Forward-Looking Statements

This

press release includes forward-looking statements that involve risk and uncertainties. Forward-looking statements are any statements

that are not historical facts. Such forward-looking statements, which are based upon the current beliefs and expectations of Lucid Diagnostics’

management, are subject to risks and uncertainties, which could cause actual results to differ from the forward-looking statements. Risks

and uncertainties that may cause such differences include, among other things, volatility in the price of Lucid Diagnostics’ common

stock; general economic and market conditions; the uncertainties inherent in research and development, including the cost and time required

to advance Lucid Diagnostics’ products to regulatory submission; whether regulatory authorities will be satisfied with the design

of and results from Lucid Diagnostics’ clinical and preclinical studies; whether and when Lucid Diagnostics’ products are

cleared by regulatory authorities; market acceptance of Lucid Diagnostics’ products once cleared and commercialized; Lucid Diagnostics’

ability to raise additional funding as needed; and other competitive developments. These factors are difficult or impossible to predict

accurately and many of them are beyond Lucid Diagnostics’ control. In addition, new risks and uncertainties may arise from time

to time and are difficult to predict. For a further list and description of these and other important risks and uncertainties that may

affect Lucid Diagnostics’ future operations, see Part I, Item 1A, “Risk Factors,” in Lucid Diagnostics’ most

recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, as the same may be updated in Part II, Item 1A,

“Risk Factors” in any Quarterly Report on Form 10-Q filed by Lucid Diagnostics after its most recent Annual Report. Lucid

Diagnostics disclaims any intention or obligation to publicly update or revise any forward-looking statement to reflect any change in

its expectations or in events, conditions, or circumstances on which those expectations may be based, or that may affect the likelihood

that actual results will differ from those contained in the forward-looking statements.
