Business Overview: Graham Corporation (NYSE: GHM)

---

Executive Summary

Graham Corporation designs and manufactures mission-critical fluid, power, heat transfer, and vacuum technologies for demanding end markets, chiefly U.S. Navy nuclear and non-nuclear propulsion programs, space, defense, and energy/petrochemical processing. Headquartered in Batavia, New York, Graham has transformed itself over the past several years from a refining-and-petrochemical-equipment supplier into a defense-first business, aided by its 2023 acquisitions of Barber-Nichols and P3 Technologies, specialty turbomachinery makers serving naval, space, and new-energy markets.

In fiscal 2024 (ended March 31, 2024), Graham generated a record $185.5 million in net sales, up 18% year over year, and $4.6 million in net income, with gross margin expanding to 21.9%. Defense now accounts for roughly 54% of revenue, up from about 25% before the Barber-Nichols acquisition, while a record $390.9 million backlog — more than two times annual revenue — gives the business unusually high visibility for a company of its size.

1. Core Business Model & How They Work

Graham engineers highly customized equipment for applications where failure is not an option — naval nuclear propulsion, submarine systems, and large-scale industrial processes — then sustains relationships through decades-long aftermarket and spares support.

[ Win long-cycle defense/energy program contracts ] ➡️ [ Custom-engineer vacuum/heat-transfer/turbomachinery equipment ] ➡️ [ Deliver against multi-year program schedules ] ➡️ [ Build backlog from program wins ] ➡️ [ Decades of aftermarket spares/service revenue ]

Key operational drivers:

1. Defense as the primary growth engine: U.S. Navy carrier, submarine, and torpedo propulsion and power programs now drive the majority of revenue, a structural shift from Graham's historical refining/petrochemical base.
2. Barber-Nichols and P3 Technologies acquisitions: These specialty turbomachinery businesses (serving space, cryogenic, defense, and new-energy markets) accelerated Graham's pivot toward higher-growth, higher-margin defense and space end markets.
3. Record backlog as a visibility anchor: A $390.9 million backlog — more than double fiscal 2024 revenue — reflects multi-year defense program commitments that provide revenue visibility most small-cap industrials lack.
4. Margin expansion through mix shift: Gross margin rose 570 basis points to 21.9% in fiscal 2024, driven by the higher-margin defense and space mix displacing lower-margin legacy refining work.

Defense (~54% of fiscal 2024 sales)

Naval nuclear and non-nuclear propulsion, power, and thermal-management systems for U.S. Navy carrier, submarine, and torpedo programs — the largest and fastest-growing end market.

Refining (~16% of fiscal 2024 sales)

Surface condensers, ejectors, and vacuum systems for oil refining — Graham's historical core business, now a much smaller share following the defense-driven mix shift.

Space

Propulsion, power, cooling, and life-support systems, served principally through the Barber-Nichols and P3 Technologies subsidiaries.

Chemical, Petrochemical, and New Energy

Equipment for fertilizer, ethylene, and methanol facilities, plus emerging applications in hydrogen and other new-energy processes.

4. Competitive Landscape

Graham competes against both large diversified industrial/defense contractors and smaller specialty equipment makers, with its position varying significantly by end market.

         Low ─────────────────────────────── High
    High │                              [GRAHAM]
         │                  [Large defense primes]
  SCALE  │        [Legacy refining equipment makers]
    Low  │

• Defense/Navy propulsion: Competes for subcontracted and direct program work against other specialized naval equipment suppliers, often as a trusted, qualified vendor within a limited supplier base that the Navy has already vetted — a structural advantage given the long qualification cycles in defense procurement.
• Refining/petrochemical: Competes with other vacuum and heat-transfer equipment makers in a mature, slower-growth market.
• Space/turbomachinery: Competes with specialty aerospace and cryogenic equipment suppliers, where Barber-Nichols' decades of engineering experience is a differentiator.

Two customers each exceeded 10% of revenue in fiscal 2024, reflecting meaningful customer concentration tied to large defense program relationships — a double-edged characteristic that provides revenue visibility but also concentration risk.

5. Strategic Strengths & Risks

Strengths

• Record backlog and revenue visibility: A $390.9 million backlog (more than 2x annual revenue) provides unusual visibility into multi-year revenue for a company of Graham's size.
• Structural defense tailwind: U.S. Navy shipbuilding and submarine programs are long-duration, bipartisan-supported priorities, giving Graham's largest end market durable demand.
• Successful acquisition integration: Barber-Nichols and P3 Technologies have meaningfully diversified and improved Graham's margin mix since being acquired.
• Qualified-vendor status in defense: Long qualification cycles for naval nuclear suppliers create a real barrier to new entrants competing for the same programs.

Risks

• Customer concentration: Two customers exceeding 10% of revenue each means program delays, budget cuts, or contract losses at either customer could materially affect results.
• Small absolute scale: At under $200 million in annual revenue, Graham remains a small-cap industrial company, limiting its ability to self-fund large capital projects or weather prolonged program disruptions.
• Execution risk on backlog conversion: A backlog more than double annual revenue is only valuable if Graham can convert it into revenue on schedule, which depends on execution, supply chain, and customer program timing.
• Legacy refining exposure: The remaining ~16% refining-exposed revenue is tied to a mature, cyclical end market with limited structural growth.

7. Summary Conclusion

Graham Corporation has re-engineered itself from a legacy refining-equipment supplier into a defense-and-space-focused specialty equipment maker, a shift anchored by the Barber-Nichols and P3 Technologies acquisitions and validated by a record backlog more than double annual revenue. The business benefits from the long qualification cycles and sustained government funding that characterize U.S. Navy propulsion programs, giving it real, if narrow, structural protection against new entrants. The main risks are the flip side of its strengths: meaningful customer concentration in a handful of large defense programs, and the need to execute flawlessly in converting a large backlog into delivered, profitable revenue over the coming years.
