NEW YORK ( TheStreet) -- Bristol-Myers Squibb ( BMY) plans to acquire Inhibitex ( INHX) for $2.5 billion. Bristol-Myers' all-cash tender offer values Inhibitex at $26 a share, or more than two-and-a-half times the company's closing stock price on Friday of $9.87. For all that cash, Bristol-Myers gains control of Inhibitex's INX-189, a pill in phase II studies which has the potential to become a component in the first all-oral therapies against hepatitis C. Bristol-Myers shares were gaining 1.6% to $34.76, while Inhibitex shares were soaring 150% to $24.65 in premarket trading on Monday. Achillion ( ACHN), in other hepatitis C drug news, said preliminary results for its ACH-1625 treatment for genotype 1 treatment-naive hepatitis C showed complete early virologic response after 12 weeks. The shares were climbing 15% to $9.08 in premarket trading. Alcoa ( AA) posts results after the closing bell Monday, marking the unofficial start to the earnings season. The aluminum maker last week said its global smelting capacity will be reduced by 12% after the closure of certain plants. Alcoa said it would record fourth-quarter restructuring charges of $155 million to $165 million. Analysts' expectations on Alcoa's results vary from a loss of 5 cents a share to a profit of 1 cent. Shares were up 0.9% to $9.24 in premarket trading. Lions Gate Entertainment ( LGF) is close to buying Summit Entertainment, the maker of the Twilight series of vampire movies.

Netflix ( NFLX), which advanced 25% in the first week of trading in 2012, will launch its streaming video service in the U.K. and Ireland on Monday. The video-streaming service will offer a one-month free trial in order to compete in a market currently dominated by Amazon's ( AMZN) Lovefilm and British Sky Broadcasting Group. Netflix has already said it will lose money in 2012 because of the expansion across the Atlantic. In response to Netflix's plans to offer unlimited video content for 5.99 pounds a month, Lovefilm announced Monday plans to offer unlimited streaming service for an introductory price of 4.99 pounds a month.
