{2}------------------------------------------------

In the third quarter of 2025, Mendus shaped up its clinical development plans for the lead program vididencel in myeloid malignancies.
The updated clinical strategy positions vididencel more broadly as a post-remission therapy in acute myeloid leukemia (AML) and includes chronic myeloid leukemia (CML) as an additional indication. The ambitious plan is based on our continued positive data with vididencel in AML and follows the recent appointment of Tariq Mughal as Chief Medical Officer. Mendus also announced a corporate reorganization to offset new clinical trial expenses. In its earlier stage pipeline, Mendus reported the granting of a US patent covering the use of vididencel in ovarian cancer following positive clinical data presented at ASCO and a preclinical collaboration in AML with an international biopharmaceutical company.
The Phase 2a ADVANCE II trial studies vididencel as a post-remission monotherapy following high-intensity chemotherapy in high-risk AML, with all patients having measurable residual disease (MRD) at study entry. In the most recent read-out, the majority of patients treated were alive and disease-free at 48 months median follow-up. In the randomized Phase 2b AMLM22-CADENCE trial, vididencel is combined with oral azacitidine, which is currently licensed for maintenance treatment, in adults patients with AML in CR1 following intensive chemotherapy induction, irrespective of their MRD status. The trial, supported by the Australasian Leukaemia and Lymphoma Group (ALLG), broadens the positioning of vididencel beyond MRD-positive patients and significantly expands its target population. Early October, Mendus reported that 12 patients had been enrolled in the CADENCE trial, with the goal to reach 20 in the first quarter of 2026.
As part of its strategy to position vididencel broadly in AML, Mendus has prepared a Phase 1b (DIVA) trial to evaluate vididencel as an adjunct immunotherapy for patients receiving frontline induction therapy with venetoclax and
azacitidine (Ven-Aza), currently considered the standardof-care frontline therapy for AML patients unfit for intensive therapy. However, this combination is far from curative, creating a growing patient population in need of novel treatments to prevent disease relapse without adding toxicity. Following our promising preclinical data of combining vididencel with Ven-Aza presented at ASH 2024, there was considerable enthusiasm from global AML experts to test this strategy in the clinics. Initial topline data from both CADENCE and DIVA trials are expected mid-2026 and will inform the go-to-market strategy for vididencel in AML.
In the third quarter of 2025, Mendus has also entered into a preclinical research collaboration with an international biopharmaceutical company to study vididencel in combination with targeted therapy in AML.
Building on the durable clinical responses and robust safety profile observed in AML, Mendus will initiate clinical development of vididencel in chronic phase CML. While tyrosine kinase inhibitors (TKIs) transformed CML from a fatal disease to a chronic condition, most patients require lifelong therapy, which carries risks of toxicity, serious adverse events, and significant impact on the quality of life; it is also considerably expensive. The notion of a 'treatment-freeremission' (TFR) has therefore been considered important in CML and has been tested with modest success. Based on the convincing demonstration that an immune effect plays a central role in eliminating MRD after an allograft. Furthermore, our preclinical data presented at ASH 2024, supports this concept and the potential for vididencel in CML, first to facilitate TFR safely and second to maintain TFR effectively. Initial Phase 1a/b safety data are expected mid-2026, to support the start of a Phase 2a trial evaluating vididencel in patients who previously failed TFR attempts.
{3}------------------------------------------------

In its earlier-stage pipeline, Mendus was granted a patent covering the use of vididencel in ovarian cancer by the United States Patent and Trademark Office (USPTO). This further validated the potential of vididencel as an active immunotherapy in this indication, following positive clinical data presented at the ASCO 2025 conference from the Phase 1 ALISON trial carried together with the University Medical Center Groningen (UMCG). The next read-out of the ALISON trial based on 2-year follow-up is anticipated in the fourth quarter of 2025. Mendus and UMCG also presented data confirming the use of Mendus' proprietary DCOne platform for the expansion of tumor-infiltrating lymphocytes (TILs) at the SITC 2025 conference. The data showed superior expansion and functionality of TILs in the presence of DCOne-derived dendritic cells, as a basis for TIL-based treatment of ovarian cancer and potentially other solid tumors.
In conjunction with the increased focus on execution of its clinical strategy, Mendus has announced a reduction of
its staff, including the company's executive management team. The cost savings realized by the corporate reorganization are estimated to offset the extra trial costs anticipated for 2026.
With the updated clinical strategy in place, Mendus is in a strong position to capture the vididencel opportunity in myeloid malignancies, with multiple milestones anticipated in 2026. The durable remissions associated with vididencel treatment, combined with an excellent safety profile may allow AML and CML patients to experience longer periods of treatment-free survival. We look forward to keeping our stakeholders updated of our progress towards this ultimate goal.

