Gartner, Inc. Announces Staff Reduction and Related Charge

STAMFORD, Conn.--Dec. 5, 2003--Gartner, Inc. (NYSE: IT and ITB), the world's
leading technology research and advisory firm, announced today that in an effort
to streamline operations, to strengthen key consulting practices, and to align
its organizational structure to client segments, the Company will eliminate
approximately 200 jobs or 5% of its global workforce. Gartner currently employs
approximately 3,800 people worldwide.

Gartner expects to record a charge of approximately $28 million-$32 million
related to the elimination of the positions. A portion of the charge will be
recognized in the fourth quarter ending December 31, 2003, with the balance to
be recognized in the first quarter ending March 31, 2004 as employees depart.
Other than the charge, the Company does not expect these actions to have an
effect on fourth quarter 2003 results.

Non-GAAP Financial Measures:

In this press release we refer to the term "normalized EPS". Normalized EPS is
not a financial measure under generally accepted accounting principles. In
addition, it should not be construed as an alternative to any other measures of
performance determined in accordance with generally accepted accounting
principles. This non-GAAP financial measure has been provided by us in our
earnings releases to enhance the reader's overall understanding of the Company's
current financial performance and the Company's prospects for the future. We
believe normalized EPS is an important measure of our recurring operations as it
excludes items that may not be indicative of our core operating results and
calculates earnings per share in a manner consistent with prior periods by
including the effect of debt conversion. Normalized EPS is based on net income,
excluding other charges, gains and losses on investments, and gains from the
sale of businesses. Normalized EPS includes the effect of the convertible debt
as if it had been converted as of the beginning of each period. This calculation
for periods during 2003 reflects the expectation that the convertible debt will
have a dilutive effect on EPS for the full year of 2003.
