When a software product becomes end-of-life it means that the software will no longer be updated or supported.

The issue will be security updates. It will only be a matter of time before someone uncovers a backdoor into the Magento 1 system and spreads this information around the web.
With no updates to fix this, your website will then be open to any attackers to take control of it and potentially access all your data. You are legally responsible for your data and so will potentially be responsible for the fines and losses incurred.

You need to urgently switch your store to a system which has full support and ongoing updates.
You have probably already considered and rejected Magento 2 because of the extra costs and the prospect of having to do this all over again when they change it to Magento 3.
