Fast-growing consolidator explores options
Accounting group Sumer, founded less than three years ago by former KPMG UK chief operating officer Warren Mead, is exploring a potential sale with hopes of hitting a £1bn valuation.
The firm has appointed boutique adviser Continuum to lead a strategic review, according to people familiar with the process.
The company, backed by private equity group Penta Capital, has grown rapidly since its launch in 2022, acquiring 34 firms in just over a year. Today, it employs 2,400 staff across 65 offices and is ranked the UK’s 13th largest accountancy provider.
Investor appetite fuels surge
Private equity interest in professional services has surged, overturning earlier reluctance to back firms with few hard assets and heavy reliance on key staff. Deals such as Grant Thornton’s sale of a stake to Cinven, valued at £1.5bn, and Evelyn Partners’ sale of Smith & Williamson to Apax Partners, have driven valuations higher.
Sumer’s consolidator model – buying majority stakes in small accountancy firms while allowing them to retain some independence – mirrors earlier attempts in the sector, such as John Connolly’s Azets. Backers argue that by integrating back-office operations while maintaining local branding, the group achieves both scale and flexibility.
Questions over valuation
Despite ambitious targets, industry advisers caution that Sumer may struggle to reach its £1bn goal. Typical valuations for accountancy groups run at 14–15 times earnings before interest, taxes, depreciation and amortisation. Some investors believe Sumer’s structure could attract a lower multiple, estimating a figure closer to £700mn.
Critics argue the semi-autonomous model makes the business less integrated and could require further effort from buyers to unify operations. However, sources close to Sumer maintain that finance, compliance and HR functions are already centralised.
Sector outlook
The rush of consolidation has sparked concerns about overheating in the market, with fears that inflated valuations may prove unsustainable. Some earlier consolidators struggled to deliver the returns private equity investors expected.
Still, with investor appetite running high, Sumer’s sale process will be closely watched as a test of just how far the current boom in accounting firm valuations can stretch.
