Aalberts shares plunge on weaker outlook and H1 miss

** Shares in Dutch industrial technology company Aalberts AALB fall 13.6% after it cut its full-year guidance and reported first-half results below expectations

** The company adjusted its full-year 2025 EBITDA margin outlook to between 13% and 14%, citing "lower volume" in its industry and semiconductor segments

** "The H1-25 results were clearly a miss, driven by weaker than expected organic sales growth," Degroof Petercam analysts say

** The broker adds that the outlook has weakened due to reasons including "tariffs, macro-economic uncertainty, and/or exchange rates"

** Shares on track for the worst day since March 2020
