HEICO Corporation
HEI
May 30, 2026
HEICO Corporation (NYSE: HEI / HEI.A) is the world's largest independent manufacturer of FAA-approved aircraft replacement parts (PMA) and a leading sub-tier supplier of niche defense electronics, headquartered in Hollywood, Florida and family-controlled by the Mendelson family since 1990. The Flight Support Group (FSG, ~65% of revenue) reverse-engineers OEM aircraft parts, secures FAA PMA certification, and sells those parts to airlines and MROs at a 30–40% discount to OEM. The Electronic Technologies Group (ETG, ~35%) makes specialized defense, medical, and industrial electronics. FY2024 revenue was ~$3.87B with 22.5% EBIT margins and ~$675M FCF.
▲ Bull Case
- ◆Wencor synergies + secular MRO tailwind drive FY2026 EBIT margins toward 24%, pushing EPS toward $6.30 vs. consensus $5.50–6.00; multiple holds at 45–50x as quality-compounder scarcity premium persists
- ◆ETG defense electronics outperforms 18%+ growth through FY2027 as NATO procurement programs ramp, with new sole-source designs locking in 15–25 year program revenue streams
- ◆Disciplined M&A engine re-engages at scale by FY2026 as Net Debt/EBITDA approaches <2x, enabling 4–6 bolt-on deals/year at HEICO's historical 8–12x EBITDA multiples — sustaining 15%+ EPS CAGR through the decade
▼ Bear Case
- ◆Valuation creates asymmetric risk: at 42–48x forward P/E with limited margin of safety, any 100–200bps EPS growth disappointment produces 20–30% multiple compression for premium compounders
- ◆OEM long-term service agreements structurally compress PMA TAM: if major US carriers shift 30–40% of fleet maintenance to OEM-exclusive LTSAs by 2028, FSG addressable market shrinks permanently
- ◆Succession concentration risk: Larry Mendelson is 83 with deal-sourcing relationships not fully transferable; negative succession event combined with weak earnings could trigger 25–35% drawdown
“The debate is not whether HEICO is high-quality — that is consensus. The debate is whether the premium multiple (42–48x forward P/E) is sustainable given: (1) post-Wencor margin expansion thesis (20.9% → 23–24%), (2) LTSA penetration as dormant secular headwind, (3) ETG defense tailwind sustainability, and (4) family succession plan de-risking. Sell-side is broadly Buy-rated (12 of 18) with average PT of $365.58 implying ~14% upside. The minority bear view focuses entirely on valuation, not business quality.”
- ◆FSG operating margin tracking >22% in FY2025 quarterly prints validates Wencor synergy thesis
- ◆Net Debt/EBITDA reaches <2.0x by FY2026 Q2 frees M&A engine and removes refinancing overhang
- ◆ETG quarterly revenue growth >18% sustained through FY2026 validates defense electronics tailwind
- ◆New large M&A deal announcement (>$300M target) signals balance sheet healed and deal pipeline alive
- ◆Quarterly earnings beat (HEICO has beaten in >90% of quarters for a decade)
- ◆Air-travel demand shock (recession, pandemic, geopolitical) pressures FSG revenue
- ◆OEM LTSA acceleration (major US carrier announces fleet-wide OEM-exclusive maintenance contract) signals secular TAM compression
- ◆Wencor synergy disappointment — FSG margins stuck at 20–21% invalidates bull thesis margin assumption
- ◆Mendelson family succession event — Larry is 83; unexpected disruption is market-moving
- ◆Interest-rate-driven multiple compression — premium compounders are duration-sensitive; sustained higher rates compress 40x+ multiples
- ◆PMA safety incident — low probability but high consequence; could trigger regulatory scrutiny and customer pullback
