It is now this scheduled time. We will begin the Mitsubishi Electric Financial Briefing for Fiscal 2025. I would like to introduce today's presenters: Mr. Kei Uruma, Representative Executive Officer, President, CEO; Mr. Kenichiro Fujimoto, Executive Officer, CFO. Now, President Uruma, please proceed.
Hello, everyone. I was just introduced. I am Uruma of Mitsubishi Electric, and I'd like to thank you for attending our Consolidated Financial Results Briefing today. I will first highlight the key points of the financial results, followed by our CFO, Fujimoto, who will cover the details. I would like you to refer to page 3 now. I'd like to explain the key points of the financial results, starting with the results for fiscal year 2025. The Group's revenue increased JPY 263.7 billion—that's a 10.5% increase from the previous fiscal year—to JPY 5,521.7 billion, and operating profit increased JPY 63.3 billion to JPY 391.8 billion—that's a 119% increase.
The Factory Automation Systems business was affected by the delayed market recovery, but due to increased sales and profitability in the Infrastructure and Life segments, as well as improved profitability, and also the improved profitability in the Semiconductor & Device segment, we achieved record-high revenue, as well as operating income, and also met our initial corporate target for net profit. In the FA Systems business, the scale of Factory Automation Systems declined; the revenue declined, along with profitability. However, through drastic measures in low-profit businesses and fixed-cost reductions, etc., we will be done exhaustively this year, and we hope to strengthen our business in China.
We hope to quickly return to a growth trajectory. We hope to return the business in China to a growth orbit as soon as possible. As for free cash flow, it totaled JPY 640 billion—sorry, JPY 264.1 billion increase. In fiscal year 2025, we enhanced business competitiveness through M&A to expand the air conditioning business in Europe and a decision to establish a China business regional headquarters for FA systems. In addition, regarding the China business regional headquarters, up to now, production and distribution were the only outlets in China, but we want to add a development function so that we can locally produce for the local market in China.
That is why we decided to establish this China regional headquarters company. As for—you know about the transfer of shares in our group logistics Company, and we will also sell off our cross-held shares in order to improve asset efficiency. Also, last week, we announced about the vehicle lamp system business. We announced the establishment of a JV, joint venture, and we are also promoting portfolio reforms in the Automotive Equipment business. In 2026, we will further accelerate such moves. Also, in our 2026 full-year performance outlook, we forecast a revenue of JPY 5,400 billion and operating profit of JPY 430 billion, which will be an all-time high for the operating profit. Meanwhile, the impact of U.S. tariffs and the details will be, of course, given by our CFO, Fujimoto.
However, we have factored into the earnings forecast an impact of close to JPY 30 billion, but currently, in areas where calculations are possible, we have calculated the impact. Because there is a lot of fluctuation, we would like to revisit our earnings forecast as well as the impacts. We would like to cope with the U.S. tariff increases through price hikes. We have also decided today to repurchase our own shares, and we'll continue to invest in growth, promote its business portfolio strategy, and strengthen our management structure while steadily returning profits to shareholders with the aim of achieving an ROE of 10% as soon as possible. Now then, I would like to call upon Fujimoto Kenichiro, our CFO, to explain the details of the financial results.
This is Fujimoto. I will now explain the details of the financial settlement in accordance with the handout material. Please refer to page 5. The Group's revenue increased JPY 263.7 billion year-on-year to JPY 5,521.7 billion. That's 105% of the previous year. Revenue increased over the previous year, even after excluding the exchange rate impact of JPY 109 billion. Operating income increased JPY 63.3 billion to JPY 391.8 billion, 119% of the previous year's level. Even excluding the foreign exchange impact of JPY 30 billion, operating income increased year-on-year. The operating profit margin was 7.1%, an improvement of 0.9 percentage points from the previous year.
In addition to the record revenue and operating income Uruma mentioned earlier, profit before income taxes and net profit attributable to shareholders of Melco also reached record highs. Now, please turn to page 6. This waterfall chart shows year-on-year changes in revenue and operating profit. The foreign exchange impact increased net revenue by JPY 109 billion and profit by JPY 30 billion. Aside from Forex, we were impacted by a JPY 37 billion cost increase in materials and distribution expenses and negative changes to the product mix, such as the decreasing ratio of the highly profitable FA systems business, as well as a one-time charge of JPY 15 billion.
However, price improvement of JPY 48 billion improved profitability, mainly in the Infrastructure and Life divisions, and the sale of non-core businesses resulted in increased revenue and operating profit for the year. Now then, please turn to page 7. I will highlight some items in the Consolidated Statement of Profit and Loss that have not been mentioned so far. The cost of sales ratio improved 1.2 percentage points from 70.6% in the previous fiscal year to 69.4%, as the impact of price improvements and more selective order taking began to take effect in all businesses.
