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(R) for CRC3 and following last year's successful launches of ORPATHYS(R) for MET-driven NSCLC and SULANDA(R) 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(R) 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(R), SULANDA(R) and ELUNATE(R) 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 adisappointment, 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."

V. OTHER VENTURES

Other Ventures include our profitable prescription drug marketing and distribution platforms

-- Other Ventures consolidated revenues fell 3% (-4% at CER(37) ) to $110.9 million (H1-21: $114.5m);

-- SHPL(38) non-consolidated joint venture revenues grew by 18% (16% at CER) to $212.4 million (H1-21: $180.4m); and

-- Consolidated net income attributable to HUTCHMED from our Other Ventures increased by 19% (16% at CER) to $35.4 million (H1-21: $29.8m, excluding net income attributable to HUTCHMED of $11.5 million contributed from HBYS(39) which was disposed in September 2021), which primarily included net income contributed from SHPL of $33.6 million (H1-21: $28.6m).

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-GAAP(42) ) 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(R) 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(R) revenues increased 69% to $13.6 million (H1-21: $8.0m), after inclusion on the NRDL starting in January 2022;

ORPATHYS(R) 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(R) in first half of 2022;

TAZVERIK(R) 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(R) , including the provision of promotion and marketing services to Lilly, and the costs for SULANDA(R) and ORPATHYS(R) 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 Expenses(43) 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.

OPERATIONS REVIEW

Oncology/Immunology

We discover, develop, manufacture and market targeted therapies and immunotherapies for the treatment of cancer and immunological diseases through a fully integrated team of approximately 960 scientists and staff (December 31, 2021: 820), and an in-house oncology commercial organization of about 820 staff (December 31, 2021: 630).

We have advanced 13 oncology drug candidates into clinical trials in China, with seven also in clinical development in the U.S. and Europe. Our first three drug candidates, fruquintinib, surufatinib and savolitinib, have all been approved and launched in China and a fourth, tazemetostat, has been approved and launched in Hainan Pilot Zone.

MARKETED PRODUCT SALES

Fruquintinib (ELUNATE(R) in China)

ELUNATE(R) is approved for the treatment of third-line metastatic CRC for which there is an approximate incidence of 83,000 new patients per year in China. We estimate that in the first half of 2022, approximately 14,000 (H1-21: approximately 10,000) new patients were treated with ELUNATE(R) in China resulting in in-market sales of $50.4 million, up 26% versus H1-21 ($40.1 million). ELUNATE(R) surpassed regorafenib in prescription numbers for late stage CRC at the end of 2021 and that lead has continued to grow in the first half of 2022.

Under the terms of our agreement with Lilly, HUTCHMED manages all on-the-ground medical detailing, promotion and local and regional marketing activities for ELUNATE(R) in China. We consolidate as revenues approximately 70-80% of ELUNATE(R) in-market sales from manufacturing fees, service fees and royalties paid to us by Lilly. In the first half of 2022, we consolidated $36.0 million in revenue for ELUNATE(R) , equal to 71.4% of in-market sales.

Following negotiations with the China NHSA(44) , ELUNATE(R) continues to be included in the NRDL for a new two-year term starting in January 2022. For this renewal, we agreed to a discount of 5% relative to the 2021 NRDL price.

In January 2022, ELUNATE(R) was approved in the Macau Special Administrative Region, our first drug to be approved in the territory and the first based on NMPA approval, following the latest update to the Macau provisions on new drug importation which allow drugs approved in one or more specified jurisdictions to be authorized for use in Macau.

Surufatinib (SULANDA(R) in China)

SULANDA(R) was launched in China in 2021 for the treatment of all advanced NETs(45) for which there is an approximate incidence of 34,000 new patients per year in China.

In 2021, SULANDA(R) was sold as a self-pay drug. We used means-tested early access and patient access programs to help patients afford SULANDA(R) . Despite these access programs, duration of treatment was often affected by the economic constraints of patients. Following negotiations with the China NHSA, SULANDA(R) was included in the NRDL starting in January 2022 at a 52% discount on our main 50mg dosage form, relative to the 2021 self-pay price. Under the NRDL, actual out-of-pocket costs for patients in the first half of 2022 represented approximately 15-20% of the 2021 self-pay price.

As a result of inclusion in the NRDL and our continued marketing activities, patient access to SULANDA(R) , as well as duration of treatment, have been expanding with total sales in the first half of 2022 increasing by 69% to $13.6 million (H1-21: $8.0 million). It should be noted that the first half of 2021 in-market sales included normal pipeline fill behind the initial launch of SULANDA(R) whereas 2022 figures represent consumption sales. In the first half of 2022, approximately 7,500 new patients were treated with SULANDA(R) , representing approximately 3.8 times the approximately 2,000 new patients in the first half of 2021. In June 2022, approximately 1,300 continuing patients were also treated.

There are two therapies for advanced NETs approved and NRDL reimbursed in China: SUTENT(R) for the treatment of pancreatic NET (approximately 10% of NET), and AFINITOR(R) in broadly the same indication as SULANDA(R) .

In April 2022, SULANDA(R) was approved in the Macau Special Administrative Region.

Savolitinib (ORPATHYS(R) in China)

In late June 2021, ORPATHYS(R) became the first-in-class selective MET inhibitor to be approved in China. Our partner, AstraZeneca, then launched ORPATHYS(R) in mid-July 2021, less than three weeks after its conditional approval by the NMPA for patients with MET exon 14 skipping alteration NSCLC.

More than a third of the world's lung cancer patients are in China and, among those with NSCLC, approximately 2-3% have tumors with MET exon 14 skipping alterations, representing an approximate incidence of 13,000 new patients per year in China. Importantly also, MET plays a role in multiple other solid tumors, with an estimated total incidence of 120,000 new patients per year in China.

AstraZeneca introduced a patient access program in late 2021 which subsidizes use of ORPATHYS(R), through progressive disease. As a result, in-market sales for ORPATHYS(R) grew significantly in the first half of 2022. In-market sales of ORPATHYS(R) were $23.3 million (H1-21: nil) resulting in our consolidation of $13.8 million (H1-21: nil) in revenues from manufacturing fees and royalties in the first half of 2022.

Market understanding of the need for MET testing has improved significantly, with ORPATHYS(R)'s brand share more than doubling since the end of 2021 in the rapidly growing targeted therapy area. In the National Health Commission's Treatment Guidelines for Primary Lung Cancer 2022 and the China Medical Association Oncology Committee Lung Cancer Group's China Medical Association Guideline for Clinical Diagnosis and Treatment of Lung Cancer, ORPATHYS(R) was identified as the only targeted therapy recommended for MET exon 14 patients, while similar guideline from CSCO46 also recommended ORPATHYS(R) as the standard of care for such patients.

AstraZeneca and HUTCHMED are preparing to begin negotiations with the China NMPA for potential inclusion in the 2023 NRDL.

ORPATHYS(R) is the first and only selective MET inhibitor on the market in China. XALKORI(R) is an approved multi-kinase inhibitor of ALK and ROS1 with modest MET activity. Several selective MET inhibitors are in development in China, but none are currently expected to reach the market before 2023.

RESEARCH & DEVELOPMENT

Savolitinib (ORPATHYS(R) in China)

Savolitinib is an oral, potent, and highly selective oral inhibitor of MET. In global partnership with AstraZeneca, savolitinib has been studied in NSCLC, PRCC(47) and gastric cancer clinical trials with over 1,500 patients to date, both as a monotherapy and in combinations.

In February 2022, a $15 million milestone payment from AstraZeneca was triggered by the initiation of start-up activities for the SAFFRON study. In total, AstraZeneca has paid HUTCHMED $85 million of the total $140 million in upfront payments, development and approvals milestones that are potentially payable under the 2011 license and collaboration agreement.

Savolitinib - Lung cancer:

MET plays an important role in NSCLC . Savolitinib has made significant development progress in lung cancer, completing NMPA NDA review, gaining approval and successfully launching as a monotherapy in China. It is also now in multiple late stage registrational studies as a combination therapy.

The table below shows a summary of the clinical studies for savolitinib in lung cancer patients.

