Under the MSA, the Company has agreed to use its best efforts to transition to purchasing Enphase products in accordance with the MSA as soon as possible following execution of the MSA. The MSA does not otherwise restrict the Company from manufacturing, selling or purchasing any goods or products other than as restricted by the exclusivity provisions under the MSA.

Enphase Energy Completes Acquisition of SunPower’s Microinverter Business
Acquisition Brings Together Category Leaders in Residential Installations and Microinverters

PETALUMA, Calif. and SAN JOSE, Calif., Aug. 9, 2018- Enphase Energy, Inc. (NASDAQ:ENPH), and SunPower Corp. (NASDAQ:SPWR), today announced that Enphase has completed the previously announced acquisition of SunPower’s microinverter business for a total of $25 million in cash and 7.5 million shares of Enphase common stock. Key anticipated benefits and highlights of the acquisition include:
Advances AC Modules (ACM) as the future of residential solar
Enhances SunPower’s Equinox™ Home Solar System with a custom line of Enphase’s IQ microinverters for use with SunPower AC Modules
Adds over 140 patents to enhance Enphase’s strong IP portfolio
$15 million of cash purchase price funded from Enphase’s balance sheet at closing and $10 million of cash purchase price to be funded by 12/28/2018

“We are excited to close the acquisition of SunPower’s microinverter business ahead of plan,” said Badri Kothandaraman, president and CEO of Enphase Energy. “We now expect volume shipments of IQ 7XS microinverters in the fourth quarter of 2018 and an acceleration of the ramp throughout 2019. The business is on track to achieve its full revenue and gross margin potential. ACM is a significant component of our profitable top line growth strategy. We look forward to being a strong innovation partner for SunPower.”
IQ 7 is Enphase’s seventh-generation microinverter platform leading the industry with its software-defined architecture, broad regulatory compliance and advanced “Smart Grid” features.
