Hong Kong, Shanghai & Florham Park, NJ — Monday, August 1, 2022: HUTCHMED (China) Limited (“HUTCHMED”, the “Company” or “we”) (Nasdaq/AIM:HCM; HKEX:13), the innovative, commercial-stage biopharmaceutical company, today reports its unaudited financial results and provides updates on key clinical and commercial developments for the six months ended June 30, 2022.

All amounts are expressed in U.S. dollars unless otherwise stated.

2022 INTERIM Results & Business Updates

“HUTCHMED has continued to make good progress in the last six months,” said Mr Simon To, Chairman of HUTCHMED.

“We have driven revenue growth in our innovative portfolio of marketed drugs. With ELUNATE^® for CRC³ and following last year’s successful launches of ORPATHYS^® for MET-driven NSCLC and SULANDA^® for epNETs⁴ and pNETs⁵, this will be the first full year of product sales from three novel, in-house discovered oncology products in China, with strong sales momentum. We have also significantly expanded our in-house commercial team to drive growth. On top of this, in June we announced that TAZVERIK^® was approved for use in the Hainan Pilot Zone, bringing the clinical benefits of a fourth product to patients in China.”

“Our experienced clinical team has also made progress in the first half of this year. We have initiated a number of key early-stage trials and our later-stage pipeline of on-going studies are also moving at a steady pace, with promising new data from the SAVANNAH study of savolitinib combined with osimertinib being presented in more detail in August. We believe that the achievement of these milestones demonstrates the depth and potential of our R&D⁶ pipeline, which is the core of our business and the foundation for our growth in the years ahead.”

“HUTCHMED continues to be well-financed, which positions us well to continue delivering on our strategic objectives. We are a global biopharmaceutical company developing high quality, novel oncology and immunology drug candidates for patients across the world and under the leadership of Dr Weiguo Su, our new Chief Executive Officer, I have great hope for the future.”

Dr Weiguo Su said, “In HUTCHMED, I see a company with exciting science and a first-in-class or differentiated, best-in-class pipeline of clinical-stage candidates, each with substantial prospects for additional indications and combinations, which is exceptional, particularly in the China biopharma industry.”

“After driving our innovation as Head of Research and Chief Scientific Officer for the last 16 years, I was delighted to become the Chief Executive Officer earlier this year and am very excited about the next chapter of our growth.”

“There are several reasons which underline the opportunity in our future. These include our expected ongoing growth of ORPATHYS^®, SULANDA^® and ELUNATE^® revenues in China, and FRESCO-2, our first global, multi-regional clinical trial, which is due to read out later this month. While receiving a Complete Response Letter for surufatinib from the U.S. FDA⁷ earlier this year and our decision today to withdraw the EMA⁸ MAA⁹ are a disappointment, it has no impact on our global development strategy. We will continue to leverage our solid balance sheet, strong commercial capability with extensive China coverage that generates cash, pipeline of innovative products and world-class people, as we work towards our goal of being a leading global biopharmaceutical company.”

I. COMMERCIAL OPERATIONS

VI. IMPACT OF COVID-19

COVID-19 had some impact on our research, clinical studies and our commercial activities in the first half of 2022, particularly with respect to hospital lockdowns, travel restrictions, and shipping difficulties. Sites in Shanghai were particularly impacted during April and May. Measures were put in place to minimize the impact of such restrictions to the extent possible, including online patient follow-up and the retention of core research teams on-site to maintain critical activities, with business returning to normal in June. We will continue to closely monitor the evolving situation.

VII. SUSTAINABILITY

The Group is committed to the long-term sustainability of its businesses and the communities in which we conduct business. In the first half of 2022, we published 2021 Sustainability Report of HUTCHMED, detailing our environmental, social and governance performance of HUTCHMED during 2021, including our sustainability governance, stakeholder engagement and materiality analysis, business ethics, environmental performance, research and development, responsible commercialization, and human capital management.

Five new sustainability-related policies and statements – Sustainability Policy, Environmental Policy, Health and Safety Policy, Human Rights Policy and Modern Slavery and Human Trafficking Statement – were published along with the 2021 Sustainability Report, serving to demonstrate our commitment in sustainability, enriched and more transparent disclosures, as well as acting as an important gateway to communicate with our stakeholders in all sustainability matters.

In the second half of 2022, we will continue our efforts in facilitating discussions regarding relevant sustainability issues and opportunities, including climate-related issues, and actively looking to set our own sustainability targets and goals.

VIII. U.S. LISTING

The Holding Foreign Companies Accountable Act, or the Act, was signed into law in December 2020.  It provides that if the U.S. Securities and Exchange Commission (SEC) determines that a U.S.-listed company has filed audit reports issued by a registered public accounting firm that has not been subject to inspection by the Public Company Accounting Oversight Board (PCAOB) for three consecutive years beginning in 2021, the SEC shall prohibit such company’s shares or ADSs⁴⁰ from being traded on a national securities exchange or in the over-the-counter trading market in the U.S.

