IN PARTICULAR, THE TENDER OFFER IS NOT MADE IN AND THE TENDER OFFER DOCUMENT AND THIS SUPPLEMENT DOCUMENT MUST UNDER NO CIRCUMSTANCES BE DISTRIBUTED INTO AUSTRALIA, CANADA, THE HONG KONG SPECIAL ADMINISTRATIVE REGION OF THE PEOPLE’S REPUBLIC OF CHINA (“HONG KONG”), JAPAN, NEW ZEALAND OR SOUTH AFRICA OR ANY OTHER JURISDICTION WHERE PROHIBITED BY APPLICABLE LAW. SHAREHOLDERS IN THE UNITED STATES SHOULD ALSO REFER TO THE SECTION TITLED “INFORMATION FOR SHAREHOLDERS IN THE UNITED STATES” BELOW.

North Holdings 3 Oy (the “Offeror”) and Caverion Corporation (the “Company” or “Caverion”) have on November 3, 2022 entered into a combination agreement, which was amended on January 24, 2023 (as amended, the “Combination Agreement”), pursuant to which the Offeror has made a recommended voluntary public tender offer to acquire all of the issued and outstanding shares in Caverion that are not held by Caverion or any of its subsidiaries (the “Shares” or, individually, a “Share”) (the “Tender Offer”). The Offeror has on November 24, 2022 published a tender offer document, dated November 24, 2022, and published the first supplement document to the tender offer document on January 13, 2023 and the second supplement to the tender offer document on February 10, 2023, concerning the Tender Offer (the tender offer document, as supplemented from time to time, the “Tender Offer Document”). The offer period for the Tender Offer commenced on November 24, 2022, at 9:30 a.m. (Finnish time).

North (BC) Lux Holdco SARL (a vehicle owned and controlled by funds managed or advised by Bain Capital Private Equity (Europe), LLP, and/or its affiliates), Security Trading Oy, Fennogens Investments S.A. and Corbis S.A. form a consortium for the purposes of the Tender Offer.

Caverion published on February 9, 2023 its financial statements release for January 1, 2022 – December 31, 2022 (the “Financial Statements Release”), which also included the dividend proposal by the Board of Directors of Caverion to Caverion’s Annual General Meeting expected to be held on March 27, 2023. In addition, the Offeror’s financial statements for the financial year September 20, 2022 – December 31, 2022, have been audited. The Offeror therefore supplements the Tender Offer Document in accordance with Chapter 11, Section 11, Subsection 4 of the Finnish Securities Markets Act (746/2012, as amended) with the following information included in this document (the “Supplement Document”), and by adding the Financial Statements Release as Appendix I to the Tender Offer Document and the Offeror’s audited financial statements for the financial year September 20, 2022 – December 31, 2022 and the auditor’s report as Appendix J to the Tender Offer Document.

As set out in the terms and conditions of the Tender Offer, the consideration offered in the Tender Offer is subject to adjustment in certain situations, including where the record date of any dividend or other distribution of funds by Caverion occurs prior to any of the settlements of the completion trades of the Tender Offer, resulting in the distribution of funds not being payable to the Offeror. In such situations, the Cash Offer Price and the Alternative Consideration (as defined in the Tender Offer Document) payable by the Offeror shall be reduced accordingly on a euro-for-euro basis. Due to the dividend proposal announced by the Board of Directors of Caverion, the Offeror supplements the Tender Offer Document with the following information:

The section “Information on the Pricing of the Tender Offer – Grounds for Determining the Offer Price” shall be amended by adding the following paragraphs as the last paragraphs of the section:

