WHEREAS, Puishys has served as the Chief Executive Officer (“CEO”) of Apogee and a member of the Board of Directors of Apogee (the “Board”) since August 2011;

WHEREAS, Puishys has announced to the Board his intention to retire from Apogee on February 27, 2021;

WHEREAS, the Board wants to recognize Puishys’ many years of loyal service to Apogee and to provide for the smooth transition of the CEO position;

WHEREAS, the parties desire to set forth all matters regarding Puishys’ retirement as CEO; and

WHEREAS, the Board believes it is in the best interests of Apogee’s shareholders to enter into this Agreement.

NOW THEREFORE, in consideration of the premises and the covenants herein, the sufficiency of which is hereby acknowledged, Puishys and Apogee agree as follows:

1.    Retirement as CEO. Effective on February 27, 2021 (the “Retirement Date”), Puishys shall retire as Apogee’s CEO and as a member of the Board and from all other officer positions he currently holds with Apogee and its affiliates and from all director positions he holds with Apogee’s affiliates. In the event that Puishys’ successor as CEO is elected by the Board prior to the Retirement Date, at the request of the Board, Puishys shall resign as Apogee’s CEO and his director position on the Board and from all other director positions he currently holds with Apogee and its affiliates and from all other director positions that he holds with Apogee’s affiliates but shall remain an employee of Apogee until the Retirement Date with such responsibilities reasonably assigned to him by the Board or his successor CEO in connection with the transition of the CEO position to his successor. Assuming that no “Change in Control” as defined in the Change in Control Severance Agreement dated as of January 1, 2018 (the “CIC Severance Agreement”) has occurred prior thereto, effective upon the Retirement Date, the CIC Severance Agreement shall terminate and be of no further force or effect. Additionally, for the avoidance of doubt, if a “Change in Control” as defined in the CIC Severance Agreement occurs prior to the Retirement Date, the CIC Severance Agreement shall govern Puishys’ severance and other post-closing rights and responsibilities in the event of a termination of Puishys’ employment prior to the Retirement Date under circumstances that qualify him for benefits under Section 4 of the CIC Severance

1

Agreement, and Puishys will not be entitled to benefits under this Agreement. Further, for the avoidance of doubt, if a “Change in Control” as defined in the CIC Severance Agreement occurs prior to the Retirement Date and Puishys remains employed through the Retirement Date, then Puishys’ agreement to retire as set forth in the first sentence of this Section 1 and all other provisions of this Agreement shall continue in effect and govern Puishys’ rights and responsibilities in connection with such retirement, and the CIC Severance Agreement shall terminate as of the Retirement Date and be of no further force or effect.

2.    Compensation Until the Retirement Date. Puishys shall continue to receive his current salary and other compensation to which he is entitled in his current position with Apogee to the Retirement Date notwithstanding any earlier resignation from his officer or director positions at the request of the Board in connection with the election of his successor as CEO. On the Retirement Date, all compensation related to Puishys’ employment with Apogee under all other agreements and arrangements, including all perquisite programs, if any, shall cease, and no further compensation shall be due from or paid by Apogee to Puishys, except as contemplated in this Agreement or as otherwise required by law; provided, however, that Apogee shall (i) pay Puishys his monthly base pay through the Retirement Date in accordance with Apogee’s payroll practices, less all applicable withholdings and deductions on the normal payroll date following the Retirement Date, and (ii) reimburse Puishys for unreimbursed business expenses properly incurred to the Retirement Date in compliance with the expense reimbursement policies and procedures of Apogee.

3.    Separation Compensation. After the Retirement Date, and subject to Puishys’ execution, without rescission, of the Release of Claims attached as Exhibit A hereto (the “Release”), Apogee shall make the following payments to and distributions for the benefit of, Puishys, at the time and in the manner set forth below.

