Changes in net revenues as compared to the third quarter of the prior year were primarily driven by:

​

●BAQSIMI® sales increased primarily due to an increase in unit volumes, contributing $7.4 million in sales driven by our continued marketing efforts. This increase was partially offset by a lower average selling price, as a result of a change in gross-to-net discounts due to changes in chargebacks and rebates and changes to the customer mix, impacting sales of approximately $2.2 million.

●Primatene MIST® sales increased due to a higher average selling price, contributing $1.6 million in sales, as a result of a price increase that went into effect in the second quarter of 2026, and an increase in unit volumes, contributing $1.0 million in sales, as in-store demand for Primatene MIST® continues to grow.

●Lidocaine sales increased primarily due to an increase in unit volumes as a result of an increase in demand caused by other supplier shortages.

●Ipratropium bromide continued to have strong sales during the quarter, following our launch in the second quarter of 2026.

●Epinephrine sales decreased primarily due to lower unit volumes of our pre-filled syringe product, resulting from slower product releases associated with ongoing remediation efforts at our subsidiary, International Medication Systems, Limited (“IMS”).

●Glucagon sales decreased primarily due to a lower average selling price, as a result of increased competition.

●Other pharmaceutical product sales increased primarily due to sales of teriparatide of $6.4 million, which we launched in December 2025. Additionally, API sal
