Samsung Flags a Record $80 Billion Quarter as the AI Memory Boom Lifts Chip Prices

Samsung Electronics just put a number on the memory shortage. On Thursday the company guided to third-quarter operating profit of 107.4 trillion won, about $80.2 billion, for the July-to-September period. That is up 782.5 percent from a year earlier and 20.1 percent from the prior quarter. Revenue is guided at 195 trillion won, up about 127 percent year on year and 14 percent from the second quarter. Both are company records. It is the fourth straight quarter Samsung has broken its own marks for sales and operating profit. Operating margin on the preliminary figures is about 55 percent. Nine-month operating profit is about 254 trillion won. Some Seoul notes already sketch a full year near 370 trillion won, and a 2027 figure far above that if prices hold. The guidance is preliminary. The divisional split — chips, phones, displays, appliances — comes with the full report on October 29. What Thursday’s filing does say is that the jump is the AI memory boom: high-bandwidth memory and server DRAM, sold into data centers that are still ordering faster than the industry can ship. How the Print Sits Against the Street Reuters said 107.4 trillion won was slightly ahead of an LSEG SmartEstimate of 106.1 trillion won. Yonhap Infomax had the beat at about 1.6 percent. Bloomberg’s read was cooler: a near nine-fold rise that still landed just shy of the most aggressive forecasts, with revenue also under the highest estimates, and the stock flat in early Seoul trade. A later Seoul session had the shares up about 0.3 percent against a softer KOSPI. The disagreement is about the whisper number, not the record. Crossing 100 trillion won in a quarter is a first for a Korean company and, on Reuters’ framing, a first for any technology company. Set against other tech profits reported this cycle, the won figure converts to more than recent quarterly operating profits cited for Nvidia ($63.7 billion in one comparison), Alphabet ($40.8 billion), Microsoft ($40.6 billion), and Apple ($35.7 billion). Those are different businesses and different quarters. The comparison is still the one Seoul is using: the company that sells the memory is, this quarter, more profitable than the company that sells the GPU. The second quarter had already been a record, at 89.4 trillion won of operating profit on 171 trillion won of revenue. Three months later Samsung added about 18 trillion won of profit. That is not a one-off shipment. It is a price. Where the Money Is AI data-center spending is buying two things Samsung sells. High-bandwidth memory, stacked next to accelerators, and conventional server DRAM and NAND, which have gone short because the same factories are being pointed at HBM. Prices on ordinary DRAM and NAND have risen because inventories are thin. Analysts expect conventional DRAM bit shipments to stay roughly flat for that reason, while HBM bits rise. Douglas Kim of Douglas Research Advisory estimated Samsung’s HBM bit shipments up close to 50 percent from the prior quarter. Samsung said on its July call that HBM4 revenue in the third quarter was expected to more than triple from the second, and that HBM4 would be well over 60 percent of HBM revenue in the second half. Samsung was first to mass production and shipment of sixth-generation HBM4. A meaningful earnings contribution from that part is still described as a next-year event. The third-quarter print is the shortage and the mix, not a single new chip. Chipmakers are now talking about the shortage lasting into 2028. If that holds, the 55 percent margin is not a peak-quarter curiosity. It is a supply contract the buyers cannot easily leave. The other side of the house does not get that price. The device unit — phones and consumer electronics — is expected to be the weak line when the October 29 split lands. Memory that Samsung sells to itself is memory its phone division has to pay for. Rising chip costs squeeze smartphone margins in the same quarter the chip division prints a record. U.S. tariffs are the other uncertainty Reuters flagged. A component boom and a handset squeeze can be the same company. What the Record Does Not Settle Four record quarters will be read as the end of the “AI bubble” argument and as the middle of it. Samsung’s customers are the same cloud companies whose capex guides have been the argument all year. If those guides are cut, HBM orders are the first line that moves. If they are not, a shortage into 2028 is a multi-year pricing power story for Samsung, SK Hynix, and Micron, and a cost story for everyone building a server. Shareholder returns are the other open item. Investors will look at the October 29 call for any change in the buyback or dividend policy after a quarter this large. A 55 percent operating margin throws off cash. What Samsung does with it — fabs, HBM capacity, or a return — is the next decision, not this one. What to Watch The October 29 split between semiconductors and the phone-and-appliance unit. HBM4’s share of memory revenue versus the “well over 60 percent” second-half guide. Whether DRAM and NAND prices keep rising into the December quarter. Any cloud capex cut that would hit 2027 orders. The shareholder-return comment on the earnings call. Samsung’s preliminary quarter is 107.4 trillion won of operating profit, about $80 billion, because AI infrastructure is buying more memory than the industry can ship. It is a record. It is also a preliminary filing. The phone business is the part of the company that has to live with the price the chip business just set.
