      Adoption of the Strategy of Mabion S.A. for 2025-2030

      On 14 November 2025, following a review of its existing strategic assumptions, the Company's Management Board adopted a resolution on the adoption of a new Strategy for Mabion S.A. for the years 2025-2030 ("Strategy 2025-2030"﴿, and on 17 November 2025, in accordance with the requirement of §22(1﴿(h﴿ of the Articles of Association of Mabion S.A., a positive opinion was obtained from the Supervisory Board. Thus, the Strategy 2025-2030 was formally adopted for implementation.

      Mission

The newly appointed Advisory Board will contribute additional expertise, and the implementation of lean management solutions in operational management will enable an increase in plant productivity.

      Pillars of Strategy 2025-2030

      Mabion actively responds to market trends and changing customer needs by adapting its offer to current conditions. As a result of an analysis carried out by the company's new management board, strategic directions for the development of Mabion's offer were determined and the pillars for the implementation of this vision were defined.

      Three strategic pillars for the implementation of Mabion's vision:

      1. Technological advancement (pillar 1﴿

        • Development and production of biosimilars (mAb﴿,

        • Offering ADC development capabilities through strategic partnerships.

      2. Operational excellence and optimal scalability (pillar 2﴿

        • Implementation of projects in the field of highly potent/precision-handling biologics and vaccines segments -projects of complementary/tactical importance.

      Financial plan

      The implementation of the Strategy 2025-2030 is to be financed from equity, cash flows, as well as debt and EU grants. According to the adopted assumptions, the implementation of the Strategy 2025-2030 is expected to result in revenues in 2030 that are 1.5 times higher than the average for 2021-2025 (the average for 2021-2025 is over PLN 70 million annually﴿, with an EBITDA margin (EBITDA - Earnings Before Interest, Taxes, Depreciation and Amortization﴿ of over 30%.

      Mabion anticipates achieving EBITDA break-even by year-end 2026.

      ESG Strategy

      In parallel with the update of the Strategy 2025-2030, the Company also revised the existing assumptions of the ESG Strategy for 2025-2027. In order to align it with the current Company's business objectives the update of the ESG Strategy 2025-2027 is included in the appendix to this current report.

      A presentation of Mabion S.A.'s Strategy for 2025-2030 and an update of the ESG Strategy for 2025-2027 is available on the Company's website at: https://www.mabion.eu.

      The Company announced the adoption of the 2025-2030 Strategy and the update of the ESG Strategy in current report No. 33/2025 of 17 November 2025.

    9. Factors that will affect the results achieved in at least the next quarter

      The main factors that will affect the Company's results in subsequent quarters are:

      • the implementation of newly acquired contracts for international clients,

      • the possibility of acquiring new customers in the CDMO area in the field of production, development and analytical work,

      • the possibility of expanding cooperation with current clients in the area of continuing analytical work and expanding it to include new items in Mabion's portfolio,

      • accelerating efforts to implement projects currently in the preparatory phase,

      • establishing an Advisory Board,

      • the possibility of meeting financing needs by obtaining the necessary funds (debt financing, attracting an industry or financial investor, issuing the Company's shares or combining selected or all of the above financing options﴿,

      • continuation of the performance of the contract for analytics commissioned by Novavax, as well as the performance of additional orders placed under other contracts,

      • future, possible changes in the terms of the contract with Novavax or IBMP,

      • the decision of the National Centre for Research and Development (NCBR﴿ regarding the acceptance of the implementation report and the report on the dissemination of R&D results of the project entitled "Development and scaling of an innovative process for the production of a therapeutic, recombinant monoclonal antibody to enable the industrial implementation of the first Polish biotechnological drug for oncological and autoimmune therapies",

      • the availability of grants and funds supporting the development of the biotechnology industry, including research and development projects and investments in innovation, may affect the acquisition of new contracts,

      • changes in remuneration costs and general administrative costs of the Company,

      • exchange rate differences resulting from changes in foreign exchange rates,

      • the level of inflation and interest rates affecting the level of costs generated.

