PROPOSED RESOLUTIONS

Prior to the Annual General Meeting 2026, Addnode Group’s Nomination Committee has consisted of Jonas Gejer (the Chairman of the Nomination Committee), appointed by Aretro Capital Group AB, Claes Murander, appointed by Lannebo Kapitalförvaltning, Celia Grip, appointed by Swedbank Robur Fonder, Johanna Ahlqvist, appointed by Cliens Kapitalförvaltning, and Staffan Hanstorp, Chairman of Addnode Group’s Board. The Nomination Committee of Addnode Group has submitted proposals for resolution under item 2, 14-16 and 23 on the agenda. The Board has submitted proposals under item 10, 12 and 17-22 on the agenda.

Item 2 - Election of Chairman of the Meeting
The Nomination Committee proposes Staffan Hanstorp, Chairman of the Board, to be elected as Chairman of the Meeting.

Item 10 - Decision regarding the disposition of the company's profits in accordance with the adopted balance sheet and the record date if the Meeting resolves on a dividend

The Board proposes a dividend of SEK 1.15 per share and Monday 11 May 2026 as the record date for the dividend. Based on this record date, Euroclear Sweden is expected to pay out the dividend on 15 May 2026. The proposal means that SEK 155,888,724 is paid to the shareholders and that the remaining disposable profit amounting to SEK 1,050,629,693 is carried forward.

Item 12 - Presentation of remuneration report for approval

The Board proposes that the Meeting approves the report regarding remuneration to the CEO and the Board for the financial year 2025.

Item 14 and 16 - Determination of the number of Board members and election of Board members, Chairman of the Board and auditor

The Nomination Committee proposes the Board to consist of seven members and to re-elect the Board members Jan Andersson, Jonas Gejer, Staffan Hanstorp, Jonas Hasselberg, Kristina Willgård and Petra Ålund and to elect Malin Stråhle as new Board member. Johanna Frelin has declined re-election. Staffan Hanstorp is proposed as the Chairman of the Board. No deputies shall be elected to the Board.

The Nomination Committee proposes, in accordance with the recommendation from the Audit Committee, election of the registered accounting firm Ernst & Young AB as auditor for the period until the end of the next Annual General Meeting. Ernst & Young AB will appoint Anna Svanberg as auditor in charge.

Item 15 – Determination of remuneration to the Chairman of the Board, the other Board members, and to the auditor

The Nomination Committee has carried out a comparison with relevant peer companies and notes that current remuneration levels are below the median. To ensure that remuneration is in line with the market, an increase in Board remuneration is therefore proposed. The Nomination Committee further proposes that the remuneration be reallocated to the Chairman of the Board whereby the maximum remuneration under the special agreement be reduced, whilst the ordinary remuneration is increased by a corresponding amount.

The Nomination Committee proposes fees to the Board, for the period until the end of the next Annual General Meeting, to be paid in the amounts of SEK 1,000,000 (previously SEK 640,000) to the Chairman of the Board and SEK 360,000 (previously SEK 320,000) to each of the other Board members elected by the Annual General Meeting. Remuneration may further be paid on account for special undertakings by Board members in their respective fields of expertise (consultancy services etc.), provided that such undertakings have previously been approved by the Chairman of the Board or by two Board members. Furthermore, fees for work in the Audit Committee shall be paid in the amount of SEK 180,000 (previously SEK 175,000) to the Chairman of the Committee and SEK 135,000 (previously SEK 130,000) to each of the other committee members. Fees for work in the Remuneration Committee shall be paid in the amount of SEK 75,000 (previously SEK 70,000) to each of the committee members.

It is further proposed that a maximum of SEK 150,000 plus social security contributions (previously SEK 180,000) per month may be paid to the Chairman of the Board for work in relation to the Group's acquisition opportunities, funding, strategic partnerships and overall strategic matters as specifically agreed.

The Nomination Committee has also proposed that the auditors be paid a reasonable amount according to approved invoices.
The Nomination Committee considers it positive that Board members hold shares equivalent to one year’s remuneration. The Nomination Committee therefore proposes that the Board adopts a policy whereby Board members who do not yet hold such a stake in Addnode shares are expected, over a five-year period, to acquire Addnode shares with a total market value equivalent to at least one year’s Board remuneration before tax.

Item 17 - The Board’s proposal for a decision regarding guidelines for remuneration to the Executive Management

Executive Management means the CEO of the parent company and the other members of the group management. The guidelines are applicable to remuneration agreed, and amendments to remuneration already agreed, after adoption of the guidelines by the Annual General Meeting 2026. These guidelines do not apply to remuneration decided by the general meeting.

The guidelines’ promotion of the company’s business strategy, long-term interests and sustainability

The strategy of Addnode Group is to acquire, operate and develop entrepreneur-driven companies that help digitalise society. For further information regarding the company’s business strategy and its long-term financial targets, please refer to www.addnodegroup.com.

A prerequisite for the successful implementation of the company’s business strategy and safeguarding of its long-term interests, including its sustainability, is that the company is able to recruit and retain qualified personnel. The company shall therefore apply compensation levels and employment conditions that are competitive and on market terms to be able to recruit and retain a management with high competence and capacity to achieve set goals.

