Northern Trust Corp. reported an insider ownership change involving Charles A. Tribbett in a Form 4 filed on July 2, 2026, covering activity dated July 1, 2026. The filing relates to Northern Trust common stock and identifies the reported security as stock units that are payable automatically on a one-for-one basis in shares of the company’s common stock. The document indicates that Tribbett’s reported ownership changed as of July 1, but the text provided does not include the specific transaction table normally found in a Form 4. As a result, it does not disclose the number of stock units or shares involved, the transaction code, any acquisition or disposition price, or Tribbett’s beneficial ownership after the reported transaction. The explanatory note is important because it clarifies that the units are economically tied to Northern Trust common stock and convert or settle automatically into common shares on a 1-for-1 basis. Such units are commonly used in director or executive compensation arrangements, though the provided filing text does not specify whether this action was an award, vesting event, settlement, deferral, or other transaction. The filing was signed on Tribbett’s behalf by David A. Serna, acting as attorney-in-fact, on July 2, 2026. While the filing confirms an insider-related ownership update at Northern Trust, the excerpt does not provide enough transaction-level detail to determine the size, value, or precise nature of the reported change.
