KVYO Stock Forecast & Price Target

Klaviyo is supported by strong core demand, with revenue of $370.6M in 2Q growing 26.4% year over year, 205K total customers, and 9K net adds, while larger customers grew ARR 36% and now account for about 40% of ARR. Its value proposition is deepening as personalization-related data and analytics ARR is up 100% year over year, multi-product customers retain better, and new AI products like Composer and Customer Agent are showing early adoption and monetization traction. Despite some gross margin pressure from SMS and carrier fees, the company’s international revenue growth of 34.7% year over year and continued up-market wins suggest durable expansion and a broader platform opportunity.

Klaviyo is facing several fundamental headwinds that support a negative outlook, including a 300 bps year-over-year gross margin decline from a higher mix of lower-margin text messages and elevated carrier fees, with the carrier fee pass-through only gradually taking effect as contracts renew. Profitability also looks pressured, as the 2026 EBIT guide of $10 million is being reduced by a $10 million to $12 million headwind from the Agency M&A deal, which appears to add little revenue while bringing dilution risk from stock-based compensation and higher cash compensation. On top of that, the company’s heavy reliance on partner-driven customer acquisition, SMB and mid-market exposure, competitive pricing pressure, and month-to-month contract structure create weaker revenue visibility and greater churn risk.
