| Schedule of Segment Reporting Information |
The following tables present certain financial information for each reportable business segment for the three and six months ended June 30, 2026 and 2025 and as of June 30, 2026 and December 31, 2025. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable business segment may be periodically revised. Loan and deposit transfers occur from time to time between reportable business segments primarily to maintain the migration of clients and relationship managers between segments; however, prior period loan and deposit balances and any related net interest income and FTP are not adjusted for transfers. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended June 30, 2026 | | (in millions) | Banking | | | | | | Wealth | | Treasury and Corporate Other | | Pinnacle Consolidated | | Net interest income | $ | 807 | | | | | | | $ | 10 | | | $ | 139 | | | $ | 956 | | | Provision for (reversal of) credit losses | 62 | | | | | | | — | | | 1 | | | 63 | | | Net interest income after provision for credit losses | 745 | | | | | | | 10 | | | 138 | | | 893 | | | Core banking fees | 81 | | | | | | | — | | | 12 | | | 93 | | | Wealth management revenue | 5 | | | | | | | 80 | | | — | | | 85 | | | Capital markets income | 18 | | | | | | | — | | | — | | | 18 | | | Total loan sales and servicing | 9 | | | | | | | — | | | — | | | 9 | | | | | | | | | | | | | | | | | | | | | | | | | | | Other non-interest revenue | 9 | | | | | | | — | | | 33 | | | 42 | | | Total non-interest revenue | 122 | | | | | | | 80 | | | 45 | | | 247 | | | Salaries and other personnel expense | 205 | | | | | | | 48 | | | 125 | | | 378 | | | Occupancy, equipment and software expense | 40 | | | | | | | 1 | | | 61 | | | 102 | | Other operating expense(1)(2) | 61 | | | | | | | 9 | | | 171 | | | 241 | | | Total non-interest expense | 306 | | | | | | | 58 | | | 357 | | | 721 | | | Income (loss) before income taxes | $ | 561 | | | | | | | $ | 32 | | | $ | (174) | | | $ | 419 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
