Terns Pharmaceuticals Seeks $300M in Mixed Shelf Offering Amid Pipeline Milestones

Terns Pharmaceuticals (NASDAQ: TERN) has filed a new mixed shelf offering with the SEC, seeking to raise up to $300 million to fuel its oncology and obesity-focused pipeline. The move comes as the company prepares for critical clinical readouts in late 2025, with its lead candidates TERN-701 (for chronic myeloid leukemia) and TERN-601 (for obesity) nearing pivotal milestones. The filing, detailed in a May 8, 2025 Form S-3 registration statement, underscores Terns’ strategic focus on advancing its small-molecule therapies while maintaining financial flexibility.

The Offering’s Flexibility and Purpose

The $300 million shelf offering marks a significant expansion from Terns’ prior 2023 shelf (File No. 333-269508), which raised $172.7 million in 2024 to fund early-stage trials. This new shelf allows Terns to sell a mix of securities—including common stock, preferred stock, and debt—in tailored tranches, depending on market conditions. Unlike the 2024 offering, which focused solely on common shares and pre-funded warrants, the 2025 shelf offers greater flexibility to optimize capital costs.

The proceeds will primarily fund:
- TERN-701: A next-generation BCR-ABL inhibitor for CML, with 6-month major molecular response (MMR) data expected in Q4 2025.
- TERN-601: A GLP-1 receptor agonist for obesity, targeting 12-week weight loss results in the same quarter.
- Manufacturing and preclinical programs, including the TERN-800 series (GIPR antagonist) and TERN-501 (THR-β agonist).

Financial Position and Runway

As of March 31, 2025, Terns reported $334.3 million in cash, cash equivalents, and marketable securities—a slight dip from $358.2 million at year-end 2024. The company projects this capital to support operations into 2028, assuming no major new expenditures.

While Terns’ Q1 2025 net loss widened to $23.9 million (vs. $22.4 million in Q1 2024), R&D expenses remained stable at $18.7 million, reflecting disciplined spending. Analysts note that the $300 million shelf, if fully utilized, would extend the cash runway further, potentially through 2029 or beyond.

Pipeline Progress and Risks

TERN-701 (CML):

• Phase 1 CARDINAL Trial: Dose expansion is underway, with 80 patients randomized to 320 mg or 500 mg cohorts.
• Key Data: 6-month MMR results in Q4 2025 will determine if TERN-701 can advance to pivotal trials. Early safety data (no dose-limiting toxicities) suggests a favorable profile compared to existing therapies like asciminib.

TERN-601 (Obesity):

• Phase 2 FALCON Trial: Enrolling obese patients to assess 12-week weight loss. Phase 1 results showed 5.5% weight loss at 750 mg, with rapid titration.
• Competitive Edge: TERN-601 aims to offer oral administration and simpler dosing than injectable GLP-1 agonists like semaglutide.

Other Programs:

• TERN-800 Series: GIPR antagonist discovery aims to pair with GLP-1 therapies for synergistic weight loss.
• TERN-501: A thyroid hormone beta agonist targeting metabolic liver disease.

Risks and Challenges

• Clinical Uncertainty: If TERN-701’s MMR data or TERN-601’s weight loss results fall short of expectations, the stock could face pressure.
• Regulatory Hurdles: Even with positive data, delays in FDA approval timelines or manufacturing challenges could disrupt timelines.
• Market Competition: Obesity is a crowded space, with rivals like Novo Nordisk (NVO) and Eli Lilly (LLY) dominating GLP-1 agonist markets.

Analyst and Investor Outlook

Analysts project Terns’ net loss per share to narrow slightly in 2026, but the company’s valuation hinges on Q4’s readouts. Consensus estimates as of May 2025 suggest a price target of $34.00, implying nearly a 10x jump from its May 8 closing price of $3.39.

Conclusion

Terns’ $300 million mixed shelf offering is a strategic move to capitalize on its advancing pipeline, particularly with Q4’s dual data readouts. The flexibility of the shelf—allowing debt or equity tranches—positions the company to navigate market volatility while funding late-stage trials.

Crucially, TERN-701’s potential in CML and TERN-601’s oral obesity profile address significant unmet needs. If both candidates deliver positive data, Terns could pivot from a pre-commercial biotech to a contender in two multibillion-dollar markets. However, investors must weigh the risks: a single misstep in clinical trials could derail this trajectory.

With $334 million in cash and a 2028 runway, Terns has time to execute—but the next six months will be make-or-break. The stock’s valuation, currently at a fraction of its potential, makes it a high-risk, high-reward bet for investors willing to bet on clinical success. The coming months will test whether Terns’ pipeline can deliver the returns its latest capital raise implies.
