U.S. Auto Parts Appoints Lev Peker to Chief Executive Officer

CARSON, Calif. — November 28, 2018 — U.S. Auto Parts Network, Inc. (NASDAQ: PRTS), one of the largest online providers of aftermarket automotive parts and accessories, has appointed Lev Peker as director and chief executive officer, succeeding Aaron Coleman effective January 2, 2019.

Peker brings considerable marketing and operational expertise to U.S. Auto Parts, having previously served as chief marketing officer of Adorama, a leading online destination for photography, imaging, audio and consumer electronics, as well as senior director and general manager of e-commerce strategy and operations at Sears.

This will be Peker’s second stint with U.S. Auto Parts, having previously held various managerial positions on the finance and online marketplace teams from 2008 to 2014.

U.S. Auto Parts Chairman Barry Phelps commented: “Lev has a strong track record of driving growth through both traditional and digital marketing channels. During his time at Adorama, he was instrumental in improving the company’s visibility across retail, online, mobile and social media channels, while also serving as the architect behind the company’s content strategy and marketing campaigns to boost traffic and conversion. Given his previous tenure with U.S. Auto Parts, his familiarity of our business and competitive dynamics will enable him to hit the ground running.”

“I would like to thank Aaron Coleman for his many years of service to U.S. Auto Parts. He has been an exceptional executive for our company for more than 10 years, and we wish him all the best in his future endeavors.”

Peker commented on his appointment: “U.S. Auto Parts has been serving customers for more than 20 years and has established itself as one of the premier online providers of aftermarket auto parts. We have a strong foundation to build on with millions of orders every year across a diversified range of sales channels, including several owned and operated e-commerce sites and multiple online marketplaces like eBay, Amazon and Wal-Mart. I look forward to leveraging my e-commerce and marketing experience to return U.S. Auto Parts to growth and maximize shareholder value.”
