal year in which termination occurs based on the greater of target or actual performance through the end of the fiscal year; and

| • |  | Medical Continuation for 36 months (for Mr. Saltiel) and 24 months (for Mr. Youngblood).

Each of their respective Employment Agreements define the terms “Change in Control,” “Cause,” “Disability,” “Good Reason” and “Medical Continuation.”

None of the other executive officers are subject to an employment agreement. However, each executive officer (other than Messrs. Saltiel and Youngblood) may receive certain severance payments and benefits following a termination of employment under certain circumstances pursuant to MRC Global’s Executive

Separation Policy (the “Executive Separation Policy”) or MRC Global’s Vice President Change in Control Separation Policy (the “Vice President Separation Policy” and together with the Executive Separation Policy, the “Separation Policies”). Under the applicable Separation Policy, if upon a Change in Control, or within 24 months following a Change in Control, the employment of Messrs. Churay, Bates, Clark, McCarthy or Smith, or Mses. Kurvey-Mishra, Anderson and Shields is terminated by MRC Global other than for “Cause,” death or “Disability,” or by any of them for “Good Reason,” the terminated executive officer will be entitled to the following:

| • |  | All accrued, but unpaid obligations (including, salary, unpaid annual cash incentive for completed periods, expense reimbursement and vacation pay);

| • |  | Payment of an amount equal to two times (for Mr. Churay), 1.5 times (for Messrs. Bates, Clark, McCarthy and Smith, and Mses. Kurvey-Mishra and Shields) the sum of base salary plus target annual cash incentive, or 1 times (for Ms. Anderson) base salary, in each case, as in effect on the date of termination;

| • |  | A pro-rata annual cash incentive for the fiscal year in which termination occurs based on the greater of target or actual performance through the end of the fiscal year; and

| • |  | Medical Continuation for 24 months (for Mr. Churay), 18 months (for Messrs. Bates, Clark, McCarthy and Smith, and Mses. Kurvey-Mishra and Shields) or 12 months (for Ms. Anderson).

Each applicable Separation Policy defines the terms “Change in Control,” “Cause,” “Disability,” “Good Reason” and “Medical Continuation.”

The MRC Global RSU award agreements and the MRC Global PSU award agreements under which MRC Global has granted the applicable awards contain provisions providing for:

(A) continued vesting upon retirement and

(B) accelerated vesting upon

(i) the death or disability of the executive officer or

(ii) for awards on or after February 2024, upon termination of employment by MRC Global without cause or termination of employment by the executive officer for “good reason,” in each case, following a change in control of MRC Global or

(iii) for awards prior to February 2024, upon a change in control.

The mergers constitute such a change in control.

For an estimate of the value of the severance payments and benefits described above that would become payable to each of our NEOs upon a severance-qualifying termination, see “— Quantification of Potential Payments and Benefits to MRC Global’s Named Executive Officers in Connection with the Mergers” below.

Omnibus Amendments and Transaction Bonuses

On June 26, 2025, in connection with the mergers, MRC Global entered into an omnibus amendment (collectively, the “Omnibus Amendments”) with each of

Bates, Clark and McCarthy and Mses. Kurvey-Mishra and Shields’ non-competition covenants, from twelve to eighteen months.

On June 24, 2025, MRC Global issued a letter to Mr. McCarthy that provides for a $150,000 cash bonus (the “McCarthy Bonus Letter”), payable in two equal installments. The first installment was paid on the first payroll date following the date of the McCarthy Bonus Letter, and the second installment will be paid on the earlier of the mergers or May 1, 2026, subject generally to Mr. McCarthy’s continued employment through the payment date of the second installment.

On April 30, 2025, MRC Global issued a letter to Ms. Anderson that provides for a $60,000 cash bonus (the “Anderson Bonus Letter”), payable in installments and subject to the completion of certain goals. Pursuant to the Anderson Bonus Letter, if Ms. Anderson is terminated without Cause, leaves for Good Reason or leaves employment due to her death or Disability or a Change in Control occurs, any unpaid installments will become due and payable to Ms. Anderson or her estate, as the case may be.

New Management Arrangements

As of the date of this joint proxy statement/prospectus, there are no other new employment, equity contribution or other agreements between any MRC Global executive officer or director, on the one hand, and MRC Global or DNOW, on the other hand. Prior to and following the closing of the mergers, however, certain of our executive officers may have discussions with, and may enter into agreements with, DNOW, the surviving corporation or their affiliates regarding employment with or providing consultation services to DNOW, the surviving corporation or their affiliates or the right to participate in the equity of the surviving corporation or one or more of its affiliates to be effective following the closing of the mergers.

Quantification of Potential Payments and Benefits to MRC Global’s Named Executive Officers in Connection with the Mergers

This section sets forth the information that Item 402(t) of Regulation S-K requires regarding the compensation of each of MRC Global’s NEOs that is based on or otherwise relates to the mergers and that will or may become payable to MRC Global’s NEOs at the consummation of the mergers or upon a qualifying termination of employment that occurs during the protection period, assuming the following:

| (1) | the closing occurs on July 15, 2025 (which is the assumed date solely for purposes of the compensation disclosure in this section),

| (2) | each of the MRC Global NEOs experiences a termination without Cause or leaves for Good Reason on that date pursuant to the applicable Employment Agreement or Separation Policy,

| (3) | the MRC Global NEOs’ respective base salaries and target annual bonuses remain unchanged from those that were in effect as of the date of this filing,

| (4) | MRC Global RSUs and MRC Global PSUs that the NEOs hold are outstanding as of the date hereof do not otherwise vest prior to the completion of the mergers, except with respect to regularly scheduled vesting dates occurring prior to the assumed closing date of July 15, 2025,

112

##### Table of Contents

| (5) | for purposes of determining the value of MRC Global RSUs and MRC Global PSUs, the value of the merger consideration is $13.95 per share, determined by multiplying the exchange ratio of 0.9489 by $14.70, which represents the average closing price of a share of DNOW common stock over the first five business days following the first public announcement of the mergers on June 26, 2025,

| (6) | the number of shares that vest pursuant to MRC Global PSUs was calculated in accordance with footnote (1) to the table above entitled “Table of Security Holdings,”

| (7) | no MRC Global NEO receives any additional equity grants prior to completion of the mergers, and

| (8) | each MRC Global NEO has properly executed any required releases and complied with all requirements (including any applicable restrictive covenants) necessary to receive the payments and benefits described below. Some of the assumptions used in the table below are based upon information not currently available and, as a result, the actual amounts to be received by any of the individuals below may materially differ from the amounts set forth below.

The payments described in the table below are made pursuant to the arrangements described above in the section entitled “Interests of Certain MRC Global Directors and Executive Officers in the Mergers.”

(1) | Amounts reflect the severance payments provided under the Employment Agreements or the Executive Separation Policy, as applicable, as described above in the section entitled “— MRC Global Executive Officer Severance Arrangements.” The amounts included in this column are considered to be “double-trigger” payments, which means that both a change in control of MRC Global, such as the mergers, and a qualifying termination of employment must occur during the “protection period,” which period extends from the date of the change in control until the date that is 24 months following the occurrence of a change in control, prior to any payment being provided to the applicable MRC Global NEO. Below table shows the breakdown of the cash payment including the pro-rata incentive and the separation payment for each NEO.

MRC Global Named Executive Officer |  | Pro-Rata Incentive ($) |  |  | Separation Payment ($) |

##### Table of Contents

(2) | Amounts reflect the sum of the potential value that each NEO could receive in connection with accelerated vesting and settlement of unvested MRC Global RSUs and MRC Global PSUs plus the value of accrued and unpaid dividends thereon, as more fully described above under “— Treatment of MRC Global Equity Awards in the Mergers.” There have been no dividends declared on MRC Global’s common stock. These amounts were calculated as described in footnotes (1) and (2) to the table in that section entitled “Table of Security Holdings.” The amounts in this column attributable to MRC Global RSUs and MRC Global PSUs granted in 2023 are considered to be “single-trigger,” which means that only a change in control of MRC Global, such as the mergers, must occur prior to any payment being provided to the MRC Global NEOs. The amounts in this column attributable to MRC Global RSUs and MRC Global PSUs granted in 2024 and 2025 are considered to be “double-trigger,” which means that both a change in control of MRC Global, such as the mergers, and a qualifying termination of employment must occur during the “protection period,” which, for the MRC Global RSUs and MRC Global PSUs granted in 2024 and 2025, is the period any time after the change in control, prior to any payment being provided to the applicable MRC Global NEO.

(3) | Amounts reflect the total estimated value of health and welfare coverage (which include medical and dental coverage) paid by (or reimbursed by) MRC Global that are the same or equivalent amount the NEO received prior to the termination of employment under the applicable Employment Agreements or Separation Policy. See “— MRC Global Executive Officer Severance Arrangements.” These benefits are “double-trigger.”

(4) | The amount reflects a cash bonus under the McCarthy Bonus Letter, payable in two equal installments. The first installment was previously paid and was not contingent upon a change in control. The second installment is paid on the earlier of the closing or May 1, 2026, subject generally to Mr. McCarthy’s continued employment through the payment date of the second installment, and the second installment is “single-trigger.”

(5) | The Employment Agreements and the Separation Policies provide that golden parachute payments will be paid in full or reduced to fall within the safe harbor amount provided under Section 280G of the Code, whichever will provide a better net after-tax position for a participant. For the purposes of this disclosure, the maximum amount potentially payable to each NEO in connection with the mergers is reflected even though such maximum amounts could be reduced pursuant to the cutback language included in the Employment Agreements and the Separation Policies.

(6) | Mr. Long retired as Senior Vice President – Marketing Strategy in May 2025. Due to his retirement, he will continue to vest in certain unvested MRC Global RSUs and MRC Global PSUs in accordance with his award agreements. His 2023 MRC Global RSUs and 2023 MRC Global PSUs will vest upon closing. His 2024 MRC Global RSUs and 2024 Global PSUs will vest in accordance with his award agreements.

Board of Directors and Management of DNOW Following Completion of the Mergers

Upon the completion of the mergers, David Cherechinsky, Chief Executive Officer of DNOW, and the current members of the DNOW board, will continue to serve as Chief Executive Officer and directors of the combined company, respectively. The other executive officers of DNOW are also expected to continue in their current roles with the combined company.

The merger agreement provides that, upon consummation of the mergers, DNOW’s board of directors shall be comprised of ten directors, including two directors selected from MRC Global’s board of directors by DNOW prior to closing. On July 17, 2025, DNOW notified MRC Global that DNOW had selected George J. Damiris and Ronald L. Jadin to be appointed to the DNOW board effective immediately upon closing.

Material U.S. Federal Income Tax Consequences of the Mergers

The following is a general discussion of the material U.S. federal income tax consequences to U.S. holders (as defined below) of MRC Global common stock who exchange their shares of MRC Global common stock for shares of DNOW common stock (and cash in lieu of fractional shares of DNOW common stock, if any) pursuant to the mergers. The following discussion is based on the provisions of the Code, U.S. Treasury regulations

114

##### Table of Contents

promulgated thereunder, judicial interpretations thereof and published rulings and other positions of the Internal Revenue Service (the “IRS”), each as in effect as of the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect. Any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth herein. The U.S. federal income tax laws are complex and subject to varying interpretation. Neither DNOW nor MRC Global has sought, nor intends to seek, any ruling from the IRS with respect to the statements made and the positions or conclusions described in the following summary, and there can be no assurance the IRS or a court will not take a contrary position.

This discussion is limited to U.S. holders that hold their shares of MRC Global common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion is not a complete description of all of the U.S. federal income tax consequences of the mergers, nor does it describe (i) any tax consequences of the mergers arising under the laws of any U.S. state or local or non-U.S. jurisdiction or under any U.S. federal laws other than those pertaining to U.S. federal income taxation (such as the estate, gift, and Medicare contribution tax, for example) or (ii) the tax consequences of owning or disposing of shares of DNOW common stock received in the mergers. Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to particular U.S. holders of shares of MRC Global common stock in light of their individual circumstances (including the impact of the Medicare surtax on certain net investment income) or to U.S. holders of shares of MRC Global common stock that are subject to special treatment under the U.S. federal income tax laws, such as:

| • |  | banks, insurance companies or other financial institutions;

| • |  | “qualified foreign pension funds” as defined in Section 897(l)(2) of the Code (or any entities all of the interests of which are held by a qualified foreign pension fund);

| • |  | “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

| • |  | entities or arrangements treated as partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

| • |  | tax-exempt or governmental organizations;

| • |  | dealers in securities or traders in securities that elect to use a mark-to-market method of accounting;

| • |  | persons that hold shares of MRC Global common stock as part of a straddle, hedge, conversion transaction or other integrated investment or risk reduction transaction;

| • |  | persons that purchased or sell their shares of MRC Global common stock as part of a wash sale;

| • |  | certain former citizens or long-term residents of the United States or persons whose functional currency is other than the U.S. dollar;

| • |  | persons that are not U.S. holders;

| • |  | persons who acquired or hold their shares of MRC Global common stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

| • |  | persons subject to the alternative minimum tax;

| • |  | regulated investment companies or real estate investment trusts; and

| • |  | persons who actually or constructively hold (or actually or constructively held at any time during the five-year period ending on the date of the mergers) five percent or more (by vote or value) of any class of stock of MRC Global or DNOW.