As had been expected, following its adoption of implementing rules pursuant to the Act, the SEC named over 150 companies, including HUTCHMED, to its conclusive list of issuers identified under these rules. Under the current terms of the Act, the Company’s ADSs will be delisted from the Nasdaq Stock Market in early 2024, unless the Act is amended to exclude the Company or the PCAOB is able to conduct a full inspection of the Company’s auditor during the required timeframe. In addition, legislation is being considered in the U.S. to shorten the number of non-inspection years from three years to two. In the case that such legislation becomes law, it will reduce the time period before our ADSs could be delisted from the Nasdaq Stock Market and prohibited from over-the-counter trading in the U.S. from 2024 to 2023.

This has had no impact on the Company’s business operations. We continue to monitor market developments and evaluate all strategic options, with the appropriate counsel and guidance.

The Company’s ADSs, each of which represents five ordinary shares, continue to trade uninterrupted on the Nasdaq Global Select Market. Its ordinary shares are also admitted for trading in London on the AIM market, and are primary listed on HKEX⁴¹. The shares listed on HKEX and AIM are fully fungible with the shares represented by the Company’s ADSs.

INTERIM 2022 Financial Results

Cash, Cash Equivalents and Short-Term Investments were $826.2 million as of June 30, 2022 compared to $1,011.7 million as of December 31, 2021.

• Adjusted Group (non-GAAP⁴²) net cash flows excluding financing activities in the first half of 2022 were -$110.9 million (H1-21: -$63.1m) mainly due to increased spending on Oncology/Immunology R&D and China commercial operations; and
• Net cash used in financing activities in the first half of 2022 totaled $74.6 million (H1-21: net cash generated from financing activities of $578.3m) mainly due to the repayments of bank borrowings and purchases of ADSs by a trustee for the settlement of equity awards.

Revenues for the six months ended June 30, 2022 were $202.0 million compared to $157.4 million in the six months ended June 30, 2021.

• Oncology/Immunology consolidated revenues increased 113% (111% at CER) to $91.1 million (H1-21: $42.9m) resulting from:

ELUNATE^® revenues increased 21% to $36.0 million (H1-21: $29.8m) in manufacturing revenues, promotion and marketing service revenues and royalties, as our in-house sales team increased in-market sales 26% to $50.4 million (H1-21: $40.1m), as provided by Lilly;

SULANDA^® revenues increased 69% to $13.6 million (H1-21: $8.0m), after inclusion on the NRDL starting in January 2022;

ORPATHYS^® revenues of $13.8 million (H1-21: nil), in manufacturing revenues and royalties. AstraZeneca reported $23.3 million in-market sales (H1-21: nil) of ORPATHYS^® in first half of 2022;

TAZVERIK^® revenues of $0.1 million following its successful launch in Hainan in June 2022;

Milestone payment of $15.0 million (H1-21: nil), to us by AstraZeneca, was triggered in February 2022 upon initiation of start-up activities for SAFFRON; and

Other R&D services income of $12.6 million (H1-21: $5.1m), which were primarily fees from AstraZeneca and Lilly for the management of development activities in China.

• Other Ventures consolidated revenues decreased 3% (-4% at CER) to $110.9 million (H1-21: $114.5m), mainly due to lower sales of consumer products. This excludes the strong 18% (16% at CER) growth in non-consolidated revenues at SHPL of $212.4 million (H1-21: $180.4m).

Net Expenses for the six months ended June 30, 2022 were $364.9 million compared to $259.8 million in the six months ended June 30, 2021.

• Cost of Revenues were $137.3 million (H1-21: $123.2m), the majority of which were the cost of third-party prescription drug products marketed through our profitable Other Ventures, as well as costs associated with ELUNATE^®, including the provision of promotion and marketing services to Lilly, and the costs for SULANDA^® and ORPATHYS^® which commenced commercial sales in July 2021;
• R&D Expenses were $181.7 million (H1-21: $123.1m), which increased mainly as a result of an expansion in the active development of our novel oncology drug candidates. Our international clinical and regulatory operations in the U.S. and Europe incurred expenses of $83.6 million (H1-21: $59.3m), while R&D expenses in China were $98.1 million (H1-21: $63.8m);
• SG&A Expenses⁴³ were $79.8 million (H1-21: $54.8m), which increased primarily due to higher staff costs and selling expenses to support rapidly expanding operations. This included the scaling of a national oncology commercial infrastructure in China and in the U.S.; and
• Other Items generated net income of $33.9 million (H1-21: $41.3m), which decreased primarily due to a reduction in equity in earnings of equity investees of $9.4 million after the divestiture of our interest in HBYS in September 2021.

Net Loss attributable to HUTCHMED for the six months ended June 30, 2022 was $162.9 million compared to $102.4 million in the six months ended June 30, 2021.

• As a result, the net loss attributable to HUTCHMED in the first half of 2022 was $0.19 per ordinary share / $0.96 per ADS, compared to net loss attributable to HUTCHMED of $0.14 per ordinary share / $0.70 per ADS in the six months ended June 30, 2021.
