This Cooperation Agreement, dated as of November 10, 2019 (this “Agreement”), is by and among Apogee Enterprises, Inc.
(the “Company”) and the persons and entities set forth on Schedule A hereto (collectively, and, for clarity and as applicable, each member thereof acting individually, the “Engaged Group”). 

RECITALS 
 WHEREAS, the
Company and Engaged Capital, LLC, a member of the Engaged Group, have engaged in various discussions and communications concerning the Company’s business, financial performance and strategic plans; 

WHEREAS, as of the date hereof, the Engaged Group is the Beneficial Owner (as defined below) of 1,689,332 shares of common stock, $0.33 1/3
par value per share, of the Company (the “Common Stock”), or approximately 6.4% of the Common Stock issued and outstanding on the date hereof; and 

WHEREAS, the Company and the Engaged Group have determined to come to an agreement with respect to certain matters relating to the composition
of the Board of Directors of the Company (the “Board”) and certain other matters, as provided in this Agreement; 

AGREEMENT 
 NOW,
THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties (as defined
below), intending to be legally bound hereby, agree as follows: 
 Section 1. Board Appointments, Committees and Related
Agreements. 
 (a) Board Matters. 

(i) Following the execution of this Agreement, the Board and all applicable committees of the Board shall take all necessary actions to
nominate Christina M. Alvord, Frank G. Heard and Elizabeth M. Lilly (each individually, a “New Director” and together, the “New Directors”) for election to the Board as Class III directors at the 2019 annual meeting
of shareholders of the Company (the “2019 Annual Meeting”). The Company shall recommend, support and solicit proxies for the election of the New Directors at the 2019 Annual Meeting in the same manner as for the Company’s other
nominee(s) to the Board at the 2019 Annual Meeting. The Company shall nominate the following four directors for election to the Board at the 2019 Annual Meeting: each New Director and Mark A. Pompa. 

(ii) The Board shall not change the classification of any incumbent director of the Board prior to the 2019 Annual Meeting. 

(iii) For so long as the Engaged Group continuously beneficially owns in the aggregate at least the lesser of (A) 3.5% of the
Company’s then outstanding Voting Securities (as defined below) and (B) 929,410 shares of Common Stock (subject to adjustment 












 
for stock splits, reclassifications and combinations, the “Ownership Minimum”), the Company agrees that after the conclusion of the 2019 Annual Meeting and prior to the
Termination Date (as defined below), the size of the Board shall not exceed ten members unless at least two-thirds of the directors then serving on the Board, including two New Directors, approve such increase. 

(b) Replacements. From the date of this Agreement until the Termination Date, if any New Director is no longer able to serve as a
director for any reason unforeseen by the Engaged Group as of the date of this Agreement and so long as the Engaged Group continuously beneficially owns in the aggregate at least the Ownership Minimum, then the Engaged Group and the Company shall
work together to identify a mutually-acceptable replacement director who satisfies the Director Criteria (as defined below) to fill the resulting vacancy and any such person shall be subject to review and approval by the Nominating and Corporate
Governance Committee and the Board as well as the Engaged Group (any such replacement director, a “Replacement Director”). Upon a Replacement Director’s appointment to the Board, the Board and all applicable committees of the
Board shall consider whether such Replacement Director has the necessary qualifications to be appointed to any committee of the Board of which the replaced director was a member immediately prior to such director’s departure from the Board,
and, if the qualifications for such committee(s) are met, shall appoint such Replacement Director to such committee(s) or, if the qualifications for such committee(s) are not met, shall consider in good faith appointing the Replacement Director to
other committees of the Board. Any Replacement Director designated pursuant to this Section 1(b) replacing a New Director prior to the 2019 Annual Meeting shall stand for election at the 2019 Annual Meeting together with the
Company’s other nominees. Upon a Replacement Director’s appointment to the Board, such Replacement Director shall be deemed to be a New Director for all purposes under this Agreement. 

(c) Director Committee Appointments. Subject to the Company’s Corporate Governance Guidelines, the listing rules of the NASDAQ
Global Select Market and applicable law, the Board shall take all actions necessary to ensure that from and after, and contingent upon, the election of the New Directors to the Board, (i) Ms. Alvord is appointed to the Nominating and
Corporate Governance Committee of the Board, (ii) Mr. Heard is appointed to the Audit Committee of the Board and (iii) Ms. Lilly is appointed to the Compensation Committee of the Board, along with such other Board committees, if
any, to be determined by the Board in its sole discretion. Without limiting the foregoing, the Board shall give each of the New Directors the same due consideration for membership to any committee of the Board as it would any other independent
director. 
 (d) Additional Agreements. 

