Citius Oncology, Inc. Reports Fiscal Second Quarter 2025 Financial Results and Provides Business Update

CRANFORD, N.J., May 14, 2025 -- Citius Oncology, Inc. (“Citius Oncology” or the “Company”) (Nasdaq: CTOR), a specialty biopharmaceutical company focused on the development and commercialization of novel targeted oncology therapies, today reported business and financial results for the fiscal second quarter ended March 31, 2025.

“In Q2 2025, Citius Oncology advanced its transformation from a development-stage company to a commercial-stage organization. Following FDA approval of LYMPHIR, we intensified our focus on disciplined capital deployment and operational execution to support the success of our planned U.S. launch,” said Leonard Mazur, Chairman and CEO of Citius Oncology and Citius Pharmaceuticals.

“This quarter’s progress underscores our commitment to creating long-term value by ensuring LYMPHIR reaches patients with cutaneous T-cell lymphoma. Discussions with prospective commercial and strategic partners are underway as we concurrently pursue opportunities to secure additional capital to enhance our financial flexibility. These efforts are critical as we lay the foundation for sustained commercial success. With disciplined execution and a focused strategic vision, we believe Citius Oncology is poised to deliver meaningful near-term impact and durable shareholder value,” concluded Mazur.

Fiscal SECOND quarter 2025 Financial Results:

Liquidity

Citius Oncology is a subsidiary of Citius Pharma. Citius Pharma plans to continue to fund Citius Oncology until Citius Oncology raises adequate capital through equity financings from outside investors and/or generates revenue from the future sales of LYMPHIR. Citius Oncology has also retained Jefferies LLC as exclusive financial advisor to evaluate strategic alternatives aimed at maximizing stockholder value.

As of March 31, 2025, the Company had $112 in cash and cash equivalents and 71,552,402 common shares outstanding. Citius Oncology will need to secure additional capital to support operations beyond May 2025.

Research and Development (R&D) Expenses

R&D expenses were $3.1 million for the quarter ended March 31, 2025, as compared to $1.3 million for the quarter ended March 31, 2024. For the six months ended March 31, 2025, R&D expenses were $4.4 million, as compared to $2.5 million for the six months ended March 31, 2024. The increase is primarily related to costs associated with the expense of a drug substance batch needed for the pre-license inspection of the manufacturer.

General and Administrative (G&A) Expenses

G&A expenses were $2.2 million for the quarter ended March 31, 2025, as compared to $1.4 million for the quarter ended March 31, 2024. For the six months ended March 31, 2025, G&A expenses were $5.5 million, as compared to $2.9 million for the six months ended March 31, 2024. The increase was primarily due to costs associated with pre-commercial and commercial launch activities of LYMPHIR including market research, marketing, distribution and drug product reimbursement from health plans and payers.

For the quarter ended March 31, 2025, stock-based compensation expense was $2.1 million, as compared to $2.0 million for the quarter ended March 31, 2024. For the six months ended March 31, 2025, stock-based compensation expense was $3.9 million, as compared to $3.9 million for the six months ended March 31, 2024.

Net loss for the six months ended March 31, 2025 was $14.4 million, as compared to a net loss of $9.6 million for the six months ended March 31, 2024. The increase in net loss was primarily due to the increase in our operating expenses.
