Item 2.02. Results of Operations and Financial Condition.

On ~~May~~July 131, 2025, Kirby Corporation (“Kirby” or the "Company") issued a press release announcing results for the ~~first~~second quarter ended ~~March~~June 3130, 2025. A copy of the press release is attached as Exhibit 99.1 to this report.

EBITDA, a non-GAAP financial measure, is used in the press release. Kirby defines EBITDA as net earnings attributable to Kirby before interest expense, taxes on income, and depreciation and amortization. Kirby has historically evaluated its operating performance using numerous measures, one of which is EBITDA. EBITDA is presented because of its wide acceptance as a financial indicator. EBITDA is one of the performance measures used in calculating performance compensation pursuant to the Company’s annual incentive plan. EBITDA is also used by rating agencies in determining Kirby’s credit rating and by analysts publishing research reports on Kirby, as well as by investors and investment bankers generally in valuing companies. A quantitative reconciliation of EBITDA to net earnings attributable to Kirby for the 2025 and 2024 ~~first~~second quarters and first six months is included in the press release. EBITDA is not a calculation based on generally accepted accounting principles and should not be considered as an alternative to, but should only be considered in conjunction with, Kirby’s GAAP financial information.

The press release also includes non-GAAP financial measures which exclude certain one-time items, including earnings before taxes on income (excluding one-time items), net earnings attributable to Kirby (excluding one-time items), and diluted earnings per share (excluding one-time items). A reconciliation of these measures with GAAP is included in the press release. Management believes that the exclusion of certain one-time items from these financial measures enables it and investors to assess and understand operating performance, especially when comparing those results with previous and subsequent periods or forecasting performance for future periods, primarily because management views the excluded items to be outside of Kirby’s normal operating results. The press release additionally includes free cash flow, a non-GAAP financial measure, which Kirby defines as net cash provided by operating activities less capital expenditures. A reconciliation of free cash flow with GAAP is included in the press release. Kirby uses free cash flow to assess and forecast cash flow and to provide additional disclosures on the Company’s liquidity. Free cash flow does not imply the amount of residual cash flow available for discretionary expenditures as it excludes mandatory debt service requirements and other non-discretionary expenditures. These non-GAAP financial measures are not calculations based on generally accepted accounting principles and should not be considered as an alternative to, but should only be considered in conjunction with Kirby’s GAAP financial information.
