Hi
EV SSL are not really used anymore but still available to purchase.
The reason for the decline is web broswers no longer dispalying the green bar and the mass introduction of Lets encrypt SSL.
The only clients we see buying paid SSL are usually for wildcard SSL and used on more then 1 server, so is easier for them
Many thanks

The green bar was a way of displaying this information loud and proud. When you visited a website with an EV SSL, Chrome, Mozilla, Safari, and Firefox would turn the address bar green, and display the registered company name in the address bar before the website URL.
Safari was the first browser to stop with the green address bar, with Google and other major browsers following suit soon after. Although Google removed the green bar with the release of Chrome version 69 in September 2018, it continued to display company information in the address bar until the release of Chrome 77 one year later.
Google explained why this change was being made, stating that “the Chrome Security UX team has determined that the EV UI does not protect users as intended”. The team found that the display could sometimes hinder rather than help, while wider security research indicated that it did not protect against phishing attacks as much as they hoped it would.
