11. Qualitative Information Regarding the Consolidated Performance(1) Qualitative Information on the Consolidated Business Performance1) Overview of period under review
In the nine months ended December 31, 2012, the world economy overall slowed further due in part to the
influence of the European sovereign debt crisis in addition to a slowdown in the pace of economic expansion incountries such as China and India.
The economy of Japan showed signs of recovery driven by continuing reconstruction demand, but due tothe adverse effects of the slowdown in the global economy and some other factors, the process of normalizationof business conditions has come to a standstill.
The operating environment for the Mitsubishi Materials Group remained in the balance due in part to thesaturated “Eco-car subsidy” policy effect in addition to the drop in copper prices and stagnant demand insemiconductor-related markets despite the demand for reconstruction following the earthquake.
In this environment, we embarked on the medium-term management plan (FY2012-2014), entitled“Materials Premium 2013—For the Creation of New value”. The plan embraces the basic concept of“Simultaneously implementing growth strategies and financial improvements,” with two initiatives stated as
growth strategies: “Business advancement in overseas markets, especially newly emerging nations” and“Generation of distinctive synergies as an integrated business entity.” Based on this recognition, we havecontinued to implement various measures.
As a result, consolidated net sales for the period totaled ¥956,898 million, down 12.1% from the previous
corresponding period. Operating profit decreased 9.2%, to ¥39,684 million, and ordinary income increased
2.0%, to ¥55,100 million. Net income for the period increased 15.6%, to ¥30,591 million.

Increase/decrease (%)¥6.0(5.2%)¥3.7(50.2%)¥4.4(74.6%)In the domestic Cement business, the sales volume increased since in addition to the reconstruction demand due
to earthquake, there was also steady demand mainly for redevelopment construction and road related
construction in Tokyo metropolitan area. Overseas, demand decreased in China firstly due to a decrease ofinvestment in housing construction such as condominium buildings, and secondly due to the influence of delay
with resumption of high-speed rail construction and with progress with the new airport being constructed in
Shandong, however, the recovery trend in demand continued in United States mainly for private-sector capitalspending, and as a result, the sales volume increased. Total cement production for the period was 8.9 million
tons (equivalent to the same period of the previous year).
As a result, the entire Cement business posted year-on-year increases in both net sales and operating profit.
It also reported an increase in the ordinary income, due to an increase of operating profit from the previous
corresponding period.

Increase/decrease (%)¥(119.0)(-20.6%)¥(3.8)(-24.1%)¥0.1(0.5%)In the copper business, the Onahama Smelter & Refinery (operated by Onahama Smelting and Refining Co.,
Ltd., based in Fukushima Pref.), which suspended operations until the end of June 2011 due to the earthquake,
returned to normal operation. However, in addition to the production decrease in PT Smelting in Indonesia due
to furnace repairs and decrease in copper content in copper concentrates, factors such as a drop in copper prices
led to a decrease in net sales and operating profit. Total production of electrolytic copper for the period was 394
thousand tons, down 28 thousand tons from the previous corresponding period.
Gold and other valuable metals posted year-on-year decreases in net sales and operating profit due mainly
to decreased palladium price.
In the processed copper products business, sales of products for the automobile sector increased, however,2partly due to a drop of copper price and also to sluggish sales of products for construction sector, there was adecrease in both net sales and operating profit.
As a result, the entire Metals business reported year-on-year decreases in both net sales and operating
profit.
In addition, ordinary income increased from the previous corresponding period due to an increase individend income despite of a decrease in operating profit.

Increase/decrease (%)¥(7.5)(-6.8%)¥(3.1)(-27.5%)¥(3.0)(-28.8%)In cemented carbide products business, sales decreased due to the impact of the floods in Thailand anddeterioration in the market conditions. In addition, inventory valuation losses due to the declining raw material
prices were posted, and the cemented carbide products business ended with a decrease in net sales and operating
profit.
In the high-performance alloy products business, there was a decrease in net sales but an increase inoperating profit since although sales of motor products decreased as a result of a decrease in sales of
two-wheeled vehicles in Southeast Asia, demand in the aircraft-related market remained strong.
As a result, the entire Advanced Materials & Tools business posted a year-on-year decrease in both net
sales and operating profit.
It also reported a decline in ordinary income from the previous corresponding period due to a decrease inoperating profit.

