Operating Leases

The Company has entered into non-cancellable operating leases with remaining lease terms expiring between 2026 and 2034.

The Company had no finance leases as of December 31, 2025 and 2024.

Legal Proceedings

A liability for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources is recorded in the consolidated financial statements if it is determined that it is probable that a loss has been incurred, and that the amount (or range) of the loss can be reasonably estimated.

On March 4, 2024, a complaint was filed against the Company in the Superior Court of the State of Delaware by ANI Pharmaceuticals, Inc. seeking a declaratory judgement that a provision in an assignment and technology transfer agreement between the Company and ANI, dated November 15, 2010 (the ANI Agreement), obligates the Company to pay ANI a royalty on certain “net sales” of cretostimogene, and (ii) compensatory damages alleging the Company was unjustly enriched by obtaining the benefit of certain non-patent assets under the ANI Agreement without paying adequate consideration to ANI. On July 16, 2025, the Superior Court granted the Company’s motion for summary judgment with respect to ANI’s request for a declaratory judgment to receive royalty payments from the potential sale of cretostimogene but denied the Company’s motion for summary judgment with respect to ANI’s unjust enrichment claim. On July 29, 2025, a jury entered a verdict in favor of the Company, unanimously rejecting all of ANI's claims for unjust enrichment damages. As a result, the Company will not owe ANI a future royalty of 5% on commercial sales of cretostimogene, no damages have been awarded to ANI, and there are no further payments due to ANI under the ANI Agreement. The Company will continue to vigorously defend any post-trial motions and appeals brought by ANI.

Indemnification

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners, and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with officers and members of the Board that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. As of December 31, 2025 and 2024, the Company had not experienced any losses related to these indemnification obligations, and no claims with respect thereto were outstanding.
