Arm Holdings Rises in After-Hours Trading on Expanded IBM Partnership

Arm Holdings PLC's stock was a hot name Wednesday evening.

Shares of the British semiconductor and software design company rose 4.76% to $263 in after-hours trading on Wednesday.

In regular trading, ARM gained 3.93%, closing at $251.06.

Rally Driven by Arm-IBM Partnership Announcement

The rally stems from Arm's announcement earlier this week of an expanded partnership with IBM.

According to a blog post by Mohamed Awad, Executive Vice President of Arm's Cloud AI division, under the expanded partnership, IBM will bring Arm architecture to future IBM Z and LinuxONE mainframe systems, marking the first dual-architecture processor introduced under this collaboration.

IBM Z and LinuxONE are enterprise-grade server families designed for security, large-scale operations, and mission-critical computing. However, they primarily differ in approved operating systems and workloads.

Awad wrote, "Each processor core is designed to natively execute both IBM and Arm instructions," enabling Arm-native Linux environments to run in parallel with z/OS and existing Linux applications.

The expanded partnership follows Arm's better-than-expected fiscal first-quarter results reported in late July.

The company beat analyst expectations on both revenue and earnings per share. Arm reported quarterly earnings per share of 45 cents, versus the 40-cent consensus estimate. Its revenue came in at $1.29 billion, also surpassing analysts' forecast of $1.26 billion.

Arm is also a co-development partner with Meta on the Arm AGI CPU, marking Arm's first self-designed data center chip after 35 years of pure licensing business.

Raymond James raised its price target on Arm from $565 to $641 on Tuesday, maintaining an Outperform rating.