Mendus in short – Q3 2025
Mendus is developing novel cancer therapies based on active immunity to control residual disease and prolong survival of cancer patients without harming health or quality of life.

Changing the course of cancer treatment
In today's cancer therapy landscape, many cancer patients experience an initial treatment success, leading to clinical remission. However, tumor recurrence remains an imminent threat and causes the vast majority of cancer-related deaths today. As a result, there is an increasing need for therapies that improve disease-free and overall survival following first-line treatment, particularly in tumor indications with a high recurrence rate.
Mendus is developing immunotherapies that result in active immunity, built up by the patient's own immune system, which has the potential to provide long-term immune control over residual cancer cells.
Vididencel in AML
Vididencel is an immunotherapy comprising irradiated leukemic-derived dendritic cells. These cells are manufactured from the company's proprietary DCOne production cell line using a scalable production process that does not require patient material or genetic engineering. The final product is irradiated, stored frozen and shipped to hospitals on demand. Vididencel is administered via injection in the skin, where it triggers local immune activation and phagocytosis by antigen-presenting cells, triggering an immune response against the cancer antigens expressed by the product. Results from multiple clinical trials have consistently demonstrated vididencel's ability to induce durable immune responses, combined with an excellent safety profile. The clinical development of vididencel in AML is supported by Orphan Drug status (EU + US) and Fast-track Designation (US). The manufacturing process has been validated by an ATMP certificate issued by the European Medicines Agency (EMA).
The ongoing ADVANCE II Phase 2 trial evaluates vididencel as a post-remission treatment following intensive chemotherapy for AML patients with measurable residual disease (MRD). Vididencel has continued to demonstrate unprecedented long-term overall survival in the ADVANCE II trial, showing durable remissions and confirming vididencel's
{5}------------------------------------------------
mechanism as an active immunotherapy. With a median follow-up of 48 months, the majority of patients remain alive, with several surpassing five-year survival. Immunomonitoring data confirmed that vididencel treatment stimulated broad immune responses, which were closely associated with the observed clinical benefit.
Vididencel is being evaluated in combination with oral azacitidine (aza) in the randomized Phase 2b AMLM22- CADENCE trial, addressing all risk categories of AML including MRD-positive and -negative patients. The trial is supported by the Australasian Leukaemia & Lymphoma Group (ALLG) and will recruit up to 40 patients in a safety and feasibility stage, followed by an efficacy stage up to 100 patients.
Mendus has prepared the Phase 1b DIVA trial to evaluate vididencel as a post-remission treatment in AML patients unfit for intensive chemotherapy, treated with a combination of azacitidine and venetoclax (aza+ven). The trial will be led by Prof Andrew Wei, who is also a lead investigator of the CADENCE trial.
Mendus has also initiated a preclinical research collaboration with an international biopharmaceutical company to study vididencel in combination with targeted therapy in AML.
The late-stage clinical development strategy in AML aims to address the full spectrum of post-remission therapy. Vididencel has been shown to act across AML subtypes and independently of specific genetic mutations. Supported by a favorable safety profile and robust preclinical data, vididencel can be combined with current and emerging AML backbone therapies, enabling Mendus to broaden the addressable patient population and define the optimal path towards market entry. Initial topline data from the CADENCE and DIVA trials expected mid-2026 will guide the go-tomarket strategy for vididencel in AML.
To support late-stage clinical development and commercial-scale manufacturing, Mendus has established a strategic manufacturing alliance with NorthX Biologics. Mendus and NorthX Biologics have co-established a vididencel manufacturing facility and expect to deliver the first large-scale production of GMP material in the second half of 2025.
Indication expansion – CML
Building on positive AML data and supported by a strong safety profile, Mendus is expanding vididencel development into chronic myeloid leukemia (CML). The goal is to improve immune-mediated control of residual disease and support durable treatment-free remission (TFR) in patients treated with tyrosine kinase inhibitors (TKIs). While TKIs have transformed CML into a manageable chronic condition, most patients require life-long therapy, which carries risks

