NOTE 1. Nature of Operations and Significant Accounting Policies

Background

CSX Corporation together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations.

CSX's principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 20,000 route-mile rail network and serves major population centers in 26 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. The Company's intermodal business links customers to railroads via trucks and terminals. CSXT is also responsible for the Company's real estate sales, leasing, acquisition, and management and development activities, substantially all of which are focused on supporting railroad operations.

Other entities

In addition to CSXT, the Company’s subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. Quality Carriers is the largest provider of bulk liquid chemicals truck transportation in North America. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States and also performs drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest Transflo markets are chemicals and agriculture, which includes shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.

Basis of Presentation

In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the consolidated financial statements and accompanying notes. Where applicable, prior year information has been reclassified to conform to the current presentation. Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted from these interim financial statements. CSX suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in CSX's most recent annual report on Form 10-K as well as any subsequently filed current reports on Form 8-K.

Fiscal Year

The Company's fiscal periods are based upon the calendar year. Except as otherwise specified, references to “first quarter(s)” or “three months” indicate CSX's fiscal periods ending March 31, 2026, and March 31, 2025, and references to "year-end" indicate the fiscal year ended December 31, 2025.

New Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This standard update requires additional disclosures about certain expenses in commonly presented expense captions. The Company is required to adopt the guidance for its 2027 annual report on Form 10-K, though early adoption is permitted. The Company is currently evaluating the impact of these amendments on its disclosures, but this standard update will not impact the Company's results of operations or financial position.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software. This standard update modernizes the capitalization criteria for internal-use software, eliminating references to project stages and instead requiring that projects meet completion probability criteria before costs can be capitalized. This guidance is effective beginning first quarter 2028, though early adoption is permitted, and can be applied using a prospective, retrospective, or modified transition approach. The Company is currently evaluating the impact of these amendments but does not anticipate that adoption will have a material impact on the Company's results of operations or financial position.

In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants by Business Entities. This standard establishes the accounting for government grants received by a business entity, including guidance for both grants related to an asset and grants related to income. This guidance is effective beginning first quarter 2029, though early adoption is permitted, and can be applied using a modified prospective, modified retrospective, or full retrospective transition approach. The Company is currently evaluating the impact of this guidance but does not anticipate that adoption will have a material impact on the Company's results of operations or financial position.

NOTE 2. Earnings Per Share

The following table sets forth the computation of basic earnings per share and earnings per share, assuming dilution.

	First Quarters — 2026	2025
Numerator (Dollars in Millions) :
Net Earnings	$ 807	$ 646
Denominator (Units in Millions) :
Average Common Shares Outstanding	1,860	1,890
Other Potentially Dilutive Common Shares	2	2
Average Common Shares Outstanding, Assuming Dilution	1,862	1,892
Net Earnings Per Share, Basic	$ 0.43	$ 0.34
Net Earnings Per Share, Assuming Dilution	$ 0.43	$ 0.34

Basic earnings per share is based on the weighted-average number of shares of common stock outstanding. Earnings per share, assuming dilution, is based on the weighted-average number of shares of common stock outstanding and common stock equivalents adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments. CSX's potentially dilutive instruments are made up of equity awards including employee stock options, performance units and restricted stock units.

When calculating diluted earnings per share, the potential shares that would be outstanding if all in-the-money outstanding stock options were exercised are included, net of shares CSX could repurchase using the proceeds from these hypothetical exercises. The total average outstanding stock options that were excluded from the diluted earnings per share calculation because their effect was antidilutive is in the table below.

	First Quarters — 2026	2025
Antidilutive Stock Options Excluded from Diluted EPS (Units in Millions)	2	4

NOTE 2. Earnings Per Share, continued

Share Repurchases

During fourth quarter 2023, the Company began repurchasing shares under the $ 5 billion share repurchase program approved in October 2023. Total repurchase authority remaining was $ 989 million as of March 31, 2026.

Share repurchases may be made through a variety of methods including, but not limited to, open market purchases, purchases pursuant to Rule 10b5-1 plans, accelerated share repurchases and negotiated block purchases. The timing of share repurchases depends upon management's assessment of marketplace conditions and other factors, and the program remains subject to the discretion of the Board of Directors. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances. Shares are retired immediately upon repurchase. In accordance with the Equity Topic in the Accounting Standards Codification ("ASC"), the excess of repurchase price over par value is recorded in retained earnings.

During first quarters ended March 31, 2026, and March 31, 2025, the Company engaged in the following repurchase activities:

	First Quarters — 2026	2025
Shares Repurchased (Millions)	6	24
Cost of Shares (Dollars in Millions)	$ 222	$ 751
Average Price Paid per Share	$ 39.02	$ 31.66

The Inflation Reduction Act of 2022 imposes a nondeductible 1% excise tax on the net value of most share repurchases made after December 31, 2022. Excise tax commensurate with net share repurchases is reflected in equity and a corresponding liability for excise taxes payable is included in other current liabilities on the consolidated balance sheet. The cost of shares repurchased shown in the table above excludes the impact of this excise tax.

Dividend Increase

On February 26, 2026, the Company's Board of Directors authorized an 8 % increase in the quarterly cash dividend to $ 0.14 per common share effective March 2026.

NOTE 3. Stock Plans and Share-Based Compensation

Under CSX's share-based compensation plans, awards consist of performance units, stock options and restricted stock units for management and stock grants for directors. Share-based compensation expense for awards under share-based compensation plans is measured using the fair value of the award on the grant date and is recognized on a straight-line basis over the service period of the respective award. Alternatively, expense is recognized upon death or over an accelerated service period for employees whose agreements allow for continued vesting upon retirement or separation. Forfeitures are recognized as they occur. Total pre-tax expense and income tax benefits associated with share-based compensation are shown in the table below. Income tax benefits include impacts from option exercises and the vesting of other equity awards.

(Dollars in Millions)	First Quarters — 2026	2025
Share-Based Compensation Expense:
Restricted Stock Units	$ 4	$ 6
Stock Options	3	3
Stock Awards for Directors	2	3
Employee Stock Purchase Plan	2	2
Performance Units	2	—
Total Share-Based Compensation Expense	$ 13	$ 14
Income Tax Benefit	$ 7	$ 3

Long-term Incentive Plan

In February 2026, the Company granted the following awards under a new long-term incentive plan ("LTIP") for the years 2026 through 2028, which was adopted under the CSX 2019 Stock and Incentive Award Plan.

