CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report contains information that may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend the forward-looking statements to be covered by the safe harbor provisions for forward-looking statements in those sections. Generally, we have identified such forward-looking statements by using the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “target,” “forecast,” “aim,” “should,” “plan,” “goal,” “future,” “will,” "may" and similar expressions or by using future dates in connection with any discussion of, among other things, the construction or operation of new or existing facilities or operating capabilities, the timing, size and form of share repurchase transactions, operating or financial performance, trends, events or developments that we expect or anticipate will occur in the future, statements relating to volume changes, share of sales and earnings per share changes, anticipated cost savings, potential capital and operational cash improvements, changes in the global economic environment, including supply and demand conditions, inflation, interest rates, supply chain disruptions and changes in prices for our products, international trade duties and other aspects of international trade policy, statements regarding our future strategies, products and innovations, statements regarding our greenhouse gas emissions reduction goals, statements regarding existing or new regulations and statements expressing general views about future operating results. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are not historical facts, but instead represent only the Company’s beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of the Company’s control. It is possible that the Company’s actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements. Management believes that these forward-looking statements are reasonable as of the time made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made. Our Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our Company's historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to, the risks and uncertainties described in this report and in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and those described from time to time in our future reports filed with the Securities and Exchange Commission.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Basis of Presentation and Significant Accounting Policies

The year-end Consolidated Balance Sheet data was derived from audited statements but does not include all disclosures required for complete financial statements by accounting principles generally accepted in the United States of America (U.S. GAAP). The other information in these condensed financial statements is unaudited but, in the opinion of management, reflects all adjustments necessary for a fair statement of the results for the periods covered, including assessment of certain accounting matters using all available information such as consideration of forecasted financial information in context with other information reasonably available to us. However, our future assessment of our current expectations could result in material impacts to our consolidated financial statements in future reporting periods. All such adjustments are of a normal recurring nature unless disclosed otherwise. These condensed financial statements, including notes, have been prepared in accordance with the applicable rules of the Securities and Exchange Commission and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. Additional information is contained in the United States Steel Corporation Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which should be read in conjunction with these condensed financial statements.

2. New Accounting Standards

During the three months ended March 31, 2023, there were no accounting standards and interpretations issued which are expected to have a material impact on the Company's financial position, operations or cash flows.

3. Recently Adopted Accounting Standards

In September 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2022-04, Disclosure of Supplier Finance Program Obligations (ASU 2022-04). ASU 2022-04 requires that an entity disclose certain information about supplier finance programs used in connection with the purchase of goods and services. ASU 2022-04 is effective for all entities with fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. U. S. Steel adopted this guidance effective January 1, 2023, with the exception of the amendment on roll-forward information, which will be adopted in our fiscal year beginning on January 1, 2024.

The Company has a supply chain finance (SCF) arrangement with a third-party administrator which allows participating suppliers, at their sole discretion, to make offers to sell payment obligations of the Company prior to their scheduled due dates at a discounted price to a participating financial institution. The third-party administrator entered into a separate agreement with the Export Import Bank of the United States to guarantee 90 percent of supplier obligations sold for up to $200 million. No guarantees or collateral are provided by the Company or any of its subsidiaries under the SCF program.

The Company’s goal is to capture overall supplier savings and improve working capital efficiency. The agreements facilitate the suppliers’ ability to sell payment obligations, while providing them with greater working capital flexibility. The Company has no economic interest in the sale of the suppliers’ receivables and no direct financial relationship with the financial institution concerning these services. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to sell amounts under the arrangements. The SCF program requires the Company to pay the third-party administrator the stated amount of the confirmed participating supplier invoices. The payment terms for confirmed invoices range from 75 to 90 days after the end of the month in which the invoice was issued.

The underlying costs from suppliers that elected to participate in the SCF program are generally recorded in cost of sales in the Company’s Condensed Consolidated Statement of Operations. Amounts due to suppliers who participate in the SCF program are reflected in accounts payable and accrued expenses on the Company’s Condensed Consolidated Balance Sheet and payments on the obligations by our suppliers are included in cash used in operating activities in the Condensed Consolidated Statement of Cash Flows. As of March 31, 2023, accounts payable and accrued expenses included $107 million of outstanding payment obligations which suppliers elected to sell to participating financial institutions.

In October 2021, the FASB issued Accounting Standards Update 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (ASU 2021-08). ASU 2021-08 requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. ASU 2021-08 is effective for public companies with fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption of all amendments in the same period permitted. U. S. Steel adopted this guidance effective January 1, 2023 and will apply it to any future business combinations.

4. Segment Information

U. S. Steel has four reportable segments: North American Flat-Rolled (Flat-Rolled), Mini Mill, U. S. Steel Europe (USSE); and Tubular Products (Tubular). The results of our real estate businesses are disclosed in the Other category.

-5-

The chief operating decision maker evaluates performance and determines resource allocations based on a number of factors, the primary measure being earnings (loss) before interest and income taxes. Earnings (loss) before interest and income taxes for reportable segments and the Other category does not include net interest and other financial costs (income), income taxes, stock-based compensation expense, and certain other items that management believes are not indicative of future results.

The accounting principles applied at the operating segment level in determining earnings (loss) before interest and income taxes are generally the same as those applied at the consolidated financial statement level. Intersegment sales and transfers are accounted for at market-based prices and are eliminated at the corporate consolidation level. Corporate-level selling, general and administrative expenses and costs related to certain former businesses are allocated to the reportable segments and Other based on measures of activity that management believes are reasonable.

The results of segment operations for the three months ended March 31, 2023 and 2022 are:


(In millions) Three Months Ended March 31, 2023	Customer Sales		Intersegment Sales		Net Sales		(Loss) earnings from investees		(Loss) earnings before interest and income taxes(a)

Total	$	5,234	$	—	$	5,234	$	36	$	1,118
(a) (Loss) earnings before interest and income taxes has been updated for three months ended March 31, 2022 for Flat-Rolled and Reconciling Items and Eliminations. This is the result of a retroactive adjustment for the reclassification of stock-based compensation expense as an item not allocated to segment results. See the schedule of reconciling items to consolidated earnings before interest and income taxes below for further details.

A summary of total assets by segment is as follows:


(In millions)	March 31, 2023		December 31, 2022
Flat-Rolled	$	8,109	$	7,936
Mini Mill(a)	6,176		5,787
USSE	6,199		5,823
Tubular	1,163		1,140
Total reportable segments	$	21,647	$	20,686
Other	$	142	$	141
Corporate, reconciling items, and eliminations(b)	(2,249)		(1,369)
Total assets	$	19,540	$	19,458

(a)Includes assets of $1.7 billion and $1.4 billion at March 31, 2023 and December 31, 2022, respectively, related to Big River 2 (BR2) under construction in Osceola, Arkansas.

-6-

(b)The majority of corporate, reconciling items, and eliminations is comprised of cash and the elimination of intersegment amounts.

The following is a schedule of reconciling items to consolidated earnings before interest and income taxes:


	Three Months Ended March 31,
(In millions)	2023		2022
Items not allocated to segments:
Restructuring and other charges (Note 20)	$	(1)	$	(17)
Stock-based compensation expense (Note 11)	(11)		(16)

Other charges, net	(5)		(4)
Total reconciling items	$	(17)	$	(37)

5. Disposition

The Company has previously committed to, and continues to intend to, pursue the disposition of certain assets related to a component of its flat-rolled business. As of March 31, 2023, the Company accrued a total of $120 million for severance and exit costs, of which $102 million and $18 million is recorded in accounts payable and accrued expenses and payroll and benefits payable, respectively, on the Condensed Consolidated Balance Sheet. $1 million of these charges were incurred during the first quarter 2023. No payments for these charges have been made as of March 31, 2023.

6. Revenue

Revenue is generated primarily from contracts to produce, ship and deliver steel products, and to a lesser extent, raw materials sales such as iron ore pellets and coke by-products and real estate sales. Generally, U. S. Steel’s performance obligations are satisfied and revenue is recognized when title transfers to our customer for product shipped or services are provided. Revenues are recorded net of any sales incentives. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Costs related to obtaining sales contracts are incidental and are expensed when incurred. Because customers are invoiced at the time title transfers and U. S. Steel’s right to consideration is unconditional at that time, U. S. Steel does not maintain contract asset balances. Additionally, U. S. Steel does not maintain contract liability balances, as performance obligations are satisfied prior to customer payment for product. U. S. Steel offers industry standard payment terms.

The following tables disaggregate our revenue by product for each of the reportable business segments for the three months ended March 31, 2023 and 2022, respectively:

Net Sales by Product (In millions):

11. Stock-Based Compensation Plans

U. S. Steel has outstanding stock-based compensation awards that were granted by the Compensation & Organization Committee (the Committee) of the Board of Directors, or its designee, under the 2005 Stock Incentive Plan (the 2005 Plan) and the 2016 Omnibus Incentive Compensation Plan, as amended and restated (the Omnibus Plan). On April 26, 2016, the Company's stockholders approved the Omnibus Plan and, between 2016 and the present, authorized the Company to issue up to 32,700,000 shares in the aggregate of U. S. Steel common stock under the Omnibus Plan. While the awards that were previously granted under the 2005 Plan remain outstanding, all future awards will be granted under the Omnibus Plan. As of March 31, 2023, there were 6,188,771 shares available for future grants under the Omnibus Plan.

Recent grants of stock-based compensation consist of restricted stock units, total stockholder return (TSR) performance awards and return on capital employed (ROCE) performance awards. Shares of common stock under the Omnibus Plan are issued from authorized, but unissued stock. The following table is a summary of the awards made under the Omnibus Plan during the first three months of 2023 and 2022.


	2023			2022
Grant Details	Shares(a)	Fair Value(b)		Shares(a)	Fair Value(b)

Restricted Stock Units	1,274,520	$	29.90	1,169,470	$	24.27
Performance Awards (c)
TSR	185,120	$	37.41	225,030	$	28.53
ROCE (d)	357,020	$	29.35	396,280	$	23.60

(a) The share amounts shown in this table do not reflect an adjustment for estimated forfeitures.

(b) Represents the per share weighted average for all grants during the period.

(d) A portion of ROCE awards granted in 2023 and 2022 are not shown in the table because they were granted in cash.

U. S. Steel recognized pretax stock-based compensation expense in the amount of $11 million and $16 million in the three-month periods ended March 31, 2023 and 2022, respectively.

As of March 31, 2023, total future compensation expense related to nonvested stock-based compensation arrangements was $79 million, and the weighted average period over which this expense is expected to be recognized is approximately 26 months.

Stock Options

There have been no stock options granted since 2017 other than the 171,000 performance-based stock options granted in December 2021, which are further described below.

The 171,000 performance-based stock options granted in December 2021, which were valued using a lattice model, do not become vested and exercisable until the Company's 20-trading day average closing stock price meets or exceeds the following stock price hurdles during the seven-year period beginning on the grant date, as follows:


20-trading day Average Closing Stock Price Achievement During 7-Year Period Beginning on Grant Date(a)		Percentage of Performance-Based Stock Options Exercisable
$	35.00	33.33	%
$	45.00	33.33	%
$	55.00	33.34	%

(a) The $35.00 tranche vested in April 2022.

Stock Awards

Restricted stock units awarded as part of annual grants generally vest ratably over three years. Their fair value is the average market price of the underlying common stock on the date of grant. Restricted stock units granted in connection with new-hire or retention grants generally cliff vest three years from the date of the grant.

TSR performance awards may vest at varying levels at the end of a three-year performance period if U. S. Steel’s total shareholder return compared to the total shareholder return of a peer group of companies meets performance criteria during the three-year performance period. TSR is calculated as follows: 20 percent for each year in the three-year performance period and 40 percent for the full three-year period. TSR performance awards may vest and payout 50 percent at the threshold level, 100 percent at the target level and 200 percent at the maximum level for payouts. Payment for performance in between the threshold percentages will be interpolated. The fair value of the performance awards is calculated using a Monte-Carlo simulation.

