ALVO

Item 4 is hereby amended and supplemented as follows: On June 26, 2026, Celtic Lux purchased aggregate of 10,133,333 Ordinary Shares, at a price of $3.75 per share, for an aggregate investment of $38,000,000 (such investment, the "PIPE Investment") pursuant to the terms of a subscription agreement (the "Subscription Agreement") dated June 16, 2026, by and between Celtic Lux and the Issuer. In connection with the PIPE Investment, pursuant to the Subscription Agreement, Celtic Lux was granted registration rights pursuant to which Celtic Lux may, at any time and from time to time, make a written demand for registration under the Securities Act of 1933, as amended, of all or any portion of the shares purchased by it in the PIPE Investment on any available form of registration statement (a "Demand Registration"), including by way of an underwritten offering with underwriters selected by Celtic Lux and reasonably acceptable to the Issuer. The Issuer is obligated, using its reasonable best efforts and as expeditiously as possible after receipt of such demand, to prepare and file with the SEC a registration statement covering the resale of such shares and to keep such registration statement effective until all such shares have been disposed of or withdrawn. The Issuer is not obligated to effect more than two (2) Demand Registrations in total. The Issuer has the right to defer any Demand Registration for up to 60 days in total, or 30 consecutive days, in any 12-month period if the Issuer's board of directors determines in good faith that effecting the registration at that time would be materially detrimental to the Issuer and its shareholders. All costs and expenses incurred in connection with a Demand Registration are to be borne by the Issuer. The Issuer also agreed to provide customary indemnification to Celtic Lux in connection with its registration rights. The foregoing description of the PIPE Investment is qualified in its entirety by reference to the Subscription Agreement, which is filed as Exhibit 9 to this Amendment.
