Exhibit 99.1

CSX Corp. Announces Second Quarter 2026 Results

•Record quarterly revenue of $3.94 billion, up 10% year-over-year; diluted EPS of $0.54, up 23%

•Operating income of $1.51 billion, up 17%; operating margin expanded 240 bps to 38.3%

•Volume increased 6% with broad-based growth across markets led by 9% intermodal growth

JACKSONVILLE, Fla. – July 22, 2026 – CSX Corp. (NASDAQ: CSX) today announced second quarter 2026 operating income of $1.51 billion and net earnings of $1.00 billion, or $0.54 per diluted share. In the second quarter of 2025, the company reported operating income of $1.28 billion and net earnings of $829 million, or $0.44 per diluted share. On a year-over-year basis, operating income increased 17%, net earnings increased 21%, and EPS increased 23%.

Total volume of 1.68 million units for the quarter was 6% higher compared to second quarter 2025. Revenue totaled $3.94 billion for the quarter, increasing 10% year-over-year, due to increased fuel surcharge revenue together with higher volume and pricing across merchandise, intermodal, and coal.

“Our second quarter results reflect the solid progress we’re making at CSX. Our railroaders successfully managed substantial volume growth while maintaining a consistent focus on safety and productivity, which allowed us to deliver improved financial performance,” said Steve Angel, president and chief executive officer. “As we move into the second half of the year, we will strengthen our service execution as we continue to build momentum across the business.”

CSX executives will conduct a conference call with the investment community this afternoon, July 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.

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.

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.

VOLUME AND REVENUE

Total revenue increased 10% in second quarter 2026 when compared to second quarter 2025 primarily due to increased fuel surcharge revenue together with higher volume and pricing across merchandise, intermodal and coal.

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 $ 410 $ 222 $ 641 $ 439

Fuel Lag (Unfavorable) Favorable $ (54) $ 4 $ (93) $ (1)

Merchandise Volume

Chemicals - Increased due to higher shipments of plastics, waste, petcoke and sand.

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

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

Automotive - Decreased due to the impact of a temporary outage at a customer location associated with re-tooling efforts.

Metals and Equipment - Increased primarily due to higher pipe and scrap shipments, partially offset by lower steel shipments, which includes the impact of customer plant closures.

Forest Products - Flat as higher lumber shipments, including benefits from a tighter trucking environment, were offset by lower shipments of pulp and paper products, which include the impacts of both customer plant closures and temporary outages.

Fertilizers - Increased due to higher short-haul phosphates shipments.

Intermodal Volume

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

Coal Volume

Export coal increased due to higher shipments of metallurgical and thermal coal, including the benefits of increased production from re-opened mines. Domestic coal decreased due to lower shipments to utility plants, partially offset by higher shipments to steel manufacturing locations and lake terminals.

EXPENSE

Expenses of $2.4 billion increased $138 million, or 6%, in second quarter 2026 when compared to second quarter 2025. Fuel expense increased $177 million compared to prior year while total non-fuel expense decreased $39 million.

Labor and Fringe expense increased $40 million due to the following:

•Incentive compensation increased $56 million driven by higher expected payouts.

•An increase of $32 million was due to inflation.

•All other net costs decreased $48 million primarily due to lower headcount.

Purchased Services and Other expense decreased $66 million due to the following:

•Efficiency savings, net of inflation, of $54 million were driven by cost reductions across operating and support functions.

•A decrease of $14 million was due to the effects of network disruptions and congestion in the prior year, including rerouting impacts.

•Gains on property dispositions of $17 million in second quarter 2026 were primarily due to the sale of the Company's last remaining aircraft in the asset group. Gains were $8 million in the prior year.

•All other net costs increased $11 million, primarily due to intermodal volume increases and advisory expenses related to potential industry consolidation. These increases were partially offset by an insurance recovery related to 2024 property damage on the Blue Ridge subdivision.

Depreciation and Amortization expense decreased $16 million primarily as a result of an equipment depreciation study.

Fuel costs increased $177 million primarily due to a 74% increase in locomotive fuel prices as well as higher non-locomotive fuel prices, partially offset by efficiency savings.

Equipment and Other Rents expense increased $3 million.

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).
