SCPH tendered for $5.35 cash with up to $1.00 contingent payout

Rhea-AI Filing Summary

scPharmaceuticals, Inc. filed an amendment to its Schedule 14D-9 related to a tender offer by MannKind Corporation through its subsidiary, Seacoast Merger Sub, Inc., to acquire all outstanding shares for an Offer Price consisting of $5.35 cash per share plus one non-tradeable contingent value right (CVR) per share that can pay up to $1.00 in aggregate if certain regulatory and net sales milestones are met. The Offer materials (Offer to Purchase and Letter of Transmittal) were filed on September 8, 2025, and this amendment notes an updated exhibit: a Press Release by MannKind dated October 7, 2025 is incorporated by reference. The CVR payments are subject to milestone achievement and withholding taxes, and the CVR Agreement designates Broadridge as Rights Agent. The amendment states that capitalized terms carry the same meanings as in the Schedule 14D-9 and that the Schedule 14D-9 remains unchanged except for the exhibit update.

Positive

• Immediate cash consideration of $5.35 per share provides certain liquidity to holders
• Contingent upside of up to $1.00 per CVR ties additional payment to regulatory and net sales milestones
• Clear documentation filed: Offer to Purchase, Letter of Transmittal, Schedule 14D-9 and CVR Agreement identify terms and Rights Agent

Negative

• CVR is non-tradeable, so holders cannot sell the contingent right before payout
• CVR payouts are conditional on achieving regulatory and net sales milestones, creating uncertainty about receiving the additional $1.00
• Amendment only updates exhibits and does not change recommendation or material terms, limiting new protections or improved economics for holders

Insights

Corporate Finance Analyst

TL;DR: The transaction offers immediate cash plus contingent upside tied to regulatory and sales milestones.

The structure delivers $5.35 in cash per share plus a non-tradeable CVR providing up to $1.00 if specified regulatory and net sales milestones are met. This splits value between certain near-term cash and conditional future payments, which preserves liquidity for holders while linking additional consideration to development/commercial outcomes.

Key dependencies include the successful achievement of the disclosed milestones and the timelines specified in the CVR Agreement; because the CVR is non-tradeable, holders cannot monetize that contingent value before payouts. Monitor milestone deadlines and any reporting that quantifies progress toward regulatory approvals or sales thresholds over the next 12–36 months.

M&A / Securities Counsel

TL;DR: The amendment updates exhibits but leaves the recommendation language intact; legal terms place payout conditions on the CVR.

The amendment incorporates a October 7, 2025 MannKind press release as an exhibit and affirms that defined terms from the Schedule 14D-9 still apply. The Offer relies on the Offer to Purchase and Letter of Transmittal filed on September 8, 2025, and the CVR Agreement governs contingent payments through Broadridge as Rights Agent.

Risks include the conditional nature of CVR payments and potential withholding tax treatment. Stakeholders should review the CVR Agreement and the Offer documents for specific milestone definitions, outside dates, and any conditions to closing; these documents determine enforceability and timing of any contingent payouts.

The Offer is described in a Tender Offer Statement on Schedule TO (as amended, supplemented or otherwise modified from time to time, the “Schedule TO”) filed by Parent and Purchaser with the U.S. Securities and Exchange Commission (the “SEC”) on September 8, 2025.

Capitalized terms used, but not otherwise defined, in this Amendment shall have the meanings ascribed to them in the Schedule 14D-9. This Amendment is being filed to reflect certain updates as reflected below.

Item 8. Additional Information.

Item 8 of the Schedule 14D-9 is hereby amended and supplemented by adding the following new subsection before the final subsection entitled “Item 8. Additional Information”:

The Offer and related withdrawal rights expired as scheduled at one minute following 11:59 p.m., Eastern time, on October 6, 2025 (the “Expiration Date”). Purchaser was advised by Broadridge Corporate Issuer Solutions, LLC, the depositary for the Offer (the “Depositary”), that, as of the Expiration Date, a total of 39,933,692 Shares (excluding Shares with respect to which Notices of Guaranteed Delivery were delivered but were not yet “received” (as such term is defined in Section 251(h) of the DGCL)) had been validly tendered and not validly withdrawn pursuant to the Offer, representing approximately 73.47% of the outstanding Shares as of the Expiration Date. In addition, the Depositary has advised that, as of the Expiration Date, Notices of Guaranteed Delivery had been delivered with respect to 5,930,025 additional Shares, representing approximately 10.91% of the total outstanding Shares as of immediately prior to the Expiration Time.

As of the Expiration Date, the number of Shares validly tendered and not validly withdrawn pursuant to the Offer satisfied the Minimum Condition (as defined in the Merger Agreement), and all other conditions to the Offer were satisfied. Promptly after the Expiration Date, Purchaser irrevocably accepted for payment all Shares validly tendered and not validly withdrawn pursuant to the Offer and payment of the Offer Price for such Shares will be made promptly in accordance with the terms of the Offer and the Merger Agreement.

Promptly following the Expiration Date and Purchaser’s acceptance for payment of the Shares pursuant to the Offer, Parent and Purchaser completed the Merger on October 7, 2025 pursuant to the Merger Agreement without any action by the Company stockholders in accordance with Section 251(h) of the DGCL. At the Effective Time, Purchaser was merged with and into the Company, with the Company continuing as the Surviving Company and a direct wholly owned subsidiary of Parent. Each Share issued

Following the consummation of the Merger, the Shares will be delisted from The Nasdaq Global Select Market, and trading of Shares is expected to be halted effective prior to the open of trading on October 7, 2025. Parent and Purchaser intend to take steps to cause the termination of the registration of the Shares under the Exchange Act and suspend all of the Company’s reporting obligations under the Exchange Act as promptly as practicable.
