ROCKVILLE, Md., May 06, 2025 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (NASDAQ:SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced financial results for the first quarter 2025 and associated Company developments.

"Our first quarter results reflect, once again, double-digit revenue growth from our core products, as well as strong growth in adjusted operating earnings," said Jack Khattar, President and CEO of Supernus. "In addition, we are pleased to be bringing ONAPGO to market, another growth driver for our business. ONAPGO represents a novel approach for adults with Parkinson's disease who are experiencing motor fluctuations."

Commercial Highlights

Total IQVIA prescriptions⁽²⁾ for Qelbree were 214,908 for the first quarter 2025, an increase of 22% compared to the same period in the prior year. For March 2025, total monthly prescriptions reached an all-time high of 75,277. Qelbree continues to expand its base of prescribers, with approximately 34,416 prescribers in the first quarter of 2025, up from 27,902 prescribers in the same period last year.
In April 2025, the Company launched ONAPGO, the first and only subcutaneous apomorphine infusion device for the treatment of motor fluctuations in adults with advanced Parkinson's disease. Initial physician response is encouraging based on very early activity in the launch.

Total revenues excluding Trokendi XR and Oxtellar XR net sales (non-GAAP)⁽¹⁾	$	126.8	$	100.7	26	%

Other Financial Highlights

Operating loss was $(10.3) million for the three months ended March 31, 2025, compared to operating loss of $(3.2) million for the same period in 2024. The change was primarily due to higher contingent consideration loss, mainly related to the achievement of ONAPGO-related milestones, and higher selling and marketing expenses.
Adjusted operating earnings (non-GAAP) were $25.9 million for the three months ended March 31, 2025, compared to $22.3 million for the same period in 2024.
Net loss and diluted loss per share were $(11.8) million and $(0.21) for the three months ended March 31, 2025, compared to net earnings and diluted earnings per share of $0.1 million and $0.00 for the three months ended March 31, 2024.
At March 31, 2025, cash, cash equivalents, and current and long-term marketable securities were approximately $463.6 million compared to $453.6 million as of December 31, 2024. This increase was primarily due to cash generated from operations partially offset by the $25.0 million payment of ONAPGO-related milestone in the first quarter of 2025.

Full Year 2025 Financial Guidance

For the full year 2025, the Company reiterates its full year financial guidance as set forth below (dollars in millions):

	Current Guidance (as of February 25, 2025)
Total revenues (includes approximately $65 million - $75 million of Trokendi XR and Oxtellar XR)⁽⁵⁾⁽⁶⁾	$600 - $630
Combined R&D and SG&A expenses	$435 - $460
Operating earnings (loss)	$(15) - $10
Adjusted operating earnings (non-GAAP)⁽¹⁾	$105 - $130

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. In addition to non-GAAP adjusted operating earnings, 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 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 2025 financial guidance is also being provided on both a GAAP and a non-GAAP basis.
