Hortonworks Reports Financial Results for Third Quarter 2016

SANTA CLARA, Calif.—November 3, 2016—Hortonworks, Inc.^® (NASDAQ: HDP), a leading innovator of open and connected data platforms, today announced financial results for the third quarter of 2016.

“Q3 was a milestone quarter for Hortonworks. We crossed the 1,000 customer count and our operating billings grew 66% year-over-year,” said Rob Bearden, chief executive officer and chairman of the board of directors of Hortonworks. “Customers in 60 countries have selected our connected data platforms to leverage a comprehensive data management strategy spanning on-premise, hybrid and public cloud environments. As we continue to work within the Apache Software Foundation to enhance the value to our customers, we are looking forward to future achievements in product functionality and the benefits to be derived from our industry leading solutions.”

Third Quarter 2016 Financial Highlights

• Revenue: Total GAAP revenue was $47.5 million for the third quarter of 2016, an increase of 47 percent compared to the third quarter of 2015.

• Operating Billings: Operating billings, the aggregate value of all invoices sent to our customers in a given period, were $72.5 million for the third quarter of 2016, an increase of 66 percent compared to the third quarter of 2015. We have historically disclosed gross billings as a non-GAAP financial measure that presented total revenue plus the change in deferred revenue for the same period. One would need to add our revenue to our change in deferred revenue to calculate a number that is comparable to our historically reported gross billings numbers.

• Gross Profit: Total GAAP gross profit was $27.7 million for the third quarter of 2016, compared to gross profit of $17.5 million for the same period last year. Non-GAAP gross profit was $29.1 million for the third quarter of 2016, compared to $18.3 million for the same period last year. GAAP gross margin was 58 percent for the third quarter of 2016, compared to 54 percent for the same period last year. Non-GAAP gross margin was 61 percent for the third quarter of 2016, compared to 57 percent for the same period last year.

• Operating Loss: GAAP operating loss totaled $64.4 million for the third quarter of 2016, compared to a loss of $45.2 million for the same period last year. Non-GAAP operating loss was $39.9 million for the third quarter of 2016, compared to a loss of $33.3 million for the same period last year.

• Net Loss: GAAP net loss for the third quarter of 2016 was $64.7 million, or $1.10 per basic and diluted share, compared to a net loss of $45.3 million, or $1.03 per basic and diluted share, in the third quarter of 2015. Non-GAAP net loss was $40.2 million for the third quarter of 2016, or $0.68 per basic and diluted share, compared to a net loss of $33.3 million, or $0.76 per basic and diluted share, for the same period last year.

• Deferred Revenue: Deferred revenue was $156.8 million as of September 30, 2016, a 47 percent increase over the $106.8 million reported as of December 31, 2015 and a 70 percent increase over the $92.1 million reported as of September 30, 2015.

• Cash & Investments: Cash and investments totaled $95.6 million as of September 30, 2016, compared to $96.9 million as of December 31, 2015 and $116.3 million as of September 30, 2015.

A reconciliation of GAAP to non-GAAP financial measures has been provided in the financial statement tables included in this press release.

Financial Outlook

As of November 3, 2016, Hortonworks is providing the following financial outlook for its fourth quarter of 2016 and full year 2016:

For the fourth quarter of 2016:

We expect total GAAP revenue to be $48.0 million.

We expect operating billings, the aggregate value of all invoices sent to our customers in a given period, to be $81.0 million.

We have historically provided guidance for Adjusted EBITDA, which we calculated as revenue plus change in deferred revenue minus non-GAAP expenses plus depreciation. Through the last quarter of 2016, when we expect to achieve Adjusted EBITDA breakeven, we will guide to each element of Adjusted EBIDTA for the fourth quarter of 2016 separately, as follows:

GAAP Revenue:	$48.0 million
Change in deferred revenue:	$33.0 million
Non-GAAP expenses:	$83.0 million
Depreciation:	$2.0 million

For the full year 2016:

We currently estimate our total GAAP revenue to be $180.5 million.

We estimate operating billings, the aggregate value of all invoices sent to our customers in a given period to be $269.4 million.

