The U.S. insurer seeks to gradually reduce its stake in its Corebridge Financial Inc unit and had planned the share sale in the first quarter.
Corebridge, which listed on the stock market in September last year after a multi-year effort by AIG to separate the business, has seen its shares drop by more than 20% since going public.
"We remain committed to reducing our ownership interest in Corebridge and will explore other options that are aligned with the best interest of shareholders," CEO Peter Zaffino told analysts on an earnings call.
AIG on Thursday beat Wall Street estimates for first-quarter profit on strong underwriting gains.
