Exhibit 99.1

CSX Corp. Announces First Quarter 2026 Results

JACKSONVILLE, Fla. – April 22, 2026 – CSX Corp. (NASDAQ: CSX) today announced first quarter 2026 operating income of $1.25 billion and net earnings of $807 million, or $0.43 per diluted share. In the first quarter of 2025, the company reported operating income of $1.04 billion and net earnings of $646 million, or $0.34 per diluted share.

Total volume of 1.56 million units for the quarter was 3% higher compared to first quarter 2025. Revenue totaled $3.48 billion for the quarter, increasing 2% year-over-year, as higher merchandise pricing, intermodal volume growth, higher domestic coal revenue, and increased fuel surcharge revenue were partially offset by a decrease in export coal revenue, including the impact of lower benchmark rates.

“CSX performed well this quarter by providing reliable and efficient service to our customers through changing market conditions, while improving our expense profile,” said Steve Angel, president and chief executive officer. “As we remain disciplined on costs and take advantage of opportunities for profitable growth, we continue to make progress toward best-in-class performance. I am encouraged by our railroad’s prospects for this year and over the long term.”

CSX executives will conduct a conference call with the investment community this afternoon, April 22, at 4:30 p.m. Eastern Time. Investors, media and the public may listen to the conference call by dialing 1-888-510-2008. For callers outside the U.S., dial 1-646-960-0306. Participants should dial in 10 minutes prior to the call and enter in 3368220 as the passcode.

In conjunction with the call, a live webcast will be accessible and presentation materials will be posted on the company’s website at investors.csx.com. Following the earnings call, a webcast replay of the presentation will be archived on the company website.

This earnings announcement, as well as additional detailed financial information, is contained in the CSX Quarterly Financial Report available through the company’s website at investors.csx.com and on Form 8-K with the Securities and Exchange Commission.

This announcement, as well as additional financial information, is available on the company's website at investors.csx.com. CSX also uses social media channels to communicate information about the company. Although social media channels are not intended to be the primary method of disclosure for material information, it is possible that certain information CSX posts on social media could be deemed to be material. Therefore, we encourage investors, the media, and others interested in the company to review the information we post on X, formerly known as Twitter, (x.com/CSX) and on Facebook (facebook.com/OfficialCSX).

Non-GAAP Disclosure

CSX reports its financial results in accordance with accounting principles generally accepted in the United States of America (U.S. 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 U.S. 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.

Forward-looking statements are subject to a number of risks and uncertainties, and actual performance or results could differ materially from that anticipated by any forward-looking statements. Factors that may cause actual results to differ materially from those contemplated by any forward-looking statements include, among others: (i) the company's success in implementing its financial and operational initiatives; (ii) changes in domestic or international economic, political or business conditions, including those affecting the transportation industry (such as the impact of industry competition, conditions, performance and consolidation); (iii) legislative or regulatory changes; (iv) the inherent business risks associated with safety and security; (v) the outcome of claims and litigation involving or affecting the company; (vi) natural events such as severe weather conditions or pandemic health crises; (vii) changes in fuel prices, surcharges for fuel and the availability of fuel; (viii) adverse economic or operational effects from actual or threatened war or terrorist activities and any government response; and (ix) the inherent uncertainty associated with projecting economic and business conditions.

VOLUME AND 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.

Fuel Surcharge

Fuel surcharge revenue is included in the individual markets and does not include amounts for trucking. Fuel lag is the estimated revenue effect resulting from the difference between highway diesel prices in the quarter and the prices used for fuel surcharge, which are on a two-month lag for non-intermodal traffic.

Fuel Surcharge Revenue $ 231 $ 217

Fuel Lag (Unfavorable) Favorable $ (39) $ (5)

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.

EXPENSE

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

OPERATING STATISTICS (Estimated), continued

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 Originations - 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 applicable).

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.

CSX Corporation

NON-GAAP MEASURES (Unaudited)

The Company reports its financial results in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The Company 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, the Company’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 property dispositions. FCF should be considered in addition to, rather than a substitute for, cash provided by operating activities.

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