Mercury Systems EVP Stuart Kupinsky sells $86,520 in shares

Mercury Systems Inc. (MRCY) Executive Vice President and Chief Legal Officer, Stuart Kupinsky, sold 1,000 shares of the company's common stock on September 21, 2026. The sale, conducted under a pre-approved Rule 10b5-1 trading plan, generated $86,520 based on a per-share price of $86.52. This transaction occurred despite the stock's 52-week high of $128.45 and a current price of $82.72, indicating the company is perceived as overvalued relative to its fair value.

Mercury Systems reported a loss of $0.50 per share in the past year, but analysts anticipate profitability by fiscal 2027 with projected earnings of $1.71 per share. Kupinsky still holds 60,971 shares directly and indirectly owns 1,281 shares via a 401K plan. Mercury Systems' fiscal fourth-quarter 2026 results showed a record revenue of $289.8 million, exceeding market expectations.

However, adjusted earnings per share of $0.37 fell short of the estimated $0.38. The company's fourth-quarter bookings grew by 93.1%, reaching $1.945 billion, a 38.4% increase from the prior year. This growth led to RBC Capital raising its price target to $120 with an Outperform rating, and Piper Sandler increasing it to $131, also maintaining an Overweight rating.

Guggenheim Securities initiated coverage with a buy rating and a price target of $115, while Baird reiterated an Outperform rating with a $130 target. These reactions reflect analysts' cautious optimism about Mercury Systems' strategic outlook and potential growth driven by global defense modernization trends.
