FirstHalf 2026 Financial Results

Revenues

Our revenues for the six months ended December 31, 2025 and 2024 were $19.2 million and $17.0 million, respectively. The 13.41 % increase in revenues was mainly driven by the increase in order volumes and increase in sale prices of specialized oilfield vehicles. This increase was partially offset by the decrease in demand for sales of specialized oilfield equipment.

Costof revenues

Cost of revenues consists primarily of manufacturing and purchase cost of raw materials, depreciation, maintenance, and other overhead expenses. Our cost of revenues increased by $2.2 million, or 18.99%, to $14.0 million for the six months ended December 31, 2025 from $11.8 million for the six months ended December 31, 2024. The increase in cost was mainly attributable to increase in sales volume for specialized oilfield vehicles.

Grossprofit

Gross profit remained steady at $5.2 million for the six months ended December 31, 2025 and 2024. Gross profit margin decreased from 30.65% for the six months ended December 31, 2024 to 27.24% for the six months ended December 31, 2025. The decrease in gross profit margin was primarily driven by increase in production cost of newly developed vehicles and our promotional sales policy to expand the market. The gross profit remained steady mainly due to the decrease in unit profit margin was offset by an increase in sales volume.

Sellingand marketing expenses

Our selling and marketing expenses consist primarily of commission.

Our selling and marketing expenses slightly decreased by $0.1 million, or 13.76% , to $0.5 million for the six months ended December 31, 2025 from $0.6 million for the six months ended December 31, 2024. The observed revenue expansion reflects our management team’s direct business development efforts rather than commission-based sales channels, thereby maintaining stable commission expenditure.

Generaland administrative expenses

Our general and administrative expenses consist primarily of professional fees, salaries and welfare expenses, provision for credit losses, and others, which primarily includes depreciation and amortization expenses and rental expenses.

Our general and administrative expenses increased by $0.2 million, or 27.27%, to $1.0 million for the six months ended December 31, 2025 from $0.8 million for the six months ended December 31, 2024, which attributed to the increase in professional fees of $0.7 million and was offset by an decrease of provision for credit losses $0.5 million.

Researchand development expenses

Our research and development expenses consist primarily of (i) parts and materials in relation to testing materials; and (ii) design and development expenses, with new technology, materials and suppliers and other research and development related expenses for designing and testing.

Research and development expenses slightly increased by $0.1 million, or 2.69%, to $1.6 million for the six months ended December 31, 2025 from $1.5 million for the six months ended December 31, 2024. The increase in research and development expenses is mainly driven by the stage and scale of our equipment development.

Incometax expense

The People’s Republic of China enterprise income tax (the “EIT”) is calculated based on the taxable income determined under the applicable EIT Law and its implementation rules. Our income tax expense remained steady at $0.2 million for the six months ended December 31, 2025 and 2024.

Netincome

As a result of the foregoing, we recorded net income of $1.8 million and $2.0 million for the six months ended December 31, 2025 and 2024, respectively.
