# Motorola Solutions CEO Gregory Brown Has Now Sold Over $1 Billion in MSI Stock — His Latest $13.5M Sale Came After Record Q4

> Gregory Brown, Chairman and CEO of Motorola Solutions, sold $13.5 million in MSI shares on March 4-6, 2026, following record Q4 2025 revenue. His career insider sales now exceed $1.09 billion.

Gregory Brown, Chairman and CEO of Motorola Solutions (MSI), has now sold more than $1.09 billion in company stock over his career — making him one of the most prolific insider sellers among active S&P 500 CEOs. His latest round of sales, totaling approximately $13.5 million across March 4–6, 2026, came just weeks after Motorola Solutions reported record Q4 2025 revenue and outlined an ambitious 2026 growth roadmap anchored by its Silvus Technologies acquisition and AI-powered product suite. Brown's selling pattern is remarkably consistent: exercise stock options, then sell within days. With 903 career transactions on file and only $2 million in lifetime purchases against $1.09 billion in sales, the pattern speaks for itself. After the latest round of exercises and sales, Brown retains just 6,400 shares of MSI. Transaction Timeline: February–March 2026 Brown executed a concentrated burst of activity over a three-week window: Date Type Shares Approx. Price Approx. Value Feb 24, 2026 Sale 50,000 ~$474 ~$23.7M Feb 25, 2026 Sale (multiple lots) 21,600 $464–$468 ~$10.1M Mar 4–6, 2026 Sale 28,435 ~$475 ~$13.5M Mar 13, 2026 Exercise (M) 14,060 — — Mar 14, 2026 Exercise (M) 15,362 — — The February 25 sales broke into four separate lots at incrementally higher prices — $464.17, $465.64, $466.58, and $467.89 — consistent with a pre-arranged 10b5-1 trading plan executed across price tiers. The March 13–14 exercises added nearly 30,000 shares through option conversions, which typically feed the next wave of sales. You can track all of Gregory Brown's Form 4 filings in real time on his insider profile. Record Quarter Sets the Stage Brown's sales followed a strong Q4 2025 earnings report from Motorola Solutions. The company posted record quarterly revenue, driven by robust demand across its Safety & Security and Communications segments. Management issued 2026 guidance projecting $675 million in revenue from its recently acquired Silvus Technologies, alongside 10–11% growth in its software and services business and 15% growth in its command center solutions. The company also began rolling out its AI Assist Suites, a product family embedding artificial intelligence across its public safety and enterprise communications platforms. Brown presented the company's growth strategy at the Raymond James Institutional Investors Conference on March 2, 2026 — two days before the $13.5 million sale commenced. The Pattern: A Decade-Plus of Systematic Selling Brown's insider transaction history reveals a selling machine. Across 903 career transactions, the overwhelming majority are option exercises immediately followed by open-market sales. His $1.09 billion in cumulative sales dwarfs his $2 million in lifetime purchases by a factor of roughly 545-to-1. This is not unusual for long-tenured CEOs compensated primarily through equity grants, but the sheer scale is notable. Brown has led Motorola Solutions since the company's 2011 split from Motorola Mobility, and MSI stock has appreciated roughly tenfold under his tenure — providing the fuel for billion-dollar-plus liquidation. With only 6,400 shares remaining after the latest round, Brown's direct ownership is minimal relative to his compensation history. Future Form 4 filings will reveal whether additional option exercises replenish his holdings for continued selling. Key Facts Metric Value Career Transactions 903 Career Sales $1.09 billion Career Purchases $2.0 million Latest Sale (Mar 4–6) ~$13.5 million (28,435 shares) Shares Remaining 6,400 Top Institutional Holder Vanguard Group (13.3%) Other Major Holders BlackRock (9.3%), Capital World Investors (6%) What to Watch Silvus integration progress: The $675M revenue target for 2026 is a key benchmark. Execution risk on defense-tech integrations could affect MSI's premium valuation. AI revenue contribution: The AI Assist Suites rollout is early. Watch for concrete revenue disclosures in upcoming quarters. Next Form 4 filings: Brown's March 13–14 exercises typically precede sales within days to weeks. Monitor his insider profile for the next tranche. Institutional positioning: With Vanguard and Capital World Investors among the largest holders, upcoming 13F filings will show whether institutions are adding or trimming alongside the CEO's sales.
