NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN OR INTO AUSTRALIA, CANADA, HONG KONG, JAPAN, NEW ZEALAND OR SOUTH AFRICA OR IN ANY OTHER JURISDICTION IN WHICH THE TENDER OFFER WOULD BE PROHIBITED BY APPLICABLE LAW.

On January 10, 2023, Crayfish BidCo Oy (the "Offeror"), a Finnish private limited liability company indirectly controlled by the entities comprising Triton Fund V (together "Triton"), announced a voluntary public cash tender offer for all the issued and outstanding shares in Caverion Corporation ("Caverion" or the "Company") that are not held by Caverion or any of its subsidiaries (the "Shares" or, individually, a "Share") (the "Tender Offer"). On February 24, 2023, the Offeror announced that it has improved the Tender Offer by increasing the offer price thereunder to EUR 8.95 in cash for each Share validly tendered in the Tender Offer (the "Offer Price"). The Offeror has published a tender offer document, dated March 7, 2023, concerning the Tender Offer (the "Tender Offer Document"). The acceptance period under the Tender Offer commenced on March 8, 2023 at 9:30 a.m. (Finnish time) and initially expires on May 17, 2023 at 4:00 p.m. (Finnish time), unless the acceptance period is extended or discontinued.

The Finnish Financial Supervisory Authority has today approved a supplement to the Tender Offer Document (the "Supplement Document"). The Supplement Document relates to the stock exchange release published by North Holdings 3 Oy on March 8, 2023, in which North Holdings 3 Oy announced that it had decided to lower the acceptance threshold under its tender offer, the additional conditional purchases of Caverion Shares agreed by the Offeror after the date of the Tender Offer Document and the Offeror having concluded pending negotiations relating thereto, and the stock exchange release published by Caverion on March 9, 2023, in which the Board of Directors of Caverion commented on the pending tender offers by North Holdings 3 Oy and the Offeror, as well as the timing for issuance of the statement of the Board of Directors of Caverion on the tender offers (the "Caverion Stock Exchange Release"). The Supplement Document including the Caverion Stock Exchange Release is attached as Appendix to this release.

According to the Supplement Document, the additional conditional share purchases agreed by the Offeror after the date of the Tender Offer Document and concerning 13,703,398 Shares in aggregate (representing in total approximately 10.0 percent of all Shares in Caverion) may be terminated by either party if a third party announced a competing public tender offer for the Shares with a cash consideration payable immediately at completion being at least equal to or exceeding, as applicable, a certain threshold (as agreed in each case and being EUR 9.50 with respect to the additional conditional share purchases concluded by the date hereof), and the Offeror does not match or exceed the consideration offered in such competing offer within a certain period of time. The additional conditional share purchases concerning 13,59,131 Shares in aggregate (representing in total approximately 10.0 percent of all outstanding Shares in Caverion) are not subject to such termination right. The additional conditional share purchases concern 27,294,529 Shares in aggregate and will, once completed, increase the Offeror's total shareholding in Caverion to approximately 29.99 percent of all outstanding Shares from the Offeror's current shareholding of 9.9 percent and result in the Offeror becoming the largest shareholder in Caverion (assuming Caverion's current ownership structure would remain otherwise unchanged).

The Finnish language version of the Tender Offer Document and the Supplement Document will be available on the internet at www.triton-offer.com/fi and www.danskebank.fi/caverion as of March 14, 2023. The English language translation of the Tender Offer Document and this Supplement Document will be available on the internet at www.triton-offer.com and www.danskebank.fi/caverion-en as of March 14, 2023. In the event of any discrepancy between the two language versions of the Supplement Document, the Finnish language version shall prevail.

Information for shareholders of Caverion in the United States

The Tender Offer will be 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 being made in reliance on, and in compliance with, Rule 14d-1(c) under the US Securities Exchange Act of 1934, as amended. The Tender Offer is being made for securities of a non-US company. The Tender Offer is being made 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, any financial information included in this release has been prepared in accordance with applicable accounting standards in Finland (including International Financial Reporting Standards as adopted by the European Union), which may not be comparable to the financial statements or financial information of U.S. companies.

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 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. Any information about such purchases will be made public in Finland to the extent, and in the manner required, by Finnish law.

Neither the United States Securities and Exchange Commission nor any U.S. state securities commission has approved or disapproved the Tender Offer, passed upon the merits or fairness of the Tender Offer, or passed any comment upon the adequacy, accuracy or completeness of the disclosure in relation to the Tender Offer. Any representation to the contrary is a criminal offence in the United States. Caverion is organized under the laws of Finland, and the Offeror is organized under the laws of Finland. Some or all of the officers and directors of the Offeror and Caverion, respectively, are residents of countries other than the United States. In addition, most of the assets of the Offeror and Caverion are located outside the United States. As a result, it may be difficult for U.S. shareholders to enforce their rights and any claim they may have arising under the U.S. federal securities laws. U.S. shareholders may not be able to sue a foreign company or its officers or directors in a foreign court for violations of the U.S. securities laws, and it may be difficult to compel a foreign company and its affiliates to subject themselves to a U.S. court's judgement.