Types of remuneration, etc.

Remuneration to the CEO of the parent company and the other members of the Executive Management shall normally consist of fixed salary, variable remuneration, share based incentive plans, pension and additional benefits.

Fixed salary

To obtain fixed salary, no achievement of specific performance targets is required. However, the employee’s individual results and qualitative competence shall be taken into account together with the business result when determining fixed salaries and possible salary increases. The fixed salary is as a general rule re-evaluated on an annual basis.

Variable cash remuneration

A variable remuneration can be paid in addition to the fixed salary. Variable remuneration shall be based on results achieved and/or individually established and specific targets. The variable remuneration shall be based on measurements that are linked to the annual business plan, which in turn is linked to Addnode Group's long-term business strategy and financial targets. The measurements shall include financial targets on group level and division level (for relevant members of the Executive Management). Other measurements can be strategic targets, operational targets, targets for co-worker commitment or customer satisfaction, targets related to sustainability and responsible business or other leading indicators. The starting point is that the majority of the variable remuneration shall be based on the measurements for the part of the business that the senior executive is responsible for.

In total, a maximum of four targets can be assigned to a member of the Executive Management for a financial year. Financial targets shall stand for at least 75 per cent of possible target bonus, and at least 15 per cent shall be on group level. The minimum weighting for an individual target shall be 10 per cent. The result for all targets shall be calculated on a result period of 12 months (financial year). For the President/CEO the maximum payment of variable remuneration amounts to the equivalent of twelve fixed monthly salaries. For other members of the Executive Management, the maximum payment is nine fixed monthly salaries.

Share based incentive plans

Share based incentive plans shall secure a long-term commitment to the Group's development and encourage own shareholding in the company as well as be implemented on market terms. Share based incentive plans shall be resolved by the general meeting and are therefore not covered by these guidelines.

Pensions and other benefits

Pensions shall always be premium based to create predictability with regards to the company's future commitments. Pension premiums shall be paid with up to a maximum of 30 per cent of the current fixed annual salary.

Other remuneration and benefits shall be on market terms and contribute to facilitating the executive's ability to carry out his/her work assignments and may not amount to more than 10 per cent of the fixed annual cash salary. Other benefits mainly refer to company car or car allowance.

Termination of employment

The employment contracts of the senior executives include terms regulating termination of employment. According to the policy, employment can be terminated at the request of one party, with a term of notice of at least six months and a maximum of twelve months. During the term of notice, the payment of salaries, remuneration and benefits shall be unchanged.

Salary and employment conditions for employees

In the preparation of the Board’s proposal for these remuneration guidelines, salary and employment conditions for employees of the company have been taken into account by including information on the employees’ total remuneration, the components of the remuneration and increase and growth rate over time, in the Remuneration Committee’s and the Board’s basis of decision when evaluating whether the guidelines and the limitations set out herein are reasonable.

Remuneration to the Board in addition to fees resolved by the general meeting

Members of the Board elected by the general meeting shall in special cases be able to receive fees and other remuneration for work performed on behalf of the company in addition to the work on the Board (consultancy services etc within the Board members' respective fields of expertise). For such services, fees shall be paid on market terms and shall be approved in advance by the Chairman of the Board or by two members of the Board. These guidelines apply to such remuneration.

The decision-making process to determine, review and implement the guidelines

The Board has established a Remuneration Committee. The committee’s tasks include preparing the Board’s decision to propose guidelines for executive remuneration and any decision to deviate from the guidelines. The Board shall prepare a proposal for new guidelines at least every fourth year and submit it to the Annual General Meeting. The guidelines shall be in force until new guidelines are adopted by the general meeting. The Remuneration Committee shall also monitor and evaluate programs for variable remuneration for the Executive Management, the application of the guidelines for executive remuneration as well as the current remuneration structures and compensation levels in the company. The CEO and other members of the Executive Management do not participate in the Board’s processing of and resolutions regarding remuneration-related matters insofar as the matters concern their own remuneration.

Derogation from the guidelines

The Board may temporarily resolve to derogate from the guidelines, in whole or in part, if in a specific case there is special cause for the derogation and a derogation is necessary to serve the company’s long-term interests, including its sustainability, or to ensure the company’s financial viability. If the Board derogates from the guidelines for remuneration for the Executive Management, this shall be reported in the remuneration report before the next Annual General Meeting.

Description of changes to the guidelines, etc.

The Board has not received any comments from the shareholders on the existing guidelines for remuneration to the Executive Management. The company’s long-term financial targets presented in the guidelines have been removed and a reference to the company’s website has been added. Apart from this, no changes have been made to the guidelines and the Board’s proposal corresponds in all material respects to the existing guidelines.

Item 18 - The Board’s proposal for a decision on A) long-term performance share based incentive plan (LTIP 2026) and B) transfer of own class B shares under LTIP 2026

The Board proposes that the Annual General Meeting resolves on a long-term performance share based incentive plan (LTIP 2026) for Addnode Group in accordance with item A) below and on transfer of own class B shares under LTIP 2026 in accordance with item B) below.

