Forward-Looking Statements

Statements in this press release that are not statements of historical fact are forward-looking statements for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The press release, in some cases, uses terms such as “anticipate,” “believe,” “could,” “expect,” “plan,” “will,” or other words that convey uncertainty of future events or outcomes to identify these forward-looking statements. Forward-looking statements include statements regarding Kronos Bio’s intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things, the next clinical update on KB-0742; our expected completion of IND-enabling studies and the timing thereof for KB-9558; our expected clinical trial for KB-9558 and the timeline for dosing the first patients; future pipeline development activities or outcomes; the potential of Kronos Bio’s product candidates; Kronos Bio’s expected cash runway; and other statements that are not historical fact. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, including, without limitation: risks associated with changes to the assumptions underlying estimated expenses and savings; changes in the macroeconomic environment or competitive landscape that impact Kronos Bio’s business; risks associated with completing necessary preclinical studies and receiving regulatory clearance for, and enrolling, clinical trials; whether Kronos Bio will be able to progress its clinical trials on the timelines anticipated, including due to risks inherent in the clinical development of novel therapeutics; risks related to Kronos Bio’s limited experience as a company in conducting clinical trials; the risk that results of preclinical studies and early clinical trials (including

preliminary results) are not necessarily predictive of future results; and risks associated with the sufficiency of Kronos Bio’s cash resources and need for additional capital. These and other risks are described in greater detail in Kronos Bio’s filings with the Securities and Exchange Commission (SEC), including under the heading “Risk Factors” in its Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 21, 2024, and in its Quarterly Report on Form 10-Q for the quarter ended March 21, 2024, being filed with the SEC today.
