Loar Holdings Inc. designs manufactures and sells niche aerospace and defense components that are essential for many aircraft platforms. The company concentrates on mission critical highly engineered solutions that contain significant intellectual property. Its product line includes auto throttles lap belt airbags two and three point seat belts water purification systems fire barriers polyimide washers and bushings latches interior securing devices hold open and tie rods temperature and fluid sensors and switches carbon and metallic brake discs fluid and pneumatic ice protection RAM air components sealing solutions motion and actuation devices customized edge lit panels and knobs announcers for incandescent and LED illuminated pushbutton switches high performance fans and cooling devices lighting human machine interface products and bespoke lighting systems among others. Loar serves three core end markets commercial aviation business jet and general aviation and defense. It has built long standing relationships with major aerospace and defense original equipment manufacturers airlines defense contractors and maintenance repair and overhaul providers. The company operates with a lean entrepreneurial structure that emphasizes local autonomy and clear communication across its brands. As of the end of 2025 Loar employed approximately 1700 full time part time and temporary workers and held 130 issued patents with additional pending applications.
Loar generates revenue from the sale of its proprietary aerospace and defense components. About eighty nine percent of 2025 net sales came from proprietary products where the company believes it holds market leading positions. Approximately fifty five percent of 2025 net sales were derived from aftermarket parts and services which provide predictable recurring revenue and historically yield higher margins than original equipment manufacturer sales. The remaining revenue comes from OEM sales to aircraft producers. The firm's revenue is diversified across end markets with roughly forty five percent from commercial aviation twenty five percent from business jet and general aviation twenty five percent from defense and five percent from non aviation activities. Revenue is also spread across product categories applications customers and aircraft platforms. No single customer accounted for more than twelve percent of 2025 net sales and the top five customers together contributed about thirty two percent of sales. No individual aircraft platform represented more than seven percent of revenue with the Airbus A320 family and Boeing 737 family being the two largest platforms. This diversification reduces concentration risk and supports stable cash flow.
Loar occupies a strong niche in the fragmented aerospace and defense component sector. Its competitive advantage stems from the difficulty of replicating its highly engineered products and the costly qualification process that new entrants must undergo. The lengthy certification procedures involving multiple tests and financial commitments from both suppliers and original equipment manufacturers create high barriers to entry that protect Loar's market position. The company's long standing relationships with major OEMs tier one and tier two suppliers and airlines reinforce its role as a trusted supplier. Loar competes on engineering capability product quality responsiveness and the ability to provide customized solutions rather than on price alone. The firm's diversified revenue base across end markets products customers and platforms lessens vulnerability to cyclical downturns in aircraft production. Loar's disciplined acquisition strategy has added twenty companies since 2012 with eighteen successfully integrated and recent additions of LMB in December 2025 and Harper Engineering in January 2026. The company's leadership team possesses deep industry experience with many members having worked together for over thirty years at prior firms. Loar maintains a lean organizational structure with few management layers which facilitates quick decision making and effective integration of acquired businesses. As of the end of 2025 the firm held 130 issued patents and had additional pending applications which further protect its proprietary technology.
Loar serves a wide range of customers that include major aircraft manufacturers commercial airlines business jet operators defense contractors and various maintenance repair and overhaul organizations. The company's sales are not concentrated with any single customer exceeding twelve percent of net sales and the top five customers together representing roughly thirty two percent of revenue. Long term contracts and repeat orders are common due to the critical nature of the components Loar supplies. The firm's exposure is spread across many aircraft platforms with no platform surpassing seven percent of sales and the two largest platforms being the Airbus A320 family and the Boeing 737 family. This broad customer and platform base helps Loar maintain steady relationships and gives it insight into emerging opportunities through direct dialogue with its clients. The company's focus on reliability on time delivery and tailored solutions has fostered lasting partnerships that contribute to its resilient financial performance.

Investment Thesis
▲ Bull case
Loar Holdings Inc. is positioned to leverage its proprietary product portfolio to capture long-term annuity streams from commercial aircraft platforms, with over two-thirds of its $700 million new business pipeline tied to original equipment (OE) wins that will generate decades of aftermarket revenue through repair and replacement cycles. This structural advantage is reinforced by the company’s demonstrated ability to qualify new parts in the first half of 2026, which will fuel increased sales starting in the second half of the year and compound through 2027 and beyond. Management emphasized that winning an OE part is not a one-time sale but creates a sustainable revenue stream as aircraft enter their aftermarket phase, directly supporting their long-term growth thesis. The record backlog in defense products despite Q1 sales decline further validates the resilience of their customer relationships and the underlying demand strength in proprietary products, which are insulated from competitive bidding due to high barriers to entry. This annuity-driven model transforms near-term OE wins into multi-decade cash flows, a dynamic that is underappreciated by the market’s focus on quarterly volatility in defense sales and underestimates the compounding effect of their pipeline conversion over time.
