Cisco Systems (CSCO) primarily sells its products and services to other companies, governments, and service providers, rather than directly to individuals. Its customer base is highly diversified across various industries and geographic regions, with no single customer typically accounting for 10% or more of its total revenue, as per its financial filings.

Despite this diversification, Cisco serves large organizations that require extensive networking hardware, software, security, collaboration tools, and related services. These customers can be broadly categorized as:

1. Service Providers: Telecommunications companies, internet service providers (ISPs), and cable operators that build and operate large-scale networks. These companies are major purchasers of Cisco's carrier-grade routers, switches, optical networking equipment, and software for their infrastructure.
2. Enterprises: Large corporations across virtually all sectors, including financial services, manufacturing, retail, technology, healthcare, and more. These businesses utilize Cisco's full suite of products for their data centers, campus networks, security, collaboration (e.g., Webex), and IoT solutions.
3. Public Sector: Government agencies (federal, state, and local) and educational institutions, which also have significant needs for robust, secure, and scalable network infrastructure.

While Cisco does not disclose specific individual "major customers" due to the breadth of its client base and client confidentiality, the following public companies are prominent examples of organizations within the Service Provider category that are very likely significant customers for Cisco due to the scale and nature of their operations:

• AT&T Inc. (Symbol: T)
• Verizon Communications Inc. (Symbol: VZ)
• Comcast Corporation (Symbol: CMCSA)
• Deutsche Telekom AG (Symbol: DTEGY)
• BT Group plc (Symbol: BT)

These companies represent the types of large, public entities that invest heavily in the kind of networking and IT infrastructure that Cisco provides.

• Flex Ltd. (FLEX)
• Jabil Inc. (JBL)
• Broadcom Inc. (AVGO)
• Intel Corporation (INTC)
• Marvell Technology, Inc. (MRVL)
• Micron Technology, Inc. (MU)
• Analog Devices, Inc. (ADI)

The clear emerging threat to Cisco Systems (CSCO) is the rapid and accelerating industry shift towards cloud-native Secure Access Service Edge (SASE) and Zero Trust Architecture (ZTA).

Cisco's traditional business model has long revolved around selling on-premise networking hardware (routers, switches) and security appliances (firewalls, VPNs) designed for a perimeter-based security model. SASE and ZTA represent a fundamental disruption to this approach. SASE converges networking and security functions—such as SD-WAN, Firewall-as-a-Service, Secure Web Gateway, Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA)—into a single, cloud-delivered service. ZTA, meanwhile, mandates verifying every user and device trying to access resources, regardless of their location, eliminating implicit trust within a network.

This paradigm shift directly challenges Cisco's established revenue streams by diminishing the need for discrete, on-premise hardware and traditional network security stacks. Competitors like Zscaler, Palo Alto Networks (with Prisma SASE), Fortinet (with FortiSASE), and Netskope are leading this movement, offering integrated, cloud-first solutions that streamline operations and reduce the total cost of ownership for enterprises. While Cisco is actively developing and acquiring its own SASE and ZTNA capabilities (e.g., Cisco Secure Access, ThousandEyes for SASE, integrations with SD-WAN), the foundational change in how network and security services are consumed—moving from hardware-centric to cloud-native and service-oriented—poses a significant threat to its core business. This shift is comparable to how Netflix's cloud-based streaming model rendered Blockbuster's physical stores obsolete, or how the iPhone's integrated, app-ecosystem approach disrupted BlackBerry's hardware-focused, secure communication devices.

Cisco Systems (CSCO) is anticipated to drive future revenue growth over the next two to three years through several key strategic initiatives and market trends:

1. Surging Demand for AI Infrastructure

Cisco is experiencing significant demand for its networking infrastructure to support artificial intelligence (AI) workloads, particularly from hyperscalers and enterprises building out their AI data centers. The company secured over $2 billion in AI-related orders in fiscal year 2025, more than doubling its initial target. This growth is fueled by new AI-centric products, such as the 8223 routing system and integration with NVIDIA's Spectrum-X Ethernet technology, designed to modernize networks for AI applications.

2. Expansion of Security Solutions and Splunk Integration

The acquisition and ongoing integration of Splunk are substantially bolstering Cisco's cybersecurity division, contributing significantly to revenue growth. Security revenue has seen considerable year-over-year increases, with Splunk's analytics tools being a pivotal component. Additionally, new and next-generation products like Hypershield and XDR (Extended Detection and Response) are further fueling this momentum by addressing the escalating demand for advanced threat protection.

3. Shift to Software and Subscription-Based Business Models

Cisco is actively transitioning its business model from primarily hardware-focused to a software and subscription-driven approach. This strategic pivot has led to consistent growth in software revenue and Annual Recurring Revenue (ARR), with subscription revenue now representing a substantial portion of the company's total revenue. This shift creates more predictable income streams and is aligned with how customers increasingly prefer to consume technology.

4. Network Modernization and Campus Refresh Cycles

A significant driver of future revenue growth is the large installed base of aging network equipment (estimated to be 5-15 years old) that requires upgrades. Analysts project a multi-year campus refresh cycle, with businesses investing in upgrades to AI-enabled Smart Switches and other secure, intelligent network infrastructure to support digital transformation and the integration of AI.

Share Repurchases

• Cisco repurchased approximately $5.995 billion in common stock during fiscal year 2025.
• The company's annual share buybacks were $5.787 billion in 2024, $4.293 billion in 2023, and $7.689 billion in 2022.
• As of July 26, 2025, Cisco had approximately $14.2 billion remaining under its stock repurchase program, with no termination date.

Outbound Investments

• Cisco completed the acquisition of Splunk for $28 billion in March 2024, a strategic move to bolster its data analytics, AI, and cybersecurity capabilities. This acquisition significantly increased net acquisitions to approximately $26 billion in fiscal year 2024.
• In 2021, Cisco closed 11 global acquisitions, including Acacia Communications, which was noted as one of its most significant deals in recent years.
• Cisco has a US$1 billion investment fund as part of its AI strategy and is actively making opportunistic acquisitions and investments in AI startups to accelerate its vision.

Capital Expenditures

• Cisco's capital expenditures for fiscal year 2025 were $905 million, marking a peak in the last five years.
• Capital expenditures were $670 million in fiscal year 2024 and $849 million in fiscal year 2023. The average capital expenditures from fiscal years 2021 to 2025 were $718.6 million.
• The company's capital expenditures support its strategic focus on building infrastructure for the AI era, including network optimization and AI-native management tools for data center environments.
