“Our third quarter financial results reflect the benefits of ATI's strategy to focus on aerospace and defense, markets that continue to send very strong demand signals," said Robert S. Wetherbee, Board Chair, President and CEO. “HPMC continued its strong upward trend with ramping commercial aerospace demand. AA&S results reflect planned seasonal maintenance outages in our U.S. operations, as well as Covid-related headwinds at our Asian precision rolled strip business.

“We continue to deliver on commitments to our customers, while accelerating cash generation. As we experience double-digit revenue growth, we're also improving working capital management and continue to prioritize disciplined capital deployment."

Operating Results by Segment

High Performance Materials & Components (HPMC)
($ millions)	Q3 2022		Q2 2022		Q3 2021
Sales	$457.6		$396.1		$300.0
Segment EBITDA	$85.8		$60.3		$37.4
% of Sales	18.8	%	15.2	%	12.5	%

•HPMC's third quarter 2022 sales increased 16% compared to the second quarter 2022 as commercial aerospace sales increased 22%, led by continued increasing demand for jet engine products. Overall aerospace and defense sales were 82% of total HPMC sales in the third quarter 2022. Sales improved 53% compared to the third quarter 2021, with sales of commercial aerospace products increasing by 116% compared to the prior year period.

•HPMC segment EBITDA was $85.8 million, or 18.8% of sales. Strong operating margin growth reflects higher sales of next-generation jet engine products and higher operating levels. Third quarter 2022 results did not include any benefits from Covid relief programs, whereas the second quarter 2022 included $5.6 million of these benefits.

Advanced Alloys & Solutions (AA&S)
($ millions)	Q3 2022		Q2 2022		Q3 2021
Sales	$574.4		$563.4		$425.7
Segment EBITDA	$75.8		$104.6		$56.8
% of Sales	13.2	%	18.6	%	13.3	%

•AA&S third quarter 2022 sales increased 2% compared to the second quarter 2022 and increased 35% compared to the prior year quarter. Third quarter 2021 was impacted by a strike at our Specialty Rolled Products business, which largely returned to normal operations by end of the prior year quarter. Compared to the second quarter 2022, sales to the aerospace and defense markets were 30% higher, led by demand for commercial airframe products. Third quarter sales to the energy markets were in-line with the second quarter 2022. Sales at our Asian precision rolled strip business continue to be negatively impacted by Covid-related market interruptions.

•AA&S segment EBITDA was $75.8 million, or 13.2% of sales. Compared to the second quarter 2022, a weaker mix of nickel-alloy mill products, declining raw material surcharges and lower utilization rates resulting from our annually planned, six-week maintenance outage at our Specialty Alloys & Components business resulted in lower margins in the third quarter 2022. Second quarter

2022 AA&S results included a $9.9 million benefit from the A&T Stainless joint venture's settlement of Section 232 claims. Prior year AA&S results exclude $21.5 million of strike-related costs.

Corporate Items and Cash

•Restructuring and other charges in the third quarter 2022 included $19.9 million in connection with the settlement of litigation related to the 2016 indefinite idling of the Rowley, UT titanium sponge production facility. Restructuring credits of $2.6 million were also recognized in the third quarter 2022 related to reversals of previously-recognized reserves, due to lower than expected severance-related costs. Results for the third quarter of 2021 include $22.9 million of strike-related costs, primarily affecting the AA&S segment, which were excluded from segment and ATI adjusted EBITDA.

•Second quarter and nine months' 2022 results include $115.9 million and $141.0 million, respectively, of non-cash losses on the May 12, 2022 sale of the Sheffield, UK operations.

•Third quarter 2021 results included a $64.9 million gain related to a plan termination that eliminated certain postretirement medical benefit liabilities. Prior year results also included a $13.7 million gain on the sale of the Flowform Products business.

•Corporate expenses in the third quarter 2022 were $14.2 million, compared to $16.7 million in the second quarter 2022, and $12.9 million for the prior year quarter. Lower sequential corporate expenses in 2022 were primarily related to benefits from corporate owned life insurance.

•Closed operations and other expenses were $6.3 million for the third quarter 2022, compared to $5.1 million in the second quarter 2022 and $1.4 million in the prior year quarter. Higher costs in 2022 periods are primarily related to foreign currency remeasurement impacts primarily related to ATI’s European Treasury operation and higher legal costs of closed operations.

•Third quarter 2022 results include a $3.0 million income tax provision, primarily related to our Asian precision rolled strip business. Third quarter 2021 income tax expense included $15.5 million in discrete tax effects related to the postretirement medical benefits gain. ATI maintains a valuation allowance on its U.S. deferred tax assets and does not expect to pay any significant U.S. federal or state income taxes for the next several years due to net operating loss carryforwards.

•For the third quarter of 2022, cash provided by operating activities was $123.0 million, and cash used in operations was $99.4 million on a year-to-date basis. Third quarter 2022 managed working capital as a percent of sales decreased 200 basis points to 36.5% sequentially as the operating efficiency of the business improved. Capital expenditures were $100.5 million in the first nine months of 2022.

•Cash on hand at September 30, 2022 was $329.1 million, and available additional liquidity under the asset-based lending (ABL) credit facility was approximately $550 million. In the third quarter of 2022, ATI amended and extended the ABL for a five-year term, including a $100 million capacity increase in the revolving credit facility and extending the $200 million Term Loan maturity to 2027. ATI has no significant debt maturities until 2025.

Outlook

“The deliberate actions we have taken to transform our sales mix and operations have continued to reduce volatility and make us more resilient against potential macroeconomic headwinds. This gives ATI stability well into the future," said Wetherbee. "At the same time, we recognize there are uncertainties that may impact our growth rates in the near-term. We expect ongoing strength in our key markets, particularly aerospace & defense, to drive profitable revenue growth. Our recent results demonstrate the progress we are making toward our long-term financial targets, delivering value to our shareholders."

ATI Inc.

Non-GAAP Financial Measures

(Unaudited, dollars in millions, except per share amounts)

The Company reports its financial results in accordance with accounting principles generally accepted in the United States of America (“GAAP”). However, management believes that certain non-GAAP financial measures, used in managing the business, may provide users of this financial information with additional meaningful comparisons between current results and results in prior periods. For example, we believe that EBITDA and Adjusted EBITDA are useful to investors because these measures are commonly used to analyze companies on the basis of operating performance, leverage and liquidity. Furthermore, analogous measures are used by industry analysts to evaluate operating performance. EBITDA and Adjusted EBITDA are not intended to be measures of free cash flow for management’s discretionary use, as they do not consider certain cash requirements such as interest payments, tax payments and capital expenditures. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP. The following table provides the calculation of the non-GAAP financial measures discussed in the Company's press release dated November 2, 2022:

Managed Working Capital

As part of managing the performance of our business, we focus on controlling Managed Working Capital, which we define as gross accounts receivable, short-term contract assets and gross inventories, less accounts payable and short-term contract liabilities. We exclude the effects of inventory valuation reserves and reserves for uncollectible accounts receivable when computing this non-GAAP performance measure, which is not intended to replace Working Capital or to be used as a measure of liquidity. We assess Managed Working Capital performance as a percentage of the prior three months annualized sales to evaluate the asset intensity of our business.
