2.02. Results

of Operations and Financial Condition.

April 15, 2026, Southern First Bancshares, Inc. (the “Company”) filed with the Securities and Exchange Commission (the “SEC”)

a preliminary prospectus supplement (the “Preliminary Prospectus Supplement”) in connection with an underwritten public offering

of shares of the Company’s common stock. The Preliminary Prospectus Supplement contains preliminary estimated unaudited financial

results of the Company as of and for the three months ended March 31, 2026. Such preliminary financial results are furnished under the

heading “Preliminary First Quarter 2026 Financial Information (Unaudited)” in the excerpt from the Preliminary Prospectus

Supplement filed as Exhibit 99.1 to this Current Report on Form 8-K.

The

preliminary financial results included in the Preliminary Prospectus Supplement are solely management estimates based on currently available

information, including internal management reports. In preparing the preliminary financial results, the Company’s management made

a number of complex and subjective judgments and estimates about the appropriateness of certain reported amounts and disclosures. The

Company’s actual financial results for the first quarter of 2026 have not yet been finalized. The preliminary financial results

are not a comprehensive statement of all financial results as of and for the three months ended March 31, 2026 and are not necessarily

indicative of the results to be achieved for any future period. The Company is required to consider all available information through

the finalization of its financial statements and their possible impact on the Company’s financial condition and results of operations

for the period, including the impact of such information on the complex judgments and estimates referred to above. As a result, subsequent

information or events may lead to material differences between the information about the results of operations described in the Preliminary

Prospectus Supplement and the results of operations described in the Company’s subsequent Quarterly Report on Form 10-Q. The Company’s

independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to, and does

not express an opinion or any other form of assurance on, the preliminary financial results.

The

information provided in this Item 2.02 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished

and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange

Act”), or otherwise subject to the liabilities of that section. The information in this Item 2.02 of this Current Report on Form

8-K, including Exhibit 99.1 attached hereto, shall not be incorporated by reference into any filing or other document pursuant to the

Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing

or document. The information furnished in this Item 2.02 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto,

shall not constitute an offer to sell or the solicitation of an offer to buy any securities.

Item

7.01. Regulation FD Disclosure.

April 15, 2026, the Company issued a press release announcing the commencement of an underwritten public offering of shares of the Company’s

common stock. A copy of the press release is furnished as Exhibit 99.2 to this Current Report on Form 8-K.

The

information provided in this Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.2 attached hereto, is being furnished

and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange

Act”), or otherwise subject to the liabilities of that section. The information in this Item 7.01 of this Current Report on Form

8-K, including Exhibit 99.2 attached hereto, shall not be incorporated by reference into any filing or other document pursuant to the

Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing

or document. The information furnished in this Item 7.01 of this

Current

Report on Form 8-K, including Exhibit 99.2 attached hereto, shall not constitute an offer to sell or the solicitation of an offer to

buy any securities.

Supplement and the accompanying prospectus and in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other reports filed

with the Securities and Exchange Commission. In addition, actual results for the three months ended March 31, 2026 may differ materially

from the preliminary financial information included in this Exhibit 99.1 as a result of the completion of our financial closing procedures,

Our

reviewed, compiled or performed any procedures with respect to this preliminary financial information and, accordingly, does not express

presentation of our financial results as of and for the three months ended March 31, 2026, and the final results as of and for the three

months ended March 31, 2026 may differ materially from the preliminary results set forth below. Accordingly, you should not place undue

reliance on this preliminary financial information. In addition, the estimates set forth below constitute forward-looking statements

and are subject to risks and uncertainties. These estimates should be read together with our Annual Report on Form 10-K and other filings

(4) The

preliminary financial information set forth in the table above reflects management’s

current estimates based solely on information available as of the date hereof and remains

subject to completion of financial closing procedures and other quarter-end review procedures.

Compared

to the quarter ended December 31, 2025, we expect:

● net

interest income and net interest margin to improve in the quarter ended March 31, 2026, reflecting

continued balance sheet repricing and lower funding costs, including an approximate 13 basis

point decline in the cost of total deposits from the quarter ended December 31, 2025; and

● noninterest

expense to increase on a linked-quarter basis, primarily due to seasonal increases in compensation

and benefits expense.

