Good afternoon. Thank you very much for coming to the Fiscal Year 2024 First Quarter Earnings Presentation for Yamaha Motor. I'll be serving as the MC today. I am from Corporate Communication Division. My name is Kurabe. Before going on into the presentation, I would like to introduce the presenter, our director, Motofumi Shitara. Today, Shitara will make the presentation, and after that, for the media and analysts, we will have a Q&A session on Zoom. The reference material could be accessed from Yamaha Motor's web page. So now we would like to move on into the presentation.
I am Shitara from Yamaha Motor. Thank you very much for attending the Yamaha Motor earnings presentation despite your very busy schedules. I would also like to take this opportunity to thank you all for your understanding and support to our operations on a daily basis.
Now I'd like to move on to my presentation of the outline of our earnings. Starting from first quarter of fiscal year 2024, our company has started applying international financial reporting standards, IFRS. From the next page onward, for last year and for this year as well, the material has all been made based on IFRS. First, the first quarter major points. Please refer to page 4. In the first quarter, the actuals, on a year-on-year basis, we have seen an increase in sales and profit. For motorcycles, in the emerging countries, premium model production and shipments have gone up, which led to an increase in sales and profit, and the operating income ratio has improved. In the marine business, in the developed countries, outboard motors shipment was down.
In robotics business, there was no change in the Chinese market and thus a reduction in sales and profit. Future outlook. Looking at the external factors, in many countries, monetary tightening is ongoing and the economic situation remains uncertain. Looking at each segment, including Yamaha, the supply situation has improved and tough competition is continuing. On the other hand, ocean freight and raw material costs have continued to go down. In our business, in the motorcycle business, in India, Brazil, Indonesia, these have been the drivers. Right now, the premium model supply for emerging countries are steady, and this has served as a tailwind. In marine business, outboard motors demand in emerging countries remains steady. In developed countries, the 300 horsepower plus large models are trending steadily. Activities to attain optimum level of inventory are showing effect.
We will continue to keep a close watch over demand and sales to continue to adjust our inventory. Looking at market trends, the changes are becoming apparent. We will continue to control expenses and improve production efficiency to strengthen our profitability. Also, in the premium strategy, including premium strategy, we will continue to focus on brand and product appeal to stand above price wars so that we can provide higher value through our products. Looking at the shipped units and inventory, please look at page 5. Let's look at, by major products, the sales units compared with the actuals for 2023. Strong demand continues in India and Brazil, and the premium model supply has stabilized in Indonesia. Especially in these countries, we have seen an increase in shipments.
Outboard motors, in developed countries, there were concerns of economic decline, which led to a decline in demand, and shipment also declined. ATV, ROV, demand is slowing down and competition is becoming intense. SPV, in the bicycle industry as a whole, inventory adjustments are continuing, and therefore, for these reasons, we are seeing a decrease. Surface mounters. In Europe, the shipment amount is decreasing. Looking at the right-hand graph, this is comparing the market stock with optimum level of stocks. Gray is last year as of the end of December. Blue is this year as of the end of March 2024. The finance regulation is becoming stricter, and Thailand, demand is lowering. But excluding that, inventory is above appropriate level with motorcycles in Vietnam and outboard motors in developed countries. And therefore, we are trying to reduce inventory towards an appropriate level.
Looking at business results overall, please refer to page 6. In the first quarter, revenue compared to previous year, 106%, JPY 642.1 billion. Operating income, 103% against the previous year, JPY 78 billion. Operating income ratio minus 0.4 points compared to the previous year, 12.1%. Net income attributable to owners of parent was 113% against the previous year, JPY 56 billion. EPS compared to the previous year, 116%, 56.6 JPY. Improved semiconductor supply situation in premium model sales in emerging countries have increased in motorcycles, and this was a driver for increased revenue. Also, for motorcycles, we were controlling expenses, and the positive effect of weaker yen led to an increase in profit. For the first quarter, we have a record high sales, operating income, and net income. The currency rate used was 149 JPY against the USD and 161 JPY against the EUR.
Next, for 2024 first quarter, some factors affecting operating income. Please refer to page 7. As you can see, sales effect had a negative impact of JPY 16.7 billion. However, if you look at the breakdown, financial services plus JPY 3.7 billion. Pricing, which includes pricing increase and rebates, was a plus JPY 2.4 billion. Unrealized profits, negative JPY 200 million. Scale effects, negative JPY 7.8 billion. And others, negative JPY 14.8 billion. The net cost impact was a positive JPY 2.4 billion. Breakdown is cost reduction, positive JPY 4.3 billion. Cost raises, negative JPY 1.6 billion. A growth strategy expense has increased, negative JPY 1.9 billion. SG&A increase, negative JPY 2.8 billion. Others, positive JPY 1.1 billion. Foreign exchange impact was a positive JPY 19.7 billion. Next, looking at the mid- to long-term measures and the progress. Please refer to page 8.