Loar Holdings Inc. is executing a disciplined capital allocation strategy that combines organic new business growth with selective M&A to drive sustained margin expansion and EBITDA accretion, with a proven track record of doubling EBITDA within three to five years post-acquisition. The company’s recent acquisitions of LMB and Harper Engineering—despite Harper’s initial margin dilution—are already contributing to operating leverage and strategic value driver execution, as evidenced by the 290 basis point year-over-year increase in adjusted EBITDA margin to 40.5% in Q1 2026. Management’s explicit commitment to one to two acquisitions annually over the next decade, supported by a large and active pipeline of high-IP suppliers, provides a structural catalyst for inorganic growth that complements their organic 10%+ top-line and 15%+ EBITDA growth targets. This dual-engine approach—organic innovation via proprietary product development and inorganic scale via accretive M&A—creates a self-reinforcing cycle where acquired capabilities enhance the new business pipeline, and pipeline successes improve acquisition targeting. The market is underestimating the durability of this model, which has delivered over 30% CAGR in sales and 40% in adjusted EBITDA since inception, and fails to recognize that margin expansion is being driven by structural factors like pricing power from proprietary content and productivity initiatives, not temporary tailwinds.
Loar Holdings Inc. benefits from a secular growth tailwind in the global aerospace and defense market, underpinned by record aircraft backlogs at Airbus (~9,000 planes) and Boeing (~7,000 planes), representing over ten years of production at current rates, which ensures sustained demand for its commercial OE products well into the 2030s. This is amplified by rising defense spending globally, with European nations allocating the highest percentage of GDP to military in decades and the U.S. defense budget expanding, creating a multi-year tailwind that management expects to drive mid-single-digit defense sales growth in 2026 despite Q1 lumpiness. The company’s balanced portfolio—approximately 50% aftermarket—provides resilience against cyclical swings, as evidenced by commercial OE and aftermarket growth offsetting defense weakness in Q1, and its ability to flex value drivers (price over inflation, operating leverage, productivity) ensures margins remain intact even amid macro volatility. Unlike pure-play defense or commercial suppliers, Loar’s diversified exposure allows it to capture growth across all phases of the aircraft lifecycle, and its proprietary content creates pricing power that insulates it from commoditization pressures. The market is overlooking how these structural industry shifts—long aircraft lifecycles, increasing global defense budgets, and aging commercial fleets—are not temporary but foundational to demand for the next decade, providing a durable foundation for Loar’s guided 10%+ organic sales and 15%+ organic EBITDA growth.

Loar Holdings Inc.’s reliance on timing-sensitive certification processes, particularly FAA approvals for proprietary products like brakes, introduces significant execution risk that could delay revenue recognition from its $700 million new business pipeline, with management acknowledging that FAA delays have slowed certification twice since going public and that four of eleven brake platforms remain pending certification within the next 12–18 months. While the company frames timing delays as temporary and maintains that the opportunity set remains intact, the market may be underestimating the potential for prolonged regulatory holdups—especially given increasing scrutiny on aviation safety post-pandemic—and the risk that customer pull mechanisms could weaken if certification timelines extend beyond expected windows, forcing customers to seek alternative suppliers or delay platform upgrades. This is compounded by the fact that revenue from new business does not begin immediately upon certification but phases in over time, meaning even successful certification may not translate to meaningful sales contribution until 2027 or later, creating a gap between pipeline visibility and near-term financial impact that could disappoint investors expecting quicker conversion.
Loar Holdings Inc.’s margin expansion narrative faces headwinds from rising interest expenses and the dilutive impact of acquisitions, as evidenced by the $4 million decrease in GAAP net income in Q1 2026 despite a $5 million increase in adjusted net income, driven by higher interest and non-cash acquisition-related charges totaling $11 million from the LMB and Harper Engineering deals. Although management highlights operating leverage and price-over-inflation as margin drivers, the company’s guidance assumes no additional acquisitions for the full year, yet explicitly states its “drumbeat is to complete one or two acquisitions each year,” creating a contradiction where future margin accretion depends on deals that are inherently dilutive in the short term. The market may be ignoring the cumulative effect of repeated acquisitions on interest expense, amortization (now up $5 million), and integration costs, which could erode the benefits of organic margin growth if acquired businesses fail to deliver EBITDA doubling within the promised three-to-five-year window—a risk heightened by the increasingly disparate quality of acquisition targets in a frothy aerospace M&A market.
Loar Holdings Inc.’s defense end market remains vulnerable to lumpy ordering patterns and geopolitical unpredictability, with Q1 2026 sales declining 2% year-over-year due to deferred orders on proprietary products like F-18 brakes and RC-135 autothrottle, and management’s expectation of a return to “habitual” ordering patterns relies on historical behavior that may not hold amid evolving global conflict dynamics. While the company cites record defense backlog at quarter-end as a positive signal, the fact that this backlog did not translate into Q1 sales highlights the disconnect between order timing and revenue recognition, and the market may be underestimating the risk that prolonged geopolitical tension could shift customer priorities toward immediate consumables over longer-lead-time proprietary components, or that budget reallocations could favor competing suppliers with faster delivery cycles. Furthermore, Loar’s reliance on the U.S. and allied defense budgets exposes it to potential policy shifts—such as defense spending freezes or reallocation toward domestic priorities—that could abruptly reverse the multi-year growth tailwinds management assumes, especially given that approximately 2.5% of revenue comes from conflict-affected regions where even minor escalations could disrupt supply chains or customer operations.
