#### Forward-Looking Statements
This Current Report on Form 8-K contains statements that constitute "forward-looking statements" within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are forward-looking statements. These forward-looking statements include, but are not limited to, statements about the benefits of the proposed transaction between Synovus Financial Corp. ("Synovus") and Pinnacle Financial Partners, Inc. ("Pinnacle"), including future financial and operating results (including the anticipated impact of the proposed transaction on Synovus' and Pinnacle's respective earnings and tangible book value), statements related to the expected timing of the completion of the proposed transaction, the combined company's plans, objectives, expectations and intentions, and other statements that are not historical facts. You can identify these forward-looking statements through the use of words such as "believes," "anticipates," "expects," "may," "will," "assumes," "should," "predicts," "could," "would," "intends," "targets," "estimates," "projects," "plans," "potential" and other similar words and expressions of the future or otherwise regarding the outlook for Synovus', Pinnacle's or combined company's future businesses and financial performance and/or the performance of the banking industry and economy in general.

Prospective investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve known and unknown risks and uncertainties which may cause the actual results, performance or achievements of Synovus, Pinnacle or the combined company to be materially different from the future results, performance or achievements expressed or implied by such forward-looking statements. Forward-looking statements are based on the information known to, and current beliefs and expectations of, Synovus or Pinnacle and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this Current Report on Form 8-K. Many of these factors are beyond Synovus', Pinnacle's or the combined company's ability to control or predict. These factors include, among others, (1) the risk that the cost savings and synergies from the proposed transaction may not be fully realized or may take longer than anticipated to be realized, (2) disruption to Synovus' business and to Pinnacle's business as a result of the announcement and pendency of the proposed transaction, (3) the risk that the integration of Pinnacle's and Synovus' respective businesses and operations will be materially delayed or will be more costly or difficult than expected, including as a result of unexpected factors or events, (4) the failure to obtain the necessary approvals by the shareholders of Synovus or Pinnacle, (5) the amount of the costs, fees, expenses and charges related to the transaction, (6) the ability by each of Synovus and Pinnacle to obtain required governmental approvals of the proposed transaction on the timeline expected, or at all, and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company after the closing of the proposed transaction or adversely affect the expected benefits of the proposed transaction, (7) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the proposed transaction, (8) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in closing the proposed transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, (9) the dilution caused by the issuance of shares of the combined company's common stock in the transaction, (10) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (11) risks related to management and oversight of the expanded business and operations of the combined company following the closing of the proposed transaction, (12) the possibility the combined company is subject to additional regulatory requirements as a result of the proposed transaction or expansion of the combined company's business operations following the proposed transaction, (13) the outcome of any legal or regulatory proceedings or governmental inquiries or investigations that may be currently pending or later instituted against Synovus, Pinnacle or the combined company and (14) general competitive, economic, political and market conditions and other factors that may affect future results of Synovus and Pinnacle including changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; and capital management activities. Additional factors which could affect future results of Synovus and Pinnacle can be found in Synovus' or Pinnacle's filings with the Securities and Exchange Commission (the "SEC"), including in Synovus' Annual Report on Form 10-K for the year ended December 31, 2024, under the captions "Forward-Looking Statements" and "Risk Factors," and Synovus' Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and Pinnacle's Annual Report on Form 10-K for the year ended December 31, 2024, under the captions "Forward-Looking Statements" and "Risk Factors," and in Pinnacle's Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. Undue reliance should not be placed on any forward-looking statements, which are based on current expectations and speak only as of the date that they are made. Synovus and Pinnacle do not assume any obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as otherwise may be required by law.

LFI Assessment Background and Approach Synovus conducted a future state gap assessment of current capabilities compared to incremental regulatory requirements and supervisory expectations for a Large Financial Institution (LFI) with assets between $100Bn and $250Bn. Background and Scope Approach Assessment performed against incremental regulatory requirements (e.g., Regulation YY), supervisory expectations, and peer practices that would be expected as we grow beyond $100Bn. Scope spanned regulatory reporting, data and technology, capital, liquidity and risk management capabilities required for organizations with assets between $100Bn and $250Bn. Deep dive on regulatory reporting and data and technology with more targeted reviews of risk management, capital planning, and liquidity risk management. Proactively conducted assessment to identify areas of capability gaps and provide recommendations on next steps for us to align to LFI expectations. Defined regulatory requirements and supervisory expectations for an LFI with assets between $100Bn and $250Bn. Performed an LFI Readiness assessment through workshops and review of supporting artifacts to identify and outline key activities for near-term/long-term planning required to achieve target state LFI requirements. Developed recommendations bifurcated between near-term and long-term, including program cost estimates, resourcing, and implementation timelines. Implementation horizon is in line with MOE-driven timelines Source: SNV internal report
