Good morning, dear getquin community.

Over the past few weeks, I’ve been taking a deep dive into the battery and energy storage industry—its entire value chain, the major players, and the hidden champions behind the scenes. Today, I’d like to share this knowledge with you @Tenbagger2024 and show how individual technologies are coming together to form a cohesive energy system. I look forward to hearing your perspectives on this.

It’s no coincidence that Warren Buffett $BRK.B (+0,26%) Berkshire Hathaway. He recognizes early on where real value is created and what role chemical processes play in the development of modern energy and storage systems. That is precisely where it will be determined how efficiently batteries and fuel cells will be produced, operated, and recycled in the future—and who will profit from this transformation in the long term.

Personally, I’m not yet as broadly positioned in this sector as I’d like to be. I’ve already invested in some segments, but the entire value chain still offers enormous potential—and that’s exactly what I wanted to better understand through this analysis, among other things.

I’ve deliberately avoided mentioning personal favorites @Multibagger to keep the analysis neutral. If you’re particularly interested in certain companies, topics, or questions, feel free to mention them here in the comments. I’m open to feedback, additions, and discussions, and if any key players are missing in a particular area, I’ll be happy to add them later. This post ended up being a bit longer because I wanted to present the topic comprehensively and clearly. If you’re primarily interested in the companies, the value chain, and the shovel manufacturers, you can skip ahead to points 13 through 16.

Perhaps Part 2 will cover fuel cells, if that’s what you’d like? I wish you all the best of luck with your investments and, of course, a wonderful Sunday.

2️⃣.Topic and Objective of the Article

The battery industry has long been more than just cell manufacturing or e-mobility. It is at the center of a global structural transformation that is redistributing energy, technology, and capital. The goal of this article is to understand the battery as a complete value chain—from raw material extraction through material technologies, production, and application to recycling and recovery.

I will show how genuine value is created along this chain, which industries benefit directly from it, and why the battery industry is becoming a central link in future energy systems. At the same time, the goal is to view the whole as a strategic model—a convergence of technology, economics, and sustainability that extends far beyond the mobility sector.

3️⃣.Basic Principle of the Battery

At its core, a battery is a chemical energy storage device that stores electrical energy in the form of chemical compounds and releases it again when needed. It consists of three main components: an anode, a cathode, and an electrolyte. During charging and discharging, positively charged ions move back and forth between these electrodes. This generates an electric current that can be used to power vehicles, supply machinery, or stabilize energy in grids.

The basic principle is reversible. This means that energy can not only be drawn from the battery but also fed back into it. This simple yet highly effective reaction makes batteries one of the central building blocks of modern energy systems. Thanks to advances in chemistry, materials technology, and manufacturing, performance is steadily increasing, while weight, charging time, and costs are continuously decreasing.

4️⃣.Applications

Today, batteries are far more than just a power source for electric cars. They are the backbone of modern energy systems and key to stabilizing renewable power grids. Their applications range from electric mobility to stationary energy storage to industrial and digital applications.

In the mobility sector, batteries enable the transition from internal combustion engines to electric drive technology and form the foundation of new vehicle platforms. In the energy sector, they serve as buffer storage for solar and wind power, balance out grid fluctuations, and ensure a reliable supply during peak times. In industry, they ensure supply reliability, efficiency, and emergency power solutions, while in data centers they are increasingly being used as emission-free backup systems.

In addition, new areas of application are emerging in aviation and maritime transport, in household and building systems, and in microgrids that supply remote regions or industrial parks with energy independently of the central grid. Batteries are thus a universal energy storage medium that connects sectors and lays the foundation for flexible, decentralized energy architectures.

5️⃣.Battery Life Cycle

A battery goes through a clearly defined life cycle that extends far beyond its actual use. It begins with the extraction and processing of raw materials, continues through cell and system manufacturing to the active use phase, and ends with the recovery and recycling of the materials.

During the production phase, active materials and cells are manufactured from raw materials such as lithium, nickel, manganese, cobalt, graphite, and copper. These cells are then assembled into modules and complete battery packs. During the usage phase, the batteries provide energy for years in vehicles, energy storage systems, or industrial facilities.

