NEW YORK, Feb 11 (Reuters) - U.S. stock index futures were little changed on Wednesday, after the S&P 500 climbed to its highest level of the year and ahead of a meeting of euro zone finance ministers to discuss plans for Greece’s debt.
* Greek Prime Minister Alexis Tsipras comfortably won a confidence vote on his plan to cancel a deeply unpopular bailout program ahead of the meeting of euro zone finance ministers. EU leaders will meet on Thursday to discuss the Greek debt crisis.
* The benchmark S&P index rose more than 1 percent on Tuesday on hopes negotiations would result in a deal to help resolve Greek debt problems and stabilize the euro zone. The index is now down 1.1 percent from its latest record high set on Dec. 29.
* PepsiCo rose 2.6 percent to $100.50 before the opening bell after the maker of soft drinks and Tropicana beverages posted quarterly results.
* Despite some high-profile earnings misses from large multinational companies, largely as a result of dollar strength, Thomson Reuters data through Tuesday morning showed 72.7 percent of the 341 S&P 500 components that have reported earnings topped expectations, above the 69 percent beat rate in the past four quarters.
* Apple Inc will buy about $850 million of power from a First Solar plant in California to cut its energy bill and supply energy to the company’s campus, offices and stores in the state. Apple shares edged up 0.3 percent to $122.38 in premarket while First Solar climbed 2 percent to $49.50.
* Rite Aid rose 4.9 percent to $7.95 in premarket after the drugstore operator said it would buy privately held pharmacy benefit manager EnvisionRx for about $2 billion.
* Pier 1 Imports tumbled 31.4 percent to $11.65 in premarket after the furniture retailer cut its 2015 profit forecast, citing weak sales in January and February.
* After the closing bell, earnings are expected from Applied Materials, Cisco Systems, TripAdvisor and Whole Foods Market
* European shares slipped, with investors uneasy over the euro zone ministerial meetings on Greece’s debt crisis while Asian markets edged lower with Japanese markets closed for a public holiday.
