Let’s dig into the relative performance of ABM (NYSE: ABM) and its peers as we unravel the now-completed Q4 industrial & environmental services earnings season.

Growing regulatory pressure on environmental compliance and increasing corporate ESG commitments should buoy the sector for years to come. On the other hand, environmental regulations continue to evolve, and this may require costly upgrades, volatility in commodity waste and recycling markets, and labor shortages in industrial services. As for digitization, a theme that is impacting nearly every industry, the increasing use of data, analytics, and automation will give rise to improved efficiency of operations. Conversely, though, the benefits of digitization also come with challenges of integrating new technologies into legacy systems.
