When I took the helm of Oncopeptides just before our latest quarterly report, I set out to continue the work I had done as CCO, building out our commercial organization in Europe, ensuring we make a difference to patients and grow sales. Additionally, me and the leadership team have recently taken some important strategic decisions to ensure value creation for the company beyond the commercialization of Pepaxtiin Europe, which still remains our main focus. I am pleased to see that we have tripled the number of sold vials in Germany quarter over quarter, despite the vacation period in the third quarter. The positive trend continues into the fourth quarter as the number of sold vials in October alone almost reached the number of the entire third quarter. A key milestone during the second quarter was the finalization of the successful price negotiation in Germany, resulting in a reimbursed list price of €7,058 per monthly dose, which is in line with our financial expectations, and a price we believe to be fair and reflect the innovation of Pepaxti, especially considering the rapidly changing multiple myeloma treatment landscape. This is a critical milestone that we are proud to have reached as the price in Germany will be referenced in other price negotiations across Europe. We have also continued to progress in our launch preparations, and I am happy to share that we in addition to the Netherlands have submitted value dossiers in Spain and Italy which is moving us into the next phase of market access in those countries and one step closer to launches. Furthermore, we have submitted a dossier to explore if we can launch in Ireland through a simplified market access path. At the same time, we continue to be strategic in our investments and remain cost conscious overall. R&D costs were unusually low in the quarter as an effect of one-time items with refunds from completed studies amounting to approximately 13.6 million SEK. Our financial discipline with good cost control gives us confidence in maintaining liquidity until the end of the second quarter 2024. Another important event during the third quarter was the positive opinion granted by the Committee for Medicinal Products for Human Use (CHMP), part of the European Medicines Agency (EMA) on our application for earlier lines of treatment. The positive opinion yet again confirms the clinical benefit /risk profile of Pepaxtiand verifies the results of our phase 3 study OCEAN. Based on a thorough assessment of the rapidly evolving treatment and payer landscape we later opted to abandon the application process. This is due to a higher estimated patient and shareholder value in later lines of treatment, a decision that has no negative effect on the estimated market potential for Pepaxtiin Europe or our revenue projections. We have also continued our dialogue with relevant authorities in the USA regarding our appeal of the U.S. Food and Drug Administration´s decision to recommend withdrawing Pepaxtofrom the market. At this stage we cannot predict the outcome, but regardless I am immensely proud of the Oncopeptides’ team for expressing our confidence in Pepaxtoand presenting the science behind it in such a professional and factual way. In addition to our ongoing European launch, we as a company, have spent some time ensuring that there is a path forward for Oncopeptides beyond our European Pepaxtisales. We have started to explore market potential and initiated early-stage discussions with potential business development partners outside of Europe. We have also continued to advance research to further develop and commercialize our pipeline of drug candidates leveraging our two innovation platforms focused on difficult-to-treat cancers, PDC and SPIKE, and we look forward to our first candidate drug selection for the SPIKE platform to take place early next year. I call our potential sales of Pepaxtiin the rest of the world and development of our pipeline our “next step value drivers”, and I will regularly come back with more information as we progress further. For now, it´s important for me to communicate that, thanks to the people that work here and the science we have, I see a potential in this company well beyond where we stand today. Looking into the last quarter, we expect to end the year with a maintained upward trajectory for our sales and take additional steps to expand our commercial footprint across Europe, while also seeing the FDA appeal process through and further explore additional growth opportunities from our next step value drivers. Lastly, I would like to thank the Oncopeptides team for their hard work and valuable contribution to our company, and our shareholders for your continued support and trust.

The loan agreement is divided into three tranches, each with a maturity of five years, and made available if the company reaches certain milestones. If the company exercises the full loan facility, the EIB will be entitled to warrants equivalent to 2.8% of outstanding shares in Oncopeptides, in addition to interest on the loan amount.

In connection to the payment of the loan, warrants representing 1.26% of outstanding shares after dilution has been transferred to EIB without compensation.

