Waterdrop Inc. Announces Third Quarter 2025 Unaudited Financial Results

BEIJING, December 3, 2025 - Waterdrop Inc. ("Waterdrop", the "Company" or "we") (NYSE: WDH), a leading technology platform dedicated to insurance and healthcare service with a positive social impact, today announced its unaudited financial results for the three and nine months ended September 30, 2025.

Financial and Operational Highlights for the Third Quarter of 2025

Mr. Peng Shen, Founder, Chairman, and Chief Executive Officer of Waterdrop, commented, "We are pleased to announce another quarter of outstanding performance, marked by robust revenue expansion and significant profit growth.

For our insurance business, we upgraded our data infrastructure and real-time identification capabilities, allowing us to gain profound insights of our users within milliseconds. This enables us to optimize traffic utilization and sharpen user-acquisition performance, fueling a 32.3% sequential increase in insurance premiums. Moreover, we prioritize user needs and continue to deliver innovative insurance products to users and their loved ones. In this quarter, we introduced 'Quan Jia Fu Family Protection Plan', which covers up to nine family members under a single policy, and upgraded 'Guo Min Bao Mid-to-High-End Medical Insurance' with an expanded network of quality private hospitals.

Our commitment to AI is creating a faster, more efficient, and more intelligent platform. By deploying AI at key touchpoints, we are unlocking new levels of performance. Premiums facilitated by our 'AI Medical Insurance Expert' increased by 82% on a quarter-over-quarter basis. Thanks to our 'KEYI.AI' underwriting assistant, underwriting workflow is streamlined and the corresponding processing time is dramatically reduced, turning tasks that previously took several minutes into a near-instantaneous process. Meanwhile, our 'AI Customer Service Agent' can now independently handle approximately 600,000 inquiries in one month. To democratize these capabilities, we have launched 'Waterdrop Sea.AI', a low-code platform that empowers our employees to build and deploy custom AI solutions, further accelerating innovation across the organization.

During the third quarter, Waterdrop Medical Crowdfunding markedly fortified its campaign risk control measures. By analyzing donation visit data to identify subtle patterns, advanced analytics have improved the identification capabilities of our algorithm model. This, in turn, has improved automatic early-warning systems to better detect and reduce fraud. This quarter also witnessed the rollout of a strengthened donor evaluation system, which now offers comprehensive evaluation rationales and gives donors clear insights into how their contributions are allocated and used. These measures have profoundly enhanced the transparency, rationality, and traceability of fund distribution.

During this quarter, the E-Find Platform has consistently delivered satisfactory fulfillment quality by collaborating across our ecosystem channels and enhancing digital capabilities. At the same time, the number of ongoing projects has increased steadily. In the third quarter, we expanded our collaboration network by partnering with 216 pharmaceutical and contract research organizations. Furthermore, the number of patients enrolled reached 1,066, fueling a 31.3% year-over-year increase in revenue.

We deeply value the trust of our investors and are dedicated to delivering strong returns for shareholders. By the end of November 2025, the company had cumulatively repurchased around 58.1 million ADSs from the open market. We also recently completed our latest cash dividend of approximately US$10.9 million.

In 2025 and beyond, we expect business momentum to continue. AI is driving more and more pragmatic advancements in our business, shaping future services for better experience, improving efficiency, and bringing tangible value to users and our shareholders." Net operating revenue for the third quarter of 2025 increased by 38.4% year-over-year to RMB974.9 million (US$136.9 million) from RMB704.1 million for the same period of 2024.

Supplemental Information

We organize and report our business in the following operating segments:

The table below sets forth the segment operating results, with three-month and nine-month ended September 30, 2024 retrospectively adjusted to conform to this presentation.

Exchange Rate

This announcement contains translations of certain RMB amounts into U.S. dollars ("USD" or "US$") at specified rates solely for the convenience of the reader. Unless otherwise stated, all translations from RMB to USD were made at the rate of RMB7.1190 to US$1.00, the noon buying rate in effect on September 30, 2025 in the H.10 statistical release of the Federal Reserve Board. The Company makes no representation that the RMB or USD amounts referred could be converted into USD or RMB, as the case may be, at any particular rate or at all. For analytical presentation, all percentages are calculated using the numbers presented in the financial statements contained in this earnings release.

Non-GAAP Financial Measure

The Company uses non-GAAP financial measure, adjusted net profit attributable to our ordinary shareholders, in evaluating the Company's operating results and for financial and operational decision-making purposes. Adjusted net profit attributable to our ordinary shareholders represents net profit attributable to our ordinary shareholders excluding share-based compensation expense attributable to our ordinary shareholders, foreign currency exchange gain or losses, impairment of intangible assets acquired from business combination and related tax effects on non-GAAP adjustments.

The non-GAAP financial measure is not presented in accordance with U.S. GAAP and may be different from non-GAAP methods of accounting and reporting used by other companies. The non-GAAP financial measure has limitations as analytical tools and when assessing the Company's operating performance, investors should not consider it in isolation, or as a substitute for net loss or other consolidated statements of comprehensive loss data prepared in accordance with U.S. GAAP. The Company encourages investors and others to review its financial information in its entirety and not rely on a single financial measure. Investors are encouraged to review the Company's historical non-GAAP financial measure to the most directly comparable GAAP measure. Adjusted net profit attributable to our ordinary shareholders presented here may not be comparable to similarly titled measure presented by other companies. Other companies may calculate similarly titled measure differently, limiting its usefulness as a comparative measure to our data.

The Company mitigates these limitations by reconciling the non-GAAP financial measure to the most comparable U.S. GAAP performance measure, all of which should be considered when evaluating the Company's performance.

For more information on the non-GAAP financial measure, please see the table captioned "Reconciliation of GAAP and Non-GAAP Results" set forth at the end of this press release.
