Positives

• Significant revenue growth: Q2 2025 net sales increased by 4,829% to $39.7 million, and year-to-date net sales increased by 9,678% to $78.8 million, driven by DefenCath commercialization.
• Return to profitability: Achieved net income of $19.8 million in Q2 2025 and $40.5 million for the first six months of 2025, a substantial improvement from prior year losses.
• Strong cash position: Cash and cash equivalents increased to $159.3 million at June 30, 2025, from $40.7 million at December 31, 2024.
• Positive operating cash flow: Generated $49.7 million in net cash from operating activities for the six months ended June 30, 2025, compared to a net cash outflow of $31.4 million in the prior year.
• Strategic acquisition of Melinta Therapeutics: Expected to expand the product portfolio with REZZAYOTM and MINOCIN, offering potential for milestone and royalty payments.
• DefenCath market penetration: The contracted customer base represents approximately 60% of outpatient dialysis centers in the U.S., with a large dialysis organization commencing orders in Q2 2025.
• Favorable tax law changes: The 'One Big Beautiful Bill Act' (OBBBA) is anticipated to positively impact the effective tax rate and future cash tax payments.
• DefenCath reimbursement mechanisms: Secured New Technology Add-On Payment (NTAP), Transitional Drug Add-on Payment Adjustment (TDAPA), and Out-Patient Prospective Payment System (OPPS) pass-through status, providing favorable reimbursement for the product.

Negatives

• Negative impact from accounting estimate change: A change in estimate for Medicaid and commercial rebates negatively impacted Q2 2025 net income by $2.029 million (EPS -$0.03 basic, -$0.02 diluted) and year-to-date net income by $1.695 million (EPS -$0.02 basic/diluted).
• Increased operating expenses: General and administrative expenses increased by 25% in Q2 2025 and 18% year-to-date, primarily due to non-cash stock-based compensation and business development costs.
• Increased research and development expense: R&D expense increased by 275% in Q2 2025 and 279% year-to-date, due to increases in personnel and clinical trial services for ongoing studies.
• Legal proceedings: Ongoing securities and derivative litigation against the company and its officers, with a motion to dismiss recently denied (though later withdrawn for re-evaluation).

Risks

• Melinta acquisition uncertainties: The merger may not be completed on contemplated terms or timeline, or at all, which could adversely affect stock price, future business, and financial results.
• Integration challenges: Significant management attention and resources will be required to integrate Melinta's business, with no assurance of realizing planned synergies or benefits within expected timeframes.
• Loss of key personnel: The acquisition could disrupt businesses and lead to the unanticipated departure of key management and employees from both CorMedix and Melinta.
• Underperformance of Melinta's business: Melinta's business may underperform expectations, and the combined entity may not maintain historical revenue, earnings, or operating efficiency levels.
• Limited recourse for breaches of representations and warranties: Recourse for breaches of representations and warranties under the Merger Agreement is limited and may not cover all losses.
• Tariffs and trade sanctions: Potential for increased costs and reduced profitability due to tariffs on pharmaceutical imports, such as the recently announced 15% EU tariff, which could be difficult to pass on to customers.
• Supply chain reliance: Heavy reliance on third-party manufacturers in Europe for DefenCath, making the company vulnerable to trade policy changes and supply disruptions.
• Uncertainty of future profitability: Despite current profitability, a full valuation allowance is maintained against deferred tax assets due to historical losses and uncertainty regarding sustained full-year profitability.
• Need for additional capital: Future funding requirements may necessitate additional capital raises, which could be dilutive to existing stockholders or involve restrictive debt covenants.

Future Outlook

The company expects to continue funding operations for at least twelve months from existing cash, cash equivalents, short-term investments, and commercial operations. The acquisition of Melinta Therapeutics is anticipated to close in September 2025, expanding the product portfolio and offering potential for future milestone and royalty payments from REZZAYOTM and MINOCIN. The recently enacted 'One Big Beautiful Bill Act' is expected to favorably impact the effective tax rate and future cash tax payments.

Management Comments

• Our primary focus is commercializing our lead product, DefenCath (taurolidine and heparin), in the U.S.
• We believe DefenCath can address a significant unmet medical need.
• We believe the currently contracted customer base represents roughly 60% of the outpatient dialysis centers in the U.S., in terms of the total addressable patient market.
• We expect to continue to fund operations from cash collections of accounts receivable, our cash on hand, cash equivalents and short-term investments, and through capital raising sources, which may be dilutive to existing stockholders.
• We currently estimate that as of June 30, 2025, we have sufficient cash, cash equivalents and short-term investments to fund operations for at least twelve months from the issuance of these financial statements.
• We will continue to maintain a full valuation allowance on our deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances. A release of the valuation allowance would result in the recognition of certain deferred tax assets and a corresponding income tax benefit in the period the release is recorded.

