2023 Full Year Results & Business Updates

Mr Simon To, Executive Chairman of HUTCHMED, said, "We have made significant progress throughout 2023. We executed against our commitment to bring our innovative medicines to patients worldwide with the U.S. FDA approval of FRUZAQLA™ in November 2023, while remaining dedicated to becoming a self-sustaining business. The Takeda partnership, which is one of the biggest small-molecule overseas licensing deals in the history of China biotech, strengthened our cash position by $435 million. Takeda delivered a successful U.S. launch within 48 hours of approval, and has subsequently seen strong early patient uptake."

"We will continue to deliver on our strategy in 2024. We will stay focused on our target of becoming sustainable through our balanced strategy of growing sales of our novel medicines in China, and advancing our medicines overseas with our partners. This, when combined with our other goals on pipeline progression and further business development, means that while the global macroeconomic environment remains uncertain, HUTCHMED is positioned to thrive and continue to deliver innovative medicines to ever more patients around the world."

Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said, "HUTCHMED delivered impressive financial results in 2023, with revenue up 97% to $838 million. This, alongside our significantly strengthened cash balance of $886 million, will enable us to continue advancing our pipeline and successfully executing our strategy."

"2023 was an important year for HUTCHMED, particularly for fruquintinib, for which we filed market authorization applications in the U.S., EU and Japan, based on the successful FRESCO-2 study. Following the U.S. FDA approval for third-line patients with advanced CRC, we continue to work together with Takeda to pursue additional launches in new markets worldwide. In China, we also filed an NDA for second-line gastric cancer based on the FRUTIGA study."

"Another milestone was the successful ESLIM-01 registration study in China in ITP patients for sovleplenib, our first potential novel medicine in immunological diseases. The NDA was accepted and granted priority review by the NMPA in January 2024. There are over 250,000 new and existing adult ITP patients in China²⁰. The treatment options are limited to steroids and TPO/TPO-RAs²¹, representing an unmet medical need that sovleplenib could help address, with its new mechanism of action and favorable safety profile. Syk inhibition has the potential to target other major diseases such as rheumatoid arthritis. We are also planning to initiate clinical development of sovleplenib outside China in 2024."

"For savolitinib, we completed the confirmatory trial in NSCLC patients with MET²² exon 14 skipping alterations. An NDA submission is expected in the first quarter of 2024, with potential to expand the label indication to include first-line patients in China. Outside China, we will continue our work with AstraZeneca on the pivotal global savolitinib lung cancer trial SAVANNAH, which, subject to favorable data, can support a filing to the U.S. FDA for approval. This study completed enrollment with a potential NDA submission towards the end of 2024 in EGFR²³ mutant NSCLC patients who progressed on TAGRISSO^® treatment, which received U.S. FDA Fast Track designation in January 2023. We believe the convenient dosing, targeted efficacy and safety profile of savolitinib as an oral medicine in combination with TAGRISSO^®, the leading oral third-generation EGFR TKI²⁴, should position it well in a competitive market and address the unmet needs of MET+ NSCLC patients."

"Our China commercialization efforts progressed well, as we successfully renewed NRDL²⁵ coverage for both fruquintinib and surufatinib without further price reduction. Their in-market sales saw strong growth in 2023. Over the next two years, we plan to continue growth in China through expanded indications and the launch of new products together with revenue from FRUZAQLA™ overseas commercialization."

While restrictive measures related to COVID-19 were gradually lifted in China starting from December 2022, COVꞮD-19 had some impact on our research, clinical studies and our commercial activities in the first few months of 2023. Measures were put in place to reduce the impact and, in the second quarter of 2023, these activities normalized.

Financial Highlights

Foreign exchange impact: The RMB depreciated against the U.S. dollar on average by approximately 5% during 2023, which has impacted our consolidated financial results as highlighted below.

Cash, Cash Equivalents and Short-Term Investments were $886.3 million as of December 31, 2023 compared to $631.0 million as of December 31, 2022.

· Adjusted Group (non-GAAP⁴⁷) net cash flows excluding financing activities in 2023 were $206.7 million (2022: -$297.9m) mainly due to the receipt of $435 million in upfront and milestone payments from Takeda; and

· Net cash generated from financing activities in 2023 totaled $48.7 million mainly due to the drawdowns of bank borrowings (2022: net cash used in financing activities of $82.8m).

Outlook and FINANCIAL GUIDANCE

2023 was an impressive year for HUTCHMED, in large part due to the upfront payment of $400 million received from Takeda, of which $280 million was recognized in revenue during 2023, with the remainder to be recognized when services and performance obligations are completed over approximately three years.

Full year 2024 guidance for Oncology/Immunology consolidated revenue is $300 million to $400 million, driven by 30% to 50% growth target in oncology marketed product revenue.

HUTCHMED's work in 2024 and beyond will be supported by its strong balance sheet, which grew by $255 million to $886 million in Cash, Cash Equivalents and Short-Term Investments as of December 31, 2023. The Company is thus well placed to deliver against its target to become a self-sustaining business and its goal to bring its innovative medicines to patients globally through its own sales network in China markets and through partners worldwide.

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 900 scientists and staff (December 31, 2022: ~960), and an in-house oncology commercial organization of approximately 930 staff (December 31, 2022: ~870).

We have 13 oncology drug candidates in clinical trials. Three of our medicines, fruquintinib, surufatinib and savolitinib, have all been approved and launched in mainland China with fruquintinib also approved in the U.S., Hong Kong and Macau. Our fourth medicine, tazemetostat, has been approved and launched in Hainan Pilot Zone and Macau.

MARKETED PRODUCT SALES

Despite some initial challenges in the first quarter of the year due to the impact of COVID-19 and impact from an anti-corruption crackdown of the healthcare sector in China from the third quarter onwards, in-market sales of HUTCHMED's novel oncology products continued to grow at 28% (35% at CER) to $213.6 million (2022: $167.1m) in 2023.

Fruquintinib (ELUNATE^® in China, FRUZAQLA™ in the U.S.)

ELUNATE^® is approved for the treatment of third-line metastatic CRC for which there is an approximate incidence of 105,000 new patients per year in China. In 2023, ELUNATE^® in China achieved in-market sales of $107.5 million, up 15% (22 % at CER) versus 2022 ($93.5 million). In China, ELUNATE^® is the leading treatment for late-stage CRC with 47% of 3L treated patient share according to an IQVIA tracking study in Q2 2023.

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^® in China. We consolidate as revenue approximately 70-80% of ELUNATE^® in-market sales from manufacturing fees, service fees and royalties paid to us by Lilly. In 2023, we consolidated $83.2 million in revenue for ELUNATE^®, equal to 77% of in-market sales.

Following negotiations with the China NHSA⁵¹, ELUNATE^® continues to be included in the NRDL for a new two-year term starting in January 2024 at the same price as the 2023 NRDL price.

Takeda launched FRUZAQLA™ in the U.S. within 48 hours after it was approved for previously-treated metastatic CRC on November 8, 2023, with the first prescription received a day after approval. According to Takeda, uptake has been strong, with new patient starts exceeding expectations, and additional regulatory applications progressing as expected including in the EU and Japan. Since its launch until the end of 2023, FRUZAQLA™ achieved in-market U.S. sales of $15.1 million.

This U.S. patient uptake was in parallel to the rapid inclusion of fruquintinib to the 2023 "NCCN Clinical Practice Guidelines for Colon Cancer" and the 2023 "NCCN Clinical Practice Guidelines for Rectal Cancer" on November 16, 2023. Fruquintinib has also been successfully recommended in six other major treatment guidelines for colorectal cancer. These will continue to drive awareness and usage of fruquintinib among doctors and patients.

In January 2024, ELUNATE^® was approved in the Hong Kong Special Administrative Region. This was the first medicine to be approved under the new mechanism for registration of new drugs ("1+" mechanism). CRC was the second most common cancer in Hong Kong in 2021, with about 5,900 new patients diagnosed and associated with about 2,300 deaths.

Surufatinib (SULANDA^® in China)

SULANDA^® was launched in China in 2021 for the treatment of all advanced NETs⁵² for which there is an approximate incidence of 34,000 new patients per year in China.

Total in-market sales in 2023 increased by 36% (43% at CER) to $43.9 million (2022: $32.3 million). According to IQVIA tracking study report in Q4 2023, SULANDA^® maintained its position in the market with 21% prescription share in NET treatment, ahead of competitors SUTENT^® and AFINITOR^®.

Following negotiations with the China NHSA, SULANDA^® continues to be included in the NRDL for a new two-year term starting in January 2024, at the same price as the 2023 NRDL price.

Surufatinib has been successfully recommended in 2023 "Chinese medical association consensus for standardized diagnosis and treatment of pancreatic cancer neuroendocrine neoplasms" and four other treatment guidelines for neuroendocrine tumors. As a result, doctors' acceptance and patients' access to SULANDA^® continue to increase.

Savolitinib (ORPATHYS^® in China)

ORPATHYS^® is the first-in-class selective MET inhibitor to be approved in China, launched and marketed by our partner, AstraZeneca for patients with MET exon 14 skipping alteration NSCLC. More than a third of the world's lung cancer patients are in China. Among those with NSCLC globally, approximately 2-3% have tumors with MET exon 14 skipping alterations.

In 2021, 2022 and the first two months of 2023, ORPATHYS^® was sold as a self-pay drug. Following negotiations with the China NHSA in January 2023, ORPATHYS^® has been included in the updated NRDL since March 1, 2023 at a 38% discount relative to the self-pay price, broadening patient access to this medicine. Sales in 2023 were impacted by customary channel fluctuations following the announcement (in January 2023) and implementation of the NRDL listing (in March 2023), with increased volume in the latter part of 2023. In-market sales for ORPATHYS^® increased 12% (increased 19% at CER) in 2023 to $46.1 million (2022: $41.2m) resulting in our consolidation of $28.9 million (2022: $22.3m) in revenue primarily from drug product supply and royalties. Sales in the second, third and fourth quarters of 2023 were substantially higher than during the same period in 2022 before NRDL listing, increasing 104% by volume.

