NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1.Accounting Policies and Interim Results

The Consolidated Financial Statements should be read in conjunction with Burlington Northern Santa Fe, LLC’s Annual Report on Form 10-K for the year ended December 31, 2024, including the financial statements and notes thereto. Burlington Northern Santa Fe, LLC (Registrant) is a holding company that conducts no operating activities and owns no significant assets other than through its interests in its subsidiaries. The Consolidated Financial Statements include the accounts of the Registrant and its subsidiaries (collectively, BNSF or Company), all of which are separate legal entities. The Registrant’s principal operating subsidiary is BNSF Railway Company (BNSF Railway). All intercompany accounts and transactions have been eliminated.

On February 12, 2010, Berkshire Hathaway Inc., a Delaware corporation (Berkshire), acquired 100 percent of the outstanding shares of Burlington Northern Santa Fe Corporation common stock that it did not already own. The acquisition was completed through the merger of a Berkshire wholly-owned merger subsidiary and Burlington Northern Santa Fe Corporation with the surviving entity renamed Burlington Northern Santa Fe, LLC. Earnings per share data is not presented because BNSF has only one holder of its membership interests.

The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the entire year. In the opinion of management, the unaudited financial statements reflect all adjustments (consisting of only normal recurring adjustments, except as disclosed) necessary for the fair statement of BNSF’s consolidated financial position as of March 31, 2025, and the results of operations for the three months ended March 31, 2025 and 2024 in accordance with generally accepted accounting principles in the United States.

2.Segment Information

The Registrant's principal wholly-owned subsidiary is BNSF Railway and represents its only operating segment. The financial results are evaluated as one reportable segment due to the integrated nature of the Company's rail network. See Note 1 to the Consolidated Financial Statements of the Company's Annual Report on Form 10-K for information related to the subsidiary's services offered and business operations. As BNSF Railway's operations are not materially different from the Company's, the Chief Executive Officer, who acts as the chief operating decision maker (CODM), assesses the segment at the consolidated level. The CODM uses the Company's consolidated net income to evaluate the overall profitability of the segment and allocate resources across the Company's rail network. Consolidated net income is benchmarked against forecasted targets, historical results, and industry standards and analyzed for trends for organizational strategic planning purposes. BNSF Railway's assets and significant expenses are also reviewed at the consolidated level. See the Consolidated Financial Statements for more information. Additionally, while BNSF Railway operates outside of the U.S., its foreign operations are immaterial to the reportable segment.

3.Revenue from Contracts with Customers

The Company disaggregates revenue from contracts with customers based on the characteristics of the services provided and the types of products transported (in millions):

	Three Months Ended March 31,
	2025		2024
Consumer Products	$	2,033	$	1,970
Agricultural and Energy Products a	1,565		1,552
Industrial Products a	1,199		1,240
Coal	734		765
Total freight revenues	5,531		5,527
Non-rail logistics subsidiary	18		16
Accessorial and other	144		117
Total other revenues	162		133
Total operating revenues	$	5,693	$	5,660

a Prior year numbers have been recast to conform to the current year presentation based on internal reorganization of business groups.

BURLINGTON NORTHERN SANTA FE, LLC and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) - (Continued)

Contract assets and liabilities are immaterial. Receivables from contracts with customers is a component of accounts receivable, net on the Consolidated Balance Sheets. As of March 31, 2025 and December 31, 2024, $1.2 billion and $1.1 billion, respectively, represented net receivables from contracts with customers.

Remaining performance obligations primarily consist of in-transit freight revenues, which will be recognized in the next reporting period. As of March 31, 2025 and December 31, 2024, remaining performance obligations were $294 million and $308 million, respectively.

4.Accounts Receivable, Net

Accounts receivable, net consists of freight and other receivables, reduced by an allowance for credit losses which is based upon expected collectability. As of March 31, 2025 and December 31, 2024, $41 million and $40 million, respectively, of such allowances had been recorded.

5.Debt

Notes and Debentures

As of March 31, 2025, $1.65 billion remained authorized by the Board of Directors to be issued through the debt shelf offering process.

