Silicon Motion Announces New Organizational Structure to Support

Continued Global Business Growth

Establishes Two Dedicated Business Units and Appoints Senior Leaders to Oversee

Growth and Further Market Expansion

TAIPEI, Taiwan and MILPITAS, Calif., Dec. 11, 2023 – Silicon Motion Technology Corporation (NasdaqGS: SIMO) (“Silicon Motion, “the “Company” or “we”), a global leader in designing and marketing NAND flash controllers for solid-state storage devices, today, announced a new organizational structure and leadership team appointments to support the Company’s continued global business growth. These changes will take effect immediately.

Core to this announcement is the establishment of two business units designed to create a more focused and specialized structure that should enable faster innovation and stronger growth and support the Company’s commitment to delivering the best-in-class solutions for its customers. The Client & Automotive Storage (“CAS”) Business Unit will house the Company’s client SSD controllers, mobile controllers, Ferri products and expandable controllers. The Enterprise Storage & Display Interface Solution (“ESDI”) Business Unit will encompass the Company’s enterprise SSD controllers and display interface products.

As part of the new organizational structure, Silicon Motion has created the following leadership roles:

“The increasing adoption of NAND in consumer, industrial, commercial and enterprise applications continue to expand our opportunities for growth,” said Wallace Kou, President and CEO of Silicon Motion. “By creating these two dedicated business units, we will be even better positioned to develop the most advanced controller technology and deliver industry-leading solutions for our customers. Today, we see a unique opportunity to expand into new markets and increase share in our existing businesses, and with this new structure, we will be able to do so quicker and more effectively to drive our long-term success.”
