SUNNYVALE, Calif.–(BUSINESS WIRE)–July 31, 2007–MoSys, Inc.
(MoSys), (NASDAQ: MOSY), the industry’s leading provider of
high-density system-on-chip (SoC) embedded memory intellectual
property (IP), today reported financial results for its second quarter
ended June 30, 2007.

Second Quarter Highlights

Total revenue for the second quarter of 2007 was $4.3 million,
representing a 38 percent increase compared to $3.1 million in the
first quarter of 2007. Second quarter total revenue increased 85
percent as compared to $2.3 million for the second quarter of 2006.

Second quarter total revenue included $2.1 million of licensing
revenue as compared to $1.1 million in the first quarter of 2007,
representing a sequential increase of 86 percent, and $1.7 million in
the second quarter of 2006. Royalty revenue was $2.2 million as
compared to $2.0 million in the previous quarter and $639,000 in the
same period a year ago. The Company recorded licensing revenue from 14
different chip development projects compared to 12 projects in the
previous quarter, and royalty revenue from 16 different licensees,
which was consistent with the previous quarter.

The second quarter gross margin percentage determined in
accordance with U.S. generally accepted accounting principles (GAAP)
was 84 percent as compared to 82 percent in the first quarter of 2007
and 84 percent in the second quarter of 2006.

Total operating expenses were $4.9 million as compared to $4.7
million in the first quarter of 2007.

On a GAAP basis, net loss for the quarter was $146,000, or
breakeven per share, including stock-based compensation charges of
$794,000. This compares to a net loss of $969,000, or ($0.03) per
share, in the previous quarter and a net loss of $2.1 million, or
($0.07) per share, in the second quarter of 2006. Earnings per share
for the quarter on a GAAP basis were computed using 31,945,000 shares.

The non-GAAP net income for the second quarter of 2007, which
excludes the total stock-based compensation charges of $794,000, was
$648,000, or $0.02 fully diluted per share. Net income per share for
the quarter on a non-GAAP basis was computed using 32,882,000 shares.
A reconciliation of GAAP results to non-GAAP results is provided in
the financial statement tables following the text of this press

Cash, cash equivalents and long and short-term investments totaled
approximately $87.6 million as of June 30, 2007, an increase from the
approximately $84.3 million as of December 31, 2006.

“During the second quarter, we signed another Technology License
agreement for our 1T-SRAM(R) at an advanced process node. This
agreement will enable NEC Electronics (NEC) to incorporate our 1T-SRAM
technology onto their 55nm process for use in chip implementations
targeting next-generation consumer, graphics and networking
applications,” stated Chet Silvestri, CEO of MoSys, Inc. “This
agreement aligns with our strategy to sign technology license
agreements with major semiconductor manufacturers at the most advanced
process nodes and is further evidence of the scalability of our
technology. In addition to our technology license progress, we are
pleased with the growth in royalties that we are achieving due to the
incorporation of our 1T-SRAM technology into the Nintendo Wii game
console. The success of this game console is contributing to
quarter-over-quarter growth in royalty revenues and increasing the
visibility of our 1T-SRAM technology in the marketplace.”

“With respect to our other major technology initiative, we
announced the tape-out of our first 1T-FLASH(TM) memory macro during
the quarter. This macro completes an important milestone in our first
customer licensing agreement and signals the beginning of our market
roll-out of this technology to other customers,” continued Mr.

Mr. Silvestri continued, “In another important milestone for the
quarter, we announced the acquisition of a number of Mixed Signal chip
designs from Atmel Corporation. One of these chip designs is an Analog
Front End (AFE) targeted at the High Definition/Blue Ray DVD market.
Another chip design is an 8 port Gigabit Switch, which is targeted at
the networking market. These product acquisitions support our strategy
to further penetrate the high-volume consumer multimedia and
networking markets and complements our 1T-SRAM and 1T-FLASH(TM) memory
IP offerings. By expanding our technology portfolio with these
products, we can offer our licensees a more complete set of IP to
support their system solutions.”

Use of Non-GAAP Financial Measures

To supplement MoSys’ consolidated financial statements presented
in accordance with GAAP, MoSys uses non-GAAP financial measures that
exclude from the statement of operations the effects of stock-based
compensation and the effects of our adoption of Statement of Financial
Accounting Standard No. 123R (SFAS 123R) upon the number of shares
used in calculating non-GAAP loss per share. MoSys management uses the
above non-GAAP financial measures internally to understand, manage and
evaluate our business. MoSys believes it is useful for itself and
investors to review, as applicable, both GAAP information and the
non-GAAP measures, which exclude the effects of stock-based
compensation and the effects of our adoption of Statement of SFAS
123R, in order to assess the performance of our continuing operations
and for planning and forecasting in future periods. The presentation
of these non-GAAP measures is intended to provide investors with an
understanding of our operational results and trends that enables them
to analyze our base financial and operating performance and facilitate
period-to-period comparisons and analysis of operational trends. MoSys
believes the presentation of these non-GAAP financial measures is
useful to investors in allowing for greater transparency with respect
to supplemental information used by management in its financial and
operational decision-making.

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. 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 July
31, 2007 that we have submitted to the Securities and Exchange
