SPCE, -0.73 is seeking to sell up to 300 million worth of shares in an at the market offering, as the space-tourism companys cash reserves dwindle and the launch of its first commercial space is pushed back. In a filing with the Securities and Exchange Commission on Thursday, Virgin Galactic revealed that it had entered into a distribution-agency agreement with Credit Suisse, Morgan Stanley and Goldman Sachs to raise money for general corporate purposes, including working capital, general and administrative matters and development of its spaceship fleet and other infrastructure to scale its commercial operations.
