HELSINKI, March 10, 2023 /PRNewswire/ -- Caverion Corporation ("Caverion") supplements its stock exchange release published on March 8, 2023, with the following information:

As announced on January 24, 2023, Elo Mutual Pension Insurance Company, Ilmarinen Mutual Pension Insurance Company, Mandatum Life Insurance Company Limited and Varma Mutual Pension Insurance Company, together representing approximately 15.4 percent of Caverion's all issued and outstanding shares (the "Shares") and votes, have previously renewed their irrevocable undertakings to accept the tender offer by North Holdings 3 Oy ("North Holdings") for all the Shares (the "Tender Offer"), and Veritas Pension Insurance Company Ltd., which holds approximately 0.6 percent of all Shares and votes in Caverion, has given an irrevocable undertaking to accept the Tender Offer (the "Irrevocables"). These Irrevocables may be terminated in the event that a competing offer is announced by a third party with a consideration of at least EUR 8.95 per Share and North Holdings does not match or exceed the consideration offered in such competing offer within a certain period of time. Since Crayfish BidCo Oy has announced an improved competing tender offer with an offer consideration of EUR 8.95 per Share and North Holdings has not matched or exceeded the consideration offered in said improved competing tender offer, the understanding of the Board of Directors of Caverion is that the Irrevocables have seized to be in effect.

Information for shareholders of Caverion in the United States

Shareholders of Caverion in the United States are advised that the Shares are not listed on a U.S. securities exchange and that Caverion 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 is made for the issued and outstanding shares of Caverion, which is domiciled in Finland, and is subject to Finnish disclosure and procedural requirements. The tender offer is made in the United States pursuant to Section 14(e) and Regulation 14E under the Exchange Act, subject to the exemption provided under Rule 14d-1(c) under the Exchange Act for a Tier I tender offer (the "Tier I Exemption") and Rule 802 (the "802 Exemption") under the U.S. Securities Act of 1933 (the "U.S. Securities Act"), and otherwise in accordance with the disclosure and procedural requirements of Finnish law, including with respect to the tender offer timetable, settlement procedures, withdrawal, waiver of conditions and timing of payments, which are different from those of the United States. In particular, the financial information included in this stock exchange release has been prepared in accordance with applicable accounting standards in Finland, which may not be comparable to the financial statements or financial information of U.S. companies. The tender offer is made to Caverion's shareholders resident in the United States on the same terms and conditions as those made to all other shareholders of Caverion to whom an offer is made. Any informational documents, including this stock exchange release, are being disseminated to U.S. shareholders on a basis comparable to the method that such documents are provided to Caverion's other shareholders.

As permitted under the Tier I Exemption, the settlement of the tender offer is based on the applicable Finnish 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 tender offer, which is subject to Finnish law, is being made to the U.S. shareholders in accordance with the applicable U.S. securities laws, and applicable exemptions thereunder, in particular the Tier I Exemption and the 802 Exemption. To the extent the tender offer is subject to U.S. securities laws, those laws only apply to U.S. shareholders and will not give rise to claims on the part of any other person. U.S. shareholders should consider that (whether paid initially in cash or upon redemption of any alternative consideration instruments) the offer price for the tender offer is being paid in EUR and that no adjustment will be made based on any changes in the exchange rate.

To the extent permissible under applicable law or regulations, the offeror and its affiliates or its brokers and its brokers' affiliates (acting as agents for the offeror or its affiliates, as applicable) may from time to time after the date of this stock exchange release and during the pendency of the tender offer, and other than pursuant to the tender offer, directly or indirectly purchase or arrange to purchase Shares or any securities that are convertible into, exchangeable for or exercisable for Shares. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. To the extent information about such purchases or arrangements to purchase is made public in Finland, such information will be disclosed by means of a press release or other means reasonably calculated to inform U.S. shareholders of Caverion of such information. In addition, the financial advisers to the offeror may also engage in ordinary course trading activities in securities of Caverion, which may include purchases or arrangements to purchase such securities. To the extent required in Finland, any information about such purchases will be made public in Finland in the manner required by Finnish law.

Neither the SEC nor any U.S. state securities commission has approved or disapproved the tender offer (including the offer of the alternative consideration instruments), passed upon the merits or fairness of the tender offer (including the offer of the alternative consideration instruments), or passed any comment upon the adequacy, accuracy or completeness of the disclosure in relation to the tender offer (including in relation to the alternative consideration instruments). Any representation to the contrary is a criminal offence in the United States.

THE ALTERNATIVE CONSIDERATION INSTRUMENTS HAVE NOT BEEN, AND WILL NOT BE, REGISTERED UNDER THE SECURITIES ACT OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER JURISDICTION, AND THE ALTERNATIVE CONSIDERATION INSTRUMENTS CONSTITUTE "RESTRICTED SECURITIES" PURSUANT TO THE SECURITIES ACT, AND MAY NOT BE OFFERED OR SOLD WITH UNITED STATES OR TO, OR FOR, THE ACCOUNT OR BENEFIT OF, U.S. PERSONS (AS DEFINED IN REGULATION S UNDER THE SECURITIES ACT), EXCEPT PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE OR LOCAL SECURITIES LAWS.

The receipt of cash pursuant to the tender offer by a U.S. shareholder may be a taxable transaction for U.S. federal income tax purposes and under applicable U.S. state and local, as well as foreign and other, tax laws. Each holder of Shares is urged to consult its independent professional advisers immediately regarding the tax and other consequences of accepting the tender offer.

It may be difficult for Caverion's shareholders and the holders of the alternative consideration instruments to enforce their rights and any claims they may have arising under the U.S. federal securities laws, since the offeror and Caverion are located in a non-U.S. jurisdiction and some or all of their respective officers and directors may be residents of non-U.S. jurisdictions. Caverion shareholders and the holders of the alternative consideration instruments may not be able to sue the offeror or Caverion or their respective officers or directors in a non-U.S. court for violations of the U.S. federal securities laws. It may be difficult to compel the offeror and Caverion and their respective affiliates to subject themselves to a U.S. court's judgment.

NEITHER THE U.S. SECURITIES AND EXCHANGE COMMISSION NOR ANY U.S. STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED THE TENDER OFFER, PASSED ANY COMMENTS UPON THE MERITS OR FAIRNESS OF THE TENDER OFFER, PASSED ANY COMMENT UPON THE ADEQUACY OR COMPLETENESS OF THE TENDER OFFER DOCUMENT OR THE SUPPLEMENT DOCUMENT OR PASSED ANY COMMENT ON WHETHER THE CONTENT IN THE TENDER OFFER DOCUMENT OR THE SUPPLEMENT DOCUMENT IS CORRECT OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE IN THE UNITED STATES.

Bank of America Europe DAC, Stockholm branch, a subsidiary of Bank of America Corporation, is acting exclusively for Caverion and no one else in connection with the tender offer and the matters set out in this stock exchange release, and will not be responsible to anyone other than Caverion for providing the protections afforded to its clients or for providing advice in relation to the tender offer or any matter or arrangement referred to in this stock exchange release.
