Fourth Quarter and 2021 Financial Outlook
For the fourth quarter of 2021, the Company currently expects:
•Total revenue between $51.2 and $51.3 million, or overall growth of 37%.
•Non-GAAP operating loss between ($4.0) million and ($3.5) million.
•Non-GAAP net loss per share of between ($0.07) and ($0.06) based on approximately 54.1 million weighted-average shares of common stock outstanding.
“We are pleased to deliver positive free cash flow and another very efficient quarter,” said Joe Del Preto, CFO. “We’re continuing to drive fast growth with improving efficiency, which underscores the attractiveness of our unit economics. As we shared recently at investor day, these economics reinforce our confidence in durable, multi-year growth.”
For the full year 2021, the Company is updating guidance to reflect the following:
•Total revenue between $185.8 to $185.9 million, or overall growth of 40%.
•Non-GAAP operating loss between ($7.8) and ($7.3) million.
•At the midpoint of these ranges, this implies a (4.1%) operating margin and nearly 1,200bps of year-over-year operating margin improvement.
•Non-GAAP net loss per share of between ($0.15) and ($0.14) based on approximately 53.8 million weighted-average shares of common stock outstanding.
The Company’s fourth quarter and 2021 financial outlook is based on a number of assumptions that are subject to change and many of which are outside the Company’s control, including the impact of the ongoing COVID-19 pandemic on our financial performance and customer demand. If actual results vary from these assumptions, 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, or net loss per share, the most directly comparable GAAP measure to non-GAAP net loss per share, and similarly cannot provide a reconciliation between its forecasted non-GAAP operating loss and non-GAAP net loss per share and these comparable GAAP measures 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 financial results and business highlights will be discussed on a conference call and webcast scheduled at 4:00 p.m. Central Time (5:00 p.m. Eastern Time) today, November 2, 2021. Online registration for this event conference call can be

Forward-Looking Statements
This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “outlook,” “long-term model,” “may,” “might,” “plan,” “project,” “will,” “would,” “should,” “could,” “can,” “predict,” “potential,” “strategy, “target,” “explore,” “continue,” or the negative of these terms, and similar expressions intended to identify forward-looking statements. However, not all forward-looking statements contain these identifying words. These statements may relate to the impact on our business and the businesses of our prospective and existing customers of the COVID-19 pandemic, our market size and growth strategy, our estimated and projected costs, margins, revenue, expenditures and customer and financial growth rates, our Q4 and 2021 financial outlook, our plans and objectives for future operations, growth, initiatives or strategies. By their nature, these statements are subject to numerous uncertainties and risks, including factors beyond our control, that could cause actual results, performance or achievement to differ materially and adversely from those anticipated or implied in the forward-looking statements. These assumptions, uncertainties and risks include that, among others: the effects of the COVID-19 pandemic and the governmental actions taken to combat the pandemic may materially affect how we and our customers operate our businesses, and the duration and extent to which this threatens our future results of operations and overall financial performance remains uncertain; any decline in new customers, renewals or upgrades; our limited operating history makes it difficult to evaluate our prospects and future results of operations; we operate in competitive markets; we may not be able to sustain our revenue growth rate in the future; our business would be harmed by any significant interruptions, delays or outages in services from our platform or certain social media platforms; changing regulations relating to privacy, information security and data protection could increase our costs, affect or limit how we collect and use personal information and harm our brand; and a cybersecurity-related attack, significant data breach or disruption of the information technology systems or networks could negatively affect our business. Additional risks and uncertainties that could cause actual outcomes and results to differ materially from those contemplated by the forward-looking statements are included under the caption “Risk Factors” and elsewhere in our filings with the Securities and Exchange Commission (the “SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 24, 2021, as well as any other future quarterly and current reports that we file with the SEC. Moreover, you should interpret many of the risks identified in those reports as being heightened as a result of the ongoing and numerous adverse impacts of the COVID-19 pandemic. Forward-looking statements speak only as of the date the statements are made and are based on information available to Sprout Social at the time those statements are made and/or management's good faith belief as of that time with respect to future events. Sprout Social assumes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made, except as required by law.
Use of Non-GAAP Financial Measures
We have provided in this press release certain financial information that has not been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Our management uses these non-GAAP financial measures internally in analyzing our financial results and believes that use of these non-GAAP financial measures is useful to investors as an additional tool to evaluate ongoing operating results and trends and in comparing our financial results with other companies in our industry, many of which present similar non-GAAP financial measures. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable financial measures prepared in accordance with GAAP and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. A reconciliation of our historical non-GAAP financial measures to the most directly comparable GAAP measures has been provided in the financial statement tables included in this press release, and investors are encouraged to review these reconciliations.

Non-GAAP gross profit. We define non-GAAP gross profit as GAAP gross profit, excluding stock-based compensation expense. We believe non-GAAP gross profit 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 operating loss. We define non-GAAP operating loss as GAAP loss from operations, excluding stock-based compensation expense. We believe non-GAAP operating 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.
Non-GAAP net loss. We define non-GAAP net loss as GAAP net loss and comprehensive loss, excluding stock-based compensation expense. We believe non-GAAP net loss provides our management and investors consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as this non-GAAP financial measure eliminates the effect of stock-based compensation, which is often unrelated to overall operating performance.
Non-GAAP net loss per share. We define non-GAAP net loss per share as GAAP net loss per share attributable to common shareholders, basic and diluted, excluding stock-based compensation expense. We believe non-GAAP net loss per share provides our management and investors consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as this non-GAAP financial measure eliminates the effect of stock-based compensation, which is often unrelated to overall operating performance.
Free cash flow. We define free cash flow as net cash provided by (used in) operating activities less purchases of property and equipment. Free cash flow does not reflect our future contractual obligations or represent the total increase or decrease in our cash balance for a given period. We believe free cash flow is a useful indicator of liquidity that provides information to management and investors about the amount of cash used in our core operations that, after purchases of property and equipment, is not available for strategic initiatives.
Free cash flow margin. We define free cash flow margin as free cash flow as a percentage of revenue.
Customer Metrics
Annual recurring revenue (“ARR”). We define ARR as the annualized revenue run-rate of subscription agreements from all customers as of the last date of the specified period. We believe ARR is an indicator of the scale of our entire platform while mitigating fluctuations due to seasonality and contract term.
Number of customers. We define a customer as a unique account, multiple accounts containing a common non-personal email domain or multiple accounts governed by a single agreement. Number of customers excludes customers exclusively using legacy products obtained through the acquisition of Simply Measured. We believe that the number of customers using our platform is an indicator not only of our market penetration, but also of our potential for future growth as our customers often expand their adoption of our platform over time based on an increased awareness of the value of our platform and products.
Number of customers contributing more than $10,000 in ARR. We define number of customers contributing more than $10,000 in ARR as those on a paid subscription plan that had more than $10,000 in ARR as of a period end. We view the number of customers that contribute more than $10,000 in ARR as a measure of our ability to scale with our customers and attract larger organizations. We believe this represents potential for future growth, including expanding within our current customer base.
Number of customers contributing more than $50,000 in ARR. We define number of customers contributing more than $50,000 in ARR as those on a paid subscription plan that had more than $50,000 in ARR as of a period end. We view the number of customers that contribute more than $50,000 in ARR as a measure of our ability to scale with our largest customers and attract more sophisticated organizations. We believe this represents potential for future growth, including expanding within our current customer base. Over time, our largest customers have constituted a greater share of our revenue.
