Sumer tops £1bn as TPG backs a continuation vehicle, not an outright sale

UK accountancy group Sumer has reached a reported valuation of more than £1bn in a deal that gives US investor TPG a leading position through a continuation vehicle, with existing backer Penta Capital staying on and no outright sale of the business. The move follows a roughly £1bn auction paused in May over valuation doubts. Elsewhere, the FRC publishes early-adoption guidance for revised ISA (UK) 700 and its 2026 Audit Quality Review, HLB Ireland makes its 13th acquisition, and Business Asset Disposal Relief sits at 18% against a 24% main CGT rate ahead of the 28 October Budget.
