Work stopped on the City of London site last January as the developers struggled to raise funds for the tower.
Brookfield Multiplex launched a legal claim for outstanding payments late last year against the Pinnacle owners who were ordered to pay the firm £16m.
Brookfield Multiplex has now confirmed it has reached a settlement and will now work with the developers to get the scheme going again.
A company statement said: “Brookfield Multiplex can confirm that an agreement has been reached on outstanding payments relating to construction work already carried out and as part of the settlement Brookfield Multiplex will now work with the investors to refine the scheme.”
