Check out the companies making headlines after the bell Tuesday:

Shares of Chesapeake Energy dropped in extended-hours trading. The energy company is the worst ranked stock in the S&P 500 so far, down nearly 77 percent year-to-date.

Fairchild Semiconductor stock climbed higher in after-hours trading. On Tuesday, the company acknowledged receipt of an unsolicited proposal from an unnamed bidder to acquire all of the outstanding shares of common stock of Fairchild for $21.70 per share in cash. In November, Fairchild entered into an agreement of merger with ON Semiconductor under which ON agreed to acquire all of the outstanding shares of Fairchild common stock for $20 per share in cash. Fairchild's board of directors said it has not changed its recommendation in support of the merger agreement with ON.

Adobe Systems stock rose after the bell. The after-hours push puts the software company above its 52-week high.

Staples stock also edged higher in after-hours trading. The office supply company is currently embroiled in a legal spat with the Federal Trade Commission regarding a $6.3 billion merger with smaller office supply retailer Office Depot.

Allergan stock inched lower after the bell. According to Dealogic data, the pharmaceutical company's pending merger with Pfizer marks 2015's largest M&A deal, followed by Anheuser-Bush InBev's deal with SABMiller.

Shares of Freeport-McMoRan dipped slightly lower in extended-hours trading. The metals and mining giant is part of a sector that has fallen 2.54 percent this week. On Monday, Executive Chairman James Moffett resigned from the company.

Pep Boys stock also dropped Tuesday; Bridgestone Americas announced that its subsidiary, Bridgestone Retail Operations, will not counter activist investor Carl Icahn's offer to acquire the auto-parts company. Icahn is the second-largest shareholder with more than 11 percent of the company.
