Tintri Reports Second Quarter Fiscal 2018 Financial Results

MOUNTAIN VIEW, Calif, September 7, 2017 – Tintri, Inc. (NASDAQ: TNTR), a leading enabler of enterprise cloud, today reported results for its second quarter fiscal 2018 ended July 31, 2017.

“While the company’s revenue came in at the low end of our expectations, we delivered stronger than projected profitability and cash flow improvements,” said Ken Klein, Chairman and CEO at Tintri. “We remain confident in our competitive position and in the strength of our value proposition. In the quarter we received the largest order in the company’s history and added new enterprise logos. Additionally, we experienced continued momentum in our land-and-expand strategy with more purchases from current customers. We enter the second half of our fiscal year having just announced a new all-flash platform and additional software offerings—these further enhance our differentiation and better enable our customers to transition to the enterprise cloud.”

Q2 Key Quarterly Business and Financial Highlights

• Quarterly revenue: $34.9 million, up 27% year-over-year.

• Net Loss per Share Attributable to Common Stockholders: ($2.05) per share GAAP, improved from ($7.53) per share in the year-ago quarter; and ($0.91) per share non-GAAP, improved from ($1.03) per share in the year-ago quarter.

• Cash and cash equivalents, and short-term investments: $80.6 million as of July 31, 2017, compared to $48.0 million as of January 31, 2017.

• New customers: added new enterprise and CSP customers, increasing total customer count to over 1,400.

• Launched new enterprise cloud offerings: Tintri EC6000 all-flash storage platform, Tintri Cloud Connector for integration to Amazon Web Services and IBM Cloud Object Storage, and advancements to machine learning powered Tintri Analytics.

Third Quarter Fiscal 2018 Financial Outlook

As we look ahead, we are providing the following outlook for the quarter ending October 31, 2017. We expect:

• Revenue in the range of $36 to $37 million;

• Non-GAAP loss per share in the range of ($0.77) to ($0.81), using 31.2 million weighted-average shares outstanding.

All forward-looking non-GAAP financial measures contained in this section titled “Third Quarter Fiscal 2018 Financial Outlook” exclude stock-based compensation expense, payroll tax expense related to stock-based activities, and, as applicable, other special items. We have not reconciled guidance for non-GAAP loss per share to its most directly comparable GAAP measure because the items that have been excluded are uncertain and cannot be reasonably predicted. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measures is not available without unreasonable effort.

Forward-Looking Statements

This press release contains forward-looking statements, including but not limited to statements relating to estimated revenues and non-GAAP loss per share for future fiscal periods, our competitive position and environment, sales trends, and product releases. These forward-looking statements are not historical facts, and instead are based on our current expectations, estimates, opinions, and beliefs. Consequently, you should not rely on these forward-looking statements. The accuracy of such forward-looking statements depends upon future events, and involves risks, uncertainties, and other factors beyond our control that may cause these statements to be inaccurate and cause our actual results, performance, or achievements to differ materially and adversely from those anticipated or implied by such statements, including, among others: the rapid evolution of the markets in which we compete; our ability to sustain or manage future growth effectively; factors that could result in the significant fluctuation of our future quarterly operating results, including, among other things, our revenue mix, the timing and magnitude of orders, shipments and acceptance of our solutions in any given quarter, our ability to attract new and retain existing end-customers, changes in the pricing of certain components of our solutions, and fluctuations in demand and competitive pricing pressures for our solutions; the introduction or acceleration of adoption of competing solutions; failure to develop, or unexpected difficulties or delays in developing, new product features or technology on a timely or cost-effective basis; and other risks and uncertainties included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the final Prospectus related to our initial public offering of common stock (“IPO”) filed pursuant to Rule 424(b) under the Securities Act of 1933 (Registration No. 333-218429), and other reports on file with the U.S. Securities and Exchange Commission (“SEC”), which are available on our investor relations website at https://ir.tintri.com and on the SEC website at www.sec.gov, or that we may file with the SEC following the date of this press release, including our Quarterly Report on Form 10-Q for the quarter ended July 31, 2017.

Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures and other key performance measures: non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating loss, non-GAAP operating margin, non-GAAP net loss, non-GAAP net loss per share, pro forma non-GAAP net loss per share, free cash flow, and free cash flow as a percentage of revenue. In computing these non-GAAP financial measures, we exclude the effects of certain items such as stock-based compensation expense, IPO-related expenses not netted against IPO proceeds, and adjustment to Series E, E-1, and F Convertible Preferred Stock related to our IPO. Free cash flow is a performance measure that our management believes provides useful information to management and investors about the amount of cash generated by the business after necessary capital expenditures, and we define free cash flow as net cash used in operating activities less purchases of property and equipment. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures and key performance measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Our management believes that these non-GAAP financial measures and key performance measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures such as stock-based compensation expense that may not be indicative of our ongoing core business operating results. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when analyzing historical performance and liquidity, and planning, forecasting, and analyzing future periods. However, these non-GAAP financial and key performance measures have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating loss, non-GAAP operating margin, non-GAAP net loss, non-GAAP net loss per share, pro forma non-GAAP net loss per share, and free cash flow are not substitutes for gross profit, gross margin, operating expenses, loss from operations, operating margin, net loss or net loss attributable to common stockholders, net loss per share or net loss per share attributable to common stockholders, net loss per share or net loss per share attributable to common stockholders, or net cash used in operating activities, respectively. In addition, other companies, including companies in our industry, may calculate non-GAAP financial measures and key performance measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures and key performance measures as tools for comparison. We urge you to review the reconciliation of our non-GAAP financial measures and key performance measures to the most directly comparable GAAP financial measures included below in the tables captioned “Reconciliation of GAAP to Non-GAAP Profit Measures,” and “Reconciliation of GAAP Net Cash Used In Operating Activities to Non-GAAP Free Cash Flow,” and not to rely on any single financial measure to evaluate our business.
