First Quarter 2025 Financial Results Product sales, net: were $78.3 million compared to $24.7 million for the same period in 2024, driven by approximately 72,000 bottles of XDEMVY delivered to patients compared to approximately 26,000 bottles delivered in the prior year period. Cost of sales: were $5.2 million compared to $1.7 million for the same period in 2024, due to manufacturing costs incurred after the approval of XDEMVY, the royalty we pay on net product sales, and the amortization of the milestones paid to our licensor, which is being amortized over its remaining useful life of 8.4 years. Research and development (R&D) expenses: were $14.4 million compared to $12.1 million for the same period in 2024. The increase was primarily due to $0.5 million of increased TP-04 program expenses, $0.9 million of increased payroll and personnel-related costs, $0.9 million of increased early-stage programs, and $0.3 million of increased other indirect expenses. These increases were partially offset by $0.4 million of decreased TP-03 program expenses. Total R&D non-cash stock compensation expense was $1.5 million, which was consistent with $1.5 million in the same period in 2024. Selling, general and administrative (SG&A) expenses: were $85.0 million compared to $51.6 million for the same period in 2024. The increase was due primarily to $9.6 million of increased payroll and personnel-related costs (including non-cash stock-based compensation), and $25.6 million of increased commercial and marketing costs, including direct-to-consumer advertising costs, as we continued our commercial expansion of XDEMVY. These increases were partially offset by $1.9 million of decreased information technology applications, legal, professional and other corporate expenses. Total SG&A non-cash stock compensation expense was $5.3 million, compared with $3.9 million in the same period in 2024. Net loss: was $25.1 million, compared to $35.7 million for the same period in 2024. Basic and diluted net loss per share for the quarter ended March 31, 2025 was $(0.64), compared with $(1.01) for the same period in 2024. Cash position: As of March 31, 2025, cash, cash equivalents and marketable securities were $407.9 million.

About XDEMVY® XDEMVY (lotilaner ophthalmic solution) 0.25%, formerly known as TP-03, is a novel prescription eye drop designed to treat Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. XDEMVY was evaluated in two pivotal trials collectively involving more than 800 patients. Both trials met the primary endpoint and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. Most patients found the XDEMVY eye drop to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were instillation site stinging and burning which was reported in 10% of patients. Other ocular adverse reactions reported by less than 2% of patients were chalazion/hordeolum (stye) and punctate keratitis. XDEMVY Indication and Important Safety Information INDICATIONS AND USAGEXDEMVY is indicated for the treatment of Demodex blepharitis. Most common side effects: The most common side effect in clinical trials was stinging and burning in 10% of patients. Other side effects in less than 2% of patients were chalazion/hordeolum and punctate keratitis. For additional information, please see full prescribing information available at: https://xdemvy.com/. About TP-03TP-03 (lotilaner ophthalmic solution) 0.25% is a novel therapeutic designed to treat Demodex blepharitis by targeting and eradicating the root cause of disease – Demodex mite infestation. It was approved by the FDA in 2023 under the brand name XDEMVY® for the treatment of Demodex blepharitis. Lotilaner is a well-characterized anti-parasitic agent that paralyzes and eradicates Demodex mites by selectively inhibiting parasite-specific gamma-aminobutyric acid-gated chloride (GABA-Cl) channels. It is a highly lipophilic molecule, which may promote its uptake in the oily sebum of the eye lash follicles where the mites reside. About TP-04TP-04 is an investigational aqueous gel formulation of lotilaner, a well-characterized anti-parasitic agent that paralyzes and kills mites by selectively inhibiting parasite-specific GABA-Cl channels. Tarsus is studying TP-04 for the treatment of Ocular Rosacea (OR). About TP-05TP-05 is an investigational oral systemic formulation of lotilaner, a well-characterized anti-parasitic agent that selectively inhibits parasite-specific GABA-Cl channels. TP-05 is believed to be the only non-vaccine, drug-based, preventative therapeutic in development designed to kill ticks to potentially prevent Lyme disease transmission.

