Graham Corp (GHM -14%) is heading lower despite wrapping up FY26 on a solid note. This supplier of fluid, power, heat transfer and vacuum technologies reported a sold EPS beat for Q4 (Mar). Revenue rose 13.0% yr/yr and 18% sequentially to $67.1 mln. This was a good bit above analyst expectations, but a slowdown from Q3's 21% yr/yr growth. We also got our first look at FY27 revenue guidance at $285-295 mln (+16-20%). While it was above analyst expectations, we think investors were looking for a better number given positive macro factors in terms of rising defense budgets and expanding space opportunities. We think today's weakness is mostly related to the FY27 guidance.

• Backlog and orders: Full-year backlog reached a record $532.6 mln, up 29% yr/yr, supported by record full-year orders of $359 mln and a 1.5x book-to-bill, reinforcing that demand remains healthy beyond the quarter.
• Growth quality: Fiscal 2026 revenue rose 17% to a record $245.3 mln, while adjusted EPS increased 13% to $1.40 and adjusted EBITDA climbed 16% to $26.0 mln, showing the company is converting top-line growth into higher earnings.
• FY27 framework: In addition to revenue guidance of $285-295 mln, Graham said it sees FY27 adjusted EBITDA of $35-40 mln, implying another year of meaningful operating growth if execution holds.
• Portfolio expansion: Graham highlighted the completed FlackTek acquisition, which adds advanced mixing and materials processing as a third core technology platform and broadens its capabilities across defense, space, energy, and industrial markets.
• Valuation/setup: The stock entered the report near record highs after a strong recent run, while trailing fundamentals show EV/EBITDA of 59.7x and free cash flow yield around 0%, leaving less room for an only modest guidance upside.

Briefing.com Analyst Insight

A key part of Graham story is the company's increasing leverage to defense and naval programs. Graham's products are often embedded in highly specialized systems where reliability and engineering expertise matter more than price, creating barriers to entry and supporting favorable competitive positioning. Defense budgets remain focused on fleet modernization, submarine construction, and broader national security initiatives, investors have been assigning greater value to suppliers like Graham. The space market also represents an underappreciated growth driver. Increased government and commercial investment in launch systems, satellites, and space infrastructure has expanded demand for specialized thermal management and vacuum technologies, areas where Graham has good exposure. Meanwhile, Graham continues to benefit from energy and industrial markets that require highly engineered equipment for demanding operating environments. With all of this as context, we think investors are viewing the FY27 guidance as a bit underwhelming.