Market understanding of the need for MET testing has improved significantly, with approximately half of new advanced/relapsed NSCLC patients in China being tested. 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^® was identified as the only targeted therapy recommended for MET exon 14 patients, while a similar guideline from CSCO⁵³ also recommended ORPATHYS^® as the standard of care for such patients. As MET testing awareness and access increases, more patients are expected to be prescribed a selective MET inhibitor.

In March 2023, ORPATHYS^® was also approved in the Macau Special Administrative Region.

Tazemetostat (TAZVERIK^® in Hainan and Macau, China; the U.S. and Japan)

In May 2022, TAZVERIK^® 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. Tazemetostat was included in the 2022 CSCO guidelines for epithelioid sarcoma. 16 epithelioid sarcoma patients began treatment in 2023 (2022: 3). Tazemetostat is included in the 2023 CSCO guideline for follicular lymphoma.

In March 2023, TAZVERIK^® was approved in the Macau Special Administrative Region.

RESEARCH & DEVELOPMENT

With U.S. FDA approval of fruquintinib in November 2023, we now possess a track record of discovery, clinical development and marketing approval of an innovative medicine in the global market.

Our strategy is aimed at accelerating our path to establish a long-term sustainable business, by prioritizing late-stage and registrational studies in China and partnering outside of China. HUTCHMED intends to continue to run early phase development programs for selected drug candidates internationally where we believe we can differentiate from a global perspective.

Below is a summary update of the clinical trial progress of our investigational drug candidates. For more details about each trial, please refer to recent scientific publications.

Savolitinib (ORPATHYS^® in China)

Savolitinib is an oral, potent, and highly selective oral inhibitor of MET. In global partnership with AstraZeneca, savolitinib is being studied in NSCLC, PRCC⁵⁴ and gastric cancer clinical trials with about 2,500 patients to date, both as a monotherapy and in combinations. AstraZeneca has paid HUTCHMED $85 million of the total $140 million in upfront payments, development and approval milestones that are potentially payable under the relevant license and collaboration agreement.

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^®. Among patients who experience disease progression post-TAGRISSO^® 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 (NCT02143466) and SAVANNAH (NCT03778229) studies. The encouraging results led to the initiation of three Phase III studies: SACHI and SANOVO were initiated in China in 2021, and the global, pivotal Phase III SAFFRON study started enrollment in 2022.

Savolitinib - NSCLC updates:

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

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
Savolitinib + TAGRISSO^®	SAVANNAH: 2L/3L EGFRm+⁵⁵; TAGRISSO^® refractory; MET+	Global	II Registration-intent	Fully enrolled	NCT03778229
Savolitinib + TAGRISSO^®	SAFFRON: 2L/3L EGFRm+; TAGRISSO^® refractory; MET+	Global	III	Ongoing since 2022	NCT05261399
Savolitinib + TAGRISSO^®	SACHI: 2L EGFR TKI refractory NSCLC; MET+	China	III	Ongoing since 2021	NCT05015608
Savolitinib + TAGRISSO^®	SANOVO: Naïve patients with EGFRm & MET+	China	III	Ongoing since 2021	NCT05009836
Savolitinib monotherapy	MET exon 14 skipping alterations	China	II Registration	Approved & launched in 2021; Final OS analysis at ELCC⁵⁶ 2022	NCT02897479
Savolitinib monotherapy	MET exon 14 skipping alterations	China	IIIb Confirmatory	Fully enrolled in H1 2023; 1L cohort data at WCLC⁵⁷ 2023	NCT04923945
Savolitinib + IMFINZI^®	SOUND: MET-driven, EGFR wild type	China	II	Ongoing since 2022	NCT05374603

The SAVANNAH global Phase II study in patients who have progressed following TAGRISSO^® due to MET amplification or overexpression has completed recruitment. In January 2023, the U.S. FDA designated as a Fast Track development program the investigation of savolitinib for use in combination with TAGRISSO^® for the treatment of patients with locally advanced or metastatic NSCLC whose tumors have MET overexpression and/or amplification, as detected by an FDA-approved test, and who have had disease progression during or following prior TAGRISSO^®. We continue to evaluate the possibility of using the SAVANNAH study as the basis for U.S. accelerated approval. In comparison to other treatments options, this treatment is chemotherapy-free, biomarker-specific and orally administered, aiming for a balanced efficacy, safety and quality-of-life profile for lung cancer patients.

The SAFFRON study, which will evaluate the efficacy and safety of savolitinib in combination with TAGRISSO^® compared to pemetrexed plus platinum doublet-chemotherapy, has now activated a majority of the approximately 250 sites in over 20 countries planned for the study.

Two registrational studies are ongoing in China in EGFR mutated NSCLC with MET aberrations: the SANOVO study in treatment naïve patients, and SACHI study in patients whose disease progressed following treatment with any first-line EGFR TKI. Both trials are expected to complete enrollment in 2024.

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). A confirmatory Phase IIIb study in this patient population fully enrolled in H1 2023 (NCT04923945). Results from the first-line cohort of this study were disclosed at WCLC 2023. At data cut-off date of April 30, 2023, among the 84 patients in the tumor response evaluable set (TRES), ORR was 60.7% (95% CІ: 49.5% to 71.2%) and DCR was 95.2% (95% CІ: 88.3% to 98.7%), as assessed by an independent review committee. At median follow-up of 11.1 months, median PFS was 13.8 months (95% CІ: 9.7 months to not reached). Median DoR and OS have not been reached. No new safety signals were observed.

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.

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
Savolitinib	3L gastric cancer with MET amplification. Two-stage, single-arm study	China	II registration-intent	~64 patient registration cohort enrolling since March 2023; Breakthrough Therapy Designation	NCT04923932

Preliminary efficacy and safety data from an interim analysis of 20 patients in a Phase II trial of savolitinib monotherapy in patients with MET-amplified advanced or metastatic gastroesophageal junction adeno-carcinomas or gastric cancer was reported at AACR 2023, showing promising efficacy in patients with MET-amplified diseases, particularly in patients with high MET gene copy number. Confirmed ORR by independent review was 45%, or 50% in the 16 patients with high MET gene copy number. DoR rate at 4-months was 85.7%. The most common grade 3 or above TRAEs⁵⁸ (more than 5%) were decreased platelet count, hypersensitivity, anemia, neutropenia and abnormal hepatic function. The BID⁵⁹ regimen is being investigated to further evaluate the efficacy and safety of savolitinib in MET high patients. Following consultation with the NMPA with this data, a patient registration cohort began enrolling in March 2023.

Savolitinib - Kidney cancer:

MET is a key genetic driver in PRCC. 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. Savolitinib has been studied in multiple global studies in PRCC patients, including the SAVOIR monotherapy and CALYPSO combination therapy global Phase II trials, that both demonstrated highly encouraging results. 24-month follow-up of CALYPSO trial (NCT02819596) showed median PFS of 15.7 months and median OS of 27.4 months in MET-driven PRCC patients. These results led to the initiation of a global Phase III, the SAMETA study, in 2021. Over 140 sites in over 20 countries are enrolling patients.

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
Savolitinib + IMFINZI^®	SAMETA: MET-driven, unresectable and locally advanced or metastatic PRCC	Global	III	Ongoing since 2021	NCT05043090

Fruquintinib (ELUNATE^® in China, FRUZAQLA™ in the U.S.)

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 efficacy and tolerability. Fruquintinib has been studied in clinical trials with about 5,700 patients to date, both as a monotherapy and in combination with other agents.

Aside from its first approved indication of previously-treated metastatic CRC (in China and the U.S.), studies of fruquintinib combined with various checkpoint inhibitors (including TYVYT^® and tislelizumab) are underway. Registration-intent studies combined with chemotherapy (FRUTIGA study in gastric cancer) or checkpoint inhibitors (TYVYT^® combo, in endometrial cancer and RCC) are ongoing in China.

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

Fruquintinib - CRC updates:

FRESCO-2 (NCT04322539) - Positive results from this double-blind, placebo-controlled, global Phase III study in 691 patients demonstrated that treatment with fruquintinib resulted in a statistically significant and clinically meaningful increase in OS and the key secondary endpoint of PFS compared to treatment with placebo. ASCO presentations showed that in subgroup analyses by prior lines of therapies up to six or more and by prior treatment with approved agents, fruquintinib improved OS and PFS for all subgroups and prior therapies, consistent with those of the overall study population. A separate study showed that during the study adverse events of special interest led to low rates of dose reduction (13.6% for patients who received fruquintinib vs 0.9% for patients who received placebo) and dose discontinuation (8.3% for patients who received fruquintinib vs 6.1% for patients who received placebo).

Filing of a rolling submission of an NDA was accepted by the FDA in May 2023 for priority review, with PDUFA date of November 30, 2023. Fruquintinib (FRUZAQLA™ in the U.S.) was approved by the FDA on November 8, 2023. The MAA filing to the EMA was validated in June 2023. The NDA was submitted to the Japan PMDA in September 2023.

On January 26, 2024, fruquintinib obtained the marketing approval from the Pharmacy and Poisons Board of Hong Kong for the treatment of adult patients with previously treated metastatic CRC. This marked the first medicine to be approved under the new mechanism for registration of new drugs ("1+" mechanism) officially commenced on November 1, 2023. It allows drugs which are beneficial for treatment of life-threatening or severely debilitating diseases to apply for registration for use in Hong Kong, if they have supporting local clinical data and recognition from relevant experts, when they have been approved by only one reference drug regulatory authority (instead of two otherwise). CRC was the second most common cancer in Hong Kong in 2021.

China Phase IV (NCT04005066) - Results presented at ASCO 2023 from a prospective, 3,005-patient study to evaluate the safety of fruquintinib in real-world clinical practice in China are consistent with the fruquintinib safety profile observed in existing clinical studies, with no new or significant safety signals identified.

Fruquintinib - Gastric cancer updates:

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. The trial met the PFS endpoint at a statistically and clinically meaningful level. The OS endpoint was not statistically significant per the pre-specified statistical plan, although there was an improvement in median OS.

