On June 10, 2026, Rocket Pharmaceuticals, Inc. (the “Company”) completed the previously disclosed sale (the “Asset Sale”) of its Rare Pediatric Disease Priority Review Voucher (“PRV”) to a large pharmaceutical company. The PRV was originally issued in connection with the FDA’s approval of the Company’s biologics license application for KRESLADI™ (marnetegragene autotemcel), an autologous hematopoietic stem cell-based gene therapy indicated for the treatment of pediatric patients with severe leukocyte adhesion deficiency-I (LAD-I) due to biallelic variants in ITGB2 without an available human leukocyte antigen-matched sibling donor for allogeneic hematopoietic stem cell transplant.

The Asset Sale was completed pursuant to the terms of an asset purchase agreement, dated April 26, 2026 (the “PRV APA”). Pursuant to the PRV APA, the Company received gross proceeds of $180.0 million from the buyer upon the closing of the Asset Sale.

The foregoing description of the PRV APA does not purport to be complete and is subject to, and qualified in its entirety, by the full text of the PRV APA, a copy of which will be filed with Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026. The representations, warranties, covenants and agreements contained in the PRV APA were made only for the purposes of the PRV APA and as of specific dates, are solely for the benefit of the parties to the PRV APA, and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures. The representations and warranties in the PRV APA were made for the purpose of allocating contractual risk between the parties to the PRV APA instead of establishing these matters as facts. Accordingly, the representations and warranties in the PRV APA are not intended to, and do not, constitute representations and warranties to any person other than the parties to the PRV APA, including investors and security holders, and should not be relied upon as statements of factual information.

On June 12, 2026, the Company issued a press release announcing the closing of the Asset Sale, a copy of the which is furnished as Exhibit 99.1 hereto.

The information under this Item 7.01, including Exhibit 99.1, 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, and shall not be deemed to be incorporated by reference into the filings of the Company under the Securities Act or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
