What happened

Shares of aerospace supplier Aerojet Rocketdyne Holdings Inc. (NYSE: AJRD) fell as much as 16.4% on Thursday after the company announced a debt offering. At 3:30 p.m. EST shares were still down 10.9%.

So what

Now what

Investors also need to keep in mind that this may help the company's operations long-term. If the interest payment is lower than the revolver it's replacing, interest costs could go down and free cash flow could go up. But that's the trade-off for offering convertible debt, something investors aren't bullish on today.
