The most prominent clear emerging threat to Prosperity Bancshares (PB) is the accelerating shift towards digital-first financial services providers. This encompasses dedicated neobanks, various fintech platforms, and large technology companies that are increasingly entering the financial sector.

These entities offer increasingly convenient, often lower-cost, and technologically advanced alternatives for traditional banking products such as deposits, payments, and various forms of lending (e.g., personal loans, small business financing, "buy now, pay later" services). This trend directly challenges the traditional branch-based banking model upon which Prosperity Bancshares primarily operates.

Evidence of this emerging threat includes:

• Neobanks and Fintechs: Digital-only banks like Chime, Varo, and Ally Bank, alongside online lenders and payment apps, are rapidly acquiring customers, particularly younger demographics and digitally-savvy individuals and businesses. They offer superior digital experiences, faster processing times, and often lower fees compared to traditional banks, directly impacting PB's ability to attract and retain deposit accounts and originate loans.
• Big Tech in Finance: Companies such as Apple, Google, and Amazon are expanding their financial offerings beyond basic payments into areas like consumer credit (e.g., Apple Card, Apple Pay Later), savings accounts, and business financing solutions. These tech giants leverage their vast user bases and technological prowess to offer integrated financial services that can bypass or disintermediate traditional banking relationships.

This widespread shift represents a fundamental challenge to the established market share in deposits, loan portfolios, and overall customer relationships for regional banks like Prosperity Bancshares over the long term.

Prosperity Bancshares (symbol: PB) operates primarily in Texas and Oklahoma, offering a range of financial products and services. The addressable market sizes for their main products and services in the United States are as follows:

• Regional Banking: The market size of the Regional Banks industry in the United States is estimated at $406.5 billion in 2025.
• Commercial Banking: The US commercial banking market size is approximately $732.5 billion in 2025, with projections to reach $915.45 billion by 2030.
• Mortgage Lending: The US home loan market, representing total outstanding loans, stood at $2.29 trillion in 2025. New mortgage originations in the US totaled $1.69 trillion in 2024.
• Wealth Management: The US wealth management market, measured by Assets Under Management (AUM), was approximately $64.4 trillion in 2024 and is expected to reach $87.35 trillion by 2028.

Prosperity Bancshares (PB) is expected to drive future revenue growth over the next two to three years through several key strategies:

1. Strategic Mergers and Acquisitions (M&A) and Market Expansion: Prosperity Bancshares is actively pursuing and integrating strategic acquisitions to expand its geographic footprint and increase market share. For instance, the merger with American Bank Holding Corporation is anticipated to boost annual net interest income by $85-90 million and strengthen the company's presence in key Texas markets. Additionally, a definitive merger agreement with Southwest Bancshares, Inc., the parent company of Texas Partners Bank, is set to significantly expand Prosperity Bancshares' presence in the San Antonio metro area, enhance deposit market share, bolster its position in the Texas Hill Country, and add an experienced Commercial & Industrial (C&I) lending team. This strategy focuses on successfully identifying and integrating acquired businesses and banks.
2. Net Interest Margin (NIM) Expansion: The company has demonstrated effective interest rate management, leading to an expansion in its net interest margin. In Q2 2025, NIM expanded to 3.18%, a 24 basis point increase year-over-year. Management anticipates continued NIM expansion over the next 12 to 36 months, driven by the repricing of loans and securities, with a projected NIM trajectory of 3.35% in six months and 3.48% in twelve months. The net interest margin on a tax equivalent basis was 3.24% in Q3 2025, up from 2.95% in Q3 2024.
3. Targeted Loan Growth, particularly in Commercial & Construction: Despite a competitive lending environment, Prosperity Bancshares is focusing on selective loan growth, especially in core commercial and construction sectors. Management expects low single-digit loan growth, aided by construction deals and acquisitions, while remaining prudent in its approach to pricing and credit. The repricing opportunities for approximately $5 billion in loans and securities annually also contribute to this growth.
4. Core Deposit Growth: A continued focus on growing core deposits is a crucial driver for revenue as it provides a stable and cost-effective funding source. Prosperity Bancshares reported modest deposit growth in Q3 2025, emphasizing that core deposits remain a priority and that the bank does not utilize brokered deposits.
5. Operational Efficiency: Ongoing improvements in operational efficiency and cost control contribute to profitability and indirectly support revenue growth by optimizing resource allocation. The company's efficiency ratio improved to 45.7% in Q1 2025 from 46.1% in 2024 and was 44.1% in Q3 2025, surpassing estimates. Management has highlighted margin expansion and expense discipline as key areas.
