Disclosure policy

Reaktor complies in its communications with Finnish legislation, the provisions of the Market Abuse Regulation (EU No. 596/2014, as amended) ("MAR"), the rules and guidelines of Nasdaq Helsinki Ltd, as well as the guidelines of the European Securities and Markets Authority (ESMA) and the Finnish Financial Supervisory Authority. The Company also complies with the Finnish Corporate Governance Code and Reaktor’s internal rules and policies.

The Board of Reaktor Group has approved the company’s Disclosure policy on 4 June 2026.

Reaktor’s investor communications rely on these key principles:

• Openness and activeness
• Reliability
• Transparency and fairness

Reaktor publishes the financial statements release, the half-year report, and interim reports on a pre-announced schedule. The schedule is published before the start of an upcoming accounting period and are made available on Reaktor’s website.

For each financial year, Reaktor also publishes a corporate governance statement and a remuneration report. The Board of Directors' report may include a Sustainability report if so required or if one is prepared on a voluntary basis.

Reaktor publishes its releases in two categories:

• Stock exchange releases
• Press releases

Reaktor’s official reporting language is Finnish. All stock exchange releases are published in both Finnish and English.

Communication channels

The company’s primary channel for investor communications is its investor website at group.reaktor.com.

Silent period

Reaktor follows a 30-day silent period in its investor and media relations before the publications of the financial statements release, half-year report, and interim report. During this time, Reaktor will not give comments on its financial position, markets, or outlook, nor meet with capital market representatives.
