About

Air Industries Group is a manufacturer of precision components and assemblies for the aerospace and defense sectors. The company produces landing gears, flight controls, engine mounts, and parts for aircraft jet engines, ground turbines, and other complex machines. It operates as a Tier One and Tier Two supplier to original equipment manufacturers and also ships directly to the U. S. Government. Air Industries Group runs two state‑of‑the‑art manufacturing centers in Long Island, New York, and Barkhamsted, Connecticut, which house its legal subsidiaries Air Industries Machining (AIM), Nassau Tool Works (NTW), and Sterling Engineering Company (STE). The firm emphasizes a unwavering commitment to genuine quality and exceptional reliability, maintaining a record with no known incidents of part failure leading to a mission‑critical failure.

Air Industries Group generates revenue by selling its machined components and assemblies to aerospace and defense prime contractors under long‑term agreements, spot buys and other contracts. Its products are integrated into military aircraft, commercial aviation platforms, and ground‑based power generation systems. In 2025 the company reported net sales of $47.9 million, representing a modest increase from prior periods, while its funded backlog grew to $136.8 million, a 16.0% rise compared with the end of 2024. The total unfilled contract value, which includes the funded backlog and all potential orders against existing long‑term agreements, reached $270.1 million as of December 31, 2025. Bookings in fiscal 2025 amounted to $65.0 million, yielding a book‑to‑bill ratio of 1.36x, an improvement over the 1.29x ratio recorded in 2024. The company’s sales cycle varies from a few weeks to over a year depending on product complexity, and most orders stem from long‑term agreements that outline quantity and price for multi‑year shipments.

Within the aerospace and defense supply chain, Air Industries Group positions itself as a reliable source of high‑quality precision parts, often serving as the exclusive or primary supplier for specific components. The company competes against larger firms such as Monitor Aerospace (a division of GKN Aerospace), Hydromil (a division of Triumph Aerospace Group), Heroux Devetek, and Ellanef Manufacturing (a division of Magellan Corporation). Its competitive advantages stem from a long‑established history, a record of no mission‑critical part failures, domestic manufacturing facilities in New York and Connecticut, and ongoing investments in capital equipment and process improvements. In recent fiscal years the firm invested $3.3 million in 2025 and $2.3 million in 2024 in new property and equipment to enhance production efficiency, speed, and tolerance capabilities. These investments have enabled the company to increase output, expand the size of manufacturable products, and maintain close tolerances that are valued by customers. Additionally, Air Industries Group emphasizes a close‑knit workforce of approximately 160 employees, with specialized teams in manufacturing, quality control, administration, and sales, which supports consistent delivery of high‑reliability components.

Air Industries Group serves a diversified customer base that includes major defense contractors and commercial aviation manufacturers. Specific customers comprise RTX Corporation (including its Collins Aerospace and Pratt & Whitney business units), Lockheed Martin Corporation (via Sikorsky Aircraft), Northrop Grumman, General Electric Aerospace, GE Verona, and the U. S. Government through the Defense Logistics Agency. The company also supplies components to international governments and commercial airlines for use on military and civilian aircraft. In 2025 approximately 58.3% of net sales were attributed to end‑use on military aircraft, while the remainder came from commercial aviation and, to a lesser extent, ground‑based electricity generation. Air Industries Group has cultivated long‑standing relationships with these customers, often being selected as a sole or single source for high‑precision parts such as thrust struts for the Pratt & Whitney Geared Turbo‑Fan engine, landing gear for the UH‑60 Black Hawk and CH‑53K helicopters, and landing gear components for the F‑35 Lightning II and F‑18 Hornet aircraft. These relationships are reinforced by long‑term agreements that provide visibility into future demand and help secure repeat business.

