Breaking Down RemeGen Co., Ltd. Financial Health: Key Insights for Investors

From a 2008 Yantai lab founded by Yantai Rongchang and co-founders Weidong Wang and Dr. Jianmin Fang to a Hong Kong IPO in 2020, RemeGen has evolved into a vertically integrated biopharma with a global footprint-research sites in Beijing, Shanghai, San Francisco and Washington-and a commercial portfolio anchored by Disitamab Vedotin and Telitacicept; today the company trades under 9995.HK, carries a market capitalization of about HK$47.01 billion (as of December 15, 2025), and reported revenue of RMB 1.719 billion for the nine months ended September 30, 2025 (up 42.3% year‑over‑year) while narrowing its loss to RMB 550.70 million from RMB 1.071 billion a year earlier-figures driven by a pipeline of ADCs, fusion proteins and bispecifics (RC48, RC18, RC88, RC198) developed on three proprietary platforms and commercial partnerships such as with Seagen/Pfizer-yet the firm is still investing heavily in R&D and sustainability targets, employs 2,999 people as of December 2024 (a 17.04% headcount reduction year‑over‑year), and is positioning itself to convert clinical momentum into long‑term value across autoimmune, oncology and ophthalmology markets.

RemeGen Co., Ltd. (9995.HK): Mission and Values

• Founded: 2009
• Stock ticker: 9995.HK
• Global R&D presence: Beijing, Shanghai, San Francisco, Washington
• Core focus: therapeutic antibodies - ADCs, fusion proteins, monoclonal and bispecific antibodies

• Discovery & platform engineering: three self-developed technology platforms - antibody & fusion protein, ADC, and hinge-insertion bispecific (HIBODY) - used to generate and optimize lead molecules.
• Preclinical & translational: in-house pharmacology, toxicology and PK/PD assessment to de-risk IND-enabling studies.
• Clinical development: internal clinical operations and CRO partnerships to run Phase I-III trials across China and internationally.
• Manufacturing: GMP biologics production to supply clinical and commercial demand, enabling vertical capture of value.

• RC88 - a mesothelin-targeting ADC advancing in clinical studies for mesothelin-expressing solid tumors; positioned as a core oncology asset.
• RC198 - a PD-L1 x 4-1BB hinge-insertion bispecific antibody (HIBODY) designed to deliver localized 4-1BB co-stimulation in PD-L1-positive tumor microenvironments; an immuno-oncology asset in clinical development.
• Additional ADCs, fusion proteins and monoclonal antibodies in various stages from IND-enabling to late-stage clinical trials, reflecting a diversified pipeline across oncology, autoimmune and ophthalmology.

RemeGen Co., Ltd. (9995.HK): How It Works

• Discovery & preclinical R&D: antibody engineering, ADC linker/toxin optimization and biologics formulation.
• Clinical development: multi-center Phase II/III programs for indications of Telitacicept (e.g., SLE, IgA nephropathy) and RC48 (HER2-expressing cancers).
• Regulatory & approval: domestic filings in China plus ex-China collaborations (out-licensing) for broader commercialization.
• Manufacturing & supply: internal biologics/ADC production capacity to supply China market and support partner obligations.
• Commercialization: direct sales in China, hospital tendering, specialty oncology and autoimmune clinic channels, plus partner-led international launches.

• Product sales - primary revenue source from Telitacicept and Disitamab Vedotin prescriptions, hospital procurement and outpatient specialty clinics.
• Partner milestones and royalties - licensing deals (e.g., Seagen/Pfizer partnership for out-of-China development/commercialization) generate upfronts, milestones and royalties tied to approvals and sales outside China.
• Service and manufacturing income - contract manufacturing or technical services for collaborators (smaller contribution vs. product sales).

• Product mix: expanding prescriptions of Telitacicept across autoimmune indications and uptake of RC48 in HER2-low/positive tumors drive top-line growth.
• Pricing & reimbursement: hospital tender wins and National Reimbursement Drug List (NRDL) negotiations materially affect realized ASPs (average selling prices) and volumes.
• R&D spend: continued investment in new indications, combination studies and global trials increases operating expenses and suppresses near-term net profitability.
• Partner economics: out-licensing deals transfer ex-China commercialization costs to partners while delivering milestone/royalty income to RemeGen, improving cash flow leverage as international launches scale.

• Discovery → IND/CTA filings → Clinical trials (Phase I-III) → Regulatory approval → Manufacturing scale-up → Hospital/clinic commercialization → Revenue collection and potential royalty income from partners.

• Seagen (now part of Pfizer): partnered development and commercialization for Disitamab Vedotin outside China - provides development capabilities, regulatory reach and commercial infrastructure that accelerate global sales and royalty streams back to RemeGen.

RemeGen Co., Ltd. (9995.HK): How It Makes Money

• Core revenue drivers: commercial sales of approved monoclonal antibodies and ADCs, royalties/licensing fees, and milestone payments from strategic partners.
• R&D-to-commercial pathway: advancing pipeline assets through clinical stages to capture larger market share in oncology, autoimmune and ophthalmic indications.
• Geographic mix: strong China commercialization base with selective overseas partnerships to broaden addressable markets.

• Pipeline strength: multiple candidates in advanced clinical development, providing near- to mid-term opportunities for new product launches and royalty streams.
• Strategic partnerships: licensing and co-development agreements that deliver upfront payments, milestones, and shared commercialization economics.
• Sustainability and corporate reputation: active emission-reduction initiatives aligned with global ESG trends, supporting investor confidence and brand value.
