A quarter marked by the successful completion of the business combination, steady progress advancing our lead TCR-NK asset, and the major milestone of securing manufacturing to enable clinical readiness.
The successful completion of the business combination between Ultimovacs and Zelluna Immunotherapy marked a significant milestone this quarter. With this, we have strengthened Zelluna both structurally and strategically, creating a publicly listed company with a singular focus: to advance our pioneering TCR-NK cell therapy platform.

This quarter has been shaped by three core activities — completing the combination, progressing the integration, and driving forward our lead TCR-NK asset toward clinical readiness. We secured a key milestone in locking down our manufacturing process further derisking our path to the clinic and laying the groundwork for first-in-human trials.
Zelluna's TCR-NK platform represents a truly novel and highly differentiated approach to cell therapy — designed to overcome the limitations of current treatments, especially in solid cancers. We believe this positions us to deliver both patient impact and long-term value for shareholders.
Recent high-profile transactions in the cell therapy field highlight the strong appetite for breakthrough technologies – including deals involving early-stage companies with compelling data from very few patients, such as AstraZeneca's acquisition of Esobiotec. These moves underscore the significant opportunity ahead. Zelluna is well-positioned to capture value as we advance our highly differentiated TCR-NK platform towards clinical entry.
Looking ahead, our focus remains clear: executing on the clinical path, building momentum, and continuing to attract interest from investors and partners who share our vision. I'm proud of the disciplined progress made in Q1 and confident in our trajectory for the year ahead.
— Namir Hassan, CEO

Cell therapies have demonstrated curative potential in late-stage cancer patients with nine products approved to date. Several of these approvals were achieved with data from fewer than 100 patients, underscoring the speed and impact possible in this field. However, two major challenges remain: 1) delivering similarly transformative outcomes in solid tumours – as most approved therapies target blood cancers – and 2) scaling manufacturing to meet broader demand, since all current approved therapies require a batch of treatment manufactured for each individual patient.
Zelluna is developing a novel allogeneic cell therapy platform combining Natural Killer ("NK") cells with tumour specific T cell receptors ("TCRs") ("TCR-NK") to address the key challenges of cell therapy. The TCR-NK products are composed of healthy donor derived NK cells that are genetically engineered to express a tumour specific TCR that enable the TCR-NK cells to identify and eliminate cancer cells in the body of the patient. Zelluna's core TCR-NK technology leverages both the innate anti-cancer activity of NK cells and the precise tumour targeting capability of TCRs to overcome tumour heterogeneity – which is limiting current cell therapies – and to provide long lasting clinical responses in patients with advanced solid cancer. Furthermore, TCR-NK doses can be manufactured upfront to serve patients on demand at a large scale – where scaling is a limitation for current therapies – and the general safety profile of NK cells may enable dosing of patients in an outpatient setting facilitating broader applicability. Zelluna`s lead, ZI-MA4-1, is in late preclinical and is the world's first MAGE-A4 targeting TCR-NK therapy advancing into phase I/II trials to evaluate the safety and efficacy of the treatment for various advanced solid tumours. Clinical data from our lead TCR-NK asset will inform on the therapeutic potential of our entire platform.

Zelluna pipeline
On 22 April 2025, Zelluna reported that it has successfully developed, scaled and automated its proprietary manufacturing process for its TCR-NK cell therapies. This milestone represents a major advancement in the Company's preparation for clinical entry to provide life-changing, innovative treatments for patients battling cancer. The proprietary manufacturing process is applicable to any product emerging from the Company's pipeline which means any TCR-NK

