Conversion Right Triggered on SBA Communications' 4.0% Convertible Senior
Notes (CUSIP# 78388JAM8) and 1.875% Convertible Senior Notes (CUSIP#
78388JAN6)

BOCA RATON, Fla., Jan. 2, 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") and SBA's 1.875% Convertible Senior
Notes due 2013 (the "1.875% Notes") are convertible by holders of such notes.
Pursuant to the terms of the Indentures that govern the 4.0% Notes and the
1.875% Notes, SBA has the right, from time to time, to elect to satisfy its
conversion obligation under the 4.0% Notes and the 1.875% 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 both the 4.0% Notes and the
1.875% Notes, SBA elected to settle such notes in shares of SBA's Class A
common stock and those elections are 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 December 31, 2012.
The 4.0% Notes will continue to be convertible until March 31, 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.

The conversion right for the 1.875% Notes has been triggered because SBA's
Class A common stock closing price per share exceeded $53.90 for at least 20
trading days during the 30 consecutive trading day period ending on December
31, 2012. The 1.875% Notes will continue to be convertible until March 31,
2013, and may be convertible thereafter, if one or more of the conversion
conditions specified in the Indenture, dated as of May 16, 2008, 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 1.875% Notes will receive 24.1196 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 both the 4.0%
Notes and the 1.875% Notes and the Conversion Agent under both Indentures. 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 1.875% Notes and the relevant Indentures. A complete explanation of
the conversion rights of holders of the 4.0% Notes and the 1.875% Notes, as
well as the procedures required to convert either the 4.0% Notes or the 1.875%
Notes, is set forth in the relevant Indenture. All holders are urged to review

applicable, and the relevant Indentures in their entirety.
