Bentley Systems (BSY) vs Roper Technologies (ROP)

2026-06-22 · By Lubin Danilo, founder of Lubin Investment

Bentley Systems and Roper Technologies both earn the top quality score in my fundamental screener. Bentley is a pure play on digital infrastructure engineering with strong organic growth. Roper is a serial acquirer of niche software whose strength lies in capital allocation discipline. Roper's valuation is significantly more attractive today.

• Bentley Systems (BSY) and Roper Technologies (ROP) both achieve the maximum quality score under my fundamental analysis criteria.
• BSY has a market cap of roughly $10 billion; ROP exceeds $33.5 billion, more than three times the size of BSY.
• The two models are opposites: BSY builds a single deep product for infrastructure engineering, ROP acquires dozens of vertical software businesses across varied niches.
• BSY trades at 22 times its annual free cash flow; ROP trades at 14.1 times, making it the cheaper option of the two at comparable quality.
• BSY suits an investor seeking exposure to infrastructure software growth and international markets; ROP suits a long-term value profile focused on disciplined capital allocation.

Two perfect software companies, two very different stories

When my screener assigns the maximum quality score to a company, it is rare. When two companies in the same sector achieve it simultaneously, it is even more unusual. Yet that is the case for Bentley Systems and Roper Technologies, both listed in the United States in the software applications category. But looking similar on a criteria sheet does not mean being similar in reality. The two businesses have fundamentally different models, sizes, growth rates, and risk profiles. This comparison exists to help you understand those differences, not to tell you which one to buy.

What these two companies have in common: they generate exceptional free cash flow margins, their revenues are highly recurring, their customers do not leave, and their management allocates capital with discipline. That is where the resemblance ends. The nature of the competitive moat, the geographic exposure, the growth engine, and the relative valuation diverge significantly.

Bentley Systems: the digital engineering of the physical world

Bentley Systems sells software to engineers who design and manage physical infrastructure: bridges, roads, water and energy networks, railways, ports, and industrial facilities. Concretely, when a design firm launches a major project in India, Germany, or Brazil, it very often opens a BSY product. The company serves 200,000 active engineers in 190 countries, and more than 75% of its revenues are recurring subscriptions. That translates into exceptional visibility on future revenues.

What makes BSY particularly defensible is the depth of integration into its customers' workflows. A design firm that has modeled a rail network over twenty years using BSY tools cannot simply migrate to a competitor in six months. Its files, internal standards, trained teams, and irreplaceable historical data: everything depends on the BSY ecosystem. The cost of switching is so high that it becomes a natural economic barrier, known as extreme switching costs.

Financially, BSY posts an 82% gross margin and a 26.8% free cash flow margin. Organic growth runs around 10% per year, driven by the accelerating digitization of infrastructure projects worldwide, particularly under the influence of public stimulus plans in the United States, Europe, and Asia. BSY benefits from a dual engine: growth from its existing customer base and the ramp-up of major global infrastructure projects.

Roper Technologies: the quiet serial acquirer

Roper Technologies has no single flagship product you could name in one sentence. It has a model. For more than twenty years, it has identified vertical software leaders in highly specific niches: insurance distribution management, hospital financial planning, tools for law firms, transportation logistics, and educational systems. It buys them at a disciplined price, holds them permanently, and reinvests the cash they generate into new acquisitions.

This model is called a serial acquirer. It does not rely on product innovation but on the quality of selection and execution. Each software acquired by Roper is the central nervous system of its market: customers have used it for years, their data is embedded in it, and migrating would require considerable resources at enormous operational risk. The result: very high retention rates, strong visibility on future revenues, and the ability to raise prices modestly each year.

Roper's strength lies in its capital allocation. CEO Neil Hunn has methodically divested Roper's physical industrial businesses (pumps, measurement instruments) to focus exclusively on recurring-revenue software. This repositioning has lightened the balance sheet and pushed margins higher. ROP's free cash flow margin now reaches 29.9%, and its cash ROCE ranks among the best in the entire listed market.

The numbers side by side

This table prompts a few important observations. First, ROP posts a slightly higher free cash flow margin than BSY (29.9% vs 26.8%), which is counterintuitive when comparing a pure infrastructure software player to an acquisition portfolio. Second, the valuation gap is significant: 22 times for BSY versus 14.1 times for ROP. ROP's discount partly reflects the market's perception of a less exciting conglomerate versus a pure SaaS play, and partly its more modest organic growth. Third, BSY offers far more diversified geographic exposure, making it a natural hedge on global infrastructure spending growth.

Two different investor profiles

BSY suits an investor seeking direct exposure to the megatrend of digitizing physical infrastructure worldwide. It is a bet on the acceleration of public and private spending on roads, water networks, energy, and rail, particularly in the emerging economies of Asia and Latin America. The organic growth is there, visible, driven by an addressable market that is still largely under-digitized. The 22 times FCF valuation reflects this growth premium. To accept that price, you must believe BSY maintains its technological lead and dominant position in its niche over the next five to ten years.

ROP suits an investor from the value and quality school, attuned to the concept of compounding: the long-term accumulation of value through disciplined cash reinvestment. The 14.1 times FCF valuation is low for the quality of the underlying assets. This profile accepts modest organic growth in exchange for high predictability and management whose capital allocation track record spans more than twenty years. It is a quietly confident investment, not a momentum play.

There is also a size dimension to consider. BSY, at roughly $10 billion in market cap, still has room to grow significantly. Expansion into Africa or Southeast Asia, contracts with new large public clients, an acceleration toward digital twins of assets in operation: all of this represents potential additional growth catalysts. ROP, at $33.5 billion, is already a large cap; its growth will more likely come from margin improvement and acquisition quality than from a spectacular re-rating.

My conclusion without picking a side

I am not going to tell you which one to buy. That is not the role of this analysis, and it would be intellectually dishonest because it depends on your situation, your time horizon, your risk tolerance, and what you already hold in your portfolio. What I can say is that these two companies represent two very different ways of accessing exceptional quality software at valuations that are reasonable for their category.

If you are looking for organic growth, international exposure, and a moat built on product uniqueness, BSY is the answer. If you are looking for relative undervaluation, maximum cash predictability, and a capital allocation model proven over two decades, ROP is the answer. Both deserve a place on your watchlist. Both earn the top score in my screener. And the fact that you have to choose between them is, in itself, a good problem to have.

FAQ

What is a serial acquirer in the stock market?

A serial acquirer is a company whose growth model relies on regularly acquiring other businesses. It generates cash from its existing operations, then reinvests it in targeted buyouts rather than in dividends or share repurchases. Roper Technologies has done this for more than twenty years, exclusively in specialized software focused on very specific niches.

What is the fundamental difference between BSY and ROP?

Bentley Systems builds a single, deeply specialized infrastructure engineering software platform, serving 200,000 engineers across 190 countries, with organic growth of around 10% per year. Roper Technologies manages a portfolio of dozens of vertical software products across varied sectors and grows primarily through disciplined acquisitions. BSY bets on product uniqueness; ROP bets on selection quality and capital allocation.

Which of the two is cheaper today?

Roper Technologies trades at 14.1 times its annual free cash flow, versus 22 times for Bentley Systems. ROP is therefore meaningfully cheaper at comparable quality. This discount reflects more modest organic growth and a conglomerate perception that the market has not yet fully corrected.

What are the specific risks for each company?

For BSY: dependence on public infrastructure investment cycles, and competitive pressure from Autodesk and Hexagon on adjacent segments. For ROP: the risk that the acquisition pipeline dries up or that management overpays for an important target. ROP's organic growth alone is not sufficient to justify its valuation if acquisitions were to stop.
