3,800 MW of contracted nuclear power for AI data centers — double the nearest competitor. Deregulated market means they sign direct long-term contracts with hyperscalers at real market prices. Meta: 2 GW, 20-year deal. Amazon: 1.2 GW, 20 years. When gas prices rise, nuclear's fixed cost structure means Vistra's margin expands while everyone else's shrinks. Revenue grew 13% last year; guiding 22% EBITDA growth in 2026. PEG ratio: 1.3.

3800兆瓦签约核电供AI数据中心——是最近对手的两倍。自由市场意味着可以与超算商签直接长期合同。Meta：2吉瓦20年。Amazon：1.2吉瓦20年。天然气涨价时，核电的固定成本结构意味着Vistra利润率扩大，而其他人的在缩。营收去年增长13%；2026年指引EBITDA增长22%。PEG比率：1.3。

Transformer lead times: 128–144 weeks — nearly 3 years. Half of planned US data center builds in 2026 are delayed or canceled because of this alone. Eaton owns the full chain: transformers, switchgear, power distribution units, busway — the only company end-to-end. They capture $3.4M per MW of installed data center capacity. Current backlog represents 11 years of installed capacity at 2025 build rates. EPS nearly doubled in 4 years. Operating margin: 14% → 19%, targeting 30% in data center segment for 2026.

变压器交付周期：128–144周——近3年。2026年美国一半计划中的数据中心因变压器延迟或取消。Eaton拥有完整链条：变压器、开关设备、配电单元、母线——唯一端到端的公司。每兆瓦装机容量获340万美元收入。当前积压订单相当于2025年建设速率下11年的产能。4年内EPS近翻倍。运营利润率从14%升至19%，数据中心板块2026年目标30%。

Nvidia's latest AI racks pull 132 kW — nearly 10× a traditional server's 10–15 kW. Air cooling can't handle it. Vertiv owns UPS systems, power distribution, and liquid cooling as one integrated system — the only major player with all three under one roof in 2026. Nvidia named them their preferred infrastructure provider for AI factories globally. EPS grew 199% last year. Guiding 30% revenue growth in 2026. Entered 2026 with $15B committed backlog — more than a full year of revenue already signed.

英伟达最新AI机架功耗132千瓦——传统服务器的近10倍。风冷无法应对。Vertiv拥有UPS、配电和液冷一体化系统——2026年唯一同时拥有三者的主要玩家。英伟达指定为全球AI工厂首选基础设施供应商。EPS去年增长199%。2026年指引营收增长30%。以150亿美元承诺积压订单进入2026年——已超过全年营收。

Every HBM supplier on the planet is sold out through 2026, with waitlists into 2027. Micron holds 21% of global HBM supply — and they're the only major player with US fabs and domestic helium access. When Korean input costs rise, Micron either gains market share (SK Hynix produces less) or the whole market's price expands. Revenue grew 56% last year; EPS expanded 175%. PEG ratio: 0.25 — the lowest on this list by far.

全球所有HBM供应商2026年全部售罄，候补名单排到2027年。美光占全球HBM供应的21%——唯一拥有美国晶圆厂和国内氦气来源的主要玩家。韩国投入成本上升时，美光要么抢占份额，要么全市场价格上升。营收去年增长56%；EPS增长175%。PEG比率：0.25——本清单中最低。

CoWoS demand growing 80% YoY — supply only at 50%. The gap won't close in 2026. Nvidia controls over half of TSMC's CoWoS capacity, meaning every other AI chipmaker (Broadcom, AMD, custom ASICs) needs a second source. Amkor is that second source. Their Arizona facility sits directly adjacent to TSMC's US fabs, funded in part by the CHIPS Act. Advanced packaging business expected to nearly triple this year as overflow demand falls into their lap.

CoWoS需求增长80%——供应仅50%。缺口2026年不会闭合。英伟达控制台积电CoWoS产能的一半以上，意味着其他所有AI芯片制造商都需要第二来源。Amkor就是那个第二来源。亚利桑那工厂紧邻台积电美国工厂，部分由CHIPS法案资助。先进封装业务预计今年近翻三倍。

Entered 2026 with $73 billion in signed AI orders — 18–24 months of committed revenue before the year started. Two pieces of the networking layer: custom AI accelerators (Google's TPU, Meta's MTIA, Amazon's Trainium — all co-designed with Broadcom, 60–70% custom AI chip market share) and Ethernet switching (Tomahawk 6 controls 80% of Open Ethernet). AI went from footnote to $8B last quarter — 43% of total revenue. Guidance already up 27% for the next quarter.

