Samsung Electronics reported revenue of 171.5 trillion won ($119 billion) in the second quarter of 2026, up 28% from a year earlier and the highest quarterly total in the company's history. Operating profit reached 89.5 trillion won ($62.2 billion), also a record, with earnings per share rising 52% (Samsung Newsroom, Engadget).

But those headline numbers hide a sharp split inside the company.

The division that makes Samsung's memory chips and other semiconductor products, called the DS (Device Solutions) Division, saw sales jump 56% compared to the previous quarter. The Memory Business alone set all-time highs for both revenue and profit, driven by the surge in demand for AI chips that has lifted the entire semiconductor industry. Samsung's Networks Business also improved in Q2 2026 (Samsung Newsroom).

Meanwhile, the division that makes Samsung's phones, TVs, and home appliances, called the DX Division, posted its first-ever quarterly loss of 800 billion won ($544 million) (Engadget). Reuters confirmed that the mobile division swung to a loss for the first time (Reuters).

The loss came from the mobile side of the business. Samsung said phone sales actually grew compared to a year earlier, helped by the Galaxy S26 series and A series phones. But profit fell because the cost of the components inside those phones, especially memory chips, went up sharply (Engadget, Samsung Newsroom). The irony is straightforward: the same memory-chip shortage that delivered record profits to Samsung's chip division raised the cost of building Samsung's own phones. Cheaper phones were hit the hardest, because their profit margins were already thin (Engadget).

Samsung had warned this might happen. In April 2026, the company signaled the possibility of a first-ever mobile division loss, as reported by 9to5Google (Engadget). At the time, Samsung pointed to rising RAM prices as the main reason.

The shift from the prior quarter is dramatic. In Q1 2026, Samsung's mobile business saw sales and profit increase, with total company revenue at KRW 133.9 trillion and operating profit of KRW 57.2 trillion (Samsung Newsroom). A year earlier, in Q2 2025, the mobile and networks businesses together had posted KRW 29.2 trillion in revenue, though smartphone performance had already been declining (Samsung Newsroom).

Samsung's preliminary profit estimate for Q2 2026, released July 6, was 89.4 trillion won, just below the final figure of 89.5 trillion won (Reuters). Reuters reported that the final number was a 19-fold increase from a year earlier. Even so, Samsung's share price dropped after the earnings announcement (Reuters).

The market reaction likely reflects two concerns. The first is that the mobile loss breaks a pattern Samsung has relied on for decades. Because Samsung both makes memory chips and buys them for its own phones, the two sides of the business have traditionally balanced each other out: when memory prices fell, the chip division suffered but the phone division benefited from cheaper parts, and when prices rose, the reverse happened. In Q2 2026, that balancing act stopped working. Both sides of the business are now exposed to memory-chip prices at the same time.

The second concern is how long this lasts. Samsung expects the global chip shortage to extend to 2028, as reported by Reuters on July 30 (Reuters). That suggests the higher component costs pressuring Samsung's phone business are not a one-quarter problem but a multi-year one. If memory prices stay high through 2028, the profit margins on mid-range and budget phones, where Samsung sells in high volume, will keep getting squeezed.

Looking ahead, Samsung stated that in the second half of 2026, the mobile business plans to strengthen AI leadership (Samsung Newsroom). The company did not share specific product plans, but the language suggests Samsung wants to use on-device AI features to set its phones apart, which could help justify higher prices and reduce reliance on lower-margin, high-volume phone segments.

The broader context here is a company caught between two forces pulling in opposite directions. The AI-driven surge in memory-chip demand is producing record profits for Samsung's semiconductor business. That same surge is making it more expensive to build the phones Samsung sells, eroding the profitability of its handset business. For the first time, the internal balance that has defined Samsung's structure for decades has stopped working in one direction. Whether AI features in phones can help Samsung restore healthy profit margins is a question that will play out over the next several quarters, under the pressure of rising component costs that Samsung itself does not expect to ease before 2028.
