Anaplan Announces First Quarter

Fiscal Year 2021 Financial Results

SAN FRANCISCO, May 26, 2020 — Anaplan, Inc. (NYSE:PLAN), a pioneer in Connected Planning, today announced financial results for its first quarter ended April 30, 2020.

“While our first quarter results reflect the impact of COVID-19, we believe the need for a digital connected planning platform will become even stronger as it is clear that traditional planning no longer works,” said Frank Calderoni, chief executive officer at Anaplan. “We are confident in the demand for our Connected Planning solution as companies look to drive digital change in order to respond and adapt to the rapid pace of change. Our unique calculation engine, committed partner ecosystem, extensive customer base and strong financial position sets us up to drive long-term success.”

First Quarter Fiscal 2021 Financial Results

The company is providing the following guidance for its second quarter fiscal 2021:

With the uncertainty surrounding the ongoing impact of COVID-19 we are withdrawing our previously issued full-year fiscal 2021 guidance provided February 27, 2020.

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.

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: the COVID-19 pandemic, and any resulting global economic downturn, could significantly disrupt our business operations, prolong our sales cycle and result in a material adverse effect on our financial condition, operating results and cash flows; 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; we have a 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; economic uncertainty and volatility in the broader financial markets may result in our customers and prospective customers reducing their spending, scaling back their digital transformation efforts, delaying purchasing decisions or deferring implementation projects, any of which may adversely impact our business, financial condition and cash flows; if we are unable to achieve and sustain a level of liquidity sufficient to support our operations and fulfill our obligations, our business, operating results and financial position could be adversely affected; 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 if we fail to achieve renewals and expansions or our customers renew or expand their subscriptions on less favorable terms, our business operations and financial condition may be materially and adversely affected; 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; our success depends in part on the continued performance of our strategic partners, and uncertain economic conditions including those caused by the COVID-19 pandemic may disrupt the operations and performance of our partners and ultimately adversely impact our financial results; 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; our success depends upon training our customers to effectively utilize our platform and consistently providing high-quality support services and if our ability to provide effective training or support is limited by the COVID-19 pandemic and ensuing remote work restrictions, then our results of operations and financial condition may be adversely affected; 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; and the uncertainty in and volatility of the broader stock market generally or the stock price of our common stock specifically may result in stockholders not being able to resell their shares at or above the price at which they purchased shares. Furthermore, the additional or unforeseen effects from the COVID-19 pandemic and the global economic climate may amplify many of these risks. 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 filings with the U.S. Securities and Exchange Commission (“SEC”), including its annual report on Form 10-K filed with the SEC on March 30, 2020, and other documents the company may file with or furnish to the SEC from time to time such as quarterly reports on Form 10-Q and current reports on Form 8-K.

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 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.