Results were presented orally at ASCO Plenary Series in February 2024. Patients on fruquintinib combined with paclitaxel achieved median PFS of 5.6 months, vs 2.7 months in the control group on paclitaxel only with HR of 0.569 and p < 0.0001. There was a numerical improvement in OS, with median OS of 9.6 months vs. 8.4 months; however, this was not statistically significant. There was an imbalance of patients receiving subsequent antitumor therapies across the two groups, with 52.7% in the fruquintinib plus paclitaxel group vs. 72.2% in the paclitaxel monotherapy group. In a pre-specified sensitivity analysis, when excluding patients taking subsequent antitumor therapy, OS improvement was statistically significant for the treatment arm at 6.9 months vs 4.8 months in the control arm with HR of 0.72 and p=0.0422. Fruquintinib also demonstrated a statistically significant improvement in secondary endpoints including ORR, DCR and DoR. The safety profile of fruquintinib in FRUTIGA was consistent with previously reported studies.

In April 2023, the NDA in China was accepted for review by the NMPA.

Fruquintinib - Combinations with checkpoint inhibitors updates:

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

We agreed with the NMPA to expand this cohort into a single-arm registrational Phase II study. In July 2023, the cohort fully enrolled and was granted Breakthrough Therapy Designation. If the study results are positive, we expect to file the NDA with the NMPA in this treatment setting in mid-2024.

Advanced metastatic clear-cell RCC (NCT05522231) - In first-line clear-cell RCC, clinical benefits have been demonstrated for the combination of antiangiogenic therapy and immunotherapy. However, there is limited evidence on the benefits of this combination in the second-line setting. Phase II (NCT03903705) data disclosed at ASCO 2023 showed encouraging anti-tumor efficacy and durability in these patients. PFS results from this exploratory study of the fruquintinib and sintilimab combination in metastatic clear-cell RCC were reported. At data cut-off on November 30, 2022, median PFS was 15.9 months in 20 previously treated patients. No new safety signals were observed.

A Phase II/III trial of fruquintinib in combination with TYVYT^® as second-line treatment for locally advanced or metastatic RCC was initiated in October 2022. The study is a randomized, open-label, active-controlled study to evaluate the efficacy and safety of fruquintinib in combination with TYVYT^® versus axitinib or everolimus monotherapy for the second-line treatment of advanced RCC. The primary endpoint is PFS. The enrollment was completed in December 2023. A total of 234 patients have been enrolled in the study. We expect to announce topline results around year end 2024.

Fruquintinib - Exploratory development:

In China, we support an investigator-initiated trial program for fruquintinib, and there are about 90 of such trials ongoing in various solid tumor settings. A number of investigator-initiated trials were presented at ASCO 2023, ESMO 2023 and ASCO GI 2024, including initial results of a Phase II study of fruquintinib in combination with investigator's choice of chemotherapy in second-line metastatic CRC with microsatellite stable (MSS) phenotype, as well as fruquintinib monotherapy for the treatment of biliary tract cancer and soft tissue sarcoma.

Fruquintinib - Partnership with Takeda:

In March 2023, HUTCHMED completed an exclusive worldwide license to Takeda to develop and commercialize fruquintinib in all indications and territories outside of mainland China, Hong Kong and Macau, where it is marketed and will continue to be marketed by HUTCHMED in partnership with Lilly. Subject to the terms of the agreement, HUTCHMED is eligible to receive up to $1.13 billion. This includes $400 million which was received in April 2023 on closing of the agreement, and up to $730 million in additional potential payments relating to regulatory, development and commercial sales milestones, of which a $35 million milestone payment was received in December 2023 for the approval by the U.S. FDA. HUTCHMED is also eligible to receive royalties on net sales.

Surufatinib (SULANDA^® 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 2,900 patients to date, both as a monotherapy and in combinations, and is approved in China. HUTCHMED currently retains rights to surufatinib worldwide.

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 + TUOYI^® (PD-1)	SCLC	China	II	Fully enrolled	NCT05509699

Ex-China regulatory discussions - 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. While discussions in 2020 suggested that two positive Phase III studies of surufatinib in patients with pNETs and epNETs in China could form the basis to support a U.S. NDA submission, this was ultimately not accepted. A new multi-regional clinical trial (MRCT) would be required to move forward with this program in the U.S., Europe and Japan. Following dialogue with the Japanese PMDA, we have decided not to file a Japanese NDA on the basis of the clinical trial data available at this time.

Surufatinib - Combination therapy with checkpoint inhibitors:

A Phase II China study (NCT04169672) combining surufatinib with TUOYI^® enrolled patients in nine solid tumor types. 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 a Phase II study in SCLC in 2022.

We reported the results from the advanced endometrial cancer cohorts at ASCO 2023. Amongst efficacy evaluable endometrial cancer patients, median PFS was 5.4 months and 12-month OS rate was 71.0% (median follow-up duration was 16.8 months). The combination showed a tolerable safety profile. Additionally, results from the NSCLC cohort were presented at AACR 2023 demonstrating promising anti-tumor activity in first-line setting for advanced PD-L1 positive NSCLC patients with manageable toxicity.

Surufatinib - Exploratory development:

In China, we support an investigator-initiated trial program for surufatinib, with about 110 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. A number of investigator-initiated trials were presented at ASCO 2023, ESMO 2023 and ASCO GI 2024 for surufatinib in combination with other agents, including with chemotherapy as well as with anti-PD-1 antibodies plus different chemotherapy regimens in various solid types including pancreatic adenocarcinoma, gastric/gastroesophageal junction adenocarcinoma and biliary tract cancer. In one of these trials (NCT05218889) using surufatinib in combination with camrelizumab (an anti-PD-1) plus chemotherapy in first-line therapy for pancreatic adenocarcinoma, median PFS and OS were 9.2 months and 15.6 months, respectively, compared to 6.3 months and 8.6 months in the control group with chemotherapy only.

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. Sovleplenib has been studied in clinical trials with around 600 patients to date.

In December 2022, we completed recruitment of a Phase III study in China for primary ITP, for which it has received Breakthrough Therapy designation. Positive proof of concept data was reported on primary ITP at ASH⁷⁷ 2021 and published in Lancet Hematology in April 2023. In 2024, we plan to start a dose-finding study in the U.S. HUTCHMED currently retains all rights to sovleplenib worldwide. The table below shows a summary of the clinical studies for sovleplenib.

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #

Sovleplenib monotherapy	Warm AIHA	China	II/III	Phase II fully enrolled; Phase III expected in early 2024	NCT05535933

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 188 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. All endpoints were met in August 2023 and the NDA has been accepted for review and granted priority review by the NMPA in January 2024. We plan to submit the results for presentation and/or publication in mid-2024.

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. The first patient was enrolled in September 2022. The enrollment of Phase II part of the study was completed in mid-2023 and primary end point has been met. We expect to initiate Phase III in early-2024.

Tazemetostat

In August 2021, we entered into a strategic collaboration with Epizyme, a subsidiary of Ipsen, 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 Ipsen 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. Tazemetostat has been studied in clinical trials with around 1,300 patients to date.

We are developing and plan to seek approval for tazemetostat in various hematological and solid tumors in China. We are participating in Ipsen's SYMPHONY-1 (EZH-302) study, leading it in China. We are generally responsible for funding all clinical trials of tazemetostat in China, including the portion of global trials conducted there. Separately, we are conducting a China bridging study in follicular lymphoma for potential conditional registration based on its U.S. approvals. The study is fully enrolled and, subject to the data, we plan to file the NDA in China in mid-2024. We are responsible for the research, manufacturing and commercialization of tazemetostat in China. Tazemetostat was approved in China Hainan Pilot Zone in 2022 and the Macau Special Administrative Region in 2023.

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

SYMPHONY-1 Global Phase Ib/III combination study in relapsed/refractory follicular lymphoma with ≥2 prior therapies (NCT04224493) - The Phase Ib open-label portion of SYMPHONY-1 recruited 44 patients and showed ORR of 90.9%. In the 800-mg BID recommended Phase III dose cohort, 18-month PFS and DOR estimates were 94.4% and 100%. There were no dose-limiting toxicities.

HMPL-453

HMPL-453 is a novel, selective, oral inhibitor targeting FGFR 1/2/3. Aberrant FGFR signaling is associated with tumor growth, promotion of angiogenesis, as well as resistance to anti-tumor therapies. Approximately 10-15% of IHCC patients globally have tumors harboring FGFR2 fusion. HUTCHMED currently retains all rights to HMPL-453 worldwide. The table below shows a summary of the clinical studies for HMPL-453.

HMPL-453 +TUOYI^® (PD‑1)	Multiple	China	I/II	Ongoing since 2022	NCT05173142

China Phase II in IHCC (NCT04353375) - This is an open-label, single-arm Phase II study to evaluate the efficacy and safety of HMPL-453 in the treatment of patients with advanced IHCC harboring FGFR2 fusions/rearrangements after at least one line of systemic treatment failure or intolerance. Results from 25 patients treated with two different dosing regimens were presented at the ASCO 2023 annual meeting, supporting the choice of the recommended Phase II dose of 300mg oral QD⁷⁸ (ORR of 50%). After consultation with the NMPA, a monotherapy registration trial design was agreed with ORR as primary endpoint, and the first patient was enrolled in March 2023.

Amdizalisib (HMPL-689)

Amdizalisib is a novel, highly selective oral inhibitor targeting the isoform PI3Kδ, a key component in the B-cell receptor signaling pathway. Amdizalisib has been studied in clinical trials with around 500 patients to date. HUTCHMED currently retains all rights to amdizalisib worldwide.

Amdizalisib monotherapy	Indolent NHL⁷⁹, peripheral T-cell lymphomas	China	Ib	Completed; Updated data presented at ICML⁸⁰ 2023	NCT03128164

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 with alignment with China NMPA to support conditional approval. The trial has fully enrolled the follicular lymphoma cohort and the marginal zone lymphoma cohort enrollment is ongoing. In the follicular lymphoma cohort, the primary endpoint of ORR met its pre-specified threshold of demonstrating a clinically meaningful and a significant increase in ORR in this setting. However, in recent discussions with China NMPA, it is clear that a randomized study is required to support registration. In view of the changing regulatory requirement, we are currently evaluating the clinical development plan and regulatory guidance before deciding the regulatory strategy for this indication.

