Sterling's Electrical Capacity Gets Tight: Can M&A Bridge the Gap?
Sterling Infrastructure, Inc. STRL is facing a constraint in its fast-growing E-Infrastructure business as electrical demand is testing available capacity. The company’s CEC electrical operation has expanded far faster than initially expected, supported by strong data-center activity and growing cross-selling opportunities with Sterling’s site-development business. In the second quarter of 2026, CEC revenues increased 140% year over year, while E-Infrastructure revenues surged 192%.
The capacity squeeze is particularly evident in the electrical workforce. Management said CEC’s available capacity, which Sterling originally expected to fill over roughly a year following the acquisition, was filled in about 90 days. CEO Joe Cutillo added that CEC could be growing even faster if Sterling had another 1,000 to 2,000 electricians. The company is investing in recruiting, training and prefabrication facilities, but opportunities for joint electrical and site-development work currently exceed its electrical capacity.
That imbalance strengthens the case for acquisitions. Management said Sterling will need more acquisitions to add capacity and keep pace with anticipated demand, while also pursuing geographic expansion. The company is targeting small-to-mid-sized acquisitions that can expand capabilities, geographic reach, customer relationships or capacity. Sterling also has financial flexibility to pursue this strategy. It ended June with $464 million of cash and $284 million of debt, resulting in a $181 million net cash position. Its revolving credit facility was subsequently expanded to $1.5 billion and extended through July 2031, providing additional dry powder for acquisitions.
The opportunity remains substantial. E-Infrastructure backlog, unsigned electrical awards and future-phase opportunities topped $6 billion, with mission-critical work representing more than 92% of signed E-Infrastructure backlog. Sterling’s key challenge is adding enough capacity to capture this demand, making M&A an important lever for adding talent, expanding geographic reach and sustaining growth.
M&A and Labor Capacity Intensify Infrastructure Competition
Sterling’s acquisition-led expansion of electrical capacity reflects a broader industry push to scale skilled labor and technical capabilities for data centers and mission-critical projects. Competitors such as EMCOR Group, Inc. EME and Quanta Services, Inc. PWR are also expanding through acquisitions and workforce investments.
EMCOR continues to expand its electrical platform through targeted acquisitions. In the second quarter, the company highlighted five electrical businesses that collectively generated about $625 million of trailing-12-month revenues and $105 million of EBITDA. The deals expand EMCOR’s geographic reach and technical capabilities, particularly in Texas, Wisconsin, Ohio, Florida and the Chicago area, while creating opportunities to pivot acquired contractors toward data-center work.
Quanta is similarly expanding its craft-skilled capacity through organic hiring and acquisitions. Its recent purchases of Phalcon, Enerfab, Percheron and PSD strengthen electrical, mechanical, civil and fabrication capabilities and broaden its geographic reach. Quanta said it self-performs 80-85% of its work and added more than 15,000 employees over the past year, including more than 7,000 organically, while investing roughly $250 million annually in training.