product can be plugged into the established manufacturing process strengthening Zelluna's dominance of the TCR-NK therapeutic field.
Establishing and locking down a manufacturing process marks an essential step towards the production of TCR-NK cell therapies for clinical development and future commercialization. Based on the established manufacturing process, hundreds of doses could be produced from a single manufacturing batch highlighting scalability and low cost of goods potential. Zelluna continues to advance its lead TCR-NK cell therapy candidate ZI-MA4-1 in preparation for a filing in the second half of 2025 to begin clinical development targeting a variety of solid tumours.
Zelluna has partnered with Catalent, a leading global contract development and manufacturing organization (CDMO), for process development and manufacturing. Catalent brings significant experience in cell therapy manufacturing in compliance with the highest quality standards.
Zelluna holds a foundational concept patent that covers the TCR-NK therapeutic field, and this patent has been granted across key commercial territories such as the USA and Europe. Zelluna has recently also filed patents on products and the proprietary manufacturing process, further building the patent estate.
Zelluna (previously Ultimovacs) has developed a novel conjugation technology. The MultiClick platform consists of a flexible core molecule that can be selectively coupled to several modules. Each module can consist of a defined multiple of targeting units (i.e. molecules that guide the conjugate to a specific tissue or cell type) and active entities (i.e. molecules that exert a desired effect within the tissue, such as cancer cell killing or immune cell activation).
The MultiClick core holds certain potential benefits within CMC (chemistry, manufacturing and controls), including high selectivity, precision, yield, and a scalable and inexpensive manufacturing process compared to biological counterparts (e.g. antibody-drug-conjugates). Zelluna is currently exploring the merits of MultiClick and its potential value.
The therapeutic cancer vaccine UV1 has been evaluated in five Phase II randomized controlled trials in various cancer types in combination with different checkpoint inhibitors, strategically selected for broad evaluation of UV1's potential. Three of the Phase II trials, in malignant melanoma, mesothelioma and head and neck cancer, are completed with disappointing results and therefore the program will be wrapped up. The remaining two trials, LUNGVAC and DOVACC, have completed enrolment and topline results are expected during 2025.

On 9 January 2025, Zelluna ASA held its extraordinary general meeting to primarily approve the business combination, and all formal matters concerning the combination with Zelluna. All matters on the agenda were approved.
Anders Tuv (Chair), Bent Jakobsen, Eva-Lotta Allan, Hans Ivar Robinson and Charlotte Berg-Svendsen were elected as new board members replacing all previous board members with effect from 3 March 2025.
On 29 April 2025, Zelluna ASA held its annual general meeting. There was no election of board members in this annual general meeting.
Full agenda and minutes from the general meetings can be found in the Governance section on Zelluna's website (www.zelluna.com/investors/governance ).
As per the date of this Q1-2025 report, the Management team comprises the following:


Following the successful completion of the business combination, Zelluna enters the next quarter as a strengthened and focused cell therapy company. The integration process is well underway, and the combined organization is now aligned around a shared mission — to bring Zelluna's lead program, ZI-MA4-1 and unique TCR-NK platform into the clinic and demonstrate the platform's potential to treat solid cancers. The primary focus for the remainder of the year will be advancing Zelluna's lead TCR-NK asset toward first-in-human trials with a clinical trial application (IND/CTA) expected to be submitted in 2H 2025. With Zelluna's manufacturing process now locked, the Company is well positioned to continue executing key activities required for clinical readiness. At the same time, and especially given the relevant recent deal activity in the field, the Company remains committed to driving broader awareness of Zelluna's differentiated platform, engaging with potential partners, and delivering on a clear development plan designed to unlock significant value. The solid foundation established in Q1 sets Zelluna up for a year of focused execution and continued momentum.
Looking ahead, and through the treatment of initial patients in a clinical study, we aim to generate key clinical insights that will not only inform the potential of our lead program, ZI-MA4-1 but also validate the broader TCR-NK platform. These data will be central in shaping the direction of our pipeline and future development priorities.
In relation to the business combination, a fully committed private placement providing gross proceeds of appr. MNOK 51.7 was completed to ensure that the Company is sufficiently capitalised to reach a clinical trial application submission (e.g. IND) for its lead asset ZI-MA4- 1, explore the potential of the MultiClick platform, general corporate purposes and extend the Company's expected cash runway through Q2 2026.

