Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total net revenues increased 109% year-over-year for the six months ended June 30, 2025. This was driven by increased sales of ALKINDI SPRINKLE and the addition of revenues from INCRELEX and GALZIN.
• Licensing Revenue: The company recognized $3.3M in licensing revenue for the six months ended June 30, 2025, compared to $0 in the prior year. This includes $1.8M from out-licensing INCRELEX rights outside the U.S. and $1.5M from a development milestone for the divestiture of DS-200.
• Expense Increases:
  • R&D Expenses: Increased to $4.9M (YTD 2025) from $3.6M (YTD 2024), primarily due to a $2.2M NDA filing fee for ET-600 and increased development activities for ET-700 and ET-800.
  • G&A Expenses: Increased to $18.9M (YTD 2025) from $10.7M (YTD 2024), driven by higher product advertising, stock-based compensation, and increased headcount.
• Cash Flow: Net cash provided by operating activities turned positive at $10.0M for the six months ended June 30, 2025, compared to a use of $1.2M in the prior year period. This improvement was due to higher cash collections, an FDA filing fee refund, and licensing milestone collections.

Guidance, Outlook, and Risks

• Liquidity: Management believes existing cash ($25.4M) and product revenues will fund operations for at least the next 12 months. However, the company may need to seek additional capital if growth accelerates or spending exceeds estimates.
• Debt Obligations: The company has a credit facility with SWK totaling $30.0M, maturing in December 2027. Quarterly principal payments of $3.0M begin in May 2026. The agreement includes covenants limiting dividends and additional indebtedness.
• Regulatory and Tax Risks:
  • The "One Big Beautiful Bill Act" (OBBBA) enacted in July 2025 includes changes to Medicaid programs (work requirements, cost sharing) and provider tax limits. While the company does not anticipate a material impact in 2025, long-term effects on Medicaid enrollment and reimbursement are uncertain.
  • The company maintains a 100% valuation allowance on deferred tax assets.
• Customer Concentration: Revenue and accounts receivable are highly concentrated. AnovoRx represented 92.0% of net product revenues for the six months ended June 30, 2025.

Key Facts for Investor Verification

• Revenue Concentration: Verify the stability of the relationship with AnovoRx, which accounts for the vast majority of product sales and receivables.
• Debt Service: Confirm the company's ability to meet the $3.0M quarterly principal payments on the SWK loan starting in May 2026.
• Inventory Step-Up: Review the $2.3M inventory step-up expense recognized in cost of sales related to the INCRELEX acquisition and its impact on gross margins.
• Non-GAAP Adjustments: Note that Adjusted EBITDA for the six months ended June 30, 2025, was $6.7M, significantly higher than GAAP Net Loss of $(4.2M), largely due to non-cash stock-based compensation ($3.3M) and inventory step-up ($2.3M).
• Deferred Consideration: Monitor the $4.5M present value of deferred consideration payable to Ipsen S.A. for the INCRELEX acquisition, with payments due over the next two years.
