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 report will show whether airlines and repair shops are spending more on engine parts and service, a demand signal for HEICO's engine aftermarket business.
Watch GE Aerospace's commercial engine spare-parts and service sales. Growth would point to solid demand from airlines and repair shops, a helpful backdrop for HEICO's Flight Support parts and repair business; a decline would suggest the shared aftermarket may be weakening. GE's results do not prove how HEICO's own sales or market share changed. The takeaway is the direction of engine-aftermarket demand, not whether HEICO won the business.
Teledyne Technologies Incorporated earningsTDY
Teledyne Technologies' aerospace and defense electronics sales will show whether customers are spending more or less in markets that overlap with HEICO's Electronic Technologies Group.
Focus on Teledyne's Aerospace and Defense Electronics sales, not its imaging business. Growth would indicate stronger customer spending in overlapping markets and support the demand backdrop for HEICO's Electronic Technologies components; a decline would suggest that demand may be softening. The takeaway is whether the market is providing a tailwind or headwind, not that HEICO's sales moved by the same amount.
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 component-repair business offers a close read on aviation customers' demand for repair work that HEICO also performs.
Watch the component-repair business StandardAero reports. Growth would suggest more repair activity among aviation customers, supporting the demand backdrop for HEICO's Flight Support repair and overhaul services; weakness would point to possible pressure on that work. The businesses are not identical, so the conclusion is the direction of repair demand among shared customer markets, not a substitute for HEICO's own results.
TransDigm Group Incorporated earningsTDG
TransDigm Group's aircraft replacement sales will show both demand and a competitor's activity in markets that overlap with HEICO.
Watch TransDigm Group's replacement sales of pumps, valves and power-control components. Growth would indicate firm customer demand in overlapping aircraft-parts markets, while also showing that a competitor is capturing sales; a decline would suggest a weaker market, not an automatic win for HEICO. The conclusion must separate shared demand from competitor performance rather than treat one company's sales as the other's result.
HEICO Corporation earningsThis company
HEICO's report will show whether sales growth in its aircraft-parts and repair business and its electronics business is still turning into profit.
Read sales growth alongside operating margin—the share of sales left after segment operating costs—for Flight Support and Electronic Technologies, and note how much growth came from acquisitions. Growth in both segments with steady or improving margins, not just acquired sales, would show that expansion is still producing profit. Growth driven mainly by acquisitions, or accompanied by narrower margins, would point to weaker underlying momentum or less profitable growth. The conclusion is whether HEICO can grow both businesses while protecting profitability.
