CURRENT REPORT

On June 2, 2026, Sensus Healthcare, Inc. (the “Company”) entered into a Loan Agreement (the “Loan Agreement”) with City National Bank of Florida (“CNB”) pursuant to which CNB has made available to the Company a revolving credit facility providing for maximum borrowings of $15,000,000 (the “Loan”), which is evidenced by a Revolving Promissory Note, dated June 2, 2026 (the “Note”), made by the Company in favor of CNB. Pursuant to the terms of the Note, advances made under the Loan bear interest at the Secured Overnight Financing Rate plus 3% per annum and have a maturity date of June 5, 2027 unless extended by mutual agreement of the Company and CNB. Pursuant to a Pledged Collateral and Restricted Account Agreement, dated June 2, 2026 (the “Pledged Collateral Agreement”), between the Company and CNB, the Loan is secured by cash collateral in the amount of $2,230,000, and pursuant to a Security Agreement, dated June 2, 2026 (the “Security Agreement”), between the Company and CNB, the Loan is secured by a security interest in all of the Company’s assets (the “Collateral”).

Under the Loan Agreement, the Company must obtain CNB’s prior written consent in order to take any of the following actions: (a) sell or transfer any of the Company’s assets outside the ordinary course of its business; (b) incur, create, assume, or permit to exist any other indebtedness (subject to certain exceptions); (c) encumber any of the Company’s assets with any liens other than liens in favor of CNB and certain other permitted liens, or (d) remove the Company’s current Chief Executive Officer, President or Chief Financial Officer. The Loan Agreement contains a financial covenant requiring that the Company maintain a minimum debt service coverage ratio of 1.50. The Loan Agreement also contains customary representations and warranties and customary events of default, upon the occurrence of which, after any applicable grace period, CNB would have the ability to accelerate all outstanding advances, terminate the Loan, and exercise remedies with respect to the Collateral.

This description of the Loan Agreement, Note, Pledged Collateral Agreement, and Security Agreement is qualified in its entirety by reference to the Loan Agreement, Note, Pledged Collateral Agreement, and Security Agreement, which are attached as Exhibits 10.1, 10.2, 10.3, and 10.4, respectively.

As previously reported, the Company’s previous revolving credit facility, made available to the Company by Fifth Third Bank, N.A., as successor to Comerica Bank, has been terminated.

(d) Exhibits.
