Pricing power: how the best stocks protect their profit margins

2026-06-24 · By Lubin Danilo, founder of Lubin Investment

Pricing power is a company's ability to raise prices without losing customers. When this power is real and lasting, it mechanically translates into growing free cash flow, year after year, without extra effort. It's the criterion that separates elite businesses from average ones, and the first thing I examine in my analysis method.

Key takeaway: pricing power is a company's ability to raise prices without losing customers. When structural, it produces free cash flow that grows consistently over time. ASML, CME Group, Verisign and Doximity are prime examples. This article explains the mechanism, how to measure it, and when it disappears.

The direct link between pricing freedom and durable free cash flow

A company that raises prices by 5% per year, with costs that don't rise proportionally, sees almost all of that price increase flow straight into free cash flow. This operating leverage is the engine of compounding returns. The opposite is equally true: forced price cuts erode FCF faster than revenue. ASML (monopoly on EUV lithography), CME Group (mandatory clearing), Verisign (ICANN-mandated .com registry) and Doximity (80% physician network) all demonstrate this in their financials: stable or growing FCF margins of 25-55%, Cash ROCE well above their cost of capital.

How I measure pricing power in four indicators

I look at: (1) five-year FCF margin trend, (2) margin stability and growth, (3) customer retention above 90%, (4) Cash ROCE. A declining FCF margin despite price increases means costs are rising just as fast. That is the first warning sign that pricing power is eroding. For more on how I interpret these metrics by sector, see my article on <a href="/blog/pfcf-sectoriel-saas-assurance-interpretation-ratio">sector-specific FCF ratios</a>.

Three threats that destroy pricing power

Technological disruption (a better product makes yours redundant), regulation (price caps or forced market opening), and commoditization (the product becomes generic). A pricing power that won't survive ten years is worth far less than one that will. Explore any company's pricing power metrics in <a href="/analyser">the full screener</a>.

FAQ

What is a company's pricing power?

The ability to raise prices without losing customers, giving the company control over its own profitability regardless of competition or the economy.

How does pricing power translate to free cash flow?

Directly and mechanically: price increases flow into FCF when costs are fixed. Operating leverage amplifies revenue gains into much larger cash gains.

How do I know if pricing power is real?

Stable or growing FCF margin over five years, customer retention above 90%, real price growth documented over years, and a high Cash ROCE.

Can pricing power disappear?

Yes: tech disruption, regulation, and commoditization are the three main threats. Always evaluate whether today's pricing power will still exist in ten years.

Is a high valuation justified?

It can be if pricing power is durable. A 30-35x FCF multiple is reasonable if FCF grows 10-15% annually for a decade. This is not investment advice.
