On July 28, Tesla is rapidly transforming from a rising star in the automotive industry to a mature market leader, and its performance data can provide proof. The electric vehicle manufacturer achieved a record profit of $1.1 billion in the second quarter, more than twice the net profit of the first quarter ($438 million) and more than 10 times that of the same period last year. So how did Tesla do it p> < p > < / P > < p > this is mainly due to two aspects: first, in terms of automobile sales, Tesla produced and delivered more than 200000 vehicles in the second quarter, a record high. The second is to reduce costs. The company has greatly reduced factory costs and increased its operating profit margin to 11%, which is in line with competitors such as general motors p> < p > in addition, Tesla has generated $354 million in revenue by selling carbon credits to other carmakers, which use carbon credits to meet environmental standards and avoid huge fines. But compared with the past, Tesla's dependence on carbon score income is much lower. This is a good sign because other companies are starting to produce more of their own electric vehicles, reducing the demand for carbon credits p> < p > nevertheless, Tesla's share price may still fluctuate sharply in the coming months, putting pressure on its market value of nearly $634 billion. Ryan Brinkman, an analyst at JPMorgan Chase, said: "Tesla's overestimation leaves little room for imperfect execution. We do see some signs of imperfection." p> < p > Elon Musk, CEO of Tesla, also warned that the shortage of computer chips that dragged down the entire automotive industry would continue to cause problems. "Although we are producing cars at full speed, the global chip shortage is still quite serious," he told investors. For the rest of this year, our growth rate will be determined by the slowest part of the supply chain. " p> < p > Tesla postponed the production plan of electric truck semi to 2022, "due to limited battery supply and challenges in the global supply chain". The German company cybertruck is making every effort to delay the launch of its new pickup near Austin and Texas. As competitors begin to produce more electric vehicles, it is important to expand production capacity, which may erode Tesla's market share p> < p > Bank of America analyst John Murphy said in a report to investors: "although Tesla is clearly a pioneer in the electric vehicle market and has successfully distinguished itself, its business environment is becoming increasingly crowded from a vacuum."( Small) < / P > < p >
