• Boeing Co. is preparing to raise up to $25 billion to strengthen its financial position amidst a major strike and a series of operational challenges. The aerospace giant filed with regulators on Tuesday to offer a combination of bonds and shares, known as a shelf registration. This move aims to bolster Boeing’s balance sheet and improve its cash access as it seeks to avoid being downgraded to junk status by credit rating agencies, which would lead to higher borrowing costs.

• The additional capital would provide Boeing with leverage in its negotiations with striking workers who have halted production at key facilities near Seattle. Union members are demanding higher wages and the reinstatement of pensions, and talks recently stalled again as both sides held firm on their positions. Earlier this month, Bloomberg reported that Boeing was considering raising at least $10 billion, which, if realized, could become the largest capital raise by a public company since Saudi Aramco’s $12.3 billion sale in June.
