Advent publishes Offer Prospectus for public tender offer for u-blox

Thalwil, Switzerland, 27 August, 2025 – Advent International, L.P. (“Advent”), a leading global private equity investor, through its indirect subsidiary ZI Zenith S.à r.l., today published the offer prospectus for its public tender offer for all publicly held registered shares of u-blox Holding AG (“u-blox”) (SIX: UBXN), a global provider of leading positioning and short-range communication technologies and services. The publication follows the publication of the pre-announcement on 17 August 2025.

The offer price amounts to CHF 135.00 net in cash per registered share in u-blox, valuing u-blox at approximately CHF 1.05 billion on a fully diluted basis and representing a 53% premium over the undisturbed volume-weighted average share price of the last six months prior to the pre-announcement, and a 32% premium to the undisturbed volume-weighted average share price of the last 60 trading days of u-blox shares until 14 August 2025, before the media first reported on a potential transaction.

The Board of Directors of u-blox has unanimously resolved to recommend acceptance of the offer, supported by an independent fairness opinion issued by IFBC Ltd., Zurich, which concluded that the offer price is fair from a financial point of view. SEO Master Fund LP, u-blox’s largest individual shareholder with around 9%, has irrevocably committed to tender all of its shares. The Board of Directors and the Executive Committee of u-blox have also agreed to tender all of their shares into the offer.

The main offer period is expected to begin on 11 September 2025, and to end on 9 October 2025, 04:00 PM CEST, subject to the conditions set forth in the offer prospectus, including customary regulatory approvals. Following settlement, Advent intends to initiate a squeeze-out procedure and to delist the u-blox shares from the SIX Swiss Exchange.

The tender offer will not be made, directly or indirectly, in any country or jurisdiction in which the tender offer would be considered unlawful or otherwise violate any applicable laws or regulations, or which would require Advent or any of its subsidiaries to change or amend the terms or conditions of the tender offer in any way, to make an additional filing with any governmental, regulatory or other authority or take additional action in relation to the tender offer.

Notice to U.S. Holders

Shareholders of u-blox in the United States (“U.S. Holders”) are advised that the registered shares of u-blox are not listed on a U.S. securities exchange and that u-blox is not subject to the periodic reporting requirements of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is not required to, and does not, file any reports with the U.S. Securities and Exchange Commission (the “SEC”) thereunder.

The tender offer will be made for the registered shares of u-blox, a Swiss company whose shares are listed on the SIX Swiss Exchange Ltd., and is subject to Swiss disclosure and procedural requirements, which are different from those of the United States. The tender offer will be made in the United States pursuant to Section 14(e) of, and Regulation 14E under, the Exchange Act, subject to the exemption provided under Rule 14d-1(c) under the Exchange Act for a tier 1 tender offer (the “Tier 1 Exemption”), and otherwise in accordance with the requirements of Swiss law. Accordingly, the tender offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, settlement procedures, waiver of conditions and timing of payments that are different from those applicable under U.S. tender offer procedures and laws. U.S. Holders are urged to consult with their own legal financial and tax advisors (including with respect to Swiss law) regarding the Offer.

As permitted under the Tier I Exemption, the settlement of the tender offer will be based on the applicable Swiss law provisions, which differ from the settlement procedures customary in the United States, particularly as regards to the time when payment of the consideration is rendered. The Offer, which will be subject to Swiss law, will be made to U.S. Holders in accordance with the applicable U.S. securities laws, and applicable exemptions thereunder, in particular the Tier I Exemption. To the extent the tender offer is subject to U.S. securities laws, those laws only apply to U.S. Holders of u-blox shares and will not give rise to claims on the part of any other person. It may be difficult for U.S. Holders to enforce their rights and any claim they may have arisen under the of U.S. federal securities laws, since u-blox is located in a non-U.S. jurisdiction, and some or all of their officers and directors may be residents of a non-U.S. jurisdiction. U.S. Holders may not be able to sue u-blox or its officers or directors in a non-U.S. court for violations of the U.S. securities laws. Further, it may be difficult to compel u-blox and its affiliates to subject themselves to a U.S. court's judgment.

Neither the SEC nor any securities commission of any State of the U.S. has (a) approved or disapproved of the tender offer; (b) passed upon the merits or fairness of the tender offer; or (c) passed upon the adequacy or accuracy of the disclosure in the pre-announcement. Any representation to the contrary is a criminal offence in the U.S.
