On July 30, Samsung Electronics' Q2 2026 earnings report stunned the semiconductor industry. On a consolidated basis, quarterly operating profit surged 1813.8% year-on-year to 89.49 trillion won (about 419.9 billion yuan), exceeding the combined profit of the past three years; revenue hit a record 171.5 trillion won, up 130% year-on-year, both setting new quarterly highs. The earnings explosion at the world's largest memory chip maker pushed the AI-driven semiconductor upcycle to new heights, putting Vietnam, a global back-end manufacturing hub, back in the investment spotlight.
Earnings 'explosion': semiconductor division profit surges 250-fold
By segment, Samsung's growth was driven almost entirely by its semiconductor division. The division posted Q2 operating profit of 89.2 trillion won, up more than 250 times year-on-year, accounting for the vast majority of total profit; net profit of 71.27 trillion won also set a quarterly record. In contrast, consumer electronics and mobile businesses posted losses, creating a stark 'ice and fire' split.
The direct driver of the profit surge was the historic memory chip rally. Driven by AI data center buildouts, DRAM contract prices rose for months, climbing another 14.3% month-on-month in July to an all-time high; NAND benchmark prices broke above the $30 mark. Top manufacturers shifted capacity to high-value AI memory products like HBM, severely constraining supply of traditional memory for smartphones, PCs, and autos, sending prices higher.
Data from TrendForce and other institutions shows the duration and magnitude of this memory upcycle have exceeded early-year expectations, with '2027 as the tightest memory year' becoming industry consensus. Multiple memory makers have sold out 2027 capacity in advance, with buyers even required to place deposits to secure supply—a clear sign of robust demand. The memory chip's strong cyclicality is taking on new growth dimensions in the AI era.
$1.5 billion bet on Thai Nguyen: Samsung's first chip testing plant in Vietnam
Samsung's explosive earnings are rippling through Vietnam's supply chain. Approved in March and breaking ground in April, Samsung's first chip testing plant in Vietnam is the latest testament to this ripple effect. Located in the Thai Nguyen Province industrial park, about 60 kilometers north of Hanoi, the plant represents an investment of roughly $1.5 billion and is slated to begin production in November 2027, with annual testing capacity planned at 153.3 billion Gb DRAM and 255.6 billion Gb NAND, targeting the currently supply-constrained mature-node memory chips.
Notably, Samsung plans to reinvest project profits; if a second phase proceeds, cumulative investment could reach up to $4 billion, potentially creating around 3,750 jobs. In Thai Nguyen, the testing plant sits adjacent to Samsung's existing smartphone and tablet production base, creating a synergistic 'device assembly + chip packaging and testing' layout that further cements Vietnam's position in the global electronics manufacturing landscape.
In fact, Samsung is already Vietnam's largest foreign investor, with cumulative pledged investment exceeding $23 billion. This latest addition to chip testing marks Vietnam's role in Samsung's global supply chain upgrading from 'manufacturing and assembly' to 'semiconductor back-end,' with clear spillover benefits for Vietnam's electronics manufacturing sector.
From packaging and testing hub to 'Make in Vietnam': policy tailwinds intensify
Samsung is not alone. Leveraging labor costs, geographic location, and free trade agreements, Vietnam has long hosted packaging and testing facilities from multinationals including Intel, Amkor, and Hana Micron, making it a key global back-end semiconductor base. In 2025, Vietnam's semiconductor industry revenue exceeded $21 billion, attracting over 240 FDI projects with investment surpassing $14 billion, ranking among the fastest-growing in the Asia-Pacific region.
On the policy front, Vietnam is supporting the chip industry with unprecedented vigor. On August 4, Deputy Prime Minister Ho Quoc Dung signed Decision No. 1481, officially including semiconductor chip development, design, trial production, measurement, testing, and evaluation services in the public service list supported by state funding, covering 22 services across six areas including digital transformation, technological innovation, and intellectual property—providing tangible financial backing for the domestic semiconductor chain. Earlier, Vietnam established its first national chip trial production support center, committing to fully subsidize tape-out costs for universities and enterprises in 2026-2027, shifting to a co-funding model in 2028-2030, directly addressing the pain point of local chip design firms with no fab to tape out.
Under the plan, Vietnam aims to have at least 100 chip design companies, one wafer fab, and about 10 packaging and testing facilities by 2030, with annual semiconductor revenue exceeding $25 billion. Provinces like Thai Nguyen have also issued resolutions offering cost subsidies of up to 50% of investment for chip design projects. From central to local levels, policy momentum is accelerating.
Investment logic: AI boom spills over, Vietnam supply chain revalued
From an investment perspective, Samsung's earnings and Vietnam's supply chain expansion reveal a clear logic chain: AI computing demand explosion → memory chip supply-demand imbalance → record prices and profits → capacity and back-end testing spillover → Vietnam and other back-end manufacturing bases absorbing new investment. For investors, the answer to 'why invest in chips' is being repeatedly validated by the world's largest chip company with real money. At this stage, the core investment highlights can be summarized as follows:
- Clear supply-demand gap: AI data center buildouts are driving demand for HBM and high-bandwidth memory, crowding out traditional memory capacity, making the shortage-driven price rally hard to reverse in the near term;
- Huge profit elasticity: Memory makers' quarterly profits have soared tens of times, significantly enhancing earnings certainty across the upstream and packaging/testing segments;
- Regional shift dividend: As a core beneficiary of the 'China+1' supply chain shift, combined with local policy support, Vietnam is evolving from an assembly hub into a semiconductor ecosystem with design, packaging/testing, and trial production capabilities;
- Long-term growth profile: Semiconductors combine cyclicality with growth, and AI-driven structural demand is injecting lasting momentum that can outlast cycles.
Of course, investing in semiconductors still requires caution regarding cyclical volatility. Historical experience shows that after sharp rallies, the memory industry often faces price corrections as capacity comes online; Vietnam's local chip manufacturing still faces bottlenecks such as high tape-out costs, a shortage of skilled talent, and reliance on imported EDA tools. But at the current stage, AI-driven structural demand combined with Vietnam's policy tailwinds keeps the long-term investment value of the chip sector prominent.
From Samsung's 18-fold quarterly profit surge to the rise of Vietnam's first chip testing plant, the dividends of the AI chip boom are rippling along the supply chain. For investors focused on semiconductor opportunities, Vietnam—this rising chip back-end hub—deserves sustained attention and in-depth positioning.
