Item 1.01 Entry Into a Material Definitive Agreement.
On June 23, 2022, Mercury Systems, Inc. (the “Company”) entered into agreements with each of JANA Partners LLC (“JANA”) and Starboard Value LP and certain of its affiliates (collectively, “Starboard”), with the cooperation agreement with JANA referred to herein as the “JANA Agreement” and the agreement with Starboard referred to herein as the “Starboard Agreement”, and together with the JANA Agreement, the “Agreements”.
Pursuant to the Agreements, the Company has appointed William L. Ballhaus (the “JANA Nominee”) and Howard L. Lance (the “Starboard Nominee”) as independent directors in Class I of the Board of Directors (the “Board”) for a term expiring at the Company’s 2022 annual meeting of stockholders (the “2022 Annual Meeting”) and has agreed to re-nominate such directors for a three-year term at the 2022 Annual Meeting. Per the Agreements, Messrs. Ballhaus and Lance have each been appointed to the Nominating and Governance Committee and the M&A and Finance Committee and Mr. Lance has been appointed to the Human Capital and Compensation Committee. The Company also appointed Mr. Ballhaus to the Audit Committee and Mr. Lance to the Government Relations Committee. The Company agreed to use its reasonable best efforts to schedule and hold the 2022 Annual Meeting no later than November 15, 2022. During the terms of their respective agreements, and subject to the conditions therein, JANA and Starboard are entitled to designate a replacement director that is reasonably acceptable to the Board if the shareholder’s designated director is unable or unwilling to serve or resigns or is removed as a director. To enable the election of Messrs. Ballhaus and Lance, the Board has temporarily expanded the size of the Board from 9 to 11 directors. Following the Company’s 2022 Annual Meeting until the end of the Standstill Period (as defined below), the number of directors of the Company constituting the Board shall not exceed 9 directors.
JANA agreed to certain customary standstill provisions during the “Cooperation Period”, which continues until the date that is the earlier of (i) 30 days prior to the expiration of the Company’s advance notice period for the nomination of directors at the Company’s 2023 annual meeting of stockholders and (ii) the date that is 145 days prior to the first anniversary of the 2022 Annual Meeting.
Pursuant to the JANA Agreement, with respect to the 2022 Annual Meeting and any special meeting during the Cooperation Period, JANA agreed to vote (A) in favor of all nominees for director nominated by the Board, (B) in favor of the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm, (C) solely with respect to the 2022 Annual Meeting, in favor of the Board’s recommendation with respect to any amendment to the Company’s stock incentive plan to replenish shares available for grants under that plan in an amount not to exceed 2,000,000 shares, and (D) in accordance with the Board’s recommendations with respect to any other proposal or business that may be the subject of stockholder action at the 2022 Annual Meeting; provided, however, that in the event that Institutional Shareholder Services (“ISS”) or Glass Lewis & Co. LLC (“Glass Lewis”) recommends otherwise with respect to any Company or stockholder proposal (other than the proposal set forth in (A)), JANA is permitted to vote in accordance with the ISS or Glass Lewis recommendation. During the Cooperation Period, JANA may vote its shares in its discretion with respect to any proposal to authorize or approve specified extraordinary transactions or the Company’s “say-on-pay” proposal.
Starboard agreed to certain customary standstill provisions during the “Standstill Period”, which continues until the earlier of (i) the date that is 30 days prior to the deadline for the submission of stockholder nominations for the Company’s 2023 annual meeting of stockholders and (ii) the date that is 145 days prior to the first anniversary of the 2022 Annual Meeting.

Pursuant to the Starboard Agreement, with respect to the 2022 Annual Meeting, Starboard agreed to vote (A) in favor of all nominees for director nominated by the Board, (B) in accordance with the Board’s recommendation with respect to the Company’s stock incentive plan to replenish shares available for grants under that plan in an amount not to exceed 2,000,000 shares, (C) in favor of the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm, and (D) in accordance with the Board’s recommendation with respect to any other Company proposal or stockholder proposal presented at the 2022 Annual Meeting, other than with respect to the Company’s “say-on-pay” proposal, which Starboard is permitted to vote as it sees fit; provided, however, that in the event that ISS or Glass Lewis recommends otherwise with respect to any Company or stockholder proposal (other than proposals relating to the election or removal of directors), Starboard is permitted to vote in accordance with the ISS or Glass Lewis recommendation. During the Standstill Period, Starboard is permitted to vote in its discretion on any proposal of the Company with respect to any extraordinary transaction.
The Company agreed to reimburse the reasonable, documented out-of-pocket fees and expenses (including legal expenses) incurred by JANA and Starboard through the date of their respective agreements, including, but not limited to, their Schedule 13D filings and the negotiation and execution of their respective agreement, provided that such reimbursement does not exceed a cap set forth in the applicable agreement.
Pursuant to the Agreements, on June 23, 2022, the Company amended the Rights Agreement, dated as of December 27, 2021, to increase the ownership threshold for a person to be an “Acquiring Person” (as defined in the Rights Agreement) from 7.5% of common stock to 10% of common stock (10% of common stock to 20% of common stock in the case of a passive institutional investor). The Rights Agreement, as amended, will expire no later than upon conclusion of the 2022 Annual Meeting.
The Company and each of JANA and Starboard made certain customary representations, agreed to mutual non-disparagement provisions, and agreed to jointly issue a press release announcing certain terms of the Agreements.
The foregoing description does not purport to be complete and is qualified in its entirety by reference to the JANA Agreement and the Starboard Agreement, copies of which are attached hereto as exhibits 10.1 and 10.2 respectively, and which are incorporated herein by reference.

Pursuant to the policy, new non-employee directors are granted equity awards in connection with their first election to the Board. This award consists of shares of restricted stock with a value equal to $225,000 divided by the average closing price of the Company’s common stock during the 30 calendar days prior to the date of grant.
