First Guaranty Bancshares (FGBI): customer relationships that shape liquidity and exit strategy

First Guaranty Bancshares operates as a regional commercial bank holding company centered on First Guaranty Bank, which attracts deposits from consumers, small businesses and municipalities and then converts those deposits into loan assets and other investments. The company monetizes through net interest margin on loans and securities, fee income from deposit and digital services, and occasional portfolio optimization via branch and book sales; recent activity shows management is actively reshaping footprint and balance sheet to shore up capital and improve Tier 1 ratios. For a concise view of partner and counterparty exposures that drive funding and exit dynamics, read on.

How FGBI’s customer mix and contract posture determine economic sensitivity

First Guaranty’s business model is deposit-led lending: deposits (including a substantial public funds component) are the primary funding source for a portfolio of commercial, residential and construction loans. That structure produces a blend of short-term and long-term contractual exposures across the balance sheet:

• Construction and commercial short-term lending and many public-fund deposit arrangements create a short-term contracting posture for a material portion of funding. Management disclosures note construction loans are generally up to 24 months and public funds fiscal-agency agreements frequently run three years or less.
• The bank also holds long-duration assets—one- to four-family residential loans up to 30 years and brokered time deposits with two- to three-year maturities—introducing duration mismatch and interest-rate sensitivity.

These characteristics translate into three actionable investor conclusions: concentration risk around public funds (30.1% of deposits at year-end 2024), funding fragility if local-government flows change, and capital and margin sensitivity to asset disposals or branch sales. The company is also expanding digital services (online/mobile banking, bill pay and credit-awareness tools), which is a product diversification vector rather than a material redefinition of the deposit-lending model.

What recent public filings and press releases reveal about counterparties

Below I cover every relationship captured in recent filings and press coverage.

Smith & Tate Investment — related-party borrower with amended loans

First Guaranty amended two loan agreements with Smith & Tate Investment, a company led by Edgar Ray Smith III who is both a director and principal shareholder of First Guaranty, indicating related-party lending and contractual renegotiation within FY2026. According to an SEC-related report carried by Investing.com, the amendment was disclosed in early May 2026 and links governance and credit decision channels at the bank.

Armstrong Bank — acquirer of Texas branches and deposits (reported via TradingView)

First Guaranty signed an agreement to sell its Texas operations — five branches with approximately $270 million of deposits and $110 million of loans — to Armstrong Bank, a transaction explicitly framed as an operational exit from that market and a Tier 1 capital improvement. TradingView’s coverage referenced the deal terms in May 2026, underlining the company’s use of asset sales to rebalance capital and reduce geographic diversification.

Armstrong Bank of Muskogee, Oklahoma — purchaser in definitive purchase-and-assumption agreement

The sale of the Texas operations was memorialized as a definitive purchase-and-assumption agreement with Armstrong Bank of Muskogee, Oklahoma, covering the Dallas–Fort Worth and Waco branches and confirming counterparty identity and transactional certainty. First Guaranty announced the agreement on March 10, 2026; public filings and press releases in March–May 2026 treated this as a completed disposition agreement that materially alters the deposit base and loan book exposure in Texas.

What those relationships imply for investors and operators

• Related-party credit visibility is elevated: The Smith & Tate Investment amendments show the board is directly linked to a borrower, which creates governance and credit monitoring priorities for investors. That relationship warrants scrutiny in loan-loss provisioning and insider-lending controls.
• Balance-sheet reshaping is active and material: The Armstrong transactions remove a meaningful slice of deposits ($270M) and loans ($110M) from FGBI’s footprint and provide an explicit path to strengthen Tier 1 capital. That sale is a deliberate tactical lever to reduce geographic diversification and shore up capital ratios.
• Funding concentration is a structural risk: Company disclosures confirm public funds accounted for roughly 30.1% of deposits at 12/31/2024, making municipal and other government-related deposit flows a material and cyclically sensitive funding source. Any local government displacements or policy shifts would have an outsized balance-sheet impact.
• Contract duration is mixed and operationally consequential: The firm operates with both short-term contracts (construction loans, short fiscal-agency deposits) and long-term exposures (residential mortgages up to 30 years, multi-year brokered deposits), producing interest-rate and repricing mismatches that management offsets through asset sales and capital moves.

Operational constraints and what they signal about execution risk

Treat these company-level signals as the frame through which partner relationships should be assessed:

• Contracting posture: both short- and long-term contracts coexist; the bank does not commonly enter long-term revenue contracts with customers, limiting contract asset buildup.
• Counterparty mix: Government/public funds are material and concentrated, while small business, individual, mid-market and occasional syndicated exposures diversify loan composition.
• Geography: The franchise is regional — primarily Louisiana and Texas — which concentrates policy and economic exposure to those states.
• Maturity and criticality: A significant share of funding is retained public funds with three-year or shorter fiscal agreements, which are critical to liquidity but operationally replaceable only at potential cost.

These constraints mean management will continue to use targeted asset disposals and branch sales (the Armstrong transactions) and selective loan amendments (Smith & Tate) to manage regulatory capital and local-market risk.

Bottom line for investors evaluating FGBI relationships

First Guaranty’s customer and counterparty relationships are a mix of material public-fund reliance, strategic asset sales, and localized credit relationships that intersect with insider governance. The Armstrong transactions materially reduce deposit concentration and adjust capital ratios; the Smith & Tate amendments highlight governance-connected credit activity that investors must monitor for transparency and provisioning.

Key takeaway: FGBI is executing a deliberate balance-sheet reshaping program while operating in a regional, deposit-dependent model where public funds concentration and related-party lending are the primary relationship risks.
