Amendment to Credit Agreement

As previously disclosed, on November 14, 2025, Milk Makeup LLC, a Delaware limited liability company (“Milk Makeup”) and Obagi Cosmeceuticals LLC, a Delaware limited liability company (“Obagi Cosmeceuticals”, and together with Milk Makeup, the “Borrowers”), which are wholly owned subsidiaries of Waldencast plc, a public limited company incorporated in Jersey (the “Company”), entered into the Credit Agreement (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among the Borrowers, the Company, LSSF II Offshore Investments, LP, an Ontario limited partnership acting by its general partner, Lumina Fund II GP Ltd. (in such capacity, the “Administrative Agent”) and the lenders party thereto (the “Lenders”). The Credit Agreement requires the Company to issue warrants to the Lenders that hold Term Tranche B Loans (as defined in the Credit Agreement) to purchase up to 1,000 ordinary shares of the Company per $1,000 principal amount of Term Tranche B Loans then outstanding (the “Warrants”). On June 11, 2026, the Borrowers have entered into the Second Amendment to Credit Agreement and Acknowledgement (the “Second Amendment”) with the Administrative Agent and the Lenders to, among other things, postpone the requirement for the Company to issue the Warrants from (x) on or prior to July 1, 2026 to (b) on or prior to November 17, 2026.

The foregoing description of the Second Amendment and the transactions contemplated thereby is not complete and is subject to, and qualified in its entirety by, the full text of the Second Amendment, a copy of which is filed as Exhibit 10.1 hereto and is expressly incorporated by reference herein.

Approval of saypha® ChIQ™

On June 15, 2026, the Company issued an announcement titled “Obagi Medical Announces FDA Approval of Obagi® saypha® ChIQ™ Injectable Hyaluronic Acid Gel”, a copy of which is attached as Exhibit 99.2 to this Form 6-K.

The information in this report on Form 6-K (including Exhibits 10.1 and 99.2 hereto) (“Report”) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Forward-Looking Statements

This press release contains certain forward-looking statements within the meaning of the federal securities laws, including statements regarding the planned launch of Saypha® ChIQ™ and the growth strategies of Obagi Medical. These forward-looking statements generally are identified by the words “estimates,” “projects,” “expects,” “anticipates,” “forecasts,” “plans,” “intends,” “believes,” “seeks,” “may,” “will,” “would,” “should,” “future,” “propose,” “target,” “goal,” “objective,” “outlook” and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside the control of Waldencast and Obagi Medical that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Important factors, among others, that may affect actual results or outcomes include, but are not limited to: (i) the success of any commercial launches, (ii) the general impact of geopolitical events, including the impact of current wars, conflicts and other hostilities, (iii) the overall economic and market conditions, sales forecasts and other information about Waldencast’s possible or assumed future results of operations or our performance, (iv) changes in general economic conditions, (v) the impact of any international trade or foreign exchange restrictions, the imposition of new or increased tariffs, foreign currency exchange fluctuations, (vi) that the price of Waldencast’s securities may be volatile due to a variety of factors, including Waldencast’s or Obagi Medical’s inability to implement their business plans, and (vii) the ability to continue to innovate Obagi Medical’s existing products and anticipate and respond to market trends and changes in consumer preferences. The foregoing list of factors is not exhaustive.

looking statements. Forward-looking statements speak only as of the date they are made.
