  1. A portion of these shares represent restricted stock units ("RSUs"). Each RSU represents a right to receive one share of the Issuer's common stock ("Common Stock") upon vesting. On April 28, 2026, pursuant to the terms of that certain Agreement and Plan of Merger (the "Merger Agreement"), dated as of November 18, 2025, by and among Semrush Holdings, Inc., a Delaware corporation (the "Issuer"), Adobe Inc., a Delaware corporation ("Parent"), and Fenway Merger Sub, Inc., a Delaware corporation and a direct, wholly owned subsidiary of Parent ("Merger Sub"), Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. At the effective time of the Merger (the "Effective Time"), each share of Common Stock held by the reporting person was converted into the right to receive $12.00 in cash (the "Merger Consideration"). At the Effective Time, each RSU award that was subject solely to service-based vesting requirements ("RSU Award") held by a non-employee director, contractors or other certain service providers (each, a "Specified Individual") was cancelled and cashed out for a payment equal to the Merger Consideration in respect of each underlying share and each other RSU award was converted into a restricted stock unit award relating to Parent common stock (an "Adobe RSU Award") in respect of a number of shares of Parent common stock obtained by multiplying the number of shares of Common Stock underlying the RSU Award by the quotient of (a) the Merger Consideration divided by (b) the closing price per share of Adobe common stock over the 30 consecutive calendar days ending on (and including) the second to last calendar day preceding the closing date (the "Adobe Trading Price"). At the Effective Time, each option to purchase shares of Common Stock ("Option") that is vested or is held by a Specified Individual was cancelled and cashed out for a payment equal to the excess of the Merger Consideration over the exercise price of such Option in respect of each underlying share and each unvested Option that is not held by a Specified Individual was converted into an Adobe RSU Award in respect of a number of shares of Parent common stock obtained by dividing the spread value of the Option by the Adobe Trading Price. Options with an exercise price equal to or greater than the Merger Consideration were cancelled for no consideration.

restricted stock units ("RSUs") financial
"A portion of these shares represent restricted stock units ("RSUs"). Each RSU represents a right to receive one share..."
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 terms of that certain Agreement and Plan of Merger (the "Merger Agreement"), dated as of November 18, 2025..."
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
"each share of Common Stock held by the reporting person was converted into the right to receive $12.00 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.
Effective Time regulatory
"At the effective time of the Merger (the "Effective Time"), each share of Common Stock held by the reporting person..."
Adobe RSU Award financial
"each other RSU award was converted into a restricted stock unit award relating to Parent common stock (an "Adobe RSU Award")..."
spread value of the Option financial
"was converted into an Adobe RSU Award in respect of a number of shares of Parent common stock obtained by dividing the spread value of the Option by the Adobe Trading Price."
