Synergy and Accretion Expectations

Transaction is expected to be immediately accretive to our non

GAAP earnings per share

Short term: Targeting 18% growth in non-GAAP EPS from FY16 to

FY17 with accretion from Micrel and Atmel.

Atmel adds ~25 cents in FY 2017

Long term: 3rd year after close (FY2019), we expect:

$170M in synergy from cost savings and revenue growth

Atmel to contribute ~90 cents/share of non GAAP EPS (this assumes

shares issued in the Atmel transaction are purchased back prior to

FY19)

Targeting consolidated Microchip non GAAP EPS of $4.25/share

Represents non GAAP EPS growth of over 17% per year for

Microchip over the next 3 years.

Full synergy of over $200M in the 4th year (FY 2020)

Extends Microchip’s record of organic as well as acquisition driven

revenue and non GAAP EPS growth
