**Sagimet Biosciences Reports Third Quarter 2025 Financial Results and <br> Provides Corporate Updates**

*Phase 1 clinical trial to evaluate the PK of a combination of denifanstat and resmetirom ongoing with <br> data readout expected 1H 2026*

*First-in-human Phase 1 clinical trial of FASN inhibitor TVB-3567 ongoing*

*Ascletis announced completion of its pre-NDA consultation with China's NMPA and plans to submit an <br> NDA for denifanstat in China for treatment of moderate-to-severe acne vulgaris*

**San Mateo, Calif., November 13, 2025** – Sagimet Biosciences Inc. (Sagimet, Nasdaq: SGMT), a clinical-stage biopharmaceutical company developing novel therapeutics targeting dysfunctional metabolic and fibrotic pathways, today reported financial results for the quarter ended September 30, 2025, and provided recent corporate updates.

"This is a dynamic period for Sagimet as we explore the therapeutic potential of FASN inhibition across different indications," said David Happel, Chief Executive Officer of Sagimet. "As part of our MASH development program targeting cirrhosis of the liver, we have initiated a Phase 1 PK trial evaluating the compatibility of a once-daily combination of denifanstat and resmetirom. We plan to use this data, if positive, to advance the combination to proof-of-concept studies in MASH patients with F4 fibrosis. Additionally, we initiated a Phase 1 clinical trial of our second FASN inhibitor, TVB-3567, for development of an acne indication. We continue to explore how FASN inhibition could benefit patients living with conditions that are currently underserved by approved therapies," he concluded.

**Recent Corporate Highlights**

· In September 2025, Sagimet dosed the first participants in a Phase 1 pharmacokinetic (PK) trial of a combination of its oral
once-daily fatty acid synthase (FASN) inhibitor, denifanstat, and a thyroid hormone receptor beta (THR-β) agonist, resmetirom.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o The Phase 1 PK trial of denifanstat and resmetirom is an open-label, 2-cohort study and has enrolled approximately 40 healthy adult
participants. The objectives are to evaluate multiple-dose and single-dose pharmacokinetics, identify any potential drug-drug interactions
(DDI), and assess the safety and tolerability of the combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Topline data from this trial are anticipated in the first half of 2026 and, if positive, may be used to advance the development of
the combination for patients living with metabolic dysfunction associated steatohepatitis (MASH) into a Phase 2 clinical trial, subject
to consultation with regulatory authorities.

· In October 2025, Ascletis Pharma Inc., the parent company of Sagimet's license partner for China, Ascletis Bioscience
Co. Ltd. (Ascletis), announced that it completed its pre-New Drug Application (NDA) consultation with the China National Medical
Products Administration (NMPA) for denifanstat for the treatment of moderate-to-severe acne vulgaris and plans to submit an NDA soon
to the NMPA.

· Effective November 1, Marie O'Farrell, Ph.D., was promoted to Chief Scientific Officer and Liz Rozek, J.D., was promoted
to Chief Legal & Administrative Officer.

**Publications and Presentations**

· In November 2025, Sagimet presented two posters at the American Association for the Study of Liver Disease (AASLD) - The
Liver Meeting<sup>®</sup> 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o In a secondary analysis of the denifanstat phase 2b FASCINATE-2 clinical trial, denifanstat elicited a significant ≥2-stage
improvement in fibrosis in F3 MASH patients, and improved liver fibrosis and several noninvasive biomarkers in a subpopulation
of qFibrosis stage 4 MASH patients identified by AI-based digital pathology (here).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o An analysis utilizing spatial computational histology relying on baseline fibrosis features was used to predict response to denifanstat
(here).

· In October 2025, Sagimet presented the data from Ascletis' Phase 3 clinical trial for the treatment of moderate to severe
acne vulgaris in China at the 2025 Fall Clinical Dermatology Conference (here). As reported by Ascletis, in the clinical trial of
480 patients, once daily 50 mg denifanstat met all efficacy endpoints and was generally well-tolerated.

· In September 2025, Ascletis presented Phase 3 clinical trial data in acne at the European Academy of Dermatology and Venerology (EADV)
2025 Congress (here).

