Klaviyo Shares Jump 10% on Multiyear Partnership With Atlassian Williams F1 Team

3-line summary

• Marketing software company Klaviyo announced a multiyear partnership to become the Atlassian Williams F1 Team's official B2C CRM partner starting in 2027, with its brand to appear on the team's FW50 race car, team uniforms, and drivers' race suits; shares rose 10.5% in premarket trading.
• The announcement is seen as reversing negative sentiment after Goldman Sachs downgraded Klaviyo on October 16 from buy to neutral with a $20 price target, citing reduced visibility on the timing and scale of new growth drivers such as AI agents; the broader market was weak premarket (S&P 500 futures -0.15%, Nasdaq -0.48%), with the move attributed to company-specific news rather than sector trends.
• No financial terms of the partnership were disclosed; Klaviyo reports third-quarter earnings on November 4, 2026. Ahead of the announcement, Stifel maintained a buy rating with a $22 target on October 14, while the broader 22-analyst consensus is "Moderate Buy" with an average 12-month price target of $26.86.