(a)    Salary Continuation. Apogee will pay Puishys the equivalent of his current annual rate of salary ($935,000) as follows: (i) on Apogee’s first regular payroll occurring six (6) months after the Retirement Date, Apogee will pay Puishys a lump sum equivalent to six (6) months of his current annual rate of salary; (ii) thereafter, the remaining amount shall be paid in equal installments on Apogee’s regular payroll schedule for a period of six (6) months (both the lump sum and installments to be considered “Salary Continuation Payments”). All applicable payroll tax withholdings and deductions shall be deducted from Puishys’ Salary Continuation Payments.

(b)    Retention Incentive. Apogee will pay Puishys his fiscal 2021 retention incentive to which Puishys would be entitled if employed throughout fiscal year 2021 as CEO based upon the fiscal 2020 rating (90%) in Puishys’ annual CEO performance evaluation as conducted by Apogee’s Board of Directors. The payment of Puishys’ retention incentive will occur on or before March 15, 2021.

(c)    Vesting of Restricted Shares. Effective as of the Retirement Date, the Compensation Committee of the Board (the “Committee”) (i) shall recognize Puishys’ retirement as a “Retirement” for purposes of Puishys’ Restricted Stock Award Agreements with Apogee, dated April 26, 2018, April 25, 2019, and April 23, 2020, thereby causing all 53,628 shares of restricted stock that are unvested pursuant to the terms of such Restricted Stock Award Agreements as of the Retirement Date to immediately vest as of such date, and (ii) shall, pursuant to its authority under Section 3(a)(vi) of the 2009 Omnibus Stock Incentive Plan as Amended and Restated (2011) and Section 3(a)(vi) of the 2019 Stock Incentive Plan as applicable, cause to be accelerated all other unvested (as of such date) shares of restricted stock awarded to Puishys under such Plan and outstanding as of such date.

(d)    Vesting of Non-Qualified Stock Options. Effective as of the Retirement Date, the Committee, pursuant to its authority under Section 3(a)(vi) of the 2019 Stock Incentive Plan, (i) shall recognize Puishys’ retirement as a “Retirement” for purposes of Puishys’ Stock Option Award Agreement with Apogee, dated June 30, 2020, thereby causing all 215,600 non-qualified stock options that are unvested pursuant to the terms of such Stock Option Award Agreement as of the Retirement Date to immediately vest as of such date, and (ii) shall cause to be accelerated all other unvested (as of such date) shares of non-qualified stock options to Puishys under such Plan and outstanding as of such date. Additionally, effective as of the Retirement Date, the Committee, pursuant to its authority under Section 3(a)(vii) of the 2019 Stock Incentive Plan, shall modify such Stock Option Award Agreement to provide that such options may be exercised within six (6) months of the Retirement Date.

(e)    Fiscal 2021 Short-Term Incentive. Apogee will pay Puishys his fiscal 2021 short-term incentive to which Puishys would be entitled if employed as CEO throughout fiscal year 2021. The payment of Puishys’ short-term incentive will occur on or before May 31, 2021, after the Committee determines the amount earned based on Apogee’s achievement of financial performance metrics for the year. The Committee, when exercising its discretion in determining the amount earned based upon Apogee’s financial performance for fiscal 2021, will consider the economic consequences, and the effect on Apogee’s financial performance, of the COVID-19 pandemic that arose after the establishment of the financial performance metrics for the fiscal 2021 short-term incentive plan.

(f)    Medical Coverage. After the Retirement Date, as an additional benefit of Puishys signing this Agreement, Apogee will pay to its vendor its share of the cost of Puishys’ group medical, dental, and vision insurance for eighteen (18) months after the Retirement Date, provided that (i) Puishys pays directly to that vendor his share of the cost of that insurance, and (ii) completes and returns the necessary paperwork to continue that coverage.

