United Community Banks (UCB) S-4/A Registration of securities issued in business combination transactions (amended)

Exhibit 99.2​

July [•], 2015

Dear Palmetto Shareholder:

In connection with the proposed merger of Palmetto Bancshares, Inc. (“Palmetto”) with and into United Community Banks, Inc. (“United”), we are pleased to offer you the opportunity to indicate your preference as to the form of consideration you will receive for your shares of Palmetto common stock. Subject to the proration provisions of the merger agreement described below (which may result in adjustments to your election), you have the right to elect to receive, for each share of Palmetto common stock that you own, either 0.97 shares of United common stock, with cash paid in lieu of fractional share interests (the “stock consideration”), or $19.25 in cash (the “cash consideration”). You may specify different elections with respect to different shares that you hold (if, for example, you hold l00 shares of Palmetto common stock, you can make a stock election with respect to 50 shares and a cash election with respect to 50 shares). For the stock consideration, the amount of cash to be paid in lieu of each fractional share interest will be an amount equal to such fractional part of a share of United common stock multiplied by the average of the closing sale prices of United common stock as reported on the NASDAQ Global Select Market during the 20 consecutive full trading days ending at the closing of trading on the trading day immediately prior to the later of  (i) the effective date of the last required consent of any regulatory authority having authority over and approving or exempting the merger and (ii) the date of the receipt of the approval of the Palmetto shareholders to the merger.

Because the exchange ratio for the stock consideration is fixed at 0.97 Unitedshares for each Palmetto share, the value of the stock consideration will fluctuate with the market price of Unitedcommon stock. Accordingly, at the time of the merger, the per share value of the stock consideration may be greater or lesser than the per share value of the cash consideration. On July [•], 2015, the closing price of Unitedcommon stock was $[•], making the value of 0.97 shares of Unitedcommon stock equal to $[•] on that date, as compared to $19.25 for the cash consideration. You should obtain a current price quotation for Unitedcommon stock. Unitedcommon stock trades on the NASDAQ Global Select Market under the symbol “UCBI.” Please note that if you hold your Palmetto shares through a bank, broker or other nominee, the stock and/or cash consideration you are entitled to receive in the merger will be paid to your bank, broker or other nominee first, and then distributed to you in accordance with their procedures.

The merger agreement provides that 70% of the shares of Palmetto common stock outstanding immediately prior to the effective time of the merger will be exchanged for the stock consideration, with the remaining 30% of the outstanding Palmetto shares exchanged for the cash consideration. As a result, if the holders of more than 70% of the outstanding Palmetto shares make valid elections to receive the stock consideration or if the holders of more than 30% of the outstanding Palmetto shares make valid elections to receive the cash consideration, those Palmetto shareholders electing the over-subscribed form of consideration will have the over-subscribed form of consideration proportionately reduced and will receive a portion of their consideration in the other form, despite their election. Therefore, you might receive United stock and/or cash in an amount that is not consistent with your election, depending upon the elections of other Palmetto shareholders. For a description of the proration provisions of the merger agreement, see “Summary – The Merger Agreement” beginning on page 4 of the proxy statement-prospectus for the merger which was mailed separately to Palmetto shareholders on or about July [•], 2015.

Because the federal income tax consequences of the merger to you will depend on whether you receive stock, cash or a combination of both, you are urged to consult your personal tax advisor prior to making your election.

Enclosed is a Stock/Cash Election Form and Letter of Transmittal, which you must complete, sign and return with your Palmetto stock certificate(s) to the exchange agent for the merger, Continental Stock Transfer & Trust Company, in order to make an election. Please use the enclosed envelope to return your Stock/Cash Election Form and Letter of Transmittal and your stock certificate(s). For your election to be effective, the exchange agent must receive your Stock/Cash Election Form and Letter of Transmittal, together with any Palmetto stock certificate(s) (or a Notice of Guaranteed Delivery, as described in Instruction 15 to the Stock/Cash Election Form and Letter of Transmittal), NO LATER THAN 5:00 P.M., EASTERN TIME, ON AUGUST 12, 2015. Please follow the instructions on the Stock/Cash Election Form and Letter of Transmittal carefully. You do not need to sign the back of your Palmetto stock certificate(s). You may change or revoke your election at any time prior to the election deadline by following the instructions in the Stock/Cash Election Form and Letter of Transmittal.

If you hold any Palmetto shares through a bank, broker or other nominee, you will instead need to follow the instructions of the bank, broker or other nominee to make your election. Be sure to follow the instructions of your bank, broker or other nominee carefully, as they may impose an earlier election deadline and/or procedures different from those described above. You should contact your bank, broker or other nominee if you have any questions regarding their instructions.

