I'm using SilverStripe ORM.

I need to get all companies that are at least in ALL of the desired Specializing (no less):

class CompanyPage extends Page {    
    private static $many_many = [
        "Specializings" => "Specializing",

class Specializing extends DataObject {
    private static $belongs_many_many = [
        "CompanyPages" => "CompanyPage",

I have an array filled with desiring specializing ids ( $specIds ).
This gets companies that are at at least in one of the desired specializing, but it isn't that I need.
$companyPages = CompanyPage::get()->filter([
    "Specializings.ID:ExactMatch" => $specIds,

I can achive my task with this SQL-query
select * from CompanyPage c1 join (
  select c.ID from CompanyPage c 
  join CompanyPage_Specializings cs on cs.CompanyPageID = c.ID
  where cs.SpecializingID in (14,15)
  group by c.ID having count(c.ID) = 2
) c2 on c1.ID = c2.ID

But how can I achive it with SilverStripe ORM?
I can't find anything about having by aggregated functions in ORM
