ONEOK, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our accompanying unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC. These statements have been prepared in accordance with GAAP and reflect all adjustments that, in our opinion, are necessary for a fair statement of the results for the interim periods presented. All such adjustments are of a normal recurring nature. The 2022 year-end Consolidated Balance Sheet data was derived from our audited Consolidated Financial Statements but does not include all disclosures required by GAAP. These unaudited Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements in our Annual Report.
Recently Issued Accounting Standards Update - Changes to GAAP are established by the Financial Accounting Standards Board (FASB) in the form of ASUs to the FASB Accounting Standards Codification. We consider the applicability and impact of all ASUs. ASUs not discussed herein or in our Annual Report were assessed and determined to be either not applicable or clarifications of ASUs previously issued. There have been no new accounting pronouncements that have become effective or have been issued that are of significance or potential significance to us.
B. MEDFORD INCIDENT
On July 9, 2022, a fire occurred at our 210 MBbl/d Medford, Oklahoma, natural gas liquids fractionation facility. Beginning in August 2022, we developed claims related to the Medford incident and recorded accruals for the expected insurance recoveries. We assessed incurred costs and lost earnings related to business interruption and property damage to our facility, as well as timing of recognition under applicable insurance recovery guidance, and recorded accruals of $151 million in 2022 for insurance recoveries that offset our incurred costs and losses.
On January 9, 2023, we reached an agreement with our insurers to settle all claims for physical damage and business interruption related to the Medford incident. Under the terms of the settlement agreement, we agreed to resolve the claims for total insurance payments of $930 million, $100 million of which was received in 2022. The remaining $830 million was received in the first quarter 2023. The proceeds serve as settlement for property damage, business interruption claims to the date of the settlement and as payment in lieu of future business interruption insurance claims.
In the first quarter 2023, we applied the $830 million received to our outstanding insurance receivable at December 31, 2022, of $51 million, and recorded an operational gain for the remaining $779 million. We classified proceeds received within the Consolidated Statement of Cash Flows based on our assessment of the nature of the loss (property and business interruption) included in the settlement.
C. FAIR VALUE MEASUREMENTS
Determining Fair Value - For our fair value measurements, we utilize market prices, third-party pricing services, present value methods and standard option valuation models to determine the price we would receive from the sale of an asset or the transfer of a liability in an orderly transaction at the measurement date. We measure the fair value of a group of financial assets and liabilities consistent with how a market participant would price the net risk exposure at the measurement date. Determining the appropriate classification of our fair value measurements within the fair value hierarchy requires management’s judgment regarding the degree to which market data is observable or corroborated by observable market data. We categorize derivatives based on the lowest level input that is significant to the fair value measurement in its entirety. Our valuation techniques and inputs are consistent with those discussed in Note A of the Notes to Consolidated Financial Statements in our Annual Report.

Recurring Fair Value Measurements - The following tables set forth our recurring fair value measurements as of the dates indicated:

(a) - Derivative assets and liabilities are presented in our Consolidated Balance Sheet on a net basis. We net derivative assets and liabilities when a legally enforceable master-netting arrangement exists between the counterparty to a derivative contract and us. At March 31, 2023, we posted no cash and held cash of $17 million from various counterparties, which offsets our derivative net asset position under master netting arrangements as shown in the table above.

(a) - Derivative assets and liabilities are presented in our Consolidated Balance Sheet on a net basis. We net derivative assets and liabilities when a legally enforceable master-netting arrangement exists between the counterparty to a derivative contract and us. At December 31, 2022, we held no cash and posted $9 million of cash with various counterparties, which is included in other current assets in our Consolidated Balance Sheet.
The following table sets forth a reconciliation of our Level 3 fair value measurements for the periods indicated:

|  |  | Three Months Ended
|  |  | March 31,
Derivative Assets (Liabilities) |  |  |  |  | 2023 |  | 2022

Net liabilities at end of period |  |  |  |  | $ | — |  |  | $ | (190) |

(a) - Included in commodity sales revenues/cost of sales and fuel in our Consolidated Statements of Income.
(b) - Included in change in fair value of derivatives in our Consolidated Statements of Comprehensive Income.
During the year ended December 31, 2022, we transferred out of Level 3 commodity derivatives associated with certain locations for both NGL and natural gas basis swaps, principally due to improved transparency of market prices as a result of the volume and frequency of transactions in these markets. We consider the valuation of these commodity derivatives, which are transacted through a clearing broker and valued with an unadjusted published price from an exchange, as a Level 2 valuation.
Other Financial Instruments - The approximate fair value of cash and cash equivalents, accounts receivable, accounts payable and short-term borrowings is equal to book value due to the short-term nature of these items. Our cash and cash equivalents are
13

