Earnings-related releases often paired rich clinical or strategic updates with volatile, frequently negative, next-day price moves.
Across recent earnings updates, Tempest has repeatedly combined financial results with significant strategic or clinical news. Year-end 2024 and 2025 results highlighted growing R&D and net losses alongside progress for amezalpat and TPST-1495. Quarterly 2025 calls emphasized shrinking cash balances, strategic alternatives, and later the pivot toward CAR-T and asset acquisitions. Price reactions have been mixed, with several earnings days showing sharp declines despite constructive pipeline commentary, suggesting sensitivity to balance sheet and dilution concerns.
Historical Comparison
Past earnings releases for TPST moved the stock by an average of -0.93%. Today’s -4.17% reaction is a larger-than-usual downside move versus typical earnings-day volatility.
Earnings updates show a shift from amezalpat- and TPST-1495-focused development in 2024–2025 toward dual-targeting CAR-T assets and the Factor/Erigen acquisition by early 2026.
Regulatory & Risk Context
An effective Form S-3 dated 2026-04-01 registers 2,777,781 common shares for resale from a March 20, 2026 private placement. The company will not receive proceeds from these resale transactions, though it may receive cash upon warrant exercises. Two related 424B3 prospectuses on 2026-04-10 reflect active usage of this resale shelf.
Market Pulse Summary
The stock dropped -12.4% in the session following this news. A negative reaction despite encouraging TPST-2003 efficacy data fits prior patterns where earnings updates highlighted shrinking cash and sizeable losses. With cash at $1.8M and acquired in-process R&D expenses of $22.1M, balance sheet and dilution concerns can overshadow positive science. Existing S-3 resale capacity for 2,777,781 shares and recent warrant-linked financing may reinforce worries about future equity issuance when interpreting the quarter’s results.

Announced positive interim data from the ongoing REDEEM-1 Phase 1/2a trial of TPST-2003 in patients with relapsed/refractory multiple myeloma (rrMM)
Announced Cincinnati Children’s Applied Gene and Cell Therapy Center (“AGCTC”) as Lead Manufacturing Partner
Appointed Andrew Fang, Ph.D., as Head of Business Development
BRISBANE, Calif., May 14, 2026 (GLOBE NEWSWIRE) -- Tempest Therapeutics, Inc. (Nasdaq: TPST) (“Tempest”), a clinical-stage biotechnology company developing a pipeline of advanced CAR-T cell therapy product candidates to treat cancer, today reported financial results for the quarter ended March 31, 2026, and provided a corporate update.
“We made strong progress in the first quarter as we continued to execute across our lead program TPST-2003,” said Matt Angel, Ph.D., President and Chief Executive Officer of Tempest. “We advanced key activities supporting the planned initiation of our U.S. registrational study of TPST-2003 in patients with rrMM, including announcing our lead manufacturing partner AGCTC and taking delivery of the TPST-2003 lentiviral vector, a critical component in the manufacturing of TPST-2003. At the same time, we strengthened our ability to unlock value across our remaining portfolio with the appointment of Andrew Fang, Ph.D., as our Head of Business Development, whose focus on strategic partnerships, licensing and corporate transactions will help position us for long-term growth. We believe these milestones further reinforce our momentum and our path toward delivering meaningful impact for patients and shareholders alike.”
Recent Highlights
- TPST-2003
- Positive interim results across two ongoing clinical trials (REDEEM-1 Phase 1/2a trial of TPST-2003 in patients with rrMM, and POEMS-1 Phase 1 trial evaluating TPST-2003 in the rare disease, POEMS syndrome), both of which are being sponsored and conducted by Tempest’s partner, Novatim Immune Therapeutics:
100% complete response (CR) rate among all 15 CAR-T-naïve efficacy evaluable patients treated with TPST-2003 across REDEEM-1 and POEMS-1 trials.- Favorable safety profile with no Grade ≥3 cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) in REDEEM-1 trial appears to be emerging as a potentially differentiating attribute in its class.
- Prior investigator-initiated trial (IIT) reached median progression free survival (PFS) of 23.1 months, including in patients with extramedullary disease.
- 44 patients with rrMM treated to date across three studies.
- The selection of Cincinnati Children’s AGCTC as the lead contract development and manufacturing partner to conduct the formal technology transfer of TPST-2003, Tempest’s dual-targeting CD19/BCMA CAR-T therapy under development for the treatment of relapsed/refractory multiple myeloma (rrMM). Further to the selection of AGCTC as lead partner, AGCTC took delivery of the TPST-2003 lentiviral vector, a critical component used in the manufacturing of TPST-2003, supporting plans to initiate the first potentially registrational study to evaluate a dual-targeting CAR-T therapy in patients with rrMM, including patients who are experiencing extramedullary disease (EMD), later this year.
- Positive interim results across two ongoing clinical trials (REDEEM-1 Phase 1/2a trial of TPST-2003 in patients with rrMM, and POEMS-1 Phase 1 trial evaluating TPST-2003 in the rare disease, POEMS syndrome), both of which are being sponsored and conducted by Tempest’s partner, Novatim Immune Therapeutics:
- Corporate:
- Announced the appointment of Andrew Fang, Ph.D., as Head of Business Development. In his role, Dr. Fang will lead Tempest’s global business development efforts, including strategic partnerships, cross-border licensing and corporate transactions, with a particular focus on expanding Tempest’s outreach and partnering efforts in China.
- Announced closing of strategic asset acquisition of new dual-targeting CAR-T assets from Factor Bioscience Inc. and Erigen LLC (“Asset Acquisition”).
- The transaction brought Tempest a portfolio of next-generation CAR-T assets, including TPST-2003, a clinical-stage dual-targeting CD-19/BCMA CAR-T with strategic partner-funded biologics license application (“BLA”) filing in China planned for 2027.
- In March 2026, Tempest announced up to
$6 million private placement (the “2026 Offering”) of common stock and warrants, with$2 million upfront and up to$4 million of potential aggregate gross proceeds upon the exercise in full of warrants, subject to shareholder approval.
Financial Results
First Quarter 2026
- Tempest ended the quarter with
$1.8 million in cash and cash equivalents, compared to$7.7 million on December 31, 2025. The decrease was primarily due to one-time transaction-associated costs incurred prior to or upon closing the Asset Acquisition, offset by net proceeds from the 2026 Offering of$1.7 million . - Net loss and net loss per share for the quarter were
$27.7 million and$2.53 , respectively, compared to$10.9 million and$3.16 , respectively, for the three months ended March 31, 2025. - Research and development expenses for the quarter were
$0.1 million compared to$7.6 million for the three months ended March 31, 2025. The$7.5 million decrease was primarily due to a decrease in costs incurred as a result of re-prioritizing efforts towards exploring strategic alternatives initiated in April 2025 and resulting in the Asset Acquisition completed in February 2026. - General and administrative expenses for the quarter were
$5.4 million compared to$3.3 million for the same period in 2025. The$2.1 million increase was primarily due to one-time costs resulting from the Asset Acquisition completed in February 2026. - Acquired in-process research and development expenses for the quarter were
$22.1 million compared to nil for the three months ended March 31, 2025. Costs incurred prior to or upon closing the Asset Acquisition in the three months ended March 31, 2026 were expensed as acquired in-process research and development.
