Not seeing any filing with Nevada Secretary of State, yet.
I believe, if they get FINRA approval (after SEC approval), they will then file an amendment with Nevada (their state of incorporation). It will appear here: http://nvsos.gov/sosentitysearch/CorpSearch.aspx
Type in FONU, select FONU 2, then click under actions/amendments, when viewing FONU 2. There will be a #9 added dealing with the reverse split.
Again, I believe they have to get FINRA approval first.