The Registrant is required to maintain certain financial covenants in conjunction with $500 million of certain issued and outstanding junior subordinated notes. As of March 31, 2025, the Registrant was in compliance with these financial covenants.

Fair Value of Debt Instruments

As of March 31, 2025 and December 31, 2024, the fair value of BNSF’s debt, excluding finance leases, was $21.4 billion and $21.1 billion, respectively, while the book value as of both March 31, 2025 and December 31, 2024, which also excludes finance leases, was $23.4 billion. The fair value of BNSF’s debt is primarily based on market value price models using observable market-based data for the same or similar issues, or on the estimated rates that would be offered to BNSF for debt of the same remaining maturities (Level 2 inputs).

6.Commitments and Contingencies

Personal Injury

BNSF’s personal injury liability includes the cost of claims for employee work-related injuries, third-party claims, and asbestos claims. BNSF records a liability for asserted and unasserted claims when the expected loss is both probable and reasonably estimable. Because of the uncertainty of the timing of future payments, the liability is undiscounted. Defense and processing costs, which are recorded on an as-reported basis, are not included in the recorded liability. Expense accruals and adjustments are classified as materials and other in the Consolidated Statements of Income.

Personal injury claims by BNSF Railway employees are subject to the provisions of the Federal Employers’ Liability Act (FELA) rather than state workers’ compensation laws. Resolution of these cases under FELA’s fault-based system requires either a finding of fault by a jury or an out of court settlement. Third-party claims include claims by non-employees for compensatory damages and may, from time to time, include requests for punitive damages or treatment of the claim as a class action.

BNSF estimates its personal injury liability claims and expense using standard actuarial methodologies based on the covered population, activity levels and trends in frequency, and the costs of covered injuries. The Company monitors actual experience against the forecasted number of claims to be received, the forecasted number of claims closing with payment, and expected claim payments and records adjustments as new events or changes in estimates develop.

BURLINGTON NORTHERN SANTA FE, LLC and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) - (Continued)

The following table summarizes the activity in the Company’s accrued obligations for personal injury claims (in millions):

	Three Months Ended March 31,
	2025		2024
Beginning balance	$	265	$	264
Accruals / changes in estimates	9		26
Payments	(35)		(28)
Ending balance	$	239	$	262
Current portion of ending balance	$	85	$	85

The amount recorded by the Company for the personal injury liability is based upon the best information currently available. Because of the uncertainty surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to resolve these claims may be different from the recorded amounts. The Company estimates that costs to resolve the liability may range from approximately $195 million to $310 million.

Although the final outcome of these personal injury matters cannot be predicted with certainty, it is the opinion of BNSF that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Environmental

BNSF is subject to extensive federal, state, and local environmental regulation. The Company’s operating procedures include practices to protect the environment from the risks inherent in railroad operations, which often involve transporting chemicals and other hazardous materials. Additionally, many of BNSF’s land holdings are or have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities may have resulted in discharges onto the property. Under federal (in particular, the Comprehensive Environmental Response, Compensation, and Liability Act) and state statutes, the Company may be held jointly and severally liable for cleanup and enforcement costs associated with a particular site without regard to fault or the legality of the original conduct. The Company participates in the study, cleanup, or both of environmental contamination at approximately 185 sites.

Environmental costs may include, but are not limited to, site investigations, remediation, and restoration. The liability is recorded when the expected loss is both probable and reasonably estimable and is undiscounted due to uncertainty of the timing of future payments. Expense accruals and adjustments are classified as materials and other in the Consolidated Statements of Income.

BNSF estimates the cost of cleanup efforts at its known environmental sites based on experience gained from cleanup efforts at similar sites, estimated percentage to closure ratios, possible remediation work plans, estimates of the costs and likelihood of each possible outcome, historical payment patterns, and benchmark patterns developed from data accumulated from industry and public sources. The Company monitors actual experience against expectations and records adjustments as new events or changes in estimates develop.

