What this transaction means for investors

Lance’s late February sale of aerospace and defense technology company Mercury Systems capitalized on the recent strong performance of both the stock and its sector. As of March 24, the stock is still up 68% year over year on a total return basis, though it’s down slightly from its more than 100% return earlier this year.

The company announced its results for the second quarter of fiscal year 2026 (ended Dec. 26, 2025) on Feb. 3. Q2 bookings were up 18.6% year over year and the company celebrated a record backlog of $1.5 billion, an 8% year-over-year increase. First-half revenue of $233 million was also a record.

In March, the company completed its acquisition of SolderMask Inc., a provider of specialized manufacturing processes that were already in use across more than 20 Mercury Systems programs. Bringing the processes in-house should allow Mercury Systems to expand manufacturing capacity and improve production rate.

Mercury Systems currently trades at a price-to-sales (P/S) ratio of 4.98, which is close to the aerospace and defense industry average P/S of 4.57, and below the peer group average of 11.29, according to Simply Wall St. While some still believe the stock is overvalued, bulls may be interested in the company’s strategic acquisitions and growing backlog amid enhanced recent interest in the aerospace and defense sector.
