Exhibit 99.1 Fixed Income Investor Presentation

Forward-Looking Statements and Financial Information This presentation
may contain various statements about Renasant Corporation (“Renasant,” “RNST”, “the Company,” “we,” “our,” or “us”) that constitute “forward-looking statements”
within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements preceded by, followed by or that otherwise include the words “believes,”
“expects,” “projects,” “anticipates,” “intends,” “estimates,” “plans,” “potential,” “focus,” “possible,” “may increase,”
“may fluctuate,” “will likely result,” or similar expressions, or future or conditional verbs such as “will,” “should,” “would” and “could,” are generally forward-looking in
nature and not historical facts. Forward-looking statements include information about our future financial performance, business strategy, projected plans and objectives and are based on the current beliefs and expectations of management. We believe
these forward-looking statements are reasonable, but they are all inherently subject to significant business, economic and competitive risks and uncertainties, many of which are beyond our control. In addition, these forward-looking statements are
subject to assumptions about future business strategies and decisions that are subject to change. Actual results may differ from those indicated or implied in the forward-looking statements; such differences may be material. Prospective investors
are cautioned that any forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Investors should not place undue reliance on these forward-looking statements, which speak only as of the date they are
made. Management believes that the assumptions underlying our forward-looking statements are reasonable, but any of the assumptions could prove to be inaccurate. Investors are urged to carefully consider the risks described in Renasant’s
filings with the Securities and Exchange Commission (“SEC”) from time to time, including its most recent Annual Report on Form 10-K and other documents filed by the Company with the SEC, which are available at www.renasant.com and the
SEC’s website at www.sec.gov. We undertake no obligation, and specifically disclaim any obligation, to update or revise our forward-looking statements, whether as a result of new information or to reflect changed assumptions, the occurrence of
unanticipated events or changes to future operating results over time, except as required by federal securities laws. Preliminary Financial Information This presentation includes certain preliminary unaudited financial information and expectations
relating to the first quarter of 2026. Our full unaudited financial statements as of and for the three months ended March 31, 2026, are not yet available. In the opinion of management, such unaudited financial information includes all adjustments
(consisting of normal recurring accruals) necessary for a fair presentation of our financial position and results of operations for such period. These results are also subject to further revision based upon the review of our independent auditors of
such quarterly results and an audit by our independent auditors of our annual results for the year ended December 31, 2026. Therefore, no assurance can be given that, upon completion of our review and the review of our independent auditors, we will
not report materially different financial results than those set forth in this presentation. We cannot assure you that such results will be indicative of our results for the entire year ending December 31, 2026. We do not intend to update or
otherwise revise these expected events and estimates to reflect future events or changes in estimates and do not intend to disclose publicly whether our actual results will vary from our estimates other than through the release of actual results in
the ordinary course of business. No independent public accounting firm has compiled, examined or performed any procedures with respect to the preliminary financial information included in this presentation, nor have they expressed any opinion or
other form of assurance on such information or its achievability. These estimates should not be regarded as a representation by us, our management or the underwriters as to our actual results for the first quarter of 2026. The assumptions and
estimates underlying the estimated financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties, including those described under “Risk Factors”
and “Cautionary Note Regarding Forward-Looking Statements” in our SEC filings. Accordingly, you should not place undue reliance on these estimates. 2

Non-GAAP Financial Measures and Disclaimer Non-GAAP Financial Measures
This presentation contains financial measures determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). The Company’s management believes that these non-GAAP
financial measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Company’s
management believes these non-GAAP financial measures facilitate the making of period-to-period comparisons and are meaningful indicators of its operating performance, particularly because these measures are widely used by industry analysts for
companies with merger and acquisition activities. You should not rely on these non-GAAP financial measures as a substitute for, or as superior to, GAAP results. Non-GAAP financial measures have inherent limitations, are not uniformly applied and are
not audited. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. For a reconciliation of these
non-GAAP financial measures to their most directly comparable GAAP measures, see the Appendix. Disclaimer This presentation is not an offer to sell securities, and the Company is not soliciting an offer to buy securities in any jurisdiction where
such offer or sale is not permitted. Neither the SEC, Federal Deposit Insurance Corporation ( FDIC ), nor any state securities commission has approved or disapproved of the securities of the Company or passed upon the accuracy or adequacy of this
presentation. Any representation to the contrary is a criminal offense. Certain information contained in this presentation related to or is based on publications and other data obtained from third-party sources. While the Company believes these
third-party sources to be reliable as of the date of this presentation, the Company has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party
sources. The delivery of this presentation shall not, under any circumstances, create any implication that there has been no change in the affairs of the Company after the date hereof. 3
