The guidance provided above are forward-looking statements and actual results may differ materially. Refer to the “Forward-Looking Statements” safe harbor section below for information on the factors that could cause our actual results to differ materially from these forward-looking statements.

The section titled “Non-GAAP Financial Measures” below contains a description of the non-GAAP financial measures used in this press release, definitions of our operating metrics and a reconciliation of GAAP and non-GAAP financial measures is contained in the tables below. A reconciliation of non-GAAP measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort due to the uncertainty regarding, and the potential variability of, costs and expenses, including the impact of stock-based compensation, which is dependent on factors such as future stock price and volume of equity awards granted in the future, that may be incurred in the future and therefore, cannot be reasonably predicted. The effect of these excluded items may be significant.

CFO Transition

Anaplan also today announced that Chief Financial Officer David H. Morton, Jr. will step down from his position later this year to spend more time with his family. Anaplan has initiated a search for its next CFO with the assistance of an external search firm, and Dave will continue in his role until his successor is hired.

“On behalf of the Board and the leadership team, I thank Dave for his years of service to Anaplan and his many contributions to advance our finance organization. We wish him the best as we initiate the process to find Anaplan’s next CFO,” said Frank Calderoni, President and CEO of Anaplan.

“It has been a privilege to work alongside so many talented people at Anaplan, and now is the right time to begin this transition,” said Morton. “The need for scenario-based planning has never been greater and Anaplan is fully focused on executing against the opportunities ahead. I look forward to doing whatever I can to support Anaplan’s path forward, including assisting with the search process.”

Non-GAAP Financial Measures

In addition to financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables contain non-GAAP financial measures, including non-GAAP loss from operations, non-GAAP operating margin, non-GAAP net loss, non-GAAP net loss per share, and free cash flow. The non-GAAP financial information is presented for supplemental informational purposes only, and is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. The non-GAAP measures presented here may be different from similarly-titled non-GAAP measures used by other companies.

We use these non-GAAP measures in conjunction with GAAP measures as part of our overall assessment of our performance, including the preparation of our annual operating budget and quarterly forecasts, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance. We believe these non-GAAP measures, when viewed collectively with the GAAP measures, may be helpful to investors because they provide consistency and comparability with our past financial performance and facilitate period-to-period comparisons of our operating results.

There are material limitations associated with the use of non-GAAP financial measures since they exclude significant expenses and income that are required by GAAP to be recorded in our financial statements. The definitions of our non-GAAP measures may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may utilize metrics

8

that are not similar to ours. We compensate for these limitations by analyzing current and future results on a GAAP basis as well as a non-GAAP basis and by providing specific information regarding the GAAP items excluded from these non-GAAP financial measures. Please see the reconciliation tables in this release for the reconciliation of GAAP and non-GAAP results.

We adjust the following items from one or more of our non-GAAP financial measures:

Stock-based compensation expense. We exclude stock-based compensation expense, which is a non-cash expense, from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. In particular, companies calculate stock-based compensation expense using a variety of valuation methodologies and subjective assumptions.

Employer payroll tax expense related to employee stock plans. We exclude employer payroll tax expense related to employee stock plans, which is a cash expense, from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. In particular, this expense is tied to the exercise or vesting of underlying equity awards and the price of our common stock at the time of exercise or vesting, which may vary from period to period independent of the operating performance of our business.

Amortization of acquired intangible assets. We exclude amortization of acquired intangible assets, which is a non-cash expense, from certain of our non-GAAP financial measures. Our expenses for amortization of intangible assets are inconsistent in amount and frequency because they are significantly affected by the timing, size of acquisitions and the inherent subjective nature of purchase price allocations. We exclude these amortization expenses because we do not believe these expenses have a direct correlation to the operation of our business.

Business combinations and related cost. We exclude transaction, integration, and retention expenses that are directly related to business combinations from certain of our non-GAAP financial measures because we believe that excluding these items provides meaningful supplemental information regarding operational performance.

Free cash flow. Our management reviews cash flows generated from operations after taking into consideration capital expenditures such as purchase of property and equipment and internal-use software as these expenditures are considered to be a necessary component of ongoing operations. We define non-GAAP free cash flow as net cash provided by (used in) operating activities, reduced by purchase of property and equipment and capitalization of internal-use software.

Operating Metrics

Annual recurring revenue (ARR) is calculated as subscription revenue already booked and in backlog that will be recorded over the next 12 months, assuming any contract expiring in those 12 months is renewed and continues on its existing terms and at its prevailing rate of utilization.

Dollar-based Net Expansion Rate is calculated as the ARR at the end of a period for the base set of customers from which we had ARR in the year prior to the calculation, divided by the ARR one year prior to the date of calculation for that same customer base.
