INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On July 31, 2025, ERAYAK Power Solution Group Inc. (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with certain investors named thereto (the “Purchasers”), pursuant to which the Company agreed to issue and sell, in a registered direct offering (the “Registered Direct Offering”): (i) 32,155,921 class A ordinary shares (the “Class A Ordinary Shares”) of the Company of par value of $0.0001 each (the “Shares”), at a purchase price of $0.065 per share; and (ii) pre-funded warrants to purchase up to 75,536,386 Class A Ordinary Shares (the “Pre-Funded Warrants”) at a purchase price of $0.065 to the purchase price for Shares, less the exercise price of $0.0001 per share. .

The Registered Direct Offering closed on August 1, 2025. The Company received approximately $7 million in gross proceeds from the Registered Direct Offering, before deducting placement agent fees and estimated offering expenses. The Company intends to use the net proceeds from the Registered Direct Offering for its automated warehousing system, product development and certification, sales and marketing and working capital and inventory replenishment.

The Pre-Funded Warrants were sold to the Purchasers, whose purchase of the Shares in the Registered Direct Offering would otherwise have resulted in the Purchasers, together with its affiliates and certain related parties, beneficially owning more than 4.99% of the outstanding share capital of the Company following the consummation of the Registered Direct Offering. Each Pre-Funded Warrant represents the right to purchase one Class A Ordinary Share at an exercise price of $0.0001 per share. The Pre-Funded Warrants are exercisable immediately and may be exercised at any time until the Pre-Funded Warrants are exercised in full (subject to the beneficial ownership limitation described above).

The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties, and termination provisions. Additionally, each of the directors and executive officers of the Company entered into a lock-up agreement, pursuant to which they agreed not to sell or transfer any of the Company securities which they hold, subject to certain customary exceptions, during the six (6) month period following the closing of the Registered Direct Offering.

The Shares, the Pre-Funded Warrants and Placement Agent Warrants, the Class A Ordinary Shares underlying the Pre-funded Warrants and the Placement Agent Warrants were offered by the Company pursuant to a registration statement on Form F-3 (File No.333-278347) (the “Registration Statement”), previously filed and declared effective by the Securities and Exchange Commission (the “Commission”) on May 16, 2024, the base prospectus filed as part of the Registration Statement, and the prospectus supplement dated August 1, 2025 (the “Prospectus Supplement”).

On July 31, 2025, the Company entered into a letter of engagement (the “LOE”) with Craft Capital Management LLC (“Craft” or the “Placement Agent”), pursuant to which the Company engaged Craft as the exclusive placement agent in connection with the Registered Direct Offering. The Placement Agent agreed to use its reasonable best efforts to arrange for the sale of the Shares and the Pre-Funded Warrants. In addition, under the Placement Agency Agreement the Company agreed to pay the Placement Agent a placement agent fee in cash equal to seven percent (6.0%) of the aggregate gross proceeds raised from the sale. The Company also agreed to reimburse the Placement Agent at closing for legal and other expenses incurred by them in connection with the Registered Direct Offering in an amount not to exceed $125,000. In connection with the Offering, the Company also issued, as additional compensation, warrants (the “Placement Agent Warrants”) to Craft Capital Management LLC (the “Placement Agent”) or its designees to purchase an aggregate of up to 6,461,538 Class A Ordinary Shares, being 6% of the aggregate number of the Shares and Pre-funded Warrant Shares (such shares that are issuable from time to time upon exercise of the Placement Agent Warrants (the “Placement Agent Warrant Shares”)). The Placement Agent Warrants are exercisable immediately after issuance and from time to time, in whole or in part, at an exercise price equal to $0.08125, being 125% of the purchase price of each Share, and will expire five (5) years following the closing of the offering.

The foregoing summaries of the Purchase Agreement, the Placement Agent Warrants, and the Pre-Funded Warrants do not purport to be complete and are subject to, and qualified in their entirety by, such documents filed as Exhibits 10.1 4.1 and 4.2, respectively, hereto and incorporated by reference herein. Copies of the press release related to the Registered Direct Offering entitled “Erayak Power Solution Group Inc. Announces $7 Million Registered Direct Offering” and “Erayak Power Solution Group Inc. Announces Closing of $7 Million Registered Direct Offering” are furnished as Exhibit 99.1 and 99.2 hereto and are incorporated by reference herein.

Copies of the opinions of Harney Westwood & Riegels and Ortoli Rosenstadt LLP relating to the legality of the issuance and sale of the Shares and the Pre-Funded Warrants, respectively, are filed as Exhibits 5.1 and 5.2 hereto, respectively.

This Report is incorporated by reference into the registration statements on Form F-3 (File No. 333-278347) of the Company, filed with the Commission, to be a part thereof from the date on which this report is submitted, to the extent not superseded by documents or reports subsequently filed or furnished.

This Report shall not constitute an offer to sell any securities or a solicitation of an offer to buy any securities, nor shall there be any sale of any securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Forward-Looking Statements:

This Report contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 and other Federal securities laws. For example, the Company is using forward-looking statements when it discusses the closing of the Registered Direct Offering. All statements other than statements of historical facts included in this Report are forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company’s current beliefs, expectations and assumptions regarding the future of its business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.

The Company’s actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include the risks and uncertainties described in the Company’s annual report on Form 20-F for the year ended December 31, 2024, filed with the Commission on April 23, 2025, and the Company’s other filings with the Commission. The Company undertakes no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
