Particularly, should the company go public, stay private or should it sell its business altogether? The answer to this question is rather straight forward, and it sees that the company should stay private. In addition to this, it should continue to prospect the market and negotiate with prospective buyers in order to further assess its market value. The rationale for the recommendation to stay private is represented by the following:

Nantucket Nectars has attained financial stability and profitability by itself, through a well crafted and executed business model, which should be preserved

The company is following an ascendant path that could be jeopardized by sudden movements

The current economic climate is quite unstable and propels economic agents, including Nantucket Nectars, to focus on...

In this instance, the company is obliged to make the decisions which best serve its stakeholders in the long-term. Specifically, Nantucket Nectars has the obligation to ensure the long-term stability of the jobs of its employees, as well as the long-term stability of the return on the investments made by the investors. This long-term stability could now be jeopardized if the managerial team at Nantucket Nectars decided to sell, go public or approve its acquisition by either of the five firms negotiating with it.
