2021 Activity—On March 3, 2021, the Company completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for an additional $300 aggregate principal amount of 6.125% Senior Secured Second-Lien Notes due 2028 (the “Additional 2028 Notes”). The Additional 2028 Notes were issued under the indenture governing Arconic’s existing 6.125% Senior Secured Second-Lien Notes due 2028 (see 2020 Activity below). Other than with respect to the date of issuance and issue price, the Additional 2028 Notes are treated as a single series with and have the same terms as the referenced existing notes. The Additional 2028 Notes were sold at 106.25% of par (i.e., a premium) and, after reflecting a discount to the initial purchasers of the Additional 2028 Notes, the Company received $315 in net proceeds from the debt offering. Arconic used the net proceeds of this issuance to fund an annuitization of certain U.S. defined benefit pension plan obligations (see Note H). The premium ($19) and costs to complete the financing ($5) were deferred and are being amortized to interest expense over the term of the Additional 2028 Notes. The amortization of the premium is reflected as a reduction to interest expense and the amortization of the costs to complete the financing is reflected as an addition to interest expense. Interest on the Additional 2028 Notes is paid semi-annually in February and August and commenced August 15, 2021.

2020 Activity—In connection with the capital structure to be established at the time of the Separation, Arconic secured $1,200 in third-party indebtedness. On February 7, 2020, Arconic completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $600 of 6.125% Senior Secured Second-Lien Notes due 2028 (the “2028 Notes”). The Company received $593 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2028 Notes. Also, on March 25, 2020, Arconic entered into a credit agreement, which provided a $600 Senior Secured First-Lien Term Loan B Facility (variable rate and seven-year term) (the “Term Loan”) and a $1,000 Senior Secured First-Lien Revolving Credit Facility (variable rate and five-year term) (the “Credit Facility”), with a syndicate of lenders and issuers named therein (the “Credit Agreement”). The Company received $575 in net proceeds from the Term Loan reflecting upfront fees and costs to enter into the financing arrangement.

The Company used a portion of the $1,168 in net proceeds from the aggregate indebtedness to make a $728 payment to ParentCo on April 1, 2020 to fund the transfer of certain net assets from ParentCo to Arconic in connection with the completion of the Separation (see Note A). The payment to ParentCo was calculated as the difference between (i) the $1,168 of net proceeds from the aggregate indebtedness and (ii) the difference between a beginning cash balance at the Separation Date of $500, as provided for in the Separation and Distribution Agreement, and the amount of cash held by Arconic Businesses at March 31, 2020 ($60 – the sum of this amount and the aggregate indebtedness in (i) equals the sum of Cash and cash equivalents and Restricted cash on the Company’s Combined Balance Sheet as of March 31, 2020).

On May 13, 2020, Arconic executed a refinancing of its existing Credit Agreement in order to provide improved financial flexibility. Arconic completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $700 of 6.0% Senior Secured First-Lien Notes due 2025 (the “2025 Notes”). The Company received $691 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2025 Notes. Additionally, Arconic entered into a credit agreement with a syndicate of lenders named therein and Deutsche Bank AG New York Branch, as administrative agent (the “ABL Credit Agreement”). The ABL Credit Agreement provides for a senior secured asset-based revolving credit facility in an aggregate principal amount of $800 (see Note V), including a letter of credit sub-facility and a swingline loan sub-facility (the “ABL Credit Facility”). In addition, the ABL Credit Facility includes an accordion feature allowing the Company to request one or more increases to the revolving commitments in an aggregate principal amount up to $350 (see Note V).

