Jiwei Network News (Text/Zhang Lin) On November 19, 2021, Shenzhen Amperon Technology Co., Ltd. (hereinafter referred to as "Amperon") replied to the Shenzhen Stock Exchange on "analyzing and disclosing whether there is a large difference between the gross profit margin of the oxygen sensor and the core and the average gross profit margin of the industry, and disclosing the reasons for the sharp decline in the direct material cost of the oxygen sensor in 2019", and Amperon disclosed as follows:
1. The oxygen sensor and the core cannot be directly compared with the average gross profit margin of the industry
As the core component of the engine management system of fuel vehicles, the oxygen sensor has no public and comparable market price. In addition to Amperon, the domestic manufacturer Changzhou Liande can provide related products. Changzhou Liande is not listed, and the relevant data of oxygen sensor price and gross profit margin are not disclosed. The oxygen sensor produced by Bosch, a major overseas manufacturer, and Japan Special Ceramics Co., Ltd. 1-157 Co., Ltd. is used for engine management system, and the relevant data of the price and gross profit margin of the oxygen sensor are not disclosed. The oxygen sensor core is a sensitive material for the oxygen sensor to perceive oxygen concentration, is the core component of the oxygen sensor, and has no reference to the market price and gross profit margin.
Therefore, it is impossible to compare whether the gross profit margin of Amperon's oxygen sensor and core is significantly different from the industry average gross profit margin.
2, the reason for the sharp decline in the direct material cost of oxygen sensors in 2019
The main reason for the sharp decline in the unit direct material cost of oxygen sensors in 2019 is the increase in the proportion of sales of automotive concentration and difference lambda sensors in 2019, and its unit direct material cost is lower than that of other models such as automotive wide-area oxygen sensors. In addition, the unit price of the main raw material hexagonal base and high temperature line procurement in the assembly stage of the oxygen sensor has decreased, which has a certain impact on the decline in the direct material cost of the oxygen sensor in 2019.
The influence of the product model structure
In 2018 and 2019, the unit direct material cost of oxygen sensors and major models is as follows:
Automotive wide-area lambda sensors and automotive concentration differential lambda sensors are two types of oxygen sensor products mainly sold by Amperon. The direct material cost of the two types of products is quite different, and the unit direct material cost of the automotive wide-area lambda sensor is about 40 yuan / one, while the unit direct material cost of the automotive concentration type oxygen sensor is about 20 yuan / one. In 2019, the direct material cost of the automotive concentration difference oxygen sensor accounted for 97.74%, which was significantly higher than that of 2018, which reduced the direct material cost per oxygen sensor in 2019.
Impact of raw material procurement costs consumed at the stage of assembly into a lambda sensor from the core
The main raw materials consumed in the process of assembling the oxygen sensor from the oxygen sensor core hexagonal base and high temperature line have a certain impact on the direct material cost of the oxygen sensor, and its procurement costs in 2018 and 2019 are as follows:
Amperon's production and sales of oxygen sensors in 2019 have increased significantly, and the number of raw materials such as hexagonal bases and high-temperature wires purchased from suppliers has also increased significantly, and Amperon has negotiated with suppliers to reduce the purchase price, which has a certain impact on the decline in direct material costs of oxygen sensors in 2019.
