Hello, everyone. I am Miyoshi, Head of Corporate Planning. Thank you very much for taking time out of your busy schedules to attend our financial results briefing today. Before I begin explaining the financial results, I would like to address two points. First, on July 14, we underwent an on-site inspection by the Japan Fair Trade Commission regarding transactions with a specific customer involving freezer and refrigerated equipment due to suspected violations of Antimonopoly Act. We take this matter very seriously and are fully cooperating with the investigation and taking appropriate measures. We deeply apologize for the considerable concern and inconvenience this has caused to our business partners and all other stakeholders. Second, I would like to address the Kumamoto earthquake that occurred on the 28th. We express our deepest condolences to those who lost their lives and extend our heartfelt sympathies to all those affected by the disaster.
With aftershocks continuing amid the intense heat, many people are living in a state of anxiety. We pray for the safety of everyone in the affected areas and for a swift recovery. We have many business partners in these regions. We will, of course, provide support to those partners and strive to offer as much assistance as possible. I would like to present the consolidated financial results for the first quarter of FY 2026. Net sales, operating profit, and profit attributable to owners of parent all recorded historical highs for the company, led by strong performance by the Energy and Industry segments. Please refer to the presentation material provided. I would like to start on page five, a summary of consolidated financial results in three months ended June 30, 2026, showing a year-on-year comparison. Net sales increased by JPY 25.3 billion year-on-year to JPY 273.3 billion, up 10% year-on-year.
Operating profit increased by JPY 6.9 billion -JPY 25 billion, up 38% year-on-year. Operating profit ratio at the end of the first quarter came to 9.2%. As for non-operating profit, as you can see on the right-hand side of the slide, net interest expenses, which includes a dividend increase and foreign exchange loss, were positive, having an impact. Ordinary profit increased by JPY 8.3 billion year-on-year -JPY 25.6 billion. As explained on the right-hand side of the slide, we recorded gain on sales of investment securities of JPY 7 billion in the first quarter, resulting in an extraordinary profit increase of JPY 7 billion year-on-year -JPY 6.8 billion. Profit attributable to owners of parent was up JPY 9.8 billion -JPY 20.7 billion. Please turn to page six for the waterfall chart showing the factors behind year-on-year changes in operating profit for the first quarter.
We saw an increase in sales and production volumes of JPY 8.9 billion year-on-year, which made a large contribution to record an operating profit of JPY 25 billion. I would like to highlight several points here. As for the JPY 8.9 billion increase in sales and production volumes, Automotive Semiconductor business in Semiconductors segment and Vending Machine business in Food and Beverage Distribution segment saw a decline in both sales and operating profit, but was offset by Power Generation business of Energy segment and Factory Automation Components business of the Industry segment, contributing to increased sales volumes. Fixed costs increased with a large increase of JPY 2 billion in labor costs. Other expenses increased by JPY 1.5 billion with increased sales volumes. Added value and others include impacts of rising raw material prices, which came to JPY 3.5 billion, differences in model mix and profitability between projects, and cost reduction, etc.
As explained before, rises in silver and copper prices are having an impact with ED&C Components business of the Industry segment and Semiconductors segment being affected the most. Additionally, we are seeing impact of rising raw material prices in parts of the Food and Beverage Distribution segment. On the other hand, regarding differences in profitability between models, improved profitability of plant and system projects involving Power Generation business and Power Supply & Facility Systems business contributed positively. Furthermore, in the Industry segment, Factory Automation Components business and ED&C Components business related to plant and system businesses also contributed to the results. The impact of foreign exchange rates was a positive JPY 900 million. Next page is an overview of net sales and operating profit by segment for the first quarter of FY 2026 and year-on-year changes.
As I mentioned at the beginning, the Energy and Industry segments are driving our performance. In previous earnings briefings, we have highlighted the solid performance of our plant and system-related businesses. The recent shift in component demand toward recovery has significantly contributed to the improvement in net sales and operating profit, particularly in the Industry segment. As of the first quarter, the operating profit ratio in the Energy segment rose to 14.7%. The Industry segment also improved significantly year-on-year to 8.2%. I will now explain the key points by segment. In the Energy segment, we achieved profit growth across all sub-segments. In particular, the Power Generation business contributed significantly to the year-on-increase in both sales and operating profit. Power Generation business accounted for approximately 70% of the segment's sales increase, up JPY 8.3 billion.
In addition to progress in construction projects and differences in profitability between projects, geothermal and hydro-electrical power projects overseas made a major contribution. In the Energy Management business as well, storage battery system orders and large-scale orders for substation equipment continue to perform solidly, resulting in increased sales and profits. Net sales in Power Supply & Facility Systems business, which are of great interest to everyone, decreased by 3% year-on-year. This was due to absence of large-scale data center related orders recorded during the same period of the last fiscal year. However, we were still able to secure an increase in profit. Furthermore, in the Equipment Construction business, both sales and profits remained steady. In the Industry segment as well, we achieved net sales growth across all sub-segments.
In addition to increased demand for ED&C Components business, the fact that the surge in raw material prices did not rise as sharply as initially anticipated also contributed to a significant improvement in operating profit. The main drivers of increased demand for ED&C Components were in semiconductor manufacturing equipment and AI-related applications, while demand from finished machinery manufacturers also expanded overall. In particular, Factory Automation Components and ED&C Components businesses are driving business performance, boosting both sales and operating profit. Furthermore, in the Factory Automation business, partly due to rebound from increased expenses for major projects recorded in the same period of the previous fiscal year, we achieved higher sales and a significant improvement in profits. Next, the Semiconductors segment. In the Automotive Semiconductor business, both sales and operating profit declined due to a decrease in demand from an overseas customer.