##### Table of Contents

THE TAX CONSEQUENCES OF THE MERGERS TO A HOLDER OF MRC GLOBAL COMMON STOCK ARE COMPLEX AND WILL DEPEND ON SUCH HOLDER’S SPECIFIC SITUATION AND FACTORS NOT WITHIN DNOW’S OR MRC GLOBAL’S CONTROL. ALL MRC GLOBAL STOCKHOLDERS ARE STRONGLY ENCOURAGED TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGERS TO THEM IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE OR LOCAL, NON-U.S. OR OTHER TAX LAWS AND OF POTENTIAL CHANGES IN SUCH LAWS.

U.S. Holder Defined

For purposes of this discussion, a “U.S. holder” is a beneficial owner of MRC Global common stock that, for U.S. federal income tax purposes, is:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

| • |  | an estate the income of which is subject to U.S. federal income tax regardless of its source; or

| • |  | a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds MRC Global common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner or the partnership, upon the activities of the partnership and upon certain determinations made at the partnership or partner level. Accordingly, if you are a partner in a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that holds MRC Global common stock, you should consult your tax advisor regarding the tax consequences to you of the mergers.

U.S. Federal Income Tax Consequences of the Mergers

Assuming that the mergers are completed as currently contemplated, DNOW and MRC Global intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. The completion of the mergers is not conditioned on the mergers qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or IRS ruling to that effect. DNOW and MRC Global have not requested, and do not intend to request, any ruling from the IRS with respect to the tax consequences of the mergers. There can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. The following discussion assumes that the mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

The material U.S. federal income tax consequences of the mergers to U.S. holders of shares of MRC Global common stock will be as follows:

| • |  | a U.S. holder of shares of MRC Global common stock generally will not recognize gain or loss, except for gain or loss arising with respect to any cash received in lieu of a fractional share of DNOW common stock (as discussed in—U.S. Federal Income Tax Consequences of Cash in Lieu of Fractional Shares);

| • |  | the aggregate tax basis of the shares of DNOW common stock received by a U.S. holder of MRC Global common stock pursuant to the mergers (including any fractional share of DNOW common stock deemed received and treated as exchanged for cash, as discussed below) generally will equal the aggregate adjusted tax basis of such U.S. holder’s shares of MRC Global common stock exchanged for such DNOW common stock; and

116

##### Table of Contents

| • |  | the holding period of the DNOW common stock received by a U.S. holder in exchange for shares of MRC Global common stock pursuant to the mergers (including any fractional share of DNOW common stock deemed received and treated as exchanged for cash, as discussed below) generally will include the holding period of the MRC Global common stock exchanged for such DNOW common stock.

If a U.S. holder of shares of MRC Global common stock acquired different blocks of MRC Global common stock at different times or at different prices, such U.S. holder’s basis and holding period in its shares of DNOW common stock may be determined separately with reference to each block of MRC Global common stock. Any such U.S. holder should consult its tax advisor regarding the tax bases and holding periods of the particular shares of DNOW common stock received in the mergers.

U.S. Federal Income Tax Consequences of Cash in Lieu of Fractional Shares

A U.S. holder of shares of MRC Global common stock who receives cash in lieu of a fractional share of DNOW common stock generally will be treated as having received such fractional share pursuant to the mergers and then as having exchanged such fractional share of DNOW common stock for cash. As a result, such U.S. holder generally will recognize gain or loss equal to the difference between the amount of cash received in lieu of such fractional share and the portion of the U.S. holder’s aggregate adjusted tax basis in its MRC Global common stock surrendered that is allocated to such fractional share of DNOW common stock. Such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the mergers, the U.S. holder’s holding period for the fractional share of DNOW common stock deemed to be received is greater than one year. For U.S. holders that are non-corporate holders, long-term capital gains of individuals are generally eligible for reduced rates of taxation as compared to the rate for ordinary income or for short-term capital gains. The deductibility of capital losses is subject to limitations.

MRC GLOBAL COMMON STOCKHOLDERS ARE STRONGLY ENCOURAGED TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGERS TO THEM IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE OR LOCAL, NON-U.S. OR OTHER TAX LAWS AND OF POTENTIAL CHANGES IN SUCH LAWS.

Information Reporting and Backup Withholding

Payments of cash consideration (including any cash in lieu of a fractional share of DNOW common stock) to a holder of MRC Global common stock generally will be subject to information reporting and backup withholding (currently at a rate of 24%), unless the holder provides proof of an applicable exemption or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a holder under the backup withholding rules are not additional tax and will be allowed as a refund or credit against the holder’s U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

THE PRECEDING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS. IT IS NOT A COMPLETE ANALYSIS OR DISCUSSION OF ALL POTENTIAL TAX EFFECTS THAT MAY BE IMPORTANT TO A PARTICULAR U.S. HOLDER. ALL MRC GLOBAL STOCKHOLDERS ARE STRONGLY ENCOURAGED TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE TRANSACTIONS TO THEM, INCLUDING TAX REPORTING REQUIREMENTS AND THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE OR LOCAL, NON-U.S. OR OTHER TAX LAWS AND OF POTENTIAL CHANGES IN SUCH LAWS.

Accounting Treatment of the Mergers

DNOW and MRC Global prepare their respective financial statements in accordance with GAAP. The accounting guidance for business combinations provides for the use of the acquisition method of accounting for the mergers, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any. DNOW will be treated as the acquirer for accounting purposes. DNOW is the entity issuing the equity of the combined company. The composition of the management team and, thereby, the overall decision-making power of the combined company will be more heavily dominated by DNOW executives. Additionally, the legacy DNOW headquarters in Houston, Texas will remain the headquarters of the combined company. Each of these factors holds significant strategic implications for the combined company and, when combined with the inapplicability or relative neutrality of all other indicators considered, results in the conclusion that DNOW is the accounting acquirer.

Regulatory Approvals

Antitrust Clearance

Under the HSR Act, and the rules promulgated thereunder, the mergers cannot be completed until the parties to the merger agreement have given notification and furnished information to the FTC and the DOJ, and until the applicable waiting period has expired or has been terminated. If the DOJ or FTC issues a second request prior to the expiration of the initial 30-day waiting period, the mergers cannot close until the expiration of a second 30-day waiting period, and which would begin to run only after both parties have substantially complied with the second request, unless the second waiting period is terminated earlier.

On      , 2025, DNOW and MRC Global each filed a premerger notification and report form under the HSR Act.

At any time before or after consummation of the mergers, the FTC or the DOJ, or any state, could take such action under antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the mergers or to conditionally permit completion of the mergers subject to regulatory concessions or conditions, such as seeking the divestiture of substantial assets of DNOW or MRC Global or their respective subsidiaries. Private parties may also seek to take legal action under antitrust laws under certain circumstances.

Although neither DNOW nor MRC Global believes that the mergers will violate the antitrust laws, there can be no assurance that a challenge to the mergers on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful.

Under the terms of the merger agreement, the parties also are required to file all applicable notices, reports or other draft filings (as applicable) with respect to any non-U.S. antitrust and foreign direct investment screening processes determined to be reasonably required or advisable pursuant to the applicable antitrust and foreign direct investment laws as promptly as reasonably practical (but in no event later than 40 business days following the date of the merger agreement). The completion of the mergers is subject making these filings with, and obtaining authorizations, approvals or consents from, the relevant non-U.S. antitrust and foreign direct investment authorities or until the applicable waiting period has expired or been terminated.

U.S. Securities and Exchange Commission

In connection with the DNOW stock issuance proposal, DNOW has filed a registration statement on Form S-4, of which this joint proxy statement/prospectus forms a part, that must be declared effective by the SEC and pursuant to which the issuance of shares of DNOW common stock issuable under the merger agreement in the mergers will be registered with the SEC.

The New York Stock Exchange

The completion of the mergers is subject to approval for listing of the shares of DNOW common stock to be issued pursuant to the merger agreement on the NYSE, subject to official notice of issuance.

Exchange of Shares

For information on the exchange of MRC Global common stock for the merger consideration, please see the section entitled “The Merger Agreement — Exchange and Payment Procedures.”

Section 16 Matters

Prior to the Effective Time, the parties have agreed to take such steps as may be required to cause any dispositions of equity securities of MRC Global (including derivative securities) or acquisitions of equity securities of DNOW (including derivative securities) in connection with the merger agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to MRC Global, or will become subject to such reporting requirements with respect to DNOW, to be exempt under Rule 16b-3 under the Exchange Act.

Treatment of Indebtedness

As of March 31, 2025, DNOW had no long-term debt outstanding. As of March 31, 2025, MRC Global had approximately $371 million of total long-term debt outstanding (net of unamortized debt issuance costs and original issue discounts), consisting of $27 million of borrowings outstanding under the MRC Global credit facility and $344 million of borrowings outstanding under the MRC Global term loan. Pursuant to the merger agreement, MRC Global will deliver at or prior to the closing date (i) a payoff letter to DNOW setting forth the amount outstanding under the MRC Global credit facility and (ii) a payoff letter to DNOW setting forth the amount outstanding under the MRC Global term loan facility.

For a description of DNOW’s and MRC Global’s existing indebtedness, see DNOW’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, filed on May 7, 2025, and MRC Global’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, filed on May 7, 2025, each of which is incorporated by reference into this joint proxy statement/prospectus. Please see “Where You Can Find More Information” for additional information.

Dividend Policy

Pursuant to the merger agreement, until the Effective Time, DNOW and MRC Global will not declare, set aside or pay any dividends or other distributions except as may be provided thereunder. No dividends or other distributions declared with respect to the DNOW common stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered MRC Global common stock until the holder thereof shall surrender its MRC Global stock certificate. After the surrender of such stock certificate, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which had become payable with respect to the whole shares of DNOW common stock which the shares of MRC Global common stock represented by such stock certificate have been converted into the right to receive. Until surrendered, each such stock certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of DNOW common stock (and cash in lieu of any fractional share of DNOW common stock) as contemplated by the merger agreement and any distribution or dividend with respect to MRC Global common stock the record date for which is after the Effective Time.

Any future dividends will be at the sole discretion of the combined company board and would depend on the combined company’s financial condition, results of operations and capital requirements, as well as applicable law, regulatory constraints, industry practice and other business considerations that the combined company board considers relevant. The terms of agreements governing debt that the combined company may incur in the future may also limit or prohibit dividend payments. Accordingly, neither DNOW nor MRC Global can assure you that the combined company will pay dividends in the future.

THE MERGER AGREEMENT

The following describes the material provisions of the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference herein, and certain exhibits thereto. The summary of the material provisions of the merger agreement below and elsewhere in this joint proxy statement/prospectus is qualified in its entirety by reference to the merger agreement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. DNOW and MRC Global encourage you to read carefully the merger agreement in its entirety before making any investment or voting decisions as it is the principal legal document governing the mergers described in this joint proxy statement/prospectus. This section is only intended to provide you with information regarding the terms of the merger agreement. Neither DNOW nor MRC Global intends that the merger agreement will be a source of business or operational information about DNOW or MRC Global. Accordingly, the representations, warranties, covenants, and other agreements in the merger agreement should not be read alone, and you should read the information provided elsewhere in this joint proxy statement/prospectus and in the public filings DNOW and MRC Global make with the SEC, as described in “Where You Can Find More Information.”

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary of its terms have been included to provide you with information regarding the terms of the merger agreement. DNOW and MRC Global are responsible for considering whether additional disclosure of material information is required to make the statements in this joint proxy statement/prospectus not misleading. Factual disclosures about DNOW and MRC Global contained in this joint proxy statement/prospectus or DNOW’s or MRC Global’s public reports filed with the SEC may supplement, update or modify the factual disclosures about DNOW or MRC Global contained in the merger agreement and described in the summary. The representations, warranties and covenants made in the merger agreement by DNOW and MRC Global are qualified and subject to important limitations agreed to by DNOW and MRC Global in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were made solely for the benefit of the parties to the merger agreement and were negotiated with the principal purpose of allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties may also be subject to a contractual standard of materiality that may be different from what is generally relevant to stockholders or applicable to reports and documents filed with the SEC, and in some cases are qualified by confidential disclosures that were made by each party to the other, which disclosures are not reflected in the merger agreement or otherwise publicly disclosed. The representations and warranties in the merger agreement will not survive the completion of the mergers. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the merger agreement and subsequent developments or new information qualifying a representation or warranty may have been included or incorporated by reference into this joint proxy statement/prospectus. For the foregoing reasons, the representations, warranties and covenants or any descriptions of those provisions should not be read alone, but instead should be read together with the information provided elsewhere in this joint proxy statement/prospectus and in the documents attached to or incorporated by reference into this joint proxy statement/prospectus. Please see “Where You Can Find More Information.”

Terms of the Mergers; Merger Consideration

The merger agreement provides that, upon the terms and subject to the conditions set forth in the merger agreement, and in accordance with the applicable provisions of the DGCL and the DLLCA, as applicable, (1) Merger Sub will be merged with and into MRC Global, with MRC Global continuing as the surviving corporation in the First Merger at the Effective Time and (2) immediately following the First Merger, MRC Global will be merged with and into LLC Sub, with LLC Sub continuing as the surviving company at the effective time of the Second Merger as a wholly-owned, direct subsidiary of DNOW.

121

##### Table of Contents

At the Effective Time, by virtue of the First Merger (i) each share of MRC Global common stock held immediately prior to the Effective Time by DNOW or any of its subsidiaries, or by MRC Global or any of its subsidiaries, will be canceled and retired and will cease to exist, and no consideration will be delivered in exchange therefor; and (ii) subject to certain adjustments, each share of MRC Global common stock issued and outstanding (other than Excluded Shares) immediately prior to the Effective Time will be converted into the right to receive from DNOW 0.9489 fully paid and nonassessable shares of DNOW common stock.