Once the end of their service life is reached, the second cycle begins. Cells that are still powerful enough are reused in so-called second-life applications, such as stationary energy storage systems. Finally, the recycling process takes place, during which valuable raw materials such as lithium, nickel, and cobalt are recovered and fed back into the production cycle.

This closed-loop material cycle is the crucial step toward a sustainable battery economy. It reduces dependence on primary raw materials, lowers environmental impact, and makes the entire value chain more resilient in the long term.

6️⃣.Future Trends

The battery industry is facing a period of massive technological and structural change. Progress is shifting from a focus on sheer capacity increases toward efficiency, sustainability, and material independence.

A key trend is the shift toward solid-state batteries, which—thanks to solid electrolytes—are safer, more compact, and more powerful than today’s lithium-ion systems. At the same time, silicon anodes are gaining importance, as they enable higher energy densities and shorter charging times. Sodium-ion batteries open up new possibilities for cost-effective storage solutions, particularly in applications where weight and energy density are less critical.

The digitization of batteries is also advancing. Smart battery management systems analyze the condition, temperature, and state of charge of each cell in real time. This not only improves safety but also extends service life and optimizes operation.

On an economic level, the industry is moving toward vertical integration: manufacturers are securing raw materials, energy suppliers are building their own storage facilities, and technology conglomerates are investing directly in manufacturing capacity. At the same time, political pressure is growing for a circular economy, recycling, and carbon neutrality.

The future of batteries thus lies in a combination of new materials, smart control systems, and closed-loop systems. Those who successfully integrate these three elements will play a decisive role in shaping the dynamics of the energy market in the coming years.

7️⃣.Raw Material Base and Development

The battery industry begins at the source of raw materials. Lithium, nickel, manganese, cobalt, copper, and graphite currently form the basis of nearly all high-performance cells. These metals determine the energy density, stability, and service life of every battery. At the same time, they are the most sensitive part of the value chain, as their extraction, processing, and supply determine costs, sustainability, and geopolitical dependencies.

A significant shift has taken place in recent years. Companies and governments are investing in new mining areas, recycling facilities, and alternative materials to ensure a secure supply. Lithium and nickel, in particular, remain key materials, while cobalt is increasingly being replaced. Graphite is undergoing a transformation toward synthetic and recycled forms, which are intended to reduce dependence on China.

The trend is clearly moving toward material efficiency and a circular economy. Instead of constantly opening new mines, closed-loop systems are emerging in which raw materials are reused multiple times. At the same time, alternative cell chemistries are coming to the fore, relying on abundantly available elements such as sodium, iron, or silicon.

This shift reduces costs, lowers environmental impacts, and increases the independence of entire economies. The raw material base of the battery industry is thus transforming from a linear supply chain into a global, circular material network that combines technology, recycling, and sustainability.

8️⃣.Value Chain

The battery industry follows a clear industrial logic that extends from the extraction of raw materials to the recycling of materials. Each stage in this chain creates its own value and is, at the same time, a prerequisite for the next.

1. Raw Material Extraction – Mining and extraction of lithium, nickel, manganese, cobalt, copper, and graphite from mines and salt lakes. This stage determines the cost structure and environmental footprint of the entire battery.

2. Refining and processing – Processing raw materials into battery chemicals, such as lithium hydroxide or nickel sulfate, which are used in cell production.

3. Materials technology and component manufacturing – Production of cathode, anode, and electrolyte materials, as well as separators, conductive foils, and binders.

4. Cell production – Assembling the materials into electrochemical cells through coating, stacking, and sealing. This step determines capacity, safety, and quality.

5. Module and pack manufacturing—Cells are assembled into modules and complete battery packs, including the battery management system and cooling.

6. System integration – Installation of battery packs in vehicles, energy storage systems, or industrial equipment. This is where the battery, software, and power electronics come together.

