“John is well respected within our organization, including among the executive team,” said Dr. Wang. “Not only does John have an extensive finance background, he knows our company and business intimately and brings a forward-thinking mindset coupled with a passion for fostering a high-performance culture. We are confident that John will continue to be a valuable contributor as we seek to drive our transformation forward and grow shareholder value,” continued Dr. Wang.
