Item 7.01 Regulation FD Disclosure

This report is filed quarterly to disclose assets under management

(“AUM”) by asset manager, prior to the availability of Principal Financial Group, Inc's (the "Company") quarterly

earnings release. The amounts presented herein will be consistent with the format of AUM by asset manager and presented again in such

format within the Company's financial supplement for the quarter ended March 31, 2026, when that document is posted to the Company's investor

relations web site on or about April 23, 2026.

As of March 31, 2026, the assets under management for Principal Financial

Group were $770.2 billion, of which $578.0 billion is managed by Principal Asset Management - Investment Management and $159.6 billion

is managed by Principal Asset Management - International Pension.

For the quarter ended March 31, 2026, a combination of market performance,

foreign currency translation, and other items not reported as part of the Company’s net cash flow, had an approximate 1.2% negative

impact as a percentage of beginning period AUM.

During times of market dislocations and a wider dispersion of returns,

it is important to note our exposure to small, mid-cap, and international products in equity AUM, high yield and preferred securities

exposure in fixed income AUM, and exchange rate movement in emerging markets.

SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934,

the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