In the Industrial Semiconductor business, sales increased due to rising demand for motor drives. Operating profit for this segment declined due to the impact of soaring raw material prices and a decrease in demand in the Automotive Semiconductor business from an overseas customer in the electric vehicle sector. Next is our Food and Beverage Distribution segment. Sales and operating profits from Vending Machine business declined due to falling demand. Although we sought to offset this through Store Distribution business, we were unable to bring the overall operating profit back into positive. I will now explain net sales by Japan and overseas by areas. Of the total sales of JPY 273.3 billion, overseas sales amounted to JPY 82.4 billion, up JPY 11.6 billion year-on-year. Sales growth in Asia and India was the main driver of this increase in sales.
I will omit the details. Overseas as well, both the Energy and Industry segments are driving sales growth. I would like to explain orders received in the first quarter. Order for the same period last year was JPY 336.2 billion, for the current period, it increased JPY 91.1 billion year-on-year to JPY 427.4 billion. Breaking this down by Plant & Systems and Components and Others, Plant & Systems saw an increase of JPY 73 billion. Within Plant & Systems, the Energy segment saw an increase of JPY 90 billion compared to the same period last year. This growth was driven by Power Generation business and Power Supply & Facility Systems business. In particular, Power Supply & Facility Systems business accounted for approximately two thirds of this JPY 90 billion increase, showing a significant rise in orders.
I would like to comment on quarterly orders for major components. In line with the recovery in demand related to data center and semiconductors, orders for major components are also trending upward. I would like to draw your attention to several points. First, regarding ED&C Components business, orders increased 46% year-on-year and 40% quarter-on-quarter. Basically, demand from finished machinery manufacturers is on a recovery trend. Regarding the increase compared to the previous quarter, we analyzed that the impact of last-minute orders is evident in the comparison between the fourth quarter and the first quarter, following notification of price revisions to our customers. Demand for Factory Automation Components business also increased, primarily in the data center and semiconductor related businesses. Orders were down 9% compared to the previous quarter.
This is due to an absence of one-time large order received from a specific customer in the fourth quarter of last fiscal year. In the Industrial Semiconductor business, demand for motor drives increased both domestically and overseas. Since these motor drives are ultimately directed towards the semiconductor-related market and others, the Industrial Semiconductor business as a whole showed growth year-on-year as well as quarter-on-quarter. In Automotive Semiconductor business, results were negative due to factors such as declining demand from an overseas customer. I will now explain the consolidated balance sheet. Total assets for the first quarter decreased by JPY 48.9 billion from the end of the previous fiscal year to JPY 1,357.8 billion, due to factors such as a JPY 22.9 billion increase in inventories and a JPY 83.7 billion decrease in notes and accounts receivable compared to the end of the previous fiscal year.
The equity ratio was 58.2%. Net interest-bearing debt decreased by JPY 6.2 billion -JPY 13 billion, the net debt to equity ratio was 0.02 x to be precise. In addition, the JPY 21 billion share buyback, which we had previously announced, was completed during the first quarter and is reflected in these financial results. This is a statement of cash flows. Cash flows from operating activities improved by JPY 40.4 billion year-on-year to JPY 51.5 billion, primarily due to increase in cash provided due to decrease in accounts receivable trade and collections of advanced payments. Cash flows from investing activities improved by JPY 14.6 billion to a net outflow of JPY 7.2 billion, primarily due to higher proceeds from sale of investment securities and lower capital investment. As a result, free cash flow improved by JPY 54.9 billion year-on-year to JPY 44.4 billion.
Cash flows from financing activities reflect dividend payments of JPY 16.1 billion and share buyback totaling JPY 21 billion. This concludes the overview of our financial results. Based on our financial results for the first quarter and current business trends, we have revised our earnings forecast. We are revising upward our forecast for the six-month period ending September 30, 2026, from the forecast announced on April 28, with net sales up JPY 25 billion and operating profit up by JPY 14 billion. The reasons for this revision are to reflect the continued strong performance of the Energy segment, as well as the notable recovery in demand for components in the Industry segment and the expected increase in demand in the semiconductor industry business.
We are maintaining our exchange rate assumptions from the beginning of the fiscal year, regarding exchange rate sensitivity, we anticipate a negative impact of JPY 40 million from the US dollar and positive impact of JPY 60 million from the Chinese yuan. Compared to the same period of the previous year, we expect an improvement of JPY 50.8 billion in net sales, JPY 15.2 billion in operating profit, and JPY 13.4 billion in profit attributable to owners of parent. By segment, we also expect significant improvements in both the Energy and Industry segments. Next, I would like to discuss our full year consolidated earnings forecast. For the full year forecast, we have limited the adjustment to reflect only the upward revision for the first half, we have decided to maintain the initial plan for the second half.
As a result, our full year forecast is as follows: net sales of JPY 1.3 trillion, operating profit of JPY 156.5 billion, operating profit ratio of 12%, and profit attributable to owners of parent of JPY 111.5 billion, with rate of profit attributable to owners of parent to net sales of 8.6%. Amid a persistently complex external environment, regarding the outlook for the second half, we will closely monitor trends in plant-related orders and other factors, provide a further explanation at the time of the interim earnings announcements scheduled for the end of October. Finally, since this is a question we are asked every year, I would like to comment on foreign exchange. While we are maintaining exchange rate assumptions, the yen is currently trending lower.
In light of this, I would like to comment on how foreign exchange translation differences at our overseas subsidiaries will affect our financial results. Assuming current exchange rates are maintained, we expect first half results to show high single-digit billion yen increase in net sales, while operating profit will remain higher in the few hundreds of millions of yen range. For the full year, we currently estimate that this will result in an upside of approximately JPY 20 billion in net sales and several billion yen in operating profit. That was my final comment. Thank you for your attention.