	Granted (Thousands)	Weighted Avg. Fair Value
Performance Units	637	$ 50.18
Restricted Stock Units	255	42.65
Stock Options	1,271	12.83

NOTE 3. Stock Plans and Share-Based Compensation, continued

Performance Units

Units vest based on performance approximately three years after grant with payouts made in CSX common stock. The 2026-2028 plan's performance measures are Return on Invested Capital (“ROIC”) and relative Total Shareholder Return (“rTSR”). These measures are assessed independently of each other and weighted at 60 % ROIC and 40 % rTSR, respectively, for a total payout of 100 % of the grant value. If the maximum ROIC and maximum rTSR are achieved, then the measures would generate a payout of 120 % and 80 %, respectively, for a total payout at 200 %.

ROIC is calculated by dividing net operating profit after taxes, adjusting for certain items as defined in the Plan, by invested capital to measure how effectively the Company uses its capital to generate returns. Net operating profit after taxes is calculated as net income, adjusted to exclude the cost and tax impact of interest, including implied lease interest. Invested capital is composed of the average of the Company's debt, including financing and operating leases, and shareholders equity as of the end of the most recent five quarters.

The rTSR measure shows how the Company performed compared to its competitors by ranking the companies in the S&P 500 Industrials from highest to lowest according to their respective TSRs and calculating the percentile performance of CSX relative to the peer companies. The fair values of the rTSR component of performance units were calculated using a Monte-Carlo simulation model.

Stock Options

Stock options were granted with ten-year terms and vest over three years in equal installments each year on the anniversary of the grant date. These awards are time-based and are not based upon attainment of performance goals. The fair values of stock option awards were determined at the grant date using the Black-Scholes valuation model.

Restricted Stock Units

The restricted stock units awarded vest over three years in equal installments each year on the anniversary of the grant date and are settled in CSX common stock on a one -for-one basis. These awards are time-based and are not based upon CSX's attainment of performance goals.

Other Awards

Awards are periodically granted outside of the annual LTIP program, subject to approval by the Board of Directors, Compensation and Talent Management Committee, or Chief Executive Officer ("CEO") as appropriate. Immaterial awards outside of the annual LTIP program were granted to certain management employees other than senior executives during the first quarters ended March 31, 2026, and March 31, 2025.

For more information related to the Company's outstanding long-term incentive compensation, including units granted under previous LTIPs, see CSX's most recent annual report on Form 10-K.

NOTE 4. Casualty, Environmental and Other Reserves

Personal injury and environmental reserves are considered critical accounting estimates due to the need for management judgment. Casualty, environmental and other reserves are reflected in the consolidated balance sheets as shown in the table below.

(Dollars in Millions)	March 31, 2026 — Current	Long-term	Total	December 31, 2025 — Current	Long-term	Total
Casualty:
Personal Injury	$ 60	$ 94	$ 154	$ 60	$ 94	$ 154
Occupational	6	53	59	6	53	59
Total Casualty	66	147	213	66	147	213
Environmental	49	105	154	49	107	156
Other	64	48	112	69	41	110
Total	$ 179	$ 300	$ 479	$ 184	$ 295	$ 479

These liabilities are accrued when probable and reasonably estimable in accordance with the Contingencies Topic in the ASC. Actual settlements and claims received could differ, and final outcomes of these matters cannot be predicted with certainty. Considering the legal defenses currently available, the liabilities that have been recorded and other factors, it is the opinion of management that none of these items individually, when finally resolved, will have a material adverse effect on the Company's financial condition, results of operations or liquidity. Should a number of these items occur in the same period, however, their combined effect could be material in that particular period.

Casualty

Casualty reserves represent accruals for personal injury, occupational disease and occupational injury claims primarily related to railroad operations. The Company's self-insured retention amount for casualty claims is $ 100 million per occurrence as discussed at Note 5, Commitments and Contingencies . Currently, no individual claim is expected to exceed the self-insured retention amount.

Personal Injury

Personal injury reserves represent liabilities for employee work-related and third-party injuries. Work-related injuries for CSXT employees are primarily subject to the Federal Employers’ Liability Act (“FELA”). CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. An analysis is performed by the actuary quarterly and is reviewed by management. This analysis did not result in a material adjustment to the personal injury reserve in the quarters ended March 31, 2026, or March 31, 2025.

NOTE 4. Casualty, Environmental and Other Reserves, continued

Occupational

Occupational reserves represent liabilities arising from allegations of exposure to certain materials in the workplace (such as solvents, soaps, chemicals and diesel fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions (such as repetitive stress injuries). The Company retains an independent actuary to analyze the Company’s historical claim filings, settlement amounts, and dismissal rates to assist in determining future anticipated claim filing rates and average settlement values. This analysis is performed by the actuary and reviewed by management quarterly. The analysis did not result in a material adjustment to the occupational reserve in the quarters ended March 31, 2026, or March 31, 2025.

Environmental

The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 210 environmentally impaired sites. Many of these are, or may be, subject to remedial action under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), also known as the Superfund Law, or similar state statutes. Most of these proceedings arose from environmental conditions on properties used for ongoing or discontinued railroad operations. A number o f these proceedings, however, are based on allegations that the Company, or its predecessors, sent hazardous substances to facilities owned or operated by others for treatment, recycling or disposal. In addition, some of the Company's land holdings were leased to others for commercial or industrial uses that may have resulted in releases of hazardous substances or other regulated materials onto the property and could give rise to proceedings against the Company.

In any such proceedings, the Company is subject to environmental clean-up and enforcement actions under the Superfund Law, as well as similar state laws that may impose joint and several liability for clean-up and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. These costs could be substantial.

The Company reviews its role with respect to each site identified at least quarterly. Based on management's review process, amounts have been recorded to cover contingent anticipated future environmental remediation costs with respect to each site to the extent such costs are reasonably estimable and probable. Payments related to these liabilities are expected to be made over the next several years. Environmental remediation costs are included in purchased services and other on the consolidated income statements.

