New York, Jan 8, 2026, 12:43 ET — Regular session
- Karman Holdings shares rose about 10% after it agreed to buy Seemann Composites and Materials Sciences.
- The $220 million deal is mostly cash, with a small stock component, and is expected to close in fiscal Q1 2026.
- Management set a Jan. 21 investor call to discuss the transaction and a higher fiscal 2026 outlook.
Karman Holdings Inc shares were up $9.63, or 10.5%, at $101.35 in midday New York Stock Exchange trading, after the space-and-defense supplier unveiled an acquisition that would take it deeper into U.S. Navy work.
The company agreed to buy Seemann Composites LLC and Materials Sciences LLC for $210 million in cash and about $10 million in Karman stock, subject to customary adjustments, a filing showed.
Karman told investors the purchase should be “immediately accretive” in 2026 — shorthand for lifting profit measures such as earnings per share — and said it plans to raise its fiscal 2026 outlook. “Entering the strategic maritime defense market … has been on our strategic roadmap for years,” CEO Tony Koblinski said.

Seemann and MSC make composite systems used across undersea and surface naval platforms, including work tied to submarines and unmanned vessels, the company said. The targets have about 240,000 square feet of manufacturing space across multiple sites.
The companies supply mission-critical technologies and coatings, plus propulsion-related systems, according to a separate report of the announcement. Karman said it expects key Seemann and MSC leaders to remain in place after the deal closes.
Karman, which operates as Karman Space and Defense, designs and builds systems for launch vehicles, satellites and spacecraft, missile defense, hypersonic programs and unmanned aircraft systems, according to its company profile.
The transaction is expected to close in the first quarter of Karman’s fiscal 2026, subject to regulatory approvals and other conditions. Karman also reiterated its fiscal 2025 revenue and adjusted EBITDA guidance — a profit metric that strips out some costs — that it issued in November.
Still, the deal is not done. A regulatory delay, integration missteps, or higher-than-expected costs to fold in new plants and programs could cool the rally, while defense and space contractors remain exposed to shifts in U.S. government spending and contract timing.
