LETTER FROM OUR BOARD CHAIR AND LEAD INDEPENDENT DIRECTOR

Fellow Shareholders:

It has been our pleasure to serve on the Boise Cascade Company Board these past years. As we retire from the Board, in accordance with our Director retirement policy as of our 2026 Annual Meeting of Shareholders, we are confident that the Company’s Board and management will execute on the Company’s strategic plan. We look forward to the continued leadership of Nate Jorgensen and Kristopher Matula as described later in this letter, assuming their reelection to the Board.

You are cordially invited to join us for our 2026 Annual Meeting of Shareholders, which will be held on Thursday, April 30, 2026, at 9:30 a.m. Mountain Daylight Time via live webcast. You will be able to attend the Annual Meeting online, where you can vote your shares electronically and submit questions by visiting www.virtualshareholdermeeting.com/BCC2026 . The Notice of Annual Meeting of Shareholders and the Proxy Statement that follow describe the business to be conducted at the meeting.

As we look forward to our 2026 Annual Meeting of Shareholders, it is worth reflecting on the year just completed.

	●			●
	THOMAS CARLILE BOARD CHAIR (until April 30, 2026)			DAVID HANNAH LEAD INDEPENDENT DIRECTOR (until April 30, 2026)
	●			●
	NATE JORGENSEN BOARD CHAIR (as of April 30, 2026)			KRISTOPHER MATULA LEAD INDEPENDENT DIRECTOR (as of April 30, 2026)

Capital Allocation Strategy in 2025

In 2025, we invested approximately $275 million in capital spending projects and acquisitions, all as part of our long-term strategy. In our BMD segment, we opened a greenfield distribution facility in Hondo, Texas and acquired a new distribution facility in Chicopee, Massachusetts. In our Wood Products segment, we completed a multi-year project to significantly modernize our Oakdale, Louisiana mill, and have nearly completed the addition of I-joist production capabilities at our Thorsby, Alabama (EWP) mill.

In 2026, we remain committed to executing our reinvestment and growth strategies by continued capital expenditures in our distribution capabilities, including investments in our previously announced greenfield distribution facility in South Carolina, in

our Hatfield, Massachusetts door and millwork facility, and in our recently acquired Boise, Idaho door and millwork facility. In our manufacturing facilities, we are continuing the integration of capital projects at our Oakdale, Louisiana and Thorsby, Alabama mills.

In addition, in 2025, we returned $216.0 million of cash to our shareholders by increasing our quarterly dividend to $0.22 per share and repurchasing approximately 2.1 million shares of our common stock. We believe that the continued execution of our long-term growth plan and thoughtful stewardship of your capital will help ensure that you receive the benefits of our strategy and investments in the years to come.

TABLE OF CONTENTS

LETTER FROM OUR BOARD CHAIR AND LEAD INDEPENDENT DIRECTOR

Board Oversight of Corporate Strategy

The Board’s role is critical in overseeing our corporate strategy and operations, and we continue to work closely with the management team on matters regarding the business and its performance. Throughout the past year, the Board meeting agendas regularly included significant business and organizational initiatives, capital allocation strategies, and business development opportunities to increase both our earnings and earnings stability by expanding our distribution capabilities, including door and millwork operations and

growing our market position in EWP. These discussions allowed the Board to review how the management team leveraged our integrated business model, drove operational excellence by using data-driven process improvement programs, including asset monitoring applications for predictive maintenance, and highly efficient logistics systems, accelerated the pace of innovation and digital technology, and continued to foster a connected workplace culture.

Leadership Changes and Ongoing Board and Committee Refreshment

We continue to execute on our succession plan and have experienced several leadership changes, including in early 2025, when we elected a chief operating officer to oversee our BMD and Wood Products segments, promoted an officer to the executive vice president of our BMD segment, and promoted an officer to a senior vice president in our BMD segment. In early 2026, we elected two new officers, one in each of our BMD and Wood Products segments.

Additionally, in late 2025, we announced the election of a new chief executive officer, Jeff Strom, effective March 3, 2026, with the retirement of our former chief executive officer, Mr. Jorgensen, on March 2, 2026. Mr. Jorgensen will remain on the Board as a Director after his retirement, and assuming his reelection to the Board, the Board intends to elect him as Board chair due to his strong leadership skills and industry experience, and the growth of the Company during his tenure as the chief executive officer of the Company. Assuming he is elected to the Board, Mr. Strom will become a Director.

Assuming his reelection, Mr. Matula will replace David Hannah as our current Lead Independent Director. Mr. Matula’s experience as the current chair of the compensation committee and member of both the compensation and corporate governance and nominating committees since his first election to the Board, along with prior experience in c-suite positions, provides the Board with experienced leadership and strong corporate governance and compliance skills. Additionally, assuming their reelection, we will refresh the chairs of the audit committee to Amy Humphreys and the compensation committee to Sue Taylor.

Whether or not you plan to attend the 2026 Annual Meeting of Shareholders, your vote is important, and we encourage you to vote your shares promptly. You may vote your shares online or by using a toll-free telephone number. If you received a paper copy of the proxy card by mail, you may sign, date, and mail the proxy card in the envelope provided. Instructions regarding the three methods of voting are contained on the Notice of Internet Availability of Proxy Materials and the proxy card.

Sincerely,

Thomas Carlile Board Chair David Hannah Lead Independent Director

		Note about Forward-Looking Statements
		This proxy statement contains statements concerning future events and expectations, including, without limitation, statements relating to 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 forward-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 competing 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 technology that manages our operations and other business processes; material disruptions and/or major equipment failure at our manufacturing facilities; declining demand for residual byproducts, particularly wood chips generated in our manufacturing operations; labor disruptions, shortages of skilled and technical labor, or increased labor costs; product shortages, loss of key suppliers, and our dependence on third-party suppliers and manufacturers; the cost and availability of third-party transportation services used to deliver the goods we distribute and manufacture, as well as our raw materials; cost and availability of raw materials, particularly wood fiber; the need to successfully formulate and implement succession plans for key members of our management team; our ability to execute 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 difficulty 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 fulfill our debt obligations and fund other liquidity needs; restrictive covenants contained in our debt agreements; changes in or failure to comply with laws and regulations; changes in foreign trade policy, including the imposition 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 compliance with government regulations, in particular, environmental regulations; exposure to product liability, product warranty, casualty, construction defect, and other claims; and fluctuations in the market 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 anticipated 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 proxy statement includes references to EBITDA and Adjusted 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 are included in the Company’s Form 10-K filed on February 24, 2026.
		Any and all website addresses included in this proxy statement are included as textual references only, and none of the information contained in such websites (or accessed through them) is incorporated into this proxy statement or shall be regarded as part of this proxy statement.

Together, we strive to create an injury-free environment by identifying risks, eliminating hazards, and requiring safe behaviors.			We cultivate a climate of mutual respect, camaraderie, and teamwork.

Executing Our Strategy

Our strategy focuses on the “critical few” deliverables over the next two to five years to provide clarity and focus on our goals and adopt a common language around our collective opportunities ahead. Specifically, we intend to continue to:

1			2			3			4
Increase our earnings and earnings stability by expanding our distribution capabilities and growing our market position in EWP.			Leverage our integrated business model and superior access to the market for our Wood Products segment through our BMD segment.			Drive operational excellence by using data-driven process improvement programs and highly efficient logistics systems.			Accelerate the pace of innovation and digital technology and continue to foster a connected workplace culture.

2025 Business Highlights

In 2025, despite a weaker demand environment than 2024, we successfully executed our strategy and were able to:

Deliver solid earnings in both our BMD and Wood Products segments

Continue growth and expansion of our BMD distribution and door and millwork operations

Continue innovation through use of data-driven technologies to increase the quality of decision making at all levels in our BMD segment and to

decrease equipment downtime and expand the use of predictive analytics in our Wood Products segment

Continue capital investments in support of our EWP growth strategy

Continue innovation through active product development opportunities, including development of new products for commercial construction applications in our Wood Products segment

Ready to Respond to Market Changes and Well-Positioned for Continued Growth

In 2026, we expect new single-family residential construction to be flat or modestly down from 2025, while multi-family construction is expected to level off in 2026 after double-digit growth in 2025, and repair-and-remodel is expected to be flat in 2026. As market conditions dictate, we will adjust our business where needed and continue to seek ways to control expenses and discretionary costs without sacrificing the high service levels expected by our supplier and customer partners. In addition, given the favorable long-term outlook for the demand fundamentals that drive our business, we will continue to make investments to grow our Company and enhance the workplace experience to retain and attract talented employees. In 2026, we plan to continue executing our strategy and creating attractive returns on capital by:

●

Pursuing organic growth opportunities and in-fill opportunities in strategic locations across the country for our distribution business

●

Continuing our growth in door and millwork operations

●

Enhancing and upgrading our EWP manufacturing capabilities

●

Continuing to improve our competitiveness through operational excellence

●

Using our Boise Improvement Cycle (BIC) process and business optimization group to continue to (i) increase productivity, (ii) increase equipment efficiency, and (iii) lower our costs of manufacturing

●

Evaluating and executing upon inorganic growth opportunities that increase operational capabilities and market share, and/or grow our total addressable market

Executive Compensation Highlights

We provide highlights of our executive compensation program below. It is important to review the Compensation Discussion & Analysis (CD&A) and compensation tables in this proxy statement for a complete understanding of our compensation program and philosophy (page 36 ).

