This Amendment No. 5 ("Amendment No. 5") to the Tender Offer Statement on Schedule TO (together with any amendments and supplements thereto and the exhibits thereto, the "Schedule TO") amends and supplements the Tender Offer Statement originally filed on September 8, 2025 by MannKind Corporation, a Delaware corporation ("Parent"), and Seacoast Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Parent ("Purchaser"). This Amendment No. 5 and the Schedule TO relate to the offer by Purchaser to purchase all outstanding shares of common stock, par value $0.0001 per share (the "Company Shares"), of scPharmaceuticals Inc., a Delaware corporation (the "Company"), at a price of (i) $5.35 per Company Share, in cash (the "Cash Amount"), without interest, subject to any applicable withholding taxes, plus (ii) one non-tradable contingent value right (each, a "CVR") per Company Share, representing the right to receive certain contingent payments of up to an aggregate amount of $1.00 per CVR in cash, without interest, subject to any applicable withholding taxes, upon the achievement of certain regulatory and net sales milestones on or prior to the applicable milestone outside dates in accordance with the terms and conditions set forth in the Contingent Value Rights Agreement, entered into with Broadridge Corporate Issuer Solutions, LLC, a Pennsylvania limited liability company (the "Rights Agent"), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated September 8, 2025 (together with any amendments and supplements thereto, the "Offer to Purchase"), and in the related letter of transmittal (as it may be amended or supplemented from time to time, the "Letter of Transmittal") and in the related Notice of Guaranteed Delivery (as it may be amended or supplemented from time to time, the "Notice of Guaranteed Delivery" and which, together with the Offer to Purchase and the Letter of Transmittal, constitutes the "Offer"), copies of which are filed with the Schedule TO as Exhibits (a)(1)(i), (a)(1)(ii) and (a)(1)(iii), respectively.

Capitalized terms used, but not otherwise defined, in this Amendment No. 5 shall have the meanings ascribed to them in the Offer to Purchase. Except as set forth below, the information set forth in the Schedule TO remains unchanged and is incorporated herein by reference as relevant to the items in this Amendment No. 5.

***Items 1 through 9, and Item 11.***

The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented to include the following:

"The Offer and withdrawal rights expired as scheduled at one minute following 11:59 p.m. Eastern time, on October 6, 2025 (the "Expiration Date"). The Depositary has advised Purchaser that, as of the Expiration Date, 39,933,692 Company Shares (excluding any Company Shares tendered pursuant to guaranteed delivery procedures that have not yet been "received," as such term is defined by Section 251(h) of the DGCL) were validly tendered (and not validly withdrawn) pursuant to the Offer, representing approximately 73.47% of the total outstanding Company Shares as of the Expiration Date. In addition, Notices of Guaranteed Delivery had been delivered for 5,930,025 Company Shares, representing approximately 10.91% of the total outstanding Company Shares as of the Expiration Date. The number of Company Shares validly tendered (excluding any Company Shares tendered pursuant to guaranteed delivery procedures that have not yet been "received," as such term is defined by Section 251(h) of the DGCL) and not validly withdrawn pursuant to the Offer satisfies the Minimum Condition.

All conditions to the Offer having been satisfied, on October 7, 2025, Purchaser irrevocably accepted for payment all Company Shares validly tendered (and not validly withdrawn) prior to the Expiration Date, and payment of the Offer Price for such Company 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 Company Shares pursuant to the Offer, Parent and Purchaser consummated the Merger pursuant to the terms of the Merger Agreement and without any action by the stockholders of the Company 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 each Company Share that was issued and outstanding immediately prior to the Effective Time (other than Company Shares owned by Parent, Purchaser or the Company or by any of their respective subsidiaries (or held in the Company's treasury)) was cancelled and (other than any Dissenting Company Shares) was converted into the right to receive the Offer Price, without interest, subject to any applicable withholding of taxes. The Company Shares will no longer be listed on Nasdaq and will be deregistered under the Exchange Act.

**MannKind Completes Acquisition of scPharmaceuticals, Accelerating Revenue Growth in Cardiometabolic Care** 

**DANBURY, Conn., and BURLINGTON, Mass., October 7, 2025** (Globe Newswire) – **MannKind Corporation (Nasdaq: MNKD)** successfully completed the previously announced acquisition of scPharmaceuticals Inc.

