Boeing is looking to raise up to approximately $19 billion in a stock offering as the aerospace giant, which is dealing with a contentious strike, faces liquidity issues and tries to raise cash.

Boeing Co. said Monday that it will offer 90 million shares in common stock and $5 billion in depositary shares.

The company said it plans to use the net proceeds for general corporate purposes, which may include repaying debt, additions to working capital, capital expenditures, and funding and investments in its subsidiaries.

Fitch Ratings said Monday that the offering supports debt repayment and increases financial flexibility, alleviating the risk of a downgrade. The agency said that it continues to evaluate Boeing’s ability to resolve its labor negotiations and regain operational momentum. It rates Boeing “BBB-,” the lowest investment-grade rating.

Last week Boeing factory workers voted to reject the company’s latest contract offer and to continue a six-week strike that has halted production of its bestselling jetliners.

Local union leaders in Seattle said 64% of members of the International Association of Machinists and Aerospace Workers who cast ballots voted against accepting the proposal.

The strike has deprived the company of much-needed cash that it gets from delivering new planes to airlines. On Wednesday, the company reported a third-quarter loss of more than $6 billion. Boeing hasn’t had a profitable year since 2018. Chief Financial Officer Brian West said the company will not generate positive cash flow until the second half of next year.

Shares of Boeing have lost 40% of their value in the year to date.
