To answer this question, it is first worth taking a look at the chart.
The share has lost around 20% since its high of around €260 (during the sell-off at the start of the Iran war), but has now picked up again and is currently trading at €248.35. $SIE (+0,88%)
According to the share finder, however, there is a clear overvaluation, meaning that the share price is more than 50% above fair value (€155). We will therefore review this case to see whether we are buying an overpriced company or a very interesting value pick.
What is Siemens actually doing?
1. digital industries: global market leader for factory automation. Siemens supplies the software and AI with which factories (e.g. BMW or Coca-Cola) produce autonomously and efficiently.
2. smart infrastructure: The brain of modern buildings and power grids. They ensure that data centers (AI boom!) are cooled and that renewable energy flows stably into cities.
3 Mobility: Everything to do with rail transportation. From ICE trains to digital signaling technology that allows trains to run every minute without the need for new tracks.
2. the figures
In-depth check of the current 2026 figures
1. sales growth (7-8%): Siemens revised its forecast upwards in February 2026 following an extremely strong first quarter. Growth is now expected to be in the upper half of the range. The driver is "Industrial AI", which will scale massively in 2026.
2. operating margin (16.1%): This is the highest figure in the Group's history. Siemens is benefiting from the fact that the high-margin software business now accounts for almost 25% of total sales.
3rd profit explosion (+15.4%): EPS (earnings per share) is currently estimated at between €10.70 and €11.10 for 2026. This is a significant leap compared to 2025, due to efficiency gains from the company's own use of AI.
The current KCV (price to cash flow ratio) is 17.92 and therefore around 6 percentage points above the historical average of 12.
From this perspective, the share looks expensively valued.
The majority of analysts at Marketscreener recommend buying. Whereby the forecast price targets mean an average upside potential of 13
% on average.
But why is the Kgv and especially the KCV now above the historical average? For me, there is currently no overvaluation, because if you only look at the average, you are only looking in the rear-view mirror and not forward, but the future is traded on the stock market. And many analysts have raised their forecasts to €300:
1. the "SaaS trap" in cash flow (KCV)
Siemens is massively converting its software business (especially in Digital Industries) to subscriptions (SaaS).
- In the past: A customer bought a license for €1 million. The money was immediately in the till (low KCV).
- Today: The customer pays €200,000 per year over 5 years. Much less cash flows in the first year, although the contract is more valuable in the long term (high KCV).
- Conclusion: The cash flow currently looks "worse" because Siemens is swapping the one-off payments for predictable, more valuable long-term income. This artificially inflates the KCV.
2. margin expansion:
Siemens now earns significantly more per euro earned than in the past.
- Old Siemens: Lots of hardware, low-margin major projects, operating margins around 10%.
- New Siemens (2026): Focus on automation and industrial AI. Margins in the industrial business are now between 15.6 % and 18 %.
- Logic: A company that makes 50% more profit with the same turnover logically earns a higher multiple (P/E ratio).
3. the "Industrial AI" bonus
Siemens is no longer just a mechanical engineering company, but the market leader for the digital twin.
- In April 2026, Siemens will be valued on the stock market more like a tech company (similar to Schneider Electric or Microsoft) than a traditional industrial group.
- Tech companies have historically always had P/E ratios of 20+ because they grow faster and are more scalable.
However, there are of course also risks:
China lump: Siemens is extremely dependent on China. Geopolitical tensions or a "China-first" policy for software could immediately choke off the most important growth market.
- The valuation trap: Siemens is currently valued like a tech company (P/E ratio ~22). If the global economy slips into a recession, the market could once again value it like a "boring" industrial group (P/E ratio ~14) - this would correspond to a share price fall of around 35%.
- SaaS drought: The switch to subscriptions means less cash flow in the short term. If the economy weakens at the same time, the financial cushion from previous one-off payments will be lost.
- Big tech competition: Giants such as Microsoft and Amazon are pushing into Siemens' territory with their own industrial cloud solutions. Siemens must prove that its industry knowledge is more valuable than the pure computing power
of the IT giants.
Conclusion:
I am invested in Siemens myself because, for me, they have mastered the rare balancing act between "old industrial power" and "new software world". Despite the justified risks - such as dependence on China or the cyclical nature of the business - they are perfectly positioned today: They no longer sell just the hardware, but the digital brain of factories and power grids. This means they occupy the absolute future markets such as industrial AI and the digital twin, which no modern industrial company can ignore.
There is currently no direct undervaluation and anti-cyclical buying like Visa and Keyence is not possible here. However, I have taken advantage of the lower levels to add a little more and am convinced in the long term.