At the Effective Time and by virtue of the First Merger, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time will be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the surviving corporation and will constitute the only outstanding shares of capital stock of the surviving corporation immediately following the Effective Time. From and after the Effective Time, all certificates representing the common stock of Merger Sub will be deemed for all purposes to represent the number of shares of common stock of the surviving corporation into which they were converted in accordance with the immediately preceding sentence.

At the effective time of the Second Merger and by virtue of the Second Merger, (i) each share of capital stock of MRC Global, as the surviving corporation of the First Merger, issued and outstanding immediately prior to the time the Second Merger becomes effective will be converted into and will represent one validly issued, fully paid and nonassessable (except as nonassessability may be affected by matters described in Section 18-607 of the DLLCA) unit of LLC Sub, as the surviving company of the Second Merger, and (ii) each unit of LLC Sub will be unaffected by the Second Merger and will remain outstanding as a unit of LLC Sub, as the surviving company of the Second Merger.

Completion of the Mergers

The consummation of the mergers will take place on a date to be mutually agreed upon by DNOW and MRC Global, which date will be no later than the second business day after the satisfaction or, to the extent permitted by applicable law, waiver in accordance with the terms of the merger agreement of the conditions to closing (other than any such conditions which by their nature cannot be satisfied until the closing date, which will be required to be so satisfied or (to the extent permitted by applicable law) waived in accordance with the merger agreement on the closing date), or such other time as the parties will mutually agree.

Immediately following the closing and on the closing date, MRC Global will cause the first certificate of merger to be executed and filed with the Secretary of State of the State of Delaware in accordance with the DGCL to effect the First Merger. The First Merger will become effective upon such filing and acceptance of the first certificate of merger with the Secretary of State of the State of Delaware, or at such later date and time as agreed by DNOW and MRC Global and as set forth in the first certificate of merger. Immediately following the Effective Time and on the closing date, MRC Global, as the surviving corporation of the First Merger, and LLC Sub will cause the second certificate of merger to be executed and filed with the Secretary of State of the State of Delaware in accordance with the DGCL and DLLCA to effect the Second Merger. The Second Merger will become effective one minute after the Effective Time, which MRC Global, as the surviving corporation of the First Merger, and LLC Sub will specify in the second certificate of merger.

DNOW and MRC Global have targeted to complete the mergers in the fourth quarter of 2025, subject to the receipt of the required approval of DNOW stockholders and approval of MRC Global stockholders, applicable regulatory approvals and the satisfaction or waiver of the other conditions to the mergers, in each case, as set forth in the merger agreement (described below under “— Conditions to Completion of the Mergers”).

Exchange and Payment Procedures

Prior to the closing date, DNOW and the MRC Global will mutually select a bank or trust company to act as exchange agent in the First Merger, and, prior to the Effective Time, DNOW will enter into an agreement with

122

##### Table of Contents

the exchange agent, which will provide that, at or prior to the Effective Time, DNOW will deposit with the exchange agent evidence of shares in book-entry form representing shares of DNOW common stock to pay the aggregate merger consideration. DNOW will also make available to the exchange agent, from time to time as needed, cash sufficient to pay any dividends or other distributions declared or made with respect to shares of DNOW common stock with a record date after the Effective Time and to make cash payments in lieu of issuing fractional shares upon the conversion of MRC Global common stock into the merger consideration.

No interest will be paid or accrue on any cash portion of the merger consideration payable upon surrender of any MRC Global common stock certificate (or affidavits of loss in lieu thereof) or MRC Global book-entry shares.

DNOW, MRC Global, LLC Sub and the exchange agent will be entitled to deduct and withhold from the consideration payable or otherwise deliverable pursuant to the merger agreement such amounts as may be required to be deducted or withheld under applicable law.

If any portion of the merger consideration deposited with the exchange agent remains undistributed as of six months after the Effective Time, such merger consideration will be delivered to DNOW upon demand, and any former MRC Global stockholder who has not surrendered its MRC Global common stock certificates to the exchange agent and any holder of MRC Global book-entry shares who has not cashed any check payable to them in accordance with the merger agreement will thereafter look only to DNOW for satisfaction of their claims for DNOW common stock, cash in lieu of any fractional shares of DNOW common stock or any dividends or distributions to be paid pursuant to the merger agreement, subject to applicable abandoned property law, escheat laws or similar laws.

Certificates

As soon as practicable after the Effective Time, but in no event more than three business days after the closing date, DNOW will cause the exchange agent to mail to the record holders of MRC Global common stock certificates: (i) a letter of transmittal; and (ii) instructions for use in effecting the surrender of MRC Global common stock certificates in exchange for DNOW common stock, and any cash in lieu of a fractional share, as well as any dividends or distributions to be paid. Upon surrender of an MRC Global common stock certificate to the exchange agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the exchange agent or DNOW, (A) the holder of such MRC Global common stock certificate will be entitled to receive in book-entry form the number of whole shares of DNOW common stock that such holder has the right to receive pursuant to the merger agreement (and cash in lieu of any fractional share of DNOW common stock), as well as any dividends or distributions to be paid pursuant to the merger agreement, and (B) the MRC Global common stock certificate so surrendered will be immediately canceled.

If any MRC Global common stock certificate will have been lost, stolen or destroyed, DNOW may, in its discretion and as a condition precedent to the issuance of any shares of DNOW common stock, require the owner of such lost, stolen or destroyed MRC Global common stock certificate to provide an appropriate affidavit and to deliver a bond (in such sum as DNOW may reasonably direct) as indemnity against any claim that may be made against the exchange agent, DNOW or LLC Sub with respect to such MRC Global common stock certificate. Upon the making of such affidavit, the exchange agent will issue in exchange for such lost, stolen or destroyed MRC Global common stock certificate the merger consideration payable in respect of the shares of MRC Global common stock formerly represented by such certificate.

Non-DTC Book-Entry Shares

Promptly after the Effective Time, DNOW will cause the exchange agent to (i) issue, as of the Effective Time, to each holder of MRC Global book-entry securities not held through DTC (other than Excluded Shares) that number of book-entry whole shares of DNOW common stock that the holder is entitled to receive pursuant to

123

##### Table of Contents

the merger agreement and cancel such book-entry shares of MRC Global common stock, (ii) mail to each holder of MRC Global book-entry securities not held through DTC (other than Excluded Shares) a check in the amount of any cash payable in respect of any fractional share interest of the holder’s MRC Global book-entry securities and any post-Effective Time distributions pursuant to the merger agreement and (iii) deliver to each holder of MRC Global book-entry securities not held through DTC (other than Excluded Shares) a statement reflecting the number of shares of DNOW common stock issued to such holder pursuant to the merger agreement.

DTC Book-Entry Shares

With respect to MRC Global book-entry securities held through DTC, DNOW and MRC Global will cooperate to establish procedures with the exchange agent and DTC to ensure that the exchange agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the closing date, upon surrender of shares of MRC Global common stock held of record by DTC or its nominees in accordance with DTC’s customary surrender procedures, the merger consideration and any dividends or distributions that DTC has the right to receive pursuant to the merger agreement, and cancel such MRC Global book-entry securities.

DNOW Management and DNOW Board Following the Mergers

Pursuant to the terms of the merger agreement, DNOW is required to take all necessary actions so that upon and after the Effective Time, the DNOW board is comprised of ten directors, including two directors selected from MRC Global’s board of directors by DNOW prior to closing. On July 17, 2025, DNOW notified MRC Global that DNOW had selected George J. Damiris and Ronald L. Jadin to be appointed to the DNOW board effective immediately upon closing.

There will be no change to the management of DNOW as a result of the mergers, and the officers of DNOW as of immediately prior to the Effective Time will continue to serve as the officers of DNOW after completion of the mergers.

Employee Matters

Pursuant to the merger agreement, DNOW has agreed that for a period of one year following the Effective Time, DNOW will provide each employee of DNOW or its subsidiaries who was an employee of MRC Global or any of its subsidiaries immediately prior to the Effective Time and who continues to remain employed with DNOW or any of its subsidiaries immediately following the Effective Time (each, a “continuing employee”) with: (i) base wage rate or base salary, as applicable, that are no less favorable than were provided to the continuing employee immediately prior to the Effective Time, (ii) short-term cash incentive opportunities (excluding any retention, change in control, transaction or similar compensation, and any equity-based compensation opportunities) that are (A) substantially comparable, in the aggregate, to those to which such continuing employee was entitled immediately prior to the Effective Time or (B) substantially comparable, in the aggregate, to those provided to similarly-situated employees employed by DNOW or any DNOW subsidiary, (iii) severance benefits that are (A) substantially comparable to those to which such continuing employee was entitled immediately prior to the Effective Time or (B) substantially comparable to those provided to similarly-situated employees employed by DNOW or any DNOW subsidiary, and (iv) health, welfare, and fringe benefits (excluding any equity-based, long-term incentive, retention, change in control or similar one-time or special benefits or arrangements, any defined benefit pension, non-qualified deferred compensation, and post-termination or retiree health or welfare benefits) that are that are substantially comparable in the aggregate to (a) those that

133

##### Table of Contents

were provided to the continuing employee immediately prior to the Effective Time under MRC Global’s benefit plans previously disclosed to DNOW or (b) those provided to similarly situated employees of DNOW or any DNOW subsidiary, in each case, excluding the excluded benefits listed in this clause (iv).

Subject to applicable law, for purposes of vesting, eligibility to participate and, solely for vacation and paid time off policies, determining levels of benefits (but not, for the avoidance of doubt, for purposes of benefit accrual under any defined benefit pension plan) under the DNOW benefit plans in which MRC Global employees participate after the Effective Time (the “New Plans”), each MRC Global employee will be credited with his or her years of service with MRC Global and its subsidiaries before the Effective Time, to the same extent and for the same purpose as such MRC Global employee was entitled, before the Effective Time, to credit for such service under the corresponding MRC Global benefit plan in which such MRC Global employee participated immediately prior to the Effective Time.

In addition, for the plan year in which the Effective Time occurs (or if later, during the plan year in which such participation first commences), DNOW will use commercially reasonable efforts to cause: (i) for purposes of each New Plan providing medical, dental, pharmaceutical or vision benefits to any MRC Global employee, all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such MRC Global employee and his or her covered dependents to the same extent waived or satisfied under the corresponding MRC Global benefit plan in which such MRC Global employee participated immediately prior to the Effective Time and (ii) eligible expenses paid by each MRC Global employee and his or her covered dependents during the plan year that includes the Effective Time under the MRC Global benefit plans that are group health plans to be taken into account for purposes of satisfying the corresponding deductible, coinsurance and maximum out-of-pocket requirements applicable to such MRC Global employee and his or her covered dependents under the corresponding New Plan that is a group health plan.

At the written request of DNOW provided no later than five days prior to the closing date, MRC Global or its applicable subsidiary will, at least one day prior to the closing date, adopt written resolutions to terminate any MRC Global benefit plan that is intended to be qualified under Section 401(a) of the Code (the “MRC Global 401(k) Plan”) and to fully vest all participants under the MRC Global 401(k) Plan, such termination and vesting to be effective no later than the day preceding the closing date. To the extent the MRC Global 401(k) Plan is terminated pursuant to the foregoing, as soon as administratively practicable following the closing date, DNOW will provide that each MRC Global employee that participates in the MRC Global 401(k) Plan immediately prior to the closing date will be eligible to participate in a DNOW benefit plan that is intended to qualified under Section 401(a) of the Code of DNOW or one of its affiliates (the “DNOW 401(k) Plan”) and such DNOW 401(k) Plan will accept “eligible rollover distributions” (as such term is defined under Section 402(c)(4) of the Code) in the form of cash, promissory note (in the case of loans) to the extent allowable under the terms of the DNOW 401(k) Plan or any combination thereof, from the MRC Global 401(k) Plan to the extent elected by an MRC Global employee.

Nothing contained in the merger agreement will (i) create or confer any rights, remedies or claims upon any employee, director, officer or individual service provider or any right of employment or engagement or continued employment or engagement or any particular term or condition of employment or engagement for any MRC Global employee or any other person, (ii) be considered or deemed to establish, amend or modify any DNOW benefit plan, MRC Global benefit plan, New Plan or any other benefit or compensation plan, program, policy, agreement, arrangement or contract, (iii) limit the ability of DNOW, any subsidiary of DNOW or the surviving company or any of their respective affiliates to amend, modify or terminate any DNOW benefit plan, MRC Global benefit plan, New Plan or any other benefit or compensation plan, program, policy, agreement or arrangement or (iv) confer any rights or benefits (including any third-party beneficiary rights) on any person other than the parties to the merger agreement. The merger agreement will not be construed to prevent the termination of employment of any MRC Global employee.

Such DNOW RSU will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are set forth in the corresponding award agreement (except that such award will be payable in DNOW common stock).

