Taiwan's Unimicron is riding an AI-driven shortage of chip substrates, a clear positive for the company and its investors.

• August revenue hit another record, up 56% from a year ago, the fifth record month in a row.
• Demand for ABF substrates — the boards that carry AI and high-speed computing chips — is outrunning supply.
• Revenue for the first eight months of the year is up 34%.
• Unimicron plans rolling price increases on these substrates through the rest of the year.
• Higher prices, fuller factories, and better production yields should lift profit margins.

Outlook: The company expects revenue and margins to keep climbing into year-end as AI chip demand stays ahead of substrate supply.