In connection with the issuance of the 2028 Notes and the execution of the Credit Agreement, the Company paid $42 in discounts to the initial purchasers and/or upfront fees and costs (the “debt issuance costs”), of which $30 was attributable to the Term Loan and the Credit Facility. The debt issuance costs were initially deferred and were being amortized to interest expense over the respective terms of the 2028 Notes, the Term Loan, and the Credit Facility. In connection with the issuance of the 2025 Notes and the execution of the ABL Credit Agreement, the Company paid $15 in discounts to the initial purchasers and/or upfront fees and costs (the “new debt issuance costs”). As a result of applying both debt modification and debt extinguishment accounting, as appropriate based on the lender mix for each debt instrument, to the debt refinancing, the Company was required to write off $16 of the $30 in debt issuance costs and immediately expense $3 of the $15 in new debt issuance costs. This $19 was reported within Interest expense on the Company’s Statement of Consolidated Operations. The remaining $14 in debt issuance costs continued to be deferred and the remaining $12 in new debt issuance costs were deferred; both are being amortized to interest expense over the respective terms of the 2025 Notes and the ABL Credit Agreement.

Separately, in August 2012, ParentCo and the Iowa Finance Authority entered into a loan agreement for the proceeds from the issuance of $250 in Midwestern Disaster Area Revenue Bonds Series 2012 due 2042 (the “Bonds”). The Bonds were issued by the Iowa Finance Authority pursuant to the Heartland Disaster Tax Relief Act of 2008 for the purpose of financing all or part of the cost of acquiring, constructing, reconstructing, and renovating certain facilities (the “Project”) at Arconic’s rolling mill plant in Davenport, IA. The loan proceeds could only be used for this purpose and, therefore, were included on the Company’s Combined Balance Sheet for all periods prior to the Separation Date. In accordance with the Separation and Distribution Agreement, as well as a Second Supplemental Tax and Project Certificate and Agreement, dated March 31, 2020, to the Tax Exemption Certificate and Agreement, dated August 14, 2012, (collectively, the “Tax Agreement”), ParentCo remained the borrower associated with the Bonds and Arconic is the legal owner of the Davenport facility, including the Project. The Company has no financial obligations related to the future debt service of the Bonds but is required to continue to operate, and maintain the location of, the Project in accordance with the Tax Agreement. Accordingly, the $250 carrying value of the Bonds, as well as related accrued interest, was removed from Arconic’s Consolidated Balance Sheet in connection with the Separation.

Arconic has the option to redeem the 2028 Notes on at least 10 days, but not more than 60 days, prior notice to the holders of the 2028 Notes under multiple scenarios, including, in whole or in part, at any time or from time to time after February 14, 2023 at a redemption price specified in the indenture (up to 103.063% of the principal amount plus any accrued and unpaid interest in each case). At any time prior to February 15, 2023, the Company may redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed plus a “make-whole” redemption price

determined as the greater of (1) 1.0% of the principal amount of such notes and (2) the excess, if any, of (a) the present value at the date of redemption of (i) 103.063% of the principal amount of such notes plus (ii) all required interest payments due on such notes (excluding accrued but unpaid interest to the date of redemption) through February 15, 2023, computed using a discount rate equal to, generally, the yield to maturity of United States Treasury securities with a constant maturity as of the date of redemption plus 50 basis points, over (b) the principal amount of such notes, as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption. Also, at any time prior to February 15, 2023, Arconic may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the notes at a redemption price equal to 106.125% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, with the net cash proceeds of certain equity offerings, if at least 60% of the original aggregate principal amount of the notes remains outstanding immediately after such redemption and the redemption occurs within 120 days of the date of such equity offering. Additionally, the 2028 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2028 Notes repurchased, plus any accrued and unpaid interest on the 2028 Notes repurchased.

The 2028 Notes are senior secured obligations of Arconic and do not entitle the holders to any registration rights pursuant to a registration rights agreement. The Company does not intend to file a registration statement with respect to resales of or an exchange offer for the 2028 Notes. The 2028 Notes are guaranteed on a senior secured basis by Arconic and its subsidiaries that are guarantors (the “subsidiary guarantors” and, together with Arconic, the “guarantors”) under the ABL Credit Agreement (see below). Each of the subsidiary guarantors will be released from their 2028 Notes guarantees upon the occurrence of certain events, including the release of such guarantor from its obligations as a guarantor under the ABL Credit Agreement.

