“Bottom contributors in Q3 included FTAI Infrastructure and Mesa Laboratories, Inc. (NASDAQ:MLAB). Mesa Laboratories provides life sciences tools and quality control products and services. The company navigated a challenging macroeconomic environment with modest growth — though profitability was pressured by currency impacts, tariffs and timing delays. These order timing issues also weighed on organic growth, as did China-related headwinds. However, positively, Mesa’s largest segment, sterilization and disinfection control, delivered solid core growth, speaking to the resilience of the company’s diversified portfolio.”
