Update on full year results

Wednesday 13th of July 2011: Uscom (ASX code: UCM).

Uscom Limited advises that, based on preliminary financials, the company expects its reported revenues from ordinary operations to be in line with the previous year but estimates the loss for the year will increase around 45% on the previous period to $2,869k (Loss $1,978k 30 June 2010).

Expenditure has increased predominantly in relation to the implementation of the US marketing strategy which has seen a number of new distributors signed to company. This is a significant investment for the future and will be a positive impact on revenues in going forward.

Significantly for FY11 results, the company will incur a large expense related to vested options which accounts for approximately 40% of the increase in expenditure or $332k.

The results reflect the major change in strategy adopted after the termination of the company’s relationship with Spacelabs, the exclusive distributor for all markets except Asia Pacific in December last year.

Since the beginning of the calendar year the company has focused on signing new distributors globally and this has resulted in 6 appointments in the North American market, 4 in Europe, 1 in South Africa, 1 in the Middle East and 2 in Latin America. The company has also enhanced its Asia Pacific distribution capability with the appointment of a senior business development executive to drive sales results across this important high growth market.

The company expects that the benefit of these intitiatives should materialise during the course of the 2011-12 financial year in the form of sales growth and shareholders will be kept advised in this regard.