Update on MET altered, EGFR wild type NSCLC in China - The June 2021 monotherapy approval by the NMPA was based on positive results from a Phase II trial conducted in China in patients with NSCLC with MET exon 14 skipping alterations (NCT02897479). Final OS and subgroup analysis was presented for this trial at ELCC 2022. The updated results further confirmed the favorable benefit of savolitinib in these patients and in each subgroup and the acceptable safety profile. In addition to this trial and the confirmatory study in this patient population (NCT04923945), the SOUND Phase II trial is an open-label, interventional, multicenter, exploratory Phase II study to evaluate savolitinib combined with IMFINZI(R) in EGFR/ALK/ROS1 wild-type, locally advanced or metastatic NSCLC patients with MET aberrations (NCT05374603). The primary endpoint is PFS.

Update on combination therapies in EGFR TKI-resistant NSCLC - MET-aberration is a major mechanism for acquired resistance to both first/second-generation EGFR TKIs as well as third-generation EGFR TKIs like TAGRISSO(R). Among patients who experience disease progression post-TAGRISSO(R) treatment, approximately 15-50% present with MET aberration. The prevalence of MET amplification and overexpression may differ depending on the sample type, detection method and assay cut-off used. Savolitinib has been studied extensively in these patients in the TATTON and SAVANNAH studies. The encouraging results led to the initiation and planning of three Phase III studies: SACHI and SANOVO were initiated in China in 2021, and the global, pivotal Phase III SAFFRON study is currently open for enrollment.

SAVANNAH (NCT03778229) - This global Phase II study in patients who have progressed following TAGRISSO(R) due to MET amplification or overexpression has three dose cohorts of savolitinib combined with TAGRISSO(R). In addition to continuing TAGRISSO(R) treatment, patients received savolitinib 300mg QD, 300mg BID, or 600mg QD. 294 patients are enrolled in the study. We continue to evaluate the possibility of using the SAVANNAH study as the basis for U.S. accelerated approval.

The first presentation of results will be at the upcoming 2022 WCLC. These results are based on an analysis of 193 efficacy evaluable patients who received savolitinib 300mg once daily plus TAGRISSO(R) 80mg once daily at data cut-off date of August 27, 2021. Qualifying MET aberrations are FISH5+50 or IHC50+51. Importantly, additional analysis using a higher cut-off level of MET aberration are presented. The higher cut-off levels for MET aberration are FISH10+52 and/or IHC90+53. The prevalence of this higher cut-off levels of MET aberration was 34% of patients centrally tested for enrollment in this study vs. 62% at the lower, qualifying cut-off level.

Results showed a trend toward improved response rates with increasing level of MET aberration. Across all patients in this analysis, ORR54 was 32% [95% CI: 26-39%], median DoR was 8.3 months [95% CI: 6.9-9.7 months], and median PFS was 5.3 months [95% CI: 4.2-5.8 months]. These results are consistent with the TATTON and ORCHARD global studies.

Among the 108 SAVANNAH patients who met the criteria for higher cut-off levels of MET aberration, ORR was 49% [95% CI: 39-59%], median DoR was 9.3 months [95% CI: 7.6-10.6 months], and median PFS was 7.1 months [95% CI: 5.3-8.0 months]. Among the 87 patients who did not receive prior chemotherapy, ORR was 52% [95% CI: 41-63%], median DoR was 9.6 months [95% CI: 7.6-14.9 months], and median PFS was 7.2 months [95% CI: 4.7-9.2 months]. The safety profile of savolitinib plus TAGRISSO(R) was consistent with the known profiles of the combination and each treatment alone.

SAFFRON (NCT05261399) - Findings based on SAVANNAH and the TATTON study supported the initiation of the SAFFRON global Phase III study in patients with EGFR-mutated, MET-driven, locally advanced or metastatic NSCLC whose disease progressed on first- or second-line treatment with TAGRISSO(R) as the most recent therapy, with no prior chemotherapy in the metastatic setting allowed. Patients will be prospectively selected for the higher level of MET aberration of FISH10+ and/or IHC90+. The SAFFRON study will evaluate the efficacy and safety of savolitinib in combination with TAGRISSO(R) compared to pemetrexed plus platinum doublet-chemotherapy, the current standard-of-care treatment in this setting. The primary endpoint of the study is PFS.

Two registrational studies are ongoing in China in EGFR mutated NSCLC with MET aberrations: the SANOVO (NCT05009836) study in treatment naïve patients, and SACHI (NCT05015608) study in patients whose disease progressed following treatment with any first-line EGFR TKI.

Savolitinib - Kidney cancer:

MET is a key genetic driver in papillary RCC(55) , and emerging evidence suggests that combining immunotherapies with a MET inhibitor could enhance anti-tumor activity. PRCC is a subtype of kidney cancer, representing about 15% of patients, with no treatments approved for patients with tumors that harbor MET-driven alterations. We have conducted multiple global studies of savolitinib in PRCC patients, including the SAVOIR monotherapy and CALYPSO combination therapy global Phase II trials, that both demonstrated highly encouraging results. These results led to the initiation of a global Phase III, the SAMETA study, in 2021.

The table below shows a summary of the clinical study for savolitinib in kidney cancer patients.

Savolitinib - Gastric cancer:

MET-driven gastric cancer has a very poor prognosis . Multiple Phase II studies have been conducted in Asia to study savolitinib in MET-driven gastric cancer, of which approximately 5% of all gastric cancer patients, demonstrated promising efficacy, including VIKTORY. The VIKTORY study reported a 50% ORR with savolitinib monotherapy in gastric cancer patients whose tumors harbor MET amplification.

Fruquintinib (ELUNATE(R) in China)

Fruquintinib is a novel, selective, oral inhibitor of VEGFR 1/2/3 kinases that was designed to improve kinase selectivity to minimize off-target toxicity and thereby improve tolerability. Fruquintinib has been studied in clinical trials with about 5,000 patients to date, both as a monotherapy and in combination with other agents.

Aside from its first approved indication of third-line CRC (in China), several studies of fruquintinib combined with checkpoint inhibitors (including TYVYT(R), geptanolimab and tislelizumab) have been underway, some of which presented encouraging data in 2021. Registration-intent studies combined with chemotherapy (FRUTIGA study in gastric cancer) or checkpoint inhibitors (TYVYT(R) combo, in endometrial cancer) are ongoing in China, with further registration studies in HCC56 and RCC under consideration.

We retain all rights to fruquintinib outside of China and are partnered with Lilly in China. The table below shows a summary of the clinical studies for fruquintinib.

Fruquintinib - CRC updates:

FRESCO-2 (NCT04322539) - This double-blind, placebo-controlled, global Phase III study in patients with refractory metastatic CRC reached its enrollment goal in December 2021. It recruited 691 patients from approximately 150 sites in 14 countries in fifteen months, ahead of schedule. The primary endpoint of the study is OS. Topline results are expected to be reported in August 2022 as the pre-specified number of OS events that trigger the primary analysis has accrued. If positive, HUTCHMED would simultaneously initiate plans to apply for marketing authorization of fruquintinib with the U.S. FDA, which granted Fast Track Designation in 2020, the EMA and the Japanese PMDA.

U.S. Phase I/Ib CRC cohorts (NCT03251378) - Preliminary efficacy and safety data of fruquintinib in patients with refractory, metastatic CRC were presented at ASCO GI in early 2022. In patients who had progressed on all standard therapies, including LONSURF(R) and/or STIVARGA(R) , the DCR(61) was 68.3% and the median OS was 10.7 months [95% CI: 6.7-11.7]. In patients who had not received LONSURF(R) or STIVARGA(R) , the DCR was 57.5% and the median OS was 9.3 months [95% CI: 5.2-NR(62) ]. The safety profile in both patient populations was consistent with what has previously been reported.

Fruquintinib - Gastric cancer:

FRUTIGA (NCT03223376) - This randomized, double-blind, Phase III study in China to evaluate fruquintinib combined with paclitaxel compared with paclitaxel monotherapy, for second-line treatment of advanced gastric cancer, enrolled approximately 700 patients in July 2022. Its co-primary endpoints are PFS and OS.

Fruquintinib - Combinations with checkpoint inhibitors:

Advanced endometrial cancer registration-intent cohort of TYVYT(R) combination (NCT03903705) - Platinum-based systemic chemotherapy is the standard first-line treatment for advanced endometrial cancer. However, patients who progress following first-line chemotherapy have limited treatment options, and the prognosis remains poor. As disclosed at CSCO 2021, data in this endometrial cancer cohort is encouraging.

