Jacobs Says AI Build-Out Is Now 11% of Its Net Revenue

Revenue up 35%. Net income down 24%. Both numbers are from the same quarter, and the gap between them is the most honest thing in Jacobs’ fiscal third-quarter report.

The Dallas firm reported $4.08 billion of revenue for the quarter ended June 26, up from $3.03 billion, with backlog reaching a record $28.9 billion. Net income fell to $136.6 million from $179.6 million, which the company attributes to a temporarily higher tax rate after completing its buyout of the remaining stake in London-based PA Consulting in January.

A Number Nobody Was Publishing a Year Ago

On the August 4 call, CEO Bob Pragada said direct AI build-out accounted for 11% of adjusted net revenue in the quarter, up roughly 100 basis points from the prior three months. Data center backlog has about doubled. The opportunity pipeline has tripled. Forward visibility that used to run six to nine months now stretches two to three years.

Then he hedged, and the hedge is the story: Jacobs is “being selective because there is also a lot of speculative work that’s out there.”

When a chief executive volunteers on an earnings call that a large share of his pipeline may not be real, the two-to-three-year visibility being sold is visibility into proposals. Not signed contracts. That distinction matters enormously for anyone using Jacobs’ disclosure as a proxy for how durable the AI capex cycle is.

The Rest of the Portfolio Tells You Where Headcount Is Going

CFO Venk Nathamuni said life sciences and advanced manufacturing net revenue climbed 24% year over year, the fastest growth since Jacobs began reporting by end market in late 2024. Critical infrastructure grew 9%. Water and environmental grew 1%.

One percent. That’s the segment that historically carried this firm through downturns, and it’s flat while advanced manufacturing runs at 24%. The growth is in process plants and life sciences facilities, the category that includes builds like the Ferrara Candy plant in Orangeburg County, where installation runs years past structural completion. Designers watching where their colleagues are being redeployed already know this.

Jacobs is the third major design and program management firm in as many weeks to post record backlog on the same demand, after AECOM’s $26.2 billion in late July and Granite raising guidance on a tripled data center book. Jacobs is the largest of those prints and the most explicit about concentration risk, because it’s the only one putting a named percentage on it.

For owners bidding hyperscaler and semiconductor programs, the practical consequence is that the biggest design and PM firms have started screening clients rather than chasing volume. That means less competitive tension and firmer fees on anything that looks speculative. For contractors, 11% of adjusted net revenue is now a usable benchmark for how exposed a professional-services partner is to a single capex cycle. Ask the question before you team.