7. Use and operation – The battery’s operational phase spanning several years. Digital monitoring and predictive maintenance extend its service life and efficiency.

8. Recovery and Recycling – At the end of the life cycle, materials such as lithium, nickel, cobalt, and graphite are recycled and returned to the production cycle.

Together, these eight stages form the complete industrial cycle of the battery industry. Value is created at every stage, but it is greatest where technology, energy efficiency, and recycling intersect. This is the point at which a supply chain becomes a true value-creation system.

9️⃣.Value Creation Vectors in the Battery Industry

The battery industry is shaped not only by production processes but also by several overarching forces that act like vectors, cutting across all stages of the value chain. These vectors determine which companies remain at the forefront and where value is concentrated in the long term.

1. Technology Vector

Advances in cell chemistry, materials science, manufacturing, and software integration. Companies that scale up in these areas reduce costs and increase energy density, safety, and service life.

2. Digitalization Vector

Data management, condition analysis, cloud-based battery monitoring, and predictive maintenance. This level connects physical systems with AI and makes operations and recycling more predictable.

3. Sustainability Vector

Circular economy, carbon-neutral production, ESG standards, and material recycling. Companies that lead in this area secure long-term approvals and capital.

4. Finance and Investment Vector

Capital flows from government subsidies, private funds, and infrastructure programs that finance manufacturing capacity and research.

5. Infrastructure Vector

Construction of gigafactories, recycling centers, charging infrastructure, and energy storage facilities. This foundation is crucial for scaling up and ensuring supply security.

6. Geopolitical Vector

Location decisions, trade agreements, raw material dependencies, and security interests determine who has access to strategic materials and markets.

These vectors operate simultaneously and reinforce one another. The true dynamics of the battery industry emerge where technology, sustainability, and capital are intelligently intertwined. This is the axis where innovation, returns, and resilience converge.

🔟.Value Creation as a Cycle

The battery industry is increasingly evolving from a linear supply chain into a closed-loop system. Energy, materials, and data flow continuously between production, use, and recycling. The goal is to conserve resources, minimize losses, and increase value throughout the entire life cycle.

The cycle begins with raw material extraction and proceeds through material development, cell manufacturing, and integration, all the way to use in vehicles, energy storage systems, and industrial facilities. After the operational phase, materials are recovered and reused in new batteries. This physical cycle is complemented by a digital data cycle in which all relevant information about the condition, performance, and age of each cell is stored and analyzed.

This creates a system that optimizes itself. Data from operations flows back into research, design, and recycling, making new generations of batteries more efficient, safer, and more sustainable. This combination of physical and digital cycles is the key to genuine value creation in the Battery Industry 4.0.

1️⃣1️⃣.Macro and Micro Levels

The battery industry operates on two interconnected levels that drive and stabilize one another. At the macro level, global structures, political programs, and economic frameworks take shape. At the micro level, technological, chemical, and process-related developments come into play, making these larger trends possible in the first place.

The macro level encompasses everything that drives the industry as a whole: geopolitical interests, energy policy, subsidy programs, trade, infrastructure, and capital flows. This is where the course is set for where gigafactories are built, which countries secure access to raw materials, and how nations reduce their energy dependence.

The micro level describes the technical reality: cell chemistry, material innovation, manufacturing technology, software integration, and recycling processes. This is where actual progress takes place. Every new battery chemistry, every improvement in energy management, or every reduction in the use of rare metals alters the larger system in the background.

Both levels are intertwined. Political decisions and capital flows at the macro level enable technological developments at the micro level, while technological breakthroughs, in turn, trigger new markets, trade structures, and investment cycles. It is precisely at this intersection—where technology, politics, and the economy interact within a closed system—that the strategic potential of the battery industry emerges.

1️⃣2️⃣.The Significance of Battery Industry 4.0

Battery Industry 4.0 stands for the complete digitization and networking of all processes along the value chain. It combines production, energy, data, and sustainability into a single intelligent system that is controlled, monitored, and optimized in real time.

