Peter Almberg, Chairman, comments:

"I believe the timing is ideal to offer both existing and potential new shareholders the opportunity to take part in the company's next phase. A phase that will include exits, improved cash flow and many new deals, all based on our modified and now proven business model. This marks the beginning of a new chapter and a renewed opportunity to create shareholder value. Let's go for it."

Anders Dahlgren, CEO, comments:

"We are truly grateful for the continued support from some of our key shareholders. Their strong commitment is reflected in the fact that approximately 48.5 percent of the rights issue has already been secured, a clear sign of confidence in Katalysen's new strategy and future. With this rights issue, we strengthen our ability to act where others hesitate, and continue building value through our hands-on model for investing in complex, opportunity-rich situations. At a time when many see obstacles, we see potential. This capital raise allows us to accelerate our momentum, support upcoming exit opportunities, and take the next step in broadening our reach across the Nordic and European innovation landscape."

Motive and use of proceeds

During 2024 and the first half of 2025, Katalysen has undergone a strategic transformation, shifting its focus from early-stage startup investments to a more targeted model for value creation in mature, founder-led companies facing complex challenges.

Through restructurings, management buyouts, and strategic pivots, Katalysen has developed a model that combines the best elements of venture capital and private equity at an early stage, a model the Company refers to as early-stage private equity. This model has already proven its potential, and with that experience as a foundation, the Company's direction is clear: to accelerate growth through high-quality transactions and continued hands-on engagement with its portfolio companies.

Katalysen sees increasing market opportunities arising from the current challenging macroeconomic environment, where fewer players are willing to act. The Company aims to be the active and solutions-oriented partner when others hesitate. However, in order to maintain the necessary pace and impact, Katalysen must strengthen its capital base. In the light of this, the Board of Directors has decided on the Rights Issue in order to:

• Finance new investments in line with the Company's special situations strategy,
• Strengthen operational capacity in current and upcoming portfolio initiatives,
• Support portfolio companies in exit processes and generate new liquidity events, and
• Build financial flexibility at a time when access to capital has become a competitive advantage.

Katalysen's ambition is to create returns not by predicting the future, but by acting where uncertainty breeds opportunity. This issue of shares provides both existing and new shareholders the opportunity to be part of Katalysen's continued growth journey and to help unlock the potential of the Company's expanding portfolio.

Terms for the Rights Issue

The Board of Directors of Katalysen has, by exercise of the authorization granted by the annual general meeting on 24 April 2025, resolved to carry out an issue of shares with preferential rights for existing shareholders of a maximum of 1,400,988 shares. Katalysen's existing shareholders have preferential rights to subscribe for shares in proportion to their existing shareholdings. The public also has the right to subscribe for shares in the Rights Issue.

One (1) existing share in the Company on the record date of 23 June 2025 entitles to seven (7) subscription rights. Forty-one (41) subscription rights entitle the holder to subscribe for one (1) share in Katalysen. The subscription price in the Rights Issue has been set at SEK 6.0 per share.

Subscription of shares must take place during the subscription period that runs from and including 24 June 2025, to and including 8 July 2025. Subscription rights that are not used during the subscription period become invalid and lose their value. Trading in subscription rights is expected to take place on Spotlight Stock Market from and including 24 June2025, to and including 3 July 2025. Trading in BTA (Paid Subscription Share) is expected to take place during the period from and including 24 June 2025, until the Rights Issue is registered with the Swedish Companies Registration Office.

The Rights Issue will increase the share capital by a maximum of SEK 182,128.44, from SEK 1,066,752.70 to SEK 1,248,881.14 and the total number of shares will increase by a maximum of 1,400,988 shares, from 8,205,790 shares to 9,606,778 shares. Existing shareholders who choose not to participate in the Rights Issue will be subject to a dilution effect corresponding to approximately 14.6 percent of the votes and capital, calculated on the number of shares in the Company after the Rights Issue has been fully subscribed. Shareholders who choose not to participate in the Rights Issue have the opportunity to partially compensate themselves for the financial dilution effect by selling their subscription rights no later than 3 July 2025.

Pre-subscription- and guarantee commitments

The Rights Issue is secured in writing by members of the board, management and existing shareholders to a total of 48.5 percent (corresponding to approximately SEK 4.1 million) through subscription and guarantee commitments (free-of-charge top guarantee). Subscription commitments amount to approximately SEK 1.6 million, which corresponds to approximately 19.6 percent of the Rights Issue. Guarantee commitments amount to a total of approximately SEK 2.4million, corresponding to approximately 28.9 percent of the Rights Issue.

No compensation is paid for the subscription commitments that have been submitted, or for the top guarantee.

Subscription and guarantee commitments are not secured by bank guarantee, blocking funds, pledging or similar arrangements.

Preliminary timetable

• Last day for trading in shares, including the right to receive subscription rights: 18 June 2025.
• First day for trading in shares, excluding the right to receive subscription rights: 19 June 2025.
• Record date for participation in the Rights Issue: 23 June 2025.
• Subscription period: 24 June 2025 - 8 July 2025.
• Trading in subscription rights: 24 June 2025 - 3 July 2025.
• Trading in BTA: from 24 June 2025, until the Rights Issue has been registered with the Swedish Companies Registration Office. The last day for trading in BTA will be announced through a separate press release after the Rights Issue has been completed.
• Press release on the outcome of the Rights Issue: around 9 July 2025.

The Overallotment Issue

In order to enable further capital additions in the event that the Rights Issue is oversubscribed, the board of the Company may use the Overallotment Issue. Upon full exercise of the Overallotment Issue, the Company will receive up to an additional SEK 3.0 million through a directed share issue of 500,000 shares at a subscription price of SEK 6.0 per share, corresponding to the subscription price in the Rights Issue. Any exercise of the Overallotment Issue will take place by the Board of Directors deciding on a directed share issue, conditional upon the approval of an extraordinary general meeting. The Overallotment Issue is intended to be used primarily to ensure that the top guarantors receive an allocation of shares corresponding to their underwriting commitment. In the event that the Overallotment Issue is fully exercised, the share capital will increase by an additional SEK 65,000, to SEK 1,313,881.14, which corresponds to a dilution of approximately 5.0 percent (calculated after the implementation of the Rights Issue). The Board of Directors believes that it is in the interest of both the Company and its shareholders that the Company, if applicable, is provided with additional capital in a time- and cost-effective manner while strengthening its capital base by gaining additional strong investors.

The maximum dilution effect through the Rights Issue and the Overallotment Issue amounts to approximately 18.8 percent.
