What this transaction means for investors

The May 18 stock sale by Klaviyo Board of Directors member Susan St. Ledger is not a cause for investor concern. She executed the transaction as part of a Rule 10b5-1 trading plan, adopted in June of 2025.

A Rule 10b5-1 trading plan is often used by insiders to avoid accusations of trading on insider information. In addition, she still holds nearly 11,000 Series A shares and over 50,000 Series B Common Stock, which can be converted into Series A. This suggests she is not in a rush to dispose of her holdings.

The sale came at a time when Klaviyo stock was down, dropping to a 52-week low of $13.53 on May 13, just days before St. Ledger’s transaction. Like many SaaS stocks, Klaviyo was impacted by a sector-wide sell-off as Wall Street became fearful that artificial intelligence would strip SaaS companies of their business. Shares were also impacted by the departure of its CFO.

In Klaviyo’s case, AI does not appear to be affecting results. The company reported first-quarter revenue of $358 million, a strong 28% year-over-year increase. Thanks to its excellent performance to start the year, Klaviyo raised its full-year 2026 sales guidance to $1.5 billion, which represents year-over-year growth of 23%.

Because its stock is down, Klaviyo’s price-to-sales ratio of three is around a low point for the past year. This suggests now is a good time to buy shares but not to sell.
