Jeff Bezos filed a statement with federal regulators indicating his sale of nearly 12 million shares of Amazon stock worth more than $2 billion.

The Amazon executive chairman notified the U.S. Securities and Exchange Commission of the sale of 11,997,698 shares of common stock on Feb. 7 and Feb. 8.

The collective value of the shares of Amazon, which is based in Seattle where he founded the company in a garage about three decades ago, was more than $2.04 billion, according to the listed price totals.

The stocks were grouped in five blocks between 1 million and more than 3.2 million.

In a separate SEC filing, Bezos listed the proposed sale of 50 million Amazon shares around Feb. 7 with an estimated market value of $8.4 billion.

GM hires battery expert

General Motors Co. has hired Kurt Kelty, a battery expert and former Tesla Inc. executive, as vice president of batteries, the automaker said.

In the newly created role, Kelty will report to GM President Mark Reuss.

Kelty is charged with developing a new end-to-end battery technology strategy, which will include the sourcing of raw materials, investment in new battery technologies and end-of-use opportunities.

His team is responsible for bringing together GM’s battery development resources to quickly deliver profitable, lower-cost, higher-performing EVs to customers at scale.

“The foundation that GM has established coupled with Kurt’s exceptional battery expertise in leading battery chemistry development, establishing partnerships, building out supply chains and partnering closely with teams that have developed leading battery systems will help us achieve our electrification goals and position GM as a leader in EV technology,” Reuss said in a statement late last week.
