Financial Outlook
"Revenue growth continued to accelerate this quarter, driven by new customer acquisition and improving retention,” stated Jason Schwartz, Chief Financial Officer of Similarweb. “Our operational performance this quarter highlights our commitment to disciplined execution." He further noted, “We achieved a fourth consecutive quarter of operating profit and generated $16 million in free cash flow in the first half of 2024. Given these results, which exceeded our expectations, we are raising our revenue and non-GAAP operating profit outlook for the full year 2024." Schwartz emphasized the company's progress, saying, “We are making significant strides towards our long-term profit and free cash flow targets.”
Q3 2024 Guidance
Total revenue estimated between $62.5 million and $63.0 million, representing approximately 15% growth year over year at the mid-point of the range.
Non-GAAP operating profit estimated between $2.8 million and $3.2 million.
FY 2024 Guidance
Total revenue estimated between $246.0 million and $248.0 million.
Non-GAAP operating profit estimated between $13.0 million and $15.0 million.
The Company’s third quarter and full year 2024 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 and gross margin, the most directly comparable GAAP measures to non-GAAP operating loss and non-GAAP gross margin, respectively, and similarly cannot provide a reconciliation of these measures to their closest GAAP equivalents 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.

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.

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

Exhibit 99.1
as a substitute for, financial information prepared in accordance with GAAP. 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 and non-GAAP general and administrative expenses 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, 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.
