In particular, however, there is one notable source that emphasizes Panasonic's role: Tesla's SEC filings. Quoting TSLA's 2015 10-K[1]:
We believe that the Gigafactory will allow us to achieve a significant reduction in the cost of our battery packs once we are in volume production with Model 3. The total capital expenditures associated with the Gigafactory through 2020 are expected to be $4 to $5 billion, of which approximately $2 billion is expected to come from Tesla. Panasonic has agreed to partner with us on the Gigafactory with investments in production equipment that it will use to manufacture and supply us with battery cells. We have a supply agreement with Panasonic that, among other things, allows us to purchase a minimum of 1.8 billion lithium-ion battery cells at preferential prices that we intend to purchase from 2014 through 2017. We have agreed to prepare and provide the land, buildings and utilities, invest in production equipment for battery module and pack production and be responsible for the overall management of the Gigafactory.
