Only by reviving it. The classification requires a real and operating commercial enterprise, so a business that has been dormant for seasons is not one the investor can simply purchase and present. The purchase can still work, but the evidence has to show the enterprise trading again, with the investor's capital irrevocably committed and at risk in doing so.
Buying the assets of a stopped business is not buying an enterprise
A dormant company is a container. What the classification looks for is activity: goods or services actually being supplied, customers, staff, insurance, licences and a bank account with movement in it. An investor who takes over a shuttered operation therefore has more to prove rather than less, because she must show both the commitment of capital and the restart.
Hypothetical example: a purchaser from Sainte-Cécile-de-Milton agrees to buy a Vermont field nursery that has not sold a tree in two seasons, and whose stock has grown out of saleable size. Presenting the signed agreement proves nothing about operations. What would help is a file showing replanting orders placed, the irrigation system repaired and paid for, two seasonal staff hired, a supply contract signed with a landscaper, and the escrow released so that the money is beyond recall.
The enterprise must also promise more than a minimal living, which for a nursery of that size is a question about acreage and contracts rather than about enthusiasm.
