Aytu BioPharma's Q4 2025 Outlook: Navigating Revenue Challenges and the Exua Launch

Aytu BioPharma's Q4 2025 results reflect a mixed bag of progress and challenges. The company reported full-year net revenue of $66.4 million, driven by its ADHD portfolio, which accounted for $57.6 million, and a growing Pediatric Portfolio contributing $8.8 millionEarnings call transcript: Aytu BioPharma’s Q4 2025 shows growth …^[1]. However, a net loss of $13.6 million for the year—narrowing from $15.8 million in FY24—highlights the fragility of its business modelAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[2]. With generic competition looming for its core ADHD products and a critical product launch on the horizon, Aytu's near-term trajectory hinges on balancing risk and reward.

Near-Term Catalysts: Exua and Strategic Efficiency

The most significant catalyst for Aytu is the impending launch of Exua (gepirone), a first-in-class selective serotonin 5-HT1A receptor agonist for major depressive disorder (MDD). The FDA-approved drug targets a $22 billion U.S. marketAytu BioPharma, Inc.

Strategic cost-cutting measures further bolster Aytu's near-term outlook.

Risks: Revenue Cliff and Market Uncertainty

Aytu faces an existential threat from generic competition. Adzenys, its ADHD drug, faces generic entry by September 1, 2025, while Cotempla will lose exclusivity by July 1, 2026Aytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[9]. These products accounted for 87% of FY25 revenueAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[10], and their erosion could precipitate a sharp decline in top-line growth. Management acknowledges this risk but remains optimistic that Exua's launch will offset these lossesAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[11].

Market acceptance of Exua, however, is far from guaranteed. While first-in-class therapies often command premium pricing, they also face skepticism from prescribers and payers. Aytu's reliance on outsourcing and supply chain partners adds operational complexity, with potential delays or quality issues threatening the product's commercial successAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[12].

Risk/Reward Dynamics: A High-Stakes Transition

Aytu's risk/reward profile is stark. On one hand, Exua's entry into the MDD market offers a transformative opportunity. If it captures even 1% of the $22 billion market, the drug could generate $220 million in annual revenue—a 330% increase over FY25's total revenue. The company's cash reserves and positive EBITDA also provide a runway to navigate the transitionAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[13].

On the other hand, the ADHD revenue cliff is imminent. With Adzenys and Cotempla losing exclusivity within 12 months, Aytu must execute flawlessly on Exua's launch. Failure to secure market share or delays in manufacturing could exacerbate losses. Additionally, the company's reduced R&D spending limits its ability to pivot if Exua underperformsAytu BioPharma Reports Fiscal 2025 Full Year and Fourth Quarter ...^[14].

Conclusion: A Bet on Execution

Aytu BioPharma's Q4 2025 results underscore a company in transition. While its ADHD portfolio remains a cash cow, the clock is ticking. The Exua launch represents a high-stakes gamble: if successful, it could redefine Aytu as a CNS-focused leader; if not, the company risks becoming a cautionary tale in the biopharma sector. Investors must weigh the potential of a novel antidepressant against the certainty of generic erosion and operational uncertainties. For those with a high-risk tolerance, Aytu offers a compelling case of innovation amid adversity.
