Rhea-AI Filing Summary

Similarweb Ltd. reported a strong second quarter 2026, with revenue of $77.2 million, up 9% from $71.0 million a year earlier, and its first-ever positive GAAP operating profit of $0.7 million, or 1% of revenue. GAAP net loss narrowed to $3.6 million from $11.8 million, while non-GAAP operating profit rose to $6.5 million (8% margin) and non-GAAP net income to $5.2 million (7% margin), or $0.06 per diluted share.

Operationally, customers with ARR of $100,000 or more grew 9% to 473 and contributed 69% of total ARR. Overall dollar-based NRR was 100%, with 107% NRR for large customers. Remaining performance obligations increased 26% year-over-year to $345.3 million, and the company surpassed $300 million in ARR in June. Normalized free cash flow for the quarter was $8.7 million, with cash and cash equivalents of $73.9 million as of June 30, 2026.

On the back of strong AI-related demand and over $60 million in new multi-year contracts, Similarweb raised its outlook. For full-year 2026 it now guides to $314.0–$318.0 million in revenue (about 11.8% growth at the midpoint) and $24.0–$26.0 million in non-GAAP operating profit. For Q3 2026 it expects revenue of $80.5–$82.5 million (about 13.5% growth at the midpoint) and non-GAAP operating profit of $7.5–$9.5 million.

Positive

  • First-ever positive GAAP operating profit of $0.7 million (1% margin) marks a key profitability milestone while revenue continues to grow.
  • Raising full-year 2026 guidance to $314.0–$318.0 million revenue and $24.0–$26.0 million non-GAAP operating profit, implying about 11.8% revenue growth at the midpoint.
  • Remaining performance obligations up 26% year-over-year to $345.3 million, providing stronger visibility into future revenue.
  • Normalized free cash flow of $8.7 million in Q2 and $73.9 million in cash and cash equivalents support liquidity and ongoing investment capacity.

Negative

  • Despite improving results, the company still reported a GAAP net loss of $3.6 million in Q2 2026 and a six-month net loss of $9.9 million.

Filing Explained

The filing adds most of the results release to existing registration statements, while the June 30 balance sheet reports 88,248,704 outstanding shares.

This Form 6-K is an interim report that discloses the company’s incorporation of most of Exhibit 99.1 by reference into six Form S-8 registration statements and one Form F-3 registration statement.

The incorporation excludes the “Financial Outlook” section, so the listed registration documents are updated with the included results-release material but not its forward-looking outlook. The balance sheet reports 86,962,202 outstanding shares on December 31, 2025 and 88,248,704 on June 30, 2026. A larger outstanding share base would reduce an existing holder’s percentage ownership if that holder’s shares did not change, although this filing does not establish a holder-specific effect.

Q2 2026 GAAP Operating Profit $0.7 million Profit from operations in Q2 2026, 1% of revenue, first positive GAAP operating quarter

FY 2026 Revenue Guidance $314.0–$318.0 million Projected total revenue for fiscal year 2026, ~11.8% growth at midpoint
Q2 2026 Normalized Free Cash Flow $8.7 million Normalized free cash flow for the three months ended June 30, 2026
Annual recurring revenue (ARR) financial
"Similarweb surpassed $300 million in ARR in June."
Annual Recurring Revenue (ARR) is the predictable amount of money a company expects to earn in a year from its ongoing services or subscriptions. It helps businesses understand their steady income stream, much like knowing how much rent they can count on each year, which is important for planning and growth.
Net retention rate (NRR) financial
"Dollar-based net retention rate (NRR) for customers with ARR of $100,000 or more was 107%."
Net retention rate measures how much revenue a company keeps and grows from its existing customers over a set period, counting renewals, upgrades, downgrades and cancellations. Think of it like a garden: beyond keeping the original plants alive, it also counts new fruit from those plants—if the garden produces more fruit per plant, that’s healthy growth. Investors use it to judge how durable and self-sustaining revenue is without relying solely on new customers.
Remaining performance obligations financial
"Remaining performance obligations, or RPO, increased 26% year-over-year, to $345.3 million."
Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.
normalized free cash flow financial
"Normalized free cash flow was $8.7 million, compared to $3.8 million."
Normalized free cash flow is a company’s cash left over from operations after necessary spending, adjusted to remove one-time or unusual items so it reflects the cash the business typically generates. For investors it matters because it shows the sustainable, repeatable amount available for dividends, debt repayment, or reinvestment—like averaging out a household’s income by excluding a one-off bonus to see its regular budget.
non-GAAP operating profit financial
"Non-GAAP operating profit was $6.5 million or 8% of revenue."
Non-GAAP operating profit is a company’s operating earnings after removing or adjusting items that management considers unusual, one-time, or not part of regular operations (for example, restructuring costs or stock-based pay). Investors use it like a cleaned-up scorecard to see the company’s core business performance without temporary noise, but because the adjustments aren’t standardized, it’s best compared across peers with caution.
Q2 2026 Revenue $77.2 million Increased from $71.0 million in Q2 2025
Q2 2026 GAAP Operating Profit $0.7 million Improved from a $6.9 million GAAP operating loss in Q2 2025
Q2 2026 Non-GAAP Operating Profit $6.5 million Up from $2.4 million in Q2 2025
Q2 2026 Non-GAAP Net Income $5.2 million Up from $1.1 million in Q2 2025
RPO $345.3 million Increased 26% year-over-year from $273.8 million as of June 30, 2025
Guidance

For FY 2026, revenue is estimated at $314.0–$318.0 million with non-GAAP operating profit of $24.0–$26.0 million. For Q3 2026, revenue is estimated at $80.5–$82.5 million with non-GAAP operating profit of $7.5–$9.5 million.

Exhibit 99.1
The Company’s third 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 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.
The Company has introduced disclosure of both non-GAAP net income (loss) and non-GAAP net income (loss) per share beginning with the second quarter of 2025. A reconciliation of non-GAAP to GAAP financial measures is presented at the end of this press release.
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, August 12, 2026. A live webcast of the call can be accessed from Similarweb’s Investor Relations website at https://ir.similarweb.com. An archived webcast of the conference call will also be made available on the Similarweb website following the call. The live call may also be accessed via telephone at (877) 407-0726 toll-free and at +1 (201) 689-7806 internationally.

Exhibit 99.1

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, 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
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. 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.

6

Exhibit 99.1
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.
