6. Commitments and Contingencies

Clinical Trials

During the first quarter of 2025, the Company announced top-line results from a Phase 3 STAR-1 clinical trial of XYNGARI™, formerly its lead prescription candidate for the treatment of moderate-to-severe acne. The total contract amount with the clinical research organization was approximately $7.0 million, and the contract extended from the fourth quarter of 2023 to the first half of 2025. During the quarter ended March 31, 2025, the Company recognized $0.7 million in research and development expense related to the clinical research organization for the STAR-1 trial. No additional expense was incurred during the quarter ended March 31, 2026.

Supplier Agreement

On February 27, 2020, the Company entered into an exclusive Supply Agreement (“Supplier Agreement”) with Reka-Farm, LLC (“Reka-Farm”), whereby Reka-Farm will supply the Company with the Spongilla raw materials necessary for use in the development of our products. The Supplier Agreement has an indefinite term unless and until terminated. The Supplier Agreement may be terminated (i) by either party for material breach with 90 days written notice, if such material breach is not cured within such notice period and (ii) by the Company for any reason or no reason upon 90 days written notice to Reka-Farm. For the term of the Supplier Agreement, Reka-Farm is prohibited from supplying Spongilla for development and sale of any other product outside of the Russian Federation, other than Cosmetic Products (as defined in the Supplier Agreement). Pursuant to the Supplier Agreement, the Company pays a pre-negotiated price per kilogram for Spongilla supplied by Reka-Farm, and the Company is required to pay to Reka-Farm a royalty payment of less than one percent of the Net Sales (as defined in the Supplier Agreement) of any products we develop containing Spongilla raw material supplied by Reka-Farm.

As a result of Russia’s invasion of Ukraine, the United States, the United Kingdom, and the European Union governments, among others, have developed coordinated sanctions and export-control measure packages against Russian individuals and entities. The Company is currently a party to an exclusive Supplier Agreement for the supply of the Spongilla raw material used in the Company’s Tome skincare brand. The counterparty to this supply agreement, Reka-Farm, is a Russian entity. The imposition of enhanced export controls and economic sanctions on transactions with Russia and Russian entities by the United States, the United Kingdom, and/or the European Union could prevent the Company from performing under this existing contract or any future contract it may enter or may prevent the Company from remitting payment for raw material purchased from the Company’s supplier. The Company has recently received a shipment of raw material from its supplier after the implementation of export controls and sanctions, containing additional quantities of Spongilla raw material, which the Company believes will provide the Company with sufficient quantities of Spongilla to support the planned launch and sale of the Tome skincare products, based on current assumptions. The Company plans to order additional shipments of raw materials to support the commercial sales of its products, the timing of which is unknown. Depending on the extent and breadth of new sanctions or export controls that may be imposed against Russia, otherwise or as a result of the impact of the war in Ukraine, it is possible that the Company’s ability to obtain additional supply of the Spongilla raw material used in Tome skincare could be negatively impacted, which could adversely affect its business, results of operations, and financial condition.

Reka-Farm is the sole supplier of the Company’s Spongilla raw materials used in its skincare products. The Company has evaluated other suppliers of Spongilla from other regions of the world; however, no other supplier nor their Spongilla supply has met the quality standards set forth by the Company’s cGMP practices. An alternative source to supply Spongilla raw materials could be the aquaculture of Spongilla in a lab setting, which could significantly increase the cost of raw materials as well as the availability of raw materials due to the cost and time to develop and build an aquaculture infrastructure to supply Spongilla in commercial quantities. If Reka-Farm is unavailable to supply Spongilla raw materials to the Company, it could adversely affect its business, results of operations, and financial condition.

Collaboration Agreement

On January 17, 2025, the Company entered into a Clinical Trial Collaboration Agreement (the “Clinical Trial Agreement”) with Revance Therapeutics, Inc. (“Revance”), pursuant to which the Company and Revance intend to conduct a multi-center clinical trial (the “Trial”) to evaluate the topical application of Dermata Compound, the Company’s topical Spongilla powder (formerly referred to as DMT310 or XYNGARI), with Daxxify (daxibotulinumtoxinA-lanm), Revance’s botulinum toxin type A. Pursuant to the terms of the Clinical Trial Agreement, Revance has granted the Company a non-exclusive, worldwide, non-transferable, royalty-free license, with a right to sublicense (subject to limitations), to use certain Revance intellectual property, solely as necessary or useful for the Company to conduct the trial under the Clinical Trial Agreement. The Company has granted Revance a similar license to use Dermata Compound and other compound(s) under the Clinical Trial Agreement. The Clinical Trial Agreement will terminate upon completion of the Trial, the delivery of the data resulting from the Trial and the completion of any statistical analyses of the data resulting from the Trial. Either party may terminate the Clinical Trial Agreement upon a material breach by the other party that remains uncured following 30 days after the date of written notice of such breach. In addition, either party may terminate the Clinical Trial Agreement immediately upon written notice if such party reasonably deems it necessary in order to protect the safety, health or welfare of subjects enrolled in the Trial. The Company has agreed to sponsor, conduct, and fund the Phase 2a clinical trial, but no financial obligations or consideration is contemplated in the Clinical Trial Agreement, and the Company has placed the Phase 2a clinical trial on hold at this time.

