Other Financial Highlights

Operating loss was $58.0 million for the second quarter of 2026, compared to an operating earnings of $12.1 for the same period in 2025. The change was primarily due to a non-cash $54.9 million intangible asset impairment charge related to APOKYN in the second quarter of 2026, an increase in selling, general, and administrative expenses associated with the collaboration agreement with Biogen Inc., partially offset by higher revenues.

Adjusted operating earnings (non-GAAP)⁽¹⁾ were $31.2 million in the second quarter of 2026, compared to $40.9 million for the same period in 2025.

Net loss and diluted loss per share were $58.4 million and $1.01 for the second quarter of 2026, respectively, compared to net earnings and diluted earnings per share of $22.5 million and $0.40 for the same period in 2025.

Cash, cash equivalents, and current marketable securities were approximately $372.1 million as of June 30, 2026, compared to $308.7 million as of December 31, 2025. This increase was primarily due to cash generated from operations.

Non-GAAP Financial Information

This press release contains financial measures that present financial information which do not comply with United States generally accepted accounting principles (GAAP). The non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, or superior to measures prepared in accordance with GAAP. Non-GAAP adjusted operating earnings on a historical and projected basis adjusts for non-cash share-based compensation expense, depreciation and amortization, intangible asset impairment charges and changes to fair value of contingent consideration, and for factors that are unusual, non-recurring or unpredictable, and excludes those costs, expenses, and other specified items presented in the reconciliation tables in this press release. We also present total revenues excluding net sales of Trokendi XR (GAAP) and Oxtellar XR (GAAP), which is a non-GAAP measure and is calculated as total revenues (GAAP) less net product sales of Trokendi XR (GAAP) and Oxtellar XR (GAAP). Beginning in the year a product loses exclusivity due to generic entrants, we generally do not expect net product sales of such products to constitute a significant part of our revenue in the future. We also present total revenues from commercial products, which is also a non-GAAP measure and is calculated as the combined total of total net product sales (GAAP) and collaboration revenues (GAAP). We believe that the use of non-GAAP financial measures provides useful supplemental information to management, investors, analysts and others regarding the Company's revenue and results of operations and assist management, investors, analysts, and others in understanding and evaluating our revenue growth and the performance of the business.

There are limitations associated with the use of non-GAAP financial measures and therefore comparability may be limited. These limitations include: non-GAAP financial measures that may not be entirely comparable to similarly titled measures used by other companies; these may not reflect all items of income and expense, as applicable, that affect our operations; there may be potential differences among calculation methodologies; these may differ from the non-GAAP information used by other companies, including peer companies. We mitigate these limitations by reconciling the non-GAAP financial measure to the most comparable GAAP financial measure. Investors are encouraged to review the reconciliation. The Company's 2026 financial guidance is also being provided on both a GAAP and a non-GAAP basis.
