Protara Therapeutics Raises $75 Million in New Public Offering

TARA
December 05, 2025

Protara Therapeutics, Inc. (Nasdaq: TARA) completed a $75 million public offering of 13,043,479 shares of its common stock at $5.75 per share. The offering, priced under a standard book‑building process, includes an underwriters’ option to purchase an additional 1,956,521 shares, and is expected to close on December 8, 2025.

The net proceeds will be directed toward the clinical development of the company’s lead cell‑therapy candidate TARA‑002, the IV Choline Chloride program, and other pipeline assets, as well as working capital and general corporate purposes. With the new capital, Protara’s cash balance—$133.6 million as of September 30, 2025—will support operations through mid‑2027, extending the company’s runway beyond the current forecast and providing a buffer for upcoming Phase 2 milestones and the planned THRIVE‑3 study of IV Choline Chloride.

TARA‑002 is advancing in non‑muscle invasive bladder cancer and lymphatic malformations, with interim data that have attracted FDA interest for a potential registrational path in BCG‑naïve patients. IV Choline Chloride, which has Fast‑Track designation, is poised to enter the THRIVE‑3 trial, targeting a significant unmet need in patients requiring parenteral support. The capital raise therefore underpins Protara’s strategy to move two high‑potential assets toward regulatory approval and market entry.

The market reacted negatively to the announcement, with the stock falling 17 % in pre‑market trading on December 5 and 12 % in after‑market trading on December 4. The primary driver of the sell‑off was the dilutive effect of issuing 13 million new shares, which immediately reduced existing shareholders’ ownership stakes and EPS expectations. Investors weighed the short‑term dilution against the long‑term value that the new capital could unlock through the accelerated development of TARA‑002 and IV Choline Chloride.

By raising equity rather than debt, Protara preserves a strong balance sheet and avoids interest obligations, positioning the company to pursue future clinical milestones without the pressure of debt covenants. The offering signals management’s confidence in the pipeline’s trajectory and the company’s ability to convert clinical progress into regulatory approvals, while also highlighting the importance of maintaining liquidity in a capital‑intensive biotech environment.
