Executive Summary / Key Takeaways

• Graham Corporation has engineered a strategic pivot from commercial-heavy cyclicality to defense-dominant stability, with defense revenue growing to 60% of sales and comprising 85% of a record $500 million backlog, creating multiyear revenue visibility that fundamentally alters the company’s risk profile.

• Margin inflection is underway but masked by mix effects: adjusted EBITDA margins have recovered from -3.4% in fiscal 2022 to over 10.7% in fiscal 2025, yet near-term gross margin pressure from defense material receipts obscures the underlying operational leverage as the company scales.

• The company’s 89-year heritage and sole-source positioning on critical Navy programs create an unassailable competitive moat in mission-critical turbomachinery and vacuum systems, while recent acquisitions (P3 Technologies, Xdot) deepen technological barriers to entry.

• A capital deployment wave ($15-18 million in fiscal 2026) targeting returns above 20% ROIC is building capacity for the next growth phase, including a new 30,000 sq ft Navy facility and cryogenic testing infrastructure that will operationalize by fiscal 2027.

• Valuation at 43x earnings and 34x EBITDA embeds high expectations; the investment thesis hinges on achieving management’s fiscal 2027 targets of low-to-mid teen EBITDA margins while navigating defense budget cyclicality and commercial energy market transitions.

Setting the Scene: From Industrial Cyclicality to Defense Moat

Founded in 1936 in Batavia, New York, Graham Corporation spent its first eight decades building a respectable but cyclical business supplying vacuum and heat transfer equipment to oil refineries, chemical plants, and industrial processors. This heritage endowed the company with deep engineering expertise in fluid dynamics and precision manufacturing, but it also chained Graham to the boom-bust cycles of commercial capital spending. Management’s strategic revelation began in fiscal 2022 with a deliberate “stabilize” phase that would remake the company’s identity. The portfolio transformation from 75% commercial/25% defense to a 40%/60% defense-led mix wasn’t merely a revenue shift—it was a complete rewiring of the company’s earnings quality and competitive positioning.

Why does this matter? Defense contracts, particularly for nuclear submarine propulsion and undersea power systems, carry decade-long program cycles, sole-source procurement status, and mission-critical performance requirements that render them immune to price competition. When a Virginia-class submarine needs a specialty pump that must function flawlessly 800 feet below the ocean’s surface for 30 years, the Navy doesn’t issue an RFP to low-cost bidders; it relies on proven suppliers with security clearances, validated designs, and qualified manufacturing processes. Graham’s Barber-Nichols subsidiary, integral to the Navy’s programs since the 1980s, provides exactly that moat. The backlog tripling from $138 million to $412 million by fiscal 2025 isn’t just a number—it represents locked-in revenue stretching up to six years forward, fundamentally reducing earnings volatility and justifying a higher valuation multiple than the commercial-equipment peers of its past.

The company now operates across three distinct segments: Defense (60% of revenue), Energy Process (35%), and Space (5%). This structure creates a diversified revenue base where the defense anchor provides stability while smaller, faster-growing space and alternative energy segments offer optionality. The Defense segment’s $40.8 million in Q2 FY26 sales, growing 31.9% year-over-year, demonstrates acceleration even against a tough prior-year comparison. Meanwhile, the Energy Process segment’s 10.5% growth to $21.3 million shows resilience despite management’s warnings of near-term traditional energy project scarcity. The Space segment, though small at $4 million quarterly revenue, has booked $22 million in new orders from six industry-leading customers—orders that will convert over the next 12-24 months, suggesting a near-term inflection point.

Technology, Products, and Strategic Differentiation: The Sole-Source Advantage

Graham’s competitive moat rests on two pillars: proprietary vacuum and turbomachinery technology, and a manufacturing infrastructure qualified for the world’s most demanding defense applications. The Barber-Nichols division’s turbomachinery expertise, honed through decades of submarine work, extends into commercial space propulsion systems where failure is not an option. The November 2023 acquisition of P3 Technologies added custom engineering capabilities in Jupiter, Florida, while the October 2025 Xdot Bearing Technologies purchase brought patented foil bearing designs that “deliver superior performance while reducing development and production costs.”

