Stock Splits, IPOs and S&P 500 Ex-Dividend Dates: Week of Oct 26, 2026

No stock splits this week, one IPO expected on the NYSE, and 21 S&P 500 companies go ex-dividend, led by Caterpillar and Costco.

This week brings zero $2 billion-plus stock splits, one expected IPO, and 21 S&P 500 ex-dividend dates. The single IPO is Gunnison Copper Corp. on the NYSE, while the ex-dividend list includes large names such as Caterpillar, Costco and Morgan Stanley.

Stock splits

There are no US-listed stock splits of $2 billion or more scheduled this week.

A stock split changes the number of shares a holder owns and the price per share, but it does not change the total value of the holding. A company that splits its stock simply divides existing shares into more, smaller-priced pieces.

IPOs expected this week

One IPO is expected on a US exchange this week. Gunnison Copper Corp. is expected to begin trading on the NYSE under the ticker GUNN on Monday, October 26.

As with any initial public offering, the date can move before pricing is finalized, and no price range was listed for this one.

Ex-dividend dates

Twenty-one S&P 500 companies go ex-dividend this week, spread across Monday through Friday. They include Bank of New York Mellon at $0.63 a share, Caterpillar at $1.63, Paychex at $1.19, GE Vernova at $0.50, Clorox at $1.25, Fastenal at $0.26, Carrier Global at $0.24, and a larger group clustered on Friday, October 30, including AES, A. O. Smith, Casey's General Stores, Citizens Financial Group, Costco, Humana, Alliant Energy, Morgan Stanley, NiSource, Realty Income, Constellation Brands, Targa Resources, Texas Instruments and Zoetis, with per-share amounts ranging from $0.18 to $1.52.

The ex-dividend date marks the first day a share trades without the right to the upcoming payment, meaning an investor who buys on or after that date does not receive that particular dividend.
