Tempest Therapeutics, Inc. (TPST) is a clinical-stage biotechnology company headquartered in Brisbane, California, focused on developing next-generation in vivo CAR-T therapies for oncology and autoimmune disease. The company's lead program, TPST-4003, combines a dual-targeting CD19/BCMA CAR structure with a proprietary CD7-targeted mRNA/LNP delivery system intended to enable broad "immune reset" across multiple indications. Tempest also continues to advance TPST-2003, a dual-targeting CD19/BCMA CAR-T therapy being evaluated in relapsed/refractory multiple myeloma through partner-sponsored trials.
Because Tempest is pre-revenue and relies heavily on equity financings and strategic partnerships, investors follow the stock closely for clinical data readouts, partnership announcements, and balance-sheet updates rather than traditional earnings metrics. I checked some of the sector comparisons using Tickeron’s AI Screener to see how TPST stacks up against peers.
Over the last 30 days, TPST declined approximately 51%, moving from a closing price near $0.77 in early October to about $0.38 by early November. The move was not linear: the stock briefly firmed in late September before a steady slide through October that accelerated into November.
The quarterly picture is even steeper. From mid-August levels of roughly $1.00 to $1.10, the stock has fallen more than 60%, reflecting sustained selling pressure that followed an outsized but short-lived rally in mid-September.
The most significant near-term pressure came from financing and listing concerns. On November 4, 2026, Tempest disclosed that Nasdaq had issued a minimum bid price deficiency notice because the stock had closed below $1.00 for 30 consecutive business days. The notice has no immediate effect on the listing, and the company has until May 3, 2027 to regain compliance, but it underscored the market's concerns about the company's capital position and potential dilution.
Leadership changes also contributed to uncertainty. In late October, Tempest announced that Chief Financial Officer Constance Ames resigned for personal reasons, with the board appointing Stephanie Horn-Warnock as CFO effective immediately. The rapid finance-function transition arrived at a time when investors were already focused on the company's liquidity and runway.
These developments followed September's dramatic volatility. On September 16, the stock surged on very heavy volume after Tempest announced an exclusive option agreement with Hebei Senlang Biotechnology related to its in vivo CAR-T platform, and later that month it signed a related-party Master Services Agreement with Factor Bioscience covering research and development services. The gains quickly faded, however, as profit-taking and broader concerns about share structure and dilution took hold. I also reviewed the volume patterns here with Tickeron’s AI Pattern Search Engine for additional context.
The quarterly decline reflects a larger narrative of a small, pre-revenue biotech navigating capital constraints while advancing an early-stage pipeline. After the February 2026 asset acquisition from Factor Bioscience and Erigen LLC brought in new CAR-T assets, Tempest has focused on disciplined capital deployment and partnerships to fund development. However, the company ended recent quarters with modest cash balances, leaving it dependent on additional financings that can pressure the share price.
Corporate-governance friction also played a role. Tempest repeatedly adjourned and reconvened a special stockholder meeting through mid-October seeking approval to amend its charter and permit stockholder action by written consent, a process that highlighted an evolving shareholder base and voting dynamics. Combined with the Nasdaq deficiency notice, these factors have kept sentiment subdued even as the company works toward first-in-human milestones for TPST-4003.
Looking ahead, investors should monitor several factors. First is the company's path back to Nasdaq compliance, including any capital-raising activity that could affect the share count and price. Second, pipeline progress for TPST-4003, including planned first-in-human dosing and initial clinical data expectations, and continued TPST-2003 development toward a potentially registrational study in multiple myeloma will be key catalysts. Third, quarterly financial disclosures will be scrutinized for cash balance, runway, and any new partnership or licensing announcements. Finally, broader biotech financing conditions and sector sentiment will likely influence a stock that remains highly sensitive to liquidity and dilution dynamics.