Why does foil bearing technology matter for investors? Traditional bearings require oil lubrication and have speed limitations; foil bearings enable oil-free rotation at extreme speeds with higher reliability and lower maintenance—critical attributes for rocket turbopumps, medical devices, and next-generation defense systems. Integrating Xdot’s technology with Barber-Nichols’ turbomachinery “significantly expands our ability to engineer and deliver advanced high-speed pumps, compressors and rotating systems.” This isn’t incremental improvement; it opens markets where Graham can be first-mover and establish new sole-source positions, creating fresh revenue streams with embedded pricing power.

The Energy Process segment’s NextGen steam ejector nozzle exemplifies technology-driven market expansion. Engineered to reduce steam consumption 20-30% while increasing system capacity, it targets a $50 million market opportunity over 5-10 years. For refineries facing carbon reduction mandates and energy cost pressure, this technology offers payback periods short enough to drive rapid adoption. A second order has already been received, with active pursuits domestically and in China, where authorities have a “big initiative to reduce steam consumption.” This matters because it shows Graham can monetize its core vacuum expertise beyond defense, creating commercial growth options that complement the stable defense base.

In defense applications, the moat deepens through qualification cycles that competitors cannot shortcut. The MK48 Mod 7 Heavyweight Torpedo program’s $25.5 million follow-on order in Q2, and $86.5 million in Virginia-class submarine orders year-to-date, reflect programs where Graham’s equipment is already qualified and field-proven. The Navy’s $13.5 million grant toward a $17.5 million advanced manufacturing facility in Batavia, plus a $2.2 million grant for radiographic testing equipment , demonstrates customer co-investment that locks in relationships and raises switching costs. When defense agencies fund your capacity expansion, they’re not shopping for alternatives.

Financial Performance: Margin Inflection Amid Mix Noise

Graham’s Q2 FY26 results tell a story of strategic execution obscured by temporary headwinds. Net sales rose 23% to $66.0 million across all segments, with defense leading at 32% growth. Yet gross margin compressed 220 basis points to 21.7%, and management explicitly attributed the decline to an “extraordinary high level of material receipts which carry a lower profit margin.” Why does this matter? Defense projects involve milestone-based revenue recognition where material procurement can create quarterly margin volatility, but the underlying project economics remain intact. The full-year gross margin guidance of 24.5-25.5% implies margin recovery in the second half as this material passes through the P& L, suggesting the Q2 dip is transitory rather than structural.

The more telling metric is SG&A leverage. Despite revenue growth and investments in operations, SG&A as a percentage of sales fell to 15.5% from 17.1% year-ago, evidencing that fixed overhead is being absorbed by higher volume. Adjusted EBITDA grew 12% to $6.3 million, with year-to-date margin expanding 40 basis points to 10.8%. This trajectory supports management’s confidence in achieving fiscal 2027 adjusted EBITDA margins in the low-to-mid-teens once the Barber-Nichols earnout bonus phases out by end of fiscal 2026. The earnout, which will not recur, has been dragging EBITDA by $6-7 million annually; its expiration creates a clear margin expansion catalyst.

Cash flow dynamics reveal the capital intensity of the growth strategy. Cash from operations dropped to $11.3 million in the first six months from $22.6 million prior, driven by working capital timing from accounts receivable collection. This isn’t a deterioration in business quality—it’s a natural consequence of rapid backlog growth and longer defense contract cycles. Capital expenditures jumped to $11.1 million from $6.5 million, funding the Batavia facility, cryogenic test stand, and production capacity in Arvada. With maintenance capex only $2 million annually but strategic capex running $15-18 million in fiscal 2026, investors must distinguish between discretionary growth investment and required sustaining spend. Management’s target of 7-10% of sales capex for “the next several years” signals a multiyear capacity build that should moderate once facilities are operational, freeing cash flow for returns or further M&A.

The balance sheet provides ample firepower for this investment cycle. Cash of $20.6 million, no debt, and $44.7 million available on the Wells Fargo (WFC) revolver give Graham a 0.3x leverage ratio versus a 3.5x covenant limit. This matters because it enables the company to self-fund growth without diluting shareholders or taking on financial risk, preserving optionality if attractive acquisitions emerge. Competitors like Flowserve carry 0.42x debt/capital and 0.29x debt/assets, while Chart Industries is more leveraged at 0.53x debt/capital. Graham’s conservative structure is a competitive advantage in cyclical markets where liquidity can become a strategic weapon.