Currently, the Company does not possess sufficient information to reasonably estimate the amounts of additional liabilities, if any, on some sites until completion of future environmental studies. In addition, conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. Based upon information currently available, however, the Company believes its environmental reserves accurately reflect the estimated cost of remedial actions currently required.

Other

Other reserves include liabilities for various claims, such as automobile, property, general liability, workers' compensation and longshoremen disability claims.

NOTE 5. Commitments and Contingencies

Insurance

The Company maintains insurance programs with substantial limits for property damage, including resulting business interruption, as well as casualty claims, which includes third-party liability. A certain amount of risk is retained by the Company on each insurance program. Under its property insurance program, the Company retains all risk up to $ 200 million per occurrence for losses from floods and named windstorms and up to $ 175 million per occurrence for other property losses. For casualty claims, the Company retains all risk up to $ 100 million per occurrence. CSX purchases insurance coverage above its full self-retention amounts and it retains a percentage of risk at various layers as well. While the Company believes its insurance coverage is adequate, future claims could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates.

Legal

The Company is involved in litigation incidental to its business and is a party to a number of legal actions and claims, various governmental proceedings and private civil lawsuits, including, but not limited to, those related to fuel surcharge practices, tax matters, environmental and hazardous material exposure matters, FELA and labor claims by current or former employees, other personal injury or property claims and disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory as well as punitive damages and others are, or are purported to be, class actions. While the final outcomes of these matters cannot be predicted with certainty, considering, among other things, the legal defenses available and liabilities that have been recorded along with applicable insurance, it is currently the opinion of management that none of these pending items is likely to have a material adverse effect on the Company's financial condition, results of operations or liquidity. An unexpected adverse resolution of one or more of these items, however, could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.

The Company is able to estimate a range of possible loss for certain matters for which a loss is reasonably possible in excess of reserves established. The Company has estimated this range to be $ 2 million to $ 73 million in the aggregate at March 31, 2026. This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.

Fuel Surcharge Antitrust Litigation

In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were transferred to federal court in the District of Columbia for coordinated or consolidated pre-trial proceedings. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court’s ruling.

NOTE 5. Commitments and Contingencies, continued

Although the class was not certified, individual shippers have since brought claims against the railroads, which were also transferred to federal court in the District of Columbia for pre-trial proceedings but before a different judge. In March 2024, the original case was reassigned to the judge in the later-filed case. The railroads filed motions for summary judgment on July 17, 2024, with the briefing completed in December 2024. The judge held a hearing on the railroads' summary judgment motions on June 18, 2025, and granted summary judgment in favor of the railroads on June 24, 2025, ordering the cases closed. Most of the individual shippers have appealed the summary judgment ruling to the U.S. Court of Appeals for the D.C. Circuit. Briefing on the appeal is scheduled to conclude on April 23, 2026, after which the court will schedule oral argument.

Environmental

CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the “Property”). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17 -mile Lower Passaic River Study Area (the "Study Area”). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia’s share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties.

For the lower eight miles of the Study Area, EPA issued its Record of Decision detailing the agency’s mandated remedial process in March 2016. Occidental Chemical Corporation ("Occidental") performed the remedial design for the lower eight -mile portion of the Study Area pursuant to a consent order with EPA. EPA approved the design in May 2024.

For the remaining upper nine miles of the Study Area, EPA selected an interim remedy in a Record of Decision dated September 28, 2021. On March 2, 2023, EPA issued an administrative order requiring Occidental to design the interim remedy for the upper nine miles of the Study Area.

Potentially responsible parties, including Pharmacia, are participating in an EPA-directed allocation and settlement process to assign responsibility related to the lower river and the entire Study Area, respectively. CSXT participated in the EPA-directed allocation and settlement process on behalf of Pharmacia.

On March 2, 2022, EPA issued a Notice Letter to Pharmacia, Occidental and eight other parties alleging they are liable under Section 107(a) of CERCLA for releases or threatened releases of hazardous substances and requesting each party, individually or collectively, submit good faith offers to EPA in connection with the entire Study Area. CSXT, on behalf of Pharmacia, responded to the Notice Letter and submitted a good faith offer to EPA on June 27, 2022, following meetings with a mediator from EPA’s Conflict Prevention and Resolution Center.

NOTE 5. Commitments and Contingencies, continued

On November 21, 2023, EPA notified the United States District Court for the District of New Jersey ("Court") that it intended to move to enter a Consent Decree ("CD") with a group of potentially responsible parties. On January 31, 2024, EPA filed a motion to enter a modified CD with 82 potentially responsible parties, not including Pharmacia, requiring payment of $ 150 million to resolve their liability with respect to the entire Study Area. On April 1, 2024, Occidental filed its opposition to EPA's motion to enter the CD. Several other non-settling parties, including Pharmacia, filed comments concerning (but not opposing) entry of the CD. On December 18, 2024, the Court entered and approved the CD, which is now under appeal. Negotiations with EPA and other parties to resolve Pharmacia's liability continue.

On October 2, 2025, Occidental Petroleum Corporation announced a definitive agreement for Berkshire Hathaway to acquire Occidental’s chemical business, which had been separated into its own entity as a result of Occidental having completed a divisive merger under Texas law that divided its overall business into two entities. A newly formed Texas corporation also called Occidental Chemical Corporation (“New Occidental”), now holds the company’s manufacturing assets, while Environmental Resource Holdings, also a Texas corporation (“ERH”), holds legacy environmental liabilities, including those related to the Lower Passaic River. This transaction, through which Occidental Petroleum Corporation sold all equity interests in New Occidental to Berkshire Hathaway, closed on January 2, 2026. On February 6, 2026, a group of parties, including Pharmacia, filed a complaint in New Jersey federal court seeking a declaratory judgment that New Occidental remains jointly and severally liable with ERH for CERCLA liability related to the Lower Passaic River.

CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental, which is seeking to recover its past and future costs associated with the remediation of the entire Study Area. Alternatively, Occidental seeks to compel some, or all, of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in a federal lawsuit filed by Occidental on June 30, 2018, and one of 37 defendants in a federal lawsuit filed by Occidental on March 24, 2023. Both of these lawsuits are stayed pending resolution of the CD action. CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property.

