Can EMCOR Maintain Its 9.1% Margin Streak as Data Centers Explode?
Read MoreHide Full Article
Key Takeaways
EME is benefiting from surging data center demand, with networking RPOs reaching $4.3B as of September 2025.
EMCOR posted a 9.1% operating margin in the first nine months, driven by execution and project discipline.
Management raised full-year margin guidance to 9.2-9.4% as scale and complexity continue to rise.
EMCOR Group, Inc. (EME - Free Report) is gaining from the strength witnessed across the network and communications sector, mainly driven by increased data center construction project momentum. The company is increasingly serving data-center customers across electrical, mechanical and fire-life safety scopes, allowing it to capture greater wallet share per site while spreading fixed overhead more efficiently. As of Sept. 30, 2025, Remaining Performance Obligations (RPOs) were $12.61 billion, indicating 29% year-over-year growth, with the networking and communications sector contributing about $4.3 billion to the value.
Owing to strong execution, disciplined project selection and a surge in data-center demand that is reshaping its backlog and revenue mix, EMCOR posted 9.1% of operating margin during the first nine months of 2025, with 9.4% reported in the third quarter. For 2025, EME now expects operating margin in the range of 9.2-9.4% compared with the previous expectation of 9-9.4%.
Notably, margin durability, however, depends less on demand and more on execution. EME continues to leverage prefabrication, Virtual Design and Construction (VDC) and Building Information Modeling (BIM) to keep labor hours growing far slower than revenues, while maintaining pricing discipline through careful contract negotiation and project mix management.
Investments in new geographies, workforce ramp-ups and backlog amortization from acquisitions such as Miller Electric and John W. Danforth can create short-term headwinds. However, in the long term, these investments are designed to build long-term scale and productivity in high-growth markets. Summing up, exploding data-center demand is not diluting EMCOR’s margin profile; rather, it is testing it. So far, execution suggests EMCOR is passing that test, though sustaining 9.1% will require continued discipline as scale and complexity increase.
