THIS PERFORMANCE STOCK UNIT AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date above, is entered into by and between Boise Cascade Company, a corporation organized in the State of Delaware (the “Company”), and the Participant specified above, pursuant to the 2016 Boise Cascade Omnibus Incentive Plan (the “Plan”). This Agreement is not enforceable until you accept the Agreement electronically. Electronic acceptance constitutes your acknowledgment of receipt of the Award and your agreement to the terms of the Agreement.

1.Incorporation by Reference; Plan Document Receipt. This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments to the Plan adopted at any time unless such amendments are expressly intended not to apply to this Agreement), and the terms and provisions of the Plan are made a part of and incorporated in this Agreement as if they were set forth in this Agreement. Any capitalized term not defined in this Agreement shall have the meaning given in the Plan. The Participant acknowledges receipt of a copy of the Plan and that he or she has read the Plan carefully and fully understands it. If there is any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan control.

2.Grant of Performance Stock Unit Award. The Company grants to the Participant, as of the Grant Date, the number of PSUs specified above, as adjusted pursuant to Section 3(a). Except as otherwise provided by the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection against potential future dilution of the Participant’s interest in the Company for any reason. No adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of the shares of Common Stock underlying the PSUs, except as otherwise specifically provided for in the Plan or this Agreement.

3.Vesting. The PSUs subject to this Award are subject to both a time-based vesting condition (the “Time-Based Condition”) and a performance-based vesting condition (the “Performance Condition”). None of the PSUs shall vest unless and until both the Time-Based Condition and the Performance Condition are satisfied.

a.Performance Condition. The Performance Condition is based upon the Company’s ROIC for the 2024, 2025, and 2026 calendar years (the “Performance Period”). Following the end of the Performance Period, but in no event later than March 1, 2027, the Committee shall determine the percentage of Target PSUs that are earned ( the “Earned PSUs”) based on the following formula. Following the end of each calendar year included in the Performance Period, the Committee shall certify the Company’s ROIC for that calendar year and, based on the level of ROIC achieved in the table below, shall determine the Percentage of Target PSUs for that year. The average of the Percentage of Target PSUs for each of the three years included in the Performance Period will be considered the Earned PSUs. For example, if the ROIC achieved for 2024 is [max %], and the ROIC achieved for 2025 is [target %] and the ROIC achieved for 2026 is [target %], then the Earned PSUs will be 133.33% of Target PSUs.

i.For each calendar year included in the Performance Period, the Percentage of Target PSUs for the actual annual ROIC between the Threshold level and the Target level or between the Target level and the Maximum level shall be determined on a pro rata basis using straight line interpolation. If the average actual ROIC for the Performance Period

iii. Change in Control. If a Change in Control occurs during the Performance Period, then the number of Earned PSUs shall equal the number of Target PSUs; provided however that this Section 3(a)(iii) shall not apply if the PSUs are replaced by an equivalent award providing for accelerated vesting in connection with the Participant’s termination from employment or service with the Company (“Termination”) following the Change in Control, as determined by the Committee in its sole discretion.

i. Vesting Date. Earned PSUs will satisfy the Time-Based Condition and vest on March 1, 2027 (the Vesting Date). Except as otherwise provided in this Section 3(b), a Participant must be employed on the Vesting Date to vest in the Earned PSUs. If a Participant incurs a Termination prior to the Vesting Date other than as provided in this Section 3(b), all Earned PSUs will be forfeited immediately following the Participant’s Termination.

iii. Change in Control. If a Change in Control which constitutes a “change in the ownership of the corporation,” a “change in effective control of the corporation,” or a “change in the ownership of a substantial portion of the assets of the corporation,” as those terms are defined pursuant to Section 409A of the Internal Revenue Code and the regulations thereunder, occurs prior to the Vesting Date, then the Time-Based Condition shall be satisfied for all Earned PSUs as of the date of the Change in Control and the Earned PSUs shall vest as of the date of the Change in Control, so long as the Participant has not incurred a Termination prior to the Change in Control; provided that this Section 3(b)(iii) shall not apply if the PSUs are replaced by an equivalent award providing for accelerated vesting in connection with the Participant’s Termination following the Change in Control, as determined by the Committee in its sole discretion.

iv. Termination due to death or Disability. In the event of a Participant’s Termination due to death or Disability during the Performance Period, then the Time-Based Condition shall be satisfied as of the date of death or Disability for all PSUs and the PSUs shall remain outstanding and shall have the opportunity to satisfy the Performance Condition and become Earned PSUs. In the event of a Participant’s Termination due to death or Disability after the Performance Period, the Time-Based Condition shall be satisfied as of the date of death or Disability for all Earned PSUs.

