No one knows the details of the agreement yet. It may not be a cash deal or only a partial cash deal. This could have been all or nearly all issued in stock.
Stock used to raise capital is the ONLY benefit and primary reason to becoming a public Company. If a Co is profitable enough with significant cash flow to expand and pursue growth internally, continually upgrade equipment and technology, add products and services and complete acquisitions there is absolutely NO reason to become public. Cargill being the largest and most successful example. Txhd $$$$$$$$
