Dear Employees,

I am very pleased to share some exciting news with you. Today, it was announced that Quantenna is being acquired by ON Semiconductor for $24.50 per share in an all cash transaction valued at approximately $1.1 billion, subject to customary closing conditions. ON is one of the world’s leading semiconductor companies headquartered in Phoenix, AZ with multiple offices around the world. In 2018, ON generated $5.9 billion in revenue, addressing fast-growing markets such as automotive, industrial, cloud, and 5G. You can find out more information about the transaction here

Since its founding in 2006, Quantenna has been a leading innovator in Wi-Fi technology, introducing market disruptive solutions that have raised the bar on high performance connectivity. Today’s announcement highlights our technology leadership in Wi-Fi and the outstanding achievements of Quantenna’s talented team of employees, representing almost two thousand-man years of R&D and IP development. Now, we are ready for the next phase of our evolution. Together with ON, we look forward to broadening our market reach, expanding our technology development and delivering industry leading products to the benefit of current and new customers. The combination of ON’s scale, market leadership, and world-class quality and customer support organization, together with our talented employees, Wi-Fi solutions and complementary technologies, will allow us to take innovation to the next level and address new and existing customer opportunities.

Finally, again, I am very excited about this event and as we continue to work to close the transaction over the next several months, we will be operating with our usual level of commitment, smarts and hard work. It continues to be our top priority to not only meet but exceed our goals.

We should all be very proud of what we have achieved as a team, and this was only made possible by the great contributions each one of you has made. This is a great day for Quantenna, and the beginning of the next chapter for us to continue and make “Wi-Fi perfected.”

Over the next couple of days, we will be holding a variety of meetings including an all hands meeting on Thursday that will include some of the ON senior leadership. Invites will be sent out shortly. If you have any questions, please don’t hesitate to reach out to me or your manager.

Best regards
