PITTSBURGH--(BUSINESS WIRE)--November 1, 2022--Arconic Corporation (NYSE: ARNC) (“Arconic” or “the Company”) today reported third quarter 2022 results. Revenue was $2.3 billion, down 11% from the prior quarter, primarily due to sequential declines in metal prices and lower sales volumes due to production outages and other operational challenges. The Company reported a net loss of $65 million, or $0.64 per share, compared with net income of $16 million, or $0.15 per share in third quarter 2021. Third quarter 2022 includes an after-tax, non-cash asset impairment charge of $70 million related to the Extrusions segment business review.

Third quarter 2022 Adjusted EBITDA was $143 million, a decline of 16% year over year, driven by weakness in industrial production related to operational challenges in the quarter and lower profitability in Europe driven by hyperinflationary energy prices impacting demand and costs. Cash provided from operations was $91 million and capital expenditures were $47 million in the third quarter 2022.

Tim Myers, Chief Executive Officer, said, “The production outages and other operational challenges at the Tennessee and Davenport facilities that impacted third quarter results have been resolved and the affected facilities are now producing at expected rates. Maintenance scheduled for the end of the third quarter was completed successfully and the repaired equipment has been operating consistently for several weeks. While there has been weakness in Europe, demand in North America remains strong. Also in the quarter, we completed our $300 million share repurchase authorization.”

Outlook

The Company is updating its full-year 2022 outlook. Arconic revenue expectations are now in the range of $9.0 billion to $9.3 billion for full-year 2022 compared with the prior expected range of $9.2 billion to $9.5 billion. This assumes LME aluminum price of $2,300/mt and Midwest Premium of $550/mt. Adjusted EBITDA is expected to be in the range of $700 million to $730 million compared to the previously guided range of $715 million to $765 million. The reduction was primarily caused by issues on the Lancaster hot mill, which returned to service from a scheduled outage in late-September. During the outage, a piece of equipment was upgraded to increase capacity, but it is running well below pre-outage rates since returning to production. The production rates from the hot mill have improved throughout October and are expected to return to normal rates by the end of the fourth quarter 2022. Free cash flow for full-year 2022 is now anticipated to be approximately $150 million compared to the prior expectation of approximately $200 million due to reduced profitability and increased working capital.

Share Repurchase Program

In the 2022 third quarter, the Company repurchased approximately 3.0 million shares for a total of approximately $86 million, completing the $300 million authorization.

Arconic will hold its quarterly conference call at 10:00 AM Eastern Time on November 1, 2022, to present third quarter 2022 financial results. The call will be webcast on the Arconic website. Call information and related details are available at www.arconic.com under “Investors.”

Non-GAAP Financial Measures

Some of the information included in this release is derived from Arconic’s consolidated financial information but is not presented in Arconic’s financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Certain of these financial measures are considered “non-GAAP financial measures” under SEC rules. These non-GAAP financial measures supplement our GAAP disclosures and should not be considered an alternative to any measure of performance or financial condition as determined in accordance with GAAP, and investors should consider Arconic’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of Arconic. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP. Non-GAAP financial measures presented by Arconic may not be comparable to non-GAAP financial measures presented by other companies. Reconciliations to the most directly comparable GAAP financial measures and management’s rationale for the use of the non-GAAP financial measures can be found in the schedules to this release. Arconic has not provided reconciliations of any forward-looking non-GAAP financial measures, such as adjusted EBITDA, and free cash flow, to the most directly comparable GAAP financial measures because such reconciliations are not available without unreasonable efforts due to the variability and complexity with respect to the charges and other components excluded from the non-GAAP measures, such as the effects of metal price lag, foreign currency movements, unrealized gains or losses on mark-to-market hedging, gains or losses on sales of assets, taxes, and any future restructuring or impairment charges. These reconciling items are in addition to the inherent variability already included in the GAAP measures, which includes, but is not limited to, price/mix and volume. Arconic believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors.

(1) |  | On May 14, 2022, the Company and the United Steelworkers reached a tentative four-year labor agreement covering approximately 3,300 employees at four U.S. locations; the previous labor agreement expired on May 15, 2022. The tentative agreement was ratified by the union employees on June 1, 2022. In the quarter ended June 30, 2022, Arconic recognized $19 in Cost of goods sold primarily for a one-time signing bonus for the covered employees.
(2) |  | In the quarter ended September 30, 2022, the Company updated its five-year strategic plan, the results of which indicated that there was a decline in the forecasted financial performance for the Extrusions segment (and asset group). As such, management evaluated the recoverability of the long-lived assets of the Extrusions asset group and, ultimately, determined that such assets were impaired. Accordingly, in the quarter ended September 30, 2022, the Company recorded an impairment charge of $92, composed of $90 for Properties, plants, and equipment and $2 for intangible assets.
|  | In the quarters ended September 30, 2022 and 2021, Restructuring and other charges includes $15 and $5, respectively, related to the settlement of a portion of the Company’s U.S. defined benefit pension plan obligations as a result of elections by certain plan participants to receive lump-sum benefit payments.
(3) |  | In the quarters ended September 30, 2022 and June 30, 2022, Other expenses (income), net includes an $11 loss and a $54 gain, respectively, for the remeasurement of monetary balances, primarily cash, related to the Company’s operations in Russia from rubles to the U.S. dollar. This loss and gain were the result of a significant weakening and strengthening, respectively, of the ruble against the U.S. dollar in the respective periods.
(4) |  | For periods in which the Company generates net income, the diluted weighted-average number of shares include common share equivalents associated with outstanding employee stock awards. For periods in which the Company generates a net loss, the diluted weighted-average number of shares does not include any common share equivalents as their effect is anti-dilutive.