of toxicity, serious adverse events, and expensive treatment. Given evidence suggesting immune mechanisms contribute to controlling residual disease post-TKI, and based on preclinical data presented at ASH 2024, Mendus is initiating a clinical strategy to evaluate vididencel in CML.
A Phase 1a/1b trial, led by Prof Bjørn-Tore Gjertsen (University of Bergen, Norway), will assess safety and feasibility, with first data expected mid-2026. If successful, a Phase 2a trial led by Prof Timothy Hughes (University of Adelaide, Australia) will evaluate vididencel's role in improving TFR rates in patients who previously failed TFR attempts.
Ovarian cancer program
In collaboration with the University Medical Center Groningen (UMCG), Mendus is exploring safety and feasibility of vididencel as an active immunotherapy in highgrade serous ovarian cancer. Data presented at ASCO 2025 demonstrated successful stimulation of tumor-directed immune responses following vididencel treatment. At a median follow-up of 19 months, 7 patients had stable disease, which was associated with vididencel-induced immune responses. Long-term follow-up to assess potential survival benefit of vididencel treatment is ongoing and a next read-out of the ALISON trial based on 2-year follow-up is anticipated in the fourth quarter of 2025.
{6}------------------------------------------------
llixadencel – an intratumoral immune primer for hard-to-treat solid tumors
Ilixadencel consists of dendritic cells derived from healthy donor material, which are administered as an intratumoral injection to stimulate local inflammation and cross-presentation of tumor antigens, resulting in a tumor-specific immune response. Ilixadencel has been studied in clinical trials across a range of hard-to-treat solid tumor indications in combination with existing cancer therapies, including tyrosine kinase inhibitors and the immune checkpoint inhibitor pembrolizumab. Further clinical development of ilixadencel will be dependent on partnering.
Preclinical pipeline
As part of the collaboration with UMCG, Mendus has developed improved methods for the expansion of tumor-infiltrating lymphocytes to treat ovarian cancer and potentially other solid tumors using its proprietary DCOne platform. The platform can also be used to expand so-called memory NK cells, which are associated with improved survival in blood cancers. Further development of these applications will be subject to partnering.

Q&A with Prof Bjørn-Tore Gjertsen
Professor Bjørn Tore Gjertsen, MD PhD, has studied Mendus' lead product vididencel in acute myeloid leukemia as part of the ADVANCE II trial. He will also be the principal investigator for the first trial with vididencel in chronic myeloid leukemia.
Professor Gjertsen, can you describe your research background?
BTG: As a Professor of Hematology at the University of Bergen and Senior Consultant Hematologist at Haukeland University Hospital in Bergen, Norway, my general interest is to combine the treatment of myeloid malignancies with research studying the molecular pathways causing the disease. In the Phase I clinical trials unit at Haukeland University Hospital, we focus on clinical trials in CML and AML, combined with biomarker programs, disease profiling and response evaluation. This approach allows us to investigate potential new treatments and obtain a deeper understanding of their potential efficacy at an early stage of development. Collaboration is an essential part of innovation, and we have established multiple organizations to facilitate the exchange of information and expertise, such as the Centre for Cancer Biomarkers (CCBIO). I am currently Director at K.G. Jebsen Centre of Myeloid Blood Cancer, which focuses on gathering basic, translational, and clinical researchers to develop novel concepts for future clinical trials. I am also a founding member and chair of the Norwegian AML Group and the Nordic AML Group, and member of the Nordic CML Study Group. International collaborations are important, illustrated by our collaboration with the Dutch HOVON group in late phase trials in AML. We enrolled our first patients in a HOVON trial in 2009, and we are now as the Nordic AML Group participating in an outstanding trial program through the academic-industry partnership of HOVON.
What do you see as major developments in the treatment of AML?
BTG: AML is a very aggressive disease, which upon diagnosis is treated with chemotherapy to suppress the tumor cells to the level of complete remission. Unfortunately, the morphological assessment of the bone marrow does

