Intel said on Wednesday it would sell one-fifth of its stake in IMS Nanofabrication to private equity firm Bain Capital in a deal valuing the Austrian producer of chipmaking tools at about $4.3 billion.
Intel's stake sale of 20 per cent was valued at $860 million, according to Reuters calculations.
IMS, which was acquired by Intel in 2015, makes equipment that are critical for companies that make chips.
It has delivered a significant return on investment to Intel while growing its workforce and production capacity by four times, Intel said.
Bain Capital's investment in IMS will put it in a position to capture significant market share for its tools that are being widely adopted by chipmakers, Intel said.
