ITEM 1. BUSINESS.
 
GENERAL
 
    NeoMagic Corporation (the "Company") was incorporated as a California
corporation in May 1993. The Company was subsequently reincorporated as a
Delaware corporation in February 1997. The Company's initial public offering
occurred in March 1997. The Company operates in one industry segment. NeoMagic
designs, develops and markets multimedia accelerators for sale to notebook PC
manufactures.
 
    Multimedia applications require the storage, processing and display of
enormous streams of data. As a result, multimedia PCs have evolved to
incorporate higher capacity storage and system memory, faster microprocessors,
improved specialized multimedia accelerators and higher quality displays.
However, due to the constraints imposed by the mobile form factor--the need for
low power consumption, small size, low weight, favorable thermal characteristics
and low cost, among others--the multimedia capabilities of notebook PCs have
historically lagged those of desktop computers. Until 1997, this limited the
effectiveness of multimedia applications in notebook PCs.
 
    To fully mobilize multimedia, the Company believed notebook PC manufacturers
required a new approach for developing multimedia accelerators which deliver
higher performance while minimizing power consumption, system size, weight,
complexity and cost.
 
    The Company, based on its knowledge of and experience in the industry,
believes it has developed the first commercially available high performance
silicon technology that integrates large DRAM memory with analog and logic
circuitry to provide multimedia solutions on a single chip. NeoMagic has
pioneered a new technology to provide multimedia semiconductor solutions for
notebook PCs which overcomes the limitations of traditional architectures. Using
this technology, the Company has developed its first product line: the
MagicGraph128 family of pin-compatible, multimedia (graphics, text and video)
accelerator products incorporating a 128-bit memory bus. These products provide
state-of-the art multimedia capability while decreasing power consumption, size,
weight, system design complexity and cost. The Company introduced its first
MagicGraph128 product in March 1995, and is currently in production with the
fourth generation of its MagicGraph128 product family.
 
    NeoMagic has established strategic relationships with Mitsubishi Electric
Corporation ("Mitsubishi Electric") and Toshiba Corporation ("Toshiba") to
produce semiconductor wafers for the Company's products. Pursuant to these
strategic relationships, NeoMagic designs the overall product, including the
logic and analog circuitry, and the manufacturing partners designs the DRAM
modules, manufactures the wafers and performs memory testing and repair.
NeoMagic is focused on leveraging its core competencies in logic, analog and
memory integration, graphics/video and other multimedia technologies, driver and
BIOS software, and power management in its continued development of solutions
that facilitate the mobilization of multimedia applications.
 
PRODUCTS
 
    The Company sells its products to notebook PC original equipment
manufacturers (OEMs) as well as to third-party subsystem manufacturers who
design and manufacture notebook PCs on behalf of the brand name OEMs. Sixteen of
the world's largest notebook PC manufacturers have designed or are designing
notebook PCs to include NeoMagic products. NeoMagic products are currently used
in notebook PCs sold by Acer, Compaq, Dell, Fujitsu, Gateway 2000,
Hewlett-Packard, Hitachi, IBM, Micron, Mitsubishi, NEC, Panasonic, Sharp,
Siemens, Sony, and Toshiba. NeoMagic sells its products either directly to these
companies or to subcontractors of such companies.
 
    Each product in the MagicGraph128 line of pin-compatible 128-bit multimedia
accelerators integrates large DRAM with analog and logic circuitry on a single
176-pin chip. NeoMagic's family of products range
 
                                       2
<PAGE>
from accelerators designed for notebook PCs that target cost-conscious consumers
to fully-featured multimedia systems designed for high-end notebook PCs. The
following table sets forth information with respect to each of the Company's
first five products:

*   Electro-Magnetic Interference
 
    MAGICGRAPH128.  The Company believes that the MagicGraph128, its first
product, is the industry's first 128-bit, single-chip graphics accelerator for
notebook computers. The MagicGraph128 provides high performance graphics for
mainstream business and consumer notebooks while decreasing power consumption,
size, system design complexity and cost.
 
    MAGICGRAPH128V.  The MagicGraph128V builds on the capabilities of the
MagicGraph128 by adding support for more colors and full-motion video. Optimized
for mobile business professionals who perform multimedia presentations with
sound and motion, the MagicGraph128V provides MPEG playback with full screen and
full motion video at 30 frames per second with true color.
 
