The equity is worthless here.
Bond maturities aren't the problem, the problem is they can't file financials with the SEC which is a violation of their bond covenants. They have been operating under a waiver / grace period for several months and are in the process of negotiating an in court restructuring (Chapter 11).
Management swears the financial issues are limited to accrual accounting related to several large acquisitions they did and is not a cash receipt / disbursement problem, but the market is probably rightly suspicious of this.
They have an LOI (or PSA) signed for their European infrastructure business, this part of the Company is not asset-lite, that will fetch them about $2 billion. Proceeds will be used to repay debt at European subsidiaries as well as a bridge loan they obtained from bank lenders. Bonds are suing the Company saying they actually have a priority claim on European asset sale proceeds. If they slip into bankruptcy this issue becomes much more complicated. At the end of the day the point is that zero of this benefit will accrue to the equity.
Absent the European infrastructure, this is not a good business you'd want to own which is another problem as reflected by the price of the bonds.
There may be some option value in the equity worth punting around based on process-related catalysts, but I would stay away or invest elsewhere in the capital structure.
