China Yuchai International Announces

Unaudited 2023 First Half-Year Financial Results

SINGAPORE, Singapore — August 10, 2023 - China Yuchai International Limited (NYSE: CYD) (“China Yuchai” or the “Company”), a leading manufacturer and distributor of engines for on- and off-road applications in China through its main operating subsidiary, Guangxi Yuchai Machinery Company Limited (“GYMCL”), wishes to announce today its unaudited consolidated financial results for the 2023 first half-year (“1H 2023”) ended June 30, 2023. The financial information presented herein for 1H 2023 and for the 2022 first half-year (“1H 2022”) are reported using the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board.

Financial Highlights for 1H 2023

Revenue was RMB 9.2 billion (US$ 1.3 billion) compared with RMB 8.6 billion in 1H 2022.

The total number of engines sold by GYMCL in 1H 2023 declined by 8.4% to 165,793 units compared with 180,911 units in 1H 2022. The decrease was mainly due to lower engine sales in the truck and agriculture application markets, partially offset by higher engine sales in the bus, industrial, and marine and power generation markets.

According to data reported by the China Association of Automobile Manufacturers (“CAAM”), in 1H 2023, commercial vehicle unit sales (excluding gasoline-powered and electric-powered vehicles) increased by 8.3% compared to 1H 2022 as truck and bus sales increased by 6.0% and 28.1% respectively.

Gross profit increased by 14.1% to RMB 1.6 billion (US$ 214.8 million), compared with RMB 1.4 billion in 1H 2022. Gross margin increased to 16.9% as compared with 15.9% in 1H 2022. The increase in gross profit and gross margin was mainly attributable to margin improvement across most market segments with greater sales of larger engines, and contributions from ongoing cost reduction efforts.

Other operating income increased by 59.3% to RMB 136.2 million (US$ 18.8 million) compared with RMB 85.5 million in 1H 2022. The increase was mainly due to higher government grants received and recognized.

Research and development (“R&D”) expenses decreased slightly to RMB 406.0 million (US$ 56.2 million) compared with RMB 408.5 million in 1H 2022. The Company continues to invest in research and development for on-road engines in the commercial vehicle markets and off-road engines as well as new energy products. Total R&D expenditures, including capitalized costs, were RMB 465.2 million (US$ 64.4 million) representing 5.1% of revenue in 1H 2023, as compared to RMB 476.9 million, or 5.6% of revenue, in 1H 2022.

Selling, general and administrative (“SG&A”) expenses increased by 19.3% to RMB 894.5 million (US$ 123.8 million) from RMB 749.6 million in 1H 2022. The increase was mainly due to higher provision for personnel and other selling and administrative expenses compared with the same period last year. SG&A expenses represented 9.8% of revenue for 1H 2023 compared with 8.7% in 1H 2022.

Operating profit rose by 34.6% to RMB 387.7 million (US$ 53.7 million) from RMB 288.0 million in 1H 2022. The operating margin was 4.2% compared with 3.4% in 1H 2022.

Finance costs declined by 2.9% to RMB 53.6 million (US$ 7.4 million) from RMB 55.2 million in 1H 2022.

The share of financial results of the associates and joint ventures was a profit of RMB 29.6 million (US$ 4.1 million) compared with a loss of RMB 30.9 million in 1H 2022. This improvement was primarily due to higher profits at MTU Yuchai Power Company Limited and a return to profitability at Y&C Engine Co. Ltd.

Income tax expense was RMB 110.6 million (US$ 15.3 million) as compared with RMB 56.5 million in 1H 2022. The change was mainly due to the higher taxable income in 1H 2023 and adjustment for under provision in the prior year.

Net profit attributable to equity holders of the Company was RMB 178.4 million (US$ 24.7 million) compared with RMB 93.7 million in 1H 2022.

Basic and diluted earnings per share were RMB 4.37 (US$ 0.60) compared with RMB 2.29 in 1H 2022.

Basic and diluted earnings per share for 1H 2023 and 1H 2022 were based on a weighted average of 40,858,290 shares.

Balance Sheet Highlights as at June 30, 2023

Mr. Weng Ming Hoh, President of China Yuchai, commented, “We achieved better financial results, with higher revenue, margins and earnings per share than the same period last year despite uneven growth in the China’s commercial vehicle markets. Investments in key joint ventures are now contributing more to net profits.”

“Our revenues in the first half of 2023 reflected the breadth of our product portfolio to serve our customers across a number of industries. We are confident that we can leverage the long-term growth potential of our businesses and create value for our shareholders,” Mr. Hoh concluded.
