Income before income taxes $ 295.2 $ 354.6 $ 233.4

Net income (loss) $ 130.9 $ (38.2)

Diluted net income (loss) per common share $ 0.96 $ (0.30)

Our major accomplishments during 2022 include the following:

• A return to profitability after a net loss in 2021, with 2022 net income of $131 million.

Sales in the fourth quarter 2022 were over $1 billion and net income was $77 million.

These results were driven by improved demand in key end markets, led by commercial jet engine products.

For the full year 2022, Adjusted EBITDA margins were 14.3%, a 390 basis point improvement from full year 2021.

• With the AA&S business transformation and footprint consolidation nearly complete, we are well positioned for continued future profitable growth.

In 2022, AA&S’s sales increased 33% to over $2 billion.

Aerospace and defense related sales in this segment increased 87% to $556 million.

Stronger sales volumes and the improved product mix led to AA&S EBITDA margin expansion exceeding 300 basis points compared to 2021.

• We generated positive cash flow of $225 million from operating activities in 2022, while supporting a $68 million increase in managed working capital and making a $50 million contribution to ATI’s U.S.

defined benefit pension trust.

As a result of our constant focus on our financial condition, we ended the year with $584 million of cash on hand and over $1 billion of total liquidity including the undrawn capacity under our asset-based lending facility.

• On May 12, 2022, we completed the sale of the Sheffield, UK operations, which was previously part of the HPMC segment.

With more than 80% of the operation’s $36 million 2021 sales focused on the oil and gas markets, it was not well-aligned with ATI’s strategic focus on the aerospace and defense markets.

This divestiture also removed all obligations for a UK defined benefit pension plan.

• On September 9, 2022, the Company amended and restated its Asset Based Lending (ABL) Credit Facility, which extended the ABL facility, including the $200 million term loan, through September 2027 and included an increase of $100 million in the revolving credit facility, to $600 million, and continued a letter of credit sub-facility of up to $200 million.

Diluted net income attributable to ATI per common share $ 2.81 $ 2.23 $ 1.32

* Fiscal years ended January 1, 2023 and January 2, 2022 reflect the change in accounting principle as described in Note 1 of the Notes to the Consolidated Financial Statements.

Our major accomplishments during fiscal year 2023 include the following:

• ATI delivered strong results for fiscal year 2023 as demand for our differentiated materials accelerates.

We finished the year strong with the highest quarterly revenue for fiscal year 2023 in the fourth quarter, marking the sixth quarter in a row exceeding $1 billion and the highest quarterly revenue since the second quarter of fiscal year 2019.

Sales to the aerospace and defense markets reached 59% of our sales for the full fiscal year 2023, up 10 percentage points over the prior year, as we are progressing quickly towards our goal of 65% of sales to these markets.

• Growth in the aerospace and defense markets drove strong results in our HPMC segment, with sales up 29% and HPMC EBITDA up 43% in fiscal year 2023 compared to fiscal year 2022.

EBITDA margins in this segment improved by 200 basis points to 20.5% in fiscal year 2023.

Full fiscal year 2023 commercial airframe product sales in this segment were up 90% year over year, reflecting the strong demand for our materials as the aerospace ramp continues.

• Sales of titanium products reached 17% of total sales in fiscal year 2023, up from 11% in the prior year, as these products remain a focal point across the aerospace & defense industry.

We restarted a significant amount of titanium melt capacity in Albany, OR in fiscal year 2023, and we are on track for the first melt in the fourth quarter of fiscal year 2024 at our Richland, Washington facility.

When our Richland, Washington expansion is at full production in late fiscal year 2025, our total titanium melt capacity is expected to be 80% greater than our fiscal year 2022 titanium melt capacity.

• We generated cash flow of $85.9 million from operating activities in fiscal year 2023, despite making contributions of $272 million to our U.S.

qualified defined benefit pension plans.

Continued efforts to focus on operational improvements are positively impacting the inventory intensity of our business and alleviating the required investment of managed working capital in our growing business.

