Mercury Systems, Inc. MRCY
Starboard, a 7.33% owner of Mercury Systems, demands the board scrap the December 2021 poison pill or raise its 7.5% trigger to 15% and put it to a shareholder vote.
Thesis
Starboard Value, which discloses a 7.33% stake in Mercury Systems, objects to the shareholder rights plan the board adopted on December 27, 2021 — arguing it is not in the best interests of shareholders. Signed by Managing Member Jeffrey C. Smith, the letter frames the poison pill as an entrenchment tool: its 7.5% trigger (10% for passive investors) sits abnormally low and effectively caps Starboard's ability to continue building a position and engaging management. Starboard asks the board to eliminate the Rights Plan outright, or at minimum raise the trigger to 15% for all shareholders and put the plan to a binding shareholder vote. The tone is collaborative in language — referencing months of dialogue and a 'bright future' — but adversarial in substance, signaling a live governance fight on top of Starboard's ongoing value-creation engagement.
SCQA
Starboard Value owns 7.33% of Mercury Systems and has been engaging with management for several months on what it believes is a substantial value-creation opportunity.
On December 27, 2021 the Mercury board adopted a shareholder rights plan with an unusually low 7.5% trigger (10% for passive holders) — functionally a poison pill that caps Starboard's stake and chills further engagement.
Eliminate the Rights Plan immediately, or at minimum raise the trigger to 15% for all shareholders and submit the plan to a binding shareholder vote.
Removing or loosening the pill restores proper governance and preserves Starboard's ability to keep accumulating and pressing the board to unlock the substantial value it sees at Mercury.
The three reasons
- 1
Rights Plan is not in the best interests of Mercury Systems shareholders
- 2
Low 7.5% trigger entrenches the board and chills legitimate shareholder engagement
- 3
Shareholders, not the board alone, should decide whether a poison pill stays in place
Primary demands
- Immediately eliminate the shareholder rights plan (poison pill) adopted on December 27, 2021
- Alternatively, raise the Rights Plan ownership trigger from 7.5% (10% passive) to 15% for all shareholders
- Put the Rights Plan to a vote of all shareholders

Notes
One-page open letter from Jeffrey C. Smith to the Mercury Systems Board demanding elimination or material loosening of a poison pill adopted Dec 27, 2021 at a 7.5% trigger (10% passive). Tone is collaborative in language ('appreciate the conversations', 'bright future') but adversarial in substance — Starboard at 7.33% is effectively right at the trigger, so the pill functionally caps their stake. No financial thesis, valuation, KPIs beyond ownership thresholds, or peer benchmarking — pure governance/anti-entrenchment ask. Classified as follow_up because the letter references prior engagement ('over the past several months') and is part of Starboard's ongoing MRCY campaign rather than the initial thesis debut. thesis_types includes activist_defense since the letter primarily defends Starboard's ability to accumulate/engage against a defensive pill.
