Conversion Right Triggered on SBA Communications' 4.0% Convertible Senior
Notes (CUSIP# 78388JAM8)

BOCA RATON, Fla., April 15, 2013 (GLOBE NEWSWIRE) -- SBA Communications
Corporation (Nasdaq:SBAC) ("SBA") today announced that SBA's 4.0% Convertible
Senior Notes due 2014 (the "4.0% Notes") are convertible by holders of such
notes. Pursuant to the terms of the Indenture that governs the 4.0% Notes, SBA
has the right, from time to time, to elect to satisfy its conversion
obligation under the 4.0% Notes in shares of SBA's Class A common stock, cash
or a combination of SBA's Class A common stock and cash, and that election is
effective until SBA provides notice of a different method of settlement. Upon
issuance of the 4.0% Notes, SBA elected to settle such notes in shares of
SBA's Class A common stock and that election is still in effect.

The conversion right for the 4.0% Notes has been triggered because SBA's Class
A common stock closing price per share exceeded $39.49 for at least 20 trading
days during the 30 consecutive trading day period ending on March 31, 2013.
The 4.0% Notes will continue to be convertible until June 30, 2013, and may be
convertible thereafter, if one or more of the conversion conditions specified
in the Indenture, dated as of April 24, 2009, by and between SBA and U.S. Bank
National Association, is satisfied during future measurement periods.Pursuant
to Section 10.01 of the Indenture, a holder who elects to convert the 4.0%
Notes will receive 32.9164 shares of SBA's Class A common stock per $1,000
principal amount of notes.Pursuant to Section 10.02 of the Indenture, these
shares will be delivered 50 trading days after the holder delivers its notice
of conversion, unless a settlement period market disruption event (as defined
in the Indenture) occurs during this period.

U.S. Bank National Association is the Trustee for the holders of the 4.0%
Notes and is the Conversion Agent under the Indenture. All questions relating
to the mechanics of the conversion for the notes should be directed to Lori
Buckles at U.S. Bank National Association, telephone number: 651-495-3520 and
address: U.S. Bank, 60 Livingston Avenue, St. Paul, Minnesota, 55107.

This press release is only a summary of certain provisions of the 4.0% Notes
and the Indenture. A complete explanation of the conversion rights of holders
of the 4.0% Notes, as well as the procedures required to convert the 4.0%
Notes, is set forth in the Indenture. All holders are urged to review the
conversion provisions contained in the 4.0% Notes and the Indenture in its
entirety.