Based on currently available information, the Company does not believe its share of remediation costs as determined by the EPA-directed allocation with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.

See Note 4, Casualty, Environmental and Other Reserves , for additional information on the Company's environmental liabilities.

NOTE 6. Employee Benefit Plans

The Company sponsors defined benefit pension plans principally for salaried, management personnel. All plans are closed to new participants.

Independent actuaries compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management. Only the service cost component of net periodic benefit costs is included in labor and fringe expense on the consolidated income statement. All other components of net periodic benefit cost are included in other income - net.

	Pension Benefits Cost
	First Quarters
(Dollars in Millions)	2026	2025
Service Cost Included in Labor and Fringe	$ 6	$ 5
Interest Cost	25	27

Amortization of Net Loss	6	6
Total Included in Other Income - Net	( 6 )	( 7 )
Net Periodic Benefit Cost/ (Credit)	$ —	$ ( 2 )

Qualified pension plan obligations are funded in accordance with regulatory requirements and with an objective of meeting or exceeding minimum funding requirements necessary to avoid restrictions on flexibility of plan operation and benefit payments. No contributions to the Company's qualified pension plans are expected in 2026.

NOTE 7. Debt and Credit Agreements

Total activity related to long-term debt during the quarter ended March 31, 2026, is shown in the table below. For fair value information related to the Company's long-term debt, see Note 9, Fair Value Measurements .

Interest Rate Derivatives

Fair Value Hedges

In first quarter 2025, CSX entered into two fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the Secured Overnight Financing Rate ("SOFR") on a cumulative $ 250 million of fixed rate outstanding notes which are due in 2055. The cumulative fair value of these swaps, which is included in other long-term assets on the consolidated balance sheet, was an asset of $ 7 million and $ 9 million as of March 31, 2026, and December 31, 2025, respectively.

CSX has seven other fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to SOFR on a cumulative $ 1.1 billion of fixed rate outstanding notes which are due between 2032 and 2040. These swaps are comprised of two swaps entered during 2023 (“2023 swaps”) and five swaps entered during 2022 (“2022 swaps”). The cumulative fair value of the 2023 swaps was an asset of $ 12 million and $ 14 million as of March 31, 2026, and December 31, 2025, respectively, and is included in other long-term assets on the consolidated balance sheet. The cumulative fair value of the 2022 swaps was a liability of $ 92 million and $ 87 million as of March 31, 2026, and December 31, 2025, respectively, and is included in other long-term liabilities on the consolidated balance sheet.

The swaps expire between 2032 and 2055. If settled early, the remaining cumulative fair value adjustment to the hedged notes will be amortized over the remaining life of the associated notes. The cumulative adjustment to the hedged notes is included in long-term debt on the consolidated balance sheet as shown in the following table below.

(Dollars in Millions)	March 31, 2026	December 31, 2025
Notional Value of Hedged Notes	$ 1,300	$ 1,300
Fair Value Asset Adjustment to Hedged Notes	19	23
Fair Value Liability Adjustment to Hedged Notes	( 92 )	( 87 )
Carrying Amount of Hedged Notes	$ 1,227	$ 1,236

NOTE 7. Debt and Credit Agreements , continued

Gains and losses resulting from changes in fair value of the interest rate swaps offset changes in the fair value of the hedged portion of the underlying debt with no gain or loss recognized due to hedge ineffectiveness. The difference in the net fixed-to-float interest settlement on the derivatives is recognized in interest expense and is summarized as follows.

(Dollars in Millions)	First Quarters — 2026	2025
Interest Expense Impact (Increase)/ Decrease	$ ( 3 )	$ ( 5 )

Cash Flow Hedges

The Company had forward starting interest rate swaps, designated as cash flow hedges in accordance with the Derivatives and Hedging Topic in the ASC, that had an aggregate notional value of $ 500 million at inception. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of $ 850 million of 3.25 % notes due in 2027. CSX executed a final settlement of the notional value of the cash flow hedges in second quarter 2024, so no unsettled aggregate notional value of these swaps remained and there is no related asset or liability as of March 31, 2026, and December 31, 2025.

The unrealized gain associated with the settled portion of the swaps is recorded net of tax in accumulated other comprehensive income ("AOCI") on the consolidated balance sheet. As these swaps were fully settled in 2024, subsequent gains or losses are only attributable to tax effects. The unrealized gain associated with the settled portion of the hedges will continue to be classified in AOCI until the associated debt instrument is issued in the future. The unrealized gain in AOCI will be recognized in earnings as an adjustment to interest expense over the same period during which the hedged transaction affects earnings. See Note 9, Fair Value Measurements , and Note 10, Other Comprehensive Income (Loss) , for additional information about the Company's swaps.

NOTE 7. Debt and Credit Agreements , continued

Credit Facility

The Company has a $ 1.2 billion unsecured revolving credit facility backed by a diverse syndicate of banks. This facility allows same-day borrowings at floating interest rates, based on SOFR or an agreed-upon replacement reference rate, plus a spread that depends upon CSX's senior unsecured debt ratings. This facility expires in February 2028. As of March 31, 2026, the Company had no outstanding balances under this facility.

Commitment fees and interest rates payable under the facility were similar to fees and rates available to comparably rated investment-grade borrowers. As of first quarter 2026, CSX was in compliance with all covenant requirements under this facility.

Commercial Paper

Under its commercial paper program, which is backed by the revolving credit facility, the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount o f $ 1.0 billion outstanding at any time. Proceeds from issuances of the notes are used for general corporate purposes. At March 31, 2026, the Company had no outstanding debt under the commercial paper program.

NOTE 8. Revenues

The Company’s revenues are primarily derived from the transportation of freight as performance obligations that arise from its contracts with customers are satisfied. The below table presents the Company’s revenues disaggregated by market as this best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Fuel surcharge revenue is included in the individual markets.

(Dollars in Millions)	First Quarters — 2026	2025
Chemicals	$ 722	$ 698
Agricultural and Food Products	409	408
Automotive	275	271

Intermodal	518	493
Coal	458	461
Trucking	202	202
Other	116	115
Total	$ 3,482	$ 3,423

The Company’s accounts receivable - net consists of freight and non-freight receivables, reduced by an allowance for credit losses. Freight receivables include amounts earned, billed and unbilled , and currently due from customers for transportation-related services. Non-freight receivables include amounts, billed and unbilled, currently due related to government reimbursement receivables and other non-revenue receivables.