Table of Contents
composed of bank and money market accounts and are classified as Level 1. Our short-term borrowings are classified as Level 2 since the estimated fair value of the short-term borrowings can be determined using information available in the commercial paper market. We have investments associated with our supplemental executive retirement plan and nonqualified deferred compensation plan that are carried at fair value and primarily are composed of exchange-traded mutual funds classified as Level 1.
The estimated fair value of our consolidated long-term debt, including current maturities, was $12.6 billion and $12.7 billion at March 31, 2023, and December 31, 2022, respectively. The book value of our consolidated long-term debt, including current maturities, was $13.2 billion and $13.6 billion at March 31, 2023, and December 31, 2022, respectively. The estimated fair value of the aggregate senior notes outstanding was determined using quoted market prices for similar issues with similar terms and maturities. The estimated fair value of our consolidated long-term debt is classified as Level 2.
D. RISK-MANAGEMENT AND HEDGING ACTIVITIES USING DERIVATIVES
Risk-management Activities - We are sensitive to changes in natural gas, crude oil and NGL prices, principally as a result of contractual terms under which these commodities are processed, purchased and sold. We are also subject to the risk of interest-rate fluctuation in the normal course of business. We use physical-forward purchases and sales and financial derivatives to secure a certain price for a portion of our natural gas, condensate and purity NGLs; to reduce our exposure to commodity price and interest-rate fluctuations; and to achieve more predictable cash flows. We follow established policies and procedures to assess risk and approve, monitor and report our risk-management activities. We have not used these instruments for trading purposes.
Commodity price risk - Commodity price risk refers to the risk of loss in cash flows and future earnings arising from adverse changes in the price of natural gas, NGLs and condensate. We may use commodity derivative instruments to reduce the near-term commodity price risk associated with a portion of our forecasted purchases and sales of commodities. Our exposure to commodity price risk is consistent with that discussed in our Annual Report.
Interest-rate risk - We may manage interest-rate risk through the use of fixed-rate debt, floating-rate debt and interest-rate swaps. Interest-rate swaps are agreements to exchange interest payments at some future point based on specified notional amounts. At March 31, 2023, and December 31, 2022, we had forward-starting interest-rate swaps with notional amounts totaling $375 million to hedge the variability of interest payments on a portion of our forecasted debt issuances. All of our interest-rate swaps are designated as cash flow hedges.
Fair Values of Derivative Instruments - The following table sets forth the fair values of our derivative instruments presented on a gross basis as of the dates indicated:

|  |  | March 31, 2023 |  | December 31, 2022

Revenue earned and accounts receivable from, and accounts payable to, our equity-method investees were not material.
We have an operating agreement with Roadrunner that provides for reimbursement or payment to us for management services and certain operating costs. Reimbursements and payments from Roadrunner included in operating income in our Consolidated Statements of Income for all periods presented were not material.
J. COMMITMENTS AND CONTINGENCIES
Environmental Matters and Pipeline Safety - The operation of pipelines, plants and other facilities for the gathering, processing, fractionation, transportation and storage of natural gas, NGLs, condensate and other products is subject to numerous and complex laws and regulations pertaining to health, safety and the environment. As an owner and/or operator of these facilities, we must comply with laws and regulations that relate to air and water quality, hazardous and solid waste management and disposal, cultural resource protection and other environmental and safety matters. The cost of planning, designing, constructing and operating pipelines, plants and other facilities must incorporate compliance with these laws, regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures, including citizen suits, which can include the assessment of monetary penalties, the imposition of remedial requirements and the issuance of injunctions or restrictions on operation or construction. Management does not believe that, based on currently known information, a material risk of noncompliance with these laws and regulations exists that will affect adversely our consolidated results of operations, financial condition or cash flows.
Legal Proceedings - We are a party to various legal proceedings that have arisen in the normal course of our operations. While the results of these proceedings cannot be predicted with certainty, we believe the reasonably possible losses from such proceedings, individually and in the aggregate, are not material. Additionally, we believe the probable final outcome of such proceedings will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.
K. REVENUES
Contract Assets and Contract Liabilities - Our contract asset balances at the beginning and end of the period primarily relate to our firm service transportation contracts with tiered rates, which are not material. Our contract liabilities at the beginning and end of the period primarily represent deferred revenue on storage contracts and deferred revenue on contributions in aid of construction received from customers, which are not material.
Receivables from Customers and Revenue Disaggregation - Substantially all of the balances in accounts receivable on our Consolidated Balance Sheets at March 31, 2023, and December 31, 2022, relate to customer receivables. Revenue sources are disaggregated in Note L.
Transaction Price Allocated to Unsatisfied Performance Obligations - We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) variable consideration on contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
19

Table of Contents
The following table presents aggregate value allocated to unsatisfied performance obligations as of March 31, 2023, and the amounts we expect to recognize in revenue in future periods, related primarily to firm transportation and storage contracts with remaining contract terms ranging from one month to 22 years:

Expected Period of Recognition in Revenue |  | (Millions of dollars)
Remainder of 2023 |  | $ | 328 |
2024 |  | 376 |
2025 |  | 284 |
2026 |  | 271 |
2027 and beyond |  | 874 |
Total estimated transaction price allocated to unsatisfied performance obligations |  | $ | 2,133 |