3

(g)    Tax Treatment. Apogee and Puishys agree that 100% of the payments and benefits to be provided to Puishys pursuant to this Agreement (including, for the avoidance of doubt, the acceleration of vesting of shares of restricted stock) will be treated as income subject to W-2 reporting and withholdings pursuant to applicable federal, state, and/or local tax laws. Except for such amounts as are withheld from income by Apogee, Puishys agrees that he is solely responsible for any tax obligations resulting from the payments to be made to him pursuant to this Agreement. Apogee makes no representations or warranties with respect to the tax consequences of the payments referenced in this Agreement. Puishys further acknowledges and agrees that the payments set forth herein may result in taxable income to Puishys under applicable federal, state, and/or local tax laws. Puishys acknowledges and agrees that he will not seek any indemnification from Apogee with respect thereto.

4.    Continued Executive Benefits.

(a)    Prior to Retirement Date. Until the Retirement Date, Puishys shall be entitled to such medical, dental, disability, life insurance coverage, vacation, sick leave, holiday benefits and any other benefits, in each case as are customarily made available to Apogee’s executive officers, all in accordance with Apogee’s benefits program in effect from time to time.

(b)    After Retirement Date. After the Retirement Date, Puishys shall be entitled only to the benefits set forth in Section 3 of this Agreement, and to benefits mandated by applicable Minnesota law, including, without limitation, the right to continue, at Puishys’ expense, to participate in Apogee’s group life insurance program for the legally required period following his Retirement Date. For the avoidance of doubt, the parties acknowledge and agree that Puishys shall not continue to participate, after the Retirement Date, in any of the following plans, in each case, as amended to date, except with respect to balances of deferred accounts existing in any such plan as of the Retirement Date: (i) Apogee Enterprises, Inc. Amended and Restated Employee Stock Purchase Plan, (ii) Apogee Enterprises, Inc. Deferred Incentive Compensation Plan (2011), (iii) Apogee Enterprises, Inc. 401(k) Retirement Plan, and (iv) any executive perquisite plan of Apogee.

(c)    Death or Disability. In the event that Puishys dies or becomes disabled on or after the Retirement Date, but before all payments under Sections 2 or 3 have been made, his heirs, administrators, representatives, executors or his estate shall be entitled to the remaining compensation and benefits due to Puishys under those sections; provided that, if Puishys had not already entered into the Release prior to his death or disability, in order to receive the payments and benefits due to Puishys under Section 3, an authorized representative must enter into the Release on behalf of such heirs, administrators, representatives, executors or estate.

5.    Release. In consideration of the promises, covenants and other valuable consideration provided by Apogee in this Agreement, Puishys agrees that in order to be entitled to receive the payments and other benefits described in Section 3 of this Agreement, he must execute the Release attached hereto as Exhibit A on or within 21 days following the Retirement Date. Puishys specifically agrees and acknowledges: (a) that his agreement to waive rights under the Release is knowing and voluntary as required under the Age Discrimination in Employment Act (“ADEA”) and the Older Workers Benefit Protection Act (“OWBPA”); (b) that he understands the terms of the Release; (c) that Apogee advises Puishys to consult with an attorney prior to executing the Release; (d) that Apogee has given him a period of up to twenty- one (21) days within which to consider the Release; (e) that nothing in this Agreement or the Release prevents or precludes Puishys from challenging or seeking a determination in good faith of the validity of the Release under the ADEA, nor impose any condition precedent, penalties or costs for doing so, unless specifically authorized by federal law; and (f) that, following his execution of the Release, he has fifteen (15) days in which to rescind the Release, and that, if he chooses not to so rescind, the Release shall then become effective and enforceable. Puishys represents that if he signs the Release before the expiration of the 21-day review period, it is because Puishys does not need any additional time to decide whether to sign the Release. Changes to this Agreement, whether material or immaterial, will not restart the 21-day period. The Release shall be subject to the exceptions set forth in the last sentence of Section 1 thereof.

