The stock’s rally followed a strong Q2 earnings report, with non-GAAP earnings of $0.44 per share, exceeding estimates by 33.33%. Revenue grew 149.7% year-over-year to $192 million, driven by demand for PCIe 6 products and Scorpio Fabric switches for AI infrastructure.

Non-GAAP gross margin is expected to remain near 75%, with operating expenses forecasted at $76–80 million. Analysts highlight Astera’s strategic partnerships, including integration of NVLink Fusion with NVIDIA, as a key growth driver. The firm’s focus on rack-scale AI systems and signal conditioning solutions aligns with rising demand for high-speed connectivity in data centers. Despite elevated R&D costs, the company’s operating margin expanded to 39.2% in Q2, up from 24.4% a year earlier.

Astera’s stock has gained 200% from April lows, supported by technical indicators such as the 50-day and 200-day moving averages. Institutional buying and revised earnings estimates suggest continued momentum. The Zacks Internet – Software industry group, where Astera is classified, ranks in the top 32%, indicating potential outperformance against broader markets. Analysts at Evercore ISI praised the “Big Beat, Big Raise” in Q2 results, signaling strengthening sector momentum. With Q3 guidance exceeding expectations and a robust balance sheet, the stock remains a focal point in AI infrastructure investing.