(2) |  | In January 2022, the Company entered into a one-year arrangement with a financial institution to sell certain customer receivables outright without recourse on a continuous basis. All such sales are at Arconic's discretion. Under this arrangement, the Company serves in an administrative capacity, including collection of the receivables from the respective customers and remittance of these cash collections to the financial institution. Accordingly, upon the sale of customer receivables to the financial institution, Arconic removes the underlying trade receivables from the Consolidated Balance Sheet and includes the reduction as a positive amount in the Decrease (Increase) in receivables line item within Operating Activities on the Statement of Consolidated Cash Flows. In the quarters ended September 30, 2022 and June 30, 2022, the Company sold customer receivables of $413 and $329, respectively, and remitted cash collections of $380 and $267, respectively, to the financial institution.

In the quarters ended September 30, 2022, June 30, 2022, and September 30, 2021, the Company repurchased 3,033,663, 1,324,027, and 2,862,694, respectively, shares of its common stock under this program. Cumulatively, the Company has repurchased 9,776,177 shares of its common stock for $300 since the program’s inception.
(5) |  | Cash and cash equivalents and restricted cash at beginning of period for all periods presented and Cash and cash equivalents and restricted cash at end of period for all periods presented includes Restricted cash of less than $0.03.

(1) |  | Arconic’s profit or loss measure for its reportable segments is Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization). The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) Research and development expenses, plus each of (i) Stock-based compensation expense, (ii) Metal price lag (see footnote 3), and (iii) Unrealized (gains) losses on mark-to-market hedging instruments and derivatives (see below). Arconic’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.
|  | Effective in the first quarter of 2022, management modified the Company’s definition of Segment Adjusted EBITDA to exclude the impact of unrealized gains and losses on mark-to-market hedging instruments and derivatives. This modification was deemed appropriate as Arconic is considering entering into additional hedging instruments in future reporting periods if favorable conditions exist to mitigate cost inflation. Certain of these instruments may not qualify for hedge accounting resulting in unrealized gains and losses being recorded directly to Sales or Cost of goods sold, as appropriate (i.e., mark-to-market). Additionally, this change was also applied to derivatives that do not qualify for hedge accounting for consistency purposes. The Company does not have a regular practice of entering into contracts that are treated as derivatives for accounting purposes. Ultimately, this change was made to maintain the transparency and visibility of the underlying operating performance of Arconic’s reportable segments. Prior to this change, the Company had a limited number of hedging instruments and derivatives that did not qualify for hedge accounting, the unrealized impact of which was not material to Arconic’s Segment Adjusted EBITDA performance measure. Accordingly, periods prior to the effective date of this change were not recast to reflect this change.
|  | Total Segment Adjusted EBITDA is the sum of the respective Segment Adjusted EBITDA for each of the Company’s three reportable segments: Rolled Products, Building and Construction Systems, and Extrusions. This amount is being presented for the sole purpose of reconciling Segment Adjusted EBITDA to the Company’s Consolidated net (loss) income.
(2) |  | Corporate expenses are composed of general administrative and other expenses of operating the corporate headquarters and other global administrative facilities.
(3) |  | Metal price lag represents the financial impact of the timing difference between when aluminum prices included in Sales are recognized and when aluminum purchase prices included in Cost of goods sold are realized. This adjustment aims to remove the effect of the volatility in metal prices and the calculation of this impact considers applicable metal hedging transactions.
(4) |  | For the quarters ended September 30, 2022 and 2021, see footnote 2 to the Statement of Consolidated Operations included in this release.
(5) |  | Other includes certain items that impact Cost of goods sold and Selling, general administrative, and other expenses on the Company’s Statement of Consolidated Operations that are not included in Segment Adjusted EBITDA, including those described as “Other special items” (see footnote 4 to the reconciliation of Adjusted EBITDA within Calculation of Non-GAAP Financial Measures included in this release).

Arconic’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for the following items: Provision for depreciation and amortization; Stock-based compensation; Metal price lag (see footnote 3); Unrealized (gains) losses on mark-to-market hedging instruments and derivatives (see below); and Other special items. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation and amortization. Special items are composed of restructuring and other charges, discrete income tax items, and other items as deemed appropriate by management. There can be no assurances that additional special items will not occur in future periods. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Arconic’s operating performance and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.