For

the quarter ended March 31, 2026 or as of March 31, 2026, as applicable, we also expect:

● net

income of approximately $9.9 million, as compared to $5.266 million for the quarter ended

March 31, 2025 (approximately +88% year-over-year);

● continued

balance sheet growth, with total loans of approximately $3.94 billion, total deposits of

approximately $3.87 billion and retail deposits of approximately $3.37 billion, representing

approximately 10% annualized loan growth, approximately 17% annualized total deposit growth

and approximately 27% annualized retail deposit growth from December 31, 2025;

● continued

solid asset quality, including nonperforming assets to total assets of approximately 0.26%

and annualized net charge-offs to average loans of approximately 0.01%; nonperforming asset

balances are expected to decline approximately 15% from December 31, 2025; and

● solid

capital levels, with tangible common equity to tangible assets, Tier 1 leverage ratio, common

equity Tier 1 capital ratio, Tier 1 risk-based capital ratio and total risk-based capital

ratio of approximately 8.3%, 9.1%, 11.0%, 11.4% and 12.8%, respectively.

Non-GAAP

Financial Measures

Tangible

common equity to tangible assets and efficiency ratio are non-GAAP financial measures. Tangible common equity to tangible assets is calculated

as total common equity less total intangible assets, divided by total assets less total intangible assets. Efficiency ratio is calculated

as total noninterest expense divided by total revenue, adjusted to exclude net gains on sale of securities. Management believes these

non-GAAP financial measures provide investors with useful supplemental information regarding the Company’s capital strength and

operating performance. These non-GAAP financial measures should not be considered in isolation or as substitutes for their most directly

comparable GAAP measures. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are set

forth below.

FORWARD-LOOKING STATEMENTS

Certain statements in this news release contain

“forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, such as statements

relating to the completion, timing and expected size of the offering, the anticipated closing date of the offering, the anticipated use

of proceeds from the offering, future plans and expectations, and are thus prospective. Such forward-looking statements are identified

by words such as “believe,” “expect,” “anticipate,” “estimate,” “preliminary”,

“intend,” “plan,” “target,” “continue,” “lasting,” and “project,”

as well as similar expressions. Such statements are subject to risks, uncertainties, and other factors which could cause actual results

to differ materially from future results expressed or implied by such forward-looking

statements. Although we believe that the assumptions

underlying the forward-looking statements are reasonable, any of the assumptions could prove to be inaccurate. Therefore, we can give

no assurance that the results contemplated in the forward-looking statements will be realized. The inclusion of forward-looking information

should not be construed as a representation by the Company or any other person that the future events, plans or expectations described

herein will be achieved.

The following factors, among others, could cause

actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1)

competitive pressures among depository and other financial institutions may increase significantly and have an effect on pricing, spending,

third-party relationships and revenues; (2) the strength of the United States economy in general and the strength of the local economies

in which the Company conducts operations may be different than expected; (3) the rate of delinquencies and amounts of charge-offs, the

level of allowance for credit loss, the rates of loan and deposit growth as well as pricing of each product, or adverse changes in asset

quality in our loan portfolio, which may result in increased credit risk-related losses and expenses; (4) changes in legislation, regulation,

policies or administrative practices, whether by judicial, governmental or legislative action, including, but not limited to, changes

affecting oversight of the financial services industry or consumer protection, the regulatory landscape or capital market; (5) adverse

conditions in the stock market, the public debt market and other capital markets (including changes in interest rate conditions) could

continue to have a negative impact on the Company, including the timing, size, pricing or completion of the offering; (6) changes in interest

rates, which may continue to affect the Company’s net income, interest expense, prepayment penalty income, mortgage banking income,

and other future cash flows, or the market value of the Company’s assets, including its investment securities; (7) trade wars, government

shutdowns, or a potential recession which may cause adverse risk to the overall economy, and could indirectly pose challenges to our clients

and to our business; (8) any increase in FDIC assessments which have increased and may continue to increase our cost of doing business;

and (9) changes in accounting principles, policies, practices, or guidelines. Additional factors that could cause our results to differ

materially from those described in the forward-looking statements can be found in our reports (such as Annual Reports on Form 10-K, Quarterly

Reports on Form 10-Q and Current Reports on Form 8-K) filed with the SEC and available at the SEC’s Internet site (www.sec.gov).

All subsequent written and oral forward-looking statements concerning the Company or any person acting on its behalf are expressly qualified

in their entirety by the cautionary statements above. We do not undertake any obligation to update any forward-looking statement to reflect

circumstances or events that occur after the date the forward-looking statements are made, except as required by law.
