Twitter Inc. on Friday blamed its ongoing battle to close its $44-billion acquisition by Elon Musk and a weakening digital advertising market for a surprise fall in quarterly revenue and a net loss.

The results come as Twitter has sued Musk for dropping his offer to buy the company, and is now preparing for a legal showdown in a trial set to begin in October. The deal uncertainty has worried Twitter’s advertisers and caused chaos inside the company.

Advertising revenue rose just two percent to $1.08 billion, missing Wall Street expectations of $1.22 billion, according to Refinitiv IBES data, Reuters reported Friday.

Total second-quarter (ending June) revenue, which also includes revenue from subscriptions, was $1.18 billion, compared with $1.19 billion a year earlier. Analysts were expecting $1.32 billion.

“Twitter is now in the unenviable position of convincing advertisers that its ad business is solid regardless of how its court battle with Musk ends, and its Q2 earnings show that the platform has its work cut it out for it to do that,” said Jasmine Enberg, principal analyst at research firm Insider Intelligence.

Twitter said its net loss was $270 million, or 35 cents per share, versus a profit of $65.6 million, or 8 cents per share, a year earlier. Its adjusted 8-cent loss missed expectations for a 14-cent adjusted profit.

Monetizable daily active users, a metric closely watched by investors and measures users who see advertising on Twitter, grew 16 percent to 237.8 million, but missed analyst expectations of 238.7 million.

The San Francisco-based company said bot and spam accounts represented fewer than 5 percent of users during the quarter, a figure it has repeated since 2013.

The company’s costs and expenses jumped 31 percent. Expenses related to the Musk deal totaled $33 million during the quarter, and also recorded $19 million in severance-related costs.

On Thursday, Snapchat parent Snap Inc. posted weak revenue growth and declined to make a forecast, citing “incredibly challenging” conditions as advertisers cut back spending.
