Celcuity Reports Fourth Quarter and Full Year 2018 Financial Results

Minneapolis, Minnesota—February 26, 2019—Celcuity Inc. (Nasdaq: CELC), a functional cellular analysis company that is discovering new cancer subtypes and commercializing diagnostic tests designed to significantly improve clinical outcomes of cancer patients treated with targeted therapies, announced financial results for the fourth quarter and year ended December 31, 2018.

Unless otherwise stated, all comparisons are for the fourth quarter and year ended December 31, 2018, compared to the fourth quarter and year ended December 31, 2017.

Celcuity reported a net loss of $1.8 million, or $0.18 per share, for the fourth quarter of 2018, compared to a net loss of $1.7 million, or $0.17 per share, for the fourth quarter of 2017. Net loss for fiscal year 2018 was $7.5 million, or $0.74 per share, compared to $6.3 million, or $0.84 per share, for fiscal year 2017. Non-GAAP adjusted net loss was $1.6 million, or $0.15 per share, for the fourth quarter of 2018, compared to non-GAAP adjusted net loss of $1.4 million, or $0.14 per share, for the fourth quarter of 2017. Non-GAAP adjusted net loss for the fiscal year 2018 was $6.3 million, or $0.62 per share, compared to $4.9 million, or $0.66 per share, for the fiscal year 2017. Non-GAAP adjusted net loss excludes stock-based compensation expense and non-cash interest expense. Because these items have no impact on the cash position of the Company, management believes Non-GAAP adjusted net loss better enables Celcuity to focus on cash used in operations. For a reconciliation of financial measures in accordance with generally accepted accounting principles of the United States (GAAP) to non-GAAP financial measures in this release, please see the financial tables at the end of this news release.

Net cash used in operating activities for the fourth quarter of 2018 was $1.5 million. Net cash used in operating activities for fiscal year 2018 was $6.1 million. At December 31, 2018, Celcuity had cash, cash equivalents and investments of $24.9 million, compared to cash, cash equivalents and investments of $31.4 million at December 31, 2017.

“We made significant progress in 2018 and achieved many of our critical objectives. Our first clinical trial, FACT 1, was activated in collaboration with Genentech and the NSABP Foundation. The FACT 1 trial is evaluating the safety and efficacy of Genentech’s drugs, Herceptin® and Perjeta®, and chemotherapy, in breast cancer patients selected with Celcuity’s CELx HSF Test. We signed a clinical trial agreement with Puma Biotechnology, Inc. and West Cancer Center to conduct a Phase II clinical trial, known as FACT 2, to evaluate the efficacy and safety of Puma’s drug, Nerlynx®, and chemotherapy, in breast cancer patients selected with Celcuity’s CELx HSF Test. We were also selected by NSABP and Puma Biotechnology, Inc. to evaluate tissue samples from a Phase II study evaluating Puma Biotechnology’s pan-HER inhibitor, Nerlynx, Genentech’s HER2 antibody, Herceptin, and Bristol-Myers Squibb’s EGFR inhibitor, Erbitux, in metastatic colorectal cancer patients.

“We completed development of our second CELx signaling function Test for HER2-negative breast cancer. This second test identifies HER2-negative breast cancer patients who have hyperactive and co-activated HER family and c-Met signaling activity. We also advanced development of several new CELx signaling function tests to diagnose new cancer sub-types, including a third test for breast cancer and tests for two new tumor tissue types. Additionally, we presented results of several pre-clinical studies at major conferences, including the American Society of Clinical Oncology Annual Meeting, the Miami Breast Cancer Conference, and the San Antonio Breast Cancer Symposium.”

Mr. Sullivan added, “The FACT 1 clinical trial that is evaluating Genentech’s targeted therapies in patients our CELx HSF test selects now has 14 activated sites. While this is consistent with our goal at the beginning of 2018, the enrollment rate of patients at these sites has been lower than NSABP’s original expectations. To offset the lower than expected enrollment rate, NSABP has agreed to activate up to 16 additional sites, for a total of 30 sites. We expect the addition of these sites will increase Celcuity’s cost for the FACT 1 trial by up to $650,000. We now expect interim results from this trial in late 2019 and final results approximately nine months later.

“The FACT 2 clinical trial that is evaluating Puma’s targeted therapy, Nerlynx, in patients our CELx HSF test selects has received all required regulatory and Institutional Review Board approvals and is expected to be activated later in early 2019. We expect interim results from this trial in late 2019 or early 2020 and final results approximately 12 months later.

“As we look ahead to the remainder of 2019, we anticipate completing development of another cell signaling function test for breast cancer that diagnoses a new sub-type of breast cancer not currently detected with a molecular test. We also anticipate completing development of tests for two new tumor types. Each of these new tests would increase the opportunities for us to provide companion diagnostics that enable pharmaceutical companies to obtain new drug indications for the cancer sub-types our tests diagnose. We also hope to initiate at least one additional clinical collaboration with a pharmaceutical company by year-end to study breast cancer patients identified by our CELx MP test with hyperactive and co-activated HER family and c-Met signaling activity.”

Operating Expenses

Total operating expenses were $2.0 million for the fourth quarter of 2018, compared to $1.8 million for the fourth quarter of 2017. Operating expenses for fiscal year 2018 were $7.9 million, compared to $6.0 million for fiscal year 2017.

Research and Development Expenses:

Research and development (R&D) expenses were $1.6 million for the fourth quarter of 2018, compared to $1.4 million for the fourth quarter of 2017. R&D expenses for fiscal year 2018 were $6.3 million, compared to $5.0 million for fiscal year 2017. The approximately $1.3 million increase during fiscal year 2018, compared to fiscal year 2017, resulted primarily from a $0.6 million increase in compensation related expenses to support development of our CELx platform. In addition, other R&D expenses increased $0.7 million due to clinical validation and laboratory studies, legal expenses related to patent costs and operational and business development activities.

General and Administrative Expenses:

General and administrative (G&A) expenses were $0.3 million for the fourth quarter of 2018, compared to $0.4 million for the fourth quarter of 2017. G&A expenses for fiscal year 2018 were $1.6 million, compared to $1.0 million for fiscal year 2017. The approximately $0.6 million increase during fiscal year 2018, compared to fiscal year 2017, primarily resulted from a $0.4 million increase in professional fees associated with being a public company for a full year versus only one quarter in 2017, and director and officer insurance. Other G&A expenses increased $0.2 million in compensation related expenses, including non-cash stock-based compensation.

Cautionary Statement Regarding Non-GAAP Financial Measures

This news 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 and non-cash interest expense from net loss and net loss per share. Management excludes these items because it does not impact the cash position of the Company, 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. Therefore, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may not be comparable to similar measures presented by other issuers. 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. 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 and accordingly, may not be comparable to similarly titled measures used by other companies.
