“Win-Win Opportunity” in Process

1. Reaction to the MOE

Since news of the hiSoft-VanceInfo merger was released on August 10th, 2012, we have seen a great deal of interest expressed from the media, the market, government departments and, of course, hiSoft employees.

As the initial surprise of the announcement has worn off, many people are expressing strong enthusiasm for the merger and are seeing the Merger of Equals (MOE) as a true “win-win opportunity.”

This positive sentiment is being echoed in the media as well. A mainstream publication recently commented that this merger is much more than an act of “mutual assistance.” It characterized the merger as a landmark transaction creating a pivotal new entity capable of leading the overall global competitiveness of China’s IT service & software outsourcing industry. The writer further expressed the view that such a goal was fully in line with the aggressive corporate cultures of both hiSoft and VanceInfo and that neither company would have been satisfied with a transaction goal of mere “mutual assistance.”

With an estimated combined annual revenue of over US$670 million, the newly formed entity will have the critical commercial mass to command attention and assert influence on the world outsourcing stage. In the same way a mighty aircraft carrier is a proud symbol of a nation’s strength, the newly merged entity will serve as a flagship carrier for China’s outsourcing industry in the global arena.

Naturally, a vessel of this size will create accelerated development opportunities in new markets, service lines and career paths. We have already been approached by two top software vendors to discuss wide-scale partnerships and several municipal government entities about growth plans. Clearly, the expanded eco-system is already taking note of the new potentials to be brought about by the merger and there will no doubt be more on the way.

In the coming days as integration planning sharpens in focus, let’s continue to diligently serve our customers with excellence. Let’s also move forward in a spirit of open-mindedness and cooperation as we explore and evaluate new horizons. This merger will be a defining point in the history of Chinese-based outsourcing companies. With the right attitudes in place now and our continued hard work, we can all do our part to ensure the merger is successful and reaches the heights of its true potential.
