Amplitude Q3 Revenue Rises 25% as ARR Reaches $431 Million

Amplitude Inc. (NASDAQ: AMPL) reported 25% year-over-year revenue growth for the third quarter ended September 30, 2026, while higher annual recurring revenue, large-customer growth and broader product adoption supported continued expansion. The digital analytics company also generated $5.7 million in non-GAAP operating income and issued fourth-quarter revenue guidance of $110.8 million to $113.2 million.

Third-quarter revenue reached $110.6 million, compared with $88.6 million a year earlier. Annual recurring revenue, an operating metric that is not equivalent to annualized GAAP revenue, increased 24% to $431 million. Net new ARR was $21 million, up from $12 million in the third quarter of 2025.

Non-GAAP operating income rose to $5.7 million from $0.6 million a year earlier, representing a 5% operating margin. Free cash flow increased to $5.8 million from $3.4 million, also producing a 5% margin. Amplitude reported a 70% non-GAAP gross margin and ended the quarter with $155 million in cash and investments.

Remaining performance obligations increased 27% year over year to $497 million. That total included $331 million of current RPO and $166 million of long-term RPO.

Large customers and multi-product use expand

Amplitude had 855 customers generating at least $100,000 in ARR, an increase of 31% from a year earlier. Enterprise customers—defined as businesses with more than 1,000 employees or over $100 million in revenue—accounted for 77% of ARR.

The company’s platform-consolidation strategy was reflected in wider use of multiple products. Half of its customers used more than one product, while customers with at least two products represented 81% of ARR. Customers using at least three products accounted for 62% of ARR, with the corresponding shares for four or more and five or more products reaching 45% and 29%, respectively.

Pro forma dollar-based net retention was 105%, compared with 104% in the prior-year quarter. The pro forma measure includes both Amplitude and Statsig customers; excluding ARR attributable to Statsig, net retention was 103%.

Amplitude said its growth strategy centers on accelerating net new ARR, consolidating customer workloads on its platform and balancing growth with operating leverage. Its identified growth drivers include product development, new-customer acquisition, multi-product adoption, additional use cases and industry coverage, international expansion, and its partner ecosystem.

Fourth-quarter and full-year outlook

For the fourth quarter of 2026, management expects revenue of $110.8 million to $113.2 million, representing year-over-year growth of 21% to 24%. Non-GAAP operating income is projected at $7 million to $9 million, with non-GAAP diluted net income per share of $0.05 to $0.06 based on approximately 142.5 million diluted shares.

For the full year, Amplitude expects revenue of $415.8 million to $418.2 million, equivalent to growth of 21% to 22%. The company forecast non-GAAP operating income of $8.9 million to $10.9 million and non-GAAP diluted net income per share of $0.07 to $0.09, based on about 139 million diluted shares.

Amplitude did not provide corresponding GAAP profit guidance or reconciliations, citing the difficulty of forecasting items including stock-based compensation and the amortization of acquired intangible assets without unreasonable effort.

The company cautioned that its outlook depends on assumptions that are inherently uncertain. It operates in what it described as a competitive, new and rapidly changing market, and actual results could differ materially because of known and unknown risks, including those detailed in its regulatory filings.
