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 Q4. Today, we are looking at construction and maintenance services stocks, starting with Limbach (NASDAQ: LMB).

Construction and maintenance services companies not only boast technical know-how in specialized areas but also may hold special licenses and permits. Those who work in more regulated areas can enjoy more predictable revenue streams - for example, fire escapes need to be inspected every five years. More recently, services to address energy efficiency and labor availability are also creating incremental demand. But like the broader industrials sector, construction and maintenance services companies are at the whim of economic cycles as external factors like interest rates can greatly impact the new construction that drives incremental demand for these companies’ offerings.

The 12 construction and maintenance services stocks we track reported a strong Q4. As a group, revenues beat analysts’ consensus estimates by 4.7% while next quarter’s revenue guidance was 0.7% above.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 10.5% since the latest earnings results.
