Rhea-AI Filing Summary

Soleno Therapeutics' Chief Commercial Officer, Meredith Manning, reported the cancellation of her equity in connection with Soleno’s merger with Neurocrine Biosciences. On May 18, 2026, all of her 64,507 shares of common stock were disposed of back to the issuer and converted into a cash payment.

Footnotes explain that, under the merger agreement, each share of common stock and each vested or unvested RSU was cancelled and converted into the right to receive $53.00 in cash per share. Several employee stock option grants were also cancelled in exchange for cash equal to the spread between $53.00 and their exercise prices, multiplied by the number of option shares.

After these issuer dispositions, the filing shows no remaining common stock or options for Manning from these reported awards, reflecting the change from equity in Soleno to cash consideration at closing of the merger.

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,"
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
"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.