At its core is the integration of physical equipment with digital platforms. Every cell, every machine, and every process provides data that is analyzed using AI and analytics. This creates a self-learning system that detects errors early, ensures quality, and extends the service life of the batteries.

In manufacturing, automated lines, robotics, and machine learning maximize efficiency and precision. During operation, cloud services and IoT sensors enable continuous condition monitoring, which optimizes maintenance, safety, and performance. At the same time, environmental data is collected to make CO₂ footprints transparent and verifiable.

Battery Industry 4.0 is therefore not just a buzzword, but the transition to a fully integrated, data-driven energy industry. It lays the foundation for scalability, cost-effectiveness, and sustainability, and connects research, production, use, and recycling in a closed digital loop.

Visual Overview of the Battery Value Chain

To make the entire structure more tangible, I have divided the battery industry system into three levels:

1. Macro level: global value creation, energy policy, raw material and production networks.

2. Micro level: technological processes, material cycles, and innovation axes.

3. Overall Model: the integration of both levels into a closed-loop system that connects production, use, and recovery.

This diagram illustrates how linear supply chains evolve into a circular, digitally controlled energy system—the very DNA of the Battery Industry 4.0.

The hybrid energy flow illustrates how electricity, hydrogen, data, and raw materials reinforce one another in a circular, data-driven network. This is the foundation of Energy Infrastructure 4.0, which is dynamic, decentralized, and interconnected across sectors.

1️⃣6️⃣.Energy for humanoid robots: the next evolutionary stage of application

The next industrial revolution is no longer taking place solely in data centers or vehicles, but in the convergence of humans, machines, and energy. Humanoid robots symbolize this transition. These are systems that must think, act, and be self-sufficient. Their energy source is what makes them functional in the first place.

This is where battery technology, microgrid systems, and smart energy distribution intersect directly with artificial intelligence. Power density, longevity, and energy efficiency determine how autonomously these machines can operate. Whether in industry, healthcare, logistics, or everyday life, the stability of their energy supply is becoming a strategic factor for entire value chains. Next-generation batteries, solid-state systems, and mini fuel cells form the foundation for this. Companies that develop or supply these technologies are not only creating products but also building the infrastructure for a new form of intelligence that is energy-independent, networked, and scalable.

16.1 Technical Basis: What a Humanoid Really Needs in Terms of Energy

A humanoid robot is, at its core, a mobile energy system. It must walk, grasp, lift, balance, communicate, see, think, and remain safe while doing so. All of this requires a constant supply of energy.

Key requirements: high energy density with low weight, short-term power spikes, thermal stability, energy recovery, and long operating times without manual recharging. Currently, the energy requirements of humanoid robots range from 500 watts to 2 kilowatts, with energy storage capacities of 1 to 5 kilowatt-hours. A system is only considered suitable for industrial use if it can operate autonomously for several hours and recharge itself or swap modules.

16.2 Storage Status Today and in Five Years

Today:

Lithium-ion systems (NMC, NCA) dominate due to their high energy density.

LFP cells excel in safety and lifespan.

In five years:

Silicon anodes will increase energy density and charging speed.

Partially and fully solid-state batteries will improve safety and stability.

Combinations of batteries and fuel cells will emerge for continuous-load applications.

As a result, the robotics energy market is shifting toward modular, interchangeable high-performance cells with active thermal management and smart controls.

Medium term: Amprius, Enovix, Sila, QuantumScape, Solid Power—they increase energy density and operational reliability, the key criteria for autonomy.

System-wide: NVIDIA, AutoGrid, TWAICE – because the future lies not only in storage but also in the intelligent control of energy flow.

16.5 Practical Blueprint – Energy Stack of a Humanoid Robot

Energy Storage: Lightweight, high-energy battery module with active thermal management, based on NMC or silicon.

Drive: BLDC motors with harmonic or cycloidal gearboxes, integrated regenerative braking. Power electronics: Inverters and DC/DC converters from Infineon or STMicro, BMS from Texas Instruments.

Charging Infrastructure: Quick-swap packs, inductive intermediate charging with ADS-TEC or Wiferion.

