Datto Holding Corp. (Datto) (NYSE: MSP), the leading global provider of cloud-based software and security solutions purpose-built for delivery by managed service providers (MSPs), today announced its financial results for the second quarter ended June 30, 2021.

“Our second quarter results mark one of the strongest quarters in our history and are a clear indication of the power of the MSP model,” said Tim Weller, Datto’s Chief Executive Officer. “Our subscription revenue growth accelerated to 21% year-over-year and we added 500 net new partners in the quarter, both representing new highs since the onset of the pandemic in early 2020. Looking ahead, we continue to see strong momentum across our business and are excited about the new product launches in cloud and security planned for the second half of 2021. We remain well positioned to capitalize on the large opportunity to help our MSP partners manage, protect, and connect their SMB clients’ data in an increasingly digital world.”

Forward-Looking Statements

This press release contains forward-looking statements that reflect Datto’s current expectations and projections with respect to, among other things, its financial condition, results of operations, plans, objectives, future performance, and business. These statements may be preceded by, followed by or include the words ‘‘anticipate,’’ ‘‘estimate,’’ ‘‘expect,’’ ‘‘project,’’ ‘‘plan,’’ ‘‘intend,’’ ‘‘believe,’’ ‘‘may,’’ ‘‘will,’’ ‘‘should,’’ ‘‘can have,’’ ‘‘likely’’ and the negatives thereof and other words and terms of similar meaning. Further information on potential factors that could affect our results is included in our Annual Report on Form 10-K.

Forward-looking statements include all statements that are not historical facts. Such forward-looking statements are subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements.

There is no assurance that any forward-looking statements will materialize. You are cautioned not to place undue reliance on forward-looking statements, which reflect expectations only as of this date. Datto undertakes no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), we believe that the non-GAAP financial measures of Non-GAAP Subscription Cost of Revenue, Non-GAAP Device Cost of Revenue, Non-GAAP Professional Services and Other Cost of Revenue, Non-GAAP Depreciation and Amortization in Cost of Revenue, Non-GAAP Cost of Revenue, Non-GAAP Gross Profit, Non-GAAP Sales and Marketing expense, Non-GAAP Research and Development expense, Non-GAAP General and Administrative expense, Non-GAAP Depreciation and Amortization in Operating Expenses, Non-GAAP Operating Expenses, Non-GAAP Income from Operations, Non-GAAP Net Income and Non-GAAP Net Income Per Share, Adjusted EBITDA, and Free Cash Flow are useful in evaluating our operating performance. Certain of these measures exclude interest and other (income) expense, net, loss on extinguishment of debt, depreciation and amortization, stock-based compensation expense, restructuring expense and transaction related and other expense. In addition, for Non-GAAP Net Income we utilize a non-GAAP tax rate of 25%, which we believe reflects our normalized effective tax rate. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, and should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly-titled non-GAAP measures used by other companies.

Reconciliation tables of the most directly comparable GAAP financial measures to the non-GAAP financial measures used in this press release are included with the financial tables at the end of this press release.

Datto is not providing a quantitative reconciliation of forward-looking guidance of Adjusted EBITDA to its most directly comparable GAAP measure because certain items are out of Datto’s control or cannot be reasonably predicted, as the items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. Accordingly, a reconciliation for forward-looking Adjusted EBITDA is not available without unreasonable effort.
