The end of the earnings season is always a good time to take a step back and see who shined (and who didn’t). Let’s take a look at how engineering and design services stocks fared in Q2, starting with MasTec (NYSE: MTZ).

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 strong Q2. As a group, revenues beat analysts’ consensus estimates by 1.5% while next quarter’s revenue guidance was 0.9% below.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 11.7% since the latest earnings results.

Market Update

Over the past year, investors have been forced to repeatedly answer the same question: what is the market’s biggest risk? The answer has changed several times, and each shift has reshaped market leadership.

Late in 2025 and early 2026, artificial intelligence became the market’s primary uncertainty. Investors questioned whether AI would erode software pricing power and weaken competitive moats as AI made it easier to replicate once-differentiated products.

By the spring, technology took a back seat to geopolitics. The U.S. conflict with Iran briefly became the market’s dominant narrative, raising concerns about oil prices, inflation, and global growth. But as energy markets remained orderly and fears of a prolonged supply disruption faded, investors quickly turned their focus back to fundamentals.
