From the figures I've seen, WPEngine is about 1% of that. (EDIT: oops, that was just their first year; didn't realize they've been around since 2010)
I haven't seen any credible news source pushing the "IPO" story here, just a bunch of "weird" news sources (maybe within the wordpress industry niche?) which TNW picked up. Or, a writer at TNW wrote a really breathlessly positive article about a company he personally liked, and threw the IPO thing in to make it interesting.
I'd bet on this being a weird marketing strategy for the WPEngine product; fake IPO rumors around a fairly mundane HR decision to get buzz and customers. If so, well played!
or three :). We've been around for a lot longer than folks realize - just been very "heads-down" building a strong business rather "TechCrunch Hype" focused, etc.
