Notes to the interim consolidated financial statements

1 Accounting and valuation principles

General disclosures

The consolidated semi-annual financial statements presented here comprise the unaudited semi-annual financial statements for the six months to 30 June 2026. This interim report has been prepared in accordance with Swiss GAAP FER 31 Complementary Recommendation for Listed Companies in abridged form, and should therefore be read in conjunction with the consolidated financial statements for the year to 31 December 2025.

In individual cases roundings can mean that figures in this report do not add up to the exact total specified, and that the specified percentages do not exactly result from the stated figures.

Repower’s consolidated semi-annual financial statements do not show any outstanding deferred tax assets or liabilities or current income taxes in relation to the OECD’s Pillar Two Model Rules. From today’s perspective, the group does not expect the minimum tax regulation to have any significant impact.

Dividends paid

On 13 May 2026, the annual general meeting of Repower AG approved the distribution of an ordinary dividend of CHF 5.00 per registered share plus a special dividend of CHF 0.50 per registered share for the 2025 financial year (prior year: dividend of CHF 5.00 plus a special dividend of CHF 1.50). Subsequently, on 20 May 2026, dividends of CHF 40,646 thousand (prior year CHF 48,037 thousand) were paid out.

Currencies

The following exchange rates were used as a basis for converting the figures in the income statement and balance sheet into CHF:

3 Changes in consolidations

Disposal of minority interest in Solis S.r.l.

On 3 March 2026, Repower Renewable S.p.A. sold shares representing a total of 49 per cent in Solis S.r.l. The shares were acquired by Sinloc Transition Energy Fund and Fondo Infrastrutture & Transition Energy, two funds managed by the asset management company Sinloc Investimenti Società di Gestione del Risparmio S.p.A. Following the conclusion of the transactions, Repower continues to hold 51 per cent of the shares in Solis S.r.l., which is still included in the consolidated financial statements as a subsidiary.

The disposal of the interest resulted in a loss of CHF 459 thousand. This arises from the difference between the selling price of CHF 5,910 thousand, on the one hand, and the disposal of 49 per cent of the proportionate net assets of CHF 5,676 thousand and the proportionate goodwill of CHF 693 thousand, on the other hand.

Pro-rata accumulated foreign exchange differences arising from losses of CHF 464 thousand were allocated directly to minority interests.

The selling price of CHF 5,910 thousand is recognised in cash flows from investing activities under the sale of minority interests.

In addition to the shares, 49 per cent of the shareholder loan was sold at the carrying amount. The selling price of CHF 4,925 thousand for the loan is recognised in cash flows from financing activities under the increase in financial liabilities.
