Rhea-AI Filing Summary

Neurocrine Biosciences completed its all-cash acquisition of Soleno Therapeutics for approximately $2.9 billion. The deal was executed via a tender offer at $53.00 per Soleno share, followed by a short-form merger that makes Soleno a wholly owned subsidiary.

As of the offer expiration, 46,356,114 Soleno shares had been validly tendered, representing 88.9% of Soleno’s outstanding stock. The acquisition adds VYKAT XR, the first approved treatment for hyperphagia in Prader-Willi syndrome, to Neurocrine’s commercial portfolio alongside INGREZZA and CRENESSITY.

On May 14, 2026, Neurocrine also entered into a five-year senior secured revolving credit facility of $1.0 billion and made an initial borrowing of $600.0 million under this facility, which is secured by substantially all of the company’s and certain subsidiaries’ assets.

Positive

  • Completion of strategic rare-disease acquisition: Neurocrine closed the approximately $2.9 billion cash purchase of Soleno Therapeutics, adding VYKAT XR, the first and only approved treatment for hyperphagia in Prader-Willi syndrome, to its commercial portfolio alongside INGREZZA and CRENESSITY.

Negative

  • Higher financial commitments and new secured debt: The Soleno acquisition required approximately $2.9 billion in cash and coincides with a new $1.0 billion senior secured revolving credit facility, of which $600.0 million was borrowed initially, increasing leverage constraints under defined covenant ratios.

Insights

Neurocrine makes a major rare-disease acquisition and adds new committed debt capacity.

Neurocrine Biosciences has closed its acquisition of Soleno Therapeutics for approximately $2.9 billion in cash at $53 per share, after securing 88.9% of Soleno shares in a tender offer and completing a follow-on merger under Section 251(h) of Delaware law.

The transaction brings VYKAT XR, the first approved treatment for hyperphagia in Prader-Willi syndrome, into Neurocrine’s portfolio alongside existing neurology and endocrine assets. Strategically, this expands the company’s presence in rare endocrine disease with a commercial-stage product targeting an estimated 10,000 U.S. patients with Prader-Willi syndrome.

To support financial flexibility, Neurocrine entered a five-year, senior secured revolving credit facility of $1.0 billion and drew $600.0 million initially. Covenants include a maximum total net leverage ratio of 3.75:1.00 and a minimum interest coverage ratio of 2.00:1.00, which will influence future balance sheet capacity as integration and commercialization progress.

Commitment fee rate 0.10%–0.25% per annum Fee on daily unused portion of revolving facility
tender offer financial
"commenced a tender offer to purchase all the outstanding shares of Soleno’s common stock"
A tender offer is a proposal made by a person or company to buy shares from existing shareholders at a set price, usually higher than the current market value, within a specific time frame. It matters to investors because it can lead to a change in ownership or control of a company, and shareholders must decide whether to sell their shares at the offered price.
senior secured revolving credit facility financial
"provides for a five-year, $1.0 billion senior secured revolving credit facility"
A senior secured revolving credit facility is a multi‑use bank lending line that a company can draw, repay and redraw as needed, backed by specific assets and ranked first in repayment order if the company defaults. Think of it like a collateralized credit card that gives flexible short‑term cash while lenders hold priority to recover their money; investors watch it because it affects a company’s liquidity, borrowing cost, and who gets paid first in financial distress.
total net leverage ratio financial
"a maximum total net leverage ratio of 3.75:1.00"
Total net leverage ratio measures how much a company owes after using its cash, compared with the cash it generates in a year; it is usually calculated by subtracting cash from total debt and dividing that net debt by annual operating cash flow or earnings. Investors use it like a debt-to-income check for a household — a higher number means the company may struggle to cover obligations and is riskier, while a lower number suggests more cushion and financial flexibility.
interest coverage ratio financial
"a minimum consolidated interest coverage ratio of 2.00:1.00"
A measure of how easily a company can pay the interest on its debt, calculated by comparing the earnings it generates from operations to the interest it owes. It matters to investors because a higher ratio means the company can comfortably meet interest payments — like having several paychecks set aside to cover your rent — while a low ratio signals greater risk of missed payments or financial strain.
Prader-Willi syndrome medical
"the first and only approved medicine for hyperphagia in adults and pediatric patients ... with Prader-Willi syndrome"
A rare genetic disorder caused by missing or altered instructions on a specific chromosome that leads to constant hunger, low muscle tone, learning challenges, and hormonal problems; think of it as a faulty instruction manual that affects growth, appetite control, and development. Investors care because the condition creates a defined patient population, special regulatory incentives, and long-term medical needs that shape demand for therapies, diagnostics, and care services, influencing market size and risk for drug developers.
Section 251(h) regulatory
"pursuant to Section 251(h) of the General Corporation Law of the State of Delaware"
Section 251(h) is a provision in Delaware corporate law that lets a company complete a merger without holding a separate shareholder vote if a prior, qualifying tender offer already secured the required number of shares on the same terms. For investors, it matters because it shortens the timetable and reduces the risk that a merger will be blocked by a follow-up vote—think of it as a shortcut that finalizes a deal once enough stockholders have already agreed.

