Shares of Ocean Power Technologies surged 10.2% to $2.33 after the company announced its unmanned surface vessels completed five military mission sets at REPMUS 2026, a NATO-linked naval exercise off Portugal. The pop extends a volatile week for a company trying to convince Wall Street that its defense ambitions are real — despite burning cash faster than it earns revenue.
The Drones Did Real Work, Not Just a Demo
OPT's vessels were the only U.S. unmanned surface vessels to integrate directly with U.S. command and control during the exercise.
The company's three drone classes handled five distinct jobs: seafloor mapping ahead of amphibious landings, mine detection near harbors, harbor security, surveillance and reconnaissance, and surface target identification. COO Jason Weed framed it bluntly: "our vessels weren't on display; they were given work." For investors, the distinction matters — operational integration with allied command systems is a prerequisite for winning actual procurement contracts.
Defense Buzz Is Growing, but Revenue Remains Tiny
Revenue for Q1 fiscal 2027 was $1.7 million, up 44% year over year. That sounds healthy until you see the other side: cost of revenues surged to $4.5 million, producing a gross loss of $2.8 million and an operating loss of $15.1 million.
Backlog rose 58% to $19.1 million , and OPT was recently named one of six potential awardees on a $40 million Navy ocean-mapping contract running through July 2028. The pipeline is expanding, but losses still dwarf sales by a wide margin.
Cash Runway Is the Real Risk
Cash, equivalents, and short-term investments totaled just $7.4 million, with $10.2 million burned in operations during the quarter alone.
The company executed a 1-for-30 reverse stock split effective September 14 — a move typically used to avoid exchange delisting. As of September 1, OPTT had roughly 270 million pre-split shares outstanding , now compressed to about 9.1 million. Outstanding convertible notes bearing 4.5% interest mature October 2027 , adding further dilution risk.
The Bottom Line for Shareholders REPMUS validates that OPT's technology works inside military operations, not just at trade shows. But validation and revenue are different things. With a sub-$25 million market cap, a cash pile that won't last two quarters at current burn rates, and a freshly reverse-split share count, OPTT remains a high-risk bet that defense contracts will arrive before the balance sheet runs dry.
