Andrew Bialecki, co-chief executive officer of Klaviyo, Inc. (NASDAQ: KVYO), reported a sale of 206,827 shares of Series A common stock on March 10, 2026, generating approximately $4.1 million in proceeds. The transactions occurred across multiple trades with prices spanning $19.34 to $19.96 per share, according to a Form 4 filing with the Securities and Exchange Commission.
The sale was paired with a conversion: Bialecki also converted 206,827 Series A shares into Series B common stock, as disclosed in the same SEC filing. At the time of the disclosure, Klaviyo’s share price was quoted at $19.27, a level that reflects a 41% decline year-to-date.
Analysis cited from InvestingPro in the filing notes that, despite recent price weakness, the company could appear undervalued at current trading levels. The same InvestingPro source indicates that 16 analysts have raised earnings estimates for the upcoming period, a signal that consensus expectations among some sell-side analysts have been revised upward.
Concurrent with these insider transactions, Klaviyo announced a $500 million share repurchase program - the company’s first formal buyback initiative. The board authorized the program, which includes an immediate $100 million accelerated share repurchase and represents roughly 10% of Klaviyo’s market capitalization. The repurchase plan allows flexibility: the company may buy back Series A common stock through open-market operations as well as privately negotiated transactions.
William Blair analysts have commented that the buyback program signals confidence in Klaviyo’s outlook, according to the company disclosure. The buyback and the insider activity arrive as Klaviyo expands its technology partnerships: the company said it has entered into a strategic collaboration with Google aimed at enhancing AI-driven customer experiences by integrating Google’s search and AI capabilities with Klaviyo’s customer relationship management platform.
Klaviyo reported processing 3.4 billion daily customer interactions across more than 8 billion profiles as part of the description of its platform scale. The company framed the buyback and the Google partnership as elements of its broader efforts to solidify market positioning and deepen technological capabilities.
