MannKind completes SCPH takeover: $5.35 cash plus $1.00 CVR per share

Rhea-AI Filing Summary

scPharmaceuticals Inc. agreed to be acquired by MannKind Corporation under a merger where each scPharmaceuticals share was purchased for $5.35 in cash plus one non-tradable contingent value right (CVR) that can pay up to $1.00 upon achieving specified regulatory and net‑sales milestones. The purchaser commenced a tender offer on September 8, 2025, and as of the offer expiration a total of 39,933,692 shares (about 73.47%) were validly tendered and 5,930,025 shares (about 10.91%) were delivered by guaranteed delivery.

The tender satisfied the Merger Agreement minimum condition, Purchaser accepted for payment the validly tendered shares, and the merger closed on October 7, 2025 by merging the purchaser into the company so the company became a direct wholly owned subsidiary of Parent. Outstanding employee equity with exercise prices below the cash amount were cashed out (net of exercise price), and restricted stock units were converted into cash equal to the cash amount plus one CVR per share; payments are to be made promptly and no later than 15 days after the effective time, subject to withholding.

Positive

• Acquisition completed with the company becoming a wholly owned subsidiary of MannKind
• Immediate cash consideration of $5.35 per share provided liquidity to shareholders
• Contingent upside preserved via one non-tradable CVR per share with up to $1.00 in aggregate payments
• Tender reached required threshold (~73.47% valid tenders) allowing prompt acceptance and closing

Negative

• CVR is non-tradable, so contingent payments cannot be sold separately prior to vesting
• Milestone-dependent payout of up to $1.00 is uncertain and contingent on regulatory and net-sales achievements
• Approximately 10.91% of shares were tendered via guaranteed delivery at expiration, introducing minor timing uncertainty before receipt
• Company independence ended as scPharmaceuticals became a subsidiary, removing public reporting as an independent issuer

Insights

M&A Strategist

Completed cash-and-CVR acquisition gives MannKind ownership while preserving milestone upside for former holders.

The transaction paid $5.35 in cash per share and issued one CVR per share that may deliver up to $1.00 upon meeting specified regulatory and net‑sales milestones, preserving contingent upside for sellers while providing immediate cash consideration.

Execution risk centers on the CVR milestones and timing; investors should note the CVR is non-tradable and payouts occur only if conditions are met by the outside dates specified in the CVR Agreement.

Corporate Finance Analyst

Tender results met the Merger Agreement threshold and the deal closed, triggering equity conversions and cash-outs for employees.

The Offer received valid tenders representing about 73.47% of outstanding shares with an additional 10.91% via guaranteed delivery, satisfying the Minimum Condition and enabling Purchaser to accept and pay promptly in accordance with the Offer and Merger Agreement.

Employee options with exercise prices below the cash amount were cashed out for the excess over exercise price and RSUs were cashed at the cash amount; these payments are subject to tax withholding and were to be made within 15 days of the Effective Time.
