• The company offers a full range of banking products and services for businesses, real estate professionals, and consumers across the Lowcountry of South Carolina (Hilton Head Island, Bluffton, Beaufort), Savannah, Georgia, and the Atlanta, Georgia markets.
• In addition to traditional community banking, CSB operates four specialty lines of business: Senior Housing Lending, Marine Lending, Government Guaranteed Lending (SBA and USDA), and Mortgage Banker Finance.

• Total assets grew from $413.5 million at December 31, 2016, to $2.2 billion at March 31, 2025, through organic growth, opportunistic acquisitions, and specialty lines expansion.
• For the three months ended March 31, 2025, net income was $5.1 million, up from $2.4 million in the prior-year period, primarily due to the absence of nonrecurring losses on AFS securities.
• Net interest income for Q1 2025 increased by $1.4 million (8.9%) to $16.8 million, driven by higher average loan balances and a decrease in the average rate paid on interest-bearing liabilities.
• The company reported a net interest margin of 3.38% for Q1 2025, compared to 3.21% for Q1 2024.
• Provision for credit losses increased to $629 thousand in Q1 2025 from $163 thousand in Q1 2024, attributed to new loan production and commitments, offset by a reduction in reserves for a collateral-dependent nonaccrual loan.
• Nonperforming assets to total assets decreased to 0.70% at March 31, 2025, from 0.76% at December 31, 2024, with 32.1% ($4.7 million) of nonaccrual loans covered by government guarantees.
• The company's net charge-off ratio to average loans held-for-investment was 0.00% for the three months ended March 31, 2025, and 0.01% for the year ended December 31, 2024.
• Total deposits increased by $102.9 million (5.6%) to $1.94 billion at March 31, 2025, with noninterest-bearing deposits comprising 15.5% of the total.
• The company plans an initial public offering of its voting common stock and has applied to list on the New York Stock Exchange (NYSE) under the symbol COSO.
• The estimated initial public offering price is between $ and $ per share, with the company not receiving proceeds from selling shareholders' shares.

• Largest loan relationships (top 10 loans represent 10.1% of LHFI at March 31, 2025) pose concentration risk if one or more become delinquent.

• Environmental liability risk associated with lending activities and foreclosed real estate.
• Lack of liquidity or increased cost of liquidity could impair funding operations and jeopardize financial results.
• High proportion of deposit account balances exceeding FDIC insurance limits (36.1% at March 31, 2025) may expose the company to enhanced liquidity risk during financial distress.

• Internal controls may be ineffective, leading to inaccurate financial reporting, fraud, or non-compliance.
• Inability to attract and retain skilled people, particularly key employees with extensive customer relationships, could disrupt business.

• Common stock is subordinate to existing and future indebtedness.
• Potential future issuance of preferred stock could adversely affect common stock holders and depress price.

Industry Context

CoastalSouth Bancshares operates in the highly competitive U.S. financial services industry, particularly within the community banking sector. The company highlights its competitive advantage by combining traditional community banking with specialized national lending lines, a model more common in larger regional or national banks. It benefits from the ongoing consolidation in the community banking space, which reduces local competition and creates opportunities to attract clients and bankers from merged institutions. The company's focus on fast-growing Southeast MSAs (Atlanta, Savannah, Hilton Head Island) positions it in demographically strong markets. While facing competition from larger institutions with greater resources, CoastalSouth aims to differentiate through relationship-based service and customized client experiences, leveraging its 'scarcity value' as one of the few independent banks in its asset range in the region. The document also notes industry-wide pressures like compressing net interest margins and rising operating costs (technology, compliance, personnel).
