Legacy Stocks Power the AI Boom with Physical Advantages

Investors often overlook older technology sector names, assuming their prime growth years are over. However, looking beneath the surface reveals how foundational hardware suppliers adapt to infrastructure transitions and capture substantial value.

Corning Incorporated (NYSE: GLW) is one such legacy stock that has strategically redirected its commercial footprint from consumer display panels toward optical communications for hyperscale data centers.

The company has secured a long-term agreement with Verizon to supply over 80 million miles of optical fiber between 2027 and 2032, providing it with significant visibility. Corning is also demonstrating high-density 1060-nanometer optical die-to-die connectivity at ECOC 2026 to speed up data movement between parallel processors.

With a market capitalization of around $136.70 billion, Corning trades near $159 and has produced an 11.20% net profit margin, an operating return on equity (ROE) of 20.09%, and operating cash flow of about $4.35 per share in the second quarter.

Cisco Systems, Inc. (NASDAQ: CSCO), another legacy stock, has shifted from traditional network switching to an integrated software and cybersecurity provider. The company provides the visibility organizations need to protect proprietary data across distributed networks by uniting network telemetry with specialized security architectures alongside NVIDIA.

Texas Instruments Incorporated (TXN) designs essential components that interface digital brains with physical machinery, positioning it at the heart of automotive electrification and smart factory automation. With a net profit margin of 31.11%, an ROE of 35.77%, and cash flow of about $7.72 per share, Texas Instruments is well-positioned to benefit from the ongoing transition to AI infrastructure.