We generally target compensation at the 50th percentile of comparable market compensation data, with actual compensation amounts reflecting each person’s role, performance, contributions to the Company’s success, level of experience, and other distinguishing qualifications.

We provide at-risk performance-based pay opportunities in the form of short-term and long-term incentives.

Our chief executive officer’s (CEO) total compensation is 51% at-risk, while our other named executive officers’ (NEO) total compensation is an average 47% at-risk.

Short-term and long-term incentives comprise a significant portion of each NEO’s total compensation opportunity and are designed to motivate and reward our NEOs for growing the Company and maximizing long-term shareholder value.

Long-term performance is the most important measure of our success because we manage our operations and business affairs for the long-term benefit of our shareholders.

For 2025, our NEOs received long-term equity incentive compensation opportunities in a combination of Performance Stock Units (PSUs) and Restricted Stock Units (RSUs).

We maintain robust clawback policies that cover time-based and performance-based equity and cash awards:

●

Under our equity incentive plans, the Company

has the ability to clawback all equity awards, both time-based and performance-based, upon various events including upon misconduct related to a restatement.

●

Additionally, under our Misconduct Clawback Policy, both time-based and performance- based incentive compensation may be subject to recoupment if (i) as a result of a financial restatement, the award would have been lower had the financial results been properly calculated when originally reported, (ii) an award was predicated on achieving financial results that were subsequently determined to be due to a fraudulent act by the officer, or (iii) an officer engaged in misconduct, including misconduct that results in reputational or financial harm to the Company, even if such misconduct does not result in a financial restatement.

●

Finally, under our Executive Compensation Clawback Policy adopted in 2023 pursuant to Rule 10D-1 of the Exchange Act, we are required to recoup performance-based incentive compensation received on or after October 2, 2023 that was calculated based on financial results that were subsequently restated and the award received would have been lower if based on the restated results.

Our annual incentive compensation opportunities are tied to the achievement of corporate goals and, in some cases, business segment financial goals.

Our Insider Trading Policy prohibits all of our Directors, officers, employees, and consultants from participating in any hedging, pledging, or monetizing transaction to lock in the value of any of our securities they hold, including the purchase of any financial instrument designed to offset the risk of future declines in the market value of any of our securities.

Say on Pay

Over the past five years, our shareholders have shown strong support for our executive compensation program with average annual vote results of over 96% from 2021 to 2025. Our compensation committee continues to examine our executive compensation program to ensure alignment between our executives and the long-term interests of our shareholders.

We ask that our shareholders approve, on an advisory basis, the frequency of the advisory vote regarding executive compensation as further described in Proposal No. 2 (page 33 ). We also ask that our shareholders approve, on an advisory basis, the compensation of our NEOs as further described in Proposal No. 3 (page 34 ).

2025 Key Compensation Actions and Decisions

2025 RSUs and PSUs under our long-term equity-based award agreements (LTIP) under our 2016 Boise Cascade Omnibus Incentive Plan (2016 Omnibus Incentive Plan) were granted in March 2025. The PSUs granted are subject to a three-year performance period. The number of shares actually awarded will range from 0% to 200% of the target amount. Achievement will be measured against the target payout based on return on invested capital (ROIC) (1) measures (2) for each

of the years 2025, 2026, and 2027. The average achievement for the three years included in the performance period shall determine the performance against target ROIC, which will be determined in February 2028, and the earned shares will be distributed in March 2028, three years from the grant date. The Company believes the performance period for these PSUs aligns management with long-term shareholder value.

(1)

ROIC is defined as Net Operating Profit After Taxes (NOPAT) divided by average invested capital (based on a rolling thirteen-month average). We define NOPAT as net income plus after-tax finance expense. Invested capital is defined as total assets plus capitalized lease expense, less cash, cash equivalents, and current liabilities, excluding short-term debt.

CORPORATE GOVERNANCE AND BOARD MATTERS

Our Board recommends shareholders vote FOR all of our Directors.

All Directors are nominated for election at our 2026 Annual Meeting for a one-year term.

Shares will be voted according to shareholder instructions. If no voting instructions are provided, a broker may not vote on the matter. For 2026, all Directors are running unopposed. Therefore, to be elected to our Board in 2026, each Director must receive an affirmative vote of the majority of the votes of the shares present in person or by proxy at the meeting and entitled to vote.

The Directors have confirmed their availability for election. If any Director becomes unavailable to

serve as a Director for any reason prior to the Annual Meeting, our Board may substitute another person as a Director. In that case, if a shareholder has voted for the original Director, those shares will be voted FOR the substitute Director.

Additional information regarding the Directors follows, particularly concerning their business experience and qualifications, as well as attributes and skills that led our Board to conclude that each nominee should serve as a Director.

Director Skills Matrix

Provided below in a Board Skills Matrix is a summary of each Director’s skills and experience. The skills categories included in the matrix are tied to the Company’s strategic goals, and the intent of the matrix is that the Directors collectively possess qualities that facilitate effective oversight of the Company’s strategic plans. While the matrix is useful for determining the collective skills of the Board as a whole, it is not a comparative measure of the value of Directors; a Director with more focused experience could nonetheless contribute broadly and effectively.

The chart below identifies the principal skills that the corporate governance and nominating committee considered for each Director when evaluating the Director’s experience and qualifications to serve as a Director. Each mark indicates a strength or personal qualification that was self-selected by each Director. Additional information about each Director’s background and business experience is provided below in the biographical information.

Corporate Governance

Code of Ethics for Our Board

The Company’s Code of Ethics (Code of Ethics) applies to our Directors, officers, and employees. We have a toll-free reporting service available that permits employees to confidentially report violations of our Code of Ethics or other issues of significant concern via phone, text, or website.

If we amend or grant a waiver of one or more of the provisions of our Code of Ethics, we intend to satisfy the requirements under Item 5.05 of

Form 8-K regarding the disclosure of amendments to or waivers from provisions of our Code of Ethics by posting the required information on our website.

Corporate Governance Guidelines

Our Board has adopted Corporate Governance Guidelines (Guidelines) to assist the Board in exercising its responsibilities. The Guidelines reflect our Board’s commitment to monitor the effectiveness of policy and decision-making, both at the Board and management levels. Our Board believes the Guidelines enhance our ability to achieve our goals and long-term success and assist us in increasing shareholder value. The Guidelines are in addition to and are not intended to change or interpret any federal or state law or regulation, including the Delaware General Corporation Law, our Certificate of Incorporation, bylaws, or the rules

of the New York Stock Exchange (NYSE). Our Board may modify the Guidelines from time to time at the recommendation of the corporate governance and nominating committee and as deemed appropriate by our Board.

You may view a copy of our Guidelines by visiting our website at www.bc.com/investors , selecting the Corporate Governance tab, and then clicking on the Corporate Governance Guidelines link under Governance Documents .

Director Independence

Our Directors believe Board independence is important and is key for the Board to function properly, allowing it to provide appropriate oversight and maintain managerial accountability.

We list our common stock on the NYSE. The NYSE rules require that a majority of our Directors be independent from management and that all members of our Board committees be independent. For a Director to be independent under the NYSE’s rules, our Board must determine affirmatively that he or she has no material relationship with the Company. Additionally, he or she cannot violate any of the bright line independence tests set forth in the NYSE listing rules that would prevent our Board from determining that he or she is independent. These rules contain heightened independence tests for members of our audit and compensation committees. Our Board will broadly

consider all relevant facts and circumstances to determine the independence of any Director in accordance with the NYSE listing rules.

Our Board has determined that all Director nominees except Messrs. Jorgensen and Strom are independent Directors as defined under the NYSE’s listing rules. These Directors constitute a majority of our Directors and represent all of our committee members.

Additionally, our Board has determined that (i) each member of the audit committee meets the heightened independence standards for audit committee service under the NYSE listing rules and Rule 10A-3 under the Exchange Act; and (ii) each member of the compensation committee meets the heightened independence standards for compensation committee service under the NYSE listing rules and Rule 10C-1 under the Exchange Act. Further, because Mr. Jorgensen is a past CEO of the Company, our Board intends to elect Mr. Matula as its lead independent director assuming his reelection to the Board.

Our Board and its committees can retain, at their sole discretion and at our expense, independent financial, legal, compensation, or other advisors to represent the independent interests of our Board or its committees.

Related-Person Transactions

Family Relationships

No family relationships exist between any of our Directors and executive officers.

Affiliated-Company Transactions

There were no affiliated-company or related person transactions in 2025.

18 | Boise Cascade Company 2026 Proxy Statement

TABLE OF CONTENTS

Proxy Statement Summary Corporate Governance and Board Matters Executive Compensation Audit-Related Matters Stock Ownership Information about Our Annual Meeting

Policies and Procedures for Related- Person Transactions

Our written policy regarding transactions with related persons requires that a “related person” (as defined in paragraph (a) of Item 404 of Regulation S-K) must promptly disclose to our general counsel any “related-person transaction” (defined as any transaction that is reportable by us under Item 404(a) of Regulation S-K in which we are or will be a participant and the amount involved exceeds $120,000, and in which any related person has or will have a direct or indirect material interest) and all material facts with respect thereto.