The advanced materials business decreased in both net sales and operating profit despite healthy demand for
products for the smartphone sector and products for the automobile sector partly because of a decrease in thesales of products for solar battery sector.
In the electronic devices businesses, while demand in electronic devices-related markets suchas flat-screen TVs and personal computers stagnated, due to increase in sales for white goods, anoverall increase in revenues and profit was achieved.
Sales of polycrystalline silicon and related products decreased due to a downturn in themarket trend in semiconductor-related markets and solar battery-related markets, but due to theefforts made to increase the efficiency such as suspending operations of some production lines at
the Yokkaichi Plant, there was a decrease in net sales but an increase in operating profit. The
amount corresponding to fixed costs related to the production lines the operations that have beensuspended has been transferred to extraordinary losses.
As a result, the entire Electronic Materials & Components business reported year-on-year decreases in net
sales, but increases in operating profit.
Moreover, ordinary income for the entire business decreased on a year-over-year basis due in part to the
influence of a decrease in dividend income in spite of an increase in operating profit as well as recording theequity in earnings of affiliates.

In rolled aluminum and processed aluminum products, in addition to demand for products
for the automobile sector remained flat from the corresponding period of the previous year,
demand for products for can business increased, however, demand for the electronic materials
sector including products for the solar battery sector declined.
As a result, the entire Aluminum business posted a year-on-year decrease in net sales but an increase inoperating profit.
Ordinary income also increased thanks to the rise in operating profit from the previous corresponding
period.

increased the operating profits remained flat from the same period of the previous year.
E-waste (used electronics and electrical products) recycling business posted a decrease in both net sales
and operating profit due to the termination of the eco-point system for household appliances and the completionof the transition to digital terrestrial transmission.
In the precious metal business, there was a decrease in both net sales and operating profit since the trading
volume of gold bullion decreased due to the small change in gold prices, and also due to a decrease in thejewelry-related sales.
Orders for nuclear energy and engineering services amounted to ¥43.0 billion, up ¥5.4 billion from theprevious corresponding period. The order backlog at the end of the period was ¥22.9 billion, up ¥5.5 billion
from a year earlier.

(2) Qualitative Information on Consolidated Financial Position
Total assets as of the close of the consolidated 3rd quarter under review was ¥1,760.8 billion, an increase of ¥9billion from the previous consolidated accounting year closing. This is due to increases in merchandise andfinished goods.
Liabilities totaled ¥1,312.9 billion, a decline of ¥29.8 billion from the previous consolidated accounting year
closing. This is due primarily to a reduction in the long-term loans payable.

4(3) Qualitative Information on Consolidated Performance Forecasts
Regarding the business environment surrounding the Group, while reconstruction demand continues to arise, andthere is expectations for the economy to head toward recovery supported by the government’s economic policies,
etc. there is trend toward decline in sales of main products for automobile and electronic industry, etc. at thispoint.
Under these circumstances, the Company has revised the forecast for consolidated performance forecast for
the full-year period ending March, 2013, from as previously announced forecasts in November 7, 2012 as follows.
Due to the decrease in sales described above, the operating profit listed in the consolidated earnings forecast for
the financial year has been revised from the previous forecast of 62 billion yen to 54 billion yen. On the other
hand, net sales remain unchanged from the previous forecast due to the result of correction for a rising yen.
Ordinary profit remains unchanged from the previous forecast due mainly to an anticipated increase in dividends
income. Current net income has been revised from the previous forecast of 30 billion yen to 32 billion due to an
anticipated decrease in extraordinary losses as the result of reversal for loss on valuation of investment securities

Premium”) while focusing on both our growth strategy and enhancement of our financial position.

