2340 GMT - As TSMC expands its global manufacturing footprint to secure future AI chip supply chains, its overseas hubs are emerging as new profit drivers, according to the company's latest filings. TSMC Arizona, once viewed as a costly overseas venture with uncertain returns, generated 36 billion New Taiwan dollars in net profit during 1H of 2026, more than doubling its full-year 2025 net profit. Its joint venture in Japan swung from a NT$9.77 billion full-year loss in 2025 to a NT$1.68 billion net profit in the first half. TSMC Nanjing also remained steadily profitable. The results suggest that TSMC can replicate its industry-leading profitability beyond Taiwan, analysts say.
