Full Press Release Details
THOUSAND OAKS, Calif.--(BUSINESS WIRE)--Atara Biotherapeutics, Inc.(Nasdaq: ATRA), a leader in T-cell immunotherapy, leveraging its novel allogeneic Epstein-Barr virus (EBV) T-cell platform to develop transformative therapies for patients with cancer and autoimmune diseases, today reported financial results for the fourth quarter and full year 2025 and business updates.
“We continue to focus on streamlining our costs and liabilities, allowing us to be a nimbler, fit for purpose organization,” said Cokey Nguyen Ph.D., President and Chief Executive Officer of Atara. “With the adjustments we have made we are able to focus on supporting our partner, Pierre Fabre Pharmaceuticals, as they work towards addressing the concerns in the latest Complete Response Letter with the agency. We strongly believe that tabelecleucel can bring substantial benefit to post-transplant lymphoproliferative disease patients and we are committed to supporting Pierre Fabre Pharmaceuticals as they get this life-saving drug to the finish line in the U.S.”
Tabelecleucel (tab-cel®or Ebvallo™) for Post-Transplant Lymphoproliferative Disease (PTLD)
A Type A meeting with the U.S. Food and Drug Administration (FDA) has been scheduled for our partner Pierre Fabre Pharmaceuticals to discuss the issues raised by the FDA in the Complete Response Letter received in January 2026. We anticipate providing a regulatory update in the second quarter.
Corporate Updates
As previously communicated, Atara entered into an amendment (Amendment) to the Purchase and Sale Agreement dated as of December 20, 2022 with a fund managed by HealthCare Royalty (“HCRx”). Under the terms of the Amendment, HCRx agreed to amend the due date of the one-time $9.0 million cash payment associated with the achievement of a certain milestone from June 30, 2026 to January 1, 2028 in exchange for the issuance of a warrant to purchase up to 400,000 shares of Atara common stock.
Financial Update:
Fourth Quarter and Full Year 2025 Financial Results:
• Cash, cash equivalents and short-term investments as of December 31, 2025 totaled $8.5 million, as compared to $42.5 million as of December 31, 2024.
• Net cash used in operating activities was $5.7 million and $50.9 million for the fourth quarter and fiscal year 2025, as compared to $24.5 million and $68.7 million for the same periods in 2024.
• Atara reported a net loss of ($3.4) million, or ($0.25) per share, and a net income of $32.7 million, or $2.61 per share, for the fourth quarter and fiscal year 2025, respectively, as compared to a net loss of ($12.7) million, or ($1.19) per share, and ($85.4) million, or ($11.41) per share, for the same periods in 2024.
• Commercialization revenues were $120.8 million in 2025 as compared to $128.9 million in 2024.
• Total costs and operating expenses include non-cash stock-based compensation, depreciation and amortization expenses of $1.6 million and $11.9 million for the fourth quarter and fiscal year 2025, respectively, as compared to $6.9 million and $32.1 million for the same periods in 2024.

2026 Outlook and Cash Runway:
• Operating expenses are expected to continue to decline significantly year-over-year as a result of the comprehensive cost-reduction initiatives completed in 2025.
• Atara expects that cash, cash equivalents and short-term investments as of December 31, 2025, combined with recent ATM proceeds of $3.0 million and the operating efficiencies realized in 2025, will be sufficient to fund planned operations through year-end 2026.
