Quanta Services' Backlog Hits Record $48.5 Billion on AI Infrastructure Demand

Citi says growing political opposition to artificial intelligence infrastructure ahead of the November U.S. midterm elections has not materially weakened the data center construction pipeline. Data center development has become a bipartisan flashpoint, with local governments introducing moratoriums and at least 15 state legislatures proposing tighter regulatory restrictions, yet spending remains strong as AI infrastructure demand continues to support development. The impact has been concentrated among speculative and early-stage projects, which are increasingly delayed or cancelled during local approval processes, while late-stage developments that have already secured sites and grid connections continue to move ahead. Hyperscalers are seeking workarounds to power constraints and local restrictions, with Amazon pursuing direct investment in nuclear development with Dominion Energy and Meta securing a major nuclear power purchase agreement with Constellation Energy. Citi does not expect another market shock comparable to the emergence of DeepSeek, arguing investors have already adjusted to the prospect of highly efficient Chinese models, though it flags a potentially greater risk from governments restricting models deemed too dangerous, which could abruptly create excess computing capacity.

Caterpillar announced on September 15 that its self-driving haul trucks at a Luck Stone quarry are moving large tonnage, with expansion to two more Virginia quarries, Boscobel and Bealeton, including the first autonomous deployment of Cat 775 trucks. The company disclosed no order value, truck count, or profit contribution from the autonomy milestone, and autonomy was named on the earnings call only as a source of higher SG&A and R&D expenses inside Resource Industries. In the second quarter of 2026, revenue reached $20.5 billion, up 24% year over year, with adjusted EPS of $8.17, up 73%, while backlog climbed to $72 billion, up roughly $35 billion versus a year earlier. Power & Energy is the engine, with segment sales up 17% to $8.2 billion and power generation sales up 72% on large gensets and turbines for data centers, and gas prime orders extend toward the back half of 2028 and into 2029. Caterpillar trades at $798.51 against a consensus analyst target of $975.61, a trailing PE of 34x, and full-year tariff costs of around $2.2 billion for 2026, with expected IEEPA tariff recoveries of approximately $400 million.
