SimilarWeb CEO's Share Sales and the Duplicate-Report Correction

According to the filing, Or Offer, the Chief Executive Officer of SimilarWeb Ltd., sold a total of 79,591 ordinary shares across two trading days. On September 14, 2026, 52,900 shares were disposed of at a weighted average price of $8.5378 per share, in multiple transactions ranging from $8.07 to $8.70. The following day, September 15, 2026, an additional 26,691 shares were sold at a weighted average price of $8.5267, with individual prices ranging from $8.32 to $8.70. Both disposals are coded as "S" (sale) transactions and are listed as directly owned. Following the two sales, the filing reports that Offer holds 4,253,500 ordinary shares directly.

The primary purpose of this amended filing, designated as a Form 4/A, is administrative clarification rather than the reporting of new activity. The filing states that the same transactions "were inadvertently reported twice," referencing accession numbers 0001976408-26-000849 and 0001976408-26-000850. The amendment specifies that the duplicate report should be disregarded and that only one set of transactions occurred as described herein. Both sales were made under a Rule 10b5-1 trading plan that the reporting person adopted on June 1, 2026. SimilarWeb Ltd. is a digital intelligence company whose ordinary shares trade on the New York Stock Exchange under the symbol SMWB. The filing was signed by Meirav Shemesh on behalf of Oppenheimer Israel, acting as attorney-in-fact, on September 16, 2026.
