NON-GAAP FINANCIAL MEASURES EBITDA, EBITDA margin, Adjusted EBITDA, Adjusted EBITDA margin, as well as total segment measures, as applicable, net debt and net leverageare considered non-GAAP measures of financial performance. These non-GAAP financial measures are not measures of financial performance under GAAP. The items excluded from these non-GAAP financial measures are significant components in understanding and assessing financial performance. Therefore, these non-GAAP financial measures should not be considered substitutes for the applicable GAAP metric. EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin are most directly comparable to the corresponding GAAP measures ofnet income and net income margin. Net debt and net leverage are most directly comparable to the corresponding GAAP measures of total debt. We believe these non-GAAP financial measures, in addition to corresponding GAAP measures, are useful to investors by providing meaningful information about operational efficiency compared to our peers by excluding the impacts of differences in tax jurisdictions andstructures, debt levels and capital investment. We believe Adjusted EBITDA and Adjusted EBITDA margin are useful performance measures because they allow for an effective evaluation of our operating performance by excluding unrealized gains and losses on benefit planinvestments, stock-based compensation, and the impact of selling acquired inventory after markup to fair value as part of acquisition accounting, as they are considered non-cash and not part of our core operations. We believe EBITDA and Adjusted EBITDA assist rating agencies and investors in comparing operating performance across operating periods on a consistent basis by excluding items management does notbelieve are indicative of the company's operating performance, including using EBITDA and Adjusted EBITDA to calculate Knife River’s leverage as a multiple of EBITDA and Adjusted EBITDA. Additionally, EBITDA and Adjusted EBITDA are important financial metrics for debt investors whoutilize debt to EBITDA and debt to Adjusted EBITDA ratios. We believe EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin, including those measures by segment, are useful performance measures because they provide clarity as to the operational results of the company. Management believes net debt and net leverage are useful performance measures because they provide a measure of how long itwould take the company to pay back its debt if net debt and Adjusted EBITDA were constant. Net leverage also allows management to assess our borrowing capacity and optimal leverage ratio. Our management uses these non-GAAP financial measures in conjunction with GAAP resultswhen evaluating our operating results internally and calculating employee incentive compensation, and leverage as a multiple of Adjusted EBITDA to determine the appropriate method of funding our operations. EBITDA is calculated by adding back income taxes, interest expense (net of interest income) and depreciation, depletion and amortization expense to net income. EBITDA margin is calculated by dividing EBITDA by revenues. Adjusted EBITDA is calculated by adding back unrealizedgains and losses on benefit plan investments, stock-based compensation and the impact of selling acquired inventory after markup to fair value as part of acquisition accounting to EBITDA. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenues. Net debt is calculated by adding unamortized debt issuance costs to the total debt balance presented on the balance sheet, less any unrestricted cash. Netleverage is calculated by dividing net debt by trailing-twelve-month Adjusted EBITDA. These non-GAAP financial measures are calculated the same for both the segment and consolidated metrics and should not be considered as alternatives to, or more meaningful than, GAAP financialmeasures such as net income, net income margin and total debt and are intended to be helpful supplemental financial measures for investors’ understanding of our operating performance. Our non-GAAP financial measures are not standardized; therefore, it may not be possible tocompare these financial measures with other companies’ EBITDA, EBITDA margin, Adjusted EBITDA, Adjusted EBITDA margin, net debt and net leverage measures having the same or similar names. The following information reconciles segment and consolidated net income (loss) to EBITDA and Adjusted EBITDA and provides the calculation of EBITDA margin, Adjusted EBITDA margin, net debt and net leverage. Interest expense, net, is net of interest income that is included in other income (expense) on the Consolidated Statements of Operations. 10

When the company provides its forward-looking 2026 Adjusted EBITDA, it does notprovide a reconciliation of these non-GAAP financial measures as Knife River is unable to predict with a reasonable degree of certainty theactual impact of the non-GAAP adjustment items. By their very nature, non-GAAP adjustment items are difficult to anticipate with precisionbecause they are generally associated with unexpected and unplanned events that impact our company and its financial results, including, butnot limited to, the potentially high variability, complexity and low visibility with respect to the items that would be excluded from the applicableGAAP measure in the relevant future period, such as unusual gains and losses, the impact and timing of potential acquisitions and divestitures,certain financing costs and other structural changes or their probable significance. Therefore, Knife River is unable to provide a reconciliation ofthese measures without unreasonable efforts.
