11. Commitments and Contingencies

Product Development Agreement

In February 2013, Scilex Pharma became a party to a product development agreement (as amended, the “Product Development Agreement”) with Itochu and Oishi (together, the “Developers”), pursuant to which the Developers will manufacture and supply lidocaine tape products, including ZTlido and SP-103 (the “Products”), for Scilex Pharma. The Developers initially developed and have intellectual property rights relating to the Products. Pursuant to the Product Development Agreement, Scilex Pharma acquired an exclusive right to develop and commercialize the Products worldwide except for Japan. The Developers are responsible for sourcing and supplying lidocaine for development and commercialization purposes.

Pursuant to the Product Development Agreement, Scilex Pharma is required to make aggregate royalty payments between 25% and 35% to the Developers based on net profits. Scilex Pharma made royalty payments in the amount of $0.6 million and $2.0 million for the three months ended June 30, 2025 and 2024, respectively, and $1.9 million and $4.4 million for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025 and December 31, 2024, Scilex Pharma had ending balances of accrued royalty payables of $4.5 million and $4.0 million, respectively. Total royalty expense recorded within cost of revenue was $1.6 million and $2.4 million for the three months ended June 30, 2025 and 2024, respectively, and $2.3 million and $4.7 million for the six months ended June 30, 2025 and 2024, respectively.

Net profits are defined as net sales, less cost of goods and marketing expenses. Net sales are defined as total gross sales of any Product, less all applicable deductions, to the extent accrued, paid or allowed in the ordinary course of business with respect to the sale of such Product, and to the extent that they are in accordance with GAAP. If Scilex Pharma were to sublicense the licensed technologies, the Developers will receive the same proportion of any sublicensing fees received therefrom. The Product Development Agreement will continue in full force and effect until October 2, 2028, the date that is ten years from the date of the first commercial sale of ZTlido. The Product Development Agreement will renew automatically for subsequent successive one-year renewal periods unless Scilex Pharma or the Developers terminate it upon six-months’ written notice.

On February 16, 2017, Scilex Pharma entered into a Commercial Supply Agreement (as amended, the “Supply Agreement”) with the Developers to provide commercial supply of ZTlido and SP-103 to Scilex Pharma. The Supply Agreement contains standard terms regarding term, termination, payment, product quality and supply. In addition, the agreement provides additional terms regarding the calculation and amount of marketing expenses that may be deducted from net sales for purposes of determining the amount of net profit under the Product Development Agreement.

Sales Operations Services

In November 2014, Scilex Pharma entered into a project agreement with a vendor, pursuant to which the vendor has agreed to perform certain services in accordance with written work orders, which was subsequently superseded by a new project agreement entered into in May 2025 (the “Project Agreement”). In connection with the detailing services, the Project Agreement provides that the vendor will provide Scilex Pharma with full-time sales representatives who shall detail the Product by making calls pursuant to a call plan on targets. In connection with the sales operation services, the vendor will provide certain services required for the initial implementation and ongoing operation of the sales force.

In May 2025, Scilex Pharma and the vendor entered into a work order in which the parties agreed to convert substantially all of the sales representatives allocated under the Project Agreement to become employees of the vendor. The work order shall be in effect and remain in effect until the thirty-six months anniversary of the Deployment Date, as set forth in accordance with the terms of the Project Agreement, which is June 3, 2025, or until terminated in accordance with the terms of the Project Agreement or unless extended as provided therein (the “Term”). The Term may be extended for additional periods of one (1) year (each, an “Additional Term”) upon the mutual written agreement of the parties not less than sixty (60) days before the end of the Term or any Additional Term. Scilex Pharma paid a one-time implementation fee of $72 thousands associated with the operational setup and the recruiting of the sales representatives and will pay fixed monthly fee of $1.2 million for year one and $1.3 million for each of year two and year three.

Pursuant to the terms set forth in the Project Agreement, either party may terminate this work order without cause upon ninety (90) days prior written notice to the other party; provided, however, that such termination by Scilex Pharma may not occur prior to the twelve (12) month anniversary of the Deployment Date.

Litigation

From time to time, the Company may be subject to claims and legal proceedings arising in the ordinary course of business. The Company evaluates each matter and assesses its potential financial exposure. If the potential loss from a legal proceeding is considered probable and the amount can be reasonably estimated, the Company records an accrual for the estimated loss. Because the outcome of legal proceedings is inherently uncertain, significant judgment is required in assessing the likelihood of a loss and whether the amount is reasonably estimable. The Company’s assessments and any recorded accruals are based on information available at the time of evaluation. As additional information becomes available, the Company re-evaluates its estimates and may adjust recorded liabilities accordingly.