A) DECISION ON LONG-TERM PERFORMANCE SHARE BASED INCENTIVE PLAN

LTIP 2026 in brief

The primary reason for implementing LTIP 2026 is to align the interests of the shareholders with the interests of the Executive Management and other key employees to ensure maximum long-term value creation. LTIP 2026 is also considered to facilitate Addnode Group’s recruitment and retention of senior executives and other key positions. LTIP 2026 comprises approximately 125 employees consisting of senior executives and other key employees. The participants are allocated performance based share rights, which may entitle the participant to class B shares. Following the defined vesting period, the participants will, free of charge, be allocated class B shares in Addnode Group provided that certain performance targets are fulfilled. A prerequisite for allocation of class B shares is that the participant, with certain limited exceptions, remain employed within the Addnode Group. In addition, it is required that Addnode Group's earnings per share amounted to at least certain levels and that the total shareholder return (TSR)^[1] on the class B shares in Addnode Group on Nasdaq Stockholm has been positive. The maximum number of class B shares in Addnode Group, which may be allocated in total under the LTIP 2026 shall be limited to 145,000, which corresponds to approximately 0.1 per cent of all outstanding shares in Addnode Group.

Participants in LTIP 2026

LTIP 2026 comprises up to 125 employees with management positions in the Addnode Group, who have a direct opportunity to influence the Group's results. The number of share rights that the employee is allocated shall depend on the employee's responsibilities and position and be divided into five categories. Category A comprises the CEO of Addnode Group, category B comprises the other members of Addnode Group’s Executive Management (approximately 5 persons) and category C - E comprises for example CEOs of subsidiaries, as well as performance managers and management functions in major subsidiaries (approximately 119 persons). The Board shall finalise the categorisation on the basis of the employee's responsibilities and position.

People that have been recruited, but not yet started their employment with Addnode Group when the notification of participation in the plan has to take place, can be offered participation provided that their employment starts, and share rights are allotted, no later than 30 September 2026.

Number of share rights and vesting period

The number of share rights that a participant can be allocated depends on which category the participant belongs to. The participant in category A can be allocated 10,000 share rights (with a maximum of 10,000 class B shares as outcome), participants in category B can be allocated 5,500 share rights (with a maximum of 5,500 class B shares as outcome per individual), participants in category C-E can be allocated 3,000 share rights (with a maximum of 3,000 class B shares as outcome per individual). The Board shall determine the allocation of share rights per category. Allocation of class B shares in Addnode Group, if any, based on share rights shall normally occur within ten business days after the announcement of Addnode Group’s interim report for the period 1 January - 31 March 2029. The vesting period begins when an agreement is entered into to participate in LTIP 2026 and expires in connection with the publication of Addnode Group's interim report for the period 1 January - 31 March 2029.

Terms for the share rights

The following conditions shall apply for the share rights:

• The share rights are allocated free of charge a certain time after the Annual General Meeting.
• The share rights may not be transferred or pledged.
• The right to receive allocation of class B shares based on share rights requires, with certain limited exceptions, that the participant remains employed within the Addnode Group during the vesting period. Allocation also requires that performance targets are fulfilled as described under “Performance Targets” below.
• Addnode Group will not compensate the participants in LTIP 2026 for ordinary dividends paid in respect of the shares that the respective share right entitles to.

Performance targets

The performance target that has to be achieved or exceeded relates to average annual growth of the company’s earnings per share during the financial years 2026-2028 (the “Measurement Period”). The minimum level of allocation is an average annual growth of the company's earnings per share during the Measurement Period of 2 per cent and the maximum level of allocation is an average annual growth during the Measurement Period of 12 per cent. Allocation of class B shares falls out linearly in the interval between 2-12 per cent. Through the link to earnings per share throughout the Measurement Period, the performance targets contribute to Addnode Group's long-term value creation.

Allocation of class B shares further requires that the total shareholder return (TSR) on the company's class B shares during the term of the programme has been positive. In this calculation, the TSR development shall be based on a comparison of the volume-weighted average price paid for the company's class B shares on Nasdaq Stockholm during a period of ten trading days, where (i) the start value is calculated during the period beginning the day after the Annual General Meeting 2026 and (ii) the end value is calculated during the period beginning the day after the publication of Addnode Group's interim report for the period 1 January - 31 March 2029.

Formulation and administration

The Board shall be entitled to resolve on the detailed terms for the execution of LTIP 2026. The Board shall thereby be entitled to make minor adjustments in the Annual General Meeting’s resolution if the Board considers there to be special reasons in an individual case. The Board shall also be entitled to make adjustments to fulfil specific regulations or market conditions in other jurisdictions or, if delivery of shares to participants outside Sweden cannot be made at reasonable costs and with reasonable administrative efforts, to make country specific adjustments and/or offer cash settlement. If material changes occur in the Addnode Group or in its business environment that would entail that the decided terms for allocation and the possibility to exercise the share rights in accordance with LTIP 2026 no longer are appropriate, the Board shall be entitled to make other adjustments. Before finally determining the number of shares to be allocated based on the share rights, the Board shall assess whether the outcome of LTIP 2026 is reasonable. This assessment is made in relation to Addnode Group’s financial earnings and financial position, conditions on the stock market and other circumstances. If the Board is of the opinion that the outcome is not reasonable, the Board shall reduce the number of shares to be allocated.