Introductory Note

As previously disclosed in the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) by Neurocrine Biosciences, Inc., a Delaware corporation (the “Company”), on April 6, 2026, the Company entered into an Agreement and Plan of Merger, dated as of April 5, 2026 (the “Merger Agreement”), with Sigma Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Purchaser”), and Soleno Therapeutics, Inc., a Delaware corporation (“Soleno”). Pursuant to the Merger Agreement, on April 20, 2026, the Company, through Purchaser, commenced a tender offer to purchase all the outstanding shares of Soleno’s common stock, par value $0.001 per share (the “Soleno Shares”), at a price of $53.00 per Soleno Share (the “Offer Price”), in cash, without interest and subject to any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated April 20, 2026 (together with any amendments or supplements thereto, the “Offer to Purchase”) and in the related Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal”; the Offer to Purchase and the Letter of Transmittal, collectively, the “Offer”). The Offer to Purchase and the Letter of Transmittal were filed as Exhibits (a)(1)(A) and (a)(1)(B), respectively, to the Tender Offer Statement on Schedule TO originally filed with the SEC by Purchaser and the Company on April 20, 2026.

 

Item 1.01.

Entry into a Material Definitive Agreement.

The information set forth in Item 2.03 of this Current Report on Form 8-K (this “Report”) is incorporated by reference into this Item 1.01.

 

Item 2.01.

Completion of Acquisition or Disposition of Assets.

The information set forth in the Introductory Note of this Report is incorporated by reference into this Item 2.01.

The Offer and related withdrawal rights expired as scheduled at one minute following 11:59 p.m. Eastern time on May 15, 2026 (such date and time, the “Expiration Date”). Purchaser was advised by Equiniti Trust Company, LLC, the depositary for the Offer, that as of the Expiration Date, a total of 46,356,114 Soleno Shares had been validly tendered (and not validly withdrawn) pursuant to the Offer, representing approximately 88.9% of the issued and outstanding Soleno Shares as of the Expiration Date. As of the Expiration Date, the number of Soleno 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 or waived. Promptly after the Expiration Date, Purchaser irrevocably accepted for payment all Soleno Shares validly tendered and not validly withdrawn pursuant to the Offer and payment of the Offer Price for such Soleno Shares will be made promptly in accordance with the terms of the Offer and the Merger Agreement.

The Company completed the acquisition of Soleno on May 18, 2026, by causing Purchaser to merge with and into Soleno (the “Merger”) pursuant to the Merger Agreement without any action by Soleno stockholders in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”). At the effective time of the Merger (the “Effective Time”), Purchaser was merged with and into Soleno, the separate existence of Purchaser ceased and Soleno continued as a direct wholly owned subsidiary of the Company.

At the Effective Time, each Soleno Share issued and outstanding immediately prior to the Effective Time (other than (i) Soleno Shares owned immediately prior to the Effective Time by Soleno (including those held in Soleno’s treasury), (ii) Soleno Shares owned both as of the commencement date of the Offer and immediately prior to the Effective Time by the Company, Purchaser, or any other direct or indirect wholly owned subsidiary of the Company, (iii) Soleno Shares irrevocably accepted by Purchaser for purchase pursuant to the Offer and (iv) Soleno Shares held by stockholders who have properly exercised and perfected their demands for appraisal of such Soleno Shares in accordance with the DGCL and have neither withdrawn nor lost such rights prior to the Effective Time) was canceled and ceased to exist and was converted into the right to receive the Offer Price, without interest and subject to any required withholding of taxes.

