See “Non-GAAP Financial Measures & Definitions of Key Metrics” below for how Semrush defines ARR, dollar-based net revenue retention, non-GAAP net income (loss), and the financial tables that accompany this release for reconciliations of each non-GAAP financial measure to its closest comparable GAAP financial measure.

Third Quarter 2023 Business Highlights

We are committed to empowering our customers with the best-in-class platform needed to boost their online presence and gain an edge in the market. In the third quarter, we advanced and expanded many of our offerings:

•Continued investments in Generative AI to provide enhanced, more efficient content creation capabilities through Semrush’s platform and App Center:

◦Released two new ChatGPT features in the Listing Management tool that allows customers to reply to online reviews faster and find higher-quality keywords for their local business listings.

◦Introduced the AI Social Media Post Generator, an AI-powered tool that generates social media posts based on trending topics, enabling customers to amplify their social presence while speeding up the content creation process.

◦Launched the Ecommerce Booster app that uses built-in AI tools to audit product page performance and create customized action plans, helping businesses easily improve their Shopify listings.

•Semrush customers who pay more than $10,000 annually grew by more than 20% year-over-year.

•Ended the quarter with more than 987,000 registered free active customers, up 25% year-over-year.

As of September 30, 2023, we had approximately 106,800 paying customers, accounting for $322.8 million in ARR, an increase from 94,000 paying customers accounting for $267.3 million in ARR as of September 30, 2022.

Business Outlook

“Looking at the fourth quarter, I am confident in the underlying trends in the business and capabilities of our team as we continue on the path to delivering strong growth and profitability. As a result, we are meaningfully raising our non-GAAP net income guidance to account for our improved efficiency and tightening our previously issued top line guidance,” said Brian Mulroy, CFO of Semrush. “We believe we will continue to make progress on our revenue growth pillars and maintain a disciplined and balanced approach to improving efficiency and profitability while also investing in future growth opportunities that we expect will drive long-term value.”

Based on information as of today, November 1, 2023, we are issuing the following financial guidance:

Fourth Quarter 2023 Financial Outlook

•For the fourth quarter, we expect revenue in a range of $82.7 to $83.7 million, which at the mid-point would represent growth of approximately 21% year-over-year.

•We expect fourth quarter non-GAAP net income of $4.1 to $6.1 million.

Full-Year 2023 Financial Outlook

•For the full year, we are tightening our revenue guidance to $307.0 to $308.0 million, which would represent growth at the midpoint of approximately 21% year-over-year.

•We are raising our non-GAAP net income guidance to $9.0 to $11.0 million, up from our prior guidance of $2.0 to $4.0 million, for the full year 2023.

Reconciliation of non-GAAP net income guidance to the most directly comparable GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from this non-GAAP measure, in particular the measures and effects of share-based compensation expense, employer taxes and tax deductions specific to equity compensation awards that are directly impacted by future hiring, turnover and retention needs. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.

Non-GAAP Financial Measures & Definitions of Key Metrics

Semrush has provided in this release the non-GAAP financial measures of non-GAAP income (loss) from operations and non-GAAP net income (loss). Semrush uses these non-GAAP financial measures internally in analyzing its financial results and believes it is useful to investors, as a supplement to GAAP measures, in evaluating Semrush’s ongoing operational performance. Semrush believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing its financial results with other companies in Semrush’s industry, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures have limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of non-GAAP measures to their most directly comparable GAAP financial measures. A reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.

ARR is defined as of a given date as the monthly recurring revenue that we expect to contractually receive from all paid subscription agreements that are actively generating revenue as of that date multiplied by 12. We include both monthly recurring paid subscriptions, which renew automatically unless canceled, as well as the annual recurring paid subscriptions so long as we do not have any indication that a customer has canceled or intends to cancel its subscription and we continue to generate revenue from them.

Dollar-based net revenue retention is defined as (a) the revenue from our customers during the twelve-month period ending one year prior to such period as the denominator and (b) the revenue from those same customers during the twelve months ending as of the end of such period as the numerator. This calculation excludes revenue from new customers and any non-recurring revenue.

Non-GAAP income (loss) from operations. We define non-GAAP income (loss) from operations as GAAP income (loss) from operations, excluding stock-based compensation expense. We believe non-GAAP income (loss) from operations provides our management and investors consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as it eliminates the effect of stock-based compensation, which is often unrelated to overall operating performance.

Non-GAAP net income (loss). We define non-GAAP net income (loss) as GAAP net income (loss), excluding stock-based compensation expense. We believe non-GAAP net income (loss) provides our management and investors consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as it eliminates the effect of stock-based compensation, which is often unrelated to overall operating performance.
