Japanese chipmaker Renesas strikes $5.9 billion deal to buy software company Altium

Japanese semiconductor firm Renesas Electronics said Thursday that it would acquire Sydney-listed software company Altium for 9.1 billion Australian dollars ($5.89 billion) in cash, as it seeks to streamline its electronics design process.

Renesas said it would pay AU$68.50 per share, representing a 33.6% premium to Altium's closing price of AU$51.26 on Wednesday.

Koll said "corporations have almost $5 trillion of cash reserves/retained earnings on their balance sheets combined with de-facto zero interest rate funding from the government" which is helping Japan Inc to fund acquisitions and the build-up of a comprehensive chips ecosystem.

"It is perfectly reasonable to forecast that by 2028-2030, Japan Inc will own and operate as much as one-third of the global chip-making ecosystem," which is more than double from its current share, Koll said.

The deal has been unanimously approved by the board of both companies but its completion is subject to approvals from Altium shareholders, Australian court and regulators, Renesas said.

"Having worked closely with Renesas as a partner for nearly two years, we are excited to be part of the Renesas team as we