    MAGICGRAPH128ZV.  The MagicGraph128ZV adds zoom video capability (for
capturing and displaying TV or video images) and television output capability to
the MagicGraph128V. The MagicGraph128ZV provides a fully-featured multimedia
solution for mid-range and high-end notebook PCs with 800x600 LCD displays.
 
    MAGICGRAPH128ZV+.  The MagicGraph128ZV+ provides a value-oriented multimedia
solution for entry level and ultra portable notebook computers. The
MagicGraph128ZV+ provides a Microsoft PC97 compliant feature set with 128bit
performance to the most cost conscious notebook computers.
 
    MAGICGRAPH128XD.  By offering higher display resolutions, a larger number of
displayable colors, and higher performance, the MagicGraph128XD is designed to
provide desktop-replacement capabilities to high-end notebooks. The
MagicGraph128XD is designed to deliver performance enhancements for Microsoft
Direct3D. These enhancements accelerate animation, games and business
applications utilizing 3D in a Windows environment.
 
RESEARCH AND DEVELOPMENT
 
    The Company considers the timely development and introduction of new
products to be essential to maintaining its competitive position and
capitalizing on market opportunities. Research and development efforts focus on
the design of new products and enhancements of existing ones that will help to
maintain or increase the Company's participation in various product areas. At
January 31, 1998, the Company had
 
                                       3
<PAGE>
approximately 91 employees engaged in research and development. Research and
development expenses in fiscal 1998, 1997 and 1996 were $16.1 million, $8.6
million and $4.9 million, respectively. The Company has made and intends to
continue to make significant investments in research and development to remain
competitive by developing new and enhanced products to serve its identified
markets. Research and development expenses are expected to increase in absolute
dollars in fiscal 1999. The development and successful introduction of new
products presents a variety of risks and there can be no assurance that these or
other product development efforts will be completed at the time the Company
expects, or that new products will be accepted in the marketplace.
 
SALES AND MARKETING
 
    NeoMagic's sales and marketing strategy is an integral part of the Company's
effort to become the leading supplier of multimedia accelerators to the leading
manufacturers of notebook PCs. To meet customer requirements and achieve design
wins, the Company's sales and marketing personnel work closely with its
customers, business partners and key industry trend setters to define product
features, performance, price, and market timing of new products. The Company
employs a sales force with a high level of technical expertise and product and
industry knowledge to support a lengthy and complex design win process.
Additionally, the Company employs a highly trained team of application engineers
to assist customers in designing, testing and qualifying system designs that
incorporate NeoMagic products. The Company believes that the depth and quality
of this design support are key to improving customers' time-to-market deliveries
and, maintaining a high level of customer satisfaction which encourages
customers to utilize subsequent generations of NeoMagic's products.
 
    In the United States, the Company sells its products to key customers
primarily through direct sales. In Japan, DIA Semicon acts as the Company's
sales representative. In Taiwan, Regulus acts as the Company's sales
representative, with support from the Company's Taiwan country manager. As of
January 31, 1998, NeoMagic employed 25 individuals in its sales, marketing and
support organization and maintained regional sales offices in Santa Clara,
California, Austin, Texas, Japan and Taiwan.
 
    In many cases, notebook PCs are designed and manufactured by third party
system manufacturers on behalf of the final brand name OEM. NeoMagic focuses on
developing long-term customer relationships with both the system manufacturer
and the brand name OEMs. The Company believes that this approach increases the
likelihood of design wins, improves the overall quality of support and enables
the timely release of customer products to market.
 
MANUFACTURING
 
    The Company's products require semiconductor wafers manufactured with
state-of-the-art fabrication equipment and technology. The Company's products
are designed to be manufactured in accordance with the DRAM partners' design
rules and manufacturing processes. Each DRAM partner has a design team dedicated
to NeoMagic product development. The DRAM partners designs the DRAM product
modules, and NeoMagic designs the overall product, including the analog and
logic circuitry. The DRAM partners then aids the Company in design verification
prior to production. The DRAM partners manufacture the wafers, perform memory
testing and repair, and sell the Company finished wafers, with pricing
determined on a quarterly basis. The Company uses subcontractors to perform
assembly, packaging and final test. The Company develops its own software and
hardware for product testing.
 