Selling, general, and administrative expenses increased by JPY 78.5 billion from the previous year, mainly due to an increase in personnel development and marketing expenses. The foreign exchange impact was JPY 20.3 billion. Now, please turn to page 8. I will explain the Consolidated Statement of Financial Position. Assets increased by JPY 208.3 billion from the end of the previous fiscal year, mainly due to an increase in trade receivables and contract assets resulting from sales growth, mainly in the made-to-order business. \
Equity attributable to Melco shareholders decreased by JPY 104.3 billion due to dividend payout, but we recorded JPY 324 billion in net profit attributable to Melco shareholders, which increased our equity by JPY 210.3 billion from the end of the previous fiscal year to a total of JPY 3,949.6 billion. The ratio of equity attributable to Melco shareholders to total assets rose 1.3 percentage points from the end of the previous fiscal year to 61.9%. Operating cash flow was an inflow of JPY 455.9 billion, an increase of JPY 40.4 billion from the previous year, mainly due to an increase in net income.
Cash outflow from investing activities increased by JPY 97.6 billion over the previous year due to a decline in sales proceeds on securities, resulting in an investment cash outflow of JPY 191.7 billion. As a result, free cash flow decreased by JPY 57.2 billion from the previous year to a total inflow of JPY 264.1 billion. Now, turning on to page 10, I will now briefly explain each of our business segments. The following waterfall chart illustrates the fiscal year 2025 revenue and operating profit by segment compared to the previous year. Infrastructure, Life, and Business Platform segments increased both revenues and profits. Semiconductor devices increased profits despite lower revenues, while the Industry & Mobility Segment reported lower revenues and profits.
Please refer to page 11. This is the infrastructure segment. Both the segment and all subsegments achieved year-on-year growth. The Public Utility System business grew steadily with strong UPS demand for overseas data centers and solid transportation and public sector projects, leading to higher orders, revenue, and profit. Energy Systems also saw strong demand supported power demand increase along with data center expansion. Despite one-time cost increase in Power Distribution business and improved order margins lifted both revenue and profit year-on-year basis.
Orders for Defense and Space Systems rose sharply due to defense capability preparation plans and driving gains in year-on-year basis revenue and operating profit. Improved contract terms in defense, increased orders, and stabilization of high-difficulty space projects boosted operating margins significantly. Steady growth in both revenue and profit is expected to continue. Please refer to page 12. Industry and Mobility segment. The Factory Automation System business faced continued challenges due to delay of investment in the lithium-ion battery sector.
Orders are recovering by capturing market demands in smartphones, AI, and machine tools, but demand for high-margin models has yet to rebound. Sales mix changes and one-time costs led to lower year-on-year revenue and profit. We are now accelerating efforts to meet our financial targets by optimizing fixed costs and strengthening business in China. Automotive Equipment sales fell due to lower China demand, but operating profit rose year-on-year thanks to pricing and cost improvements. Please refer to page 13, Life segment. In the Building System business, growth in renovation projects in Japan and Asia, excluding China, led to year-on-year higher orders, revenue, and profit.
In Air Conditioning and Home Appliances business, European demand was sluggish, but North America, Asia, and Japan remained strong. Despite one-time costs, price improvements drove gains in both revenue and profit. Please move over to page 14. The Business Platform segment maintained steady demand, achieving higher orders, revenue, and profit on a year-on-year basis. In Semiconductor and Device segment, power semiconductor demand stagnated in industry and automotive domains, but telecommunications optical device demand remained firm, while year-on-year revenue stayed flat, but operating profit increased due to a better sales mix.
Please refer to page 15. Now, sales by customer location. In the year ending March 2025, overseas sales grew 4%, led by air conditioning and power systems, and domestic sales grew 6%, driven by Defense and Space Systems. The overseas sales ratio remained steady at 51%. Please refer to page 17. Now, this is the outlook for the year ending March 2026. The forecast revenue of JPY 5.4 trillion, operating profit of JPY 430 billion, and 8% operating margin. Although stronger yen will lower our revenue, we expect record high operating profit, pre-tax profit, and net profit attributable to the owners of the parent company. As for the estimated rate for the exchange rate, it is JPY 140 to a dollar, JPY 155 to a euro, and JPY 19.5 to a yuan.
As for U.S. tariff impact, which is shown on the right bottom table, what company sells to the United States is about JPY 600 billion, of which 80% is sourced outside of the United States, making them subject to tariffs. We have forecasted in the full year impact of JPY 30 billion from the 10% baseline tariff and additional tariffs on steel and aluminum based on the current policy. We are aiming to transfer full impact to our costs, but have included the estimation of JPY 30 billion as a loss, considering uncertainty risks of service declines and additional tax measures.
We will closely monitor tariffs and speed up relevant local productions. Please refer to page 18. Next, this is the changes in the year ending March 2026 forecast versus the previous year. The strong yen will reduce revenue by JPY 190 billion and operating profit by JPY 47 billion. Excluding exchange rate effect, we forecast a JPY 68.3 billion revenue increase and JPY 85.2 billion profit increase. We expect Infrastructure and Life segment to expand from last fiscal year.
We forecast JPY 430 billion operating profit with business service expansion and profitability improvement, cost structure review for the business structure, and elimination of one-time cost. We forecast JPY 430 billion operating profit. While Industry and Mobility segments revenue will decline over the previous fiscal year, business growth, profitability improvements, and cost reduction in Infrastructure and Life segment would improve the profitability. Our entire group expects to increase profit while decreasing revenue. This concludes our presentation.
