Siena (Italy), March 27, 2026 – The Board of Directors of Philogen S.p.A. (the “Company” or “Philogen”) and, together with its Swiss subsidiary Philochem AG (the “Group”), meeting today under the chairmanship of Dr. Duccio Neri, approved the draft financial statements and consolidated financial statements as of December 31, 2025, prepared in accordance with IAS/IFRS international accounting standards.

Dario Neri, CEO of Philogen, commented on the results for the year and the performance of the business:

“2025 was a year of excellent financial results for Philogen, with a record profit and revenues that were quadrupled compared to 2024. The significant cash position available to the Group allows it to expand the program portfolio and to further strengthen the various corporate functions, from research to production.

On the clinical front, we have further expanded our pipeline, both in antibody-based drugs and in small organic molecules. In 2026 and 2027, seven new studies with registrational potential have been or will be initiated, confirming the Group's strong commitment to developing its pipeline and advancing its candidates toward potential registration in the near future. We also expect the initiation of seven new Phase I clinical studies on new experimental drugs.

The growth of the pipeline represents tangible evidence of the Philogen Group's ability to discover new products, leveraging excellence in discovery platforms (e.g., encoded combinatorial libraries), and bringing them rapidly into clinical development at the highest regulatory standards. Finally, we are strengthening our technological capabilities through the expansion of the team dedicated to artificial intelligence, with the aim of increasing operational efficiency and accelerating the development of new drugs.”

CONSOLIDATED FINANCIAL STATEMENTS AS OF DECEMBER 31, 2025

PRESS RELEASE

The Group's total revenue amounted to €320,121 thousand, representing an increase of approximately €242,468 thousand compared with the financial year ended 31 December 2024, and comprises (i) Revenue from contracts with customers of €314,325 thousand, a sharp increase (approximately 325%) compared with the previous year, and (ii) Other income of €5,796 thousand, an increase of approximately 60% compared with the previous year.

The increase in the item 'Revenue from contracts with customers' is primarily attributable to the payment of the upfront fee accrued following the entry into force of the licence agreement signed by the subsidiary Philochem AG with RayzeBio, a company of the Bristol Myers Squibb group, concerning OncoACP3, a therapeutic and diagnostic candidate for the treatment of prostate cancer. In particular, following the completion of the antitrust approval process in the United States, the agreement came into effect in August 2025, giving rise to the right to receive the initial payment provided for in the contract. This agreement generated revenue of approximately €300,000 thousand. Furthermore, progress continues on research and development projects linked to contracts entered into with certain customers, as well as on the third-party production contracts that the Group is developing.

The Group does not yet have any products on the market; therefore, revenues are not yet linked to stable turnover. In line with the Group's business model, which operates in the biotech sector, the income statement reflects upfront payments, milestone payments, and the progress of collaboration contracts with third parties. In particular, it should be noted that, as previously disclosed to the market, the licence agreement executed in 2025 with RayzeBio (BMS Group) provides, in addition to the USD 350 million upfront payment received in 2025, for milestones up to USD 1 billion and royalties ranging from the mid-single to low double-digit percentage range payable on global net sales.

The item 'Other Income' recorded an increase of €2,138 thousand attributable almost entirely to operating grants linked to the tax credit for pharmaceutical research and development, from which the Group benefits on an ongoing basis by virtue of its core business activities.

Operating costs, amounting to €58,488 thousand, an increase of €22,453 thousand compared with the financial year ended 31 December 2024, consist mainly of costs for production materials, costs for clinical and preclinical services, staff costs and other operating costs. This change is attributable to (i) the increase in costs for materials, which rose from €3,092 thousand as of 31 December 2024 to €5,305 thousand as of 31 December 2025, (ii) the increase in costs for services related to the Group's core business activities, which for the current year include consultancy costs and brokerage fees linked to the contract with RayzeBio, rising from €16,483 thousand as at 31 December 2024 to €34,262 thousand as at 31 December 2025, and (iii) the increase in staff costs, which rise from €15,623 thousand as at 31 December 2024 to €17,885 thousand as at 31 December 2025.

EBITDA increased by approximately €220,014 thousand, rising from a positive figure of €41,618 thousand as of 31 December 2024 to a positive figure of €261,633 thousand as of 31 December 2025, as a result of the 312% increase in total revenue and the 62% increase in operating costs.

Depreciation and amortisation increased by approximately 9% compared with the previous financial year, rising from €3,887 thousand as of 31 December 2024 to €4,256 thousand as of 31 December 2025, due to the full utilisation of machinery and plant, capital expenditure (Capex) investments made during 2025 and the amortisation of improvements to third-party assets.

EBIT, calculated as the difference between EBITDA and depreciation and amortisation, shows a positive balance of €257,377 thousand for the financial year ended 31 December 2025, compared with a positive balance of €37,731 thousand as of 31 December 2024.