Intelligence: Status diagnostics via TWAICE, energy coordination via AutoGrid, computational control via NVIDIA.

A stack like this not only makes humanoid robots operational but also economically viable. It’s no longer just about robotics—it’s about energy expertise. Whoever masters this stack controls not only the machine but also the business case behind it.

1️⃣7️⃣.Takeaway

The battery industry has long since evolved from a standalone solution into a multifaceted ecosystem in which materials, technologies, data, and energy flows are intertwined. Hybrid energy systems that combine batteries, fuel cells, and renewable sources are no longer a vision but a reality, evident in data centers, industrial parks, and transportation systems around the world. What matters most is no longer just how energy is generated or stored, but how it is intelligently controlled and integrated into existing grids. This is precisely where the real added value lies: in the ability to synchronize energy flows, data systems, and capital flows. Perhaps this is the point at which it will be decided in the future who will shape true energy autonomy—those who produce energy, or those who can control it precisely?

So dear friends...

Waiting for the maturity date of my 10y Treasury bond, interest payment will be taken along and, a little too early in the short term, but in the longer term shifted into 20+ Treasury at approx. 5 % p.a.. $IBTL (+0,09%) .

Furthermore, I finally got rid of my Global Clean Energy, albeit with a slight minus, but I see the cost pressure there immensely, and I also didn't like the weighting of the ETF "anymore".

With my savings rates, I'm trying to underperform Apple a little to get away from the almost 4 percent portfolio weighting. Apple is too annoying for me, at least in terms of the iPhone. Year after year, less and less innovation regarding smartphones, now under time pressure only a "half-finished" cell phone released in Germany.

On the other hand, I am quite happy with my portfolio.

I will continue to invest in real estate shares in the future, $DHL (+2,51%) I would like to push them to 1.5 %. I see an anti-cyclical opportunity here, the key figures seem to be okay. And the economy will also enjoy an upswing again at some point. Big player, albeit boring for some. But would like to upgrade it as a small individual share and hold it for the long term...dividend tastes good.

$PATH (-2,36%) and $ALFEN (-1,85%) will still think about a plan to sell, or one day one share will give way for the other.

We don't need to discuss Freyr and Halo, everyone starts at some point and unfortunately they are no longer tradable on L&S.

I am open to constructive criticism.

Have a nice evening and good luck 😅😅

--GER English version below

Dear congregation, I have a question for you: Leave it or Keep it?

I started investing toward the end of 2023 (aside from small amounts of crypto in 2021). I’ve bought various ETFs; the largest one is now $VWRL (+0,54%) and is also linked to my savings plans.

I intend to keep it as the strongest holding in my portfolio, along with and $IBGX (-0,18%) . In addition, $VWRL (+0,54%) , I also have a savings plan in a relatively well-performing active fund focused on India Equity Large Cap. I plan to keep these two or three funds as the main holdings in my portfolio. 

A while back, I shared the composition of my portfolio and asked for feedback. The issue was that I still own other small ETFs (e.g., $WFIN (-0,19%) , $WENS (+0,09%) etc.—along with others worth less than 1,500 euros). 

Now the question is: Should I keep them? If so, until when? I don’t intend to put any more money into them, since I want to diversify across 2 or, at most, 3 benchmark ETFs (as much as possible). That’s why I plan to restructure my portfolio a bit. 

Also, I’m not sure whether I should reduce my exposure to individual stocks. As you can see, I’m currently focusing on 6 stocks—5 of which are relatively growth-oriented, and 1 that is—if I may say so—more of a gamble. These are$NVDA (+1,35%)
$LLY (-1,06%)
$LMT (-0,52%)
$ALV (+1,42%)
$XOM (+0,06%)
$ALFEN (-1,85%) .

Am I overlooking something here? Or is the diversification good enough?

Time horizon: 10–15 years before I start selling anything.

Dear community, a question for you: Keep it or sell it?

I started investing (aside from small amounts of crypto in 2021) around the end of 2023. I’ve bought various ETFs; the largest one now is $VWRL (+0,54%) and I’ve also set up savings plans.

