Exhibit 99.1

CSX Corp. Announces First Quarter 2024 Results

JACKSONVILLE, Fla. – April 17, 2024 – CSX Corp. (NASDAQ: CSX) today announced first quarter 2024 operating income of $1.35 billion compared to $1.46 billion in the prior year period. Net earnings were $893 million, or $0.46 per diluted share, compared to $987 million, or $0.48 per diluted share, in the same period last year. Total volume of 1.53 million units for the quarter was 3% higher compared to first quarter 2023, with intermodal volume up 7%, coal volume up 2%, and merchandise volume flat.

“Working together, the ONE CSX team delivered a good start to the year that was in-line with our expectations,” said Joe Hinrichs, president and chief executive officer. “We were pleased to see our consistent customer service performance lead to volume growth, and we remain focused on improving the reliability and fluidity of our network. Looking ahead, with favorable trends across many of the markets we serve, we are eager to build on our momentum over the rest of the year and beyond.”

First Quarter Financial Highlights

•Revenue totaled $3.68 billion for the quarter, declining 1% year-over-year as lower fuel surcharge, a decline in other revenue, weaker trucking revenue, and reduced export coal prices offset gains in merchandise pricing and higher intermodal and coal volumes. First quarter revenue was flat sequentially.

•Operating income of $1.35 billion decreased 8% compared to the same period in 2023 but increased 3% from Q4 2023. CSX’s operating margin was 36.8% for the quarter, declining 270 basis points year-over-year but increasing 90 basis points sequentially.

•Diluted EPS of $0.46 decreased 4% from $0.48 in the prior year but increased 2% compared to the previous quarter.

VOLUME AND REVENUE

Total revenue decreased 1% in the first quarter 2024 when compared to first quarter 2023 primarily due to lower fuel recovery, decreases in other revenue, lower trucking revenue, and pricing declines in export coal due to the impact of lower benchmark rates. These decreases were partially offset by pricing gains in merchandise as well as higher intermodal and coal volumes.

Fuel Surcharge

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

Fuel Surcharge Revenue	$	277	$	361
Fuel Lag Favorable (Unfavorable)	$	6	$	41

Merchandise Volume

Chemicals - Increased due to higher shipments of plastics, crude oil, and natural gas liquids, partially offset by lower shipments of frac sand.

Agricultural and Food Products - Decreased primarily due to lower domestic and export shipments of grain, partially offset by higher shipments of vegetable oils.

Automotive - Increased due to higher North American vehicle production as well as new business wins.

Minerals - Decreased due to lower shipments of aggregates, partially offset by increased shipments of cement.

Forest Products - Increased shipments of pulpboard were offset by lower shipments of woodpulp and paper.

Metals and Equipment - Decreased due to lower steel and scrap shipments. Equipment was relatively flat to prior year as increased volume for repositioning empty railcars was offset by reduced loaded shipments.

Fertilizers - Decreased due to declines in short-haul shipments, which were partially offset by increases in long-haul phosphate and potash shipments.

Intermodal Volume

Intermodal volume increased primarily due to international shipments driven by higher imports through east coast ports and inventory replenishments. Domestic shipments also increased due to growth with key customers despite a soft trucking environment.

Coal Volume

Export coal increased due to higher shipments of thermal and metallurgical coal. Domestic coal decreased primarily due to lower shipments of coal to utility plants, as well as lower shipments to river and lake terminals.

Export	11.6	9.3	25
Total Coal	21.2	20.8	2	%

Trucking Revenue

Trucking revenue decreased $18 million versus the prior year due to lower fuel and capacity surcharges.

Other Revenue

Other revenue was $35 million lower, primarily resulting from lower carload demurrage as well as lower intermodal storage and equipment usage.

CSX Corporation

EXPENSE

Expenses of $2.3 billion increased $85 million, or 4%, in first quarter 2024 when compared to first quarter 2023.

Labor and Fringe expense increased $75 million due to the following:

•An increase of $26 million was due to cost increases attributed to higher headcount and union employee sick benefits.

•An increase of $23 million was driven by inflation.

•Other costs, including incentive compensation and other employee-related items, increased $26 million.

Purchased Services and Other expense increased $23 million due to the following:

•Prior year amounts included a $46 million insurance recovery.

•An increase of $13 million was due to inflation and higher volume.

•Other costs decreased $36 million, about half of which resulted from efficiency savings across the organization.

Depreciation and Amortization expense increased $17 million as a result of a larger asset base.

Fuel costs decreased $39 million primarily resulting from a 10% decrease in locomotive fuel prices.

Equipment and Other Rents expense increased $2 million driven by higher volume.

Gains on Property Dispositions decreased to $1 million from $8 million in the prior year.

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.

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.

Economic Profit

Management believes Economic Profit (also referred to as CSX Cash Earnings or CCE) provides an additional perspective to investors about financial returns generated by the business by representing a measure showing profit generated over and above the cost of capital used by the business to generate that profit. Economic Profit is designed to incentivize strategic investments that earn more than management’s desired minimum required return and is broadly utilized by management to make investment decisions. Therefore, disclosing Economic Profit on how management performs in this regard provides additional useful information to investors regarding the Company’s performance compared to its goals.

Economic Profit should be considered in addition to, rather than a substitute for, operating income, which is the most directly comparable GAAP measure. Economic Profit is defined by the Company as Gross Cash Earnings (“GCE”) minus the Capital Charge on Gross Operating Assets (“GOA”). Increases in Economic Profit indicate that the Company is effectively allocating capital and rewarding shareholders by generating returns in excess of the incremental cost of capital associated with reinvestment in the business.

GCE is calculated as operating income plus depreciation, amortization and operating lease expense, less unusual items and taxes. The Capital Charge uses a minimum required return multiplied by the GOA. CSX's GOAs include gross properties and other non-cash assets, net of non-interest bearing liabilities. The Company used a 15% tax rate and an 8% required return, for both periods presented, which is consistent with rates used for investment decisions and performance evaluation within those same periods. The tax rate is the approximate equivalent of the Company’s actual income tax expense as a percentage of pre-tax GCE. The required return rate represents management’s desired minimum return on any investment. CSX annually re-evaluates these rates to ensure they accurately represent taxes and a required return in light of internal and external factors and would adjust the rate if the annual review resulted in a preset deviation from the current rates. This focuses the Economic Profit measure on value generated by management instead of external factors, such as legislative tax policy or interest rate volatility.

(a) Unusual items are defined by management as unique events with greater than $100 million full year operating income impact, consistent with the terms of the Company's long-term incentive plan agreements. There were no unusual items for either period presented.

(b) The tax percentage rate was 15% for both periods presented. This rate is applied to the sum of operating income, depreciation, amortization and operating lease expense, and unusual items.

(c) Gross operating assets reflects an average of the year-to-date quarters reported for each year presented. Averages are not applicable for the first quarter of each year.

(d) The capital charge of 8% for both years is calculated as the minimum return multiplied by gross operating assets. This is an annualized rate equivalent to 2% per quarter.

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 decrease in FCF before dividends from the prior year of $256 million is primarily due to less cash from operating activities and higher property additions. Cash from operating activities in the three months of 2024 includes the impact of $387 million of federal tax payments related to the 2023 tax year that were previously postponed under an Internal Revenue Service tax relief announcement for those impacted by Hurricane Idalia. Cash from operating activities in the prior year period includes the payment of $232 million for retroactive wages and bonuses, and associated taxes, related to finalized labor agreements.

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