If you need assistance, please contact Jan Heaton, United Shareholder Relations, at 706-781-2265or Lauren Greer, Director – Finance and Accounting of Palmetto, at 864-250-6050. If you do not make a timely and proper election, the exchange agent will send you additional forms for the surrender of your Palmetto stock certificate(s) after completion of the merger, and you will receive Unitedcommon stock and/or cash in exchange for your shares depending on the timely and proper elections of other Palmetto stockholders pursuant to the allocation provisions of the merger agreement.

Your submission of a Stock/Cash Election Form and Letter of Transmittal does NOT constitute a vote on the merger agreement. In order to vote your Palmetto shares on the merger agreement, you must complete, sign, date and return the proxy card included with the proxy statement-prospectus previously mailed to you, or attend the special meeting of Palmetto shareholders described in the proxy statement-prospectus and vote in person at the meeting.

ELECTION OPTIONS: On page 3 of this Stock/Cash Election Form and Letter of Transmittal, you may indicate whether you would like to receive, in exchange for your shares of Palmetto common stock, the stock consideration, the cash consideration or a combination of the stock consideration and the cash consideration. Alternatively, you may indicate that you have no preference as to the form of merger consideration that you will receive. Mark only one selection. The Merger Agreement provides that 70% of the shares of Palmetto common stock outstanding immediately prior to the effective time of the merger will be exchanged for the stock consideration, with the remaining 30% of the outstanding Palmetto shares exchanged for the cash consideration. Therefore, you might receive United stock and/or cash in an amount that is not consistent with your election, depending upon the elections of other Palmetto shareholders. Palmetto shareholders who are deemed to have made a non-election will receive all cash, unless cash has been fully subscribed by the electing Palmetto shareholders, in which event such Palmetto shareholders will be treated as if they elected all stock.

4.

NOMINEES: Any record holder of shares of Palmetto common stock who is a nominee may submit one or more Stock/Cash Election Forms and Letters of Transmittal indicating on the form or forms a combination of elections covering up to the aggregate number of shares of Palmetto common stock owned by such record holder. However, upon the request of United, such record holders will be required to certify to the satisfaction of United that such record holder holds such shares of Palmetto common stock as nominee for the beneficial owners of such shares.

5.

REVOCATION OR CHANGE OF STOCK/CASH ELECTION FORM: Any Stock/Cash Election Form and Letter of Transmittal may be revoked or changed by written notice from the person submitting such form to the exchange agent for the merger, Continental Stock Transfer & Trust Company (the “Exchange Agent”), but to be effective, such notice must be received by the Exchange Agent at or prior to the Election Deadline. United will have the discretion, which it may delegate to the Exchange Agent, to determine whether any revocation or change is received on a timely basis and whether any such revocation or change has been properly made.

6.

SURRENDER OF CERTIFICATE(S): For any election contained herein to be effective, this Stock/​Cash Election Form and Letter of Transmittal must be accompanied by any certificate(s) evidencing your shares (or a Notice of Guaranteed Delivery - see Instruction 15) and any required accompanying evidences of authority (see Instruction 11).

7.

LOST CERTIFICATE(S): If the certificate(s) that a registered holder (or transferee) wants to surrender has (have) been lost or destroyed, that holder should promptly contact the transfer agent for Palmetto common stock, American Stock Transfer & Trust Company, LLC, at (800) 937-5449 to arrange

8.

PRIORITY FOR STOCK ELECTION OR MIXED ELECTION SHARES: If you have made a Stock Election or Mixed Election and acquired your Palmetto shares in different lots, you may designate on this Stock/Cash Election Form and Letter of Transmittal, by stock certificate number, one or more of such lots for priority allocation of any stock consideration which you are entitled to receive. The following is an example of how the priority allocation works. Assume you own 1,000 shares of Palmetto common stock, 200 of which you acquired in 2008, 300 of which you acquired in 2010 and 500 of which you acquiredin 2012. Assume further that you elect the stock consideration for all of your Palmettoshares and the number of stock elections by Palmetto shareholders exceeds the available stock consideration,such that, under the proration provisions of the merger agreement, 90% of your Palmetto shares will be converted to the stock consideration, with the remaining 10% converting to the cash consideration. By making a priority designation, you are designating the order (by stock certificate number/security listing number) in which your Palmetto shares are to be allocated the stock consideration under these circumstances. In the above example, if the order of your priority designation was: first, the shares acquired in 2012; second, the shares acquired in 2010; and third, the shares acquired in 2008, then all of the shares acquired in 2012 and 2010 would convert to the stock consideration and 100 of the shares acquired in 2008 would convert to the stock consideration and 100 would convert to the cash consideration. If you hold a single stock certificate that evidences shares of Palmetto common stock acquired in different lots and wish to make a priority designation, you should consult your personal tax advisor with regard to the method of identifying particular lots for priority allocation to the stock consideration.

No assurance can be made that you will receive the tax treatment that you desire as a result of making a priority designation on this Stock/Cash Election Form and Letter of Transmittal, and none of United, Palmetto, the Exchange Agent or any of their respective officers, directors, employees or agents assumes any responsibility for the tax treatment that you ultimately receive.
