On September 10, Ambarella rose 8.41% in regular trading, trading at $68.57/share, with turnover of $178 million. The rally was primarily fueled by the ongoing fermentation of acquisition rumors involving NXP Semiconductors, combined with a technical rebound following better-than-expected Q2 earnings.

On the M&A front, reports emerged in early August that NXP Semiconductors was in talks to acquire Ambarella at a valuation of approximately $3.3 billion. Ambarella specializes in AI-powered chip design for autonomous driving camera systems and security applications. NXP, whose automotive chip business accounts for roughly half of its projected $14.2 billion annual revenue, would significantly strengthen its autonomous driving capabilities through the deal. Negotiations remain ongoing with no final outcome confirmed, and both companies have declined to comment.

On the earnings front, Ambarella reported Q2 adjusted EPS of $0.18, beating the consensus estimate of $0.17, while revenue of $108.1 million rose 13.2% year-over-year, also exceeding expectations. Despite the beat, post-earnings sentiment was mixed — Craig Hallum downgraded the stock to Hold and Bank of America lowered its price target from $96 to $70. The persistent acquisition speculation appears to have provided support for a technical rebound from oversold levels.