 

2


In addition, pursuant to the terms of the Merger Agreement, effective as of immediately prior to the Effective Time, by virtue of the Merger, without any action on the part of Soleno, the Company, Purchaser or the holder thereof:

(i) each option to purchase Soleno Shares (each, a “Soleno Option”) that was outstanding and unexercised as of immediately prior to the Effective Time and that did not have an exercise price per Soleno Share that was equal to or greater than the Offer Price, whether or not then vested or exercisable, was canceled and converted into the right to receive an amount in cash, without interest and subject to any applicable withholding taxes, equal to (x) the total number of Soleno Shares subject to such Soleno Option immediately prior to such cancellation multiplied by (y) the excess, if any, of (A) the Offer Price over (B) the exercise price payable per Soleno Share underlying such Soleno Option;

(ii) each Soleno Option that was outstanding and unexercised as of immediately prior to the Effective Time and that did have an exercise price per Soleno Share that was equal to or greater than the Offer Price, whether or not then vested or exercisable, was canceled and no holder thereof was entitled to any payment with respect to such Soleno Option before or after the Effective Time; and

(iii) each restricted stock unit award with respect to Soleno Shares (each, a “Soleno RSU Award”) that was outstanding immediately prior to the Effective Time, whether or not then vested, vested fully and was canceled and converted into the right to receive an amount in cash, without interest and subject to any applicable withholding taxes, equal to (x) the number of Soleno Shares subject to such Soleno RSU Award immediately prior to such cancellation multiplied by (y) the Offer Price.

All amounts payable to current or former Soleno employees with respect to Soleno Options and Soleno RSU Awards will be paid as soon as reasonably practicable after the Effective Time (but no later than fifteen (15) days after the Effective Time) and will be subject to deduction for any required tax withholding.

The Soleno Shares underlying all warrants to purchase Soleno Shares (“Soleno Warrants”) that were exercised prior to the Effective Time were treated in the same manner as each Soleno Share outstanding immediately prior to the Effective Time. All Soleno Warrants that were outstanding and unexercised immediately prior to the Effective Time, whether vested or unvested, were treated as being simultaneously cashless exercised as of immediately prior to the Effective Time, subject to deduction for any required withholding taxes, in accordance with the terms and conditions specified in the applicable Soleno Warrant and the related warrant termination agreements between Soleno and the respective holders of the Soleno Warrants.

The aggregate cash paid by the Company and Purchaser in the Offer and the Merger was approximately $2.9 billion, plus related fees and expenses, which was funded by the Company from its available cash on hand.

The foregoing summary of the Offer, the Merger, the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was previously filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the SEC on April 6, 2026, and incorporated herein by reference.

 

Item 2.03.

Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On May 14, 2026 (the “Closing Date”), the Company entered into a credit agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and collateral agent (in such capacities, the “Agent”), and the lenders party thereto. The Credit Agreement provides for a five-year, $1.0 billion senior secured revolving credit facility (the “Revolving Credit Facility”).

Interest rates under the Revolving Credit Facility are variable and equal to, at the Company’s option, (i) Term SOFR (as defined in the Credit Agreement), plus a margin of 1.125% to 1.75% per annum, or (ii) an alternate base rate plus a margin of 0.125% to 0.75% per annum, in each case based on the lower of the applicable rates determined by reference to the Company’s total secured net leverage ratio and credit ratings from time to time.

The Company will pay customary agency fees and a commitment fee based on the daily unused portion of the Revolving Credit Facility at a rate of 0.10% to 0.25% per annum based on the lower of the applicable rates determined by reference to the Company’s secured net leverage ratio and credit ratings from time to time. The Revolving Credit Facility is not subject to amortization and will mature on the fifth anniversary of the Closing Date.

On the Closing Date, the Company entered into a pledge and security agreement, pursuant to which the Company granted to the Agent, for the benefit of the lenders under the Credit Agreement, a security interest in substantially all of its assets, subject to customary exceptions and exclusions. Any material domestic subsidiaries of the Company in existence from time to time will be required to guarantee the Company’s obligations under the Credit Agreement and grant to the Agent, for the benefit of the lenders, a security interest in substantially all of their assets, subject to customary exceptions and exclusions.

The Credit Agreement contains customary representations and warranties, affirmative covenants, negative covenants and events of default. The Credit Agreement also contains financial covenants that are tested on the last day of each of the Company’s fiscal quarters. These financial covenants include (x) a maximum total net leverage ratio of 3.75:1.00 (which may, at the Company’s election, increase to 4.25:1.00 for certain periods following certain material acquisitions or investments by the Company), and (y) a minimum consolidated interest coverage ratio of 2.00:1.00. On the Closing Date, the Company made an initial borrowing of $600.0 million under the Revolving Credit Facility.

