Check out which companies are making headlines before the bell:
Alcoa — The aluminum producer reported adjusted quarterly profit of 7 cents per share, 5 cents a share above estimates. However, revenue missed Street forecasts, and Alcoa said it would cut up to 2,000 jobs in the wake of continued weak aluminum prices.
Avon Products — Piper Jaffray cut its rating on the cosmetics seller to "neutral" from "overweight," saying the shares are now fairly valued following the rally that occurred after the company's January analyst day.
Starbucks — The coffee chain's stock was downgraded to "hold" from "buy" at Deutsche Bank, pointing to a "premium" valuation and "lofty" investor expectations.
Juniper Networks — Juniper said it expected to report first quarter profit of 35 cents to 37 cents per share, well below estimates of 45 cents a share. The maker of networking gear also said revenue would be below forecasts, due in part to weak corporate demand.
AbbVie — The drugmaker received accelerated Food and Drug Administration approval for a new treatment for patients with chronic lymphocytic leukemia.
Fastenal — The maker of construction supplies missed estimates by a penny a share, with quarterly profit of 44 cents per share. Revenue also missed Street forecasts. The company's core fastener business continued to contract, and its overall sales growth has slowed as well.
L Brands — The Victoria's Secret parent was downgraded to "neutral" from "buy" at Goldman Sachs, which also removed the stock from its "Conviction Buy" list. Goldman is still upbeat on the company long term, but feels last week's announced restructuring at Victoria's Secret could dampen near-term sales growth.
United Continental — The airline is likely to strike a deal with activist investors within the next week or so. Sources tell CNBC that a deal would include more new directors for the airline's board as well as the possibility of a new independent chairman.
Nomura Holdings — Nomura will cut 500 to 600 jobs, primarily in Europe, as the brokerage firm tries to stem several years of red ink.
Ford — Ford's F-150 Super Cab pickup truck received a "top safety pick" rating in new testing by the Insurance Institute for Highway Safety. It was the only large pickup truck model to receive that rating.
Viacom — Viacom controlling shareholder Sumner Redstone opposes a plan by CEO Philippe Dauman to sell a minority stake in the company's Paramount Pictures movie studio, according to The Wall Street Journal.
Boeing — Boeing has opened negotiations to sell its jets in Iran, following the lifting of nuclear sanctions in that country.
Costco — Costco is telling shareholders to reject a "mini-tender" offer by private equity firm TRC Capital to buy up to one million shares of the warehouse retailer at $149.50 per share.
Goldman Sachs — Goldman may wind up paying only $4 billion for its $5 billion settlement announced yesterday once tax benefits are taken into account, according to The New York Times DealBook.
