Swedish buyout firm EQT is taking British testing-and-certification giant Intertek private — a wager that the quiet business of verifying quality is worth billions.

By the numbers

EQT, the Swedish private-equity group, has agreed to acquire Intertek (LSE: ITRK), a British assurance, testing, inspection and certification company, for £9.3 billion. The deal would take a long-standing member of the FTSE 100 — the index of Britain’s largest listed companies — off the public market and into private ownership, one of the biggest such moves in London this year.

What Intertek actually does

Intertek belongs to an industry known by the initials ATIC: assurance, testing, inspection and certification. In plain terms, it is one of the referees of global trade. When a toy must be proven safe for children, when a shipment of fuel has to be checked for quality, or when a factory needs to show its products meet a country’s regulations, companies like Intertek run the tests and issue the certificates that let business proceed. Its work spans consumer goods, industrial equipment, and the oil, gas and power sectors. With around 45,000 employees and roots stretching back to marine surveying and laboratory testing in the 1880s, it is the kind of unglamorous but essential business that earns steady, repeatable fees year after year. Crucially, much of that work is required by law or demanded by customers, which makes the revenue both recurring and remarkably resilient to economic ups and downs.

Why EQT wants it

Private-equity firms prize exactly this profile: a global company that is hard to disrupt and generates predictable cash flows which hold up in good times and bad. Demand for testing and certification tends to rise rather than fall as the world grows more complex — as regulation tightens, as supply chains stretch across more countries, and as buyers demand proof that products are safe and authentic. Taking Intertek private gives EQT room to invest in the business, reshape it, and pursue acquisitions away from the quarterly glare and short-term scrutiny of public markets.

Why now

The timing is not accidental. Private-equity firms are sitting on large piles of committed capital they need to put to work, while higher interest rates have made many would-be targets cheaper and deterred rival corporate bidders. A cash-generative, globally diversified business like Intertek is especially well suited to carrying the debt that usually funds such deals, because its earnings are steady and spread across many industries and countries rather than riding on any single market. For a buyer with patience and deep pockets, that combination is close to ideal.

The least glamorous corner of global trade — checking that things are what they claim to be — just drew a £9.3 billion bid.

The bigger picture: London’s shrinking market

The deal also lands in the middle of a sensitive debate in Britain. A string of FTSE companies has been taken private or has shifted its listing abroad in recent years, fuelling worries that London’s public market is undervaluing its own companies and leaving them as bargains for overseas and private-equity buyers. Each high-profile take-private — and Intertek, at £9.3 billion, is decidedly high-profile — adds weight to the argument that something has gone wrong with how the City prices its champions.

Why it matters

For everyday readers, the lesson is twofold. First, some of the most resilient businesses in the world are the quiet ones working in the background, and patient investors will pay billions for dependable, “boring” cash flows. Second, when public markets persistently value a company below what private buyers think it is worth, ownership tends to migrate from ordinary shareholders to large private funds — a slow but consequential shift in who owns the economy’s best assets.

Key takeaways

• EQT agreed to take Intertek private for £9.3 billion, removing another company from the FTSE 100.
• Intertek tests, inspects and certifies products and supply chains — a steady, fee-based business.
• The deal feeds the debate over whether London-listed companies are being undervalued by public markets.