Scope

The maximum number of class B shares in Addnode Group which may be allocated under LTIP 2026 shall be limited to 145,000, which represents approximately 0.1 per cent of all outstanding shares in Addnode Group. In accordance with the detailed conditions that the Board stipulates, the number of shares included in LTIP 2026 shall be subject to recalculation if Addnode Group implements a bonus issue, a reversed share split or a share split, a rights issue, an extraordinary dividend or similar corporate actions taking into account customary practice for similar incentive plans.

Hedging

The Board has considered two alternative hedging methods for the LTIP 2026; either a hedging arrangement (equity swap) with a bank for securing delivery of class B shares under the plan or transfer of class B shares in Addnode Group to entitled participants in the LTIP 2026. The Board considers the latter alternative to be preferable. The Board has therefore proposed that the Annual General Meeting shall resolve on transfer of class B shares in Addnode Group, which are held by the company (see item B) below) as well as to authorise the Board to execute acquisition of class B shares in Addnode Group (see item 21 in the agenda). Should the Annual General Meeting, however, not approve the Board’s proposal, the Board may enter into the hedging arrangement described above with a bank to secure the obligation of the company to deliver class B shares under the plan. Such a hedging arrangement with a bank may also be used for the purpose to cash flow wise cover social security contributions that arise as a result of the LTIP 2026.

Costs and value

The share rights cannot be pledged or transferred to others. Based on the assumptions of a share price for Addnode Group's class B share of SEK 67, all employees who have been offered participation in the plan participate, 100 per cent fulfilment of the performance targets and a employee turnover of 10 per cent as well as an increase of the share price of 50 per cent for the duration of the programme, it is estimated that the total cost of LTIP 2026, including social security costs, will amount to approximately SEK 8.7 million before tax (approximately SEK 2.9 million per year). On an annual basis, the total cost for LTIP 2026 is estimated to amount to approximately 0,10 per cent of Addnode Group’s total staff costs, excluding costs for long-term incentive programs, based on planned staffing during the financial year 2026.

The costs are treated as staff costs in the profit and loss accounts during the vesting period, in accordance with IFRS 2 on share-based payments and is based on the share price at the start of the program. In the profit and loss accounts, social security costs will accrue in accordance with UFR 7 over the vesting period. The size of these costs will be calculated based on Addnode Group’s share price development during the vesting period and allocation of the share rights.

The preparation of the proposal

LTIP 2026 has been prepared in consultation with external advisors and processed with the Remuneration Committee and at Board Meetings during the spring 2026.

Other incentive plans in Addnode Group

Please refer to Addnode Group’s annual report 2025, note 4 and 5 or Addnode Group’s website, www.addnodegroup.com, for a description of other share-based incentive plans that are still outstanding in Addnode Group.

The proposal by the Board

Referring to the description above, the Board proposes that the Annual General Meeting resolves on LTIP 2026.

Majority requirements

A valid resolution under this item A) requires that the resolution is supported by shareholders holding more than half of the votes cast at the Annual General Meeting.

B) DECISION ON TRANSFER OF OWN CLASS B SHARES UNDER LTIP 2026

The Board’s proposal on a resolution to transfer class B shares in Addnode Group as set out below, provides that the Annual General Meeting first has resolved on a long-term performance share based incentive plan (LTIP 2026) in accordance with item A) above.

Transfer of class B shares in Addnode Group to participants in the LTIP 2026

The Board proposes that the Annual General Meeting resolves to transfer class B shares in the company in accordance with the following.

• Not more than 145,000 class B shares in Addnode Group may be transferred (or the higher number of class B shares due to recalculation as a result of a bonus issue, a reversed share split or a share split, rights issue, compensation for extraordinary dividends or similar actions).
• The class B shares may be transferred to participants in the LTIP 2026 who under the terms for the LTIP 2026 are entitled to receive class B shares.
• Transfer of class B shares shall be made at the time and otherwise according to the terms pursuant to the LTIP 2026.

The reason for deviating from the shareholders' preferential rights is that the transfer of class B shares is part of the execution of the LTIP 2026. Therefore, the Board considers the transfer of class B shares in accordance with the proposal to benefit the company.

Majority requirements

A valid decision under this item B) requires that the decision is supported by shareholders representing at least nine tenths of both the votes cast and the shares represented at the general meeting.

Item 19 - The Board’s proposal for a decision on a repurchase and set-off offer regarding call options (LTIP 2022), including (A) approval of conditional offer to repurchase call options and (B) approval of transfer of class B shares

BACKGROUND TO THE PROPOSAL

At the Annual General Meeting in Addnode Group held on 4 May 2022, it was resolved to issue call options as part of the establishment of an incentive program for senior executives of the Addnode Group (“LTIP 2022”). After the initial two exercise periods for LTIP 2022 have expired, 56,950 call options (the "Call Options") remain outstanding, which are held by a total of 42 option holders (the “Option Holders”) at the time of the notice convening the Annual General Meeting.

