Executive Summary
The Delaware Superior Court granted summary judgment to US WorldMeds in a breach-of-contract suit against Supernus, ruling that Supernus improperly withheld a $30 million milestone payment related to an acquired infusion pump. The court held that the agreement's set-off provision requires a final, liquidated debt, which Supernus did not have based on pending fraud and antitrust litigation. Supernus must now pay the withheld amount plus interest and attorneys' fees, creating a material cash liability and adverse legal precedent.
Court Ruling Details
Key Facts
- Supernus purchased a portfolio of products from US WorldMeds in 2020 for $300 million upfront plus up to $230 million in milestone payments.
- A $30 million milestone payment became due in April 2025 after the first Infusion Pump sale.
- Supernus withheld $25,843,223.58 of the milestone payment, asserting a right of set-off based on pending litigation against US WorldMeds.
- The court ruled the set-off provision requires mutual, mature debts; Supernus's pending fraud and antitrust claims do not qualify.
- Supernus is ordered to pay the withheld amount plus pre- and post-judgment interest at the contractual rate (prime plus %) and attorneys' fees.
- US WorldMeds is to submit its fee application within 10 days; the court will determine the final amount.
Financial Impact
Supernus must pay approximately $25.8 million in withheld milestone payment plus interest and attorneys' fees; the exact fee amount is to be determined.
Risk Factors
- Immediate cash outflow of ~$25.8 million plus interest and attorneys' fees.
- Adverse legal precedent may weaken Supernus's position in the pending Delaware antitrust and Kentucky fraud cases.
- Potential for additional litigation costs if Supernus appeals the summary judgment ruling.
