> To tack on to this, why would investors want to own WeWork bonds vs equity in the company?
Because if the company goes bankrupt, bond-holders get paid before shareholders.
As such, bond-holders are always in a less-risky position. You'll always recoup some of your money during bankruptcy. (Don't estimate the value of the shelves and furniture!) While shareholders only get some $$ if the bonds are fully paid off.
> In the case where bond holders do well, wouldn't shareholders do better?
Not always. Bond holders will do well if the share-price stays steady or even negative. The company may stagnate over the next 7 years, at which point holding bonds would have been a better investment. The company is legally obligated to pay bondholders at its highest priority, until bankruptcy.
The Bonds aren't sold yet, but will likely be in the range of 4.5% to 5% (depending on market conditions during the sell-date). Over 7 years, the company needs to grow its share price by 36% for equity to beat a 4.5% bonds, or 40% to beat the 5% bond. Doable for sure, but its not too hard imagining a situation where they fail this benchmark and the bonds end up the superior choice.
For example: GNC's stock price doesn't help its shareholders, but the bond-holders would be doing fine.