6.    Confidential Information. Puishys will not make any unauthorized use, publication or disclosure, either prior to, on or after the Retirement Date, of any confidential, secret or proprietary documents, materials or other information of or regarding Apogee, its affiliates or any of their respective existing businesses generated or acquired by him during his employment with Apogee, including, but not limited to, information of a confidential or trade secret nature (“Confidential Information”). Confidential Information includes information not generally known by or available to the public about or belonging to Apogee or belonging to other persons to whom Puishys knows, or has reason to know, that Apogee may have an obligation to maintain information in confidence including, without limitation, all strategic plans and all financial, operational and other forecasts for Apogee or any of its affiliates. Authorization for disclosure of Confidential Information, which may be withheld at Apogee’s sole discretion, may be obtained only from Apogee’s General Counsel or designee. Puishys will not disclose to Apogee, or induce Apogee to use, any confidential or trade secret information or material belonging to others. Notwithstanding anything in this Section to the contrary, nothing in this Agreement shall be deemed to prevent Puishys from providing information about Apogee to, or otherwise participating in any investigation or proceeding conducted by, the U.S. Equal Opportunity Employment Commission, U.S. National Labor Relations Board, the U.S. Occupational Health and Safety Administration, U.S. Securities and Exchange Commission or any other comparable state or local agency nor from disclosing Confidential Information as may be required by

5

applicable law or regulation, or pursuant to the valid order or subpoena of a court of competent jurisdiction or an authorized governmental agency, provided that the disclosure does not exceed the extent of disclosure required by such law, regulation, order or subpoena.

7.    Non-Competition.

a.    As a material inducement for Apogee to enter into this Agreement, Puishys agrees to protect Apogee’s Confidential Information and business goodwill and to not to compete with Apogee during the period prior to the Retirement Date and in accordance with the terms and for the additional periods set forth below:

6

b.    The parties intend that each of the covenants referenced in Sections 6 and 7 shall be construed as a series of separate covenants, one for each state of the United States and each county of each state of the United States. If, in any judicial proceeding, a court shall refuse to enforce any of the separate covenants (or any part thereof) deemed included in such clauses, then such unenforceable covenant (or such part) shall be deemed eliminated from this Agreement for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced. In the event that the provisions of this Section 7 should ever be deemed to exceed the time or geographic limitations, or the scope of this covenant, permitted by applicable law, then such provisions shall be reformed to the maximum time or geographic limitations, as the case may be, permitted by applicable laws. The unenforceability of any covenant in Sections 6 or 7 shall not preclude the enforcement of any other of said covenants or provisions or of any other obligation of Puishys or Apogee hereunder, and the existence of any claim or cause of action of Puishys or Apogee against the other, whether predicated on the Agreement or otherwise, shall not constitute a defense to the enforcement by Apogee of any of said covenants.

c.    Puishys understands and agrees that damages may be an inadequate remedy in the event of a breach or intended or threatened breach by him of any of his obligations in Sections 6 or 7, and that any such breach may cause Apogee irreparable injury and damage. Accordingly, Puishys agrees that Apogee shall be entitled, without waiving any additional rights or remedies otherwise available to Apogee and without the necessity of proving the inadequacy of damages or of posting any bond, to injunctive and other such equitable relief in the event of a breach or intended or threatened breach of any of said covenants by Puishys.

8.    Return of Property. On or before the Retirement Date, Puishys shall return all equipment and property in his possession that belongs to Apogee, including all files and programs stored electronically or otherwise that relate or refer to Apogee, and all original and copies of documents, notes, memoranda or any other written materials that relate or refer to Apogee, including material that constitutes Confidential Information, other than information or documents relating to Puishys’ Apogee compensation or benefit plans or programs in which he participates or participated.

9.    Non-Disparagement.

a.    Puishys agrees that he will not, and will use his reasonable efforts not to allow anyone acting on his behalf or at his direction at any time to, criticize, defame or disparage Apogee, its affiliates, any of their directors, officers or employees, any of their plans, or their actions to any third party, either orally or in writing. The

7

provisions of this Section 9(a) shall not apply to any truthful statement(s) required to be made by Puishys or by any representative of Puishys in any legal proceeding or governmental (including all agencies thereof) or regulatory filing, investigation or proceeding.

b.    Apogee agrees that none of its Senior Executives (as defined below) will criticize, defame or disparage Puishys, his performance with Apogee, his plans, or his actions to any third party, either orally or in writing. The provisions of this Section 9(b) shall not apply to any truthful statement(s) required to be made by Apogee or by any representative of Apogee in any legal proceeding or governmental (including all agencies thereof) or regulatory filing, investigation or proceeding. For purposes of this Section 9(b), the term “Senior Executives” shall mean each of Apogee’s directors and its Chief Executive Officer, Chief Financial Officer, Vice President and General Counsel, Chief Human Resources Officer, and Vice President and Treasurer.

