Explanation of Responses:

1. The sole holder of Wave's Series A preferred shares, SNBL USA, Ltd. ("SNBL USA") and Shin Nippon Biomedical Laboratories, Ltd. ("SNBL"), elected to convert its Series A preferred shares into ordinary shares on a one-for-one basis on March 23, 2026. Due to processing issues among the Issuer's vendors, complicated by the time difference with Singapore, the date of the conversion was not confirmed to be effective until well after March 23, 2026.

2. Includes (i) 2,100,000 shares held by SNBL USA and (ii) 1,801,348 shares held by SNBL.

3. Includes an aggregate of (i) 6,107,593 shares held by SNBL USA and (ii) 3,498,815 shares held by SNBL.

4. Ken Takanashi, a director of the Issuer, is a director of SNBL USA and SNBL and Mr. Takanashi may be deemed to beneficially own the reported securities held by SNBL USA and SNBL. Pursuant to Rule 16a-1 under the Securities Exchange Act of 1934, as amended (the "Act"), Mr. Takanashi disclaims beneficial ownership of the reported securities held by SNBL USA and SNBL, except to the extent of his pecuniary interest therein. The filing of this Form 4 shall not be construed as an admission that Mr. Takanashi is or was for the purposes of Section 16(a) of the Act, or otherwise, the beneficial owner of any of the reported securities held by SNBL USA or SNBL.