The merger agreement also provides that, at the Effective Time, each MRC Global PSU that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will, by virtue of the occurrence of the closing and without any action by DNOW, Merger Sub, LLC Sub, MRC Global or the holder thereof, be canceled, and the holder thereof will then become entitled to receive, in full satisfaction of the rights of such holder with respect thereto, the number of shares of MRC Global common stock (rounded to the nearest share) subject to the MRC Global PSU, which shares of MRC Global common stock will be converted into the right to receive (A) the merger consideration with respect to each share of MRC Global common stock subject to such MRC Global PSU that vest based on the determination of performance set forth in the applicable award agreement, reduced by the number of shares of DNOW common stock required or permitted to be deducted to satisfy applicable withholding and similar taxes and (B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such MRC Global PSU, if any, less applicable withholding and similar taxes, in each case, payable or deliverable by the surviving corporation as soon as reasonably practicable, but no later than, five business days following the Effective Time.

The merger agreement also provides that, at the Effective Time, each outstanding MRC Global PSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will be canceled and converted into a DNOW RSU in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the number of shares of MRC Global common stock subject to such MRC Global PSU immediately prior to the Effective Time that vest based on the determination of performance set forth in the applicable award agreement multiplied by (2) the exchange ratio. Such DNOW RSU will vest and be payable on the same terms and conditions (including “double-trigger” vesting provisions) as are

135

##### Table of Contents

set forth in the corresponding award agreement (except that such award will be payable in DNOW common stock and such award will no longer be subject to performance metrics). For purposes of the immediately preceding sentence, the number of shares of MRC Global common stock subject to such MRC Global PSU will be deemed to be the number of shares subject to the MRC Global PSU with performance deemed achieved, except as previously disclosed to DNOW, in accordance with the terms and conditions of the applicable award agreement governing such MRC Global PSU immediately prior to the Effective Time.

To the extent that any award described herein constitutes nonqualified deferred compensation subject to Section 409A of the Code, any payment contemplated hereby with respect to such award will be made in accordance with the merger agreement and the applicable award’s terms or, if later, at the earliest time permitted under the terms of such award that will not result in the application of a tax or penalty under Section 409A of the Code.

Without limiting the foregoing, each party will use reasonable best efforts to avoid or eliminate each and every impediment under antitrust laws and foreign investment laws so as to enable the closing to occur as soon as reasonably possible (and in any event no later than the outside date), including (i) using reasonable best efforts to avoid the entry of, or to have vacated or terminated as promptly as practicable and in any event before the outside date, any order that would restrain, prevent or delay the closing, including without limitation defending through litigation on the merits (including appeal) any relevant claim asserted in any court by any person and (ii) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise: (A) the sale, divestiture or disposition of businesses, product lines or assets of DNOW, MRC Global and their respective subsidiaries, (B) any conditions relating to, or changes or restrictions in, the operations of any such businesses, product lines or assets, (C) any modification of the terms of sale with any customer, vendor or other third party and (D) otherwise taking or committing to take actions that after the closing date would limit DNOW or any of its subsidiary’s freedom of action with respect to, or its or their ability to retain any such businesses, product lines or assets. Notwithstanding anything to the contrary in the merger agreement, neither party will be required to effect or agree to any regulatory remedy as outlined in clauses (A) through (D) that individually or in the aggregate with any other regulatory remedy, would reasonably be expected to have a material adverse effect on the business, operations, financial condition or results of operations of DNOW and its subsidiaries, taken as a whole, after giving effect to the mergers, which shall be deemed a consolidated group of entities of the size and scale of a hypothetical company that is 100% of the size of (xx) DNOW and its subsidiaries and (yy) MRC Global and its subsidiaries, taken as a whole, as of the date of the merger agreement.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

The accompanying unaudited pro forma combined financial data (the “Pro Forma Financial Statements”) are provided to aid DNOW Inc. (“DNOW”) and MRC Global Inc. (“MRC Global”) stockholders in their analysis of the financial aspects of the mergers. The Pro Forma Financial Statements combine the historical consolidated financial position and results of operations of MRC Global after giving effect to the mergers as further described in Note 1 — Description of the Mergers and the pro forma effects of certain assumptions and adjustments described in “Notes to the Unaudited Pro Forma Combined Financial Statements” below. The Pro Forma Financial Statements have been prepared to give effect to the following:

| • |  | Application of the acquisition method of accounting under the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”) where the assets acquired and liabilities assumed of MRC Global will be recorded by DNOW at their respective fair values as of the closing date;

| • |  | Preliminary adjustments to conform the financial statement presentation of MRC Global to those of DNOW; and

| • |  | Adjustments to reflect estimated post-combination impacts, including transaction costs of the mergers (as defined below in Note 1 — Description of the Mergers below).

The Pro Forma Financial Statements of DNOW also give effect to acquisitions that have already occurred and are considered material transactions separate from the mergers:

| • |  | For the year ended December 31, 2024, DNOW completed the acquisitions of Whitco Supply, LLC and Trojan Rentals, LLC (collectively, the “Other Acquisitions”). DNOW has included the financial results of the Other Acquisitions in its consolidated financial statements from the date of the Other Acquisitions. The unaudited combined pro forma data has been presented as if the Other Acquisitions occurred on January 1, 2024. This information is based on historical results of operations, adjusted to give effect to pro forma events that are directly attributable to the Other Acquisitions and factually supportable. The pro forma data is for informational purposes only and is not indicative of the results of operations that would have been achieved had the Other Acquisitions occurred at the beginning of fiscal year 2024.

The following Pro Forma Financial Statements and related notes are based on and should be read in conjunction with:

| • |  | The historical audited consolidated financial statements of DNOW and the related notes included in DNOW’s Annual Report on Form 10-K as of and for the year ended December 31, 2024;

| • |  | The historical audited consolidated financial statements of MRC Global and the related notes included in MRC Global’s Annual Report on Form 10-K as of and for the year ended December 31, 2024;

| • |  | The historical unaudited interim consolidated financial statements of DNOW and the related notes included in DNOW’s Quarterly Report on Form 10-Q as of and for the three months ended March 31, 2025; and

| • |  | The historical unaudited interim consolidated financial statements of MRC Global and the related notes included in MRC Global’s Quarterly Report on Form 10-Q as of and for the three months ended March 31, 2025.

The unaudited pro forma combined balance sheet as of March 31, 2025, gives pro forma effect to the mergers as if they had occurred on March 31, 2025. The unaudited pro forma combined statements of operations for the three months ended March 31, 2025, and for the year ended December 31, 2024, give pro forma effect to the mergers as if they had occurred on January 1, 2024.

The Pro Forma Financial Statements are provided for informational purposes only. The Pro Forma Financial Statements are not necessarily, and should not be assumed to be, an indication of the actual results that would have been achieved had the mergers been completed as of the dates indicated or that may be achieved in the future. The Pro Forma Financial Statements have been prepared in accordance with Article 11 of Regulation S-X promulgated by the SEC, as amended by the final rule, Release No. 33-10786 Amendments to Financial Disclosures about Acquired and Disposed Businesses, using the assumptions set forth in the notes to the Pro Forma Financial Statements. Further, there may be additional charges related to any potential restructuring or other integration activities resulting from the mergers, the timing, nature and amount of which management cannot identify or calculate as of the date of this joint proxy statement/prospectus, and thus, these charges are not reflected in the Pro Forma Financial Statements.

In accordance with the Merger Agreement, DNOW and MRC Global will effect a transaction to combine their respective businesses through: (a) the merger of Merger Sub with and into MRC Global (the “First Merger”), with MRC Global continuing as the surviving corporation in the First Merger (the time the First Merger becomes effective, the “Effective Time”), and (b) the merger of MRC Global with and into LLC Sub (the “Second Merger” and together with the First Merger, the “mergers”), with LLC Sub continuing as the surviving company as a wholly-owned, direct subsidiary of DNOW.

The Merger Agreement provides that each issued and outstanding share of common stock of MRC Global, par value of $0.01 per share (the “MRC Global common stock”), will be converted into the right to receive 0.9489 shares of common stock of DNOW, par value of $0.01 per share (the “DNOW common stock”) with cash paid in lieu of the issuance of fractional shares, if any (the “merger consideration”).

The Merger Agreement also provides that each share of restricted MRC Global common stock issued under MRC Global’s Amended and Restated Omnibus Incentive Plan (the “MRC Global equity plan”) that vests solely on the basis of time (each a “MRC Global RSA”) that is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest in full immediately prior to the Effective Time and (ii) be cancelled and converted into the right to receive (A) the merger consideration with respect to each MRC Global RSA, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the Merger Agreement and (B) an amount in cash equal to the accrued but unpaid dividends with respect to each MRC Global RSA.

The Merger Agreement also provides that each restricted stock unit granted pursuant to the MRC Global equity plan that vests solely on the basis of time (each a “MRC Global RSU”) that was granted prior to February 2024 and is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest in full immediately prior to the Effective Time (including with respect to any dividend equivalents credited with respect to such MRC Global RSU that remain unpaid as of the Effective Time) and (ii) be cancelled and converted into the right to receive the merger consideration with respect to each share of MRC Global common stock subject to such MRC Global RSU, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the Merger Agreement.

The Merger Agreement also provides that each MRC Global RSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, be cancelled and converted into an award of restricted stock units representing the right to receive DNOW common stock (each a “DNOW RSU”) in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the total number of shares of MRC Global common stock subject to such award of MRC Global RSUs immediately prior to the Effective Time multiplied by (2) 0.9489. Such DNOW RSUs will vest on the same terms and conditions (including “double-trigger” vesting provisions) applicable to the corresponding MRC Global RSU immediately prior to the Effective Time.

The Merger Agreement also provides that, to the extent provided for in the applicable award agreement, each outstanding restricted stock unit granted pursuant to the MRC Global equity plan that is subject to performance-based vesting (each a “MRC Global PSU”) that was granted prior to February 2024 and that is

outstanding immediately prior to the Effective Time will automatically, by virtue of the occurrence of the closing of the mergers, (i) vest immediately prior to the Effective Time with respect to a number of shares of MRC Global common stock that vest based on the determination of performance set forth in the applicable award agreement (including with respect to any dividend equivalents credited with respect to such MRC Global PSU that remain unpaid as of the time of the First Merger) and (ii) be cancelled and converted into the right to receive, without interest, the merger consideration with respect to each share of MRC Global common stock that vests pursuant to such MRC Global PSU, with cash paid in lieu of fractional shares of DNOW common stock in accordance with the Merger Agreement.

The Merger Agreement also provides that, to the extent provided for in the applicable award agreement, each outstanding MRC Global PSU that was granted in February 2024 or later and is outstanding immediately prior to the Effective Time shall be cancelled and converted into a DNOW RSU award in respect of that number of shares of DNOW common stock (rounded to the nearest whole share) equal to the product of (1) the number of shares of MRC Global common stock that vest based on the determination of performance set forth in the applicable award agreement multiplied by (2) 0.9489. Such DNOW RSUs will vest on the same terms and conditions (including “double-trigger” vesting provisions) applicable to the corresponding MRC Global PSU immediately prior to the time of the First Merger (except that such DNOW RSUs will no longer be subject to performance metrics).

Note 2. Basis of Pro Forma Presentation

Basis of Presentation

The unaudited pro forma combined balance sheet as of March 31, 2025, combines the historical consolidated balance sheets of DNOW and MRC Global, giving effect to the mergers as if they had occurred on March 31, 2025. The unaudited pro forma combined statements of operations for the three months ended March 31, 2025, and for the year ended December 31, 2024, combines the historical consolidated statements of operations of DNOW and MRC Global, giving effect to the mergers as if they had occurred on January 1, 2024.

The Pro Forma Financial Statements and explanatory notes have been prepared using the acquisition method of accounting with DNOW as the accounting acquirer of MRC Global. Under the acquisition method of accounting, the assets and liabilities of MRC Global, as of closing, will be recorded by DNOW at their estimated fair values and any excess of the merger consideration over the fair value of MRC Global’s net assets will be allocated to goodwill, if applicable. The pro forma allocation of the merger consideration reflected in the Pro Forma Financial Statements is subject to adjustment and may vary materially from the actual allocation that will be recorded as of the close date.

The Pro Forma Financial Statements have been presented for illustrative purposes only and are not necessarily indicative of the financial condition or results of operations that would have been realized had the mergers occurred as of the dates indicated, nor are they meant to be indicative of any anticipated future financial condition or results of operations of DNOW and its consolidated subsidiaries after giving effect to the mergers (the “combined company”), nor does it reflect adjustments for any anticipated synergies, operating efficiencies, tax savings or cost savings. Actual financial condition and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

The unaudited pro forma adjustments represent management’s estimates based on currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances and are subject to change as additional information becomes available and analyses are performed. Assumptions and estimates underlying the unaudited pro forma adjustments set forth in the unaudited Pro Forma Financial Statements are described in the accompanying notes.

Discontinued Operations Adjustments

On December 13, 2024, MRC Global entered into a definitive agreement to sell assets associated with its Canada operations (“MRC Global Canada”) to EMCO Corporation, and on March 14, 2025, MRC Global completed the sale.

MRC Global presented the operations of MRC Global Canada as discontinued operations for the year ended December 31, 2024 and three months ended March 31, 2025. Therefore, the Pro Forma Financial Statements exclude the results of operations of MRC Global Canada because those businesses will not be considered part of the acquiring entity’s continuing operations.

Note 3. Preliminary Purchase Price Allocation

Management performed a preliminary estimation of fair values of the MRC Global assets acquired and liabilities assumed as of March 31, 2025. The preliminary purchase accounting was based on a benchmarking analysis of similar transactions in the industry to identify value allocations of acquisition consideration to assets acquired and liabilities assumed. As such, the preliminary fair value estimates are subject to change based on the final valuations, and these changes could be material.

