What 8x8, Inc. told the SEC could break it.
Most of what 8x8 flagged traces to its dependence on outside parties to run a cloud-telephony stack it doesn't fully own: it relies on third-party carriers to originate and terminate substantially all of its public-network calls and to supply phone numbers, buys IP phones and hardware from vendors that are in some cases sole-sourced, and sources telecom equipment internationally — leaving it exposed to tariffs and China-related trade tensions that could raise costs and limit supplier access. The other distinct exposure is geographic: a significant share of its engineering and operations sits in Romania, which borders Ukraine, and could be disrupted if the Russia-Ukraine conflict spread into surrounding countries.
4 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Geographic concentration
- engineering/operations concentration in Romania bordering Ukrainemedium
8x8 has significant engineering and operations presence in Romania, which borders Ukraine, so an expansion of the Russia-Ukraine conflict into surrounding countries could disrupt those operations.
“our significant engineering and operations presence in Romania which borders Ukraine, could be negatively impacted if the conflict were to expand into the surrounding countries.”
SEC filing →As of 2026
Regulatory & policy
- tariffs / trade tensions on internationally-sourced telecom equipmentmedium
8x8 sources telecom equipment internationally, so U.S. trade restrictions, tariffs and China-related trade tensions could raise costs and limit access to suppliers and markets.
“As we source telecom equipment internationally, trade tensions could have an adverse effect on our operations”
Sole-source dependency
- sole-source IP phone / hardware vendorsmedium
8x8 buys IP phones and hardware from third-party vendors, some sole-sourced; their inability to deliver acceptable-quality hardware on time could adversely affect operating results.
“The inability of these third-party vendors to deliver IP phones of acceptable quality and in a timely manner, particularly the sole source vendors, could adversely affect our operating results or cause them to fluctuate more than anticipated.”

Supplier concentration
- reliance on third-party network carriers for substantially all PSTN call origination/terminationmedium
8x8 depends on third-party network service providers to originate and terminate substantially all PSTN calls and to supply telephone numbers; disruption or cost increases from these carriers would hurt its business.
“We rely on third-party network service providers to originate and terminate substantially all of the public switched telephone network calls using our cloud-based services.”

Microsoft Corporation (Microsoft Teams)
“Microsoft Teams, or if problems arise with our relationships with providers of mobile operating systems, such as those of Apple Inc. or Alphabet Inc., our future growth and our results of operations could suffer.”
