  1. Certain of these shares are represented by previously reported restricted stock units ("RSUs"). Pursuant to the Agreement and Plan of Merger, dated as of April 5, 2026, by and among Soleno Therapeutics, Inc. (the "Company"), Neocrine Biosciences, Inc. ("Parent") and Sigma Merger Sub, Inc. ("Merger Sub"), on May 18, 2026, Merger Sub merged with and into the Company (the "Merger"), with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent. In connection with the Merger, each issued and outstanding vested and unvested RSU was cancelled and converted into the right to receive an amount equal to $53.00 in cash (the "Merger Consideration"). In connection with the Merger, each issued and outstanding share of the Company's Common Stock was cancelled and converted into the right to receive an amount in cash equal to the Merger Consideration. At the effective time of the Merger, this option was cancelled in exchange for a cash payment equal to (x) the difference between the Merger Consideration and the per share exercise price of the option, multiplied by (y) the number of shares covered by the option as of immediately prior to such cancellation.

restricted stock units ("RSUs") financial
"Certain of these shares are represented by previously reported restricted stock units ("RSUs")."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger, dated as of April 5, 2026, by and among Soleno Therapeutics, Inc."
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
Merger Consideration financial
"was cancelled and converted into the right to receive an amount equal to $53.00 in cash (the "Merger Consideration")."
Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.
wholly owned subsidiary financial
"with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent."
A wholly owned subsidiary is a company whose entire ownership is held by another company (the parent), so the parent controls decisions, operations, and finances. Think of it as a fully controlled branch that runs as its own legal entity but whose results flow straight into the parent’s financial statements; investors watch these structures because they affect consolidated revenue, risk exposure, and how profits, liabilities, and cash flow are allocated across the corporate group.
