Elon Musk’s SpaceX lost more than a quarter of a billion dollars in 2015 after a botched cargo run to the International Space Station and the subsequent grounding of its Falcon 9 rocket fleet, Reuters reports citing The Wall Street Journal.

The accident derailed SpaceX’s expectations of $1.8 billion in launch revenue in 2016, an analysis of the privately held firm’s financial documents showed, according to the Journal, which said it had obtained the documents.

SpaceX declined to comment on the Journal’s report.

In a statement emailed to Reuters, SpaceX Chief Financial Officer Bret Johnsen said the company “is in a financially strong position” with more than $1 billion in cash reserves and no debt.

SpaceX, owned and operated by Musk, who also is chief executive of Tesla Motors Inc (TSLA.O), is aiming to return to flight on Saturday following a second Falcon 9 accident on Sept. 1.
