Sector Focus
Merv Capital sources off-market acquisition opportunities among independent, accredited calibration and industrial testing companies across the Midwest. This page tracks the consolidation of the calibration industry, who is acquiring, and what it means for founder-owned labs.
Calibration is one of the most fragmented service industries in the United States. Thousands of independent, founder-owned laboratories serve manufacturers, medical device companies, aerospace suppliers, utilities, and laboratories that are required to keep instruments within specification. The work is recurring by nature: calibration intervals, quality system requirements, and audit obligations bring customers back on a schedule.
That combination of fragmentation and recurring, compliance-driven revenue has drawn well-capitalized acquirers. Consolidation activity in calibration and metrology services has accelerated meaningfully over the past several years, and independent research firms have identified the calibration market as well suited to continued roll-up investment.
Calibration demand is structural. Every quality system that matters, from ISO 9001 to aerospace, automotive, and medical device standards, requires that measurement equipment be calibrated on a defined schedule with documented traceability. As long as things are manufactured, inspected, and audited, instruments must be calibrated. The work does not disappear in a downturn, because compliance does not pause.
Several forces are pushing demand higher. Manufacturing investment in the United States, including reshoring, semiconductor, medical device, and electrification projects, puts more instruments on more factory floors. Products and processes carry more sensors and tighter tolerances than they did a decade ago. And many manufacturers that once ran internal calibration departments now outsource the work to accredited third-party labs, both to reduce cost and because qualified metrologists are hard to hire and keep. Each of those trends turns into recurring work for independent calibration providers.
That is why acquirers describe calibration in the language of essential services: compliance-driven, recurring, and resilient. It is also why the limited number of well-run accredited independents in each region has become a sought-after asset.

| Accredited Labs | Private equity backed calibration platform (Incline Equity Partners) built through acquisitions of accredited independent labs | Has publicly announced a rapid series of lab acquisitions across the country since late 2023 and actively invites acquisition conversations |
| Trescal | Global calibration services group operating across dozens of countries | A long-running consolidator of calibration businesses internationally and in North America |
| SGS / Applied Technical Services | Global testing, inspection, and certification organization; ATS operates within SGS | Acquires calibration, testing, and inspection businesses as part of a broader TIC platform |
Transaction details above reflect public announcements and reporting. Every transaction is different, and past transactions do not establish a standard price or multiple for any other business.
For owners of independent calibration businesses, the current environment has practical implications. Well-run accredited labs with recurring customer bases are receiving serious interest, buyers are competing for a limited number of quality independents in each region, and owners who plan a transition early tend to have more options than owners who wait until they need to sell.
It also means owners are hearing from more people: platform development teams, brokers, and intermediaries of every kind. Our approach is different by design. We work for a small number of buyers, we approach owners directly and confidentially, and we introduce an owner to one qualified buyer rather than shopping a business around.
The most active acquirers of independent calibration businesses include Transcat, a publicly traded calibration and laboratory services company; Accredited Labs, a private equity backed platform that has completed a large number of lab acquisitions since 2023; Trescal, a global calibration group; and large testing organizations such as SGS through Applied Technical Services. Several regional platforms and independent investors are also active.
Buyers generally focus on recurring calibration revenue, ISO/IEC 17025 accreditation and scope, the mix of in-lab versus onsite work, customer diversification, technician depth, and whether the owner has a plan for transition. Labs with long customer relationships and documented quality systems tend to attract the strongest interest.
No. Merv Capital is compensated by buyers through a success fee that is due only if a transaction closes. Owners never pay us at any point, and a conversation carries no obligation.
No. Many of the best conversations start years before an owner is ready. If you have ever wondered what a transition could look like, we are happy to have a quiet, confidential conversation with no pressure and no timeline.
No. We do not list businesses, publish teasers with identifying details, or run auctions. Any information shared with a buyer is anonymized until you approve an introduction, and buyers sign confidentiality agreements before receiving detailed information directly from you.
A quiet, confidential conversation costs nothing and commits you to nothing. There is never a fee to owners, and you set the pace.
