According to the IPO paperwork Arm filed on Tuesday, Apple and Arm have a new agreement for semiconductor technology that “extends beyond 2040.”

The price range for Arm’s anticipated $52 billion initial public offering, which would be the biggest IPO in the United States this year, was revealed on Tuesday. SoftBank Group (9984.T), the firm that owns Arm, intends to sell 95.5 million American depository shares of the London-based company for between $47 and $51 each, according to a filing by Arm.

The computer architecture for the majority of smartphones in use today was developed by Arm, which it licences to companies like Apple and numerous others. Apple creates its own unique chips for its iPhones, iPads, and Macs using technology from Arm.

The two firms have a long history together; before the launching of their “Newton” portable computer in 1993, which utilised an Arm-based processor chip, Apple was one of the first companies that joined to form the company in 1990. The Newton was a failure, but Arm went on to rule mobile phone processors thanks to its low power consumption, which prolongs battery life.

Several significant technological firms, including Apple, contributed $735 million to Arm’s initial public offering on Tuesday. The news that Apple was one of the strategic investors that agreed to purchase shares was originally confirmed by Reuters last week.

The fact that Arm’s prior IPO registration materials, which were made public on August 21, did not mention the contract reported on Tuesday suggests that it was inked between then and September 5.

Beyond its filings, Arm declined to comment, and Apple did not immediately respond to a request for comment.
