Just caught Ambiq's Q4 numbers and the stock jumped 8%+ on the news. Pretty interesting microstock move for a semiconductor company most people haven't heard of yet. They're basically the play on edge AI chips for battery-powered devices - think wearables, smart home stuff, that kind of thing. Their fourth quarter was their strongest all year, and management is already talking about more growth coming in Q1. What caught my attention though is they just closed that IPO and follow-on offering early this year, pulled in about $180 million in cash. That's a solid war chest for a company still building out their customer base. They mentioned Garmin as a major customer, which gives them some credibility. CEO said they expanded their customer base throughout 2025 and launched products for more complex edge AI applications. Not profitable yet, but that's pretty typical for semiconductor companies at this stage. The edge AI market is supposed to be huge, so if they can execute on that growth guidance they're talking about, early investors could see some real upside. Obviously buying pre-profitability comes with risk, but the Q4 momentum is definitely worth watching if you're into smaller semiconductor plays.
