Securities registered pursuant to Section 12(b) of the Act:

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

Item 1.01 Entry into a Material Definitive Agreement.

On July 2, 2026, Unum Life Insurance Company of America (the “Ceding Company”), a Maine-domiciled insurance company and a wholly owned subsidiary of Unum Group (“Unum”), entered into a Master Transaction Agreement (the “Agreement”) with Fortitude Reinsurance Company Ltd. (the “Reinsurer”), a reinsurance company organized under the laws of Bermuda, pursuant to which, among other things, on the terms and subject to the conditions set forth in Agreement, the Reinsurer has agreed to reinsure from the Ceding Company a portion of the closed block individual long-term care business written by the Ceding Company (such portion, the “Reinsured Business”). To facilitate the transactions contemplated by the Agreement, the Ceding Company will first recapture the Reinsured Business from Fairwind Insurance Company, a wholly owned subsidiary of Unum and a Vermont captive insurance company (“Fairwind”), pursuant to a partial recapture agreement (the “Partial Recapture Agreement”). The Reinsurer intends to retrocede a portion of the risk reinsured from the Ceding Company to a third-party global reinsurance partner (the “Retrocessionaire”) pursuant to a retrocession agreement (the “Retrocession Agreement”).

The closing of the transactions contemplated by the Agreement (the “Closing”) is expected to occur during 2026, subject to the satisfaction or waiver of customary closing conditions specified in the Agreement, including the receipt of required regulatory approvals for, and the Ceding Company’s entry into, the Partial Recapture Agreement, and the Reinsurer’s and Retrocessionaire’s execution of the Retrocession Agreement. The Agreement may be terminated if the Closing has not occurred on or before the date that is six months after the execution thereof.

At the Closing, the Ceding Company, the Reinsurer and, for certain limited purposes, the Retrocessionaire will enter into a Coinsurance Agreement (the “Coinsurance Agreement”), whereby, effective as of April 1, 2026 (the “Effective Date”), the Ceding Company will cede to the Reinsurer, and the Reinsurer will reinsure, on a coinsurance basis, a 100% quota share of the Reinsured Business. At March 31, 2026, Unum carried $3.8 billion of long-term care statutory reserves for the Reinsured Business in Fairwind. In connection with such reinsurance, the Agreement provides that, on the date of the Closing, the Ceding Company will transfer to the Reinsurer a pre-agreed portfolio of assets (the “Initial Portfolio”) and cash with a fair market value of approximately $5.7 billion, which amount is subject to adjustment prior to the Closing for changes in interest rates, plus certain net cash flows with respect to the Reinsured Business between the Effective Date and the Closing. Among other things, the Coinsurance Agreement provides for the Ceding Company to retain responsibility for administration and servicing of the Reinsured Policies, and for the Reinsurer to pay to the Ceding Company an experience refund based on premium rate increases realized in excess of the rate increases already reflected in the transaction economics.

The Agreement contains customary representations and warranties, as well as customary covenants of each of the parties. Such representations and warranties are the product of negotiation between the Ceding Company and the Reinsurer and are for the sole benefit of such parties and, in certain cases, the Retrocessionaire. In some instances, the representations and warranties in the Agreement may represent an allocation among the parties of risk associated with particular matters. The Reinsurer has agreed to indemnify the Ceding Company and its respective affiliates, and the Ceding Company has agreed to indemnify the Reinsurer, the Retrocessionaire and their respective affiliates, with respect to certain losses resulting from breaches of its respective representations, warranties and covenants, subject to agreed limits in the case of losses relating to representations and warranties.

At the Closing, Provident Life and Accident Insurance Company, a Tennessee-domiciled insurance company and wholly owned subsidiary of Unum (“PLA”) will provide an experience volatility cover (the “PLA Cover”) to the Retrocessionaire, subject to a cap of $125 million (in net present value terms). PLA’s payment obligations will be settled every five years and will be secured by a trust account to be funded at all times with the remaining possible payment by PLA. PLA will provide the PLA Cover in exchange for a payment from the Retrocessionaire of $5 million on the date of the Closing.

Unum expects the transaction to generate capital and tax benefits, which, combined with participation in potential future premium rate increases, will reduce the economic cost of the transaction.

The foregoing description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2026.
