 What We Just Announced  Integrated Device Technology to acquire GigPeakApproved by both Management teams and Board of DirectorsProcess started for government approvals and acquiring shares (tender offer)Expected to close during the 2nd calendar quarter of 2017We intend to grow GigPeak’s business, and are interested in all of itFrom an IDT perspective, GigPeak isn’t a new strategyIt accelerates our current strategyWe can now provide ultra-high speed interconnect using electrons, radio, and photons – a unique and valuable position ! 

 5  Questions You May Have  Will there be job loss?We’re very impressed with GigPeak peopleYes, there will be some but very little, and mainly in G&A. IDT will actively help everyone in this process No R&D change. Marketing / bus-dev and sales is also complimentary to our ownWill IDT invest to grow our business?Yes. We expect commitment to grow along with new investment. We wouldn’t be doing this if we didn’t think we could grow faster togetherWho will my boss(es) be?Pretty much the same ones you know already This will be run as a standalone business, led by Raluca Dinu who will report to Sean Fan, head of IDT Computing & Communications DivisionThere’s a lot of opportunity to leverage GigPeak IP and knowledge into other IDT businesses too – we’ll figure those out together
