Subject: Welcome to Microchip!

Today Microchip Technology announced the signing of a definitive agreement to acquire Micrel in a transaction that values Micrel at $14/share. The transaction is subject to the approval of shareholders of Micrel, regulatory approvals and customary closing conditions. We expect the transaction to close early in the third calendar quarter of 2015.

I would like to begin with thanking and recognizing Ray Zinn. Ray founded Micrel and has led the company for the last 37 years. I want to thank Ray for his vision in guiding Micrel from a start-up to almost a quarter billion dollars in annual sales.

We are excited by the business possibilities created by the Micrel acquisition, and we would like to take this opportunity to warmly welcome you all to the Microchip family! One of our guiding values is that employees are our greatest strength, and we look forward to the Micrel team being part of that strength.

Microchip is a leading provider of embedded control solutions through our Microcontroller, Mixed-Signal, Analog, Wired and Wireless connectivity, Flash IP solutions and Memory product lines. Microchip is a ~$2.2 Billion revenue company with over $1.4 Billion revenue in Microcontrollers and over $500M in Analog. As you know, Microcontrollers and Analog go hand in hand in customers’ designs and having both gives the company a strategic advantage. This acquisition adds Micrel’s portfolio of Linear & Power Management products, LAN solutions and Timing & Communications products to Microchip. We believe the complementary product lines of Microchip and Micrel will offer our combined customers a broader range of innovative solutions to serve their needs. Together we believe Microchip and Micrel can win more customers and more markets than what each of us could achieve individually. We are looking forward to working with the Micrel team and continuing to provide challenging and rewarding work at the combined company.

I will be in San Jose, California on May 8, 2015 hosting meetings with the management team of Micrel and Micrel employees as a first introduction of Microchip to you. There will be an employee communication meeting in building 1931 at 10AM on May 8th. Employees should attend this meeting as I will share important information about this acquisition and how your benefits will be converted to Microchip. Other Microchip team members will also start the process of visiting Micrel locations and getting to know more of the team and operations in the weeks to come. Over the next couple of months we will be working closely with Micrel leaders worldwide to develop joint plans for how we can operate even more effectively as one company after the acquisition is completed.

Meanwhile, please continue to stay focused on executing your plans and achieving the results we will build on together after the acquisition is completed. We will provide periodic communication so that you stay informed. We look forward to the future as we bring our two innovative and successful companies together.

Best wishes and welcome to Microchip!
