SOCOTEC Acquisitions: What It Buys and What It Pays

SOCOTEC, a French group majority-owned by the Belgian investment company Cobepa, has made 79 acquisitions of testing, inspection and certification (TIC) firms since 2015. Most were small firms that inspect and test buildings, ground and infrastructure. SOCOTEC publishes no prices, but the filed accounts of its UK companies put eight UK purchases at an average of about $19M. In our TIC valuation research, deals under $50M sold at a median 8.0x EBITDA (21 deals with a published multiple). Deals of $500M and over, the size of SOCOTEC itself, sold at 12.2x (11 deals). A small firm’s profit is worth that higher multiple to SOCOTEC’s owners once it sits inside the group.

SOCOTEC can pay part of the price after closing, as earn-outs that depend on the firm’s results or as later payments for shares the seller keeps. If you sell, you earn that later part while your firm is run inside SOCOTEC’s company in your country.

SOCOTEC Subsidiaries and Ownership

Cobepa has held the majority since 2013. The minority owners are the private equity firm Clayton Dubilier & Rice (since December 2019), the French public investment bank Bpifrance and the Abu Dhabi investor Mubadala (both since May 2024), and the group’s own managers. None of them publishes its stake.

The group had $2.0bn of revenue in 2025, with about 14,800 employees in 26 countries. France, where it started, still brings in about two fifths of that revenue. Outside France its main national companies are in six countries: the United States, the United Kingdom, Germany, Italy, the Netherlands and Spain. Each carries the SOCOTEC name, as in SOCOTEC UK or SOCOTEC Italia. A firm SOCOTEC buys joins the SOCOTEC company in the firm’s country. That company is the one you would deal with.

How Many Companies SOCOTEC Acquires

We count 79 acquisitions since 2015. In building and infrastructure testing firms, SOCOTEC is the most active buyer in our data, well ahead of the next, Phenna. Its buying sped up in 2023 to 2025, with 38 deals in those three years, about 13 a year, against 37 in the eight years before.

The median firm SOCOTEC bought had about $14M of revenue, across the 23 purchases whose announcement gave a figure. By headcount, the firms it bought ranged from four people to about 1,400, and most had between 30 and 150.

What SOCOTEC Buys and Where

Most of the firms SOCOTEC buys serve construction and infrastructure. They monitor bridges and tunnels, check buildings against fire codes, test materials or investigate the ground before building starts.

Building compliance covers building control, code and fire consulting, advice on the building envelope (its outer walls and roof), and asbestos and energy surveys. If you run one of these trades, our valuation pages show what such firms sell for: building inspection, geotechnical engineering, construction materials testing and special inspection, environmental consultancy, health and safety consultancy, industrial inspection and non-destructive testing and training companies.

All but one of SOCOTEC’s purchases were in the seven countries where it runs its main national companies. The exception was a small firm in Morocco, bought by SOCOTEC’s company there.

Its buying has grown most in the United States. Up to 2022, 6 of its 37 deals were American. Since 2023, 11 of 42 have been.

In the UK, Italy and the US, the first firm SOCOTEC bought since 2015 became its company in that country, and later purchases there, large and small, joined it.

What SOCOTEC Pays: Acquisition Multiples

Buyers value a firm as a multiple of its EBITDA, which is earnings before interest, tax, depreciation and amortization, adjusted for one-off costs and the owner’s own pay. At 8x, a firm with $2M of EBITDA is worth $16M. That figure is its enterprise value (EV), the value of the whole business, from which any debt is repaid and the owner keeps the rest.

SOCOTEC buys mostly small firms, and the only prices on record are in the filed accounts of its UK companies. They put eight UK purchases from 2021 to 2025 at $150M in all, counting payments due later and deal costs. That is about $19M each on average, which falls in the smallest size band of our TIC research, deals under $50M.

A firm bought at around 8x, the median for deals under $50M, joins a group that would itself sell at around 12x, the multiple for deals of SOCOTEC’s size. Take a firm with $2M of EBITDA. Bought at 8x it costs $16M. Inside a group sold at 12x, the same profit is worth about $24M, $8M more than it cost. Investors who own a group like SOCOTEC buy small firms for that reason. When several buyers compete for the same firm, the seller can take part of that difference as a higher price.

How SOCOTEC Structures a Deal

SOCOTEC can pay part of the price later, in two ways. Moody’s counted both in the group’s debt when it rated SOCOTEC in April 2021. Earn-outs depend on the firm’s results after the sale. Put-and-call obligations are agreements to buy, at a later date, shares a seller kept. A put lets the seller require the buyer to take those shares, and a call lets the buyer require the seller to sell them.

SOCOTEC UK’s accounts for 2025, filed at Companies House, say its investments “include an estimate for future earn outs and deferred considerations on recent acquisitions”. At the end of 2025 it owed $36.9M of deferred consideration for its purchases, against $11.5M a year earlier. Of that, $31.7M falls due after more than a year.

