Airlines and aircraft repair companies buy HEICO’s replacement parts as lower-priced alternatives to parts from the original manufacturers. Its Flight Support Group supplies FAA-approved jet-engine and aircraft components, repairs and overhauls components, and distributes parts. This group generates most of HEICO’s sales, with replacement parts its largest business; it also supplies military aircraft operators and aerospace manufacturers. Demand depends on aircraft remaining in service and needing maintenance: aviation downturns, fleet retirements and prolonged groundings can reduce orders. Replacement parts must meet airworthiness requirements, and repair and overhaul operations require FAA certification.
HEICO’s Electronic Technologies Group sells specialized electronic components that customers build into larger equipment, primarily for defense, space and aerospace applications. These include power-conversion equipment, microwave products and avionics designed for demanding operating conditions. Military agencies, defense contractors and satellite and spacecraft manufacturers provide a large share of this group’s sales, making defense and space budgets important to demand.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
HEICO’s aftermarket results hinge on aircraft utilization and taking replacement-part business from engine makers, including Rolls-Royce, an important rival missing from this list.
TransDigm Group competes for aircraft replacement spending with HEICO, supplying proprietary components for commercial and military aircraft where HEICO sells replacement parts and electronics. Its replacement sales of pumps, valves and power-control components are worth watching for demand in these overlapping markets.
GE Aerospace competes with HEICO for airlines’ and repair shops’ engine-parts and maintenance spending: GE sells original-engine parts and servicing, while HEICO offers lower-cost replacement parts and repairs. GE’s commercial spare-parts and service sales offer a view of the engine aftermarket demand both pursue.
RTX competes with HEICO for aviation customers’ parts and repair spending through Pratt & Whitney engine parts and Collins Aerospace components, against HEICO’s replacement parts, avionics and repairs. Pratt & Whitney’s PW1100G-JM shop-visit output rose approximately 26% year over year in 2025, a concrete measure of activity in its engine maintenance network.
VSE Corp sells aircraft parts and maintenance, repair and overhaul services to the airline, government and maintenance-provider markets that also pay HEICO for parts and repairs. Its aviation parts and service revenue is a useful check on spending by these shared customer groups.
AAR Corp. competes with HEICO’s replacement-part, distribution and repair businesses by supplying aircraft parts and component maintenance to commercial and government customers. Its often-exclusive distribution of new original-manufacturer parts makes those sales worth watching alongside HEICO’s lower-priced replacements.
FTAI Aviation Ltd. gives airlines alternatives to HEICO’s replacement parts and repairs by refurbishing and selling commercial engine modules and aftermarket parts, and exchanging engines for sale or lease. Its CFM56-5B, CFM56-7B and V2500 engine-products business is the relevant line to watch for maintenance spending on mature engines.
StandardAero, Inc. and HEICO both earn money repairing aircraft engine components for commercial, military and business aviation customers. StandardAero’s component-repair business is the closest comparison for demand reaching HEICO’s engine-component repair operations.
Loar Holdings Inc. and HEICO both manufacture niche aircraft components and sell replacements into commercial and defense aviation markets. Aftermarket products supplied approximately 55% of Loar’s 2025 net sales, making that business a useful comparison for HEICO’s replacement-part demand.
Honeywell competes for aircraft avionics, power-system and component-maintenance spending with HEICO’s avionics, electronic products and repair services.
Woodward overlaps with HEICO in aircraft control components and aftermarket services, selling control systems to aircraft equipment makers and repairs to end users where HEICO repairs fuel controls, actuators and other components. Woodward’s aerospace maintenance and replacement business is more relevant to this tie than its industrial sales.
Teledyne Technologies competes with HEICO for aerospace and defense electronics spending through overlapping aircraft information systems, interconnects and satellite communications components. Its Aerospace and Defense Electronics sales are the relevant comparison for HEICO’s electronic-component business, rather than Teledyne’s larger imaging business.
Curtiss-Wright competes for aerospace and defense customers’ spending with HEICO, selling defense electronics and aerospace components that overlap with HEICO’s embedded computing, electronics and aircraft-component products.
Howmet Aerospace and HEICO share exposure to aircraft-engine demand across its life: Howmet sells manufactured engine components, while HEICO sells replacement parts to airlines and repair companies. Howmet’s Engine Products sales, including airfoils and rolled rings for commercial and defense aircraft engines, are the relevant business to watch.
Ducommun Incorporated competes with HEICO for aerospace and defense customers’ component spending through interconnects, microwave products, lightning protection and composite structures. Its electronics and structural-product sales provide separate comparisons for HEICO’s electronic products and specialty aerospace components.
TAT Technologies Ltd and HEICO both earn revenue overhauling aircraft and engine components for aviation customers, including work on auxiliary-power-unit-related equipment. TAT’s Piedmont auxiliary power unit maintenance and Turbochrome engine-component overhaul businesses are the closest areas to watch alongside HEICO’s repairs.
AerSale Corporation offers mid-life commercial aircraft owners and operators usable secondhand parts and technical services that compete with HEICO’s new replacement parts and repairs. Its sales of parts recovered by dismantling aircraft and engines show the used-parts alternative competing for these customers’ maintenance budgets.
GE Aerospace earningsGE
GE Aerospace’s commercial engine-parts and service sales show how airlines and repair shops are spending in the aftermarket where HEICO also competes.
Focus on GE Aerospace’s commercial spare-parts and service sales, not its company-wide results. Growth would point to active spending in the engine aftermarket, but would also show GE winning sales there; it would not prove HEICO gained share. Weakness would suggest softer demand in a market both companies serve. The report gauges the size of the opportunity, not HEICO’s share of it.
Teledyne Technologies Incorporated earningsTDY
Teledyne Technologies’ Aerospace and Defense Electronics business shows how customers are spending on electronics in markets where HEICO’s Electronic Technologies Group competes.
Watch Teledyne Technologies’ Aerospace and Defense Electronics sales, not its larger imaging business. Strength would signal continued customer spending in markets that overlap with HEICO’s Electronic Technologies Group; weakness would point to pressure on that shared demand. It is a read on the market, not a measure of HEICO’s own orders.
Fed Interest Rate Decision
HEICO’s $960 million revolving-facility borrowing links Fed rate decisions to the interest it pays: higher rates can raise that funding cost, while lower rates can reduce it.
Expected4.0%Last release4.0%
If it comes in above expectations
If the Fed’s rate is higher than expected, interest on HEICO’s revolving borrowing may rise, leaving less of its business earnings after financing costs.
If it comes in below expectations
If the Fed’s rate is lower than expected, interest on HEICO’s revolving borrowing may fall, leaving more of its business earnings after financing costs.
StandardAero, Inc. earningsSARO
StandardAero’s engine-component repair business shows whether aviation customers are sending work to repair shops, a source of revenue for HEICO too.
Watch whether StandardAero’s component-repair business strengthens, alongside any reported change in repair revenue. Growth would suggest more work is reaching aviation repair shops, a positive signal for demand for HEICO’s engine-component repairs; weakness would suggest the repair market may be cooling. Their customers and repair work differ, so this is an industry signal, not a substitute for HEICO’s own figures.
HEICO CORP earningsThis company
HEICO’s Flight Support Group sells aircraft replacement parts and repair services, and this report will show whether sales growth is still translating into profit.
Read FSG sales growth alongside its operating margin, the share of sales left after operating costs. Rising sales with a steady or higher margin mean demand for HEICO’s parts and repairs is still turning into profit; slower sales or a falling margin means growth or profitability is weakening. The key is whether HEICO’s aviation aftermarket business can grow while protecting its margins.
