Klaviyo's chief financial officer, Amanda Whalen, has sold $248,500 (£191,000) worth of shares in the marketing automation company, according to a filing with the US Securities and Exchange Commission. The transaction, which took place on 16 July 2026, involved the sale of 8,000 shares at an average price of approximately $31.06 each.
The sale was conducted under a pre-arranged trading plan, known as a 10b5-1 plan, which allows company insiders to sell shares at predetermined times to avoid accusations of trading on non-public information. Whalen retains a substantial holding in the company following the sale, the filing shows.
Klaviyo, which provides email and SMS marketing platforms for e-commerce businesses, has seen its stock price fall roughly 18% year-to-date as of 17 July 2026. The broader technology sector has been under pressure from persistent inflation and uncertainty over interest rate policy from the Federal Reserve, weighing on high-growth names.
For UK investors with exposure to US tech stocks through pension funds or ETFs, insider sales can sometimes signal a lack of confidence, though pre-arranged plans often reduce that interpretation. Analysts at several investment banks have maintained 'hold' ratings on Klaviyo, citing its strong revenue growth but cautious outlook on enterprise spending.
The e-commerce marketing software sector remains competitive, with rivals such as Salesforce and HubSpot also vying for market share. Klaviyo's next quarterly earnings report is expected in early August, which will provide further clarity on customer demand and margin trends.
