A supplier to Tesla Inc. ended up providing a tiny fraction of battery material the carmaker ordered almost three years ago, in part due to issues with the Cybertruck, according to a person familiar with the matter.

South Koreas L&F Co. disclosed this week that its 3.83 trillion won ($2.67 billion) supply contract with Tesla, first announced in February 2023, had been slashed to just 9.73 million won.

In a filing, L&F said the reason for the 99% reduction was a change in supply quantity.

The high-nickel cathode material that L&F was contracted to supply from January 2024 through this month was meant to be used in Cybertruck batteries, said the person, who asked not to be identified discussing sensitive business transactions.

Scant material was provided as the vehicles development was repeatedly postponed and consumers opted for other vehicles, including Teslas Model 3 sedan and Model Y sport utility vehicle, the person said.

The supply contract was also affected by broader policy and economic issues, including the elimination of Inflation Reduction Act subsidies, the person added. Tesla representatives didnt respond to an emailed request for comment.

L&F said in a statement that the revision was inevitable as schedules were adjusted in line with changes in the global electric vehicle market and battery supply conditions.

There have been no changes to shipments or customer supply of the companys flagship high-nickel product, L&F said, adding that shipments to major Korean cell manufacturers are proceeding smoothly.

Shares of L&F, which also supplies battery makers including LG Energy Solution Ltd., dropped 11% in Seoul on Tuesday. The stock has risen around 16% this year, trailing the 76% surge in the benchmark Kospi Index.

据知情人士透露，特斯拉公司的一家供应商最终仅提供了该汽车制造商近三年前订购的少量电池材料，部分原因是由于Cybertruck车型的问题。

韩国L&F公司本周披露，其与特斯拉于2023年2月首次公布的3.83万亿韩元（约合26.7亿美元）供应合同，已被大幅削减至仅973万韩元。

L&F在提交的文件中表示，供应量减少99%的原因是供应数量发生了变化。

据不愿透露姓名的知情人士透露，L&F公司根据合同从2024年1月至本月供应的高镍正极材料，原计划将用于特斯拉Cybertruck的电池生产。该人士要求匿名，因涉及敏感商业交易。

该知情人士表示，由于该车型的研发屡次延期，且消费者转而选择其他车辆（包括特斯拉的Model 3轿车和Model Y运动型多功能车），因此提供的资料非常有限。

该消息人士补充称，这份供应合同还受到更广泛的政策和经济问题影响，包括《通胀削减法案》补贴的取消。特斯拉代表未就电子邮件置评请求作出回应。

L&F在一份声明中表示，由于全球电动汽车市场和电池供应条件的变化导致时间表调整，此次修订是不可避免的。

L&F公司表示，其旗舰高镍产品的发货及客户供应均未发生变化，并补充称对韩国主要电池制造商的供货进展顺利。

周二，L&F公司在首尔的股价下跌11%，该公司也是LG新能源等电池制造商的供应商。今年以来，该股累计上涨约16%，但远低于韩国综合股价指数（KOSPI）76%的涨幅。
