Construction Stocks Fall Despite Q1 Revenue Beats as APi, Primoris Guidance Disappoints

Construction and maintenance services stocks declined an average 4.4% since reporting first-quarter results, even after aggregate revenue exceeded analysts’ expectations by 4.7%. APi Group (NYSE:APG) led the group lower, slumping 14.6% after it issued the weakest full-year guidance among peers, overshadowing a 15.3% revenue rise to $1.98 billion on May 29, 2026. MYR Group (NASDAQ:MYRG) bucked the trend, surging 47.1% after its $1 billion revenue beat estimates by 7.5% and delivered strong EPS. In contrast, Primoris Services (NYSE:PRIM) tumbled 38.2% after missing revenue by 10.3% and lowering its 2026 EBITDA outlook. Construction Partners (NASDAQ:ROAD) fell 8.5% despite a 34.6% revenue jump to $769.2 million, while Limbach (NASDAQ:LMB) shed 30.3% even after topping profit forecasts. The broad pullback occurred as investor focus shifted from AI disruption to US-Iran geopolitical tensions, weighing on industrial cyclical stocks.