Managed working capital as a percent of sales was 31.1% as of December 31, 2023.

We ended the year with $744 million of cash on hand and over $1 billion of total liquidity including the undrawn capacity under our asset-based lending facility.

• In the fourth quarter, we transferred approximately 85% of our U.S.

qualified defined benefit pension plan obligations and related assets to a third-party insurance company through the purchase of group annuity contracts.

Under these contracts, we transferred the pension obligations and associated assets for approximately 8,200 plan participants to the selected insurance company.

After these actions, our U.S.

qualified defined benefit pension plan includes approximately 1,980 participants.

In addition, as of December 31, 2023, our U.S.

qualified defined benefit pension plan is 114% funded on a financial reporting basis.

As a result, based on current actuarial assumptions, we are not anticipating any significant required cash contributions in at least the next ten years.

Our consolidated net pension liability, inclusive of obligations related to our qualified and nonqualified defined benefit pension plans, was $9 million, or 97% funded on a financial reporting basis, a significant improvement compared to a $219 million liability, or 88% funded position, at January 1, 2023.

• We repurchased 2 million shares of ATI stock for $85 million in fiscal year 2023, using all the remaining $150 million and $75 million under the plans approved by our Board of Directors in fiscal years 2022 and 2023, respectively.

In addition, in November 2023, our Board of Directors authorized the repurchase of an additional $150 million of ATI stock.

• In August 2023, we issued $425 million aggregate principal amount of 7.25% Senior Notes due 2030 (2030 Notes).

The net proceeds from this issuance were used to fund ATI’s U.S.

qualified defined benefit pension plan in order to facilitate the pension derisking strategy discussed above.

• $26.8 million of pension remeasurement losses for the immediate recognition in earnings of the actuarial gains/losses from the remeasurement of the projected benefit obligation and plan assets for defined benefit pension plans in accordance with our newly adopted accounting principle.

These losses are from the remeasurements of these plans in the fourth quarter of fiscal year 2023.

Results for fiscal year 2022 also included $27.9 million of net pre-tax charges which consisted of the following:

• $105.4 million in losses, net, primarily associated with the sale of the Sheffield, UK business which was sold in May 2022 for a $112.2 million loss.

EBITDA and Adjusted EBITDA are measures utilized by ATI that we believe 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 non-GAAP measures and are not intended to represent, and should not be considered more meaningful than, or as alternatives to, a measure of operating performance as determined in accordance with U.S.

generally accepted accounting principles (U.S.

We categorically define EBITDA as income from continuing operations before interest and income taxes, plus depreciation and amortization, goodwill impairment charges and debt extinguishment charges.

We categorically define Adjusted EBITDA as EBITDA excluding significant non-recurring charges or credits, restructuring charges/credits, strike related costs, long-lived asset impairments, pension remeasurement gains and losses, and other postretirement/pension curtailment and settlement gains and losses.

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.

As part of managing the liquidity of our business, we focus on controlling managed working capital, which is defined as gross accounts receivable, short-term contract assets and gross inventories, less accounts payable and short-term contract liabilities.

In measuring performance in controlling this managed working capital, we exclude the effects of inventory valuation reserves, and reserves for uncollectible accounts receivable which, due to their nature, are managed separately.

We measure managed working capital as a percentage of the prior three months annualized sales to evaluate our performance based on recent levels of business volume.

In 2022, managed working capital decreased to 30.1% of annualized total ATI sales compared to 37.5% of annualized sales at December 31, 2021, reflecting the Company’s ongoing efforts to improve managed working capital efficiency as well as a higher level of sales.

The $67.5 million increase in overall managed working capital in 2022 is detailed in the table below.

Days sales outstanding, which measures actual collection timing for accounts receivable, modestly improved at year-end 2022 compared to 2021.

Gross inventory turns improved by 13% in 2022 compared to 2021, as improved inventory flow across our operations was an area of significant management focus in 2022.

