Southern Copper Q3 Posts Record Sales; PC Connection, Glaukos, Melexis Also Report Strong Results

Southern Copper achieved record Q3 sales and profitability, headlining a cluster of five companies posting strong results across mining, technology distribution, medical devices, and auto semiconductors.

• Southern Copper SCCO Q3 record sales and profitability as copper demand remains elevated
• PC Connection record net sales of $874M, up 23.3% YoY in Q3 2026
• Glaukos 58% YoY net sales growth, Melexis record China sales and BYD deal

Southern Copper's record Q3 sales reflect the sustained demand for copper from electrification and AI data center construction. Copper is the foundational conductive material in EV charging infrastructure, power grid upgrades, and the massive cable runs required in hyperscale data centers. With global copper mine supply constrained by permit delays and resource depletion at aging mines, the price environment has been constructive for integrated producers like Southern Copper, which operates primarily in Mexico and Peru. Record profitability at these volumes translates into significant cash flow generation.

PC Connection's 23.3% year-over-year revenue growth to a record $874 million reflects the enterprise technology refresh cycle and AI infrastructure investment wave reaching mid-market IT buyers. As a value-added reseller and IT solutions provider, PC Connection benefits from enterprises upgrading to AI-capable hardware, cloud-ready networking infrastructure, and managed services contracts. The 11% caveat flagged in the earnings commentary — likely related to a specific segment or margin item — bears watching but does not negate the strong headline growth.

Glaukos's 58% net sales growth in ophthalmology devices and Melexis's record China revenue from the BYD deal create additional diversity in the cluster. Glaukos's $211 million quarter reflects market share gains in its iStent (glaucoma drainage device) and Photrexa corneal cross-linking platform. Melexis's BYD relationship provides exposure to China's leading EV manufacturer through automotive semiconductor content — a high-value positioning in a market where local semiconductor sourcing is becoming strategically important to Chinese automakers.
