Item 4. Purpose of Transaction.

Business Combination

On September 14, 2022, the Issuer entered into a Business Combination Agreement (amended by an Amendment to Business Combination Agreement dated as of February 9, 2023,), by and among the Issuer, Maxpro, and Merger Sub. Pursuant to the Business Combination Agreement, the Merger Sub merged with and into Maxpro, with Maxpro continuing as the surviving company (the “Merger”) and becoming a wholly-owned subsidiary of the Issuer (the transactions contemplated by the Business Combination Agreement, the “Business Combination”). The Business Combination was consummated on March 29, 2023.

As part of the Business Combination, each of the preferred shares of the Pre-Closing Issuer, par value $0.0001 per share (the “preferred shares”), was converted into one ordinary share of the Pre-Closing Issuer, par value $0.0001 per share (the “ordinary shares”), and each ordinary share of the Pre-Closing Issuer was converted into a number of Class B Ordinary Shares of the Issuer. Additionally, pursuant to the Business Combination Agreement and MAA, the composition of the Class B Ordinary Shares issued in exchange of the Pre-Closing Issuer ordinary shares was adjusted by the Board to increase the number of registered and tradeable Class A Ordinary Shares in the Issuer’s public float at the time of the closing of the Business Combination (March 29, 2023, the “Closing”). As a result, at the Closing, the ordinary shares and preferred shares held by the Reporting Person in the Pre-Closing Issuer were converted into an aggregate of 191,655 Class A Ordinary Shares and 4,955,400 Class B Ordinary Shares.

On September 29, 2023, the 4,955,400 Class B Ordinary Shares held by Dr. Guo-Liang Yu automatically converted into 4,955,400 Class A Ordinary Shares pursuant to the Issuer’s MAA.

In determining whether to carry out any of the above-mentioned actions, the Reporting Person may consider factors such as the Issuer’s financial position and strategic direction, actions taken by the Board, price levels of the Class A Ordinary Shares, conditions in the securities market and general economic and industry conditions.