The 2028 Notes indenture includes several customary affirmative covenants. Additionally, the 2028 Notes indenture contains several negative covenants, that, subject to certain exceptions, limit the Company’s ability to, among other things, (i) make investments, loans, advances, guarantees, and acquisitions, (ii) pay dividends on or make other distributions in respect of capital stock and make other restricted payments and investments (as defined in the 2028 Notes), (iii) sell or transfer certain assets, and (iv) create liens on assets to secure debt.

The 2028 Notes rank equally in right of payment with all of Arconic’s existing and future senior indebtedness, including the facility under the ABL Credit Agreement (see below); rank senior in right of payment to any future subordinated obligations of Arconic; and are effectively subordinated to Arconic’s existing and future secured indebtedness that is secured on a first priority basis, including the 2025 Notes and the facility under the ABL Credit Agreement, to the extent of the value of property and assets securing such indebtedness.

Arconic has the option to redeem the 2025 Notes on at least 10 days, but not more than 60 days, prior notice to the holders of the 2025 Notes under multiple scenarios, including, in whole or in part, at any time or from time to time after May 14, 2022 at a redemption price specified in the indenture (up to 103.0% of the principal amount plus any accrued and unpaid interest in each case). At any time prior to May 15, 2022, the Company may redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed plus a “make-whole” redemption price determined as the greater of (1) 1.0% of the principal amount of such notes and (2) the excess, if any, of (a) the present value at the date of redemption of (i) 103.0% of the principal amount of such notes plus (ii) all required interest payments due on such notes (excluding accrued but unpaid interest to the date of redemption) through May 15, 2022, computed using a discount rate equal to, generally, the yield to maturity of United States Treasury securities with a constant maturity as of the date of redemption plus 50 basis points, over (b) the principal amount of such notes, as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption. Also, at any time prior to May 15, 2022, Arconic may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the notes at a redemption price equal to 106.0% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, with the net cash proceeds of certain equity offerings, if at least 60% of the original aggregate principal amount of the notes remains outstanding immediately after such redemption and the redemption occurs within 120 days of the date of such equity offering. Additionally, the 2025 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2025 Notes repurchased, plus any accrued and unpaid interest on the 2025 Notes repurchased.

The 2025 Notes are senior secured obligations of Arconic and do not entitle the holders to any registration rights pursuant to a registration rights agreement. The Company does not intend to file a registration statement with respect to resales of or an exchange offer for the 2025 Notes. The 2025 Notes are guaranteed on a senior secured basis by Arconic and its subsidiaries that are guarantors (the “subsidiary guarantors” and, together with Arconic, the “guarantors”) under the ABL Credit Agreement (see below). Each of the subsidiary guarantors will be released from their 2025 Notes guarantees upon the occurrence of certain events, including the release of such guarantor from its obligations as a guarantor under the ABL Credit Agreement.

The 2025 Notes indenture includes several customary affirmative covenants. Additionally, the 2025 Notes indenture contains several negative covenants, that, subject to certain exceptions, limit the Company’s ability to, among other things, (i) pay dividends on or make other distributions in respect of capital stock and make other restricted payments and investments (as defined in the 2025 Notes), (ii) sell or transfer certain assets, (iii) incur indebtedness, and (iv) create liens on assets to secure debt.

The 2025 Notes are secured on a first priority basis by certain defined collateral (generally consisting of the Company’s and the Guarantors’ equipment, material owned U.S. real property, intellectual property, certain stock, and other tangible and intangible personal property, in each case, subject to certain exceptions) and on a second priority basis by certain other assets (generally consisting of substantially all of the accounts receivable, inventory, deposit accounts, securities accounts, commodities accounts, and cash assets of the Company and the Guarantors, and the proceeds thereof).