The estimated preliminary fair values of the MRC Global assets and liabilities are based on discussions with MRC Global’s management, preliminary valuation studies, the transaction due diligence and information presented in MRC Global’s public filings. The final purchase price and purchase price allocation may be different than the information that is presented herein, and these differences could be material.

Preliminary Estimated Purchase Price

The total preliminary merger consideration is calculated as follows (in millions, except exchange ratio, shares, and per share price):

MRC Global common stock as of March 31, 2025 |  |  | 86,095,852 |
MRC Global RSUs and MRC Global PSUs to be vested in connection with the mergers |  |  | 718,973 |
Exchange ratio |  |  | 0.9489 |
Shares of DNOW common stock issued at closing |  |  | 82,378,587 |
Price per share of DNOW common stock(1) |  | $ | 14.60 |
Equity consideration for the conversion of MRC Global common stock outstanding |  | $ | 1,202 |
Fair value of replacement MRC Global RSUs, MRC Global RSA, and MRC Global PSU awards attributable to the purchase price |  | $ | 9 |
Estimated repayment of certain existing indebtedness of MRC Global |  | $ | 376 |
Preliminary merger consideration |  | $ | 1,587 |

(1) | The final purchase price will be based on the fair value of the issued and outstanding shares of DNOW common stock at the closing. For purposes of preparing these Pro Forma Financial Statements, the estimated fair value is based on the closing price of the shares of DNOW common stock on June 25, 2025.

A sensitivity analysis related to the fluctuation in the price of DNOW common stock was performed to assess the impact of a hypothetical change of 10% on the per share closing price of DNOW common stock on the merger consideration transferred at closing. DNOW believes that a 10% fluctuation in the market price of the DNOW common stock is reasonably possible based on historical volatility. An increase or decrease in the closing price of DNOW common stock could potentially result in a change of goodwill as of the closing date.

Decrease of 10% |  | $ | 13.14 |  |  | $ | 1,467 |

Preliminary Estimated Purchase Price Allocation

Cash |  | $ | 63 |
Accounts receivable, net |  |  | 442 |
Inventories, net |  |  | 460 |
Other current assets |  |  | 30 |

Total consideration effectively transferred |  | $ | 1,587 |

All adjustments from the application of the purchase price allocation are within the adjustments described in Note 5 below.

Note 4. Significant Accounting Policies and Reclassification Adjustments

During the preparation of the Pro Forma Financial Statements, DNOW performed a preliminary analysis of MRC Global’s historical financial data to identify differences in accounting policies and financial statement presentation as compared to those of DNOW. Management is currently evaluating for significant accounting policy differences between the two entities. Upon consummation of the mergers, DNOW management will perform a comprehensive review of the accounting policies and may identify differences in accounting policies between the two entities which, when conformed, could be material.

Certain reclassifications are reflected in the unaudited pro forma combined balance sheet and unaudited pro forma combined statement of operations to conform presentation between DNOW and MRC Global. These reclassifications have no effect on previously reported total assets, total liabilities and stockholders’ equity, or net income of DNOW or MRC Global. The Pro Forma Financial Statements may not reflect all reclassifications

Note 6. Adjustments to the Unaudited Pro Forma Combined Statements of Operations

Merger adjustments include the following adjustments related to the unaudited pro forma combined statements of operations for the three months ended March 31, 2025, and for the year ended December 31, 2024, as follows:

| (a) | Represents a net adjustment of ($3) million and ($12) million for the three months ended March 31, 2025, and the year ended December 31, 2024, respectively, to (1) reflect the removal of historical depreciation expense related to warehousing, selling and administrative and (2) recognize depreciation related to tangible assets.

| (c) | Represents the recognition of new stock-based compensation expense for the post-combination portion of the cancelled and exchanged MRC Global equity awards.

As the 2022 and 2023 MRC Global RSUs and MRC Global PSUs, if any, will be settled at closing with no future service required, the value of these awards will be recognized as part of merger consideration.

It is being assumed that certain of the awards of the 2024 and 2025 MRC Global RSUs, MRC Global RSAs, and MRC Global PSUs have a contractual provision that will cause the accelerated vesting of those awards resulting in the entire post-combination portion of these awards being recognized as compensation expense immediately after the closing of the mergers.

The remaining 2024 and 2025 MRC Global RSU awards, MRC Global RSA awards and MRC Global PSU awards are considered cancelled and exchanged for DNOW RSUs with the incremental value of the awards being recorded post-combination due to services to be performed after the closing of the mergers.

ANTI-TAKEOVER PROVISIONS

DNOW is governed by Section 203 of the DGCL, which prohibits a defined set of transactions between a Delaware corporation and an “interested stockholder.” An interested stockholder is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision may prohibit business combinations between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder. The term “business combination” is broadly defined to include a broad array of transactions, including mergers, consolidations, sales or other dispositions of assets having a total value in excess of 10% of the consolidated assets of the corporation or all of the outstanding stock of the corporation, and some other transactions that would increase the interested stockholder’s proportionate share ownership in the corporation. This prohibition is effective unless: (i) the business combination or the transaction that resulted in the stockholder becoming an interested stockholder is approved by such corporation’s board prior to the time the interested stockholder becomes an interested stockholder; (ii) the interested stockholder acquired at least 85% of the voting stock of the corporation, other than stock held by directors who are also officers or by qualified employee stock plans, in the transaction in which it becomes an interested stockholder; or (iii) the business combination is approved by a majority of the board of the corporation and by the affirmative vote of 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

HOUSEHOLDING OF PROXY MATERIALS

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more stockholders sharing the same address by delivering a single proxy statement or a single notice addressed to those stockholders. This process, commonly called “householding,” provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement or notice to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement or notice, or if your household is receiving multiple copies of these documents and you wish to request that future deliveries be limited to a single copy, please notify your broker.

Section 1.2 Effect of the Mergers. The Mergers shall have the effects set forth in this Agreement and in the provisions of the DGCL and the DLLCA, as applicable, including that (a) at the Effective Time, all of the properties, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation and (b) at the Second Effective Time, all of the properties, rights, privileges, immunities, powers and franchises of the Surviving Corporation and LLC Sub shall vest in the Surviving Company, and all debts, liabilities and duties of the Surviving Corporation and LLC Sub shall become the debts, liabilities and duties of the Surviving Company.

Section 1.4 Organizational Documents.

(a) At the Effective Time, the certificate of incorporation and bylaws of the Company shall be amended and restated in their entirety to be in substantially the form of the certificate of incorporation and bylaws of Merger Sub in effect immediately prior to the Effective Time. The certificate of incorporation and bylaws of Merger Sub, as amended and restated pursuant to the immediately preceding sentence, shall be the certificate of incorporation and bylaws of the Surviving Corporation until thereafter duly amended as provided therein or by applicable Law.

(b) At the Second Effective Time, the certificate of formation and limited liability company agreement of LLC Sub in effect immediately prior to the Second Effective Time shall be the certificate of formation and limited liability company agreement of the Surviving Company, until duly amended as provided therein or by applicable Law.

Section 1.5 Directors and Officers.

(a) Subject to applicable Law, the parties shall take all actions necessary such that the persons who are the directors and officers of Merger Sub immediately prior to the Effective Time shall be the initial directors and officers of the Surviving Corporation, and such initial directors and officers shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

(b) Subject to applicable Law, the parties shall take all action necessary such that the officers of LLC Sub immediately prior to the Second Effective Time shall continue to be the officers of the Surviving Company, and such officers shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

Section 1.6 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the First Merger and without any further action on the part of Parent, Merger Sub, the Company or any holder of capital stock thereof:

(i) each share of common stock, $0.01 par value, of the Company (the “Company Common Stock”) held immediately prior to the Effective Time by Parent or any of Parent’s Subsidiaries (the “Parent Subsidiaries”), or by the Company or any of the Company’s Subsidiaries (the “Company Subsidiaries”) (collectively, the “Excluded Shares”), shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; and

(ii) subject to Section 1.6(b) and Section 1.6(c), each share of Company Common Stock issued and outstanding (other than Excluded Shares) immediately prior to the Effective Time shall be converted into the right to receive from Parent 0.9489 fully paid and nonassessable shares of common stock, $0.01 par value, of Parent (the “Parent Common Stock”).

The number of shares of Parent Common Stock into which each share of Company Common Stock shall be converted, as specified in Section 1.6(a)(ii) (as such number may be adjusted in accordance with Section 1.6(b)), is referred to as the “Exchange Ratio.” The aggregate number of shares of Parent Common Stock issuable pursuant to Section 1.6(a)(ii), together with any cash to be paid in lieu of any fractional shares of Parent Common Stock in accordance with Section 1.8(f), is referred to as the “Merger Consideration.”

(b) Without limiting the parties’ respective obligations under Section 4.1 and Section 4.2, including Section 4.1(b)(i) and Section 4.2(b)(i), if, during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Common Stock or Parent Common Stock shall occur as a result of any reclassification, recapitalization, stock split (including reverse stock split), merger, combination, exchange or readjustment of shares, subdivision or other similar transaction, or any stock dividend thereon with a record date during such period, then the Exchange Ratio and any other amounts payable pursuant to this Agreement shall be appropriately adjusted to eliminate the effect of such event on the Exchange Ratio or any such other amounts payable pursuant to this Agreement to provide to the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action.

##### Table of Contents

(c) At the Effective Time, by virtue of the First Merger and without any action on the part of Parent, Merger Sub, the Company or any holder of capital stock thereof, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one (1) validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation immediately following the Effective Time. From and after the Effective Time, all certificates representing the common stock of Merger Sub shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

(d) At the Second Effective Time, by virtue of the Second Merger and without any action on the part of Parent, the Surviving Corporation, LLC Sub or any holder of capital stock thereof, (i) each share of capital stock of the Surviving Corporation issued and outstanding immediately prior to the Second Effective Time shall be converted into and shall represent one (1) validly issued, fully paid and nonassessable (except as nonassessability may be affected by matters described in Section 18-607 of the DLLCA) unit of the Surviving Company and (ii) each unit of LLC Sub shall be unaffected by the Second Merger and shall remain outstanding as an unit of the Surviving Company.

Section 1.7 Closing of the Company’s Transfer Books. At the Effective Time:

(a) all shares of Company Common Stock outstanding immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and

(i) each certificate formerly representing any share of Company Common Stock (other than an Excluded Share) (a “Company Stock Certificate”) and

(ii) each Book-Entry Common Share formerly representing any share of Company Common Stock (other than an Excluded Share) shall represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by Section 1.6 and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 1.8(c), and all holders of Company Stock Certificates or Book-Entry Common Shares shall cease to have any rights as stockholders of the Company; and

(b) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid Company Stock Certificate is presented to the Exchange Agent or to the Surviving Company or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in this Article I.

Section 1.8 Exchange Fund; Exchange of Certificates.

(a) Prior to the Closing Date, Parent and the Company shall mutually select a bank or trust company, which may be the transfer agent for the Parent Common Stock, to act as exchange agent in the First Merger (the “Exchange Agent”), and, prior to the Effective Time, Parent shall enter into an agreement with the Exchange Agent, which will provide that, at or prior to the Effective Time, Parent shall deposit with the Exchange Agent evidence of shares in book-entry form representing shares of Parent Common Stock to pay the aggregate Merger Consideration pursuant to Section 1.6(a)(ii) and Section 1.8(f). The shares of Parent Common Stock so deposited with the Exchange Agent, together with (x) any dividends or distributions received by the Exchange Agent with respect to such shares and (y) cash as payment for fractional shares pursuant to Section 1.8(f), are referred to collectively as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued in exchange for Company Common Stock pursuant to this Agreement out of the Exchange Fund. Except as contemplated by this Section 1.8 and Section 1.9, the Exchange Fund shall not be used for any other purpose. To the extent, for any reason, the amount in the Exchange Fund is

A-4

##### Table of Contents

below that amount required to make prompt payment of the aggregate cash payments contemplated by this Section 1.8 and Section 1.9, Parent shall promptly replace, restore or supplement the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to make the payment of the aggregate cash payments contemplated by this Section 1.8 and Section 1.9.

(b) As soon as practicable after the Effective Time, but in no event more than three (3) Business Days after the Closing Date, Parent shall cause the Exchange Agent to mail to the record holders of Company Stock Certificates:

(i) a letter of transmittal in customary form agreed to by Parent and the Company prior to Closing and containing a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent; and

(ii) instructions for use in effecting the surrender of Company Stock Certificates in exchange for Parent Common Stock, as provided in Section 1.6, and any cash in lieu of a fractional share which the shares of Company Common Stock represented by such Company Stock Certificates shall have been converted into the right to receive pursuant to this Agreement, as well as any dividends or distributions to be paid pursuant to Section 1.8(c).

Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, (A) the holder of such Company Stock Certificate shall be entitled to receive in book-entry form the number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.6 (and cash in lieu of any fractional share of Parent Common Stock), as well as any dividends or distributions to be paid pursuant to Section 1.8(c), and (B) the Company Stock Certificate so surrendered shall be immediately canceled.

(c) No dividends or other distributions declared with respect to the Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate until the holder thereof shall surrender such Company Stock Certificate in accordance with this Article I. After the surrender of a Company Stock Certificate in accordance with this Article I, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which had become payable with respect to the whole shares of Parent Common Stock which the shares of Company Common Stock represented by such Company Stock Certificate have been converted into the right to receive.

