In the Quality Compounder Hub, I lay out the characteristics I look for when evaluating long-term investments. Things like durable moats, high returns on invested capital, pricing power, and disciplined capital allocation form the foundation.
But criteria are just theory until you see them applied.
One of the most common questions I get is a practical one: What does a quality compounder actually look like in practice?
That is the purpose of this article.
To do this I will break that question down using four real-world examples. Each example will illustrate a different way that high-quality businesses create long-term value. These are companies that operate in very different industries and wildly different parts of the economy, but they share similar DNA. Each benefits from durable demand, reinvests capital at attractive rates, and business models that create economic value.
Mastercard (MA)
Let’s start with the purest example of a high-return, capital-light business.
Mastercard operates one of the largest payment networks in the world, processing billions of transactions every day. Every time someone taps a card or books something online that travels across its rails, Mastercard collects a small fee.
It really is a wonderful business. Mastercard does not lend money or take credit risk. The business is simpler. Its role is to connect consumers, merchants, and banks via its network, and to make sure payments move quickly and securely. And like S&P Global, Mastercard is a capital-light business built on intangible assets.
How the Business Compounds
Mastercard benefits from powerful network effects. Its acceptance at more than 130 million merchant locations makes the network indispensable. Merchants have to accept the cards because so many customers have them. And customers want to carry the cards because they are accepted everywhere. Once a network reaches this size, it becomes extremely difficult to displace.
Just as important, once the network is built, processing more transactions costs very little. As a greater percentage of spending is digitized and as prices rise over time, revenue rises much faster than expenses, creating operating leverage.
And since Mastercard’s core business requires little capital to grow, it is able to return nearly 100% of free cash flow to shareholders. In 2024 alone, they returned nearly $12 billion through dividends and share repurchases.
Mastercard reinvestment dollars go toward expanding the network through a series of value added services (VAS). These include fraud protection, cybersecurity tools, tokenization, and data analytics. These services sit on top of existing relationships which increases revenue per transaction.
Compounding Evidence
- Net revenue has grown at a around 11% CAGR since 2019.
- Adjusted operating margins consistently approach 60%.
- Returns on Invested Capital consistently exceed 40-50%, demonstrating the efficiency of their capital deployment.
- Aggressive buybacks combined with organic growth have driven double-digit growth in free cash flow per share.
Mastercard is the ultimate consumer toll road business. But what happens when we apply that same toll road model to the complex world of Wall Street? You get S&P Global.
2. S&P Global (SPGI)
S&P Global provides the credit ratings, benchmarks, and data analytics that serve the global financial markets. If a company wants to issue debt, they generally need a rating. If a fund wants to benchmark performance, they pay S&P for the index data. That positioning creates an unusually strong economic foundation.
How the Business Compounds
Like Mastercard, S&P benefits from a market structure with limited competition. Growth in its Rating and Indices segments is driven by rising debt issuance over time, higher assets under management as markets grow, and the continued shift toward passive investing. None of this requires meaningful incremental capital.
S&P also adds a layer of proprietary data. Through acquisitions like IHS Markit, S&P has put together datasets of reliable and trusted data for markets. This data can be repackaged and resold across different segments. Doing so lowers the cost of innovation for S&P, and creates a sticky ecosystem where customers cannot easily leave.
These dynamics drive margin expansion as operating leverage plays out. And the capital light nature of the business allows a large share of free cash flow to be returned to shareholders through dividends and buybacks, creating an EPS compounding effect.
Compounding Evidence
- Revenue has more than doubled since 2019, supported by the IHS Markit merger and continued organic growth.
- Adjusted operating margins consistently sit around 50%, reflecting the beauty of selling data.
- The company has increased the dividend for 52 consecutive years and reduced shares outstanding by nearly 5% annually.
- By training AI on their proprietary data, they are creating new moats that competitors without historical data cannot replicate.
Both Mastercard and S&P Global are capital-light, meaning they grow without needing heavy investment. But not all compounders are light. Some require heavy investment, but they are so good at deploying that capital that they distance themselves from the pack. That brings us to Thermo Fisher.