Accounts payable increased as a result of increased business volumes in 2022 and capital expenditures related to strategic projects that remained in accounts payable at December 31 2022.

The computations of Managed Working Capital at December 31, 2022 and 2021, reconciled to the financial statement line items as computed under U.S.

*Fiscal years ended January 1, 2023 and January 2, 2022 reflect the change in accounting principle as described in Note 1 of the Notes to the Consolidated Financial Statements.

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.

In fiscal year 2023, Managed Working Capital increased to 31.1% of annualized total ATI sales compared to 30.1% of annualized sales at January 1, 2023.

The Managed Working Capital increase was impacted by increased inventory levels in fiscal year 2023 as a result of additional melt capacity coming on line and increased production levels.

The $106.7 million increase in overall managed working capital in fiscal year 2023 is detailed in the table below.

Days sales outstanding, which measures actual collection timing for accounts receivable, improved by 7% as of December 31, 2023 compared to fiscal year 2022.

Gross inventory turns as of December 31, 2023 remained consistent with January 1, 2023 as continued efforts to focus on operational improvements are positively impacting the inventory intensity of our business and alleviating the required investment of managed working capital in our growing business.

The decrease in interest expense in fiscal year 2022 compared to fiscal year 2021 was in part due to the conversion of $82.5 million of the 4.75% Convertible Senior Notes due 2022 (2022 Notes) to 5.7 million shares of ATI stock on the July 1, 2022 maturity date of the 2022 Notes.

Further, interest expense is presented net of interest income of $13.0 million in fiscal year 2023, $4.7 million in fiscal year 2022 and $0.7 million in fiscal year 2021.

Interest expense in fiscal years 2023, 2022 and 2021 was reduced by $13.5 million, $5.1 million and $4.3 million, respectively, related to interest capitalization on major strategic capital projects.

Retirement Benefits

All of ATI’s defined benefit pension plans are now closed to new entrants, and at most ATI operations with pension participants, the plans are frozen for all future benefit accruals, with less than 10% of participants in ATI’s U.S.

qualified defined benefit plans still earning additional pension service.

Additionally, all of the remaining collectively-bargained defined benefit retiree health care plans at ATI’s operations are now closed to new entrants, with cost caps in place for these obligations.

All of ATI’s defined benefit pension plans are closed to new entrants, and at most ATI operations with pension participants, the plans are frozen for all future benefit accruals, with less than 800 participants still accruing benefit service.

Additionally, all of the remaining collectively-bargained defined benefit retiree health care plans at ATI’s operations are now closed to new

entrants, with cost caps in place for these obligations.

As a result of these actions, ATI’s retirement savings and other postretirement benefit programs have largely transitioned to a defined contribution structure.

Since 2013, five annuity buyouts of retired participants and two voluntary cash out programs of deferred participants during this period have helped to reduce the total participants in ATI’s U.S.

From fiscal years 2013 to 2022, five annuity buyouts of retired participants and two voluntary cash out programs of deferred participants during this period helped to reduce the total participants in ATI’s U.S.

qualified defined benefit pension plans by more than 60%.

During the fourth quarter of fiscal year 2023, we purchased group annuity contracts from an insurer covering approximately 85% of our U.S.

qualified defined benefit pension plan obligations.

Under these contracts, we transferred the pension obligations and associated assets for approximately 8,200 plan participants to the selected insurance company.

To facilitate this pension derisking strategy, we completed a voluntary cash out for term vested employees and contributed $222 million to our pension plan in the third quarter of fiscal year 2023, to fully fund remaining pension liabilities ahead of this annuity transaction.

After these actions, our U.S.

qualified defined benefit pension plan includes approximately 1,980 participants.

At December 31, 2023, our defined benefit pension plans were approximately 97% funded in accordance with generally accepted accounting principles, and were remeasured at that date using a 5.60% discount rate to measure the projected benefit obligation.

Funding requirements are also affected by IRS-determined mortality assumptions, which may differ from those used under accounting standards.