The general counsel will promptly communicate such information to our audit committee or another independent body of our Board. No related-person transaction will be entered into without the approval or ratification of our audit committee or another independent body of our Board. It is our policy that Directors recuse themselves from any discussion or decision affecting their personal, business, or professional interests. Our policy does not specify the standards to be applied by our audit committee or another independent body of our Board in determining whether to approve or ratify a related-person transaction.

Role of Compensation Consultant

The compensation committee continued to retain Frederic W. Cook & Co., Inc. (FW Cook) as its independent compensation consultant to assist the committee in discharging its responsibilities. In connection with retaining FW Cook, the compensation committee considered that FW Cook

does not provide any other services to the Company or management and determined that there was no conflict of interest according to the factors the compensation committee determined to be relevant, including the independence factors enumerated by the NYSE.

Role of Board in Our Risk Management Processes

Our Board oversees the risk management activities designed and implemented by our management. The Board executes its oversight responsibility for risk management both directly and through its committees. Through our annual enterprise risk management review, the Board also considers specific risk topics, including risks associated with our strategic plan, business operations, cybersecurity, AI, sustainability and environmental matters, HCM strategies (including employee engagement, growth, fostering a sense of community, and expanding our talent pipeline), recoupment of officer compensation based on our clawback policies, and capital structure. In addition, the Board receives regular detailed reports from our senior management and other personnel, including assessments and potential mitigation of the risks and exposures involved with their respective areas of responsibility.

Our Board delegates to the audit committee oversight of our risk management process. Our other committees also consider, and address risks related to their respective committee responsibilities. All committees report to the Board as appropriate, including when a matter rises to a material or enterprise-level risk.

Our internal audit department annually develops a risk-based audit plan that is reviewed with the audit committee, along with the results of internal audit

reviews and activities. The internal audit department also maintains a high-level assessment of risks and controls for key operations, functions, processes, applications, and systems within the Company. The audit committee meets quarterly with our chief financial officer, senior vice president of finance and investor relations, our directors of internal audit and financial reporting, and our senior director of regulatory affairs (compliance and privacy officer).

Information Security

The Board and the audit committee engage with management on a quarterly basis regarding our IT environment, including data security, data privacy, and cybersecurity risks. To help mitigate the risk of potential financial and operational impacts, the Company is guided by industry-recognized frameworks, including the National Institute of Standards and Technology’s (NIST) Cybersecurity Framework and the Control Objectives for Information and Related Technology (COBIT) framework. The Company also maintains cybersecurity insurance coverage with 24/7 incident response. The Company’s IT security, data privacy and internal audit teams include professionals who hold recognized third-party certifications.

Each year, both KPMG and our internal audit team perform audits of the Company’s IT general controls

to evaluate the internal control environment and the reliability of information used in financial reporting. Additional annual risk and security activities include Enterprise Risk Management (ERM) initiatives, employee security and awareness training, data breach tabletop exercises, external reviews of Company manufacturing security posture, and penetration testing by qualified third party vendors to assess our IT perimeter security and intrusion detection capabilities. The Company’s IT environment demonstrates a strong commitment

to policy and compliance management, robust infrastructure and security platforms, advanced threat detection and response, data privacy compliance and governance, access control and authentication, email and data security, and data encryption.

For more information concerning our information security, please refer to Item 1C. Cybersecurity of the Company’s Form 10-K filed on February 24, 2026.

Risk Analysis of Employee Compensation Policies and Practices

The compensation committee, with recommendations from management, reviewed our compensation philosophy for our employees and determined that it does not induce our employees to take unacceptable levels of business risk for the purpose of increasing their incentive plan awards at the expense of shareholder interests. Some of the considerations in making this determination were:

None of our businesses present a high-risk profile because our businesses compete in markets with a high degree of transparency on pricing and costs, as well as clearly defined revenue recognition accounting principles

Our incentive pay structure rewards performance in both the short-term and long-term (i.e., short-term incentives are not paid at the expense of long-term shareholder value)

Our incentive pay program has minimum and maximum targets designed to take into account short-term and long-term affordability measures, with payments capped at the maximum target

The compensation committee reserves the right to reduce or eliminate any awards, at its discretion, with respect to our incentive pay programs

Under the omnibus stock plans (the 2016 Omnibus Incentive Plan and the 2025 Omnibus Incentive Plan), the Company has the ability to clawback all equity awards, both time-based and performance-based, upon various events including upon misconduct related to a financial restatement. Additionally, for LTIP and cash- based short-term incentive plan (STIP) awards received by an officer, our Misconduct Clawback Policy allows us to recoup any or all of the LTIP or STIP awards (both time-based and performance-based) received by an officer (i) if, as a result of a financial restatement, the award would have been lower had the financial results been properly calculated when originally

reported, (ii) if an award was predicated on achieving financial results that were subsequently determined to be due to a fraudulent act by the officer or (iii) if an officer engaged in misconduct, including misconduct that results in reputational or financial harm to the Company, even if such misconduct does not result in a financial restatement

Our Executive Compensation Clawback Policy for our PSU and our STIP awards (performance-based only) pursuant to Rule 10D-1 of the Exchange Act requires recoupment of any or all awards received by an NEO where the amount of the award was calculated based upon the financial results that were subsequently affected by a restatement of the Company’s financial statements and the award received would have been lower had the financial results been properly calculated when initially reported

Our executive compensation program does not encourage our management to take unreasonable risks relating to the business

Pursuant to the Company’s Insider Trading Policy, we prohibit all of our Directors, officers, employees, and consultants from participating in any hedging, pledging, or monetizing transactions to lock in the value of any of our securities that they hold, including the purchase of any financial instrument designed to offset the risk of future declines in the market value of any of our securities

The Company has an Insider Trading Policy governing the purchase, sale and other dispositions of Company securities by Directors, officers, employees, consultants, and the Company itself that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards. A copy of the policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025

Through this process, members of the corporate governance and nominating committee consult with our Board chair and lead independent director and accept nominee recommendations from other Directors and/or shareholders in accordance with the terms of our Certificate of Incorporation and bylaws. The invitation to join our Board is extended by our Board through our Board chair and lead independent director.

Suitability of Candidates

When evaluating the suitability of candidates, in addition to our ongoing and emerging business needs, our Board and corporate governance and nominating committee consider many factors, including a candidate’s:

●

Experience as a senior officer in a public company, substantial private company experience, or other comparable experience

●

Experience as a director of a public company

●

Breadth of knowledge about issues affecting the Company and/or its industry

●

Expertise in finance, logistics, manufacturing, distribution, law, human resources, cybersecurity, technology and innovation, marketing or other areas that our Board determines are important areas of needed expertise

●

Personal attributes that include integrity and sound ethical character, absence of legal or regulatory impediments, absence of conflicts of interest, demonstrated track record of achievement, ability to act in an oversight capacity, appreciation for the issues confronting a public company, adequate time to devote to our Board and its committees, and willingness to assume Board fiduciary responsibilities on behalf of all shareholders

The corporate governance and nominating committee is committed to a highly functioning Board where the composition is reflective of the long-term strategy of the business, and makes decisions primarily on the basis of skills, qualifications, and experience. Input from the Board and management, feedback from shareholders, and Board evaluation processes also help determine desired backgrounds and skills.

Other Considerations in Nomination Process

As of the 2026 Annual Meeting, assuming their election or reelection, as applicable, of all Director nominees to the Board, our Board will consist of seven men and three women with a rich mixture of educational, professional, and experiential differences representing a wide range of perspectives to further enhance the effectiveness of its oversight role. As opportunities to appoint and nominate new Directors become available as the Board builds the slate of Director nominees, in addition to the factors set forth above, our Board recognizes and values candidates and Directors who bring different perspectives. Openness to all perspectives enriches the current and long-term strategic needs of the Company.

Information regarding the skills of our Directors can be found in the Director Skills Matrix on page 11 .

Shareholder Nominations for Directors

In accordance with our bylaws, the corporate governance and nominating committee will consider shareholder nominations for Directors (please refer to the Shareholder Proposals for Inclusion in Next Year’s Proxy Statement section in this proxy statement for related instructions, page 67 ). We did not receive any shareholder nominations or recommendations for a Director in connection with the 2026 Annual Meeting. Other than the procedures set forth in our bylaws, the corporate governance and nominating committee has not adopted formal policies regarding shareholder nominations for Directors because the committee does not believe such policy is necessary for the consideration of shareholder nominations.

In December of each year, under the direction of the corporate governance and nominating committee, our Directors complete written surveys to evaluate and assess the overall effectiveness of our Board, its committees, and each Director. The purpose of the Board, committee(s), and individual Director surveys is to continually improve Board performance. Our lead independent director and our Board chair review the Directors’ responses and provide the individual Directors, the corporate governance and nominating committee, and the Board with an assessment of the performance of the

Board and its committees. The Directors then discuss the results and proposed actions for improvement or change in an executive session chaired by our lead independent director. The lead independent director and Board chair also have one‑on-one discussions as necessary with each Director about the feedback received. Through this process, the Board and management work together to refine the meeting materials and topics covered with the Board to educate new members and highlight certain strategic projects.