“Caverion announced on February 9, 2023, in connection with its financial statements release, that the Board of Directors of Caverion proposes to the Annual General Meeting of Caverion to be held on March 27, 2023, that a dividend of EUR 0.20 per Share would be paid for the year 2022. In accordance with the terms and conditions of the Tender Offer, the Cash Offer Price and the Alternative Consideration are subject to adjustment in certain situations, including if the record date of any dividend or other distribution of funds by Caverion occurs prior to any of the settlements of the completion trades of the Tender Offer. Therefore, if the Annual General Meeting of Caverion decides on the distribution of a dividend, and if the record date of such dividend distribution occurs prior to any of the settlements of the completion trades of the Tender Offer, resulting in the distribution of such funds not being payable to the Offeror for Shares tendered in the Tender Offer either during the Offer Period or any Subsequent Offer Period, both the Cash Offer Price and the Alternative Consideration payable by the Offeror for such Shares will be reduced accordingly on a euro-for-euro basis. If Caverion would distribute a dividend of EUR 0.20 per Share, and the record date for such dividend would occur prior to any of the settlements of the completion trades of the Tender Offer, the Cash Offer Price for Shares settled after such dividend record date would be EUR 7.80 per Share, and the nominal amount of the Alternative Consideration Instruments or Deferred Payment Rights issued for Shares settled after such dividend record date would be EUR 8.30 per Share.

If the Offer Period expires on February 28, 2023, and the Tender Offer is completed, the Completion Date under the terms and conditions of the Tender Offer would occur by March 27, 2023, and the Offer Price payable for Shares tendered into the Tender Offer by February 28, 2023 would not be subject to adjustment for the dividend, and any dividend recorded by Caverion after March 27, 2023 would be payable to the Offeror. However, if the Offer Period is extended or in the event of a Subsequent Offer Period, it is possible that the record date of the dividend proposed to the Annual General Meeting would occur prior to the settlement of some or all of the completion trades of the Tender Offer, in which case the Cash Offer Price and Alternative Consideration would be adjusted as described above with respect to such Shares which are not settled to the Offeror at the time of the record date of the dividend.”

As described in the Tender Offer Document, the Offeror has prepared the first financial statements for the financial period of September 20, 2022 – December 31, 2022 in accordance with the Finnish Accounting Standards (“FAS”). The Offeror’s financial statements for the financial year September 20, 2022 – December 31, 2022 have been audited. Consequently, the Offeror amends the following sections of the Tender Offer Document as follows:

The table under the section “Summary Relating to the Alternative Consideration – Key Information on the Offeror – What Is the Key Financial Information Regarding the Offeror?” as well as the tables concerning Offeror’s income statement and balance sheet the under the section “Financial and Other Information” shall be amended by replacing the word “unaudited” with word “audited”.

The Offeror’s audited financial statements for the financial year September 20, 2022 – December 31, 2022 and the auditor’s report shall be added as Appendix J to the Tender Offer Document.

Caverion published on February 9, 2023 its financial statements release for January 1, 2022 – December 31, 2022. Consequently, the Offeror amends the following sections of the Tender Offer Document as follows:

The first and second paragraphs of the section “Presentation of Caverion – Future Prospects Published by Caverion” shall be amended by replacing the following strikethrough passage with the passage that is underlined and set in bold:

“The future prospects of Caverion have been described in ~~the unaudited interim report of Caverion as at and for the nine months ended September 30, 2022~~ Caverion’s financial statements release for January 1, 2022 – December 31, 2022. See “~~Annex A: Financial Information of Caverion~~ Annex I: Caverion’s financial statements release for January 1, 2022 – December 31, 2022.

Information on risks to which Caverion is exposed has been presented in the annual report 2021 of Caverion published on March 2, 2022. Further information on Caverion’s short-term risks has been presented on ~~page 18 of the interim report published by Caverion on November 3, 2022~~ page 16 of Caverion’s financial statements release for January 1, 2022 – December 31, 2022.”

The Finnish language versions of the Tender Offer Document and this Supplement Document are available on the internet at www.caverion-offer.fi and www.nordea.fi/caverion-ostotarjous as of February 15, 2023. The English language translations of the Tender Offer Document and this Supplement Document are available on the internet at www.caverion-offer.com and www.nordea.fi/caverion-offer as of February 15, 2023.

The Finnish Financial Supervisory Authority (the “FIN-FSA”) has approved the Finnish language version of this Supplement Document but the FIN-FSA assumes no responsibility for the accuracy of the information presented therein. The decision number of the approval of the FIN-FSA is FIVA/2023/297. This Supplement Document has been translated into the English language. In the event of any discrepancy between the two language versions of the Supplement Document, the Finnish language version shall prevail.

