Check out which companies are making headlines before the bell:
Restoration Hardware — The retailer of luxury home goods reported adjusted quarterly profit of 44 cents per share, 15 cents a share above estimates. Revenue was also above forecasts, although the company does point out that much of the beat was due to being able to ship products earlier than anticipated. That moved a portion of revenue and earnings forward into the most recent quarter.
JPMorgan Chase — Macquarie downgraded the bank's shares to "neutral" from "outperform," citing valuation, a challenging interest rate environment, and higher capital buffer requirements than its peers.
Mattress Firm — The mattress retailer reported adjusted quarterly earnings of 57 cents per share, 8 cents a share below forecasts. Revenue also fell shy of estimates. Comparable-store sales fell 1.1 percent during the quarter, but the company said it is making good progress in integrating its purchase of the Sleepy's chain.
Chipotle Mexican Grill — Chipotle settled cases with more than 100 customers who became ill after eating at the restaurant chain, according to lawyers for those customers. Terms of the settlements were confidential.
Twitter — Twitter remains in the news, amid speculation about its future. The New York Post reports that, contrary to rumor, investor Carl Icahn is not building a stake in the company. CNBC had reported earlier this week that no bids have come in for Twitter.
Williams Cos. — Williams shares are under pressure, following news that rival pipeline company Enterprise Products Partners is no longer interested in a merger with Williams. Enterprise said it did approach Williams about a potential deal, but found there was "no actionable path forward."
Korn/Ferry International — Korn/Ferry reported adjusted profit of 52 cents per share for its first quarter, 1 cent a share below estimates. The executive recruiter's revenue also fell below Street forecasts. Its current-quarter forecast is above consensus estimates, however, as it benefits from its recent acquisition of human resources consulting firm Hay Group.
Deutsche Bank — Deutsche Bank is expected to settle U.S. mortgage-backed securities cases for more than $2.4 billion, according to a German magazine, which said the Justice Department will send a formal notice to the bank next week.
Finisar — Finisar reported adjusted quarterly profit of 38 cents per share, 8 cents a share above estimates. Revenue also beat forecasts. The fiber optics company also gave a stronger-than-expected current-quarter forecast, as cloud services companies increasingly upgrade their networking hardware.
Advanced Micro Devices — AMD priced its recently announced secondary stock share offering at $6 per share, raising $600 million, compared with the originally expected $450 million. The chipmaker's $700 million offering of convertible notes also priced, with the initial conversion price at $8 per share.
HP Inc. — Samsung Electronics is considering selling its printer business to the former Hewlett-Packard, according to the Seoul Economic Daily newspaper.
Royal Caribbean, Norwegian Cruise Line — Bernstein began coverage on the two cruise line operators with an "outperform" rating, saying it is bullish on the cruise industry in general because it is concentrated on relatively few players and has strong demand characteristics, among other factors.
Zumiez — The action sports apparel seller reported a quarterly loss of 3 cents per share, 5 cents a share smaller than anticipated. Revenue was in line with forecasts. Zumiez does say its overall business continues to underperform its expectations, and it is focusing on managing its expense structure and executing its long-term plan.
