The definitive Proxy Statement and other relevant documents will be mailed to stockholders of HeartSciences as of a record date to be established for voting on the Transactions and other matters as described in the Proxy Statement. HeartSciences will also file other documents regarding the Transactions with the SEC. This Current Report does not contain all of the information that should be considered concerning the Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, STOCKHOLDERS OF HEARTSCIENCES AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH HEARTSCIENCES' SOLICITATION OF PROXIES FOR THE SPECIAL MEETING OF ITS STOCKHOLDERS TO BE HELD TO APPROVE THE TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE PROXY STATEMENT BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT HEARTSCIENCES AND FORTITUDE AND THE TRANSACTIONS. Investors and security holders will also be able to obtain copies of the Proxy Statement and all other documents filed or that will be filed with the SEC by HeartSciences, without charge, once available, on the SEC's website at www.sec.gov.
