Update on Half year results

Thursday 27th of January, 2011: Uscom (ASX code: UCM).

Uscom Limited announced on the 14[th] of January 2011, that it expected its results for the period ending 31 December 2010 to be lower than the corresponding period ending 31 December 2009. This was based on preliminary draft management accounts.

Uscom Limited provides further information based on work completed for its audited accounts and confirms as previously announced the net loss for the period ending 31 December 2010 is expected to be $1,052m ($830k 31 December 2009). This represents a $222k variance which is a 26% change from the corresponding period.

Revenues from ordinary operations were down 24% from $635k to $481k (down by $154k). This is now determined as primarily due to the slowdown in sales due to the Obama health reforms, subsequent conclusion of the Spacelabs agreement and the impact of foreign exchange.