The Tender Offer is not being made, directly or indirectly, in or into Australia, Canada, Hong Kong, Japan, New Zealand or South Africa and the Tender Offer Document and this Supplement Document and any and all materials related thereto should not be sent in or into Australia, Canada, Hong Kong, Japan, New Zealand or South Africa (including by use of, or by any means or instrumentality, for example, e-mail, post, facsimile transmission, telephone or internet, of interstate or foreign commerce, or any facilities of a national securities exchange), and the Tender Offer cannot be accepted directly or indirectly or by any such use, means or instrumentality, in or from within Australia, Canada, Hong Kong, Japan, New Zealand or South Africa. Accordingly, copies of the Tender Offer Document and this Supplement Document and any related materials are not being, and must not be, mailed, forwarded, transmitted or otherwise distributed or sent in or into or from Australia, Canada, Hong Kong, Japan, New Zealand or South Africa or, in their capacities as such, to custodians, trustees, agents or nominees holding Shares for Australian, Canadian, Hong Kong, Japanese, New Zealander or South African persons, and persons receiving any such documents (including custodians, nominees and trustees) must not distribute, forward, mail, transmit or send them in, into or from Australia, Canada, Hong Kong, Japan, New Zealand or South Africa. Any person accepting the Tender Offer shall be deemed to represent to the Offeror such person’s compliance with these restrictions and any purported acceptance of the Tender Offer that is a direct or indirect consequence of a breach or violation of these restrictions shall be null and void.

Shareholders of Caverion in the United States are advised that the shares in Caverion 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 the Tender Offer Document and this Supplement Document 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 the Tender Offer Document and this Supplement Document, 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 the Tender Offer Document and this Supplement Document 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 THIS SUPPLEMENT DOCUMENT OR PASSED ANY COMMENT ON WHETHER THE CONTENT IN THE TENDER OFFER DOCUMENT OR IN THIS SUPPLEMENT DOCUMENT IS CORRECT OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE IN THE UNITED STATES.

This Supplement Document includes “forward-looking statements”, including statements about the expected timing and completion of the Tender Offer. Generally, words such as may, should, could, aim, will, would, expect, intend, estimate, anticipate, believe, plan, seek, contemplate, envisage, continue or similar expressions identify forward-looking statements.

These statements are subject to risks, uncertainties, assumptions and other important factors, many of which may be beyond the control of the Offeror and could cause actual results to differ materially from those expressed or implied in these forward-looking statements.

Factors that could cause actual results to differ from such statements include: the occurrence of any event, change or other circumstances that could give rise to the termination of the Tender Offer, the failure to receive, on a timely basis or otherwise, the required approvals by government or regulatory agencies, the risk that a condition to consummating the Tender Offer may not be satisfied, the ability of Caverion to retain and hire key personnel and maintain relationships with customers, suppliers and other business partners pending the completion of the Tender Offer, and other factors.

Although the Offeror believes that the expectations reflected in such forward-looking statements are based on reasonable assumptions, no assurance can be given that such statements will be fulfilled or prove to be correct, and no representations are made as to the future accuracy and completeness of such statements. The Offeror undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable laws or by any appropriate regulatory authority.

