Exhibit 99.1

StoneX Announces a Three-for-Two Stock Split

NEW YORK – May 26, 2026 – StoneX Group Inc. (NASDAQ: SNEX) announced today that its Board of Directors has approved a three-for-two split of its common stock to make stock ownership more accessible to employees and investors. The stock split will be effected as a stock dividend entitling each stockholder of record to receive one additional share of common stock for every two shares owned. Additional shares issued as a result of the stock dividend will be distributed after close of trading on July 17, 2026, to stockholders of record at the close of business on July 7, 2026. Cash will be distributed in lieu of fractional shares based on the opening price of a share of common stock on July 8, 2026. Trading is expected to begin on a stock split-adjusted basis at market open on July 20, 2026.

Certain statements, including, without limitation, statements regarding the expected timing and impact of the stock dividend are “forward-looking statements” that are subject to risks and uncertainties.