As a result of the ARPA enacted in March 2021, the rules governing pension funding calculations changed.

Based on current actuarial assumptions, we are not required to make any contributions to our pension plan during fiscal year 2024, and we are not required to make any significant contributions for at least the next ten years.

However, these estimates are subject to significant uncertainty, including the performance of our pension trust assets and the discount rates used to measure pension liabilities.

Pension trust asset performance for both our accounting and ERISA funding calculations is determined using the market value of plan assets at the end of each year.

We have certain CBAs that include participation in a multiemployer pension plan.

Under current law, an employer that withdraws or partially withdraws from a multiemployer pension plan may incur a withdrawal liability to the plan, which represents the portion of the plan’s underfunding that is allocable to the withdrawing employer under very complex actuarial and allocation rules.

A subsidiary of the Company participates in the Steelworkers Western Independent Shops Pension Plan (WISPP) for union-represented employees of our primary titanium operations in Albany, OR, which is funded on an hours-worked basis.

Manufacturing operations at this facility have been idled throughout 2021 and most of 2022, with a limited number of employees that participate in the WISPP remaining active in maintenance and other functions.

It is reasonably possible that a significant reduction or the elimination of hours-worked contributions due to changes in operating rates at this facility could result in a withdrawal liability assessment in a future period.

A complete withdrawal liability is estimated to be approximately $27 million on an undiscounted basis, based on information for the plan year ended September 30, 2021, which

is the most recent information available from the Plan Administrator.

If this complete withdrawal liability was incurred, ATI estimates that payments of the obligation would be required on a straight-line basis over a 15-year period.

Future cash flow value may include appraisals for property, plant and equipment, land and improvements, future cash flow estimates from operating the long-lived assets, and other operating considerations.

On December 2, 2020, we announced a strategic repositioning of our SRP business within the AA&S segment, with a focus of increasing emphasis on the specialty rolled products portion of its product portfolio, which comprise titanium-based alloys including aerospace-grade titanium plate products, nickel-based alloys, and stainless products with more differentiated characteristics for specialty applications, including thin-gauge PRS.

The December 2, 2020 decision to exit production of standard stainless products represented a significant indicator of impairment in the carrying value of certain long-lived assets.

Based on projected cash flows of the Brackenridge, PA operations, including the HRPF, we completed a fair value analysis as of the beginning of the fourth quarter of 2020 and recognized a $1,032.6 million impairment charge for this facility based on an estimated fair value of $354 million.

This long-lived asset impairment charge was determined using a held in use framework and an income approach, which represents Level 3 unobservable information in the fair value hierarchy.

This impairment assessment and valuation method require us to make estimates and assumptions regarding future operating results, cash flows, changes in working capital and capital expenditures, selling prices, profitability, and the cost of capital.

Many of these assumptions are determined by reference to market participants we have identified.

For example, the weighted average cost of capital (WACC) used in our discounted cash flow assessment was 9.3% and the long-term growth rate was 2%.

Although we believe that the estimates and assumptions used were reasonable, actual results could differ from those estimates and assumptions.

Goodwill is reviewed annually in the fourth quarter of each year for impairment or more frequently if impairment indicators arise.

As of April 3, 2022, our Sheffield, UK operations were classified as held for sale, and the terms of sale resulted in indicators of impairment in the long-lived assets of this disposal group.

A $22.3 million long-lived asset impairment charge was recorded in the first quarter of fiscal year 2022, reported as part of the $112.2 million loss on sale of this business for the fiscal year ended January 1, 2023.

This long-lived asset impairment charge was determined using the held for sale framework and represents Level 1 information in the fair value hierarchy.

Goodwill is reviewed annually in the fourth quarter of each fiscal year for impairment or more frequently if impairment indicators arise.

Other events and changes in circumstances may also require goodwill to be tested for impairment between annual measurement dates.

At December 31, 2023, the Company had $227.2 million of goodwill on its consolidated balance sheet, all of which relates to the HPMC segment.