(Dollars in Millions)	March 31, 2026	December 31, 2025
Freight Receivables	$ 1,070	$ 932
Freight Allowance for Credit Losses	( 21 )	( 23 )

Non-Freight Allowance for Credit Losses	( 17 )	( 15 )
Non-Freight Receivables - Net	338	389
Total Accounts Receivable - Net	$ 1,387	$ 1,298

The Company maintains an allowance for expected credit losses to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of risk characteristics, historical payment experience, and the age of outstanding receivables adjusted for forward-looking economic conditions as necessary. Credit losses recognized on the Company’s accounts receivable were not material in the first quarters ended March 31, 2026, or 2025.

NOTE 9. Fair Value Measurements

Investments

The Company's investment assets are carried at fair value on the consolidated balance sheet in accordance with the Fair Value Measurements and Disclosures Topic in the ASC. They are valued with assistance from a third-party trustee and consist of exchange-traded funds, corporate bonds, asset-backed securities, government securities, and short-term time deposits. The exchange-traded funds are valued at quoted market prices determined in an active market, which are Level 1 inputs.

The corporate bonds, asset-backed securities and government securities are valued using broker quotes that utilize observable market inputs, which are Level 2 inputs. The carrying amounts of time deposits, which are reported in the consolidated balance sheet using Level 2 inputs, approximate fair value due to their short-term nature. Unrealized losses as of March 31, 2026, and March 31, 2025, were not material. The Company believes any impairment of investments held with gross unrealized losses to be temporary and not the result of credit risk.

The Company's investment assets are carried at fair value on the consolidated balance sheets, within the line items short-term investments and other long-term assets, as summarized in the following table.

(Dollars in Millions)	March 31, 2026 — Level 1	Level 2	Total	Level 1	Level 2	Total
Exchange-traded Funds	$ 5	$ —	$ 5	$ 5	$ —	$ 5

Total Investments at Fair Value	$ 5	$ 298	$ 303	$ 5	$ 182	$ 187

Total investments in debt securities of $ 298 million as of March 31, 2026, and $ 182 million as of December 31, 2025, had an amortized cost of $ 299 million and $ 181 million, respectively. These investments have the following maturities:

(Dollars in Millions)	March 31, 2026	December 31, 2025
Less than 1 year	$ 145	$ 5

Total Investments at Fair Value (a)	$ 298	$ 182

(a) Exchange-traded funds are excluded as there is no stated contractual maturity date.

NOTE 9. Fair Value Measurements, continued

Long-term Debt

Long-term debt is reported at carrying amount on the consolidated balance sheets and is the Company's only financial instrument with a fair value significantly different from its carrying amount. The fair value of a company's debt is a measure of its current value under present market conditions, but does not impact the financial statements under current accounting rules. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.

The fair value and carrying value of the Company's long-term debt is as follows:

(Dollars in Millions)	March 31, 2026	December 31, 2025
Long-term Debt (Including Current Maturities):
Fair Value	$ 17,022	$ 17,305
Carrying Value	18,868	18,873

Interest Rate Derivatives

The Company’s fixed-to-floating swaps are carried at fair value, which is determined with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the fixed-to-floating interest rate swaps are Level 2 inputs. The fair value of the Company’s fixed-to-floating interest rate swaps was an asset of $ 19 million and $ 23 million (for swaps entered in 2025 and 2023), and a liability of $ 92 million and $ 87 million (for swaps entered in 2022) as of March 31, 2026, and December 31, 2025, respectively.

Changes in interest rates no longer impact the fair value of the Company’s forward starting interest rate swaps because they are fully settled. See Note 7, Debt and Credit Agreements, for further information.

NOTE 10. Other Comprehensive Income (Loss)

Total comprehensive earnings represents all changes in shareholders' equity during a period, other than those resulting from investments by and distributions to shareholders (e.g. issuance of equity securities and dividends). Generally, for CSX, total comprehensive earnings equals net earnings plus or minus adjustments for pension and other post-retirement liabilities, derivative activity and other items. Total comprehensive earnings is presented net of tax and was $ 808 million and $ 651 million for first quarters 2026 and 2025, respectively.

AOCI represents the cumulative balance of other comprehensive income, net of tax, as of the balance sheet date. Changes in the AOCI balance by component are shown in the following table. Amounts in pension and other post-employment benefits reclassified to net earnings relate to the amortization of actuarial losses and are included in other income - net on the consolidated income statements. See Note 6, Employee Benefit Plans , for further information. Interest rate derivatives consist of forward starting interest rate swaps classified as cash flow hedges, which are now fully settled. See Note 7, Debt and Credit Agreements , for further information. Other primarily represents CSX's share of AOCI of equity method investees. Amounts reclassified in other to net earnings are included in purchased services and other or equipment and other rents on the consolidated income statements.

NOTE 11. Segment Reporting and Significant Expenses

The Company has two operating segments : rail and trucking. Although the Company provides a breakdown of revenue by line of business, the overall financial and operational performance of the railroad is analyzed as one operating segment due to the integrated nature of the rail network. The Rail column in the table below includes the activities of all CSX entities other than the trucking company, Quality Carriers, and also includes the Company's equity in the net income of equity method investments. As the trucking segment is not material for separate disclosure as a reportable segment, the results of these operations are included as a reconciliation to the Company's consolidated results in the tables below.

The Company's chief operating decision maker ("CODM") is its CEO. The CODM reviews information presented on a consolidated basis, accompanied by supplemental information about the trucking segment separately, for purposes of allocating resources and evaluating financial performance. The Company has determined that operating income is the key measure of segment profit or loss as this measure is the focus of the CODM in developing financial plans, including resource allocation, and evaluating actual financial performance against plan. The CODM regularly reviews operating results broken out by significant expense.

NOTE 11. Segment Reporting and Significant Expenses, continued

The table below presents information about the Company's significant expenses and the required reportable segment reconciliations for the quarters ended March 31, 2026, and March 31, 2025.

(a) Trucking revenue is comprised of revenue from Quality Carriers. Rail revenue represents revenue attributed to all CSX entities other than the trucking company, Quality Carriers.