Director Time Commitment Policy

The Board believes that wider perspectives and best practices learned by Directors serving in other public directorships must be balanced against the time commitment that service on boards entails. Therefore, our Guidelines include a policy whereby our non-employee Directors are limited to no more than three public boards (in addition to the Board),

and our CEO is limited to one additional public board. You may view a copy of our Guidelines by visiting our website at www.bc.com/investors , selecting the Corporate Governance tab, and then clicking on the Corporate Governance Guidelines link under Governance Documents .

helps inform the Board on decision-making. Commonly discussed topics include macro effects on our business, fundamental demand and supply chain, CEO transition (as needed), board refreshment, corporate governance, executive compensation, capital allocation strategy, risk oversight, sustainability, HCM and sustainability-related issues, including responsible forestry and sourcing practices.

Sustainability, Environmental, and Human Capital Management

Sustainability

The corporate governance and nominating committee is primarily responsible for sustainability matters, and similar to risk oversight, the Board participates in the process and oversight of such strategy. At each meeting, management updates the corporate governance and nominating committee, and the Directors provide guidance on current sustainability topics, including climate and environmental sustainability, and other similar issues that impact the Company. On at least an annual basis, the corporate governance and nominating committee is provided with a more in-depth review of these sustainability topics by either management or a third-party consultant. At each Board meeting, management updates the Board, and the Directors provide guidance on HCM strategies (including employee engagement, growth, fostering a sense of community, and expanding our talent pipeline).

Our Board supports an approach to sustainability matters that is embedded in our Company purpose to bring people, products, and services together to build strong homes, businesses, and communities that stand the test of time. We are a business built on relationships. Our core values guide our actions, unite our employees, and define our brand. We care about relationships with our employees, customers, suppliers, shareholders, and the communities where we live and operate. We strive to foster a connected workplace culture as a way of living our core values of respect and pursuit of excellence, and that creates connection where everyone feels seen, heard, and valued. We further believe it is our responsibility as an employer and community leader to have a positive influence in the communities where we live and operate. Below is a summary of our environmental and human capital efforts; additional information on these initiatives can be found by going to our website www.bc.com and selecting Our Company at the top of the drop- down menu, then Sustainability .

Environmental

Boise Cascade considers environmental responsibility an integral component of our BMD and Wood Products segments. We transform renewable resources, trees, into products that people depend on every day. Our wood products store carbon for years, giving us the opportunity to respond to the effects of climate change through our environmental sustainability practices when procuring and processing wood.

Through sustainable forestry practices, we actively contribute to the responsible use and protection of natural capital, which benefits our employees, customers, shareholders, and the communities where we live and operate. We are committed to responsible forest management principles that help protect and conserve forest habitat and biodiversity. We have rigorous procurement programs to comply with state and provincial laws to protect conservation values and culturally important sites which include measures to protect water quality and conserve wildlife habitat. Further, we are committed to continually achieving compliance with certification standards, employing management practices within our operations to comply with environmental laws and regulations, and promoting sustainable practices. The strength of our sustainable forestry program is annually verified by internal and third-party auditors as part of our continuous improvement efforts.

In addition to using trees, a renewable resource that sequesters carbon, in our manufacturing processes, the Company uses the bark from trees and manufacturing residuals for a significant portion of energy needs in our manufacturing operations. This allows utilization of carbon-neutral energy sources and reduces reliance on energy sources derived from fossil fuels. Using biomass to produce energy also reduces landfill waste, which results in less greenhouse gas (GHG) and methane emissions.

We recognize the scientific evidence indicating a changing climate associated with increasing CO2 in the atmosphere and use the TCFD framework for communicating our position and performance on climate-related matters. To further enhance our ability to track and report on climate-related issues, the Company implemented a comprehensive program to collect material Scope 1 and 2 GHG emissions data and intends to report baseline 2025 emissions data in 2026. This is an important step

24 | Boise Cascade Company 2026 Proxy Statement

TABLE OF CONTENTS

Proxy Statement Summary Corporate Governance and Board Matters Executive Compensation Audit-Related Matters Stock Ownership Information about Our Annual Meeting

in understanding the emissions impact of the Company’s operations and allows us to report climate metrics in the TCFD framework.

The Company engages in pilot programs to explore additional positive climate impacts that can be made through our operations. In 2025, the Company added its first zero-emissions electric truck to its fleet and expanded production of biochar out of wood residuals to use as a carbon-storing soil enhancer by the landscaping industry. Our value of pursuit of excellence guides our climate actions to implement new ideas to drive sustainable results.

Human Capital Management

Human capital management and our ability to attract, develop, and retain talent that embraces our shared values of integrity, safety, respect, and pursuit of excellence have been and will continue to be critical to executing our strategic objectives. The safety of our employees is a core value, and the Company maintains robust safety programs focused on identifying hazards and eliminating risks, as well as safety processes and procedures aimed at eliminating injuries in the workplace. We collect and report common lagging indicators of safety performance, and our safety programs include tools, training, and resources that allow us to collect, analyze, and share leading indicators of safety-related hazards broadly across our organization. We believe that our focus on leading indicators helps to prevent future incidents and injuries. Living our values means driving the expectation that each of our employees has ownership of safety and the authority to stop work if there is a safety concern.

Our Total Rewards program provides competitive pay, comprehensive health benefits, robust financial security resources, paid leave, well-being programs, community engagement opportunities, and career recognition and development. We continually benchmark our offerings and assess our vendor partner performance to ensure our Total Rewards remain competitive.

Embedded in our core values is a focus on our people — building community and growing our people and our business. Selecting and developing talent is a vital aspect of our HCM strategy because we believe our employees are at the heart of our purpose and fulfillment of our promise to our shareholders. We focus on developing talent from within our business segments and supplement that talent with finding the right external hires to support key strategic objectives. Individual development includes annual performance reviews with development plans, access to a variety of learning tools, including self-help resources, and continuing education opportunities. Our employees are able to participate in training through a combination of online platforms and in-person learning. We work towards business continuity and personal leadership growth by developing our employees as individuals through targeted leadership programs, coaching, and focused experiences. The Company’s human resources technology platform reflects ongoing investment in tools that support our employees, enabling learning and performance management, access to pay and tax documents, self-service capabilities, company news, and streamlined document management.

Boise Cascade is invested in broadening our talent pipeline and fostering a connected workplace culture that attracts and retains a talented workforce. We are committed to fostering a workplace culture where everyone feels seen, heard, and valued — one where all employees can contribute their best work to our short- and long-term success. This work starts at the top with our Board and our executive leadership team and provides employee engagement opportunities at all levels. Employees are able to connect with our officers through our open-door policy and have the ability to ask questions to the larger officer team during our quarterly results calls. Further, we encourage and support employees who contribute service hours to boards and nonprofit organizations in the communities where they live and work. These programs encourage the Company’s employees to connect with the community, further improve the Company’s reputation locally, and instill a sense of pride in the workforce.

BOARD STRUCTURE

Board Leadership Structure

	●										●										●
	Chief Executive Officer										Board Chair										INDEPENDENT Lead Independent Director

Currently, the positions of Board chair and CEO are filled separately. Our Board believes that this structure is appropriate for the Company at this time. Our current Board chair’s experience as our former CEO provides our Board with valuable insight on operational and industry issues.

Our corporate governance and nominating committee and our Board have adopted the Guidelines to serve as a flexible framework within which the Board conducts business. The corporate governance and nominating committee and Board routinely review the Guidelines, with the most recent review occurring in February 2026. Because the Board chair is a former CEO of the Company, upon his reelection to the Board, Mr. Matula will fill the lead independent director role. Our lead independent director presides over all meetings of the independent Directors and works collaboratively with our Board chair and CEO regarding Board governance, including the Board evaluation process and establishing meeting agendas for our Board. The lead independent director’s responsibilities include:

●

Leading the Board’s processes for selecting and evaluating new Directors and key management positions

●

Presiding over all meetings of the Board at which the Board chair is not present

●

Serving as a liaison between the Board chair and the independent Directors

●

If requested by major shareholders, ensuring that he or she is available for consultation and direct communication

●

Approving Board and committee meeting agendas and schedules

●

Conducting executive sessions of the independent Directors

●

Overseeing the independent Directors’ annual performance evaluation of the Board chair and the CEO

●

Together with the Board chair, Directors, and the corporate governance and nominating committee, leading the Director recruitment process

●

Calling and chairing meetings of the independent Directors and meetings to retain advisors for the independent Directors

Executive Sessions and Independent Director Sessions

Our Board and our committees routinely meet in executive sessions outside the presence of management. The Board chair presides over the executive sessions of our Board meetings, and each committee chair presides over the executive sessions of each respective committee. Our lead independent director presides over the sessions of our independent Directors, who meet outside the presence of our non-independent Directors at least twice per year.

Independent Directors have direct access to members of management whenever they deem it necessary, and the Company’s executive officers attend at least a portion of each regularly scheduled Board meeting. The independent Directors and all committees are also free to retain their own independent advisors, at the Company’s expense, whenever they feel it would be desirable.

Directors Deferred Compensation Plan

We maintain a nonqualified deferred compensation plan offered to our non-employee Directors (Boise Cascade Directors Deferred Compensation Plan). The plan is an unfunded plan intended to help participants supplement their retirement income while providing them an opportunity to invest a portion of cash compensation. Under the plan, each Director who receives cash compensation for Board service may elect to defer all or a portion of cash compensation in a calendar year. Amounts

deferred are credited with imputed interest at a rate equal to 130% of Moody’s Composite Average of Yields on Corporate Bonds. Participants elect the form and timing of distributions of their deferred compensation balances. Participants may receive a cash payment in a lump sum or in annual installments following their service on our Board. No directors elected to defer cash compensation in 2025 under this plan. We do not anticipate making any changes to this plan in 2026.