Goodwill decreased $0.7 million in 2022 due to foreign currency translation on goodwill denominated in functional currencies other than the U.S.

For our annual goodwill impairment evaluation performed in the fourth quarter of 2022, quantitative goodwill assessments were performed for the two HPMC reporting units with goodwill.

Fair values were determined by using a quantitative assessment that may include discounted cash flow and multiples of cash earnings valuation techniques, plus valuation comparisons to recent public sale transactions of similar businesses, if any, which represents Level 3 unobservable information in the fair value hierarchy.

For example, our WACC used in our discounted cash flow assessments was 12.0% and long-term growth rates ranged from 3% to 3.5%.

The estimated effect of a 0.50% change in the WACC would result in a 10% change in the fair value of the Forged Products reporting unit.

The estimated effect of a 0.50% change in the WACC would result in a 10% change in the fair value of the Forged

Products reporting unit.

Although we believe that the estimates and assumptions used were reasonable, actual results could differ from those estimates and assumptions.

The $227.2 million of goodwill remaining as of December 31, 2023 on our consolidated balance sheet is comprised of $161.2 million at the Forged Products reporting unit and $66.0 million at the Specialty Materials reporting unit.

For our annual goodwill impairment evaluation performed in the fourth quarter of 2022, the Specialty Materials reporting unit had a fair value that was significantly in excess of carrying value.

The Forged Products reporting unit had a fair value that exceeded carrying value by more than 50% for the 2022 annual assessment, which increased compared to the annual evaluation for 2021.

As a result, no impairments were determined to exist from the annual goodwill impairment evaluation for the years ended

December 31, 2022, 2021 or 2020.

For our annual goodwill impairment evaluation performed in the fourth quarter of fiscal year 2023, the Specialty Materials reporting unit had a fair value that was significantly in excess of carrying value.

The Forged Products reporting unit had a fair value that exceeded carrying value by approximately 60% for the fiscal year 2023 annual assessment, which increased compared to the annual evaluation for fiscal year 2022.

As a result, no impairments were determined to exist from the annual goodwill impairment evaluation for the fiscal years ended December 31, 2023, January 1, 2023 or January 2, 2022.

In order to validate the reasonableness of the estimated fair values of the reporting units as of the valuation date, a reconciliation of the aggregate fair values of all reporting units to market capitalization was performed using a reasonable control premium.

In addition, no indicators of impairment were observed in 2022 or 2021 associated with any of our long-lived assets in the HPMC segment.

During the second quarter of 2020, we performed an interim goodwill impairment analysis on the Forged Products reporting unit and its $460.4 million goodwill balance based on assessed potential indicators of impairment, including recent disruptions to the global commercial aerospace market resulting from the COVID-19 pandemic, and the increasing uncertainty of near-term demand requirements of aero-engine and airframe markets based on government responses to the pandemic and ongoing interactions with customers.

For the 2020 interim impairment analysis, fair value was determined by a quantitative assessment that used a discounted cash flow technique.

As a result of the second quarter 2020 interim goodwill impairment evaluation, we determined that the fair value of the Forged Products reporting unit was below carrying value, including goodwill, by $287.0 million.

This was primarily due to changes in the timing and amount of expected cash flows resulting from lower projected revenues, profitability and cash flows due to near-term reductions in commercial aerospace market demand.

Consequently, during the second quarter of 2020, we recorded a $287.0 million impairment charge for the partial impairment of Forged Products reporting unit goodwill, most of which was assigned from the Company’s 2011 Ladish acquisition that was not deductible for income tax purposes.

In addition, no indicators of impairment were observed in fiscal years 2023 or 2022 associated with any of our long-lived assets.

Valuation allowances are established when it is estimated that it is more likely than not that the tax benefit of the deferred tax asset will not be realized.

Results in 2022, 2021 and 2020 include impacts from income taxes that differ from applicable standard tax rates, primarily related to income tax valuation allowances.