Q4/2022 | 3 Jacob Götzsche, President and CEO: †Qol s_[l 4244 q[m g[le_^ \s [ ]f_[l jli’cn[\cfcns ojfc’n [m [ l_mofn i’ nb_ determined performance improvement actions made during the past years. Our revenue grew by 9.9 percent to EUR 2,352.1 (2,139.5) million and adjusted EBITA increased by 20.7 percent to EUR 105.8 (87.7) million in line with our guidance. Our EBITA was record-high during our nearly ten-year history as a publicly listed company and amounted to EUR 86.1 (59.4) million in 2022. Our earnings per share almost doubled from 2021. The performance improvement was supported by the overall revenue growth mainly in Services. In addition, our consistent efforts in improving project risk management have gradually resulted in healthier and more profitable project portfolio. This demonstrates our strong capability to deliver sustainable, profitable growth in line with our strategy that was updated during the year. The positive momentum of the first nine months of the year continued also in the fourth quarter of 2022. Our fourth quarter revenue increased by 16.7 percent to EUR 682.9 (585.3) million and organic growth was 14.9 percent. The organic growth was partially driven by the increased costs of materials and external services, that we were able to successfully factor in our sales prices. We estimate this inflation impact to account for roughly one third of the organic growth. Our adjusted EBITA improved by 28.7 percent to EUR 38.7 (30.1) million, or 5.7 (5.1) percent of revenue during the fourth quarter of 2022, even though the high sick leave levels and operating expense increases continued to negatively impact our profitability. Overall, our business has however proved to be relatively resilient to the rapid inflation. I am also pleased that we could improve our operating cash flow before financial and tax items to EUR 106.9 (76.7) million in the fourth quarter. Our order backlog amounted to EUR 1,943.3 (1,863.8) million at the end of December, 4.3 percent higher compared to the previous year. We expect our solid order backlog to support revenue growth also going forward. Around 63.2 percent of our order backlog is estimated to be realised as revenue during 2023. The high inflation still continues to have some impact on the building technology market, although we have seen some first signs of the material price inflation cooling down. In 2023, we expect the underlying demand to be overall positive in Services. In Projects, we expect the underlying business activity to remain stable in 2023, however, the economic uncertainty may start to impact the demand environment negatively. The effects of the corona pandemic continued to stabilise during the fourth quarter. We remain somewhat cautious with the pandemic as unpredictable virus variants and new waves of the pandemic may continue to emerge. As part of the implementation of our Sustainable Growth strategy, we closed 12 acquisitions in 2022 with total annual revenue of EUR 94.3 million and welcomed more than 560 new colleagues from the acquired companies. In the fourth quarter, we closed three acquisitions bringing us additional capabilities in smart security services, refrigeration and technical installation. Our fourth quarter revenue increased by 4.1 percent as a result of acquisitions and divestments compared to the previous year. We continue to screen high quality companies that complement our existing capabilities or geographical footprint. As we close the year 2022 with strong results, I would like to thank our customers, partners, shareholders and our almost 14,500 employees for their contribution during our journey so far.

The war has created uncertainties weakening the growth prospects in several countries where Caverion operates. The duration of the Ukrainian conflict and its future effects on the industry, and Caverion in particular, remain uncertain, and the overall situation remains highly volatile. Caverion divested its Russian subsidiary at the end of 2021 and has no operations in Ukraine or Belarus. Therefore, the impact of the conflict on Caverion is currently indirect. Caverion has experienced increases in material prices and delays in the supply chain and in decision-making, however Caverion continued to manage them on a daily basis without having a significant impact on performance during 2022. Market outlook for 2023 Caverion expects the underlying demand to be overall positive in Services during 2023. In Projects, Caverion expects the underlying business activity to remain stable in 2023. In Projects, however, the economic uncertainty may start to impact the demand environment negatively. The market instability resulting from the war in Ukraine and the high inflation are expected to dampen the willingness to invest in new construction. This scenario assumes a sufficient control of the corona pandemic impacts with no significant unforeseen setbacks in 2023 and no further escalation of the conflict in Ukraine.

Q4/2022 | 6 Operating environment in the fourth quarter and in 2022 The economic uncertainty increased during 2022 due to the geopolitical tensions related to the Ukraine conflict, resulting in subsequent energy crisis, mounting inflation, rising interest rates and lowered economic growth prospects. Inflation accelerated during the year and the cost inflation related to material prices, including fuel costs, continued to impact also the building technology market. There have also been supply shortages and delays in some areas. Caverion has proactively taken various measures to optimise the supply chain and to manage pricing. Economic sentiment weakened in the EU during 2022 along with lower economic growth prospects. Also the corona pandemic still continued to have some impact on the operating environment through sick leaves. In Services, the market demand and general investment activity remained positive. Caverion has continued to see a general increasing interest for services supporting sustainability, such as energy management and advisory services, driven by regulation and by the expected governmental and EU stimulus packages supporting investments in green growth. There has also been increasing interest towards long-term and large-scale service agreements. Growth has been limited by the availability of competent workforce and delays in the supply chain. In Projects, the market demand remained mostly stable. The interest for energy improvement projects has picked up, driven by the focus on energy consumption due to the energy crisis. The market was impacted by increases in material prices, delays in decision-making and supply chain as well as uncertainty in the business environment, especially related to new construction.