The following table summarizes the activity in the Company’s accrued obligations for environmental matters (in millions):

	Three Months Ended March 31,
	2025		2024
Beginning balance	$	224	$	236
Accruals / changes in estimates	1		—
Payments	(3)		(4)
Ending balance	$	222	$	232
Current portion of ending balance	$	35	$	35

BURLINGTON NORTHERN SANTA FE, LLC and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) - (Continued)

The amount recorded by the Company for the environmental liability is based upon the best information currently available. It has not been reduced by anticipated recoveries from third parties and includes both asserted and unasserted claims. BNSF’s total cleanup costs at these sites cannot be predicted with certainty due to various factors, such as the extent of corrective actions that may be required, evolving environmental laws and regulations, advances in environmental technology, the extent of other parties’ participation in cleanup efforts, developments in ongoing environmental analyses related to sites determined to be contaminated, and developments in environmental surveys and studies of contaminated sites. Because of the uncertainty surrounding various factors, it is reasonably possible that future costs to settle these claims may be different from the recorded amounts. The Company estimates that costs to settle the liability may range from approximately $200 million to $260 million.

Although the final outcome of these environmental matters cannot be predicted with certainty, it is the opinion of BNSF that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Other Claims and Litigation

In addition to personal injury and environmental matters, BNSF is a party to a number of other legal actions and claims, governmental proceedings, and private civil suits arising in the ordinary course of business, including those related to disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory damages and may, from time to time, include requests for punitive damages or treatment of the claim as a class action. Although the final outcome of these matters cannot be predicted with certainty, it is the opinion of BNSF that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

On April 7, 2015, the Swinomish Indian Tribal Community (the Tribe) filed a legal case against BNSF Railway alleging that it breached an easement over the Tribe's reservation. On June 17, 2024, a judgment was entered against BNSF Railway in the amount of $395 million, which it has appealed. While the ultimate resolution of this matter is subject to further developments, the Company does not believe that the outcome will have a material adverse effect on its financial position, results of operations or liquidity.

BNSF Insurance Company

BNSF has a consolidated, wholly-owned subsidiary, Burlington Northern Santa Fe Insurance Company, Ltd. (BNSFIC), that offers insurance coverage for certain risks including FELA, railroad protective and force account insurance, and property and excess general liability which are subject to reinsurance. BNSFIC has entered into annual reinsurance treaty agreements with several other companies. The treaty agreements insure workers’ compensation, general liability, auto liability, and FELA risk. In accordance with the agreements, BNSFIC cedes a portion of its FELA exposure through the treaties and assumes a proportionate share of the entire risk. Each year, BNSFIC reviews the objectives and performance of the treaties to determine its continued participation. The treaty agreements provide for certain protections against the risk of treaty participants’ non-performance. On an ongoing basis, BNSF and/or the treaty manager reviews the creditworthiness of each of the participants. The Company does not believe its exposure to treaty participants’ non-performance is material at this time. BNSFIC typically invests in time deposits, money market accounts, and treasury bills. As of March 31, 2025 and December 31, 2024, there was $563 million and $562 million, respectively, related to these third-party investments, which were classified as cash and cash equivalents on the Company’s Consolidated Balance Sheets.

7.Employment Benefit Plans

The Registrant provides a funded, noncontributory qualified pension plan (BNSF Retirement Plan), which covered most non-union employees through March 31, 2019, and an unfunded non-tax-qualified pension plan (BNSF Supplemental Retirement Plan), which covered certain officers and other employees through March 31, 2019. The benefits under these pension plans are based on years of credited service and the highest consecutive sixty months of compensation for the last ten years of salaried employment with the Company. In 2019, the Registrant amended the BNSF Retirement Plan and the BNSF Supplemental Retirement Plan. Non-union employees hired on or after April 1, 2019 are not eligible to participate in these retirement plans and instead receive an additional employer contribution as part of the qualified 401(k) plan based on the employees’ age and years of service. Current plan participants are being transitioned away from the retirement plans and upon transition are eligible for the additional employer contribution.

BNSF Railway also provides a funded, noncontributory qualified pension plan which covers certain union employees of the former The Atchison, Topeka and Santa Fe Railway Company (Union Plan). The benefits under this pension plan are based on elections made at the time the plan was implemented.

