Should You Buy Arm Holdings Stock in August 2025? Here’s What You Need to Know

Arm Holdings is making waves again—but is it a smart play for your portfolio?

The semiconductor giant's stock has been on a rollercoaster, leaving investors torn between FOMO and skepticism. With AI demand surging and chip wars raging, Arm sits at the center of it all.

Bull case: Dominates mobile CPU architecture, rides the AI boom, and prints royalties like a central bank. Bear case: Valuation looks stretched, competition is fierce, and let's be honest—tech stocks love a good hype cycle.

One thing's certain: Wall Street analysts will keep flip-flopping their ratings while collecting fat commissions either way.

Arm's aggressive spending is taking a toll on its bottom line

Arm Holdings gets its revenue from selling licenses for its chip architecture. Semiconductor companies use this architecture to design and develop chips that go into various applications, ranging from smartphones to personal computers (PCs) to data centers. Arm also gets a royalty from the sale of each chip that's manufactured using its architecture and intellectual property (IP).

The company's revenue in the first quarter of its fiscal 2026 increased 12% year over year to $1.05 billion. This was driven by a solid jump of 25% in its royalty revenue, which accounted for 55% of its top line during the quarter. Arm attributed the increase in its royalty revenue to the growing adoption of its artificial intelligence (AI)-focused Armv9 architecture for manufacturing data center chips, and its compute subsystems (CSS), which are used to develop chips for custom applications.

However, the company's non-GAAP net income fell to $0.35 per share during the quarter from $0.40 per share in the year-ago period. Arm witnessed a sharp contraction in its operating margin during the quarter, which was a result of a big jump in its research and development (R&D) expenses. Specifically, Arm's R&D expenses increased by 34% on a year-over-year basis in fiscal Q1.

Arm management remarked on the company's latest earnings conference call that it will continue to invest aggressively in R&D. As pointed out by CEO Rene Haas:

We are continuing to explore the possibility of moving beyond our current platform into additional compute to subsystems, chiplets and potentially full end solutions. To ensure these opportunities are executed successfully, we have accelerated the investment into our R&D. These investments include expanding engineering delivery across multiple levels, adding to the already significant product investments we have made to date.

Arm's stance isn't surprising, since the company's architecture is now being widely used in data centers to build and deploy custom AI chips. The company says that there has been a 14x jump in the number of data center chips that are manufactured using its designs since 2021. That's not surprising, as major cloud computing companies such as,, and's Google are using its architecture to design custom AI silicon.

Evenhas used Arm's IP to design its Grace Blackwell server processors. Smartphone giantsand Samsung are also Arm's customers, using the British tech giant's chip architecture to manufacture AI-capable smartphone processors. The good part is that Arm's CSS licenses are now gaining traction among customers for developing smartphone, PC, and data center chips.

Arm says that it "signed three additional CSS licenses this quarter with existing CSS customers, including two for the data center and one for PCs, more than doubling our CSS licenses from a year ago." Importantly, Arm management points out that the royalty rate of its CSS license is double that of its Armv9 architecture.

So, it's easy to see why the company is looking to push the envelope on the product development front to provide end-to-end solutions to customers to help them design advanced chips capable of tackling complex workloads. Even better, Arm's spending on R&D is bearing fruit as the company is gaining impressive share in the data center and PC processor markets. Its smartphone revenue is growing at a faster rate than the end market, thanks to the use of its IPs to manufacture processors for flagship smartphones.

However, Arm's R&D spending is going to keep its bottom line under pressure. The company's earnings estimate of $0.33 per share for the current quarter (at the midpoint of its guidance range) is lower than the $0.35 per share consensus estimate. The positive thing to note is that earnings WOULD increase in double digits from the year-ago period's reading of $0.30 per share at the midpoint, with revenue expected to increase by more than 25%.

But then, analysts are expecting an increase of just 5% in Arm's earnings this year, which can be attributed to the investments that it is making to secure its long-term growth. That could be a problem considering its expensive valuation.

The stock is richly valued, but the long-term picture seems bright

Arm trades at an expensive 208 times earnings as of this writing. It's easy to see why investors hit the panic button following its latest quarterly report. The decline in its earnings didn't justify the rich valuation, and the single-digit earnings growth that it's expected to deliver this year doesn't help matters either.

However, Arm's forward earnings multiple of 76 is way lower than its trailing multiple. That's not surprising, as its earnings growth is expected to accelerate nicely over the next couple of years.

Its forward price-to-earnings (P/E) ratio based on its fiscal 2028 earnings is even lower at 49 (calculated using the earnings estimate of $2.86 per share provided in the above chart). Moreover, there is a good chance that Arm's earnings growth could eventually turn out to be better than expected, thanks to the higher royalty from its CSS licenses and the Armv9 architecture.

That's why growth investors can consider buying Arm stock on the dip. Its bottom-line pressure shouldn't last for long, thanks to the secular growth of the lucrative end markets that it's serving.
