We need to look past the headline growth, though, to see how their high-touch specialty pharmacy 'Place' and patient support 'Promotion' underpin the premium 'Price' they are achieving. Dive in below to see the precise levers driving this rare disease success story.

Eton Pharmaceuticals, Inc. (ETON) - Marketing Mix: Product

You're looking at the core offerings of Eton Pharmaceuticals, Inc. as of late 2025. The company's product strategy centers entirely on developing, acquiring, and commercializing treatments for rare diseases, often targeting the pediatric endocrinology or metabolic endocrinology space.

Eton Pharmaceuticals, Inc. maintains a commercial portfolio of eight established rare disease products. This portfolio is the engine driving current revenue, which reached $22.5 million in product sales for the third quarter of 2025. The company reported that its Q2 2025 product sales were $18.9 million, marking a 108% year-over-year increase. Management projected an annual revenue run-rate of $80 million by the third quarter of 2025.

The current commercial offerings include:

ALKINDI SPRINKLE® is considered the flagship product, and 2025, its fifth calendar year on the market, is on pace to be its strongest year by number of patients on therapy and new patient referrals. Eton Pharmaceuticals, Inc. expects peak sales for KHINDIVI™ combined with ALKINDI SPRINKLE® to exceed $50 million annually.

The year 2025 saw strategic relaunches to enhance patient access and revenue contribution from key assets. INCRELEX® was relaunched in the U.S. following its acquisition in late 2024, reaching 100 active patients by July 2025, six months ahead of projections. GALZIN® was relaunched in March 2025, and by the end of 2025, it achieved its target of over 200 active patients.

The core U.S. business gross margin was estimated to be 'just over 70% for the quarter' when excluding transition costs impacting the reported Q3 2025 adjusted gross margin of 45%.

The late-stage pipeline is focused on advancing near-term value catalysts:

• ET-600 (desmopressin oral solution): New Drug Application (NDA) accepted for review on July 8, 2025, with a Prescription Drug User Fee Act (PDUFA) target action date set for February 25, 2026. This product has patent protection extending through 2044. The indication, arginine vasopressin deficiency (AVP-D), impacts an estimated 3,000 pediatric patients in the United States.
• ET-700: An internal development candidate representing an extended-release zinc formulation, a follow-on to GALZIN for Wilson disease. A proof-of-concept study is planned for the end of 2025.
• Other late-stage candidates include Amglidia®, ET-800, and ZENEO® hydrocortisone autoinjector.

The company is preparing for a potential launch of ET-600 in the first quarter of 2026 if approved.

Eton Pharmaceuticals, Inc. (ETON) - Marketing Mix: Place

Eton Pharmaceuticals, Inc. structures its distribution to support its focus on rare disease treatments, which inherently requires specialized access points rather than broad retail coverage.

Distribution relies on a high-touch specialty pharmacy network. For the acquired product INCRELEX®, availability in the United States is exclusively through AnovoRx, a specialty pharmacy focused on rare and chronic conditions. This arrangement is critical for a biologic product requiring specialized handling and patient support services.

Primary market focus is the United States for commercial products. The strategic out-licensing of international rights allows Eton Pharmaceuticals, Inc. to concentrate its commercial efforts on the U.S. market. This focus supports the company's growth opportunities, including three rare disease product launches planned for 2025. By the end of 2025, Eton Pharmaceuticals, Inc. expects to exit the year at an approximately $80 million annual revenue run rate.

Out-licensed international rights for INCRELEX® to partners like Esteve and Ipsen. Commercial rights for INCRELEX® in territories outside the U.S. were out-licensed to Esteve Pharmaceuticals, S.A.. Esteve will hold these rights for up to ten years and has an option to acquire them later. Eton supplies the product to Esteve at a fixed transfer price. The initial cash payment received for this ex-U.S. licensing agreement subsequent to the second quarter of 2025 was $4.6 million.

The distribution model for specific products can be summarized as follows:

Utilizes the Eton Cares patient support program for direct patient access and adherence. This program is integral to the distribution process, especially for specialty pharmaceuticals. For INCRELEX®, AnovoRx administers the Eton Cares Program. For ALKINDI SPRINKLE®, patients are automatically enrolled to receive support services. The program offers financial assistance, including $0 co-pays for commercially eligible patients. The success of this high-touch support is evident in the INCRELEX® patient base, which grew from 67 active patients in December 2024 to 100 active patients by the end of July 2025, reaching a target initially set for the end of 2025.

