As communicated on 26 August 2025, the previous segment structure of Sweden and Rest of Nordics will be replaced by three reporting segments: Sweden, Norway and Finland, effective 1 January 2026. The new segment structure will be reported for the first time in the interim report for the first quarter of 2026, to be published on 29 April 2026.

The new reporting structure reflects the operational organisation introduced on 1 September 2025 and forms part of Instalco 2.0, Instalco’s group-wide programme to strengthen governance, follow-up and accountability across the organisation. The country-based structure enhances comparability, transparency and profitability tracking by country.

The restated information covers the financial years 2024 and 2025, with a quarterly breakdown for all eight quarters in the period (Q1 2024 - Q4 2025), and includes the following key performance indicators by segment:

• Order backlog
• Net sales
• EBITA
• EBITA margin

Total Group net sales and EBITA for the relevant periods are unchanged. The restatement relates solely to the allocation between segments.

The restated information has been compiled in accordance with Instalco's accounting policies as described in the most recent annual report. The restatement has been prepared for comparability purposes and has not been subject to review by the company's auditor.