Phase Ib expansion study in relapsed/refractory lymphoma (NCT03128164) - This is an open‑label study to evaluate amdizalisib in relapsed and/or refractory non-Hodgkin lymphoma patients. Updated safety data as well as efficacy data were reported at ICML in June 2023. At median follow-up duration of 22.1 months, median DoR and PFS were not reached for the 26 efficacy evaluable patients in the follicular lymphoma cohort. For the marginal zone lymphoma cohort of 16 efficacy evaluable patients, at median follow-up duration of 20.3 months, median DoR was not reached and median PFS was 26.8 months. Amdizalisib showed an acceptable safety profile and promising anti-tumor activity in relapsed/refractory lymphoma.

HMPL-306

HMPL-306 is a novel dual-inhibitor of IDH1⁸¹ and IDH2 enzymes. IDH1 and IDH2 mutations have been implicated as drivers of certain hematological malignancies, gliomas and solid tumors, particularly among acute myeloid leukemia patients. HUTCHMED currently retains all rights to HMPL-306 worldwide. The table below shows a summary of the clinical studies for HMPL-306.

China Phase I in hematological malignancies (NCT04272957) - This is a two-phase, open-label Phase I study to evaluate the safety, pharmacokinetics, pharmacodynamics and efficacy of HMPL‑306 in patients of relapsed or refractory hematological malignancies harboring IDH1 and/or IDH2 mutations. The dose escalation phase of the study is completed. The first-in-human dose-escalation phase data was presented at EHA Annual Meeting in June 2023 with ORR of 45-50%. Based on the pharmacodynamic, pharmacokinetic and preliminary clinical findings, a recommended Phase II dose was determined for the dose expansion phase of the study. We are planning to initiate a Phase III registration study during the first half of 2024.

HMPL-760

HMPL-760 is an investigational, non-covalent, third-generation BTK inhibitor. It is a highly potent, selective, and reversible inhibitor with long target engagement against BTK, including wild-type and C481S-mutated BTK. China Phase I studies opened in early 2022 will include relapsed or refractory B-cell non-Hodgkin's lymphoma or CLL⁸³ patients with or without a prior regimen containing a BTK inhibitor. HUTCHMED currently retains all rights to HMPL-760 worldwide.

HMPL-760 monotherapy	CLL, SLL⁸⁴, other B-NHL	China	I	Ongoing since Jan 2022; RP2D⁸⁵ determined; dose expansion ongoing	NCT05190068

HMPL-295

HMPL-295 is a novel ERK inhibitor. ERK is a downstream component of the RAS-RAF-MEK-ERK signaling cascade (MAPK⁸⁶ pathway). This is our first of multiple candidates in discovery targeting the MAPK pathway, followed by HMPL-415 targeting SHP2. A China Phase I study was initiated in July 2021 for HMPL-295. 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 up to 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. Safety and efficacy results on 22 patients with advanced solid tumors were reported during ESMO Asia 2023.

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 in combinations. 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) α and disrupts the "do not eat me" signal that cancer cells use to shield themselves from the immune system. In preclinical studies, HMPL‑A83 demonstrated a high affinity for CD47 antigen on tumor cells and strong phagocytosis induction of multiple tumor cells, as well as 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. HUTCHMED currently retains all rights to HMPL-A83 worldwide.

HMPL-415

HMPL-415 is a novel SHP2 allosteric inhibitor. A China Phase I study was initiated in July 2023. HUTCHMED currently retains all rights to HMPL-415 worldwide.

SHP2 is a non-receptor protein tyrosine phosphatase ubiquitously expressed mainly in the cytoplasm of several tissues. SHP2 modulates diverse cell signaling events that control metabolism, cell growth, differentiation, cell migration, transcription and oncogenic transformation. It interacts with diverse molecules in the cell, and regulates key signaling events including RAS/ERK, PI3K/AKT, JAK/STAT and PD-1 pathways downstream of several receptor tyrosine kinases (RTKs) upon stimulation by growth factors and cytokines. This is the second of multiple candidates to have emerged from our discovery research that targets this pathway, the first being HMPL-295. Dysregulation of SHP2 expression or activity causes many developmental diseases, and hematological and solid tumors.

IMG-004 (BTK inhibitor)	Adult healthy volunteers	Global	I	Single ascending dose completed	NCT05349097

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. Phase I study in healthy volunteers demonstrated that up to 600 mg of IMG-007 was safe and well-tolerated, with no reports of pyrexia or chills, which were common adverse events of rocatinlimab, another OX40 antibody treatment. At projected therapeutic dose levels, IMG-007 demonstrated a mean terminal half-life of 31-37 days. The long half-life combined with a potentially improved safety profile supports IMG-007's best-in-class potential as an OX40 targeted therapy.

Two global, proof-of-concept Phase IIa trials are ongoing. One trial evaluates the safety, pharmacokinetics and efficacy (EASI at week 12) of IMG-007 in moderate-to-severe atopic dermatitis. Patients received intravenous IMG-007 three times over four weeks. The first patient was dosed in August 2023 and Inmagene expects interim data readout in the third quarter of 2024. Another trial evaluates the safety of IMG-007 in adults with alopecia areata with SALT score ≥ 50. They will be given three doses over four weeks. First patient was dosed in October 2023 and Inmagene expects interim data readout in the third quarter of 2024.

IMG-004 in immunological diseases - This is a small molecule inhibitor that binds to BTK in a non-covalent, reversible manner. Designed specifically for inflammatory and autoimmune diseases that usually require long-term treatment, IMG-004 is potent, highly selective and brain permeable. A Phase I single ascending dose study in healthy volunteers in the U.S., initiated in August 2022, has recently completed. It showed that IMG‑004 was safe and well-tolerated with a long half-life and sustained pharmacodynamic effects, supporting further clinical development. Results will be submitted to an upcoming medical conference.

MANUFACTURING

We have a drug product manufacturing facility in Suzhou which manufactures both clinical and commercial supplies for fruquintinib and surufatinib. Our Suzhou facility passed a pre-approval inspection (PAI) by the U.S. FDA in August 2023. We have qualified two drug product sites for supplying fruquintinib to the U.S. market: our own facility in Suzhou and a second site in Switzerland.

We have also completed construction of, qualified, and obtained Drug Manufacturing Permit for a new drug product facility in Pudong, Shanghai, which will increase our novel drug product manufacturing capacity by over five times. The manufacturing and technology transfer for some of our commercial products are underway to this new facility. This is in line with our previously outlined expectations of manufacturing clinical supplies from the new facility starting in 2023 and commercial supplies around 2025, after the necessary regulatory filings and approvals.

In line with our commitment to sustainable practices and environmental stewardship, we have installed solar panels at this new facility. They contribute renewable energy directly to our operations, particularly in cooling indoor areas, significantly reducing electricity usage and greenhouse gas emissions.

We completed process validation for the API⁸⁷ and drug product of sovleplenib at the selected commercial manufacturing facilities to support the approval of the product.

OTHER VENTURES

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

In 2023, our Other Ventures delivered growth with consolidated revenue up 18% (24% at CER) to $309.4 million (2022: $262.6m). Consolidated net income attributable to HUTCHMED from our Other Ventures decreased by 8% (3% at CER) to $50.3 million (2022: $54.6m).

Hutchison Sinopharm⁸⁸: 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 24% (31% at CER) to $295.4 million in 2023 (2022: $237.3m).

In 2021, the Hong Kong International Arbitration Centre made a final award in favor of Hutchison Sinopharm against Luye⁸⁹ in the amount of RMB253.2 million ($35.4 million), plus costs and interest (the "Award"), in connection with the termination of Hutchison Sinopharm's right to distribute SEROQUEL^® 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 and subsequent appeals. 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. On June 6, 2023, an appeal hearing filed by Luye was heard by the Court of Appeal in Hong Kong and judgment is awaited.

SHPL: Our own-brand prescription drugs business, operated through our non-consolidated joint venture SHPL, grew sales by 4% (10% at CER) to $385.5 million (2022: $370.6m). Net income attributable to HUTCHMED slightly decreased by 5% (increase 1% at CER) to $47.4 million (2022: $49.9m) mainly due to the impact of gradual price adjustment from volume-based procurement.

The SHPL operation is large-scale, with a commercial team of about 2,300 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 560 manufacturing staff.

SXBX⁹⁰ pill: SHPL's main product is SXBX pill, an oral vasodilator prescription therapy for coronary artery disease. SXBX pill is the second largest botanical prescription drug in this indication in China, with a national market share in January to December 2023 of 22.0% (2022: 21.0%). Sales increased by 2% (8% at CER) to $348.6 million in 2023 (2022: $341.6m).

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 of China.

We continue to explore divestment and equity capital market opportunities to monetize our investment in SHPL.

Dividends: Our share of SHPL's profits are passed to the HUTCHMED Group through dividend payments. In 2023, dividends of $42.3 million (2022: $43.7m) were paid from SHPL to the HUTCHMED Group level with aggregate dividends received by HUTCHMED since inception of over $320 million.

Consumer products businesses disposal: On December 7, 2023, HUTCHMED disposed of its interests in HHOHK and HSN for HK$39.8 million ($5.1 million) to Hutchison Whampoa (China) Limited. The disposal allows HUTCHMED to focus its resources on its core business areas.

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.

Primarily due to an increase in total revenue driven by Oncology/Immunology partnering, its strong commercial progress in China, and growth in third-party distribution sales, we generated a net income attributable to HUTCHMED of $100.8 million for the year ended December 31, 2023 (2022: net loss of $360.8m).

As of December 31, 2023, we had cash and cash equivalents and short-term investments of $886.3 million and unutilized bank facilities of $68.1 million. As of December 31, 2023, we had $79.3 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 approximately $168,000 and $318,000 for the years ended December 31, 2023 and 2022, 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 $1.0 million as of December 31, 2023.

In addition, our non-consolidated joint venture, SHPL, held an aggregate of $19.1 million in cash and cash equivalents and no bank borrowings as of December 31, 2023. 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 generated from/(used in) Operating Activities

Net cash used in operating activities was $268.6 million for the year ended December 31, 2022, compared to net cash generated from operating activities of $219.3 million for the year ended December 31, 2023. The net change of $487.9 million was primarily attributable to the net loss attributable to HUTCHMED of $360.8 million for the year ended December 31, 2022 compared to net income attributable to HUTCHMED of $100.8 million for the year ended December 31, 2023 (which included $312.0 million in upfront and milestone income recognized from Takeda).

