Arm, the most exciting company to come out of the UK since… Who knows? It’s been a while since the words "UK" and "exciting" were even in the same sentence. Arm is involved in the semiconductor ecosystem as a designer for things like processors. It then sells and licenses its fancy designs to tech companies with a whopping 99% of smartphones using Arm-based processors.
Its recent initial public offering (IPO) was a success and reignited investor interest - even though it decided to list in the US instead of the UK (we’re not bitter about it, honestly). With a surge in AI and cloud computing, demand for Arm’s technology is growing. Buying Arm shares is a way to gain exposure to the backbone of modern computing, but competition is heating up and it’s reliant on major licensees like Apple and Nvidia.
Find the cheapest way to buy Arm shares with our calculator. Bear in mind that both exchange rates and share prices fluctuate in real time, so the costs estimated here are just a guide (refer to platforms themselves for availability and exact pricing).

"It's impossible to predict with any degree of certainty. Still, if we look at past IPOs, there's likely to be plenty of immediate volatility as the market attempts to price Arm shares.
Once the dust has settled and the hype dies down, Arm will be treated just like any other stock. Its finances will become much more public, and investors can dig into the company to decide if the shares are worthy of the price tag.
The Arm IPO was a great springboard, but it's now up to the company to perform and showcase that it deserves to be held in such high esteem among the other major semiconductor stocks. "

Valuing a stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of overall performance. However, analysts commonly use some key metrics to help gauge value. Check out the Arm P/E ratio, PEG ratio and EBITDA.
Arm's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 214x. In other words, Arm's shares trade at around 214x recent earnings.
That's relatively high compared to, say, the trailing 12-month P/E ratio for the United States stock markets on average as of March 2025 (25.37). The high P/E ratio could mean that investors are optimistic about the outlook for the shares or simply that they're over-valued.
However, Arm's P/E ratio is best considered in relation to those of others within the industry or those of similar companies.
Arm's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 1.734. A PEG ratio over 1 can be interpreted as meaning shares are overvalued at the current rate of growth, or may anticipate an acceleration in growth.
The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into Arm's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.
However, it's sensible to consider Arm's PEG ratio in relation to those of similar companies.
Arm's EBITDA (earnings before interest, taxes, depreciation and amortisation) is $992.8 million (£722 million).
The EBITDA is a measure of Arm's overall financial performance and is widely used to measure a its profitability.
To put that into context you can compare it against similar companies.
Contrary to popular belief, Arm doesn't actually make chips (semiconductors). Arm creates designs for chips and then sells or licences the intellectual property (IP) to big tech firms. So it's not a manufacturer, more of a research company.
However, this is partly what makes Arm so valuable. It doesn't matter whether a phone is Android or iOS, Samsung or Apple, every piece of hardware can potentially use Arm's chip designs.
This is why you'll see crazy stats showing that Arm chips can be found in over 90% of smartphones worldwide. The ability to customise Arm chips for different firms and devices makes them a very unique semiconductor business.