(d) Until surrendered as contemplated by this Section 1.8, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by this Article I and any distribution or dividend with respect to Parent Common Stock the record date for which is after the Effective Time.

(e) In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, shares in book-entry form representing the proper number of shares of Parent Common Stock may be issued to a Person other than the Person in whose name such Company Stock Certificate so surrendered is registered if such Company Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such issuance shall have provided all documents required to evidence the payment of any transfer or other Taxes required by reason of the issuance of Parent Common Stock to a Person other than the registered holder of such Company Stock Certificate or shall establish to the satisfaction of Parent that such Taxes are not applicable. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the issuance of any shares in book-entry form representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may

##### Table of Contents

reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Company with respect to such Company Stock Certificate. Upon the making of such affidavit, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Company Stock Certificate the Merger Consideration payable in respect of the shares of Company Common Stock formerly represented by such certificate.

(f) No certificates or scrip or shares representing fractional shares of Parent Common Stock shall be issued upon the exchange of Company Common Stock, and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a stockholder of Parent or a holder of shares of Parent Common Stock. Notwithstanding any other provision of this Agreement, each holder of Company Common Stock (other than Excluded Shares) that is exchanged pursuant to the First Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Company Stock Certificates and Book-Entry Common Shares held by such holder) shall receive, in lieu thereof, cash in dollars (without interest) in an amount, rounded to the nearest cent, equal to the product of:

(i) such fractional part of a share of Parent Common Stock multiplied by

(ii) the volume-weighted average price of Parent Common Stock for the five (5) consecutive trading days ending two (2) trading days prior to the Closing Date as reported by Bloomberg, L.P. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall promptly make such payments to such holders of fractional interests subject to and in accordance with the terms hereof. The payment of cash in lieu of fractional shares of Parent Common Stock is not a separately bargained-for consideration but merely represents a mechanical rounding-off of the fractions in the exchange.

(g) Any portion of the Exchange Fund that remains undistributed to stockholders of the Company as of the date six (6) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not surrendered their Company Stock Certificates to the Exchange Agent in accordance with this Section 1.8 and any holders of Book-Entry Common Shares who have not cashed any check payable to them in accordance with Section 1.9 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions to be paid pursuant to Section 1.8(c), subject to applicable abandoned property law, escheat laws or similar Laws.

(h) Each of the Exchange Agent, Parent, the Surviving Corporation and the Surviving Company shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement (without duplication of any withholding pursuant to Section 5.6 applicable to amounts treated as compensation) such amounts as are required to be deducted or withheld therefrom under the Code and the Treasury Regulations, or any provision of state, local or non-U.S. Law with respect to Taxes or under any other applicable Law.

In addition, and without limiting the generality of the foregoing provisions of this clause (b), for the plan year in which the Effective Time occurs (or if later, during the plan year in which such participation first commences), Parent shall use commercially reasonable efforts to cause: (i) for purposes of each New Plan providing medical, dental, pharmaceutical or vision benefits to any Company Employee, all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Company Employee and his or her covered dependents to the same extent waived or satisfied under the corresponding Company Benefit Plan in which such Company Employee participated immediately prior to the Effective Time and (ii) eligible expenses paid by each Company Employee and his or her covered dependents during the plan year that includes the Effective Time under the Company Benefit Plans that are group health plans to be taken into account for purposes of satisfying the corresponding deductible, coinsurance and maximum out-of-pocket requirements applicable to such Company Employee and his or her covered dependents under the corresponding New Plan that is a group health plan.

To the extent the Company 401(k) Plan is terminated pursuant to the foregoing sentence, as soon as administratively practicable following the Closing Date, the Parent shall provide that each Company Employee that participates in the Company 401(k) Plan immediately prior to the Closing Date shall be eligible to participate in a Parent Benefit Plan that is intended to qualified under Section 401(a) of the Code of Parent or one of its Affiliates (the “Parent 401(k) Plan”) and such Parent 401(k) Plan shall accept “eligible rollover distributions” (as such term is defined under Section 402(c)(4) of the Code) in the form of cash, promissory note (in the case of loans) to the extent allowable under the terms of the Parent 401(k) Plan or any combination thereof, from the Company 401(k) Plan to the extent elected by a Company Employee.

(b) For a period of six (6) years from the Effective Time, the organizational documents of the Surviving Company shall contain provisions no less favorable with respect to elimination of liability, indemnification and advancement of expenses of individuals who were directors and officers of the Company prior to the Effective Time than are set forth, as of the date of this Agreement, in the Company’s certificate of incorporation and bylaws.

policies an annual premium amount in excess of three hundred percent (300%) of the annual premiums currently paid by the Company for such insurance; provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Surviving Company (or Parent on the Surviving Company’s behalf) shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(d) In the event of any claim, action, suit, proceeding or investigation in which any claims are made in respect of which such Indemnified Party would be entitled to indemnification pursuant to Section 5.8(a), any Indemnified Party wishing to claim such indemnification shall notify Parent thereof in writing, but the failure to so notify shall not relieve Parent or the Surviving Company of any liability it may have to such Indemnified Party except to the extent such failure materially prejudices Parent or the Surviving Company. In the event of any such claim, action, suit, proceeding or investigation: (i) Parent or the Surviving Company shall have the right to assume the defense thereof (it being understood that by electing to assume the defense thereof, neither Parent nor the Surviving Company will be deemed to have waived any right to object to the Indemnified Party’s entitlement to indemnification hereunder with respect thereto or assumed any liability with respect thereto), except that if Parent or the Surviving Company elects not to assume such defense or legal counsel for the Indemnified Party advises that there are issues which raise conflicts of interest between Parent or the Surviving Company and the Indemnified Party, the Indemnified Party may retain legal counsel reasonably satisfactory to Parent and to the provider of any insurance obtained in accordance with the foregoing Section 5.8(c), and Parent or the Surviving Company shall pay all reasonable and documented fees, costs and expenses of such legal counsel for the Indemnified Party as statements therefor are received; provided, however, that (1) Parent and the Surviving Company shall be obligated pursuant to this Section 5.8(d) to pay for only one firm of legal counsel for all Indemnified Parties in any jurisdiction unless the use of one legal counsel for such Indemnified Parties would present such legal counsel with a conflict of interest (in which case the fewest number of legal counsels necessary to avoid conflicts of interest shall be used) and (2) the Indemnified Party shall have made an undertaking to repay all such fees, costs or expenses paid by Parent or the Surviving Company if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment that the Indemnified Party is not entitled to be indemnified by Parent or the Surviving Company; (ii) the Indemnified Parties shall cooperate in the defense of any such matter if Parent or the Surviving Company elects to assume such defense; (iii) Parent and the Surviving Company shall not be liable for any settlement effected without their prior written consent and the prior written consent of the provider of any insurance obtained in accordance with the foregoing Section 5.8(c), in each case if Parent or the Surviving Company elects not to assume such defense; and (iv) Parent and the Surviving Company shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnified action of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. Notwithstanding anything herein to the contrary, neither Parent nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any claim, action, suit, proceeding or investigation (and in which indemnification could be sought by Indemnified Parties hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such claim, action, suit, proceeding or investigation or such Indemnified Party otherwise consents in writing.

(e) If Parent or the Surviving Company or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or Entity and shall not be the continuing or surviving corporation or Entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other Entity, then, and in each such case, proper provisions shall be made (whether by operation of law or otherwise) so that the successors and assigns of Parent or the Surviving Company shall assume all of the obligations set forth in this Section 5.8.

(f) The provisions of this Section 5.8:

(i) shall survive the consummation of the Mergers and continue in full force and effect,

(iv) shall not be amended in any manner that is adverse to the Indemnified Parties (including their successors, heirs and legal representatives) without the written consent of the Indemnified Party (including the successors, heirs and legal representatives) affected thereby.

(g) The rights of the Indemnified Parties under this Section 5.8 shall be in addition to any rights such Indemnified Parties may have under the Company Organizational Documents or under any applicable Contracts or Laws in effect on the date of this Agreement and, in the case of such documents and Contracts, disclosed to Parent prior to the execution hereof or as disclosed in the Company SEC Documents, Parent shall, and shall cause the Surviving Company to, honor and perform under all indemnification agreements entered into by the Company or any of the Company Subsidiaries in effect on the date of this Agreement and disclosed to Parent prior to the execution hereof or as disclosed in the Company SEC Documents, and any provisions under any such applicable Contracts (including such indemnification agreements) shall not be amended, repealed or otherwise modified in any manner that would materially adversely affect the rights thereunder of any such individual.

(b) Prior to the Closing, upon Parent’s request, the Company shall use its commercially reasonable efforts to take, or cause to be taken, all actions reasonably necessary to be taken prior to the Closing to enable the delisting of Company Common Stock from the NYSE and the termination of the Company’s registration of Company Common Stock under the Exchange Act, in each case, as soon as practicable following the Effective Time, subject to compliance with the Company’s obligations under the Exchange Act.

Prior to the Effective Time, the Company Board shall approve the disposition of the Company’s equity securities (including derivative securities) in connection with the Mergers by those directors and officers of the Company subject to the reporting requirements of Section 16 of the Exchange Act to the extent necessary for such disposition to be an exempt disposition pursuant to SEC Rule 16b-3.

Section 5.14 Tax Matters.

(a) Each of the Company and Parent will (i) use its commercially reasonable efforts to cause the Mergers, taken together, to qualify and (ii) not take (and will prevent any controlled Affiliate of such party from taking) any action that could reasonably be expected to prevent the Mergers, taken together, from qualifying, in each case, for the Reorganization Treatment. Each of the Company and Parent shall report the Mergers, taken together, as qualifying for the Reorganization Treatment and shall not take any position inconsistent therewith, except to the extent otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

(c) Each of the Company and Parent will (i) notify the other party promptly upon becoming aware of any reason to believe that the Mergers, taken together, may not qualify for the Reorganization Treatment and (ii) provide such information as their relevant equityholders that qualify as “significant holders” may reasonably require to file a statement with their U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3(b).

Section 5.17 Governance. Prior to the Effective Time, Parent shall take all actions as may be necessary to cause the number of directors constituting the Parent Board as of the Effective Time to be increased by two (2) members to a total of ten members. Prior to the date that the Joint Proxy Statement is first filed pursuant to Section 5.2(a), Parent shall offer to interview each of the persons set forth on Section 5.17 of the Parent Disclosure Letter, and following such interviews, select two (2) such persons to be appointed to the Parent Board to fill the vacancies on the Parent Board created by such increase (effective immediately upon the Closing) (collectively, the “Company Directors”). Prior to the Effective Time, the Parent Board shall take all necessary actions for the Company Directors to be appointed to the Parent Board to fill the vacancies on the Parent Board created by such increase (effective immediately upon the Closing). If any such selected Company Director is unable or unwilling to serve, for any reason, as a director on the Parent Board at the Effective Time, Parent shall have the right to designate any other Person set forth on Section 5.17 of the Parent Disclosure Letter to fill a vacancy on the Parent Board created by such increase (effective upon the Closing).

Section 5.18 Financing Cooperation.

(a) On or prior to the Closing Date, Parent shall use its reasonable best efforts to take, or cause to be taken, all actions, and use its reasonable best efforts to do, or cause to be done, all things necessary, proper or advisable to consummate and obtain, or cause its Subsidiaries, as applicable, to consummate and obtain, the Debt Financing on the terms and conditions set forth in the Debt Commitment Letter as promptly as practicable including using its, and causing their Subsidiaries to use their, reasonable best efforts to (i) maintain in full force and effect the Debt Commitment Letter (and to comply with their respective obligations thereunder) until the Closing, (ii) timely (and in any event by the Closing) negotiate and enter into definitive agreements with respect to the facilities contemplated by and to the extent required under the Debt Commitment Letter on the terms and conditions set forth therein, and (iii) satisfy or cause to be waived on a timely basis all conditions to funding applicable to the Parent and its Subsidiaries set forth in the Debt Commitment Letter, or to the extent that the Debt Financing is contemplated to be an Increase (as defined in the Parent Credit Agreement), the Parent Credit Agreement, or such definitive agreements that are within their (or any of their Subsidiaries’) control and otherwise comply with its obligations thereunder. In furtherance and not in limitation of the foregoing, Parent undertakes not to agree to (I) any amendment without the consent of the Company (x) to the Debt Commitment Letter that would reduce the amount of the Debt Financing provided thereunder to an amount less than Parent would need, together with all other sources of funding available to them, to fund the Debt Financing Amounts by the Closing or (y) to the conditions to the funding of the Debt Financing thereunder in a manner that would reasonably be expected to prevent or impede or delay the consummation of the transactions contemplated hereby (collectively, the “Restricted Financing Letter Amendments”) or (II) the termination of the Debt Commitment Letter to the extent doing so could reasonably be expected to prevent or materially impede or delay the consummation of the transactions contemplated hereby, including the ability of Parent to timely pay amounts payable under or in connection with this Agreement; provided that, Parent may replace, amend, supplement or modify the Debt Commitment Letter to the extent not prohibited by this Section 5.18(a) (including to add lenders, lead arrangers, bookrunners, syndication agents or similar entities (or titles with respect to such entities) that have not executed the Debt Commitment Letter as of the date of this Agreement, together with any conforming or ministerial changes related thereto), but only if such replacement, amendment, supplement or modification, individually or in the aggregate, would not result in the occurrence of a Restricted Financing Letter Amendment. Parent shall promptly furnish to the Company true and complete copies of any amendment, replacement, supplement, modification, consent or waiver relating to the Debt Commitment Letter or any definitive agreements relating to the Debt Financing. Upon any such amendment, replacement, supplement, modification, consent or waiver under the Debt Commitment Letter in accordance with this Section 5.18(a), the term “Debt Commitment Letter” (and consequently the terms “Debt Financing” and “Financing” shall mean the Debt Financing contemplated by such Debt Commitment Letter as so replaced, amended, supplemented, modified or waived). In the period between the date of this Agreement and the Closing Date, Parent shall (A) reasonably promptly upon request from the Company, provide the Company updates about the preparation of the financing of the transactions contemplated hereby and (B) promptly inform the Company after becoming aware of any circumstance or event which could reasonably be expected to prevent or impede or delay Parent’s ability to

obtain funds sufficient to fund the Debt Financing Amounts by the Closing. Without prejudice to Parent’s contractual responsibility to pay the amounts when due and payable under or in connection with this Agreement, the Company hereby acknowledges and agrees that, to the extent other financing (or financing commitments) is available to Parent to timely pay the Debt Financing Amounts, Parent may finance the Debt Financing Amounts using such other financing (or financing commitments) or a portion thereof.

