Exhibit 99.1

The Palmetto Bank Announces Terms of Reverse Stock Split

A Component of Plans for Listing on the NASDAQ Stock Exchange

Greenville, S.C. – Palmetto Bancshares, Inc., the parent company of The Palmetto Bank, today announced that it filed an amendment to its Amended and Restated Articles of Incorporation with the Secretary of State of South Carolina to effect a 1-for-4 reverse stock split of its common stock. The reverse stock split will take effect at 11:59 p.m. on June 28, 2011 and will be effective with respect to shareholders of record at the close of business on that date (the “Effective Time”). As a result, at the Effective Time the Company’s 50.9 million outstanding shares of common stock will be reduced to 12.7 million. Fractional shares resulting from the reverse stock split for any individual shareholder will be rounded up to the next whole share. The reverse stock split will not have an impact on the overall economic value of the Company; however, since the reverse stock split will reduce the number of common shares outstanding it is expected to result in a corresponding increase in the bid price of the Company’s common stock.

The Company’s shares of common stock will continue to trade on the Pink OTC Markets, Inc. (the “Pink Sheets”) under the symbol “PLMT.PK” with the letter “D” added to the end of the trading symbol for a period of 20 trading days to indicate that the reverse stock split has occurred. Following the 20 day period, the ticker symbol will revert back to “PLMT.PK.” In addition, the Company’s shares of common stock will also trade under a new CUSIP number effective June 29, 2011. Shareholders of record as of the Effective Time will receive a letter of transmittal from the Company’s transfer agent with instructions regarding the exchange of their common stock certificates into new certificates reflecting the post-split shares owned.

As noted in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on April 14, 2011, the primary objective in effecting the reverse stock split is to raise the per share trading price of the Company’s common stock so as to achieve eligibility for listing on The NASDAQ Capital Market stock exchange. Under the terms of the Stock Purchase Agreement related to the Private Placement consummated on October 7, 2010, the Company is required to use its reasonable best efforts to list its common stock on NASDAQ or other national securities exchange. The Company previously filed an application for listing on the NASDAQ and believes that the only remaining requirement for the initial listing is to maintain a bid price of at least $4.00 per share.

“The completion of the reverse stock split is one of the final steps to listing our common stock on the NASDAQ stock exchange,” said Samuel L. Erwin, the Company’s Chief Executive Officer. “Becoming listed on NASDAQ is important to our existing shareholders to increase liquidity and visibility in our common stock. This is an important and exciting milestone in our Company’s 104 year history as we continue our efforts to generate long-term value for our shareholders.”
