Background and Overview

History and Founding: HEICO was founded in 1957 as Heinicke Instrument Corp., initially focusing on laboratory equipment. It entered the aerospace market in the 1970s through the acquisition of Jet Avion, a pioneer in the PMA industry. The Mendelson family, led by Larry Mendelson (Chairman and CEO) and his sons Eric and Victor (presidents of the two main segments), took control in 1990 after acquiring a 15% stake for $3 million and ousting the existing management through a proxy battle. Since then, HEICO has transformed into a leading aerospace and defense supplier, with sales compounding at 15% annually, net income at 18%, and shareholder returns at 21% annually from 1990 to 2024.

Context and Operations: HEICO operates in two primary segments:

• Flight Support Group (FSG): Focuses on commercial aerospace, providing PMA parts, repair and overhaul services, and distribution of aircraft parts. This segment represents approximately 66% of revenue.
• Electronic Technologies Group (ETG): Supplies mission-critical components for defense, space, and niche technology applications, contributing about 33% of revenue but 40% of operating profit due to higher margins.

Category and Scale: HEICO is a compounder with a decentralized operating model, employing approximately 9,600 full-time equivalents (FTEs) as of recent estimates. It serves a global customer base, with a strong presence in the U.S. and exposure to international markets through airline and defense contracts. The company’s manufacturing and service facilities are strategically located to support its supply chain and customer proximity.

Key Milestone: A pivotal moment was Lufthansa’s 1997 investment in a 20% stake in HEICO’s PMA business (initially $25 million, later increased to $50 million). This partnership provided capital, technical data, and an anchor customer, accelerating PMA development and establishing HEICO as the market leader.

Ownership and Recent Valuation

Ownership: The Mendelson family owns approximately 8% of HEICO’s equity, with the board holding an additional 2.5%. Employees own over 2% through a 401(k) plan, which includes annual stock grants equivalent to 5% of their compensation. This ownership structure fosters alignment across management, employees, and shareholders. Lufthansa retains a 20% stake in the PMA business, though its value is difficult to quantify due to subsequent acquisitions and restructuring.

Recent Transactions: HEICO’s largest acquisition was Wencor in 2023, a $2 billion deal that added 7,000 PMA parts to its portfolio, enhancing its scale and market dominance. Historically, HEICO has deployed over $5 billion on 98 acquisitions since 1990, with minimal restructuring charges (less than $10 million). Acquisitions are typically executed at mid- to high-single-digit cash multiples, targeting businesses with high-teen to 20% margins.

Valuation: As of April 2025, HEICO’s market capitalization is not explicitly stated in the transcript, but its revenue base of $3.8 billion (pro forma for Wencor) and historical performance suggest a premium valuation. Comparable aerospace and defense firms, such as TransDigm, often trade at 15-20x EV/EBITDA. Assuming HEICO’s EBITDA margins of ~22-25% and a similar multiple range, its enterprise value (EV) could approximate $10-12 billion, though this is an estimate and subject to market conditions.