(b) Trucking expenses include labor and fringe, purchased services and other, depreciation and amortization, fuel, equipment and other rents, and gains/losses on property dispositions from the operations of Quality Carriers. Rail expenses represent expenses attributable to all CSX entities other than the trucking company, Quality Carriers.

NOTE 11. Segment Reporting and Significant Expenses, continued

Capital expenditures made by the rail segment were $ 537 million and $ 691 million, for the first quarters 2026 and 2025, respectively. The total of the rail segment's reportable assets was $ 44.1 billion and $ 43.5 billion as of March 31, 2026, and December 31, 2025, respectively, out of total consolidated assets of $ 44.2 billion and $ 43.7 billion for the respective periods. The remaining non-rail assets are comprised of assets held by the trucking operating segment.

First Quarter 2026

Revenue

Total revenue increased 2% in first quarter 2026 when compared to first quarter 2025 due to higher pricing in merchandise, volume growth in intermodal, higher domestic coal revenue, and increased fuel surcharge revenue. These increases were partially offset by a decrease in export coal revenue, including the impact of lower benchmark rates.

Merchandise Volume

Chemicals - Increased due to higher shipments of sand, petcoke, and waste, partially offset by lower shipments of crude oil.

Agricultural and Food Products - Increased due to higher shipments of feed ingredients and export grains, partially offset by decreased shipments of domestic feed grain, food and consumer products, and ethanol.

Automotive - Flat despite the impact of a temporary outage at a customer location associated with re-tooling efforts.

Minerals - Increased due to higher shipments of cement and salt.

Metals and Equipment - Flat as increased scrap and pipe shipments were offset by lower steel and aluminum shipments, which include the impact of customer plant closures.

Forest Products - Decreased due to lower shipments of pulp and paper products, which include the impacts of both customer plant closures and temporary outages, as well as lower shipments of building products.

Fertilizers - Increased due to higher short-haul phosphates shipments, partially offset by decreases in long-haul shipments.

Intermodal Volume

Domestic shipments increased due to wins with key customers and new service offerings. International shipments were relatively flat to prior year levels.

Coal Volume

Domestic coal increased due to higher shipments to utility plants, partially offset by lower shipments to river terminals. Export coal decreased due to lower shipments of metallurgical coal primarily as a result of weather impacts on the overall supply chain.

Trucking Revenue

Trucking revenue was flat to prior year results.

Other Revenue

Other revenue increased $1 million.

Expenses

Expenses of $2.2 billion decreased $153 million, or 6%, in first quarter 2026 when compared to the first quarter 2025.

Labor and Fringe expense decreased $9 million due to the following:

• Inflation increases of $41 million were almost entirely offset by efficiency savings, which were primarily driven by lower headcount.

• All other net costs decreased $10 million.

Purchased Services and Other expense decreased $158 million due to the following:

• Efficiency savings net of inflation were $50 million, driven by cost reductions across operating and support functions.

• Gains on property dispositions were $44 million in first quarter 2026 compared to no gains in the prior year.

• A decrease of $20 million was due to the effects of network disruptions and congestion in the prior year, which included higher locomotive usage costs and rerouting charges associated with the Howard Street Tunnel project.

• All other net costs decreased $44 million due to several non-significant items, roughly one-third of which relate to prior year costs that did not recur in the current year.

Depreciation and Amortization expense decreased $10 million primarily as a result of an equipment depreciation study.

Fuel costs increased $27 million primarily due to a 14% increase in locomotive fuel prices.

Equipment and Other Rents expense decreased $3 million.

Interest Expense

Interest expense increased $4 million primarily due to higher average debt balances.

Other Income - Net

Other income - net decreased $3 million primarily due to lower interest income.

Income Tax Expense

Income tax expense increased $44 million primarily due to higher earnings before income taxes.

Non-GAAP Measures - Unaudited

CSX reports its financial results in accordance with accounting principles generally accepted in the United States of America ("GAAP"). CSX also uses certain non-GAAP measures that fall within the meaning of Securities and Exchange Commission Regulation G and Regulation S-K Item 10(e), which may provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP measures do not have standardized definitions and are not defined by GAAP. Therefore, CSX’s non-GAAP measures are unlikely to be comparable to similar measures presented by other companies. The presentation of these non-GAAP measures should not be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP. Reconciliations of non-GAAP measures to corresponding GAAP measures are below.

Free Cash Flow

Management believes that Free Cash Flow ("FCF") is supplemental information useful to investors as it is important in evaluating the Company’s financial performance. More specifically, FCF measures cash generated by the business after reinvestment. This measure represents cash available for both equity and bond investors to be used for dividends, share repurchases or principal reduction on outstanding debt. FCF is calculated by using net cash from operations and adjusting for property additions and proceeds and advances from pr operty dispositions. FCF should be considered in addition to, rather than a substitute for, cash provided by operating activities.

The increase in FCF before dividends from the prior year of $234 million is primarily due to higher net earnings and decreased property additions, partially offset by unfavorable working capital activities. Prior year property additions include $133 million related to rebuilding the Blue Ridge subdivision, which was reopened in September 2025.

The following table reconciles cash provided by operating activities (GAAP measure) to FCF before dividends (non-GAAP measure).

(Dollars in Millions)	Three Months — 2026	2025
Net cash provided by operating activities	$ 1,272	$ 1,255
Property Additions	(543)	(719)
Proceeds and Advances from Property Dispositions	64	23
Free Cash Flow (before payment of dividends)	$ 793	$ 559

Operating Statistics (Estimated)

The Company is committed to continuous improvement in safety and service performance through training, innovation and investment. Training and safety programs are designed to prevent incidents that can adversely impact employees, customers and communities. Technological innovations that can detect and avoid many types of human factor incidents are designed to serve as an additional layer of protection for the Company's employees. Continued capital investment in the Company's assets, including track, bridges, signals, equipment and detection technology also supports safety performance.

In the first quarter of 2026, velocity and dwell both improved by 7% versus prior year. Carload trip plan performance improved by 7% and intermodal trip plan performance decreased by 2%. The Company continues to focus on operational improvements and executing the operating plan to deliver safe, reliable, and efficient service to customers.

