Full Analysis
Applied Optoelectronics (AAOI) and MaxLinear (MXL) are competing suppliers in the AI data center infrastructure market, with AAOI focusing on high-speed optical transceivers and laser components, while MXL specializes in high-speed connectivity semiconductors like PAM4 DSPs. Both companies are experiencing significant growth driven by robust demand for next-generation products essential for hyperscale AI workloads. In the first quarter of 2026, AAOI reported datacenter revenues of $81.4 million, more than doubling from the prior year, fueled by volume shipments of 800G single-mode transceivers to major customers. The company has expanded its manufacturing footprint in Texas to support production scaling. Conversely, MXL saw a 43% year-over-year revenue increase with infrastructure becoming its largest category, growing 136%, driven by the ramping of its Keystone PAM4 DSP platform. Comparatively, MXL shares have risen 409.7% year-to-date versus AAOI's 212.9%, despite both stocks currently carrying a 'Hold' (Zacks Rank #3) rating and being considered overvalued. Analysts note that while AAOI faces production capacity constraints and supply chain limitations, MXL benefits from broader product momentum, sustained hyperscaler adoption, and more consistent earnings beats in the trailing four quarters. Forward-looking estimates show strong growth potential for both, with AAOI's 2026 earnings pegged at $0.80 per share (407% increase) and MXL's at $1.33 per share (329% increase). However, the article concludes that MXL appears to offer greater upside potential due to its consistent performance and expanding revenue visibility into 2027, whereas AAOI faces risks from intensifying competition and tariff uncertainties.
