CMC Telecom
Vietnam's #4 telecom/cloud/data-center provider, backed by Samsung SDS as owner and anchor client.
On the record
Checkpoint: Saigon Hi-Tech Park $250M hyperscale data center groundbreaking
The call
CMC Telecom sits inside a four-firm oligopoly with a captive Samsung customer, while its growth hinges on hyperscale projects that haven't broken ground yet.
CMC Telecom runs data centers, cloud services, and telecom infrastructure in Vietnam as part of a four-company oligopoly that controls almost all the market. It is hard to replace quickly because it owns physical buildings and fiber cables, has government licenses, and Vietnam's 2026 data-privacy law requires customer data to stay in-country. But the company's growth story depends on two massive new data centers that have not been built yet, and American companies like Amazon Web Services and Google may enter Vietnam's market after new rules relaxed restrictions on foreign competitors. If those new data centers do not get built on time due to power shortages, or if AWS and Google announce plans to operate in Vietnam within the next year and a half, investors may have to rethink how much the company can grow.
Why
01
AI pressure: AWS, Google Cloud, Alibaba Cloud AI/region services. Foreign hypercloud AI services could route Vietnamese AI workloads offshore if data-residency rules loosen before 2026. Could AI do the core job? Unlikely.
02
Bigger players: Viettel IDC. State-backed Viettel IDC already runs the country's biggest data-center footprint, dwarfing CMC's planned builds. Could a giant copy it? Probably.
03
What protects it. Samsung SDS's 30% stake and roughly $1B backing plus Vietnam's 2026 data-residency law keep captive demand and licenses in CMC's favor.
What would change this call
Saigon Hi-Tech Park $250M data center breaks ground on schedule in 2026. Shows CMC can convert roadmap capacity claims into shipped infrastructure.
AWS or Google announce a Vietnam region or major colocation presence within 18 months. Would materialize direct foreign hyperscaler competition rather than partnership.
CMC discloses standalone CMC Telecom revenue separate from parent CMC Corporation. Would reveal whether the subsidiary is growing in line with or lagging parent growth.

Key numbers
- Samsung SDS holds ~30% stake, ~$1B invested
- CMC Corp FY2026 revenue VND9.56T, +16.6% YoY
- CMC ADI data-center unit spun off July 2024
Named risks

- $250M and $1.3B flagship projects remain roadmap-stage MoUs/approvals, not shipped facilities.
- Foreign hyperscalers gaining direct market entry rights since 2024 liberalization.
- No standalone financial disclosure for CMC Telecom obscures true subsidiary performance.
- Viettel's larger existing scale (140MW) could cap CMC's market share gains.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Viettel IDC | gaining on | 140MW Tan Phu Trung campus already operating vs CMC's 30-120MW project still pending, as of 2025 |
| VNPT | contesting | Competes for government and sovereign-cloud contracts within the same ~97% four-player oligopoly, 2025 |
| FPT Telecom | contesting | Holds share within Vietnam's four-player data-center oligopoly alongside CMC, 2024-2025 |
| AWS, Google, Alibaba, Meta | gaining on | Eligible for 100% ownership entry since July 2024 liberalization, no Vietnam region announced yet as of mid-2026 |
Questions people ask
- Is CMC Telecom profitable?
- CMC Telecom's parent, CMC Corporation, reported group pre-tax profit over VND 500 billion on more than VND 8.2 trillion revenue for 2024, per Chairman Nguyen Trung Chinh's statement dated September 8, 2025. No standalone profit figure for the telecom subsidiary itself is publicly disclosed.
- Who owns CMC Telecom?
- CMC Telecom is a subsidiary of Vietnam's publicly listed CMC Corporation (HOSE: CMG). South Korea's Samsung SDS holds roughly a 30% stake in the parent, with cumulative investment reported near $1 billion, confirmed as of September 24, 2019.
- Could AI replace CMC Telecom?
- Unlikely soon. CMC Telecom's core business is physical infrastructure, Tier III data centers, fiber, and government licenses, that AI cannot replicate. AI is instead a demand driver: CMC runs a GPU farm exceeding 1,000 Nvidia GH200 units as of July 2025 to serve AI compute customers.
- Who is CMC Telecom's biggest competitor?
- State-owned Viettel IDC is the dominant rival, operating a 140MW Tan Phu Trung data-center campus versus CMC's planned 30MW-to-120MW Saigon Hi-Tech Park facility approved in July 2025. Viettel, VNPT, FPT, and CMC together hold about 97% of Vietnam's data-center market as of 2025.
- Will CMC Telecom's $250 million data center actually get built?
- Approval was granted in July 2025 for a $250M, 30MW-scalable-to-120MW hyperscale data center in Saigon Hi-Tech Park, with groundbreaking targeted for 2026. Northern Vietnam grid constraints are a cited risk that could delay construction timelines.
- What is CMC Telecom's revenue?
- CMC Telecom does not disclose standalone revenue. Its parent, CMC Corporation, reported group revenue of VND 9.56 trillion for fiscal year ended March 31, 2026, up 16.6% year over year, following VND 8.20 trillion in FY2025.
