The AMETEK Formula

Continually grow by focusing on understanding and satisfying the needs of your customers. If you really put that at the top of your pyramid, everything else will fall into place.

One of the original eight

When Mark Leonard was building Constellation Software, he studied eight “High Performing Conglomerates” to understand what made serial acquirers work. AMETEK was one of them.

The company has compounded from roughly $700 million to $48 billion in market cap over 25 years — an 18% annual return sustained across two CEOs and dozens of acquisitions. The playbook that produced these returns influenced how Leonard thought about his own.

AMETEK makes electronic instruments and electromechanical devices. The products serve aerospace, defence, medical, and industrial markets. Most are mission-critical, high-precision, and embedded deeply enough in customer operations that switching costs are substantial.

Four growth strategies

Frank Hermance, who ran AMETEK from 1999 to 2016, codified the operating model into four pillars:

Operational excellence. Kaizen, lean manufacturing, global sourcing, value engineering. The tools are standard; the discipline in applying them is not.

New product development. AMETEK tracks a “Vitality Index” — the percentage of sales from products introduced in the last three years. The target is 25%. They consistently hit it.

Global and market expansion. Operations in 30 countries, 150+ manufacturing sites. The geographic spread creates both growth opportunities and natural hedges.

Strategic acquisitions. Disciplined M&A with explicit return hurdles. Target: 10% ROIC within three years of closing.

The framework sounds generic. The execution is not. AMETEK has made 60-80 acquisitions over two decades without a major stumble.

The quiet compounder

AMETEK doesn’t seek attention. There are no famous shareholder letters, no high-profile founder mythology, no controversial pricing practices. The company compounds in relative obscurity.

David Zapico, who succeeded Hermance in 2016: “I’ve been with AMETEK for 35 years. I’ve been CEO for 9 years. And over those 9 years, we’ve averaged 4% organic growth. When you have 4% organic growth, double-digit on the top line, double-digit orders, double-digit earnings — that’s the model.”

The consistency is the point. No dramatic pivots, no transformational acquisitions, no strategic reinventions. Just four growth strategies applied methodically for decades.

Niche dominance

Like most successful serial acquirers, AMETEK focuses on market leadership in small segments. The goal: #1 or #2 positions in specialised niches where scale advantages accrue to the leader and switching costs protect margins.

The businesses are often invisible to consumers — pressure sensors for aircraft, analytical instruments for laboratories, precision motors for medical devices. The markets are too small for large competitors to prioritise. The applications are too critical for customers to risk switching.

Morningstar upgraded AMETEK to “Wide Moat” status in 2024. The reasoning: high switching costs from deeply embedded products, plus intangible assets from decades of accumulated expertise in specialised applications.

What Hermance built

The track record under Hermance: sales from $925 million to $4 billion, EPS compounding at 15% annually, stock price up 1,500%. Zapico has continued the formula — operating margins now exceed 26%, a company record.

AMETEK won’t produce the quotable insights of a Constellation or the controversy of a TransDigm. The philosophy is execution, not innovation. Four growth strategies, applied consistently, for a quarter century.

Sometimes the pattern is the insight.
