Chime Financial shares rise on S&P MidCap 400 inclusion

Chime Financial shares rose 1.8% in after-hours trading Friday after S&P Dow Jones Indices announced the fintech company will join the S&P MidCap 400 index, effective before market open on Wednesday, November 18. Chime will replace NorthWestern Energy Group in the index's financial sector, following NorthWestern's acquisition by Black Hills Corporation, which completed Friday. The combined company will remain in the index under the new name Bright Horizon Energy Corp. The inclusion follows Chime's third-quarter results, which showed earnings of $0.11 per share on $718 million revenue, beating analyst estimates. Management also raised fourth-quarter and full-year 2026 revenue guidance above consensus expectations.
