Amerant Bancorp Inc.

The second quarter of 2026 was characterized by a U.S. economy that continued to expand but at a more moderate pace. Economic growth remained supported by business investment, particularly technology and AI-related infrastructure spending, while consumer activity showed signs of slowing as inflation and higher interest rates weighed on household budgets. Consensus forecasts for 2026 GDP growth generally remained in the 2.0% to 2.2% range, reflecting a resilient but decelerating economy. While overall U.S. growth softened, economic activity in the markets we serve remained relatively stable; Management believes the second quarter reflects Amerant’s deliberate recalibration of its risk appetite and increased focus on lending to borrowers with stable, well established operating histories.

Business investment was mixed: spending on data centers, AI‑related infrastructure, and intellectual property remained relatively strong, while more traditional capital expenditures softened amid uncertainty around tariffs, interest rates, and global demand, resulting in a more uneven loan demand profile by sector for Amerant. The labor market remained resilient but continued to cool. Unemployment hovered in the mid‑4% range, broadly consistent with late‑2025 levels, while monthly job gains moderated from earlier post‑pandemic norms. Hiring strength in health care, government, and select technology fields contrasted with softening conditions in interest‑sensitive sectors such as housing and manufacturing. For Amerant, this environment supported overall credit performance but warranted heightened monitoring of rate‑sensitive industries, contributing to Amerant’s proactive credit risk management, targeted de‑risking actions, and exit of certain non‑core exposures.

The financial services industry is constantly undergoing rapid technological changes with frequent introductions of new technology-driven products and services, including the increased usage of artificial intelligence and intelligent automation within the industry. Our future success will partially depend upon our ability to use technology effectively to provide products and services that will satisfy our customer needs and to create additional efficiencies in our operations. We may be unable to effectively implement new technology-driven enhancements of products and services or be successful in marketing such products and services to our customers. In addition, our implementation of certain new technologies, such as those related to artificial intelligence and automation, in our processes may have unintended consequences due to their limitations or our failure to use them effectively.

We, as other financial institutions, are inherently exposed to fraud risk. Fraudsters are leveraging new technologies, including artificial intelligence, to impersonate our customers and/or steal personally identifiable information to commit fraud. Fraudulent activity can take many forms and has increased as new products and features that facilitate the access for financial services are implemented, such as real-time payment services. We are susceptible to fraud being perpetrated by customers, employees, vendors, or members of the general public. We are subject to fraud risk in connection with loan origination, payment transactions (including ACH transactions, wire transactions, and digital payments), ATM transactions, checking, withdrawal transactions and other transactions. In connection with loan origination, we significantly rely on information supplied by loan applicants and third parties, including the information contained in the loan application, appraisals of property, title information as well as employment and income documentation provided by third parties. If any of this information is misrepresented and we do not detect such misrepresentation prior to funding, we generally bear the risk of loss related to the misrepresentation. Although we are constantly investing in systems, resources, and controls aimed at mitigating fraud risk, there can be no assurance that our efforts will be effective in detecting and preventing fraud or that we will not incur fraud losses or costs or other damage related to such fraud, at levels that adversely affect our business, financial condition, results of operations, cash flows, or reputation.