Net financial results for the year ended 31 December 2025 show a net profit of €2,736 thousand, compared with a net profit of €2,644 thousand for the year ended 31 December 2024. The net profit for the year is mainly attributable to (i) net gains on the valuation of financial assets at fair value amounting to €607 thousand, (ii) net proceeds from the disposal of financial assets amounting to €3,457 thousand, (iii) net interest income of €1,018 thousand and (iv) a negative net foreign exchange effect of €2,343 thousand.

Taxes, amounting to €30,432 thousand, represent the net balance between current and deferred taxes and are attributable, to the extent of €30,988 thousand, to the tax estimate made on the profit for the year recorded by the subsidiary Philochem AG.

The profit for the year ended 31 December 2025 amounts to €229,681 thousand, an increase compared to the profit as at 31 December 2024, which stood at €45,292 thousand.

The table below shows the Philogen Group's Net Financial Debt as at 31 December 2025, prepared in accordance with ESMA Guideline 32-382-1138 of 4 March 2021 and Consob's Advisory Note No. 5/21:

It should also be noted that a portion of the cash and cash equivalents, amounting to €72,416 thousand as of December 31, 2025, is invested in short-term time deposits, which bear interest at market rates upon maturity.

Current and non-current financial debt decreased from €11,182 thousand as of September 30, 2025 to €10,927 thousand as of December 31, 2025, representing a decrease of approximately €255 thousand resulting from the progress of the amortization schedules for outstanding loans. Current and non-current financial debt consists entirely of debt related to the right-of-use of properties (IFRS 16). It should be noted that during 2025, ISTAT adjustments were made to property rents, which were affected by the high inflation rate during that period.

PRESS RELEASE

MAJOR EVENTS OCCURRING AFTER THE END OF THE FISCAL YEAR

In January 2026, the Group's two GMP-certified pharmaceutical manufacturing facilities were inspected by AIFA. Specifically, at the Montarioso facility, the GMP MED (Medicines) inspection took place between January 12, 2026 and January 19, 2026, and the GMP API (Active Pharmaceutical Ingredients) inspection from January 12, 2026 to January 15, 2026. At the Rosia facility, the GMP MED (Medicines) inspection took place from January 12, 2026 to January 16, 2026.

The inspections conducted by the GMP Medicines Office of the Italian Medicines Agency (AIFA) at the Philogen S.p.A. pharmaceutical facility in Rosia concluded with a positive outcome, with the issuance of the corresponding inspection report; the improvement measures suggested by the regulatory authority in the aforementioned report are currently being implemented.

The inspections conducted by the Medicinal Products GMP Office and the API GMP Office of the Italian Medicines Agency (AIFA) at the Philogen S.p.A. pharmaceutical plant in Montarioso (more specifically, the General GMP Inspection for medicinal products and the inspection aimed at reactivating the site following the completion of the revamping of the production areas for API GMP), were concluded successfully, with the issuance of the relevant inspection reports. The improvement measures indicated by the regulatory authorities in the aforementioned reports are currently being implemented.

Furthermore, during 2026, the Company continued to closely monitor the performance of the U.S. dollar and its exchange rate against the Euro, favorably leveraging fluctuations to manage the perceived high currency risk following the receipt of the upfront payment under the contract with RayzeBio, which was denominated in dollars. As of the date of this report, currency exposure is not considered significant.

Finally, the share buyback program launched in December 2024 continued throughout 2026.

FORECAST BUSINESS OUTLOOK

The Group reports the following main industrial milestones achieved during the period:

Proprietary products

1) Antibody-based products:

  • Nidlegy™ – biopharmaceutical product developed for the treatment of skin cancers

Following the withdrawal in 2025 of the Marketing Authorization Application previously submitted to the EMA for the melanoma indication, the Company is working on the preparation of a new submission in Europe during the current year.

In the United States, a Phase III clinical trial in locally advanced melanoma is ongoing, and is currently active also in Spain and Switzerland, with planned expansion to additional countries. In March 2026, a Type C meeting was held with the U.S. Food and Drug Administration (FDA), during which data from the European study were presented and alignment was reached on the regulatory pathway aimed at obtaining approval in melanoma in the United States, subject to the completion and positive outcome of the ongoing study.

Within the non-melanoma skin cancer (NMSC) program, the Phase II "Duncan" study has been completed in patients with basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). The excellent results in BCC were presented at the European Society for Medical Oncology (ESMO) 2025 conference reporting complete pathological responses in 52.6% of patients. Full results from the BCC and cSCC will be published in 2026.

The Phase II "Intrinsic" study is currently ongoing, with a target of 70 patients affected by various forms of NMSC; to date, 65 patients have been treated in Italy and France.