Our leadership in transparency in climate change area and performance has been recognized. In CDP 2023, we have received the highest score, A. For us, this is the first time to receive an A score. The CDP score is broadly utilized in decision-making for investments for a sustainable and flexible net-zero economy and also for purchasing decisions. Next, looking at the bottom, the British racing car development company, Lola. Together with them, we have concluded a technical partnership contract to develop and supply high-performance powertrain for Formula E. We will develop cutting-edge electric technology in order to raise the overall Yamaha's expertise in electrification. Next, we will go over details by business segment. I will start with the first quarter revenue operating income by business. Please refer to page 10. For land mobility, motorcycles, financial services, there was increased revenue and profit.
The ROV, SPV, and marine, robotics were lower revenue, lower OI, and other segments ended up with higher revenue, lower OI. Now, I'll go through the details in order. So please refer to page 11. Starting with our core business. On the left, we're showing motorcycles. The graph is showing revenue by region. With the developed countries, we saw a slight decrease. There was increased demand in India and Brazil. We had increased revenue in all regions. By improving the supply of premium models, our OI ratio also improved. For emerging countries, motorcycle premium strategy, we will be explaining the situation in our key markets later. Looking to the right for our marine products business, the graph is showing our revenue by product. For outboard models in emerging countries, we're continuing to see strong demand. In the West, 300+ HP large models are enjoying high demand.
The smaller models are in decline. This year, we announced the 350 HP new model. This has been very well received. However, overall, the demand decrease has had a major impact. So our first quarter ended with lower revenue, lower OI. We're also doing inventory adjustments by reducing production. So our OI ratio has worsened. And now we will look at our motorcycle business, looking at some topics on page 12. In the Indian market, we are pursuing a premium strategy. As part of our branding activities, we are reinforcing our customer engagement. This photo is from an overnight tour event. Compared to developed countries, in India, multi-day touring events are not well known. In 2023, we held the first such event. Since then, many users have been able to experience this wonderful event.
As another activity of reinforcing our brand, dealerships are hosting riding clubs, Blue Streaks, and offering circuit racing experiences. We're doing more than 1,000 events a year that have garnered 20,000+ participants. By providing new experiences to our customers, we want to promote the attractive qualities of motorcycles, not merely as a transportation device, to create core fans. Our motorcycle premium strategy in the emerging markets, here we will focus on key markets. So please refer to page 13. On the top row, we're looking at Indonesia and India, our actuals from 2019 to our forecast in 2024, looking at the transition of total demand. In 2020, we saw a huge decline due to the pandemic, but now the recovery is very steady. Bottom left is our premium strategy in Indonesia. In Indonesia, the NMAX and MAXi series is a part of our focus in the 155 cc class scooters.
From 2022, Fazzio, Grand Filano, and other Classy series products have been launched in the market as the second pillar after MAXI. These have been very well received. In the graph, we are showing the number of shipped units for these two categories. From 2021, there has been a shortage of semiconductors. Despite strong demand, we have not been able to keep up with our supply. This has been very frustrating, but now our supply has stabilized. On the right, for India, the 155 cc class sports-type segment is our focus. With the growing young population in India, we want to entice the Generation Z to have them grow their affinity for Yamaha brand. Stylish, sporty, and excitement, these are the perceptions now associated with Yamaha. On the graph, we're showing the sports category number of units shipped. You can see that we're showing a very steady increase.
From 2020 - 2024, our CAGR in total demand is +6%, but the premium category number of units shipped is +23% in Indonesia and +16% in India. So we continue to expect growth. In the emerging markets, we want the customers to understand the values that are unique to Yamaha. We will realize our premium strategy to enhance our revenue further. Next, we will look at our RV business and financial services. Please refer to page 14. On the left, we're showing our recreational vehicles. The overheated demand has normalized. Companies now have improved supply situations, and that has added inventory to the market. The price war is intensified. We have also had an increase in our SG&A cost and fewer units shipped. So that's lower revenue and lower profit.
On financial services, in North America and Brazil, we have increased our receivables due to higher units sold. The higher interest income and improved spreads has also led to increased revenue and profits. Lastly, we will look at our growth businesses of SPV and robotics. This is on page 15. On the left is our SPV business. There have been ongoing global market inventory adjustments that have made this a difficult market for us. Yamaha has continued to adjust its inventory, and we are looking to reduce inventory levels. We have fewer units sold, therefore lower revenue and lower profit. We believe that the trend will continue. Our inventory adjustments will continue. On the right, we have our robotics. For the surface mounters, there's no major change in the China situation. In Europe, there is concern over a likely recession and less capital expenditure.
We have received more inquiries for generative AI on semiconductor assembly devices. So this is in production full-time. Overall, for mounters and industrial robots, we had lower revenue and lower profit. Our OI ratio also worsened due to increased SG&A cost. Although we cannot afford to be optimistic, we have been getting more interest from China. We are getting ready for a recovery in demand by readying our production readiness. This concludes our explanation for quarter one of the fiscal term 2024. Thank you very much.
And with this, we would like to end our earnings presentation for the first quarter of fiscal year 2024. Thank you very much for watching the YouTube Live. And for the media, after this, we will have a Q&A session. So please wait a while. And please stay tuned.
