Quanta Services investment narrative recap. To own Quanta Services, you need to believe the grid build out, data center power and utility upgrade work can support a large, complex backlog without eroding execution quality. The raised 2026 revenue guidance reinforces that demand is strong. The key near term swing factor is whether this higher run rate can be delivered cleanly on large projects already in motion. The biggest risk has not really shifted. Expectations keep ratcheting up while the stock already trades on a rich P/E and carries meaningful debt. Any stumble in converting backlog into steady, high quality earnings could matter more now that guidance and investor focus sit at a higher bar. The most relevant update here is the higher 2026 revenue outlook to US$41.3b to US$41.6b, which is about US$1.9b above the prior midpoint. That move effectively locks in a tougher execution hurdle, since investors will now track whether Quanta Services can sustain recent Q3 scale across the full year without sacrificing profitability or cash conversion. This sharper revenue bar feeds directly into existing catalysts. Data center and high voltage work, transformer capacity expansion and prior acquisitions all need to keep contributing reliably to hit those numbers. If grid modernization or renewables projects slow, or integration work around deals proves bumpy, the raised guidance could shift from support to a pressure point for the stock. Quanta Services' current analyst framework points to revenues of US$54.6b and earnings of US$2.7b by 2029, based on expectations for 18.4% yearly revenue growth and an earnings increase of about US$1.4b from US$1.3b today. Uncover why Quanta Services' fair value indicates a 24% potential upside to its current price that could narrow quickly. Exploring other perspectives. One alternate view focuses on acquisition risk. Before this guidance hike, the most cautious analysts were penciling in about US$50.9b of 2029 revenue and US$2.5b of earnings, and arguing that Quanta Services might struggle to keep deal heavy growth from diluting margins. That is a much harsher story. Use it as a prompt to explore multiple narratives before you decide how this new outlook could reshape your own view.

Quanta Services keeps pushing its limits, Jefferies sees 37% upside. Records keep falling at Quanta Services. Driven by investment in power grids and data centers, the US group is blowing past expectations in the third quarter and raising its guidance once again. For Jefferies, the momentum could still deliver some pleasant surprises. Published on 10/29/2026 at 11:27 am EDT MarketScreener.com It's indeed difficult to keep up with Quanta Services. The US electrical infrastructure specialist's Q3 revenue surged 57.4%, to $12.01bn, versus $11.03bn expected by the FactSet consensus. Adjusted earnings per share soared 82%, to $6.06, exceeding analyst expectations by more than 20%. The stock was up 2.8% before the opening of Wall Street. And the growth is not based solely on acquisitions. Organic revenue rose 37.1%, while adjusted EBITDA climbed 69%, to $1.45bn. Electricity, the true growth engine The Electric Infrastructure segment, which accounts for more than 80% of revenue, posted 59% growth, to $9.8bn. Its operating margin reached 12.6%, versus 11.4% a year earlier. Investment in power grids, energy generation and technology infrastructure is running at full speed. But it is above all the business tied to major electricity-consuming facilities, particularly data centers, that is impressive. Quanta now expects revenue in this market to grow 260% to 280% in 2026, versus 220% to 240% previously. That surge, however, is being driven largely by acquisitions. This acceleration reassures Jefferies, as delays to certain data center projects observed at other players had raised fears of a sector slowdown. The bank particularly highlights Quanta's ability to select the most profitable contracts and carry out a large share of the work itself. Another encouraging signal is the order backlog, which reached a record $63.7bn, up nearly 20% in just three months. More importantly, remaining performance obligations on firm contracts rose 24%, to $41.8bn. This momentum reflects the strength of demand, beyond mere commercial intentions. Growth is also translating into cash. Free cash flow reached $1.2bn during the quarter, versus $438m a year earlier, driven in particular by better working capital management. What if the best is still to come? Buoyed by these results, Quanta is dramatically raising its ambitions for 2026. Revenue is now expected to come in between $41.3bn and $41.6bn, versus $39.3bn to $39.7bn previously. Adjusted EPS is expected to range from $17.90 to $18.30, versus the previous range of $16.45 to $16.95. According to Jefferies, nearly 97% of the increase in revenue guidance comes from the electric division alone. More interestingly, this new acceleration makes the 2027 targets less difficult to reach. The bank now estimates that adjusted EPS growth of about 13% would be sufficient to reach its forecast of $20.53 next year, versus 21% before this report. CEO Duke Austin also expects strong double-digit adjusted EPS growth in 2027. That confidence is being fueled by an investment cycle that could last several years. Jefferies therefore remains bullish on the stock, with a price target of $833, implying 37% upside from the October 28 closing price. That target nonetheless assumes the company can maintain this pace of execution, while its valuation already exceeds 33 times expected adjusted earnings for 2026. In the AI gold rush, Quanta is not looking for nuggets. It sells the shovels. (C) MarketScreener.com - 2026
