Klaviyo came into this print as a fast growing marketing automation stock with a reputation for pairing software scale with improving profitability. The market looked past that on the day. The share price fell about 13% to US$16.73 after the Q2 release.

The headline is simple. Revenue reached US$370.6m while non GAAP operating income landed at US$50.9m. Management raised full year revenue guidance but trimmed the profit outlook as it leans harder into product and the Agency acquisition. The rest of the quarter’s story sits inside that trade off.

Is Klaviyo now a rare growth stock trading at a discount, or is the lower P/S multiple a sign the market sees something in the Q2 loss that headlines miss? See how the cash flow assumptions, peer multiples and that one off $4.2m loss stack up inside the valuation analysis for Klaviyo

Klaviyo’s AI CRM Story Meets Concrete Milestones

The bullish view on Klaviyo is that an AI native, vertically integrated B2C CRM can win larger customers, support more channels and still keep healthy margins. Q2 shows that this playbook is starting to appear in the numbers. Revenue grew 26% year on year to US$370.6m while non GAAP operating margin held at 13.7%, so heavier AI and infrastructure spend has not erased profitability.

The thesis also leans on deeper adoption of AI agents and multiproduct usage. Composer already has more than 95,000 users, with around a quarter using it weekly, and conversion of Composer generated campaigns into live campaigns has improved from 35% to 46%. Larger customers paying US$50k or more in annual recurring revenue grew 36% year on year to 4,477 and now make up about 40% of ARR, which supports the claim that Klaviyo’s broader platform is gaining traction with bigger budgets.

Compare Klaviyo’s customer wins and AI adoption with what the recent 13% share price drop suggests institutions are pricing in. See the consensus price target analysis for Klaviyo to understand how Wall Street targets line up with that story.

Klaviyo bear case focuses on quality of growth

The bearish argument on Klaviyo is that AI agents and new channels inflate usage while pressuring margins and delaying real monetization. This quarter gives that view some footing. Non GAAP gross margin slipped to 73.4% as mix shifted toward text and WhatsApp and as infrastructure spending increased. Management explicitly cut the full year profit outlook by about US$10m at the midpoint to fund Agency and heavier product work. That is a clear miss versus any expectation that AI could scale within the prior margin guide.

Bears also worry that expansion into larger customers and international markets stretches sales cycles and clouds earnings visibility. Net revenue retention at 109% still reflects a drag from last year’s profile enforcement, and management does not expect that to clear until Q1 2027. Combined with the CFO transition and a 13% share price drop on the day, execution risk remains front and center rather than disproved.