(i) The Company intends to hold the 2019 Annual Meeting on or prior to January 15, 2020. The Company shall use commercially reasonable
efforts to hold the 2019 Annual Meeting as soon as reasonably practicable after the date on which the SEC (as defined below) has indicated to the Company that the Company may file its definitive proxy statement for the 2019 Annual Meeting. 

(ii) The Engaged Group agrees (A) to cause its Affiliates and Associates (each as defined below) to comply with the terms of this
Agreement and (B) that it shall be responsible for any breach of this Agreement by any such Affiliate or Associate. A 

  
 2 













 
breach of this Agreement by an Affiliate or Associate of any member of the Engaged Group, if such Affiliate or Associate is not a Party, shall be deemed to occur if such Affiliate or Associate
engages in conduct that would constitute a breach of this Agreement if such Affiliate or Associate were a Party to the same extent as the Engaged Group. 

(iii) Until the Termination Date, the Engaged Group agrees that it shall, and shall cause each of its Affiliates and Associates to, appear in
person or by proxy at each annual or special meeting of the shareholders of the Company, or any action by written consent of the Company’s shareholders in lieu thereof, and any adjournment, postponement, rescheduling or continuation thereof
(each, a “Shareholder Meeting”) and vote all Voting Securities beneficially owned, directly or indirectly, by the Engaged Group or any Affiliate thereof (or which the Engaged Group or such Affiliate or Associate has the right or
ability to vote) at such meeting (A) in favor of the nominees for director recommended by the Board, against the election of any nominee for director not approved, recommended and nominated by the Board for election at any such meeting, and
against any removal of any director of the Board; and (B) in accordance with the Board’s recommendation with respect to any other matter presented at such meeting; provided, however, that if Institutional Shareholder Services Inc.
(“ISS”) recommends otherwise with respect to any matter under clause (B) of this Section 1(d)(iii), the Engaged Group shall be permitted to vote in accordance with ISS’s recommendation; provided,
further, that the Engaged Group shall be permitted to vote in its sole discretion with respect to any publicly announced proposals relating to an Extraordinary Transaction. 

(iv) Until the Termination Date, upon written request from the Company, the Engaged Group shall promptly provide the Company with information
regarding the amount of the securities of the Company then beneficially owned by the Engaged Group. Such information provided to the Company shall be kept strictly confidential unless required to be disclosed pursuant to law, the rules of any stock
exchange or any Legal Requirement (as defined below). 
 Section 2. Standstill Agreement. Until the Termination Date, the
Engaged Group shall not, and shall cause each of its Affiliates and Associates not to, directly or indirectly, in any manner, alone or in concert with others: 

(a)    (i) acquire, cause to be acquired, or offer, seek or agree to acquire, whether by purchase, tender or exchange
offer, through the acquisition of control of another person, by joining or forming a partnership, limited partnership, syndicate or other group (including any group of persons that would be treated as a single “person” under
Section 13(d) of the Exchange Act (as defined below)), through swap or hedging transactions or otherwise (the taking of any such action, an “Acquisition”), Beneficial Ownership of any securities or assets of the Company (or any
direct or indirect rights or options to acquire such ownership, including voting rights decoupled from the underlying Voting Securities) such that after giving effect to any such Acquisition, the Engaged Group or any of its Affiliates and Associates
holds, directly or indirectly, in excess of 9.9% of the Voting Securities, (ii) acquire, cause to be acquired or offer, seek or agree to acquire, whether by purchase or otherwise, any interest in any indebtedness of the Company or

case other than securities of the Company;