not mean the disease is gone. Residual cancer cells put patients at a very high risk of disease relapse, which is often fatal. The only curative method available to treat residual disease is to consolidate the therapy with an allogeneic hematopoietic stem cell transplantation (HSCT). Relapses are seen in a quarter of the transplanted AML patients, again resulting in a very difficult disease to cure. Also, HSCT is a procedure associated with severe side effect, including transplant-related mortality and chronic graftversus-host disease, a serious condition in which the new immune system attacks the tissues of the patient it sees as "foreign". Two main developments have changed the treatment landscape of AML in recent years. First, we are learning to better manage the risks associated with HSCT, mak
{8}------------------------------------------------
ing the procedure more accessible for patients. Secondly, we are increasingly finding molecules that target specific mutations associated with AML and they are allowing us to define more optimal first-line treatments. Particularly, this is the case for venetoclax, a highly effective drug which in combination with another drug, azacitidine, is now used increasingly as an alternative for high-intensity chemotherapy in the first-line treatment of AML. However, we do not know if these targeted therapies can cure patients without HSCT as consolidation.
What has been your experience with vididencel in AML?
BTG: Our center participated in the ADVANCE II trial, in which we treated AML patients who were in a complete remission following chemotherapy but diagnosed with measurable residual disease (MRD), which is associated with a high risk of disease relapse. Vididencel was administered as six intradermal injections, which is a relatively straight-forward route of administration for blood cancer patients who are used to regular monitoring of their blood and bone marrow samples. Interestingly, we saw signs of potential efficacy already early in the trial because several patients experienced a strong reduction of their MRD levels following vididencel treatment. It became even more interesting when we realized that the patients who responded to the therapy early, based on disease monitoring and immunological analyses, had a good chance of long-term disease-free survival. This prospect makes vididencel an interesting product to examine more broadly as a novel post-remission treatment in AML.
How does CML fit into this picture?
BTG: Unlike AML, CML can be effectively suppressed over a long period of time by currently available medication with tyrosine kinase inhibitors (TKIs). Because these treatments are effective and overall survival of CML patients is very close to that of the general population, the attention has shifted from acute disease control to quality of
life. The main struggle for CML patients is the burden of life-long medication and the side effects associated with TKIs. Unfortunately, when treatment is stopped many patients face rising disease levels and have to go back to their earlier or novel TKI treatment. The low success rate of treatment-free remissions, with overall only in one of five patients successfully stopping TKI, may improve if the immune system is able to control residual disease. Therefore, immunotherapy has always been a field of interest in CML. Current available immunotherapies include interferon-alpha and HSCT. However, the clinical benefit of combining TKI with interferon-alpha is unfortunately still unclear and HSCT is an intensive therapy that is a last resort in patients with overt TKI resistance and the aggressive blast crisis. Vididencel could provide an alternative, based on the durable clinical remissions observed in AML combined with a strong safety profile. We first plan to study the effect of vididencel in patients with stable persistent disease levels, establishing safety and initial signs of efficacy. As a next step, we will more broadly explore the use of vididencel to allow more patients to stop TKI treatment safely and successfully.
What is the ultimate goal in treating myeloid blood cancers?
BTG: Ultimately, we strive to effectively control disease to a point where patients can be considered cured, without the need for further treatment. So far, this has been very difficult in myeloid blood cancers. We are putting a lot of effort into better understanding how we can better predict the response to available treatments, to adjust treatments quickly and effectively to result in better outcomes for patients. It will be most rewarding if therapies become so successful that patients can experience long periods free of treatment, in which they can live healthy lives without the imminent risk of recurrence of their disease. Although a lot more research is needed, immunotherapy has the potential to deliver that prospect.