The acquisition of scPharmaceuticals is expected to diversify and accelerate MannKind's double-digit revenue growth, driven by FUROSCIX<sup>®</sup> (furosemide injection)- an innovative therapy for edema due to chronic heart failure and chronic kidney disease. The transaction will strengthen MannKind's commercial and medical capabilities by integrating scPharmaceuticals' experienced team into its existing infrastructure. MannKind is positioned as a diversified, growth-focused biopharmaceutical company with its commercial assets—Afrezza<sup>®</sup>, FUROSCIX<sup>®</sup> and V-Go<sup>®</sup> — along with Tyvaso DPI<sup>®</sup>-related revenues, contributing to an annualized run rate of over $370 million based on Q2 2025 results. Additionally, the FUROSCIX ReadyFlow<sup>™</sup> Autoinjector supplemental New Drug Application (sNDA) filing was submitted as planned in Q3 2025.

"With the close of the acquisition, MannKind now has multiple revenue lines with strong growth potential, a deepening presence in cardiometabolic care, and a commercial infrastructure ready to support the next phase of growth," said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. "This milestone accelerates our strategy to build a patient-centric company that delivers innovative therapies for chronic disease."

The strategic fit between the two organizations creates meaningful growth opportunities, combining MannKind's endocrinology expertise and infrastructure with scPharmaceuticals' deep cardiovascular capabilities. MannKind is positioned to expand FUROSCIX's reach with nephrologists and cardiologists and to continue its success in chronic heart failure treatment. The potential for long-term value creation is further supported by MannKind's late-stage pipeline, including Inhaled Clofazimine for the treatment of nontuberculous mycobacterial lung disease and nintedanib DPI for the treatment of idiopathic pulmonary fibrosis.

**Transaction Details** 

The acquisition was structured as a tender offer to acquire all of the outstanding shares of scPharmaceuticals common stock at a price of $5.35 per share in cash plus one non-tradable contingent value right (CVR) per share to receive certain milestone payments of up to an aggregate of $1.00 per CVR in cash, for total consideration of up to $6.35 per share in cash. The non-tradable CVR is payable upon achieving certain regulatory and net sales milestones.

The tender offer expired at one minute following 11:59 p.m., Eastern Time, on October 6, 2025. The depositary for the tender offer advised MannKind and scPharmaceuticals that scPharmaceuticals stockholders holding approximately 73.47% of the outstanding shares of scPharmaceuticals common stock had tendered their shares, satisfying the minimum condition to consummate the tender offer. In addition, notices of guaranteed delivery were delivered for shares representing approximately 10.91% of the outstanding shares of scPharmaceuticals common stock. All of the conditions of the tender offer having been satisfied, MannKind accepted for payment all such tendered shares, and following a statutory merger under Section 251(h) of the Delaware General Corporation Law on October 7, 2025, scPharmaceuticals became a wholly owned subsidiary of MannKind. All remaining shares of scPharmaceuticals common stock that were not tendered in the tender offer were converted into the right to receive the same per share consideration as shares that were tendered in the tender offer, as described above.

With the completion of the transaction, shares of scPharmaceuticals' common stock, which traded on the Nasdaq under the symbol "SCPH," will cease trading as of today and will no longer be listed on the Nasdaq.

**INDICATION** 

FUROSCIX<sup>®</sup> (furosemide injection), 80 mg/10 mL for subcutaneous use is indicated for the treatment of edema (i.e., congestion, fluid overload, or hypervolemia) in adult patients with chronic heart failure or chronic kidney disease (CKD), including the nephrotic syndrome.

**IMPORTANT SAFETY INFORMATION** 

FUROSCIX is contraindicated in patients with anuria and in patients with a history of hypersensitivity to furosemide, any component of the FUROSCIX formulation, or medical adhesives.

Furosemide may cause fluid, electrolyte, and metabolic abnormalities, particularly in patients receiving higher doses, patients with inadequate oral electrolyte intake, and in elderly patients. Serum electrolytes, CO<sub>2</sub>, BUN, creatinine, glucose, and uric acid should be monitored frequently during furosemide therapy.

Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possibly vascular thrombosis and embolism, particularly in elderly patients.

Furosemide can cause dehydration and azotemia. If increasing azotemia and oliguria occur during treatment of severe progressive renal disease, discontinue furosemide.

Cases of tinnitus and reversible or irreversible hearing impairment and deafness have been reported with furosemide. Reports usually indicate that furosemide ototoxicity is associated with rapid injection, severe renal impairment, the use of higher than recommended doses, hypoproteinemia or concomitant therapy with aminoglycoside antibiotics, ethacrynic acid, or other ototoxic drugs.

In patients with severe symptoms of urinary retention (because of bladder emptying disorders, prostatic hyperplasia, urethral narrowing), the administration of furosemide can cause acute urinary retention related to increased production and retention of urine. These patients require careful monitoring, especially during the initial stages of treatment.

Contact with water or other fluids and certain patient movements during treatment may cause the On-body Infusor to prematurely terminate infusion. Ensure patients can detect and respond to alarms.

The most common adverse reactions with FUROSCIX administration in clinical trials were site and skin reactions including erythema, bruising, edema, and injection site pain.
