MobileIron Raises Q3 Guidance

MOUNTAIN VIEW, Calif., October 10, 2016 - MobileIron (NASDAQ:MOBL), the stand-alone enterprise mobility management (EMM) leader, today raised guidance for the third quarter of the fiscal year 2016 ended September 30, 2016.

Third Quarter 2016 Preliminary Results

Gross billings for the quarter are expected to be in the range of $46.5-$47.5 million, above the company's previous guidance of $43-$45 million. Total revenues are anticipated to be between $41.0-$42.0 million, above the previous guidance of $39-$41 million. Non-GAAP operating expenses are expected to be at the low end of the company’s guidance of $41-$43 million. The company ended the quarter with cash and cash equivalents plus short-term and long-term investments of approximately $80 million for a sequential reduction of roughly $6 million.

These preliminary, unaudited financial results are based on management's initial review of operations for the quarter ended September 30, 2016, and remain subject to change based on management's ongoing review of the third quarter results.

"We’ve spent the last year putting together a new executive team, differentiating our platform, refining our go-to-market strategy and focusing on execution. There’s a big market in front of us and our results this quarter demonstrate that we’re winning,” said Barry Mainz, President and CEO, MobileIron. "We’re very pleased with Q3 and we believe we’re on track to be cash flow positive in the fourth quarter. I look forward to providing details on our regularly scheduled quarterly earnings conference call on October 27."

While a reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis, MobileIron will provide a reconciliation of GAAP to non-GAAP financial measures in its quarterly earnings release for Q3.
