Strong financial results prove that AI investments are paying off
Growing revenue 20% year-over-year, Amazon reported impressive Q2 2026 financial results yesterday, but what stood out was the company's considerable increase in its Amazon Web Services (AWS) business.
In the press release announcing Amazon's quarterly earnings, Andy Jassy, Amazon's president and CEO, stated, "AWS is booming, growing 36.7% year-over-year in Q2--our fastest growth in 18 quarters--and our AI and Chips businesses each eclipsed run rates of more than $25 billion."
In February, Amazon entered into a warrant agreement with Astera Labs that provides Amazon the option to purchase up to 3,262,299 shares of Astera Labs common stock upon the purchase of up to $6.5 billion of its smart fabric switch, signal conditioning, and optical engine products.
The strong performance of Amazon's AWS business is signaling to investors the value of the AI-connectivity solutions that Astera Labs has developed -- and perhaps opening the company up to interest from other hyperscalers.
Is now the time to buy Astera Labs stock?
Amazon's strong AWS growth is certainly a positive for Astera Labs, but it seems the market got ahead of itself, bidding the AI stock up sharply on the news. For those with Astera Labs on their radars, a more prudent move would be to see what the company reports in its quarterly earnings, expected next week.
