1. Nature of Business and Basis of Presentation

Compass Therapeutics, Inc. (“Compass” or the “Company”) is a clinical-stage, oncology-focused biopharmaceutical company developing proprietary antibody-based therapeutics to treat multiple human diseases. The Company’s scientific focus is on the relationship between angiogenesis and the immune system. The pipeline includes novel product candidates that leverage our understanding of the tumor microenvironment, including both angiogenesis-targeted agents and immune-oncology focused agents. These product candidates are designed to optimize critical biological pathways required for an effective anti-tumor response to cancer. These pathways include modulation of the microvasculature via angiogenesis-targeted agents; induction of a potent immune response via activators on effector cells in the tumor microenvironment; and alleviation of immunosuppressive mechanisms used by tumors to evade immune surveillance. The Company plans to advance its product candidates through clinical development as both standalone therapies and in combination with its proprietary drug candidates as long as their continued development is supported by clinical and nonclinical data.  

The Company is subject to risks and uncertainties common to companies in the biotechnology and pharmaceutical industries. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s technology will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. 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.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the financial statements) considered necessary to present fairly the Company’s consolidated financial position as of September 30, 2025 and its consolidated results of operations, comprehensive loss and changes in stockholders’ equity for the three and nine months ended September 30, 2025 and 2024 and cash flows for the nine months ended September 30, 2025 and 2024. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

The unaudited condensed consolidated financial statements include the accounts of Compass Therapeutics, Inc. and its subsidiaries, and have been prepared by the Company in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet at December 31, 2024 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Annual Report”).

Liquidity

Since inception, the Company has devoted substantially all of its efforts to organizing and staffing, business planning, raising capital, research and development activities, building its intellectual property portfolio and providing general and administrative support for these operations. The Company has funded its operations with proceeds from the sale of equity securities and borrowing from debt arrangements. Through September 30, 2025, the Company has received $568 million in gross proceeds from the sale of equity securities. As of September 30, 2025, we had cash, cash equivalents and marketable securities of $220 million. Based on our research and development plans, we expect that such cash resources will enable us to fund our operating expenses and capital expenditure requirements into 2028.