Compensation Committee Interlocks and Insider Participation

During 2025, the compensation committee consisted of Mses. Gowland, Humphreys, and Taylor and Messrs. Dawson, Matula, and McGowan. None of our executive officers currently serve, or in

the past year served, as a member of the Board or compensation committee of any entity with one or more executive officers serving on our Board or compensation committee.

EXECUTIVE COMPENSATION

Our board of directors recommends shareholders vote, on a nonbinding advisory basis, FOR the option of an annual vote as the preferred frequency of advisory votes on executive compensation.

Pursuant to Section 14A of the Securities Exchange Act of 1934 (Exchange Act), we are providing our shareholders with the opportunity to cast a nonbinding advisory vote on the frequency with which shareholders will vote to approve, on a nonbinding advisory basis, the overall executive compensation policies and procedures employed by us for our named executive officers. Shareholders will have the opportunity to cast an advisory vote on whether the advisory vote on executive compensation should occur every 1, 2 or 3 years. Shareholders may also abstain from voting on the matter. The proxy card provides shareholders with the opportunity to choose among four options (holding the vote every 1, 2, or 3 years, or abstaining)

and, therefore, shareholders will not be voting to approve or disapprove the recommendation of our Board. We are proposing an annual shareholder vote regarding our executive compensation program because we believe it supports stronger corporate governance by providing an avenue for shareholders to more frequently express their views on our compensation policies and procedures. Your vote is important to us. Although this advisory vote is nonbinding, the compensation committee and our Board will review the results of the vote and take them into account when considering the frequency of the advisory vote on executive compensation.

Our Board recommends shareholders vote, on an advisory basis, FOR the approval of the resolution set forth below approving the compensation of our named executive officers.

Pursuant to Section 14A of the Exchange Act, we are providing our shareholders with the opportunity to cast an advisory vote regarding the compensation of our NEOs. Our compensation philosophy is designed to emphasize a focus on total compensation, with a large portion of our NEOs’ pay being performance-based and considered variable, “at risk,” and aligned with shareholder interests. We seek to pay for performance so that we can recruit and retain the talented employees necessary to drive superior financial and operational results. We view our compensation program as a strategic tool that supports the successful execution of our business strategy and reinforces a performance-based culture. Our Board has agreed to hold this advisory vote on an annual basis, with the next vote following this one expected to occur at the 2027 Annual Meeting of Shareholders.

Shareholders are urged to read the Compensation Discussion and Analysis section in this proxy statement, which discusses how our compensation policies and procedures implement our compensation philosophy. The compensation committee and our Board believe these policies and

procedures are effective in implementing our compensation philosophy and in achieving its goals. Our Board has determined the best way to allow shareholders to vote on our executive compensation is through the following resolution:

RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis , compensation tables, and narrative discussion in this proxy statement, is hereby APPROVED.

Shares will be voted according to shareholder instructions. If no voting instructions are provided, a broker may not vote on the matter. This proposal requires the affirmative vote of the majority of the votes of the shares present in person or by proxy at the meeting of the shareholders and entitled to vote.

Your vote is important to us. Although this advisory vote is nonbinding, the compensation committee and our Board will review the results of the vote. The compensation committee will consider our shareholders’ views and take them into account in making future determinations concerning our executive compensation.

Our Named Executive Officers

This CD&A describes the 2025 compensation program for our executive officers, particularly our NEOs who are listed below. Positions below are those held with the Company as of December 31, 2025:

Nate Jorgensen Chief Executive Officer Jeff Strom Chief Operating Officer Kelly Hibbs Senior Vice President, Chief Financial Officer, and Treasurer Joanna Barney Executive Vice President, Building Materials Distribution Troy Little Executive Vice President, Wood Products

Effective March 3, 2026, after six years of service to the Company as CEO, Mr. Jorgensen retired and Mr. Strom succeeded him as CEO of the Company. The corporate governance and nominating committee interviewed multiple candidates and recommended to the Board that Mr. Strom be elected CEO. For 2026, Mr. Strom will focus on safety, company financial performance, strategic planning, employee engagement, and information technology.

Our Compensation Objectives and Philosophy

1			2			3
We want to attract, retain, and incentivize the management talent we believe is essential to achieving the Company’s strategic objectives, which are to grow the Company prudently and to increase long-term shareholder value.			As a guiding philosophy, we generally target all forms of compensation at the 50th percentile of comparable market compensation data , with appropriate adjustments that take into account each officer’s position, responsibilities, performance, contributions to the Company’s success, level of experience, and other distinguishing qualifications. In some instances, and for the purpose of internal equity, we may establish similar compensation ranges for officer positions with similar scopes of responsibility and other similar qualifications even if such ranges differ from comparable positions at other companies.			We also provide at-risk, performance-based pay opportunities that comprise a significant portion of total compensation opportunity to motivate and reward our executive officers for achieving the Company’s strategic objectives.

We hold annual advisory shareholder votes on executive compensation. Our shareholders have approved our executive compensation with over an average of 96% voting in favor from 2021 through 2025. We believe the strong support demonstrates that shareholders generally view our overall pay program favorably. The compensation committee

and the Board intend to take these advisory votes into account regarding future compensation decisions. For 2026, shareholders will vote on an advisory basis, on the frequency of the vote on executive compensation, and will again vote, on an advisory basis, on whether to approve our executive compensation as set forth in this proxy statement.

Use of Market Data to Determine Amount and Allocation of Compensation

The compensation committee believes that an important criterion for determining the aggregate value of the Company’s compensation program and

the allocation of the value among the various elements of its compensation plans is market data, where available, on the amounts, allocations, and

36 | Boise Cascade Company 2026 Proxy Statement

Proxy Statement Summary Corporate Governance and Board Matters Executive Compensation Audit-Related Matters Stock Ownership Information about Our Annual Meeting

structures utilized by similarly situated peer companies for positions of comparable responsibility.

Management and the compensation committee have utilized compensation and benefits surveys to ascertain market levels of aggregate compensation and the allocation of that compensation among specific compensation elements for its NEOs. Aggregate compensation and compensation for each of the major elements (base salary, target short-term incentive compensation, and target long-term incentive compensation) for the Company’s NEOs has generally been targeted at the 50th percentile of the surveyed peer group companies. However, the specific aggregate compensation (and the allocation among the elements of the total compensation) paid to any of our NEOs may be below or above the 50th percentile target levels, depending on subjective judgments made by the compensation committee based on factors such as the specific officer’s responsibilities that vary from the comparable position, historical performance in the job, tenure with the Company in the position, and other distinguishing qualifications.

Since 2011, the compensation committee has periodically retained the services of FW Cook to prepare a comprehensive analysis of the compensation packages for our NEOs and to compare the specific elements of compensation and the aggregate value with a group of peer companies recommended by FW Cook.

FW Cook conducted a biannual full review of our peer group in 2025 and recommended that our 2025 peer group remove Masonite International Corporation (as it was acquired and no longer discloses compensation data) and add A.O. Smith Corporation, MSC Industrial, and Griffon Corporation to our peer group. The recommended additions were based on an analysis of relative fit from size and business model perspectives, and accounting for the significant and continuing merger and acquisition activity among peers and potential peers. The compensation committee agreed with the recommendation and adopted the following 2025 peer group for 2025 compensation discussions:

	● American Woodmark Corporation			● GMS Inc. (acquired by Home Depot in 2025)
	● A.O. Smith Corporation			● Griffon Corporation
	● Armstrong World Industries			● JELD-WEN Holding, Inc.
	● Beacon Roofing Supply, Inc. (acquired by QXO, Inc. in 2025)			● Louisiana Pacific Corporation
	● BlueLinx Corporation			● MSC Industrial
	● Builders FirstSource, Inc.			● Quanex Building Products Corporation
	● Eagle Materials Inc.			● Simpson Manufacturing Company, Inc.
	● Gibraltar Industries Corporation			● UFP Industries, Inc.

During 2025, the compensation committee reviewed the officer base salaries, the STIP, the LTIP, FW Cook’s fees, and the proposed peer group for 2025 compensation discussions. The

compensation committee also reviewed and reapproved the Company’s compensation philosophy as it appears in this proxy statement.

Summary of Pay Decisions Affecting our NEOs’ Compensation in 2025

For 2025, our compensation committee again granted 50% of the long-term incentive grant value in RSUs and 50% in PSUs. The RSUs vest and are distributed in annual installments over a three-year period. The PSUs, however, are designed to have a

three-year performance target based on ROIC with a three-year cliff vest. The achievement for PSUs is measured in three annual sub-periods; the average achievement for the three years included in the performance period will determine the achievement of the performance factor. This approach to PSUs started in 2024 based on discussions during shareholder engagement sessions and aligns with the long-term interests of shareholders. The STIP is an annual cash-based plan with performance goals based on EBITDA (1) and PRONWC (as defined below in footnote 2 in the table under the heading “ Process Utilized in Setting Strategic STIP Performance Targets ”).

