TSMC's AI growth still faces margin pressure from overseas fab expansion and a faster A14 ramp for mobile customers facing 2nm SoC challenges. 3Q gross margin of 66.4% missed expectations, and the 4Q guide is softer at 65-67%; margins are expected to remain largely flat through 2027-28 despite projected 39% revenue growth in 2027. Hold; target nudged to NT$2,999 at 20x 2027 earnings. x.com x.com x.comÂ
