China's Ministry of Finance, the China Securities Regulatory Commission and the Hong Kong Accounting and Financial Reporting Council have published a supplementary list of two mainland accounting firms for H-share company audit work. The addition follows the exit of two firms that no longer met the basic review and recommendation requirements, and extends a mechanism under which mainland firms can conduct H-share audits in their own name, helping to reduce Hong Kong listing transaction costs for mainland issuers. The replenishment exercise was launched under a joint notice issued on 19 November 2025. Four firms applied by the 10 December 2025 deadline. A review and recommendation committee and joint working group carried out document checks, disclosed application materials for public supervision on 29 December 2025, conducted on-site inspections covering governance, internal management, quality management and international business, and then scored and ranked the applicants. Rongcheng and Tianzhi International were selected for supplementary recommendation, with the final list confirmed by the Hong Kong Financial Services and the Treasury Bureau and the Hong Kong Accounting and Financial Reporting Council before publication. The authorities said inclusion on the list is not permanent. They will operate dynamic list management and market exit arrangements, reassess H-share audit firms through securities service filing and practice quality inspections, include H-share audit engagements in annual sampling inspections by finance departments at provincial level and above, require firms from the 2025 reporting cycle to submit H-share audit information and audit reports through the unified certified public accountant industry supervisory platform, and continue supervisory information sharing with Hong Kong.
