Which Picks-and-Shovels Names Have the Highest AI Revenue Concentration Heading Into 2027?

The AI infrastructure buildout is no longer a forecast — it is a capital expenditure reality. In February 2026, the top five US hyperscalers collectively guided to over $200 billion in 2026 capex, with the majority flowing to data center construction, power systems, networking, and semiconductors. Vertiv's backlog doubled to $15 billion. Arista raised its AI networking revenue target to $3.25 billion. Astera Labs grew revenue 115% in a single year. For investors, the question is no longer whether this spending cycle is real, but which picks-and-shovels suppliers have the most concentrated exposure to it — and which offer the best risk-reward heading into 2027.

Why This Theme Matters Now

The AI capex super-cycle has entered its acceleration phase. Hyperscaler capital budgets have roughly doubled over two years, driven by the training and inference demands of frontier AI models. Unlike prior tech spending waves, this cycle is pulling through demand across the full physical stack — power delivery, thermal management, high-speed networking, optical interconnects, and connectivity silicon. Companies with revenue directly tied to data center infrastructure are posting growth rates unseen in their respective industries, and management teams are guiding for multi-year demand visibility.

The Companies: Ranking AI Revenue Concentration

We examined five companies across the AI infrastructure supply chain — from connectivity semiconductors to power and cooling systems — to assess which have the highest share of revenue tied to AI-driven data center spending and which are best positioned heading into 2027.

1. Astera Labs (ALAB) — Pure-Play AI Connectivity Silicon

Astera Labs designs semiconductor connectivity solutions purpose-built for AI and cloud infrastructure, including PCIe retimers, smart cable modules, and switch fabric products.

Astera is the purest AI infrastructure play in this group. Virtually all of its $853 million in 2025 revenue was driven by hyperscaler data center buildouts. The Scorpio P-Series is ramping in volume, Aries PCIe 6 solutions exceeded 20% of Q3 revenue, and the company is actively developing next-generation UALink and co-packaged optics technologies. Q4 2025 revenue hit $271 million, up 92% year-over-year, with non-GAAP gross margins around 75%. Management guided Q1 2026 revenue to $286–$297 million, implying continued sequential acceleration.

Verdict: Highest AI revenue concentration in this group — near 100%. Premium valuation is justified by growth trajectory, but the stock is priced for flawless execution.

2. Arista Networks (ANET) — AI Networking at Scale

Arista is the dominant provider of high-speed Ethernet switching and routing for cloud and AI data centers, with a growing campus networking business.

Arista's AI and specialty provider segment now represents 20% of total revenue, while cloud and AI titans account for 48%. The company raised its 2026 AI networking revenue target from $2.75 billion to $3.25 billion — roughly 29% of guided $11.25 billion total revenue. Full-year 2025 revenue hit $9.0 billion, up 29%, with non-GAAP operating margins near 48%. The 800G transition is driving upgrade cycles, and 1.6T switching is emerging for 2026-2027. With $4.25 billion in trailing free cash flow and zero net debt, Arista has the balance sheet to invest aggressively.

Verdict: AI-linked revenue is large and growing fast (~30% of total, rising toward 40%), but Arista's enterprise and campus businesses dilute the pure AI concentration. Best-in-class margins and cash generation make it the quality compounder of the group.

3. Vertiv Holdings (VRT) — Power and Cooling for Every AI Rack

Vertiv designs and manufactures critical power, thermal management, and infrastructure solutions for data centers worldwide.

Vertiv is the clearest beneficiary of AI-driven data center physical buildout. Q4 2025 organic orders surged 152% year-over-year, and backlog reached $15 billion — more than double the prior year. Full-year 2025 revenue was $10.2 billion with 27% organic growth, and management guided 2026 to 28% organic growth with an adjusted operating margin of 22.5%. The company's liquid cooling solutions are increasingly critical for GPU-dense AI racks. While not all Vertiv revenue is AI-specific, management has indicated that AI and hyperscale data center demand is the primary growth driver.

Verdict: Massive order book provides multi-year visibility. AI revenue concentration is high (estimated 50-60% of incremental growth) and rising. The stock has re-rated significantly — valuation now demands continued execution on margin expansion.

4. Coherent (COHR) — Optical Interconnects Powering AI Networks

Coherent is a leading provider of optical transceivers, lasers, and photonic components used in data center interconnects and communications infrastructure.

Coherent's Datacenter and Communications segment is the primary growth engine, driven by surging demand for 800G and 1.6T optical transceivers for AI cluster networking. Q2 FY2026 (Dec 2025) revenue reached $1.69 billion, up 22% year-over-year, with data center bookings exceeding 4x revenue. The company is doubling indium phosphide production capacity by end of 2026 and secured a large co-packaged optics order. Coherent is also optimizing its portfolio — divesting non-core assets (aerospace, Munich division) to sharpen its AI-adjacent focus.

Verdict: AI revenue concentration is rising rapidly as Coherent sheds legacy businesses and doubles down on optical interconnects. The 4x book-to-bill in data center transceivers signals a multi-quarter tailwind. Portfolio complexity remains a risk.

5. Modine Manufacturing (MOD) — Data Center Thermal Specialist in Transition

Modine manufactures precision cooling solutions for data centers alongside legacy automotive and industrial thermal management products.

Modine's Climate Solutions segment is the AI story — data center sales grew 78% in Q3 FY2026, and full-year data center revenue is expected to grow over 70%. Management raised Climate Solutions growth guidance to 40-45% for fiscal 2026 and is aggressively expanding capacity. However, AI-exposed revenue is still a subset of total company sales, and the Performance Technologies segment (being divested to Gentherm for ~$210 million) has been a drag. Q3 FY2026 revenue hit $805 million, up 31%, but a noncash pension settlement loss distorted bottom-line results.

Verdict: Lowest AI revenue concentration today, but the fastest-growing AI-specific segment. The Gentherm divestiture will sharpen the data center focus. Cheapest valuation in the group on a forward P/E basis, offering the most upside if the transformation accelerates.

The Verdict: Ranking by AI Revenue Concentration

For pure AI revenue exposure heading into 2027, the ranking is clear: Astera Labs leads with near-100% of revenue tied to AI infrastructure. Arista Networks follows with roughly 30% direct AI revenue (growing toward 40%), backed by best-in-class profitability. Vertiv and Coherent are in the 40-60% range and rising fast — Vertiv through power/cooling, Coherent through optical transceivers — both with massive backlogs providing visibility. Modine has the lowest current concentration but the steepest growth trajectory in its data center segment, and its pending divestiture will meaningfully increase the AI share of the remaining business.

For investors prioritizing concentration, ALAB is the answer — but at 50x forward earnings. For those seeking a balance of AI exposure, valuation, and quality, ANET and MOD offer the most compelling risk-reward.

Risks to Watch

• Hyperscaler capex pullback: Any slowdown in cloud spending plans would hit all five names, with ALAB most exposed given its customer concentration.
• Supply chain bottlenecks: Capacity constraints in power components, optical transceivers, and advanced packaging could delay revenue recognition.
• Valuation compression: These stocks have re-rated dramatically; any disappointment in growth rates could trigger sharp corrections.

What to Monitor

• Hyperscaler capex guidance in upcoming earnings calls (Meta, Microsoft, Google, Amazon) — any upward revisions would further validate the cycle.
• Arista's AI networking revenue trajectory toward the $3.25B target; any acceleration would signal broader adoption.
• Modine's post-divestiture financials — the pure-play Climate Solutions margin profile will be the key catalyst.
