Nippon Life buys about $20.2 million more Corebridge Financial stock

Nippon Life Insurance Company bought another roughly $20.2 million of Corebridge Financial stock, adding to its stake in the U.S. annuity and life insurer, according to a Form 4 filed with the SEC on Tuesday.

The Japanese insurer bought 411,516 shares on Oct. 23 at a reported price of $33.7365 and another 184,093 shares at $34.4802, the filing shows. That is 595,609 shares for about $20.23 million in total.

Bought under a trading plan

The filing says the purchases were made under a Rule 10b5-1 trading plan that Nippon Life adopted on Aug. 7, 2026. Such plans set purchase or sale instructions in advance, so the timing of individual trades is not chosen day by day.

A large and growing holder

After the purchases, Nippon Life holds 131,262,715 Corebridge shares, according to the Form 4. Nippon Life files insider reports on Corebridge because of the size of its stake, which makes it one of the company's largest shareholders.

The latest filing follows an earlier Form 4 that showed Nippon Life buying about $8.7 million of Corebridge stock, which Investor Data Digest reported on Tuesday morning.

Why it matters

Steady buying by a strategic holder is a signal investors tend to watch, because it shows a large, well-informed shareholder adding to its position rather than trimming it. In this case, the purchases are being made in increments under a plan set months ago, so they show a continuing intention to build the stake rather than a reaction to a single day's events.

The filing does not say how many more shares Nippon Life may buy under the plan or when the plan ends.