    NeoMagic has established strategic relationships with Mitsubishi Electric
and Toshiba to produce its semiconductor wafers and uses other independent
contractors to perform assembly, packaging and testing. The Company's
relationships with Mitsubishi Electric and Toshiba are formalized in separate
five year wafer supply agreements. These relationships enable the Company to
concentrate its resources on product design and development, where NeoMagic
believes it has greater competitive advantages, and to eliminate the high cost
of owning and operating a semiconductor wafer fabrication facility. The Company
depends
 
                                       4
<PAGE>
on these suppliers to allocate to the Company a portion of their manufacturing
capacity sufficient to meet the Company's needs, to produce products of
acceptable quality and at acceptable manufacturing yields and to deliver those
products to the Company on a timely basis. A manufacturing disruption
experienced by either of the Company's manufacturing partners would impact the
production of the Company's business, financial condition and results of
operations. Furthermore, in the event that the transition to the next generation
of manufacturing technologies at Mitsubishi Electric or Toshiba is unsuccessful
the Company's business, financial condition and results of operations would be
materially and adversely affected. Additionally, there can be no assurance that
either Mitsubishi Electric or Toshiba will continue to devote resources to the
production of the Company's products or continue to advance the process design
technologies on which the manufacturing of the Company's products are based. Any
such difficulties would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company's products are assembled and tested by third party
subcontractors. The Company does not have long-term agreements with any of these
subcontractors. As a result of this reliance on third party subcontractors to
assemble and test its products, the Company cannot directly control product
delivery schedules, which could lead to product shortages or quality assurance
problems that could increase the costs of manufacturing or assembly of the
Company's products. Due to the amount of time normally required to qualify
assembly and test subcontractors, if the Company is required to find alternative
subcontractors, shipments could be delayed significantly. Any problems
associated with the delivery, quality or cost of the assembly and test of the
Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
COMPETITION
 
    The market for multimedia accelerators for notebook PCs in which the Company
operates is intensely competitive and is characterized by rapid technological
change, evolving industry standards and declining average selling prices.
NeoMagic believes that the principal factors of competition in this market are
performance, price, features, power consumption, size and software support. The
ability of the Company to compete successfully in the rapidly evolving notebook
PC market depends on a number of factors, including success in designing and
subcontracting the manufacture of new products that implement new technologies,
product quality, reliability, price, the efficiency of production, design wins
for NeoMagic's integrated circuits, ramp up of production of the Company's
products for particular system manufacturers, end-user acceptance of the system
manufacturers' products, market acceptance of competitors' products and general
economic conditions. There can be no assurance that the Company will be able to
compete successfully in the future.
 
    NeoMagic competes with major domestic and international companies, some of
which have substantially greater financial and other resources than the Company
with which to pursue engineering, manufacturing, marketing and distribution of
their products. The Company's principal competitors include ATI ("ATI"), Chips &
Technologies, Inc. ("Chips & Technologies"-in January 1998, Intel Corporation
acquired Chips and Technologies.), S3 Incorporated ("S3") and Trident
Microsystems, Inc. ("Trident"). NeoMagic may also face increased competition
from new entrants into the notebook PC multimedia accelerator market including
companies currently selling products designed for desktop PCs. Furthermore, the
Company expects that many of its competitors will seek to develop and introduce
products that integrate large DRAM with analog and logic circuitry on a single
chip. For example, Chips & Technologies, Trident and S3 have announced that they
have or will begin sampling an integrated multimedia accelerator solution for
the notebook PC market that would directly compete with the Company's products.
Competition also exists from manufacturers that integrate a microprocessor with
a multimedia controller. Cyrix ("Cyrix" acquired by National Semiconductor in
July 1998) is in production with such a product. The successful commercial
introduction of a product by competitors that integrates large DRAM with analog
and logic circuitry on a single chip or a product that eliminates the need for a
separate multimedia
 
                                       5
<PAGE>
accelerator in notebook PCs could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
INTELLECTUAL PROPERTY
 
    The Company relies in part on patents to protect its intellectual property.
In the United States, the Company has been issued five patents, each covering
certain aspects of the design and architecture of the Company's multimedia
accelerators. In addition, the Company has patent applications pending in the
United States Patent and Trademark Office (the "PTO"). There can be no assurance
that the Company's pending patent applications or any future applications will
be approved, or that any issued patents will provide the Company with
competitive advantages or will not be challenged by third parties, or that the
patents of others will not have an adverse effect on the Company's ability to do
business. Furthermore, there can be no assurance that others will not
independently develop similar products, duplicate the Company's products or
design around any patents that may be issued to the Company.
 
