Microsalt (SALT) tried to raise £10-15 million ahead of an IPO last October but for some unexplained reason, Nomad Zeus postponed the IPO. On 1 February it joined the AIM sewer after raising £3.15 million gross (£2.5 million net) at 43p giving an £18.5 million valuation. Today, after announcing what it termed a “vital” deal earlier this week, the shares are 112.5p so valuing it at just over £48 million. Really?
