Aesthetic Medical InternationalReports First Half of 2025 Unaudited Financial Results

Shenzhen, China, August 19, 2025 — Aesthetic Medical International Holdings Group Limited (OTCQX: PAIYY) (the “Company” or “AIH”), a leading provider of aesthetic medical services in China, announced its unaudited financial results for the six months ended June 30, 2025.

Mr. Zhang Chen, the Chairman of the Company, commented, “Looking back at the first half of 2025, we are pleased with the positive feedback received on our operational optimization and service quality improvements over the past period. In the first half of this year, our revenue decreased by 3.5% year-on-year, and the total number of treatment cases dropped by 2.3% compared to the same period last year. Despite the overall trend of downgraded market consumption in the first half of 2025, we experienced only a minor decline in performance. We remain confident that, with the continued dedication of all our employees, the Company is well-positioned to gradually improve its performance. To accommodate a higher volume of patient visits, we have implemented the 7S On-Site Management Method, which stands for the initials of seven Japanese and English terms: Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), Shitsuke (Sustain), Service, and Saving. By introducing this management system, we have significantly improved the cleanliness and organization of various functional areas, including public spaces, consultation rooms, doctors’ examination rooms, and treatment rooms. As a result, our customers can experience an orderly and comfortable environment even during peak times. Looking ahead, we plan to further explore innovation and customer service improvements to strengthen our competitive positioning.”

Revenue

Total revenue was RMB350.6 million (USD48.9 million), representing a decrease of 3.5% from RMB363.4 million in the first half of 2024, primarily attributable to reduced advertising expenditures in the first half of 2025.

Cost of sales and services rendered

Cost of sales and services rendered was RMB200.9 million (USD28.0 million), representing a decrease of 1.5% from RMB203.9 million in the first half of 2024, imarily attributable to the reduction of sales and treatment cases.

Gross profit

Gross profit was RMB149.7 million (USD20.9 million), representing a decrease of 6.1% from RMB159.5 million in the first half of 2024. Gross profit margin was 42.7%, down 4.8 percentage points from 47.5% in the first half of 2024. The decrease in gross profit margin was primarily due to a higher proportion of non-surgical aesthetic treatments, which typically generate lower average spending per customer and incur higher medical consumable costs.

Selling expenses

Selling expenses were RMB98.3 million (USD13.7 million), accounting for 28.0% of the Company’s total revenue in the first half of 2025, compared with RMB116.9 million, or 32.2% of total revenue, in the first half of 2024. The year-on-year decrease of 4.2 percentage points was mainly a result of the Company's strategic reduction in online advertising budgets.

General and administrative expenses

General and administrative expenses were RMB47.3 million (USD6.6 million), representing a decrease of 21.4% from RMB60.2 million in the first half of 2024, primarily due to the optimization of the Company’s organizational structure and management efficiency.

Other gains/(losses), net

Other gains/(losses), net amounted to a loss of RMB8.6 million (USD1.2 million), compared with a loss of RMB2.2 million in the first half of 2024. The increase in net loss was primarily due to the deregistration of a subsidiary and the disposal of property.

Loss for the period

As a result of the foregoing, the Company recorded a net loss of RMB9.8 million (USD1.4 million) for the first half of 2025, compared with a net loss of RMB22.4 million in the first half of 2024. Basic and diluted loss per share were both RMB0.06 (USD0.01) for the first half of 2025, compared with RMB0.15 for both basic and diluted loss per share in the first half of 2024.

Certain Non-IFRS items^5^

EBITDA for the first half of 2025 was RMB26.4 million (USD3.7 million), compared with RMB13.9 million for the first half of 2024.

Adjusted EBITDA for the first half of 2025 was RMB35.3 million (USD4.9 million), compared with RMB16.0 million for the first half of 2024.

Adjusted loss after tax for the first half of 2025 was RMB0.9 million (USD0.1 million), compared with a loss of RMB20.3 million for the first half of 2024.

^5^ EBITDA, adjusted EBITDA, and adjustedprofit/(loss) are not prepared in accordance with International Financial Reporting Standards as issued by the International AccountingStandard Board, or IFRS. For more information regarding non-IFRS financials, please refer to “Non-IFRS Financial Measures”and “Reconciliations of IFRS and Non-IFRS Results” included elsewhere in this report.

Cash and cash equivalents

Cash and cash equivalents amounted to RMB23.4 million (USD3.3 million) as of June 30, 2025, compared with RMB44.5 million as of June 30, 2024. The decrease in cash and cash equivalents was primarily attributable to the repayment of bank borrowings, which is reflected under “Borrowings” on our Consolidated Balance Sheet.

Liquidity and capital resources

The Company had a net current liability of RMB300.3 million (USD41.9 million) as of June 30, 2025, which included current borrowings of RMB75.9 million.

Exchange Rate

Solely for the convenience of the reader, this report contains translations of certain Renminbi (RMB) amounts into U.S. dollars (USD). Unless otherwise specified, all translations from RMB to USD are made at the exchange rate of RMB7.1721 to USD1.0, the noon buying rate published by the Federal Reserve Bank of New York on June 27, 2025. Such translations should not be construed as representations that RMB amounts could be converted into USD at that rate or any other rate.

Non-IFRS Financial Measures

EBITDA represents profit before income tax, adjusted to exclude finance costs and amortization and depreciation. Adjusted EBITDA represents EBITDA, adjusted to exclude professional fee, loss on disposal of subsidiaries, and government grant.

Adjusted profit/(loss) represents profit/(loss) for the period, adjusted to exclude professional fee, loss on disposal of subsidiaries, and government grant. We believe these items are not indicative of our core operating performance because they are either non-recurring in nature or not directly related to our business operations.

EBITDA, adjusted EBITDA and adjusted profit/(loss) are non-IFRS financial measures. These non-IFRS measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with IFRS. Furthermore, because non-IFRS measures are not determined in accordance with IFRS, they are susceptible to varying calculations and may not be comparable to other similarly titled measures presented by other companies. You are encouraged to review the Company’s financial information in its entirety and not rely on a single financial measure. A reconciliation of EBITDA, adjusted EBITDA and adjusted profit/(loss) to the most directly comparable IFRS measures is included in the section titled “RECONCILIATIONS OF IFRS AND NON-IFRS RESULTS” below.

The Company presents EBITDA, adjusted EBITDA and adjusted profit/(loss) as supplemental performance measures because it believes that such measures provide useful information to the investors in understanding and evaluating the Company’s results of operations, and facilitate operating performance comparisons from period to period and company to company.
