The combined Pinnacle and Synovus is projected to become the fastest-growing and most profitable regional bank, achieving industry-leading financial metrics by 2027, including significant EPS accretion, rapid tangible book value earnback, and superior efficiency. The company anticipates leveraging its strong pro forma capital generation and a positive regulatory environment for larger bank mergers to drive continued growth and shareholder value, with major integration decisions expected in the second half of 2025.

• The integration is expected to be low-risk due to minimal geographic overlap, building on significant, multi-year investments made to prepare for Large Financial Institution (LFI) standards.
• Management believes the combined company will deliver top-quartile performance across key metrics, including revenue growth, return on average assets, return on average tangible common equity, and efficiency ratio.

Industry Context

This proposed merger between Pinnacle and Synovus reflects a broader trend of consolidation within the regional banking sector, particularly in high-growth markets like the Southeast. The emphasis on becoming a 'Southeast Growth Champion' and achieving 'LFI standards' highlights the strategic imperative for regional banks to scale up, enhance operational efficiencies, and meet increasing regulatory requirements to compete effectively against larger national institutions. The positive regulatory environment for larger bank mergers suggests a supportive backdrop for such strategic moves, aiming to create more robust and competitive financial entities.

Comparison to Industry Standards

• The pro forma revenue growth CAGR of 10.5% (2025E-2027E) is projected to be #1 among the peer group, which includes CFG, FITB, HBAN, KEY, MTB, PNC, RF, TFC, and USB.
• The pro forma 2027E efficiency ratio of 47% is projected to be #1 among the identified peer group, indicating superior operational efficiency.
• The pro forma 2027E return on average assets (ROAA) of 1.38% is projected to be #2 among peers, demonstrating strong asset utilization.
• The pro forma 2027E return on average tangible common equity (ROATCE) of 18.0% is projected to be #1 among peers, reflecting excellent shareholder returns.
• Pinnacle's historical performance, including delivering a total return of double the KRX since the BNC announcement (January 20, 2017-July 21, 2025) and triple the KRX since mid-2018 (June 29, 2018-July 21, 2025), suggests a strong track record of successful integration and growth compared to the broader banking index.
• The current PNFP trading at the lowest P/E among peers, despite having the strongest estimated growth, suggests a potential undervaluation relative to its industry counterparts.

Management Changes

Corporate Governance

Stakeholder Impact

• Shareholders: Expected to benefit from 21% EPS accretion by 2027, a 2.6-year TBV dilution earnback, and significant stock upside. However, they will experience dilution from the issuance of new shares and must approve the merger.
• Employees: A substantial portion of the $675 million in one-time merger costs is allocated for retention purposes (equity grants with 2-year cliff vest). Approximately 5% of the combined workforce is expected to be impacted by cost synergies. The post-close compensation model will mirror Pinnacle's existing incentive structure.
• Customers: Anticipated to benefit from continued industry-leading client service, a broader set of treasury products, and new offerings across various business segments (e.g., Family Office, Equipment Leasing, M&A Advisory).
• Suppliers/Business Partners: May face reputational risk and potential changes in relationships due to the proposed transaction and integration of operations.
• Creditors: The combined entity plans to incur $3 billion of additional long-term debt, which will impact the company's leverage profile.

Next Steps

• Obtain necessary approvals from the shareholders of Pinnacle and Synovus.
• Obtain required governmental approvals for the proposed transaction.
• Finalize major integration-related decisions in the second half of 2025, including the full organizational structure, non-core platform technology systems, and employee benefits.

Key Dates

Recommendation

The proposed merger between Pinnacle and Synovus presents a compelling investment opportunity, projecting industry-leading financial metrics including 21% EPS accretion and a rapid 2.6-year tangible book value earnback. The combined entity is expected to achieve top-tier revenue growth, efficiency, and returns on equity and assets compared to its peers. Management's detailed integration plan, conservative cost synergy estimates, and the identified potential for significant share repurchases from excess capital further de-risk the transaction and enhance shareholder value. The current valuation appears to undervalue the combined company's future growth prospects, making it a strong buy.
