Leases | Note 7 — Leases As of March 31, 2026 and December 31, 2025, we had operating right-of-use (“ROU”) assets of $500.3 million and $507.1 million, respectively, and operating lease liabilities of $520.5 million and $525.3 million, respectively. We maintain operating leases on land and buildings for some of our operating centers, branch facilities and ATM locations. Most leases include one or more options to renew, with renewal terms extending up to 20 years. The exercise of renewal options is based on the sole judgment of management and what they consider to be reasonably certain given the environment today. Factors in determining whether an option is reasonably certain of exercise include, but are not limited to, the value of leasehold improvements, the value of renewal rate compared to market rates, and the presence of factors that would cause a significant economic penalty to us if the option is not exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet and instead are recognized in lease expense on a straight-line basis over the lease term. ​

​ Terms and conditions are similar to those real estate operating leases described above. Lease classifications from the acquired institutions were retained. At March 31, 2026, we did not maintain any leases with related parties, and determined that the number and dollar amount of our equipment leases was immaterial. As of March 31, 2026, we had no operating leases that had not yet commenced. ​ Sale-leaseback Transaction On February 28, 2025, the Bank completed a sale-leaseback transaction for the purchase and sale of real property (the “Sale Agreement”) with entities affiliated with Blue Owl Real Estate Capital LLC (“Blue Owl”), providing for the sale to entities affiliated with Blue Owl of 165 bank branch properties owned and operated by the Bank (collectively, the “Branches”). The Branches are located in Alabama, Florida, Georgia, North Carolina, South Carolina and Virginia. The sales price for the Branches was $467.2 million, and the Company recorded a gain on sale of the Branches of $229.3 million (net of transaction costs). Under the Sale Agreement, the Bank has agreed, concurrently with the closing of the sale of the Branches, to enter into triple net lease agreements (the “Lease Agreements”) with entities affiliated with Blue Owl, pursuant to which the Bank will lease each of the Branches (the “Sale-leaseback Transaction”). Each of the Lease Agreements will have initial terms of 15 years and provide the Bank with three consecutive renewal options of five years each. The Lease Agreements also will include a 2% annual rent escalation during the initial term and the renewal terms. With the Sale-leaseback Transaction, the Company recorded an additional lease right of use assets of $361.1 million. Equipment Lessor SouthState has an Equipment Finance Group which does business directly with customers and primarily focuses on serving the construction and utility segments. Lease terms typically range from 24 months to 120 months. At the end of the lease term, the lessee has the option to renew the lease, return the equipment, or purchase the equipment. In the event the equipment is returned, there is a remarketing agreement with the intermediary to sell the equipment. The Equipment Finance Group offers the following lease products: TRAC Leases, Split-TRAC Leases, and FMV Leases. Direct finance equipment leases are included in commercial and industrial loans category, which is included in the Non-acquired Loans on the Consolidated Balance Sheets. ​ The estimated residual values for direct finance leases are established by an approved intermediary who utilizes internally developed analyses, external studies, and/or third-party appraisals to establish a residual position. FMV and Split-TRAC leases have residual risk due to their unguaranteed residual value whereas TRAC leases have a guaranteed residual value. Expected credit losses on direct financing leases and the related estimated residual values are included in the Commercial and Industrial loan segment for the ACL. ​ The following table summarizes lease receivables and investment in operating leases and their corresponding balance sheet location at March 31, 2026 and December 31, 2025: ​
