Staples stock jumps on report Bain, others are considering buyout A report that several private equity firms -- including original investor Bain Capital -- are considering buying Staples Inc. pushed the office supply chain's stock up as much as 6.2% on Friday.

Now Staples employs nearly 90,000 people and has more than 2,000 stores, Stemberg said. Neither Framingham, Mass.-based Staples nor Bain Capital could immediately be reached for comment.
