Proposals

Item 2 – Election of Chair of the general meeting
The Board of Directors proposes that Fredrik Lundén, member of the Swedish Bar Association, is elected as Chair of the general meeting.

Item 7 – Resolution to approve agreement allowing Acast's former CEO Ross Adams to continue to hold stock options and performance stock units

Outstanding share-related incentive programs
Acast currently has three outstanding share-related incentive programs adopted by the Annual General Meetings held on 9 May 2023 ("LTI 2023"), 21 May 2024 ("LTI 2024") and 20 May 2025 ("LTI 2025"). Acast's former CEO Ross Adams has, in his capacity as former CEO, participated in these share-related incentive programs and currently holds 950,000 employee stock options under LTI 2023, 900,000 performance stock units under LTI 2024 and 900,000 performance stock units under LTI 2025. The performance requirements under LTI 2023, LTI 2024 and LTI 2025 are as follows.

[1] These threshold levels are preliminary and based on certain assumptions, including the duration of the term of LTI 2023, LTI 2024 and LTI 2025, that Acast does not pay any dividend and that no recalculation of the threshold levels are made due to corporate actions or specific events.

Risk assessment in connection with CEO transition
On 10 May 2025, Acast announced that Ross Adams was temporary on medical leave for health- related reasons. On 22 June 2025, it was announced that, after serving for over ten years at the company and approximately eight as CEO, Ross Adams had informed the Board of Directors that he wished to resign from his position to continue in a role as strategic adviser within Acast. As part of the variation agreement made with Ross Adams, the Board of Directors evaluated various alternatives to ensure a smooth transition to the current CEO, Greg Glenday, with the aim of reducing risks for the company while achieving fair compensation to Ross Adams in light of his significant contributions to Acast's development during his time as CEO.

As part of the variation agreement, Ross Adams has agreed to be bound by, and comply with, certain restrictions until 30 June 2027, including (i) not taking up any employment whatsoever or providing any services directly or indirectly to any party as agent, consultant, director or employee prior to 1 July 2026 and (ii) adhering to non-competition provisions until 30 June 2027. These provisions have been considered crucial to Acast, considering Ross Adams' experience from and unique competence within the podcast industry and Acast, that competition is a key issue in the industry and to avoid that Ross Adams works for, or in any way contributes to, competitors of Acast or initiates new businesses within podcasting which could adversely affect Acast's business.

To achieve these objectives, pursuant to the variation agreement, Ross Adams continues to hold his stock options and performance stock units, which continue to vest according to their terms.

Reporting of costs in Acast's Q2 report
Costs related to the CEO transition, including the aggregated value of the employee stock options, and performance stock units under IFRS 2 have been valued and reflected in full as at the end of the period in Acast's interim report for the period 1 January 2025 – 30 June 2025. Variable social security costs are accounted for on an ongoing basis for the duration of the vesting period per accounting standards.

Changed conditions for visa in the U.S.
During the autumn, it has been established that it is no longer possible for Ross Adams to continue to be employed by Acast, and perform the role as strategic advisor, due to visa restrictions in the U.S., where he had relocated to at the request of the Board of Directors.

In consideration of Ross Adams agreeing to be bound by, and complying with, certain restrictions until 30 June 2027, as described above, and since the agreement included a full settlement between the parties, Acast has agreed to allow Ross Adams to continue to hold his stock options and performance stock units, even though his employment has been terminated. The Board of Directors has assessed that it is more advantageous to Acast, compared to other alternatives, including making additional cash payments to substitute the value of the stock options and performance stock units, to allow Ross Adams to continue to hold his stock options and performance stock units.

Proposal on continued holding
In view of the previous resolutions adopted by the Annual General Meetings in Acast on LTI 2023, LTI 2024 and LTI 2025, pursuant to which the intention has been that vesting of employee stock options and performance stock units is based on continued employment with Acast, the Board of Directors proposes that the Extraordinary General Meeting resolves to approve the agreement allowing Ross Adams to continue to hold his stock options and performance stock units in LTI 2023, LTI 2024 and LTI 2025. The Board of Directors has called for an Extraordinary General Meeting to resolve on this matter at this point in time as it forms part of the preparations for a potential transfer of Acast's listing to Nasdaq Stockholm Main Market (see "Preparations for transfer of listing" below).

No additional cost commitments
Approval of the Board's proposal will not result in additional cost commitments for Acast. Costs related to the CEO transition, including the total value of Ross Adams' employee stock options and performance stock units in accordance with IFRS 2, have been valued and reflected in full as at the end of the period in Acast's interim report for the period 1 January 2025 – 30 June 2025. Variable social security costs are accounted for on an ongoing basis for the duration of the vesting period per accounting standards. Whether or not the share-related incentive programs will vest and entitle to pay-out of shares will continue to be evaluated in accordance with the performance requirements of the programs.

Preparations for transfer of listing
Acast is currently preparing for a transfer of its listing from Nasdaq First North Premier Growth Market to Nasdaq Stockholm Main Market and the proposal by the Board of Directors in this item 7 is made as a step in completing the preparations for a potential transfer of Acast's listing to Nasdaq Stockholm Main Market.
