Full-year 2026 outlook
- Revenuemore than $175 million
- Noteat least a 40% Adjusted EBITDA margin for 2026
- Notefull-year 2026 adjusted gross margin to exceed 70%
What drove it
- Revenue growth was driven by the addition of HEMANGEOL revenue and higher product sales for INCRELEX, ALKINDI SPRINKLE, KHINDIVI, GALZIN, DESMODA and Carglumic Acid.
- Third-quarter revenue included $1.2 million of revenue from INCRELEX and GALZIN sales outside the United States.
- Gross-profit growth reflected increased product sales and a favorable change in product mix.
- The Company recorded all-time high active patient counts for INCRELEX, HEMANGEOL, ALKINDI SPRINKLE, KHINDIVI, DESMODA and GALZIN.
- The third-quarter income tax benefit reflected the release of the valuation allowance associated with federal and a portion of state deferred tax assets.
Concerns
- GAAP net income included an income tax benefit from the release of deferred tax asset valuation allowances; this benefit was removed for purposes of non-GAAP net income.
- General and administrative expense rose 98%, driven by higher stock-based compensation, compensation and benefits, operating costs supporting a larger business and expanded portfolio, and higher FDA fees.
- Research and development expense increased primarily because of the $3 million payment for ASN-001 rights and higher Glyburide Oral Suspension development spending.
- ET-700 hepatic copper uptake decreased 12%, compared with a 46% decrease with GALZIN; the Company plans additional 2027 study arms evaluating faster-release formulations.
What to watch
- KHINDIVI label-expansion PAS review, with a May 28, 2027 PDUFA date.
- LIBERVANT NDA review, with a March 29, 2027 PDUFA date, and the anticipated April 2027 launch if approved.
- ASN-001 bioavailability study progress and the anticipated 2027 NDA submission.
- ET-900 Phase 2 trial enrollment and dosing anticipated in the first quarter of 2027.

Analysis
Eton reported a record third quarter, with total net revenue of $57.9 million versus $22.5 million in the prior-year period, a reported 158% increase. Product sales were the sole source of third-quarter revenue, while the nine-month comparison also reflects the absence of prior-year licensing revenue. Management attributed the quarterly increase to HEMANGEOL and growth across INCRELEX, ALKINDI SPRINKLE, KHINDIVI, GALZIN, DESMODA and Carglumic Acid. The Company also cited all-time high active patient counts across its key promoted products.
Profitability expanded materially. GAAP gross profit was $44.3 million compared with $7.9 million, while adjusted gross margin was 80% compared with 45%. Adjusted EBITDA was $28.5 million, or 49% of revenue, compared with $2.9 million, or 13% of revenue, in the prior-year quarter and 43% in the second quarter of 2026. Management attributed the gross-profit improvement to greater product sales and favorable product mix.
GAAP net income was $35.2 million, or $1.06 per diluted share, compared with a net loss of $1.9 million, or $0.07 per diluted share. The result included a tax benefit from releasing valuation allowances on federal and certain state deferred tax assets. Non-GAAP net income, which excluded that one-time benefit, was $16.5 million, or $0.50 per diluted share, compared with $1.5 million, or $0.04 per diluted share. Higher operating costs accompanied the commercial expansion: R&D reflected the $3 million ASN-001 rights payment and Glyburide spending, while G&A rose 98% amid compensation, headcount, portfolio-support costs and FDA fees.
The balance sheet and cash generation strengthened through the first nine months. Cash and cash equivalents reached $55.6 million at September 30, 2026, and net cash from operating activities was $49.9 million for the nine-month period. Investing cash use included $18.2 million of product license rights purchases, while financing activity included an $8.0 million long-term debt repayment.
Management raised full-year 2026 revenue guidance to more than $175 million from more than $145 million and increased its Adjusted EBITDA margin outlook to at least 40% from at least 35%. The forward commercial and development agenda includes anticipated 2027 milestones for KHINDIVI, LIBERVANT, ASN-001, ET-900 and Glyburide Oral Suspension. The report also identifies product and regulatory execution as central to sustaining the current growth and margin trajectory.
Management, verbatim
Eton delivered another record quarter, with revenue of $57.9 million, up 158% year over year, and surpassed our $200 million annualized revenue run rate goal five quarters ahead of schedule. The team also demonstrated exceptional operational execution, significantly expanding margins, and delivering an adjusted EBITDA margin of 49%. We are raising both our revenue and adjusted EBITDA guidance for 2026, reflecting the strong momentum in our business.
Sean Brynjelsen, CEO of Eton Pharmaceuticals
Growth remained strong across the portfolio, with record levels of active patients for all of our key products, including HEMANGEOL ® , INCRELEX ® , ALKINDI SPRINKLE ® , KHINDIVI ® , GALZIN ® and DESMODA TM . Our recent licensing agreement for LIBERVANT ® adds another potential major 2027 launch and will expand us into neurology, giving us an additional therapeutic platform to build on with future transactions.
