Santa Clara, CA — July 29, 2010 — Synaptics (Nasdaq: SYNA), a leading developer of human interface solutions for mobile computing, communications, and entertainment devices, today reported financial results for the fourth quarter and year ended June 30, 2010.

Net revenue of $145.8 million in the fourth quarter of fiscal 2010 was a record, an increase of 26% over $115.3 million a year ago and an increase of 25% from $116.2 million, sequentially. Net income in the fourth quarter of fiscal 2010 was a record $19.3 million, or $0.54 per diluted share, compared with $12.4 million, or $0.34 per diluted share, a year ago and net income of $11.6 million, or $0.33 per diluted share, in the third quarter of fiscal 2010.

Non-GAAP net income in the fourth quarter of fiscal 2010 was $24.8 million, an increase of 44% over the prior year and an increase of 52% from the previous quarter. Non-GAAP net income per diluted share was $0.70 in the fourth quarter of fiscal 2010, an increase of 49% over the prior year and an increase of 52% compared with the previous quarter. (See attached table for a reconciliation of GAAP to non-GAAP results.)

“Synaptics capped off fiscal 2010 with the highest revenue quarter in our history as we experienced strong growth for both notebook and mobile applications,” stated Tom Tiernan, President and CEO. “As the innovation leader in human interface solutions, Synaptics continues to win in the market based on our unique solutions approach, our portfolio fulfillment model, the strength and reliability of our technology, and our proven ability to execute.”

Mr. Tiernan added, “Fiscal 2011 is off to a strong start, and we anticipate setting a new revenue record in the first quarter. We are pleased to have recently announced compelling new technology for large touchscreens and remote controls, both of which we expect to be new sources of revenue in fiscal 2011.”

PC revenue of $84.6 million represented 58% of total revenue for the fourth quarter and increased 29% from the comparable quarter last year. Non-PC revenue of $61.2 million increased 23% from the comparable quarter last year and comprised 42% of total revenue for the quarter. Mobile phone applications comprised 40% of the Company’s revenue, and the number of mobile phone models shipping with Synaptics’ touchscreen solutions reached a new high.

Net revenue for fiscal 2010 was $514.9 million, an increase of 9% over $473.3 million for fiscal 2009. Net income for fiscal 2010 was $53.0 million, an increase of 10% over $48.1 million for fiscal 2009. Net income per diluted share was $1.50, an 11% increase over net income per diluted share of $1.35 for fiscal 2009.

Non-GAAP net income for fiscal 2010 was $80.0 million compared with $77.9 million for fiscal 2009. Non-GAAP net income per diluted share was $2.26 compared with $2.19 in 2009. (See attached table for a reconciliation of GAAP to non-GAAP results.)

Kathy Bayless, CFO, added, “Considering our backlog of approximately $85 million entering the September quarter, expected product mix, and customer forecasts, we anticipate revenue in the quarter of $148 million to $156 million, an increase of 24% to 30% over the comparable quarter last year. With a strong start to the year and anticipated continued solid demand for our core notebook and mobile phone applications, we expect our fiscal 2011 revenue growth rate to accelerate over last year to at least the low double-digits to mid-teens.”

Use of Non-GAAP Financial Information
In evaluating its business, Synaptics considers and uses net income per share excluding share-based compensation and unusual or non-recurring items as a supplemental measure of operating performance. Net income excluding share-based compensation 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 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 and unusual or non-recurring items. Net income excluding share-based compensation 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.
