MICROCHIP TECHNOLOGY TO ACQUIRE ATMEL

• Creates Microcontroller, Analog and IOT Powerhouse

• Immediately accretive to non-GAAP earnings per share

• Estimated $170 million in synergies in fiscal year 2019 that begins on April 1, 2018

Chandler, Arizona and San Jose, California – January 19, 2016 – Microchip Technology Incorporated (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, and Atmel Corporation (NASDAQ: ATML) today announced that Microchip has signed a definitive agreement to acquire Atmel for $8.15 per share in a combination of cash and Microchip common stock. The acquisition price represents a total equity value of about $3.56 billion, and a total enterprise value of about $3.40 billion, after excluding Atmel’s cash and investments net of debt on its balance sheet of approximately $155.0 million at December 31, 2015.

“We are delighted to welcome Atmel employees to Microchip and look forward to closing the transaction and working together to realize the benefits of a combined team pursuing a unified strategy. As the semiconductor industry consolidates, Microchip continues to execute a highly successful consolidation strategy with a string of acquisitions that have helped to double our revenue growth rate compared to our organic revenue growth rate over the last few years. The Atmel acquisition is the latest chapter of our growth strategy and will add further operational and customer scale to Microchip,” said Steve Sanghi, President and CEO of Microchip.

“Microchip and Atmel have a strong tradition of innovation, stretching across microcontroller, analog, touch, connectivity and memory solutions. Joining forces and combining our product portfolios will offer our customers a richer set of solution options to enable innovative and competitive products for the markets they serve,” said Ganesh Moorthy, COO of Microchip.

“Our Board of Directors determined, after consultation with our financial advisor and outside legal counsel, that the transaction with Microchip is a superior proposal for Atmel’s stockholders under the

terms of our merger agreement with Dialog Semiconductor plc that we terminated today. Under the Microchip transaction, Atmel stockholders will receive a much higher cash consideration per share compared to the Dialog deal, as well as the opportunity for further upside through the ownership of stock of Microchip,” said Steven Laub, President and CEO of Atmel.

Concurrent with this announcement, Microchip announced that its Board of Directors has authorized an increase in the existing share repurchase program to 15.0 million shares of common stock from the approximately 11.4 million shares remaining under the prior authorization. Under this program, in the next several months, Microchip intends to repurchase the approximate number of shares it issues in the Atmel acquisition, which is expected to result in the transaction having the accretive effects of a cash transaction from a financial perspective.

Following the closing, the transaction is expected to be immediately accretive to Microchip’s non-GAAP earnings per share. Based on currently available information, Microchip anticipates achieving an estimated $170 million in synergies from cost savings and incremental revenue growth in fiscal year 2019 that begins on April 1, 2018.

The transaction has been approved by the Board of Directors of each company and is expected to close in the second quarter of calendar year 2016, subject to approval by Atmel’s stockholders, regulatory approvals and other customary closing conditions. No approval by Microchip’s stockholders is required in connection with the transaction. The transaction is not subject to any financing conditions.

Transaction Details

In the transaction, stockholders of Atmel will receive $7.00 per share in cash and $1.15 per share in Microchip common stock, valued at the average closing price for a share of Microchip common stock for the ten most recent trading days ending on the last trading day prior to the closing, with the maximum number of Microchip shares to be issued in the transaction being 13.0 million. To the extent that the number of Microchip shares issuable would exceed 13.0 million, the cash consideration per Atmel share will be increased such that the value of the combined cash and stock consideration will remain at $8.15 per share (as valued based upon the average closing price described in the previous sentence). Microchip expects to fund the cash portion of the purchase price through a combination of cash on its balance sheet and borrowings under its existing credit facility.