Thermo Fisher Scientific (TMO)
Thermo Fisher sells the instruments that laboratories around the world depend on. More than 80% of their revenue comes from recurring consumables and services revenue. The way this works is Thermo sells the instruments which require consumables and add on the services to support customers.
How the Business Compounds
Unlike the previous two examples, the real story for Thermo is their acquisition strategy. The life sciences industry is fragmented. Thermo is working as a consolidator to bring an end-to-end solution for scientific research and drug development under one roof. Since 2019, management has deployed more than $50 billion into strategic acquisitions, including transformative deals like PPD and more targeted additions such as Olink and Solventum’s filtration business.
While large acquisitions often introduce complexity that erodes returns, Thermo has largely avoided that outcome. The company uses its PPI Business System to integrate acquisitions, strip out costs, and expand the margins of the companies it buys.
That strategy has produced both scale and switching costs. By offering everything from early-stage research tools to commercial drug manufacturing, Thermo becomes deeply integrated into customer workflows. Once a customer is locked into the ecosystem, switching becomes costly and risky.
Compounding Evidence
- Revenue has grown at roughly an 11% CAGR, expanding from approximately $25 billion to over $40 billion.
- Free cash flow per share has grown at a double-digit rate over the past five years, reflecting organic growth, M&A, and capital discipline.
- Despite heavy M&A, returns on invested capital, including goodwill, have remained above the cost of capital.
- Adjusted operating margins have stabilized and expanded post-pandemic, now sitting around 23%.
Thermo Fisher strategy is more complex and demanding than the others discussed thus far. But we can argue that this is also why it has created so much distance from competitors.
Cintas (CTAS)
Cintas provides uniform rentals, floor mats, facility services, and safety products to over one million businesses across North America. This is probably least familiar name on this list. But this is just one of those under the radar companies that executes very well.
How the Business Compounds
Unlike the S&P and Mastercard, Cintas is not asset-light. It owns fleets of trucks and massive laundry facilities. However, it generates asset-light returns because of route density and cross-selling.
Cintas is dependent on maximizing the efficiency of their existing infrastructure. Its trucks run fixed routes, servicing the same customers week after week. So if a truck is able to hit ten stops on one street instead of one, revenue rises, while costs remain the same. This is what operating leverage looks like for Cintas.
With more than 12,000 routes in operation, route density is a core advantage. Cintas can underprice smaller competitors while still earning higher margins. And once Cintas is handling those functions, switching to local competitors offers little benefit.
In the meantime, Cintas can cross sell, and they do. Cintas service professionals typically develop close relationships with clients they see on a regular basis, finding pain points and offering high margin solutions like first aid kits, fire extinguisher checks, and restroom supplies. This raises revenue per stop and deepens customer relationships.
Management reinvests this cash into systems like “SmartTruck” to further optimize routes and into acquiring local players to plug into their logistics network. Whatever is left is returned to shareholders.
Compounding Evidence
- Revenue has grown at high single-digit rates across cycles, with organic growth remaining strong even in slower environments.
- Operating margins have steadily increased as route density and efficiency improve, reaching nearly 23% in FY2025.
- The combination of steady revenue growth, expanding margins, and ongoing share repurchases has produced double-digit free cash flow per share.
This is not compounding driven by innovation, but by pure efficiency.
Final Thoughts
Long-term compounding can happen in a number of ways. When we look at these four side-by-side, we can see that. Mastercard compounds through network effects. S&P Global compounds through embedded standards and proprietary data. Thermo Fisher compounds through scale and a disciplined acquisition strategy. Cintas compounds through route density and efficiency.
While they take different paths, they all have the ability to reinvest capital at high rates of return for long periods of time.
This is the difference between a trading stock and a foundational holding. These companies do not rely on heroic assumptions, lucky timing or commodity price spikes. Instead, they rely on business models designed to do well over the long term.
And over that long time horizon, that consistency creates an inevitability while providing investors the conviction to allow compounding to do its job.
