Immunome Inc SEC Filings

Immunome, Inc. is conducting a follow-on public offering of 18,625,000 shares of common stock at $21.50 per share, for expected gross proceeds of approximately $400 million before underwriting discounts, commissions and expenses. All shares are being sold by the company, and the closing is expected on December 18, 2025, subject to customary conditions. The underwriting syndicate is led by Leerink Partners, J.P. Morgan, TD Securities (USA), Goldman Sachs & Co. and Guggenheim Securities, and they have a 30-day option to buy up to an additional 2,793,750 shares at the public offering price, less underwriting discounts and commissions.

Immunome reported positive topline results from its global Phase 3 RINGSIDE trial of varegacestat, an oral, once-daily gamma secretase inhibitor, in patients with progressing desmoid tumors.

The study met its primary endpoint of progression-free survival, cutting the risk of disease progression or death by 84% vs placebo (hazard ratio 0.16; 95% CI 0.071–0.375; p<0.0001). Confirmed objective response rate was 56% with varegacestat versus 9% with placebo, and median best tumor volume change was -83% vs +11% with placebo. All key secondary endpoints, including landmark tumor volume reduction and worst pain intensity, showed statistically significant benefits. Varegacestat was generally well tolerated, though diarrhea, fatigue, rash, nausea and cough were common, and about 55.6% of premenopausal women experienced ovarian toxicity. Immunome plans to present additional RINGSIDE data and submit a New Drug Application to the U.S. Food and Drug Administration in Q2 2026. The company also highlighted preclinical data suggesting its HC74 TOP1 inhibitor ADC payload may offer advantages over existing TOP1 inhibitor payloads.

Immunome, Inc. is offering $400,000,000 of its common stock in a public follow-on offering, and has granted underwriters a 30-day option to purchase up to an additional $60,000,000 of shares at the public offering price, less underwriting discounts and commissions.

The company plans to use the net proceeds, together with existing cash and cash equivalents, to fund the potential commercial launch of varegacestat for desmoid tumors, expand commercial development and manufacturing scale-up for varegacestat, advance clinical and preclinical oncology programs, and for working capital and general corporate purposes. A portion may also be used to in-license, acquire or invest in additional complementary businesses, technologies, products or assets.

As of September 30, 2025, Immunome had 91,706,948 shares of common stock outstanding and historical net tangible book value of $263.9 million, or $2.88 per share. Management estimates that existing cash and cash equivalents, together with the estimated net proceeds from this offering, will be sufficient to fund projected operations into 2028, though buyers face risks such as immediate and future dilution, share price volatility, an existing at-the-market program with $134.1 million capacity remaining, and the company’s intention not to pay cash dividends for the foreseeable future.

Immunome (IMNM) reported Q3 2025 results showing a net loss of $57.5 million as collaboration revenue dropped to zero after its AbbVie agreement terminated in July 2025. Operating expenses rose to $60.1 million, driven by research and development of $49.2 million and general and administrative of $10.9 million.

Cash and cash equivalents were $272.6 million at September 30, 2025, up from $143.4 million at year-end, reflecting a January 2025 public offering and sales under its at-the-market program. Total liabilities were $35.5 million and stockholders’ equity was $263.9 million. The company states its cash is sufficient to fund operations for at least 12 months from the filing date.

Year to date, net loss improved to $142.5 million from $212.7 million in 2024 as in‑process R&D charges subsided. In January 2025, Immunome issued 22,258,064 shares for net proceeds of $161.7 million. During Q3 2025 it sold 4,625,156 shares via ATM for gross proceeds of $45.9 million; $134.1 million capacity remained at quarter end. Common shares outstanding were 91,710,277 as of November 3, 2025. The pipeline advanced with a Phase 3 trial of varegacestat (topline data expected in the second half of 2025) and ongoing early-stage programs.
