Pursuant to the Redemption Notice, on December&#160;29, 2025 (the &#8220;Redemption Date&#8221;), the Company will redeem any and all outstanding Preferred Securities at a redemption price in cash equal to 100% of the principal amount of such Preferred Securities to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date.
