Samsung Mobile Slides to $448.5M Loss as Memory Boom Drives Record Quarter

Samsung Electronics' smartphone and networks division lost KRW600 billion ($448.5 million) in the third quarter, even as the group as a whole posted a record quarterly net profit of KRW75.1 trillion on surging demand for AI memory chips. The swing is stark: the same unit earned KRW3.6 trillion in the corresponding quarter a year earlier.

The division, formally branded Mobile eXperience and Networks, grew revenue 11% to KRW37.7 trillion. Sales strength did not translate into profit. Samsung said its latest flagship smartphones and its foldable range drove the top line, but cost pressures hit the bottom line — a problem the company had already flagged when it reported its second-quarter results.

What went wrong in mobile?

The arithmetic is simple. Handsets sold well, but the cost of building and selling them rose faster than the prices Samsung could charge. The company offered little detail beyond that, repeating the explanation it gave three months ago.

Samsung's stated remedy for the current quarter is a push on premium handsets and new related products, alongside an effort, in its own words, to "mitigate profitability risks through efficiency improvements across all business processes."

Looking further out, the company plans to reorient its device business in 2027 around two priorities:

• Concentrating on flagship devices and delivering, as Samsung put it, "differentiated experiences by customer segment"
• Pushing "hardware and form-factor innovation"

To "minimize declines in profit," Samsung said it will rely on "agile market responses and operational efficiency initiatives." The phrasing suggests management expects the squeeze to persist rather than reverse on its own.

The Networks side of the division had its own troubles. Earnings declined on lower sales in North America and reduced sales of high-margin software. For the current quarter, Samsung is targeting revenue growth in three markets: North America, Japan and its home base of South Korea.

How big was the memory windfall?

The contrast between the two halves of Samsung's business could hardly be sharper. Group-wide, net profit jumped from KRW12.2 trillion a year ago to KRW75.1 trillion. Revenue climbed 127% to KRW195.3 trillion. Samsung described these figures as a quarterly high, driven by demand for memory products — the chips that power AI training and inference in data centers.

One number frames the story: a division that once generated KRW3.6 trillion of quarterly profit now consumes KRW600 billion, while the memory business carries the entire company. That imbalance is the strategic backdrop for every plan Samsung laid out for 2027.

Samsung was bullish on the outlook. The company said it expects "industry-wide competition for AI leadership to drive continued AI infrastructure investment" in the current quarter. For 2027, it anticipates "AI infrastructure capital expenditure to reach an historic level."

For Samsung's device customers and carrier partners, the message from Seoul is that patience is required. The mobile unit does not expect relief this quarter; its recovery plan rests on premium-focused sales, efficiency work and a 2027 product strategy built on flagships, segmented experiences and new form factors.
