Cary-based Dex One, a provider of yellow pages and Internet advertising services, is one step closer to moving its headquarters to Texas.

Shareholders on Wednesday approved the proposed merger with yellow pages firm SuperMedia (Nasdaq: SPMD), Dex One (NYSE: DEXO) said in an SEC filing.

SuperMedia has not disclosed its shareholders vote.

Dex One will move its headquarters to Texas where SuperMedia is based once the merger is completed.

Its shareholders voted nearly 100 percent in favor of the deal.

If the merger is successful, Dex One shareholders would own some 60 percent of the combined venture.

The deal was announced last August.
