Applied Optoelectronics Inc. (NASDAQ: AAOI) saw its shares climb 351% year‑to‑date after announcing a major expansion in Pearland, Texas, and a $200 million supply agreement.

The move matters because the added capacity targets 800‑gigabit and 1.6‑terabit data‑center optical modules, products that are in high demand as artificial‑intelligence workloads push networking speeds higher. The supply deal also reassures investors that the company has a reliable revenue stream to fund the growth.

The Pearland site now includes an additional 388,000 square feet of manufacturing space, a figure that triples the plant’s previous footprint and positions AAOI to meet the surge in AI‑driven traffic [2]. The company said the new floor area will enable production of next‑generation optical modules for hyperscale data centers.

Separately, AAOI secured a $200 million supply contract with an unnamed tier‑one customer, a deal that the firm said will lock in demand for its 800G and 1.6T products for the next several years [3]. The agreement is expected to generate steady cash flow and support the capital outlays required for the Texas expansion.

Investors have responded strongly. The stock rose 44.9% week‑on‑week in early April, after the expansion and supply‑deal news broke [4], and jumped 15% in a single Monday session following the press release [5]. The cumulative effect is a 351% rally so far this year [1], lifting AAOI to an all‑time high on the Nasdaq.

Analysts said that AAOI’s growth strategy aligns with broader industry trends, as cloud providers and hyperscale operators scramble to upgrade their optical interconnects. The company’s ability to scale manufacturing quickly could give it a competitive edge in a market where speed and volume are critical.

The Texas expansion adds 388,000 square feet of capacity.

What this means: Applied Optoelectronics' aggressive capacity build and secured supply contract have positioned it to capture a fast‑growing segment of the data‑center market, translating into a dramatic share price increase that reflects both investor optimism and the broader AI‑driven demand for high‑speed optics.
