^{}[] ADDTECH

9b. Resolution regarding allocation of the Company's profits in accordance with the duly adopted Balance Sheet

The Board of Directors proposes that the profit is allocated so that MSEK 972 (864) is distributed to shareholders and that the remaining part of the Company's earnings, MSEK 820 (579), is carried forward.

This means that the Board of Directors proposes to distribute to the shareholders a dividend of SEK 3.60 (3.20) per share and that 28 August 2026 shall be the record date for receiving the dividend.

If the Annual General Meeting resolves in accordance with the proposal, the dividend is estimated to be transferred through Euroclear Sweden AB on 2 September 2026 to those who are registered in the share register on the record date.

15. Resolution of remuneration report

The Board of Directors proposes that the Meeting resolves to approve the Board's report regarding remuneration for 2025/2026 pursuant to Chapter 8, section 53 a of the Swedish Companies Act.

16. Resolution regarding issuing call options for repurchased shares and the transfer of repurchased shares to management personnel (the "2026 Share-Related Incentive Scheme")

The Board of Directors proposes that the Annual General Meeting should pass a resolution to adopt a long-term incentive scheme, the 2026 Share-Related Incentive Scheme (the "Scheme"). The Scheme is proposed to include approximately 150 members of management personnel within the Addtech Group in which the participants are being given the opportunity to acquire, at market price, call options relating to class B shares in Addtech repurchased by the Company, with the participants receiving a certain subsidy on premiums paid for the options after two years.

The proposal of the Board of Directors also means that the Annual General Meeting approves that the Company transfers – with deviation from the shareholders' preferential rights – up to 1,000,000 of the Company's repurchased class B shares to the option holders at the agreed exercise price in connection with any exercise of the call options (subject to any recalculations). The Board of Directors' proposal ultimately means that the Annual General Meeting approves that the Series B shares that the Company acquired in accordance with previous authorisation are allowed to be transferred in order to secure delivery of shares under the proposed Scheme. The Company currently holds a total of 2,714,958 shares of series B in the Company.

This proposal has been prepared by the Company's Remuneration Committee in consultation with the Company's Board of Directors. The decision to propose the Scheme to the Annual General Meeting has been taken by the Board of Directors. The Company's directors, who are not employees of the company, are not included in the Scheme.

The Scheme involves the following main terms and conditions:

a) The number of call options to be issued shall not exceed 1,000,000, corresponding to approximately 0.4 percent of the total number of shares and approximately 0.3 percent of the total number of votes in the Company (class B shares held by the Company are included). Each call option entitles the holder to acquire one (1) repurchased class B share in the

^{}[] ADDTECH

Company during the period from 10 September 2029 to 7 June 2030. Shares may not, however, be purchased during any such period when trading in the Company's shares is forbidden in accordance with regulation (EU) no 596/2014 of the European Parliament and of the Council of April 16, 2014 on Market Abuse (or any other equivalent legislation which applies at any given time).

b) The purchase price for shares ("Purchase price") upon exercise of the options shall correspond to 120 percent of the volume-weighted average of the price paid for the Company's B shares on Nasdaq Stockholm during the period from 27 August 2026 to 9 September 2026.

c) The right to acquire the call options shall be granted to the Group management and further approximately 20 members of management in the Addtech Group as well as a number of the subsidiaries' managing directors. Persons who have a direct opportunity to influence the Group's results. Addtech's CEO shall be offered a maximum of 40,000 call options, others in Group management shall be offered a maximum of 25,000 call options per individual and other executives shall be offered a maximum of 12,500 call options.

d) If a person who is entitled to an allocation refrains in full or in part from acquiring call options offered to them, such un-acquired call options shall be divided on a pro rata basis between those persons who are entitled to an allocation and who have, in writing, expressed their interest in acquiring additional call options. Persons who are entitled to an allocation may not come to acquire more than an additional 30 percent of the original number of call options offered in this manner.

e) The Board of Directors shall establish the final distribution of call options according to the principles outlined in items c) and d) above, as well as the number of call options the employees within each category shall be offered to acquire.

