Rolls-Royce’s (LSE: RR) share price looks expensive on almost every standard measure right now. The stock trades at higher price-to-earnings, price-to-sales, and price-to-book multiples than its major aerospace peers on current and forward estimates. Even discounted cash flow analysis shows the stock screening as 29% overvalued. <\/p>\n
But crucially for savvy, long-term investors, this picture’s built entirely on guidance set by Rolls-Royce that it routinely beats. <\/p>\n
The reality is that Rolls-Royce’s margins and returns have undergone a structural shift, so the old ratios give an inflated valuation picture. Consequently, the shares may still be significantly undervalued once the company’s true earnings power, growth trajectory, and transformed profitability are fully reflected. <\/p>\n
Is this true of the latest results? <\/p>\n
Rolls-Royce’s 30 July-released H1 2026 numbers show the same valuation paradox playing out in real time. It issued conservative full\u2011year guidance earlier in the year, yet these results again blew past those forecasts. Underlying operating profit jumped 46% year on year to \u00a32.5bn, underlying operating margins rose sharply to 22.5%, and free cash flow surged 24% to \u00a32bn. <\/p>\n
This level of over\u2011delivery forced the company to raise its full\u2011year guidance to \u00a34.7bn\u2011\u00a34.9bn of operating profit and \u00a33.8bn\u2011\u00a34bn of free cash flow. <\/p>\n
These are well above the earlier forecasts that valuation models still rely on and imply an operational slowdown in Q2. That looks highly unlikely, given CEO Tufan Erginbilgi\u00e7’s comment that actions and investments the firm has made “will drive significant profitable growth to the mid-term and beyond.”\u00a0\u00a0 <\/p>\n
What will drive the next phase of growth? <\/p>\n
These results also underline how far the business has moved from its pre\u2011turnaround profile before Erginbilgi\u00e7 became CEO in 2023. <\/p>\n
Civil Aerospace continues to benefit from rising large\u2011engine flying hours, which reached 112% of 2019 levels in H1. Defence profitability is being lifted by record demand for equipment and technology modernisation programmes. And Power Systems is seeing strong, sustained margin expansion from demand for power linked to artificial intelligence data centres. <\/p>\n
One risk to growth is any sustained spike in capital expenditure requirements if data\u2011centre demand accelerates faster than expected. That could soften free cash flow in the near term. Another is any further sharp rise in oil price that could increase jet fuel prices and reduce large\u2011engine flying hours. <\/p>\n
Nevertheless, Rolls-Royce’s results’ trend implies that its higher margins and stronger cash generation aren’t temporary. They reflect a fundamentally transformed business model that legacy valuation ratios cannot capture. <\/p>\n
So where might the valuation go? <\/p>\n
Erginbilgi\u00e7 said recently that Rolls-Royce’s plan to power AI with its small modular nuclear reactors (SMRs) could make it the UK’s most valuable company. He estimates the world will need 400 SMRs by 2050 at a cost of up to $3bn (\u00a32.2bn) each. And that is another trillion-dollar+ market he wants and expects Rolls-Royce to dominate. <\/p>\n
HSBC’s currently the UK’s most valuable company, with a market capitalisation of around \u00a3260bn. If Rolls-Royce simply became as valuable as that, then its 8.26bn shares would be worth just over \u00a331 each. <\/p>\n
But if its SMRs business achieves the “trillion-dollar-plus [\u00a3730bn] market potential”\u00a0that Erginbilgi\u00e7 suggests, then that figure would rise to \u00a388 a share. <\/p>\n
In any event, I believe the stock has a lot further to rise, so will be buying more as soon as possible. <\/p>\n