I plan to keep it as the strongest holding in my portfolio, along with $IUIT (+0,81%) and $IBGX (-0,18%) . Along with $VWRL (+0,54%) I also have a savings plan in a relatively well-performing active fund focused on large-cap Indian equities. I plan to keep these two or three as the main holdings in my portfolio.

I shared the portfolio composition a while ago, looking for feedback. The issue that came up was that I own other small holdings of ETFs (i.e. $WFIN (-0,19%) , $WENS (+0,09%) etc... with others amounting to less than 1,500 euros).

Now the question is: Should I keep them? If so, until when? I have no intention of putting more money into them, as I’d prefer to have 2 or at most 3 benchmark ETFs that are diversified (to the extent possible). Hence my plan to restructure things a bit.

Also, I’m unsure whether to reduce my exposure to individual stocks. Right now—as you can see—I’m focusing on 6 stocks: 5 of them are relatively growth-oriented, and 1 more—if I may say so—is a bit of a gamble. These are $NVDA (+1,35%)
$LLY (-1,06%)
$LMT (-0,52%)
$ALV (+1,42%)
$XOM (+0,06%)
$ALFEN (-1,85%) .

Am I missing something here? Or is the diversification good enough?

My time horizon is 10–15 years before I start selling anything.

Tip of the day!

Topic electromobility in Germany 🇩🇪

$ALFEN (-1,85%)

At Tuesday's meeting of the EU Parliament, it was agreed that motorists should be able to find a charging station at least every 60 kilometers within the main European transport axes. In addition, hydrogen refueling stations are to be built every 200 kilometers.

Since Compleo has encountered massive difficulties in Germany with regard to credits

I have been betting more and more on Alfen.

News fit and the consolidation seems to be completed.

In addition, they are already earning money and will certainly continue to grow solidly🤩.

Am already + 4 percent in plus, definitely continue to expand with further strength.

General data

The Dutch achieved revenue growth of 76 percent to 440 million euros with an EBITDA margin of 18 percent compared to 14.8 percent in 2021. For 2023, the company forecasts revenues of 540- 600 million euros.

Alfen N.V.

NL0012817175

Alfen N.V. is at the heart of the energy transition with its solutions. With transformers, energy storage, charging stations for electric cars and a wide range of other products and services, Alfen is the center and link in the power grid. With a wide range of products developed in-house and extensive experience as a system integrator, Alfen is working on the power grid of the future: reliable, sustainable and innovative [1]. Alfen is the market leader in the Netherlands in these areas. However, Alfen would like to continue to conquer the European market on this basis. Significant subsidiaries are located in the Netherlands, Finland and Belgium, with 61% of sales still generated directly from projects in the Netherlands, 38% in the EU and a marginal share outside the EU [2].

Revenue segments [2]:

Smart grid solutions (intelligent power grids): 52% of revenue.

Energy storage systems: 7% of sales

EV charging equipment (EV charging stations): 41% of sales

Key figures:

-KGV 2021: 89.1 [3]

-KGV 2022e: 61.3 [3]

-KGV 2023e: 43.0 [3]

-PEG 2022e (P/E/growth rate): 61.3/30%= 2.04 (rule of thumb: < 1 = very favorable)

-PEG 2023e: 43.0/30% = 1.43

-Goodwill: 0.13% of equity; 0.6% of 2021 earnings [2].

Goodwill contribution: https://app.getquin.com/activity/ymidZwhlTk

-Sales growth*: 2020 to 2021: 32% ; 2021 to 2022: 33.2%; 2022 to 2023: 37,88%

-EBIT growth*: 2020 to 2021 61%; 2021 to 2022: 33% ; 2022 to 2023: 41,8%

*10-year view not possible as data only available from 2015 (2015 sales €50 million). Due to industry and history, 10-year view not used. Annual report confirms the assumption of 30%.

