Motorola Solutions CEO Gregory Brown Sells $10.1M in MSI Stock — Career Total Exceeds $1 Billion

Motorola Solutions Chairman and CEO Gregory Q. Brown sold 21,600 shares of MSI stock on February 25, 2026, collecting $10.14 million in proceeds across 19 separate transactions at prices ranging from $464.17 to $469.53 per share.

The sale brings Brown's career insider selling total to over $1.09 billion — making him one of the most prolific insider sellers among current S&P 500 CEOs. He has executed 876 transactions since 2003, nearly all of them sales.

Transaction Breakdown

After the sales, Brown retains 21,580 shares of MSI stock worth approximately $10.1 million at current prices.

A Pattern of Selling

Brown has been selling MSI stock consistently for over two decades. His $1.09 billion in career sell proceeds versus just $2 million in purchases paints a clear picture: this is a CEO who monetizes equity compensation aggressively.

To put that $1.09 billion in context, Motorola Solutions' total market capitalization is approximately $79 billion. Brown has personally sold more than 1% of the company's current value over his tenure.

Also Selling: Director Kenneth Denman

Director Kenneth D. Denman sold 434 shares worth $204,000 on February 26, one day after Brown's larger sale. Denman retained 7,152 shares after the transaction.

Combined, the two insiders sold $10.35 million in MSI stock within 48 hours.

Why It Matters

While Brown's regular selling pattern means individual sales carry less signal weight, the sheer scale — over $1 billion in career proceeds — is notable. Investors tracking Motorola Solutions should note that the CEO's retained stake of ~21,580 shares represents less than 0.01% of shares outstanding.