10.    Apogee’s Default in Payment. Should Apogee default in timely payment on the due date of any payment or amount due under this Agreement, Puishys shall give written notice of such default to the person specified in or pursuant to this Agreement to receive notice on behalf of Apogee. Apogee shall have ten (10) calendar days after the receipt of such a notice of default to cure any payment default. Puishys’ failure to provide such notice shall not negate Apogee’s obligation to make payment of any amounts due to Puishys under this Agreement, but Apogee’s ten-calendar-day cure period shall not commence until it receives such notice from Puishys.

11.    Breach of this Agreement. If a court of competent jurisdiction determines that either party has breached or failed to perform any part of this Agreement, the parties agree that the non-breaching party shall be entitled to injunctive relief to enforce this Agreement and that the breaching party shall be responsible for paying the non-breaching party’s costs and attorneys’ fees incurred in enforcing this Agreement.

12.    Severability. If any provision of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions shall nevertheless continue in full force and effect.

13.    Ambiguities in this Agreement. The parties acknowledge that this Agreement has been drafted, prepared, negotiated and agreed to jointly, with advice of each party’s respective counsel, and to the extent that any ambiguity should appear, now or at any time in the future, latent or apparent, such ambiguity shall not be resolved or construed against either party.

For the avoidance of doubt, each payment made hereunder, whether or not part of a series of payments, will be treated as a separate payment for purposes of application of Section 409A. Neither Apogee nor any of its officers, directors, agents or affiliates shall be obligated, directly or indirectly, to Puishys or any other person for any taxes, penalties, interest or like amounts that may be imposed on Puishys or other person due to any failure to comply with Section 409A.

FOR RELEASE:    September 17, 2020

Apogee Enterprises Announces Planned Retirement of CEO Joe Puishys at the End of the Fiscal Year

MINNEAPOLIS, MN, September 17, 2020 – Apogee Enterprises, Inc. (Nasdaq: APOG) today announced that Joseph F. Puishys has communicated to the Board his intent to retire from his role as Chief Executive Officer and member of the company’s Board of Directors effective February 27, 2021, the conclusion of the company’s fiscal year. Joe has served as CEO and a member of the company’s Board since 2011. The Board has initiated a process to identify the company’s next CEO and has retained a leading executive search firm to support the process.

“On behalf of the Board, I want to thank Joe for his many years of dedicated leadership,” said Donald A. Nolan, Chair of the Apogee Board. “During his tenure, Joe guided a transformation of Apogee, building a stronger, more diversified business that achieved considerable growth and improved profitability. Most importantly, his contributions leave the company with significantly improved growth potential. I would particularly like to recognize his efforts over the past six months, ensuring the safety and health of Apogee employees during the COVID pandemic while continuing to serve our customers and maintaining the long-term health of the business. Joe will clearly leave behind a company that is well positioned for continued success.”

“I’d like to thank all of Apogee’s employees for their support and partnership over the past nine years. It has truly been an honor to lead Apogee’s team and I am proud of what we’ve accomplished,” Puishys said. “The timing for my retirement is right for me and the company. We have built a leadership team at Apogee with a balance of experienced industry executives along with new leaders who bring fresh eyes to our future. We’ve recently launched new productivity initiatives to complement the growth strategies in our segments. And we’ve navigated the economic and personal challenges of COVID in a manner that leaves me proud of our business performance and proud of how we treated our people. It is the right time and I look forward to working with the Board to ensure a smooth transition.”