CLN-978 is the first and only development-stage CD19 T cell engager to receive U.S. FDA IND clearance in autoimmune diseases Sjögren’s disease represents the third indication under development for CLN-978, and is a disease with high unmet need and no currently approved therapies CAMBRIDGE, MA, USA I April 29, 2025 I Cullinan Therapeutics, Inc. (Nasdaq: CGEM), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today announced that the Company is initiating a study of CLN-978 in patients with Sjögren’s disease (SjD) in the U.S. The Company previously received U.S. Food and Drug Administration (FDA) Investigational New Drug (IND) Application clearance to study the CD19 T cell engager in patients with moderate to severe systemic lupus erythematosus (SLE) and European Medicines Agency (EMA) approval to study CLN-978 in active, difficult-to-treat rheumatoid arthritis. The trial will enroll patients with active, moderate to severe Sjögren’s disease who fulfill the 2016 American College of Rheumatology (ACR)/European Alliance of Associations for Rheumatology (EULAR) classification criteria and are positive for anti-SSA/RO antibodies and/or rheumatoid factor. The dose escalation scheme will be similar to the SLE study. The primary objective of the study is to evaluate the safety and tolerability of CLN-978 in patients with SjD. Secondary objectives include pharmacokinetics, pharmacodynamics, immunogenicity, and effect on disease activity. The Company expects to initiate the study this quarter. “We are pleased to rapidly progress our global clinical development program for CLN-978, now open for patients living with systemic lupus erythematosus, rheumatoid arthritis, and soon Sjögren’s disease,” said Jeffrey Jones, MD, MBA, Chief Medical Officer, Cullinan Therapeutics. “CLN-978, our investigational novel bispecific T cell engager, targets CD19 and offers a highly differentiated approach to deplete B cells deeply with an off-the-shelf product and convenient subcutaneous administration. We are grateful to the investigators in our systemic lupus erythematosus trial who have been enthusiastic partners in our research, and we look forward to opening this new trial to patients with Sjögren’s disease in the U.S.” “Systemic lupus erythematosus and Sjögren’s disease share a complex and often debilitating overlap, leaving many patients struggling with chronic pain, fatigue, and organ involvement,” said Teja Kapoor, MD, Assistant Professor of Medicine at Columbia University College of Physicians and Surgeons in the Division of Rheumatology. “Despite advancements, there remains a significant unmet need for targeted therapies that address the root causes of these autoimmune conditions. I am encouraged by new research approaches such as CLN-978 that aim to modify the disease and offer sustainable relief to patients.” “There are an estimated four million Americans living with Sjögren’s disease, yet it is underdiagnosed and frequently misunderstood,” said Janet Church, President and Chief Executive Officer of the Sjögren’s Foundation. “There are currently no treatments that comprehensively address the complexities of Sjögren’s or slow the progression of the disease. We are encouraged to see new research approaches aimed at providing patients with better treatment options to improve their quality of life.” CLN-978 is being studied in people with SLE in the U.S., Australia, and Europe. CLN-978 will also be studied in people with rheumatoid arthritis at multiple sites in Europe, and in people with SjD at multiple sites in the U.S. and globally. About CLN-978 CLN-978 is a novel, differentiated and highly potent CD19xCD3 bispecific T cell engager. CLN-978 triggers redirected lysis of CD19-expressing target cells in vitro and in vivo . CLN-978 is engineered to achieve very high affinity binding to CD19 to efficiently target B cells, including those with very low CD19 levels. Small in molecular size (65 kDa), CLN-978 contains two single-chain variable fragments, one binding with very high affinity to the CD19 target and the other binding to CD3 on T cells, and a single-domain antibody binding to human serum albumin to extend serum half-life. CLN-978 was developed by an internal Cullinan team and is a wholly owned asset. CLN-978 has the potential to offer a convenient, off-the-shelf, subcutaneously delivered therapeutic option for patients with autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and Sjögren’s disease. About Sjögren’s Disease Sjögren’s disease (SjD) is a chronic autoimmune disease that affects the entire body. 1 While SjD most commonly manifests with extensive dryness, it can also present other serious complications including profound fatigue, chronic pain, major organ involvement, swelling of lymph nodes and glands, arthritis, hematologic abnormalities, neuropathies, and an increased risk of lymphoma. 1-4 SjD can occur alone or alongside other autoimmune diseases such as lupus, rheumatoid arthritis, or scleroderma. 1 Studies suggest the prevalence of SjD in the U.S. is estimated to impact over 250,000 individuals, making it one of the most common rheumatic diseases. 5 Many more people have SjD associated with other autoimmune diseases, and some people with SjD go undiagnosed. While available therapies address dryness and other symptoms, currently no approved treatment has been shown to comprehensively slow disease progression or treat all aspects of SjD. 1,2 About Cullinan Therapeutics Cullinan Therapeutics, Inc.