Segment Dynamics: Defense Drives Stability, Space Offers Upside

Defense is the engine of Graham’s transformation. The segment’s $40.8 million Q2 sales (31.9% growth) and $86.5 million in Virginia-class submarine orders year-to-date demonstrate accelerating demand from the Navy’s submarine build schedule. With 85% of total backlog defense-related and conversion cycles up to six years, revenue visibility extends well beyond typical industrial equipment cycles. Management notes that “the programs we’re involved with are extremely long-standing and have great confidence long term,” making them resilient to government shutdowns or budget near-term noise. Advanced procurement funding often arrives years before ship approval, creating a buffer against political volatility.

The economic implication is profound: defense revenue carries lower gross margins than commercial work—hence the Q2 margin compression—but offers superior risk-adjusted returns due to predictability, sole-source pricing power, and aftermarket service streams. Aftermarket sales to defense and energy markets hit $9.8 million in Q2, consistent with record levels and up 15% year-to-date. Fleet maintenance opportunities are expanding as the Navy upgrades existing assets to extend service life from 30 years to “essentially new.” This creates a recurring revenue annuity atop the capital equipment base, improving margin quality over time.

Energy Process faces headwinds but holds strategic option value. Traditional refinery and chemical projects are scarce in the U.S., with new capital investment shifting to India and the Middle East. Graham’s “China for China” and “India for India” localization strategy mitigates tariff exposure while positioning for regional growth. More importantly, alternative energy opportunities are materializing: small modular reactor (SMR) activity is increasing, driven by AI data center power demands and crypto mining. Graham’s scope includes helium circulators, molten salt pumps, and future supercritical CO2 machines—technologies that could command premium pricing in a market projected to grow substantially. The segment’s modest 10.5% growth in Q2 masks this long-term optionality.

Space represents Graham’s highest-risk, highest-reward segment. Revenue is lumpy—$4 million in Q2, up 17% year-over-year, but flat on a six-month basis—yet the $22 million in new orders from six commercial space customers signals a potential inflection. These orders convert over 12-24 months, suggesting meaningful revenue acceleration in fiscal 2027. The segment serves launch providers and in-space systems where equipment must survive extreme conditions, creating natural barriers to entry. Barber-Nichols’ “decades-long reputation for performance in high-speed rotating equipment” and investments in cryogenic testing capacity position Graham as the go-to supplier as the commercial space market consolidates around reliable vendors. The risk is customer concentration: many space customers are unprofitable and require ongoing funding, making future revenue uncertain. However, the technology moat and qualification cycles provide downside protection—once designed into a rocket, switching suppliers is cost-prohibitive.

Capital Allocation: Building for the Next Decade

Graham’s $15-18 million fiscal 2026 capex plan represents 7-8% of guided revenue, elevated well above the $2 million maintenance level. Why spend aggressively now? The new 30,000 square foot Batavia facility, cryogenic propellant testing infrastructure in Florida, and advanced radiographic testing equipment are not capacity replacements—they’re strategic enablers of programs the Navy and space customers will rely on for decades. Management targets returns above 20% ROIC, implying these projects will generate $3-4 million in incremental annual operating income once fully operational by fiscal 2027 end.

The $13.5 million Navy grant covering most of the $17.5 million Batavia facility cost is particularly significant. It reduces Graham’s cash investment while contractually aligning the customer with long-term capacity. This co-investment model de-risks capex and creates switching costs for the Navy, which now has a vested interest in the facility’s success. Similarly, the $2.2 million defense customer grant for radiographic testing equipment funds quality enhancements for Columbia and Virginia-class submarine programs, embedding Graham deeper into the supply chain.

Competitors are not making comparable investments. Flowserve’s capex runs 1.6% of sales ($0.57 per share versus Graham’s $2.15), focusing on maintenance rather than growth. Chart Industries invests heavily but via debt-funded acquisitions, creating integration risk. Babcock & Wilcox can barely fund capex given negative cash flow. Graham’s ability to self-fund strategic expansion while maintaining net cash is a differentiator that will widen its moat.

Outlook and Execution Risk: Can Management Deliver?

