Item 2.02

Results of Operations and Financial Condition.

Based upon preliminary estimates and information available to Arcus Biosciences, Inc. (the “Company”) as of October 21, 2026, the Company estimates that it had approximately $694.0 million in cash, cash equivalents and marketable securities as of September 30, 2026. This estimate of its cash, cash equivalents and marketable securities balance is preliminary and subject to completion of the Company’s financial closing procedures, including the completion of management’s reviews. Accordingly, the unaudited preliminary cash, cash equivalents and marketable securities balance set forth above reflects the Company’s preliminary estimate with respect to such information, based on information currently available to management, and may vary from its actual financial position as of September 30, 2026. Further, this preliminary estimate is not a comprehensive statement or estimate of its financial results or financial condition as of September 30, 2026. The unaudited preliminary cash, cash equivalents and marketable securities balance included in this Current Report on Form 8-K has been prepared by, and is the responsibility of, the Company’s management. Ernst & Young LLP, the Company’s independent registered public accounting firm, has not audited, reviewed, examined, compiled, nor applied agreed-upon procedures with respect to the preliminary financial data. Accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto. It is possible that the Company may identify items that require it to make adjustments to the financial information set forth above. This preliminary estimate should not be viewed as a substitute for financial statements prepared in accordance with generally accepted accounting principles in the United States, and it is not necessarily indicative of the balance to be achieved in any future period. Additional information and disclosure would be required for a more complete understanding of the Company’s financial position and results of operations as of September 30, 2026.

The information furnished under this Item 2.02 shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
