ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cautionary Note Regarding Forward-Looking Statements

When included in this Quarterly Report on Form 10-Q, or in other documents that Investar Holding Corporation files with the SEC or in statements made by or on behalf of the Company, words like “may,” “should,” “could,” “predict,” “potential,” “believe,” “think,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would,” “outlook” and similar expressions or the negative version of those words are intended to identify forward-looking statements as defined by the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve a variety of risks and uncertainties that could cause actual results to differ materially from those described therein. The Company’s forward-looking statements are based on assumptions and estimates that management believes to be reasonable in light of the information available at the time such statements are made. However, many of the matters addressed by these statements are inherently uncertain and could be affected by many factors beyond management’s control. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements. These factors include, but are not limited to, the following, any one or more of which could materially affect the outcome of future events:

These factors should not be construed as exhaustive. Additional information on these and other risk factors can be found in Part I. Item 1A. “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the Company’s Annual Report and in Part II. Item 1A. “Risk Factors” of this report.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on any forward-looking statement as a prediction of future events. We expressly disclaim any obligation or undertaking to update our forward-looking statements, and we do not intend to release publicly any updates or changes in our expectations concerning the forward-looking statements or any changes in events, conditions or circumstances upon which any forward-looking statement may be based, except as required by law.

Company Overview

This section presents management’s perspective on the consolidated financial condition and results of operations of the Company and its wholly-owned subsidiary, the Bank. The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and related notes thereto included herein, and the audited consolidated financial statements for the year ended December 31, 2025, including the notes thereto, and the related MD&A in the Annual Report. All cross-references to the “Notes” in this Form 10-Q refer to the Notes to Consolidated Financial Statements contained in Part I. Item 1. Financial Statements unless otherwise noted.

The Bank commenced operations in 2006, and we completed our initial public offering in July 2014. On July 1, 2019, the Bank changed from a Louisiana state bank charter to a national bank charter, and its name changed to Investar Bank, National Association. Through the Bank, we provide full banking services, excluding trust services, tailored primarily to meet the needs of individuals, professionals, and small to medium-sized businesses. Our primary areas of operation are south Louisiana, including Baton Rouge, New Orleans, Lafayette, Lake Charles, and their surrounding areas; Texas, including Houston and its surrounding area, and, as of January 1, 2026, north Dallas and Wichita Falls and their surrounding areas; and Alabama, including York and Oxford and their surrounding areas. At June 30, 2026, we operated 36 full service branches comprised of 20 full service branches in Louisiana, ten full service branches in Texas, and six full service branches in Alabama.

Our strategy focuses on consistent, quality earnings through the optimization of our balance sheet. Our strategy includes originating and renewing high quality, primarily variable-rate, loans and allowing higher risk credit relationships to run off. We have kept duration short on our liabilities to provide flexibility to secure lower cost funding that was accretive to our net interest margin. Our strategy also includes growth through acquisitions, including whole-bank acquisitions, strategic branch acquisitions and asset acquisitions. We have completed eight whole-bank acquisitions since 2011 and regularly review acquisition opportunities. Our most recent whole bank acquisition was completed in January 2026. For additional information, see “Acquisition of WFB” below.

Our principal business is lending to and accepting deposits from individuals and small to medium-sized businesses in our areas of operation. As a financial holding company operating through one reportable segment, we generate our income principally from interest on loans and, to a lesser extent, our securities investments, as well as from fees charged in connection with our various loan and deposit services. Our principal expenses are interest expense on interest-bearing customer deposits and borrowings, salaries and employee benefits, occupancy costs, data processing and other operating expenses. We measure our performance through our net interest margin, return on average assets, and return on average equity, among other metrics, while seeking to maintain appropriate regulatory leverage and risk-based capital ratios.

