ZURICH, SWITZERLAND – June 10, 2026 — VERAXA Biotech AG, an emerging leader in designing novel cancer therapies, today announced that its previously announced business combination (“Business Combination”) with Voyager Acquisition Corp. (NASDAQ:VACH, “Voyager”), a special purpose acquisition company sponsored by Cantor Fitzgerald & Co., Voyager Acquisition Sponsor Holdco LLC, and Odeon Capital Group LLC, was closed successfully (the “Closing”). Pursuant to the Closing, VERAXA Biotech AG and Voyager merged with and into VERAXA Biotech Holding AG, which will change its name to VERAXA Biotech AG (NASDAQ: VRXA; “VERAXA”). The shareholders of Voyager approved the transaction on March 12, 2026. The transaction had been previously approved by VERAXA’s shareholders on February27, 2026. Tomorrow, on June 11, 2026, VERAXA will commence trading its shares under the symbol “VRXA” and its warrants under the symbol “VRXAW” on the Nasdaq Capital Market.

VERAXA is developing a new generation of bispecific TCEs and ADCs aimed at increasing patient benefit through enlarging the therapeutic window and maximizing safety and efficacy. Central to VERAXA’s strategy is the use of its proprietary technology platform BiTAC (Bi-targeted Tumor-Associated Cytotoxicity),which enables the creation of conditionally activated, AND-gated therapeutic strategies that precisely target cancer cells while leaving healthy cells intact. This highly specific dual-antigen approach targets tumor cells with precision and makes it possible to target solid tumors with non-exclusive cancer markers. VERAXA is currently advancing a pipeline of development programs with a focus on solid tumors, which are predominantly sourced from its BiTAC platform. VERAXA’s BiTAC platform also enables the company to contribute value to developments in complementary therapeutic sectors such as radioimmunoconjugates (RICs) and antibody-oligonucleotide conjugates (AOCs).

Initial data from VERAXA’s most advanced BiTAC program were presented at the recent American Association for Cancer Research(AACR) Annual Meeting 2026 in San Diego, CA, USA.  VERAXA’s BiTAC-TCE candidate performed as intended in vitro and in vivo, attacking cancer cells featuring both target molecules while sparing cells expressing just one of these targets. Data demonstrated a superior safety profile and matching efficacy compared to a more traditional TCE, pointing to the possibility of a significantly improved therapeutic index. The Company’s posters are available on the VERAXA website at www.veraxa.com.  

Proceeds from the financings will provide VERAXA with the ability to advance its pipeline of BiTAC-TCE and BiTAC-ADC programs toward clinical development and through initial value inflection points. The financings are comprised of a senior secured note in the principal amount of $27.5 million and a securities purchase agreement of up to $50 million.

“Entering this next chapter as a public company with significant momentum is a transformational milestone for VERAXA,” said Christoph Antz, Ph.D. Chief Executive Officer of VERAXA. “We are grateful for the support received to date from current and new shareholders as the completion of our business combination better positions us to deliver meaningful value to patients with cancer. From here, we look to fully unlocking the transformative therapeutic potential of our BiTAC-TCE and BiTAC-ADC programs and establish our BiTAC platform as a launch pad for a multitude of innovative cancer therapies.”

“VERAXA combines strong technology, excellent science, and an experienced management team – the ideal foundation for sustainable success on an international scale,” added Oliver R. Baumann, Chairman of the VERAXA Board and CEO of Xlife Sciences AG. “Bringing our first portfolio company onto the NASDAQ market and setting VERAXA up for the accelerated growth of its pipeline and organization is a significant milestone for VERAXA and for Xlife Sciences at the same time.”

“New technologies are poised to unlock significant value in two of the most vibrant subsectors in cancer medicine in recent years – bispecific T-cell engagers and ADCs,” said Warren Hosseinion, M.D., Chairman of the Voyager Board of Directors prior to the Closing of theBusiness Combination and a current member of the VERAXA Board of Directors. “In VERAXA, we have found a unique opportunity to fulfill Voyager’s mission of scaling a transformational approach in the healthcare industry toward clinical readiness and market approval.”
