The Basics
U.S. software company · mid-cap · listed on the NYSE · headquartered in Boston, Massachusetts.

• Operating income turned positive at $2M in Q1 2026, up from -$24M in Q1 2025, marking the first operating profit in the dataset.

• Revenue grew consistently from $222M in Q2 2024 to $358M in Q1 2026, with no quarter showing sequential decline.

• Equity expanded steadily from $980M in Q2 2024 to $1,197M in Q4 2025, though it dipped to $1,153M in Q1 2026.

⚠ Operating cash flow dropped sharply to $14M in Q1 2025 and $34M in Q1 2026, versus $60M and $93M in prior Q4s — seasonal pattern warrants monitoring.

⚠ Equity declined $44M sequentially in Q1 2026 — first quarterly drop in the dataset; underlying driver needs clarification.

⚠ No debt reported across all periods; absence of leverage data limits full balance-sheet assessment.

AI Insight: KVYO Ratio Trends

Klaviyo swung to profitability in Q1 2026, with operating margin turning positive at 0.5% after nine consecutive loss-making quarters.

• Operating margin improved from -0.5% in Q4 2025 to 0.5% in Q1 2026; net profit margin surged from 2.0% to 2.5% in same period.

• ROIC turned positive at 0.6% in Q1 2026, up sharply from -0.6% in Q4 2025, ending three-quarter streak of negative returns.

⚠ Profitability remains nascent; operating margin at 0.5% offers minimal buffer. Reversion to losses would signal execution weakness.

⚠ TTM operating margin at -3.2% lags latest quarter, suggesting profitability gains concentrated in Q1 2026 alone; seasonality risk.