The very positive results observed in the "Duncan" and "Intrinsic" trials have provided a strong rationale for the initiation of three new registrational studies in these indications in Europe and the United States, in BCC and cSCC. The design of these studies has already been discussed with the relevant regulatory authorities, and the enrolment of the first patients is expected in the second quarter of 2026.

PRESS RELEASE

An additional Scientific Advice with the FDA has also been completed to define a fourth registrational study in first-line BCC, in which the performance of $\mathrm{Nidleyy}^{\mathrm{TM}}$ will be compared with Hedgehog pathway inhibitors (HHI); the start of the study is expected in mid-2026.

An additional Scientific Advice with the FDA has also been completed to define a fourth registrational study in first-line BCC, in which the performance of $\mathrm{Nidleyy}^{\mathrm{TM}}$ will be compared with Hedgehog pathway inhibitors (HHI); the start of the study is expected in mid-2026.

Fibromun – STS and Glioblastoma

Following the results of the FIBROSARC study in first-line soft tissue sarcoma, which showed encouraging signals in terms of survival in patients with liposarcoma and other sarcoma types, a request for Parallel Scientific Advice with the FDA and EMA has been submitted to define the design of a new Phase III registrational study (FIBROSARC-2). The conclusion of the process is expected in the second quarter of 2026, after which the study is planned to start (i.e., with the submission of the clinical trial application), with overall survival as the primary endpoint. The rationale for this program is further supported by the observation of complete remissions in patients treated with Fibromun in combination with doxorubicin.

The Phase II FLASH study in last-line soft tissue sarcoma enrolled 94 patients randomised 1:1 to receive either Fibromun + dacarbazine or dacarbazine alone. The study did not meet the primary endpoint for Progression Free Survival (PFS). Pretreated soft tissue sarcoma remains a highly challenging disease with significant unmet medical need. The company remains committed to advancing innovative therapeutic approaches with the goal of improving outcomes for soft tissue sarcoma patients.

With regard to glioblastoma studies, the Phase II GLIOSTAR clinical trial conducted in 163 second-line patients did not meet its primary endpoint. Despite the high unmet medical need, this indication remains extremely challenging, as other drugs (VEGF blockers, antibody-drug conjugates, anti-PD1 antibodies) have also failed to demonstrate an improvement in patient survival. However, in GLIOSTAR, an improvement in survival was observed in the subgroup of patients with only limited previous exposure to alkylating agents.

The Company remains committed to the execution of the GLIOSUN clinical trial, conducted in treatment-naïve glioblastoma patients (i.e., first-line) and therefore not previously exposed to alkylating agents. GLIOSUN has completed the dose escalation phase and is initiating the subsequent dose expansion phase.

Finally, the GLIOSTELLA study, conducted in last-line glioblastoma patients, has completed patient enrolment in the United States and is expected to report survival data in September 2026.

2) Small-molecule products

OncoFAP – FAP Platform

This is a small molecule with very high affinity for fibroblast activation protein. The product is suitable for diagnostic and therapeutic applications for various solid tumors.

The diagnostic study $^{68}\mathrm{Ga}$ -OncoFAP has completed Phase I (solid tumors).

The Phase I therapeutic study $^{177}\mathrm{Lu}$ -OncoFAP-23 (solid tumors) is continuing with encouraging results.

The OncoFAP-GlyPro-MMAE conjugate has demonstrated marked antitumor activity in both preclinical studies and a Phase I veterinary clinical trial conducted at the University of Milan. A substantial reduction in disease was reported in six out of seven treated animal patients. GMP manufacturing is underway in preparation for the start of clinical trials in 2027. Additionally, a new immunotherapy candidate based on the OncoFAP ligand is showing promising signs of efficacy in a Phase I veterinary study. These results lay the groundwork for the expansion of the future pipeline based on small molecule drug conjugates.

OncoACP3 – PAP target (prostate)

This is a small molecule with very high affinity for the Prostatic Acid Phosphatase protein. The product is suitable for diagnostic and therapeutic applications for prostate cancer.

PRESS RELEASE

NOTICE OF THE ANNUAL GENERAL MEETING OF SHAREHOLDERS TO BE HELD ON 29 APRIL 2026

The Board of Directors of Philogen has resolved to convene the Annual General Meeting of Shareholders, in a single call, on 29 April 2026.

The Shareholders' Meeting will be called upon to deliberate (i) on the approval of the financial statements for the year ended 31 December 2025, (ii) on the allocation of the profit for the 2025 financial year, (iii) on the distribution of a dividend to be drawn from available reserves, (iv) on the first section (binding resolution) and the second section (non-binding resolution) of the Report on Remuneration Policy and Remuneration Paid, prepared in accordance with Article 123-ter of Legislative Decree No. 58 of 24 February 1998, and (v) on the authorisation to purchase and dispose of treasury shares, subject to the revocation of the authorisation granted by the Shareholders' Meeting of 29 April 2025 for the unexecuted portion.

