Bain Case: Old Winery

You have inherited the “Old Winery” from your grandfather, a winery that has been family-owned for five generations and can be dated back to the 16th century. Half of the eleven hectares are used to grow white grapes, the other half to grow red grapes. They are grown in a conventional way, i.e. they are not organically farmed and certified. The vine stocks are in a good condition regarding age and care. Overall, the only ¼ of the harvest is made into wine by the winery itself; the rest is sold. Your grandfather never wanted to change the image of the winery and left the managerial and administrative task to a young and energetic wine-maker. Due to the not so well-known brand, the demand for the “Old Winery” wine is currently rather low. You do not intent to run the winery operatively, given your limited knowledge of winemaking, but find the idea of owning a winery exciting.

SunFury

Our client, SunFury, is a publically traded solar developer and the largest builder of utility scale solar projects across the US. They have experienced incredible growth over the last 6 years, due largely to the rapidly falling solar module prices from China and the consistent US tax credit forsolar projects. In 2017 the Solar Investment Tax Credit (ITC) will drop from 30% for all solar to 10% for utility and 0% for residential, forcing the industry to compete more closely with cheap coal and natural gas. It is August 2015, and SunFury has decided to expand their operationsinto the residential arena to better capture the ITC while it still exists. They have asked us to (1) estimate the potential value at stake, and (2) determine whether they should go ahead with their residential launch in 2016.