How much is paid at closing, and on what conditions the rest follows, is agreed deal by deal and kept private. By the time a later payment falls due, your firm may already carry the SOCOTEC name and work to group processes, and the results the payment depends on are then produced inside SOCOTEC.

What Happens After Closing

Wherever SOCOTEC has said what became of a firm it bought, the firm took the SOCOTEC name or was folded into a SOCOTEC company. Its first UK and Italian purchases were renamed within about seven months. Its first US purchase kept its name for about two and a half years. Several firms kept their own names for a time before being folded in.

Founders stay or go case by case. A minority of SOCOTEC’s announcements name a founder staying in a role. UK company records show some founders staying on as directors while others left at closing. Over time the group aims to need them less. Its 2025 sustainability report, dated April 2026, describes the gradual integration of acquired teams into group processes, “allowing for a progressive reduction in dependence on their initial management team while preserving and valuing their specific local expertise”.

If you stay, you may be able to own part of the group. A quarter of SOCOTEC’s employees were shareholders at the end of 2025, and more than 400 managers were invited to invest when Bpifrance and Mubadala joined in 2024.

SOCOTEC Competitors: Who Else Buys Firms Like Yours

Which groups would compete with SOCOTEC for your firm depends on your country.

In the UK, Phenna, Celnor and RSK buy the same kinds of firm. The US field is wider: Universal Engineering Sciences, Certerra, Terracon and SAFEbuilt. In France the main other buyer is Ginger CEBTP. No other group there has bought more than three such firms. Bureau Veritas and Kiwa buy such firms in many countries, SOCOTEC’s among them. In Germany, Italy and Spain no other group in our data has bought more than two building and infrastructure firms.

SOCOTEC has negotiated 79 purchases since 2015. An owner who answers its approach alone sells at its price and on its terms, including the share paid at closing. We run a competitive process among the TIC groups, private equity platforms and other buyers with a real reason to want your firm, so that you choose between the best offers and get the best price. The amount paid at closing then becomes a term buyers bid on, beside the price.

Is This a Good Time to Sell to SOCOTEC?

SOCOTEC keeps buying. It reports that 15.6 percentage points of its 20.1% revenue growth in 2025 were external, meaning acquisitions. Its plan to take revenue from about $2.0bn in 2025 to about $2.7bn in 2028 relies on buying more firms. That makes it a willing buyer today. The open question is who will own SOCOTEC when your later payments fall due.

Cobepa, its majority owner, is considering a sale of its stake, according to the Belgian newspaper De Tijd, as cited by an M&A news service on 15 October 2026. If a sale goes ahead, earn-outs and other payments due after closing, and the purchase of any shares a seller keeps, could fall due under a new owner of the group. The obligations stay with the SOCOTEC company that bought the firm, and that company would then answer to the new owner.

Methodology

The count covers majority acquisitions of TIC firms by SOCOTEC or a SOCOTEC company from 2015 to 14 November 2026, each checked against SOCOTEC’s own announcement or annual sustainability report or, failing that, the trade press. The deals come from the Aventis Advisors TIC deal database, built from Mergermarket and public sources such as acquirer announcements, news and annual reports. In three of the 79 deals SOCOTEC bought two companies together, and each counts as one deal. Some 2026 purchases are not yet in our data, so the 2026 figure is incomplete. The trades are our coding of SOCOTEC’s announcements.

Group revenue, growth, the 2028 target, revenue by country and staff ownership come from SOCOTEC’s 2025 sustainability report. UK purchase prices and deferred consideration come from the accounts of SOCOTEC UK Ltd and SOCOTEC Building & Real Estate Holdings Ltd, filed at UK Companies House. The prices are the cash and accrued deferred consideration they report, including costs, for eight purchases from July 2021 to September 2025. Revenue of the firm bought is as announced or reported in the deal record, for the 23 deals that give it, in the year each announcement gives. Earn-outs in the group’s debt are from Moody’s rating of April 2021.

We count each deal under the group that made it at the time, so one purchase made by a US firm a year before SOCOTEC bought it sits outside the count. Our TIC valuation pages credit each deal to its owner today and were compiled before this check, so they show a higher figure, 88. The table of competing buyers counts each buyer’s TIC deals since 2015 under its owner today, or at its profile’s count where it has one, with building and infrastructure deals as classed in our database.

The TIC medians come from our TIC valuation research, 2,841 deals since 2015, and use enterprise value. Fewer deals disclose EBITDA than disclose a price, so the medians use only the deals that do: 54 of the 2,841 across all TIC. Deal size is enterprise value where disclosed, otherwise the disclosed deal value; one of the 54 has neither, so the four bands hold 53. Euro figures are converted at $1.13 to the euro and pound figures at $1.32 to the pound, the 2025 averages.
