Customers
Loar sells to aerospace OEMs, aftermarket channels, and defense customers that need qualified, highly reliable components. Its customer base is diversified across end markets and platforms, with no single customer representing more than 12% of 2025 net sales and the top five customers at 32%.
Buy components for new aircraft production, especially on major platforms like the Airbus A320 family and Boeing 737 family.
Buy replacement parts and support products for installed aircraft fleets to maintain airworthiness and uptime.
Buy niche parts and systems for private and light aircraft where qualification and reliability matter.
Buy specialized components for military aircraft and aerospace systems with long program lives.
Buy a small set of adjacent products outside aviation, representing a limited diversification outlet.
Strategy
Loar is focused on expanding organic growth through backlog conversion, new product development, and deeper penetration at existing customers. It also pursues acquisitions aggressively, using a lean operating structure to integrate niche brands and broaden its component portfolio while preserving financial flexibility.
Firm orders already in hand can support revenue growth without relying only on new wins.
Aftermarket sales are recurring and historically higher margin than OEM sales.
Buying niche brands adds product breadth, customer relationships, and cross-selling opportunities.
New content on existing platforms can deepen share and extend the installed base.
Geography
The filings do not provide a country-level revenue split, but Loar describes its business as global and tied to aircraft platforms and customers across the aerospace supply chain. Its exposure is shaped more by end-market mix and platform concentration than by a single geography, with international sales and operations noted as a risk area.
Risks
Loar is highly exposed to aerospace and defense demand, so disruptions in flight activity, OEM production, defense budgets, or customer profitability can affect sales. Its model also depends on qualified suppliers, customer concentration, acquisitions, and regulatory approvals, which can create operational and integration risk.
- Aerospace and defense end-market concentrationImpact: HighLikelihood: High
Most revenue comes from a single industry cluster, so shocks to aircraft production or flight hours can reduce demand.
Exposure - Customer concentrationImpact: HighLikelihood: Low
A limited number of customers account for a meaningful share of sales, increasing bargaining and volume risk.
Exposure: Top five customers were 32% of 2025 net sales
- Supply chain and input cost inflationImpact: MediumLikelihood: Medium
Specialized parts and certified materials can be hard to replace quickly, and inflation can compress margins.
Exposure - Acquisition execution and integrationImpact: MediumLikelihood: Medium
Growth strategy relies on buying and integrating niche businesses, which can create operational and valuation risk.
Exposure - Regulatory and certification dependenceImpact: MediumLikelihood: Medium
Aerospace components require lengthy qualification and approvals, making supplier replacement difficult.
Exposure - Leverage and liquidityImpact: MediumLikelihood: Low
Acquisition-driven growth has been funded with debt, so higher rates or weaker cash flow could constrain flexibility.
Exposure
Accounting
Judgemental itemsAcquired customer relationships and other intangibles rely on management forecasts and can be written down if expected cash flows weaken.
Impact: Could materially affect earnings and book value if acquired businesses underperform
Recent acquisitions add purchase accounting adjustments and amortization that affect comparability across periods.
Impact: Can change reported margins, depreciation/amortization, and growth rates
OEM and aftermarket sales have different margin profiles and shipment timing, affecting quarterly results.
Impact: Can create seasonality and period-to-period volatility
The company leases facilities and equipment through 2043, creating long-duration obligations and right-of-use assets.
Impact: Affects operating expenses, balance sheet liabilities, and leverage metrics
