Tesla CEO Elon Musk missed the regulatory deadline for announcing his recent purchases of Twitter stock, raising questions about whether he made more than $150 million by hiding his ownership stake while buying more shares.

A filing this week revealed Musk purchased a 9.2% stake in Twitter, making him the largest shareholder. He also joined the company’s board. A subsequent filing amended his ownership to 9.1%.
