[144] Northern Trust Corp SEC Filing

Rhea-AI Filing Summary

Form 144 filing: A security holder of Northern Trust Corp. (NTRS) intends to sell up to 23,559 common shares through Northern Trust Securities on or about 25 Jul 2025 on NASDAQ. The proposed sale carries an aggregate market value of $3.03 million and represents only ≈0.012 % of the 194.54 million shares outstanding, indicating limited dilution risk.

The shares derive from four prior vesting events: 3,447 shares (22 Jan 2018), 5,156 (20 Jan 2021), 5,015 (1 Mar 2022) and 9,941 (18 Jan 2023). The filer reports no other sales in the past three months. By signing, the seller affirms no undisclosed material adverse information and acknowledges potential criminal liability for false statements.

Insights

Securities Analyst

TL;DR: Small insider sale (0.012 % float, $3 M) appears routine; negligible fundamental impact on NTRS.

The planned disposition of 23,559 shares is modest relative to Northern Trust’s capitalization and daily trading volume, suggesting liquidity management rather than a signal on fundamentals. Absence of recent sales and the vesting-award origin support a routine diversification motive. Market impact should be minimal unless followed by larger sequential filings.
