Are Rolls-Royce shares still a once-in-a-decade opportunity?

Since Rolls-Royce shares reached a bottom in 2022, they have delivered life-changing returns to many. Are they still a once-in-a-decade opportunity?

If an investor put £10,000 into Rolls-Royce (LSE:RR.) shares on 30 September 2022, at just 69.59p apiece, they would have £174,091 today.

The company’s shares exploded by a phenomenal 1,640.9% in that period. That’s an incredibly impressive run-up, which would have changed the lives of many investors.

However, while it certainly was then a once-in-a-decade opportunity, is it still so?

Let’s be realistic

The market capitalization of the aircraft engine manufacturer when its shares started this great run was around £5.8bn. The market cap now is £99.5bn.

Even if it didn’t match its previous performance, and its shares just went up 10 times, the firm would almost be a trillion-pound company.

Its price-to-earnings (P/E) ratio of 36.8 on 2026’s projected earnings is already very expensive. But even if it were to match that high P/E as a trillion-pound company, it would still need to make £27.2bn in profit.

With trailing 12-month revenue of only £19.5bn in comparison, that’s a very big ask for the firm right now. And with its 29.6% profit margin over the same period, it would need to generate £91.7bn in revenue to make this profit. This is almost five times the current amount.

A compounded annual growth rate of 16.7% is required to achieve this over the next decade. With revenue up by 7% in its latest half-year results, it’s nowhere close to making this happen.

And its profit margin has been boosted recently by significant financing income, meaning the growth rate needed from operations may be much higher.

At the same time, it needs to maintain the same expensive valuation.

I believe it’s highly unrealistic for the company to do all of this.

That’s why I don’t believe the company’s shares are a once-in-a-decade opportunity anymore. However, I still believe Rolls-Royce shares could be a great investment in the long term.

Still plenty to like

There are still plenty of reasons to like the aircraft engine manufacturers’ shares, though.

These include the continued strong performance of its civil aerospace division since the pandemic, and the unfortunate reality that global conflicts seem to be on the rise, which will be beneficial to Rolls-Royce’s defence division.

But the one area on which I want to focus my discussion on is the company’s potential with small modular reactors (SMRs).

SMRs are a technology that could revolutionise the way nuclear energy is deployed. It turns the power source into a commoditised factory-built product. This is much cleaner for the environment than traditional nuclear energy plants.

It should be noted that SMR technology is untested in its effectiveness, so it would be very bad for the company’s share price if it were found to be ineffective.

However, this aside, the opportunity is anticipated to be massive. With 400 SMRs expected to be needed by 2050, costing $3bn each, this could be a trillion-dollar industry.

Rolls-Royce is already making huge strides in this space. It already has agreements with the UK and the Czech Republic to supply them with SMRs.

Ultimately, while no longer a once-in-a-decade opportunity, if the company continues executing well in this industry, its shares could be a big winner for investors over the long term. Therefore, they should consider buying them.