As of the data cutoff date of August 31, 2021, 35 patients were enrolled, including 7 treatment-naïve and 28 pretreated patients. Of them, 29 were efficacy evaluable, 4 were treatment-naïve and 25 were pretreated. All 4 treatment-naïve patients experienced confirmed tumor response, for ORR of 100% (95% CI: 39.8-100.0), and median PFS was not reached. Among the 25 pretreated patients, the confirmed ORR was 32.0% (95% CI: 14.9-53.5), DCR was 92.0% (95% CI: 74.0-99.0) and the median PFS was 6.9 months (95% CI: 4.1-NR). Among the 19 proficient mismatch repair (pMMR) patients in pretreated cohort, the confirmed ORR was 36.8% (95% CI: 16.3-61.6), DCR was 94.7% (95% CI: 74.0-99.9), median PFS was 6.9 months (95% CI: 4.1-NR), and the median OS was not reached.

We have agreed with the NMPA to expand this cohort into a single-arm registrational Phase II study. The cohort is now targeting to enroll over 130 patients.

We are currently evaluating the merits of and planning further registration studies based on other cohorts, such as HCC and RCC.

Tislelizumab combinations (NCT04577963 & NCT04716634) - In August 2021, we initiated an open-label, multi-center, non-randomized Phase Ib/II study in the U.S. to assess fruquintinib in combination with tislelizumab in patients with locally advanced triple negative breast cancer, advanced endometrial cancer or MSS-CRC. The safety lead-in phase of the U.S. study has been completed, to be followed by the dose-expansion phase shortly. The Phase II study in China and Korea for fruquintinib in combination with tislelizumab is being led by BeiGene for the treatment of advanced or metastatic, unresectable gastric cancer, CRC or NSCLC.

Fruquintinib - Exploratory development:

We are conducting multiple Phase Ib expansion cohorts in the U.S. to explore fruquintinib in CRC and breast cancer. In China, we support an investigator initiated trial program for fruquintinib, and there are about 40 of such trials ongoing in various solid tumor settings.

Surufatinib (SULANDA(R) in China)

Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with VEGFR and FGFR, both shown to be involved in tumor angiogenesis, and CSF-1R, which plays a key role in regulating tumor-associated macrophages, promoting the body's immune response against tumor cells. Surufatinib has been studied in clinical trials with around 1,200 patients to date, both as a monotherapy and in combinations, and is approved in China. HUTCHMED currently retain all rights to surufatinib worldwide.

Initial approvals for surufatinib in China are for the treatment of advanced NET patients. NETs present in the body's organ system with fragmented epidemiology. About 58% of NETs originate in the gastrointestinal tract and pancreas, 27% in the lung or bronchus, and a further 15% in other organs or unknown origins.

Surufatinib's ability to inhibit angiogenesis, block the accumulation of tumor associated macrophages and promote infiltration of effector T cells into tumors could help improve the anti-tumor activity of PD-1 antibodies. Several combination studies with PD-1 antibodies have shown promising data.

A summary of the clinical studies of surufatinib is shown in the table below.

Surufatinib - monotherapy in NET updates:

U.S. NDA and EMA MAA - Surufatinib received FDA Fast Track Designations in April 2020 for the treatment of pNETs and epNETs. Orphan Drug Designation for pNETs was granted in November 2019. In a May 2020 pre-NDA meeting, we reached an agreement with the FDA that the two positive Phase III studies of surufatinib in patients with pNETs and epNETs in China, along with the bridging trial in the U.S. could form the basis to support a U.S. NDA submission. The FDA accepted the filing of the NDA in June 2021. However, in April 2022, we received a Complete Response Letter from the FDA regarding the NDA for surufatinib for the treatment of pNETs and epNETs. FDA determined that the current data package, based on two positive Phase III trials in China and one bridging study in the U.S., does not support an approval in the U.S. at this time.

The FDA evaluated the applicability of the SANET studies data generated in one country to U.S. patients and U.S. medical practice. The Complete Response Letter stated that the FDA will require a multiregional clinical trial (MRCT) that includes subjects more representative of the U.S. patient population and aligned to current U.S. medical practice. In addition, COVID-19 related issues concerning inspection scheduling and access contributed to the FDA action. This action by the FDA is not related to any safety issues with surufatinib.

We also submitted an EMA MAA for surufatinib using the same data package, which was validated and accepted in July 2021. However, on August 1, 2022, HUTCHMED informed the EMA of its decision to withdraw the MAA. This decision was reached following interactions with the EMA which suggested that there is a low probability of a positive opinion on the MAA. The EMA indicated that the SANET studies were not representative of patients and medical practice in Europe. The Company believes that their critiques on aspects of the design and conduct of the trials are unlikely to be resolved by re-analysis of the existing data set. Additionally, pre-approval on-site inspections are required to confirm Good Manufacturing Practice and Good Clinical Practice. Such inspections are currently subject to restrictions due to COVID-containment measures and security requirements for foreign visitors in China.

We will continue to work with regulators to explore the feasibility of conducting a MRCT that would support approval in U.S. and Europe.

Japan Bridging Study to Support Registration for Advanced NET (NCT05077384) - Based on dialogue with the Japanese PMDA, it was agreed that the Japanese NDA would include results from a 34-patient, registration-enabling bridging study in Japan to complement the existing data package. The trial was initiated in September 2021 and results are expected in the first half of 2023. We plan to engage with the PMDA when these results are available.

Surufatinib - combination therapy with checkpoint inhibitors:

A Phase II China study (NCT04169672) combining surufatinib with TUOYI(R) is enrolling approximately 260 patients in nine solid tumor indications, including NENs, biliary tract cancer, gastric cancer, thyroid cancer, SCLC, soft tissue sarcoma, endometrial cancer, esophageal cancer and NSCLC. These have led to the initiation in September 2021 of the first Phase III trial combining surufatinib with a PD-1 antibody, the SURTORI-01 study in NEC, and we are currently considering further registration studies.

In March 2021 we initiated an open-label, Phase Ib/II study of surufatinib in combination with BeiGene's tislelizumab. This study is ongoing in the U.S. and Europe, evaluating the safety, tolerability, pharmacokinetics and efficacy in patients with advanced solid tumors, including CRC, NET, small cell lung cancer, gastric cancer, and soft tissue sarcoma and anaplastic thyroid cancer. The dose finding phase of the study is now complete and the expansion phase is ongoing (NCT04579757).

Surufatinib - exploratory development:

In China, we support an investigator initiated trial program for surufatinib, with about 50 of such trials in various solid tumor settings being conducted for both combination and single agent regimens. These trials explore and answer important medical questions in addition to our own company-sponsored clinical trials.

Hematological Malignancies Candidates

HUTCHMED currently has six investigational drug candidates targeting hematological malig-nan-cies in clinical development. Amdizalisib (targeting PI3K ), sovleplenib (HMPL-523, targeting Syk) and HMPL-760 (targeting BTK) are being studied in several trials against B-cell dominant malignancies. In addition to the three B-cell receptor pathway inhibitors, HUTCHMED is also develop-ing HMPL-306 (targeting IDH1 and IDH2), tazemetostat (a methyl-trans-ferase inhibitor of EZH2) and HMPL-A83 (an anti-CD47 monoclonal antibody).

Amdizalisib (HMPL-689)

Amdizalisib is a novel, highly selective oral inhibitor targeting the isoform PI3K , a key component in the B-cell receptor signaling pathway. Amdizalisib's pharmacokinetic properties have been found to be favorable with good oral absorption, moderate tissue distribution and low clearance in preclinical studies. We also expect that amdizalisib will have low risk of drug accumulation and drug-drug interactions, supporting feasibility of development in combination with other medicines. The first of such activities is in combination with tazemetostat (IND filed in June 2022). In 2021, registration-intent studies for amdizalisib were initiated and Breakthrough Therapy Designation was granted for relapse or refractory follicular lymphoma in China. HUTCHMED currently retains all rights to amdizalisib worldwide. The table below shows a summary of the clinical studies for amdizalisib.

