Insights

Insider Transactions Analyst

Routine Regulation 144 notice listing multiple 10b5-1 sales by an executive.

The filing itemizes a sequence of 10b5-1 sales by Patrizio Vinciarelli through Morgan Stanley Smith Barney LLC, with discrete share counts and trade dates, including two 50,000-share entries on 03/05/2026 and 03/04/2026.

These notices document reported dispositions rather than corporate actions; subsequent Form 4/144 or broker confirmations could disclose additional timing or amounts. Investors may review later filings for cumulative insider selling activity.

The December 2025 entries show multiple 10b5-1 sales with individual share counts (for example, 20,000 and 12,400). They document executed dispositions but are routine insider sales disclosed under Regulation 144.

What should investors look for after this VICR filing?

Monitor subsequent insider filings for cumulative disposition totals and any additional 10b5-1 notices. Future Form 4 or broker confirmations may report further sales or adjustments to scheduled plans.
