Probably someone wrote naked calls and is afraid he's going to have them exercised against him.

Possibly arbitrage by a Market Maker. For example I see that the last sale of the Dec 25 options was at $1.20 while the current share price was at $25.25. A Market Maker could pick up a thousand contracts, exercise them and sell the stock at a $.05 per share profit (x 100,00 shares = $5000.00 profit).
