I agree with @Thunderhead that "ultimately there is value looking out long-term - a decent risk/reward proposition."
However, I think it might be undervalued (disclosure I hold) when one considers the renegotiation of the purchase price and the fact the earn out bonus that was to be paid is basically gone.
So if we consider the price before the Ireland issue (~6.00), the recalculation of the purchase price of PCSIL, the elimination of the earn out bonuses as a result of this fiasco + the recent significant value the purchase of Sentenial brings and balance this against the possibility of future revenue the Irish component may face, additional regulatory costs and the CIB fines then, it seems to me that EML although facing short term headwinds in Ireland has potentially acquired an asset at fire sale prices.
In the short term the market looks like it will price EML based on the unknown with this CIB investigation. Therefore, until this issue is settled and investors return to focusing on the underlying company fundamentals this is probably going to be a traders paradise.