In 2020, ATI’s U.S.

operations returned to a three-year cumulative loss position, limiting our ability to utilize future projections as sources of income when analyzing the need for a valuation allowance.

The consolidated income tax provision of $77.7 million for fiscal year 2020 primarily relates to increases to deferred tax asset valuation allowances based on an analysis of the expected realization of deferred tax assets and liabilities within applicable expiration periods.

In 2021 and 2022, ATI continued to maintain income tax valuation allowances on its U.S.

Federal and state deferred tax assets.

Since fiscal year 2020, ATI’s U.S.

operations were in a three-year cumulative loss position, limiting the ability to utilize future projections as verifiable sources of income when analyzing the need for a valuation allowance.

Results in fiscal years 2021 and 2022 include impacts from income taxes that differ from applicable standard tax rates, primarily related to these income tax valuation allowances.

We determined that valuation allowances on net deferred tax asset balances for federal and certain state jurisdictions are no longer required.

Certain individual tax attributes still require a valuation allowance based on expected utilization.

At December 31, 2023, our deferred tax asset valuation allowance was $60.3 million.

In fiscal year 2023, ATI recorded a tax benefit associated with the valuation allowance due to the current year income for the U.S.

operations and an additional benefit was recorded related to the valuation allowance release associated with ATI’s ability to utilize projections for future income.

In addition, we have $24.1 million of valuation allowances on amounts recorded in other comprehensive loss on the consolidated balance sheet as of December 31, 2023.

While we remain in a cumulative loss condition, our ability to evaluate the realizability of deferred tax assets is generally limited to the ability to offset timing differences on taxable income associated with deferred tax liabilities.

Therefore, a change in estimate of deferred tax asset valuation allowances for federal, state, or foreign jurisdictions during this cumulative loss condition period will primarily be affected by changes in estimates of the time periods that deferred tax assets and liabilities will be realized, or on a limited basis to tax planning strategies that may result in a change in the amount of taxable income realized.

In establishing the expected return on plan investments, which is reviewed annually in the fourth quarter, we take into consideration input from our third-party pension plan asset managers and actuaries regarding the types of securities the plan assets are invested in, how those investments have performed historically, and expectations for how those investments will perform in the future.

Our weighted average expected long-term return on pension plan investments was 6.43% in 2022, and the weighted average expected long-term rate of return on pension plan investments for 2023 will be 6.57%.

Our weighted average expected long-term return on pension plan investments was initially 6.57% in

fiscal year 2023, and 5.80% upon remeasurement as of October 17, 2023, following the large annuity buyout of retirees.

The expected long-term rate of return on pension plan investments for fiscal year 2024 will be 5.80%.

We apply the assumed rate of return to the market value of plan assets at the end of the previous year.

This produces the expected return on plan assets that is included in annual pension expense for the current year.

The actual returns on pension plan assets for the last five years have been (14.5)% for 2022, 12.4% for 2021, 15.2% for 2020, 15.1% for 2019, and (4.8)% for 2018.

The actual returns on pension plan assets for the last five fiscal years have been 2.0% for 2023, (14.5)% for 2022, 12.4% for 2021, 15.2% for 2020, and 15.1% for 2019.

The effect of increasing, or lowering, the expected return on pension plan investments by 0.25% would result in additional pre-tax annual income, or expense, of approximately $1 million.

The cumulative difference between the expected return and the actual return on plan assets is deferred and amortized into pension income or expense over future periods.

The cumulative difference between the expected return and the actual return on plan assets is immediately recognized in earnings through net periodic pension benefit cost within nonoperating retirement benefit expense on the consolidated statements of operations when pension plans are remeasured annually in the fourth quarter or on an interim basis as triggering events require remeasurement.

This immediate recognition is in accordance with the accounting standards and is a result of our change in accounting principle in the fourth quarter of fiscal year 2023 as discussed in Note 1 to the Consolidated Financial Statements.