(1)

EBITDA is defined as income before interest (interest expense and interest income), income tax provision (benefit), and depreciation and amortization and is not required by or presented in accordance with generally accepted accounting principles (GAAP) in the United States. Adjusted EBITDA further adjusts EBITDA to exclude the change in fair value of interest rate swaps. Management uses EBITDA and Adjusted EBITDA to evaluate ongoing operations and believes they are useful to investors because they enable them to perform meaningful comparisons of past and present operating results. For a reconciliation of these non-GAAP measures to the most directly comparable GAAP measure (net income), please refer to pages 47-48 of our 2025 Annual Report, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The compensation committee also made salary adjustments for our executive officers in late 2025 to reflect the changing median pay in our peer companies and individual officer performance.

Executive Compensation Elements

The four elements of the Company’s executive compensation program are:

STIP and LTIP awards are intended to comprise a significant portion of each officer’s total compensation opportunity and are designed to motivate and reward our officers for growing the Company and maximizing long-term shareholder

value. Ad hoc discretionary bonuses may be awarded occasionally for exceptional performance but are not a standard element of the Company’s executive compensation structure.

TARGET COMPENSATION PAY MIX

Role of Management in Setting Executive Compensation

As described below, the compensation committee increased the compensation of our officers for 2025. Management did not participate in such decisions. However, the Company’s current CEO makes, and in 2025 the Company’s former CEO made, recommendations to the compensation committee with respect to base salaries and performance targets for the STIP and LTIP for officers other than himself. The compensation committee makes all decisions regarding each NEO’s base salary, LTIP and STIP targets, the overall performance targets of the plans, and the potential and actual payouts under each plan.

Under the omnibus stock plans (the 2016 Omnibus Incentive Plan and the 2025 Omnibus Incentive Plan), the Company has the ability to clawback all equity awards, both time-based and performance-based, upon various events including upon misconduct related to a restatement. Additionally, awards granted under the STIP and the LTIP (both time-based and performance-based) are subject to our Executive Compensation Clawback Policy and our Misconduct Clawback Policy. Our Executive Compensation Clawback Policy requires us to recoup such awards received on or after October 2, 2023 in the event of a financial restatement due to material noncompliance with a financial reporting

requirement under U.S. federal securities laws that would have resulted in lower payments based on the restated results. Our Misconduct Clawback Policy permits us to recoup such awards if, (i) as a result of a financial restatement, the award would have been lower had the financial results been properly calculated when originally reported, (ii) an award was predicated on achieving financial results that were subsequently determined to be due to a fraudulent act by the officer or (iii) an officer engaged in misconduct, including misconduct that results in reputational or financial harm to the Company, even if such misconduct does not result in a financial restatement. Misconduct includes an individual’s fraud or willful misconduct that results in reputational or financial harm to the Company, an individual’s material violation of law or the Company’s compliance and ethics-related policies or procedures, or an individual’s failure to appropriately supervise Company personnel. Both our Misconduct Clawback Policy (both time-based and performance-based) and our Executive Compensation Clawback Policy (performance-based only) apply to incentive-based compensation received during a three-year lookback period. Our Misconduct Clawback Policy applies to the extent not superseded by our Executive Compensation Clawback Policy.

Base Salary

Our compensation committee has historically reviewed base salaries for our NEOs on an annual basis and at the time of promotions or other changes in responsibilities. Consistent with past practice, in late 2025, the compensation committee approved general base salary increases for the NEOs to

continue to move them, as determined appropriate, toward the 50th percentile based upon FW Cook’s 2025 study. The November 2025 increases in NEO salaries averaged 6.94% and were in line with market data provided by FW Cook. The 2024 and 2025 base salaries and increases are listed below:

The compensation information for Mr. Strom contained herein reflects 2025 compensation, not the increase for his promotion to CEO in 2026.

(2)

Mr. Strom was promoted to Chief Operating Officer on January 20, 2025 and was awarded a salary increase at the time of his promotion.

(3)

Ms. Barney became a named executive officer in 2025.

Short Term Incentive Plan

The STIP is designed to recognize and reward the contributions that our NEOs and other participants make to the Company’s annual performance. Payout under the STIP is based on achievement of performance measures that are tied to the Company’s annual financial performance. We offer this plan to encourage and reward conduct that will lead to better performance of our businesses as measured by the performance criteria. Each NEO’s participation in the plan, along with the criteria for calculation of the payout, is established annually by our compensation committee and communicated to the participants in a STIP award notice. A determination of the amount payable under the plan based on actual performance is made by the compensation committee generally in February of the following year, and resulting payments or awards are then made to participants.

The actual STIP awards may be less than or greater than the target incentive amounts depending on

the achievement of pre-determined financial goals and performance objectives and the exercise of the compensation committee’s discretion.

For 2025, the compensation committee set a threshold of 25% of the target award as the minimum award to be granted under the program. If performance is below this threshold, no STIP payout is earned. The compensation committee also set a maximum of 225% of the target award and approved a payout graph with a payout line whereby once the level of performance is determined the award multiplier can be determined. The dollar amount of the threshold, target, and maximum award payable to each of our NEOs is set out in the table found under “ 2025 Grants of Plan-Based Awards ” in this section of this proxy statement.

2025 STIP Compensation

For 2025, each of our NEOs participated in the STIP. The plan provided for awards to be determined based on the extent to which the financial goals and performance objectives were met during the year.

Process Utilized in Setting Strategic STIP Performance Targets

The compensation committee employs a rigorous process to review the annual budget that promotes

the Company’s strategic objectives and forms the basis for establishing the STIP performance targets.

Furthermore, the compensation committee takes into account Company-specific and industry outlook for the year, historical and projected growth rates for the Company as well as peers and external expectations and guidance.

The performance metrics established by the compensation committee under our 2025 STIP were based on forecasts of 1.35 million U.S. housing

starts, a primary demand driver in our business. In setting the STIP target in February 2025, the compensation committee evaluated forecasted earnings for 2025, and market and industry conditions including home affordability, the potential impact of tariffs, and uncertainty broadly across the U.S. economy. As such, the compensation committee expected a deceleration in housing starts compared with actual housing starts of 1.37 million in 2024 and 1.42 million in 2023. In addition, in 2025, the Company expected continued price erosion for our EWP products due to slowing

economic activity and decreased demand for new residential construction. The compensation committee set the STIP target at a level intended to drive meaningful performance while balancing concerns for expected pricing and volume impacts. The annual incentive target awards, financial goals, and performance objectives required for each NEO participating in the STIP for 2025 are set forth below. Actual payouts are also shown. No discretion was exercised by the compensation committee in awarding payouts for 2025.

Corporate EBITDA shown is based on the financial performance of Adjusted EBITDA, which reflects normal recurring adjustments made, such as the change in fair value of interest rate swaps, as disclosed in our detailed calculation of Adjusted EBITDA. The calculation of EBITDA and Adjusted EBITDA is described on page 38 of the proxy statement.

Pre-tax Return on Net Working Capital (PRONWC) is calculated based on GAAP amounts by dividing BMD’s net operating income by the average net working capital reported as of each month-end during a 13-month period running from December 2024 through December 2025. The compensation committee includes PRONWC as a portion of Ms. Barney’s performance criteria because it reflects BMD’s control of working capital, which is a critical financial measure in our distribution business.

2025 Ad Hoc Discretionary Bonus Awards

From time to time, the compensation committee may elect to grant a discretionary bonus to one or more of the NEOs or to other employees to recognize and reward exemplary performance providing value to the Company beyond what is recognized by the structure of the STIP. A formal plan does not

govern these bonus payments, and no NEO has any contractual entitlement or expectation of any such payment. The amount and timing of the grant of any such bonus to NEOs are determined by the compensation committee at its sole discretion. No such bonuses were awarded in 2025 to the NEOs.

Long Term Incentive Plan

We make grants of RSUs and PSUs under our long- term equity-based award agreements (LTIP), which grants prior to May 1, 2025 were made under the 2016 Omnibus Incentive Plan and grants thereafter were made under the 2025 Omnibus Incentive Plan. Both plans permit grants of stock options, stock appreciation rights (SARs), restricted stock, other stock- based awards, other cash-based compensation, and performance awards. The purpose of the LTIP is to provide incentives that

will attract, retain, and motivate high-performing officers, Directors, employees, and consultants by providing them a proprietary interest in our long-term success or compensation based on their performance in fulfilling their responsibilities to our Company. The LTIP is administered by our compensation committee.

Awards granted under the LTIP are subject to our recoupment policies.

2025 LTIP Compensation

In February 2025, the compensation committee approved equity grants under the 2016 Omnibus Incentive Plan to our NEOs. The amount and structure of the grants were based on the recommendations FW Cook made as a result of the study they conducted on behalf of the compensation committee. Officer participants received two types of equity grants: RSUs and PSUs. The compensation committee set a dollar amount for each participant to calculate the target RSU and PSU grants on the day of the award after market close. Half of the value of the target award was granted in RSUs. The other half of the target award was granted in PSUs.

The RSUs awarded in 2025 vest over a three-year period with one-third vesting on March 1 of each of 2026, 2027, and 2028 with share distribution the

following trading day. The PSUs awarded at target are adjusted by a performance factor determined by the performance objectives described below and may be further adjusted at the discretion of the compensation committee. The performance- adjusted PSUs granted in 2025 vest in a single installment on March 1, 2028, with share distribution the following trading day. Vesting of PSUs and RSUs is subject to an officer’s continued employment with the Company, with certain limited exceptions described below.