Phase II registration-intent trial (NCT04849351) - In April 2021, we commenced a registration-intent, single-arm, open-label Phase II trial in China in approximately 100 patients with relapsed/refractory follicular lymphoma and approximately 80 patients with relapsed/refractory marginal zone lymphoma, two subtypes of non-Hodgkin's lymphoma. The primary endpoint is ORR. The trial is being conducted in over 35 sites in China and is expected to be fully enrolled around year end for follicular lymphoma cohort and in the first half of 2023 for marginal zone lymphoma cohort.

Sovleplenib (HMPL-523)

Sovleplenib is a novel, selective, oral inhibitor targeting Syk, for the treatment of hematological malignancies and immune diseases. Syk is a component in Fc receptor and B-cell receptor signaling pathway.

In 2021, we initiated a Phase III study in China for primary ITP, for which it has received Breakthrough Therapy Designation, and presented data on both primary ITP and hematological malignancies at ASH69 2021. HUTCHMED currently retains all rights to sovleplenib worldwide. The table below shows a summary of the clinical studies for sovleplenib.

ESLIM-01 (Evaluation of Sovleplenib for immunological diseases-01, NCT05029635) - In October 2021, we initiated a randomized, double-blinded, placebo-controlled Phase III trial in China of sovleplenib in approximately 180 adult patients with primary ITP who have received at least one prior line of standard therapy. ITP is an autoimmune disorder that can lead to increased risk of bleeding. The primary endpoint of the study is the durable response rate. In January 2022, the NMPA granted Breakthrough Therapy Designation for this indication. Enrollment is expected to be completed around the end of 2022.

China Phase II/III in warm AIHA - This is a randomized, double-blind, placebo-controlled Phase II/III study to evaluate the efficacy, safety, tolerability, and pharmacokinetics of sovleplenib in the treatment of warm AIHA. AIHA is the result of destruction of red blood cells due to the production of antibodies against red blood cells which bind to antigens on the red blood cell membrane in autoimmune disorders. If the results of the Phase II stage of the study indicate sufficiently satisfactory efficacy and safety, the Phase III stage will be initiated. The China IND was approved in July 2022.

China Phase II in COVID-19 - Patients hospitalized with COVID-19 may experience severe inflammation, becoming at risk of multiple organ failures, which is the most common cause of death. Syk inhibition has been shown to reduce severe inflammation in severe and critical patients. This study is a multicenter, randomized, double-blind, placebo-controlled phase II study. The target population is adult patients with severe/critical COVID-19 requiring hospitalization and supplemental oxygen. About 80 patients are planned to be randomized to receive sovleplenib or placebo combined with standard therapy. The primary endpoint is all-cause mortality by day 29. The China IND was approved in June 2022.

Tazemetostat

In August 2021, we entered into a strategic collaboration with Epizyme to research, develop, manufacture and commercialize tazemetostat in Greater China, including the mainland, Hong Kong, Macau and Taiwan. Tazemetostat is an inhibitor of EZH2 developed by Epizyme that is approved by the U.S. FDA for the treatment of certain epithelioid sarcoma and follicular lymphoma patients. It received accelerated approval from the FDA based on ORR and DoR in January and June 2020 for epithelioid sarcoma and follicular lymphoma, respectively.70

We are developing and plan to seek approval for tazemetostat in various hematological and solid tumors, including epithelioid sarcoma, follicular lymphoma and potentially other forms of lymphoma in Greater China. We are participating in Epizyme's SYMPHONY-1 (EZH-302) study, leading it in Greater China. The parties also intend to conduct additional global studies jointly. We will generally be responsible for funding all clinical trials of tazemetostat in Greater China, including the portion of global trials conducted there. We are responsible for the research, manufacturing and commercialization of tazemetostat in Greater China.

The table below shows a summary of the clinical studies for tazemetostat.

Hainan Pilot Zone - In May 2022, tazemetostat was approved by the Health Commission and Medical Products Administration of Hainan Province to be used in the Hainan Boao Lecheng International Medical Tourism Pilot Zone (Hainan Pilot Zone), under the Clinically Urgently Needed Imported Drugs scheme, for the treatment of certain patients with epithelioid sarcoma and follicular lymphoma consistent with the label as approved by the FDA. Launched in 2013 and located in China, the Hainan Pilot Zone is a destination for international medical tourism and global hub for scientific innovation, welcoming 83,900 medical tourists in 2020, according to official data.

SYMPHONY-1 (NCT04224493) - This is a global, multicenter, randomized, double-blind, active-controlled, 3-stage, biomarker-enriched, Phase Ib/III study of tazemetostat in combination with R(2) in patients with relapsed or refractory follicular lymphoma after at least one prior line of therapy. Epizyme conducted the Phase Ib portion of the study in 2021, which determined the recommended Phase III dose and also demonstrated potential efficacy in second-line follicular lymphoma. The safety profile of the combination was consistent with the previously reported safety information in the U.S. prescribing information for both tazemetostat and R(2), respectively.

An interim analysis of the Phase Ib portion of the study, based on 44 follicular lymphoma patients as of January 22, 2022, was presented at ASCO 2022. The safety profile of the tazemetostat and R(2) combination was consistent with the prescribing information for both tazemetostat and R(2), respectively. Additionally, there was no clear dose response for treatment-emergent adverse events (TEAEs) or dose modifications. Of 38 evaluable patients, ORR was 95% with 50% complete response rate. Median PFS and DoR were not yet reached.

In the Phase III portion of the trial, approximately 500 patients are randomly assigned to receive the recommended Phase III dose of tazemetostat + R(2) or placebo + R(2). The study will also include a maintenance arm with tazemetostat or placebo following the first year of treatment with tazemetostat + R(2) or placebo + R(2). The first patients were enrolled in May 2022 and we anticipate the first China patient will enroll in the second half of 2022.

China Phase II bridging study in relapsed/refractory follicular lymphoma (NCT05467943) - In July 2022, we initiated a multicenter, open-label, Phase II study to evaluate the efficacy, safety and pharmacokinetics of tazemetostat for the treatment of patients with relapsed/refractory follicular lymphoma intended to support conditional registration in China. The primary objective is to evaluate the efficacy of tazemetostat in patients with EZH2 mutation (Cohort 1). The secondary objectives are to evaluate the efficacy of tazemetostat in patients with EZH2 wild-type (Cohort 2) and to evaluate the safety and the pharmacokinetics of tazemetostat.

China Phase II combination study in relapsed/refractory follicular lymphoma - This is a multicenter, open-label, Phase II study to evaluate the safety, tolerability and preliminary anti-tumor efficacy of tazemetostat in combination with amdizalisib in patients with R/R lymphoma. An IND was submitted in June 2022.

We intend to initiate other combination studies of tazemetostat with other HUTCHMED assets.

HMPL-295

HMPL-295 is a novel ERK inhibitor. ERK is a downstream component of the RAS-RAF-MEK-ERK signaling cascade (MAPK pathway). This is our first of multiple candidates in discovery targeting the MAPK pathway. A China Phase I study was initiated in July 2021. HUTCHMED currently retains all rights to HMPL-295 worldwide.

RAS-MAPK pathway is dysregulated in cancer, in which mutations or non-genetic events hyper-activate the pathway in approximately 50% of cancers. RAS and RAF predict worse clinical prognosis in a wide variety of tumor types, mediate resistance to targeted therapies, and decrease the response to the approved standards of care, namely, targeted therapy and immunotherapy. ERK inhibition has the potential to overcome or avoid the intrinsic or acquired resistance from the inhibition of RAS, RAF and MEK upstream mechanisms.

HMPL-653

HMPL-653 is a novel, highly selective, and potent CSF-1R inhibitor designed to target CSF-1R driven tumors as a monotherapy or in combination with other drugs. We initiated a China Phase I study in January 2022. HUTCHMED currently retains all rights to HMPL-653 worldwide.

CSF-1R is usually expressed on the surface of macrophages and can promote growth and differentiation of macrophages. Studies have shown that blocking the CSF-1R signaling pathway could effectively modulate the tumor microenvironment, relieve tumor immunosuppression, and synergize with other anti-cancer therapies such as immune checkpoint inhibitors to achieve tumor inhibition. It has been demonstrated in several clinical studies that CSF-1R inhibitors could treat tenosynovial giant cell tumors, and treat a variety of malignancies combined with immuno-oncology or other therapeutic agents. Currently no CSF-1R inhibitor has been approved in China.