The Call Options may, under the terms of the Call Options, be exercised to acquire four (4) repurchased class B shares^[2] in Addnode Group per Call Option from the day after the publication of the interim report for the period 1 January-31 March 2026, but no earlier than 25 April 2026, up to and including 10 June 2026.

Addnode Group has 997,262 class B shares held in treasury, which were previously acquired for the purpose of enabling delivery of shares in connection with the implementation of the company's long-term share-related incentive programmes. The Board of Addnode Group now proposes that, in connection with the last exercise period for LTIP 2022, the company shall make an offer to the Option Holders to transfer all held Call Options to the company at a price corresponding to the net value (see-through value) that the Call Options would have resulted in for the Option Holders if the Call Options had been exercised at that time (the "Call Option Value"), and where consideration for the Call Options is paid in the form of class B shares in Addnode Group (the "Offer"). The company's interim report for the period 1 January-31 March 2026 is intended to be published on 28 April 2026.

By participating in the Offer, which is voluntary, the Option Holders’ need to finance payment of the Call Options’ exercise price by, for example, selling shares in Addnode Group is reduced, facilitating the exercise of the Call Options. For Addnode Group, the Offer means that the company will not receive an exercise price upon exercise of the Call Options and that a lower number of shares in Addnode Group are transferred to the participants compared to when the Call Options are exercised in accordance with the terms and conditions for the Call Options, as the shares issued as consideration in the Offer only correspond to the net value of the Call Options. The Offer is not intended to constitute any benefit to the Option Holders, but only to facilitate the Option Holders to realise the value of the Call Options without any financing requirement, which is deemed to be beneficial also to the shareholders of Addnode Group.

To illustrate the effects of the Offer at different share prices of the Addnode Group’s class B share at the time of valuation, an illustrative calculation example is provided below (based on that all Call Options are repurchased in the Offer and that all Call Options are exercised in accordance with the terms and conditions for the Call Options).

The Offer is assessed not to entail any additional tax costs nor transaction fees for the company. The repurchase transaction is not expected to entail any significant effects on Addnode Group’s results or equity, considering that the Offer is conditional upon the Board finding that conditions exist for the claim for consideration that arises for the participants in connection with the acceptance of the Offer to be used as a set-off payment for the class B shares to be transferred. Addnode Group will thus not pay any cash consideration for the Call Options (other than for any excess claims for consideration that could not be used for set-off), with the result that available earnings will not be affected.

The proposal under this item has been prepared by the Board and its remuneration committee.

A) APPROVAL OF CONDITIONAL OFFER TO REPURCHASE CALL OPTIONS

The Board of Addnode Group proposes that the Annual General Meeting resolves to approve that Addnode Group submits the Offer to the Option Holders on the terms and conditions set out below.

• A maximum of 56,950 Call Options 2022/2026, i.e. the Call Options outstanding under Addnode Group’s LTIP 2022 shall be eligible for repurchase.
• The repurchase shall be made at the Call Option Value, based on the volume-weighted average price paid for Addnode Group's class B share on Nasdaq Stockholm during the five trading days preceding the acceptance period for the Offer (the company’s interim report for the period 1 January-31 March 2026 is intended to be published on 28 April 2026). The calculation of the Call Option Value shall be performed by an independent party.

Of the 56,950 outstanding Call Options, 5,000 are held by Addnode Group’s CEO.

The Offer shall be conditional upon (i) that the Meeting resolves to approve the Board’s resolution on the transfer of class B shares in accordance with item B) below and that (ii) the Board finds that conditions exist for the claim for consideration that arises for the participants in connection with the acceptance of the Offer to be used as set-off payment for the class B shares that are transferred in accordance with item B) below. The condition set forth in (ii) above is expected to be fulfilled on Friday 8 May 2026, after which the acceptance period for the Offer is intended to last until the start of trading in Addnode Group's shares on Monday 11 May 2026. Addnode Group does not intend to provide any cash consideration for the Call Options other than for any excess claim for consideration that cannot be used as a set-off. The Call Options repurchased by Addnode Group will be cancelled.

Option Holders who do not accept the Offer may, without being affected by the Offer, exercise their Call Options for acquisition of class B shares during the last acquisition period in accordance with the terms and conditions applicable to the Call Options.

B) APPROVAL OF TRANSFER OF CLASS B SHARES

The Board of Addnode Group proposes that the Annual General Meeting resolves to approve transfer of class B shares, which Addnode Group holds in treasury, on the terms and conditions set out below (the “Transfer”).

