Organization and Basis of Presentation	1. Organization and Basis of Presentation Cue Biopharma, Inc. (the “Company”) was incorporated in the State of Delaware on December 31, 2014 under the name Imagen Biopharma, Inc., and completed its organization, formation, and initial capitalization activities effective as of January 1, 2015. In October 2016, the Company changed its name to Cue Biopharma, Inc. The Company’s corporate office and research facilities are located in Boston, Massachusetts. The Company is a clinical-stage biopharmaceutical company developing a novel class of injectable biologics designed to selectively engage and modulate tumor-specific T cells within the body to treat a broad range of cancers, chronic infectious diseases, and autoimmune diseases. The Company is in the development stage and has incurred recurring losses and negative cash flows from operations since inception. As of June 30, 2022, the Company had cash and cash equivalents of approximately $66,126,000. Management believes that current cash and cash equivalents on hand at June 30, 2022 are sufficient to fund operations for at least the next twelve months from the date of issuance of these financial statements; however, the future viability of the Company is dependent on its ability to raise additional capital to finance its operations and to fund increased research and development costs in order to seek approval for commercialization of its drug product candidates. The Company’s failure to raise capital as and when needed would have a negative impact on its financial condition and its ability to pursue its business strategies as this capital is necessary for the Company to perform the research and development activities required to develop and commercialize the Company’s drug product candidates in order to generate future revenue streams.
