    SAN MATEO, Calif.--(BUSINESS WIRE)--Jan. 30, 2007--Keynote Systems
(Nasdaq: KEYN), The Mobile and Internet Performance Authority(TM),
today announced financial results for its fiscal first quarter ended
December 31, 2006.

    Umang Gupta, chairman and CEO of Keynote, said: "Solid execution,
particularly by Keynote SIGOS, delivered strong first quarter results.
Our Internet Test and Measurement and Customer Experience Test and
Measurement (CEM) businesses together performed in line with company
expectations, while our Mobile Test and Measurement business exceeded
projections. Mobile Test and Measurement revenue grew to $3.2 million,
or 33 percent sequentially, and net deferred revenue, the majority of
which is related to Keynote SIGOS, grew to $14.7 million or 38 percent
sequentially. We believe the increase in both reported revenue and
deferred revenue provides a comprehensive indicator of our growth."

    Gupta continued, "Keynote is capitalizing on opportunities
presented by the rapidly evolving mobile and Internet markets. The
better than expected top-line results from Keynote SIGOS combined with
operating cost controls drove improved margins earlier than expected.
Providing that Keynote SIGOS continues to perform for the remainder of
the fiscal year 2007 at the same level as last year, we expect to
deliver non-GAAP net income throughout fiscal 2007."

    First Quarter 2007 Financial Summary

    Revenue for the first quarter of fiscal year 2007 was $15.8
million, an increase of four percent compared to the preceding quarter
and a 15 percent increase compared to the first quarter of fiscal year
2006. Net income for the first quarter of fiscal year 2007, which
included a $1.0 million income tax benefit, $920,000 in stock-based
compensation expenses, and a $759,000 charge for amortization of
intangible assets required under generally accepted accounting
principles (GAAP), was $264,000, or $0.01 per diluted share. This
compared to net loss of $6.0 million, or $0.35 per share, for the
preceding quarter, and net income of $587,000, or $0.03 per diluted
share, for the first quarter a year ago.

    The non-GAAP net income for the quarter was $551,000, or $0.03 per
diluted share, compared to non-GAAP net loss of $797,000, or $0.05 per
share, for the preceding quarter, and non-GAAP net income of $2.4
million, or $0.12 per diluted share, for the first quarter a year ago.
The company defines non-GAAP net income or loss as net income or loss
adjusted for provision for income taxes, less cash tax expense,
stock-based compensation expense, amortization of purchased
intangibles. Non-GAAP net income per share equals non-GAAP net income
divided by the weighted diluted share count as of that period end.
Non-GAAP net loss per share equals non-GAAP net loss divided by the
weighted basic share count as of that period end.

    Cash, Free Cash Flow and Deferred Revenue Summary

    Keynote SIGOS' revenue recognition policy under GAAP requires the
amortization of most of Keynote SIGOS' software license revenues over
an approximate twenty-four month period. Although Keynote had a
consolidated GAAP and non-GAAP net loss for each of the past two
quarters, Keynote SIGOS' strong revenue growth has resulted in earlier
than expected consolidated non-GAAP income in the current quarter. In
addition, until Keynote SIGOS' revenues normalize with quarterly
billings, management believes cash provided by operating activities,
free cash flow and deferred revenue are also important metrics to
measure and manage Keynote's financial performance.

    For the quarter, cash provided by operating activities was $5.1
million, compared to $1.2 million in the prior quarter and $3.7
million in the first quarter of 2006. Cash used for purchases of
property, equipment and software totaled $1.1 million for the first
quarter of 2007, compared to $874,000 in the prior quarter and
$549,000 for the same period last year. Keynote generated free cash
flow, defined as cash flow from operations less cash used for
purchases of property, equipment, and software, of $4.0 million for
the quarter, compared to $357,000 in the prior quarter and $3.2
million for the same period last year.

    Keynote's net deferred revenue was $14.7 million at December 31,
2006, up 38 percent compared to $10.6 million at September 30, 2006
and up 144 percent from $6.0 million at December 31, 2005. The
increase resulted primarily from the amortization of Keynote SIGOS
revenue over the life of customer contracts. Keynote's gross deferred
revenue, defined as the sum of net deferred revenue and unpaid
deferred revenue of $8.9 million, increased to $23.6 million at
December 31, 2006, up 83 percent compared to $12.9 million at
September 30, 2006.

    "Our deferred revenues and cash from operations are at an all time
high with strong contribution from Keynote SIGOS," said Gupta. "This,
again, proves our continued success nurturing the synergies of the
acquisition and solidifies our position as a major player in the fast
growing mobile test and measurement industry."

    The company had $95.6 million in total cash, cash equivalents and
short-term investments as of December 31, 2006, of which approximately
$10.6 million is expected to be paid in the second fiscal quarter as a
performance earn-out to SIGOS' shareholders under the terms of the
purchase agreement for the acquisition of SIGOS by Keynote.

    Operational Metrics Summary

    As of December 31, 2006, Keynote's total worldwide customer base
was approximately 2,650 companies, up from approximately 2,300
customers in the same quarter a year ago. Keynote currently provides
its services to 70 percent of the comScore Media Metrix's top 50 Web
sites and approximately half of the Fortune 100 companies. As of
December 31, 2006, Keynote measured over 10,000 Internet pages, as
compared to 9,000 Internet pages in the same quarter a year ago.

    Expectations for the Second Quarter of Fiscal Year 2007

    The following company outlook for the second quarter of fiscal
2007 also includes expectations for Keynote SIGOS. The company
consolidated Keynote SIGOS' financial reporting under U.S. GAAP rules
starting April 3, 2006. U.S. GAAP requires Keynote SIGOS' system
license revenue to be ratably recognized over the initial duration of
each customer contract, which averages approximately twenty-four
months.

    As a result of the aforementioned accounting, Keynote will be able
to recognize as revenues only a fraction of Keynote SIGOS sales during
fiscal 2007. Accordingly, the acquisition will be dilutive to
Keynote's U.S. GAAP net income, although cash flow from operations is
expected to be positive.

    The statements in this section of this press release are
forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. Keynote currently expects the following for the second fiscal
quarter ending March 31, 2007:

    --  Total revenue is expected to be between $16.2 million and
        $16.7 million.

    --  Net earnings (loss) per share are expected to be between
        $(0.02) and $0.02.

    --  Non-GAAP earnings per share are expected to be between $0.05
        and $0.08.

    --  Cash provided by operating activities is expected to be
        between $3.0 million and $3.5 million.

    --  Free cash flow is expected to be between $2.0 million and $2.5
        million.

    The above guidance was based on the following assumptions. Total
stock-based compensation expense and amortization of intangible assets
is expected to be approximately $1.8 million. Interest income, net is
expected to be approximately $1.0 million, assuming no material
changes in interest rates. Cash paid for income taxes is expected to
be approximately $400,000. As noted, cash paid to SIGOS' shareholders
for acquisition related performance fees is expected to be
approximately $10.6 million. Basic weighted average shares outstanding
are expected to be approximately 17.1 million shares and diluted
weighted average shares outstanding are expected to be approximately
17.7 million shares.
