Lehto has previously announced its intention to transfer the trading venue of its shares from the Nasdaq Helsinki Stock Exchange (main list) to the First North Growth Market. Contrary to previous information, Lehto estimates that the transfer of the trading venue for the shares will not take place by the end of 2025, but only in the first half of 2026, when trading in the shares would also begin. Admission of shares to trading on the First North Growth Market requires the preparation of a prospectus and approval by Nasdaq Helsinki. Currently, trading in the shares is suspended. Financial development during the review period The Group's net sales from continuing operations, EUR 0.4 million, were at the level of the comparison period and consisted mainly of rental income from properties owned by the Group, electricity market incomes and income from the sale of inventories. The operating result from continuing operations was EUR -1.5 million (EUR -4.7 million in 1H24). The operating result was affected by low net sales, factory maintenance costs and costs related to the start-up of the energy construction business.

In this report, discontinued operations include Lehto Group Plc's subsidiaries that went bankrupt and the Swedish operations. The Group's cash and cash equivalents decreased to EUR 0.8 million (EUR 2.2 million on 31 December 2024). The decrease in cash and cash equivalents was mainly due to the loss-making result and investments in electricity storage projects. The Group's personnel decreased during the review period. At the end of June, the Group had 57 (76 on 31 December 2024) employees, of whom 50 (67 on 31 December 2024) were on full-time or part-time layoffs. The laid-off employees are employees of Lehto Components Oy. Energy construction business during the review period During the review period, Lehto's focus was on developing electricity storage projects and coordinating the technical requirements and commercial solutions for electricity storage. Among other things, Lehto signed several land lease agreements for electricity storage locations, prepared technical plans related to the sites, negotiated with electricity grid companies on connecting electricity storage to electricity grids, and obtained permits related to the construction of electricity storage. During the review period, Lehto started the construction of five new electricity storage projects with a total capacity of approximately 2.2 MW. At the end of the review period, the projects in question were still under construction. The commissioning of the electricity storage projects requires passing tests and approval from the transmission grid company Fingrid. The construction permit processes for electricity storage projects and the permit processes of electricity grid companies have required more time than expected. At the end of the review period, Lehto had 12 electricity storage projects in the development phase, with a combined capacity of approximately 55 MW. The company estimates that some of the projects under development will be ready for production by the end of 2025. The projects have been financed with cash and project-specific loans from external investors. Loans from investors amounted to approximately EUR 0.5 million during the review period. Lehto is also in negotiations for leasing and installment financing of batteries.

At the end of the review period, non-current assets were EUR 6.9 million and they mainly consist of Lehto Components Oy's Oulainen factory building and machinery and furniture. Non-current assets also include a total of EUR 1.5 million in ownerships and shares in real estate companies and one project company, as well as parts and components of electricity storage. Inventories, EUR 0.6 million, mainly consist of materials of Lehto Components Oy and finished products owned by Lehto Group Plc. Cash and cash equivalents decreased by EUR 1.7 million, which was due to a loss and investments in electricity storage. Non-current assets held for sale consist of lease rights related to Lehto Components Oy's Hartola factory, machinery and equipment. Liabilities The amount of financial liabilities increased by EUR 0.5 million during the review period as a result of loans taken out for electricity storage investments. At the end of the review period, the amount of financial liabilities was EUR 4.0 million, of which approximately EUR 3.5 million consists of secured RCF bank debt and approximately EUR 0.5 million of loans taken out for electricity storage investments. The RCF bank debt will be repaid according to the schedule specified in the company's restructuring program. The debt is secured by, among other things, all shares and most significant receivables of real estate companies owned by Lehto Group Oyj, as well as the assets of bankrupt subsidiaries. If the assets of the bankruptcy estates of subsidiaries are used to repay Lehto Group Oyj's RCF bank debt, the bankruptcy estates in question will become creditors of Lehto Group Oyj with the rights of the original creditor. Other liabilities are mainly unsecured liabilities according to the restructuring program and in addition, ordinary trade and accrued liabilities. Liabilities related to non-current assets held for sale are the realized and future rental obligations of Lehto Components Oy's Hartola factory in accordance with IFRS 16. Cash Flow Cash flow statement, EUR million 1-6/ 1-6/ 1-12/ 2025 2024 2024 Cash flow from operating activities Result for the period + adjustments to accrual-based items -0.9 -4.2 -5.4 Change in net working capital -0.1 -0.8 -0.4 Total cash flow from operating activities -1.1 -5.0 -5.8 Cash flow from investments -0.7 0.0 -0.2 Cash flow from financing 0.4 -0.5 2.0 Change in cash and cash equivalents -1.4 -5.4 -4.0 Cash and cash equivalents at the beginning of the year 2.2 6.1 6.1 Cash and