-10-

ROCE performance awards may vest at the end of a three-year performance period contingent upon meeting ROCE performance goals approved by the Committee. For the 2022 and 2023 ROCE performance awards, each year in the three-year performance period is weighted at 20 percent and the full three-year period is weighted at 40 percent of the total award. ROCE performance awards may vest and payout 50 percent at the threshold level, 100 percent at the target level and 200 percent at the maximum level for payouts. Payment for performance in between the threshold percentages will be interpolated. The fair value of the ROCE performance awards is the average market price of the underlying common stock on the date of grant.

In December 2021 and August 2022, special performance-based restricted stock unit awards (PSUs) were granted to members of the Company’s executive leadership team. Shares are earned based on the achievement of certain pre-set quantitative performance criteria during the four-year performance period, January 1, 2022 through December 31, 2025. Shares may vest following the expiration of the Performance Period if the Company satisfies the performance criteria.

The Chief Executive Officer was granted PSUs that vest with the following, equally weighted, performance metrics: (i) EBITDA margin expansion, (ii) greenhouse gas emissions intensity reduction, (iii) asset portfolio optimization, (iv) leverage metrics and (v) corporate relative valuation. Other members of the executive leadership team were granted PSUs that vest with performance criteria related to: (i) on time and on budget completion of BR2 (30% of the grant), (ii) EBITDA margin expansion (40% of the grant) and (iii) greenhouse gas emissions intensity reduction (30% of the grant).

For the PSU awards, a payout is achievable at threshold (50% of target), target (100% of target) or maximum (200% of target) performance achievement. Payout amounts will be interpolated between the threshold, target and maximum amounts.

12. Income Taxes

Tax provision

For the three months ended March 31, 2023, and 2022, the Company recorded a tax provision of $51 million and $246 million, respectively. The tax provisions for the first three months of 2023 and 2022 were based on an estimated annual effective rate, which requires management to make its best estimate of annual pretax income or loss and discrete items recognized during the period, if applicable.

Throughout the year, management regularly updates forecasted annual pretax results for the various countries in which we operate based on changes in factors such as prices, shipments, product mix, plant operating performance and cost estimates. To the extent that actual 2023 pretax results for U.S. and foreign income or loss vary from estimates applied herein, the actual tax provision or benefit recognized in 2023 could be materially different from the forecasted amount used to estimate the tax provision for the three months ended March 31, 2023.

In March 2022, the Company and the Arkansas Economic Development Commission entered into the Recycling Tax Credit Incentive Agreement, whereby the Company may earn state income tax credits in an amount equal to 30 percent of the cost of waste reduction, reuse, or recycling equipment, subject to meeting the requirements of the Arkansas Code Ann. Section 26-51-506, for BR2 which is under construction in Osceola, Arkansas. Documentation supporting the Company's investment in qualifying equipment must be submitted as part of an application for certification expected to be completed on or before 2025. In March 2022, the Company received a lump-sum payment of approximately $82 million as proceeds from the sale of a portion of expected future tax credits to be earned by the Company (see Note 21 for additional information). The Company estimates that it could earn tax credits in excess of $700 million, exclusive of the amount sold in March 2022, which the Company will recognize in the year the assets are placed into service and meet the requirements of Arkansas Code Ann. Section 26-51-506. Any unused tax credit that cannot be claimed in a tax year may be carried forward indefinitely by the Company and applied to its future state tax liability.

On August 16, 2022, H.R. 5376 (commonly called the Inflation Reduction Act of 2022) was signed into law, which, among other things, implemented a corporate alternative minimum tax (CAMT) of 15 percent on net book income of certain large corporations adjusted for certain items prescribed by the legislation. The tax provision for the three months ended March 31, 2023 reflects the impact of CAMT, which is not material to the Condensed Consolidated Financial Statements.

13. Earnings and Dividends Per Common Share

Earnings Per Share Attributable to United States Steel Corporation Stockholders

The effect of dilutive securities on weighted average common shares outstanding included in the calculation of diluted earnings per common share for the three months ended March 31, 2023 and March 31, 2022 were as follows.

-11-


	Three Months Ended March 31,
(Dollars in millions, except per share amounts)	2023		2022
Earnings attributable to United States Steel Corporation stockholders:
Basic	$	199	$	882
Interest expense on Senior Convertible Notes, net of tax	3		3
Diluted	$	202	$	885
Weighted-average shares outstanding (in thousands):
Basic	227,332		261,453
Effect of Senior Convertible Notes	26,194		26,194
Effect of stock options, restricted stock units and performance awards	3,921		5,620
Diluted	257,447		293,267
Earnings per share attributable to United States Steel Corporation stockholders:
Basic	$	0.87	$	3.37
Diluted	$	0.78	$	3.02

Excluded from the computation of diluted earnings per common share due to their anti-dilutive effect were 0.9 million and 0.6 million outstanding securities granted under the Omnibus Plan for the three months ended March 31, 2023 and 2022, respectively.

The dividend for each of the first quarter of 2023 and 2022 was five cents per common share, respectively.

14. Derivative Instruments

U. S. Steel uses foreign exchange forward sales contracts (foreign exchange forwards) with maturities up to 20 months to manage our currency requirements and exposure to foreign currency exchange rate fluctuations. The USSE and Flat-Rolled segments use hedge accounting for their foreign exchange forwards. The Mini Mill segment has foreign exchange forwards for which hedge accounting has not been elected; therefore, the changes in the fair value of their foreign exchange forwards are recognized immediately in the Consolidated Statements of Operations (mark-to-market accounting).

U. S. Steel also uses financial swaps to protect from the commodity price risk associated with purchases of natural gas, zinc, tin, electricity and iron ore (commodity purchase swaps). We elected cash flow hedge accounting for commodity purchase swaps for natural gas, zinc and tin and iron ore and use mark-to-market accounting for electricity swaps. The commodity purchase swaps where hedge accounting was elected have maturities up to 21 months. The commodity purchase swaps where hedge accounting was not elected have maturities of up to 9 months.

U. S. Steel has entered into financial swaps that are used to partially manage the sales price risk of certain hot-rolled coil sales (sales swaps) and iron ore sales (zero cost collars and swaps). Both the sales swaps and the zero cost collars are accounted for using hedge accounting and have maturities of up to 12 months.

The table below shows the outstanding swap quantities used to hedge forecasted purchases and sales as of March 31, 2023 and March 31, 2022:


Hedge Contracts	Classification	March 31, 2023		March 31, 2022
Natural gas (in mmbtus)	Commodity purchase swaps	32,976,000		43,265,000
Tin (in metric tons)	Commodity purchase swaps	1,045		2,430
Zinc (in metric tons)	Commodity purchase swaps	23,783		15,679
Electricity (in megawatt hours)	Commodity purchase swaps	367,200		724,320
Iron ore (in metric tons)	Commodity purchase swaps	280,000		30,000
Iron ore (in metric tons)	Zero-cost collars	—		1,080,000
Iron ore (in metric tons)	Sales swaps	1,087,500		—
Hot-rolled coils (in tons)	Sales swaps	215,000		110,000
Foreign currency (in millions of euros)	Foreign exchange forwards	€	383	€	311
Foreign currency (in millions of dollars)	Foreign exchange forwards	$	85	$	158

The following summarizes the fair value amounts included in our Condensed Consolidated Balance Sheets as of March 31, 2023, and December 31, 2022:

-12-


Balance Sheet Location (in millions)	March 31, 2023		December 31, 2022

Accounts payable	133		68

Other long-term liabilities	4		15
Not Designated as Hedging Instruments
Accounts receivable	4		13
Investments and long-term receivables	—		1

The table below summarizes the effect of hedge accounting on Accumulated Other Comprehensive Income (AOCI) and amounts reclassified from AOCI into earnings for the three months ended March 31, 2023 and 2022:


	Gain (Loss) on Derivatives in AOCI					Amount of Gain (Loss) Recognized in Income
(In millions)	Three Months Ended March 31, 2023		Three Months Ended March 31, 2022		Location of Reclassification from AOCI (a)	Three Months Ended March 31, 2023		Three Months Ended March 31, 2022
Sales swaps	$	(31)	$	(57)	Net sales	$	3	$	(26)
Commodity purchase swaps	(18)		88		Cost of sales (b)	(9)		22
Foreign exchange forwards	(8)		(2)		Cost of sales	4		8
(a) The earnings impact of our hedging instruments substantially offsets the earnings impact of the related hedged items resulting in immaterial ineffectiveness.
(b) Costs for commodity purchase swaps are recognized in cost of sales as products are sold.

At current contract values, $79 million currently in AOCI as of March 31, 2023, will be recognized as an increase in cost of sales over the next year and $37 million currently in AOCI as of March 31, 2023, will be recognized as a decrease in net sales over the next year.

The loss recognized for foreign exchange forwards and financial swaps where hedge accounting was not elected was $10 million for the three months ended March 31, 2023. The loss recognized for sales swaps where hedge accounting was not elected was $9 million for the three months ended March 31, 2022.

Arkansas Development Finance Authority Environmental Improvement Revenue Bonds, Series 2022 (United States Steel Corporation Project) (Green Bonds)

On September 6, 2022, U. S. Steel closed on an offering of $290 million aggregate principal amount of 5.450% Environmental Improvement Revenue Bonds due 2052 (2052 ADFA Green Bonds). U. S. Steel received net proceeds of approximately $287 million after fees of approximately $3 million related to the underwriting and third-party expenses. The net proceeds from the issuance of the 2052 ADFA Green Bonds were used to partially fund work related to U. S. Steel’s solid waste disposal facilities, including two electric arc furnaces (EAF) and other equipment facilities at its new technologically-advanced flat rolled steel making facility, BR2, currently under construction near Osceola, Arkansas.

On and after September 1, 2025, the Company may redeem the 2052 ADFA Green Bonds at its option, at any time in whole or from time to time in part at the redemption prices (expressed in percentages of principal amount) listed below, plus accrued and unpaid interest on the 2052 ADFA Green Bonds, if any, to, but excluding, the applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of each of the years indicated below.


Year	Redemption Price
2025	105.000	%
2026	104.000	%
2027	103.000	%
2028	102.000	%
2029	101.000	%
2030 and thereafter	100.000	%

At any time prior to September 1, 2025, U. S. Steel may also redeem the 2052 ADFA Green Bonds, at our option, in whole or in part, or from time to time, at a price equal to the greater of 100 percent of the principal amount of the 2052 ADFA Green Bonds plus accrued and unpaid interest, if any, or the sum of the present value of the redemption price of the 2052 ADFA Green Bonds if they were redeemed on September 1, 2025, plus interest payments due through September 1, 2025, discounted to the date of redemption on a semi-annual basis at the applicable tax-exempt municipal bond rate, plus accrued and unpaid interest, if any.

2026 Senior Convertible Notes

In October 2019, U. S. Steel issued $350 million of 5.00% Senior Convertible Notes due November 1, 2026 (2026 Senior Convertible Notes). Interest on the 2026 Senior Convertible Notes is payable semi-annually on May 1 and November 1 of each year. The initial conversion rate for the 2026 Senior Convertible Notes is 74.8391 shares of U. S. Steel common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $13.36 per share of common stock, subject to adjustment pursuant to the 2026 Senior Convertible Notes indenture. Based on the initial conversion rate, the 2026 Senior Convertible Notes are convertible into 26,193,685 shares of U. S. Steel common stock and we reserved for the possible issuance of 33,396,930 shares, which is the maximum amount that could be issued upon conversion at maturity. Prior to August 1, 2026, holders of notes may convert all or a portion of their notes at their option only upon the satisfaction of specified conditions and during certain periods. On or after August 1, 2026, holders may convert all or a portion of their notes prior to the maturity date. Upon conversion, we will satisfy the obligation with cash, common stock, or a combination thereof, at our election. U. S. Steel may not redeem the 2026 Senior Convertible Notes prior to November 5, 2023. On or after November 5, 2023, and prior to August 1, 2026, if the price per share of U. S. Steel's common stock has been at least 130% of the conversion price for specified periods, U. S. Steel may redeem all or a portion of the 2026 Senior Convertible Notes at a cash redemption price of 100% of the principal amount, plus accrued and unpaid interest.

