China Yuchai International Announces Unaudited

2023 Second Half-Year and Full Year Financial Results

SINGAPORE, Singapore — February 27, 2024 - China Yuchai International Limited (NYSE: CYD) (“China Yuchai” or the “Company”), one of the largest powertrain solution manufacturers through its main operating subsidiary in China, Guangxi Yuchai Machinery Company Limited (“GYMCL”), wishes to announce today its unaudited consolidated financial results for the 2023 second half year (“2H 2023”) and fiscal year ended December 31, 2023 (“FY 2023”). The financial information presented herein for the second half year and fiscal year of 2023 and the second half year (“2H 2022”) and fiscal year ended December 31, 2022 (“FY 2022”) are reported using the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board.

Financial Highlights for 2H 2023

Revenue was RMB 8.9 billion (US$ 1.3 billion) compared with RMB 7.5 billion in 2H 2022.

The total number of engines sold in 2H 2023 increased by 5.2% to 147,700 units compared with 140,345 units in 2H 2022. The increase was mainly due to higher heavy-and medium-duty engine sales in the truck and bus markets as well as increased sales in the marine and power generation and industrial markets.

According to data reported by the China Association of Automobile Manufacturers (“CAAM”), in 2H 2023, commercial vehicle unit sales in China (excluding sales of gasoline-powered and electric-powered vehicles) increased by 28.2% compared to 2H 2022, as sales of trucks and buses increased by 28.0% and 29.5% respectively.

Gross profit was RMB 1.4 billion (US$ 202.4 million), compared with RMB 1.2 billion in 2H 2022. Gross margin was 16.2% in 2H 2023 compared with 16.1% in 2H 2022.

Other operating income increased by 21.8% to RMB 306.2 million (US$ 43.2 million) compared with RMB 251.3 million in 2H 2022. The increase was mainly due to a gain of RMB 113.0 million on the disposal of a subsidiary. Excluding this one-off item, the other operating income would have been RMB 193.2 million (US$ 27.3 million), lower by RMB 58.1 million compared with 2H 2022. This decline was mainly attributable to lower government grants.

Research and development (“R&D”) expenses increased by 9.9% to RMB 470.5 million (US$ 66.4 million) compared with RMB 428.0 million in 2H 2022 due to higher personnel salaries and related expenses. Total R&D expenditures, including capitalized costs, were RMB 599.2 million (US$ 84.6 million) representing 6.8% of revenue in 2H 2023, as compared to RMB 540.8 million representing 7.2% of revenue in 2H 2022.

Selling, general and administrative (“SG&A”) expenses increased by 31.7% to RMB 1.0 billion (US$ 147.9 million) from RMB 795.3 million in 2H 2022. The increase was mainly due to increased personnel salaries and related expenses, and higher warranty and travel expenses compared with the same period last year. SG&A expenses represented 11.8% of revenue for 2H 2023 compared with 10.7% for 2H 2022.

Operating profit was RMB 221.8 million (US$ 31.3 million) from RMB 231.3 million in 2H 2022. The operating margin was 2.5% compared with 3.1% in 2H 2022.

Finance costs increased by 15.6% to RMB 46.5 million (US$ 6.6 million) from RMB 40.2 million in 2H 2022 primarily due to higher bills discounting.

The share of financial results of the associates and joint ventures climbed to a profit of RMB 32.5 million (US$ 4.6 million), compared with RMB 1.8 million in 2H 2022. The improvement was mainly driven by higher profits at MTU Yuchai Power Company Limited, and significantly reduced losses at Y&C Engine Co., Ltd. and Guangxi Purem Yuchai Automotive Technology Co., Ltd.

Income tax expense was RMB 37.9 million (US$ 5.3 million) compared with RMB 2.6 million in 2H 2022. The change was mainly due to under-provision in prior years and higher taxable income in the same period of 2023.

Net profit attributable to equity holders of the Company was RMB 107.1 million (US$ 15.1 million) compared with RMB 124.9 million in 2H 2022.

Basic and diluted earnings per share were RMB 2.62 (US$ 0.37) compared with RMB 3.06 in 2H 2022.

