Insights

Securities regulation analyst

Routine Rule 144 notice for a modest planned share sale.

This filing shows shareholder Anne DelSanto planning to sell 240 shares of Advanced Energy Industries common stock under Rule 144, using Fidelity Brokerage Services, with NASDAQ as the trading venue. The shares come from vested compensation acquired on 05/12/2023, indicating an equity-based award rather than an open-market purchase.

The disclosure also lists prior sales in the last three months: 240 shares on 10/15/2025 for gross proceeds of 44877.60, 240 shares on 11/17/2025 for 48064.80, and 240 shares on 12/15/2025 for 52416.00. These transactions are relatively small compared with the stated 37,655,384 shares outstanding, suggesting a routine liquidity event rather than a thesis-changing move.

The representation language confirms that the selling shareholder states she does not know of undisclosed material adverse information about the issuer at the time of signing, which is standard for Rule 144 activity. Overall, this reads as a normal regulatory step to permit limited secondary-market sales by an existing holder.
