NOT FOR DISTRIBUTION OR RELEASE, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES, CANADA, AUSTRALIA, THE HONG KONG SPECIAL ADMINISTRATIVE REGION OF THE PEOPLE'S REPUBLIC OF CHINA OR JAPAN OR ANY OTHER JURISDICTION IN WHICH THE DISTRIBUTION OR RELEASE WOULD BE UNLAWFUL. OTHER RESTRICTIONS ARE APPLICABLE. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN. PLEASE SEE THE IMPORTANT NOTICE AT THE END OF THIS ANNOUNCEMENT.

Bergen, Norway and Oslo, Norway, 30 June 2025 – BerGenBio ASA (OSE: BGBIO) ("BerGenBio" or the "Company") and Oncoinvent ASA (OSE: ONCIN) ("Oncoinvent") announce that they have entered into a merger agreement (the "Agreement") to combine the two companies through a statutory merger (the "Merger"), where BerGenBio will be the acquiring entity. Following the Merger, the combined company shall carry out a fully underwritten rights issue.

The Merger puts BerGenBio’s capital and listing to productive use by strengthening Oncoinvent’s ability to execute on its clinical strategy and advance potentially life-changing treatments for patients with cancer in the abdominal cavity (peritoneal carcinomatosis).
The exchange ratio in the Merger will be 25% to BerGenBio and 75% to Oncoinvent corresponding to 1.20268049 shares in BerGenBio per share in Oncoinvent and values BerGenBio prior to the Merger at NOK 65 million, which represents a significant premium to what would be available for distribution to BerGenBio's shareholders in a solvent liquidation scenario, and a premium of 19% compared to the closing price on Monday 30 June 2025. The Merger values Oncoinvent at NOK 195.5 million, which corresponds to its valuation in connection with the listing on Euronext Growth in December 2024 and a premium of 8% compared to the closing price on Monday 30 June 2025.
The Merger will add approximately NOK 45 million in cash to fund Oncoinvent’s clinical development plan. Moreover, the combination will substantially broaden the shareholder base, improving liquidity in the share and enable an uplisting from Euronext Growth Oslo, subject to approval by the Oslo Stock Exchange.
Subject to approval by the extraordinary general meetings of BerGenBio and Oncoinvent, Euronext Oslo Børs’ approval of the continued listing and completion of the Merger, the merged company will carry out a fully underwritten rights issue of NOK 130 million (the "Rights Issue"). The proceeds from the Rights Issue is expected to provide the merged company with a cash runway into 2027, beyond the interim readout from Oncoinvent’s ongoing Phase 2 trial in ovarian cancer, expected H2 2026.
The Merger is supported by BerGenBio’s largest shareholder Meteva AS and Oncoinvent’s largest shareholders Hadean Capital I AS and HVentures Capital I AB (together "Hadean Ventures") and Linc AB, all of whom have entered into voting undertakings to vote in favour of the Merger and lock-up commitments for a period of six months following this announcement.

The Agreement follows from the strategic review that BerGenBio has conducted, in cooperation with DNB Carnegie, to optimise shareholder value following its decision to discontinue the BGBC016 study.

Anders Tullgren, chair of the board of BerGenBio, stated: “I am very pleased to be able to announce our joining forces with Oncoinvent. This Merger, which is backed by the boards of both companies, is the result of an extensive review that explored a range of strategic options for BerGenBio. The Merger gives BerGenBio shareholders a part of an exciting company leveraging Norwegian radiopharmaceutical technology, which has already seen encouraging preliminary efficacy data, without safety concerns. We are confident that this is the best option for current BerGenBio shareholders.”

Øystein Soug, CEO of Oncoinvent and forthcoming CEO of the merged company, stated: “We are very excited for the time ahead and to continue the execution of our focused strategy to develop Radspherin® in ovarian cancer. We are on track with our randomised phase 2 trial. Going forward with a strengthened balance sheet, we believe the company will be a transformative force in the radiopharmaceutical therapy field, improving the lives of patients with cancer in the peritoneal cavity.”

About Oncoinvent

Oncoinvent is a clinical-stage biotechnology company developing novel radiopharmaceutical therapies against cancer. The lead product candidate, Radspherin®, uses the alpha-emitting radionuclide radium-224, directly targeting micro-metastases post-surgery, harnessing the benefits of modern radiopharmaceuticals without the complexities of biological targeting.

Oncoinvent is investigating the safety and efficacy of Radspherin® in a clinical development program in two indications: peritoneal metastases from colorectal cancer and from ovarian cancer. In addition to the recently finalized phase 1/2a trial in colorectal cancer, one phase 1 trial and one randomized phase 2 trial are ongoing in the US, UK and Europe. Interim data from the phase 2 trial are expected in H2 2026. Preliminary clinical efficacy data are highly encouraging, and no serious toxicity or safety concerns have been reported to date.

The experienced Oncoinvent team runs a state-of-the-art manufacturing facility to produce drug products for clinical trials in Nydalen, Oslo. Oncoinvent is listed on the Euronext Growth Oslo. The company was founded by Øyvind Bruland and Roy Larsen, the pioneers behind Norway’s most successful cancer drug to date, Xofigo, developed by the company Algeta, which was acquired by Bayer in 2014.

The Merger and Exchange ratio

The Merger is structured as a statutory merger whereby all assets and liabilities of Oncoinvent will be transferred to a newly incorporated wholly owned subsidiary of BerGenBio against consideration to the shareholders in Oncoinvent by way of newly issued shares in BerGenBio and with BerGenBio as the surviving entity. The exchange ratio in the Merger will be 1:3, meaning that Oncoinvent shareholders will in total receive approximately 117.6 million BerGenBio shares, corresponding to approximately 1.20268049 BerGenBio shares per Oncoinvent share.

Rights Issue

The combined company will carry out a fully underwritten rights issue of shares (the "New Shares") with preferential subscription rights for existing shareholders in the merged company upon completion of the Merger to raise gross proceeds of NOK 130 million.

Both Oncoinvent’s and BerGenBio’s shareholders at the time of completion of the Merger will, subject to restrictions in applicable securities laws and regulations, be invited to participate in the Rights Issue, which ensures equal treatment of all shareholders. By exercising their subscription rights, each shareholder will have the opportunity to maintain their pro rata ownership in the merged company. If all shareholders participate, the resulting ownership structure will reflect a 25/75 ratio, with BerGenBio shareholders upon completion of the Merger owning 25% and Oncoinvent shareholders upon completion of the Merger owning 75% of the merged company.

Certain existing shareholders and external investors (the “Underwriters") have, subject to customary terms and conditions, underwritten NOK 130 million of the Rights Issue, representing 100 percent of the total offering amount. The proceeds from the Rights Issue are expected to provide the merged company with a cash runway into 2027. Further information regarding the fully underwritten Rights Issue, including the terms and conditions, the subscription period, key dates, and procedures for subscription, is available in a separate stock exchange announcement published by the Company on the same date as this release. Shareholders are encouraged to review the announcement carefully for complete details on how to participate in the Rights Issue.