If U. S. Steel undergoes a fundamental change, as defined in the 2026 Senior Convertible Notes, holders may require us to repurchase the 2026 Senior Convertible Notes in whole or in part for cash at a price equal to 100% of the principal amount of the 2026 Senior Convertible Notes to be purchased plus any accrued and unpaid interest up to, but excluding the repurchase date.

Big River Steel - Sustainability Linked ABL Facility

Big River Steel's amended senior secured asset-based revolving credit facility (Big River Steel ABL Facility) matures on July 23, 2026. The facility is secured by first-priority liens on accounts receivable and inventory and certain other assets and second priority liens on most tangible and intangible assets of Big River Steel in each case subject to permitted liens. Additionally, the amendment includes sustainability targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™.

The Big River Steel ABL Facility provides for borrowings for working capital and general corporate purposes in an amount equal up to the lesser of (a) $350 million and (b) a borrowing base calculated based on specified percentages of eligible accounts receivables and inventory, subject to certain adjustments and reserves.

Big River Steel LLC must maintain a fixed charge coverage ratio of at least 1.00 to 1.00 for the most recent twelve consecutive months when availability under the Big River Steel ABL Facility is less than the greater of ten percent of the borrowing base availability and $13 million. Based on the most recent four quarters as of March 31, 2023, Big River Steel would have met the fixed charge coverage ratio test. The facility includes affirmative and negative covenants and events of default that are customary for facilities of this type.

There were no loans outstanding under the Big River Steel ABL Facility at March 31, 2023.

U. S. Steel - Sustainability Linked Credit Facility Agreement

On May 27, 2022, U. S. Steel entered into the Sixth Amended and Restated Credit Facility Agreement (Credit Facility Agreement) to replace the existing Fifth Amended and Restated Credit Facility Agreement (Fifth Credit Facility Agreement). The Credit Facility Agreement has substantially the same terms as the Fifth Credit Facility Agreement, except the Credit Facility Agreement references the Secured Overnight Financing Rate instead of the London Interbank Offered Rate, adjusts the individual lenders' commitments, and renews the five-year maturity to May 27, 2027. The Credit Facility Agreement also adjusts the threshold for the fixed charge coverage ratio. The total availability under the facility remained the same at $1,750 million, and the financial impact from replacing the Fifth Credit Facility Agreement was immaterial. Consistent with the Fifth Credit Facility Agreement, the Credit Facility Agreement is secured by first-priority liens on certain accounts receivable and inventory and includes targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™.

The Credit Facility Agreement provides for borrowings for working capital and general corporate purchases in an amount equal to the lesser of (a) $1,750 million or (b) a borrowing base calculated based on specified percentages of eligible accounts receivable and inventory, subject to certain adjustments and reserves. As of March 31, 2023, there were approximately $4 million of letters of credit issued and no loans drawn under the Credit Facility Agreement. U. S. Steel must maintain a fixed charge coverage ratio of at least 1.00 to 1.00 for the most recent four consecutive quarters when availability under the Credit Facility Agreement is less than the greater of ten percent of the maximum facility availability and $140 million. Based on the most recent four quarters as of March 31, 2023, the Company would have met the fixed charge coverage ratio test.

U. S. Steel Košice (USSK) Credit Facilities

On September 29, 2021, USSK entered into a €300 million (approximately $326 million) unsecured sustainability linked credit agreement (USSK Credit Agreement). The USSK Credit Agreement matures in 2026 and contains sustainability targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™. At March 31, 2023, USSK had no borrowings under the USSK Credit Agreement.

-15-

Under the USSK Credit Agreement, USSK is required to maintain a net debt to EBITDA ratio of less than 3.50:1.00 for the rolling twelve months ending June 30, 2023. The Company has determined that it may not be able to comply with the EBITDA ratio covenant at June 30, 2023, based on the currently forecasted EBITDA for the twelve-month period ending June 30, 2023. This could partially or fully limit USSK’s ability to borrow under the USSK Credit Agreement.

Any amendment or waiver may lead to additional lender protections, including a reduction of loan commitments or less favorable terms, and there can be no assurance that USSK can obtain waivers or amendments in timely fashion, or on acceptable terms or at all. The Company believes that USSK will have adequate cash on hand as of June 30, 2023 and will not need to borrow under the USSK Credit Agreement.

During the first quarter of 2023, USSK increased the size of its €20 million credit facility to €30 million (approximately $33 million) (the USSK Credit Facility). At March 31, 2023, USSK had no borrowings under the USSK Credit Facility, and the availability was approximately $16 million due to approximately $17 million of customs and other guarantees outstanding.

16. Fair Value of Financial Instruments

The carrying value of cash and cash equivalents, current accounts and notes receivable, accounts payable and accrued interest included in the Condensed Consolidated Balance Sheet approximate fair value. See Note 14 for disclosure of U. S. Steel’s derivative instruments, which are accounted for at fair value on a recurring basis.

Stelco Option for Minntac Mine Interest

On April 30, 2020 (Effective Date), the Company entered into an Option Agreement with Stelco, Inc. (Stelco), that grants Stelco the option to purchase a 25 percent interest (Option Interest) in a to-be-formed entity (Joint Venture) that will own the Company’s current iron ore mine located in Mt. Iron, Minnesota (Minntac Mine). As consideration for the Option Interest, Stelco paid the Company an aggregate amount of $100 million in five $20 million installments during the year-ended December 31, 2020 which are recorded net of transaction costs in noncontrolling interests in the Condensed Consolidated Balance Sheet. The option can be exercised any time before January 31, 2027, and in the event Stelco exercises the option, Stelco will contribute an additional $500 million to the Joint Venture, which amount shall be remitted solely to U. S. Steel in the form of a one-time special distribution, and the parties will engage in good faith negotiations to finalize the master agreement (pursuant to which Stelco will acquire the Option Interest) and the limited liability company agreement of the Joint Venture.

Surplus VEBA assets

During the fourth quarter 2022, U. S. Steel and the United Steelworkers (USW) agreed to utilize the overfunded OPEB plans to support the benefits provided to active represented employees. Beginning January 1, 2023, this agreement allows the Company to use a certain amount of surplus VEBA assets (the surplus amount) to pay for legally permissible benefits under Section 501(c)(9) of the Internal Revenue Code for active employees and retirees of the USW. The surplus amount of $595 million was determined as of December 31, 2022 and was the balance of VEBA assets in excess of 135% of the retiree obligation at that time. On January 1, 2023, a subaccount was created and consisted of a pro-rata share of the existing trust. On February 1, 2023, using January 31, 2023 asset values, a new investment strategy was implemented and comprised of existing investments from the VEBA trust and cash. On February 1, 2023, certain assets were transferred from the VEBA to the subaccount. The Company is permitted to withdraw a target of $75 million annually, with a guaranteed annual minimum of $50 million, on a quarterly pro rata basis, from the subaccount to cover the cost of the permissible benefits for active USW employees and USW retirees. The surplus VEBA assets subaccount portfolio consists of fixed income securities including corporate bonds, U.S. government bonds, and U.S. Treasury notes, in addition to alternatives including investments in private credit partnerships and real estate funds. A portion of the corporate bonds are classified as available-for-sale debt securities, with unrealized gains and losses reported in Accumulated other comprehensive loss. Upon sale, realized gains and losses are reported in earnings. All other investments in the subaccount are financial instruments measured at fair value or net asset value, with gains and losses recognized through net earnings and are reported as a component of Other financial costs (benefits) on the Company's Consolidated Statements of Operations.

As of March 31, 2023, the fair value of the surplus VEBA assets subaccount portfolio was $602 million, with $75 million in Other current assets and $527 million in Other noncurrent assets on the Condensed Consolidated Balance Sheet. As of March 31, 2023, the value of the investment in corporate bonds classified as available-for-sale debt securities was $252 million. During the three months ended March 31, 2023, pretax net gains of $22 million and $4 million were recognized in Other financial costs (benefits) and in Accumulated other comprehensive loss, respectively.

19. Transactions with Related Parties

Related party sales and service transactions are primarily related to equity investees and were $558 million and $391 million for the three months ended March 31, 2023 and 2022, respectively.

Accounts payable to related parties include balances due to PRO-TEC Coating Company, LLC (PRO-TEC) of $168 million and $142 million at March 31, 2023 and December 31, 2022, respectively for invoicing and receivables collection services provided by U. S. Steel on PRO-TEC's behalf. U. S. Steel, as PRO-TEC’s exclusive sales agent, is responsible for credit risk related to those receivables. U. S. Steel also provides PRO-TEC marketing, selling and customer service functions. Payables to other related parties totaled $3 million and $1 million for the periods ending March 31, 2023 and December 31, 2022, respectively.

Purchases from related parties for outside processing services provided by equity investees amounted to $7 million for both periods ending March 31, 2023 and 2022, respectively. Purchases of iron ore pellets from related parties amounted to $21 million and $25 million for the three months ended March 31, 2023 and 2022, respectively.

20. Restructuring and Other Charges

During the three months ended March 31, 2023, the Company recorded restructuring and other charges of $1 million, which related to the planned disposition of a component within the Flat-Rolled segment. Cash payments were made related to previously accrued restructuring programs of approximately $46 million.

-19-

During the three months ended March 31, 2022, the Company recorded restructuring and other charges of $17 million related to the planned sale of a component within the Flat-Rolled segment. Cash payments were made related to previously accrued restructuring programs of approximately $23 million.

The activity in the accrued balances incurred in relation to restructuring during the three months ended March 31, 2023, was as follows:


(In millions)	Employee Related Costs		Exit Costs		Non-cash Charges		Total

21. Contingencies and Commitments

U. S. Steel is the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Condensed Consolidated Financial Statements. However, management believes that U. S. Steel will remain a viable and competitive enterprise even though it is possible that these contingencies could be resolved unfavorably.

U. S. Steel accrues for estimated costs related to existing lawsuits, claims and proceedings when it is probable that it will incur these costs in the future and the costs are reasonably estimable.

Asbestos matters – As of March 31, 2023, U. S. Steel was a defendant in approximately 920 active asbestos cases involving approximately 2,510 plaintiffs. The vast majority of these cases involve multiple defendants. About 1,545, or approximately 62 percent, of these plaintiff claims are currently pending in a jurisdiction which permits filings with massive numbers of plaintiffs. At December 31, 2022, U. S. Steel was a defendant in approximately 920 active asbestos cases involving approximately 2,510 plaintiffs. Based upon U. S. Steel’s experience in such cases, it believes that the actual number of plaintiffs who ultimately assert claims against U. S. Steel will likely be a small fraction of the total number of plaintiffs.

-20-

The following table shows the number of asbestos claims in the current period and the prior three years:


Period ended	Opening Number of Claims	Claims Dismissed, Settled and Resolved	New Claims	Closing Number of Claims
December 31, 2020	2,390	240	295	2,445
December 31, 2021	2,445	200	260	2,505
December 31, 2022	2,505	230	235	2,510
March 31, 2023	2,510	50	50	2,510

The amount U. S. Steel accrues for pending asbestos claims is not material to U. S. Steel’s financial condition. However, U. S. Steel is unable to estimate the ultimate outcome of asbestos-related claims due to a number of uncertainties, including: (1) the rates at which new claims are filed, (2) the number of and effect of bankruptcies of other companies traditionally defending asbestos claims, (3) uncertainties associated with the variations in the litigation process from jurisdiction to jurisdiction, (4) uncertainties regarding the facts, circumstances and disease process with each claim and (5) any new legislation enacted to address asbestos-related claims.

