This "sell to cover" transaction in order to satisfy tax obligations does not represent a discretionary transaction by the Reporting Person. The price reflected is the average price per share for the transactions that are aggregated and reported on the line. Shares ranged in price from $3.85 to $3.86. The Reporting Person will provide to the Commission, the issuer and any stockholder, upon request, full information regarding the number of shares purchased or sold at each separate price. On August 17, 2026, the Reporting Person filed a Form 4 that contained a scrivener's error that resulted in the number of shares beneficially owned directly by the Reporting Person to be overstated by 3 shares. This Form 4 corrects the amount of securities beneficially owned after the reported transaction as 35,753. Mr. Rennick is the Vice President, General Counsel, and Corproate Secretary of Informa TechTarget. /s/ Charles D. Rennick 2026-08-25