        Implementation of the 2025-2030 Strategy in terms of activities planned for 2025 - commercialisation, acceleration of expansion, securing financing

        The Mabion S.A. Strategy for 2025-2030, adopted on 23 April 2025, assumed that 2025 would be crucial for converting existing customer relationships into contracts. Business development activities were intensified and, as a result, a significant increase in the number of contracts signed was planned (the assumptions and activities planned in the strategy were aimed at acquiring 5 to 10 contracts in 2025﴿. The Company's Management Board's goal for 2025 was to increase sales revenue compared to 2024, mainly thanks to the expected translation of established business relationships into contracts.

        As at the date of publication of this interim report, the total value of all offers actively negotiated by the Company with potential

        customers, taking into account the likelihood of successfully signing a contract, reached USD 50.7 million. The Company directs its offer mainly to small and medium-sized biotechnology companies, competing on the market primarily for projects worth PLN 10-40 million, offering flexible terms of cooperation, a fast implementation path and a cost advantage over other CDMOs. The second key target are well-established companies interested in the co-development of biotechnology products.

        However, given the slower than expected progress in securing contracts, the Company's Management Board believes that the assumptions made for 2025 will be difficult to achieve despite all the Company's best efforts. Therefore, considering the current situation of the Company and the changes in the composition of the Company's Management Board that took place in September 2025, the assumptions of the Strategy 2025-2030 adopted in April this year Strategy 2025-2030 were revised and on

        17 November 2025 a new Company Strategy for 2025-2030 was adopted for implementation. Detailed information on the adopted strategy can be found in section 3.8 of this report.

        After analysing the possibilities of obtaining financing (debt financing, equity or mezzanine financing from local or international investors or financial institutions﴿, in the first half of 2025 the Company continues its efforts to develop an optimal financing structure, which would come from the following sources (alternatively or through joint implementation﴿:

        1. obtaining debt financing, mainly from private debt funds,

        2. obtaining financing through the issue of shares,

        3. acquiring an industry or financial investor who would co-finance the Company.

        The scenario currently being implemented is to obtain bridge financing from existing investors, which, in the opinion of the Management Board, is the optimal source of short-term financing until the appropriate level of financing required in the medium term is obtained. The Company's Management Board also continues to actively pursue activities aimed at obtaining debt financing from Private Debt funds and is taking steps to increase the Company's share capital through the issue of shares. In the opinion of the Management Board, these activities may supplement the estimated capital requirements. Acquiring an industry or financial investor who could significantly recapitalise the Company is one of three scenarios that the Company began to implement in April with the announcement of its 2025-2030 Strategy.

        Work is currently underway to increase the Company's share capital at the beginning of 2026 through the issue of shares, which will provide the Company with funds to manage its liquidity in the coming months. It is estimated that as a result of the planned issue, the Company will be able to obtain additional funds up to the amount of the authorised capital (i.e. an issue of up to 8,081,163 shares﴿, which, in the opinion of the Company's Management Board, will secure the Company's liquidity for the coming months. The planned issue will be closed and will not be conducted as a public offering. The Company's Management

        Board believes that the risk of failure to recapitalise through a capital increase in the form of a share issue is negligible, but there is no certainty of this.

        Due to the complexity of the above-mentioned processes and their duration, the Company requested its shareholders to provide bridge financing in the form of a loan. As a result of the actions taken, on 24 October 2025, the Company concluded a Term Sheet with Twiti Investments Ltd. Term Sheet, a loan agreement under which Twiti Investments granted the Company a loan in the amount of PLN 18 million for a period of two years. On 3 November 2025, the Company received the first tranche of the loan in the amount of PLN 6 million.

