Nature of the Business | 1. Nature of the business Kailera Therapeutics, Inc. (the “Company” or “Kailera”) is an advanced clinical-stage biotechnology company focused on elevating the next era of obesity care by advancing a diversified pipeline to provide options for people living with obesity no matter where they are in their treatment journey. The Company was incorporated in May 2024 and is subject to risks and uncertainties common to early-stage companies in the biopharmaceutical industry, including but not limited to, new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations, reliance on third-party organizations for the discovery, manufacturing, clinical support of its product candidates, and the need to obtain additional financing. Product candidates currently under development will require significant additional research and development efforts, including extensive nonclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. There can be no assurance that the Company’s research and development efforts will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its employees and consultants. Through March 31, 2026, the Company has funded its operations primarily with proceeds from the sale and issuance of shares of convertible preferred stock and the issuance of convertible promissory notes, which converted into shares of convertible preferred stock. The Company has incurred losses since its inception, including a net loss of $78.9 million and $18.0 million for the three months ended March 31, 2026 and 2025, respectively. In addition, as of March 31, 2026, the Company had an accumulated deficit of $447.5 million. The Company expects to continue to generate operating losses for the near future. The future viability of the Company is dependent on its ability to raise additional capital to finance its operations. The Company’s inability to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies, and could require it to significantly delay, scale back or discontinue the development and commercialization of one or more of its product candidates. There can be no assurance that the current operating plan will be achieved or that additional funding will be available on terms acceptable to the Company, or at all. The Company believes the cash, cash equivalents and marketable securities on hand of $581.9 million as of March 31, 2026, together with the $718.8 million of gross proceeds raised in its initial public offering subsequent to March 31, 2026, will be sufficient to fund its operations and capital expenditure requirements for at least twelve months from the date these condensed consolidated financial statements are issued.
