Nature of the Business and Basis of Presentation | 1. Nature of the business and basis of presentation Organization Beam Therapeutics Inc., which we refer to herein as the “Company” or “Beam,” is a biotechnology company committed to establishing the leading, fully integrated platform for precision genetic medicines. Beam’s vision is to provide life-long cures to patients suffering from genetic diseases. The Company was incorporated on January 25, 2017 as a Delaware corporation and began operations in July 2017. Its principal offices are in Cambridge, Massachusetts. Liquidity and capital resources Since its inception, the Company has devoted substantially all of its resources to building its base editing platform and advancing development of its portfolio of programs, establishing and protecting its intellectual property, conducting research and development activities, making arrangements to conduct manufacturing activities with contract manufacturing organizations, organizing and staffing the Company, establishing and maintaining internal manufacturing capabilities, conducting clinical trials, maintaining its facilities and new facility build-outs, business planning, raising capital and providing general and administrative support for these operations. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry including, but not limited to, technical risks associated with the successful research, development and manufacturing of product candidates, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. In March 2025, the Company closed an underwritten public offering of 16,151,686 shares of common stock at a public offering price of $28.48 per share and pre-funded warrants to purchase 1,404,988 shares of common stock at a purchase price of $28.47 per pre-funded warrant for aggregate net proceeds of $470.5 million, after deducting underwriting discounts, commissions and approximately $0.8 million related to legal, accounting and other fees in connection with the offering. Refer to Note 9 for further information. The Company has entered into an at the market sales agreement, or the Sales Agreement, with Jefferies LLC, or Jefferies, pursuant to which the Company is entitled to offer and sell, from time to time at prevailing market prices, shares of its common stock having aggregate gross proceeds of up to $1.1 billion. The Company agreed to pay Jefferies a commission of up to 3.0% of the aggregate gross sale proceeds of any shares sold by Jefferies under the Sales Agreement. As of September 30, 2025, the Company has sold 13,769,001 shares of its common stock under the Sales Agreement at an average price of $62.75 per share for aggregate gross proceeds of $864.0 million, before deducting commissions and offering expenses payable by the Company. There were no shares sold under the Sales Agreement during the three and nine months ended September 30, 2025. Since its inception, the Company has incurred substantial losses and had an accumulated deficit of $1.9 billion as of September 30, 2025. The Company expects to generate operating losses and negative operating cash flows for the foreseeable future. The Company expects that its cash, cash equivalents, and marketable securities as of September 30, 2025 of $1.1 billion will be sufficient to fund its operations for at least the next 12 months from the date of issuance of these financial statements. The Company will need additional financing to support its continuing operations and pursue its growth strategy. Until such time as the Company can generate significant revenue from product sales, if ever, it expects to finance its operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. The Company may be unable to raise additional funds or enter into such other agreements when needed on favorable terms or at all. The inability to raise capital as and when needed would have a negative impact on the Company’s financial condition and its ability to pursue its business strategy. The Company will need to generate significant revenue to achieve profitability, and it may never do so.