Through the Transfer, a maximum of 100,000 class B shares shall be transferred. As stated above, the intention is that the class B shares will be transferred as part of the implementation of a repurchase and set-off offer, which is why the number of class B shares finally transferred and allocated is intended to be determined on the basis of the number of Call Options submitted in the Offer and the Call Option Value and the market value of the company’s class B share (see below under “Transfer price”). The Transfer shall be conditional upon the Board declaring the Offer under item A) above to be unconditional. The condition is expected to be fulfilled on Friday 8 May 2026, and agreement regarding the Transfer shall be entered into before trading in Addnode Group's shares commences on Monday 11 May 2026. The Board shall be entitled to extend the acquisition period and the time for payment. Otherwise, the following terms and conditions shall apply to the Transfer:

Transfer price
Each class B share shall be transferred at a transfer price corresponding to the market value of the class B share (however, never lower than the quotient value of the share), based on the volume-weighted average price paid for Addnode Group's class B share on Nasdaq Stockholm during the five trading days preceding the acceptance period for the Offer (the company’s interim report for the period 1 January-31 March 2026 is intended to be published on 28 April 2026). The transfer price for the transferred class B shares will be paid by using the claim for consideration that arises for the participants in connection with the acceptance of the Offer, used as a set-off, which shall take place at the latest before trading in Addnode Group's shares begins on Monday 11 May 2026.

Right to participate in the Transfer
The right to participate in the Transfer shall be granted to the Option Holders who have accepted the Offer during the acceptance period. The purpose is to be able to implement the repurchase and set-off offer, which is deemed to be beneficial to the company and the Option Holders.

Majority requirements
A valid decision under this item A) requires that the decision is supported by shareholders representing at least nine tenths of both the votes cast and the shares represented at the general meeting. Items A) and B) are conditional upon each other and shall be resolved as a joint decision.

Item 20 - The Board’s proposal for a decision on a repurchase and set-off offer regarding call options (LTIP 2023), including (A) approval of conditional offer to repurchase call options and (B) approval of transfer of class B shares

BACKGROUND TO THE PROPOSAL

At the Annual General Meeting in Addnode Group held on 4 May 2023, it was resolved to issue call options as part of the establishment of an incentive program for senior executives of the Addnode Group (“LTIP 2023”). The LTIP 2023 comprises a total of 201,000 call options (the "Call Options"), which are held by a total of 42 option holders (the “Option Holders”) at the time of the notice convening the Annual General Meeting.

The Call Options may, under the terms of the Call Options, be exercised to acquire one (1) repurchased class B share in Addnode Group per Call Option during the following periods:

• i) from the day after the publication of the interim report for the period 1 July-30 September 2026, but no earlier than 25 October 2026 up and until 10 December 2026,
• ii) from the day after publication of the year-end report for the period 1 January-31 December 2026, but no earlier than 25 January 2027, up to and including 10 March 2027, and
• iii) from the day after publication of the interim report for the period 1 January-31 March 2027, but no earlier than 25 April 2027, up to and including 10 June 2027.

Addnode Group has 997,262 class B shares held in treasury, which were previously acquired for the purpose of enabling delivery of shares in connection with the implementation of the company's long-term share-related incentive programmes. The Board of Addnode Group now proposes that the company, in connection with each exercise period for LTIP 2023, shall make an offer to the Option Holders to transfer all held Call Options to the company at a price corresponding to the net value (see-through value) that the Call Options would have resulted in for the Option Holders if the Call Options had been exercised at that time (the "Call Option Value"), and where consideration for the Call Options is paid in the form of class B shares in Addnode Group ("Offer 2023:1", "Offer 2023:2", and "Offer 2023:3", respectively).

By participating in Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, which are voluntary, the Option Holders’ need to finance payment of the Call Options’ exercise price by, for example, selling shares in Addnode Group is reduced, facilitating the exercise of the Call Options. For Addnode Group, Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, mean that the company will not receive an exercise price upon exercise of the Call Options and that a lower number of shares in Addnode Group are transferred to the participants compared to when the Call Options are exercised in accordance with the terms and conditions for the Call Options, as the shares issued as consideration in Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, only correspond to the net value of the Call Options. Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, are not intended to constitute any benefit to the Option Holders, but only to facilitate the Option Holders to realise the value of the Call Options without any financing requirement, which is deemed to be beneficial also to the shareholders of Addnode Group.

To illustrate the effects of Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, at different share prices of the Addnode Group’s class B share at the time of valuation, an illustrative calculation example is provided below (based on that all Call Options are repurchased in Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, and that all Call Options are exercised in accordance with the terms and conditions for the Call Options).

Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, are not expected to entail any additional tax costs or transaction fees for the company. The repurchase transaction is not expected to entail any significant effects on Addnode Group’s results or equity, considering that Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively are conditional upon the Board finding that conditions exist for the claim for consideration that arises for the participants in connection with the acceptance of Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, to be used as a set-off payment for the class B shares to be transferred. Addnode Group will thus not pay any cash consideration for the Call Options (other than for any excess claims for consideration that could not be used for set-off), with the result that available earnings will not be affected.

The proposal under this item has been prepared by the Board and its remuneration committee.

A) APPROVAL OF CONDITIONAL OFFER TO REPURCHASE CALL OPTIONS

The Board of Addnode Group proposes that the Annual General Meeting resolves to approve that Addnode Group submits Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, to the Option Holders on the terms and conditions set out below.