Net Cash (used in)/generated from Investing Activities

Net cash generated from investing activities was $296.6 million for the year ended December 31, 2022, compared to net cash used in investing activities of $291.1 million for the year ended December 31, 2023. The net change of $587.7 million was primarily attributable to placement of more short-term investments which had net withdrawals of $316.4 million for the year ended December 31, 2022 as compared to net deposits of $285.0 million for the year ended December 31, 2023. The net change was partially offset by an increase in dividend received from divestment of a former equity investee by $13.0 million from $16.5 million during the year ended December 31, 2022 to $29.5 million during the year ended December 31, 2023.

Net Cash generated from/(used in) Financing Activities

Net cash used in financing activities was $82.8 million for the year ended December 31, 2022, compared to net cash generated from financing activities of $48.7 million for the year ended December 31, 2023. The net change of $131.5 million was mainly attributable to bank borrowings which had a net repayment of $9.2 million during the year ended December 31, 2022 as compared to net proceeds of $61.7 million during the year ended December 31, 2023. The net change was also attributable to a $39.0 million decrease in purchases of ADSs by a trustee for the settlement of equity awards of the Company which totaled $48.1 million for the year ended December 31, 2022 as compared to $9.1 million for the year ended December 31, 2023, as well as a $16.5 million decrease in dividends paid to non-controlling shareholders of subsidiaries from $25.6 million for the year ended December 31, 2022 to $9.1 million for the year ended December 31, 2023.

LOAN FACILITIES

In October 2021, our subsidiary entered into a 10-year fixed asset loan facility agreement with BOC⁹¹ for the provision of a secured credit facility in the amount of RMB754.9 million ($105.5 million) with an annual interest rate at the 5-year China LPR⁹² less 0.8% (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 December 31, 2023, RMB344.8 million ($48.2 million) was utilized from the fixed asset loan facility.

In May 2022, our subsidiary entered into a 12-month revolving loan facility with HSBC⁹³ in the amount of HK$390.0 million ($50.0 million) with an interest rate at HIBOR⁹⁴ plus 0.5% per annum. This revolving facility is guaranteed by us. The revolving loan facility expired in May 2023.

In November 2023, our subsidiary entered into a short-term working capital loan facility with BOC in the amount of RMB300.0 million ($41.9 million) with an annual interest rate at the 1-year China LPR less 0.95%. This credit facility includes certain financial covenant requirements. As of December 31, 2023, RMB222.9 million ($31.1 million) was drawn from the facility.

Our non-consolidated joint venture SHPL had no bank borrowings outstanding as of December 31, 2023.

FOREIGN EXCHANGE RISK

A substantial portion of our revenue and expenses are denominated in renminbi, and our consolidated financial statements are presented in U.S. dollars. While 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, any significant fluctuation in the value of renminbi may adversely affect our cash flows, results of operations and financial condition in the future.

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 PBOC⁹⁵. 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 results of a 1.0% interest rate shift would be a maximum increase/decrease of $0.1 million for the year ended December 31, 2023.

OFF-BALANCE SHEET ARRANGEMENTS

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

CONTINGENT LIABILITIES

Other than as disclosed in note 15 to the full year 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 10.7% as of December 31, 2023, an increase from 2.8% as of December 31, 2022. The increase was primarily attributable to the increase in interest-bearing loans.

SIGNIFICANT INVESTMENTS HELD

Except for our investment in a non-consolidated joint venture SHPL with a carrying value of $48.4 million including details below and those as disclosed in note 11 to the full year financial statements, we did not hold any other significant investments in the equity of any other companies as of December 31, 2023.

FUTURE PLANS FOR MATERIAL INVESTMENTS AND CAPITAL ASSETS

Note 15 discloses our capital commitment as of December 31, 2023. Subsequent to the construction completion of the drug product facility in Shanghai, certain investments in capital assets in relation to the facility will be made.

MATERIAL ACQUISITIONS AND DISPOSALS OF SUBSIDIARIES, ASSOCIATES AND JOINT VENTURES

During the year ended December 31, 2023, 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 BOC is secured by the underlying leasehold land and buildings. RMB344.8 million ($48.2 million) was utilized from the fixed asset loan facility as of December 31, 2023.

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 1.5% and 1.8% in 2021 and 2022 respectively and decreased by 0.3% in 2023. 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.

FINAL DIVIDEND

The Board does not recommend any final dividend for the year ended December 31, 2023.

3. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. When a subsidiary is deconsolidated from the date that control ceases, any gain or loss on the divestment of the interest sold is recognized in profit or loss. Amounts previously recognized in other comprehensive income/(loss) for the subsidiary are transferred to the consolidated statements of operations as part of the gain or loss on the divestment. All inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the U.S. ("U.S. GAAP").

Use of Estimates

The preparation of 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.

Foreign Currency Translation

The Company's presentation currency and functional currency is the U.S. dollar ("US$"). The financial statements of its subsidiaries with a functional currency other than the US$ have been translated into the Company's presentation currency. All assets and liabilities of the subsidiaries are translated using year-end exchange rates and revenue and expenses are translated at average exchange rates for the year. Translation adjustments are reflected in accumulated other comprehensive income/(loss) in shareholders' equity.

Net foreign currency exchange gains/(losses) of US$8,661,000, (US$5,704,000) and US$1,671,000 were recorded in other income and expense in the consolidated statements of operations for the years ended December 31, 2023, 2022 and 2021 respectively.

Foreign Currency Risk

The Group's operating transactions and its assets and liabilities in the PRC are mainly denominated in Renminbi ("RMB"), which is not freely convertible into foreign currencies. The Group's cash and cash equivalents denominated in RMB are subject to government controls. The value of the RMB is subject to fluctuations from central government policy changes and international economic and political developments that affect the supply and demand of RMB in the foreign exchange market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People's Bank of China (the "PBOC"). Remittances in currencies other than RMB by the Group in the PRC must be processed through the PBOC or other PRC foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

Allowance for Current Expected Credit Losses and Concentration of Credit Risk

Financial instruments that potentially expose the Group to credit risk consist primarily of cash and cash equivalents, short-term investments, and financial assets not carried at fair value including accounts receivable and other receivables.

The Group recognizes an allowance for current expected credit losses ("CECLs") on financial assets not carried at fair value. CECLs are calculated over the expected life of the financial assets on an individual or a portfolio basis considering information available about the counterparties' credit situation and collectability of the specific cash flows, including information about past events, current conditions and future forecasts.

The Group places substantially all of its cash and cash equivalents and short-term investments in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any particular financial institution. Additionally, the Group has policies in place to ensure that sales are made to customers with an appropriate credit history and the Group performs periodic credit evaluations of its customers. Normally the Group does not require collateral from trade debtors. The Group has not had any material credit losses.

Cash and Cash Equivalents

The Group considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of cash on hand and bank deposits and are stated at cost, which approximates fair value.

Short-term Investments

Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from customers based on their outstanding invoices. The allowance for CECLs reflects the Group's current estimate of credit losses expected to be incurred over the life of the receivables. The Group considers various factors in establishing, monitoring, and adjusting its allowance for CECLs including the aging of the accounts and aging trends, the historical level of charge-offs, and specific exposures related to particular customers. The Group also monitors other risk factors and forward-looking information, such as country risk, when determining credit limits for customers and establishing adequate allowances for CECLs. Accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads based on normal operating capacity. Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. A provision for excess and obsolete inventory will be made based primarily on forecasts of product demand and production requirements. The excess balance determined by this analysis becomes the basis for excess inventory charge and the written-down value of the inventory becomes its cost. Written-down inventory is not written up if market conditions improve.

Property, Plant and Equipment

Property, plant and equipment consist of buildings, leasehold improvements, plant and equipment, furniture and fixtures, other equipment and motor vehicles. Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets.

Buildings	20 years
Plant and equipment	5-10 years
Furniture and fixtures, other equipment and motor vehicles	4-5 years
Leasehold improvements	Shorter of (a) 5 years or (b) remaining term of lease

Additions and improvements that extend the useful life of an asset are capitalized. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Group evaluates the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. The Group evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If indicators of impairment exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Investments in Equity Investees

Investments in equity investees over which the Group has significant influence are accounted for using the equity method. The Group evaluates equity method investments for impairment when events or circumstances suggest that their carrying amounts may not be recoverable. An impairment charge would be recognized in earnings for a decline in value that is determined to be other-than-temporary after assessing the severity and duration of the impairment and the likelihood of recovery before disposal. The investments are recorded at fair value only if impairment is recognized.

Leasehold Land

Leasehold land represents fees paid to acquire the right to use the land on which various plants and buildings are situated for a specified period of time from the date the respective right was granted and are stated at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the lease period of 50 years.

Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, the Group has the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired. If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value.

Other Intangible Assets

Other intangible assets with finite useful lives are carried at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the estimated useful lives of the assets.

Borrowings

Borrowings are recognized initially at fair value, net of debt issuance costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of debt issuance costs) and the redemption value is recognized in the consolidated statements of operations over the period of the borrowings using the effective interest method.

Ordinary Shares

The Company's ordinary shares are stated at par value of US$0.10 per ordinary share. The difference between the consideration received, net of issuance cost, and the par value is recorded in additional paid-in capital.

The Company's ordinary shares are traded in the form of ordinary shares and ADS. Each ADS represents five ordinary shares.

Treasury Shares

The Group accounts for treasury shares under the cost method. The treasury shares are purchased for the purpose of the LTIP and held by a trustee appointed by the Group (the "Trustee") prior to vesting.

Share-Based Compensation

Share options

The Group recognizes share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the Polynomial model. This Polynomial pricing model uses various inputs to measure fair value, including the market value of the Company's underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rates and expected dividend yields. The Group recognizes share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and accounts for forfeitures as they occur.

Share options are classified as equity-settled awards. Share-based compensation expense, when recognized, is charged to the consolidated statements of operations with the corresponding entry to additional paid-in capital.

