EXPLANATORY NOTE

Lucas GC Limited, a Cayman Islands exempted company (the “Company” or the “Registrant”), is filing this post-effective amendment No. 1 (this “Post-Effective Amendment”) to amend the registration statement on Form S-8 (File No. 333-283728) of the Company (the “Registration Statement”), previously filed with the Securities and Exchange Commission (the “Commission”) on December 11, 2024, registering 118,000,000 ordinary shares under the 2024 Equity Incentive Plan.

On October 13, 2025, the Company effected a forty (40)-for-one (1) share consolidation (the “Share Consolidation”), an adoption of dual-class share structure consisting of 235,000,000 Class A ordinary shares, par value US$0.0002 per share and 15,000,000 Class B ordinary shares, par value US$0.0002 per share (the “Dual-Class Share Structure”), and an amendment and restatement of the existing Amended and Restated Memorandum and Articles of Association of the Company by the deletion in their entirety and the substitution in their place of the Amended and Restated Memorandum and Articles of Association of the Company (the “Amended and Restated M&AA”) which incorporate amendments including but not limited to the Share Consolidation and the adoption of the Dual-Class Share Structure and are filed herewith as Exhibit 4.2.

In addition, the Company has resolved to adopt an Amended and Restated 2024 Share Incentive Plan (the “Amended and Restated 2024 Share Incentive Plan”) to reflect the Share Consolidation and Dual-Class Share Structure, which is filed herewith as Exhibit 10.1, replacing the original 2024 Share Incentive Plan filed as Exhibit 10.1 to the Registration Statement. No changes have been made to the Registration Statement other than this explanatory note and the exhibit index of the Registration Statement. Accordingly, this Post-Effective Amendment No. 1 consists only of the cover page, this explanatory note and the amended exhibit index of the Registration Statement.