• A maximum of 201,000 Call Options 2023/2027, i. e. the Call Options outstanding under Addnode Group’s LTIP 2023 shall be eligible for repurchase.
• Repurchase shall be made at the Call Option Value, based on the volume-weighted average price paid for Addnode Group's class B share on Nasdaq Stockholm during the five trading days following the day after (i) publication of the company's interim report for the period 1 January-30 September 2026, which is intended to be published on 23 October 2026, (ii) publication of the company's interim report for the period 1 January-31 December 2026, which is intended to be published on 9 February 2027, and (iii) publication of the company's interim report for the period 1 January-31 March 2027, which is intended to be published on 27 April 2027, and which precede the acceptance periods for Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively. The calculation of the Call Option Value shall be performed by an independent party.

Of the 201,000 outstanding Call Options, 20,000 are held by Addnode Group’s CEO.

Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, shall be conditional upon (a) that the Meeting resolves to approve the Board’s resolution on the transfer of class B shares in accordance with item B) below and that (b) the Board finds that conditions exist for the claim for consideration that arises for the participants in connection with the acceptance of Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, to be used as set-off payment for the class B shares that are transferred in accordance with item B) below. The condition set forth in (b) above is expected to be fulfilled on (i) Friday 30 October 2026, after which the acceptance period for Offer 2023:1 is intended to run until the start of trading in Addnode Group's shares on Monday 2 November 2026, (ii) Tuesday 16 February 2027, after which the acceptance period for Offer 2023:2 is intended to run until the start of trading in Addnode Group's shares on Wednesday 17 February 2027, and (iii) Tuesday 4 May 2027, after which the acceptance period for Offer 2023:3 is intended to run until the start of trading in Addnode Group's shares on Wednesday 5 May 2027. Addnode Group does not intend to provide any cash consideration for the Call Options other than for any excess claim for consideration that cannot be used as a set-off. The Call Options repurchased by Addnode Group will be cancelled.

Option Holders who do not accept Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, may, without being affected by the offers, exercise their Call Options for acquisition of class B shares during the acquisition periods in accordance with the terms and conditions applicable to the Call Options.

B) APPROVAL OF TRANSFER OF CLASS B SHARES

The Board of Addnode Group proposes that the Annual General Meeting resolves to approve transfer of class B shares, which Addnode Group holds in treasury, on the terms and conditions set out below (the “Transfer”).

Through the Transfer, a maximum of 100,000 class B shares shall be transferred. As stated above, the intention is that the class B shares shall be transferred as part of the implementation of repurchase and set-off offers, which is why the number of class B shares finally transferred and allocated is intended to be determined on the basis of the number of Call Options submitted in Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, and the Call Option Value and the market value of the company’s class B share (see below under “Transfer price”). The Transfer shall be conditional upon the Board declaring Offer 2023:1, Offer 2023:2 and Offer 2023:3 under item A) above unconditional. The condition is expected to be fulfilled on (i) Friday 30 October 2026, (ii) Tuesday 16 February 2027 and (iii) Tuesday 4 May 2027, respectively, and agreement regarding the Transfer shall be entered into before trading in Addnode Group's shares commences on (i) Monday 2 November 2026, (ii) Wednesday 17 February 2027 and (iii) Wednesday 5 May 2027, respectively. The Board shall be entitled to amend and extend the acquisition period and the time for payment for each respective period. Otherwise, the following terms and conditions shall apply to the Transfer:

Transfer price
Each class B share shall be transferred at a transfer price corresponding to the market value of the class B share (however, never lower than the quotient value of the share), based on the volume-weighted average price paid for Addnode Group's class B share on Nasdaq Stockholm during the five trading days following the day after the publication of the company's interim report for (i) the period 1 January-30 September 2026, which is intended to be published on 23 October 2026, (ii) the period 1 January-31 December 2026, which is intended to be published on 9 February 2027, and (iii) the period 1 January-31 March 2027, which is intended to be published on 27 April 2027, and which precede the acceptance period for Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively. The transfer price for the transferred class B shares will be paid by using the claim for consideration that arises for the participants in connection with the acceptance of Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively, used as a set-off, which shall take place at the latest before trading in Addnode Group's shares begins on (i) Monday 2 November 2026, (ii) Wednesday 17 February 2027 and (iii) Wednesday 5 May 2027, respectively.

Right to participate in the Transfer
The right to participate in the Transfer shall be granted to the Option Holders who have accepted Offer 2023:1, Offer 2023:2 and Offer 2023:3, respectively. The purpose is to be able to implement the repurchase and set-off offers, which is deemed to be beneficial to the company and the Option Holders.

Majority requirements
A valid decision under this item A) requires that the decision is supported by shareholders representing at least nine tenths of both the votes cast and the shares represented at the general meeting. Items A) and B) are conditional upon each other and shall be resolved as a joint decision.

