(TRANSLATION)

THE 59TH BUSINESS REPORT

For the Annual Period Ended March 31, 2005

This is a translation of the original Business Report written in the Japanese
language, prepared primarily for the benefit and information
of shareholders of the Company’s common stock.

PIONEER CORPORATION
Tokyo, Japan

TO OUR SHAREHOLDERS

During the 59th annual accounting period, ended March 31, 2005, consolidated operating revenue of Pioneer Corporation was ¥733,648 million, up 4.7% over the previous year.

The Company posted net loss of ¥8,789 million, compared with net income of ¥24,838 million recorded in the previous year, due mainly to decreased gross profit margin resulting from intensified price competition for our major products. In addition, impairment losses of carrying value of certain production facilities and losses in connection with withdrawal from the North American cable TV set-top box business were recognized.

Year-end dividend payments were set at ¥12.5 per share of common stock, the same amount as in the previous year. Adding this to the interim dividend paid last December brings the total annual cash dividend to ¥25, the same amount as in the previous year.

The business environment remains severe, characterized by uncertain economic conditions in our major markets — Japan, North America and Europe — lower prices and harsher competition beyond our projections in our major product categories, and exchange rate fluctuations. To cope with the situation and recover profitability quickly, we are advancing cost reduction efforts among the group companies. At the same time, we are focusing our resources in our strategic businesses.

We are reviewing our production system and the reduction of product models to reduce costs on a global scale. In addition, we are reducing inventory in the whole process from parts procurement to marketing through our supply chain management. We will also adjust staffing to more appropriate levels throughout the group companies.

In our plasma display business, competition is getting severer while demand is steadily expanding. To cope, we are integrating our

technologies with those of our new manufacturing subsidiary, which joined the Pioneer Group in October 2004, and raising the yield rate and reducing the number of parts. To enhance our products’ competitiveness, we are also reducing product power consumption levels and developing high-quality full-specification high-definition plasma TVs.

In the DVD business, markets for DVD recorders, especially those with hard disk drives (HDDs), and recordable DVD drives for personal computers (PCs) are rapidly growing. On the other hand, prices are getting lower and competition is getting harsher. Therefore, we are speeding up new product development cycles so that our products are more in sync with market trends. We are continuing full-fledged efforts to cut costs and reduce inventory by integrating production from laser pickups to finished products in China. We are also expanding sales of drive units for DVD recorders to other manufacturers on an OEM (original equipment manufacturing) basis.

Our car electronics business aims to widen its lead in the consumer and OEM markets. Our car navigation systems enjoy an excellent reputation in Japan, and we also intend to expand this business in Europe and North America, where our sales of these systems have been steadily growing. In the car audio business, we plan to fortify our strong position with distinctive new products, and maintain our sales drive in such growing markets as China and Central and South America.

We appreciate the support that shareholders have always given us, and look forward to more of it. And we will keep doing everything in our power to improve shareholder value.

CONSOLIDATED OPERATING REVENUE BY BUSINESS SEGMENT

Percent of Operating Revenue

Year ended March 31

(PERCENT OF OPERATING REVENUE)

Home Electronics

This segment includes DVD players, DVD recorders, recordable DVD drives, DVD-ROM drives, home-use plasma displays, stereo systems, individual stereo components, equipment for cable TV systems and telephones.

Sales in the Home Electronics segment increased 7.0% to ¥301,228 million from the previous year.

In Japan, sales rose 11.6% to ¥87,954 million, primarily due to a large increase in sales of plasma displays, including the expansion of our OEM product sales, despite decreased sales of recordable DVD drives for PCs, DVD recorders and audio products.

Overseas sales also rose 5.2% to ¥213,274 million, due to an increase in sales worldwide of plasma displays and DVD recorders, despite a decrease in sales of audio products and DVD players worldwide and recordable DVD drives in Europe and North America, as well as the withdrawal from our cable TV set-top box business in North America.

Car Electronics

This segment includes car stereos, car AV (audio/video) systems, car speakers and car navigation systems.

Sales in the Car Electronics segment increased to ¥303,410 million, up 3.8% from the previous year.

In Japan, sales decreased 1.2% to ¥120,260 million, influenced by decreased sales of car navigation systems in the consumer market. This offset an increase in sales of car navigation systems in the OEM market, reflecting shifting demand from the consumer market to the OEM market.

Overseas sales increased 7.4% to ¥183,150 million, due to increased sales of car audio products for the OEM market and car navigation systems in Europe and North America, and of car audio products for the consumer market in Central and South America, despite decreased sales of car audio products for the consumer market in Europe and North America.

Patent Licensing

This segment includes the licensing of patents related to laser optical disc technologies.

Royalty revenue from Patent Licensing decreased 13.4% from the previous year to ¥10,237 million, reflecting the expiration of patents included in a larger portfolio of patents licensed to the optical disc industry.

Others

This segment includes business-use plasma displays, business-use AV systems, organic light-emitting diode (OLED) display panels, factory automation (FA) systems, and devices and parts.

Sales in this segment increased 2.9% from the previous year to ¥118,773 million.

In Japan, sales decreased by 14.1% to ¥53,935 million, primarily due to a decrease in sales of OLED display panels and a sales shift from Japan to China of semiconductors for laser pickups, despite an increase in sales of FA systems.

Overseas, sales were up 23.3% to ¥64,838 million, primarily due to increased sales in China of devices for cellular phones and semiconductors for laser pickups, and in Asia of speaker devices for cellular phones, despite decreased sales in North America and Europe of plasma displays for business use.
