In an SEC filing Friday evening, the electric-car maker said it incurred $430.7 million of costs for the massive Nevada-based battery plant as of the end of June.
The Gigafactory may also take longer than anticipated to come online, the electric carmaker said in a filing on Friday.
Tesla, which is buying solar panel installer SolarCity Corp for $2.6 billion in shares, unveiled the massive battery factory, the Gigafactory, in Nevada last week.
