INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On August 19, 2026, Nexus Advanced Technologies Inc. (formerly K Wave Media LTD, hereafter the “Company”) entered into a placement agency agreement (the “Placement Agency Agreement”) with D. Boral Capital LLC (“D. Boral” or the “Placement Agent”), relating to the sale of 526,314 of the Company’s ordinary shares, par value $0.003 per share (the “Ordinary Shares”), directly to certain institutional investors at a price of $1.90 per Ordinary Share. D. Boral agreed to act as the exclusive placement agent in connection with this registered direct offering (the “Registered Direct Offering”).

The Registered Direct Offering closed on August 20, 2026. The Company received gross proceeds of approximately $1,000,000 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 general corporate purposes, which may include, but are not limited to, working capital, acquisitions of potential business targets and general and administrative expenses. The Ordinary Shares were offered by the Company pursuant to a registration statement on Form F-3 (File No. 333-297167) (the “Registration Statement”), previously filed and declared effective by the U.S. Securities and Exchange Commission (the “Commission”) on July 9, 2026, the base prospectus filed as part of the Registration Statement, and the prospectus supplement dated August 20, 2026 (the “Prospectus Supplement”).

Under the Placement Agency Agreement, the Company agreed to pay the Placement Agent a placement agent fee in cash equal to seven percent (7.0%) of the aggregate gross proceeds raised from the sale of the Ordinary Shares. The Company also agreed to reimburse the Placement Agent for certain specified expenses, including the fees and disbursements of its legal counsel, in an amount not to exceed $75,000 (excluding reimbursable fees and expenses of third-party providers). The Company also agreed to provide indemnification and contribution to the Placement Agent with respect to certain liabilities, including liabilities arising out of or in connection with the transactions contemplated by the Placement Agency Agreement.

The foregoing summaries of the Placement Agency Agreement and the Securities Purchase Agreement do not purport to be complete and are subject to, and qualified in its entirety by, such documents filed as Exhibits 10.1 and 10.2 hereto and incorporated by reference herein. A copy of the press release related to the Registered Direct Offering entitled “K Wave Media LTD Announces Pricing of Registered Direct Offering” is furnished as Exhibit 99.1 hereto and is incorporated by reference herein.

Copies of the opinions of Maples and Calder (Cayman) LLP and Duane Morris LLP relating to the legality of the issuance and sale of the Ordinary Shares are filed as Exhibits 5.1 and 5.2 hereto, respectively.

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.

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.