**Anticipated Upcoming Milestones**

· Sagimet anticipates the data read out of its Phase 1 clinical trial to evaluate the PK and tolerability of a combination of denifanstat
and resmetirom in the first half of 2026.

· Subject to consultation with regulatory authorities, Sagimet anticipates starting a Phase 2 clinical trial in moderate to severe acne
patients in 2026 following its ongoing Phase 1 clinical trial of TVB-3567 for development of an acne indication.

**Financial Results for the Three and Nine Months Ended September 30, 2025**

· **Cash, cash equivalents and marketable securities** as of September 30, 2025 were $125.5 million.

· **Research and development expense** for the three and nine months ended September 30, 2025, was $9.7 million and $32.3
million, respectively, compared to $12.7 million and $24.2 million for the three and nine months ended September 30,
2024, respectively.

· **General and administrative expense** for the three and nine months ended September 30, 2025 was $4.6 million and $13.8
million, respectively, compared to $4.2 million and $12.0 million for the three and nine months ended September 30,
2024, respectively.

· **Net loss** for the three and nine months ended September 30, 2025 was $12.9 million and $41.5 million,
respectively, compared to $14.6 million and $29.4 million for the three and nine months ended September 30, 2024,
respectively.

**About Sagimet Biosciences**

Sagimet is a clinical-stage biopharmaceutical company developing novel FASN inhibitors designed to target dysfunctional metabolic and fibrotic pathways in conditions resulting from the overproduction of the fatty acid, palmitate. Denifanstat, an oral, once-daily pill, met all primary endpoints in its Phase 2b FASCINATE-2 clinical trial in MASH as well as all primary and secondary endpoints in Sagimet's license partner for China's Phase 3 clinical trial in moderate-to-severe acne. A combination of denifanstat and resmetirom is currently being tested in a Phase 1 PK clinical trial and is planned to be developed for cirrhotic patients living with F4-stage MASH. TVB-3567, a second oral FASN inhibitor which is planned to be developed for acne, is currently being tested in a Phase 1 first-in-human clinical trial. For additional information about Sagimet, please visit www.sagimet.com.

**About MASH**

MASH is a progressive and severe liver disease which is estimated to impact more than 265 million people worldwide. MASH is characterized by the build-up of fat in the liver and various degrees of inflammation and fibrosis along with systemic metabolic changes including dyslipidemia (increased fat levels in blood) and insulin resistance. Patients with moderate to severe disease who have advanced fibrosis (F3) or cirrhosis (F4) have the highest risk of liver-related outcomes such as decompensation, hepatocellular carcinoma, and liver transplantation. There are few approved treatments for non-cirrhotic MASH (stages F1, F2 and F3 fibrosis) and no approved treatments for MASH cirrhosis (F4).

**About Acne**

There are 5.1 million acne patients treated by dermatologists annually in the U.S., and a total U.S. acne market of over 50 million people.<sup>1,2</sup> There is no cure for acne; and due to its pathology, most patients require chronic management and multiple courses of treatment for flare control annually. Additionally, adherence to topical therapies is lower than with oral agents, with an estimated 30% to 40% of patients not adhering to their topical treatments.<sup>3</sup>

37 November 2025 Multifactorial pathogenesis of acne involves 4 key aspects: • Increased sebum in sebaceous glands (80% of lipids produced through DNL) • Abnormal or excessive follicular hyper - keratinization • Accelerated bacterial growth (C. acnes) • Localized inflammatory response Acne Pathogenesis and Potential Role of FASN Inhibitors Heng AHS, Chew FT. Sci Rep. 2020;10(1):5754. 1. O'Farrell M, et al. Sci Rep . 2022;12(1):15661. FASN Palmitate / sapienic acid Lipid synthesis Sebum production Hair Skin Surface Sebum (oil) Inflammation Sebaceous gland Skin With Acne Skin Without Acne Pimple Sebaceous gland FASN is an attractive therapeutic target for acne • Denifanstat directly reduced cutaneous (skin) sebum DNL lipids in two Phase 1 studies • FASN inhibition has potential to reduce inflammation, through decreasing cytokine secretion and Th17 activation 1