The ABL Credit Facility is scheduled to mature on May 13, 2025, unless extended or earlier terminated in accordance with the ABL Credit Agreement. Under the provision of the ABL Credit Agreement, Arconic will pay a quarterly commitment fee ranging from 0.250% to 0.375% (based on Arconic’s leverage ratio) per annum on the unused portion of the ABL Credit Facility, which will be determined based on the Company’s average daily utilization. The ABL Credit Facility was undrawn as of both December 31, 2021 and 2020 and no amounts were borrowed since inception.

The ABL Credit Facility is subject to an interest rate for U.S. dollar borrowings equal to an applicable margin plus, at the Company’s option, of either (a) base rate (“ABR”) determined by reference to the highest of (1) Deutsche Bank AG New York Branch’s “prime rate,” (2) the greater of the federal funds effective rate and the overnight bank funding rate, plus 0.5%, and (3) the one month adjusted LIBO Rate, plus 1% per annum or (b) an adjusted LIBO Rate (which will not be less than 0.75% per annum) (“LIBOR”). The applicable margin for the ABL Credit Facility through June 30, 2021 was (a) 1.25% for ABR loans and (b) 2.25% for LIBOR loans. Thereafter, the applicable margin for the ABL Credit Facility is (a) 0.75% to 1.25% per annum for ABR loans and (b) 1.75% per annum to 2.25% per annum for LIBOR loans based on the average daily excess availability (as defined under the ABL Credit Agreement). Accordingly, the interest rates for the ABL Credit Facility will fluctuate based on changes in the ABR, LIBOR, and/or future changes in the average daily excess availability.

All obligations under the ABL Credit Facility are unconditionally guaranteed, jointly and severally, by substantially all of the direct and indirect wholly-owned material subsidiaries of the Company that are organized under the laws of the United States, any state thereof or the District of Columbia, subject to certain exceptions (collectively, the “Guarantors”). The Company and the Guarantors entered into a guarantee under the ABL Credit Agreement concurrently with the effectiveness of the ABL Credit Agreement.

Subject to certain limitations, the ABL Credit Facility is secured on a first priority basis by certain defined collateral (generally consisting of substantially all of the accounts receivable, inventory, deposit accounts, securities accounts, commodities accounts, and cash assets of the Company and the Guarantors, and the proceeds thereof) and on a second-priority basis by certain defined collateral under the 2025 Notes (generally consisting of the Company and the Guarantors’ equipment, material owned U.S. real property, intellectual property, certain stock, and other tangible and intangible personal property, in each case, subject to exceptions as defined in the 2025 Notes). The Company and the Guarantors entered into collateral agreements concurrently with the effectiveness of the ABL Credit Agreement.

The ABL Credit Facility contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit the Company’s and its subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, to enter into restrictive agreements, to make certain investments, loans, advances, guarantees and acquisitions, to prepay certain indebtedness and to pay dividends, to make other distributions or redemptions/repurchases, in respect of the Company’s and its subsidiaries’ equity interests, to engage in transactions with affiliates and to amend certain material documents.

In addition, the ABL Credit Facility contains a financial maintenance covenant applicable to any fiscal quarter in which the excess availability is less than the greater of (a) 10% of the lesser of (x) the aggregate amount of the commitments under the ABL Credit Facility and (y) the borrowing base and (b) $50. In such circumstances, until such time as excess availability shall have exceeded such threshold for at least 30 consecutive days, the Company would be required to maintain a fixed charge coverage ratio of not less than 1.00 to 1.00. The ABL Credit Facility also requires the Company and its subsidiaries to maintain substantially all of the Company’s cash in accounts that are subject to the control of the agent, which control becomes applicable when (a) an event of default under the facility occurs and is continuing until the first day thereafter on which no event of default shall exist or (b) excess availability is less than the greater of (i) 12.5% of the lesser of (x) the aggregate amount
