Why Did AAON Plunge 14.95%? ERP Rollout, Missed Earnings

On August 11, 2025, AAON's stock experienced a significant drop of 14.95% in pre-market trading, marking a notable decline in its share price.

AAON, Inc. reported a substantial decrease in its stock value, attributed to the disruption caused by the rollout of its Enterprise Resource Planning (ERP) system. The implementation of the new ERP system has led to operational challenges, impacting the company's performance and investor confidence. Additionally, the company missed its earnings estimates for the second quarter, further contributing to the stock's decline.

The ERP rollout, intended to streamline operations and enhance efficiency, has instead created significant disruptions. These issues have not only affected AAON's day-to-day operations but also raised concerns about the company's ability to meet future financial targets. The missed earnings estimates have added to the negative sentiment, as investors reassess their expectations for the company's growth prospects.

As a result of these developments, AAON's stock has faced considerable pressure, with investors reacting negatively to the operational disruptions and financial underperformance. The company will need to address these challenges promptly to regain investor trust and stabilize its stock price.