HMPL-A83

HMPL-A83 is an investigational IgG4-type humanized anti-CD47 monoclonal antibody that exhibits high affinity for CD47. HMPL-A83 blocks CD47 binding to Signal regulatory protein (SIRP) <ALPHA> and disrupts the "do not eat me" signal that cancer cells use to shield themselves from the immune system. HUTCHMED currently retains all rights to HMPL-A83 worldwide.

In preclinical studies, HMPL-A83 demonstrated a high affinity for CD47 antigen on tumor cells and strong phagocytosis induction of multiple tumor cells. HMPL-A83 also demonstrated weak affinity for red blood cells and no induction of hemagglutination, implying low risk of anemia, a potential event of special interest. HMPL-A83 has also demonstrated strong anti-tumor activity in multiple animal models.

Immunology Collaboration with Inmagene

In January 2021, we entered into a strategic partnership with Inmagene, a clinical development stage company with a focus on immunological diseases, to further develop four novel preclinical drug candidates we discovered for the potential treatment of multiple immunological diseases. Under the terms of the agreement, we granted Inmagene exclusive options to such drug candidates solely for the treatment of immunological diseases. Funded by Inmagene, we will work together to move the drug candidates towards IND. If successful, Inmagene will then advance the drug candidates through global clinical development. INDs for the first two compounds were submitted in 2022.

IMG-007 in atopic dermatitis - This is a novel antagonistic monoclonal antibody targeting the OX40 receptor. OX40 is a costimulatory receptor member of the tumor necrosis factor receptor (TNFR) superfamily expressed predominantly on activated T cells. The ligation of OX40 by its ligand OX40L leads to enhanced T cell survival, proliferation, and effector functions. Preclinical research results show that IMG-007 can bind to human OX40 receptor with high affinity, thereby inhibit the binding of OX40 to OX40L, reducing OX40L-dependent downstream signaling and cytokine release by OX40+ T cells. By selectively shutting down OX40+ T cell function, IMG-007 may provide a treatment option for pathological OX40+ T cell-mediated immune diseases, such as atopic dermatitis. Atopic dermatitis is a chronic inflammatory skin condition that is estimated to affect 8-19% of children and 2-5% of adults in U.S., Europe, and East Asia. The Phase I study in healthy volunteers was initiated in July 2022 in Australia.

IMG-004 in immunological diseases - This is a non-covalent, reversible small molecule inhibitor targeting BTK. Designed specifically for inflammatory and autoimmune diseases that usually require long-term treatment, IMG-004 is potent, highly selective and brain permeable. BTK is involved in innate and adaptive immune responses related to certain immune-mediated diseases. Given the central role of BTK in immunity pathways, BTK inhibitors may offer a potential therapeutic approach for the treatment of a wide range of inflammatory and autoimmune diseases. The Phase I study in healthy volunteers IND has been cleared by the U.S. FDA and enrollment is imminent.

OTHER VENTURES

Our Other Ventures include drug marketing and distribution platforms covering about 290 cities and towns in China with around 2,900 mainly manufacturing and commercial personnel. Built over the past 20 years, it primarily focuses on prescription drug and science-based nutrition products through several joint ventures and subsidiary companies.

In the first six months of 2022, our Other Ventures consolidated revenues were $110.9 million (H1-21: $114.5m), with the decrease mainly due to lower sales of consumer products to $5.3 million (H1-22: $11.8m). Consolidated net income attributable to HUTCHMED from our Other Ventures increased by 19% (16% at CER) to $35.4 million (H1-21: $29.8m, excluding net income attributable to HUTCHMED of $11.5 million contributed from HBYS which was disposed in September 2021).

Hutchison Sinopharm(74) : Our prescription drugs commercial services business, which in addition to providing certain commercial services for our own products, provides services to third-party pharmaceutical companies in China, grew sales by 3% (2% at CER) to $99.3 million in the first half of 2022 (H1-21: $96.2m).

In 2021, the Hong Kong International Arbitration Centre made a final award in favor of Hutchison Sinopharm against Luye75 in the amount of RMB253.2 million ($38.0 million), plus costs and interest (the "Award"), in connection with the termination of Hutchison Sinopharm's right to distribute SEROQUEL(R) in China. In June 2022, Luye provided a bank guarantee of up to RMB286.0 million to cover the Award, pending the outcome of an application by Luye to the High Court of Hong Kong to set aside the Award. On July 26, 2022, Luye's application to set aside the Award was dismissed by the High Court with costs awarded in favor of Hutchison Sinopharm and if Luye does not appeal the dismissal, Hutchison Sinopharm will be seeking to enforce the Award by drawing down on the bank guarantee.

SHPL: Our own-brand prescription drugs business, operated through our non-consolidated joint venture SHPL, grew sales by 18% (16% at CER) to $212.4 million (H1-21: $180.4m). This sales growth and favorable product mix led to an increase of 17% (15% at CER) in net income attributable to HUTCHMED to $33.6 million (H1-21: $28.6m).

The SHPL operation is large-scale, with a commercial team of over 2,200 staff managing the medical detailing and marketing of its products not just in hospitals in provincial capitals and medium-sized cities, but also in the majority of county-level hospitals in China. SHPL's Good Manufacturing Practice-certified factory holds 74 drug product manufacturing licenses and is operated by about 530 manufacturing staff.

SXBX76 pill: SHPL's main product is SXBX pill, an oral vasodilator prescription therapy for coronary artery disease. SXBX pill is the third largest botanical prescription drug in this indication in China, with a national market share in January to April 2022 of 21.5% (2021: 19.6%). Sales increased by 19% (17% at CER) to $197.9 million in the first half of 2022 (H1-21: $167.0m).

SXBX pill is protected by a formulation patent that expires in 2029, but also retains certain state protection that extends indefinitely, and is one of less than two dozen proprietary prescription drugs represented on China's National Essential Medicines List (NEML). Inclusion on this list means that all Chinese state-owned health care institutions are required to carry it. SXBX pill is fully reimbursed in all China.

Dividends: Our share of SHPL's profits are passed to the HUTCHMED Group through dividend payments. In the first six months of 2022, dividends of $22.7 million (H1-21: $42.1m) were paid from SHPL to the HUTCHMED Group level with aggregate dividends received by HUTCHMED since inception of over $260 million.

USE OF NON-GAAP FINANCIAL MEASURES AND RECONCILIATION

In addition to financial information prepared in accordance with U.S. GAAP, this announcement also contains certain non-GAAP financial measures based on management's view of performance including:

   --      Adjusted Group net cash flows excluding financing activities 
   --      CER 

Management uses such measures internally for planning and forecasting purposes and to measure the HUTCHMED Group's overall performance. We believe these adjusted financial measures provide useful and meaningful information to us and investors because they enhance investors' understanding of the continuing operating performance of our business and facilitate the comparison of performance between past and future periods. These adjusted financial measures are non-GAAP measures and should be considered in addition to, but not as a substitute for, the information prepared in accordance with U.S. GAAP. Other companies may define these measures in different ways.

Adjusted Group net cash flows excluding financing activities: We exclude deposits in and proceeds from short-term investments for the period, and exclude the net cash generated from financing activities for the period to derive our adjusted Group net cash flows excluding financing activities. We believe the presentation of adjusted Group net cash flows excluding financing activities provides useful and meaningful information about the change in our cash resources excluding those from financing activities which may present significant period-to-period differences.

CER: We remove the effects of currency movements from period-to-period comparisons by retranslating the current period's performance at previous period's foreign currency exchange rates. Because we have significant operations in China, the RMB to U.S. dollar exchange rates used for translation may have a significant effect on our reported results. We believe the presentation at CER provides useful and meaningful information because it facilitates period-to-period comparisons of our results and increases the transparency of our underlying performance.

GROUP CAPITAL RESOURCES

LIQUIDITY AND CAPITAL RESOURCES

To date, we have taken a multi-source approach to fund our operations, including through cash flows generated and dividend payments from our Oncology/Immunology and Other Ventures operations, service and milestone and upfront payments from our collaboration partners, bank borrowings, investments from third parties, proceeds from our listings on various stock exchanges and follow-on offerings.

