Summary
Summary of the 8-K filed October 30, 2025. Cited figures are marked; the original filing is the authoritative source.
Quanta Services (PWR) reported third-quarter 2025 results on October 30, 2025, with revenue of $7.63 billiona, up about 18% from $6.49 billion a year earlier, and GAAP diluted EPS of $2.24 versus $1.95.
Adjusted diluted EPS rose to $3.33b from $2.72, roughly 22% growth. Adjusted EBITDA reached a record $858.3 million, and net income attributable to common stock was $339.4 million. Growth was led by the Electric segment, whose revenue rose about 18% to $6.17 billion and whose operating margin expanded to 11.4%.
Total backlog reached a record $39.2 billionc and remaining performance obligations reached $21.0 billion, supporting management's view of record backlog and double-digit EPS growth in 2026. The filing also announced that NiSource selected Quanta to provide design, procurement and construction services for generation and grid infrastructure capable of about 3 gigawatts of power for a large load customer, through a 50%-owned joint venture with Zachry Group. Management stated that the project is not meaningfully reflected in current backlog, with execution expected to start in 2026 and full completion by 2032.
This signals an expansion of Quanta's addressable market into gas-fired generation, a notable strategic move. The filing did not include updated full-year guidance in the exhibits; management stated it would post updated 2025 guidance separately on its website.
The estimated full-year 2025 ranges carried in the non-GAAP reconciliations imply adjusted diluted EPS of $10.33 to $10.83d and free cash flow of $1.3 billion to $1.7 billion. Free cash flow was weaker year-to-date at $726.3 million, with operating cash flow of $1.1 billion and net capital expenditures of $376.1 million.

03—Questions
Frequently Asked Questions
What drove Quanta's growth in the third quarter of 2025?
Growth was driven mainly by the Electric segment, where revenue rose about 18% to $6.17 billion and operating income rose to $703.8 million. Management attributed this to accelerating demand in the Electric segment, with contributions from acquisitions including Dynamic Systems in the Underground and Infrastructure segment.
Does the NiSource project materially affect current backlog or near-term earnings?
Not significantly yet. The company said backlog at quarter-end did not include a meaningful contribution from the project. The scope and estimation phase has begun, execution is expected to start in 2026 after regulatory approvals, and revenue is expected to be recognized over multiple quarters through 2032, mostly within the Electric segment.
Did Quanta update its full-year 2025 guidance?
The filing did not contain new formal guidance in the exhibits. Management said it would post an updated 2025 outlook with commentary on its website before the call. The non-GAAP reconciliations in the release show estimated 2025 GAAP diluted EPS of $6.53 to $7.02, adjusted diluted EPS of $10.33 to $10.83, and free cash flow of $1.3 billion to $1.7 billion.
Are there concerns about cash flow or balance sheet trends?
Yes, some. Year-to-date operating cash flow fell to $1.10 billion from $1.37 billion, and free cash flow fell to $726.3 million from $979.3 million. Receivables and contract assets grew substantially, and long-term debt increased to $5.53 billion from $4.10 billion, largely reflecting acquisitions and working capital needs. Investors should watch whether cash conversion recovers in the fourth quarter.
What did Quanta say about capital allocation?
Year to date, Quanta repurchased about 538,600 shares for $134.6 million, leaving approximately $365.1 million under its repurchase authorization as of October 29, 2025. It also completed five acquisitions in the first nine months of 2025, including Dynamic Systems in the third quarter.
