AAOI manufactures components for data centers, enhancing cable TV/Broadband speeds, and facilitating rollouts. The company has not earned a profit since 2017 and has hemorrhaged cash. It has plugged the hole by issuing more shares. However, it has seen a recent turnaround in sales, which has excited the market. The stock was trading under $2 in 2023 and surged to over $40 in late 2024, driven by the stronger sales growth. However, AAOI’s sales growth has leveled off, with guidance for Q3 sales of $115-$127 million, yet it still expects to lose money, with non-GAAP EPS forecasts calling for a loss of $0.10 to $0.03 per share.
