Citius Oncology, Inc. Reports Fiscal Third Quarter 2026 Financial Results and Provides Business Update

$7.1 million in revenue for the first nine months of fiscal 2026 as the LYMPHIR^® launch progresses

Strong institutional demand drives growth in total vials ordered and number of institutions ordering

LYMPHIR ordered by 44 institutions since launch

CRANFORD, N.J., Aug. 14, 2026 /PRNewswire/ -- Citius Oncology, Inc. ("Citius Oncology" or the "Company") (Nasdaq: CTOR), an oncology-focused biopharmaceutical company and majority-owned subsidiary of Citius Pharmaceuticals, Inc. ("Citius Pharma") (Nasdaq: CTXR), today reported financial results for the fiscal third quarter ended June 30, 2026, and provided a business update.

"Institutional demand (LYMPHIR vials ordered by prescribing centers from wholesalers) is accelerating. Institutional vial orders grew 31% sequentially, from 708 in the quarter ended March 31, 2026 to 926 in the quarter ended June 30, 2026. In July, institutions ordered 383 vials from wholesalers, the largest order month to date, reflecting a 25% increase over the prior quarter's monthly average order. Currently, 44 institutions have prescribed and ordered LYMPHIR," said Leonard Mazur, Chairman and Chief Executive Officer of Citius Oncology.

"We expect continued institutional demand to drive new wholesaler orders. The Company recognizes revenue when wholesaler orders are fulfilled. Consequently, net revenue for any period reflects actual wholesaler orders fulfilled. In July, we began to see growth in institutional demand translate into increased wholesale orders and associated revenue. The positive trajectory of formulary approvals, institutional adoption, and unit demand gives us confidence in a robust remainder of the fiscal year," added Mazur.

"We generated initial momentum with a lean internal team, maintaining healthy product margins and securing broad market access. In August, our full 29-person-strong commercial and medical affairs organizations expanded to nationwide coverage. The teams are now positioned to accelerate commercial execution and support broader adoption by leveraging the comprehensive, scalable infrastructure already established for LYMPHIR, including patient hub services, marketing and reimbursement support. Citius Oncology is now well positioned to broaden engagement with treatment centers, targeting formulary inclusion at 100 priority institutions by year-end and first-in-class support for health care providers. At the same time, we continue to advance LYMPHIR's longer-term value proposition through investigator-initiated studies exploring its potential in combination regimens beyond CTCL," added Mazur.

"Overall, the launch is moving in the right direction: more institutions are ordering LYMPHIR, vial demand is increasing, and our commercial footprint is expanding. We believe the underlying increasing demand trends provide a strong basis for the remainder of fiscal 2026," concluded Mazur.

About LYMPHIR™ (denileukin diftitox-cxdl)
LYMPHIR is a targeted immune therapy for relapsed or refractory cutaneous T-cell lymphoma (CTCL) indicated for use in Stage I-III disease after at least one prior systemic therapy. It is a recombinant fusion protein that combines the IL-2 receptor binding domain with diphtheria toxin (DT) fragments. The agent specifically binds to IL-2 receptors on the cell surface, causing diphtheria toxin fragments that have entered cells to inhibit protein synthesis, resulting in cell death. Denileukin diftitox-cxdl has demonstrated the ability to deplete immunosuppressive regulatory T lymphocytes (Tregs) and antitumor activity through a direct cytocidal action on IL-2R-expressing tumors. LYMPHIR was approved by the FDA and subsequently launched in the U.S. in December 2025.
