MANAGEMENT COMMENTARY

"During the quarter, we delivered 13% year-over-year revenue growth, including 20% revenue growth in contracting services," said Knife River President and CEO Brian Gray. "That pull-through demand, combined with contributions from acquisitions, helped us generate double-digit volume and gross profit growth across our material product lines. Aggregate pricing also improved by 8% on a product mix-adjusted basis. The fundamentals of our business are strong. During the quarter, headwinds related to energy costs, delayed impact projects, and the type and timing of contracting services impacted Adjusted EBITDA and margins. Last year, we also benefited in the second quarter from $10.3 million in gains on asset sales, compared to just $650,000 this quarter. Despite these factors, we delivered strong operational results year-over-year.

"With the majority of the construction season still ahead of us, we have opportunities to execute on our $1.2 billion contracting services backlog, driving volume and gross profit improvement in all of our product lines," Gray said. "Additionally, we continue to implement our self-help initiatives to improve margins — including price optimization and operational efficiencies.

"The acquisitions we have completed over the last two years also continue to perform as expected, and we have several targets in our pipeline that align with our growth strategy," Gray said. "In addition, we have multiple organic growth projects underway across our footprint, including aggregates reserve expansions designed to strengthen our position, support future earnings growth and create long-term shareholder value."

EBITDA margin		17.0	%		19.1	%				14.2	%		16.3	%

Second quarter revenue decreased 9% year-over-year, primarily due to less available public-agency work in Oregon, as well as delays in Hawaii and Alaska related to project phasing and weather. EBITDA decreased 19% compared to the prior year, reflecting decreased activity and lower-margin contracting services work, partially offset by higher aggregate and ready-mix pricing across the region.

EBITDA margin		13.1	%		17.6	%				7.2	%		6.0	%

Second quarter revenue increased 34% from the prior year, largely driven by an increase in contracting services as well as acquisitions completed in the first quarter. EBITDA was flat, as the revenue growth was primarily offset by the timing of project performance gains and lower-margin contracting services work.

EBITDA margin		16.5	%		17.4	%				6.3	%		6.2	%

Second quarter revenue increased 28% from the prior year, primarily driven by increased volumes across all product lines as well as contributions from the Texcrete acquisition. EBITDA improved 21%, with a majority of the increase being attributed to aggregate sales, as well as higher margins on contracting services work. However, EBITDA margin declined as the prior-year period benefited from $7.9 million of gains on asset sales that did not recur this quarter.

EBITDA margin		19.2	%		17.5	%				12.3	%		8.3	%

Second quarter revenue increased 6% from the prior year, driven by increased volumes due to improved market opportunities in California. EBITDA improved 16%, largely because of the increased sales volumes in California, as well as lower railcar maintenance expenses compared to prior year.

CAPITAL ALLOCATION & LIQUIDITY

The company is committed to disciplined capital allocation, including reinvesting to maintain fixed assets, strengthening operations and growing the business.

The company currently estimates total 2026 capital expenditures for maintenance and improvement to be between 5% and 7% of revenue. For the six months ending June 30, 2026, the company spent $90.1 million, largely on the replacement of construction equipment and plant improvements.

Additionally, for the six months ended June 30, 2026, the company spent $244.5 million on growth initiatives, which was comprised of $184.4 million on acquisitions and $60.1 million on aggregate expansions and greenfield projects. For the remainder of 2026, the company expects to spend $76.4 million on organic growth projects. Capital expenditures for future acquisitions and new growth opportunities would be incremental to the outlined capital program. It is anticipated that capital expenditures for the remainder of 2026 will be funded by various sources, including cash from operations and debt.

On May 15, 2026, the company issued an incremental $400 million Term Loan B facility which was used to finance recent acquisitions and growth initiatives previously discussed, repay borrowings under the Revolving Credit Facility, and for working capital and general corporate purposes.

As of June 30, 2026, Knife River had $40.7 million of unrestricted cash and cash equivalents, $1.6 billion of gross debt and $387.2 million of available capacity under its revolving credit facility, net of outstanding letters of credit. Net leverage, defined as the ratio of net debt to trailing-twelve-month Adjusted EBITDA, was 3.2x at June 30, 2026.

NON-GAAP FINANCIAL MEASURES

EBITDA, EBITDA margin, Adjusted EBITDA, Adjusted EBITDA margin, as well as total segment measures, as applicable, net debt and net leverage are 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 of net 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 and structures, 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 plan investments, 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 not believe 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 who utilize 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 it would 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 results when 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 unrealized gains 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. Net leverage 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 financial measures 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 to compare 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.

The following table provides the reconciliation of net income (loss) to EBITDA and Adjusted EBITDA.

Knife River’s projections for 2026 Adjusted EBITDA is a non-GAAP financial measure that excludes or otherwise has been adjusted for non-GAAP adjustment items from Knife River’s financial statements. When the company provides its forward-looking 2026 Adjusted EBITDA, it does not provide a reconciliation of these non-GAAP financial measures as Knife River is unable to predict with a reasonable degree of certainty the actual impact of the non-GAAP adjustment items. By their very nature, non-GAAP adjustment items are difficult to anticipate with precision because they are generally associated with unexpected and unplanned events that impact our company and its financial results, including, but not limited to, the potentially high variability, complexity and low visibility with respect to the items that would be excluded from the applicable GAAP 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 of these measures without unreasonable efforts.
