U.S.-based asset management company Apollo Global Management has offered to make an investment of as much as $5 billion in Intel, Bloomberg News reported on Sunday.

Apollo has indicated in recent days it would be willing to make an equity-like investment of billions of dollars in Intel, the report said, citing a person familiar with the matter.

The news comes at a moment of weakness for Intel, which was once the most valuable chipmaker in the world, but whose shares have lost nearly 60% of their value since the start of the year.

Meanwhile, Chip giant Qualcomm made a takeover approach to rival Intel in recent days, according to people familiar with the matter, in what would be one of the largest and most consequential deals in recent years, the Wall Street Journal reported.

A deal for Intel, which has a market value of roughly $90 billion, would come as the chip maker has been suffering through one of the most significant crises in its five-decade history.

A deal is far from certain, the people cautioned. Even if Intel is receptive, a deal of that size is all but certain to attract antitrust scrutiny, though it is also possible it could be seen as an opportunity to strengthen the U.S. ’ s competitive edge in chips. To get the deal done, Qualcomm could intend to sell assets or parts of Intel to other buyers.

Intel shares gained 3.9% in premarket trading.