Item 21 - The Board's proposal for a decision to authorize the Board to decide on acquisitions and transfer of own class B shares

The Board proposes that the Annual General Meeting authorizes the Board to, on one or several occasions prior to the next Annual General Meeting, decide to acquire a maximum number of class B shares so that the company at any given time following the acquisition holds a maximum of ten per cent of the total number of shares in the company. Repurchase shall be conducted on Nasdaq Stockholm and shall not be conducted at a price that exceeds the higher of the prices of the most recent independent trade and the highest current independent bid on Nasdaq Stockholm. Acquisitions may not be conducted at a price below the lowest possible market price. The company may assign a member of the stock exchange to accumulate a certain number of own shares by proprietary trading during a certain time period and on the day of delivery pay for the shares at a price corresponding to the volume-weighted average price based on the total trading during that period of time. The purpose of any repurchases of own shares is partly to be able to transfer shares in conjunction with financing of company acquisitions and other types of strategic investments, partly to be able to continuously adapt the company’s capital structure to its capital requirements from time to time, thereby contributing to increased shareholder value, as well as to enable the delivery of shares related to completion of the company's long-term share based incentive plans.

Furthermore, the Board proposes that the Annual General Meeting authorizes the Board to, on one or several occasions prior to the next Annual General Meeting, decide to transfer class B shares in the company to a third party. The number of shares transferred may not exceed the total number of shares held by the company at any time. Transfer may be conducted on or outside Nasdaq Stockholm and includes the right to deviate from the preferential rights of shareholders. The transfer of shares on Nasdaq Stockholm shall be conducted at a price within the registered price interval at any time. The transfer of shares outside Nasdaq Stockholm shall be made at a price in cash or value in property received that corresponds to the stock market price at the time of the transfer of Addnode Group shares that are transferred with the deviation that the Board deems appropriate. The reason for permitting the Board to deviate from the preferential rights of shareholders is to enable financing of potential company acquisitions and other types of strategic investments in a cost efficient manner, and to cover costs (including costs for social security contributions) arising from the implementation of Addnode Group's incentive programmes from time to time. For a valid decision under this item, the Annual General Meeting's decision must be supported by shareholders representing at least two thirds of both the votes cast and the shares represented at the Annual General Meeting.

Item 22 - The Board's proposal for a decision to authorize the Board to decide on issues of new class B shares

The Board proposes that the Annual General Meeting authorizes the Board to, on one or several occasions prior to the next Annual General Meeting, with or without deviation from the preferential rights of shareholders, decide on the issue of new class B shares. By resolution on the basis of the authorization, the number of class B shares may be increased by a maximum of ten per cent based on the number of outstanding class B shares at the time of the first use of the authorization. The authorization shall also include the right to decide on a new issue of class B shares with a provision for contribution in kind or that shares shall be subscribed for with a right of set‐off or otherwise with conditions stipulated in Chapter 13, Section 7 of the Swedish Companies Act. The reason for the deviation from the shareholders’ preferential rights is to enable directed issues for the execution of acquisitions of other companies or operations in full or in part. The basis for the issue price shall be the market value of the share. For a valid decision under this item, the Annual General Meeting's decision must be supported by shareholders representing at least two thirds of both the votes cast and the shares represented at the Annual General Meeting.

Item 23 - The Nomination Committee's proposal for Nomination Committee instructions

The Nomination Committee proposes that the Annual General Meeting instructs the Chairman of the Board to contact the four largest owner‐registered shareholders in terms of votes, based on shareholder statistics as per the last banking day in August, who each appoint one member to constitute the Nomination Committee along with the Chairman of the Board for the period until a new Nomination Committee is appointed by mandate of the next Annual General Meeting.

If one or more shareholders refrain from appointing a member of the Nomination Committee, one or more of the next largest shareholder in terms of votes shall be offered to appoint a member to the Nomination Committee. The Chairman of the Nomination Committee shall be the member appointed by the largest shareholder in terms of votes, if not agreed otherwise by the members of the Nomination Committee. The Chairman of the Board shall not be the Chairman of the Nomination Committee.

The composition of the Nomination Committee shall be announced as soon as it has been appointed and no later than six months before the upcoming Annual General Meeting. No fees shall be paid to the Nomination Committee, but the company shall pay for reasonable costs deemed necessary by the Nomination Committee in order for the Nomination Committee to be able to complete its assignment. If a member resigns from the Nomination Committee before completing his or her assignment, and if the Nomination Committee considers that there is a need to replace that member, the replacement shall be appointed by the same shareholder who appointed the resigning member. In the event that a significant change in the ownership structure occurs after the Nomination Committee has been formed, the composition of the Nomination Committee shall also be changed accordingly if the Nomination Committee deems it necessary. However, unless there are special circumstances, no changes shall be made to the composition of the Nomination Committee if the change occurs later than three months before the Annual General Meeting. Changes in the composition of the Nomination Committee shall be announced as soon as possible.

The task of the Nomination Committee shall be to submit proposals to the General Meeting regarding the number of Board members to be elected by the Meeting, Board fees, auditors' fees, any remuneration for committee work, the composition of the Board, the Chairman of the Board, the Nomination Committee, the Chairman of the General Meeting and election of auditors. The present Nomination Committee shall remain until the next Nomination Committee has been appointed.

These instructions for the Nomination Committee shall remain in force until the General Meeting resolves to amend them.
