CAMBRIDGE, Mass.—(GLOBAL NEWSWIRE)—December 4, 2020—Foghorn Therapeutics Inc. (Nasdaq: FHTX), a company pioneering the discovery and development of a new class of medicines targeting genetically determined dependencies within the chromatin regulatory system, today reported financial results for the third quarter ended September 30, 2020 and provided a corporate update.

In addition, our first degrader program, FHD-609, remains on track for an IND filing in the first half of next year.

In November 2020, the underwriters exercised their option to purchase an additional 951,837 shares of common stock at the public offering price. The gross proceeds of the offering, before deducting underwriting discounts and commissions and other offering expenses payable by Foghorn, were $135.2 million.

Key Upcoming Milestones

• FHD-286 IND submission expected by year end 2020: FHD-286, a highly potent, selective, allosteric, orally available small molecule enzymatic inhibitor is initially being

developed in acute myelogenous leukemia and uveal melanoma. The company remains on track to submit an Investigational New Drug (IND) to the FDA by year end.

• FHD-609 IND submission expected in the first half of 2021: FHD-609, a highly potent, selective, intravenous, small molecule protein degrader of BRD9 is initially being developed for the treatment of synovial sarcoma with the intention to expand into indications beyond synovial sarcoma, including SMARCB1-deleted tumors.

Third Quarter 2020 Financial Results

• Cash Position and Financial Guidance: Cash and cash equivalents as of September 30, 2020 were $74.6 million, compared to $15.0 million as of December 31, 2019. The September 30, 2020 cash and equivalents excludes $122.2 million in net proceeds from our initial public offering, which was completed in October 2020.

• Revenues: Collaboration revenues for the third quarter of 2020 were $0.2 million, compared to no revenue for the third quarter of 2019, which reflects revenue recognized under our research collaboration agreement with Merck which was entered into in July 2020.

• Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2020 were $16.1 million, compared to $11.3 million for the third quarter of 2019. The increase in R&D expenses was primarily attributable to higher preclinical costs related to our first two programs and increased personnel to support our research and development activities.

• General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2020 were $2.6 million, compared to $1.8 million for the third quarter of 2019. The increase in G&A expenses was primarily attributable to an increase in headcount in our general and administrative functions to support our business.

• Net Loss: Net loss attributable to common stockholders was $18.4 million, or $3.12 per share, for the quarter ended September 30, 2020, compared to $13.1 million, or $3.05 per share, for the quarter ended September 30, 2019.