LTIP

The Group recognizes the share-based compensation expense on the LTIP awards based on a fixed or determinable monetary amount on a straight-line basis for each annual tranche awarded over the requisite period. For LTIP awards with performance targets, prior to their determination date, the amount of LTIP awards that is expected to vest takes into consideration the achievement of the performance conditions and the extent to which the performance conditions are likely to be met. Performance conditions vary by awards, and may include targets for shareholder returns, financings, revenue, net income after taxes and the achievement of clinical, regulatory, business development and manufacturing milestones.

These LTIP awards are classified as liability-settled awards before the determination date (i.e. the date when the achievement of any performance conditions are known), 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. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management's assessment of the achievement of the performance targets has been assigned to calculate the amount to be recognized as an expense over the requisite period.

After the determination date or if the LTIP awards have no performance conditions, the LTIP awards are classified as equity-settled awards. If the performance target is achieved, the Group will pay the determined monetary amount to the Trustee to purchase ordinary shares of the Company or the equivalent ADS. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital. If the performance target is not achieved, no ordinary shares or ADS of the Company will be purchased and the amount previously recorded in the liability will be reversed and included in the consolidated statements of operations.

Defined Contribution Plans

The Group's subsidiaries in the PRC participate in a government-mandated multi-employer defined contribution plan pursuant to which certain retirement, medical and other welfare benefits are provided to employees. The relevant labor regulations require the Group's subsidiaries in the PRC to pay the local labor and social welfare authority's monthly contributions at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor and social welfare authorities are responsible for meeting all retirement benefits obligations and the Group's subsidiaries in the PRC have no further commitments beyond their monthly contributions. The contributions to the plan are expensed as incurred.

The Group also makes payments to other defined contribution plans for the benefit of employees employed by subsidiaries outside the PRC. The defined contribution plans are generally funded by the relevant companies and by payments from employees.

The Group's contributions to defined contribution plans for the years ended December 31, 2023, 2022 and 2021 were US$11,708,000, US$11,795,000 and US$7,181,000 respectively.

Revenue Recognition

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good, service or license to a customer.

(i) Goods and services

The Group principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of pharmaceutical products and other consumer health products, and (2) provision of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. The Group evaluates whether it is the principal or agent for these contracts. Where the Group obtains control of the goods for distribution, it is the principal (i.e. recognizes sales of goods on a gross basis). Where the Group does not obtain control of the goods for distribution, it is the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenue is recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Deferred revenue is recognized if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

(ii) License and collaboration contracts

The Group's Oncology/Immunology reportable segment includes revenue generated from license and collaboration contracts, which generally contain multiple performance obligations including (1) the licenses to the development, commercialization and manufacture rights of a drug compound, (2) the research and development services for each specified treatment indication, and (3) other deliverables, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. The Group estimates the standalone selling prices based on the income approach and cost plus margin approach. Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using a percentage-of-completion method. The Group has determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment. Royalty revenue is recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

Deferred revenue is recognized if allocated consideration is received in advance of the Group rendering research and development services or earning royalties on future sales. Accounts receivable is recognized based on the terms of the contract and when the Group has an unconditional right to bill the customer, which is generally when research and development services are rendered.

Research and Development Expenses

Research and development expenses include the following: (i) research and development costs, which are expensed as incurred; (ii) acquired in-process research and development ("IPR&D") expenses, which include the initial costs of externally developed IPR&D projects, acquired directly in a transaction other than a business combination, that do not have an alternative future use; and (iii) milestone payment obligations for externally developed IPR&D projects incurred prior to regulatory approval of the product in the in-licensed territory, which are accrued when the event requiring payment of the milestone occurs (milestone payment obligations incurred upon regulatory approval are recorded as other intangible assets).

Collaborative Arrangements

The Group enters into collaborative arrangements with collaboration partners that fall under the scope of Accounting Standards Codification ("ASC") 808, Collaborative Arrangements ("ASC 808"). The Group records all expenditures for such collaborative arrangements in research and development expenses as incurred, including payments to third party vendors and reimbursements to collaboration partners, if any. Reimbursements from collaboration partners are recorded as reductions to research and development expenses and accrued when they can be contractually claimed.

Government Grants

Grants from governments are recognized at their fair values. Government grants that are received in advance are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate. Government grants in relation to the achievement of stages of research and development projects are recognized in the consolidated statements of operations when amounts have been received and all attached conditions have been met. Non-refundable grants received without any further obligations or conditions attached are recognized immediately in the consolidated statements of operations.

Leases

In an operating lease, a lessee obtains control of only the use of the underlying asset, but not the underlying asset itself. An operating lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments that depend on an index or a rate; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee's incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the operating lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the operating lease, the Group recognizes lease expenses on a straight-line basis over the lease term. The right-of-use asset is subsequently measured at cost less accumulated amortization and any impairment provision. The amortization of the right-of-use asset represents the difference between the straight-line lease expense and the accretion of interest on the lease liability each period. The interest amount is used to accrete the lease liability and to amortize the right-of-use asset. There is no amount recorded as interest expense.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Subleases of right-of-use assets are accounted for similar to other leases. As an intermediate lessor, the Group separately accounts for the head-lease and sublease unless it is relieved of its primary obligation under the head-lease. Sublease income is recorded on a gross basis separate from the head-lease expenses. If the total remaining lease cost on the head-lease is more than the anticipated sublease income for the lease term, this is an indicator that the carrying amount of the right-of-use asset associated with the head-lease may not be recoverable, and the right-of-use asset will be assessed for impairment.

Income Taxes

The Group accounts for income taxes under the liability method. Under the liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the income tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the net deferred income tax asset will not be realized.

The Group accounts for an uncertain tax position in the consolidated financial statements only if it is more likely than not that the position is sustainable based on its technical merits and consideration of the relevant tax authority's widely understood administrative practices and precedents. If the recognition threshold is met, the Group records the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement.

The Group recognizes interest and penalties for income taxes, if any, under income tax payable on its consolidated balance sheets and under other expense in its consolidated statements of operations.

Earnings/(losses) per Share

Basic earnings/(losses) per share is computed by dividing net income/(loss) attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Weighted average number of outstanding ordinary shares in issue excludes treasury shares.

Diluted earnings/(losses) per share is computed by dividing net income/(loss) attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include ordinary shares and treasury shares issuable upon the exercise or settlement of share-based awards or warrants issued by the Company using the treasury stock method. The computation of diluted earnings/(losses) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect.

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief executive officer who is the Group's chief operating decision maker. The chief operating decision maker reviews the Group's internal reporting in order to assess performance and allocate resources.

Profit Appropriation and Statutory Reserves

The Group's subsidiaries and equity investee established in the PRC are required to make appropriations to certain non-distributable reserve funds.

In accordance with the relevant laws and regulations established in the PRC, the Company's subsidiaries registered as wholly-owned foreign enterprise have to make appropriations from their after-tax profits (as determined under generally accepted accounting principles in the PRC ("PRC GAAP")) to reserve funds including general reserve fund, enterprise expansion fund and staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the company. Appropriations to the enterprise expansion fund and staff bonus and welfare fund are made at the respective company's discretion. For the Group's equity investee, the amount of appropriations to these funds are made at the discretion of its respective board.

In addition, Chinese domestic companies must make appropriations from their after-tax profits as determined under PRC GAAP to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10% of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the company. Appropriation to the discretionary surplus fund is made at the respective company's discretion.

The use of the general reserve fund, enterprise expansion fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increases to the registered capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to employees and for the collective welfare of employees. All these reserves are not permitted to be transferred to the company as cash dividends, loans or advances, nor can they be distributed except under liquidation.

4. Fair Value Disclosures

Cash equivalents, short-term investments, accounts receivable, other receivables, accounts payable and other payables are carried at cost, which approximates fair value due to the short-term nature of these financial instruments. Bank borrowings are floating rate instruments and carried at amortized cost, which approximates fair values.

17. Share-based Compensation

(i) Share‑based Compensation of the Company

The Company conditionally adopted a share option scheme 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 December 31, 2023, the aggregate number of shares issuable under the Hutchmed Share Option Scheme was 42,161,098 ordinary shares. The Company will issue new shares to satisfy share option exercises. Additionally, the number of shares authorized but unissued was 628,743,730 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 ten years from the date of grant.

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

	Number of share options	Weighted average exercise price in US$ per share	Weighted average remaining contractual life (years)	Aggregate intrinsic value (in US$'000)
Outstanding at January 1, 2022	37,190,590	4.88	7.04	82,377
Granted (note)	7,680,820	2.26

Cancelled	(2,832,340)	4.61
Expired	(1,893,370)	5.55
Outstanding at December 31, 2023	29,536,655	4.57	6.67	9,924
Vested and exercisable at December 31, 2022	21,113,285	4.57	4.80	6,288
Vested and exercisable at December 31, 2023	18,198,170	5.10	5.91	1,753

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 if the performance target based on a market condition is met.

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:

	Year Ended December 31,
	2023	2022
Weighted average grant date fair value of share options (in US$ per share)	1.14	0.85
Significant inputs into the valuation model (weighted average):
Exercise price (in US$ per share)	2.50	2.26
Share price at effective date of grant (in US$ per share)	2.50	2.22
Expected volatility (note (a))	53.3%	46.7%
Risk-free interest rate (note (b))	3.69%	2.98%
Contractual life of share options (in years)	10	10
Expected dividend yield (note (c))	0%	0%

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:

	Year Ended December 31,
	2023	2022	2021
	(in US$'000)
Cash received from share option exercises	5,094	174	2,452
Total intrinsic value of share option exercises	4,626	92	2,999

The Group recognizes compensation expense on a graded vesting approach over the requisite service period. The following table presents share-based compensation expense included in the Group's consolidated statements of operations:

	Year Ended December 31,
	2023	2022	2021
	(in US$'000)
Research and development expenses	3,250	4,803	8,460
Selling and administrative expenses	2,843	1,803	7,783
Cost of revenue	91	130	122
	6,184	6,736	16,365

As at December 31, 2023, the total unrecognized compensation cost was US$5,057,000, and will be recognized on a graded vesting approach over the weighted average remaining service period of 2.15 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, revenue, net income/(loss) after taxes and the achievement of clinical, regulatory, business development and manufacturing 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. Based on the actual achievement of performance target, the amount previously recorded in the liability will be adjusted through share-based compensation expense.