Further, U. S. Steel does not believe that an accrual for unasserted claims is required. At any given reporting date, it is probable that there are unasserted claims that will be filed against the Company in the future. The Company engages an outside valuation consultant to assist in assessing its ability to estimate an accrual for unasserted claims. This assessment is based on the Company's settlement experience, including recent claims trends. The analysis focuses on settlements made over the last several years as these claims are likely to best represent future claim characteristics. After review by the valuation consultant and U. S. Steel management, it was determined that the Company could not estimate an accrual for unasserted claims.

Despite these uncertainties, management believes that the ultimate resolution of these matters will not have a material adverse effect on U. S. Steel’s financial condition.

Environmental matters – U. S. Steel is subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance. Changes in accrued liabilities for remediation activities where U. S. Steel is identified as a named party are summarized in the following table:


(In millions)	Three Months Ended March 31, 2023
Beginning of period	$	126
Accruals for environmental remediation deemed probable and reasonably estimable	—
Obligations settled	(6)
End of period	$	120

Accrued liabilities for remediation activities are included in the following Condensed Consolidated Balance Sheet lines:


	As of		As of
(In millions)	March 31, 2023		December 31, 2022
Accounts payable	$	32	$	32
Deferred credits and other noncurrent liabilities	88		94
Total	$	120	$	126

Expenses related to remediation are recorded in cost of sales and were $1 million for the three months ended March 31, 2023. Expenses for the three months ended March 31, 2022, were immaterial. It is not currently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties that may be imposed. Due to uncertainties inherent in remediation projects and the associated liabilities, it is reasonably possible that total remediation costs for active matters may exceed the accrued liabilities by as much as 20 to 35 percent.

Remediation Projects

U. S. Steel is involved in environmental remediation projects at or adjacent to several current and former U. S. Steel facilities and other locations that are in various stages of completion ranging from initial characterization through post-closure monitoring. Based on the anticipated scope and degree of uncertainty of projects, the Company categorizes projects as follows:

-21-

(1)Projects with Ongoing Study and Scope Development - For these projects, the extent of remediation that may be required is not yet known, the remediation methods and plans are not yet developed, and/or cost estimates cannot be determined. Therefore, significant costs, in addition to the accrued liabilities for these projects, are reasonably possible. There are four environmental remediation projects where additional costs for completion are not currently estimable but could be material. These projects are at Fairfield Works, Lorain Tubular, UPI and the former steelmaking plant at Joliet, Illinois. As of March 31, 2023, accrued liabilities for these projects totaled $1 million for the costs of studies, investigations, interim measures, design and/or remediation. It is reasonably possible that additional liabilities associated with future requirements regarding studies, investigations, design and remediation for these projects could be as much as $22 million to $36 million.

(2)Projects with Significant Accrued liabilities with a Defined Scope - As of March 31, 2023, there are three significant projects with defined scope greater than or equal to $5 million each, with a total accrued liability of $64 million. These projects are Gary Resource Conservation and Recovery Act (accrued liability of $26 million), Duluth Works (accrued liability of $20 million) and the former Geneva facility (accrued liability of $18 million).

(3)Other Projects with a Defined Scope - These projects involve relatively small accrued liabilities for which we believe that, while additional costs are possible, they are not likely to be significant, and also include those projects for which we do not yet possess sufficient information to estimate potential costs to U. S. Steel. There are two other environmental remediation projects which each had an accrued liability of between $1 million and $5 million. The total accrued liability for these projects at March 31, 2023, was $3 million. These projects have progressed through a significant portion of the design phase and material additional costs are not expected.

The remaining environmental remediation projects each have an accrued liability of less than $1 million each. The total accrued liability for these projects at March 31, 2023, was approximately $6 million. The Company does not foresee material additional liabilities for any of these sites.

Post-Closure Costs – Accrued liabilities for post-closure site monitoring and other costs at various closed landfills totaled $23 million at March 31, 2023 and were based on known scopes of work.

Administrative and Legal Costs – As of March 31, 2023, U. S. Steel had an accrued liability of $11 million for administrative and legal costs related to environmental remediation projects. These accrued liabilities were based on projected administrative and legal costs for the next three years and do not change significantly from year to year.

Capital Expenditures – For a number of years, U. S. Steel has made substantial capital expenditures to comply with various regulations, laws and other requirements relating to the environment. Such capital expenditures totaled $11 million and $5 million in the first three months of 2023 and 2022, respectively. U. S. Steel anticipates making additional such expenditures in the future, which may be material; however, the exact amounts and timing of such expenditures are uncertain because of the continuing evolution of specific regulatory requirements.

European Union (the EU) Environmental Requirements - Phase IV of the EU Emissions Trading System (the EU ETS) commenced on January 1, 2021 and will finish on December 31, 2030. The European Commission issued final approval of the updated 2021-2025 Slovak National Allocation table in February 2022. The Slovak Ministry of Environment has not yet allocated 2023 emission credits that it grants at no charge (free allowances) to the USSE account. As of March 31, 2023, we have pre-purchased approximately 1.35 million European Union Emission Allowances (EUA) totaling €107 million (approximately $116 million) to cover the expected 2023 shortfall of emission allowances.

The EU’s Industrial Emissions Directive requires implementation of EU-determined best available techniques (BAT) for Iron and Steel production to reduce environmental impacts as well as compliance with BAT associated emission levels. Total capital expenditures for projects to comply with or go beyond BAT requirements were €138 million (approximately $150 million) over the actual program period. These costs were partially offset by the EU funding received and may be mitigated over the next measurement periods if USSK complies with certain financial covenants, which are assessed annually. The last assessment of financial covenants will be performed as of June 30, 2026. USSK complied with these covenants as of March 31, 2023. If we are unable to meet these covenants in the future, USSK might be required to provide additional collateral (e.g., bank guarantee) to secure 50 percent of the EU funding received.

Environmental indemnifications – Throughout its history, U. S. Steel has sold numerous properties and businesses and many of these sales included indemnifications and cost sharing agreements related to the assets that were divested. The amount of potential environmental liability associated with these transactions and properties is not estimable due to the nature and extent of the unknown conditions related to the properties divested and deconsolidated. Aside from the environmental liabilities already recorded as a result of these transactions due to specific environmental remediation activities and cases (included in the $120 million of accrued liabilities for remediation discussed above), there are no other known probable and estimable environmental liabilities related to these transactions.

Guarantees – The maximum guarantees of the indebtedness of unconsolidated entities of U. S. Steel totaled $7 million at March 31, 2023.

-22-

Other contingencies – Under certain lease agreements covering various equipment, U. S. Steel has the option to renew the lease or to purchase the equipment at the end of the lease term. If U. S. Steel does not exercise the purchase option by the end of the lease term, U. S. Steel guarantees a residual value of the equipment as determined at the lease inception date (totaling approximately $15 million at March 31, 2023). No liability has been recorded for these guarantees as the potential loss is not probable.

The Company's BR2 project in Osceola, Arkansas qualifies for financing and related economic incentives associated with the acquisition, development, construction, and operation of the facility. These incentives consist of advance lump-sum payments which are included in deferred credits and other noncurrent liabilities on the Condensed Consolidated Balance Sheet. In March 2022, the Company received a lump-sum payment of approximately $82 million as proceeds from the sale of a portion of expected future tax credits to be earned by the Company under the State of Arkansas's Recycling Tax Credit program. These funds are to be used primarily for the acquisition of project related equipment, however they may also be used for the training and development of new employees hired for the project. The Company is contingently liable for certain repayment penalties if the Company fails to meet certain employment requirements in any given period. In April 2022, the Company received a $3 million grant from Mississippi County, Arkansas, and in May 2022, the Company received a $50 million grant from the State of Arkansas Quick Action Closing Fund. Both grants pertain to the reimbursement of qualifying project costs. Deferred liabilities were recognized for each of these grants and are included in deferred credits and other noncurrent liabilities on the Condensed Consolidated Balance Sheet. For each of these incentives and grants, the balance of deferred income will be recognized into other gains, net in the accompanying Condensed Consolidated Statements of Operations on a systematic basis over the periods in which the Company earns the granted funds by complying with the investment and employment requirements of the grant programs.

Insurance – U. S. Steel maintains insurance for certain property damage, equipment, business interruption and general liability exposures; however, insurance is applicable only after certain deductibles and retainages. U. S. Steel is self-insured for certain other exposures including workers’ compensation (where permitted by law) and auto liability. Liabilities are recorded for workers’ compensation and personal injury obligations. Other costs resulting from losses under deductible or retainage amounts or not otherwise covered by insurance are charged against income upon occurrence.

U. S. Steel uses surety bonds, trusts and letters of credit to provide whole or partial financial assurance for certain obligations such as workers’ compensation. The total amount of active surety bonds, trusts and letters of credit being used for financial assurance purposes was approximately $182 million as of March 31, 2023, which reflects U. S. Steel’s maximum exposure under these financial guarantees, but not its total exposure for the underlying obligations. A significant portion of our trust arrangements and letters of credit are collateralized by the Credit Facility Agreement. The remaining trust arrangements and letters of credit are collateralized by restricted cash. Restricted cash, which is recorded in other current and noncurrent assets, totaled $36 million and $35 million at March 31, 2023, and December 31, 2022, respectively.

Capital Commitments – At March 31, 2023, U. S. Steel’s contractual commitments to acquire property, plant and equipment totaled $2.203 billion.

Contractual Purchase Commitments – U. S. Steel is obligated to make payments under contractual purchase commitments, including unconditional purchase obligations. Payments for contracts with remaining terms in excess of one year are summarized below (in millions):


Remainder of 2023	2024	2025	2026	2027	Later Years	Total
$458	$632	$283	$280	$152	$473	$2,278

The majority of U. S. Steel’s unconditional purchase obligations relates to the supply of industrial gases, and certain energy and utility services with terms ranging from 13 months to 13 years. Unconditional purchase obligations also include coke and steam purchase commitments related to a coke supply agreement with Gateway Energy & Coke Company LLC (Gateway) under which Gateway is obligated to supply a minimum volume of the expected targeted annual production of the heat recovery coke plant, and U. S. Steel is obligated to purchase the coke from Gateway at the contract price. As of March 31, 2023, if U. S. Steel were to terminate the agreement, it may be obligated to pay in excess of $70 million.

Total payments relating to unconditional purchase obligations were $275 million and $217 million for the three months ended March 31, 2023 and 2022, respectively.

-23-

22. Common Stock Issued and Repurchased

On October 25, 2021, the Board of Directors authorized a share repurchase program that allowed for the repurchase of up to $300 million of its outstanding common stock from time to time in the open market or privately negotiated transactions. On January 24, 2022 the Board of Directors authorized an additional $500 million under the share repurchase program.

U. S. Steel repurchased 2.8 million and 5.0 million shares of common stock for approximately $75 million and $123 million under these programs during the three months ended March 31, 2023 and 2022, respectively.


Item 2.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

During the three months ended March 31, 2023, the Company noted favorable trends in the commercial environment for all reportable segments. For the North American Flat-Rolled segment, sequential results were lower in the first quarter due in part to the typical seasonal mining headwinds and lower average selling prices. Customer demand and selling prices improved as the quarter progressed. Improved market prices should be more fully reflected in our second quarter results as extended lead times delayed pricing realization in the first quarter. The improving commercial environment led to our decision to restart blast furnace #3 at Mon Valley Works in January and blast furnace #8 at Gary Works in March. The Mini Mill segment benefited from rising spot prices and normalizing raw material costs on a sequential basis to the fourth quarter 2022. For the second quarter, we expect the Mini Mill segment’s average selling price to continue to increase sequentially. The U. S. Steel Europe segment benefited from higher volume and lower raw material costs on a sequential basis to the fourth quarter 2022 partially offset by lower average selling prices. As a result of improving demand in Europe, the Company restarted blast furnace #2 at USSK in January. For the second quarter, we expect results at USSE to improve due to increased realization of higher market prices in the segment’s average selling price compared to the first quarter 2023. The Tubular segment results benefited from continued strong demand and higher pricing on a sequential basis to the fourth quarter 2022. In the second quarter, we expect lower pricing coming off elevated fourth quarter 2022 levels and customer inventory rebalancing to impact segment performance in relation to the first quarter 2023.