2. Summary Information (Notes)(1) Application of Specific Accounting Treatment
The Group rationally assumes an effective tax rate after applying tax-effect accounting to income before
income taxes for the consolidated fiscal year, including the period under review, and multiplies such effective
tax rate by quarterly income before income taxes to arrive at the tax expense.
(2) Changes in Accounting Policies; Changes in Accounting Estimates; Restatements(Change in Depreciation Method)
The Company and domestic consolidated subsidiaries changed to the depreciation method based on theamended Corporation Tax Act due to amendments to the Corporation Tax Act for tangible fixed assets acquired
on and after April 1, 2012 from the first quarter period. The influence of this change is minimal.
(Change in Depreciation Method and Estimate Useful Lives of Tangible Fixed Assets)
In the past, mainly the declining-balance method was applied in the depreciation method for
cement-related business facilities of the Company and its domestic consolidated subsidiaries, however,from the first quarter period, this has been changed to the straight-line method except for items inaccordance with the productive-output method. Taking advantage of the establishment of the new
medium-term management plan (FY2012-2014), the Company studied appropriate depreciation methods for
cement-related business facilities. As a result, an investment effect is expected on average since the stable useof facilities is expected from reasoning such as forecasts in the demand of cement and risk of technologicalobsolescence is small, therefore, the straight-line method was judged rational.

In addition, the Company and its domestic consolidated subsidiaries mainly applied the same standard
for estimated useful lives of machinery and equipment in the cement-related business as specified by the
Corporation Tax Act. However, taking advantage of the change in depreciation method, the estimateduseful lives for the following facilities were reassessed from the first quarter period. This reassessment wasdetermined based on a comprehensive consideration of physical useful lives as well as economic lifetime of
the corresponding facilities such as the useful lives of products and risks of production method5

obsolescence.

As a result of the above, compared with the values reached based on the conventional methods, operating
profit, ordinary income, and income before income taxes for the third consolidated quarterly cumulative
period have all increased by ¥ 1,287 million.

1. Change in Depreciation Method and Estimate Useful Lives of Tangible Fixed Assets
From the first quarter period, at the same time as the Company formulated the medium-term management
plan (FY2012-2014) for its Cement Business, the Company has revised the useful lives and changed
depreciation method for the equipment used by the Cement Business.
More details are shown on (2) Changes in Accounting Policies; Changes in Accounting Estimates;
Restatements (Change in Depreciation Method and Estimate Useful Lives of Tangible Fixed Assets) under “2.
Summary Information (Notes).”
As a result, as compared with the income calculated according to the former methods, the segment
income for the third consolidated quarterly cumulative period of the Cement Business increased by 1,287
million yen.
(5) Notes in Event of Significant Changes in Shareholders’ Equity: N/A(6)Important subsequent events
At the Board of Directors Meeting held on December 21st, 2012, our company decided to make ourconsolidated subsidiary Robertson’s Ready Mix, Ltd., for which our consolidated subsidiary MCC
Development Corporation owns 70% of the equity interest, and 3 other companies (hereinafter referred toas “Robertson’s, etc.”), the wholly-owned subsidiaries of MCC Development Corporation. MCC
Development Corporation acquired all equity in Robertson’s, etc. and acquired the companies aswholly-owned subsidiaries on December 31st, 2012, after the settlement date (September 30th, 2012) for the
3rd quarter of MCC Development Corporation.
U.S. Accounting Standards are followed for MCC Development Corporation and changes in
non-controlling interest after acquiring control are accounted for as capital transactions. Therefore, we
forecast that our company’s total shareholders’ equity will decrease by approximately 30 billion yen during
settlement for the year ending March 31, 2013.
The forecasted amount may change in the future because the year-end settlement (December 31st, 2012)
for MCC Development Corporation has not been finalized.