ZYMFENTRA blocks the action of tumor necrosis factor-alpha (TNF-alpha), a protein that can be overproduced in response to certain diseases and cause the immune system to attack normal, healthy parts of the body. ZYMFENTRA was approved by the FDA through the Biologics License Application (BLA) under the 351 (a) pathway of the Public Health Service Act (a "stand-alone" BLA). ZYMFENTRA is considered a new biologic with a first-approved subcutaneous administration form and thus will be under patent protection for its dosage form by 2037 and for its route of administration by 2040. Indication and Important Safety Information ZYMFENTRA® is a prescription medicine indicated in adults for maintenance treatment of: Moderately-to-severely active Crohn's disease following treatment with an infliximab product administered intravenously. Moderately-to-severely active ulcerative colitis following treatment with an infliximab product administered intravenously. Moderately-to-severely active ulcerative colitis following treatment with an infliximab product administered intravenously. It is not known if ZYMFENTRA is safe and effective in children under 18 years of age. What is the most important information I should know about ZYMFENTRA? SERIOUS INFECTIONS Patients treated with ZYMFENTRA are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis (TB), including reactivation of latent TB. Patients frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent TB before and during treatment with ZYMFENTRA. Treatment for latent infection should be initiated prior to treatment with ZYMFENTRA. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients may present with disseminated, rather than localized, disease. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria. The risks and benefits of treatment with ZYMFENTRA should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Closely monitor patients for the development of signs and symptoms of infection during and after treatment with ZYMFENTRA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Risk of infection may be higher in patients greater than 65 years of age, patients with comorbid conditions and/or patients taking concomitant immunosuppressant therapy. In clinical trials, other serious infections observed in patients treated with infliximab included arthritis bacterial, pneumonia, and urinary tract infection. MALIGNANCIES Malignancies, some fatal, have been reported in children, adolescents, and young adults treated with TNF blockers, including infliximab products. Approximately half of these cases were lymphomas, including Hodgkin's and non-Hodgkin's lymphoma. The other cases represented a variety of malignancies, including rare malignancies that are usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after a median of 30 months after the first dose of therapy. Most of the patients were receiving concomitant immunosuppressants. Post-marketing cases of hepatosplenic T-cell lymphoma, a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including infliximab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported cases have occurred in patients with Crohn's disease or ulcerative colitis, and most were in adolescent and young adult males. Almost all of these patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. Carefully assess the risks and benefits of treatment with ZYMFENTRA, especially in these patient types. In clinical trials of all TNF blockers, more cases of malignancies were observed compared with controls and the expected rate in the general population. In clinical trials of some TNF blockers, including infliximab products, more cases of other malignancies were observed compared with controls. As the potential role of TNF blocker therapy in the development of malignancies is not known, caution should be exercised when considering treatment of patients with a current or a past history of malignancy. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy, including infliximab products. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. CONTRAINDICATIONS ZYMFENTRA is contraindicated in patients with a previous severe hypersensitivity reaction to infliximab-dyyb, other infliximab products, any of the inactive ingredients of ZYMFENTRA or any murine proteins (severe hypersensitivity reactions have included anaphylaxis, hypotension and serum sickness). HEPATITIS B VIRUS REACTIVATION TNF blockers, including infliximab products, have been associated with reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases were fatal. Patients should be tested for HBV infection before initiating ZYMFENTRA. For patients who test positive, consult a physician with expertise in the treatment of hepatitis B. Exercise caution when prescribing ZYMFENTRA for patients identified