The Company continued to advance its Best for All® strategy in the first quarter. Construction of Big River 2 in Osceola, Arkansas continued during the quarter. This new mini mill is expected to have about 3 million tons per year of steelmaking capability and will combine two state-of-the-art EAFs with differentiated steelmaking and finishing technology, including endless casting and rolling equipment and a planned advanced high-strength steel (AHSS) finishing line. This project is on track to be completed in 2024. In addition, construction of a direct reduced (DR) grade pellet facility at the Company’s Keetac ore operations continues, as well as the construction on a 200 thousand ton non-grain oriented (NGO) electrical steel line and a 325 thousand ton galvanize/Galvalume® line, both at Big River Steel. These projects are on-budget and on track for on-time completion. Capital expenditures for strategic projects were $582 million during the three months ended March 31, 2023.

Fluctuations in the market price of raw materials and other inflationary impacts have affected the results of each of our reportable segments, and fluctuations going-forward are reasonably likely to have a material impact on future results. We could experience inflation related headwinds for certain raw materials and other costs.

In February 2022, Russia invaded Ukraine and active conflict continues in the country. The war in Ukraine will likely continue to cause disruption and instability in Russia, Ukraine, as well as the markets in which we operate. The Company is constantly monitoring the situation for impacts and risks to the business and has implemented risk mitigating strategies where possible. As a result of the invasion, governments around the world, including the European Union (EU) and the United States of America (U.S.), have enacted sanctions against Russia and Russian interests. We are complying with all applicable sanctions that impact our business.

Since the onset of the war, and before, USSE has been building its inventory of iron ore and coal and procuring them through alternate sources. With the EU prohibiting purchases of coal from suppliers in Russia, new purchases of coal originating from Russia have stopped. The Company has built up sufficient inventory on site or in-transit to meet current customer demand and alternate supply chains have been fully implemented.

Additionally, Russian supply of natural gas to Europe has decreased significantly in response to enacted sanctions. However, Slovakia has natural gas storage and access to additional supply from countries including Norway, the U.S. and Africa. Together,

these sources are enough to support the country's expected consumption through the first half of 2023, which includes demand for natural gas for our USSE segment operations.

RESULTS OF OPERATIONS

U. S. Steel's results in the three months ended March 31, 2023, compared to the same period in 2022, declined for the North American Flat-Rolled, Mini Mill and U. S. Steel Europe segments, primarily as a result of lower sales pricing. The Company's Tubular Products segment outperformed the prior year period due to higher sales pricing and increased demand.

•North American Flat-Rolled (Flat-Rolled): Flat-Rolled results declined primarily due to lower sales price across many customer and manufacturing industries.

•Mini Mill: Mini Mill results declined primarily due to lower sales price across most consuming industries.

•USSE: USSE results declined primarily due to lower sales volume and price and higher raw material and energy costs.

•Tubular: Tubular results improved primarily due to higher sales price from the steady high levels of drilling activity, partially offset by continued high levels of imports.

Net sales by segment for the three months ended March 31, 2023 and 2022 are set forth in the following table:


	Three Months Ended March 31,
(Dollars in millions, excluding intersegment sales)	2023		2022		% Change
Flat-Rolled	$	2,570	$	2,954	(13)%
Mini Mill	553		718		(23)%
USSE	838		1,251		(33)%
Tubular	505		309		63%
Total sales from reportable segments	4,466		5,232		(15)%
Other	4		2		100%
Net sales	$	4,470	$	5,234	(15)%

Management’s analysis of the percentage change in net sales for U. S. Steel’s reportable business segments for the three months ended March 31, 2023 versus the three months ended March 31, 2022:


	Steel Products (a)
	Volume		Price		Mix		FX (b)		Other (c)		Net Change
Flat-Rolled	15	%	(24)	%	(3)	%	—	%	(1)	%	(13)	%
Mini Mill	29	%	(52)	%	—	%	—	%	—	%	(23)	%
USSE	(20)	%	(9)	%	(1)	%	(4)	%	1	%	(33)	%
Tubular	2	%	60	%	1	%	—	%	—	%	63	%
(a) Excludes intersegment sales.
(b) Foreign currency translation effects.
(c) Primarily sales of raw materials and coke making by-products.

Net sales for the three months ended March 31, 2023 compared to the same period in 2022 were $4,470 million and $5,234 million, respectively.

•For the Flat-Rolled segment, the decrease in sales primarily resulted from lower average realized prices ($356 per ton) across most products, partially offset by increased shipments (331 thousand tons) across most products.

•For the Mini Mill segment, the decrease in sales primarily resulted from lower average realized prices ($578 per ton) across all products, partially offset by increased shipments (152 thousand tons) across all products.

•For the USSE segment, the decrease in sales primarily resulted from lower average realized prices ($200 per ton) across most products and decreased shipments (227 thousand tons) across most products.

•For the Tubular segment, the increase in sales primarily resulted from higher average realized prices ($1,408 per ton) and increased shipments (3 thousand tons).

Selling, general and administrative expenses

-25-

Selling, general and administrative expenses were $99 million in the three months ended March 31, 2023 compared to $117 million in the three months ended March 31, 2022. The change in period over period expenses was primarily driven by profit and variable based incentive costs.

Restructuring and other charges

During the three months ended March 31, 2023, the Company recognized restructuring and other charges of $1 million compared to charges of $17 million recognized during the three months ended March 31, 2022. The charges recognized in the current and the prior year period pertain to the planned disposition of certain assets related to a component of the Company's flat-rolled business. See Note 20 to the Condensed Consolidated Financial Statements for further details.

Operating configuration adjustments

The Company adjusts its operating configuration in response to changes in market conditions, global overcapacity, unfair trade practices, and changes in customer demand. These operating configuration adjustments can include indefinitely and temporarily idling certain of its facilities as well as re-starting production at certain of its facilities. The Company will continue to adjust its operating configuration in order to ensure its order book and production footprint are balanced.

Idled Operations

The following operations were initially idled in 2020 and remained idle as of March 31, 2023. These facilities and their respective carrying values as of March 31, 2023 included:

•Blast furnace A at Granite City Works, $55 million

•Lone Star Tubular Operations, $5 million

•Lorain Tubular Operations, $60 million

•Wheeling Machine Products coupling production facility at Hughes Springs, Texas, immaterial

In 2022, U. S. Steel indefinitely idled the majority of the tin mill operations at Gary Works. This included the Tin Line #5 and the Tin Line #6. As of March 31, 2023, the carrying value of the indefinitely idled tin mill operations assets at Gary Works is $80 million.

In the first quarter of 2023, the Company completed the previously announced permanent shutdown of coke batteries numbers 1 through 3 at the Mon Valley Works.

(Dollars in millions)	2023		2022
Interest expense	$	27	$	50	46	%
Interest income	(30)		(1)		2,900	%

Net interest and other financial benefits improved in the three months ended March 31, 2023, as compared to the same period in 2022 primarily due to increased interest income on cash deposits, lower interest expense as a result of increased capitalized interest, and gains on the investments in the surplus VEBA subaccount portfolio, partially offset by reduced net periodic benefit income due to 2022 plan asset performance, the transfer of $595 million in surplus VEBA funds, and increased prior service cost.

Income taxes

Income tax expense was $51 million and $246 million for the three months ended March 31, 2023 and March 31, 2022, respectively. The change from the prior year period was primarily due to a decrease in earnings before taxes.

Net earnings

Net earnings attributable to United States Steel Corporation were $199 million in the three months ended March 31, 2023 compared to net earnings of $882 million in the three months ended March 31, 2022. The changes primarily reflect the factors discussed above.

LIQUIDITY AND CAPITAL RESOURCES

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $181 million for the three months ended March 31, 2023 compared to net cash provided by operating activities of $771 million in the same period in 2022. The period over period decrease in cash from operations from the prior year period was primarily due to lower net earnings and changes in income taxes payable and deferred taxes, partially offset by changes in working capital. Changes in working capital can vary significantly depending on factors such as the timing of inventory production and purchases, which is affected by the length of our business cycles as well as our captive raw materials position, customer payments of accounts receivable and payments to vendors in the regular course of business.

As shown below our cash conversion cycle for the first quarter of 2023 decreased by 5 days as compared to the fourth quarter of 2022.


Cash Conversion Cycle	First Quarter of 2023		Fourth Quarter of 2022
	$ millions	Days	$ millions	Days
Accounts receivable, net (a)	$1,808	35	$1,634	39

+ Inventories (b)	$2,541	56	$2,359	60

- Accounts Payable and Other Accrued Liabilities (c)	$3,001	67	$2,831	70
= Cash Conversion Cycle (d)		24		29

(a) Calculated as Average Accounts Receivable, net divided by total Net Sales multiplied by the number of days in the period.

(b) Calculated as Average Inventory divided by total Cost of Sales multiplied by the number of days in the period.

(c) Calculated as Average Accounts Payable and Other Accrued Liabilities less bank checks outstanding and other current liabilities divided by total Cost of Sales multiplied by the number of days in the period.

(d) Calculated as Accounts Receivable Days plus Inventory Days less Accounts Payable Days.

The cash conversion cycle is a non-generally accepted accounting principles (non-GAAP) financial measure. We believe the cash conversion cycle is a useful measure in providing investors with information regarding our cash management performance and is a widely accepted measure of working capital management efficiency. The cash conversion cycle should not be considered in isolation or as an alternative to other GAAP metrics as an indicator of performance.

The last-in, first-out (LIFO) inventory method is the predominant method of inventory costing for our Flat-Rolled and Tubular segments. Based on the Company’s latest internal forecasts and its inventory requirements, management does not believe there will be significant permanent LIFO liquidations that would impact earnings for the remainder of 2023.

Net Cash Used in Investing Activities

Net cash used in investing activities was $738 million for the three months ended March 31, 2023 compared to net cash used in investing activities of $352 million in the same period in 2022. The increase in net cash used in investing activities was primarily due to increased capital expenditures (discussed in more detail below).

Capital expenditures for the three months ended March 31, 2023, were $740 million, compared with $349 million in the same period in 2022. Mini Mill capital expenditures were $563 million and included $419 million for BR2, exclusive of the air separation unit, as well as spending for the CGL and the NGO being built at the existing Big River Steel facility. Flat-Rolled capital expenditures were $139 million which includes spending for the construction of a DR grade pellet facility at Keetac as well as mining equipment and other infrastructure, environmental, Gary pig iron facility and other strategic projects across the Flat-Rolled footprint. USSE capital expenditures were $26 million and included spending for the blast furnace, enterprise resource planning (ERP) project, 5-stand control system upgrades and various other projects. Tubular capital expenditures were $12 million and included spending to support steelmaking, infrastructure, and environmental projects within the Tubular footprint.

Net Cash Used in Financing Activities

Net cash used in financing activities was $117 million for the three months ended March 31, 2023 compared to net cash used in financing activities of $71 million in the same period last year. The period over period increase in cash used in financing activities was primarily due to the absence of proceeds from government incentives in the current period, partially offset by decreased repurchases of common stock.

Debt Financing

Certain of our credit facilities, including the Credit Facility Agreement, the Big River Steel ABL Facility, the USSK Credit Agreement and the Export Credit Agreement, contain standard terms and conditions including customary material adverse

-30-

change clauses. If a material adverse change was to occur, our ability to fund future operating and capital requirements could be negatively impacted. The €300 million USSK Credit Agreement contains certain USSK specific financial covenants. There are currently no amounts outstanding under the facility. The USSK Credit Agreement requires USSK to maintain a net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) ratio of less than 3.50:1 for the rolling twelve months ending June 30, 2023. The Company has determined that it may not be able to comply with this covenant at June 30, 2023 based on the currently forecasted EBITDA for the twelve-month period ending June 30, 2023. This could partially or fully limit USSK's ability to borrow under the USSK Credit Agreement. Any amendment or waiver may lead to additional lender protections, including a reduction of loan commitments or less favorable terms, and there can be no assurance that USSK can obtain waivers or amendments in timely fashion, or on acceptable terms or at all. The Company believes that USSK will have adequate cash on hand as of June 30, 2023 and will not need to borrow under the USSK Credit Agreement.