Granted awards under the LTIP are as follows:

	Maximum cash amount	Covered	Performance target
Grant date	(in US$ millions)	financial years	determination date
May 23, 2022	60.4	2022	note (a)
September 13, 2022	3.8	2022	note (a)
September 13, 2022	1.7	note (b)	note (b)
June 5, 2023	54.9	2023	note (a)

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.

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 ordinary shares equivalent) held by the Trustee were as follows:

	Number of treasury shares	Cost (in US$'000)
As at January 1, 2022	8,139,175	40,014
Purchased	14,028,465	48,084
Vested	(2,566,265)	(12,034)
As at December 31, 2022	19,601,375	76,064

Vested	(4,714,205)	(18,148)
As at December 31, 2023	17,612,685	66,987

Based on the estimated achievement of performance conditions for 2023 financial year LTIP awards, the determined monetary amount was US$50,262,000 which is recognized to share-based compensation expense over the requisite vesting period to March 2026.

For the years ended December 31, 2023 and 2022, US$7,332,000 and US$19,031,000 of the LTIP awards were forfeited respectively based on the determined or estimated monetary amount as at the forfeiture date.

As at December 31, 2023 and 2022, US$10,502,000 and US$3,701,000 were recorded as liabilities respectively for LTIP awards prior to the determination date.

As at December 31, 2023, the total unrecognized compensation cost was approximately US$50,447,000, which considers expected performance targets and the amounts expected to vest, and will be recognized over the requisite periods.

License and collaboration agreement with Takeda Pharmaceuticals

On January 23, 2023, the Group and Takeda Pharmaceuticals International AG ("Takeda") entered into an exclusive out-licensing agreement (the "Takeda Agreement") in territories outside of Mainland China, Hong Kong and Macau (the "Territory") to further the global development, commercialization and manufacturing of Fruzaqla, also known as fruquintinib, a targeted oncology therapy for the treatment of various types of solid tumors. Under the terms of the Takeda Agreement, the Group is entitled to receive a series of payments up to US$1.13 billion, including upfront, regulatory, development and commercial sales milestone payments, plus royalties on net sales in the Territory. Fruzaqla was successfully approved for commercialization in the U.S. in November 2023, which triggered a regulatory approval milestone of US$35 million.

Upfront and milestone payments according to the Takeda Agreement received up to December 31, 2023 are summarized as follows:

	(in US$'000)
Upfront payment	400,000
Regulatory approval milestone payment achieved	35,000

As of December 31, 2023, the total revenue recognized under the Takeda Agreement is US$353.1 million, which included US$280.0 million of the upfront payment and US$32.0 million of the regulatory approval milestone payment received.

The Takeda Agreement has the following material performance obligations: (1) the licenses for the development and commercialization of Fruzaqla in the Territory and the manufacture of Fruzaqla for use in the Territory, (2) manufacturing supply and (3) services for research and development including ongoing clinical trials and regulatory submissions and manufacturing technology transfer.

The transaction price for these performance obligations includes the upfront payment, service cost reimbursements, milestone payments and sales-based royalties. Milestone payments are not included in the transaction price until they become probable that a significant reversal of revenue would not occur, which is generally when the criteria to receive the specified milestone are achieved.

The allocation of the transaction price to each relevant performance obligation was based on the relative standalone selling price of each performance obligation determined at the inception of the contract. Variable consideration is allocated entirely to a performance obligation or to a distinct good or service that forms part of a single performance obligation if the terms of the variable consideration relate to the satisfaction of the respective performance obligation and the amount allocated is consistent with the amount expected to be received for the satisfaction of the respective performance obligation. The standalone selling price of the licenses for the development and commercialization of Fruzaqla in the Territory and the manufacture of Fruzaqla for use in the Territory and manufacturing supply was determined using a discounted cash flow method based on the probability-weighted present value of forecasted cash flows associated with out-licensing Fruzaqla in the Territory, and the standalone selling price of the services for research and development of ongoing clinical trials, regulatory submissions and manufacturing technology transfer was determined using a cost plus margin approach based on the present value of estimated future service costs plus a reasonable margin. Significant assumptions included in the determination of the standalone selling prices for each performance obligation identified including forecasted revenue, probabilities of regulatory approvals, estimated future service costs, margin rates and discount rates. Based on these estimations, proportionate amounts of transaction price to be allocated to the licenses, and other performance obligations were 62% and 38% respectively at contract inception. Control of the licenses to Fruzaqla was transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Manufacturing supply is recognized at a point in time when the control of the goods is transferred. Services are performed over the term of the Takeda Agreement and amounts allocated are recognized over time using a percentage-of-completion method. Royalties are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

Revenue recognized under the Takeda Agreement is as follows:

	Year Ended December 31, 2023
	(in US$'000)
Manufacturing supply-Invoiced Marketed Products sales	5,053
-Allocated from upfront payment	4,718
Services-Research and Development	33,892

License and collaboration agreement with Eli Lilly

On October 8, 2013, the Group entered into a licensing, co-development and commercialization agreement in China with Eli Lilly and Company ("Lilly") relating to Elunate ("Lilly Agreement"), as the China brand name for fruquintinib. Under the terms of the Lilly Agreement, the Group is entitled to receive a series of payments up to US$86.5 million, including upfront payments and development and regulatory approval milestones. Development costs after the first development milestone are shared between the Group and Lilly. Elunate was successfully commercialized in China in November 2018, and the Group receives tiered royalties in the range of 15% to 20% on all sales in China.

In December 2018, the Group entered into various amendments to the Lilly Agreement (the "2018 Amendment"). Under the terms of the 2018 Amendment, the Group is entitled to determine and conduct future life cycle indications ("LCI") development of Elunate in China beyond the three initial indications specified in the Lilly Agreement and will be responsible for all associated development costs. In return, the Group will receive additional regulatory approval milestones of US$20 million for each LCI approved, for up to three LCI or US$60 million in aggregate, and will increase tiered royalties to a range of 15% to 29% on all Elunate sales in China upon the commercial launch of the first LCI. Additionally, through the 2018 Amendment, Lilly has provided consent, and freedom to operate, for the Group to enter into joint development collaborations with certain third-party pharmaceutical companies to explore combination treatments of Elunate and various immunotherapy agents. The 2018 Amendment also provided the Group rights to promote Elunate in provinces that represent 30% to 40% of the sales of Elunate in China upon the occurrence of certain commercial milestones by Lilly. Such rights were further amended below.

In July 2020, the Group entered into an amendment to the Lilly Agreement (the "2020 Amendment") relating to the expansion of the Group's role in the commercialization of Elunate across all of China. Under the terms of the 2020 Amendment, the Group is responsible for providing promotion and marketing services, including the development and execution of all on-the-ground medical detailing, promotion and local and regional marketing activities, in return for service fees on sales of Elunate made by Lilly. In October 2020, the Group commenced such promotion and marketing services. In addition, development and regulatory approval milestones for an initial indication under the Lilly Agreement were increased by US$10 million in lieu of cost reimbursement.

Upfront and cumulative milestone payments according to the Lilly Agreement received up to December 31, 2023 are summarized as follows:

		(in US$'000)
Upfront payment		6,500
Development milestone payments achieved		40,000

The Lilly Agreement has the following performance obligations: (1) the license for the commercialization rights to Elunate and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to Elunate and the research and development services were 90% and 10% respectively. Control of the license to Elunate transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using a percentage-of-completion method. Royalties are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

The 2018 Amendment is a separate contract as it added distinct research and development services for the LCIs to the Lilly Agreement. The 2020 Amendment related to the promotion and marketing services is a separate contract as it added distinct services to the Lilly Agreement. Such promotion and marketing services are recognized over time based on amounts that can be invoiced to Lilly. The 2020 Amendment related to the additional development and regulatory approval milestone amounts is a modification as it only affected the transaction price of research and development services for a specific indication under the Lilly Agreement, and therefore, such additional milestone amounts will be included in the transaction price accounted under the Lilly Agreement once the specified milestones are achieved.

Revenue recognized under the Lilly Agreement and subsequent amendments is as follows:

	Year Ended December 31,

License and collaboration agreement with AstraZeneca

On December 21, 2011, the Group and AstraZeneca AB (publ) ("AZ") entered into a global licensing, co-development, and commercialization agreement for Orpathys ("AZ Agreement"), also known as savolitinib, a novel targeted therapy and a highly selective inhibitor of the c-Met receptor tyrosine kinase for the treatment of cancer. Under the terms of the AZ Agreement, the Group is entitled to receive a series of payments up to US$140 million, including upfront payments and development and first-sale milestones. Additionally, the AZ Agreement contains possible significant future commercial sale milestones. Development costs for Orpathys in China will be shared between the Group and AZ, with the Group continuing to lead the development in China. AZ will lead and pay for the development of Orpathys for the rest of the world. Orpathys was successfully commercialized in China in July 2021, and the Group receives fixed royalties of 30% based on all sales in China. Should Orpathys be successfully commercialized outside China, the Group would receive tiered royalties from 9% to 13% on all sales outside of China.

In August 2016 (as amended in December 2020), the Group entered into an amendment to the AZ Agreement whereby the Group shall pay the first approximately US$50 million of phase III clinical trial costs related to developing Orpathys for renal cell carcinoma ("RCC"), and remaining costs will be shared between the Group and AZ. Subject to approval of Orpathys in RCC, the Group would receive additional tiered royalties on all sales outside of China, with the incremental royalty rates determined based on actual sharing of development costs. In November 2021, the Group entered into an additional amendment which revised the sharing between the Group and AZ of development costs for Orpathys in China for non-small cell lung cancer, as well as adding potential development milestones.

Upfront and cumulative milestone payments according to the AZ Agreement received up to December 31, 2023 are summarized as follows:

	(in US$'000)
Upfront payment	20,000
Development milestone payments achieved	40,000
First-sale milestone payment achieved	25,000

The AZ Agreement has the following performance obligations: (1) the license for the commercialization rights to Orpathys and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to Orpathys and the research and development services were 95% and 5% respectively. Control of the license to Orpathys transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using a percentage-of-completion method.

Revenue recognized under the AZ Agreement and subsequent amendments is as follows:

19. 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 is 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 (which occurred in 2023), the Group will incur tiered royalties based on net sales. For the year ended December 31, 2023, the Group incurred royalties of US$9,000.

