Similarweb Ltd.

"The AI revolution fundamentally favors companies with proprietary, high-quality, and real-time data. Similarweb's unmatched view of the evolving digital world is a prime foundation for training and maintaining LLMs and powering the next generation of agentic AI tools with accuracy and trust, as validated by our recent milestone partnership with Manus," said Or Offer, Co-Founder and CEO of Similarweb. "While the scale of new larger, multi-year opportunities has resulted in longer sales cycles and revenue growth did not yet accelerate in the fourth quarter as we expected, the demand we see in the pipeline and the steps we have taken to upskill and specialize our sales force reinforce our confidence in our strategy to build an AI-driven data powerhouse that delivers profitable growth."

Financial Outlook

• FY 2026 Guidance
  
  
  
  
  • Total revenue for fiscal year 2026 estimated between $305.0 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 $16.0 million and $19.0 million.
    
    
    
    
• Q1 2026 Guidance
  
  
  
  
  • Total revenue estimated between $72.0 million and $74.0 million, representing approximately 9% growth year-over-year at the mid-point of the range.
    
    
    
    
  • Non-GAAP operating profit estimated between $0.5 million and $2.5 million.

The Company's first 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 profit (loss), and similarly cannot provide a reconciliation of this measure to its 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.

Conference Call Information

The financial results and business highlights will be discussed on a conference call and webcast scheduled at 8:30 a.m. Eastern Time on Wednesday, February 18, 2026. A live webcast of the call can be accessed from Similarweb's Investor Relations website at https://ir.similarweb.com.

These risks and uncertainties are more fully described in our filings with the Securities and Exchange Commission, including in the section entitled "Risk Factors" in our Form 20-F filed with the Securities and Exchange Commission on February 27, 2025, and subsequent reports that we file with the Securities and Exchange Commission. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, we cannot guarantee future results, levels of activity, performance, achievements, or events and circumstances reflected in the forward-looking statements will occur.

Forward-looking statements represent our beliefs and assumptions only as of the date of this press release. Except as required by law, we undertake no duty to update any forward-looking statements contained in this release as a result of new information, future events, changes in expectations or otherwise.

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. 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.
