The narrative surrounding Coupang (NYSE: CPNG) shifted dramatically on Friday, December 26, 2025, providing a textbook example of how quickly sentiment can pivot in the high-stakes world of global e-commerce. Shares of the South Korean giant surged by as much as 11% during intraday trading, marking its most significant one-day advance since early May. This vertical move followed an official update from the company regarding a massive data security investigation that had previously loomed over the stock like a permanent cloud. By identifying a former employee as the sole perpetrator and demonstrating ironclad cooperation with government authorities, Coupang transformed a “systemic risk” narrative into a “contained governance” success story.
But for the sophisticated investor, the 11% rally is not the end of the story—it is merely a reset. When one peels back the layers of recent headline volatility, what remains is a fundamentally dominant enterprise trading at a significant discount to its intrinsic value. As Coupang aggressive expands its “Rocket Delivery” infrastructure into Taiwan and scales its high-margin advertising and streaming businesses, the current valuation looks increasingly like a rare entry point for a “compounding machine” in the making.
The Anatomy of the Rally: Bounding the Cybersecurity Risk
To understand why the market reacted so violently to the upside on Friday, one must first understand the depth of the preceding fear. Earlier in December 2025, Coupang was rocked by reports of a data breach involving approximately 33.7 million customers—a figure that represents nearly two-thirds of the South Korean population. The fallout was immediate: a 19% drop in share price over the first three weeks of the month, a CEO resignation at the South Korean subsidiary, and a flurry of regulatory inquiries.
The 11% surge on Friday occurred because Coupang successfully “bounded” the liability. The company confirmed that the breach was an internal leak by a rogue former employee rather than a sophisticated external state-sponsored hack. Critically, Coupang revealed that while 33.7 million records were accessed, the perpetrator only actually saved data from roughly 3,000 accounts. Furthermore, the company provided the “golden assurance” that institutional investors were waiting for: sensitive financial data, including credit card numbers, login credentials, and personal customs clearance codes, remained untouched.
By framing the incident as a contained breach by a single bad actor with limited data retention, Coupang removed the catastrophic “worst-case scenario” of massive financial theft and systemic security failure. This clarity allowed the market to stop obsessing over legal “what-ifs” and return its focus to the company’s staggering operational performance.
Fundamental Dominance: The Numbers Behind the Rocket
Beyond the cybersecurity noise, Coupang’s third-quarter 2025 financial results, released in November, painted a picture of a company firing on all cylinders. Coupang reported net revenues of $9.3 billion, an 18% year-over-year increase on a reported basis and 20% on a constant currency (FX-neutral) basis. To put this in perspective, the broader South Korean e-commerce market grew by less than 2% during the same period. Coupang isn’t just growing; it is essentially the only player effectively capturing incremental growth in its home market.
The “Product Commerce” segment, which houses the core retail and Rocket Delivery operations, generated $8.0 billion in revenue, up 16% YoY. More importantly, this segment is becoming a cash-generating engine. Adjusted EBITDA for Product Commerce surged to $705 million, with margins expanding significantly to 8.8%. This margin expansion is a direct result of Coupang’s massive investment in automation and AI-driven supply chain optimization—investments that competitors like Naver or G-Market cannot easily replicate without billions in new capital.
Key fundamental drivers currently supporting an undervalued thesis include:
- Customer Stickiness: Active customers grew by 10% YoY to 24.7 million. More crucially, the net revenue per active customer rose to $323, a 5% increase. This proves that once customers enter the “Rocket” ecosystem, they spend more and use more services over time.
- Operating Leverage: Gross profit increased 20% YoY to $2.7 billion. As Coupang scales, its fixed costs—the massive network of over 100 fulfillment centers—are being spread over a much larger revenue base, leading to a “J-curve” in profitability.
- Cash Flow Strength: Trailing twelve-month operating cash flow reached $2.4 billion, with free cash flow (FCF) climbing to $1.3 billion. This gives Coupang the “war chest” needed to fund international expansion without diluting shareholders.
The Taiwan Thesis: Exporting the South Korean Miracle
While South Korea provides the stable “cash cow,” Taiwan is the new “growth engine.” Management has noted that the Taiwan expansion is progressing faster than the early days of South Korea. In Q3 2025, Coupang’s “Developing Offerings” segment, which includes Taiwan and Coupang Play, saw revenue jump 32% to $1.3 billion.
Taiwan is a particularly attractive market because of its high population density and advanced digital infrastructure, mirroring the conditions that allowed Coupang to succeed in South Korea. By exporting its logistical “secret sauce”—nighttime ordering for next-day 7:00 AM delivery—Coupang is disrupting the fragmented Taiwanese e-commerce market. Analysts estimate that if Coupang can capture even 15% of the Taiwanese market by 2027, it would add billions to its top line with higher margins than its domestic business due to lower land and labor costs.
Valuation Analysis: Is Coupang a Bargain?
Currently trading at a market capitalization of approximately $44 billion, Coupang is being valued at roughly 1.3x trailing revenue. For a company growing its top line at 20% and its EBITDA at double that rate, this is an anomaly. Global peers in the e-commerce space with similar growth profiles often trade at 2x to 3x revenue multiples.
The primary reason for this “valuation gap” has been the perceived regulatory and security risk in South Korea. However, Friday’s rally suggests that the market is finally realizing these risks are transitory, while the logistical moat is permanent. A Discounted Cash Flow (DCF) model based on conservative 2026 projections suggests an intrinsic value of approximately $36 per share. With the stock currently hovering in the $24 to $25 range, investors are looking at a potential 40% to 50% upside as the “breach discount” continues to evaporate.
Furthermore, Coupang has begun to return capital to shareholders, repurchasing $81 million worth of shares in Q3 alone. This signaling from management suggests that even they believe the stock is undervalued at current prices.
The Risks: Competition and the Regulatory Sword
No analysis is complete without addressing the bear case. While Coupang is dominant, it is not without challengers. The entry of Chinese cross-border giants like AliExpress and Temu into South Korea has pressured pricing in low-margin categories. Additionally, Naver remains a formidable rival in the digital search and payment space.
Regulatorily, the South Korean government remains vigilant. The Fair Trade Commission (FTC) has previously scrutinized Coupang’s search algorithms and its treatment of third-party sellers. Any future fines or restrictive legislation could temper growth. However, Coupang’s massive role as an employer (the third-largest in South Korea) and its critical infrastructure status provide a degree of political insulation.
Conclusion: A High-Conviction “Buy” Recommendation
The 11% intraday surge on Friday was more than just a relief rally; it was a market re-awakening. By resolving the uncertainty surrounding the data breach, Coupang has cleared the way for investors to re-examine a business that is growing 10x faster than its market average.
Coupang is no longer a speculative startup; it is a mature logistical titan with a proven ability to generate billions in free cash flow. Its “Developing Offerings” are diversifying the revenue stream, and its core business is benefiting from massive operating leverage. For long-term investors, the recent volatility has created a “gift” of an entry point. The “Rocket” is back on its trajectory, and the next stop is likely a return to its 52-week highs above $31, followed by a sustained march toward the $40 mark in 2026.
Final Verdict: Undervalued. Recommendation: BUY.