Zelluna is exposed to similar generic risks as other companies within this sector. Zelluna has not generated any revenues historically and is not expected to do so in the short term. Zelluna's development, results of operations and operational progress have been, and will continue to be, affected by a range of factors, many of which are beyond Zelluna's control.
Development of pharmaceutical products is subject to considerable risk and is a capitalintensive process. Zelluna is highly dependent on research and development and the programs may be delayed and/or incur higher costs than currently expected.
Zelluna is in an early stage of development and its preclinical and/or clinical studies may not prove to be successful. Zelluna may not be able to obtain regulatory approval to initiate any clinical trials and Zelluna's product candidates may not meet the anticipated efficacy requirements or safety standards, resulting in significant delays, increased costs and/or discontinuation of the development.
Manufacturing of cell therapies is highly complex and Zelluna relies, and will continue to rely, upon third parties for process development and manufacturing of its cell therapy products, and supply of essential materials. There is a risk that TCR-NK products cannot be manufactured at the desired scale, with the required critical quality attributes, potency, viability, purity, cost and other parameters that are deemed required for a TCR-NK product, or at all, which could significantly impact timelines and cost.
Operations may be impacted negatively by changes or decisions regarding laws and regulations. Several regulatory factors have influenced and will likely continue to influence Zelluna's results of operations. Zelluna operates in a heavily regulated market and regulatory changes may affect Zelluna's ability to initiate and perform clinical studies, include patients in clinical trials, protect intellectual property rights and obtain patents, obtain marketing authorization(s), market and sell potential products, operate within certain geographical areas/markets, produce the relevant products, in-license and out-license products and technology, etc.
Competitive cancer treatments and new/alternative therapies, either within immune oncology or within the broader space of oncology, may affect Zelluna's ability to commence and complete clinical trials, as well as the opportunity to apply for marketing authorization, and may influence future sales if marketing authorization is obtained. Competing pharmaceuticals can capture market shares or reach the market faster than Zelluna. If competing projects have a better product profile (e.g. better efficacy and/or less side effects), the future value of Zelluna's product offerings may be lower than expected. The amount and

magnitude of clinical trials within different oncology areas in which Zelluna operates may influence the access to patients for clinical trials.
The primary financial risks are financing risk and foreign exchange risks.
Adequate sources of funding may not be available when needed or may not be available on favourable terms. Zelluna's ability to obtain such additional capital or financing will depend in part upon prevailing market conditions as well as conditions of its business and its operating results, and those factors may affect its efforts to arrange additional financing on satisfactory terms. Zelluna monitors the liquidity risk through monthly rolling consolidated forecasts for result and cash flow, and the Board of Directors works continuously to secure the business operation's need for financing.
Zelluna is conducting a large share of its R&D activities, as well as production, outside of Norway and is therefore exposed to fluctuations in the exchange rate between NOK and several currencies, mainly EUR and USD.
In addition, the Company has an investment in foreign operations, whose net assets are exposed to currency translation risk.
Operational currency exposure is constantly monitored and assessed.
The Group has no interest-bearing debt. Bank deposits are exposed to market fluctuations in interest rates, which impact the financial income.
Zelluna's financial risk exposures are described in more detail in note 17 in Zelluna's 2024 Annual Report.

