On September 14, Hewlett Packard Enterprise declined 10.45% in regular trading, trading at $55.655/share, with turnover of approximately $160 million. The steep drop was driven by a confluence of negative catalysts, including calls from major AI companies to slow AI model development and a disclosed plan by the company's CEO to sell a significant block of shares.

On the industry front, three leading AI companies — including OpenAI and Anthropic — publicly urged a deceleration in AI research, triggering broad-based selling across cloud computing and AI infrastructure names. NEBIUS and CoreWeave fell over 6%, while Oracle dropped more than 3%. Notably, investor Michael Burry criticized the initiative as self-serving, suggesting it may serve to shield incumbents from competition or mask slowing growth trajectories.

Compounding the pressure, President and CEO Antonio F. Neri recently filed a Form 144 disclosing plans to sell 750,000 shares valued at approximately $41.415 million through J.P. Morgan Securities. The broader hardware sector also traded sharply lower, with SanDisk down 7.13%, Western Digital down 6.74%, Seagate down 7.09%, and Dell down 6.55%. While HPE's Q3 results significantly beat expectations and management raised full-year adjusted EPS guidance to $3.75–$3.85 versus the $3.44 estimate, ongoing supply chain constraints limiting AI server delivery left the post-earnings rally vulnerable to reversal.
