Key Financial Metrics

Key Operating Metrics:
- Annual Recurring Revenue (ARR): $366 million (up 17% YoY).
- Dollar-Based Net Retention Rate (TTM): 104% (up from 97%).

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 15% driven by customer base expansion and upselling, partially offset by churn. Subscription revenue comprised 98% of total revenue.
• Cost of Revenue: Increased 16% primarily due to higher third-party hosting costs ($6.0M increase) and amortization of capitalized software ($3.4M increase).
• Operating Expenses:
  • R&D: Flat at $97.6 million. The increase in personnel costs was offset by a decrease in stock-based compensation (SBC) due to the absence of a one-time acquisition-related acceleration in 2025 that occurred in 2024.
  • Sales & Marketing: Increased 12% to $188.0 million, driven by higher personnel expenses and SBC.
  • G&A: Increased 1% to $64.3 million.
• Liquidity: Cash and cash equivalents decreased significantly from $171.7 million to $81.1 million, largely due to share repurchases ($30.8 million) and tax withholdings on equity awards ($38.4 million), partially offset by positive operating cash flow.

Guidance, Outlook, and Risks

Management Commentary & Outlook:
- Management expects to continue investing in R&D, sales, and international expansion. While operating expenses are expected to increase in absolute dollars, they anticipate these expenses as a percentage of revenue will decrease over the long term.
- The company launched several AI-focused products in 2025, including AI Agents, Amplitude MCP, AI Visibility, AI Feedback, and Automated Insights, aiming to drive further platform adoption.
- No specific forward-looking financial guidance (e.g., revenue ranges) was provided in the text.

Risks and Contingencies:
- Profitability: The company has a history of losses and an accumulated deficit of $546.4 million. There is no guarantee it will achieve or sustain profitability.
- AI Regulation: Evolving regulations regarding AI (e.g., EU AI Act, US executive orders) could increase compliance costs or limit product capabilities.
- Competition: The market is highly competitive with point-solution providers and large integrated vendors.
- Legal Proceedings: The company is defending against privacy class actions (e.g., Atkins v. Amplitude) and previously defended securities class actions. Outcomes are uncertain.
- Concentration: No single customer accounted for more than 10% of revenue.

Investor Verification Checklist

• Path to Profitability: Verify the timeline and specific cost-reduction strategies required to convert the GAAP operating loss into income, given the continued investment in growth.
• Stock-Based Compensation (SBC): Review the impact of SBC on future earnings, noting the $92.1 million expense in 2025 and the $136.5 million of unrecognized SBC expense related to RSUs.
• Share Repurchase Program: Confirm the remaining authorization ($26.1 million as of year-end, increased to $123.1 million in February 2026) and the impact on cash reserves.
• Customer Concentration: Validate the stability of the top 56 customers representing >$1M ARR, as they drive a significant portion of revenue growth.
• Legal Exposure: Monitor the status of pending privacy class actions and potential arbitration outcomes.
• AI Product Adoption: Assess the revenue contribution of new AI products launched in 2025 to ensure they are driving the projected expansion.