 (c) solicit any proxy,
consent or other authority to vote of shareholders or conduct any other referendum (binding or non-binding) (including any “withhold,” “vote no” or similar campaign) with respect to, or from the holders of, Voting Securities, or
become a “participant” (as such term is defined in Instruction 3 to Item 4 of Schedule 14A promulgated under the Exchange Act) in, or knowingly assist, advise, initiate, encourage or influence any person (other than the Company) in,
any “solicitation” (as such term is defined in Rule 14a-1 promulgated under the Exchange Act) of any proxy, consent or other authority to vote any Voting Securities (other than such assistance, advice, encouragement or influence that is
consistent with the Board’s recommendation in connection with such matter); 
 (d)    (i) grant any proxy, consent
or other authority to vote with respect to any matters (other than to the named proxies included in the Company’s proxy card for any Shareholder Meeting or as otherwise permitted by Section 1(d)(iii)) or (ii) deposit or agree
or propose to deposit any securities of the Company in any voting trust or similar arrangement, or subject any securities of the Company to any agreement or arrangement with respect to the voting of such securities (including a voting agreement or

the Company or (B) customary brokerage accounts, margin accounts and prime brokerage accounts; 
 (e) knowingly encourage, advise or
influence any person or knowingly assist any person in so encouraging, advising or influencing any person, with respect to the giving or withholding of any proxy, consent or authority to vote any Voting Securities or in conducting any referendum
(binding or non-binding) (including any “withhold,” “vote no,” or similar campaign); 
 (f) without the prior written
approval of the Board, separately or in conjunction with any other person in which it is or proposes to be either a principal, partner or financing source or is acting or proposes to act as broker or agent for compensation, propose, suggest or
recommend publicly or in a manner that the Engaged Group is required under applicable law, rule or regulation to disclose publicly or participate in, effect or seek to effect, any Extraordinary Transaction or knowingly encourage any other third
party in any such activity; provided, however, that nothing in this Section 2 shall be interpreted to prohibit the Engaged Group from proposing, suggesting or recommending any Extraordinary Transaction privately to


  
 4 













 
the Company so long as any such action is not publicly disclosed by the Engaged Group and is made by the Engaged Group in a manner that would not reasonably be expected to require the public
disclosure thereof by the Company, the Engaged Group or any other person; 
 (g) form, join, encourage the formation of, or in any way
participate in any partnership, limited partnership, syndicate or group (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any Voting Securities (other than a group that includes all or some of the members of the
Engaged Group, but does not include any other entities or persons that are not members of the Engaged Group as of the date hereof; provided that nothing herein shall limit the ability of an Affiliate of the Engaged Group to join such group
following the execution of this Agreement, so long as any such Affiliate agrees to be bound by the terms and conditions of this Agreement); 

(h) make or publicly advance any request or proposal to amend, modify or waive any provision of this Agreement, or take any action challenging
the validity or enforceability of any provision of or obligation arising under this Agreement; provided that the Engaged Group may make confidential requests to the Board to amend, modify or waive any provision of this Agreement, which the
Board may accept or reject in its sole and absolute discretion, so long as any such request is not publicly disclosed by the Engaged Group and is made by the Engaged Group in a manner that would not reasonably be expected to require the public
disclosure thereof by the Company, the Engaged Group or any other person; 
 (i) make a request for a list of the Company’s
shareholders or for any books and records of the Company pursuant to Section 302A.461 of the Minnesota Business Corporation Act; or

Agreement) or encourage, assist, solicit, seek, or seek to cause any person to undertake any action inconsistent with this Section 2. 

Notwithstanding anything in this Agreement to the contrary, the foregoing provisions of this Section 2 shall not be deemed to restrict the Engaged
Group from: (i) communicating privately with the Board or any of the Company’s officers regarding any matter, so long as such communications are not intended to, and would not reasonably be expected to, require any public disclosure of
such communications, (ii) communicating privately with shareholders of the Company and others in a manner that does not otherwise violate this Section 2 or Section 5, or (iii) making any public disclosure necessary
to comply with any Legal Requirement. Furthermore, for the avoidance of doubt, nothing in this Agreement shall be deemed to restrict in any way the New Directors in the exercise of their fiduciary duties under applicable law as directors of the

counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or any action of the Company or the Engaged Group in the negotiation, administration, performance or enforcement hereof shall be governed by
and construed and enforced in accordance with the laws of the State of Minnesota without giving effect to any choice or conflict of laws provision or rule (whether of the State of Minnesota or any other jurisdiction) that would cause the application
of the laws of any jurisdiction other than the State of Minnesota. Each Party irrevocably agrees that any legal action or proceeding with respect to this Agreement and any rights and obligations arising hereunder, or for recognition and enforcement