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 IPR&D. During the year ended December 31, 2022, US$5.0 million development milestone was paid and expensed to research and development expenses as IPR&D.

The warrant was recorded as a financial asset at fair value with changes to fair value recognized to the consolidated statements of operations. During the year ended December 31, 2022, an affiliate of Ipsen S.A. acquired all outstanding shares of Epizyme and the warrant expired under the terms of the In-license Agreement and warrant. For the years ended December 31, 2022 and 2021, fair value losses of US$2.5 million and US$12.5 million were recognized to other expense in the consolidated statements of operations respectively.

Under the Hong Kong two-tiered profits tax rates regime, the first HK$2.0 million (US$0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong profits tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

(b) Taxation in the PRC has been provided for at the applicable rate on the estimated assessable profits less estimated available tax losses, if any, in each entity. Under the PRC Enterprise Income Tax Law (the "EIT Law"), the standard enterprise income tax rate is 25%. In addition, the EIT Law provides for a preferential tax rate of 15% for companies which qualify as HNTE. HUTCHMED Limited and its wholly-owned subsidiary HUTCHMED (Suzhou) Limited qualify as a HNTE up to December 31, 2025 and 2023 respectively.

Pursuant to the EIT law, a 10% withholding tax is levied on dividends paid by PRC companies to their foreign investors. A lower withholding tax rate of 5% is applicable under the China-HK Tax Arrangement if direct foreign investors with at least 25% equity interest in the PRC companies are Hong Kong tax residents, and meet the conditions or requirements pursuant to the relevant PRC tax regulations regarding beneficial ownership. Since the equity holders of the equity investees of the Company are Hong Kong incorporated companies and Hong Kong tax residents, and meet the aforesaid conditions or requirements, the Company has used 5% to provide for deferred tax liabilities on retained earnings which are anticipated to be distributed. As at December 31, 2023, 2022 and 2021, the amounts accrued in deferred tax liabilities relating to withholding tax on dividends were determined on the basis that 100% of the distributable reserves of the equity investees operating in the PRC will be distributed as dividends.

Pursuant to PRC Bulletin on Issues of Enterprise Income Tax and Indirect Transfers of Assets by Non-PRC Resident Enterprises, an indirect transfer of a PRC resident enterprise by a non-PRC resident enterprise, via the transfer of an offshore intermediate holding company, shall be subject to PRC withholding tax under certain conditions.

(c) Current tax in the PRC for the year ended December 31, 2021 includes US$14.4 million arising from the indirect disposal of HBYS (Note 22), calculated at 10% of the excess of the disposal proceeds over the cost of acquiring the equity investment in HBYS.

(d) The Company's subsidiary in the U.S. with operations primarily in New Jersey is subject to U.S. taxes, primarily federal and state taxes, which have been provided for at approximately 21% (federal) and 0% to 11.5% (state tax) on the estimated assessable profit over the reporting years. Certain income receivable by the Company is subject to U.S. withholding tax of 30%. Two of the Group's subsidiaries are subject to corporate tax in the UK and EU countries at 19% and 15% to 25%, respectively, on the estimated assessable profits in relation to their presence in these countries.

The reconciliation of the Group's reported income tax expense to the theoretical tax amount that would arise using the tax rates of the Company against the Group's income/(loss) before income taxes and equity in earnings of equity investees is as follows:

	Year Ended December 31,
	2023	2022	2021
		(in US$'000)
Income/(loss) before income taxes and equity in earnings of equity investees	58,308	(410,422)	(215,740)

(ii) Deferred tax assets and liabilities

The significant components of deferred tax assets and liabilities are as follows:

	December 31,
	2023	2022
	(in US$'000)
Deferred tax assets
Cumulative tax losses	284,271	264,751

Deferred tax liabilities
Undistributed earnings from a PRC entity	1,478	2,686
Others	6	24
Deferred tax liabilities	1,484	2,710

The movements in deferred tax assets and liabilities are as follows:

	2023	2022	2021
	(in US$'000)
As at January 1	12,656	6,636	(3,548)
Movement of previously recognized withholding tax on undistributed earnings	3,674	2,186	5,148
(Charged)/Credited to the consolidated statements of operations

Reclassification from current tax	11	-	-
Divestment of subsidiaries	(49)	-	-
Divestment of an equity investee	-	-	370
Exchange differences	(95)	271	(52)
As at December 31	13,972	12,656	6,636

The deferred tax assets and liabilities are offset when there is a legally enforceable right to set off and when the deferred income taxes relate to the same fiscal authority.

The cumulative tax losses can be carried forward against future taxable income and will expire in the following years:

	December 31,
	2023	2022
	(in US$'000)
No expiry date	74,515	71,325
2024	3,529	3,763
2025	35,030	36,098
2026	46,766	48,150
2027	60,033	61,808
2028	103,913	107,297
2029	171,142	175,853
2030	237,384	243,918
2031	379,321	389,761
2032	594,311	610,800
2033	176,363	-
	1,882,307	1,748,773

The Company believes that it is more likely than not that future operations outside the U.S. will not generate sufficient taxable income to realize the benefit of the deferred tax assets. Certain of the Company's subsidiaries have had sustained tax losses, which will expire within five years if not utilized in the case of PRC subsidiaries (ten years for HNTEs), and which will not be utilized in the case of Hong Kong subsidiaries as they do not generate taxable profits. Accordingly, a valuation allowance has been recorded against the relevant deferred tax assets arising from the tax losses.

A U.S. subsidiary of the Company has approximately US$4.7 million and US$1.1 million U.S. Federal and New Jersey state research tax credits which will expire between 2041 and 2043 (Federal) and 2028 and 2030 (New Jersey) respectively, if not utilized.

The table below summarizes changes in the deferred tax valuation allowance:

	2023	2022	2021
	(in US$'000)
As at January 1	264,639	189,700	122,378
Charged to consolidated statements of operations	26,629	93,243	63,975

Exchange differences	(7,162)	(18,178)	3,542
As at December 31	283,522	264,639	189,700

As at December 31, 2023, 2022 and 2021, the Group did not have any material unrecognized uncertain tax positions.

26. Earnings/(Losses) Per Share

(i) Basic earnings/(losses) per share

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

	Year Ended December 31,
	2023	2022	2021
Weighted average number of outstanding ordinary shares in issue	849,654,296	847,143,540	792,684,524
Net income/(loss) attributable to the Company (US$'000)	100,780	(360,835)	(194,648)
Basic earnings/(losses) per share attributable to the Company (US$ per share)	0.12	(0.43)	(0.25)

(ii) Diluted earnings/(losses) per share

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

	Year Ended December 31,
	2023	2022	2021
Weighted average number of outstanding ordinary shares in issue	849,654,296	847,143,540	792,684,524
Effect of share options and LTIP awards	19,542,052	-	-
Weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding	869,196,348	847,143,540	792,684,524
Net income/(loss) attributable to the Company (US$'000)	100,780	(360,835)	(194,648)
Diluted earnings/(losses) per share attributable to the Company (US$ per share)	0.12	(0.43)	(0.25)

For the years ended December 31, 2022 and 2021, the share options, LTIP awards and warrants issued by the Company were not included in the calculation of diluted losses per share because of their anti-dilutive effect.

27. Segment Reporting

The Group's operating segments are as follows:

(i) Oncology/Immunology: focuses on discovering, developing, and commercializing targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. Oncology/Immunology is further segregated into two core business areas:

29. 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 financial position, results of operations 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, results of operations or cash flows 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$35.4 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 and subsequent appeals. 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. On October 7, 2022, Luye filed a Notice of Appeal to the Court of Appeal regarding the dismissal and the notice was accepted on November 8, 2022. On June 6, 2023, a Court of Appeal hearing was held and a judgment is expected but yet to be received. The legal proceedings are ongoing and as no Award amounts have been received as at the issuance date of these consolidated financial statements, no Award amounts have been recognized and no adjustment has been made to Seroquel-related balances as at December 31, 2023. Such Seroquel-related balances include accounts receivable, long-term prepayment, accounts payable and other payables of US$1.1 million, US$0.2 million, US$0.9 million and US$1.1 million respectively.

30. Restricted Net Assets

Relevant PRC laws and regulations permit payments of dividends by the Company's subsidiaries in the PRC only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company's subsidiaries in the PRC are required to make certain appropriations of net after-tax profits or increases in net assets to the statutory surplus fund prior to payment of any dividends. In addition, registered share capital and capital reserve accounts are restricted from withdrawal in the PRC, up to the amount of net assets held in each subsidiary. As a result of these and other restrictions under PRC laws and regulations, the Company's subsidiaries in the PRC are restricted in their ability to transfer their net assets to the Group in terms of cash dividends, loans or advances, with restricted portions amounting to US$1.0 million and US$0.1 million as at December 31, 2023 and 2022 respectively, which excludes the Company's subsidiaries with a shareholders' deficit. Even though the Group currently does not require any such dividends, loans or advances from the PRC subsidiaries, for working capital and other funding purposes, the Group may in the future require additional cash resources from the Company's subsidiaries in the PRC due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders.

In addition, the Group has an equity investee in the PRC, where the Group's equity in undistributed earnings amounted to US$29.6 million and US$53.7 million as at December 31, 2023 and 2022 respectively.

31. Subsequent Events

The Group evaluated subsequent events through February 28, 2024, which is the date when the consolidated financial statements were issued.

In February 2024, pursuant to the strategic partnership with Inmagene Biopharmaceuticals ("Inmagene"), Inmagene has exercised its options to license two drug candidates discovered by HUTCHMED, IMG-007 and IMG-004, for approximately 7.5% of shares (fully diluted) in Inmagene, subject to customary closing conditions.

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 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) Tax effects of intercompany unrealized profit

Under U.S. GAAP, deferred taxes for unrealized profit resulting from intercompany sales of inventory is not recognized.

Under IFRS, deferred taxes for unrealized profit resulting from an intercompany sale of inventory is recognized at the buyer's tax rate.

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 IPR&D 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.

(d) 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.

(e) 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 SPA 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 consolidated statement of operations between gain on divestment of an equity investee, equity earnings of equity investees, net of tax and income tax expense.

(f) 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.