Industry Context

The biopharmaceutical industry is characterized by high R&D costs, stringent regulatory approvals, and intense competition. CorMedix's focus on DefenCath, the first and only FDA-approved antimicrobial catheter lock solution, positions it in a niche but critical market addressing catheter-related bloodstream infections. The acquisition of Melinta Therapeutics, with its focus on infectious diseases (REZZAYOTM for fungal infections, MINOCIN for minocycline), indicates a strategic expansion within the anti-infective space, aiming to diversify revenue streams beyond DefenCath. The industry is also subject to evolving reimbursement policies (NTAP, TDAPA, OPPS) and global trade policies, which can significantly impact profitability and supply chains.

Comparison to Industry Standards

• DefenCath's efficacy: The 71% reduction in CRBSI risk in a Phase 3 study for DefenCath is a strong clinical outcome, potentially positioning it as a leading solution in its specific indication compared to existing off-label or less effective alternatives.
• Reimbursement mechanisms: The securing of NTAP, TDAPA, and OPPS pass-through status for DefenCath is crucial for market adoption and revenue generation, aligning with best practices for new drug launches in the U.S. healthcare system to ensure favorable reimbursement.
• Acquisition strategy: The acquisition of Melinta Therapeutics, a company with commercialized products like MINOCIN and a late-stage asset like REZZAYOTM, is a common strategy in the biopharma industry for growth and portfolio diversification, similar to how larger pharmaceutical companies acquire smaller biotechs to gain access to new therapies and market segments.

Corporate Governance

Legal Proceedings

• In re CorMedix Inc. Securities Litigation (Case No. 2:21-cv-14020): Consolidated class action alleging violations of Sections 10(b) and 20(a) of the Exchange Act and Sections 11 and 15 of the Securities Act, related to alleged false/misleading statements regarding DefenCath NDA submissions and FDA communications. The Court initially denied the motion to dismiss on June 30, 2025, but withdrew the opinion on July 23, 2025, citing error, with a new opinion to follow. Discovery deadlines have been set.
• In re CorMedix Inc. Derivative Litigation (Case No. 2:21-cv-18493): Consolidated shareholder derivative complaints alleging breaches of fiduciary duties, abuse of control, waste of corporate assets, and unjust enrichment against current and former directors/officers. The case is currently stayed pending resolution of the securities class action motion to dismiss. Derivative plaintiffs have until September 15, 2025, to file a consolidated complaint.

Stakeholder Impact

• Shareholders: Significant increase in revenue and net income, potential for growth through Melinta acquisition, but also dilution from recent public offering and convertible notes, and ongoing litigation risks.
• Employees: Potential uncertainty and disruption due to the Melinta acquisition, with a risk of loss of key personnel.
• Customers: Continued access to DefenCath with favorable reimbursement mechanisms; potential for expanded product offerings with Melinta's portfolio.
• Suppliers: Continued reliance on third-party manufacturers, with efforts to qualify alternate suppliers for key Active Pharmaceutical Ingredients (APIs).
• Creditors: New $150 million convertible senior notes will increase debt obligations, but proceeds are for strategic acquisition.

Next Steps

• Completion of Melinta Therapeutics acquisition, expected in September 2025.
• Issuance of $150 million convertible senior notes on August 12, 2025.
• Assessment of the full quantitative impact of the 'One Big Beautiful Bill Act' on income tax expense, deferred tax assets/liabilities, and cash flows in Q3 2025.
• Continued commercialization and market penetration of DefenCath in inpatient and outpatient settings.
• Potential qualification of an alternate third-party supplier for heparin sodium API within the next twelve months.
• Resolution of ongoing securities and derivative litigation, including the filing of a consolidated complaint by derivative plaintiffs by September 15, 2025, and a new opinion from the Court on the motion to dismiss the securities class action.
• Integration of Melinta's business and realization of anticipated synergies.

Key Dates

Recommendation

The company has demonstrated a remarkable turnaround, achieving significant revenue growth and profitability driven by the successful commercial launch of DefenCath. The strategic acquisition of Melinta Therapeutics, coupled with new financing, positions the company for substantial portfolio expansion and diversified revenue streams in the anti-infective market. While legal proceedings and integration risks exist, the strong financial performance, positive cash flow from operations, and clear strategic direction suggest a robust growth trajectory. The favorable tax law changes further enhance the financial outlook.