We have historically provided guidance for Adjusted EBITDA, which we calculated as revenue plus change in deferred revenue minus non-GAAP expenses plus depreciation. Through the last quarter of 2016, when we expect to achieve Adjusted EBITDA breakeven, we will guide to each element of Adjusted EBIDTA for the full year 2016 separately, as follows:

GAAP Revenue:	$180.5 million
Change in deferred revenue:	$83.0 million
Non-GAAP expenses:	$331.9 million
Depreciation:	$7.2 million

Hortonworks has not reconciled its expectations as to non-GAAP expenses to its most directly comparable GAAP measure because of the uncertainty regarding, and the potential variability of, certain costs and expenses that may be incurred in the future, such as stock-based compensation and litigation expenses. Accordingly, reconciliation is not available without unreasonable time and effort, although these factors could be material to Hortonworks’ results computed in accordance with GAAP.

Third Quarter 2016 Earnings Conference Call and Webcast Details

Hortonworks will hold a conference call and webcast today to discuss the Q3 results, Q4 and FY 2016 outlook and related matters at 1:30 p.m. Pacific Time (4:30 p.m. Eastern Time) on Thursday, November 3, 2016. Interested parties may access the call by dialing (877) 930-7786 in the U.S. or (253) 336-7423 from international locations. In addition, a live audio webcast of the conference call will be available on the Hortonworks Investor Relations website at http://investors.hortonworks.com.

Statement Regarding Use of Non-GAAP Financial Measures

Hortonworks reports non-GAAP results for gross profit and margins, operating loss and margins, net loss and, basic and diluted net loss per share in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

Hortonworks’ financial measures under GAAP include stock-based compensation expense, acquisition-related items, amortization of intangible assets, depreciation expense, and other income/expense, net. Management believes the presentation of operating results that exclude these items provides useful supplemental information to investors and facilitates the analysis of the Company’s core operating results and comparison of operating results across reporting periods. Management also believes that this supplemental non-GAAP information is therefore useful to investors in analyzing and assessing the Company’s past and future operating performance.

Non-GAAP cost of revenue is calculated as GAAP cost of revenue less stock-based compensation expense and amortization of intangibles. Management believes non-GAAP cost of revenue offers investors useful supplemental information regarding the performance of our business, and will help investors better understand our business.

Non-GAAP gross profit is calculated as non-GAAP revenue less our non-GAAP cost of revenue. Management believes non-GAAP gross profit offers investors useful supplemental information to help compare our recurring core business operating results over multiple periods.

Non-GAAP gross margin is calculated as non-GAAP gross profit divided by non-GAAP revenue. Management believes that non-GAAP gross margin offers investors useful supplemental information in evaluating our ongoing operational performance, and will help investors better understand our underlying business.

Non-GAAP expenses is calculated as GAAP cost of revenue plus stock-based compensation expense and amortization of intangibles plus GAAP operating expenses plus stock-based compensation expense and amortization of intangibles. Management believes non-GAAP expenses offers investors useful supplemental information regarding the cost structure of our business, and will help investors better understand our business.

Non-GAAP operating loss is calculated as GAAP operating loss plus GAAP revenue adjustments and non-GAAP cost of revenue and operating expense adjustments. The Company believes that non-GAAP operating loss is a useful metric for management and investors because it excludes the effect of stock-based compensation expense, acquisition-related retention bonus, amortization of intangibles and other nonrecurring items so that our management and investors have a greater visibility to the underlying performance of the business operations.

Non-GAAP operating margin is calculated as non-GAAP operating loss divided by non-GAAP revenue. Management believes that non-GAAP operating margin offers investors useful supplemental information in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods.

Non-GAAP net loss is calculated as GAAP net loss plus GAAP revenue adjustments and non-GAAP cost of revenue and operating expense adjustments. Management believes non-GAAP net loss offers investors useful supplemental information to help identify trends in our underlying business and perform related trend analyses.

Non-GAAP net loss per basic and diluted share is calculated as non-GAAP net loss divided by the weighted-average shares outstanding for the period. Management believes non-GAAP net loss per basic and diluted share offers investors useful supplemental information, and will help investor better understand our performance and return to shareholders.
