Jayshree Desai
CFO at Quanta Services
Thanks, Duke, and good morning, everyone. Quanda completed the year with 4th-quarter revenues of $6.6 billion, net income attributable to common stock of $305.1 million or $2.03 per diluted share and adjusted diluted earnings per share of $2.94. Adjusted EBITDA was $737.8 million or 11.3% of revenues. Of note, our cash-flow in the 4th-quarter and for the full-year exceeded the upper-end of our free-cash flow guidance expectations.
For the 4th-quarter and full-year of 2024, we had free-cash flow of $575.4 million and $1.6 billion, respectively, with our full-year free-cash flow a record. Our earnings and cash-flow performance allowed us to-end the 4th-quarter with ample liquidity and a balance sheet that supports both our organic growth expectations and the opportunistic investment of capital to generate incremental returns for our stockholders. To that end, subsequent to the end of 2024, we acquired two companies for aggregate upfront consideration of approximately $562 million of cash and stock.
This morning, we provided our full-year 2025 financial expectations, which calls for another year of profitable growth with record revenues, improved margins and opportunity for double-digit growth in adjusted EBITDA and adjusted earnings per share. We believe our expectations demonstrate the strength of our portfolio approach to the business, our commitment to our long-term strategy, our favorable end-market trends and our competitive position in the marketplace.
As mentioned in our earnings release, beginning with three months ending, 31 March 2025, we will report our results under two reportable segments, Electric Infrastructure Solutions and Underground utility and Infrastructure Solutions. The new Electric Infrastructure Solutions segment combines the previous Electric Power Infrastructure Solutions and Renewable Energy Infrastructure Solutions segments. This new segment reporting reflects how the business is managed and resources are allocated and better reflects the positioning of our strategies and comprehensive solutions for our growing and increasingly converging addressable markets. Additional details and commentary about our 2025 financial guidance can be found in our operational and financial commentary and outlook's expectation summary, both of which are posted on our IR website. In summary, we are executing well on our strategic plan and are pacing well against our multi-year financial targets, including double-digit EPS growth and double-digit returns. We ended 2024 with record backlog and our end-markets have never been better and we see opportunity for further strength in the coming years.
With that, we are happy to answer your questions. Operator?