Market Averages (EU) [5]:

-Aver. P/E Power: 16.99

-Aver. PEG Power: 1.71

-Aver. KGV Electronics (General): 30.73

-Aver. PEG Electronics (General): 0.95

Present Value Calculation = 89,46 € -->created by yourself

Share price as of 23.03.2022: € 84.32

Rubric - What would Buffet say (data from Annual Report 2021 [2]):

Criteria to be read in detail: https://app.getquin.com/activity/XcuRrJwmyP

Income Statement:

-Research and development: n/a (no data evident from Income Statement).

-Selling, general and administrative expenses: 21.48% of sales -->good!

-Gross margin: 35.97% -->good, tendency increasing! (Buffet's target: at least 40%)

-Net margin: 8.59% in 2021 (9.1% in 2022e) -->ok! (Buffet's target: >20%)

-Interest expense: 3.6% of operating profit-->very good! (Buffet's target: <15%)

Balance Sheet:

-Treasury shares: no buybacks planned!

-Debt < 4xEBIT: Verschuldung 3,7 --> ok!

Cash Flow Statement:

Capital Expenditures:

2021: 54% of net profit (Buffet's target: <50%)

2020: 80,6% des Reingewinns

2019: 118,9 % des Reingewinns

-->development ok, considering the industry, which has high investment needs. To this end, the cash position will be continuously expanded (2019: 134k; 2020: 52m; 2021: 47.2m).

Key Note:

For asset-intensive and project-driven companies, I like to look at the development of inventories, in conjunction with sales. It is good to see here that inventories are continuously growing in line with sales. This is also a sign that the order situation is good and that there are no particularly "slow-moving items" that will have to be written off at some point to reduce profits: The inventory turnover rate (sales/average inventory level) also indicates how often the company "turns over" its inventories within a year, i.e. how often the inventory is "emptied" in a year (even if this happens in practice on a rolling basis and the inventory is never completely empty - hopefully).

Inventory turnover rate 2021: 8.11 (249/30.7)

Inventory turnover 2020: 1.16 (19.9/17.15)

Inventory turnover rate 2019: 1.2 (14.4/ 11.95)

Sales 2021: 249 million

Sales 2020: 189 million

Sales 2019: 143 million

Inventories 2021: 41.5 million

Inventories 2020: 19.9 million

Inventories 2019: 14.4 million

Inventories 2018: 9.5 Mio

Burggraben:

Alfen is in a growing market with many opportunities. However, I do not see a concrete competitive advantage. However, with their charging stations and energy storage systems, the order books will certainly not be empty. Alfen wants to unify its solutions and systems to serve the entire supply chain (smart grids, electricity storage, charging stations). This strategy definitely makes them competitive. To that end, I definitely like the key figures.

Peer Group/Competition:

Siemens Energy

-KGV: negative (2021), 2022e: 154; 2023e: 21.4

-PEG 2022: 154/30 = 5.13; 2023: 0.71

Growth assumption analogous to Alfen. However, existing data could indicate more like 20-30%.

Blink Charging

Profit zone hardly predictable. Growth given, however, still long way to go! Company is still at the beginning. Sales at just under 21 million in 2021!

https://blinkcharging.com/

Wallbox NV

No profit yet. Profit probably not until 2024/25, but very difficult to forecast. Growth, however, given, analogous to Alfen.

https://wallbox.com/de_de/ueber-uns/vi-er-wallbox

Non-public competition:

Nexgrid

Swissgrid

VTTI

Company classification according to Peter Lynch [4]:

Fast Grower (growth rate &gt;20% )

Conclusion:

I find Alfen extremely exciting. The market allows for a lot of imagination. They have been in a major sideways chart move since January 2021. My hope is that they will serve this again and return in the €60-70 range. Of course, you can not be sure. Possibly there is also a good resistance at about 80€. The e-mobility company would do very well in my portfolio, since I do not really serve this sector yet. One thing to keep in mind, however, is the competition. In addition to the aforementioned peer group, I also see classic car manufacturers, which of course also include Tesla or VW, as competitors to a certain extent, even if not in all segments of Alfen.
