Fundamental Signals

Editor’s Note

• AI is no longer just a software story. It is a power story. We have seen the shift from “bits to atoms” for AI, and this earnings season made that tangible. The sheer magnitude of backlog tied to AI data centers, with triple-digit order growth at players like Vertiv and Eaton, signals something structural rather than cyclical. The question is no longer how big AI demand could be, but whether the grid, cooling systems, and power equipment can physically support it.

• Grid modernization and energy security are becoming non-negotiable. From GE Vernova’s accelerating electrification revenues to policy tailwinds benefiting First Solar, the sector is riding two powerful forces at once: decarbonization and reliability. With elevated risk of power supply shortfalls across large parts of the U.S., backup generation, storage, and transmission are increasingly viewed as critical infrastructure rather than discretionary spending.

• The cycle is strong, but execution risk is rising. This is clearly an Early Expansion phase, supported by record backlogs and broad-based capex. At the same time, lengthening working capital cycles, rising inventories, and tariff exposure at companies like nVent deserve attention. Over the next two quarters, I will be watching backlog conversion, margin stability, and whether inventory builds prove strategic or excessive.

Sector Earnings

The Electrical Equipment and Power Systems sector is experiencing robust growth driven by the unprecedented build-out of AI data centers, accelerating global energy transition, and critical grid modernization initiatives. However, companies navigate significant challenges including renewable energy policy volatility, softness in traditional industrial and residential markets, and the complexities of managing hyper-growth with associated working capital strains and forecasting difficulties, as revealed by recent earnings reports for the sector.

Sector / Macro Themes Driving Electrical Equipment and Power Systems

• Vertiv Holdings Co: Reported organic orders up 152% year-over-year and 117% sequentially in Q4 2025, with backlog reaching $15 billion (more than double the previous year).

Sector Cycle Read

The sector is firmly in Early Expansion. Broad-based demand, strong investment, and optimistic management tone across the majority of players signal a robust growth phase, driven by secular tailwinds. While some segments face specific headwinds, the overall momentum is positive.

Conviction & Drivers:

• Demand: Robust and broad-based, driven by secular trends in AI, Data Centers, New Energy/Electrification, Grid Modernization, and Industrial Automation. Record backlogs provide significant revenue visibility and confidence.

• Pricing: Mixed. While many companies demonstrate "price realization" and improving margins, some show margin pressure despite strong demand, indicating competitive intensity or lingering cost inflation in specific areas.

• Utilization/Capacity: High confidence, evidenced by widespread capital expenditure and capacity expansions across 12 out of 14 companies, anticipating sustained demand growth. Strategic capacity rationalization in distressed segments signals targeted bottoms.

• Inventory (DIO): Rising Days of Inventory (DIO) is a key watch item; it appears largely strategic (e.g., for anticipated demand, tariff management) but warrants close monitoring for potential oversupply or demand slowdowns.

• Working Capital: A clear trend of lengthening working capital cycles (increasing DIO/DSO for many) indicates strategic stocking or some strain on liquidity in an expansionary environment.

Cross-Section Heatmap:

Potential Long Ideas:

1. GE Vernova (Early Cycle Expansion): Exceptional order growth (↑↑) and backlog visibility, coupled with strong revenue expansion (+34%), positions it as a clear beneficiary of energy transition and early cycle strength.

2. Eaton (Early Expansion): A high-quality play with resilient margins and strong demand from hyperscale data center buildouts and grid modernization. Efficient working capital management amidst expansion is a plus.

3. Vertiv (Expansion): Pure-play exposure to the accelerating AI demand and data center infrastructure buildout, evidenced by robust orders, backlog, and improving profitability.

Catalysts & Trackers (next 1–2 qtrs):

1. Backlog Conversion & New Orders: Monitor the rate at which record backlogs (e.g., GE Vernova, nVent, Vertiv, Eaton) translate into revenue, alongside new order intake, for sustained demand proof points.

2. Gross Margin Stabilization/Improvement: Track for signs of easing cost pressures or successful pricing actions, particularly for companies currently showing mixed or declining margins (e.g., Nidec, nVent, Goldwind, Dongfang).

3. Working Capital / DIO Trends: Look for a reduction in DIO for companies that have built inventory, signaling efficient absorption by demand, or any indications of inventory liquidation.

4. AI/Data Center & New Energy Capex Announcements: Continued strong investment and project announcements from key end-market customers will reinforce the dominant secular themes.
