Synaptics Reports Results for Fourth Quarter and Fiscal 2015

• Record fiscal 2015 revenue of $1.7 billion up 80 percent

• Record June quarter revenue of $479 million up 52 percent year-over-year

• Record fiscal 2015 non-GAAP EPS of $5.69; GAAP EPS of $2.89

• Increases available stock repurchase authorization to $198 million

SAN JOSE, Calif. – July 30, 2015 – Synaptics (NASDAQ: SYNA), a leading developer of human interface solutions, today reported financial results for its fourth quarter and year ended June 30, 2015.

“Synaptics posted a strong fourth quarter and a phenomenal fiscal year as we crossed the $1 billion annual revenue threshold,” stated Rick Bergman, President and CEO. “During fiscal 2015 we surpassed the 3 billion milestone for unit shipments of our solutions, more than doubled the revenue contribution from China based mobile customers and also doubled revenue from our fingerprint ID business. We successfully completed and integrated the acquisition of our display driver business, strengthening our competitive position and accelerating our roadmap for touch and display driver integration.

“Our focus remains on growth, and we continue to invest in order to fully capitalize on our key fingerprint ID and touch and display driver integration (TDDI) growth pillars as we march towards becoming a $2 billion annual revenue company. With our continued commitment to growth and innovation, we expect to generate a strong top-line increase in fiscal 2016 of 20 percent to 25 percent, with growth weighted towards the second half of the fiscal year based on our strong product pipeline,” concluded Mr. Bergman.

Net revenue for fiscal 2015 reached a record $1.7 billion, an increase of 80 percent over fiscal 2014. Net income for fiscal 2015 was $112.3 million, or $2.89 per diluted share.

Non-GAAP net income for fiscal 2015 increased 40 percent from the prior year to a record $221.4 million, or $5.69 per diluted share. (See attached table for a reconciliation of GAAP to non-GAAP financial measures.)

Net revenue for the fourth quarter of fiscal 2015 grew 52 percent over the comparable quarter last year to a record $478.9 million. Net income for the fourth quarter of fiscal 2015 was $33.3 million, or $0.85 per diluted share.

Non-GAAP net income for the fourth quarter of fiscal 2015 grew 8 percent over the prior year period to $61.2 million, or $1.57 per diluted share. (See attached table for a reconciliation of GAAP to non-GAAP financial measures.)

Fourth Quarter 2015 Business Metrics

• Revenue mix from mobile and PC products was approximately 89 percent and 11 percent respectively. Fingerprint ID products have been classified according to type of device.

• Revenue from mobile products of $426.6 million was up 76 percent year-over-year. Mobile products revenue includes all touchscreen, display driver, and applicable fingerprint ID products.

• Revenue from PC products totaled $52.3 million, a decrease of 27 percent year-over-year, and includes applicable fingerprint ID products.

• Cash at June 30, 2015 was $400 million.

Wajid Ali, CFO, added, “Considering our backlog of $159 million entering the typically back-end loaded September quarter, subsequent bookings, customer forecasts and product sell-in and sell-through timing patterns, and the resulting expected product mix, we anticipate revenue to be in the range of $450 to $490 million, an increase of 59 percent to 73 percent over the prior year period. On a sequential basis, this outlook reflects positive trends in our touch and fingerprint products despite typical downward seasonality, offset by product cycle trends in display driver products. We expect the revenue mix from mobile and PC products to be roughly similar to the preceding quarter.”

During fiscal 2015, Synaptics repurchased approximately 5 percent of its outstanding shares, similar to levels repurchased during each of the past several years. The company also announced that in July, its board of directors increased and extended the authorization for stock repurchases by $120 million, for a total current authorization of $198 million available through July 2017.

Use of Non-GAAP Financial Information

In evaluating its business, Synaptics considers and uses net income excluding share-based compensation, change in contingent consideration, and certain non-cash or non-recurring items as a supplemental measure of operating performance. Net income excluding share-based compensation, change in contingent consideration, and certain non-cash or non-recurring items is not a measurement of the company’s financial performance under GAAP and should not be considered as an alternative to GAAP net income. The company presents net income excluding share-based compensation, change in contingent consideration, and certain non-cash or non-recurring items because it considers it an important supplemental measure of its performance. The company believes this measure facilitates operating performance comparisons from period to period by eliminating potential differences in net income caused by the existence and timing of share-based compensation charges, change in contingent consideration, and certain non-cash or non-recurring items. Net income excluding share-based compensation, change in contingent consideration liability, and certain non-cash or non-recurring items has limitations as an analytical tool and should not be considered in isolation or as a substitute for the company’s GAAP net income. The principal limitations of this measure are that it does not reflect the company’s actual expenses and may thus have the effect of inflating its net income and net income per share.