These interim financial statements are presented in accordance with a reverse acquisition under IFRS 3 Business Combinations, where Zelluna Immunotherapy AS is identified as the accounting acquirer and Zelluna ASA as the accounting acquiree and listed parent company.
As a result of the reverse acquisition, the financial information presented for periods prior to the transaction reflects the operations, financial position, and cash flows of Zelluna Immunotherapy AS only. The historical operations of Zelluna ASA prior to the acquisition are not included in the financial information for periods before 1 March 2025. Please refer to Note 2 for the Basis for preparations and accounting principles for this interim financial report.
Zelluna does not yet generate revenues, as the Company is in a research and development phase.
Total payroll and payroll related expenses were lower in Q1 2025 (MNOK 6.4) compared to the Q1 2024 (MNOK 10.5) due to a reversal of share option expenses, a result of the termination of options for employees having left Zelluna ASA. Regular salaries and related items were, however, higher in Q1 2025 compared to Q1 2024, due to more personnel employed in the Group, a result of the business combination between Zelluna ASA and Zelluna Immunotherapy AS.
Other operating expenses (MNOK 22.2 in Q1 2025 vs. MNOK 24.5 in Q1 2024) are primarily comprised of R&D related expenses. These expenses, including IP and external R&D expenses, offset by government grants, amounted to MNOK 13.0 in Q1 2025 vs. MNOK 18.8 in Q1 2024. The main contributor to R&D expenses in Q1 2025 was chemistry, manufacturing and controls (CMC) activities.
Net financial items amounted to MNOK 1.0 in Q1 2025, compared to MNOK 3.1 in Q1 2024. Financial items are primarily comprised of currency fluctuations from EUR at bank in addition to interest gain from cash at bank accounts.
Total loss for the Q1 2025 period amounted to MNOK 28.3, compared to MNOK 32.8 in Q1 2024.
Total assets per 31 March 2025 were MNOK 169.5, an increase of MNOK 119.0 from 31 December 2024, primarily as a consequence of cash acquired from the business combination and the share issue closed on 3 March 2025.

Total liabilities as of 31 March 2025 amounted to MNOK 42.5, of which none are non-current.
Total equity equalled MNOK 127.0 as of 31 March 2025. Total equity has, since year-end 2024, been increased by MNOK 90.9 due to the business combination and the share issue.
The total net increase in cash and cash equivalents in Q1 2025, excluding currency effects, was MNOK 108.0. Of this, MNOK 51.7 came from the private placement and MNOK 92.4 was acquired through the business combination with Zelluna ASA, offset primarily by negative cash flow from operations of MNOK 36.0.
As part of the business combination, Zelluna ASA acquired 100% of the shares in Zelluna Immunotherapy AS, and Zelluna ASA issued 147,991,521 shares (the "Consideration Shares") to the existing shareholders of Zelluna Immunotherapy AS. The fully committed private placement consisted of the issuance of 19,873,071 Offer Shares at a subscription price of NOK 2.60 per Offer Share, raising gross proceeds of approx. MNOK 51.7. Further, as part of the business combination between Zelluna Immunotherapy AS and Zelluna AS, cash at bank of MNOK 92.4 was acquired.
Total cash and cash equivalents were MNOK 135.3 per 31 March 2025.

Zelluna ASA and its subsidiaries (together the "Group") are focused on eliminating solid cancers by unleashing the most powerful elements of the immune system through pioneering the development of T cell receptor (TCR)-guided natural killer (NK) cell therapies.
Following a business combination transaction completed on 3 March 2025, these interim financial statements are presented in accordance with a reverse acquisition under IFRS 3 Business Combinations, where Zelluna Immunotherapy AS is identified as the accounting acquirer and Zelluna ASA as the accounting acquiree and listed parent company.
As a result of the reverse acquisition, the financial information presented for periods prior to the transaction reflects the operations, financial position, and cash flows of Zelluna Immunotherapy AS only. The historical operations of Zelluna ASA prior to the acquisition are not included in the financial information for periods before 1 March 2025.
Zelluna Immunotherapy AS is headquartered at the Oslo Cancer Cluster Innovation Park in Oslo, Norway, and is an active member of the Oslo Cancer Cluster and The Life Science Cluster.
Zelluna ASA is a public limited liability company listed on the Oslo Stock Exchange (Euronext Growth Oslo) under the ticker symbol "ZLNA".