cash equivalents at the end of the period 0.8 0.7 2.2 Financial outlook Due to uncertainties related to the initial phase of the business, Lehto does not provide a precise estimate of the development of its net sales or operating result in 2025. During 2025, Lehto aims to build significantly more new electricity storage capacity, which will be used primarily in the reserve and wholesale markets, but also in connection with the properties' own energy solutions. During 2026-2028, Lehto aims to build new electricity storage capacity so that the net sales generated from electricity storage in 2028 would be approximately EUR 25 million and the operating result would be more than 10% of net sales. The business requires significant battery investments, which will be acquired partly by leasing and partly by purchasing for its own balance sheet. The working capital needs of the initial phase of the business will be managed through capital investments specified in Lehto's restructuring program. Risks and uncertainties The most important risks for 2025 are described below. Liquidity and funding risk The company is in restructuring proceedings and in accordance with the restructuring program, the company's cash expenses can be financed in the following main aspects: · The company's current operating expenses will be paid with capital investments in accordance with the restructuring program and with the income flows from completed electricity storage projects. · The investments required by electricity storage projects will be financed with project-specific debt instruments. · Payments of restructuring liabilities will be financed by the sale of assets At the time of publication of this half-yearly report, the company does not have significant regular income flows. The company's current cash resources are not sufficient to cover the company's current expenses, investments required by electricity storage projects and payments in accordance with the restructuring program. In the last quarter of the year, the company will have to make repayments of restructuring liabilities of approximately EUR 2.2 million. Although Lehto's reserve and wholesale market yields are expected to grow during 2025, the company must succeed in selling its assets and/or obtaining new equity or debt financing to meet its payment obligations. Failure to raise capital or sell assets could result in the company being unable to meet its payment obligations. Risks related to starting and expanding the energy construction business The business is still in its early stages and its expansion requires, among other things, technical assessment and planning, building procurement channels, finding suitable energy project sites, operational implementation of projects, obtaining financing, and finding partners and building cooperation models. Failure to implement these may lead to delays in starting the business and a deterioration in liquidity. Risks related to the sale of factory operations The company is in negotiations to sell the factory operations of Lehto Components Oy. It is possible that the factory operations cannot be sold or the factory premises and equipment cannot be leased. In such a situation, the company would be left with cost burdens related to the maintenance of the factories and the company might not be able to meet its payments. Resolutions of the Annual General Meeting The Annual General Meeting held on 22 May 2025 decided, in accordance with the proposal of the Board of Directors, that no dividend be paid based on the approved balance sheet for the financial year 1 January - 31 December 2024. The number of members of the Company's Board of Directors was decided to be three. In accordance with the proposal of the Shareholders' Nomination Board, Timo Okkonen, Tarja Teppo and Hannu Lehto were re-elected as members of the Board of Directors. Jani Nokkanen had previously notified the Company that he was no longer available as a member of the Board of Directors. The term of office of the Board of Directors members will end at the Annual General Meeting in 2025. The Annual General Meeting authorized the Board of Directors to decide on the acquisition of the Company's own shares in one or more installments with funds belonging to the Company's unrestricted equity or without consideration, so that the maximum number of shares to be acquired is 16,200,000 shares. The amount corresponds to approximately 10 percent of all shares in the Company. The Annual General Meeting authorized the Board of Directors to decide on share issues and the issuance of stock options and other special rights entitling to shares, so that the Board of Directors is authorized to decide on the issuance of a total of 16,200,000 shares through a share issue or by issuing stock options or other special rights entitling to shares. The amount corresponds to approximately 10 percent of all shares in the company. The above-mentioned and other decisions of the Annual General Meeting are reported in the stock exchange release published on 22 May 2025. Events after the review period There are no events after the end of the review period that would have a material impact on Lehto's revenue, results or financial position. 20 August 2025 Lehto Group Plc Board of Directors Further information: Hannu Lehto, CEO +358 500 280 448 Veli-Pekka Paloranta, CFO +358 400 944 074 TABLES The preparation principles and calculation formulas for the half-yearly report are mainly the same as in the company's latest financial statements. The financial statements have been prepared on a going concern basis. The going concern basis has no effect on the valuation of balance sheet items, as the valuation of the Group's assets is based on an estimate of the recoverable amounts in situations where they fall below the carrying amount determined on a going concern basis.