        In the opinion of the Management Board, obtaining the loan will enable the Company to carry out its current operations and maintain its readiness and ability to perform new contracts. At the same time, the Company sees a need for further external financing, in the form of debt financing or share issues, as indicated above.

        In the event that the actions of the Company's Management Board in terms of obtaining sales contracts or external financing prove insufficient, On 25 September 2025, the Company received a letter of support from its shareholder Twiti Investments, in which the shareholder upheld its decision to provide support as expressed in its letter of 31 March 2025, while also declaring its support for a further 12 months.

        The critical scenario currently being considered following changes in the Company's Management Board (described in section 2.2 of this report﴿ is to reduce operating costs and capital expenditure. Such a scenario would support measures aimed at maintaining liquidity until a sufficient number of production orders are obtained. This scenario is currently being considered, taking into account the implementation of operational and manufacturing processes related to the performance of signed contracts, as well as the acquisition of new contracts. In the opinion of the Company's Management Board, the performance of all signed contracts is a priority over possible measures aimed at radically reducing costs, as such measures would impair the Company's operational capacity and thus undermine its ability to perform important contractual obligations.

        Despite intensive market activities, the Company's Management Board identifies significant uncertainty regarding the possibility of acquiring and executing a sufficient number of production orders that would guarantee the Company cash resources ensuring liquidity in the foreseeable future. In addition, the Company sees a risk of a potential return of part or all of the subsidy received from NCBiR (the total subsidy amounts to PLN

        24.9 million﴿ together with interest due for the implementation of the project related to the MabionCD20 drug, which could significantly affect the Company's financial condition. Detailed information in this regard is described in note 18 and 26 of the financial statements, where the Company referred to liquidity risk. The Company's Management Board believes that the risk of repayment is negligible, but cannot rule it out.

        Therefore, there is significant uncertainty that may raise serious doubts about the Company's ability to continue as a going concern and, as a result, the Company may not obtain the expected economic benefits from its assets and may not settle its liabilities in the normal course of business. In the opinion of the Management Board, however, the market activities currently being undertaken and the status of talks with potential contractors give grounds to assume that the Company will continue its operations and that there is demand for the services it offers.

        Factors related to the situation in Ukraine

        At the time of publication of this interim report, the armed conflict in Ukraine, a country neighbouring Poland, which began in 2022, is still ongoing. The international community has imposed severe sanctions on Russia, which attacked Ukraine, targeting specific entities and sectors of the economy. As at the

        date of publication of this interim report, the sanctions imposed and the armed conflict have not had a direct impact on the Company's operations. Therefore, after analysing the impact of the Russian invasion to date and its current and future potential effects on the Company, the Company's Management Board believes that the invasion and its related effects do not affect the valuation and classification of assets and liabilities in the condensed interim financial statements as at 30 September 2025.

        However, changing exchange rates, interest rates, economic growth potential, the impact of increased immigration and the possibility of the conflict spreading have increased the uncertainty of the environment in which the Company operates. The current economic situation in the East has prompted the Company to pay particular attention to regulations introduced by the Polish Government, the governments of other EU countries and the United States. The protracted conflict may result in further increases in prices, e.g. of energy, the introduction of restrictions on free trade or other business restrictions, including disruptions to the supply chain of goods and services. All of the abovementioned phenomena may have a direct impact on the Company's financial situation in the future.

  2. ‌OTHER INFORMATION RELEVANT TO THE ASSESSMENT

OF THE COMPANY'S SITUATION

As at the date of this interim report, there is no information other than that indicated in the other sections and below that is relevant to the assessment of the Company's personnel, assets, financial position, financial results and changes therein, or information that is relevant to the assessment of Mabion S.A.'s ability to meet its obligations.

The interim condensed financial statements for the 3- and

9-month periods ended 30 September 2025 have been prepared in accordance with the going concern principle, which assumes that the Company will continue as a going concern in the foreseeable future. The assumptions underlying the going concern principle are presented in note 3 to the interim condensed financial statements.
