Recent Business Highlights

• The company recently expanded its ecommerce offering with the launch of Similarweb Retail Intelligence, a unified suite that combines Amazon IQ with Cross-Retail IQ to give brands and retailers a more complete view of shopper behavior and digital shelf performance. The product extends Similarweb’s coverage across Amazon marketplaces and more than 650 online stores and marketplaces, enabling customers to analyze product mix, availability, pricing, competitive positioning, and emerging retail trends in a single intelligence layer.
• In May, Similarweb expanded its partnership with Manus, embedding additional keyword, referral, landing page and popular page datasets into Manus’s AI agent experience. Building on the January integration of Similarweb traffic and engagement data, Manus users can now ask plain-language business questions and generate competitive intelligence briefs that explain not only who is winning online, but why. The expansion strengthens Similarweb’s role as an AI-native intelligence layer, grounding agent-driven workflows in trusted, real-world digital data.
• During the first quarter, the company signed a seven digit LLM data training contract with an existing big tech customer. This was one of the two contracts that was deferred from the fourth quarter. We expect a second large LLM data contract to be signed over the coming quarters.

"This was our tenth consecutive quarter of positive normalized free cash flow, reinforcing our commitment to disciplined execution, profitable growth and durable cash generation. Our first quarter performance provides a solid base for 2026, and we are raising the low end of our full year guidance to reflect increased confidence in our outlook."

Financial Outlook

• FY 2026 Guidance
  • Total revenue for fiscal year 2026 estimated between $307.0 million and $315.0 million, representing approximately 10% growth year-over-year at the mid-point of the range.
  • Non-GAAP operating profit for fiscal year 2026 estimated between $17.0 million and $19.0 million.
• Q2 2026 Guidance
  • Total revenue estimated between $74.5 million and $76.5 million, representing approximately 6% growth year-over-year at the mid-point of the range.
  • Non-GAAP operating profit estimated between $3.0 million and $5.0 million.

The Company’s second quarter and full year 2026 financial outlook is based upon a number of assumptions that are subject to change and many of which are outside the Company’s control. Actual results may vary from these assumptions, and the Company’s expectations may change. There can be no assurance that the Company will achieve these results.

The Company does not provide guidance for operating loss, the most directly comparable GAAP measure to non-GAAP operating loss, and similarly cannot provide a reconciliation of this measure to their closest GAAP equivalent without unreasonable effort due to the unavailability of reliable estimates for certain items. These items are not within the Company’s control and may vary greatly between periods and could significantly impact future financial results.

Non-GAAP Financial Measures

This press release contains certain financial measures that are expressed on a non-GAAP basis. We use these non-GAAP financial measures internally to facilitate analysis of our financial and business trends and for internal planning and forecasting purposes. We believe these non-GAAP financial measures, when taken collectively, may be helpful to investors because they provide consistency and comparability with past financial performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. However, non-GAAP financial measures have limitations as an analytical tool and are presented for supplemental informational purposes only. They should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP or as a measure of liquidity. Free cash flow represents net cash provided by (used in) operating activities less capital expenditures and capitalized internal-use software costs. Normalized free cash flow represents free cash flow less capital investments related to the Company's new headquarters, payments received in connection with these capital investments and deferred payments related to business combinations. Non-GAAP operating income (loss), non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating margin, non-GAAP research and development expenses, non-GAAP sales and marketing expenses, non-GAAP general and administrative expenses, non-GAAP net income (loss) and non-GAAP net income (loss) per share represent the comparable GAAP financial figure operating income (loss) or expense, less share-based compensation, adjustments and payments related to business combinations, amortization of intangible assets and certain other non-recurring items, non-operating foreign exchange gains or losses and the relevant net tax effect as applicable and indicated in the below tables.

Other Metrics

Customer acquisition costs (CAC) represent the portion of sales and marketing expenses allocated to acquire new customers. Customer retention costs (CRC) represent the portion of sales and marketing expenses allocated to retain existing customers and to increase existing customers’ subscriptions. Annual recurring revenue (ARR) represents the annualized subscription revenue we would contractually expect to receive from customers assuming no increases or reductions in their subscriptions. CAC payback period is the estimated time in months to recover CAC in terms of incremental gross profit that newly acquired customers generate. Net retention rate (NRR) represents the comparison of our ARR from the same set of customers as of a certain point in time, relative to the same point in time in the previous year ago period, expressed as a percentage.

We define Annual Recurring Revenue (ARR) as the annualized subscription revenue we would contractually expect to receive from customers assuming no increases or reductions in their subscriptions. A contract is included in ARR for a particular period if it is active at the end of the applicable period and is excluded if it is not active at the end of the applicable period. Multi-year contracts are annualized by dividing the total committed contract value by the number of months in the subscription term and then multiplying by 12. ARR excludes non-recurring revenues, non-subscription revenues, revenues that are one-time in nature or revenues from subscriptions to our offerings for a period that is less than an annual subscription term.

ARR is an operational measure that management uses to evaluate the scale of our annual subscription contracts. While ARR is useful in assessing the scale of our contracted subscription business, it is not necessarily indicative of future GAAP revenue, which is subject to factors such as customer renewals, expansions, contractions, churn and upsell or cross-sell opportunities. Since ARR is not a defined measure under GAAP, investors should not consider ARR as a substitute for revenue recognized under GAAP or for other GAAP-related measures such as remaining performance obligations or deferred revenue. ARR differs from revenue recognized in accordance with GAAP because GAAP revenue is recognized as performance obligations are satisfied, includes non-recurring revenues, such as revenue that is one-time in nature, subscriptions with less than an annual term, non-subscription revenue and the effects of contract modifications.
