Insights

Equity Capital Allocation Analyst

Unum adds a new $1 billion buyback program starting in 2026.

Unum Group disclosed that its Board has authorized repurchases of up to $1 billion of outstanding common stock beginning on January 1, 2026. This authorization follows the company’s current repurchase program, which will remain in effect through December 31, 2025 and then terminate.

A buyback authorization of this size can reduce the public share count over time, depending on how much is actually repurchased and at what prices. The filing does not specify timing, pace, or methods of repurchase, so the actual effect will depend on future management decisions and market conditions.

The transition from the existing program to the new $1 billion authorization on consecutive dates provides continuity in Unum’s ability to repurchase shares. Future disclosures in company filings may detail execution under this authorization, including amounts repurchased and any changes to capital management priorities.