License Agreements

On March 31, 2017, the Company entered into a license agreement, as amended (the “License Agreement”) with Villani, Inc. (“Villani”) whereby Villani granted the Company an exclusive, sub-licensable, royalty-bearing license (the “License”) under the Licensed Patents (as defined in the License Agreement), to formulate, develop, seek regulatory approval for, make or sell products that contained Spongilla lacustris (alone or in combination with other active or inactive ingredients) for the treatment of diseases, disorders and conditions of the skin, including but not limited to acne, rosacea, psoriasis, atopic dermatitis, seborrheic dermatitis, actinic keratosis and eczema that were developed using certain licensed know-how (“Licensed Products”). The Company was responsible for the development (including manufacturing, packaging, non-clinical studies, clinical trials and obtaining regulatory approval and commercialization (including marketing, promotion, distribution, etc.)) for all Licensed Products. The original License Agreement was amended in 2019, and pursuant to the amended License Agreement, the Company was required to make future milestone payments to Villani in an aggregate amount of up to $20.25 million upon the achievement of specified development and sales milestones, payable in cash or in equity, at the option of Villani, as well as single-digit royalty payments on net sales. On July 30, 2021, the Company further amended the License Agreement in the Second Amendment to the License and Settlement Agreement (the “Second Amendment”). Pursuant to the Second Amendment, the Company was required to make future milestone payments to Villani in an aggregate amount of up to $40.5 million upon the achievement of specified development and sales milestones, payable in cash or in equity, at the option of Villani, as well as single-digit royalty payments on net sales. The Second Amendment includes customary terms relating to, among others, indemnification, intellectual property protection, confidentiality, remedies, and warranties.

On November 10, 2025, the Company received a notice of material breach and demand for cure (the “Notice”) from Villani alleging that the Company breached the License Agreement as a result of the Company’s recent strategic shift to focus on DTC skincare products. The Notice alleged that the Company (i) failed to use Commercially Reasonable Efforts (as defined in the License Agreement) to pursue a prescription product business, (ii) failed to provide Villani with advance notice of certain submissions to regulatory authorities, (iii) used Licensed Know-How (as defined in the License Agreement) outside of the Field (as defined in the License Agreement) and (iv) the Company’s anticipated OTC kits did not qualify as Licensed Products (as defined in the License Agreement). On November 11, 2025, Villani delivered an additional notice to the Company (the “Additional Notice”) whereby Villani requested (i) the reversion and assignment of all assets regarding Spongilla-based products back to Villani, (ii) that the Company preserve all Spongilla inventory, and (iii) the Company preserve all documents, data, and tangible materials related to Spongilla. The Company disputes the allegations contained in the Notice and the Additional Notice. As part of the Company’s strategic pivot in September 2025, on November 17, 2025, the Company provided notice to terminate the License Agreement with an effective date of February 15, 2026. As of March 31, 2026, the Company has not accrued any payments related to the Villani Notices since the Company does not believe any financial payments are probable and all obligations under the termination of the License Agreement have been fulfilled. The termination of the License Agreement was effective February 15, 2026 and the Company believes it has fulfilled its obligations under the termination provisions of the License Agreement. See related additional disclosures under Legal Proceedings disclosure below.

Legal Proceedings

On April 23, 2026, Dermata was served with a complaint filed by Villani, Inc. (“Villani”) in the U.S. District Court for the Central District of California (“Lawsuit”). The Lawsuit alleges the Company made false or misleading advertising statements under the Lanham Act 15 USC §1125, breach of contract, and conversion, and seeks injunctive relief. In connection with the Lawsuit, on April 26, 2026, Villani filed a motion seeking a temporary restraining order (“TRO”) and a preliminary injunction. The Company denies the allegations in the Lawsuit and is vigorously opposing Villani’s motion.

On May 6, 2026, the court denied the TRO in part as related to Villani’s breach of contract and conversion claims, and granted the TRO in part as related to certain of Villani’s false or misleading advertising claims, which imposes certain temporary restrictions on specific statements the Company can make, pending further proceedings. The preliminary injunction, if granted, could extend certain of the above restrictions. A hearing on the preliminary injunction is scheduled for July 14, 2026.

At this time, the Company is unable to reasonably estimate the likelihood of an unfavorable outcome or the amount or range of potential loss, if any, that may result from this matter. The TRO and any potential preliminary injunction could have an adverse impact on the Company’s operations, financial condition, and results of operations, particularly if the restrictions remain in place for an extended period or are expanded in scope.

The Company will continue to monitor developments in this matter and will adjust its disclosures as appropriate.

Registration Rights Agreements

In connection with the January 2025 Private Placement, the Company entered into a registration rights agreement with the purchasers, dated as of January 21, 2025, (the “January 2025 Registration Rights Agreement”). The January 2025 Registration Rights Agreement provided that the Company shall file a registration statement covering the resale of all of the registrable securities with the SEC. The registration statement on Form S-3 required under the Registration Rights Agreement was filed with the SEC on January 30, 2025, and became effective on February 5, 2025.

In connection with the December 2025 Private Placement, the Company entered into a registration rights agreement with the purchasers, dated as of December 23, 2025, (the “December 2025 Registration Rights Agreement”). The December 2025 Registration Rights Agreement provided that the Company shall file a registration statement covering the resale of all of the registrable securities with the SEC. The registration statement on Form S-3 required under the December 2025 Registration Rights Agreement was filed with the SEC on January 22, 2026, and became effective on January 29, 2026.

Upon the occurrence of any Event as defined in the January 2025 Registration Rights Agreement and the December 2025 Registration Rights Agreement, which, among others, prohibits the purchasers from reselling the securities for more than ten consecutive calendar days or more than an aggregate of fifteen calendar days during any 12-month period, and should the registration statement cease to remain continuously effective, the Company would be obligated to pay to each purchaser, on each monthly anniversary of each such Event, an amount in cash, as partial liquidated damages and not as a penalty, equal to the product of 2.0% multiplied by the aggregate subscription amount paid by such purchaser in the Private Placement, up to a maximum of 12% of the aggregate subscription amount. As of March 31, 2026, the Company determined that the likelihood of the Company incurring a significant amount of liquidated damages pursuant to the Registration Rights Agreements is remote.
