Let’s dig into the relative performance of Regal Rexnord (NYSE: RRX) and its peers as we unravel the now-completed Q1 engineered components and systems earnings season.

Engineered components and systems companies possess technical know-how in sometimes narrow areas such as metal forming or intelligent robotics. Lately, automation and connected equipment collecting analyzable data have been trending, creating new demand.

CEO Louis Pinkham commented, "Our growth outlook continued to strengthen during the first quarter, with enterprise daily orders up 8.5% versus the prior year. Our AMC segment led the way, with orders up over 34%, aided by growth across all markets, but particularly in aerospace & defense, discrete automation, data center and medical. Our IPS business also saw order acceleration in its distribution business and high single digit growth in its short cycle OEM business, consistent with improving industrial macro metrics, such as the ISM. PES orders were down as expected, but less severely, as residential HVAC markets show tentative signs of normalizing. We also saw continued strength in commercial HVAC, primarily driven by data center demand. While some of the enterprise order strength is tied to improving industrial and automation markets, our growth investments are also paying off, and our cross-sell initiatives continue to contribute nicely."

Market Update

Late in 2025 into early 2026, there was hand wringing around artificial intelligence. For software companies, the fear was that AI would erode pricing power and compress margins as new tools made it easier to replicate what once required expensive enterprise platforms. Crypto investors had their own version of the same anxiety: if AI agents could trade, allocate capital, and manage wallets autonomously, what exactly was the long-term value of today’s crypto infrastructure?

These concerns triggered a noticeable rotation away from these sectors and into safer havens. But markets rarely dwell on one narrative for long. Spring 2026 came, and the focus shifted abruptly from technological disruption to geopolitical risk. The US’ conflict with Iran became the dominant driver of market psychology, and when geopolitics takes center stage, the script changes quickly. Investors stop debating growth rates and start worrying about oil supply, inflation, and global stability.
