Synaptics Reports Results for Second Quarter of Fiscal 2011

•

Record revenue, up 20% year-over-year

•

Revenue from mobile touchscreen applications more than doubles year-over-year to new high

•

Approximately 4% of total shares outstanding repurchased under stock buyback program

Santa Clara, CA — January 20, 2011 — Synaptics (NASDAQ: SYNA), a leading developer of human interface solutions for mobile computing, communications, and entertainment devices, today reported financial results for its second fiscal quarter ended December 31, 2010.

Net revenue for the second quarter of fiscal 2011 was a record $159.6 million, an increase of 20% compared with $133.3 million for the comparable quarter last year. Net income for the second quarter of fiscal 2011 was $17.7 million, or $0.50 per diluted share, compared with net income of $12.2 million, or $0.35 per diluted share, for the comparable quarter last year.

Non-GAAP net income for the second quarter of fiscal 2011 was $25.4 million, or $0.72 per diluted share, compared with non-GAAP net income of $21.7 million, or $0.62 per diluted share, for the second quarter of fiscal 2010. (See attached table for a reconciliation of GAAP to non-GAAP results.)

“We are very pleased with our overall performance in the first half of the year,” stated Russ Knittel, Interim President and CEO. “During the second quarter, revenue from the PC market was weaker than anticipated, reflecting continued softness in consumer notebook demand, while revenue from mobile touchscreen applications more than doubled year-over-year and reached the highest quarterly level to date. We have made strong progress on our key initiatives to expand our capabilities and to position ourselves to meet the growing and evolving market dynamics.”

Non-PC revenue of $88.6 million represented 55% of total revenue for the second quarter, an increase of 48% over the comparable quarter last year. Non-PC revenue consisted almost entirely of revenue from mobile phone applications, as the number of mobile phone models shipping with Synaptics’ touchscreen solutions continued to expand. PC revenue of $71.0 million decreased 4% from the comparable quarter last year and represented 45% of total revenue for the quarter.

Cash at December 31, 2010 totaled $216.4 million. Cash flow from operations for the quarter was $24.3 million. The Company used $40.2 million to buy back approximately 1.5 million shares of its common stock under its stock repurchase program.

Kathy Bayless, CFO, added, “Considering our backlog of approximately $92 million entering the March quarter, expected product mix, and customer forecasts, we anticipate revenue of $136 million to $146 million for the third fiscal quarter, representing an increase of 17% to 26% over the comparable quarter last year. Our outlook reflects strong year-over-year growth and seasonality in the March quarter.”

Use of Non-GAAP Financial Information

In evaluating its business, Synaptics considers and uses net income per share excluding share-based compensation, non-cash interest charges, and unusual or non-recurring items as a supplemental measure of operating performance. Net income excluding share-based compensation, non cash interest charges, and unusual 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, non-cash interest charges, and unusual 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 non-cash compensation charges, non-cash interest charges, and unusual or non-recurring items. Net income excluding share-based compensation, non-cash interest charges, and unusual 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.
