Management Qualitative Comments

“This is an exciting and promising time for InvenSense,” said Behrooz Abdi president and CEO. “Our design win portfolio continues to grow, positioning us for strong market share increases in the coming quarters as new designs ramp into volume production. We continue to transition to a platform solution company, underscored by our announcement earlier this quarter of our intention to acquire two leading sensor algorithm and software companies. These highly strategic acquisitions allow us to scale our research and development efforts in this area and deliver higher value solutions to our customers. In total, our expanding presence in key geographic markets, additional content opportunities within the mobile device market and new applications for motion and audio sensors, such as wearables, provide healthy growth drivers through the current fiscal year and beyond.”

Financial Highlights

Management believes that certain other financial information is useful when evaluating business results and provides supplemental information on a non-GAAP (generally accepted accounting principles) basis. Non-GAAP net income for the first quarter fiscal 2015 was $7.0 million, or $0.08 per diluted share. This compares to non-GAAP net income of $12.7 million, or $0.14 per diluted share for the first quarter fiscal 2014. Non-GAAP adjustments for the first quarter fiscal 2015 totaling $11.9 million, primarily included $7.7 million of stock-based compensation expense, $0.7 million of litigation expenses, $1.8 million of accretion interest expense on convertible notes, $0.1million amortization of acquired inventory fair value write-up, $1.2 million amortization of acquisition intangibles in connection with the Company’s acquisition of the microphone business line of Analog Devices, Inc. in fiscal 2014, $1.0 million of expenses related to the recently announced acquisitions (Movea and Trusted Positioning, Inc.) partially offset by the related income tax effect of Non-GAAP adjustments of $0.9 million. The reconciliation between GAAP and non-GAAP net income (loss) for all referenced periods is provided in a table immediately following the Unaudited GAAP Condensed Consolidated Statements of Operations below.

Note Regarding Use of Non-GAAP Financial Measures

As discussed above, in addition to the company’s condensed consolidated financial statements, which are presented according to GAAP, the company provides certain non-GAAP financial information that excludes, stock-based compensation expense, litigation expense, business acquisition costs, amortization of fair value write-up of acquired inventory, amortization of acquisition-related intangible assets, accretion interest expense on convertible notes and other non-GAAP financial adjustments. The company uses these non-GAAP measures in its own financial and operational decision-making processes. Further, the company believes that these non-GAAP measures offer an important analytical tool to help investors understand the company’s core operating results and trends, and to facilitate comparability with the operating results of other companies that provide similar non-GAAP measures. These non-GAAP measures have certain limitations as analytical tools and are not meant to be considered in isolation or as a substitute for GAAP financial information. For example, stock-based compensation is an important component of the company’s compensation mix, and will continue to result in significant expenses in the company’s GAAP results for the foreseeable future, but is not reflected in the non-GAAP measures. Also, other companies, including companies in InvenSense’s industry, may calculate non-GAAP financial measures differently, limiting their usefulness as comparative measures.
