CLEVELAND, August 13, 2026 – Abeona Therapeutics Inc. (Nasdaq: ABEO) today reported financial results for the second quarter of 2026 and provided an update on commercial execution for ZEVASKYN (prademagene zamikeracel).

Commercial Update

Steady launch-year growth for ZEVASKYN. Commercial execution continued to strengthen during the second quarter of 2026 with five patients treated with ZEVASKYN. In the third quarter of 2026 to-date, three patients have completed treatments. Since launch, 12 patient treatments have been completed. Revenue was not recognized for two patients due to low manufacturing yield or not meeting lot release specifications.

Expanded qualified treatment center (QTC) network and increased patient onboarding. Abeona continues to expand the ZEVASKYN QTC network, and the number of QTCs that have treated patients with ZEVASKYN has increased. Key recent milestones include:

Secured CMS New Technology Add-On Payment (NTAP) status for ZEVASKYN. Effective October 1, 2026, ZEVASKYN will have NTAP status under the fiscal year 2027 Hospital Inpatient Prospective Payment System Final Rule from the Centers for Medicare & Medicaid Services (CMS). NTAP provides a pathway for eligible hospitals to receive a supplemental payment from CMS, in addition to the base diagnosis-related group (DRG) payment, when treating Medicare beneficiaries with ZEVASKYN. This designation is expected to support hospital adoption and help facilitate access for Medicare patients, who represent approximately 10 percent of RDEB patients.

Continued engagement raising RDEB community awareness. The Company presented 5-year long-term follow-up data after ZEVASKYN application from the VIITAL Phase 3 clinical study and a case report from the longest follow-up of 12 years from the Phase 1/2a study. Presentations were made at key medical congresses, including the Society for Investigative Dermatology (SID) and Society for Pediatric Dermatology (SPD) annual meetings, as well as the debra Care Conference, to drive physician awareness, patient identification, and enable patient referral to the expanding QTC network.

“Our confidence in ZEVASKYN’s substantial opportunity is reinforced by our launch progress and experience to date as we engage with a growing number of patients and expand our QTC network,” said Vish Seshadri, Ph.D., Chief Executive Officer of Abeona Therapeutics. “As early real-world experience with ZEVASKYN matures across activated sites, we expect to drive broader adoption and long-term growth.”

Second Quarter 2026 Financial Results

Net ZEVASKYN revenue for the quarter ended June 30, 2026 increased 31% quarter-over-quarter to $11.4 million, compared to $8.7 million in the first quarter of 2026. While five patients were treated with ZEVASKYN during the second quarter of 2026, revenue was recognized for four treatments as one batch yielded fewer than the threshold number of sheets for revenue recognition.

Research and development (R&D) expenses were $5.0 million for the second quarter of 2026 compared to $9.6 million in the first quarter of 2026, which included the one-time, up-front cost of $7.0 million for in-licensing ABO-701.

Selling, general and administrative expenses were $15.8 million for the second quarter of 2026, compared to $19.5 million for the first quarter of 2026. The decrease primarily reflects fewer engineering runs and less manufacturing training costs in the second quarter of 2026.

Net loss was $(20.2) million, or $(0.35) per basic and diluted common share, for the quarter ended June 30, 2026. Net loss for the first quarter of 2026 was $(17.1) million, or $(0.30) per basic and diluted common share.

Cash, cash equivalents and short-term investments totaled $146.8 million as of June 30, 2026, compared to $191.4 million as of December 31, 2025.

Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, numerous risks and uncertainties, including but not limited to our ability to maintain existing and obtain additional regulatory approvals of ZEVASKYN® and any future product candidates; our ability to successfully commercialize and market ZEVASKYN® and any future product candidates, if approved, and the timing of any commercialization and marketing efforts; our ability to manufacture sufficient batches of ZEVASKYN® to meet demand; our ability to manufacture ZEVASKYN® batches that meet certain product release specifications that were required by FDA at the time of BLA approval and implemented based on a limited clinical dataset; the FDA’s willingness to revise such release specifications to reflect real-world manufacturing experience; our ability to manufacture from provided biopsy material a ZEVASKYN® batch for which revenue may ultimately be recognized, which depends on such factors as qualified treatment centers obtaining biopsy samples from ZEVASKYN® patients of sufficient quality to act as starting material for manufacturing ZEVASKYN®, patient-to-patient variability in cell growth during the ZEVASKYN® manufacturing process, patient health deterioration in close proximity to ZEVASKYN® treatment such that treatment is no longer possible, and expiration of ZEVASKYN®’s 84-hour shelf-life before surgical application of ZEVASKYN® can be performed; our ability to activate additional qualified treatment centers to administer ZEVASKYN® on patients; the ability of qualified treatment centers to enroll patients for treatment or administer ZEVASKYN® on patients; our ability submit an investigational new drug application for ABO-701 and enroll patients in new clinical trials; our ability to access additional financial resources and/or our financial flexibility to reduce operating expenses if required; our ability to obtain additional equity funding from current or new stockholders; the potential impact of unpredicted changes in the structure and/or administration of the United States government or its agencies; our ability to out-license technology and/or other assets, deferring and/or eliminating planned expenditures, restructuring operations and/or reducing headcount, and sales of assets; the dilutive effect that raising additional funds by selling additional equity securities would have on the relative equity ownership of our existing investors, including under our existing at-the-market sale agreement; the outcome of any interactions with the FDA or other regulatory agencies relating to any of our products or product candidates; our ability to continue to secure and maintain regulatory designations for our product candidates; our ability to develop manufacturing capabilities compliant with current good manufacturing practices for our product candidates; our ability to manufacture cell and gene therapy products and produce an adequate product supply to support clinical trials and potentially future commercialization; the rate and degree of market acceptance of our product candidates for any indication once approved; our ability to meet our obligations contained in license agreements to which we are party; and macroeconomic uncertainty resulting from changes to U.S. trade policy, including current or future tariffs or other trade restrictions.