The Group's presentation currency is NOK (Norwegian kroner).
These interim condensed financial statements have been prepared in accordance with IAS 34 Interim Financial Reporting. The accounting policies applied in the preparation of these financial statements are consistent with those followed in connection with the Company's 2024 financial statements. These condensed interim financial statements should therefore be read in conjunction with the 2024 financial statements.
The consolidated financial statements comprise the financial statements of Zelluna ASA and its two 100% owned subsidiaries, Zelluna Immunotherapy AS and Ultimovacs AB, as of the reporting date. On 3 March 2025, Zelluna ASA (the legal parent) completed a transaction with Zelluna Immunotherapy AS (the legal subsidiary). Although Zelluna ASA is the legal acquirer, the transaction has been accounted for as a reverse acquisition in accordance with IFRS 3 Business Combinations, with Zelluna Immunotherapy AS identified as the accounting acquirer and Zelluna ASA as the accounting acquiree. In accordance with IFRS 3.BC110, and for practical purposes, the Group has consolidated Zelluna ASA with effect from 1 March 2025. Management has assessed that the financial impact of consolidating from 1 March 2025 instead of the exact acquisition date of 3 March 2025 is immaterial to these interim financial statements. The acquisition date for accounting and measurement purposes remains 3 March 2025.
As a result of the reverse acquisition, the historical financial information presented for periods prior to the acquisition reflects the financial position, performance, and cash flows of Zelluna Immunotherapy AS.
These interim financial statements were approved for issue by the Board of Directors on 7 May 2025. The figures in the statements have not been audited.

The basic earnings per share are calculated as the ratio of the profit/loss for the period divided by the weighted average number of ordinary shares outstanding. In accordance with IAS 33 Earnings per Share and the guidance for reverse acquisitions under IFRS 3, basic and diluted earnings per share for are calculated as follows:
This approach reflects the fact that the legal parent became the listed entity after the acquisition, but the financial statements reflect the performance of the accounting acquirer throughout.
In line with IFRS 3 requirements for reverse acquisitions, the comparative figures in these consolidated financial statements represent the financial performance of the accounting acquirer only. Accordingly, the earnings per share for the comparative period is calculated based on:
This ensures comparability of earnings per share across periods on a consistent basis.
| NOK (000) | Q1-25 | Q1-24 | FY24 |
|---|---|---|---|
| Loss for the period | (28,349) | (32,779) | (105,162) |
| Average number of shares during the period ('000) | 77,491 | 14,938 | 15,074 |
| Earnings/loss per share (NOK) | (0.4) | (2.2) | (7.0) |
The share options issued to employees as a part of the Zelluna Employee Share Option Program have a potential dilutive effect on earnings per share. No dilutive effect has been recognized as potential ordinary shares only shall be treated as dilutive if their conversion to ordinary shares would decrease earnings per share or increase loss per share from continuing operations. As the Group is currently loss-making, an increase in the average number of shares would have anti-dilutive effects. Diluted and basic (undiluted) earnings per share are therefore the same.
Please see note 10 for more information regarding the option program.

In relation to the reverse share split, a share issue of 7 shares was necessary for the total number of shares to be divided by 10. Radforsk was the subscriber of these 7 shares.
As the updated number of shares was not registered in the share register VPS until 2 April 2025, the overview above does not reflect the reverse share split.

The main objectives of the share value-based incentive scheme are to align interests of shareholders and management/employees (value creation and risk taking) and ensure competitive compensation for management/employees and motivation to stay (retention).
The Zelluna ASA share option program was approved by the General Assembly on 2 May 2019 and the Board was authorized to increase the Group's share capital in connection with share incentive arrangement by up to 10% at the ordinary General Assembly held on 18 April 2024.

In addition, the majority of the employees in Zelluna Immunotherapy AS has a separate option program. No options in the Group are in the money, as the strike price is significantly higher than the current share price.
After the General Meeting, the option program for the employees in both Zelluna ASA and Zelluna Immunotherapy AS will be replaced by a new option program.
The new share option program will include all permanent employees in the Company. Vesting requires the option holder still to be an employee in the Company. Key parameters in the option program include the following:
The Zelluna Share Options' fair value is calculated according to the IFRS-2 regulations. Please see the Annual Report for more information regarding the calculation of the fair value and which parameters are used in the model.
Equity-settled share-based payments are measured at the fair value of the equity instruments at the grant date. Please see the Annual Report for more information regarding the accounting method of the options.

