LG Innotek invests $67.9m to expand auto chip plant in Korea

LG Innotek will invest 100 billion won (US$67.9 million) to expand its automotive application processor (AP) module production facility in Gwangju, South Korea.

The company signed a memorandum of understanding with the Gwangju Metropolitan Government to add new AP module production lines, with the expanded site set to open in December.

Automotive AP modules act as the control center for vehicle electronics and are a recent business area for LG Innotek.

In March 2025, the company outlined a separate 600 billion won (US$405,88 million) investment to expand production in Gumi, focusing on flip-chip ball grid array and high-value camera modules, with completion planned by year-end.

🧠 Food for thought

Implications, context, and why it matters.

AP module push lacks disclosed design-ins or platforms

  • LG Innotek started shipping automotive AP modules to global chipmakers late last year 1. No anchor customers, design-ins (formal selection of a supplier’s component for a vehicle program) or named silicon platforms from Qualcomm, Nvidia, Renesas, or Samsung are public.
  • The $67.9 million capex lacks visibility on timing or revenue. Auto programs often take 2 to 3 years from design-in to start of production.
  • Vehicle AP modules could grow about 22 percent a year 1. Few suppliers can build at scale today, so early share depends on winning original equipment manufacturer (OEM) programs. There is no public detail on ISO 26262, Automotive Electronics Council Q-series qualifications (AEC-Q) or capacity goals for the December 2026 opening.

Vendors can target LG Innotek’s new Gwangju lines

  • Vendors of manufacturing execution systems (MES) and automated test and inspection gear can pursue the new lines. Thermal materials and electromagnetic interference (EMI) shielding run through LG’s SINGLEX portals (LG’s centralized procurement system), including procurement-lgit.singlex.com 23.
  • The Gwangju buildout opens in December 2026 and lifts total floor area to about 97,000 square meters 1. Equipment suppliers can prepare bids for installation tenders in the coming months.
  • Consultancies in functional safety and automotive cybersecurity can target centralized vehicle compute. Focus on ISO 26262 plus United Nations Economic Commission for Europe (UNECE) R155 and R156 milestones that OEMs must meet for autonomous, connected vehicle programs.
