Why Rivian Shares Popped on Friday

Looks like some hopeful news for RIVN bag holders like me.
From the article: "Shares jumped as much as about 6% and were still higher by 2.4% as of 12:35 p.m. ET. In early March Rivian announced it would adjust its expansion plans that included constructing a new multibillion-dollar plant in Georgia. That new facility would produce Rivian's R2 second-generation vehicle platform, the company originally said. But Rivian shifted gears as the pace of EV sales growth has slowed.
Rivian's next-gen plans get a boost Rivian said in March it would save $2.25 billion in capital expenditures, product development investment, and supplier sourcing opportunities from the decision to begin building the R2 in Illinois instead. Now, an $827 million grant from Illinois' Department of Commerce & Economic Opportunity will help expand the existing plant from an annual capacity of 150,000 to 215,000 units. That is worth more than half the $1.5 billion the company said it will spend to expand the plant."
