SUMCO CORPORATION

To Our Shareholders
Having taken offi ce as President of SUMCO Corporation on May 29, 2009, I take this
opportunity to extend my special thanks to you, our shareholders, for your continued
support and understanding. I would like to briefl y outline our position as we publish
our interim fi nancial statements for the fi scal year ending January 31, 2010.

The global economy took a sharp downturn in the fall of 2008, resulting in
drastically reduced demand for semiconductors and a serious deterioration in market
conditions for silicon wafers. As a result, the SUMCO Group has gone through the
most severe management environment it had ever experienced.

Since our public listing, SUMCO Corporation and our group companies have
endeavored to expand with a focus on silicon wafers for use in semiconductors.
However, faced with the challenges that emerged from the global economic downturn,
we announced our Business Restructuring Plan aimed at overcoming our diffi culties,
building a more resilient corporate structure, bringing our fi nances into the black as
soon as possible, and laying the foundation for sustained growth. The main points
of the Plan include “reorganization of small-diameter silicon wafer production,”
“strengthening the competitiveness of our solar wafer operations” in a world that is
increasingly conscious of the importance of global environmental preservation, and
“accelerating the depreciation of 300 mm wafer production facilities.”

Demand for silicon wafers for semiconductors bottomed out in the spring of
2009, and we are beginning to see some encouraging signs. However, we expect that
the SUMCO Group will continue to face severe business conditions for some time to
come. On the other hand, we expect our business domains to register strong medium-
to long-term growth. Looking beyond the diffi cult conditions that prevail today, we
shall do everything in our power to overcome our business challenges and to achieve
sound growth.

In light of the deterioration in our business performance, we have decided to
forego the payment of dividends for the interim period under review. Turning to the
future, the SUMCO Group will redouble its efforts to regain profi tability as soon as
possible. Meanwhile, we appeal to you, our shareholders, for your continued support
and cooperation.

First Three Months in Offi ce
Since taking offi ce three months ago, I have focused on our highest management
priority: the speedy implementation of our business restructuring program. The
goal of these initiatives is to realize stable growth in our businesses and to make
fundamental changes in our corporate and cost structures. The most critical
challenge is to achieve and maintain profi tability in the next fi scal year and beyond.

To achieve the speedy restructuring of our businesses in a rapidly
deteriorating business environment, the entire SUMCO Group needed to
appreciate the current situation, the goals, and feasibility of the proposed
reforms, and to arrive at a common management philosophy. For this purpose,
since taking offi ce, I have concentrated on visiting our plants and offi ces in Japan
and abroad. In the course of these visits, I have spent many hours discussing
the Business Restructuring Plan with our managers and frontline staff. This has
helped create a shared awareness of our management thinking and policies, and
a deeper understanding of the challenges before us and the measures we are
endeavoring to implement.
Objectives of the Business Restructuring Plan
Considering the sharp economic downturn starting in the fall of 2008, the
shift in demand structure, and the position in which the SUMCO Group finds
itself in this environment, there is an urgent need to implement the Business
Restructuring Plan.

A key element of the Plan is the reorganization of small-diameter silicon
wafer production. This strategy responds to the rapid shift to large-diameter

Implementing the Business Restructuring Plan a Robust Corporate Structure and to Achieve
Three months have passed since President Yoichi Taguchi took offi ce on May 29, 2009. During this period,
the SUMCO Group has grappled with the most difficult business environment that it has ever experienced.
President Taguchi speaks of the initiatives he has pursued while heading the Business Restructuring Plan and
touches on some directions for the future.

silicon wafers in global markets and is essential in improving our profi t structure.
This reorganization required the understanding of our customers, which
was obtained through extensive discussions. We are now implementing the
reorganization with full speed.

We are committed to improving our competitive position in solar wafers, an
area with strong growth potential. Responding to growing demand for crystalline
solar wafers, we have added monocrystalline products to our traditional lineup
of multicrystalline silicon wafers. We believe we can boost our competitiveness
by positioning ourselves to produce both types of products.

We are also accelerating the depreciation of 300 mm wafer production
facilities.

While we expect severe business conditions to prevail for some time to come,
we believe these measures must be speedily implemented to improve the future
profi tability of our businesses.
Achieving Sustained Growth
T
o overcome the current diffi culties, it is clear that we must fully implement the
Business Restructuring Plan. Not only will this improve our profi t structure but
it will also help create a more powerful human-resource base in the SUMCO
Group. We are confi dent that the achievement of these two goals will enhance
corporate competences that are essential to our success as a manufacturer, such
as manufacturing capabilities and development and technological capabilities.

We will enhance our customers’ trust and confi dence in us by paying close
attention to their needs and by supplying truly satisfying products supported by
the best available technologies.

We believe the combination of the corporate competences of the SUMCO
Group and our partnership with customers will serve as a foundation for creating
a company capable of achieving sustained growth and maintaining a robust
structure.

We eagerly look forward to the continued support of our shareholders.
