Bentley Systems (BSY): infrastructure software monopoly
2026-06-22 · By Lubin Danilo, founder of Lubin Investment
Bentley Systems is the only software platform in the world built exclusively for the design and management of physical infrastructure. With 200,000 active engineers across 190 countries, recurring revenues above 75% and an 82% gross margin, it is one of the most discreet cash machines in tech. Its valuation is high, but justified by a rare quality profile.
- Unique moat: no global competitor covers the full spectrum of physical infrastructure (bridges, roads, water networks, energy, plants) the way BSY does.
- Recurring revenues above 75% thanks to the SaaS model; engineers stay for decades because their data lives inside BSY systems.
- 82% gross margin and solid, growing free cash flow: elite-level profitability rare in any sector.
- Perfect quality score in my screener (10/10): all financial criteria in the green, rising sales and cash, controlled debt.
- Valuation at 24 times free cash flow: a premium justified by revenue visibility, extreme switching costs and the absence of a direct global competitor.
What Bentley Systems actually does
When we talk about software, we usually think of Salesforce or Microsoft. Bentley Systems is something else entirely: it is the software engineers use to design a bridge in India, model a drinking water network in Australia, or manage the maintenance of a power plant in Germany. Concretely, BSY sells CAD tools (computer-aided design) and infrastructure digital twins, meaning virtual replicas of real-world assets used throughout the entire lifecycle of a project.
What I appreciate about this model is its discretion. Bentley does not appear in mainstream conversations the way NVIDIA or Apple does. Yet whenever a major infrastructure project starts somewhere in the world, engineers very often open a BSY product. That is a position of strength markets sometimes forget to price in correctly.
The moat: why engineers cannot leave
A moat is a company's competitive advantage, the barrier that keeps competitors at bay over time. For Bentley, it is built on what is called switching cost, literally the cost of changing tools. Imagine a team of engineers that has modeled an entire rail network inside BSY tools over twenty years: thousands of files, internal standards, entire workflows calibrated to these products. Migrating elsewhere would not take six months, it would take years, and risking the loss of irreplaceable data. The result: once an engineering firm enters the BSY ecosystem, it rarely leaves.
This extreme switching cost shows up directly in the numbers: over 75% of BSY revenues are recurring subscriptions. That means at the start of each year, the company already knows where more than three-quarters of its sales will come from. That is exceptional visibility, something very few companies can claim.
Financial quality: what the numbers say
When I analyze a stock, I always start with business quality before talking about price. My method relies on objective financial criteria: does the company generate cash, are its margins high, does it buy back its own shares rather than diluting shareholders, is its debt under control? At BSY, almost all of these boxes are checked.
The gross margin stands at 82%. Gross margin is what remains after paying the direct costs of producing and delivering the software. A margin of 82% means that for every 100 dollars in revenue, 82 are available to pay staff, invest in R&D and generate profit. That is elite-level, comparable to the best software publishers in the world. Free cash flow, meaning the money that actually lands in the bank once all bills are paid, is solid and growing. BSY also beat estimates in Q1 2026, a sign that business momentum remains intact.
A valuation at 24 times FCF: expensive or justified?
This is the heart of the debate around BSY. Valuation is what the market is willing to pay for one dollar of the company's free cash flow. The P/FCF ratio (price-to-free-cash-flow) is the stock price divided by the annual free cash flow per share. A P/FCF of 24 means you are paying today for twenty-four years of that cash. That is indeed a high valuation.
But a high valuation is not automatically bad. It becomes unjustified when growth slows, the moat erodes, or revenue visibility drops. Here, the opposite is true: revenues are ultra-recurring, customers do not leave, and there is no global competitor in this precise niche. For comparison, ServiceNow, which also offers SaaS software with strong switching costs, trades at 44 times FCF. Shopify exceeds 85 times. At 24 times, BSY trades at a discount to peers of comparable quality, with revenue visibility that I would argue is even stronger.
| Company | Ticker | Approx. P/FCF | Recurring revenues | Key moat |
|---|---|---|---|---|
| Bentley Systems | BSY | 24× | >75% | Infra niche, decade-long switching cost |
| Roper Technologies | ROP | ~35× | >80% | SaaS portfolio across industrial niches |
| Autodesk | ADSK | ~30× | >90% | Generalist CAD, large installed base |
| Hexagon AB | HEXA B | ~22× | ~60% | Industrial measurement and sensors |
This table helps position BSY within its universe. Autodesk is the most frequently cited competitor, but it is a generalist: it serves architects, product designers and filmmakers. BSY is a specialist: it serves only physical infrastructure engineers. This specialization creates a depth of functionality that Autodesk cannot easily replicate, and partly explains the extreme loyalty of its customers.
Risks you should not ignore
I will be honest: BSY is not without risks. Here are the three I watch most closely. The first is the dependence on large public infrastructure investment cycles. When governments cut capital expenditure budgets, BSY feels the impact with a lag of a few quarters. We saw this during budget contraction cycles in Europe and North America.
The second risk is niche competition. Autodesk and Hexagon, though positioned differently, are both trying to chip away at adjacent segments. Hexagon in particular is investing heavily in industrial digital twins, a territory BSY considers its own. It is not a head-on war, but a constant pressure on certain product segments.
The third risk is customer concentration. Large infrastructure projects often involve a small number of very large clients. If one of them goes through a crisis or delays a major project, the revenue impact can show up within a quarter. It is not a dealbreaker, but it requires ongoing attention to client portfolio diversification.
What my screener says about BSY
My analysis method assigns a quality score out of 10 to every company I study. This score does not judge the stock price, it judges only the solidity of the business: are revenues and cash growing consistently, are margins stable or improving, does the company generate a high return on the capital it deploys, does it buy back its own shares to reward shareholders without sacrificing growth? Bentley Systems scores 10/10 in my screener. That is not a frequent score. It reflects a combination of consistent growth, elite margins, a recurring business model and well-allocated capital. The quality is there. What remains to watch is the right entry price.
At 24 times FCF and a market cap of around 15 billion dollars, BSY is not cheap. But for a company with this level of revenue visibility, this moat and these margins, I consider the premium justified. That does not mean I buy it blindly: I have a target price, and I wait for it to come to me. This is exactly the kind of analysis I wanted to run quickly on any stock, which is why I built my screener at lubin-investment.com.
FAQ
What is free cash flow and why does it matter?
Free cash flow is the money that actually stays in the company's bank after paying all operating bills and investments. It is harder to manipulate than accounting profit, so I trust it more when assessing a company's true financial health.
Why does Bentley Systems have so few direct competitors?
Because the software market for physical infrastructure engineering is a highly technical niche with long sales cycles and very specific regulatory requirements that vary by country. BSY has invested for thirty years to cover this niche in its entirety, something no generalist player has managed to replicate.
Is a valuation at 24 times FCF expensive?
It is indeed a high valuation. But it compares favorably to peers like ServiceNow (44 times) or Shopify (85 times). The premium is justified by revenue recurrence, extreme switching costs and the absence of a direct global competitor. A high valuation is only unjustified when the underlying business quality does not support it.
What are the main risks for BSY stock?
Dependence on public infrastructure investment cycles, competitive pressure from Autodesk and Hexagon on adjacent segments, and the concentration of certain large clients. These risks are real but do not undermine the company's fundamental moat.
How does Bentley Systems make money in practice?
Primarily through annual or multi-year subscriptions sold to engineering firms, public project owners and industrial companies across 190 countries. More than 75% of revenues are recurring, meaning the majority of sales are already contracted before each fiscal year begins.