Management’s fiscal 2026 guidance—$225-235 million sales, $22-28 million adjusted EBITDA—implies 10% revenue growth and 12% EBITDA growth at the midpoint. The decision to maintain guidance despite strong Q2 performance reflects timing, not weakness: “It’s just all timing… we’re tracking right on plan,” explained CFO Chris Thome. This matters because it shows management is not managing quarterly optics but building to a multiyear plan. The third quarter is seasonally weakest due to holidays and vacation, so full-year performance depends on Q4 execution.

More importantly, the fiscal 2027 goals of 8-10% organic revenue growth and low-to-mid teen EBITDA margins are credible because the building blocks are visible. The Barber-Nichols earnout bonus, which has been a $6-7 million annual EBITDA drag, phases out by end of fiscal 2026. The new Batavia facility becomes fully operational by end of fiscal 2026, adding capacity for Navy programs with embedded profit margins. The Florida cryogenic facility comes online by mid-calendar 2025, enabling space customer orders that have already been booked. These are not hockey-stick assumptions; they are de-risked by physical construction progress and customer co-investment.

The key execution variable is defense budget stability. CEO Matt Malone’s assessment that a government shutdown would have “minimal” impact reflects the strategic nature of submarine and torpedo programs, which are funded through advanced procurement and protected from continuing resolution pressures. A supplemental defense spending increase “takes pressure off probably all programs,” while a continuing resolution would mainly affect less strategic initiatives. This matters because it suggests Graham’s core programs—notably Virginia-class submarines and Columbia-class ballistic missile submarines—are prioritized even in budget-constrained environments.

Risks: What Could Break the Thesis

Government budget risk is material but manageable. While Malone downplays near-term shutdown impacts, a multi-year defense spending retrenchment would eventually affect shipbuilding schedules. The concentration risk—85% of backlog in defense—is double-edged: it provides stability but limits diversification. If geopolitical tensions ease and submarine build rates slow, Graham’s growth trajectory would materially decelerate. This is the central risk to the 8-10% long-term organic growth target.

Commercial cyclicality remains a concern. The Energy Process segment’s exposure to refining and chemical capex means it could face headwinds if global recession reduces industrial demand. Management notes “extended decision cycles on certain large global capital projects,” and while SMR and hydrogen opportunities offer long-term growth, they are not yet material to near-term results. A prolonged energy downturn could pressure margins as pricing competition intensifies.

Operational execution risks are rising. The direct labor force is up 10% year-over-year to meet demand, and management notes the market for new employees has “softened,” aiding recruitment. However, scaling production for six-year defense programs while simultaneously ramping space deliveries requires precise project management. Any quality issues or delivery delays on Navy programs could jeopardize sole-source positions. The Q2 margin compression from material receipts illustrates how mix shifts can create quarterly volatility, and while management has guided to full-year margin recovery, sustained defense-heavy mixes could structurally cap gross margins below historical peaks.

Legal and compliance overhangs are minor but worth monitoring. Asbestos-related lawsuits carry the standard “could have a material adverse impact” boilerplate, though management believes resolution will not materially impact financials. The India whistleblower investigation, which uncovered $150,000 in misconduct over four years, was self-reported and resolved with terminations. These issues are immaterial to the investment thesis but reflect governance challenges inherent in global operations.

Competitive Context: Niche Depth vs. Scale Breadth

Graham occupies a unique position among industrial equipment manufacturers. Unlike Flowserve , which competes broadly in pumps and valves with 33.7% gross margins but lower growth (6% bookings growth in Q3 2025), Graham’s defense focus creates a protected sub-market with sole-source pricing. Flowserve’s diversification provides stability but limits margin expansion, while Graham’s concentration creates torque to defense spending. Flowserve’s debt-to-capital ratio of 0.42x versus Graham’s 0.05x gives Graham superior financial flexibility to invest through cycles.

Chart Industries , with 33.8% gross margins, overlaps in cryogenic equipment but serves the volatile LNG and energy transition markets. Chart’s Q3 2025 orders surged 43.9% but were offset by a $271 million one-off loss from acquisitions, highlighting integration risks Graham avoids through organic capacity expansion. Chart’s 1.14x debt-to-equity ratio constrains its ability to fund R&D, while Graham’s net cash position enables investment in NextGen nozzle and SMR technologies that could disrupt Chart’s addressable market.