Basic and diluted earnings per share for 2H 2023 and 2H 2022 were based on a weighted average of 40,858,290 shares.

Financial Highlights for FY 2023

Revenue was RMB 18.0 billion (US$ 2.5 billion) compared with RMB 16.0 billion in FY 2022.

The total number of engines sold in FY 2023 decreased by 2.4% to 313,493 units compared with 321,256 units in FY 2022. The decrease was mainly due to lower sales in the truck and agricultural markets, partially offset by increased sales in the bus, industrial, marine and power generation and new energy markets.

According to CAAM, commercial vehicle unit sales in China (excluding sales of gasoline-powered and electric-powered vehicles) increased by 17.2% year-over-year in FY 2023, as sales of trucks increased by 15.6% and the smaller bus market sales increased by 28.8%.

Gross profit increased by 16.7% to RMB 2.9 billion (US$ 411.7 million) compared with RMB 2.5 billion in FY 2022. Gross margin increased to 16.2% compared with 15.6% in FY 2022. The increase in gross margin was mainly attributable to higher revenue from heavy-duty engines and continuing cost reduction initiatives, partially offset by higher customer sales rebates.

Other operating income increased by 31.4% to RMB 442.4 million (US$ 62.5 million) compared with RMB 336.8 million in FY 2022. The increase was mainly due to a gain of RMB 113.0 million on disposal of a subsidiary. Excluding this one-off item, the other operating income would have been RMB 329.4 million (US$ 46.5 million) in FY 2023.

R&D expenses increased by 4.8% to RMB 876.6 million (US$ 123.8 million) compared with RMB 836.4 million in FY 2022.

In FY 2023, total R&D expenditures including capitalized costs were RMB 1.1 billion (US$ 150.3 million) compared with RMB 1.0 billion in FY 2022, representing 5.9% of the revenue compared with 6.4% in FY 2022.

SG&A expenses were RMB 1.9 billion (US$ 264.3 million) representing 10.4% of the revenue, compared with RMB 1.5 billion, representing 9.2% of the revenue in FY 2022. This increase was mainly due to higher personnel and related expenses and warranty expenses compared with last year.

Operating profit grew by 17.4% to RMB 609.4 million (US$ 86.0 million), compared with RMB 519.3 million in FY 2022. The operating margin was 3.4% compared with 3.2% in FY 2022.

Finance costs increased by 4.9% to RMB 100.2 million (US$ 14.1 million) from RMB 95.5 million in FY 2022.

The share of financial results of the associates and joint ventures was income of RMB 62.1 million (US$ 8.8 million) compared with a loss of RMB 29.1 million in FY 2022. The income was primarily generated by higher profits at MTU Yuchai Power Company Limited, and the share of lower losses at Y&C Engine Co., Ltd. and Guangxi Purem Yuchai Automotive Technology Co., Ltd.

Income tax expense was RMB 148.5 million (US$ 21.0 million) as compared with RMB 59.1 million in FY 2022. The increase was mainly due to under-provision in prior years and higher taxable income in FY 2023.

Balance Sheet Highlights as at December 31, 2023

Mr. Weng Ming Hoh, President of China Yuchai, commented, “Our strategy of maintaining a diverse product portfolio serving multiple end markets proved effective in generating profitable revenue growth amid uncertain times. In 2023, the Chinese economy grew by approximately 5.2%, an increase from the 3% growth in 2022 during the post COVID-19 recovery period. Despite the overall economic growth, the Chinese property market remained weak, experiencing a decline in new construction throughout 2023. Non-government fixed asset investment (excluding rural households) declined by 0.4% for the year. Consumer confidence remained subdued resulting in deflationary pressures and heightened uncertainty for future growth.”

“Despite these challenges, we are pleased to report that our heavy-duty engines for the truck and bus markets experienced robust growth in the second half of 2023. In addition, our marine and generator business achieved over 20% growth. Key joint ventures demonstrated enhanced operational performance throughout 2023.”

“Our strong balance sheet provides the resources to take advantage of future growth opportunities,” Mr. Hoh concluded.
