Kirby Corporation Releases Third-Quarter 2026 Financial Results via 8-K

Kirby Corporation (NYSE:KEX), headquartered in Houston, Texas, filed a current report on Form 8-K on October 28, 2026, under Item 2.02 (Results of Operations and Financial Condition). According to the filing, the company issued a press release on that same date announcing results for the third quarter ended September 30, 2026. The press release is attached as Exhibit 99.1.

The filing discloses that the press release includes several non-GAAP financial measures. Kirby defines EBITDA as "net earnings attributable to Kirby before interest expense, taxes on income, and depreciation and amortization." The filing states that EBITDA "is one of the performance measures used in calculating performance compensation pursuant to the Company's annual incentive plan" and is also used by rating agencies, analysts, investors, and investment bankers. The press release also includes non-GAAP measures that exclude certain one-time items, specifically earnings before taxes on income, net earnings attributable to Kirby, and diluted earnings per share, each excluding one-time items. According to the filing, "management views the excluded items to be outside of Kirby's normal operating results."

Additionally, the filing notes the inclusion of free cash flow as a non-GAAP measure, defined as net cash provided by operating activities less capital expenditures. The filing cautions that "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." Quantitative reconciliations for all non-GAAP measures to their GAAP equivalents, covering both the third quarters and first nine months of 2026 and 2025, are stated to be included within the press release.