Babcock & Wilcox represents the value destruction Graham’s transformation avoids. BW’s -20% net margins and negative operating cash flow stem from legacy coal exposure and restructuring costs. While both companies serve power markets, Graham’s pivot away from commoditized thermal equipment toward mission-critical defense protects it from structural decline. BW’s (BW) 2.0x debt-to-capital ratio and -37.8x EV/EBITDA multiple illustrate the fate Graham escaped.

Thermon Group’s 45.3% gross margins and 11.6% net margins demonstrate the profitability potential of specialized thermal solutions, but its focus on heat tracing for maintenance markets limits growth to mid-teens. Graham’s space segment, while smaller, offers higher growth potential as commercial launch markets scale. Thermon’s lack of defense exposure makes it a pure-play industrial capex story, while Graham’s defense moat provides valuation support.

Valuation Context: Premium for Predictability

Trading at $54.00, Graham’s 43.4x P/E and 2.6x P/S multiples embed expectations of sustained double-digit earnings growth. The EV/EBITDA multiple of 33.73x is elevated versus industrials but reflects the backlog quality and sole-source moat. The Seeking Alpha critique that the stock trades at a “70% premium on an EBITDA multiple basis and offers negative FCF yield” highlights a key risk: current free cash flow is negative due to the heavy capex cycle, masking underlying earnings power.

Why does this matter? Valuation multiples are measuring current profitability against a future state that requires capital investment. Once the Batavia and Florida facilities are complete, capex should normalize to 2-3% of sales, unleashing free cash flow conversion. Management’s $22-28 million adjusted EBITDA guidance for fiscal 2026 represents 10-12.5% EBITDA margins, with the path to low-mid teens by fiscal 2027 de-risked by earnout elimination and capacity absorption. If achieved, EBITDA could approach $30-35 million on $235 million revenue, implying a more reasonable 16-19x forward EV/EBITDA multiple.

Peer comparisons are instructive. Flowserve (FLS) trades at 19.5x P/E but grows slower and carries more debt. Chart Industries (GTLS) trades at 137x P/E due to acquisition-related losses, not operational strength. Thermon’s (THR) 18.9x P/E and 2.19x P/S are closest to Graham’s metrics but lack defense growth drivers. Graham’s premium reflects its transformation trajectory and margin expansion potential, not current earnings power.

The balance sheet is pristine: $20.6 million cash, 0.05x debt-to-capital, and $44.7 million revolver availability provide multiple years of investment runway. Interest coverage of 88.7x is academic given minimal debt. This financial conservatism means dilution risk is low and the company can weather defense budget cycles without distress.

Conclusion: Execution at a Premium

Graham Corporation has engineered one of the most compelling strategic turnarounds in the industrial equipment sector, pivoting from commoditized commercial markets to mission-critical defense programs that offer sole-source pricing and multiyear revenue visibility. The 89-year heritage in vacuum and turbomachinery technology, combined with $500 million in backlog and 85% defense concentration, creates a durable moat that competitors cannot replicate without decades of qualification and relationship building.

The financial trajectory supports the narrative: EBITDA margins have recovered from negative territory to over 10% and are poised to expand into the low-mid teens as earnout expenses phase out and new capacity absorbs fixed costs. The heavy capex investment, while pressuring near-term free cash flow, is building physical and technological infrastructure that will generate returns above 20% ROIC, creating a foundation for 8-10% organic growth through fiscal 2027.

The investment thesis hinges on two variables: flawless execution on Navy program deliveries to maintain sole-source positions, and successful commercialization of NextGen nozzle and SMR technologies to offset traditional energy cyclicality. The valuation premium leaves no margin for error—a defense budget retrenchment or production quality issue could compress multiples by 30-40%. Conversely, achieving the fiscal 2027 targets while demonstrating sustained free cash flow generation could justify current valuations and provide 20-30% upside as the market re-rates the stock from cyclical industrial to mission-critical defense technology platform.

For discerning investors, Graham offers a rare combination of transformation, moat, and margin inflection—at a price that demands perfection but rewards execution with predictable, high-quality earnings growth.