The Federal Railroad Administration (“FRA”) personal injury frequency index of 0.81 in first quarter 2026 improved 13% compared to prior year and the FRA train accident rate of 2.44 improved 31%. Safety is a top priority at CSX, and the Company is committed to reducing risk and enhancing the overall safety of its employees, customers, and communities in which it operates.

Certain operating statistics are estimated and can continue to be updated as actuals settle. The methodology for calculating train velocity, dwell, cars online and trip plan performance differs from that used by the Surface Transportation Board. The Company will continue to report these metrics to the Surface Transportation Board using the prescribed methodology.

Key Performance Measures Definitions

Train Velocity - Average train speed between origin and destination in miles per hour (does not include locals, yard jobs, work trains or passenger trains). Train velocity measures actual train miles and times of a train movement on CSX's network.

Dwell - Average amount of time in hours between car arrival to and departure from the yard.

Cars Online - Average number of active freight rail cars on lines operated by CSX, excluding rail cars that are being repaired, in storage, those that have been sold, or private cars dwelling at a customer location more than one day.

On-Time Origina tions - Percent of scheduled road trains that depart the origin yard on-time or ahead of schedule.

On-Time Arrivals - Percent of scheduled road trains that arrive at the destination yard on-time to within two hours of scheduled arrival.

Carload Trip Plan Performance - Percent of measured cars (excludes unit trains and other non-scheduled service as well as empty automotive shipments) destined for a customer that complete their scheduled plan at or ahead of the original estimated time of arrival or interchange (as applicable).

Intermodal Trip Plan Performance - Percent of measured containers (excludes port shipments along with empty containers and other non-scheduled service) destined for a customer that complete their scheduled plan at or ahead of the original estimated time of arrival, notification or interchange (as applicab le).

Fuel Efficiency - Gallons of locomotive fuel per 1,000 gross ton-miles.

Revenue Ton-Miles (RTM's) - The movement of one revenue-producing ton of freight over a distance of one mile.

Gross Ton-Miles (GTM's) - The movement of one ton of train weight over one mile. GTM's are calculated by multiplying total train weight by distance the train moved. Total train weight is comprised of the weight of the freight cars and their contents.

FRA Personal Injury Frequency Index - Number of FRA-reportable injuries per 200,000 man-hours.

FRA Train Accident Rate - Number of FRA-reportable train accidents per million train-miles.

LIQUIDITY AND CAPITAL RESOURCES

The following are material changes in the significant cash flows, sources of cash and liquidity, capital investments, consolidated balance sheets and working capital, which provide an update to the discussion included in CSX's most recent annual report on Form 10-K.

Material Changes in Significant Cash Flows

The following chart highlights the operating, investing and financing components of the net increases of $294 million and $206 million in cash and cash equivalents for the three months ended March 31, 2026, and March 31, 2025, respectively.

• The Company generated $17 million more cash from operating activities primarily resulting from higher cash-generating net earnings, mostly offset by unfavorable working capital activity.

• CSX used $80 million less cash for investing activities primarily due to lower property additions consistent with planned capital expenditures, as prior year included $133 million related to rebuilding the Blue Ridge subdivision. Partially offsetting this decrease, the Company purchased short-term investments in 2026.

• The Company used $9 million more cash for financing activities as reduced cash from debt issuance was mostly offset by lower share repurchases.

Sources of Cash and Liquidity and Uses of Cash

As of the end of first quarter 2026, CSX had $1.1 billion of cash, cash equivalents and short-term investments. CSX uses current cash balances for general corporate purposes, which may include capital expenditures, working capital requirements, reduction or refinancing of outstanding indebtedness, redemptions and repurchases of CSX common stock, dividends to shareholders, acquisitions and other business opportunities, and contributions to the Company's qualified pension plan. See Note 7, Debt and Credit Agreements .

The Company has multiple sources of liquidity, including cash generated from operations and financing sources. The Company filed a shelf registration statement with the SEC on February 27, 2025, which may be used to issue debt or equity securities at CSX’s discretion, subject to market conditions and CSX Board authorization. While CSX seeks to give itself flexibility with respect to cash requirements, there can be no assurance that market conditions would permit CSX to sell such securities on acceptable terms at any given time, or at all. During the three months ended March 31, 2026, CSX did not issue any long-term debt.

CSX has a $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks that expires in February 2028. At March 31, 2026, the Company had no outstanding balances under this facility. The Company also has a commercial paper program, backed by the revolving credit facility, under which the Company may issue unsecured short-term commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any time. At March 31, 2026, the Company had no debt outstanding under the commercial paper program.

Planned capital investments for 2026 are expected to be less than $2.4 billion. Spending to sustain core infrastructure with a focus on safety and reliability will remain a top priority. In addition, management is committed to investments that promote profitable growth, including projects supporting service enhancements and productivity initiatives, which includes investments in locomotives and freight cars. CSX intends to fund capital investments primarily through cash generated from operations.

Material Changes in the Consolidated Balance Sheets and Working Capital

Total assets increased $550 million from year end primarily due to the $434 million increase in cash and short-term investments and an $89 million increase in accounts receivable commensurate with increased revenue at the end of the quarter.

Total liabilities increased $129 million from year end primarily due to a $176 million increase in income and other taxes payable and a $73 million increase in interest payable on long-term debt, both driven by the timing of payments. These increases were partially offset by a $118 million decrease in labor and fringe benefits payable, which includes the payout of incentive compensation. Total shareholders' equity increased $421 million from year end primarily driven by net earnings of $807 million, partially offset by dividends paid of $260 million and share repurchases of $222 million.

Working capital is considered a measure of a company's ability to meet its short-term needs. CSX had a working capital deficit of $110 million as of March 31, 2026, and $583 million as of December 31, 2025. This working capital improvement of $473 million since year end was primarily driven by a $294 million increase in cash and cash equivalents, as noted above, and a $140 million increase in short-term investments. The Company's working capital balance varies due to factors such as the timing of scheduled debt payments and changes in cash and cash equivalent balances as discussed above. The Company continues to maintain adequate liquidity to satisfy current liabilities and maturing obligations when they come due. CSX has sufficient financial capacity, including its revolving credit facility, commercial paper program and shelf registration statement to manage its day-to-day cash requirements and any anticipated obligations. The Company from time to time accesses the credit markets for additional liquidity.

