Three companies that supply the physical backbone of artificial intelligence all raised their 2026 financial guidance in late July, and all three are sitting on record order backlogs. Vertiv Holdings (NYSE:VRT), Equinix (NASDAQ:EQIX), and Digital Realty Trust (NYSE:DLR) cover the three layers of AI infrastructure that matter after the chips are designed: power and cooling, interconnection, and the buildings that house it all.
Vertiv is the equipment maker. It sells power trains, thermal management systems, UPS units, switchgear, and is working on 800-volt DC architectures being validated for next-generation NVIDIA racks. The stock closed at $261.95 on August 21, giving it a market cap of roughly $100.85 billion. Shares are up 107.17% over the past year and 61.76% year to date, though they have cooled 13.02% over the past month.
Vertiv's numbers back the thesis
Vertiv's Q2 2026 results gave the bull case hard numbers. The company delivered net sales of $3.274 billion, up 24% year over year, with adjusted EPS of $1.52 and adjusted operating margin of 22.6%, up 410 basis points. Management raised full-year sales guidance to roughly $14 billion at the midpoint with adjusted EPS of $6.65 to $6.75.
CEO Giordano Albertazzi described a pipeline spanning hyperscalers, enterprises, colocation, and neocloud customers. His assessment was direct: "This is real, this is happening." Analyst sentiment sits at 86% bullish and 0% bearish, with an average target of $338.15 and a forward P/E of 41. The stock trades like a growth compounder tied to a decade-long AI infrastructure cycle.
The risk to watch is geographic. EMEA organic growth was only 2% in Q2, and the stock's 2.08 beta means drawdowns will be sharp when AI sentiment wavers.
Equinix owns the interconnection layer
Equinix is the connectivity layer. If Vertiv sells the gear, Equinix owns the neutral meeting rooms where clouds, networks, and AI model providers cross-connect. Shares closed at $1,065.39, up 41.15% year to date, with a market cap near $105.12 billion.
The interconnection flywheel is accelerating. In Q2 2026, Equinix added 9,700 net interconnections, its highest-ever quarterly addition, and posted annualized gross bookings of $424 million, up 23% year over year. Revenue grew 16% year over year with adjusted EBITDA margin of 53%. Management said that "Eight of the top 10 model providers, as well as eight of the top 10 neoclouds, are already running their key networking workloads on Equinix today."
Full-year revenue guidance was raised to 11% to 12% growth, and the 2027 to 2029 outlook now calls for 10% to 13% annual revenue growth with adjusted EBITDA margin of 53% or higher by 2029. Analyst sentiment sits at 81% bullish, 0% bearish, with a 1.82% dividend yield and forward P/E of 61.
The caveat: raised capex guidance of $5 billion to $6 billion in 2026 and $5 billion to $7 billion annually through 2029 pressures near-term free cash flow. Neocloud competition is a real overhang.
Digital Realty is the hyperscale landlord
Digital Realty Trust is the wholesale REIT that owns the megawatts hyperscalers are leasing years in advance. Shares closed at $190.62, up 24.87% year to date, with a market cap of $71.81 billion and an indicated annual dividend of $4.89 for a 2.51% yield.
Q2 2026 showcased the scale of AI demand hitting hyperscale property owners. Digital Realty reported a record $1.9 billion backlog at 100% share, a development pipeline that expanded to 1.4 gigawatts under construction at a total cost of $20 billion, and renewals with cash releasing spreads over 25%. Just after quarter end, two additional US hyperscale leases added $410 million of annualized GAAP rent at 100% share.
CEO Andy Power said, "Strong operating performance, a record backlog, and healthy customer demand give us increasing confidence in our ability to deliver double-digit earnings growth in 2027 and beyond." Analyst sentiment stands at 79% bullish, 0% bearish.
The risks are REIT-specific: interest rate sensitivity, $1.2 billion in cash plus 12.3 million shares issued for the Blackstone Northern Virginia acquisition, and a -58.7% year-over-year earnings comp reflecting REIT accounting noise around gains and development timing.
Why this matters for real estate and construction professionals
For anyone building or managing data center assets, these three companies show where AI capex actually lands: power, connectivity, and real estate. Digital Realty's 1.4 gigawatts under construction at a total cost of $20 billion is a direct signal about construction demand. Vertiv's 800-volt DC work affects how data centers are designed, not just equipped. And Equinix's record interconnection additions suggest that network-dense facilities - not just raw megawatts - are where the value is concentrating.
For professionals tracking this sector, the relevant question isn't whether AI infrastructure spending is real. All three companies raised guidance on record demand. The question is how the construction pipeline, power delivery systems, and interconnection capacity get built out over the next several years. Those with exposure to data center construction, electrical systems, or cooling infrastructure are working in one of the few sectors where customers are signing leases and committing capital years in advance. Professionals looking to understand how AI is reshaping this sector can find relevant training through AI for Real Estate & Construction courses, or for those in leadership roles, AI for Executives & Strategy programs.