(b) Subject to the terms and conditions of this Agreement and using its reasonable best efforts, the Company shall, and shall use its reasonable best efforts to cause each Company Subsidiary and their Representatives to use reasonable best efforts to, provide cooperation in connection with the arrangement of the Debt Financing or any other any debt financing to be incurred in relation to, in contemplation of or as a result of the transactions (the “Financing”) as may be reasonably requested by Parent. Such cooperation shall include reasonable best efforts by the Company and each Company Subsidiary to:

(i) participate in a reasonable number of meetings, presentations, information, drafting or diligence sessions, customary presentations and sessions with prospective debt financing sources and rating agencies, as applicable, in each case on reasonable advance notice, including providing direct contact between appropriate members of senior management, advisors and auditors of the Company, on the one hand, and the actual and potential financing sources and ratings agencies, as applicable, on the other hand;

(ii) (x) to the extent not publicly available, furnish, all historical financials available to the Company and each Company Subsidiary and other information related to the Company and the Company Subsidiaries and any additional financial statements, schedules, business or other financial data relating to the Company and the Company Subsidiaries, in each case, that is customarily included in offering or marketing material for applicable Financing or reasonably necessary for the completion of such Financing and (y) reasonably cooperate with all other marketing efforts, including the preparation of customary authorization and management representation letters, one or more confidential information memoranda or other marketing or syndication materials, and rating agency presentations of Parent and the debt financing sources, in each case in connection with any Financing;

(iii) furnish, at least five (5) Business Days prior to the Closing, such documentation and information as is reasonably requested by Parent at least nine (9) Business Days prior to the Closing in connection with Economic Sanctions/Trade Laws, Money-Laundering Laws, and any other applicable “know your customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act and 31 C.F.R. §1010.230, and if the Company or any Company Subsidiary qualifies as a “legal entity customers” under the Beneficial Ownership Regulation, information regarding the Company or any such Company Subsidiary necessary to complete a Beneficial Ownership Certification with respect to the Company or any such Company Subsidiaries, in each case, to satisfy the conditions precedent to any Financing;

(iv) execute and deliver any credit agreements, pledge and security documents, payoff letters from any third party lenders (or agents therefor), trustees or other holders of Indebtedness of the Company or Company Subsidiaries (or representatives therefor), other definitive financing documents or other reasonably requested certificates or documents customary for transactions of the applicable type; provided that (A) none of the foregoing agreements, letters, documents or certificates shall be executed or delivered except in connection with the Closing and (B) the effectiveness thereof shall be conditioned upon, or become operative after or concurrently with, the occurrence of the Closing (excluding any customary authorization and management representation letters contemplated by Section 5.18(b)(ii) (provided that such customary authorization letters (or the bank information memoranda in which such letters are included) shall include customary language that exculpates the Company and each of the Company Subsidiaries from any liability in connection with the unauthorized use by the recipients thereof of the information set forth in any such bank confidential information memoranda or similar memoranda or report distributed in connection therewith)); and

(v) cooperate with the debt financing sources’ reasonable due diligence investigation and evaluation of the assets (including providing reasonable access as necessary for completion of an initial field

exam, audit or collateral appraisal in connection with the borrowing base for any asset-based loan component of the Financing and any other field exams, commercial finance examinations and inventory, equipment and real property appraisals that may be necessary or customary), properties and cash management (including facilitating the requisite cash management systems required in connection with the asset-based loan component of the Financing).

(c) Notwithstanding the foregoing, nothing in this Section 5.18 shall require the Company or any Company Subsidiary to:

(i) take any action in respect of the Financing to the extent that such action would cause any condition to the Closing set forth in Article VI to fail to be satisfied by the Termination Date or otherwise result in a breach of this Agreement by the Company;

(ii) take any action in respect of the Financing that would conflict with or violate the Company’s any Company Subsidiary’s, or their respective Affiliates’ organizational documents or any applicable Law, or result in the contravention of, or violation of breach of, or default under, any contract to which the Company, any Company Subsidiary, or their respective Affiliates is a party;

(iii) take any action to the extent such action would (A) unreasonably interfere with the business or operations of the Company, any Company Subsidiary or their Affiliates or (B) cause competitive harm to the Company, and Company Subsidiary or their Affiliates if the transactions are not consummated;

(iv) execute and deliver any letter, agreement, document or certificate in connection with the Financing or any corporate action that is not contingent on, or that would be effective prior to, the occurrence of the Closing (excluding any customary authorization and management representation letters contemplated by Section 5.18(b)(ii) (provided that such customary authorization letters (or the bank information memoranda in which such letters are included) shall include customary language that exculpates the Company and each of the Company Subsidiaries from any liability in connection with the unauthorized use by the recipients thereof of the information set forth in any such bank confidential information memoranda or similar memoranda or report distributed in connection therewith));

(v) pay any commitment fee or other fee or payment to obtain consent or incur any liability with respect to or cause or permit any lien to be placed on any of their respective assets in connection with the Financing prior to the Closing Date;

(vi) provide access to or disclose information where the Company determines (in the Company’s reasonable judgement after consultation with its outside legal counsel) that such access or disclosure would reasonably be expected to result in the loss or waiver of any attorney-client privilege or contravene any applicable Law or Contract (provided that the Company shall use reasonable best efforts to make substitute arrangements or permit such disclosure in a manner that would not result in the loss or waiver of any such attorney-client privilege and provide such information or access to the maximum extent possible without running afoul of the foregoing restrictions); or

(vii) subject any of the Company’s, any Company Subsidiaries’ or their respective Affiliates’ respective directors, managers, officers or employees to any actual or potential personal liability (as opposed to liability in his or her capacity as a director, manager, officer or employee of such person).

(d) Parent shall promptly, upon request by the Company, reimburse the Company for all reasonable and documented out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred by the Company or the Company Subsidiaries in connection with the cooperation of the Company and the Company Subsidiaries contemplated by this Section 5.18 and shall indemnify and hold harmless the Company, the Company Subsidiaries and their respective Representatives from and against any and all losses, damages, claims, costs or expenses actually suffered or incurred by any of them of any type in connection with the arrangement of any Financing and any information used in connection therewith, in each case, except to the extent such losses, damages, claims, costs or expenses result from (i) the gross negligence, bad faith or willful misconduct of the Company, any of the Company Subsidiaries or their respective Representatives, as determined by a court of

competent jurisdiction by final and nonappealable judgment, (ii) the material breach of this Agreement by the Company, any of the Company Subsidiaries or their respective Representatives or (iii) any material misstatement in, or omission of a material fact from, information provided in writing hereunder by the Company, any of the Company Subsidiaries or their respective Representatives for use in connection herewith or with the Financing that results in such information being materially misleading in light of the circumstances under which such information was provided and the foregoing obligations shall survive termination of this Agreement.

(e) The Company hereby consents, on behalf of itself and the Company Subsidiaries, to use of the Company’s and the Company Subsidiaries’ logos in connection with the Financing; provided that such logos are used in a manner that is not intended to or reasonably likely to harm or disparage the Company’s or the Company Subsidiaries’ reputation or goodwill.

(f) All material non-public information provided by the Company or any of the Company Subsidiaries or any of their respective Representatives pursuant to this Section 5.18 shall be kept confidential in accordance with the Confidentiality Agreement, except that Parent shall be permitted to disclose such information to the debt financing sources, other potential sources of capital and prospective lenders and investors entering into customary confidentiality undertakings with respect to such information (including through a notice and undertaking in a form customarily used in confidential information memoranda for senior credit facilities).

(g) Parent acknowledges and agrees that, subject to Section 5.18(h), the obligations to perform its agreements hereunder, including to consummate the Closing, are not conditioned on obtaining of the Financing or any alternative financing or on the performance of any party to any financing commitment letter.

(h) Notwithstanding anything to the contrary in this Agreement, for all purposes of this Agreement (including the condition set forth in Section 6.2(a) as it applies to the Company’s obligations under this Section 5.18), the Company’s obligations under this Section 5.18 shall be deemed satisfied unless (i) the Company has materially breached this Agreement and (ii) such material breach is the consequence of an act or omission taken or omitted to be taken that the Company intentionally takes (or intentionally fails to take) with the knowledge that such act or omission would cause a material breach of such agreement or covenant, in each case, to the extent that such material breach (A) causes the conditions in Section 3 of the Debt Commitment Letter (or substantially similar conditions in any replacement to such Debt Commitment Letter described below) to not be satisfied solely as they relate to the Company and is (B) the primary cause of Parent being unable to obtain the proceeds of the Debt Financing (or replacement to the Debt Financing) at or prior to the Closing.

(B) Parent, Merger Sub and LLC Sub against the Company and its Subsidiaries and any of their respective former, current or future controlling persons, directors, officers, employees, agents, members, managers, general or limited partners or assignees, or stockholders or equityholders, Representatives or Affiliates for any losses, damages, fees, costs, expenses or other liabilities suffered or incurred as a result of the failure of the Mergers to be consummated and upon payment of such amount, none of the Company and its Subsidiaries or any of their respective former, current or future controlling persons, directors, officers, employees, agents, members, managers, general or limited partners or assignees, or stockholders or equityholders, Representatives or Affiliates shall have any further liability or obligation relating to or arising out of this Agreement or the Mergers or the transactions contemplated by this Agreement; provided that no such payment shall relieve the Company of any liability or damages to any Parent Party as a result of fraud or a Willful and Material Breach of any covenant, agreement or obligation (in which case only the Company shall be liable for damages for such fraud or Willful and Material Breach).

If the Company or Parent is entitled pursuant to this Agreement to both payment of any monetary damages (including monetary damages in respect of any fraud or Willful and Material Breach of the other parties) and payment of the Termination Fee or Expenses, as applicable, then the Termination Fee or Expenses to the extent paid shall reduce the damages to which such party is entitled (if any) on a dollar-for-dollar basis. For the avoidance of doubt and notwithstanding anything to the contrary, payment of the Termination Fee shall be in lieu of, and not in addition to, the reimbursement of Expenses.

DNOW Inc.

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to DNOW Inc. (the “Company”) of the exchange ratio (the “Exchange Ratio”) of 0.9489 shares of common stock, par value $0.01 per share (the “Company Common Stock”), of the Company to be issued in exchange for each outstanding share of common stock, par value $0.01 per share (the “MRC Common Stock”), of MRC Global Inc. (“MRC”) (other than shares of MRC Common Stock held by the Company, MRC or any of their respective subsidiaries (collectively, the “Excluded Shares”)) pursuant to the Agreement and Plan of Merger, dated as of June 26, 2025 (the “Agreement”), by and among the Company, Buck Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), Stag Merger Sub, LLC, a wholly owned subsidiary of the Company (“LLC Sub”), and MRC. The Agreement provides that, among other things, (a) Merger Sub will be merged with and into MRC, with MRC continuing as the surviving entity (the “First Merger”); and (b) MRC will then be merged with and into LLC Sub, with LLC Sub as the surviving entity and a direct, wholly owned subsidiary of the Company. As a result of the First Merger, each issued and outstanding share of MRC Common Stock (other than Excluded Shares) will be converted into the right to receive a number of shares of Company Common Stock equal to the Exchange Ratio.

