[Financial Anatomy #18] FANUC: The Japanese Company Monopolizing the 'Moving Limbs' of the AI Body
The king of robots that powers factories around the world is in Japan.
I'm Nui, the man who compares the market to a gym.
In the 18th installment of the 'Financial Anatomy' series, we look at FANUC.
'Limbs' appear once again
In the 13th installment, I dissected Tesla as the 'limbs of the AI body.' Robotaxis, the humanoid robot Optimus, and battery storage. It was positioned as an entity that outputs AI decisions into the real world.
However, Tesla's limbs are still limbs of a future that is yet to spread.
Robotaxi: Commercial service has only just begun
Optimus: In the mass production preparation stage
Not actually operating in many places around the world
On the other hand, FANUC, the subject of this installment, is different. They are limbs that have already been moving in factories around the world for decades.
Tesla (#13): A challenger attempting to create the 'new limbs' of the AI era
FANUC (this time): The king of 'mature limbs' already operating in factories worldwide
Even though they are both 'limbs,' they are on different layers. This time, FANUC represents a massive Japanese reality that has been driving the global manufacturing industry since before the AI era.
Where in the AI body anatomy chart?
FANUC is the king of the 'moving limbs' of the AI body.
In terms of the human body, it is a perfected system of muscles and nerves. These are mature limbs that have been moving since the moment they were born and have been used continuously for 20 or 30 years.
From the perspective of the AI era, FANUC's products are 'physical limbs that move accurately according to instructions given by AI.' Inside a factory, they continue to work 24 hours a day, with millimeter-level precision, without ever getting tired.
Toyota's car factories, the factories that make Apple's iPhones, and every manufacturing site around the world. FANUC's robots and CNC devices (the brains of machine tools) are what drive them.
In terms of strength training, FANUC is a personal trainer stationed in factories around the world. Moreover, they never get tired, never rest, and perform the prescribed sets perfectly with precise form 24 hours a day. They continue to deliver performance that a human trainer could never imitate for decades on end.
What kind of company is it?
FANUC has two main business pillars.
1. CNC Systems (The brains of machine tools)
CNC (Computer Numerical Control) is a system that controls machine tools. It acts as the 'brain' that uses computer control to accurately perform complex machining tasks such as cutting metal, drilling holes, and shaping materials.
FANUC holds approximately a 50% share of the global CNC market, meaning more than half of all machine tools are powered by FANUC's brains.
2. Industrial Robots
These are robots that automatically perform tasks within factories, such as transporting parts, welding, painting, and assembly.
FANUC holds approximately a 20% share of the global industrial robot market, making it a top-tier global player.
Its customers span all manufacturing industries, including automotive, electronics, semiconductors, machinery, food, and pharmaceuticals. FANUC is a company that does not rely on any specific industry, but rather functions as the 'limbs' for the entire manufacturing sector.
Two reasons for FANUC's strength
In the previous article on Keyence, I wrote that 'strength is born from the business model, not the industry.' FANUC's way of winning in its industry is also slightly different from other manufacturers.
Reason 1: CNC switching costs
Once a factory introduces FANUC's CNC systems, it becomes virtually impossible to switch to another company's equipment.
The reason is simple. Factory workers spend years mastering how to operate those CNC systems. Programs, machining conditions, troubleshooting, and maintenance are all optimized for FANUC equipment. Switching to another company's equipment would require retraining everyone, rewriting existing programs, and accepting the risk of 'what if something goes wrong.'
Many factories cannot take that risk. Therefore, once a factory adopts FANUC, FANUC is chosen again for subsequent capital investments.
This is the 'moat of switching costs' that I have mentioned many times throughout this series. Palantir, AWS, Advantest, Disco, Lasertec, Keyence, and FANUC—this 'moat' is a common feature among companies that are strong in the AI era.
Reason 2: An extraordinary operating profit margin of approximately 20%
The average operating profit margin for the manufacturing industry is around 5-10%. FANUC maintains an exceptionally high profitability of approximately 20%. For reference, Keyence is at 50%, but its business model itself is unique. As a standard manufacturer, FANUC achieves a profit margin two to three times the industry average.
This high profitability stems from the aforementioned switching costs and the structural advantage created by its top global market share in both CNC and robots.
Financial Physical Examination
Item | Evaluation
FY ending March 2026 Revenue | 857.8 billion yen (record high)
Operating Profit Margin | approx. 20% (extraordinary for a manufacturer)
CNC Global Market Share | approx. 50%
Industrial Robot Global Market Share | approx. 20%
Key Growth Drivers | Chinese EV sector, Indian IT sector
Maintaining an operating profit margin of 20% while sales are hitting record highs is proof of structural strength.
Nyu-i Judgment
💪 Anabolic state in progress.
Currently, FANUC's performance is being driven by robots for EVs in China and demand for IT in India. Amidst the global manufacturing trend toward AI, automation, and labor-saving, FANUC is one of the companies most directly benefiting from these tailwinds.
When considered in combination with the 'sensors and measuring instruments' mentioned in the previous Keyence installment, one can view the Japanese corporate pair of Keyence (the eyes of industry) + FANUC (the limbs of industry) as holding the core of global factory automation.
However, there is a point to note.
Dependence on the manufacturing industry's capital investment cycle. If the economy worsens and companies postpone the construction of new factories or capital investments, FANUC's orders will decrease. One should be aware that, unlike BtoC companies, these are not products that are 'guaranteed to sell'.
In terms of muscle training, FANUC has the same structural risk as a personal trainer who loses their job if the gym closes. Even if the trainer's own skills are top-tier, they cannot earn money if the gym itself does not exist. Similarly, even if FANUC's technology is top-tier, new orders will not be generated unless customers build or expand their factories.
However, in the long term, the trend of the manufacturing industry moving toward AI, automation, and labor-saving will certainly continue. Labor shortages, cost reduction, quality improvement, and environmental compliance—all directions are tailwinds for FANUC.
A word to investors
I do not recommend individual stocks. This article is an 'anatomical chart' for understanding the market.
Just one perspective based on this series.
There are two layers to the 'limbs' of the AI era.
Existing limbs (FANUC): Mature industrial robots already operating around the world
Future limbs (Tesla): New forms of AI-integrated robots that will become widespread from here on
These are fundamentally different in nature, even as investment decisions.
Investment in FANUC is an investment that evaluates the steady growth of already established technology and a customer base. It lacks flashiness, and returns accumulate over the long term.
Investment in Tesla is a bet on the potential success of a new business. If it hits, it could yield explosive returns; if it misses, it could result in significant losses.
Both are 'limbs,' but the stance required as an investor is different. Which growth story you believe in becomes the axis of your investment decision.
And, from the perspective of Japanese stock investment, FANUC and Keyence are companies worthy of long-term observation as the 'Japanese representative pair' for factory automation in the AI era. While they may lack flashiness, they possess a structure that allows them to keep winning.