as carriers of HBV and monitor closely for active HBV infection during and following termination of therapy with ZYMFENTRA. Discontinue ZYMFENTRA in patients who develop HBV reactivation and initiate antiviral therapy with appropriate supportive treatment. Exercise caution when considering resumption of ZYMFENTRA and monitor patients closely. HEPATOTOXICITY Hepatobiliary disorders, including acute liver failure, jaundice abnormal hepatic function, hepatic steatosis, hepatitis, hepatotoxicity, hyperbilirubinemia and non-alcoholic fatty liver, have been reported in patients receiving infliximab products post-marketing. Some cases were fatal or required liver transplant. Aminotransferase elevations were not noted prior to discovery of liver injury in many cases. Patients with symptoms or signs of liver dysfunction should be evaluated for evidence of liver injury. If jaundice and/or marked liver enzyme elevations (eg, ≥5 times the upper limit of normal) develop, ZYMFENTRA should be discontinued and a thorough investigation of the abnormality should be undertaken. CONGESTIVE HEART FAILURE Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. Some cases had a fatal outcome. In several exploratory trials of other TNF blockers in the treatment of CHF, there were greater proportions of TNF-blocker-treated patients who had CHF exacerbations requiring hospitalization or increased mortality. ZYMFENTRA has not been studied in patients with a history of CHF and ZYMFENTRA should be used with caution in patients with CHF. HEMATOLOGIC REACTION Cases of leukopenia, neutropenia, thrombocytopenia and pancytopenia (some fatal) have been reported. The causal relationship to infliximab-product therapy remains unclear. Exercise caution in patients who have ongoing or a history of significant hematologic abnormalities. Advise patients to seek immediate medical attention if they develop signs and symptoms of blood dyscrasias or infection. Consider discontinuation of ZYMFENTRA in patients who develop significant hematologic abnormalities. HYPERSENSITIVITY AND OTHER ADMINISTRATION REACTIONS In post-marketing experience, serious systemic hypersensitivity reactions (including anaphylaxis, hypotension and serum sickness) have been reported following administration of infliximab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. INJECTION SITE REACTIONS In clinical studies, localized injection-site reactions were reported following administration of ZYMFENTRA. If a clinically significant injection-site reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. NEUROLOGIC REACTIONS Agents that inhibit TNF have been associated with central nervous system (CNS) manifestation of systemic vasculitis, seizure and new onset or exacerbation of CNS demyelinating disorders, including multiple sclerosis and optic neuritis and peripheral demyelinating disorders, including Guillain-Barré syndrome. Exercise caution when considering ZYMFENTRA in patients with these disorders and consider discontinuation if these disorders develop. RISK OF INFECTION WITH CONCURRENT ADMINISTRATION OF OTHER BIOLOGICS PRODUCTS Serious infections and neutropenia have been reported with concurrent use of ZYMFENTRA with other immunosuppressive biological products. The concurrent use of ZYMFENTRA with other immunosuppressive biological products used to treat UC and CD may increase the risk of infection and is not recommended. RISK OF ADDITIVE IMMUNOSUPPRESSIVE EFFECTS FROM PRIOR BIOLOGICAL PRODUCTS Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA. AUTOIMMUNITY Treatment with TNF blockers may result in the formation of autoantibodies and in the development of a lupus-like syndrome. Discontinue ZYMFENTRA treatment if symptoms of a lupus-like syndrome develop. VACCINATIONS AND USE OF LIVE VACCINES/THERAPEUTIC INFECTIOUS AGENTS Prior to initiating ZYMFENTRA, update vaccinations in accordance with current vaccination guidelines. Live vaccines or therapeutic infectious agents should not be given with ZYMFENTRA due to the possibility of clinical infections, including disseminated infections. At least a 6-month waiting period following birth is recommended before the administration of any live vaccine to infants exposed in utero to ZYMFENTRA. ADVERSE REACTIONS In clinical trials with ZYMFENTRA, the most common adverse reactions occurring in ≥3% of ZYMFENTRA-treated patients included site reactions, COVID-19, anemia, arthralgia, infection site reaction, increased alanine aminotransferase and abdominal pain for UC, and COVID-19, headache, upper respiratory tract infection, injection site reaction, diarrhea, increased blood creatine phosphokinase, arthralgia, increased alanine aminotransferase, hypertension, urinary tract infection, neutropenia, dizziness and leukopenia for CD.
