Mercury Systems (MRCY) CFO David Farnsworth Forfeits 16,275 Shares

What Happened
David E. Farnsworth, Executive VP and CFO of Mercury Systems (MRCY), had 16,275 shares disposed to the issuer on Aug 14, 2026. The Form 4 reports the disposition as $0.00 in proceeds — these were performance stock awards forfeited for below-target performance (see footnote F1), not an open-market sale.

Context
This was a forfeiture of unvested/performance-based awards, not a sale by the insider — it reflects the awards failing to meet performance conditions rather than the CFO cashing out. For retail investors, forfeitures reduce potential future dilution but do not indicate insider buying or selling intent.
