SEOUL — Samsung Electronics, the world leader in mobiles and memory chips, likely earned a quarterly profit of $8.1 billion, as it sold close to 500 handsets every minute and as demand picked up for the flat screens it makes for mobile devices, including those for rival Apple Inc. products. That run of five straight record quarters may end in January-March on weak seasonal demand, though a strong pipeline of smartphones - the South Korean group's biggest earner - and improving chip prices have eased concerns that earnings growth could slow this year, powering Samsung shares to record levels. “Guidance is unlikely to disappoint given new product launches and a further upturn in cyclical parts of the business,” said Morgan Stanley analyst Shawn Kim. “Smartphone momentum has not decelerated, despite Apple's new iPhone, and the business continues to be driven by its flagship products. “This time, it's the Galaxy Note II ... with the upside in unit shipments mainly from the US. We expect strong momentum to continue in the first quarter.” While Apple rolled out just a single new smartphone, the iPhone 5, last year globally, Samsung bombarded the market with 37 variants tweaked for regional and consumer tastes, from high-end smartphones to cheaper low-end models. By comparison, Taiwan's HTC Corp released 18 models, Nokia 9 and LG Electronics 24. Samsung, valued at close to $230 billion, gives its October-December earnings guidance Tuesday before the market opens. The full earnings release is expected by Jan. 25. Shipments of Samsung's flagship Galaxy S III, which overtook the iPhone 4S in the third quarter to become the world's best-selling smartphone, are likely to have slipped to around 15 million in the last quarter from 18 million in July-September. But estimated sales of around 8 million Galaxy Note II phone-cum-tablets, or “phablets”, should more than make up for that - pushing overall smartphone shipments to around 63 million, analysts estimate. There has been increased speculation that Samsung will launch the next version of its Galaxy S in the first quarter, possibly with an unbreakable screen and full high-definition quality resolution boasting 440 pixels per inch, as well as a better camera and a more powerful processor. “Samsung's smartphone shipments are likely to grow even in a seasonally weak first quarter. The early launch of the Galaxy S IV would drive second-quarter growth momentum,” said BNP Paribas Securities analyst Peter Yu, who predicts Samsung's 2013 operating profit will grow 25 percent to almost $35 billion. Samsung is forecast to raise its smartphone sales by 35 percent and widen its lead over Apple this year, driven by its diversified product line-up, said Neil Mawston, Executive Director at market researcher Strategy Analytics, which forecasts Samsung will sell 290 million smartphones this year, up from a projected 215 million in 2012. Apple's smartphone sales are projected to reach 180 million this year, up by a third from last year's 135 million. Samsung is likely to say Tuesday that its October-December operating profit increased 65 percent to 8.7 trillion won from a year ago, a Reuters survey of 16 analysts showed. That would be 7 percent higher than its previous record of 8.1 trillion won in July-September. Profits from the mobile division are seen slightly higher, at around 5.8 trillion won, than the previous quarter's 5.63 trillion won - and more than double last year's level. A recovery in chip prices and flat screens may have also boosted its component earnings, propelled by booming sales of mobiles carrying Samsung's chips, micro-processors and flat screens. Reflecting the upbeat outlook, shares in Samsung, Asia's most valuable technology stock, last week hit a life high of 1.584 million won ($1,500). The stock gained 44 percent in 2012, easily outpacing a 9 percent rise on the broader Korean market and topping Apple's 31 percent increase. The shares eased a third of one percent on Monday. Samsung, LG Electronics and four Taiwan companies were last week fined millions of dollars for allegedly manipulating liquid crystal display panel prices in China in 2001-06, the state-run news agency Xinhua reported. Meanwhile, in Cupertino, California, Apple said people have downloaded more than 40 billion apps on for the iPhone, iPad and the iPod Touch, nearly half of them in 2012. Apple Inc. said Monday that December saw record downloads of more than 2 billion apps. There are 775,000 individual applications available in the app store. Apple says it has paid app developers more than $7 billion. Apple launched its app store in 2008. The store hit the 10 billion downloads mark in early 2011. In March 2012, Apple announced that more than 25 billion apps have been downloaded. The 40 billion milestone does not include updates or re-downloads. — Agencies