The table above excludes variable consideration allocated entirely to wholly unsatisfied performance obligations, wholly unsatisfied promises to transfer distinct goods or services that are part of a single performance obligation and consideration we determine to be fully constrained. The amounts we determined to be fully constrained relate to future sales obligations under long-term sales contracts where the transaction price is not known and minimum volume agreements, which we consider to be fully constrained until invoiced.
L. SEGMENTS
Segment Descriptions - Our operations are divided into three reportable business segments as follows:
• our Natural Gas Gathering and Processing segment gathers, treats and processes natural gas;
• our Natural Gas Liquids segment gathers, treats, fractionates and transports NGLs and stores, markets and distributes purity NGLs; and
• our Natural Gas Pipelines segment transports and stores natural gas.
Other and eliminations consist of corporate costs, the operating and leasing activities of our headquarters building and related parking facility, the activity of our wholly owned captive insurance company and eliminations necessary to reconcile our reportable segments to our Consolidated Financial Statements.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis should be read in conjunction with our unaudited Consolidated Financial Statements and the Notes to Consolidated Financial Statements in this Quarterly Report, as well as our Annual Report.
RECENT DEVELOPMENTS
Please refer to the “Financial Results and Operating Information” and “Liquidity and Capital Resources” sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Quarterly Report for additional information.
Market Conditions and Business Update - We experienced increased volumes in the first quarter 2023, compared with the first quarter 2022, due primarily to increased producer activity across our operations. In the remainder of 2023, we expect to benefit from the completion of our Demicks Lake III natural gas processing plant and our MB-5 fractionator, highlighting our extensive and integrated assets that are located in, and connected to, some of the most productive shale basins in the United States. Although the energy industry has experienced many commodity cycles, we have positioned ourselves to reduce exposure to direct commodity price volatility. Each of our three reportable segments are primarily fee-based, and we expect our consolidated earnings to be approximately 90% fee-based in 2023. While our Natural Gas Gathering and Processing segment’s earnings are primarily fee-based, we have direct commodity price exposure related primarily to fee with POP contracts, and we have hedged approximately 70% of our forecasted equity volumes for the remainder of 2023. In addition, our Natural Gas Gathering and Processing and Natural Gas Liquids segments are exposed to volumetric risk as a result of drilling and completion activity, severe weather disruptions, operational outages, global crude oil, NGL and natural gas demand, changes in gas-to-oil ratios and normal volumetric well declines. Our Natural Gas Pipelines segment is not exposed to significant volumetric risk due to nearly all of our capacity being subscribed under long-term, firm fee-based contracts.
Medford Incident - On July 9, 2022, a fire occurred at our 210 MBbl/d Medford, Oklahoma, natural gas liquids fractionation facility. On January 9, 2023, we reached an agreement with our insurers to settle all claims for physical damage and business interruption related to the Medford incident. Under the terms of the settlement agreement, we agreed to resolve the claims for total insurance payments of $930 million, $100 million of which was received in 2022. The remaining $830 million was received in the first quarter 2023, resulting in a one-time settlement gain of $779 million. The proceeds serve as settlement for property damage, business interruption claims to the date of settlement and as payment in lieu of future business interruption insurance claims.
In the first quarter 2023, the Medford incident resulted in an increase in operating income and adjusted EBITDA of $733 million, compared with the same quarter in the prior year, due to the settlement gain of $779 million, which was offset partially by $46 million of third-party fractionation costs. We expect our cash from operations in the remainder of 2023 and in 2024 to be impacted by incurred costs resulting from the Medford incident for which we will no longer receive business interruption proceeds.
Due to market demand and a more favorable completion schedule, we announced plans to construct a new 125 MBbl/d MB-6 NGL fractionator in Mont Belvieu, Texas, instead of rebuilding our Medford NGL fractionator at this time. The MB-6
23

Table of Contents
fractionator will produce purity ethane instead of the ethane/propane mix previously produced at the Medford facility. The 125 MBbl/d capacity of the MB-6 fractionator is expected to be economically comparable to the capacity lost at Medford. In addition, our 125 MBbl/d MB-5 NGL fractionator was completed early in t he second quarter of 2023, which will reduce the need for third-party fractionation while the new MB-6 fractionator is being constructed.
Sustainability and Social Responsibility - In 2023, we qualified for inclusion in the S&P Global Sustainability Yearbook for the third consecutive year, ranking in the top 10% of the Oil and Gas Storage and Transportation industry and being recognized as an Industry Mover. We continue to look for ways to reduce our environmental impact and utilize more efficient technologies. We are evaluating the development of renewable energy and low-carbon projects, including opportunities that may complement our midstream assets and expertise.
Natural Gas - In our Natural Gas Gathering and Processing segment, processed volumes increased in the first quarter 2023, compared with the first quarter 2022, due primarily to increased producer activity in the Rocky Mountain and Mid-Continent regions. In the remainder of 2023, we expect to benefit from our 200 MMcf/d Demicks Lake III natural gas processing plant, which was completed in the first quarter 2023, and is supported by acreage dedications with primarily fee-based contracts.
In our Natural Gas Pipelines segment, continued demand from local distribution companies, electric-generation facilities and large industrial companies supported low-cost expansion projects that position us well to provide additional services to our customers. We are currently expanding the injection capabilities of our Oklahoma natural gas storage facilities which will allow us to utilize and subscribe an additional 4 Bcf of our existing storage capacity, with expected completion in the second quarter 2023. We have subscribed 100% of the incremental 4 Bcf of storage capacity through 2027 and 90% through 2029. In addition, we have begun the electrification of certain compression assets on Viking to improve the reliability of our operations while lowering our Scope 1 emissions from this equipment. Viking will seek to recover its investment in the project through a proposed change in rates expected to be filed in third quarter 2023.
NGLs - In our Natural Gas Liquids segment, we benefited from increased volumes in the first quarter 2023, compared with the first quarter 2022, due primarily to increased production in the Permian Basin and Rocky Mountain region, offset partially by lower ethane volumes in the Mid-Continent and Rocky Mountain regions due to ethane economics as described below. In the remainder of 2023, we expect to benefit from our 125 MBbl/d MB-5 fractionator, which was completed early in the second quarter 2023.
Ethane Economics - Price differentials between ethane and natural gas can cause natural gas processors to recover ethane or leave it in the natural gas stream, known as ethane rejection. As a result of these ethane economics, ethane volumes on our system can fluctuate. Ethane volumes under long-term contracts delivered to our NGL system decreased approximately 30 MBbl/d to an average of 430 MBbl/d in the first quarter 2023, compared with an average of 460 MBbl/d in the first quarter 2022, due primarily to changes in ethane extraction economics. We estimate that there are approximately 250 MBbl/d of discretionary ethane, consisting of approximately 150 MBbl/d in the Rocky Mountain region and approximately 100 MBbl/d in the Mid-Continent region, that could be recovered and transported on our system.
Capital Projects - We operate an integrated, reliable and diversified network of NGL and natural gas gathering, processing, fractionation, transportation and storage assets connecting supply in the Rocky Mountain, Mid-Continent and Permian regions with key market centers. Our primary capital projects are outlined in the table below:

