Patient enrollment is ongoing in the Phase IV open-label study to assess the efficacy of Qelbree over the course of 14 weeks of treatment in approximately 500 adults with attention deficit hyperactivity disorder (ADHD) and mood symptoms. The primary outcome measure is change from baseline in the Adult ADHD Investigator Symptom Rating Scale (AISRS). Product Pipeline Update SPN-830 (apomorphine infusion device) for treatment of Parkinson's disease (PD) In April 2024, the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) in response to the Company's New Drug Application (NDA) for SPN-830. The CRL indicates that the review cycle for the application is complete, but that the application is not ready for approval in its present form. The Company will announce the timing for its resubmission after further discussion with the FDA, which is expected to take place in May 2024. SPN-820 – Novel first-in-class molecule that increases mTORC1 mediated synaptic function for depression More than half the number of planned patients have been enrolled in the ongoing Phase IIb multi-center randomized double-blind placebo-controlled parallel design study of SPN-820 in adults with treatment-resistant depression. The study is examining efficacy and safety of SPN-820 over a course of five weeks of treatment in approximately 268 patients in up to 50 clinical sites. The primary outcome measure is the change from baseline to end of treatment period on the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score. Topline data from the Phase IIb trial is expected in the first half of 2025. The Company has initiated a Phase II open-label study in approximately 40 subjects with major depressive disorder (MDD).

Total net product sales were $138.4 million, compared to $140.6 million in the same period in 2023. The decrease was primarily due to the decline in net sales of Trokendi XR offset by an increase in net sales of Qelbree. Total revenues excluding Trokendi XR and Oxtellar XR net product sales (non-GAAP) increased 12% compared to the same period in 2023. Other Financial Highlights Operating loss was $(3.2) million compared to operating earnings of $5.2 million in the same period in 2023. The decrease was primarily due to lower royalty revenue. Adjusted operating earnings (non-GAAP) were $22.3 million compared to $30.5 million in the same period in 2023. Net earnings and diluted earnings per share were $0.1 million and $0.00, respectively, compared to $16.9 million and $0.29, respectively, in the same period in 2023. At March 31, 2024, cash, cash equivalents, and current and long-term marketable securities were approximately $309.4 million compared to $271.5 million as of December 31, 2023. This increase was primarily due to cash generated from operations. Full Year 2024 Financial Guidance For the full year 2024, the Company reiterates its full year 2024 financial guidance as set forth below (dollars in millions).   Amount(as of February 27, 2024) Total revenues (includes approximately $125 - $135 million of Trokendi XR and Oxtellar XR)(4)(5) $580 - $620 Combined R&D and SG&A expenses $430 - $460 Operating loss(6) $(30) - $(0) Adjusted operating earnings (non-GAAP)(1) $80 - $110 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 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. In addition to non-GAAP adjusted operating earnings, we also present total revenues excluding net product 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 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 2024 financial guidance is also being provided on both a GAAP and a non-GAAP basis.