With respect to the funded plans, the Registrant's funding policy is to contribute annually not less than the regulatory minimum and not more than the maximum amount deductible for income tax purposes. The BNSF Retirement Plan, the BNSF Supplemental Retirement Plan, and the Union Plan are collectively referred to herein as the Pension Plans.

Components of the net (benefit) cost for the Pension Plans were as follows (in millions):

	Pension Benefits
	Three Months Ended March 31,
	2025		2024
Service cost	$	2	$	3
Interest cost	21		21
Expected return on plan assets	(48)		(47)
Amortization of net (gain) loss	(7)		(5)
Net (benefit) cost recognized	$	(32)	$	(28)

Service cost is included in compensation and benefits expense and the other components of net periodic benefit costs are included in other (income) expense, net in the Consolidated Statements of Income.

8.Related Party Transactions

The companies identified as affiliates of BNSF include Berkshire and its subsidiaries. During the three-months ended March 31, 2025 and 2024, the Company declared and paid cash distributions of $700 million and $500 million, respectively, to Berkshire. In both of the three-month periods ended March 31, 2025 and 2024, the Company made no tax payments and received no tax refunds from Berkshire. As of March 31, 2025 and December 31, 2024, the Company had a tax payable to Berkshire of $403 million and a payable to Berkshire of $86 million, respectively.

North American railroads pay TTX Company (TTX) car hire to use TTX’s freight equipment to serve their customers. BNSF owns 17.4 percent of TTX while other North American railroads own the remaining interest. As the Company possesses the ability to exercise significant influence, but not control, over the operating and financial policies of TTX, BNSF applies the equity method of accounting to its investment. The investment in TTX is recorded in other assets in the Consolidated Balance Sheets, and equity income or losses are recorded in materials and other in the Consolidated Statements of Income. The Company’s investment in TTX was $902 million and $891 million as of March 31, 2025 and December 31, 2024, respectively. The Company incurred car hire expenditures with TTX of $106 million and $97 million for the three-months ended March 31, 2025 and 2024, respectively.

9.Accumulated Other Comprehensive Income

Other comprehensive income refers to revenues, expenses, gains, and losses that under generally accepted accounting principles are included in accumulated other comprehensive income, a component of equity within the Consolidated Balance Sheets, rather than net income on the Consolidated Statements of Income. Under existing accounting standards, other comprehensive income may include, among other things, unrecognized gains and losses and prior service credit related to pension and other postretirement benefit plans.

The following table provides the components of accumulated other comprehensive income (loss) (AOCI) by component (in millions):

	Pension and Retiree Health and Welfare Benefit Items		Equity Method Investments		Accumulated Other Comprehensive Income (Loss)

Fuel Surcharges

Freight revenues include both revenue for transportation services and fuel surcharges. Where BNSF’s fuel surcharge program is applied, it is intended to recover BNSF’s incremental fuel costs when fuel prices exceed a threshold fuel price. Fuel surcharges are calculated differently depending on the type of commodity transported. BNSF has two standard fuel surcharge programs – Percent of Revenue and Mileage-Based. In addition, in certain commodities, fuel surcharge is calculated using a fuel price from a time period that can be up to 60 days earlier. In a period of volatile fuel prices or changing customer business mix, changes in fuel expense and fuel surcharge may differ significantly.

The following table presents fuel surcharge and fuel expense information (in millions):

    Three Months Ended March 31, 2025 vs. Three Months Ended March 31, 2024

Revenues

Revenues for the three months ended March 31, 2025 were $5.7 billion, an increase of $33 million, or 1 percent, as compared with the three months ended March 31, 2024. This was primarily due to a 4 percent increase in unit volume and core pricing gains, partially offset by a decrease in average revenue per car / unit resulting from lower fuel surcharge revenue and unfavorable business mix. Revenue amounts also included the following changes between periods:

▪Consumer Products volumes increased primarily due to higher intermodal shipments resulting from higher west coast imports and an increase in automotive volume from higher vehicle production.

▪Agricultural and Energy Products volumes decreased slightly due to lower volumes of domestic grains.