Review report
To the Board of Directors of Mendus AB (publ) Corp. id. 556629-1786
Introduction
We have reviewed the condensed interim financial information (interim report) of Mendus AB (publ) as of 30 September 2025 and the nine-month period then ended. The Board of Directors and the Managing Director are responsible for the preparation and presentation of this interim report in accordance with IAS 34 and the Annual Accounts Act. Our responsibility is to express a conclusion on this interim report based on our review.
Scope of review
We conducted our review in accordance with International Standard on Review Engagements ISRE 2410 Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and other generally accepted auditing practices and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
Conclusion
Based on our review, nothing has come to our attention that causes us to believe that the interim report is not prepared, in all material respects, for the Group in accordance with IAS 34 and the Annual Accounts Act, and for the Parent Company in accordance with the Annual Accounts Act.
Material uncertainty related to going concern
We draw attention to the information in the interim report note 4 (page 24) which states there is a risk the available liquidity as of September 30 2025, will not fund operations after the beginning of 2026 and the company will need to access additional capital to be able to continue to advance the development of the various programs. It also states that the Board is monitoring the situation and is evaluating different financing options and if the financing is insufficient, this indicates a risk about the Group's ability to continue its operations. These circumstances indicate that there are material uncertainties that may cast significant doubt on the Group's ability to continue as a going concern. Our conclusion is not modified in respect of this matter.

Notes
Note 1 – General information
Mendus AB (publ) (hereinafter "Mendus"), 556629-1786 is a Swedish public limited company with its registered office in Stockholm. The address of the Company's head office is Västra Trädgårdsgatan 15, SE-111 53 Stockholm, Sweden. On November 12, 2025, the Board of Directors approved this interim report for publication.
Note 2 – Accounting principles
The consolidated financial statements of Mendus have been prepared in accordance with the applicable parts of the Swedish Annual Accounts Act, RFR 1 Supplementary Accounting Rules for Groups, as well as International Financial Reporting Standards (IFRS®) and interpretations from the IFRS Interpretations Committee (IFRIC®) as adopted by the EU. The consolidated financial statements have been prepared in accordance with the acquisition method.
The interim report has been prepared in accordance with IAS 34 Interim Financial Reporting and the Annual Accounts Act.
The Parent Company's interim report has been prepared in accordance with the Annual Accounts Act and the Swedish Financial Reporting Board's recommendation RFR 2.
The Group's accounting principles are unchanged and are presented in the Annual Report for 2024 (Note 2, pages 36-38).
In cases where the Parent Company applies accounting principles other than the Group's accounting policies, these are presented in the Annual Report 2024 (Note 2, page 50).
Note 3 – Important estimates and judgments for accounting purposes
The preparation of financial statements requires the use of accounting estimates, which will rarely correspond to actual earnings. Management also makes judgments in the application of the Group's accounting principles. These assessments are unchanged and are presented in the Annual Report for 2024 (Note 5, page 39).
Note 4 – Prospects, significant risks and uncertainty factors
Mendus is a research and development company. The company has not generated any significant revenue historically and is not expected to do so in the near term. The Company's product candidates are dependent on research and development and may be delayed and/or incur higher costs. The Company is dependent on its ability to enter into license agreements and joint cooperation agreements, as well as on a large number of approval and compensation systems and related laws, regulations, decisions and practices (which are subject to change). In addition, the Company is dependent on intellectual property rights. The risk that is considered to be of particular importance for Mendus' future development is access to sufficient financial resources to support the Company's financing needs. The company's Board of Directors and management continuously monitor and evaluate the Group's financial status and the availability of cash and cash equivalents.
There is a risk that the available liquidity as of September 30, 2025, will not fund operations after the beginning of 2026 and the company will need to access additional capital to be able to continue to advance the development of the various programs.
The Board is monitoring the situation and is evaluating different financing options including timing and scope for raising capital that can be beneficial to the company. The Board believes that the prospects for raising capital are good. However, if financing is insufficient, this indicates material uncertainty, which could lead to significant doubts about the Group's ability to continue its operations.
This report contains forward-looking statements. Actual results may differ from what has been stated. Internal factors such as successful management of research projects and intellectual property rights can affect future performance. There are also external conditions, such as the economic climate, political changes, and competing research projects that can affect Mendus' results.

Key performance measurements
The company presents in this report certain key performance measures, including two measures that is not defined under IFRS, namely expenses relating to research and development/operating expenses and equity ratio. These financial performance measures should not be viewed in isolation or be considered to replace the performance indicators that have been prepared in accordance with IFRS. In addition, such performance measure as the company has defined it should not be compared with other performance measures with similar names used by other companies. This is because the above-mentioned performance measure is not always defined in the same manner, and other companies may calculate them differently to Mendus.
