Advent Publishes Offer Prospectus for u-blox Public Tender

On 27 August 2025, Advent International published its offer prospectus for a public tender of all registered shares of u-blox Holding AG. The offer, through Advent's indirect subsidiary ZI Zenith S.à r.l., prices each u-blox share at CHF 135.00, valuing the company at CHF 1.05 billion. This represents a 53% premium over the six-month average share price before the pre-announcement and a 32% increase over the 60 trading days preceding initial media reports of the transaction.

u-blox's Board has unanimously recommended acceptance of the offer, underlined by an independent fairness opinion from IFBC Ltd. Additionally, SEO Master Fund LP, holding around 9% of u-blox shares, has committed to tender its shares. The offer period is scheduled from 11 September to 9 October 2025. Advent aims for a squeeze-out procedure and delisting from the SIX Swiss Exchange post-settlement.