The foregoing description of the Credit Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Credit Agreement, attached hereto as Exhibit 10.1 and incorporated herein by reference.

Exhibit 99.1

Neurocrine Biosciences Completes Acquisition of Soleno Therapeutics

 

   

Strengthens Neurocrine’s rare disease portfolio with VYKAT XR, the first and only approved treatment for hyperphagia in Prader-Willi syndrome

 

   

Adds recently launched therapy with strong early adoption and meaningful commercial potential

SAN DIEGO, May 18, 2026 – Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the completion of its acquisition of Soleno Therapeutics, Inc., strengthening the company’s leadership in endocrinology and rare disease. The acquisition adds VYKAT XR (diazoxide choline) tablets, the first and only approved medicine for hyperphagia in adults and pediatric patients 4 years of age and older with Prader-Willi syndrome, to Neurocrine’s first-in-class commercial portfolio alongside INGREZZA® (valbenazine) and CRENESSITY® (crinecerfont).

“Today marks an important advancement in Neurocrine’s mission to deliver life-changing treatments for patients with significant unmet needs,” said Kyle W. Gano, Ph.D., Chief Executive Officer, Neurocrine Biosciences. “We welcome our Soleno colleagues to Neurocrine and share their deep commitment to the Prader-Willi syndrome community, and we look forward to working together to make VYKAT XR available to more patients and their families.”

Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder caused by an abnormality in gene expression on chromosome 15 that affects about 10,000 patients in the United States. The disease is characterized by neurological, behavioral, and metabolic dysfunction. Its defining feature is hyperphagia, a chronic, life-threatening condition marked by a persistent hunger that drives compulsive, food-seeking behavior. Individuals with PWS also commonly experience cognitive impairment and a range of psychiatric and behavioral challenges. Together, these symptoms can severely diminish quality of life for individuals with PWS and their families, with hyperphagia driving significant morbidity and mortality.

Neurocrine initially announced the transaction – representing a total equity value of $2.9 billion – on April 6, 2026.

Transaction Details

Neurocrine completed the cash tender offer through a subsidiary for all the outstanding shares of common stock of Soleno at a purchase price of $53.00 per share, without interest, subject to any applicable withholding taxes.


As of the tender offer expiration at one minute after 11:59 p.m. EDT on May 15, 2026, 46,356,114 shares of Soleno common stock were validly tendered and not validly withdrawn, representing approximately 88.9% of the total number of Soleno’s issued and outstanding shares of common stock as of such date and time. In accordance with the terms of the tender offer, all such shares have been accepted for payment.

Following its acceptance of the tendered shares, Neurocrine completed its acquisition of Soleno through the merger of a direct wholly owned subsidiary of Neurocrine with and into Soleno, pursuant to Section 251(h) of the Delaware General Corporation Law on May 18, 2026, with Soleno continuing as the surviving corporation and becoming a direct, wholly owned subsidiary of Neurocrine. All remaining shares of Soleno common stock that were not validly tendered in the tender offer were converted into the right to receive the same $53 per share in cash, without interest, subject to any applicable withholding taxes, that would have been paid had such shares been validly tendered in the tender offer. As of May 18, 2026, Soleno’s common stock will no longer be listed or traded on the Nasdaq Capital Market.

Advisors

Goldman Sachs & Co. LLC served as exclusive financial advisor, and Cooley LLP served as legal advisor to Neurocrine. Centerview Partners LLC and Guggenheim Securities, LLC served as financial advisors, and Wilson Sonsini Goodrich & Rosati, Professional Corporation served as legal counsel to Soleno.

About PWS

Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder caused by an abnormality in gene expression on chromosome 15. The Prader-Willi Syndrome Association USA estimates that PWS occurs in one in every 15,000 live births. The defining symptom of PWS is hyperphagia, a chronic and life-threatening condition characterized by an intense persistent sensation of hunger accompanied by food preoccupations, an extreme drive to consume food, food-related behavior problems, and a lack of normal satiety, which can severely diminish the quality of life for individuals with PWS and their families. Hyperphagia can lead to significant mortality (e.g., stomach rupture, choking, accidental death due to food seeking behavior) and longer-term co-morbidities such as diabetes, obesity, and cardiovascular disease.