Project | Scope | Approximate Cost (a) | Completion
Natural Gas Gathering and Processing | (In millions) |
Demicks Lake III plant | 200 MMcf/d processing plant in the core of the Williston Basin | $188 | Completed
Natural Gas Liquids |  |  |
MB-5 fractionator | 125 MBbl/d NGL fractionator in Mont Belvieu, Texas | $750 | Completed
MB-6 fractionator | 125 MBbl/d NGL fractionator in Mont Belvieu, Texas | $550 | First Quarter 2025
Natural Gas Pipelines |  |
Viking compression | Upgrade reliability of certain compressor assets | $95 | Third Quarter 2023

(a) - Excludes capitalized interest/AFUDC.
Debt Repayments - In February 2023, we redeemed our $425 million, 5.0% senior notes due September 2023 at 100% of the principal amount, plus accrued and unpaid interest, with cash on hand.
24

Table of Contents
Subsequent eve nt - In April, we elected to redeem our $500 million, 7.5% senior notes due September 2023, with an effective redemption date in June 2023. The redemption price will be 100% of the principal amount of the notes, plus accrued and unpaid interest, which we expect to pay with cash on hand.
Dividends - In February 2023, we paid a quarterly common stock dividend of $0.955 per share ($3.82 per share on an annualized basis), an increase of 2% compared with the same quarter in the prior year. Our dividend growth is primarily due to the increase in cash flows resulting from the growth of our operations. We declared a quarterly common stock dividend of $0.955 per share ($3.82 per share on an annualized basis) in April 2023. The quarterly common stock dividend will be paid May 15, 2023, to shareholders of record at the close of business on May 1, 2023.
FINANCIAL RESULTS AND OPERATING INFORMATION
How We Evaluate Our Operations
Management uses a variety of financial and operating metrics to analyze our performance. Our consolidated financial metrics include: (1) operating income; (2) net income; (3) diluted EPS; and (4) adjusted EBITDA. We evaluate segment operating results using adjusted EBITDA and our operating metrics, which include various volume and rate statistics that are relevant for the respective segment. These operating metrics allow investors to analyze the various components of segment financial results in terms of volumes and rate/price. Management uses these metrics to analyze historical segment financial results and as the key inputs for forecasting and budgeting segment financial results. For additional information on our operating metrics, see the respective segment subsections of this “Financial Results and Operating Information” section.
Non-GAAP Financial Measures - Adjusted EBITDA is a non-GAAP measure of our financial performance. Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes, allowance for equity funds used during construction, noncash compensation expense and certain other noncash items. We believe this non-GAAP financial measure is useful to investors because it and similar measures are used by many companies in our industry as a measurement of financial performance and is commonly employed by financial analysts and others to evaluate our financial performance and to compare financial performance among companies in our industry. Adjusted EBITDA should not be considered an alternative to net income, EPS or any other measure of financial performance presented in accordance with GAAP. Additionally, this calculation may not be comparable with similarly titled measures of other companies.

Changes in commodity prices and sales volumes affect both revenues and cost of sales and fuel in our Consolidated Statements of Income and, therefore, the impact is largely offset between these line items.
Operating income increased $835 million for the three months ended March 31, 2023, compared with the same period in 2022, primarily as a result of the following:
•Natural Gas Liquids - an increase of $733 million related to the Medford incident, due to the settlement gain of $779 million, offset partially by $46 million of third-party fractionation costs, and an increase of $29 million in exchange services due primarily to higher volumes in the Rocky Mountain region and Permian Basin;
•Natural Gas Gathering and Processing - an increase of $49 million due primarily to higher average fee rates and net realized prices, net of hedging and $31 million from higher volumes in the Mid-Continent and Rocky Mountain regions; and
•Natural Gas Pipelines - an increase of $17 million in storage services due primarily to higher storage rates and $5 million in transportation services; offset by
•Consolidated Operating Costs - an increase of $32 million due primarily to higher employee-related costs, outside services and property taxes related primarily to the growth of our operations.
Net income and diluted EPS increased for the three months ended March 31, 2023, compared with the same period in 2022, due primarily to the items discussed above, benefits related to the mark-to-market of investments associated with certain benefit plan investments, increased interest income due to both higher cash balances and higher interest rates and lower interest expense related to increased capitalized interest and lower debt balances.
Capital expenditures increased for the three months ended March 31, 2023, compared with the same period in 2022, due primarily to our growth projects, including the construction of our MB-5 fractionator and Viking compression project.
Additional information regarding our financial results and operating information is provided in the following discussion for each of our segments.
Natural Gas Gathering and Processing
Overview - Our Natural Gas Gathering and Processing segment provides midstream services to producers in North Dakota, Montana, Wyoming, Kansas and Oklahoma. Raw natural gas is typically gathered at the wellhead, compressed and transported through pipelines to our processing facilities. Most raw natural gas produced at the wellhead also contains a mixture of NGL components, including ethane, propane, iso-butane, normal butane and natural gasoline. Processed natural gas, usually referred to as residue natural gas, is then recompressed and delivered to natural gas pipelines, storage facilities and end users. The NGLs separated from the raw natural gas are sold and delivered through NGL pipelines to fractionation facilities for further processing.
Our Natural Gas Gathering and Processing segment’s earnings are primarily fee-based, but we have some direct commodity price exposure related primarily to fee with POP contracts. Under certain fee with POP contracts, our contractual fees and POP percentage may increase or decrease if production volumes, delivery pressures or commodity prices change relative to specified thresholds. To mitigate the impact of this commodity price exposure, we have hedged a significant portion of our Natural Gas Gathering and Processing segment’s commodity price risk for the remainder of 2023 and began hedging into 2024. This segment has substantial long-term acreage dedications in some of the most productive areas of the Williston Basin, which helps to mitigate long-term volumetric risk.
Capital Projects - Our Natural Gas Gathering and Processing segment has invested in growth projects in NGL-rich areas in the Williston Basin. See “Capital Projects” in the “Recent Developments” section for more information on our capital projects.
For a discussion of our capital expenditure financing, see “Capital Expenditures” in the “Liquidity and Capital Resources” section.

