Management Commentary

“During the first quarter, we made further progress on the
execution of several key objectives,” stated Len Perham, MoSys’
President and Chief Executive Officer. “We added a vice president of
worldwide sales to our leadership team and initiated a direct sales
presence in Taiwan, China and Europe in support of our current
representatives already covering those regions.”

Mr. Perham continued, “As a result of recent efforts, we booked
our first major order for a display driver IC macro, which is based on
MoSys’ 1T-SRAM technology and designed specifically for high
resolution mobile handset displays. We also successfully demonstrated
our fully integrated SoC, which provides a single chip analog front
end (AFE) to potential partners who intend to provide Blu-ray quality
and resolution for PCs, DVD players and set top boxes. Our complex AFE
enables both Blu-ray BD and HD formats and is equipped with both read
and record functionality. This represents a tremendous accomplishment
and it opens a new market for our technology. With regard to 1T-FLASH,
we delivered our first 1T-FLASH production macro and are currently
assisting the customer with the integration of 1T-FLASH into their

“Looking forward, we remain optimistic about the Company’s future
prospects, as there are significant opportunities to leverage and
monetize our valuable IP. In the coming quarters, we expect to expand
and improve our relationships with our customers and foundry partners,
while exploring opportunities to increase our silicon content in SoCs.
Additionally, we will continue to strategically invest in R&D in order
to develop new technologies, particularly in Flash, as well as
evaluate strategic alternatives for accelerating the growth of our
business,” concluded Mr. Perham.

First Quarter Results

Total net revenue for the first quarter of 2008 was $2.8 million,
compared to $2.9 million for the fourth quarter of 2007 and $3.1
million for the first quarter of 2007.

First quarter total revenue included licensing revenue of $0.4
million, compared to $0.4 million for the fourth quarter of 2007 and
$1.2 million for the first quarter of 2007. Royalty revenue for the
first quarter was $2.4 million, which includes royalties associated
with the Nintendo Wii game console. First quarter royalty revenue
compares to $2.5 million for the previous quarter and $2.0 million for
the first quarter of 2007.

Gross margin as determined in accordance with U.S. Generally
Accepted Accounting Principles (GAAP) was 83 percent, compared to 72
percent for the fourth quarter of 2007 and 82 percent for the first
quarter of 2007.

Total operating expenses on a GAAP basis for the first quarter
were $7.7 million, which was consistent with the previous quarter and
compares to $4.7 million for the first quarter of 2007.

GAAP net loss for the quarter was $4.3 million, or ($0.14) per
share, including stock-based compensation expense of $1.3 million and
intangible asset amortization charges of $0.2 million. This compares
to a net loss of $4.6 million, or ($0.14) per share, for the fourth
quarter of 2007 and a net loss of $969,000, or ($0.03) per share, for
the first quarter of 2007.

The non-GAAP net loss for the first quarter was $2.8 million, or
($0.09) per share, excluding total stock-based compensation charges of
$1.3 million and $0.2 million in amortization charges. A
reconciliation of GAAP results to non-GAAP results is provided in the
financial statement tables following the text of this press release.

Earnings per share for the quarter on both a GAAP and non-GAAP
basis were computed using 31,673,000 shares.

Cash, cash equivalents and both long and short-term investments
totaled approximately $77.3 million as of March 31, 2008, compared to
approximately $78.7 million as of December 31, 2007.

Use of Non-GAAP Financial Measures

To supplement MoSys’ consolidated financial statements presented
in accordance with GAAP (U.S. Generally Accepted Accounting
Principles), MoSys uses non-GAAP financial measures that exclude from
the income statement the effects of stock-based compensation and the
effects of certain charges related to acquired intangible assets and
other acquisition-related charges from its acquisition of the
analog/mixed-signal design teams and their extensive related design
know-how from Atmel Corporation in 2007. MoSys’ management believes
that the presentation of these non-GAAP financial measures is useful
to investors and other interested persons because they are one of the
primary indicators that MoSys’ management uses for planning and
forecasting future performance. Mosys believes that the presentation
of non-GAAP financial measures that exclude these items is useful to
investors because Mosys does not consider these charges part of the
day-to-day business or reflective of the core operational activities
of the Company that are within the control of management or that would
be used to evaluate management’s operating performance.

Investors are encouraged to review the reconciliation of these
non-GAAP financial measures to the comparable GAAP results, which is
provided in a table immediately below the Condensed Consolidated
Statements of Operations. The non-GAAP financial measures disclosed by
the Company should not be considered a substitute for, or superior to,
financial measures calculated in accordance with GAAP, and the
financial results calculated in accordance with GAAP and
reconciliations to those financial statements should be carefully
evaluated. The non-GAAP financial measures used by the Company may be
calculated differently from, and therefore may not be comparable to,
similarly titled measures used by other companies. For additional
information regarding these non-GAAP financial measures, and
management’s explanation of why it considers such measures to be
useful, refer to the Form 8-K dated April 29, 2008, that the Company
filed with the Securities and Exchange Commission.
