AAON is trading 5.8% down at $89.30 as investors focus on rapid-expansion costs and lower margin expectations despite a strong second-quarter earnings beat.

  • Revenue doubled to $627 million, while diluted EPS rose 257.9%, led by BASX data-center demand and improved manufacturing throughput.
  • Management raised full-year 2026 sales-growth guidance to 55%-60% from 40%-45%, but lowered margin expectations as capacity-ramp costs increase.
  • The modestly weaker market backdrop does not explain the company-specific decline.