Investment Thesis

▲ Bull case

The proposed merger with Tenax Aerospace represents a transformative strategic shift for AIRI that the market may be significantly underestimating. By combining AIRI's precision manufacturing capabilities with Tenax's special mission aviation business, the pro-forma entity is projected to generate over $210 million in revenue and Adjusted EBITDA exceeding $75 million for 2026, based on Tenax's current contract run rate and excluding one-time refinancing costs. This scale creates meaningful diversification beyond AIRI's historical reliance on component manufacturing, introducing higher-margin, recurring revenue streams from aircraft operations, maintenance, and specialized government contracts in ISR, fire suppression, and sensor testing. The combined entity's ability to offer end-to-end solutions—from manufacturing mission-critical components to operating the aircraft that use them—creates a unique value proposition in the aerospace and defense sector that could command premium valuations and win larger, more complex contracts previously inaccessible to either company alone. The transaction structure, which results in Tenax shareholders owning approximately 95% of the post-merger entity, effectively brings in a private equity-backed growth platform with strong government contracting expertise, while providing AIRI shareholders access to permanent capital and a public market vehicle for future growth initiatives. This is not merely a cost-saving merger but a strategic repositioning into higher-growth, defensible niches within defense and government aviation where barriers to entry are high and customer retention is strong due to mission-critical dependencies.
AIRI's current financial profile, while showing modest standalone performance, masks significant embedded value that could be unlocked through the merger's financial engineering and operational synergies. The pro-forma net debt of approximately $300 million (after expected reductions from cash flow and asset sales) against projected $210 million+ in revenue and $75 million+ in Adjusted EBITDA implies a net debt-to-EBITDA ratio of roughly 4.0x, which, while elevated, is manageable given the defensive nature of government contracts and the potential for rapid deleveraging through strong cash conversion. Importantly, the merger agreement includes provisions for refinancing AIRI's existing indebtedness at closing, which could lower overall interest costs if Tenax secures more favorable terms. Furthermore, the combined company's employee base of ~430—up from AIRI's current ~175—reflects not just scale but the integration of Tenax's specialized aviation operators and maintenance teams, enabling cross-selling opportunities where AIRI can manufacture components for Tenax-operated aircraft, thereby capturing more value across the product lifecycle. The leadership commentary emphasizes access to permanent capital and manufacturing scale as key tenax motivations, suggesting a clear path toward reinvestment in R&D, facility upgrades, and pursuit of next-generation special mission platforms that could drive long-term top-line expansion beyond current projections.
A critical but underappreciated catalyst lies in the contingent redemption right granted to existing AIRI shareholders, which could serve as a floor for downside risk while preserving substantial upside potential. Specifically, on the first anniversary of the merger, AIRI shareholders as of the pre-merger closing date retain the right to require redemption of their shares if the 20-day volume-weighted average price falls below 107.3% of the Debt Adjusted AIR Share Price (~$3.44), effectively creating a price support mechanism around $3.69. This structure, unusual in standard mergers, indicates Tenax's confidence in the combined entity's ability to deliver value and may reflect an intention to avoid excessive dilution while aligning long-term incentives. More importantly, it reduces the perceived risk for current AIRI shareholders contemplating the vote, potentially facilitating smoother approval and reducing post-merger selling pressure. Combined with the expectation of closing before June 30, 2026, and the absence of a financing contingency (unlike many SPAC-style deals), the transaction presents a relatively de-risked path to scale. If the combined company meets even 80% of its pro-forma EBITDA target, the implied valuation multiple would still be attractive relative to peers in aerospace manufacturing and defense services, suggesting the market may be pricing in excessive execution risk without adequately weighing the strategic logic of vertical integration in mission-critical aerospace systems.

▼ Bear case

Despite the optimistic pro-forma projections, AIRI shareholders face substantial dilution and uncertain value creation in a merger where they will own only approximately 5% of the combined entity, raising serious concerns about whether the transaction truly serves their interests or primarily benefits Tenax's owners. The issuance of roughly 112.5 million new shares to Tenax members—based on a Debt Adjusted AIR Share Price of $3.44—means that even if the combined company achieves its ambitious $210 million revenue and $75 million Adjusted EBITDA targets for 2026, the per-share accrual to existing AIRI shareholders would be minimal unless the market assigns a significant premium to the combined entity's strategic merits. Given AIRI's current market capitalization is likely far below the implied $387 million equity value (112.5M shares × $3.44) being effectively transferred to Tenax, the deal appears heavily skewed in favor of Tenax's stakeholders, particularly when considering that AIRI's standalone operations generated only $18.897 million in revenue and $4.347 million in Adjusted EBITDA for FY2025. This extreme imbalance suggests the market may be correctly skeptical about whether synergies can justify such a lopsided ownership transfer, especially when the combined company's success will depend heavily on Tenax's ability to integrate AIRI's manufacturing culture with its aviation operations—a transition fraught with operational risk.
The financial structure of the merged entity introduces significant leverage and refinancing risks that could undermine the projected cash flow stability, particularly given the current macroeconomic environment and sector-specific pressures. The pro-forma net debt of up to $300 million (after expected reductions) against projected $75 million+ in Adjusted EBITDA results in a leverage ratio near 4.0x, which leaves little room for error if government contract delays, supply chain disruptions, or slower-than-expected aircraft sales impact Tenax's contract run rate—a key assumption underpinning the 2026 projections. Furthermore, the refinancing of AIRI's existing indebtedness at closing assumes access to capital markets on favorable terms, yet the company's recent audit opinion emphasizing substantial doubt about its ability to continue as a going concern (as noted in its 2025 10-K) signals underlying financial fragility that may not be fully resolved by the merger. Tenax's own January 2026 refinancing, which incurred $80 million in new debt to purchase minority interests, adds further complexity and suggests its financial engineering may be aggressive. If interest rates remain elevated or if lenders impose stricter covenants post-merger, the combined company could face liquidity pressures that force asset sales or hinder investment in growth initiatives, directly contradicting the promised synergies.
Critical execution risks in the integration process are being insufficiently addressed in the forward-looking statements, particularly regarding cultural alignment, customer retention, and the realization of promised backlog conversion. AIRI operates as a precision manufacturer serving Tier 1 aerospace primes with long qualification cycles, while Tenax specializes in operating and maintaining specialized aircraft for government clients—a fundamentally different business model involving distinct regulatory requirements, risk profiles, and customer relationships. The assumption that these entities can seamlessly cross-sell (e.g., AIRI manufacturing parts for Tenax-operated aircraft) overlooks the likelihood that Tenax may already have established supply chains or prefer existing vendors due to certification and reliability concerns. Moreover, the merger does not alter AIRI's fundamental exposure to volatile defense budgets and congressional appropriations cycles, which remain subject to political shifts and sequestration risks. The forward-looking statements rely heavily on Tenax's current contract run rate, but special mission aviation contracts—while often enduring—are subject to recompete, performance-based penalties, and evolving threat landscapes that could reduce demand for platforms like airborne ISR or fire suppression. Without clear details on customer concentration, contract durations, or backlog visibility beyond Tenax's stated run rate, the market may be justified in viewing the pro-forma 2026 figures as aspirational rather than achievable, especially given the lack of substantive discussion about integration costs, employee retention challenges, or IT systems harmonization in the disclosed materials.
