[Form 4] SEMrush Holdings, Inc. Insider Trading Activity

Rhea-AI Filing Summary

SEMrush Holdings, Inc. director Anna Baird disposed of her Class A Common Stock in connection with the closing of the Adobe acquisition. On the April 28, 2026 merger effective time, her 44,518 shares were converted into the right to receive $12.00 per share in cash under the Agreement and Plan of Merger among SEMrush, Adobe and Fenway Merger Sub. Following this issuer disposition, she no longer held SEMrush common shares. Related restricted stock units were either cashed out at $12.00 per underlying share for certain non-employee director and service-provider awards or converted into Adobe RSU awards based on a formula using the $12.00 merger consideration and Adobe’s 30‑day closing-price average.

Director’s SEMrush shares were cashed out at $12 in Adobe’s closing.

This filing shows Anna Baird, a SEMrush director, had 44,518 Class A shares converted into the right to receive $12.00 per share when Adobe’s acquisition of SEMrush closed on April 28, 2026. The transaction is coded as a disposition to the issuer.

Footnotes explain that some holdings were restricted stock units, and that certain RSUs for non‑employee directors and specified service providers were cancelled and paid in cash, while other RSUs were converted into Adobe RSU awards using a formula tied to the $12.00 merger consideration and Adobe’s 30‑day average closing price.

After this event, the filing shows Baird held zero SEMrush shares directly, reflecting the transition of equity value into cash and, for some awards, into Adobe-based RSUs. The filing is primarily mechanical, documenting the equity treatment under the merger terms rather than a discretionary market trade.

restricted stock units ("RSUs") financial

"A portion of these shares represent 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 terms of that certain 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.

Merger Consideration financial

"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"),"

Adobe RSU Award financial

"was converted into a restricted stock unit award relating to Parent common stock (an "Adobe RSU Award")"
