GO（581A）Post IPO Note Not a Taxi IPO The market bought a mobility OS Initial price 2,910 yen Market cap About 226bn yen Debate PER around 35x Can it bundle dispatch, payments, SaaS, ads, and GX?

First, let's clarify the meaning of the initial value

GO's first day of listing went pretty well just looking at the numbers.

Initial prices for large-scale IPOs are difficult to increase. This is because the amount absorbed is large and the number of shares sold is large.

Please note that this IPO is not a public offering to raise new funds, but rather a secondary offering. Rather than a listing that brings in new funds to the company for growth investment, it is more likely to be an exit for some existing shareholders and price discovery in the market.

Even so, GO exceeded the public price by more than 20%. This probably means that the market has decided that this is not a bad thing for a large-scale growth IPO.

However, I would like to take a calmer look here.

The initial price of 2,910 yen is a PER of approximately 35 times based on the company's expected net income of 6.4 billion yen for the fiscal year ending May 2026. Although this is not an extremely abnormal level in Japan's growth market, it is high if you only look at the maturity of the taxi market.

In other words, the market does not see GO as a company that increases the number of taxi rides.

Rather, they see it as a digital billing layer on top of the taxi industry.

The market doesn't see GO as a taxi company

GO's disclosed business content is "mobility-related business such as providing ride-hailing systems."

This is important.

GO is a taxi transportation company with a large fleet of vehicles and crew, and is not a company that makes money from fare differentials. It is a company that connects existing taxi companies and users and overlays payment, corporate management, advertising, terminals, recruitment, and GX.

I think investors highly valued this asset-light feature.

Investor evaluation axisFreight, occupancy rate, personnel costsMAU, number of uses, take rate, peripheral revenue
RisksLabor shortages, fuel costs, vehicle investmentRegulations, supply shortages, competition, system reliability

GO has been downloaded over 35 million times in total, and is available in 47 prefectures across the country, with approximately 85,000 taxis available. The number of GO BUSINESS contracts is said to be over 15,000.

What this number means is not just the number of app downloads.

This means that it has an entrance that brings together individuals who want to get around, corporations that use taxis, businesses that operate vehicles, advertisers, and future EV charging and self-driving players in the same place.

This is the reason why the market allowed the market capitalization to exceed 200 billion yen.

What's different from Uber?

When we talk about GO, we inevitably end up comparing it to Uber.

However, in the Japanese market, it can be a mistake to make this comparison sloppily.

Globally, Uber is a company that has expanded ride sharing to include regular drivers. On the other hand, in Japan, there are restrictions in the Road Transport Law and the taxi system, and Uber has had no choice but to develop its business mainly through partnerships with taxi companies.

GO was built with this in mind from the beginning.

StrengthsCompatible with 47 prefectures nationwide, corporate use, payments, advertising, and terminalsGlobal brand, overseas operation know-how, app experience
WeaknessesDependence on the existing taxi industryJapan has thick institutional and local network barriers

In Japan, it was more suited to the system to take over the operation management and dispatch efficiency of taxi companies than to try to destroy the taxi industry head on.

GO went to pick it up.

This choice was correct in the short term. That's why we were able to create one of the largest ride-hailing networks in the country.

However, in the medium to long term, the same structure also poses risks. If the role of existing taxi companies themselves is shaken due to the complete lifting of the ride-sharing ban and the spread of robotaxis, the question will be asked whether GO is a `company that is strong in tandem with the existing industry'' or `a company that is tied to the existing industry.''

This will be the biggest issue after listing.

There are four growth engines

The reason GO has been evaluated by the market as similar to a tech company is that it does not have a single source of revenue.

If it's just a ride-hailing app, the room for growth is pretty much tied to the number of times taxis are used. But GO picks up the revenue before and after the taxi ride.

GO revenue layers
├─ 1. App dispatch and payments: arrangement fees, system usage fees, payment-related revenue
├─ 2. Corporate usage: GO BUSINESS, billing and expense management digitization
├─ 3. Taxi DX: terminals, dashcams, hiring support, operational services
└─ 4. Advertising, GX, and next-generation domains: TOKYO PRIME, EV charging, autonomous driving, logistics DX

1. App dispatch/payment

The focus is still on dispatch.

Users use the app to hail a taxi and pay for it. Arrangement fees, system usage fees, and payment-related revenues are generated from this.

In the forecast for the fiscal year ending May 2026, GO business sales are expected to increase 35% year on year to 36.9 billion yen. In addition to an increase in users, the company expects average sales per vehicle to rise due to improved app arrangement fees.

It's strong here, but it also has its limits.

Even if the number of users increases, if there are no taxis in the city, dispatch will not be possible. We need to see not only the demand for apps, but also whether the supply side will grow in number of vehicles, crew, and regional density.

2. GO BUSINESS

GO BUSINESS for corporations becomes quite important in evaluation after listing.

Using a taxi for a company involves many tedious tasks, such as receipts, paper taxi tickets, and departmental expense settlements. GO BUSINESS centrally manages this on the cloud.

It's not flashy compared to personal apps. However, once corporate users enter the business flow, it is difficult to escape.

It's this kind of return that the market likes.

If the stock nature of corporate transportation expense management comes into play, rather than just the number of one-off rides, GO's evaluation will move from a `mobility app'' to a `business infrastructure.''

3. Taxi DX

GO is also expanding beyond the app.