Goldman Sachs & Co. LLC and its affiliates are engaged in advisory, underwriting, lending and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs & Co. LLC and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Company, MRC and any of their respective affiliates and third parties or any currency or commodity that may be involved in the transactions contemplated by the Agreement (the “Transaction”). Goldman Sachs Investment Banking has an existing lending relationship with MRC and/or its subsidiaries. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the Transaction. We expect to receive fees for our services in connection with the Transaction, the principal portion of which is contingent upon consummation of the Transaction, and the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement. At your request, an affiliate of Goldman Sachs & Co. LLC has entered into financing commitments to provide the Company with a backstop to the accordion of the Company’s existing asset-based loan in connection with the consummation of the Transaction, subject to the terms of such commitments, and pursuant to which one or more affiliates of Goldman Sachs & Co. LLC expects to receive compensation. We have provided certain financial advisory and/or underwriting services to MRC and/or its affiliates from time to time for which Goldman Sachs Investment Banking has received, and may receive, compensation, including having acted as documentation

agent in connection with a term loan B offering for MRC in November 2024. We may also in the future provide financial advisory and/or underwriting services to the Company, MRC and their respective affiliates for which Goldman Sachs Investment Banking may receive compensation.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and MRC for the five years ended December 31, 2024; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and MRC for the quarter ended March 31, 2025; certain other communications from the Company and MRC to their respective stockholders; certain publicly available research analyst reports for the Company and MRC; certain internal financial analyses and forecasts for MRC prepared by its management and certain internal financial analyses and forecasts for the Company standalone and pro forma for the Transaction, including certain operating synergies projected by the management of the Company to result from the Transaction (the “Synergies”), as prepared by the management of the Company, and in each case, approved for our use by the Company (the “Forecasts”); and certain internal forecasts related to the expected utilization by the Company of certain net operating loss carryforwards and tax credits, as prepared by the Company’s management and approved for our use by the Company (the “NOL Forecasts”). We have also held discussions with members of the senior managements of the Company and MRC regarding their assessment of the past and current business operations, financial condition and future prospects of MRC and with the members of senior management of the Company regarding their assessment of the past and current business operations, financial condition and future prospects of the Company and the strategic rationale for, and the potential benefits of, the Transaction; reviewed the reported price and trading activity for the shares of Company Common Stock and the shares of MRC Common Stock; compared certain financial and stock market information for the Company and MRC with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations; and performed such other studies and analyses, and considered such other factors, as we deemed appropriate.

For purposes of rendering this opinion, we have, with your consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, us, without assuming any responsibility for independent verification thereof. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, and the NOL Forecasts have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company. We have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of the Company or MRC or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or MRC or on the expected benefits of the Transaction in any way meaningful to our analysis. We also have assumed that the Transaction will be consummated on the terms set forth in the Agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, or the relative merits of the Transaction as compared to any strategic alternatives that may be available to the Company; nor does it address any legal, regulatory, tax or accounting matters. This opinion addresses only the fairness from a financial point of view to the Company, as of the date hereof, of the Exchange Ratio pursuant to the Agreement. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Transaction or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into or amended in connection with the Transaction, including the fairness of the

Transaction to, or any consideration received in connection therewith by, the holders of any class of securities, creditors, or other constituencies of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company or MRC, or any class of such persons in connection with the Transaction, whether relative to the Exchange Ratio pursuant to the Agreement or otherwise. We are not expressing any opinion as to the prices at which shares of Company Common Stock or MRC Common Stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on the Company, MRC or the Transaction, or as to the impact of the Transaction on the solvency or viability of the Company or MRC or the ability of the Company or MRC to pay their respective obligations when they come due. Our opinion is necessarily based on economic, monetary,

market and other conditions as in effect on, and the information made available to us as of, the date hereof and we assume no responsibility for updating, revising or reaffirming this opinion based on circumstances, developments or events occurring after the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Company Common Stock should vote with respect to such Transaction or any other matter. This opinion has been approved by a fairness committee of Goldman Sachs & Co. LLC.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the Company.

Very truly yours,

EXECUTION VERSION

June 26, 2025

The Board of Directors

MRC Global Inc.

Fulbright Tower

1301 McKinney Street, Suite 2300

Houston, TX 77010-3035

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of common stock, par value $0.01 per share (the “Company Common Stock”), of MRC Global Inc. (the “Company”) of the Exchange Ratio (as defined below) in the proposed First Merger (as defined below) of the Company with a wholly-owned subsidiary of DNOW Inc. (the “Acquiror”). Pursuant to the Agreement and Plan of Merger, dated as of June 26, 2025 (the “Agreement”), among the Company, the Acquiror, Buck Merger Sub, Inc., a wholly owned subsidiary of the Acquiror (“Merger Sub”) and Stag Merger Sub, LLC, a wholly owned subsidiary of the Acquiror (“LLC Sub”), (i) Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation (the “Surviving Corporation”), and each outstanding share of Company Common Stock, other than the Excluded Shares (as defined in the Agreement), will be converted into the right to receive 0.9489 shares (the “Exchange Ratio”) of the Acquiror’s common stock, par value $0.01 per share (the “Acquiror Common Stock”), with cash paid in lieu of any fractional shares of the Acquiror Common Stock, subject to the terms and conditions of the Agreement (such merger, the “First Merger”) and (ii) immediately thereafter, the Surviving Corporation will merge with and into LLC Sub, with LLC Sub continuing as the surviving company (the “Surviving Company” and, such merger, the “Second Merger” and, together with the First Merger, the “Transaction”).

In connection with preparing our opinion, we have (i) reviewed the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the Acquiror and the industries in which they operate; (iii) compared the financial and operating performance of the Company and the Acquiror with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Company Common Stock and the Acquiror Common Stock and certain publicly traded securities of such other companies; (iv) reviewed certain internal financial analyses and forecasts prepared by the management of the Company and the Acquiror relating to their respective businesses (with the Acquiror’s forecasts subject to adjustment by the Company), as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the Transaction (the “Synergies”); and (v) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company and the Acquiror with respect to certain aspects of the Transaction, and the past and current business operations of the Company and the Acquiror, the financial condition and future prospects and operations of the Company and the Acquiror, the effects of the Transaction on the financial condition and future prospects of the Company and the Acquiror, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company and the Acquiror or otherwise

reviewed by or for us. We have not independently verified any such information or its accuracy or completeness and, pursuant to our engagement letter with the Company, we did not assume any obligation to undertake any such independent verification. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company or the Acquiror under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom, including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Company and the Acquiror to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will qualify as a tax-free reorganization for United States federal income tax purposes and will be consummated as described in the Agreement. We have also assumed that the representations and warranties made by the Company, the Acquiror, Merger Sub and LLC Sub in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or the Acquiror or on the contemplated benefits of the Transaction.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, to the holders of the Company Common Stock of the Exchange Ratio in the proposed First Merger and we express no opinion as to the fairness of any consideration to be paid in connection with the Transaction to the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Exchange Ratio applicable to the holders of the Company Common Stock in the First Merger or with respect to the fairness of any such compensation. We are expressing no opinion herein as to the price at which the Company Common Stock or the Acquiror Common Stock will trade at any future time.

We note that we were not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of the Company or any other alternative transaction.

We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services, a substantial portion of which will become payable only if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. Please be advised that during the two years preceding the date of this letter, neither we nor our affiliates have had any material financial advisory or other material commercial or investment banking relationships with the Acquiror. During the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with the Company, for which we and such affiliates have received customary compensation. Such services during such period have included acting as joint lead arranger and joint bookrunner on a credit facility in November 2024. In addition, our commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of the Company, for which it receives customary compensation or other financial benefits. In addition, we and our affiliates hold, on a proprietary basis, less than 1% of the outstanding common stock of each of the Company and the Acquiror. In the ordinary course of our businesses, we and our affiliates actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of the Company or the Acquiror for our own account or for the accounts of customers and, accordingly, we likely hold long or short positions in such securities or other financial instruments.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. | Indemnification of Directors and Officers.

DNOW is organized under the laws of Delaware. Reference is made to Section 102(b)(7) of the DGCL, which enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director’s fiduciary duty, except (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) pursuant to Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends or unlawful stock purchases or redemptions; or (4) for any transaction from which a director derived an improper personal benefit.

Reference is also made to Section 145 of the DGCL, which provides that a corporation may indemnify any person, including an officer or director, who was or is, or is threatened to be made, party to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the corporation’s best interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify any officer or director in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses that such officer or director actually and reasonably incurred in connection therewith.

In accordance with Section 102(b)(7) of the DGCL, the DNOW certificate of incorporation provides that no director shall be personally liable to DNOW or any DNOW stockholder for monetary damages resulting from breaches of its fiduciary duty as a director, except to the extent such limitation on or exemption from liability is not permitted under the DGCL unless he or she violated their duty of loyalty to DNOW or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing or intentional violation of law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived improper personal benefit from their actions as directors. The effect of this provision of the DNOW certificate of incorporation is to eliminate DNOW’s rights and those of its stockholders (through stockholders’ derivative suits on DNOW’s behalf) to recover monetary damages against a director for breach of the fiduciary duty of care as a director, including breaches resulting from negligent or grossly negligent behavior, except, as restricted by Section 102(b)(7) of the DGCL. However, this provision does not limit or eliminate DNOW’s rights or the rights of any DNOW stockholder to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s duty of care.

If the DGCL is amended to authorize corporate action further eliminating or limiting the liability of directors, then, in accordance with the DNOW certificate of incorporation, the liability of DNOW’s directors to it or its stockholders will be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Any repeal or amendment of provisions of the DNOW certificate of incorporation limiting or eliminating the liability of directors, whether by DNOW stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits DNOW to further limit or eliminate the liability of directors on a retroactive basis.

##### Table of Contents

The DNOW certificate of incorporation also provides that DNOW will, to the fullest extent authorized or permitted by applicable law, indemnify its current and former officers and directors, as well as those persons who, while serving as its directors or officers, are or were serving, at DNOW’s request, as directors, officers, employees or agents of another entity, trust or other enterprise, including service with respect to an employee benefit plan, in connection with any threatened, pending or completed proceeding, whether civil, criminal, administrative or investigative, against all expense, liability and loss (including, without limitation, attorney’s fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by any such person in connection with any such proceeding. Notwithstanding the foregoing, under DNOW’s bylaws a person eligible for indemnification pursuant to the DNOW certificate of incorporation will be indemnified by DNOW in connection with a proceeding initiated by such person only if such proceeding was authorized by the DNOW board, except for proceedings to enforce rights to indemnification.

The right to indemnification conferred by the DNOW certificate of incorporation is a contract right that includes the right to be paid by DNOW the expenses incurred in defending or otherwise participating in any proceeding referenced above in advance of its final disposition, provided, however, that if the DGCL requires, an advancement of expenses incurred by DNOW’s officer or director (solely in his or her capacity as an officer or director of DNOW) will be made only upon delivery to DNOW of an undertaking, by or on behalf of such officer or director, to repay all amounts so advanced if it is ultimately determined that such person is not entitled to be indemnified for such expenses under the DNOW certificate of incorporation or otherwise.

The rights to indemnification and advancement of expenses will not be deemed exclusive of any other rights which any person covered by the DNOW certificate of incorporation may have or hereafter acquire under law, the DNOW certificate of incorporation, DNOW bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

Any repeal or amendment of provisions of the DNOW certificate of incorporation affecting indemnification rights, whether by DNOW stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits DNOW to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision. The DNOW certificate of incorporation will also permit DNOW, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than those specifically covered by the DNOW certificate of incorporation.

DNOW bylaws include the provisions relating to advancement of expenses and indemnification rights consistent with those set forth in the DNOW certificate of incorporation. In addition, the DNOW bylaws provide for a right of indemnity to bring a suit in the event a claim for indemnification or advancement of expenses is not paid in full by DNOW within a specified period of time. The DNOW bylaws also permit DNOW to purchase and maintain insurance, at its expense, to protect it and/or any director, officer, employee or agent of DNOW or another entity, trust or other enterprise against any expense, liability or loss, whether or not it would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Any repeal or amendment of provisions of the DNOW bylaws affecting indemnification rights, whether by the DNOW board, DNOW stockholders or by changes in applicable law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits DNOW to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing thereunder with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

DNOW has entered into indemnity agreements with each of its officers and directors. These agreements require it to indemnify these individuals to the fullest extent permitted under Delaware law and to advance expenses incurred as a result of any proceeding against them to which they could be indemnified.

Until the six-year anniversary date of the Effective Time, neither DNOW nor Merger Sub will amend, repeal or otherwise modify any provision in the organizational documents of the surviving corporation or any of its subsidiaries in any manner that would affect adversely the rights of any indemnified person to indemnification, exculpation and advancement except to the extent required by applicable law. DNOW shall, and shall cause the surviving entity and its subsidiaries to, fulfill and honor any indemnification, expense advancement, or exculpation agreements between MRC Global or any of its subsidiaries and any of its officers, directors existing and in effect immediately prior to the Effective Time.

DNOW and the surviving corporation will cause to be put in place, and DNOW will fully prepay immediately prior to the Effective Time, “tail” insurance policies with a claims reporting or discovery period of at least six years from the Effective Time (the “tail period”) from an insurance carrier with the same or better credit rating as MRC Global’s current insurance carrier with respect to directors’ and officers’ liability insurance (“D&O insurance”) in an amount and scope at least as favorable as MRC Global’s existing policies with respect to matters, acts or omissions existing or occurring at, prior to, or after the Effective Time; provided, however, that in no event shall the aggregate cost of the D&O insurance exceed during the tail period 300% of the current aggregate annual premium paid by MRC Global for such purpose; and provided, further, that if the cost of such insurance coverage exceeds such amount, the surviving entity shall obtain a policy with the greatest coverage reasonably available for a cost not exceeding such amount.

II-4

##### Table of Contents

| ii. | to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

| iii. | to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement.

| 2) | That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

| 3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

| 4) | If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in this registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of this registration statement or made in a document incorporated or deemed incorporated by reference into this registration statement or prospectus that is part of this registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in this registration statement or prospectus that was part of this registration statement or made in any such document immediately prior to such date of first use.

| 5) | That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

| i. | any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

| ii. | any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

| iii. | the portion of any other free writing prospectus relating to the offering containing material in-formation about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

| iv. | any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) | The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to

II-5

##### Table of Contents

| Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) | The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(d) | The registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (c) above, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to this registration statement and will not be used until such amendment is effective, and that, for the purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) | Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(f) | The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request.

(g) | The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
