With approximately 20.9%(a) of the large-sized TFT-LCD market share, the post-merger AUO will be able to leverage its competitive power to not only integrate Taiwan’s TFT-LCD industry resources but also provide worldwide customers better products, technology and service.

Mr. KY Lee and Mr. HB Chen remain as Chairman/CEO and President/COO of the post-merger AUO, respectively. Post-merger, AUO will rank as the world’s No. 1 maker of large-sized TFT-LCD panels with an estimated market share of approximately 20.9%; AUO will also rank as the world’s No. 1 maker of notebook TFT-LCD panels with a market share of over 25%.

In addition, AUO’s global workforce will increase from approximately 29,000 to more than 42,000 employees after the merger.

Mr. HB Chen said, “Five years ago, AUO was formed by the merger of Acer Display Technology, Inc. and Unipac Optoelectronics Corporation. This time, on the basis of previous merger experience, we have already carried out the integration of R&D resources, site management, supply chain management, product mix, and customer portfolios. Together with our state-of-the-art fabs, we will strive to leverage our strength to keep our pulse on trends in the market and to provide our customers with tailor-made solutions that are both technologically and strategically advantageous.”
