Celcuity Inc. Reports Third Quarter 2025 Financial Results and Provides Corporate Update

MINNEAPOLIS, November 12, 2025 — Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced financial results for the third quarter ended September 30, 2025 and other recent business developments.

“We made significant clinical and regulatory progress in the third quarter,” said Brian Sullivan, CEO and co-founder of Celcuity. “At the ESMO Congress, we presented potentially practice-changing safety and efficacy results for the gedatolisib regimens from the PIK3CA wild-type cohort of our Phase 3 VIKTORIA-1 trial at a late breaking oral presentation. We remain on track to submit the New Drug Application for gedatolisib later this year based on data from the PIK3CA wild-type cohort. The PIK3CA mutant cohort of the Phase 3 VIKTORIA-1 clinical trial is fully enrolled with topline data expected in late Q1 2026 or during Q2 2026.”

“There is an urgent need for more efficacious therapies than those currently available for patients with HR+, HER2- advanced breast cancer who have received prior treatment with a CDK4/6 inhibitor. With our strengthened balance sheet, and unprecedented efficacy results in this patient population, we are well positioned to bring gedatolisib to patients should we get FDA approval.”

Third Quarter 2025 Business Highlights and Other Recent Developments

Third Quarter 2025 Financial Results

Unless otherwise stated, all comparisons are for the third quarter ended September 30, 2025, compared to the third quarter ended September 30, 2024.

Total operating expenses were $42.8 million for the third quarter of 2025, compared to $30.1 million for the third quarter of 2024.

Research and development (“R&D”) expenses were $34.9 million for the third quarter of 2025, compared to $27.6 million for the prior-year period. Of the approximately $7.3 million increase in R&D expenses, $5.6 million was related to increased employee and consulting expenses, $3.2 million of which related to commercial headcount additions and other launch-related activities. The remaining $1.7 million increase was primarily related to activities supporting our ongoing clinical trials.

General and administrative (“G&A”) expenses were $7.9 million for the third quarter of 2025, compared to $2.5 million for the prior-year period. Of the approximately $5.4 million increase in general and administrative expenses, $4.9 million was related to increased employee and consulting expenses. Of this $4.9 million increase, $4.0 million was related to non-cash, stock-based compensation. The remaining $0.5 million of the $5.4 million increase was primarily related to professional fees, expanding infrastructure and other administrative expenses.

Net loss for the third quarter of 2025 was $43.8 million, or $0.92 loss per share, compared to a net loss of $29.8 million, or $0.70 loss per share, for the third quarter of 2024. Non-GAAP adjusted net loss for the third quarter of 2025 was $37.2 million, or $0.78 loss per share, compared to non-GAAP adjusted net loss of $27.6 million, or $0.65 loss per share, for the third quarter of 2024. Non-GAAP adjusted net loss excludes stock-based compensation expense, non-cash interest expense, and non-cash interest income. Because these items have no impact on Celcuity’s cash position, management believes non-GAAP adjusted net loss better enables Celcuity to focus on cash used in operations. For a reconciliation of financial measures calculated in accordance with generally accepted accounting principles in the United States (“GAAP”) to non-GAAP financial measures, please see the financial tables at the end of this press release.

Net cash used in operating activities for the third quarter of 2025 was $44.8 million, compared to $20.6 million for the third quarter of 2024.

At September 30, 2025, Celcuity reported cash, cash equivalents and short-term investments of $455.0 million. We expect cash, cash equivalents, investments and drawdowns on our debt facility to fund operations through 2027.

About Celcuity

Celcuity is a clinical-stage biotechnology company pursuing development of targeted therapies for treatment of multiple solid tumor indications. The company’s lead therapeutic candidate is gedatolisib, a potent, pan-PI3K and mTORC1/2 inhibitor that comprehensively blockades the PAM pathway. Its mechanism of action and pharmacokinetic properties are differentiated from other currently approved and investigational therapies that target PI3Kα, AKT, or mTORC1 alone or together. A Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- ABC has completed enrollment and the company has reported detailed results for the PIK3CA WT cohort, and has completed enrollment of patients for the PIK3CA mutant cohort. A Phase 3 clinical trial, VIKTORIA-2, evaluating gedatolisib plus a CDK4/6 inhibitor and fulvestrant as first-line treatment for patients with HR+/HER2- ABC is currently enrolling patients. A Phase 1/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic castration resistant prostate cancer, is ongoing. More detailed information about Celcuity’s active clinical trials can be found at ClinicalTrials.gov . Celcuity is headquartered in Minneapolis.

Cautionary Statement Regarding Non-GAAP Financial Measures

This press release contains references to non-GAAP adjusted net loss and non-GAAP adjusted net loss per share. Management believes these non-GAAP financial measures are useful supplemental measures for planning, monitoring, and evaluating operational performance as they exclude stock-based compensation expense, non-cash interest expense, and non-cash interest income from net loss and net loss per share. Management excludes these items because they do not impact Celcuity’s cash position, which management believes better enables Celcuity to focus on cash used in operations. However, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share are not recognized measures under GAAP and do not have a standardized meaning prescribed by GAAP. As a result, management’s method of calculating non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may differ materially from the method used by other companies. Therefore, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may not be comparable to similarly titled measures presented by other companies. Investors are cautioned that non-GAAP adjusted net loss and non-GAAP adjusted net loss per share should not be construed as alternatives to net loss, net loss per share or other statements of operations data (which are determined in accordance with GAAP) as an indicator of Celcuity’s performance or as a measure of liquidity and cash flows.