12. The Business combination between Zelluna Immunotherapy AS and Zelluna ASA
On 17 December 2024, Ultimovacs ASA ("Ultimovacs") and Zelluna Immunotherapy AS ("Zelluna") announced that Ultimovacs and shareholders of Zelluna representing more than 99% (later increased to 100%) of the total number of issued and outstanding shares in Zelluna (the "Selling Shareholders") had entered into a definitive Business Combination Agreement to combine the two companies in a share exchange transaction (the "Business Combination").
In connection with and conditional upon the Business Combination, Ultimovacs received precommitments for a private placement raising gross proceeds of approximately NOK 51.7 million by issuance of new shares at a subscription price of NOK 2.60 per Offer Share.
The Business Combination was approved at an Extraordinary General Meeting (EGM) of Ultimovacs held on 9 January 2025. The EGM also approved that the name of the Company following the Business Combination would be changed to Zelluna ASA. Completion of the Business Combination occurred in March 2025.

As part of the Transactions:
Although Zelluna ASA is the legal acquirer, the transaction has been accounted for as a reverse acquisition under IFRS 3 Business Combinations, with Zelluna Immunotherapy AS identified as the accounting acquirer and Zelluna ASA as the accounting acquiree.
As a result, the consolidated financial statements reflect the financial position, performance, and cash flows of Zelluna Immunotherapy AS prior to the acquisition date, with the results of Zelluna ASA being included from 1 March 2025, based on management's judgment that the difference to the actual completion date (3 March 2025) is immaterial, in accordance with IFRS 3.BC110.
The Business Combination was based on an agreed equity valuation of NOK 384.8 million for Zelluna Immunotherapy AS and NOK 89.5 million for Ultimovacs ASA (now Zelluna ASA), prior to the private placement. The valuation of Ultimovacs ASA corresponded to NOK 2.60 per share.
In accordance with IFRS 3, the consideration transferred in a reverse acquisition is based on the fair value of the shares deemed to have been issued by the accounting acquirer (Zelluna Immunotherapy AS) to the owners of the accounting acquiree (Zelluna ASA).
The consideration transferred is calculated as:

The table below summarizes the allocation of the consideration transferred:
| 28 Feb | |
|---|---|
| NOK (000) Unaudited | 2025 |
| ASSETS | |
| Property, plant and equipment | 23 |
| Right to use asset | 1,543 |
| Receivables and prepayments | 6,462 |
| Bank deposits | 93,314 |
| TOTAL ASSETS | 101,341 |
| LIABILITIES | |
| Accounts payable | 4,625 |
| Lease liability | 1,661 |
| Other current liabilities | 23,279 |
| Book value of equity 28 February 2025 | 71,776 |
| Total consideration (Purchase Price) | 75,005 |
| Excess value | 3,229 |
The net identifiable assets acquired reflect the book value of Zelluna ASA's equity at the acquisition date of MNOK 71.8.
The Purchase Price Allocation indicates that the consideration transferred exceeds the fair value of net assets acquired by approximately NOK 3.2 million. Considering the immaterial amount and subsequent market volatility, no goodwill has been recognized in the consolidated income statement as of 31 March 2025.
Had the acquisition of Zelluna Immunotherapy AS occurred on 1 January 2025, the combined entity would have reported pro forma revenue of MNOK 0 and a pro forma total loss of MNOK 35.2 for the period ended 31 March 2025.
The actual consolidated net loss for the period ended 31 March 2025 was MNOK 28.3, of which:
The pro forma information is presented for illustrative purposes only and does not purport to represent what the results of operations would actually have been if the acquisition had occurred on 1 January 2025, nor is it necessarily indicative of future results of operations. The pro forma loss reflects the alignment of accounting policies and includes adjustments for transaction-related expenses and amortization of acquired intangible assets, where applicable.
