Gross margin remained high at 91% on cost of goods sold of $54 thousand.
Operating expenses rose significantly as the company invested in its pipeline and commercialization.

Each one-third payment is scheduled for July 1, 2026, November 1, 2026, and March 1, 2027, subject to continued employment on each vesting date.