The amount of expected return on plan assets can vary significantly from year-to-year since the calculation is dependent on the market value of plan assets as of the end of the preceding year.

In estimating this rate, we receive input from our actuaries regarding the rates of return on high quality, fixed-income investments with maturities matched to the expected future retirement benefit payments.

Based on this assessment, we established a discount rate of 5.55% for valuing the pension liabilities as of December 31, 2022, and for determining the pension expense for 2023.

We had previously assumed a discount rate of 2.95% at the end of 2021 and 2.60% at the end of 2020.

Based on this assessment, we established a discount rate of 5.60% for valuing the pension liabilities as of December 31, 2023, and for determining the pension expense for fiscal year 2024.

We had previously assumed a discount rate of 5.55% at the end of fiscal year 2022, which changed to 6.40% upon the remeasurement as of October 17, 2023, following the large annuity buyout of retirees, and 2.95% at the end of fiscal year 2021.

The estimated effect of changing the discount rate by 0.50% would decrease pension liabilities in the case of an increase in the discount rate or increase pension liabilities in the case of a decrease in the discount rate, by approximately $20 million.

Such a change in the discount rate would decrease pension expense in the case of an increase in the discount rate, or increase pension expense in the case of a decrease in the discount rate, by less than $2 million.

The effect on pension liabilities for changes to the discount rate, as well as the net effect of other changes in actuarial assumptions and experience, are deferred and amortized over future periods in accordance with the accounting standards.

As discussed above, gains and losses due to differences between actual and expected results for investment returns on plan assets, changes in the discount rate used to value benefit obligations, and other changes in estimates such as participant life expectancy are deferred and recognized in the consolidated statement of operations over future periods.

However, for balance sheet presentation, these gains and losses are included in the determination of benefit obligations, net of plan assets, included on the year-end consolidated balance sheet.

At December 31, 2022, the Company had approximately $1.2 billion of pre-tax net actuarial losses on its pension obligations, primarily related to an extended decline in prior years in the discount rate used to value the pension obligations.

These actuarial losses have been recognized on the consolidated balance sheet through a reduction in stockholders’ equity, and are being recognized in the consolidated statement of operations through expense amortizations over future years.

Due to all of ATI’s defined benefit plans being closed to new entrants, with the population predominately frozen for future benefit accruals, the amortization period for accumulated other comprehensive loss recognition for all of these plans is average remaining life expectancy, which is approximately 17 years on a weighted average basis.

Such a change in the discount rate would have an insignificant impact to pension expense.

The effect on pension liabilities for changes to the discount rate, as well as the net effect of other changes in actuarial assumptions and experience, are immediately recognized in earnings through net periodic pension benefit cost within nonoperating retirement benefit expense on the consolidated statements of operations when pension plans are remeasured annually in the fourth quarter or on an interim basis as triggering events require remeasurement.

The discount rate, which is determined annually at the end of each fiscal year, is developed based upon rates of return on high quality, fixed-income investments.

At the end of 2022, we determined the rate to be 5.45%, compared to a 2.80% discount rate in 2021, and a 2.45% discount rate in 2020.

At the end of fiscal year 2023, we determined the rate to be 5.40%, compared to a 5.45% discount rate in fiscal year 2022, and a 2.80% discount rate in fiscal year 2021.

The estimated effect of changing the discount rate by 0.50% would decrease postretirement obligations in the case of an increase in the discount rate or increase postretirement obligations in the case of a decrease in the discount rate, by approximately $7 million.

Such a change in the discount rate would decrease postretirement benefit expense in the case of an increase in the discount rate, or increase postretirement benefit expense in the case of a decrease in the

discount rate, by less than $1 million.

Such a change in the discount rate would have an insignificant impact to postretirement benefit expense.

Based upon predictions of continued significant medical cost inflation in future years, the annual assumed rate of increase in the per capita cost of covered benefits of health care plans is 7.2% in 2024 and is assumed to gradually decrease to 4.0% in the year 2048 and remain level thereafter.
