NEW YORK Shares of retirement services provider Corebridge Financial fell more than 6% on Tuesday as parent American International Group Inc looks to sell down its controlling stake.

Insurance giant AIG will sell 65 million shares, or about 10% of its total Corebridge holding, which is valued at nearly $1.1 billion.

The share sale will reduce AIG's Corebridge stake to about 67%, with private equity firm Blackstone Inc retaining its 9.9% holding, a regulatory filing showed on Monday.

Corebridge's shares were last trading at $16.96, down 4.1%.

Corebridge was formed in 2021 when AIG spun off its life and retirement business and sold a portion of the company to Blackstone for $2.2 billion.

AIG took Corebridge public in September last year, in a share offering that raised $1.7 billion at $21 per share.

Last month, AIG said it had postponed a secondary share sale due to heightened market volatility fueled by the banking crisis.
