FORWARD-LOOKING STATEMENTS AND NON-GAAP FINANCIAL MEASURES 2 This presentation contains statements concerning future events and expectations, including, without limitation, statements re lating to third quarter 2025 outlook and expected key drivers for Boise Cascade and each of its business segments. These statements constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions, or future events or performance, often, but not always, through the use of words or phrases such as "anticipates," "believes," "could," "estimates," "expects," "intends," "outlook," "potential," "plans," "predicts," "preliminary," "projects," "targets," "may," "may result," or similar expressions, are not statements of historical facts and may be forward-looking. Forward-looking statements are not guarantees of future performance, involve estimates, assumptions, risks, and uncertainties, and may differ materially from actual results, performance, or outcomes. Factors that could cause actual results or outcomes to differ materially from those contained in f orward-looking statements include those factors set forth in Boise Cascade's most recent Annual Report on Form 10-K, subsequent reports filed by Boise Cascade with the Securities and Exchange Commission (SEC), and the following important factors: the commodity nature of a portion of our products and their price movements, which are driven largely by general economic conditions, industry capacity and operating rates, industry cycles that affect supply and demand, and net import and export activity; the highly competitive nature of our industry; declines in demand for our products due to competi ng technologies or materials, as well as changes in building code provisions; disruptions to information systems used to process and store customer, employee, and vendor information, as well as the techn ology that manages our operations and other business processes; material disruptions and/or major equipment failure at our manufacturing facilities; declining demand for residual byproducts, particu larly wood chips generated in our manufacturing operations; labor disruptions, shortages of skilled and technical labor, or increased labor costs; the need to successfully formulate and implement succession plans for key members of our management team; product shortages, loss of key suppliers, and our dependence on third-party suppliers and manufacturers; the cost and availabil ity of third-party transportation services used to deliver the goods we manufacture and distribute, as well as our raw materials; cost and availabil ity of raw materials, including wood fiber and glues and resins; our ability to execu te our organic growth and acquisition strategies efficiently and effectively; failures or delays with new or existing technology systems and software platforms; our ability to successfully pursue our long-term growth strategy related to innovation and digital technology; concentration of our sales among a relatively small group of customers, as well as the financial condition and creditworthiness of our customers; impairment of our long-lived assets, goodwill, and/or intangible assets; substantial ongoing capital investment costs, including those associated with organic growth and acquisitions, and the diffic ulty in offsetting fixed costs related to those investments; our indebtedness, including the possibility that we may not generate sufficient cash flows from operations or that future borrowings may not be available in amounts sufficient to fulfi ll our debt obligations and fund other liquidity needs; restrictive covenants contained in our debt agreements; changes in foreign trade policy, including the impos ition of tariffs; compliance with data privacy and security laws and regulations; the impacts of climate change and related legislative and regulatory responses intended to reduce climate change; cost of complia nce with government regulations, in particular, environmental regulations; exposure to product liability, product warranty, casualty, construction defect, and other claims; and fluctuations in the mar ket for our equity. It is not possible to predict or identify all risks and uncertainties that might affect the accuracy of our forward -looking statements and, consequently, our descriptions of such risks and uncertainties should not be considered exhaustive. There is no guarantee that any of the events antic ipated by these forward -looking statements will occur, and if any of the events do occur, there is no guarantee what effect they will have on the company's business, results of operations, cash flows, financial condition and future prospects. Forward-looking statements speak only as of the date they are made, and, except as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether because of new information, future events, or otherwise. This presentation includes references to EBITDA, Adjusted EBITDA and Segment EBITDA, which are non-GAAP financial measures within the meaning of the SEC's Regulation G. Reconciliations of net income to EBITDA and Adjusted EBITDA and segment income to Segment EBITDA are included as an appendix.
