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

MINNEAPOLIS, May 14, 2025 — Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced financial results for the first quarter ended March 31, 2025 and other recent business developments.

“We continue to make steady progress across our pipeline with several critical data catalysts anticipated this year,” said Brian Sullivan, CEO and co-founder of Celcuity. “We now expect to report topline data for the PIK3CA wild-type cohort of the VIKTORIA-1 trial in the third quarter of this year and to report topline data for the PIK3CA mutant cohort in the fourth quarter of 2025. If our topline data from the WT cohort is positive, we expect the data will support the filing of our first new drug application and, if approved, our transition to a commercial stage company.”

First Quarter 2025 Business Highlights and Other Recent Developments

First Quarter 2025 Financial Results

Unless otherwise stated, all comparisons are for the first quarter ended March 31, 2025, compared to the first quarter ended March 31, 2024.

Total operating expenses were $36.1 million for the first quarter of 2025, compared to $22.5 million for the first quarter of 2024.

Research and development (“R&D”) expenses were $32.2 million for the first quarter of 2025, compared to $20.6 million for the prior-year period. Of the approximately $11.6 million increase in R&D expenses, $5.9 million primarily related to increased employee and consulting expenses. The remaining $5.7 million primarily related to activities supporting our ongoing clinical trials.

General and administrative (“G&A”) expenses were $3.9 million for the first quarter of 2025, compared to $1.8 million for the prior-year period. Increased employee and consulting expenses accounted for $1.6 million of the increase. Professional fees, expanding infrastructure and other administrative expenses accounted for the remaining increase of approximately $0.5 million.

Net loss for the first quarter of 2025 was $37.0 million, or $0.86 loss per share, compared to a net loss of $21.6 million, or $0.64 loss per share, for the first quarter of 2024. Non-GAAP adjusted net loss for the first quarter of 2025 was $34.7 million, or $0.81 loss per share, compared to non-GAAP adjusted net loss of $19.9 million, or $0.59 loss per share, for the first 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 first quarter of 2025 was $35.9 million, compared to $17.1 million for the first quarter of 2024.

At March 31, 2025, Celcuity reported cash, cash equivalents and short-term investments of $205.7 million. We expect cash, cash equivalents, investments and drawdowns on our debt facility to fund current clinical development program activities through 2026.

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 PI3K/AKT/mTOR (“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- advanced breast cancer is currently enrolling patients. More detailed information about the VIKTORIA-1 study can be found at ClinicalTrials.gov. A Phase 1b/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic castration resistant prostate cancer, is ongoing. 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- advanced breast cancer is currently recruiting patients. Celcuity is headquartered in Minneapolis. Further information about Celcuity can be found at www.celcuity.com . Follow us on LinkedIn and Twitter.

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.