SIGNIFICANT SHORT-TERM RISKS AND UNCERTAINTIES NZWdW ZShW TWW’ ‘a _SfWd[S^ UZS’YWe [’ =ShWd[a’}e significant short-term risks and uncertainties reported in the Interim Report Q3/2022. Those risks and uncertainties are still valid. The most significant factor creating uncertainty is the war in Ukraine and its potential implications on the operating environment of Caverion. The impacts of the war a’ =ShWd[a’}e business during 2022 have been described earlier in nb_ l_jiln ch †Kgj[]nm of the Ukraine war a’ =ShWd[a’}e \omch_mm ^olcha 4244‡0 Further escalation or prolongation of the conflict or regional unrest in neighbouring areas could negatively affect Caverion’s operating environment. The short-term risks related to the lack of availability of materials and supply as well as the increase in material prices are still valid. The same applies to the risk of rising energy and fuel prices. Possible problems with the availability and cost of materials, labour, energy and fuel may impact the operating environment in the near future. These risks have already partly materialised. The key measures how Caverion is managing the situation include price increase clauses in tenders and agreements covering these costs. The soaring inflation in the EU countries poses several risks and may lead to a recession within the EU and also wider. The situation may have an impact on the market demand going forward due to a weakening economic sentiment. The potential risk is balanced by the growing need for energy efficiency in the built environment where Caverion is able to support its customers. Cyber risks have increased due to the Ukraine crisis. There have been concrete cases of cyber-attacks on business enterprises and government authorities. Government authorities have warned of an increasing amount of cyber-attacks. Caverion has improved the Ua_bS’k}e UkTWd eWUgd[fk abWdSf[a’e S’V fWUZ’a^aY[We continuously and is well prepared against cyber security threats. However, it cannot be excluded that also Caverion could face cyber-attacks with potential impact on operations.

The commencement of each new plan within the structure is conditional on a separate Board approval. Share allocations within the Restricted Share Plan will be made for individually selected key employees in specific situations. Each RSP plan consists of a three-year vesting period after which the allocated share rewards will be delivered to the participants provided that their employment with Caverion continues at the time of the delivery of the share reward. The potential share rewards based on the Restricted Share Plans for 2020›2022, 2021›2023 as well as 2022›2024 total a maximum of approximately 480,000 shares (gross before the deduction of applicable payroll tax).

Caverion monitors the risks closely and at the moment does not see any need for changes in the risk management principles. The risks related to the availability of financing, the availability of guarantee facilities as well as foreign exchange and interest rate related risks are in control. The objective of capital management in Caverion Group is to maintain an optimal capital structure, maximise the return on the respective capital employed and to minimise the cost of capital within the limits and principles stated in the Treasury Policy.

We have audited the financial statements of North Holdings 3 Oy (business identity code 3313575-3) for the first year of operation ended 31 December, 2022. The financial statements comprise the balance sheet, income statement, and notes.

In our opinion, the financial statements give a true and fair view of the company’s financial performance and financial position in accordance with the laws and regulations governing the preparation of financial statements in Finland and comply with statutory requirements.

We conducted our audit in accordance with good auditing practice in Finland. Our responsibilities under good auditing practice are further described in the Auditor’s Responsibilities for the Audit of Financial Statements section of our report. We are independent of the company in accordance with the ethical requirements that are applicable in Finland and are relevant to our audit, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

The Board of Directors are responsible for the preparation of financial statements that give a true and fair view in accordance with the laws and regulations governing the preparation of financial statements in Finland and comply with statutory requirements. The Board of Directors are also responsible for such internal control as they determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Board of Directors are responsible for assessing the company’s ability to continue as going concern, disclosing, as applicable, matters relating to going concern and using the going concern basis of accounting. The financial statements are prepared using the going concern basis of accounting unless there is an intention to liquidate the company or cease operations, or there is no realistic alternative but to do so.

Our objectives are to obtain reasonable assurance on whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with good auditing practice will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial statements.

As part of an audit in accordance with good auditing practice, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.