CSX is committed to returning cash to shareholders and maintaining an investment-grade credit profile. Capital structure, capital investments and cash distributions, including dividends and share repurchases, are reviewed at least annually by the Board of Directors. Management's assessment of market conditions and other factors guides the timing and volume of repurchases. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances.

This discussion should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes that appear elsewhere in this document.

LABOR AGREEMENTS

Approximately 16,700 of the Company's approximately 22,200 employees are members of a rail labor union and covered by national agreements with the Class I railroads or CSX-specific agreements. Agreements with an effective date of January 1, 2025, have been fully ratified by most unions, representing nearly 75% of the Company's unionized workforce. The remaining unionized employees are covered under previous agreements while negotiations take place since collective agreements under the Railway Labor Act do not expire, but continue until amended or replaced.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in reporting the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and certain revenues and expenses during the reporting period. Actual results may differ from those estimates. These estimates and assumptions are discussed with the Audit Committee of the Board of Directors on a regular basis. Consistent with the prior year, significant estimates using management judgment are made for the areas below. For further discussion of CSX's critical accounting estimates, see the Company's most recent annual report on Form 10-K.

• personal injury and environmental reserves;

• pension plan accounting; and

• depreciation policies for assets under the group-life method.

FORWARD-LOOKING STATEMENTS

Certain statements in this report and in other materials filed with the Securities and Exchange Commission, as well as information included in oral statements or other written statements made by the Company, are forward-looking statements. The Company intends for all such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and the provisions of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements within the meaning of the Private Securities Litigation Reform Act may contain, among others, statements regarding:

• projections and estimates of earnings, revenues, margins, volumes, rates, cost-savings, expenses, taxes or other financial items;

• expectations as to results of operations and operational initiatives;

• expectations as to the effect of claims, lawsuits, environmental costs, commitments, contingent liabilities, labor negotiations or agreements on the Company's financial condition, results of operations or liquidity;

• management's plans, strategies and objectives for future operations, capital expenditures, workforce levels, dividends, share repurchases, safety and service performance, proposed new services and other matters that are not historical facts, and management's expectations as to future performance and operations and the time by which objectives will be achieved; and

• future economic, industry or market conditions or performance and their effect on the Company's financial condition, results of operations or liquidity.

Forward-looking statements are typically identified by words or phrases such as “will,” “should,” “believe,” “expect,” “anticipate,” “project,” “estimate,” “preliminary” and similar expressions. The Company cautions against placing undue reliance on forward-looking statements, which reflect its good faith beliefs with respect to future events and are based on information currently available to it as of the date the forward-looking statement is made. Forward-looking statements should not be read as a guarantee of future performance or results and will not necessarily be accurate indications of the timing when, or by which, such performance or results will be achieved.

Forward-looking statements are subject to a number of risks and uncertainties and actual performance or results could differ materially from those anticipated by any forward-looking statements. The Company undertakes no obligation to update or revise any forward-looking statement. If the Company does update any forward-looking statement, no inference should be drawn that the Company will make additional updates with respect to that statement or any other forward-looking statements. The following important factors, in addition to those discussed in Part I, Item 1A. Risk Factors of CSX's most recent annual report on Form 10-K and elsewhere in this report, may cause actual results to differ materially from those contemplated by any forward-looking statements:

• legislative, regulatory or legal developments involving transportation, including rail or intermodal transportation, the environment, hazardous materials, taxation, international trade and initiatives to further regulate the rail industry;

• the outcome of litigation, claims and other contingent liabilities, including, but not limited to, those related to fuel surcharge, environmental matters, taxes, shipper and rate claims subject to adjudication, personal injuries and occupational illnesses;

• changes in domestic or international economic, political or business conditions, including those directly affecting the transportation industry (such as the impact of industry competition, conditions, performance and consolidation, as well as the impact of international trade agreements and tariffs) and those affecting the level of demand for products carried by CSXT or by truck, which could impact the performance and value of the Company's rail and trucking-related investments;

• natural events such as severe weather conditions, including floods, fire, hurricanes and earthquakes, a pandemic crisis affecting the health of the Company's employees, its shippers or the consumers of goods, or other unforeseen disruptions of the Company's operations, systems, property, equipment or supply chain;

• competition from other modes of freight transportation, such as trucking, and competition and consolidation or financial distress within the transportation industry generally;

• the cost of compliance with laws and regulations that differ from expectations as well as costs, penalties and operational and liquidity impacts associated with noncompliance with applicable laws or regulations;

• the impact of increased passenger activities in capacity-constrained areas, including potential effects of high speed rail initiatives, or regulatory changes affecting when CSXT can transport freight or service routes;

• unanticipated conditions in the financial markets that may affect timely access to capital markets and the cost of capital, as well as management's decisions regarding share repurchases;

• changes in fuel prices, surcharges for fuel and the availability of fuel;

• the impact of natural gas prices on coal-fired electricity generation;

• the impact of global supply and price of seaborne coal on CSX's export coal market;

• availability of insurance coverage at commercially reasonable rates or insufficient insurance coverage to cover claims or damages;

• the inherent business risks associated with safety and security, including the transportation of hazardous materials or a cybersecurity attack which would threaten the availability and reliability of information technology;

• adverse economic or operational effects from actual or threatened war or terrorist activities and any governmental response;

• loss of key personnel or the inability to hire and retain qualified employees;

• labor and benefit costs and labor difficulties, including stoppages affecting either the Company's operations or customers' ability to deliver goods to the Company for shipment;

• the Company's success in implementing its strategic, financial and operational initiatives, including acquisitions;

• the impact of conditions in the real estate market on the Company's ability to sell assets;

• changes in operating conditions and costs, including the impacts of inflation, or commodity concentrations;

• the impacts of a public health crisis and any policies or initiatives instituted in response; and

• the inherent uncertainty associated with projecting economic and business conditions.

Other important assumptions and factors that could cause actual results to differ materially from those in the forward-looking statements are specified elsewhere in this report and in CSX's other SEC reports, which are accessible on the SEC's website at www.sec.gov and the Company's website at www.csx.com . The information on the CSX website is not part of this quarterly report on Form 10-Q.