v. Termination due to Retirement. In the event of a Participant’s Retirement at any time prior to the Vesting Date, a pro rata portion of the Earned PSUs shall be deemed to have satisfied the Time-Based Condition as of the later of March 1, 2025 or the Participant’s Retirement date. The pro rata portion shall be calculated as the number of Earned PSUs multiplied by a fraction, the numerator of which is the number of full calendar months elapsed from March 1, 2024 through the Participant’s Retirement date, and the denominator of which is 36. For purposes of this Agreement, “Retirement” means the Participant’s Termination on the earlier of: the calendar year in which the Participant attains age 62 and has completed at least 10 years of employment with the Company and its predecessors, or the calendar year in which the Participant attains age 65 and has completed at least 5 years of employment with the Company and its predecessors.

vi. Retention as a Non-Employee Director. If the Participant continues to serve as or is appointed as a member of the Company’s Board of Directors immediately following Termination, PSUs shall continue to vest and become payable as if the Participant remained employed by the Company for as long as such Participant continues to serve as a member of the Company’s Board of Directors. Any decision to retain a Participant as a member of the Company’s Board of Directors shall be determined by the Board of Directors (and recommended by the Corporate Governance & Nominating Committee).

b.Time of Payment. The designated payment date for purposes of Section 409A of the Internal Revenue Code and the regulations thereunder shall be March 1, 2027 for Earned PSUs vesting pursuant to Section 3(b)(i), Section 3(b)(v), and Section 3(b)(vi); the date of Change in Control for Earned PSUs vesting pursuant to Section 3(b)(iii); and the date of death or Disability for Earned PSUs vesting pursuant to Section 3(b)(iv). Delivery of shares pursuant to this Agreement shall be made as soon as practicable following the designated payment date, and in any case by the later of December 31st of the calendar year in which such designated payment date occurs or the 15th day of the third calendar month following the designated payment date.

5.Dividends; Rights as Stockholder. Cash dividends on shares of Common Stock underlying the PSUs shall be credited to a dividend book entry account on behalf of the Participant, provided that any cash dividends shall be held uninvested and without interest, shall be subject to the same vesting conditions as the PSUs to which they relate, and shall be paid in cash at the same time that the shares of Common Stock underlying the Vested PSUs (if any) are delivered to the Participant in accordance with Section 4. Stock dividends on shares of Common Stock underlying the PSUs shall be credited to a dividend book entry account on behalf of the Participant, provided that any stock dividends shall be subject to the same vesting conditions as the PSUs to which they relate, and shall be paid in shares of Common Stock at the same time that the shares of Common Stock underlying the Vested PSUs (if any) are delivered to the Participant in accordance with Section 4. The Participant shall have no rights as a stockholder with respect to any shares of Common Stock underlying any PSU unless and until the Participant has become the holder of record of such shares.

6.Non-Transferability. No portion of the PSUs (or the shares of Common Stock underlying the PSUs) may be sold, assigned, transferred, encumbered, hypothecated or pledged by the Participant, other than to the Company as a result of forfeiture of the PSUs as provided in Section 3, unless and until the shares are delivered to the Participant in accordance with Section 4 and the Participant has become the holder of record of the shares.

7.Governing Law. All questions concerning the construction, validity and interpretation of this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to choice of law provisions.

8.Tax Withholding. The Company may deduct or withhold, or require the Participant to remit to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the PSUs. If the Participant fails to remit any amounts requested by the

Company, the Company may otherwise refuse to issue or transfer any shares of Common Stock otherwise required to be issued pursuant to this Agreement. The Participant acknowledges that if he or she is or becomes Retirement-eligible or Retires prior to the Vesting Date, FICA and SDI obligations may apply prior to any payment pursuant to Section 4. Any minimum statutory required withholding obligation with regard to the Participant shall be satisfied by reducing the amount of cash or shares of Common Stock otherwise deliverable to the Participant.

a.The Participant has been advised that the Participant may be an “affiliate” within the meaning of Rule 144 under the Securities Act and in this connection the Company is relying in part on the Participant’s representations set forth in this Section 9.

b.If the Participant is deemed an affiliate within the meaning of Rule 144 of the Securities Act, the shares of Common Stock issuable hereunder must be held indefinitely unless an exemption from any applicable resale restrictions is available or the Company files an additional registration statement (or a “re-offer prospectus”) with regard to such shares of Common Stock and the Company is under no obligation to register such shares of Common Stock (or to file a “re-offer prospectus”).

c.If the Participant is deemed an affiliate within the meaning of Rule 144 of the Securities Act, the Participant understands that (i) the exemption from registration under Rule 144 will not be available unless (A) a public trading market then exists for the Common Stock of the Company, (B) adequate information concerning the Company is then available to the public, and (C) other terms and conditions of Rule 144 or any exemption therefrom are complied with, and (ii) any sale of the shares of Common Stock issuable hereunder may be made only in limited amounts in accordance with the terms and conditions of Rule 144 or any exemption therefrom.