Our average fee rate increased due primarily to inflation-based escalators in our contracts, and for certain fee with POP contracts, our contractual fees increased due to production volumes, delivery pressures or commodity prices relative to specified contractual thresholds.
Natural Gas Liquids
Overview - Our Natural Gas Liquids segment owns and operates facilities that gather, fractionate, treat and distribute NGLs and store purity NGLs, primarily in Oklahoma, Kansas, Texas, New Mexico and the Rocky Mountain region, which includes the Williston, Powder River and DJ Basins. We provide midstream services to producers of NGLs and deliver those products to the two primary market centers: one in the Mid-Continent in Conway, Kansas, and the other in the Gulf Coast in Mont Belvieu, Texas. We own or have an ownership interest in FERC-regulated NGL gathering and distribution pipelines in Oklahoma, Kansas, Texas, New Mexico, Montana, North Dakota, Wyoming and Colorado, and terminal and storage facilities in Kansas, Nebraska, Iowa and Illinois. We have a 50% ownership interest in Overland Pass, which operates an interstate NGL pipeline originating in Wyoming and Colorado and terminating in Kansas. The majority of the pipeline-connected natural gas processing plants in the Williston Basin, Oklahoma, Kansas and the Texas Panhandle are connected to our NGL gathering

systems. We lease rail cars and own and operate truck- and rail-loading and -unloading facilities connected to our NGL fractionation, storage and pipeline assets. We also own FERC-regulated NGL distribution pipelines in Kansas, Nebraska, Iowa, Illinois and Indiana that connect our Mid-Continent assets with Midwest markets, including Chicago, Illinois. A portion of our ONEOK North System transports refined petroleum products, including unleaded gasoline and diesel, from Kansas to Iowa.
Capital Projects - Our Natural Gas Liquids segment invests ingrowth projects to transport, fractionate, store and deliver to market centers NGL supply from shale and other resource development areas. Our growth strategy is focused around connecting diversified supply basins from the Rocky Mountain region through the Mid-Continent region and the Permian Basin with demand for purity NGLs from the petrochemical and refining industries and NGL exports in the Gulf Coast. See “Capital Projects” in the “Recent Developments” section for more information on our capital projects.
In the first quarter 2023, we connected one third-party natural gas processing plant in the Permian Basin and one affiliate natural gas processing plant in the Rocky Mountain region.
For a discussion of our capital expenditure financing, see “Capital Expenditures” in the “Liquidity and Capital Resources” section.

Changes in commodity prices and sales volumes affect both revenues and cost of sales and fuel and, therefore, the impact is largely offset between these line items.
Adjusted EBITDA increased $753 million for the three months ended March 31, 2023, compared with the same period in 2022, primarily as a result of the following:
•an increase of $733 million related to the Medford incident, due to the settlement gain of $779 million, offset partially by $46 million of third-party fractionation costs;
•an increase of $29 million in exchange services due primarily to:
◦an increase of $36 million from higher volumes primarily in the Rocky Mountain region and Permian Basin, and
◦an increase of $12 million from higher average fee rates, offset partially by
◦a decrease of $20 million related to narrower commodity price differentials and lower related volumes; and
•an increase of $8 million in optimization and marketing due primarily to higher earnings on sales of purity NGLs held in inventory; offset by
•an increase of $26 million in operating costs due primarily to higher outside service costs, higher employee-related costs and higher property taxes related primarily to the growth of our operations.
Capital expenditures increased for the three months ended March 31, 2023, compared with the same period in 2022, due primarily to growth projects, including our MB-5 fractionator.

