SAN FRANCISCO, CA, November 28, 2018 — Anaplan Inc. (NYSE:PLAN), a pioneer in Connected Planning, today announced financial results for its fiscal third quarter ended October 31, 2018.

Third Quarter Fiscal 2019 Financial Results

Financial Outlook

The Company is providing the following guidance for its fiscal fourth quarter 2019 and its full fiscal year 2019.

The section titled “Non-GAAP Financial Measures” below contains a description of the non-GAAP financial measures, 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, the costs and expenses that may be incurred in the future and therefore, cannot be reasonably predicted. The effect of these excluded items may be significant.

These statements identify prospective information and may include words such as “expects,” “intends,” “continue,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “potential,” “should,” “may,” “will,” or the negative version of these words, variations of these words and comparable terminology. These forward-looking statements are based on information available to the Company as of the date of this press release and are based on management’s current views and assumptions. These forward-looking statements are conditioned upon and also involve a number of known and unknown risks, uncertainties, and other factors that could cause actual results, performance

or events to differ materially from those anticipated by these forward-looking statements. Such risks, uncertainties, and other factors may be beyond the Company’s control and may pose a risk to the Company’s operating and financial condition. Such risks and uncertainties include, but are not limited to: we have a limited history of operating at our current scale and under our current strategy, which makes it difficult to predict our future operating results, and we may not achieve our expected operating results in the future; due to our history of net losses, we anticipate increasing our operating expenses in the future, and we do not expect to be profitable for the foreseeable future; our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business; because we derive substantially all of our revenue from a single software platform, failure of our Connected Planning solutions in general and our platform in particular to satisfy customer demands or to achieve increased market acceptance would adversely affect our business, results of operations, financial condition, and growth prospects; if we are unable to attract new customers, both domestically and internationally, the growth of our revenue will be adversely affected and our business may be harmed; our business depends substantially on our customers renewing their subscriptions and expanding their use of our platform and failure to achieve renewals and expansions may result in a material adverse effect on our business operations; the markets in which we participate are intensely competitive, and if we do not compete effectively, our business and operating results could be adversely affected; if we experience a security incident, our platform may be perceived as not being secure, our reputation may be harmed, customers may reduce the use of or stop using our platform, we may incur significant liabilities, and our business could be materially adversely affected; real or perceived errors, failures, bugs, service outages, or disruptions in our platform could adversely affect our reputation and harm our business; we have experienced rapid growth in recent periods and expect to continue to invest in our growth for the foreseeable future; if we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service, or adequately address competitive challenges; we could incur substantial costs in protecting or defending our intellectual property rights, and any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand; our global operations and sales to customers outside the United States or with international operations subject us to risks inherent in international operations that can harm our business, results of operations, and financial condition; the lack of a prior public market for our common stock; and the uncertainty in and volatility of the broader stock market generally or the stock price of our common stock specifically may result in shareholders not being able to resell their shares at or above the price at which they purchased shares. Information concerning risks, uncertainties and other factors that could cause results to differ materially from the expectations described in this press release is contained in the Company’s prospectus dated October 11, 2018 filed with the U.S. Securities and Exchange Commission pursuant to Rule 424(b)(4) under the Securities Act, the “Risk Factors” section, and other documents filed with or furnished to the Securities and Exchange Commission. These forward-looking statements should not be relied upon as representing the Company’s views as of any subsequent date and the Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made.

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 sales and marketing expense, non-GAAP research and development expense, non-GAAP general and administrative expense, 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 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 at the end of 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.

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.

Internal-use software. We include capitalization and the subsequent amortization of internal-use software, which is a non-cash expense, in certain of our non-GAAP financial measures. We capitalize certain costs incurred for the development of computer software for internal use and then amortize those costs over the estimated useful life. Capitalization and amortization of software development costs can vary significantly depending on the timing of products reaching technological feasibility and being made generally available. Moreover, because of the variety of approaches taken and the subjective assumptions made by other companies in this area, we believe that including the effects of capitalized software costs allows investors to make more meaningful comparisons between our operating results and those of other companies.

Purchase of property and equipment. We include purchase of property and equipment in certain of our non-GAAP financial measures, such as free cash flow. Our management reviews cash flows generated from operations after taking into consideration capital expenditures such as purchase of property and equipment as these expenditures are considered to be a necessary component of ongoing operations.

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.

Calculated Billings is defined as revenue plus the change in deferred revenue.