▪Industrial Products volumes decreased primarily due to weather related impacts and lower demand for construction and building products.

▪Coal volumes increased primarily due to increased demand from higher natural gas prices.

Expenses

Operating expenses for the three months ended March 31, 2025 were $3.9 billion, a decrease of $67 million, or 2 percent, as compared with the three months ended March 31, 2024. A significant portion of this decrease is due to the following changes in expenses:

▪Fuel expense decreased primarily due to lower average fuel prices, partially offset by higher volumes.

▪Compensation and benefits expense decreased primarily due to increased employee productivity, partially offset by wage inflation.

▪Purchased services expense increased primarily due to higher volume related costs, cargo security investments, and general inflation.

▪There were no significant changes in materials and other expense, equipment rent expense, or depreciation and amortization expense.

The effective tax rate was 24.3 percent and 24.8 percent for the three months ended March 31, 2025 and 2024, respectively.

Forward-Looking Information

To the extent that statements relate to the Company’s future economic performance or business outlook, projections or expectations of financial or operational results, or refer to matters that are not historical facts, such statements are “forward-looking” statements within the meaning of the federal securities laws.

Forward-looking statements involve a number of risks and uncertainties, and actual performance or results may differ materially. For a discussion of material risks and uncertainties that the Company faces, see the discussion in "Part I, Item 1A. Risk Factors" of the Company's Annual Report on Form 10-K for the year ended December 31, 2024. Important factors that could cause actual results to differ materially include, but are not limited to, the following:

•  Economic and industry conditions: material adverse changes in economic or industry conditions, both in the United States and globally; inflation; volatility in the capital or credit markets including changes affecting the timely availability and cost of capital; changes in customer demand; effects of adverse economic conditions affecting shippers or BNSF’s supplier base; effects due to more stringent regulatory policies such as the regulation of greenhouse gas emissions that could reduce the demand for coal or governmental tariffs or subsidies that could affect the demand for products BNSF hauls; the impact of low natural gas or oil prices on energy-related commodities demand; changes in environmental laws and other laws and regulations that could affect the demand for drilling products and products produced by drilling; changes in prices of fuel and other key materials, the impact of high barriers to entry for prospective new suppliers, and disruptions in supply chains for these materials; competition and consolidation within the transportation industry; and changes in crew availability, labor and benefits costs and labor difficulties, including stoppages affecting either BNSF’s operations or customers’ abilities to deliver goods to BNSF for shipment.

•   Legal, legislative and regulatory factors: developments and changes in laws and regulations, including those affecting train operations, the marketing of services or regulatory restrictions on equipment; the ultimate outcome of shipper and rate claims subject to adjudication; claims, investigations, or litigation alleging violations of the antitrust laws; increased economic regulation of the rail industry through legislative action and revised rules and standards applied by the STB in various areas including rates and services; developments in environmental investigations or proceedings with respect to rail operations or current or past ownership or control of real property or properties owned by others impacted by BNSF operations; losses resulting from claims and litigation relating to personal injuries, asbestos, and other occupational diseases; the release of hazardous materials, environmental contamination, and damage to property; regulation, restrictions or caps, or other controls on transportation of energy-related commodities or other operating restrictions that could affect operations or increase costs; the availability of adequate insurance to cover the risks associated with operations; and changes in tax rates and tax laws.

•   Operating factors: changes in operating conditions and costs; operational and other difficulties with positive train control technology, including increased compliance or operational costs or penalties; restrictions on development and expansion plans due to environmental concerns; disruptions to BNSF’s or third-party service providers' technology networks including computer systems and software, such as cybersecurity intrusions, unauthorized access to or misappropriation of assets or sensitive information, corruption of data or operational disruptions; network congestion, including effects of greater than anticipated demand for transportation services and equipment; as well as pandemics or natural events such as severe weather, fires, floods, and earthquakes or man-made or other disruptions of BNSF’s or other railroads’ operating systems, structures, or equipment including the effects of acts of war or terrorism on the Company’s system or other railroads’ systems or other links in the transportation chain.
