Federated Hermes Institutional Money Market Management

A Portfolio of Federated Hermes Money Market Obligations Trust

SERVICE SHARES (TICKER MMSXX)

SUPPLEMENT TO CURRENT SUMMARY PROSPECTUS, PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION

On August 11, 2023, the Board of Trustees (the “Board”) of Federated Hermes Money Market Obligations Trust approved a Plan of Conversion for the Service Shares of Federated Hermes Institutional Money Market Management (the “Fund”) pursuant to which the Service Shares of the Fund will be converted into the Fund’s existing Eagle Shares on or about October 27, 2023, resulting in the closure and termination of the Fund’s Service Shares. In approving the conversion, the Board determined that the conversion of the Service Shares into Eagle Shares is in the best interest of the shareholders of the Service Shares.

Pursuant to the Plan of Conversion, Service Shares shareholders will automatically receive shares of Eagle Shares in exchange for their Service Shares without any fee, load or charge to the shareholder, including any contingent deferred sales charges, on or about October 27, 2023. Shareholders should consult their Fund’s prospectus for additional information regarding Eagle Shares expenses.

The conversion will occur on a tax-free basis. The cash value of a shareholder’s investment will not change as a result of the share class conversion. Service Shares shareholders will receive Eagle Shares with a total dollar value equal to the total dollar value of the Service Shares owned at the time of conversion. With respect to the Fund, the Eagle Shares into which shareholders will be converted currently offer the same total gross and net expense ratios as the Service Shares.

No action is required by shareholders to effect the conversion. There will be no disruption to their accounts.

Please delete all references to Service Shares effective as of October 27, 2023.
