Item 1.01 Entry into a Material Definitive Agreement.

Convertible Secured Note Purchase Agreement

On June 24, 2025, Charles & Colvard, Ltd. (the “Company”) entered into a Convertible Secured Note Purchase Agreement (the “Note Purchase Agreement”) with Ethara Capital LLC (the “Holder”), a Delaware limited liability company. In connection with the Note Purchase Agreement, the Company agreed to issue a convertible secured note (the “Note”) to the Holder for an aggregate total purchase price of $2.0 million, to be issued in two tranches: (i) an initial closing in the amount of $500,000 (the “Original Principal Amount”) on or before July 8, 2025 (the “First Closing”), and (ii) a subsequent and final closing of $1.5 million (the “Additional Principal Amount”) on such date as the Company and the Holder thereafter agree, but no later than July 23, 2025 (the “Second Closing,” and together with the First Closing, the “Closings”).

The principal amount on which interest will accrue is equal to the Original Principal Amount as such amount may be (i) increased by payment of PIK Interest (as defined below), (ii) increased by the Additional Principal Amount, and (iii) reduced pursuant to any conversion or redemption effected in accordance with the terms of the Note (such balance from time to time being the “Accreted Principal Amount”). Interest will accrue on the Accreted Principal Amount at an annual rate equal to 5%, payable monthly at the Holder’s discretion in either (i) cash or (ii) an increase in the Accreted Principal Amount by the amount of interest payable (the “PIK Interest”). Subject to obtaining Company shareholder approval first, the Holder may, in its sole discretion, convert all or any portion of the Accreted Principal Amount (plus accrued and unpaid interest) into shares of the Company’s common stock (the “Conversion Shares”) at any time after the issuance of the Note pursuant to its terms. The Accreted Principal Amount, together with any accrued and unpaid interest, shall be due and payable three months following the date the Note is issued (the “Maturity Date”). The Holder may irrevocably elect to extend the Maturity Date for three periods of up to one year each, provided that the Maturity Date cannot be extended later than thirty-nine months following the date the Note is issued. The Second Closing is conditioned on the absence of both an Event of Default and Fundamental Change (each as defined in the Note). The Note is secured by the Company’s Collateral, as defined in the Security Agreement discussed below, but subordinated to the Company’s debt to Wolfspeed, Inc.

The Company agreed to enter into a registration rights agreement relating to the registration for resale of the Conversion Shares within 30 days after the date of the Second Closing. The Note also contains Company restrictive affirmative and negative covenants regarding the operation of its business.

The issuance of the Note was made in reliance upon the exemption provided by Section (4)(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), for the offer and sale of securities not involving a public offering, and Regulation D promulgated under the Securities Act.

Security Agreement

On the date of the First Closing, the Company and the Holder will enter into a security agreement (the “Security Agreement”), granting in favor of the Holder a security interest in all tangible and intangible personal property of the Company. On the date of the Second Closing, the Security Agreement will reflect the Additional Principal Amount.

Director Appointment Rights

In connection with the Note Purchase Agreement, the Holder received the right to appoint two directors to the Company’s board of directors (the “Board”) prior to the date of the First Closing. Upon the Second Closing, the Holder has the right to appoint two observers to the Board.