We use surety bonds, trusts and letters of credit to provide financial assurance for certain transactions and business activities. The use of some forms of financial assurance and cash collateral have a negative impact on liquidity. U. S. Steel has committed approximately $182 million of liquidity sources for financial assurance purposes as of March 31, 2023. Changes in certain of these commitments which use collateral are reflected within cash, cash equivalents and restricted cash on the Condensed Consolidated Statement of Cash Flows.

Share Repurchases

On July 25, 2022, following the completion of the previously authorized $800 million share repurchase programs, the Board of Directors authorized a new share repurchase program that allows for the repurchase of up to $500 million of its outstanding common stock from time to time in the open market or privately negotiated transactions at the discretion of management. The Company's share repurchase program does not obligate it to acquire any specific number of shares. Common stock repurchased under our share repurchase programs totaled 2.8 million shares for approximately $75 million in the three months ended March 31, 2023. See Note 22 to the Condensed Consolidated Financial Statements for further details.

Capital Requirements

U. S. Steel’s contractual commitments to acquire property, plant and equipment at March 31, 2023, totaled $2.203 billion.

Liquidity

The following table summarizes U. S. Steel’s liquidity as of March 31, 2023:


(Dollars in millions)
Cash and cash equivalents	$	2,837
Amount available under Credit Facility Agreement	1,746
Amount available under Big River Steel - Revolving Line of Credit	350
Amount available under USSK Credit Agreement and USSK Credit Facility	342
Total estimated liquidity	$	5,275

We finished the first quarter of 2023 with $2,837 million of cash and cash equivalents and $5,275 million of total liquidity. Available cash is left on deposit with financial institutions or invested in highly liquid securities with parties we believe to be creditworthy. Substantially all of the liquidity attributable to our foreign subsidiaries can be accessed without the imposition of income taxes as a result of a prior election to liquidate for U.S. income tax purposes a foreign subsidiary that holds most of our international operations.

We expect that our estimated liquidity requirements will consist primarily of our 2023 planned strategic and sustaining capital expenditures, working capital requirements, interest expense, and operating costs and employee benefits for our operations after taking into account the footprint actions and cost reductions at our plants and headquarters. Our available liquidity at March 31, 2023 consists principally of our cash and cash equivalents and available borrowings under the Credit Facility Agreement, Big River Steel ABL Facility, USSK Credit Agreement and the USSK Credit Facility.

Management continues to evaluate market conditions in our industry and our global liquidity position and may consider additional actions to further strengthen our balance sheet and optimize liquidity, including but not limited to the repayment or refinancing of outstanding debt and the incurrence of additional debt to opportunistically finance strategic projects. The Company may also return excess liquidity to shareholders through share repurchases and dividends from time to time if deemed appropriate by management.

U. S. Steel management believes that our liquidity will be adequate to fund our requirements based on our current assumptions with respect to our results of operations and financial condition.

Environmental Matters, Litigation and Contingencies

Some of U. S. Steel’s facilities were in operation before 1900. Although the Company believes that its environmental practices have either led the industry or at least been consistent with prevailing industry practices, hazardous materials have been and may continue to be released at current or former operating sites or delivered to sites operated by third parties.

Our U.S. facilities are subject to environmental laws applicable in the U.S., including the Clean Air Act (the CAA), the Clean Water Act (CWA), the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), as well as state and local laws and regulations.

U. S. Steel has incurred and will continue to incur substantial capital, operating, and maintenance and remediation expenditures as a result of environmental laws and regulations, related to release of hazardous materials, which in recent years have been mainly for process changes to meet the CAA obligations and similar obligations in Europe.

EU Environmental Requirements and Slovak Operations

Phase IV of the EU Emissions Trading System (the EU ETS) commenced on January 1, 2021 and will finish on December 31, 2030. The European Commission issued final approval of the updated 2021-2025 Slovak National Allocation table in February 2022. The Slovak Ministry of Environment has not yet allocated 2023 emission credits that it grants at no charge (free allowances) to the USSE account. As of March 31, 2023, we have pre-purchased approximately 1.35 million European Union Emission Allowances (EUA) totaling €107 million (approximately $116 million) to cover the expected 2023 shortfall of emission allowances.

The EU’s Industrial Emissions Directive requires implementation of EU determined best available techniques (BAT) for Iron and Steel production to reduce environmental impacts as well as compliance with BAT associated emission levels. Total capital expenditures for projects to comply with or go beyond BAT requirements were €138 million (approximately $150 million). These costs were partially offset by the EU funding received and may be mitigated over the next measurement periods if USSK complies with certain financial covenants, which are assessed annually. The last assessment of financial covenants will be performed as of June 30, 2026. USSK complied with these covenants as of March 31, 2023. If we are unable to meet these covenants in the future, USSK might be required to provide additional collateral (e.g., bank guarantee) to secure 50 percent of the EU funding received.

For further discussion of laws applicable in Slovakia and the EU and their impact on USSE, see Note 21 to the Condensed Consolidated Financial Statements, “Contingencies and Commitments - Environmental Matters, EU Environmental Requirements.”

New and Emerging Environmental Regulations

United States and European Greenhouse Gas Emissions Regulations

The Phase IV EU ETS period spans 2021-2030 and began on January 1, 2021.The Phase IV period is divided into two sub periods (2021-2025 and 2026-2030), rules for the first subperiod are finalized, however we expect that rules for the second subperiod may be more stringent than those for the first one. Once approved, the rules may impact subperiod 2026-2030. Currently, the overall EU ETS target is a 40 percent reduction of 1990 emissions by 2030. Free allocation of CO2 allowances is based on reduced benchmark values which have been published in the first quarter of 2021 and historical levels of production from 2014-2018. Allocations to individual installations may be adjusted annually to reflect relevant increases and decreases in

-32-

production. The threshold for adjustments is set at 15 percent and will be assessed on the basis of a rolling average of two precedent years. Production data verified by an external auditor shows that USSE's rolling average for 2020-2021 returned to the base limit for hot metal production resulting in an increase to the free allocation for 2022 compared to 2021, however the 2022 free allocation was still slightly reduced due to missing the 15 percent threshold for sinter production. Additionally, lower production in 2019 through 2021 will have an impact on the future free allocation for 2026-2030, where the historical production average for years 2019-2023 will be assessed. Based on actual production data for 2022, we expect that the free allocation for hot metal will remain unchanged for 2023, however allocations for sinter will be lower.

In order to achieve the EU political goal of carbon emissions neutrality by 2050, on July 14, 2021, the European Commission released a package of legislative proposals called Fit for 55. The proposals contain significant changes to current EU ETS functions and requirements, including: a new carbon border adjustment mechanism to impose carbon fees on EU imports, further reduction of free CO2 allowance allocation to heavy industry and measures to strengthen the supply of carbon allowances. The legislative process is being impacted by the ongoing Russia-Ukraine crisis. The proposals are subject to the EU legislative process, and we cannot predict their future impact.

United States - Air

The CAA imposes stringent limits on air emissions with a federally mandated operating permit program and civil and criminal enforcement sanctions. The CAA requires, among other things, the regulation of hazardous air pollutants through the development and promulgation of National Emission Standards for Hazardous Air Pollutants (NESHAP) and Maximum Achievable Control Technology (MACT) Standards. The U.S. EPA has developed various industry-specific MACT standards pursuant to this requirement. The CAA requires the U.S. EPA to promulgate regulations establishing emission standards for each category of Hazardous Air Pollutants. The U.S. EPA also must conduct risk assessments on each source category that is already subject to MACT standards and determine if additional standards are needed to reduce residual risks.

While our operations are subject to several different categories of NESHAP and MACT standards, the principal impact of these standards on U. S. Steel's operations includes those that are specific to coke making, iron making, steel making and iron ore processing.

On July 13, 2020, the U.S. EPA published a Residual Risk and Technology Review rule for the Integrated Iron and Steel MACT category in the Federal Register. Based on the results of the U.S. EPA’s risk review, the agency determined that risks due to emissions of air toxics from the Integrated Iron and Steel category are acceptable and that the current regulations provided an ample margin of safety to protect public health. Under the technology review, the U.S. EPA determined that there are no developments in practices, processes or control technologies that necessitate revision of the standards. In September 2020, several petitions for review of the rule, including those filed by the Company, the American Iron and Steel Institute (the AISI), Clean Air Council and others, were filed with the United States Court of Appeals for the D.C. Circuit. The cases were consolidated and are being held in abeyance until the U.S. EPA reviews and responds to administrative petitions for review. The U.S. EPA is required by court order to issue a final rule by October 26, 2023. Because the U.S. EPA has yet to propose a revised iron and steel rule, any impacts are not estimable at this time.

For the Taconite Iron Ore Processing category, based on the results of the U.S. EPA's risk review, the agency promulgated a final rule on July 28, 2020, in which the U.S. EPA determined that risks from emissions of air toxics from this source category are acceptable and that the existing standards provide an ample margin of safety. Furthermore, under the technology review, the agency identified no cost-effective developments in controls, practices, or processes to achieve further emissions reductions. Petitions for review of the rule were filed in the United States Court of Appeals for the D.C. Circuit, in which the Company and the AISI intervened. The U.S. EPA is required by court order to issue a final rule by November 16, 2023. Because the U.S. EPA has yet to propose a revised taconite rule, any impacts are not estimable at this time.

The U.S. EPA is in the process of conducting its statutorily obligated residual risk and technology review of coke oven standards. Because the U.S. EPA has not completed its review of the Coke MACT regulations, any impacts related to the U.S. EPA’s review of the coke standards cannot be estimated at this time. The U.S. EPA is under a court-ordered deadline to complete the residual risk and technology rulemaking by May 23, 2024.

In response to Court orders that invalidated prior U.S. EPA determinations regarding ozone attainment interference, on April 6, 2022, the U.S. EPA proposed a Federal Implementation Plan (that would replace several pending or disapproved State Implementation Plans) for Regional Ozone Transport for the 2015 Ozone National Ambient Air Quality Standard. The proposed rule would affect electric generating units (EGUs) in 26 states and certain non-EGU industries, including, among several others, coke ovens, taconite production kilns, boilers, blast furnaces, basic oxygen furnaces, reheating furnaces, and annealing furnaces in 23 states, including those where U. S. Steel has operations. The impacts of the rule, if promulgated as proposed, could be material. U. S. Steel submitted comments on the proposed rule on June 21, 2022. The U.S. EPA announced the final rule on March 15, 2023. The final rule only included regulation of boilers and reheat furnaces for the iron and steel industry limiting the potential impacts. U. S. Steel is still reviewing the changes and will further evaluate the potential impacts to operations.

The CAA also requires the U.S. EPA to develop and implement National Ambient Air Quality Standards (NAAQS) for criteria pollutants, which include, among others, particulate matter (PM) - consisting of PM10 and PM2.5, lead, carbon monoxide, nitrogen dioxide, sulfur dioxide (SO2) and ozone.

In October 2015, the U.S. EPA lowered the NAAQS for ozone from 75 parts per billion (ppb) to 70 ppb. On November 6, 2017, the U.S. EPA designated most areas in which we operate as attainment with the 2015 standard. In a separate ruling, on June 4, 2018, the U.S. EPA designated other areas in which we operate as “marginal nonattainment” with the 2015 ozone standard. On December 6, 2018, the U.S. EPA published a final rule regarding implementation of the 2015 ozone standard. Because no state regulatory or permitting actions to bring the ozone nonattainment areas into attainment have yet to be proposed or developed for U. S. Steel facilities, the operational and financial impact of the ozone NAAQS cannot be reasonably estimated at this time. On December 31, 2020, the U.S. EPA published a final rule pursuant to its statutorily required review of NAAQS that retains the ozone NAAQS at 70 ppb. In January 2021, New York, along with several states and non-governmental organizations filed petitions for judicial review of the action with the United States Court of Appeals for the D.C. Circuit. Several other states and industry trade groups intervened in support of the U. S. EPA’s action. The case remains in abeyance before the court until December 15, 2023, as the U.S. EPA voluntarily reconsiders the ozone NAAQS. Because the U.S. EPA has yet to complete its reconsideration and proposes to revise or retain the 2020 ozone NAAQS, any impacts are not estimable at this time.

