First Quarter 2026 Financial Highlights
The Company delivered strong first quarter 2026 results.

• Total Q1 2026 product revenue, net was $149.3 million, a 5.6% year-over-year increase. Promoted products, FIRDAPSE® & AGAMREE®, totaled $135.6 million, a 28.2% year-over-year increase.

• FIRDAPSE Q1 2026 product revenue, net was $98.9 million, an 18.1% year-over-year increase, primarily driven by increases in sales volumes.

• AGAMREE Q1 2026 product revenue, net was $36.7 million, compared to product revenue, net of $22.0 million in Q1 2025. The results underscore continued sales volume growth and increasing prescriber engagement.

• FYCOMPA® Q1 2026 product revenue, net was $13.8 million, a 61.3% year-over-year decrease following loss of exclusivity in 2025.

First Quarter 2026 Additional Financial Results

Cost of sales: Cost of sales for the first quarter of 2026 was $14.5 million, compared to $17.9 million in the first quarter of 2025. In addition to the reductions to FIRDAPSE royalties that occurred at the end of 2025, in January 2026, the Company completed seven years from the date of first commercial sale of FIRDAPSE in the U.S. On that date, the royalty on net U.S. sales that the Company previously paid to Catalyst’s licensor at a tiered rate of 7% to 10% of net U.S. sales of FIRDAPSE expired. Also, on January 1, 2026, as part of the Company's acquisition and license agreement regarding RUZURGI® (amifampridine) with Jacobus, the royalty rate the Company pays Jacobus on net U.S. sales of any amifampridine product increased from 1.5% to 2.5%. As a result, the overall royalty rate that the Company pays to its upstream licensors for net U.S. sales of FIRDAPSE is 6%, which is down from a previous maximum rate of 18.5%.

Royalties on AGAMREE include a base royalty of 7% of net sales up to $250 million with additional increases as net sales increase. This base royalty is due to the Company’s licensor, which reflects obligations owed by the licensor to its upstream licensors as well as an additional royalty of 7% of net sales in excess of $100 million and up to $200 million with additional increases as net sales increase. This additional royalty is due to the licensor under the Company’s agreement.

Research and development expenses: Research and development expenses for the first quarter of 2026 were $2.7 million, compared to $3.9 million in the first quarter of 2025.

Selling, general, and administrative expenses: Selling, general, and administrative (SG&A) expenses for the first quarter of 2026 were $49.3 million, compared to $46.9 million in the first quarter of 2025.

Amortization of intangible assets: Amortization of intangible assets for the first quarter of 2026 were $9.7 million, compared to $9.3 million in the first quarter of 2025.

Operating income: Operating income for the first quarter of 2026 was $73.2 million, compared to $63.4 million in the first quarter of 2025, representing an increase of approximately 15.6%.

GAAP net income: GAAP net income for the first quarter of 2026 was $63.7 million ($0.52 per basic and $0.50 per diluted share), compared to GAAP net income of $56.7 million ($0.47 per basic and $0.45 per diluted share) in the first quarter of 2025.

Non-GAAP net income: Non-GAAP net income for the first quarter of 2026 was $100.3 million ($0.82 per basic and $0.79 per diluted share), compared to non-GAAP net income of $86.6 million ($0.71 per basic and $0.68 per diluted share) in the first quarter of 2025. Non-GAAP net income for all periods excludes from net income stock-based compensation, depreciation, amortization of intangible assets, and the income tax provision.

Tax rate: The Company’s effective income tax rate was 24.3% and 20.4% for the three months ended March 31, 2026, and 2025, respectively. Differences in the effective tax and the statutory federal income tax rate of 21% are driven by state income taxes and anticipated annual permanent differences offset by equity compensation deductions.

Cash and cash equivalents: Cash and cash equivalents were $755.9 million as of March 31, 2026.

The Company’s Form 10-Q for the first quarter of 2026, filed with the U.S. Securities and Exchange Commission on May 11, 2026, provides more detailed financial information and analysis of our financial condition and results of operations.
