Several sources confirm that Apple is in talks to buy 3-D sensing company PrimeSense, following a report in the Israeli publication Calcalist. However, those sources stressed that the deal is not yet done, and that its reported valuation would not represent a huge win for investors. Calcalist put the value of the deal at $345 million. Sources said that talks are “close” to complete, but are hung up on end-game issues like liquidity preferences — in other words, who gets paid first. One also said the price could be slightly higher than reported, on the order of $20 million more. Sources noted that the expected value of the deal would not be a big jump over where investors had recently valued the company, which was apparently at about $250 million. One source with knowledge of the situation said it was “a bit of a letdown, but a decent outcome.”