On December 18, 2020, the U.S. EPA published a final rule pursuant to its statutorily required review of NAAQS that retains the existing PM2.5 standards without revision. In early 2021, several states and non-governmental organizations filed petitions for judicial review of the action with the United States Court of Appeals for the D.C. Circuit. Several industry trade groups intervened in support of the U.S. EPA’s action. The case remains in abeyance before the court until March 1, 2023, as the U.S. EPA voluntarily reconsiders the PM2.5 NAAQS. On January 6, 2023, the U.S. EPA proposed to lower the annual PM2.5 NAAQS from the current 12 ug/m3 standard to within the range of 9.0 to 10.0 ug/m3. U. S. Steel is currently reviewing the proposal and comments to determine the potential impacts. Because the U.S. EPA has proposed the rule without specificity, any impacts are inestimable at this time.

For calendar year 2022, all Allegheny County ambient air quality monitors met all U.S. EPA health based National Ambient Air Quality Standards for the second consecutive year. On March 16, 2022, the U.S. EPA published a final rule, a clean data determination, showing that Allegheny County has attained the 2012 annual PM2.5 NAAQS based on the 2018 – 2020 ambient air quality data. Based on these and other data, ACHD submitted a Redesignation Request and Maintenance Plan to the U.S. EPA requesting that the U.S. EPA redesignate all of Allegheny County in attainment with the current PM2.5 NAAQS.

United States - Water

The U.S. EPA issued the final rule redefining the Waters of the United States (WOTUS), and it became effective March 1, 2023. The definition of WOTUS has had many changes and legal challenges over the last several years and this rule is no different. Due to certain state challenges and requests for injunctions, the Rule has been enjoined and is not in effect in Idaho and Texas. The new WOTUS rule expands the definition of what all waters will be considered to be a waters of the United States. The expansion of the WOTUS definition is likely to lead to additional legal challenges. It is also possible that the ruling in the U. S. Supreme court case Sackett v. EPA would impact the WOTUS definition as it relates to wetlands. The Sackett case was heard by the Court in the Fall 2022 term and a decision is expected sometime in 2023. U. S. Steel will continue to review and follow the final WOTUS definition and associated litigation for its potential impact on the Company.

OFF-BALANCE SHEET ARRANGEMENTS

U. S. Steel did not enter into any new material off-balance sheet arrangements during the first quarter of 2023.

INTERNATIONAL TRADE

U. S. Steel continues to face import competition, much of which is unfairly traded and fueled by massive global steel overcapacity, currently estimated to be over 620 million metric tons per year—more than six times the entire U.S. steel market and over twenty times total U.S. steel imports. These imports and overcapacity negatively impact the Company’s operational and financial performance. U. S. Steel continues to lead efforts to address these challenges that threaten the Company, our workers, our stockholders and our country’s national and economic security.

As of the date of this filing, pursuant to a series of Presidential Proclamations issued in accordance with Section 232 of the Trade Expansion Act of 1962, U.S. imports of certain steel products are subject to a 25 percent tariff, except imports from: (1) Argentina, Brazil, and South Korea, which are subject to restrictive quotas; (2) the European Union (EU), Japan and the United Kingdom (UK) that are melted and poured in the EU/Japan/UK, within quarterly tariff-rate quota (TRQ) limits; (3) Canada and Mexico, which are not subject to tariffs or quotas, but tariffs could be re-imposed on surging product groups after consultations; (4) Ukraine, which are exempt from tariffs until June 1, 2023; and (5) Australia, which are not subject to tariffs, quotas or an anti-surge mechanism.

-34-

The U.S. Department of Commerce (DOC) is managing a process in which U.S. companies may request and/or oppose temporary product exclusions from the Section 232 tariffs and quotas. U. S. Steel opposes exclusion requests for imported products that are the same as, or substitutes for, products manufactured by U. S. Steel.

Multiple legal challenges to the Section 232 action continue before the U.S. Court of International Trade (CIT) and the U.S. Court of Appeals for the Federal Circuit (CAFC), the latter which has consistently rejected constitutional and statutory challenges to the Section 232 action.

Since its implementation in March 2018, the Section 232 action has supported the U.S. steel industry’s and U. S. Steel’s investments in advanced steel production capabilities, technology, and skills, strengthening U.S. national and economic security. The Company continues to actively defend the Section 232 action.

In February 2019, the European Commission (EC) implemented a definitive safeguard on global steel imports in the form of TRQs that impose 25 percent tariffs on steel imports that exceed the TRQ limit, effective through June 2024. In December 2022, the EC initiated a fourth review of the safeguard.

Antidumping duties (AD) and countervailing duties (CVD or antisubsidy duties) apply in addition to the Section 232 tariffs, quotas, TRQs and the EC’s safeguard, and AD/CVD orders may continue beyond the Section 232 action and the EC’s safeguard. U. S. Steel continues to actively defend and maintain the 61 U.S. AD/CVD orders and 14 EU AD/CVD orders covering U. S. Steel products in multiple proceedings before the DOC, U.S. International Trade Commission (ITC), CIT, CAFC, the EC and European courts, and the World Trade Organization (WTO).

In January 2023, Cleveland-Cliffs and the USW filed new AD/CVD petitions on U.S. imports of tin mill products from eight countries. In March 2023, the ITC voted to continue the investigations. DOC’s preliminary AD/CVD determinations are expected by August 2023 and the ITC final phase hearing in the fourth quarter of 2023.

In February 2023, President Biden announced additional increases to normal tariffs of up to 70 percent on certain products from Russia, including pig iron, certain steel products and ferroalloys, effective April 1, 2023.

Additional tariffs of 7.5 to 25 percent continue to apply to certain U.S. imports from China, including certain raw materials used in steel production, semi-finished and finished steel products, and downstream steel-intensive products, pursuant to Section 301 of the Trade Act of 1974. The Office of the United States Trade Representative (USTR) is currently conducting a statutory review of the Section 301 tariffs.

The United States and EU are currently negotiating a global sustainable steel arrangement to restore market-oriented conditions and address carbon intensity that is targeted for completion by the end of 2023.

U. S. Steel will continue to execute a broad, global strategy to maximize opportunities and navigate challenges presented by imports, global steel overcapacity, and international trade law and policy developments.

Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2023, U. S. Steel’s disclosure controls and procedures were effective.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

-35-

There have not been any changes in U. S. Steel’s internal control over financial reporting that occurred during the fiscal quarter covered by this quarterly report, which have materially affected, or are reasonably likely to materially affect, U. S. Steel’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

GENERAL LITIGATION

On June 8, 2021, JSW Steel (USA) Inc. and JSW Steel USA Ohio, Inc. (collectively, JSW), U.S. based subsidiaries of Indian steelmaker JSW Steel, filed suit in the United States District Court for the Southern District of Texas against Nucor, U. S. Steel, AK Steel Holding Group and Cleveland-Cliffs (collectively, the JSW Defendants) alleging that the Defendants operated as a cartel and formed a conspiracy to boycott JSW from obtaining semi-finished steel slabs. JSW alleges that the JSW Defendants acted in violation of Section 1 of the Sherman Act and the Clayton Act (federal antitrust), and violation of the Texas Free Enterprise and Antitrust Act. JSW also alleges that the JSW Defendants formed a civil conspiracy in violation of Texas common law, and that the JSW Defendants tortiously interfered with JSW’s business relationships. The basis for JSW’s allegations relate to the JSW Defendants participation in the DOC's Section 232 process, including the JSW Defendants’ support of the enactment of the President’s Section 232 proclamation, statements made by the JSW Defendants after the enactment of Section 232, and the JSW Defendants’ participation in the Section 232 exclusion process. Plaintiffs seek monetary damages including $45 million for payment of Section 232 tariffs and unspecified amounts for financial penalties, termination fees and lost profits as well as other damages. U. S. Steel, along with the other JSW Defendants, filed a Motion to Dismiss the case on August 17, 2021. On February 17, 2022, the Court issued an opinion dismissing JSW’s antitrust complaint with prejudice. JSW filed a timely notice of appeal with the United States Court of Appeals for the Fifth Circuit. The Fifth Circuit held oral argument on the appeal on February 6, 2023 and we are awaiting a ruling from the Court. The Company continues to vigorously defend the matter.

On October 2, 2017, an Amended Shareholder Class Action Complaint was filed in the United States District Court for the Western District of Pennsylvania consolidating previously-filed actions. Separately, five related shareholder derivative lawsuits were filed in state and federal courts in Pittsburgh, Pennsylvania and the Delaware Court of Chancery. The underlying consolidated class action lawsuit alleges that U. S. Steel, certain current and former officers, an upper-level manager of the Company and the financial underwriters who participated in the August 2016 secondary public offering of the Company's common stock (collectively, the "Class Action Defendants") violated federal securities laws in making false statements and/or failing to discover and disclose material information regarding the financial condition of the Company. The lawsuit claims that this conduct caused a prospective class of plaintiffs to sustain damages during the period from January 27, 2016 to April 25, 2017 as a result of the prospective class purchasing the Company's common stock at artificially inflated prices and/or suffering losses when the price of the common stock dropped. The derivative lawsuits generally make the same allegations against the same officers and also allege that certain current and former members of the Board of Directors failed to exercise appropriate control and oversight over the Company and were unjustly compensated. The plaintiffs sought to recover losses that were allegedly sustained. The Class Action Defendants moved to dismiss plaintiffs’ claims. On September 29, 2018 the Court ruled on those motions granting them in part and denying them in part. On March 18, 2019, the plaintiffs withdrew the claims against the Class Action Defendants related to the 2016 secondary offering. As a result, the underwriters were no longer parties to the case. On December 31, 2019, the court granted the Plaintiffs' motion to certify the proceeding as a class action. The Company's appeal of that decision was denied. Discovery followed and concluded. On May 20, 2022, the Plaintiffs and Class Action Defendants agreed to settle the Shareholder Class Action in the amount of $40 million to be fully funded by the Company’s insurers. Following a hearing on March 20, 2023, the Court entered final approval of the settlement. The related derivative cases pending in federal and state court in Pennsylvania and state court in Delaware, which were previously stayed, are now proceeding. The Company will continue to vigorously defend against the derivative lawsuits.

On December 24, 2018, U. S. Steel's Clairton Plant experienced a fire, affecting portions of the facility involved in desulfurization of the coke oven gas generated during the coking process. With the desulfurization process out of operation as a result of the fire, U. S. Steel was not able to certify compliance with Clairton Plant’s Title V permit levels for sulfur emissions. U. S. Steel promptly notified ACHD, which has regulatory jurisdiction for the Title V permit, and updated the ACHD regularly on efforts to mitigate any potential environmental impacts until the desulfurization process was returned to normal operations. Of the approximately 2,400 hours between the date of the fire and April 4, 2019, when the Company resumed desulfurization, there were ten intermittent hours where average SO2 emissions exceeded the hourly NAAQS for SO2 at the Allegheny County regional air quality monitors located in Liberty and North Braddock boroughs, which are near U. S. Steel's Mon Valley Works facilities. On April 29, 2019, PennEnvironment and Clean Air Council, both environmental, non-governmental organizations filed a Complaint in Federal Court in the Western District of Pennsylvania. The ACHD was subsequently granted intervenor status. Collectively the parties seek injunctive relief and civil penalties regarding the alleged Permit violations following the fire. Discovery has concluded. The court denied the parties’ respective Motions for Summary Judgment. A non-jury trial which was scheduled to take place in April and May of 2023 is being held in abeyance as the parties reached a tentative settlement agreement, signed a term sheet, and advised the Court accordingly. The parties are working to draft a Consent Decree to memorialize the settlement terms.