Our Oncology/Immunology operations have historically not generated significant profits and have operated at a net loss, as creating potential global first-in-class or best-in-class drug candidates requires a significant investment of resources over a prolonged period of time. As such, we incurred net losses of $162.9 million for the six months ended June 30, 2022 and net losses of $102.4 million for the six months ended June 30, 2021.

As of June 30, 2022, we had cash and cash equivalents and short-term investments of $826.2 million and unutilized bank facilities of $177.8 million. As of June 30, 2022, we had $0.4 million in bank borrowings.

Certain of our subsidiaries and joint ventures, including those registered as wholly foreign-owned enterprises in China, are required to set aside at least 10.0% of their after-tax profits to their general reserves until such reserves reach 50.0% of their registered capital. In addition, certain of our joint ventures are required to allocate certain of their after-tax profits as determined in accordance with related regulations and their respective articles of association to the reserve funds, upon approval of the board.

Profit appropriated to the reserve funds for our subsidiaries and joint ventures incorporated in the PRC was nil and approximately $8,000 for the six months ended June 30, 2022 and 2021, respectively. In addition, as a result of PRC regulations restricting dividend distributions from such reserve funds and from a company's registered capital, our PRC subsidiaries are restricted in their ability to transfer a certain amount of their net assets to us as cash dividends, loans or advances. This restricted portion amounted to $0.2 million as of June 30, 2022.

In addition, our non-consolidated joint venture, SHPL, held an aggregate of $58.1 million in cash and cash equivalents and no bank borrowings as of June 30, 2022. Such cash and cash equivalents are only accessible by us through dividend payments from the joint venture. The level of dividends declared by the joint venture is subject to agreement each year between us and our joint venture partner based on the profitability and working capital needs of the joint venture.

Net Cash used in Operating Activities

Net cash used in operating activities was $71.3 million for the six months ended June 30, 2021, compared to net cash used in operating activities of $89.9 million for the six months ended June 30, 2022. The net change of $18.6 million was primarily attributable to an increase in net loss of $63.6 million from $99.3 million for the six months ended June 30, 2021 to $162.9 million for the six months ended June 30, 2022. The foregoing was partially offset by an increase in changes of working capital of $46.8 million from $11.0 million for the six months ended June 30, 2021 to $57.8 million for the six months ended June 30, 2022.

Net Cash generated from/(used in) Investing Activities

Net cash used in investing activities was $155.9 million for the six months ended June 30, 2021, compared to net cash generated from investing activities of $259.7 million for the six months ended June 30, 2022. The net change of $415.6 million was primarily attributable to short-term investments which had net deposits of $163.5 million for the six months ended June 30, 2021 as compared to net withdrawals of $275.5 million for the six months ended June 30, 2022. The net change was partially offset by the deposit received for the divestment of an equity investee of $15.9 million during the six months ended June 30, 2021.

Net Cash (used in)/generated from Financing Activities

Net cash generated from financing activities was $578.3 million for the six months ended June 30, 2021, compared to net cash used in financing activities of $74.6 million for the six months ended June 30, 2022. The net change of $652.9 million was mainly attributable to net proceeds from issuances of shares of $614.9 million primarily from a private placement in April 2021 and our public offering on the HKEX in June 2021. The net change was also attributable to an increase in purchases of ADSs of $21.3 million by a trustee for the settlement of equity awards of the Company which totaled $26.8 million for the six months ended June 30, 2021 as compared to $48.1 million for the six months ended June 30, 2022, as well as a net decrease in bank borrowings of $26.5 million due to a repayment of bank borrowings of $26.9 million partly offset by proceeds from bank borrowings of $0.4 million during the six months ended June 30, 2022.

LOAN FACILITIES

In November 2018, our subsidiary renewed a three-year revolving loan facility with HSBC(77) . The facility amount of this loan was HK$234.0 million ($30.0 million) with an interest rate at HIBOR(78) plus 0.85% per annum. This credit facility was guaranteed by us and includes certain financial covenant requirements. The revolving loan facility expired in November 2021.

In May 2019, our subsidiary entered into a credit facility arrangement with HSBC for the provision of unsecured credit facilities in the aggregate amount of HK$400.0 million ($51.3 million). The 3-year credit facilities include (i) a HK$210.0 million ($26.9 million) term loan facility and (ii) a HK$190.0 million ($24.4 million) revolving loan facility, both with an interest rate at HIBOR plus 0.85% per annum. These credit facilities are guaranteed by us and include certain financial covenant requirements. The term loan was drawn in October 2019 and was repaid in May 2022. The revolving loan facility also expired in May 2022.

In August 2020, our subsidiary entered into a 24-month revolving credit facility with Deutsche Bank AG(79) in the amount of HK$117.0 million ($15.0 million) with an interest rate at HIBOR plus 4.5% per annum. This revolving facility is guaranteed by us and includes certain financial covenant requirements. As of June 30, 2022, no amount was drawn from the revolving loan facility.

In October 2021, our subsidiary entered into a 10-year fixed asset loan facility agreement with Bank of China Limited for the provision of a secured credit facility in the amount of RMB754.9 million ($113.2 million) with an annual interest rate at the 5-year China Loan Prime Rate less 0.80% (which was supplemented in June 2022). This credit facility is guaranteed by another subsidiary of the Group, and secured by the underlying leasehold land and buildings, and includes certain financial covenant requirements. As of June 30, 2022, RMB2.8 million ($0.4 million) was drawn from the fixed asset loan facility.

In May 2022, our subsidiary entered into a 12-month revolving credit facility with HSBC in the amount of HK$390.0 million ($50.0 million) with an interest rate at HIBOR plus 0.5% per annum. This revolving facility is guaranteed by us. As of June 30, 2022, no amount was drawn from the revolving loan facility.

Our non-consolidated joint venture SHPL had no bank borrowings outstanding as of June 30, 2022.

FOREIGN EXCHANGE RISK

A substantial portion of our revenues and expenses are denominated in renminbi, and our consolidated financial statements are presented in U.S. dollars. We do not believe that we currently have any significant direct foreign exchange risk and have not used any derivative financial instruments to hedge our exposure to such risk. In general, our exposure to foreign exchange risks is limited.

The value of the renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China's political and economic conditions. The conversion of renminbi into foreign currencies, including U.S. dollars, has been based on rates set by the PBOC(80) . If we decide to convert renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the renminbi would have a negative effect on the U.S. dollar amounts available to us. On the other hand, if we need to convert U.S. dollars into renminbi for business purposes, e.g. capital expenditures and working capital, appreciation of the renminbi against the U.S. dollar would have a negative effect on the renminbi amounts we would receive from the conversion. In addition, for certain cash and bank balances deposited with banks in the PRC, if we decide to convert them into foreign currencies, they are subject to the rules and regulations of foreign exchange control promulgated by the PRC government.

CREDIT RISK

Substantially all of our bank deposits are in major financial institutions, which we believe are of high credit quality. We limit the amount of credit exposure to any single financial institution. We make periodic assessments of the recoverability of trade and other receivables and amounts due from related parties. Our historical experience in collection of receivables falls within the recorded allowances, and we believe that we have made adequate provision for uncollectible receivables.

INTEREST RATE RISK

We have no significant interest-bearing assets except for bank deposits. Our exposure to changes in interest rates is mainly attributable to our bank borrowings, which bear interest at floating interest rates and expose us to cash flow interest rate risk. We have not used any interest rate swaps to hedge our exposure to interest rate risk. We have performed sensitivity analysis for the effects on our results for the period from changes in interest rates on floating rate borrowings. The sensitivity to interest rates used is based on the market forecasts available at the end of the reporting period and under the economic environments in which we operate, with other variables held constant. According to the analysis, the impact on our net loss of a 1.0% interest rate shift would be a maximum increase/decrease of $0.1 million for the six months ended June 30, 2022.

OFF-BALANCE SHEET ARRANGEMENTS

We did not have during the periods presented, and we do not currently have, any material off-balance sheet arrangements

CONTINGENT LIABILITIES

Other than as disclosed in note 11 to the interim financial statements, the Group does not have any other significant commitments or contingent liabilities.

GEARING RATIO

The gearing ratio of the Group, which was calculated by dividing total interest-bearing loans by total equity, was 0.05% as of June 30, 2022, a decrease from 2.6% as of December 31, 2021. The decrease was primarily attributable to the decrease in interest-bearing loans.

