Yuanta rates SMT a Buy with 7.60 baht target, sees Optical-AI driving 70% profit growth in 2027

KLA Corporation is benefiting from accelerating artificial intelligence infrastructure spending, which is driving higher investments in leading-edge foundry and logic technologies and boosting demand for its process-control solutions. In fiscal 2026, the Semiconductor Process Control segment's revenues increased 12% year over year, and overall fiscal 2026 revenues rose 12% year over year to $13.58 billion. During the fourth quarter of fiscal 2026, management raised its calendar 2026 wafer-fabrication equipment market estimate, including advanced packaging, to the low-$150 billion range, up from its previous $140 billion-plus view and approximately $120 billion in calendar 2025. KLAC expects second-half 2026 revenues to be approximately 20% higher than the first half, aided by high-performance computing, high-bandwidth memory, increasing extreme ultraviolet adoption in DRAM and advanced packaging technologies such as hybrid bonding, and said backlog was expected to reach about $12.5 billion. The company faces intensifying competition from Applied Materials, which expects its process diagnostics and control business to grow more than 50% in calendar 2026, and from ASML, which expects advanced foundry and logic revenues to rise about 25% in 2026 and extreme ultraviolet revenues to increase roughly 45%.

Amazon Web Services posted $42.23 billion in revenue, growing 37% year over year, the segment's fastest growth in 18 quarters, with a 39.4% operating margin and a $496 billion contracted backlog. Amazon's chips and AI businesses each eclipsed run rates of more than $25 billion in the second quarter, both growing at triple-digit percentages year over year, while 98% of Amazon's top 1,000 EC2 customers use Graviton and Anthropic and OpenAI have made multi-year, multi-gigawatt commitments to Trainium. Q2 operating income landed at $27.46 billion, up 43.2% year over year, and advertising is a $70 billion-plus trailing-twelve-month business growing 26%. Capex reached $54.21 billion in a single quarter, up 68.4% year over year, and free cash flow swung to negative $7.6 billion on a trailing-twelve-month basis, though most AI capacity is contracted for at least five-year terms. Since Amazon reported Q2 on July 30, 2026, AMZN moved from $230.08 to $251.19, while SPY went from $747.03 to $762.70 and QQQ went from $687.99 to $716.92. Andy Jassy said AWS could become a few hundred billion dollar revenue business and now believes it will be at least double that and very possibly a trillion dollar annual revenue business in time.

Micron Technology is trading at roughly 6x forward earnings against a consensus analyst price target of $1,513.11, implying about 59% upside from its current $953.49 share price. The Boise-based memory maker, the only U.S.-headquartered producer of DRAM and NAND at scale, has signed 16 multi-year take-or-pay contracts covering roughly 25% of revenue, backed by $22 billion in cash deposits and letters of credit, with remaining performance obligations near $100 billion. CEO Sanjay Mehrotra said AI has elevated the value of memory, and management expects high-bandwidth memory supply tightness to persist beyond calendar 2027, with data-center DRAM and NAND bit shipments projected to more than double from two years ago. Micron has already shipped over $1 billion in HBM4 revenue, with the 12-high volume ramp tracking twice as fast as HBM3E 12-high, and fiscal fourth-quarter guidance calls for record revenue of $50 billion plus or minus $1 billion and non-GAAP earnings per share of $31 plus or minus $1 at a gross margin near 86%. The stock is up 234.28% year-to-date and 501.33% over the past year, and beginning December 9, 2026, Micron plans to increase capital returns and eventually return 100% of excess cash to shareholders.
