KVYO Stock Forecast & Price Target

Klaviyo is supported by durable core demand, with 3Q26 revenue of $379.3 million (+22.0% YoY) and FY26 revenue of $1,529.8 million (+24.0% YoY), while its platform continues to broaden beyond marketing into Service and Analytics. The bullish case is strengthened by strong multi-product and upmarket traction, including larger customers up 36% YoY, 20% of ARR from customers using 3+ products, and NRR of 109% that should reaccelerate after the current lapping headwind through 1Q27. Management also appears to be monetizing AI and international expansion effectively, as Composer reached 95K users in one month, Customer Agent adoption rose 40% sequentially in 2Q, and international revenue grew 34.7% YoY.

Klaviyo is facing a weaker fundamental setup because 1Q and 2Q both showed limited upside versus historical levels, while 2Q revenue growth of 26% was offset by gross margin pressure to 73%, roughly 200 bps below estimates. Management’s expectations for slightly lower 3Q gross margins, a greater-than-normal seasonal step-down in 4Q, and an exit rate near 68% imply continued margin compression, even after mobile pricing changes intended to neutralize carrier fees in FY26. Its heavy exposure to Entrepreneur and SMB customers, combined with intense competition from Salesforce, Adobe, Oracle, Braze, Attentive, and Iterable, heightens sensitivity to macro weakness and raises the risk of market share erosion.