Former Employee Action

On March 12, 2021, Scilex Pharma and Sorrento (the “Plaintiffs”) filed an action (the “Former Employee Action”) in the Delaware Court of Chancery against the former President of Scilex Pharma, Anthony Mack, and Virpax Pharmaceuticals, Inc. (“Virpax”, and together with Mr. Mack, the “Defendants”), a company founded and then headed by Mr. Mack, alleging, among other things, breach by Mr. Mack of a restrictive covenant agreement with Sorrento related to his sale of his Scilex Pharma stock to Sorrento, tortious interference with that agreement by Virpax, breach of Mr. Mack’s fiduciary duties to Scilex Pharma, aiding and abetting of that breach by Virpax, and misappropriation of Scilex Pharma’s trade secrets by Mr. Mack and Virpax. Such lawsuit sought, among other relief, damages and various forms of injunctive relief. The case was tried from September 12, 2022 to September 14, 2022. On September 1, 2023, the court found in favor of the Plaintiffs on all but three counts deemed to have been waived. In its 95-page opinion, the court instructed the parties to submit supplemental briefing on the appropriate remedy to implement its rulings. On October 18, 2023, the Plaintiffs submitted a supplemental brief on remedies. On November 29, 2023, Defendants submitted a supplemental brief on remedies. On December 21, 2023, the Plaintiffs submitted a supplemental reply brief on remedies. On February 26, 2024, we and Virpax entered into a term sheet regarding a mutual release and settlement agreement, pursuant to which the parties have agreed to resolve the ongoing disputes. On February 29, 2024, we and Virpax entered into a definitive settlement agreement, which provides for, among other things, that Virpax would be obligated to make the following payments to us to settle the Former Employee Action: (i) $3.5 million (the “Initial Payment”) by two business days after the Effective Date (as defined therein), which payment has been made; (ii) $2.5 million by July 1, 2024, which payment has been made on July 8, 2024 and (iii) to the extent any of the following drug candidates are ever sold, royalty payments of (a) 6% of annual Net Sales (as defined therein) of Epoladerm; (b) 6% of annual Net Sales of Probudur and (c) 6% of annual Net Sales of Envelta during the Royalty Term (as defined therein). We and Virpax provided mutual releases of all claims that existed as of the Effective Date, whether known or unknown, arising from any allegations set forth in the Former Employee Action. Plaintiffs’ release relates to claims against Virpax only, which does not affect our claims against Mr. Mack. Plaintiffs have not released Mr. Mack, and litigation against him remains ongoing. The Court requested further briefing on the remedies solely as to the remaining defendant, Mr. Mack. The parties filed further briefing and then presented oral argument on November 15, 2024. The Court’s issued its decision on damages as to Mr. Mack on July 31, 2025, crediting Mr. Mack for settlement amounts previously paid to Plaintiffs by Virpax, on the count for which Mr. Mack was found liable, and assessing costs against Mr. Mack for one-third of Plaintiffs’ attorneys fees. The parties are awaiting the entry of final judgment.

ZTlido Patent Litigation

On June 22, 2022, the Company filed a complaint against Aveva Drug Delivery Systems, Inc. (“Aveva”), Apotex Corp., and Apotex, Inc. (together, “Apotex”) in the U.S. District Court for the Southern District of Florida (the “ZTlido Patent Litigation”) alleging infringement of certain Orange Book listed patents covering ZTlido (the “ZTlido Patents”). The ZTlido Patent Litigation was initiated following the submission by Apotex, in accordance with the procedures set out in the Hatch-Waxman Act, of an abbreviated new drug application (“ANDA”). Apotex’s ANDA seeks approval to market a generic version of ZTlido prior to the expiration of the ZTlido Patents and alleges that the ZTlido Patents are invalid, unenforceable, and/or not infringed. The Company is seeking, among other relief, an order that the effective date of any FDA approval of Apotex’s ANDA be no earlier than the expiration of the asserted patents listed in the Orange Book, the latest of which expires on May 10, 2031, and such further and other relief as the court may deem appropriate. Apotex and Aveva were subject to an automatic 30-month stay preventing them from selling a generic version of ZTlido during that time, which was extinguished by the U.S. District Court decision described below. However, to our knowledge, Aveva has not received FDA approval for any generic version of ZTlido. The two Apotex entities were dismissed from the litigation without prejudice, as they no longer had an interest in the generic product that Aveva seeks to market. Before trial, Aveva dropped its challenge to the validity and enforceability of the Company’s patents. Trial in the ZTlido Patent Litigation was held from July 8, 2024 to July 11, 2024. Final post-trial briefing was submitted by the parties on July 25, 2024, and the case was submitted to the U.S. District Court for the Southern District of Florida. On August 26, 2024, that court issued a decision finding that Aveva’s product does not infringe the Company’s ZTlido Patents. The Company is appealing that decision to the U.S. Court of Appeals for the Federal Circuit, and it filed a Notice of Appeal with the U.S. District Court for the Southern District of Florida on September 25, 2024. Briefing has been completed in that appeal. The parties are awaiting the Federal Circuit’s scheduling of oral argument.

Former Employees Litigation

On November 3, 2023, four former employees of the Company filed a complaint in California Superior Court in San Diego County, consisting of claims for back compensation that they allege were promised but not paid to them. The Company investigated those claims, conducted and responded to discovery, and vigorously contested this lawsuit. The parties concluded a settlement of all claims on June 2, 2025, the terms of which are confidential.

Operating Leases

The Company leases administrative and research and development facilities under various non-cancelable lease agreements. Facility leases generally provide for periodic rent increases and may include options to extend. As of June 30, 2025, the Company’s leases have remaining lease terms of approximately 2.3 years. The terms of the Company’s leases, ranging from 3 to 5 years, include extension options that are not reasonably certain to be exercised. Many of the Company’s leases are subject to variable lease payments. Variable lease payments are recognized in the period in which the obligations for those payments are incurred, are not included in the measurement of the right-of-use (“ROU”) assets or lease liabilities, and are immaterial.

As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company calculates the associated lease liability and corresponding ROU asset upon lease commencement using a discount rate based on a credit-adjusted secured borrowing rate commensurate with the term of the lease. As of June 30, 2025, the Company has no finance leases.

Lease expense was $0.2 million and $0.3 million for the three months ended June 30, 2025 and 2024, and $0.5 million for each of the six months ended June 30, 2025 and 2024 and was primarily comprised of operating lease costs. The lease expense included variable lease costs and sublease income, which were immaterial for the periods presented.
