Quarterly Highlights
Explosive growth in the E-Infrastructure segment drove a massive jump in overall performance.
Record Revenue and Earnings: Consolidated revenue for the quarter reached $1.564B, up 127% YoY, with organic growth at approximately 70%; Adjusted Diluted EPS (Non-GAAP) reached $7.58, up 118% YoY; Adjusted EBITDA reached $337.8M, up 117% YoY. Full-year expectations were significantly revised upward, with the median full-year Adjusted Diluted EPS forecast at $21.83, approximately 7.5% higher than the upper end of the previous guidance.
Triple-Digit Growth in E-Infrastructure: E-Infrastructure Solutions revenue reached $1.303B this quarter, up 212% YoY, driven by triple demand from data centers, semiconductor fabs, and advanced manufacturing parks. Adjusted Operating Income reached $302.4M, up 171% YoY, with an Adjusted Operating Margin of 23.2%. Site development business organic growth more than doubled, with strong growth across all regions.
Rapid Expansion of CEC Electrical Business: CEC's quarterly revenue reached $426M, growing more than fourfold compared to the same pro-forma quarter last year; cumulative revenue for the first three quarters has exceeded $800M, and management expects the full year to surpass $1B, far exceeding initial expectations at the time of acquisition. CEO Joe Cutillo noted that the Adjusted Margin for CEC's core business has improved by over 150 basis points since the acquisition, ahead of the original schedule.
Total Backlog Approaching $8B, Visibility Greatly Enhanced: As of late September 2026, total backlog (including $4.1B in contracted backlog, $2.0B in awarded but not yet contracted projects, and approximately $1.7B in next-phase design work) approached $8B, a YoY increase of about 90%. Management also noted that existing customer campuses have thousands of acres of permitted land with secured power, representing over five years of additional development potential not included in the figures above.
Transportation Solutions Resource Reallocation, Record Margins: Transportation Solutions revenue was $165.2M, down 3% YoY, as the company proactively shifted labor and equipment to higher-margin E-Infrastructure projects. Despite this, Adjusted Operating Income rose 22% YoY, and the Adjusted Operating Margin reached 19.7%, reflecting disciplined project selection.
Strong Cash Flow, Balance Sheet Shifts to Net Cash: Cash flow from operations for the first three quarters reached $427M, up 68% YoY. Quarter-end cash was $217M against only $95M in debt, resulting in a net cash position of $122M. In July, the credit facility was expanded to $15B and extended to 2031; $107M in shares have been repurchased year-to-date, with $267M remaining under authorization.
Early Positioning in Semiconductor Market, Replicating Data Center Success: The company's execution on a large semiconductor fab project in New York is several months ahead of schedule, leading to an invitation to handle Micron's fab construction in Idaho. This successfully replicates the company's data center execution reputation in the semiconductor market. CEO Joe Cutillo stated that the semiconductor construction wave is expected to accelerate around 2030, and the company's early positioning will make it the preferred partner for large-scale semiconductor projects.