SIGNIFICANT INVESTMENTS HELD

Except for our investment in a non-consolidated joint venture SHPL with a carrying value of $82.5 million including details below and those as disclosed in note 7 to the interim financial statements, we did not hold any other significant investments in the equity of any other companies as of June 30, 2022.

Our own-brand prescription drugs business under our Other Ventures is operated through SHPL. Dividends received from SHPL for the six months ended June 30, 2022 were $22.7 million.

FUTURE PLANS FOR MATERIAL INVESTMENTS AND CAPITAL ASSETS

Note 11 to the interim financial statements discloses our planned expenditures on capital assets as of June 30, 2022. At this date there were no other plans to incur material expenditures on additional investments or capital assets.

MATERIAL ACQUISITIONS AND DISPOSALS OF SUBSIDIARIES, ASSOCIATES AND JOINT VENTURES

During the six months ended June 30, 2022, we did not have any other material acquisitions and disposals of subsidiaries, associates and joint ventures.

PLEDGE OF ASSETS

Our 10-year fixed asset loan facility agreement with Bank of China Limited is secured by the underlying leasehold land and buildings. RMB2.8 million ($0.4 million) was drawn from the fixed asset loan facility as of June 30, 2022.

INFLATION

In recent years, China has not experienced significant inflation, and thus inflation has not had a material impact on our results of operations. According to the National Bureau of Statistics of China, the Consumer Price Index in China increased by 0.2%, 1.5% and 2.5% in 2020, 2021 and the first half of 2022, respectively. Although we have not been materially affected by inflation in the past, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China.

INTERIM DIVID

The Board does not recommend any interim dividend for the six months ended June 30, 2022.

HUTCHMED (CHINA) LIMITED

Notes to the INTERIM UNAUDITED CONDENSED Consolidated Financial Statements

1. Organization and Nature of Business

HUTCHMED (China) Limited (the "Company") and its subsidiaries (together the "Group") are principally engaged in researching, developing, manufacturing and marketing pharmaceutical products. The Group and its equity investees have research and development facilities and manufacturing plants in the People's Republic of China (the "PRC") and sell their products mainly in the PRC, including Hong Kong. In addition, the Group has established international operations in the United States of America (the "U.S.") and Europe.

The Company's ordinary shares are listed on the Main Board of The Stock Exchange of Hong Kong Limited ("HKEX") and the AIM market of the London Stock Exchange, and its American depositary shares ("ADS") are traded on the Nasdaq Global Select Market.

Liquidity

As at June 30, 2022, the Group had accumulated losses of US$773,189,000 primarily due to its spending in drug research and development activities. The Group regularly monitors current and expected liquidity requirements to ensure that it maintains sufficient cash balances and adequate credit facilities to meet its liquidity requirements in the short and long term. As at June 30, 2022, the Group had cash and cash equivalents of US$467,502,000, short-term investments of US$358,698,000 and unutilized bank borrowing facilities of US$177,814,000. Short-term investments comprised of bank deposits maturing over three months.

Based on the Group's operating plan, the existing cash and cash equivalents, short-term investments and unutilized bank borrowing facilities are considered to be sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months (the look-forward period used).

2. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The interim unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The interim unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments necessary for the fair statement of results for the periods presented, have been included. The results of operations of any interim period are not necessarily indicative of the results of operations for the full year or any other interim period.

The comparative year-end condensed balance sheet data was derived from the annual audited consolidated financial statements, but is condensed to the same degree as the interim condensed balance sheet data.

The interim unaudited condensed consolidated financial statements and related disclosures have been prepared with the presumption that users have read or have access to the annual audited consolidated financial statements for the preceding fiscal year.

The preparation of interim unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the interim unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.

Recent Accounting Pronouncements

Amendments that have been issued by the Financial Accounting Standards Board or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Group's condensed consolidated financial statements.

13. Share-based Compensation

   (i)   Share--based Compensation of the Company 

The Company conditionally adopted a share option scheme on June 4, 2005 (as amended on March 21, 2007) and such scheme has a term of 10 years. It expired in 2016 and no further share options can be granted. Another share option scheme was conditionally adopted on April 24, 2015 (as amended on April 27, 2020) (the "HUTCHMED Share Option Scheme"). Pursuant to the HUTCHMED Share Option Scheme, the Board of Directors of the Company may, at its discretion, offer any employees and directors (including Executive and Non-executive Directors but excluding Independent Non-executive Directors) of the Company, holding companies of the Company and any of their subsidiaries or affiliates, and subsidiaries or affiliates of the Company share options to subscribe for shares of the Company.

As at June 30, 2022, the aggregate number of shares issuable under the HUTCHMED Share Option Scheme was 48,811,458 ordinary shares and the aggregate number of shares issuable under the prior share option scheme which expired in 2016 was 660,570 ordinary shares. The Company will issue new shares to satisfy share option exercises. Additionally, the number of shares authorized but unissued was 635,424,660 ordinary shares.

Share options granted are generally subject to a four-year vesting schedule, depending on the nature and the purpose of the grant. Share options subject to the four-year vesting schedule, in general, vest 25% upon the first anniversary of the vesting commencement date as defined in the grant letter, and 25% every subsequent year. However, certain share option grants may have a different vesting schedule as approved by the Board of Directors of the Company. No outstanding share options will be exercisable or subject to vesting after the expiry of a maximum of eight to ten years from the date of grant.

A summary of the Company's share option activity and related information is as follows:

Note: Includes 861,220 share options (represented by 172,244 ADS) granted to an executive director in May 2022 where the number of share options exercisable is subject to a performance target based on a market condition covering the 3-year period from 2022 to 2024 which has been reflected in estimating the grant date fair value. The grant date fair value of such awards is US$0.24 per share using the Polynomial model. Vesting of such award will occur in March 2025.

In estimating the fair value of share options granted, the following assumptions were used in the Polynomial model for awards granted in the periods indicated:

Notes:

(a) The Company calculated its expected volatility with reference to the historical volatility prior to the issuances of share options.

(b) The risk-free interest rates reference the U.S. Treasury yield curves because the Company's ADS are currently listed on the NASDAQ and denominated in US$.

(c) The Company has not declared or paid any dividends and does not currently expect to do so prior to the exercise of the granted share options, and therefore uses an expected dividend yield of zero in the Polynomial model.

The Company will issue new shares to satisfy share option exercises. The following table summarizes the Company's share option exercises:

As at June 30, 2022, the total unrecognized compensation cost was US$17,673,000, and will be recognized on a graded vesting approach over the weighted average remaining service period of 2.94 years.

   (ii)        LTIP 

The Company grants awards under the LTIP to participating directors and employees, giving them a conditional right to receive ordinary shares of the Company or the equivalent ADS (collectively the "Awarded Shares") to be purchased by the Trustee up to a cash amount. Vesting will depend upon continued employment of the award holder with the Group and will otherwise be at the discretion of the Board of Directors of the Company. Additionally, some awards are subject to change based on annual performance targets prior to their determination date.

LTIP awards prior to the determination date

Performance targets vary by award, and may include targets for shareholder returns, financings, revenues, net profit after taxes and the achievement of clinical and regulatory milestones. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management's assessment on the achievement of the performance target has been assigned to calculate the amount to be recognized as an expense over the requisite period with a corresponding entry to liability.

LTIP awards after the determination date

Upon the determination date, the Company will pay a determined monetary amount, up to the maximum cash amount based on the actual achievement of the performance target specified in the award, to the Trustee to purchase the Awarded Shares. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no Awarded Shares of the Company will be purchased and the amount previously recorded in the liability will be reversed through share-based compensation expense.

Granted awards in 2021 and 2022 under the LTIP are as follows:

 
                       Maximum cash amount         Covered         Performance target

Notes:

(a) The annual performance target determination date is the date of the announcement of the Group's annual results for the covered financial year and vesting occurs two business days after the announcement of the Group's annual results for the financial year falling two years after the covered financial year to which the LTIP award relates.

(b) This award does not stipulate performance targets and is subject to a vesting schedule of 25% on each of the first, second, third and fourth anniversaries of the date of grant.

(c) This award does not stipulate performance targets and will be vested on the first anniversary of the date of grant.

