Pursuant to Rule 477 under the Securities Act of 1933, as amended (the “Securities Act”), ENDRA Life Sciences Inc. (the “Registrant”) hereby respectfully requests that the Securities and Exchange Commission (the “Commission”) consent to the withdrawal, effective as of the date hereof or at the earliest practicable date hereafter, of the Registrant’s Registration Statement on Form S-1 (File No. 333-288575) filed with the Commission on July 9, 2025, as amended on July 16, 2025, and as further amended on July 25, 2025, together with all exhibits thereto (collectively, the “Registration Statement”).

The Registrant has decided not to pursue the offering due to business decisions and confirms that the Registration Statement has not been declared effective and no securities covered by the Registration Statement have been issued or sold.

Pursuant to Rule 477 under the Securities Act, the Registrant respectfully requests that the Commission grant this application for withdrawal of the Registration Statement effective as of the date hereof or at the earliest practicable date. In accordance with Rule 457(p) under the Securities Act, the Registrant requests that all fees paid to the Commission in connection with the filing of the Registration Statement be credited to the Registrant’s account for future use.