以730亿美元签约AI订单进入2026年——年初就锁定18-24个月营收。网络层的两块：定制AI加速器（Google TPU、Meta MTIA、Amazon Trainium——均与博通联合设计，60-70%定制AI芯片市场份额）和以太网交换（Tomahawk 6控制80%开放以太网市场）。AI从注脚变为上季度80亿美元——占总营收43%。下季度指引已上调27%。

63 million 800G+ optical transceivers shipping this year — a 2.6× jump from last year — with a Marvell chip inside every one. The optical DSP converts electrical signals to light pulses for fiber. Market is a duopoly (Marvell #1, Broadcom #2). At 224 Gbps, copper reaches less than 1 meter and consumes 30% of the cluster's power. Optical cuts that by 70%. The data center industry doesn't have a choice — they have to switch. EPS tripled in a single year on a segment that barely existed when the Inphi acquisition closed.

6300万个800G+光收发器今年出货——比去年增长2.6倍——每个里面都有迈威尔芯片。光DSP将电信号转换为光纤中的光脉冲。市场是双寡头（迈威尔第一，博通第二）。224 Gbps下，铜线传输不到1米且消耗集群30%的功耗。光传输降低70%。数据中心没有选择——必须切换。EPS在Inphi收购后一个业务几乎不存在的细分市场一年内翻三倍。

27–33 tons of copper per megawatt of installed data center capacity. A single 100 MW hyperscale facility consumes more copper than most mid-sized city infrastructure projects combined. Copper is inside everything that's not silicon — power distribution, cooling loops, transformers, bus bars. S&P Global projects a 330,000 ton deficit in 2026, widening to a 10 million ton shortfall by 2040. Southern Copper: largest reserve base of any publicly listed miner (51.1M tons), producing at 42¢/lb net cash cost — five times cheaper than competitors. Revenue nearly doubled over 5 years; 52% operating margin.

每兆瓦数据中心装机容量需要27–33吨铜。单个100兆瓦超算商设施消耗的铜超过大多数中等城市基建项目的总和。铜在所有非硅的东西里——配电、冷却回路、变压器、母线。S&P Global预测2026年33万吨铜缺口，到2040年扩大到1000万吨。南方铜业：公开上市矿企中最大储量基础（5110万吨），生产成本每磅42美分——比竞争对手便宜5倍。5年营收近翻倍；52%运营利润率。

AI data centers require 36× more fiber than a traditional server rack. Lead times on ribbon fiber: 60+ weeks. Corning makes the optical fiber cable connecting every server, switch, and GPU cluster — and every one of those 63M transceivers requires fiber. Operates the world's largest fiber cable plant (Hickory, NC). Meta signed a multi-year deal worth up to $6B in January. Demand growing 22–25% annually; supply can only expand 11–19%. New preform capacity takes 18–24 months to come online. Operating income doubled in a single year. Hyperscaler optical segment grew 61%.

AI数据中心需要36倍于传统机架的光纤。带状光纤交付周期：60周以上。康宁制造连接每台服务器、交换机和GPU集群的光缆——6300万个收发器每个都需要光纤。运营全球最大光纤工厂（北卡Hickory）。Meta 1月签署最高60亿美元多年协议。需求年增22-25%；供应仅能扩张11-19%。新预制棒产能需18-24个月上线。运营收入一年翻倍。超算商光学业务增长61%。

Vistra, Eaton, Vertiv. Lower volatility, steady compounding. The demand story doesn't depend on any one company winning the chip wars. Nothing in AI works without power and cooling.

Vistra、Eaton、Vertiv。较低波动，稳定复利。需求故事不依赖任何一家公司赢得芯片战争。没有电力和散热，AI什么都做不了。

Micron, Amkor, Broadcom, Marvell. Highest upside over the next 5 years. The photonics transition is just beginning. Custom silicon is accelerating. HBM demand has no ceiling in sight. Marvell and Broadcom are the conviction positions inside this group.

美光、Amkor、博通、迈威尔。未来5年最高上行空间。光子转型刚刚开始。定制芯片加速。HBM需求没有天花板。迈威尔和博通是这一组的信念仓位。

Southern Copper and Corning. Supply deficits are real and don't resolve quickly. Longer time horizons, more value-oriented plays. The choke points are structural — they can't be engineered around.

南方铜业和康宁。供应缺口真实且不会快速解决。更长周期，更偏价值型。瓶颈是结构性的——无法通过工程设计绕过。