ENVIRONMENTAL PROCEEDINGS

The following is a summary of the proceedings of U. S. Steel that were pending or contemplated as of March 31, 2023, under federal and state environmental laws, and which U. S. Steel reasonably believes may result in monetary sanctions of at least $1 million (the threshold chosen by U. S. Steel as permitted by Item 103 of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended). Information about specific sites where U. S. Steel is or has been engaged in significant clean up or remediation activities is also summarized below. Except as described herein, it is not possible to accurately predict the ultimate outcome of these matters.

CERCLA Remediation Sites

Claims under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) have been raised with respect to the cleanup of various waste disposal and other sites. Under CERCLA, potentially responsible parties (each, a PRP) for a site include current owners and operators, past owners and operators at the time of disposal, persons who arranged for disposal of a hazardous substance at a site and persons who transported a hazardous substance to a site. CERCLA imposes strict and joint and several liabilities. Because of various factors, including the ambiguity of the regulations, the difficulty of identifying the responsible parties for any particular site, the complexity of determining the relative liability among them, the uncertainty as to the most desirable remediation techniques, and the amount of damages and cleanup costs and the time period during which such costs may be incurred, we are unable to reasonably estimate U. S. Steel’s ultimate liabilities under CERCLA.

As of March 31, 2023, U. S. Steel has received information requests or been identified as a PRP at a total of four CERCLA sites, three of which have liabilities that have not been resolved. Based on currently available information, which is in many cases preliminary and incomplete, management believes that U. S. Steel’s liability for CERCLA cleanup and remediation costs at the other site will be over $5 million as described below.

Duluth Works

The former U. S. Steel Duluth Works site was placed on the National Priorities List under CERCLA in 1983 and on the State of Minnesota’s Superfund list in 1984. Liability for environmental remediation at the site is governed by a Response Order by Consent executed with the MPCA in 1985 and a Record of Decision signed by MPCA in 1989. U. S. Steel has partnered with the Great Lakes National Program Office (GLNPO) of the U.S. EPA Region 5 to address contaminated sediments in the St. Louis River Estuary and several other operable units that could impact the estuary if not addressed. An amendment to the Project Agreement between U. S. Steel and GLNPO was executed during the second quarter of 2018 to recognize the initial costs associated with implementing the first two phases of the proposed remedial plan at the site.

Remediation contracts were issued by both USS and GLNPO for the first phase of the remedial work at the site during the fourth quarter of 2020. USS and GLNPO have completed the second phase of work at the site which extended through early 2022. The final phase of the remedial design has been defined and another amendment to the Project Agreement between U.S. Steel and GLNPO was executed in December 2021. Execution of this final phase is in progress and is expected to extend through 2023. USS' portion of additional, design, oversight costs, and implementation of all three phases of the preferred remedial alternative on the upland property and Estuary are currently estimated as of March 31, 2023 at approximately $20 million.

Resource Conservation Recovery Act (RCRA) and Other Remediation Sites

U. S. Steel may be liable for remediation costs under other environmental statutes, both federal and state, or where private parties are seeking to impose liability on U. S. Steel for remediation costs through discussions or litigation. There are eight such sites where remediation is being sought involving amounts in excess of $1 million. Based on currently available information, which is in many cases preliminary and incomplete, management believes that liability for cleanup and remediation costs in connection with four sites may involve remediation costs between $1 million and $5 million per site and four sites are estimated to, or could have, costs for remediation, investigation, restoration or compensation in excess of $5 million per site.

For more information on the status of remediation activities at U. S. Steel’s significant sites, see the discussions below.

Gary Works

On October 23, 1998, the U.S. EPA issued a final Administrative Order on Consent (Order) addressing Corrective Action for Solid Waste Management Units (SWMU) throughout Gary Works. This Order requires U. S. Steel to perform an RCRA Facility Investigation, a Corrective Measures Study and Corrective Measure Implementation. Evaluations are underway at six groundwater areas on the east side of the facility. A remedial groundwater treatment system has been operating at one of the six areas since 2021. An Interim Stabilization Measure work plan was recently approved by the U.S. EPA for a second area and a contractor is completing installation of the remedial system. Until the remaining Phase I work and Phase II field investigations are completed, it is not possible to assess what additional expenditures will be necessary for Corrective Action projects at Gary Works. In total, the accrued liability for Corrective Action projects is approximately $26 million as of March 31, 2023, based on our current estimate of known remaining costs.

-37-

Geneva Works

At U. S. Steel’s former Geneva Works, liability for environmental remediation, including the closure of three hazardous waste impoundments and facility-wide corrective action, has been allocated between U. S. Steel and the current property owner pursuant to an agreement and a permit issued by the Utah Department of Environmental Quality (UDEQ). Having completed the investigation on a majority of the remaining areas identified in the permit, U. S. Steel had determined the most effective means to address the remaining impacted material was to manage those materials in a previously approved on-site Corrective Action Management Unit (CAMU). U. S. Steel awarded a contract for the implementation of the CAMU project during the fourth quarter of 2018. Construction, waste stabilization and placement, along with closure of the CAMU, were substantially completed in the fourth quarter of 2020. U. S. Steel has an accrued liability of approximately $18 million as of March 31, 2023 for our estimated share of the remaining costs of remediation at the site.

USS-UPI LLC

In February 2020, U. S. Steel purchased the remaining 50 percent interest in USS-POSCO Industries, a former joint venture that is located in Pittsburg, California between subsidiaries of U. S. Steel and POSCO, now known as USS-UPI, LLC. Prior to formation of the joint venture, UPI's facilities were previously owned and operated solely by U. S. Steel, which assumed responsibility for the existing environmental conditions. U. S. Steel continues to monitor the impacts of the remedial plan implemented in 2016 to address groundwater impacts from trichloroethylene at SWMU 4. Evaluations continue for the SWMUs, known as the Northern Boundary Group, and it is likely that corrective measures will be required, but it is not possible at this time to define a scope or estimate costs for what may be required by the California Department of Toxic Substances Control. As such, there has been no material change in the status of the project during the three months ended March 31, 2023. As of March 31, 2023, approximately $229,000 has been accrued for ongoing environmental studies, investigations and remedy monitoring. Significant additional costs associated with this site are possible and are referenced in Note 21 to the Condensed Consolidated Financial Statements “Contingencies and Commitments - Environmental Matters - Remediation Projects - Projects with Ongoing Study and Scope Development.”

Fairfield Works

A consent decree was signed by U. S. Steel, the U.S EPA and the U.S. Department of Justice and filed with the United States District Court for the Northern District of Alabama (United States of America v. USX Corporation) in December 1997. In accordance with the consent decree, U. S. Steel initiated an RCRA corrective action program at the Fairfield Works facility. The Alabama Department of Environmental Management, with the approval of the U.S. EPA, assumed primary responsibility for regulation and oversight of the RCRA corrective action program at Fairfield Works. While work continues on different aspects of the program, there has been no material change in the status of the project during the three months ended March 31, 2023. In total, the accrued liability for remaining work under the Corrective Action Program, was approximately $287,000 as of March 31, 2023. Significant additional costs associated with this site are possible and are referenced in Note 21 to the Condensed Consolidated Financial Statements “Contingencies and Commitments - Environmental Matters - Remediation Projects - Projects with Ongoing Study and Scope Development.”

Air Related Matters

Granite City Works

In October 2015, Granite City Works received a Violation Notice from the Illinois Environmental Protection Agency (IEPA) in which the IEPA alleges that U. S. Steel violated the emission limits for nitrogen oxides (NOx) and volatile organic compounds from the Basic Oxygen Furnace Electrostatic Precipitator Stack. In addition, the IEPA alleges that U. S. Steel exceeded its natural gas usage limit at its CoGeneration Boiler. U. S. Steel responded to the notice and is currently discussing resolution of the matter with the IEPA.

Although discussions with IEPA regarding the foregoing alleged violations are ongoing and the resolution of these matters is uncertain at this time, it is not anticipated that the result of those discussions will be material to U. S. Steel.

Minnesota Ore Operations

On February 6, 2013, the U.S. EPA published a FIP that applies to taconite facilities in Minnesota. The FIP establishes and requires emission limits and the use of low NOx reduction technology on indurating furnaces as Best Available Retrofit Technology (BART). While U. S. Steel installed low NOx burners on three furnaces at Minntac and is currently obligated to install low NOx burners on the two other furnaces at Minntac pursuant to existing agreements and permits, the rule would require the installation of a low NOx burner on the one furnace at Keetac for which U. S. Steel did not have an otherwise existing obligation. U. S. Steel estimates expenditures associated with the installation of low NOx burners of as much as $25 million to $30 million. In 2013, U. S. Steel filed a petition for administrative reconsideration to the U.S. EPA and a petition for judicial review of the 2013 FIP and denial of the Minnesota SIP to the Eighth Circuit. In April 2016, the U.S. EPA promulgated a revised FIP with the same substantive requirements for U. S. Steel. In June 2016, U. S. Steel filed a petition for administrative reconsideration of the 2016 FIP to the U.S. EPA and a petition for judicial review of the 2016 FIP before the Eighth Circuit Court of Appeals. While the proceedings regarding the petition for judicial review of the 2013 FIP remained stayed, oral arguments regarding the petition for judicial review of the 2016 FIP were heard by the Eighth Circuit Court of Appeals on November 15, 2017. Thus, both petitions for

-38-

judicial review remain with the Eighth Circuit. On December 4, 2017, the U.S. EPA published a notification in the Federal Register in which the U.S. EPA denied U. S. Steel’s administrative petitions for reconsideration and stay of the 2013 FIP and 2016 FIP. On February 1, 2018, U. S. Steel filed a petition for judicial review of the U.S. EPA’s denial of the administrative petitions for reconsideration to the Eighth Circuit Court of Appeals. The U.S. EPA and U. S. Steel reached a settlement regarding the five indurating lines at Minntac. After proposing a revised FIP and responding to public comments, on March 2, 2021, the U.S. EPA promulgated a final revised FIP incorporating the conditions and limits for Minntac to which the parties agreed. U. S. Steel and the U.S. EPA continue to negotiate resolution for Keetac.

Mon Valley Works

On November 9, 2017, the U.S. EPA Region III and ACHD jointly issued a Notice of Violation (NOV) regarding the Company’s Edgar Thomson facility in Braddock, Pennsylvania. In addition, on November 20, 2017, ACHD issued a separate, but related, NOV to the Company regarding the Edgar Thomson facility. In the NOVs, based upon their inspections and review of documents collected, the agencies allege that the Company has violated the CAA by exceeding the allowable visible emission standards from certain operations during isolated events. In addition, the agencies allege that the Company has violated certain maintenance, reporting, and recordkeeping requirements. U. S. Steel met with the U.S. EPA Region III and ACHD several times. On May 17, 2022, the United States Department of Justice (the DOJ), the U.S. EPA Region III and the ACHD filed a Complaint in the United States District Court for the Western District of Pennsylvania and lodged a proposed Consent Decree negotiated in good faith between U. S. Steel, DOJ, the U.S. EPA Region III and ACHD that will resolve this matter. On December 16, 2022, the Court approved the Consent Decree and it is currently in effect.

On March 2, 2022, the Company received a stipulated penalty demand for $0.9 million from the Allegheny County Health Department (ACHD) pursuant to the June 2019 Settlement Agreement and Order (SAO) between the Company and ACHD. In the demand notice, ACHD alleges that based upon daily visible emission observation inspections occurring April 1, 2021 through December 31, 2021, the Company’s Clairton plant violated applicable opacity standards from coke battery fugitive emission sources. The Company disagrees with the bases for the demand. The Company has initiated dispute resolution in accordance with the SAO and is attempting to reach a negotiated resolution of the matter.