    The Company also relies on a combination of mask work protection,
trademarks, copyrights, trade secret laws, employee and third-party
nondisclosure agreements and licensing arrangements to protect its intellectual
property. Despite these efforts, there can be no assurance that others will not
independently develop substantially equivalent intellectual property or
otherwise gain access to the Company's trade secrets or intellectual property or
disclose such intellectual property or trade secrets or that the Company can
meaningfully protect its intellectual property. A failure by the Company to
meaningfully protect its intellectual property could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
    As a general matter, the semiconductor industry is characterized by
substantial litigation regarding patent and other intellectual property rights.
The Company in the past has been, and in the future may be, notified that it may
be infringing the intellectual property rights of third parties. In November
1994, Cirrus Logic filed suit against the Company and certain of its employees
claiming, among other things, breach of fiduciary duty, breach of and
interference with contract and misappropriation of trade secrets. The Company
and Cirrus Logic settled the lawsuit in June 1996, but the Company incurred an
aggregate of $703,000 in expenses in connection with such litigation during
fiscal 1995 and fiscal 1996. This settlement did not involve cash payments, but
did include a non-solicitation provision and certain contingent cross-licensing
provisions. In February 1997, the Company received a written notice from Cirrus
Logic asserting that the Company's MagicGraph128, MagicGraph128V and
MagicGraph128ZV products infringe three United States patents held by Cirrus
Logic. The Company believes that the Company's MagicGraph128, MagicGraph128V and
MagicGraph 128ZV products do not infringe any of the claims of these patents.
The Company's belief is based upon a legal opinion from its patent counsel,
Townsend and Townsend and Crew LLP ("Townsend"). However, there can be no
assurance that Cirrus Logic will not file a lawsuit against the Company or that
the Company would prevail in any such litigation.
 
    Further, the Company was notified by certain of its customers that a law
suit had been filed and served by a holder of a United States patent asserting
that the video/graphics subsystem in such customers' notebook PCs, which use the
Company's MagicGraph128 and MagicGraph128V products, infringe certain claims of
the patent. The Company may have certain indemnification obligations to
customers with respect to the infringement of third-party intellectual property
rights by its products. There can be no assurance that the Company's potential
obligations to indemnify such customers will not have a material adverse effect
on the Company's business, financial condition and results of operations. The
Company believes that the Company's MagicGraph128 and MagicGraph128V products do
not infringe any of the claims of such patent. The Company's belief is based
upon a legal opinion from its patent counsel, Townsend and Townsend and Crew
LLP. There can be no assurances that the holder of such patent will not file a
lawsuit against the Company or its customers, that the Company or such customers
would prevail in any patent litigation, or that such customers will continue to
purchase the Company's products under the threat of litigation.
 
                                       6
<PAGE>
    Any patent litigation, whether or not determined in the Company's favor or
settled by the Company, would at a minimum be costly and could divert the
efforts and attention of the Company's management and technical personnel from
productive tasks, which could have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that current or future infringement claims by third parties or claims
for indemnification by other customers or end users of the Company's products
resulting from infringement claims will not be asserted in the future or that
such assertions, if proven to be true, will not materially adversely affect the
Company's business, financial condition and results of operations. In the event
of any adverse ruling in any such matter, the Company could be required to pay
substantial damages, which could include treble damages, cease the
manufacturing, use and sale of infringing products, discontinue the use of
certain processes or to obtain a license under the intellectual property rights
of the third party claiming infringement. There can be no assurance, however,
that a license would be available on reasonable terms or at all. Any limitations
on the Company's ability to market its products, or delays and costs associated
with redesigning its products or payments of license fees to third parties, or
any failure by the Company to develop or license a substitute technology on
commercially reasonable terms could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
BACKLOG
 
    Sales of the Company's products are primarily made pursuant to standard
purchase orders that are cancelable without significant penalties. In addition,
purchase orders are subject to price renegotiations and to changes in quantities
of products and delivery schedules in order to reflect changes in customers'
requirements and manufacturing availability. A large portion of the Company's
sales are made pursuant to short lead time orders. In addition, the Company's
actual shipments depend on the manufacturing capacity of the Company's suppliers
and the availability of products from such suppliers. As a result of the
foregoing factors, the Company does not believe that backlog is a meaningful
indicator of future sales.
 
EMPLOYEES
 
    As of January 31, 1998, the Company employed a total of 162 full-time
employees, including 91 in research and development, 10 in customer service and
applications engineering, 15 in sales and marketing, 19 in manufacturing and 27
in finance and administration. The Company also employs, from time to time, a
number of temporary and part-time employees as well as consultants on a contract
basis. The Company's employees are not represented by a collective bargaining
organization, and the Company believes that its relations with its employees are
good.
