澜起科技在7月15日至17日短短三个交易日内遭遇股价暴跌。[1]股价从15日的275元开始下挫，16日跌幅达16.44%，17日再下跌13.04%，三天累计跌幅超过30%。[1]这轮下跌导致公司A股市值蒸发逾800亿元，港股市值三天内蒸发超2000亿元。[1]
股价暴跌的直接触发因素是韩国监管部门的突击搜查。[1]韩国首尔中央地方检察厅以涉嫌违反《公平交易法》为由，突击搜查了澜起科技、瑞萨电子和Rambus三家公司的韩国办公室，调查涉嫌串通半导体零部件价格。[1]作为全球芯片市场的主要参与者，澜起科技全球市占率36.8%排名第一，与日本瑞萨电子、美国Rambus三家合计占全球93.4%的市场份额。[1]公司71.5%的营收来自境外市场，主要客户包括三星电子、SK海力士等。[1]
与此同时，澜起科技发布了上半年业绩利好。[1]上半年营收达33.35亿元，同比增长26.6%，归母净利润预增63.9%至81.2%，达到19亿至21亿元。[1]董事长杨崇和还提议以3至6亿元自有资金回购A股股份。[1]然而这些积极信号未能抵消反垄断调查带来的市场恐慌。
Luokesai Technology experienced a severe market downturn over three consecutive trading days, with its stock price plummeting over 30% between July 15 and 17 [1]. The A-share market capitalization evaporated by more than 800 million yuan, while Hong Kong-listed shares lost over 2,000 billion yuan in value across the same period [1]. The sharp decline was triggered by South Korea's Seoul Central District Prosecutors' Office conducting surprise raids on the Korean offices of Luokesai Technology, Japan's Renesas Electronics, and the United States-based Rambus, all suspected of violating the Fair Trade Act through alleged collusion in semiconductor component pricing [1].
The stock selloff stood in stark contrast to the company's simultaneous release of positive first-half results. Luokesai reported revenue of 33.35 billion yuan, representing 26.6% year-over-year growth, with net profit attributable to shareholders projected between 19 billion and 21 billion yuan, a 63.9% to 81.2% increase compared to the same period last year [1]. The company also announced that its chairman, Yang Chonghe, proposed repurchasing between 300 million and 600 million yuan worth of A-share stock using company funds [1].
Luokesai holds the largest global market share in its sector at 36.8%, with Renesas and Rambus collectively commanding significant portions; the three companies together account for 93.4% of the global market [1]. The company derives 71.5% of its revenue from international markets, serving major clients including Samsung Electronics and SK Hynix [1].