Acquisition of WFB

On July 1, 2025, we announced that we had entered into the Agreement and Plan of Merger by and between the Company and WFB, headquartered in Wichita Falls, Texas, which provided for the merger of WFB with and into the Company, with the Company as the surviving corporation, followed by the merger of FNB, WFB’s wholly-owned subsidiary, with and into the Bank, with the Bank as the surviving bank. We completed the acquisition of WFB and FNB on January 1, 2026. All of the issued and outstanding shares of WFB common stock were converted into aggregate merger consideration consisting of $7.2 million in cash and 3,955,272 shares of our common stock for an aggregate transaction value of $112.9 million. This value is based on the Company’s closing stock price on December 31, 2025 of $26.72 per common share. On January 1, 2026, we acquired $1.15 billion in total assets, $950.2 million in net loans and $1.02 billion in total deposits. For additional i

Overview

The Bank commenced operations in 2006 and we completed our initial public offering in July 2014. On July 1, 2019, the Bank changed from a Louisiana state bank charter to a national bank charter and its name changed to Investar Bank, National Association. Through the Bank, we provide full banking services, excluding trust services, tailored primarily to meet the needs of individuals, professionals, and small to medium-sized businesses. Our primary areas of operation are south Louisiana (approximately 77% of our total deposits as of December 31, 2025), including Baton Rouge, New Orleans, Lafayette, Lake Charles, and their surrounding areas; Texas, including Houston and its surrounding area, and, as of January 1, 2026, north Dallas and Wichita Falls and their surrounding areas; and Alabama, including York and Oxford and their surrounding areas. As of March 16, 2026, we operated 36 full-service branches comprised of 20 full-service branches in Louisiana, ten full-service branches in Texas, and six full-service branches in Alabama.

Our principal business is lending to and accepting deposits from individuals and small to medium-sized businesses in our areas of operation. As a financial holding company operating through one reportable segment, we generate our income principally from interest on loans and, to a lesser extent, our securities investments, as well as from fees charged in connection with our various loan and deposit services.

Acquisition of WFB

On July 1, 2025, we announced that we had entered into the Agreement and Plan of Merger by and between Investar and WFB, headquartered in Wichita Falls, Texas, which provided for the merger of WFB with and into Investar, with Investar as the surviving corporation, followed by the merger of FNB, WFB’s wholly-owned subsidiary, with and into the Bank, with the Bank as the surviving bank. The Company completed its acquisition of WFB and FNB on January 1, 2026. All of the issued and outstanding shares of WFB common stock were converted into aggregate merger consideration consisting of $7.2 million in cash and 3,955,272 shares of Company common stock for an aggregate transaction value of $112.9 million. This value is based on the Company’s closing stock price on December 31, 2025 of $26.72 per common share. At December 31, 2025, WFB had $1.2 billion in total assets, $1.0 billion in net loans and $1.0 billion in total deposits.

Private Placement of Series A Preferred Stock

In connection with the WFB transaction, on July 1, 2025, we completed a private placement of 32,500 shares of our newly designated Series A Preferred Stock with selected institutional and other accredited investors at a price of $1,000 per share, for aggregate gross proceeds of $32.5 million. The net proceeds were $30.4 million, after deducting placement agent fees and other offering-related expenses. Investar utilized the net proceeds from the offering to support the acquisition of WFB and for general corporate purposes, including organic growth and other potential acquisitions. For additional information, see Note 13. Stockholders’ Equity.

For certain GAAP performance measures, see “Certain Performance Indicators: GAAP Financial Measures” below. We also monitor changes in our tangible equity, tangible assets, and tangible book value per common share, shown in the section “Certain Performance Indicators: Non-GAAP Financial Measures” below.

Certain Performance Indicators: GAAP Financial Measures

Certain Performance Indicators: Non-GAAP Financial Measures

Our accounting and reporting policies conform to accounting principles generally accepted in the United States, or GAAP, and the prevailing practices in the banking industry. However, we also evaluate our performance based on certain additional non-GAAP metrics, including tangible book value, tangible assets, tangible book value per common share, and tangible common equity to tangible assets. These measures are not financial measures recognized under GAAP and, therefore, are considered non-GAAP financial measures.

Table of Contents

Our management, banking regulators, financial analysts and investors use these non-GAAP financial measures to compare the capital adequacy of banking organizations with significant amounts of preferred stock and/or goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions. Tangible equity, tangible assets, tangible book value per common share or related measures should not be considered in isolation or as a substitute for total stockholders’ equity, total assets, book value per common share or any other measure calculated in accordance with GAAP. Moreover, the manner in which we calculate tangible equity, tangible assets, tangible book value per common share and any other related measures may differ from that of other companies reporting measures with similar names. The following table reconciles, as of the dates set forth below, stockholders’ equity (on a GAAP basis) to tangible equity and total assets (on a GAAP basis) to tangible assets and calculates our tangible book value per common share (dollars in thousands).
