Non-GAAP Financial Measures

In this release, HubSpot’s non-GAAP operating loss, operating margin, subscription margin, expense, expense as a percentage of revenue, net loss, and free cash flow are not presented in accordance with GAAP and are not intended to be used in lieu of GAAP presentations of results of operations.

Management presents these non-GAAP financial measures because it considers them to be important supplemental measures of performance. Management uses the non-GAAP financial measures for planning purposes, including analysis of the company’s performance against prior periods, the preparation of operating budgets and to determine appropriate levels of operating and capital investments. Management also believes that the non-GAAP financial measures provide additional insight for analysts and investors in evaluating the company’s financial and operational performance. However, these non-GAAP financial measures have limitations as an analytical tool and are not intended to be an alternative to financial measures prepared in accordance with GAAP. We intend to provide these non-GAAP financial measures as part of our future earnings discussions and, therefore, the inclusion of these non-GAAP financial measures will provide consistency in our financial reporting. Investors are encouraged to review the reconciliation of these 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 above in this press release.

These non-GAAP measures exclude share-based compensation and amortization of acquired intangible assets. We believe investors may want to exclude the effects of these items in order to compare our financial performance with that of other companies and between time periods:

Page | 9

(a) Stock-based compensation is a non-cash expense accounted for in accordance with FASB ASC Topic 718. We believe that the exclusion of stock-based compensation expense allows for financial results that are more indicative of our operational performance and provide for a useful comparison of our operating results to prior periods and to our peer companies because stock-based compensation expense varies from period to period and company to company due to such things as differing valuation methodologies and changes in stock price.

(b) Expense for the amortization of acquired intangible assets is a non-cash item, and we believe that the exclusion of this amortization expense provides for a useful comparison of our operating results to prior periods and to our peer companies.
