Goldman Sachs has identified nine stocks in Japan's electronic components and semiconductor space that it rates as potential beneficiaries of stronger demand for AI and data center equipment. The investment bank's analysis focuses on catalysts such as earnings revisions, capacity additions and rising operating margins across a range of suppliers.
Top-ranked companies and the near-term catalysts Goldman Sachs highlighted
1. Ibiden - Buy
The bank expects Ibiden to lift its medium-term financial plan and to disclose additional capacity expansion. Management has already revised electronics division operating margin guidance from 22.7% to 29.3% for the full year, with the change attributed mainly to selling price improvements. Goldman Sachs also noted that for CPUs the operating margin for Ibiden's largest customer could move from just under 20% in the first quarter to nearly 30% by the fourth quarter. The medium-term targets - operating profits of yen150 billion in fiscal 2028 and yen300 billion or more in fiscal 2031 - could be revised upward when Ibiden reports second-quarter results. Ibiden reported first-quarter fiscal 2026 revenue and earnings above analyst expectations and lifted its full-year outlook, citing robust demand for AI server substrates.
2. Murata Manufacturing - Buy
Goldman Sachs expects upside to Murata's second-quarter earnings and further upward revisions to full-year guidance. The bank highlighted a multilayer ceramic capacitor (MLCC) book-to-bill ratio of 1.47x in the first quarter, suggesting second-quarter assumptions may be conservative. Murata revised annual sales growth for MLCCs used in AI and data centers from 85-90% to 100-105%. Management has increasingly signaled openness to partial price increases as market conditions permit.
3. Taiyo Yuden - Buy
Goldman Sachs sees Taiyo Yuden moving into a period of rapid earnings recovery in the second and third quarters. The MLCC book-to-bill ratio reached 1.72x and utilization rose from about 85% in the first quarter to roughly 95% in the second. Sales growth for AI server products was revised from 80-85% to 150%. While Taiyo Yuden's first-quarter operating profit fell short of consensus, the company raised its full-year operating profit guidance to a level above forecasts.
4. Renesas - Buy
The bank expects near-term quarterly earnings expansion and improved profitability in fiscal 2027 tied to in-house capacity expansion. Renesas's data center sales are projected to exceed yen300 billion in fiscal 2026, representing an 85-90% year-over-year increase from slightly over yen160 billion in fiscal 2025.
5. Rohm - Buy
Goldman Sachs flagged the potential for a material full-year upward revision at Rohm. Second-quarter earnings could be supported by sales growth, underpinned by a first-quarter book-to-bill ratio of 1.2x and rising utilization rates that Goldman Sachs expects to move toward 70% or higher by September. Fiscal year 2027 sales guidance for AI and data center products was increased from yen25.0 billion to yen30.0 billion.
6. TDK - Buy
TDK is another candidate for a meaningful full-year upward revision, according to Goldman Sachs. First-quarter results and outlook across TDK's businesses beat expectations, and second-quarter operating profit could exceed yen100 billion. Annual sales guidance for industrial batteries was raised from roughly yen110 billion to roughly yen150 billion, with most of the increase tied to uninterruptible power supply (UPS) batteries for AI and data center applications.
7. Kyocera - Buy
Goldman Sachs expects Kyocera to provide news on further upside to fiscal 2027 guidance, primarily driven by AI and data center related components. The bank also noted the possibility of an upward revision to Kyocera's return-on-equity target in the company's next medium-term plan.
8. MinebeaMitsumi - Buy
For MinebeaMitsumi, the bank is watching for upside potential to fiscal 2027 guidance driven mainly by bearings and motors, along with clearer visibility on the company's ability to hit its medium-term plan.
9. Nidec - Buy
Goldman Sachs's primary near-term focus for Nidec is the status of the company's securities report filing, which is due on September 30.
Context and common themes
The firm points to several recurring themes across these names: strong end-market demand tied to AI and data center buildouts, book-to-bill ratios above parity for several MLCC suppliers, rising utilization rates as capacity comes back online, and managements that have either already raised guidance or signaled they may do so. Where applicable, Goldman Sachs highlighted specific margin improvements and the potential for companies to lift medium-term targets or provide capacity expansion updates at upcoming results announcements.
Investment implications
Goldman Sachs's list concentrates on component and semiconductor suppliers where the bank sees measurable improvements in demand indicators, operating leverage and pricing dynamics. The identified catalysts - earnings upgrades, capacity additions and margin expansion - are company-specific but reflect broader strength in AI and data center spending that could influence supplier earnings over the next several quarters.
