its pretty unstable for most valuation methods at this point. its cheap in terms of price/sales compared to others in its group. FRDM, PPS = 0.026, P/S = 2.24 for example, DRS Inc. (Public, PINK:DRSX) has a PPS of 0.360 and a P/S = 11.85. the most important thing here is that the company is profitable and is sustainable.
