Lakeshore Acquisition I Corp. (LAAAW) operates as a blank check company, or special purpose acquisition company (SPAC), whose sole purpose is to effect a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization, or similar business combination with one or more businesses or entities; it conducts no significant operations prior to completing such a transaction. Incorporated in 2021 as a Cayman Islands exempted company and headquartered in Shanghai, China, with certain references to New York, NY operations, the company raised $50 million in its initial public offering in June 2021 through 5 million units at $10 each, consisting of one ordinary share and three-quarters of one redeemable warrant each exercisable at $11.50 per whole share; the warrants trade separately under the LAAAW ticker on Nasdaq Capital Market. In December 2022, Lakeshore completed its business combination with ProSomnus Sleep Technologies, Inc., a developer of precision-custom intraoral medical devices for treating obstructive sleep apnea; post-merger, the combined entity operates as ProSomnus, Inc. (Nasdaq: OSA), with Lakeshore's ordinary shares and units delisted and suspended from trading, while LAAAW warrants persist as legacy securities exercisable into ProSomnus common stock upon meeting post-combination conditions. The transaction, initially announced in May 2022 for an enterprise value of approximately $168 million including debt assumption and backed by $30 million in convertible notes from Cohanzick Management and CrossingBridge Advisors, received shareholder approval on December 2, 2022, following a three-month extension secured in September 2022; no subsequent major changes, new funding, or further combinations involving Lakeshore or LAAAW have been reported as of late 2025.
