Health Assurance Acquisition Corp. (HAACW) operates as a blank check company whose public shares were redeemed and the entity liquidated in November 2022 after failing to complete an initial business combination; its warrants (HAACW), exercisable at $11.50 per share, expired worthless with no distributions to holders. Incorporated in 2020 and headquartered in Cambridge, Massachusetts, the company previously focused on effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses in the health assurance sector, particularly innovators leveraging technology for healthcare platforms; it offered no products or services beyond this SPAC structure. The company changed its name from Healthcare Assurance Acquisition Corp. in October 2020 and launched a $500 million initial public offering in November 2020 via Stakeholder Aligned Initial Listing (SAIL) securities, led by CEO Hemant Taneja with backing from General Catalyst. In October 2022, HAAC announced redemption of all public shares at approximately $10.05 per share from its trust account, ceased operations except for wind-up activities by November 3, 2022, delisted from Nasdaq, and fully liquidated, returning funds to public shareholders while sponsor shares were waived; no merger target was identified within the 24-month tenor despite targeting health tech opportunities.
