ITEM 1.01 Entry into a Material Definitive Agreement

On August 8, 2025, Sigyn Therapeutics, Inc. (the “Company”) entered into a Convertible Note Purchase Agreement (the “Purchase Agreement”) with Lambda Venture Partners, LLC, pursuant to which the Company may issue and sell, subject to the terms of the Purchase Agreement, up to $550,000 in aggregate principal amount of one-year 8% convertible promissory notes (the “Notes”) in exchange for $500,000. The Notes are convertible, at the option of the holder, into shares of the Company’s common stock at a conversion price equal to a 35% discount to the lowest traded price of the Company’s common shares during the ten (10) trading days immediately prior to the date on the notice of conversion. The issuances of the foregoing securities are exempt from registration pursuant to Section 4(a)(2) of the Securities Act promulgated thereunder as the Sellers are sophisticated investors and familiar with the Company’s operations. No stock purchase warrants were issued as part of the agreement.

On August 11, 2025, the Company issued the first tranche of Notes in the aggregate principal amount of $110,000 to Lambda Venture Partners, LLC, and received $100,000 in proceeds, consistent with the Purchase Agreement.

The foregoing description of the Purchase Agreement and the Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, the Form of Convertible Note, and any related documentation, copies of which will be filed as exhibits to the Current Report on Form 8-K and are incorporated herein by reference.

On August 7, 2025, Christopher Wetzel notified the Company of his decision to resign from the Board of Directors, effective August 7, 2025.

The discontinuation of coverage was not related to any specific claim or proceeding against the Company or its directors or officers.
