Howard Hughes Holdings to Enter S&P SmallCap 600 on Oct. 28

Howard Hughes Holdings Inc. (NYSE: HHH) is set to join the S&P SmallCap 600, replacing Arcosa Inc. (NYSE: ACA) when markets open Wednesday, October 28, index operator S&P announced Thursday.

The change was triggered by an acquisition: S&P 500 component CRH plc (NYSE: CRH) completed a deal to purchase Arcosa, making the Texas-based infrastructure company ineligible for continued inclusion in the small-cap benchmark under standard index rules that exclude majority-owned subsidiaries of larger firms.

CRH, an Irish building-materials giant with a primary U.S. listing, has been an active acquirer since relocating its primary stock listing to New York in 2023.

No financial terms of the CRH-Arcosa transaction were included in the announcement. Continue reading at All Financial Services & Investing.
