As the craze of earnings season draws to a close, here’s a look back at some of the most exciting (and some less so) results from Q1. Today, we are looking at engineering and design services stocks, starting with EMCOR (NYSE: EME).
Companies providing engineering and design services boast ever-evolving technical expertise. Compared to their counterparts who manufacture and sell physical products, these companies can also pivot faster to more trending areas due to their smaller physical asset bases. Green energy and water conservation, for example, are current themes driving incremental demand in this space. On the other hand, those providing engineering and design services are at the whim of construction and infrastructure project volumes, which tend to be cyclical and can be impacted heavily by economic factors such as interest rates.
The 5 engineering and design services stocks we track reported a very strong Q1. As a group, revenues beat analysts’ consensus estimates by 1.7% while next quarter’s revenue guidance was in line.
Luckily, engineering and design services stocks have performed well with share prices up 14.1% on average since the latest earnings results.

Market Update
The Fed’s interest rate hikes throughout 2022 and 2023 have successfully cooled post-pandemic inflation, bringing it closer to the 2% target. Inflationary pressures have eased without tipping the economy into a recession, suggesting a soft landing. This stability, paired with recent rate cuts (0.5% in September 2024 and 0.25% in November 2024), fueled a strong year for the stock market in 2024. The markets surged further after Donald Trump’s presidential victory in November, with major indices reaching record highs in the days following the election. Still, questions remain about the direction of economic policy, as potential tariffs and corporate tax changes add uncertainty for 2025.
