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 February 27, 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 the Business 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."

Non-Solicitation

This press release is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the potential transaction and shall not constitute an offer to sell or a solicitation of an offer to buy the securities of Voyager or VERAXA, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended.

Forward-Looking Statements

This press release includes certain statements that may be considered forward-looking statements within the meaning of the federal securities laws. Forward-looking statements include, without limitation, statements about future events or Voyager's or VERAXA's future financial or operating performance. For example, statements regarding VERAXA's anticipated growth and the anticipated growth and other metrics, statements regarding the benefits of the Business Combination, and the anticipated timing of the completion of the Business Combination are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as "may," "should," "could," "might," "plan," "possible," "project," "strive," "budget," "forecast," "expect," "intend," "will," "estimate," "anticipate," "believe," "predict," "potential" or "continue," or the negatives of these terms or variations of them or similar terminology.

These forward-looking statements regarding future events and the future results of Voyager and VERAXA are based on current expectations, estimates, forecasts, and projections about the industry in which VERAXA operates, as well as the beliefs and assumptions of Voyager's management and VERAXA's management. These forward-looking statements are only predictions and are subject to, without limitation, (i) known and unknown risks, including the risks and uncertainties indicated from time to time in the final prospectus of Voyager relating to its initial public offering filed with the SEC, and in the proxy statement/prospectus filed by Voyager and VERAXA on February 19, 2026, including those under "Risk Factors" therein, and other documents filed or to be filed with the SEC by Voyager; (ii) uncertainties; (iii) assumptions; and (iv) other factors beyond Voyager's or VERAXA's control that are difficult to predict because they relate to events and depend on circumstances that will occur in the future. They are neither statements of historical fact nor promises or guarantees of future performance. Therefore, VERAXA's actual results may differ materially and adversely from those expressed or implied in any forward-looking statements and Voyager and VERAXA therefore caution against relying on any of these forward-looking statements.

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Voyager and its management and VERAXA and its management, as the case may be, are inherently uncertain and are inherently subject to risks, variability and contingencies, many of which are beyond Voyager's or VERAXA's control. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (i) the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement and any subsequent definitive agreements with respect to the Business Combination; (ii) the outcome of any legal proceedings that may be instituted against Voyager, VERAXA, or others following the announcement of the Business Combination and any definitive agreements with respect thereto; (iii) the inability to complete the Business Combination due to the failure to obtain consents and approvals of the shareholders of Voyager, to obtain financing to complete the Business Combination or to satisfy other conditions to closing, or delays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals required to complete the transactions contemplated by the Business Combination Agreement; (iv) the failure to realize estimated shareholder redemptions, purchase price and other adjustments; and (v) other risks and uncertainties set forth in the filings by Voyager with the SEC. There may be additional risks that neither Voyager nor VERAXA presently know or that Voyager and VERAXA currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Any forward-looking statements made by or on behalf of Voyager or VERAXA speak only as of the date they are made. None of Voyager or VERAXA undertakes any obligation to update any forward-looking statements to reflect any changes in their respective expectations with regard thereto or any changes in events, conditions or circumstances on which any such statement is based.
