(A) Net income (loss) excludes amounts attributable to minority interests.
GigaMedia's subsidiary G-Music Limited ("G-Music") conducts an offline music
distribution business. Minority shareholders own a 41.4 percent equity interest
in G-Music.
(B) EBITDA (earnings before interest, taxes, depreciation and amortization) is
provided as a supplement to results provided in accordance with GAAP. See "Use
of Non-GAAP Measures" for more details.

Consolidated revenues for the third quarter of 2004 were $22.0 million, a 7
percent decrease over consolidated revenues of $23.7 million for the
corresponding period in 2003 and a decrease of 8 percent from consolidated
revenues of $24.0 million for the preceding quarter. The quarter-over-quarter
decline in consolidated revenues was largely due to the impact of the general
downturn in Taiwan's retail music distribution industry on the Company's music
distribution business.

Consolidated net income for the third quarter of 2004 was $688 thousand, a
turnaround of $3.4 million from a consolidated net loss of $2.7 million for the
same period in 2003 and an improvement of $129 thousand, or 23 percent, from
consolidated net income of $559 thousand for the preceding quarter. Driving the
increase in consolidated net income were strong expense controls in the
Company's broadband ISP operations and contributions from the Company's
entertainment software business, whose results began to be consolidated with
those of the Company starting April 1, 2004.

Consolidated EBITDA for the third quarter of 2004 was $2.8 million, compared to
consolidated EBITDA of negative $1.2 million for the same period in 2003. The
Company recorded consolidated EBITDA of $2.8 million during the preceding
quarter. The year-over-year increase in consolidated EBITDA reflected efficiency
improvements in all business units and strong contributions from the Company's
entertainment software business.

Cash and other cash equivalents at the end of the third quarter of 2004 totaled
$10.1 million, not including additional short-term investments totaling $34.9
million, compared to $9.9 million and $27.8 million, respectively, at the end of
the second quarter of 2004. During the third quarter, GigaMedia reclassified
previously made long-term bond fund investments totaling approximately $6.8
million as short-term investments, since the


maturation of these investments is now within one year.

The general market downturn in Taiwan's recorded music sales and delayed
releases by music labels of albums from certain top artists created a
challenging operating environment for the Company's music distribution business
in the third quarter. The music distribution business unit's net loss reflected
this decline in revenues. Efficiency gains achieved to date from ongoing
restructuring helped offset lower sales volumes during the period. Management
continues to take steps to lower fixed costs and increase efficiencies to
improve this business unit's performance. During the quarter, the Company closed
four underperforming stores and continued rollout of a point-of-sale system.

(A) In previous quarterly and annual releases, GigaMedia included corporate
headquarters expenses and certain other items in the Broadband ISP Unit results.
In the table above, all such amounts have been excluded for the current and past
periods. All numbers are presented on a consistent basis.

GigaMedia's broadband ISP business delivered increased profitability in the
third quarter. In order to retain subscribers in what remains a highly
competitive market, the Company's broadband ISP business is focused on providing
differentiated, value-added products and services to both consumers and
corporate customers. In line with this strategy, during the period, GigaMedia
launched the corporate broadband service ON-NET, providing connectivity services
between Taiwan, Hong Kong, and China. With the launch of the ON-NET service,
GigaMedia is well positioned to rollout additional value-added
telecommunications services targeting new corporate customers in Greater China.
Ongoing implementation of strict cost controls and enhanced efficiencies
resulted in net income of $869 thousand for the third quarter of 2004, compared
to a loss of $1.3 million for the same period in 2003.


The number of subscribers in the Company's consumer broadband ISP business
during the quarter ended September 30, 2004 decreased slightly compared to the
second quarter of 2004 to approximately 97,000, with blended average revenue per
subscriber ("ARPU") also down slightly compared to the second quarter of 2004 at
approximately $12.00 per month. The number of subscription lines in the
Company's corporate broadband ISP business increased by 14 percent
quarter-over-quarter, from 583 to 666 lines.

The Company's entertainment software business unit made positive contributions
to GigaMedia's financial results despite operating in what is seasonally the
slowest period for the business. Quarter-over-quarter declines in operating
income and net income were due to the slight decrease in revenue and to
investments in developing new game software and marketing during the period.
Overall market growth in online gaming remains strong; management is executing a
plan to expand the business and build a leading position in nascent,
non-English-speaking markets outside the United States and the United Kingdom.
During the third quarter, the entertainment software business completed
development of a multi-player, online poker product targeting
non-English-speaking markets and began to market the software to licensees.
Preliminary response has been encouraging. Development of additional non-English
language products and services is ongoing. The entertainment software business
also upgraded customer relationship management tools to enable more efficient
online marketing campaigns to licensees. Management expects continued
investments in new software games and upgrades of existing game products to
drive improved results going forward.


BUSINESS OUTLOOK

The following forward-looking statements reflect GigaMedia's expectations as of
December 2, 2004. Given potential changes in economic conditions and consumer
spending, the evolving nature of broadband and online entertainment software,
fluctuations in Taiwan's recorded music market and various other risk factors,
including those discussed in the Company's 2003 Annual Report or 20-F filing
with the U.S. Securities and Exchange Commission referenced below, actual
results may differ materially.


The general business environment remains challenging, with continuing weakness
in the music distribution market and strong competition in the broadband ISP
market. Despite these challenges, we remain highly confident in our ability to
deliver continued profitability and improved operating efficiencies.


USE OF NON-GAAP MEASURES

Management believes that EBITDA (earnings before interest, taxes, depreciation
and amortization) is a useful supplemental measure of performance because it
excludes certain non-cash items such as depreciation and amortization. EBITDA is
not a recognized earnings measure under GAAP and does not have a standardized
meaning. Non-GAAP measures such as EBITDA should be considered in addition to
results prepared in accordance with GAAP, but should not be considered a
substitute for, or superior to, other financial measures prepared in accordance
with GAAP. A reconciliation to the GAAP equivalent of the non-GAAP measure is
provided on the attached unaudited financial statements.


ABOUT THE NUMBERS IN THIS RELEASE

All figures referred to in the text, tables and attachments to this release are
unaudited. The financial statements from which the financial results reported in
this press release are derived have been prepared in accordance with U.S. GAAP,
and are presented in U.S. dollars.

Consolidated financial results of the Company for the third quarter of 2004 may
differ from totals of the Company's segmental financial results for the same
period due to (1) certain inter-company eliminations and (2) the impact of the
Company's corporate headquarters and certain non-operating subsidiaries of
GigaMedia on the Company's consolidated financial results.
