Rhea-AI Filing Summary

Assertio Holdings, Inc. CEO Mark L. Reisenauer reported the disposition of all his reported equity interests in connection with Assertio’s cash merger with an affiliate of Zydus. A tender offer acquired all outstanding Assertio common shares at $23.50 per share in cash, after which the merger closed.

The filing shows 3,583 common shares cancelled and converted into the right to receive cash. In addition, 33,333 restricted stock units became fully vested immediately before the merger and were then cancelled for a cash payment per unit equal to the $23.50 offer price.

Stock options with exercise prices below the offer price, including 26,667 options at $11.77, 66,666 options at $12.372, and 5,415 options at $12.7515, were cancelled and converted into cash equal to the spread between $23.50 and the respective exercise prices, multiplied by the optioned shares. Options with exercise prices at or above $23.50 were cancelled without payment. Following these transactions, the Form 4 reports zero common shares, stock options, or RSUs remaining for the CEO.

Insights

CEO’s equity is cashed out in a completed cash merger.

This Form 4 reflects mechanical clean-up of equity awards as Assertio is acquired for cash at $23.50 per share. The CEO’s common shares, in-the-money options, and RSUs are all cancelled and converted into cash rights under the merger agreement.

The transactions use codes U and D, indicating a tender-offer-related disposition and returns to the issuer, not open-market buying or selling. Afterward, the filing shows zero remaining equity or derivatives, consistent with Assertio becoming a wholly owned subsidiary. The market impact comes from the merger itself; this Form 4 mainly documents how executive equity was settled.

tender offer financial
"Purchaser completed a tender offer (the "Offer") for all outstanding shares"
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.
Reverse Stock Split financial
"the Issuer effected a 1-for-15 reverse stock split (the "Reverse Stock Split")"
A reverse stock split is when a company reduces the number of its shares outstanding, making each share more valuable. For example, if you own 100 shares worth $1 each, a 1-for-10 reverse split would turn your 100 shares into 10 shares worth $10 each. Companies often do this to boost their stock price and appear more stable to investors.
Restricted Stock Units financial
"each restricted stock unit of the Issuer (each, a "Company RSU")"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Agreement and Plan of Merger financial
"pursuant to the Agreement and Plan of Merger (the "Merger Agreement")"
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.
Offer Price financial
"at a price of $23.50 per share in cash, without interest (the "Offer Price")"
The offer price is the amount per share that a company or underwriter sets when selling new stock or bonds to investors, like the price tag on an item in a store. It matters because it determines how much investors must pay, shapes the initial market value of the security, and influences whether demand will be strong or weak — which affects early trading performance and potential returns.
