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.
