[Stock Analysis] 4186 Tokyo Ohka Kogyo: The Shock of a 53% Explosion in Operating Profit in the 1Q Earnings Report! The "Absolute Mastermind" Controlling the Generative AI Market from Behind the Scenes
Hello, this is Pheue.
Thank you for always reading my articles.
Right now, the stock market in the era of the 60,000 yen Nikkei average is buzzing with two major mega-themes: "Generative AI" and "Space Defense." While global giants like NVIDIA and SpaceX are in the spotlight, professional institutional investors (such as Goldman Sachs) are keeping their eyes on the masterminds who exclusively supply them with "ammunition (materials)."
On May 11, 2026, the mastermind, Tokyo Ohka Kogyo (4186), announced its financial results for the first quarter (1Q) of the fiscal year ending December 2026, and it was truly astonishing. In this article, I will thoroughly dissect the latest figures and delve into why this stock is a "buy" even after exceeding the 10,000 yen mark.
1. 1Q 2026 Earnings: Otherworldly figures that continue to hit "all-time highs"
First, let's look at the figures that have just been released.
Net Sales: 67.077 billion yen (up 23.6% year-on-year)
Operating Profit: 15.074 billion yen (up 53.8% year-on-year)
Operating Profit Margin: Surged from 18.1% to 22.5%
This is an astonishing improvement in profit margins for a materials manufacturer, similar to the rock-solid stability of Shin-Etsu Chemical (4063), which I have analyzed previously. The progress rate against the first-half (January-June) plan has already reached 60.3%, marking a rocket start that makes an upward revision to the full-year earnings forecast (operating profit of 52.2 billion yen) almost certain.
2. Why is it so profitable? Photoresists that hold the "heart of generative AI"
The strength of Tokyo Ohka Kogyo lies in the fact that it boasts a top-tier global market share in photoresists (photosensitive materials) used in "lithography (exposure)," the most important process in semiconductor manufacturing.
① Exclusive demand for cutting-edge "EUV resists"
To make ultra-high-performance semiconductors for generative AI (such as the H100 or next-generation chips), "EUV (extreme ultraviolet) exposure technology," which can carve the world's finest circuits, is required. Tokyo Ohka has an overwhelming advantage in these EUV photoresists. The more orders that flood in for AI server semiconductors, the more the company's high-margin, cutting-edge resists are consumed, literally "like water."
② Explosion in "back-end (3D packaging)" materials
The current trend for AI semiconductors is "3D integration (such as CoWoS)," where chips are stacked on top of each other. Tokyo Ohka also holds a high market share in materials for high-density integration and high-purity chemicals used in this back-end process. The fact that they are fully absorbing the benefits of the AI bubble through both the "front-end" and "back-end" wheels is the true nature of this 53% increase in operating profit.
3. The "supply-demand buff" brought by national policy (SX Brand 2026) and the SpaceX IPO
In addition to perfect fundamentals (earnings), the company has two powerful "buying tailwinds (buffs)" blowing in the latter half of May.
Tailwind 1: Selection as a TSE "SX Brand 2026" Similar to Shin-Etsu Chemical, by being selected by the Tokyo Stock Exchange and the Ministry of Economy, Trade and Industry as a model for sustainability management, the company has gained a solid shield of supply and demand, as massive overseas ESG funds are now "obligated to buy (include in their portfolios)."
Tailwind 2: Disclosure of SpaceX's IPO application Ultra-miniaturization technology capable of withstanding harsh space environments is essential for manufacturing the cutting-edge chips required for the "Space AI Data Center" concept proposed by SpaceX. As the company that holds the materials for this, it is being viewed as a hidden defense and national policy stock in the space tech supply chain, prompting analysts to raise their target stock prices (to over 12,000 yen).
4. Summary
The stock price broke through 10,000 yen after the earnings announcement and is continuing to chase higher levels, at one point exceeding 11,000 yen. At first glance, it might look expensive in terms of P/E (Price-to-Earnings) ratio.
"A truly valuable global niche company should not be sold based on a high short-term P/E ratio. The sustainability of growth (moat) is what is essential." Analyst consensus forecasts (professional forecasts such as Minkabu) are also beginning to incorporate upward revisions toward a net profit of 39.3 billion yen (EPS scale of 326 yen), which significantly exceeds the company's own forecast.
It can be said that the credibility of including it in a portion of one's portfolio as the "true protagonist" of high-tech stocks driving the Nikkei Stock Average in the latter half of 2026 has increased even further.