We generally expect ethane volumes to increase or decrease with corresponding increases or decreases in overall NGL production. However, ethane volumes may experience growth or decline greater than corresponding growth or decline in overall NGL production due to ethane economics causing producers to recover or reject ethane.
Volumes increased for the three months ended March 31, 2023, compared with the same period in 2022, due primarily to increased production in the Permian Basin and Rocky Mountain region, offset partially by lower ethane volumes in the Mid-Continent and Rocky Mountain regions.
Natural Gas Pipelines
Overview - In our Natural Gas Pipelines segment, our assets are connected to key supply areas and demand centers, including export markets in Mexico via Roadrunner and supply areas in Canada and the United States via our interstate and intrastate natural gas pipelines and Northern Border, which enable us to provide essential natural gas transportation and storage services. Continued demand from local distribution companies, electric-generation facilities and large industrial companies supported low-cost expansions that position us well to provide additional services to our customers when needed.
Capital Projects - Our Natural Gas Pipelines segment invests in growth projects that provide transportation and storage services to end users. In December 2022, our Saguaro Connector Pipeline L.L.C. subsidiary filed a Presidential Permit application with the FERC to construct and operate new international border-crossing facilities at the U.S. and Mexico border. The proposed border facilities would connect upstream with a potential intrastate pipeline, the Saguaro Connector Pipeline, which would be owned and operated by ONEOK. Additionally, the proposed border facilities would connect at the international boundary with a new pipeline under development in Mexico for delivery to a liquefied natural gas export facility on the west coast of Mexico. The final investment decision on the pipeline is expected by mid-2023.
See “Capital Projects” in the “Recent Developments” section for more information on our capital projects.

Table of Contents
Adjusted EBITDA increased $21 million for the three months ended March 31, 2023, compared with the same period in 2022, primarily as a result of the following:
•an increase of $17 million in storage services due primarily to higher storage rates on renegotiated contracts; and
•an increase of $5 million in transportation services due primarily to higher firm and interruptible volumes; offset by
•an increase of $4 million in operating costs due primarily to higher employee-related costs.
Capital expenditur e s increased for the three months ended March 31, 2023, compared with the same period in 2022, due primarily to growth projects, including the Viking compression project.

In April 2022, the FERC initiated a review of Guardian’s rates pursuant to Section 5 of the Natural Gas Act. In August 2022, Guardian reached a settlement in principle with the participants in the Section 5 rate case. The FERC approved the settlement in February 2023, which resulted in a reduction of rates starting in April 2023. We do not expect the reduced rates to have a material impact on our results of operations.

CONTINGENCIES
See Note J of the Notes to Consolidated Financial Statements in this Quarterly Report for discussion of regulatory and environmental matters.
LIQUIDITY AND CAPITAL RESOURCES
General - Our primary sources of cash inflows are operating cash flows, proceeds from our commercial paper program and our $2.5 Billion Credit Agreement, debt issuances and the issuance of common stock for our liquidity and capital resources requirements.
30

Table of Contents
On January 9, 2023, we reached an agreement with our insurers to settle all claims for physical damage and business interruption related to the Medford incident. Under the terms of the settlement agreement, we agreed to resolve the claims for total insurance payments of $930 million, $100 million of which was received in 2022. The remaining $830 million was received in the first quarter 2023. The proceeds serve as settlement for property damage, business interruption claims to the date of settlement and as payment in lieu of future business interruption insurance claims. We expect our cash from operations in the remainder of 2023 and in 2024 to be impacted by incurred costs resulting from the Medford incident for which we will no longer receive business interruption proceeds.
We expect our sources of cash inflows to provide sufficient resources to finance our operations, quarterly cash dividends, capital expenditures, maturities of long-term debt and contributions to unconsolidated affiliates. We believe we have sufficient liquidity due to our $2.5 Billion Credit Agreement, which expires in June 2027, and access to $1 billion available through our “at-the-market” equity program. As of the date of this report, no shares have been sold through our “at-the-market” equity program.
We may manage interest-rate risk through the use of fixed-rate debt, floating-rate debt and interest-rate swaps. For additional information on our interest-rate swaps, see Note D of the Notes to Consolidated Financial Statements in this Quarterly Report.
Cash Management - At March 31, 2023, we had $680 million of cash and cash equivalents. Our cash balance is composed primarily of highly liquid government and treasury money market funds and deposits fully insured by the Federal Deposit Insurance Corporation.
We use a centralized cash management program that concentrates the cash assets of our nonguarantor operating subsidiaries in joint accounts for the purposes of providing financial flexibility and lowering the cost of borrowing, transaction costs and bank fees. Our centralized cash management program provides that funds in excess of the daily needs of our operating subsidiaries are concentrated, consolidated or otherwise made available for use by other entities within our consolidated group. Our operating subsidiaries participate in this program to the extent they are permitted pursuant to FERC regulations or their operating agreements. Under the cash management program, depending on whether a participating subsidiary has short-term cash surpluses or cash requirements, we provide cash to the subsidiary or the subsidiary provides cash to us.
Guarantees - We and ONEOK Partners are issuers of certain public debt securities. We guarantee certain indebtedness of ONEOK Partners, and ONEOK Partners and the Intermediate Partnership guarantee certain of our indebtedness. As allowed under Rule 13-01, we have excluded the summarized financial information for each issuer and guarantor as the combined financial information of the subsidiary issuer and parent guarantor, excluding our ownership of all the interests in ONEOK Partners, reflect no material assets, liabilities or results of operations, apart from the guaranteed indebtedness. For additional information on our and ONEOK Partners indebtedness, please see Note E of the Notes to Consolidated Financial Statements in this Quarterly Report.
Short-term Liquidity - Our principal sources of short-term liquidity consist of cash generated from operating activities, distributions received from our equity-method investments, proceeds from our commercial paper program and our $2.5 Billion Credit Agreement. As of March 31, 2023, we had no borrowings under our $2.5 Billion Credit Agreement and we are in compliance with all covenants.
As of March 31, 2023, we had a working capital surplus of $387 million (defined as current assets less current liabilities). Although working capital is influenced by several factors, including, among other things: (i) the timing of (a) debt and equity issuances, (b) the funding of capital expenditures, (c) scheduled debt payments, and (d) accounts receivable and payable; and (ii) the volume and cost of inventory and commodity imbalances, our working capital surplus at March 31, 2023, was driven primarily by insurance proceeds received from the Medford settlement. We may have working capital deficits in future periods as we continue to repay long-term debt. We do not expect a working capital deficit of this nature to have an adverse impact to our cash flows or operations.
For additional information on our $2.5 Billion Credit Agreement, see Note E of the Notes to Consolidated Financial Statements in this Quarterly Report.
Long-term Financing - In addition to our principal sources of short-term liquidity discussed above, we expect to fund our longer-term financing requirements by issuing long-term notes, as needed. Other options to obtain financing include, but are not limited to, issuing common stock, loans from financial institutions, issuance of convertible debt securities or preferred equity securities, asset securitization and the sale and lease-back of facilities.
31

