AMD Agrees to Buy Chipmaker Xilinx in $35 Billion All-Stock Deal (Bloomberg) -- Advanced Micro Devices Inc. agreed to buy Xilinx Inc. for $35 billion in stock, taking the chipmaker into more diverse and profitable markets and adding to its data center offerings.Xilinx investors will get 1.7234 AMD shares for each Xilinx stock they own. That values Xilinx at about $143 a share, 25% more than the closing price on Monday and 35% above the price before news of a possible deal was reported earlier in October.The deal is a coup for AMD Chief Executive Officer Lisa Su, creating a company with a larger research-and-development budget and a broader array of products to take on Intel Corp.Since taking over in 2014 when AMD was in crisis, she has slashed debt and overseen the development of more powerful processors. Revenue and profit have surged and the stock has soared. Now Su is using that currency to snap up a company with complementary products that generate steady cash flow.Some investors and analysts were concerned that AMD might borrow heavily to pay for a Xilinx acquisition, repeating costly mistakes from more than a decade ago.