f) Notice of acquiring call options must be given no later than 16 September 2026. The Board of Directors of the Company shall be entitled to extend the period for notification of acquisition.

g) The premium for the call options shall correspond to the market value of the call options according to an external independent valuation, applying the Black-Scholes model. The measuring period for calculating the option premium will be based on the volume-weighted average of the price paid for the shares of class B in the Company on Nasdaq Stockholm during the period from 3 September 2026 until 9 September 2026.

h) Issuing call options to employees outside Sweden is dependent on tax effects, that there is no legal impediment, and that the Board of Directors determines that such allocation can be carried out with reasonable administrative and financial resources. The Board of Directors shall be entitled to make such minor amendments to the Scheme as required by applicable foreign legislation and regulations.

i) The call options are freely transferable.

j) The number of shares which the call options bring entitlement to acquire and the exercise price may be recalculated as a result of e.g. bonus issues, share consolidations or splits, new

^{}[] This is a translation of the Swedish original. In case of any discrepancies between this translation and the Swedish original, the latter shall prevail.

issues, a reduction in the share capital or similar actions. The time at which shares are transferred may be brought forward as a result of any merger or similar actions.

k) In order to encourage participation in the Scheme, a subsidy can be paid corresponding to the premium paid for each call option. This subsidy shall in that case be paid during September 2028.

l) The company has the right to repurchase the call options by the holder if the holder does not wish to use all acquired call options and has notified the Company about this. Acquisition of options shall occur at a price which at the time was equivalent to no more than the market value. Repurchase of call options cannot be made during such period when trading with shares in the Company is prohibited by Article 19 of the European Parliament and Council Regulation (EU) No 596/2014 of 16 April 2014 on market abuse (market abuse regulation), or the prevailing corresponding legislation.

m) The Board of Directors shall, within the framework of the above conditions and policies be responsible for the preparation and management of the Scheme.

The costs of the Scheme consist of the subsidy paid during September 2028 as detailed above and the social security charges payable on this subsidy. The total cost of the subsidy, including social security charges, has been estimated to approximately MSEK 51 after corporate tax (calculated based on the prevailing market conditions on 1 July 2026). Against this subsidy, the option premium corresponds to a total of approximately MSEK 49 which the Company will receive on transferring the call options (calculated based on the prevailing market conditions on 1 July 2026), as a result of which the Scheme will not involve any material net charge to the Company's equity.

The reason for deviation from the shareholders' preferential rights and the Board of Directors' reasons for carrying out this Scheme is that senior management within the Addtech Group should be able to benefit from and strive for, through their own investment, an increase in the price of the Company's shares, thus more closely aligning the interests of senior managers and the Company's shareholders. The purpose of the Scheme is also to contribute towards management personnel increasing their long-term shareholdings in the Company. The Scheme is also expected to create conditions for retaining and recruiting competent personnel for the Addtech Group, to provide competitive remuneration and to align the interests of the shareholders and management. The members of management included in the Scheme are the group that, in an otherwise heavily decentralized organization, can create positive effects through cooperation between the Group's subsidiaries. On the basis of this, the Board of Directors believes that the introduction of the Scheme will have a positive effect on the continued development of the Addtech Group, and that the Scheme will benefit both the shareholders and the Company.

The Company has three long-term incentive schemes since earlier, the 2023, 2024 and 2025 Share Related Incentive Schemes.

In the Share-based Incentive Scheme of 2023, there are a total of 674,500 outstanding call options, which entitles the acquisition of an equivalent number of shares of class B in the Company. The exercise price for these call options was set at SEK 221.00 per share and the exercise period covers the time from 7 September 2026 to 9 June 2027.

In the Share-based Incentive Scheme of 2024, there are a total of 639,925 outstanding call options, which entitles the acquisition of an equivalent number of shares of class B in the Company. The

Page 7 (10)

^{}[] This is a translation of the Swedish original. In case of any discrepancies between this translation and the Swedish original, the latter shall prevail.