Table of Contents
Viking Term Loan Agreement - In March 2023, Viking entered into a $60 million senior unsecured Term Loan Agreement, and drew $50 million available under the agreement. Viking used the proceeds primarily to repay intercompany debt with ONEOK.
Debt Repayments - In February 2023, we redeemed our $425 million, 5.0% senior notes due September 2023 at 100% of the principal amount, plus accrued and unpaid interest, with cash on hand.
Subsequent event - In April, we elected to redeem our $500 million, 7.5% senior notes due September 2023, with an effective redemption date in June 2023. The redemption price will be 100% of the principal amount of the notes, plus accrued and unpaid interest, which we expect to pay with cash on hand.
For additional information on our long-term debt, see Note E of the Notes to Consolidated Financial Statements in this Quarterly Report.
Capital Expenditures - We classify expenditures that are expected to generate additional revenue, return on investment or significant operating or environmental efficiencies as growth capital expenditures. Maintenance capital expenditures are those capital expenditures required to maintain our existing assets and operations and do not generate additional revenues. Maintenance capital expenditures are made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives. Our capital expenditures are financed typically through operating cash flows and short- and long-term debt.
Capital expenditures, excluding AFUDC, were $289 million and $257 million for the three months ended March 31, 2023 and 2022, respectively.
We expect total capital expenditures, excluding AFUDC and capitalized interest, of $1.3-$1.5 billion in 2023.
Credit Ratings - Our long-term debt credit ratings as of April 24, 2023, are shown in the table below:

Rating Agency | Long-Term Rating | Short-Term Rating | Outlook
Moody’s | Baa2 | Prime-2 | Stable
S&P | BBB | A-2 | Stable
Fitch | BBB | F2 | Stable

Our credit ratings, which are investment grade, may be affected by our leverage, liquidity, credit profile or potential transactions. In April 2023, Moody’s upgraded our long-term rating to Baa2 from Baa3, our short-term rating to Prime-2 from Prime-3 and changed the outlook to stable from positive. The most common criteria for assessment of our credit ratings are the debt-to-EBITDA ratio, interest coverage, business risk profile and liquidity. If our credit ratings were downgraded, our cost to borrow funds under our $2.5 Billion Credit Agreement could increase and a potential loss of access to the commercial paper market could occur. In the event that we are unable to borrow funds under our commercial paper program and there has not been a material adverse change in our business, we would continue to have access to our $2.5 Billion Credit Agreement, which expires in 2027. An adverse credit rating change alone is not a default under our $2.5 Billion Credit Agreement.
In the normal course of business, our counterparties provide us with secured and unsecured credit. In the event of a downgrade in our credit ratings or a significant change in our counterparties’ evaluation of our creditworthiness, we could be required to provide additional collateral in the form of cash, letters of credit or other negotiable instruments as a condition of continuing to conduct business with such counterparties. We may be required to fund margin requirements with our counterparties with cash, letters of credit or other negotiable instruments.
Dividends - Holders of our common stock share equally in any common stock dividends declared by our Board of Directors, subject to the rights of the holders of outstanding preferred stock. In February 2023, we paid a common stock dividend of $0.955 per share ($3.82 per share on an annualized basis), an increase of 2% compared with the same quarter in the prior year. A common stock dividend of $0.955 per share was declared for the shareholders of record at the close of business on May 1, 2023, payable May 15, 2023.
Our Series E Preferred Stock pays quarterly dividends on each share of Series E Preferred Stock, when, as and if declared by our Board of Directors, at a rate of 5.5% per year. We paid dividends for the Series E Preferred Stock of $0.3 million in February 2023. Dividends totaling $0.3 million were declared for the Series E Preferred Stock and are payable May 15, 2023.