The notice of meeting and the relevant summary are published in accordance with the timeframes and procedures laid down by current legislation.

ALLOCATION OF THE NET PROFIT FOR THE FINANCIAL YEAR

Allocation of the Net Profit for the Financial Year

As mentioned above, Philogen's draft financial statements show a net profit for the 2025 financial year of €229,680,710.49.

Given that the Company's net profit for the financial year derives entirely from the value of its investment in the subsidiary Philochem AG, recorded in the financial statements as at 31 December 2025 at a value of €251,622,464.33, and that it is therefore necessary, in accordance with the law, to establish a restricted equity reserve of an equivalent value, the Board of Directors has resolved to propose to the Shareholders' Meeting convened for 29 April 2026 that:

  • to allocate the net profit for the current financial year, amounting to €229,680,710.49, to the restricted reserve arising from the valuation of equity investments;
  • to allocate to the aforementioned restricted reserve arising from the valuation of equity investments, in addition:

(i) a portion of the "Retained earnings/(losses)" reserve amounting to €12,463,463.35; and
(ii) a portion of the "Share premium" reserve amounting to €9,478,290.49;

Consequently, the three provisions will together amount to the value of the investment in the subsidiary Philochem AG, which is recognised in the financial statements as of 31 December 2025 at €251,622,464.33.

Proposal to pay a dividend of €0.70 per share

The Board of Directors – on the assumption that the Shareholders' Meeting adopts the above-mentioned resolutions regarding the allocation of the net profit for the current financial year and the proposed provisions – has resolved to propose to the Shareholders' Meeting convened for 29 April 2026 the distribution, from the “Retained earnings/(losses)”, a dividend per share of €0.70, gross of statutory withholding tax, for each Philogen share entitled to dividends as at the ex-dividend date (net, therefore, of any treasury shares held in the portfolio), for an estimated total amount of €28,180,796 (it being understood that the final total amount actually allocated to the payment of the dividend will be calculated on the basis of the number of shares entitled to dividends on the ex-dividend date).

The Board of Directors has proposed that the dividend be paid from 20 May 2026, with a record date of 19 May 2026 and an ex-dividend date of 18 May 2026.

Proposal to authorise the purchase and disposal of treasury shares

The Board of Directors has resolved to propose to the Shareholders' Meeting, subject to the revocation of the authorisation granted by the Shareholders' Meeting on 29 April 2025 in respect of the unexecuted portion, that the Shareholders' Meeting

Description of the Philogen Group

Philogen is an Italian-Swiss company operating in the biotechnology sector, specializing in the research and development of pharmaceutical products for the treatment of highly lethal diseases. The Group primarily discovers and develops targeted anticancer drugs, utilizing high-affinity ligands for tumor markers (also known as tumor antigens). These ligands—human monoclonal antibodies or small organic molecules—are identified using Antibody Phage Display Libraries and DNA-Encoded Chemical Libraries technologies.

The Group's primary therapeutic strategy for treating these diseases is tumor targeting. This approach relies on the use of ligands capable of selectively delivering highly potent therapeutic agents (such as pro-inflammatory cytokines) to the tumor mass while sparing healthy tissues. Over the years, Philogen has primarily developed ligands based on monoclonal antibodies, specific for antigens expressed in blood vessels associated with tumors but not expressed in blood vessels associated with healthy tissues. These antigens are typically more abundant and more stable than those expressed directly on the surface of tumor cells. This approach, known as vascular targeting, is used in most of the projects pursued by the Group.

The Group's objective is to generate, develop, and commercialize innovative products for the treatment of diseases for which medical science has not yet identified satisfactory therapies. This is made possible by leveraging (i) proprietary technologies for isolating ligands that bind to antigens present in specific diseases, (ii) expertise in developing products targeted at tissues affected by the disease, (iii) expertise in drug manufacturing and development, and (iv) a broad portfolio of patents and intellectual property rights.

Although the Group's drugs are primarily used in oncology, the targeting approach is potentially applicable to other conditions as well, such as certain chronic inflammatory diseases.

(
*) EBITDA represents operating profit before depreciation and amortization. EBITDA is a measure defined and used by the Group to monitor and evaluate the Group's operating performance, but it is not defined under IFRS; therefore, it should not be considered an alternative measure for evaluating the Group's operating performance. The Company believes that EBITDA is an important metric for measuring the Group's performance as it allows for an analysis of the Group's profitability by eliminating the effects of non-recurring economic items. Since EBITDA is not a measure whose calculation is regulated by the accounting standards applicable to the preparation of the Group's consolidated financial statements, the method used to calculate EBITDA may not be consistent with that adopted by other groups, and therefore may not be comparable.
