The Company recognized $20.0 million of licensing revenue as of March 31, 2026 related to the achievement of a commercial milestone under our collaboration agreement with Shionogi.
Adjustments related to prior year sales for the three months ended March 31, 2026 were approximately 1% of net product sales. Adjustments related to prior year sales for the three months ended March 31, 2025 were approximately 5% of net product sales. In 2025, the Company had favorable actual returns experience and as a result, the Company changed its estimated provision for product returns based on the most recent experience. Adjustments related to prior year sales for the three months ended March 31, 2025 were primarily attributable to Qelbree.
We do not currently own or operate manufacturing facilities for the commercial production of any of our commercial products. We currently depend on third-party clinical manufacturing organizations (CMOs), who offer a comprehensive range of contract manufacturing and packaging services, in various countries for the supply of active product ingredients (API), and finished goods for our commercial products. For most of our commercial products, we rely on single source suppliers to produce and package final dosage forms for our products and raw materials, including API.

On November 4, 2025, the Company announced that due to stronger than expected demand for ONAPGO, supplier constraints were impacting the Company's ability to fully meet this demand. ONAPGO is manufactured in Europe, supplied to us by our ONAPGO licensing partner, and packaged in the U.S. by a third-party CMO. The Company relies on single source suppliers to produce and package final dosage forms for ONAPGO. In February 2026, the Company announced that it has made progress in securing additional product supply of ONAPGO from the current supplier and, as a result, has resumed new patient initiation. In addition, the Company is working with a second supplier that is expected to begin supplying ONAPGO in 2027, provided regulatory approval is obtained. Any changes in any of the suppliers would require regulatory approval which could cause a further delay in manufacturing and a possible loss of sales, which could affect future operating results adversely.