Table of Contents
For the three months ended March 31, 2023, our cash flows from operations exceeded dividends paid by $794 million. We expect our cash flows from operations to continue to sufficiently fund our cash dividends. To the extent operating cash flows are not sufficient to fund our dividends, we may utilize cash on hand from other sources of short- and long-term liquidity to fund a portion of our dividends.
CASH FLOW ANALYSIS
We use the indirect method to prepare our Consolidated Statements of Cash Flows. Under this method, we reconcile net income to cash flows provided by operating activities by adjusting net income for those items that affect net income but do not result in actual cash receipts or payments during the period and for operating cash items that do not impact net income. These reconciling items can include depreciation and amortization, deferred income taxes, impairment charges, allowance for equity funds used during construction, gain or loss on sale of assets, net undistributed earnings from equity-method investments, share-based compensation expense, other amounts and changes in our assets and liabilities not classified as investing or financing activities.
The following table sets forth the changes in cash flows by operating, investing and financing activities for the periods indicated:

|  |  | Variances
| Three Months Ended |  | 2023 vs. 2022
| March 31, |  | Favorable (Unfavorable)
| 2023 |  | 2022 |
| (Millions of dollars)
Total cash provided by (used in): |  |  |  |  |
Operating activities | $ | 1,221 |  |  | $ | 463 |  |  | $ | 758 |
Investing activities | 47 |  |  | (244) |  |  | 291 |
Financing activities | (808) |  |  | (350) |  |  | (458) |
Change in cash and cash equivalents | 460 |  |  | (131) |  |  | 591 |
Cash and cash equivalents at beginning of period | 220 |  |  | 146 |  |  | 74 |
Cash and cash equivalents at end of period | $ | 680 |  |  | $ | 15 |  |  | $ | 665 |

Operating Cash Flows - Operating cash flows are affected by earnings from our business activities and changes in our operating assets and liabilities. Changes in commodity prices and demand for our services or products, whether because of general economic conditions, changes in supply, changes in demand for the end products that are made with our products or increased competition from other service providers, could affect our earnings and operating cash flows. Our operating cash flows can also be impacted by changes in our NGLs and natural gas inventory balances, which are driven primarily by commodity prices, supply, demand and the operation of our assets.
Cash flows from operating activities, before changes in operating assets and liabilities for the three months ended March 31, 2023, increased $559 million compared with t he same period in 2022, due primarily to insurance proceeds received from the Medford settlement, and higher net income resulting from higher exchange services in our Natural Gas Liquids segment, higher average fees rates and net realized prices, net of hedging, in our Natural Gas Gathering and Processing segment and higher storage services in our Natural Gas Pipelines segment, as discussed in “Financial Results and Operating Information.”
The changes in operating assets and liabilities decreased operating cash flows $19 million for the three months ended March 31, 2023, compared with a decrease of $218 million for the s ame period in 2022. This change is due primarily to changes in accounts receivable resulting from the timing of receipt of cash from customers and NGLs and natural gas in inventory, both of which vary from period to period and with changes in commodity prices, and changes in risk management assets and liabilities; offset partially by changes in accounts payable, which also vary from period to period with changes in commodity prices, and from the timing of payments to vendors, suppliers and other third parties.
Investing Cash Flows - Cash from investing activities for the three months ended March 31, 2023, increased $291 million, compared with the same period in 2022, due primarily to insurance proceeds received from the Medford settlement.
Financing Cash Flows - Cash used in financing activities for the three months ended March 31, 2023, increased $458 million, compared with the same period in 2022, due primarily to the repayment of long-term debt.

IMPACT OF NEW ACCOUNTING STANDARDS
See Note A of the Notes to Consolidated Financial Statements in this Quarterly Report for discussion of new accounting standards.
CRITICAL ACCOUNTING ESTIMATES
The preparation of our Consolidated Financial Statements and related disclosures in accordance with GAAP requires us to make estimates and assumptions with respect to values or conditions that cannot be known with certainty that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements. These estimates and assumptions also affect the reported amounts of revenue and expenses during the reporting period. Although we believe these estimates and assumptions are reasonable, actual results could differ from our estimates.
Information about our critical accounting estimates is included under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, “Critical Accounting Policies and Estimates,” in our Annual Report.
FORWARD-LOOKING STATEMENTS
Some of the statements contained and incorporated in this Quarterly Report are forward-looking statements as defined under federal securities laws. The forward-looking statements relate to our anticipated financial performance (including projected operating income, net income, capital expenditures, cash flows and projected levels of dividends), liquidity, management’s plans and objectives for our future capital projects and other future operations (including plans to construct additional natural gas and NGL pipelines, processing and fractionation facilities and related cost estimates), our business prospects, the outcome of regulatory and legal proceedings, market conditions and other matters. We make these forward-looking statements in reliance on the safe harbor protections provided under federal securities legislation and other applicable laws. The following discussion is intended to identify important factors that could cause future outcomes to differ materially from those set forth in the forward-looking statements.
Forward-looking statements and other statements in this Quarterly Report regarding our environmental, social and other sustainability targets, plans and goals are not an indication that these statements are required to be disclosed in our filings with the SEC, or that we will continue to make similar statements in the same extent or manner in future filings. In addition, historical, current and forward-looking environmental, social and sustainability-related statements may be based on standards and processes for measuring progress that are still developing and that continue to evolve, and assumptions that are subject to change in the future.
Forward-looking statements include the items identified in the preceding paragraph, the information concerning possible or assumed future results of our operations and other statements contained or incorporated in this Quarterly Report identified by words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “intend,” “may,” “might,” “outlook,” “plan,” “potential,” “project,” “scheduled,” “should,” “target,” “will,” “would,” and other words and terms of similar meaning.
One should not place undue reliance on forward-looking statements. Known and unknown risks, uncertainties and other factors may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by forward-looking statements. Those factors may affect our operations, markets, products, services and prices. In addition to any assumptions and other factors referred to specifically in connection with the forward-looking statements, factors that could cause our actual results to differ materially from those contemplated in any forward-looking statement include, among others, the following:
•the impact of inflationary pressures, including increased interest rates, which may increase our capital expenditures and operating costs, raise the cost of capital or depress economic growth;
