🔴 CSCO is trading 3.0% down today after CFO flags AI-related margin pressure

CSCO is trading 3.0% down at $115.27 after the company's CFO warned of potential margin headwinds. The stock is also reacting to reports of a recently disclosed, actively exploited SD-WAN vulnerability.

• At a JPMorgan Chase technology conference, Cisco CFO Mark Patterson stated that the company's move to supply hardware for AI hyperscalers “comes at a different gross margin play” and would be a “headwind.”
• This news overshadowed the recent disclosure of a maximum-severity authentication bypass vulnerability (CVE-2026-20182) in its Catalyst SD-WAN platforms, which was confirmed to be actively exploited in May 2026.
• The selling pressure is occurring amidst a broader tech sector retreat driven by higher Treasury yields.