The Trustee has been set up solely for the purpose of purchasing and holding the Awarded Shares during the vesting period on behalf of the Company using funds provided by the Company. On the determination date, if any, the Company will determine the cash amount, based on the actual achievement of each annual performance target, for the Trustee to purchase the Awarded Shares. The Awarded Shares will then be held by the Trustee until they are vested.

The Trustee's assets include treasury shares and funds for additional treasury shares, trustee fees and expenses. The number of treasury shares (in the form of ordinary shares or ADS of the Company) held by the Trustee were as follows:

15. In-Licensing Arrangement

On August 7, 2021, the Group and Epizyme, Inc. ("Epizyme") entered into a license agreement (the "In-license Agreement") for tazemetostat, a novel inhibitor of EZH2 that is approved by the U.S. Food and Drug Administration for the treatment of certain patients with epithelioid sarcoma and follicular lymphoma. The Group will be responsible for the development and commercialization of tazemetostat in the PRC, Hong Kong, Macau and Taiwan (the "Territory") and also holds rights to manufacture tazemetostat for the Territory. The Group also received a 4-year warrant, exercisable up to August 7, 2025, to purchase up to 5,653,000 shares of Epizyme common stock for an exercise price of US$11.50 per share ("Warrant Exercise Price").

Under the terms of the In-license Agreement and warrant, the Group paid Epizyme a US$25 million upfront payment and is obligated for a series of success-based payments up to US$110 million in development and regulatory milestones and up to US$175 million in sales milestones. Success-based payments are recognized when the related milestone is achieved. After tazemetostat is commercialized in the Territory, the Group will incur tiered royalties based on net sales. As at June 30, 2022, no amounts of development and regulatory milestones, sales milestones or royalties had been paid.

The US$25 million upfront payment was first allocated to the warrant for its initial fair value of US$15 million, and the remainder was allocated to the rights to tazemetostat which were expensed to research and development expense as in-process research and development.

The warrant was recorded as a financial asset at fair value with changes to fair value recognized to the condensed consolidated statements of operations. In June 2022, Epizyme announced it had entered a definitive merger agreement under which a third party would acquire all its outstanding shares for an amount per share less than the Warrant Exercise Price. Consequently, as at June 30, 2022, there was no fair value attributed to the warrant. For the six months ended June 30, 2022, a fair value loss of US$2.5 million was recognized to other expenses in the condensed consolidated statements of operations.

19. Losses Per Share

   (i)   Basic losses per share 

Basic losses per share is calculated by dividing the net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the period. Treasury shares held by the Trustee are excluded from the weighted average number of outstanding ordinary shares in issue for purposes of calculating basic losses per share.

 
                                                                   Six Months Ended June 30, 
                                                                  ---------------------------

                                                                  -------------  ------------ 
Weighted average number of outstanding ordinary shares in issue     849,283,553   729,239,181 
                                                                  =============  ============ 
Net loss attributable to the Company (US$'000)                        (162,861)     (102,397) 
Losses per share attributable to the Company (US$ per share)             (0.19)        (0.14) 
 

(ii) Diluted losses per share

Diluted losses per share is calculated by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the period. Dilutive ordinary share equivalents include shares issuable upon the exercise or settlement of share options and LTIP awards issued by the Company using the treasury stock method.

For the six months ended June 30, 2022 and 2021, the share options and LTIP awards issued by the Company were not included in the calculation of diluted losses per share because of their anti-dilutive effect. Therefore, diluted losses per share were equal to basic losses per share for the six months ended June 30, 2022 and 2021.

22. Litigation

From time to time, the Group may become involved in litigation relating to claims arising from the ordinary course of business. The Group believes that there are currently no claims or actions pending against the Group, the ultimate disposition of which could have a material adverse effect on the Group's results of operations, financial position or cash flows. However, litigation is subject to inherent uncertainties and the Group's view of these matters may change in the future. When an unfavorable outcome occurs, there exists the possibility of a material adverse impact on the Group's financial position and results of operations for the periods in which the unfavorable outcome occurs, and potentially in future periods.

On May 17, 2019, Luye Pharma Hong Kong Ltd. ("Luye") issued a notice to the Group purporting to terminate a distribution agreement that granted the Group exclusive commercial rights to Seroquel in the PRC for failure to meet a pre-specified target. The Group disagrees with this assertion and believes that Luye have no basis for termination. As a result, the Group commenced legal proceedings in 2019 in order to seek damages. On October 21, 2021 (and a decision on costs and interest in December 2021), the Group was awarded an amount of RMB253.2 million (equivalent to US$38.0 million) with interest of 5.5% per annum from the date of the award until payment and recovery of costs of approximately US$2.2 million (collectively the "Award"). On June 27, 2022, Luye provided the Group a bank guarantee of up to RMB286.0 million to cover the Award amounts, pending the outcome of an application by Luye to the High Court of Hong Kong to set aside the Award. On July 26, 2022, Luye's application to set aside the Award was dismissed by the High Court with costs awarded in favor of the Group and if Luye does not appeal the dismissal, the Group will be seeking to enforce the Award by drawing down on the bank guarantee. No Award amounts have been received as at the issuance date of these condensed consolidated financial statements. Hence no Award amounts have been recognized and no adjustment has been made to Seroquel-related balances as at June 30, 2022. Such Seroquel-related balances include accounts receivable, long-term prepayment, accounts payable and other payables of US$1.1 million, US$0.6 million, US$0.9 million and US$1.2 million respectively.

23. Subsequent Events

The Group evaluated subsequent events through August 1, 2022, which is the date when the interim unaudited condensed consolidated financial statements were issued.

24. Reconciliation between U.S. GAAP and International Financial Reporting Standards

These interim unaudited condensed consolidated financial statements are prepared in accordance with U.S. GAAP, which differ in certain respects from International Financial Reporting Standards ("IFRS"). The effects of material differences prepared under U.S. GAAP and IFRS are as follows:

Notes:

   (a)        Lease amortization 

Under U.S. GAAP, for operating leases, the amortization of right-of-use assets and the interest expense element of lease liabilities are recorded together as lease expenses, which results in a straight-line recognition effect in the condensed consolidated statements of operations.

Under IFRS, all leases are accounted for like finance leases where right-of-use assets are generally depreciated on a straight-line basis while lease liabilities are measured under the effective interest method, which results in higher expenses at the beginning of the lease term and lower expenses near the end of the lease term.

   (b)        Issuance costs 

Under U.S. GAAP and IFRS, there are differences in the criteria for capitalization of issuance costs incurred in the offering of equity securities.

   (c)        Divestment of an equity investee 

Under U.S. GAAP, an equity method investment to be divested that does not qualify for discontinued operations reporting would not qualify for held-for-sale classification. The investment in HBYS was not presented as a discontinued operation or as an asset classified as held-for-sale after the signing of the sale and purchase agreement in March 2021 and therefore, it was accounted for under the equity method until closing on September 28, 2021.

Under IFRS, an equity method investment may be classified as held-for-sale even if the discontinued operations criteria are not met. The investment in HBYS was not presented as a discontinued operation but was classified as held-for-sale and therefore equity method accounting was discontinued in March 2021 on the initial classification as held-for-sale. Accordingly, the reconciliation includes a classification difference in the interim unaudited condensed consolidated statement of operations between equity earnings of equity investees, net of tax and income tax expense.

   (d)        Capitalization of development and commercial rights 

Under U.S. GAAP, the acquired development and commercial rights do not meet the capitalization criteria as further development is needed as of the acquisition date and there is no alternative future use. Such rights are considered as in-process research and development and were expensed to research and development expense.

Under IFRS, the acquired development and commercial rights were capitalized to intangible assets. The recognition criterion is always assumed to be met as the price already reflects the probability that future economic benefits will flow to the Group.

   (e)        LTIP classification 

Under U.S. GAAP, LTIP awards with performance conditions are classified as liability-settled awards prior to the determination date as they settle in a variable number of shares based on a determinable monetary amount, which is determined upon the actual achievement of performance targets. After the determination date, the LTIP awards are reclassified as equity-settled awards.

Under IFRS, LTIP awards are classified as equity-settled awards, both prior to and after the determination date, as they are ultimately settled in ordinary shares or the equivalent ADS of the Company instead of cash.