^{}[] ADDTECH

exercise price for these call options was set at SEK 388.80 per share and the exercise period covers the time from 6 September 2027 to 9 June 2028.

In the Share-based Incentive Scheme of 2025, there are a total of 761 575 outstanding call options, which entitles the acquisition of an equivalent number of shares of class B in the Company. The exercise price for these call options was set at SEK 392.70 per share and the exercise period covers the time from 5 September 2028 to 8 June 2029.

All underlying ca 2,100,000 shares of class B in the Company of outstanding options correspond in their entirety to the already repurchased class B shares in the Company.

The resolution proposed by the Board of Directors in accordance with item 16 must be approved by shareholders representing not less than nine tenths of the votes cast and shares represented at the Annual General Meeting.

17. Resolution regarding authorisation for the Board of Directors to decide on the purchase and transfer of own shares

The Board of Directors proposes that the Annual General Meeting passes a resolution authorising the Board of Directors to decide – during the period until the next Annual General Meeting – to acquire a maximum number of class B shares so that the Company's holding of own shares at any given time does not exceed 10 percent of the total number of shares outstanding in the Company. Acquisitions shall be made on Nasdaq Stockholm in accordance with the exchange's rules and may not be carried out at a price higher than the higher of the price of the most recent independent trade and the highest current independent bid on the trading venue where the acquisition is executed. Acquisitions may not be made at a price lower than the lowest price at which an independent acquisition can be carried out. Acquisitions shall be paid for in cash and may be made on one or more occasions.

The Board of Directors further proposes that the Annual General Meeting authorises the Board of Directors – during the period until the next Annual General Meeting – to sell its own shares in ways other than on Nasdaq Stockholm. The authorisation may be exercised on one or more occasions and covers all shares held by the Company at the time of the decision of the Board of Directors. The authorisation includes the right to decide to deviate from shareholders' preferential rights and that payment may be effected in forms other than money.

The purpose of the authorisation is to adapt the Group's capital structure and to enable companies or business operations to be acquired in the future through payment with own shares. The holding of own shares also safeguards the Company's obligations under the share-based incentive Scheme resolved at the Annual General Meeting in 2023, 2024 and 2025 and the Share-Related Incentive Scheme proposed under item 16 above.

The resolution proposed by the Board of Directors in accordance with item 17, must be approved by shareholders representing not less than two thirds of the votes cast and shares represented at the Annual General Meeting.

18. Resolution regarding authorisation for the Board of Directors to resolve on a new issue of up to 5 percent of the number of B-shares as means of payment during acquisitions

Page 8 (10)

^{}[] ADDTECH

With the purpose of enabling more company acquisitions, the board of directors proposes that the Annual General Meeting resolve to authorise the board of directors – during the period until the next following Annual General Meeting – to decide on the issue of new shares, on one or more occasions, in deviation from shareholders' preferential rights, against payment in cash, by set-off or with non-cash consideration. However, such issues may not cause the Company's registered share capital or the number of shares in the Company to increase by more than a total of 5 percent, based on the Company's registered share capital or the number of shares prior to exercise of the authorisation. Set-off shall only be possible against claims in connection with payment for shares in companies acquired by the Company. Issues shall take place on market-related terms and conditions.

The board, the managing director or the person that the board appoints, shall have the right to make any adjustments to the decision required for registration.

The resolution proposed by the board of directors in accordance with item 18 must be approved by shareholders representing not less than two thirds of the votes cast and shares represented at the Annual General Meeting.

The total number of votes, after deduction of the shares the Company holds, is 385,858,482. This information relates to the situation at the time of issuing this notice.

SHAREHOLDERS RIGHT TO REQUEST INFORMATION

Pursuant to Chapter 7, section 32 and 57 of the Swedish Companies Act (Sw. aktiebolagslagen), the Board of Directors and the managing director are under a duty to, if any shareholder so requests and the Board of Directors deems that it can be made without material damage to the company, provide information at the Annual General Meeting, regarding circumstances which may affect the assessment of a matter on the agenda or the company's economic situation.
