("Clywedog") and Beacon Merger Sub, Inc. ("Merger Sub"), as described in the proxy statement/prospectus contained in the registration statement on Form S-4 (the "Registration Statement") to which this Exhibit 107 is attached. The number of shares of Topco Common Stock being registered under this line item is an estimate based on 40,848,893 Barinthus Ordinary Shares outstanding as of March 6, 2026. The value per share of securities to be received and maximum aggregate offering price are estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and 457(f)(1) under the Securities Act of 1933, as amended (the "Securities Act"). The offering price per share of securities to be received and maximum aggregate offering price used to determine the amount of the registration fee are based upon the average of the high and low prices of Barinthus ADSs, as reported on the Nasdaq Capital Market on March 25, 2026 ($0.5625), a date within five (5) business days prior to the filing of the Registration Statement ("Barinthus Value per Share"). The Maximum Aggregate Offering Price is estimated using the product of (i) the Barinthus Value per Share, multiplied by (ii) the estimated maximum number of Barinthus Ordinary Shares to be converted in the merger (40,848,893). Pursuant to Rule 416(a) of the Securities Act, the Registration Statement shall also cover any additional shares of Topco Common Stock that become issuable by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without receipt of consideration that increases the number of outstanding shares of Topco Common Stock.