In-vehicle payments, drive recorders, recruitment support, and business support for taxi companies. All of them are unassuming, but they are similar to the management infrastructure of a taxi company.

In particular, the driver shortage is a constraint for the entire industry. Recruitment support like GO Jobs is also important in terms of protecting the user experience of the app.

What we should look at here is the degree of stickiness with taxi companies rather than the scale of sales.

If taxi companies use GO not just as a customer transfer app, but as a partner that includes everything from business management, recruitment, payments, advertising, and EV support, there will be less room for competitors to enter.

4. Advertising/GX/Next generation field

Don't miss the TOKYO PRIME rear seat signage.

On GO's service page, TOKYO PRIME is said to be Japan's largest taxi media with signage installed in a total of 71,000 taxis in 35 prefectures nationwide. Taxi advertising tends to be evaluated as a medium that can easily reach business and high-income groups in urban areas.

Furthermore, EV charging, energy management, autonomous driving, and logistics DX are also strong themes.

Waymo cannot be excluded as a specific name here. In December 2024, GO announced a strategic partnership with Waymo, a subsidiary of Alphabet in the US, and Nihon Kotsu to test Waymo's self-driving technology "Waymo Driver" in Tokyo. The fact that autonomous driving is not just a future theme, but also has an entry point for demonstration in Tokyo, is likely to be a source of hope for the market.

However, it is dangerous to buy this place based on just a dream.

GX and autonomous driving involve capital investment, coordination with local governments and business operators, vehicle costs, insurance, accident response, remote monitoring, and legal systems. The time horizon for contributing to profits is long.

What investors should check immediately after going public is not the story of ``we will create next-generation mobility,'' but rather how well the company is working on which KPIs.

The biggest risk is “dependence on the taxi industry” itself

GO's strength lies in its deep relationships with domestic taxi companies.

But in investing, strength and risk often come from the same place.

In the case of GO, it depends on the taxi industry.

Ride sharing and autonomous driving advance
        ↓
1. Operations remain led by existing taxi companies
   → GO can become shared infrastructure

2. Regulation loosens sharply and private cars, overseas players, or robotaxis enter directly
   → Dependence on the existing taxi network becomes a heavier risk

If Japanese-style ride sharing continues to expand under the operation management of taxi operators, it will be a tailwind for GO. There are only a limited number of players who can connect with existing taxi companies and handle operations management, dispatch, and payment.

Conversely, if regulations change significantly and private drivers, foreign platforms, and self-driving vehicles enter the market more directly, the conditions for competition will change.

Will GO continue to be an ally of existing taxi companies? Will new supply sides be brought in as well? Or can it become a neutral infrastructure that connects both?

There is no answer here yet.

The initial price of 2,910 yen is the price at which the market viewed this difficult problem favorably. I think the price is based on expectations rather than certainty.

KPIs to watch after listing

If you want to follow GO after it goes public, looking only at the stock price is not enough.

The KPIs to check are pretty clear.

KPIView
MAUAre apps growing as part of our daily life infrastructure?
Number of usesLook at actual movement demand, not downloads
Sales per number of usesView monetization of arrangement fees, payments, corporations, and advertising
Number of available taxisIs supply keeping up with increasing demand
Number of GO BUSINESS contractsView the stock nature of corporate transportation expense management
Advertising/GX sales compositionAre profit sources other than ride dispatch growing?
Operating profit marginView operating leverage through platformization

Of particular importance is the combination of sales growth rate and operating profit margin.

Even if the number of rides increases, if advertising costs and revenue share are heavy, profits will be difficult to grow. On the other hand, if the operating profit margin increases even if sales growth slows down a little, the market will likely evaluate the company highly.

After listing, the initial focus will be on the performance for the fiscal year ending May 2026 and the guidance for the fiscal year ending May 2027.

If the company achieves operating income of 7 billion yen as planned and can see a path toward 10 billion yen in the next fiscal year, the initial price of 2,910 yen will be ``a high but understandable price.''

On the other hand, if the number of uses does not increase due to supply constraints, the contribution of advertising and GX to profits is not visible, and foreign investors sell, the market capitalization of over 200 billion yen will be weighed down.

Conclusion: A large-scale experiment in real industrial DX has begun

GO's listing is not the IPO of a company that has made it possible to call taxis using smartphones.

How will a company that has re-wrapped one of Japan's most heavily regulated and conservative real industries with apps, payments, corporate SaaS, advertising, data, and GX be evaluated in the stock market? This is an experiment.

The initial price of 2,910 yen and the market capitalization of approximately 226 billion yen are quite strong evaluations from the market.

However, at the same time, the homework is also heavy.

GO is strong because it has coexisted with taxi companies. However, in the era of ride-sharing and self-driving, the question is how to reshape that symbiotic relationship.

From this point on, what we should be looking at is not the topicality.

Number of dispatches, MAU, revenue per ride, corporate contracts, operating profit margin, and response to system changes. If this number increases, GO will become closer to a Japanese-style mobility OS.

If it doesn't grow, the initial heat will cool down.

GO may be a good company. However, the stock price after listing will be determined by whether the company can become a "profitable infrastructure" rather than a "useful app."

Investment decision memo

This article summarizes GO (581A)'s business structure and IPO initial price, and does not recommend buying or selling specific stocks. Immediately after an IPO, stock prices fluctuate significantly not only based on performance, but also on the supply and demand of public stocks, the release of lock-ups, buying and selling by foreign investors, and overall growth market conditions.
