Nippon Life Insurance Company bought 4,614,523 more shares of Corebridge Financial between September 9 and October 2, paying roughly $158,225,595, according to a [Schedule 13D amendment](https://www.sec.gov/Archives/edgar/data/0000905591/000119312526415635/xslSCHEDULE%5F13D%5FX01/primary%5Fdoc.xml?ref=bullished.co) filed Tuesday. The filing, Amendment No. 5, adds no new demands and no stated plans for the company.

## What the amendment says

Nippon Life reports [126,604,050 shares](https://www.sec.gov/Archives/edgar/data/0000905591/000119312526415635/xslSCHEDULE%5F13D%5FX01/primary%5Fdoc.xml?ref=bullished.co), or 28.4% of the class, with sole voting power over all of them and none shared. The percentage rests on 445,772,522 shares outstanding as of July 31, a count the filing takes from Corebridge's 10-Q filed August 5.

The purchases were open-market trades under a previously disclosed 10b5-1 plan, a pre-scheduled trading plan filed with the SEC. Nippon Life says it paid with working capital.

The holding includes 126,570,779 shares held of record by Nippon Life and 33,271 shares held of record by Nissay Asset Management Corporation, a direct wholly owned subsidiary that Nippon Life may be deemed to beneficially own.

## What it changes

Only two items carry new content. Item 3, on the source of funds, was supplemented to report the buying, and Item 5, on ownership, was restated. The text supplied includes no board letter, nominations, demands or strategic-alternatives language.

For holders, the change is a larger stake held by the same filer under the same plan, with the 13D's date of event set at October 2.

## What to watch

Annex A to the filing lists each purchase date with the weighted average, high and low prices. Nippon Life also undertakes to give the SEC staff, the company or a shareholder the number of shares bought at each separate price, on request.

Any further buying or selling under the trading plan would have to appear in a later amendment.