The 2025 LTIP awards were based on the closing market value on February 28, 2025 (the trading day immediately preceding the grant date of March 1, 2025, which was a Saturday) of $103.66 and are as follows:

	Financial Goal PSUs			Threshold 50% of PSUs						Target 100% of PSUs						Maximum 200% of PSUs
	Company ROIC (1)					7.5%						12.5%						24.0%

ROIC is calculated as described on page 9 of this proxy statement.

The compensation committee chose ROIC as the performance metric in the LTIP to differentiate from the EBITDA measure used in the STIP because it believed ROIC would put a focus on short-term and long-term investments and reinforce the importance of shareholder returns. Based on the market conditions and the nature of the products we distribute and manufacture, the compensation committee supports the plan design and believes a three-year performance period better aligns management with the long-term interests of our shareholders.

In 2025, the PSUs awarded are earned based on three-year ROIC performance established by the compensation committee and are subject to a three-year cliff vest. Achievement over the three-year performance period is measured in annual sub-periods based on ROIC for 2025, 2026, and 2027. The average achievement for the three years in the performance period will determine the number of earned PSU’s. At average threshold performance, 50% of the target PSUs are earned, and at average maximum performance, 200% of the target PSUs are earned. The compensation committee approved a payout scale such that when results fall between the threshold and maximum reference points, interpolation is used to determine the actual PSUs to be awarded.

Vesting of LTIP awards is subject to an NEO’s continued employment through the vesting date, except in certain limited circumstances. If an NEO dies or becomes disabled,

(i)

all unvested RSUs become vested, and

(ii)

all earned PSUs for which the performance metric is satisfied become vested at that amount. In the event the performance period applicable to the PSUs has not elapsed at the time of such death or disability, the PSUs will vest based on actual achievement of the performance metric.

In the event of an NEO’s eligible retirement,

(i)

unvested RSUs become vested as to 1/3 of the award, multiplied by a pro rata portion based on the number of full calendar months that have elapsed during the then 12-month vesting period prior to retirement, divided by 12, and

(ii)

earned PSUs become vested as to a pro rata portion based on the number of full calendar months that has elapsed during the vesting period prior to retirement, divided by 36.

Payout occurs on the normally scheduled payout date for the PSU awards, and upon retirement for the pro rata RSU awards. For purposes of LTIP vesting, the definition of retirement means the NEO’s termination on the earlier of: the calendar year in which the NEO attains age 62 and completion of at least ten years of employment with the Company and its predecessors, or age 65 and completion of at least five years of employment with the Company. This definition applies to LTIP awards granted on or after March 1, 2024. For all outstanding awards granted prior to this date, the definition of retirement remains unchanged from that described in the applicable grant agreement. Beginning in 2024, LTIP grant agreements provide that in the event an NEO continues to serve as or is appointed as a member of the Company’s Board immediately following termination of employment, unvested RSUs and PSUs will continue to vest and become payable as if the NEO remained employed by the Company for as long as the NEO continues to serve as or is appointed as a member of the Company’s Board immediately following termination of employment, unvested RSUs and PSUs will continue to vest and become payable as if the NEO remained employed by the Company for as long as the NEO continues to serve as a member of the Company’s Board. This change was implemented to recognize that as a member of the Company’s Board, former executives will continue to have a role in the success of the company.

In the event of a change in control in which the LTIP awards are not replaced by an equivalent award,

(i)

RSUs become vested and

(ii)

earned PSUs become vested, with the number of earned PSUs determined based on actual performance for already completed annual sub-periods in the performance period and at target for incomplete annual sub-periods.

Other Compensation and Benefit Plans

The Company’s NEOs receive additional compensation under a few other compensation and benefit plans, as further described below. These plans and benefits, except those that are frozen or closed to new entrants, are provided to create an aggregate compensation and benefits package that is competitive in the marketplace, thereby helping us to attract and retain the management talent needed to achieve the Company’s strategic objectives.

Boise Cascade Supplemental Pension Plan

On December 31, 2009, the compensation committee froze our nonqualified Boise Cascade Supplemental Pension Plan (SUPP) in which Messrs. Hibbs and Little participated. The benefits accrued will be paid from the Company’s general assets. The aggregate, present value of the pension benefits as of December 31, 2025, for each of our NEOs who are participants in the SUPP are disclosed in the table found under the heading “ 2025 Supplemental Pension Benefits ” following this CD&A.

Boise Cascade Company Savings Plan

The Company maintains a 401(k) defined- contribution savings plan for U.S. employees, including its NEOs. Under the plan, eligible employees electing to participate may contribute up to 50% of their pretax income, subject to Internal Revenue Service (IRS) rules limiting an individual’s total contributions and the application of IRS tests designed to ensure that the plan does not discriminate in favor of highly compensated employees.

Since January 2013, we have generally provided company contributions to the savings plans. For salaried employees and employees not covered by a collective bargaining agreement who are paid on an hourly basis that are not in an hourly production position within the Wood Products segment, for each pay period we contribute an amount equal to 4% of the employee’s eligible wages (base salary and short-term incentive compensation) for the period. If the Company’s EBITDA meets or exceeds targets specified by the compensation committee and the Board, the Company is able to make additional discretionary contributions in an amount

up to 2%, 3%, or 4% of the employee’s wages, depending on the affected employee’s number of years of service. For 2025, the compensation committee and the Board set an Adjusted EBITDA minimum performance threshold of $200 million and maximum of $450 million. The Company approved a payout scale so that when performance falls between the threshold and maximum levels linear interpolation is used to determine the actual award. Amounts in excess of IRS annual limitations on the amount of income on which Company contributions may be made to qualified defined contribution retirement plans are paid to participants as taxable cash compensation and/or credited to the participant’s deferred compensation account. In 2025, the Company’s Adjusted EBITDA performance was $342.2 million. All of our NEOs participate in the plan.

Amounts deferred under this plan by the NEOs are included in the salary disclosure in the “ Summary Compensation Table ,” and amounts contributed by the Company to the account of an NEO under the plan are included in the “ All Other Compensation ” column in the “ Summary Compensation Table .”

Nonqualified Deferred Compensation Plan

Under the Boise Cascade Company Deferred Compensation Plan, participating employees irrevocably elect each year to defer receipt of a portion of their base salary and incentive compensation. A participant’s account is credited with an amount equal to what the Company’s 401(k) contribution would have been if the money had not been deferred under the 401(k) plan rather than the deferred compensation plan and with imputed interest at a rate equal to 130% of Moody’s Composite Average of Yields on Corporate Bonds. Participants may receive payment of their deferred compensation plan balance in a lump sum or installments over a specified period of years following the termination of their employment with the Company or can elect distributions of in-service account deferrals prior to termination, as specified in the plan. Amounts deferred under this plan in any relevant year or contributed to the account under the plan by any of our NEOs are disclosed in the “ 2025 Nonqualified Deferred Compensation ” table.

Agreements with Named Executive Officers

The Company does not have employment agreements with any of its NEOs other than the severance agreements described in this section.

In 2022, the Company entered into new severance agreements with each of the NEOs to maintain operating continuity in the event of a change of control. The severance agreements generally are effective until January 31st of the following year, except that if the Company does not give notice of non-extension 60 days prior to expiration, the term of each severance agreement will be automatically extended for an additional year.

The severance agreements for the NEOs provide that in the event of a “qualifying termination” (meaning any termination with the exception of a termination (i) by the Company for cause or disability; (ii) by the NEO other than for good reason (as described in the severance agreement); or (iii) as a result of the NEO’s death), the NEO will be entitled to receive (a) their full base salary through the date of termination, a STIP payment for the year of termination based on the plan’s actual payout for the year and pro-rated to reflect the portion of the year expired prior to termination, and all other compensation to which he or she is then entitled; (b) a lump-sum severance payment equal to two times the sum of (i) the NEO’s annual base salary plus (ii) target STIP for the year in which the termination occurs; (c) a lump-sum amount equal to the value of such NEO’s unused and accrued time off, less any advanced time off, in accordance with

the applicable time-off policy in effect on the termination date; and (d) a lump sum payment equal to 18 times the monthly Company-paid premium amount for all life, disability, accident, and healthcare plans, programs, or arrangements.

In the event of a change in control, the agreements require a second trigger of a qualifying termination from employment before benefits are payable.

The severance agreements provide that in the event of a non-qualifying termination, the NEO will be entitled to receive their full base salary through the date of termination, plus all other compensation to which they are then entitled. In the event of a failure to perform duties as a result of incapacity due to physical or mental illness or injury, the NEO will be entitled to continue to receive the full base salary until such time as employment is terminated due to disability. No severance payments or continuation of healthcare benefits beyond the date of termination are provided for under such circumstances.

In consideration of the severance payments described above, each severance agreement contains confidentiality, non-solicitation, and non- disparagement provisions, and a general release of all claims against the Company and its affiliates, as a condition of payment of benefits under the severance agreement.

The amounts reported in this column (with the exception of any amounts that are not above-market earnings) have been reported for applicable years in the “Summary Compensation Table.”

Potential Payments upon Termination or Change in Control

The following table reflects an estimate of the compensation the Company would have been required to pay to each of its NEOs under the compensation plans, contracts, agreements, and arrangements between each such individual and the Company for:

●

Voluntary termination with good reason or involuntary termination by the Company without cause;

●

A change in control without adoption of a replacement plan or assumption of the existing obligations under plans; or

●

Death or disability, as applicable.

