🚨 [Financial Detective] SK Hynix, SanDisk, Kioxia! Exposing the 'Absolute Scale' and 'Dark Side of Profit Structure' through a Side-by-Side P/L Comparison of the 3 Companies
Hello, this is Kato-chan, your financial detective.
In the previous article, I thoroughly dissected SK Hynix's latest IR materials and revealed the truth about their astonishing earning power and financial fortress.
This time, I am taking a step further to attempt a 'new experiment'.
I will place the profit and loss statements (P/L) of the three major companies leading the semiconductor memory market—SK Hynix, SanDisk, and Kioxia—on the same table for a side-by-side comparative analysis.
In investment and financial analysis, looking at percentages (profit margins) is fundamental, but what is actually more important is the 'absolute amount (scale)' of the figures.
A '10% growth for a company with 10 million yen in profit' and a '10% growth for a company with 100 billion yen in profit' have completely different impacts on the market and market dominance.
This time, I will strip away the facade to reveal the decisive gaps between these three companies from both the 'absolute amount' and 'profit margin' perspectives!
🕵️♂️ 1. First, let's reverse-hack Kioxia's latest Q4 (fourth quarter)!
Before we dive into the comparison, there was one issue.
Kioxia's latest information is centered on their annual securities report (full-year data), which cannot be directly compared with the 'quarterly (3-month) data' of the other two companies.
Therefore, I reverse-calculated and determined Kioxia's Q4 (January-March period) standalone figures from the cumulative trend tables provided in their quarterly securities report information.
Q4 Revenue: Approx. 1.0285 trillion yen(Full year 2.3376 trillion yen - Q3 cumulative 1.3347 trillion yen)
Q4 Net Income: Approx. 407.7 billion yen(Full year 554.4 billion yen - Q3 cumulative 146.7 billion yen)
With this, we are ready to compare the three companies on the exact same timeline of the 'most recent quarter (approximately 3 months)'.
📊 2. Side-by-Side Comparison of the 3 Companies: The Shocking 'Scale (Absolute Amount)' Gap
For clarity, here is a table comparing the results of the most recent quarter, with each country's currency unified into Japanese yen (approximate rates: 1 KRW = 0.11 JPY, 1 USD = 150 JPY).
🌍 P/L Comparison Table for the Most Recent Quarter (Approx. 3 Months)
Side-by-Side Comparison Data for the 3 Companies (Most Recent Quarter, Converted to Japanese Yen)
*Calculated using approximate rates of 1 KRW = 0.11 JPY and 1 USD = 150 JPY
🥇 SK Hynix (Q2'26)
Revenue: Approx. 8.7 trillion yen
Net Income: Approx. 10.3 trillion yen
Gross Margin: 83.2% / Operating Margin: 76.3%
🥈 SanDisk (2026/7/3 Quarter)
Revenue: Approx. 1.34 trillion yen
Net Income: Approx. 1.03 trillion yen
Gross Margin: 84.6% / Operating Profit Margin: 78.5%
🥉 Kioxia (Q4 Estimate)
Revenue: Approx. 1.00 trillion yen
Net Income: Approx. 407.7 billion yen
Gross Margin: 43.3%* / Operating Profit Margin: 37.2%*
(*Kioxia's profit margins are based on full-year results)
🔍 3. The 'True Form' of Each Company as Told by Primary Data
From this comparison table, the decisive differences in the positions and profit structures of the three companies emerge clearly.
🥇 SK Hynix: The Absolute King of 'Scale (Amount)' and 'Monopoly Power (Margin)'
Looking at absolute amounts, SK Hynix's presence is now in a different dimension.
The revenue they generated in just three months (one quarter) (approx. 8.7 trillion yen) reaches about 3.7 times the revenue of Kioxia for 'one full year' (approx. 2.3 trillion yen).
In addition to the high profit margin (83% gross margin) from their HBM monopoly, non-operating income such as investment asset valuation gains exceeded 60 trillion won, resulting in a monstrous net income figure exceeding 10 trillion yen, which surpasses their revenue.
🥈 SanDisk: The 'Ultra-High Efficiency Monster' Stripped Down to the Limit
SanDisk's revenue scale (approx. 1.34 trillion yen) is on a similar scale to Kioxia (approx. 1.0 trillion yen), but what is noteworthy is its 'content (efficiency)'.
They boast a gross margin of 84.6% and an operating profit margin of 78.5%, profit margins that one would not expect from a hardware company. Operational costs such as R&D and SG&A expenses are kept to an absolute minimum, putting them more than 2.5 times ahead of Kioxia, which has a similar revenue scale, in terms of the 'amount' of net income.
🥉 Kioxia: A Traditional Player Putting Up a Fight but Being Swallowed by the Wave of 'Commoditization'
Kioxia's full-year revenue of 2.3 trillion yen and an operating profit margin of 37% are by no means bad figures when viewed as a typical manufacturing company.
However, while the top two companies are generating explosive free cash flow in a world of 'gross margins exceeding 80%,' Kioxia's gross margin (43.3%) clearly reflects its dependence on conventional NAND memory, which is subject to intense price competition.
🕵️♂️ Detective's Final Conclusion
The truth proven by this side-by-side comparison is that the multiplication of the 'difference in scale' and the 'difference in quality (profit margin)' is creating an insurmountable, massive capital gap.
SK Hynix accumulates vast amounts of cash through its 'overwhelming scale' and 'high profit margins,' and pours it all into next-generation investments (CapEx) on the scale of 40 to 50 trillion won annually.
SanDisk secures solid profit amounts exceeding its revenue scale through an 'ultra-high-efficiency cost structure'.
Kioxia is being left behind by its superiors in both revenue scale and profit margin, facing the limits of its financial strength in the next-generation investment race.
Even if news headlines are filled with words like 'AI special demand' and 'tailwinds for the entire industry,' if you line up and dissect the primary information known as the Profit and Loss (P/L) statement, it becomes immediately obvious who the true winners are and who is being forced into a tough battle.
Let's not be misled by superficial words and always strive to discern the 'structure' behind the numbers.