Products are distributed to specialized clinics, like pediatric endocrinology centers. Eton Pharmaceuticals, Inc. leverages its existing sales team and relationships within the pediatric endocrinology community to drive awareness and adoption of its products. As of August 2025, Eton Pharmaceuticals, Inc. has eight commercial rare disease products available.

The distribution support structure involves several key functions:

• Insurance verification and benefits investigation
• Pharmacist follow-up and scheduling delivery
• Registered nurse check-ins for treatment adherence
• Delivery of treatment in as soon as 24 hours for newborns awaiting discharge

The Q3 2025 product sales reached $22.5 million, reflecting 129% year-over-year growth.

Eton Pharmaceuticals, Inc. (ETON) - Marketing Mix: Promotion

Promotion activities for Eton Pharmaceuticals, Inc. focus heavily on patient access, community education, and transparent communication with the financial community regarding its rare disease portfolio.

Patient-Centric Support for GALZIN®

Eton Pharmaceuticals launched GALZIN® (zinc acetate) capsules in March 2025, which is the only FDA-approved zinc therapy for the maintenance treatment of Wilson disease in patients previously treated with a chelating agent. To ensure access for this ultra-rare patient population, which is estimated at fewer than 5,000 patients in the U.S., the Company deployed the Eton Cares patient support program. This program, administered in partnership with Optime Care, offers a $0 co-pay for all eligible commercial patients, alongside prescription fulfillment and insurance benefits investigation services. As of the Q3 2025 report, GALZIN® has achieved over 200 active patients, meeting the year-end 2025 target ahead of schedule.

Targeted Engagement for INCRELEX®

For INCRELEX® (mecasermin injection), Eton leverages its dedicated pediatric endocrinology sales force following its January 2025 U.S. relaunch. This targeted engagement is crucial as Severe Primary IGF-1 Deficiency (SPIGFD), the indication for INCRELEX®, is estimated to affect approximately 200 patients in the U.S. and is considered an underdiagnosed and undertreated condition. The promotional focus is on building awareness within this specialized community. The revenue and patient count for INCRELEX® are tracking well ahead of original projections for the product.

Educational Campaigns and Label Expansion Strategy

The launch of GALZIN® included an implied educational campaign to target patients historically using non-FDA-approved alternatives, such as unapproved compounded products or over-the-counter supplements, due to past availability and affordability issues. Concurrently, Eton is advancing its pipeline promotion strategy through clinical development milestones. The Company detailed plans for a supplemental FDA filing in the second half of 2025 to harmonize the U.S. and EU labels for INCRELEX®. If successful, this harmonization could potentially increase the U.S. eligible patient pool for INCRELEX® fivefold, from approximately 200 to up to 1,000 patients. The initiation of the INCRELEX label harmonization clinical study is planned for 2026.

Proactive Investor Engagement

Eton Pharmaceuticals maintains proactive communication with the investment community to convey operational performance and strategic direction. The Q3 2025 financial results were reported on November 6, 2025, with management hosting a conference call at 4:30 p.m. ET. The financial results highlighted product sales of $22.5 million, representing a 129% year-over-year growth, and an Adjusted EBITDA of $2.9 million. Further engagement is scheduled for early December 2025.

The promotional structure utilizes specific financial incentives and community outreach to drive adoption and awareness across its specialized portfolio.

• Eton Cares offers $0 co-pay for eligible GALZIN® patients.
• GALZIN® commercialization began in Q1 2025, supported by the metabolic sales force.
• INCRELEX® patient count is tracking well ahead of projections.
• The Q3 2025 product sales reached $22.5 million.
• Management presented at the Piper Sandler Conference on December 4, 2025.
• Proposed INCRELEX® label harmonization study initiation is set for 2026.

The company is using its sales infrastructure, which includes a specialized metabolic sales force for GALZIN® and a dedicated pediatric endocrinology sales force for INCRELEX®, to directly engage healthcare professionals treating the specific rare conditions.

You're looking at the financial mechanics behind how Eton Pharmaceuticals, Inc. (ETON) prices its rare disease portfolio as of late 2025.

The top-line performance shows significant pricing power and commercial execution. Eton Pharmaceuticals, Inc. (ETON) achieved Q3 2025 product sales of $22.5 million, which represents a 129% increase year-over-year.

For the full-year 2025, the adjusted gross margin is projected to be approximately 70%.