The amounts shown assume that such termination or change in control was effective as of December 31, 2025. The actual amounts the Company would have been required to pay on other dates may be determined only at the time of separation from the Company or the change in control and will accordingly vary from those disclosed here, which are based on a hypothetical December 31, 2025 termination. The amounts disclosed here do not include amounts earned by the NEO through that time as base salary, any bonuses approved by the compensation committee prior to that date, and payments earned prior to

that date, such as 2025 awards earned pursuant to our STIP, because neither their amount nor the timing of the payment is affected by the fact or the nature of the termination of employment. In addition, the disclosure does not include amounts payable pursuant to the 401(k), deferred compensation, or pension plans, which are disclosed elsewhere in the CD&A in this proxy statement, and accompanying tables.

The availability of severance payments and continued healthcare and insurance benefits beyond termination of employment is contractually conditioned for each of our NEOs on their provision to the Company of a release of claims arising from their employment and the termination thereof and their performance of contractual confidentiality, non-solicitation, and non-disparagement obligations contained in their severance agreements with the Company, as well as payment of applicable contributions for healthcare and insurance benefits. The payments described in the tables and textual materials that follow are provided by severance agreements and the terms of the LTIP. For a description of these contractual arrangements, see “ LTIP Compensation ” and “ Agreements with Named Executive Officers ” in the CD&A in this proxy statement.

Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd Frank) and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the CEO total compensation of Nate Jorgensen.

For 2025, our last completed fiscal year:

●

The annual total compensation of our median employee (excluding our CEO and our employees in Canada) was $64,782; and

●

The total compensation of our CEO was $7,236,278 based on the 2025 amounts reflected in the “ Summary Compensation Table ”.

Based on this information, we estimate that the annual total compensation of our CEO was approximately 111.7 times that of our median employee in 2025.

We identified our median employee by preparing a list of all our employees (excluding our CEO and our employees in Canada) as of December 31, 2025. We then collected the information necessary to calculate Medicare taxable income for the year ended December 31, 2025, as will be reported to the IRS on Form W-2 for the employees included in such list.

We did not include our employees in Canada in determining our median employee, as they accounted for less than 5% of our total employee population as of December 31, 2025. As of December 31, 2025, we had a total of 7,652 employees, comprised of 7,555 U.S.-based employees, and 97 employees in Canada.

	Location			# of Employees						% of Total							Total # of Employees
	U.S.					7,555						98.7%							7,652
	Canada					97						1.3%

The pay ratio included above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and the methodology described above. The SEC rules for identifying the median-compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

Mr. Jorgensen was the CEO (PEO) for all five fiscal years.

(2)

The Non-PEO NEOs for whom the average compensation is presented in this table are for fiscal 2025, Messrs. Strom, Hibbs, and Little, and Ms. Barney; for fiscal 2024, Messrs. Hibbs, Little, and Strom, and Ms. Twedt; for fiscal 2023 and 2022, Messrs. Hibbs, Brown, and Strom, and Ms. Twedt and for fiscal 2021, Messrs. Hibbs, Rancourt, Brown, and Strom and Ms. Twedt.

(3)

The amounts shown in the “Compensation Actually Paid to PEO” and “Average Compensation Actually Paid to Non-PEO NEOs” columns have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the PEO and the Non-PEO NEOs. These amounts reflect the “Total” column of the “Summary Compensation Table” for the applicable fiscal year with certain adjustments as described in footnote 4.

(4)

“Compensation Actually Paid to PEO” and “Average Compensation Actually Paid to Non-PEO NEOs” columns reflect the deductions and adjustments of certain amounts for the PEO and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the “Deduction to Stock Awards” column below are the amounts from the “Stock Awards” column set forth in the “Summary Compensation Table”. Amounts in the “Deduction to Change in Pension Value” column below reflect the change in pension value included in the “Change in Pension Value/Nonqualified Deferred Compensation Earnings” column reported in the “Summary Compensation Table”. Amounts in the “Adjustment to Pension Service Cost” column below are based on the service cost for services rendered during the listed year.

(5)

The peer group used for this total shareholder return (TSR) calculation is comprised of the S&P 600 Building Products Index. This is the same peer group as reported in the Company’s Form 10-K for 2025. The peer group TSR is weighted according to the index’s stock market capitalization on December 31, 2019. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the index, respectively, and assumes dividends were reinvested in the Company’s stock. Historical stock performance is not necessarily indicative of future stock performance. Beginning in 2023, the Company transitioned to the S&P 600 Building Products Index as the peer group for the TSR calculation. This change in peer group was to better reflect the industry in which we compete, as the S&P 600 Building Products Index represents small capitalization building products industry performance.

(6)

EBITDA is calculated as set forth on page 38 of the proxy statement.

AUDIT-RELATED MATTERS

Our Board recommends shareholders vote FOR the ratification of the appointment of KPMG as our independent registered public accounting firm for the year ending December 31, 2026.

The audit committee of our Board is responsible for the engagement of our independent auditor and has appointed KPMG in that capacity for the fiscal year ending December 31, 2026.

Although ratification is not required by our bylaws or otherwise, our Board is submitting the selection of KPMG to our shareholders for ratification because we value our shareholders’ views on our independent registered public accounting firm. If the appointment of KPMG is not ratified, the audit committee will evaluate the basis for the shareholders’ vote when determining whether to continue the firm’s engagement, but the audit committee may ultimately decide to continue the engagement of the firm or another audit firm without resubmitting the matter to shareholders. Even if the selection of KPMG is ratified, the audit committee may, in its sole discretion, change the appointment at any time during the year if it

determines a change would be in the best interests of the Company and our shareholders.

It is expected that one or more representatives of KPMG will be available online at the 2026 Annual Meeting to answer questions. They will also have the opportunity to make a statement if they desire to do so.

For information on the services KPMG provided for us in 2025, please refer to the audit committee report at page 60 .

Shares will be voted according to shareholder instructions. This proposal is considered a routine matter with respect to which a broker or other nominee can generally vote in their discretion. Therefore, no broker non-votes are expected in connection with this proposal. This proposal requires the affirmative vote of the majority of the votes of the shares present in person or by proxy at the meeting of the shareholders and entitled to vote.

Quorum

A quorum is necessary to hold a valid meeting. A quorum will exist if shareholders holding a majority of the shares of our common stock outstanding and entitled to vote at the Annual Meeting are present online or by proxy. Shareholders have no right to cumulative voting as to any matter, including the election of Directors. Abstentions and broker non-votes will be treated as shares of common stock that are present and entitled to vote for purposes of determining the presence of a

quorum. A broker non-vote occurs when a broker does not have discretionary voting power for that particular item and has not received voting instructions from the beneficial owner. Brokers do not have discretionary voting power on non-routine matters. Proposal No. 4, the ratification of the appointment of our independent registered public accounting firm for the year ending December 31, 2026, is the only routine matter for consideration at the Annual Meeting.

Independent Tabulator

We have appointed Broadridge Financial Solutions Inc. (Broadridge) as our independent tabulator to receive and tabulate all votes cast at the annual

meeting. Broadridge will determine whether a quorum is present.

The Company participates in “householding” of proxy materials unless the Company has received contrary instructions from one or more security holders. This means that only one copy of our proxy materials or Notice of Internet Availability of Proxy Materials may have been sent to multiple shareholders in your household. We will promptly deliver a separate copy of such documents to you if you contact the Broadridge Householding Department at the following address:

Broadridge Householding Department 51 Mercedes Way Edgewood, NY 11717

Toll-Free Number: 1-800-542-1061

If you want to receive multiple copies of our proxy materials or Notice of Internet Availability of Materials in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker, or other record holder, or you may contact the Broadridge Householding Department at the address and phone number shown.

Shareholder Proposals for Inclusion in Next Year’s Proxy Statement

According to SEC rules, to be considered for inclusion in next year’s proxy statement, shareholder proposals for the 2027 Annual Meeting of Shareholders must satisfy all applicable requirements of Rule 14a-8 under the Exchange Act and be received by our corporate secretary at the address shown below no later than November 17, 2026:

Boise Cascade Company Attention: Corporate Secretary 1111 West Jefferson Street, Suite 300 Boise, ID 83702

Additionally, for a shareholder to bring other business, before our 2027 Annual Meeting of Shareholders, including any nominations for Director, our bylaws require that our corporate secretary must receive notice at the above address of any such business or nominations for Director no earlier than December 31, 2026, and no later than January 30, 2027.

Please refer to Article II, Section 11 of our bylaws for an outline of the information a shareholders’

notice must include regarding nominations for Directors and other business to be brought before a shareholders’ meeting. For proposals or nominations that are not timely filed, we retain discretion to vote proxies we receive, provided that

(a)

we include in our proxy statement advice to the shareholders on the nature of the proposal and how we intend to direct our voting discretion and

(b)

the proponent does not issue a separate and appropriate proxy statement.

In addition to satisfying the foregoing requirements under our bylaws with respect to advance notice of any nominations for Director, shareholders who intend to solicit proxies in reliance on the SEC’s universal proxy rule must comply with the additional requirements of Rule 14a-19(b) under the Exchange Act.