Group equity amounted to SEK 133.4M (380.3) at the end of the period. Equity is in its entirety attributable to the Parent Company´s shareholders. THE WAR IN UKRAINE The situation in the Ukraine is not deemed to have any material effects on the operations of the company. GOING CONCERN This interim report is issued based on the assumption of going concern for at least twelve months. The current cash balance is not estimated to cover twelve months but is estimated to be sufficient for the continued operation of the business at least until the end of the second quarter 2024. The basis for the assumption of going concern is that the company has the option to postpone activities and investments and achieve additional financing in order toprolong the sustainability of the current liquidity. Should decisive conditions not be met, for example by sales not developing as expected, the Group's continued operation might be at risk. This means that there are circumstances that may give rise to significant doubts about the company's ability to continue operations without additional financing of the parent company within the next twelve months. It is the assessment of the Board of Directors and the CEO that there are many alternatives with good prospects to obtain additional financing within the next twelve months. The alter- natives include licensed revenues through partnerships in specific markets and raised capital from current shareholders´ and other external investors. EMPLOYEES The number of FTE:s for the period was 64.2 (49.5). PARENT COMPANY Parent company operations are aligned with those of the Group, why the comments for the Group are also relevant for the Parent Company. ONCOPEPTIDES SHARE At the end of the period, the number of registered shares eligible for trading and votes in Oncopeptides amounted to 90,439,627. 3ONCOPEPTIDES INTERIM REPORT JANUARY - SEPTEMBER 2023 ===== SIDA 4 ===== Signatures 4 The Board and the CEO confirm that the interim report provides a true and fair reflection of the Group’s and the Parent Company’s operations, position and earnings and describes the material risks and uncertainty factors faced by the Parent Company and the companies within the Group. Stockholm, November 7, 2023 Per Wold-Olsen Chairman Jennifer Jackson Board member Cecilia Daun-Wennborg Board member Per Samuelsson Board member Jarl Ulf Jungnelius Board member Brian Stuglik Board member Sofia Heigis CEO ONCOPEPTIDES INTERIM REPORT JANUARY - SEPTEMBER 2023 ===== SIDA 5 ===== Review report 5ONCOPEPTIDES INTERIM REPORT JANUARY - SEPTEMBER 2023 This is a translation from the Swedish original Oncopeptides AB (publ) corp. reg. no. 556596-6438. INTRODUCTION We have reviewed the condensed interim report for Oncopeptides AB as at September 30, 2023 and for the nine months 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 Swedish Annual Accounts Act. Our responsibility is to express a conclusion on this interim report based on our review. SCOPE OF VIEW We conducted our review in accordance with the International Standard on Review Engagements, ISRE 2410 Review of Interim Financial Statements Performed by the Independent Auditor of the Entity. A review 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 standards in Sweden. The procedures performed in a review do 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, in accordance with IAS 34 and the Swedish Annual Accounts Act regarding the Group, and in accordance with the Swedish Annual Accounts Act regarding the Parent Company. MATERIAL UNCERTAINTY RELATED TO GOING CONCERN We draw attention to the section Going concern page 3 in the interim report, which indicates that existing liquidity is not expected to cover the next 12-month period without additional financing. Should crucial conditions not be met, such as sales not developing as expected and additional financing not being obtained, there is a risk concerning the company's ability to continue as a going concern. These events or conditions, along with the other matters mentioned, indicate that a material uncertainty exists that may cast significant doubt on the Company’s ability to continue as a going concern. Our opinion is not modified in respect of this matter.

The company assesses that the risks that are described in the 2022 annual report still remainexcept the risk related to going concern which is presented on page 3 in the interim report. NOTE 4 - ESTIMATES AND CONSIDERATIONS This report includes forward looking statements. Actual outcomes may vary from what has been stated. In addition, internal factors such as successful management of research projects, and intellectual property rights may affect future financial outcomes. This interim report is issued based on the assumption of going concern for at least twelve months. The current cash balance is not estimated to cover twelve months but is estimated to be sufficient for the continued operation of the business at least until the end of the second quarter 2024. The basis for the assumption of going concern is that the company has the option to postpone activities and investments and achieve additional financing in order to prolong the sustainability of the current liquidity. Should decisive conditions not be met, for example by sales not developing as expected, the Group's continued operation might be at risk. This means that there are circumstances that may give rise to significant doubts about the company's ability to continue operations without additional financing of the parent company within the next twelve months. It is the assessment of the Board of Directors and the CEO that there are many alternatives with good prospects to obtain additional financing within the next twelve months. The alternatives include licensed revenues through partnerships in specific markets and raised capital from current shareholders´ and other external investors. NOTE 5 - REVENUE RECOGNITION The principles used for revenue recognition are the same as described in the 2022 Annual Report. Revenue is recognized at the transaction price for goods sold, excluding VAT, discounts and returns. Revenue is recognized at the time of delivery, when Oncopeptides has fulfilled its performance commitment, and the control of the products are trans- ferred to the customer. Customers are defined as hospitals and/or clinics and resellers who sell the products, at an intermediate stage, to the final user of the products. Since the final price is related to the discount which is valid on each local market and which is paid to the patients’ insurance companies, the transaction price is not known upon delivery. This is regulated by booking a provision for the estimated discount in the parent company and Group, based on the framework for discounts which is valid on each market. The provision for estimated discounts is reported under the headline Other current liabilities in the balance sheet. The provision for expected returns, related to the withdrawal of Pepaxto from the US market in 2021, has been fully dissolved at the end of the period, since the period open for returns according to agreement came to an end during July 2023. The estimation is that there are no significant risks for returns related to the goods sold in Europe during the period. NOTE 6 – LOANS FROM CREDIT INSTITUTIONS The liability relate to a loan from EIB. It will not be amortized until the 16 th of June 2028, when it will be fully repaid. The interest is accumulated and capitalized during the term and paid in connection to the repayment of the loan. The contractual interest rate is 7% for the full term. The effective interest rate is estimated to 10.8%, including arrangement costs and the initial market value of the transferred warrants allocated during the term of the loan. In connection to the signing of the agreement, an emission of 2 829 231 warrants was performed, whereof 1 138 646 warrants representing 1.26% of outstanding shares after dilution has been transferred to EIB without compensation. The remaining warrants are held by the company and may be transferred to EIB in connection to a possible utilization of the remaining tranches related to the loan agreement. EIB has the right to exercise the warrants and subscribe for shares at the quota value. The warrants may be exercised at any time for a period of 20 years, in full or in part, by the warrant holder. EIB has the right, under certain circumstances and in connection to the repayment of the loan, to demand that Oncopeptides acquire the warrants in a situation when it is not possible to transfer the warrants to a third party.
