AIM - WINNERS

----------

SRT Marine Systems PLC, up 18% at 54.2 pence, 12-month range 23.6p-58p. The provider of maritime domain awareness systems and technologies for surveillance, security, safety and environmental protection rises on a contract win. Signs a USD180 million contract to supply integrated maritime surveillance and intelligence systems to an unspecified national Coast Guard. Says signing took place in "confidential ceremony" at coast guard headquarters on Wednesday. The project is expected to take two years to implement, with support and data services period of eight years afterwards. "We look forward to a long relationship with our expectation of this being just the first of many contracts in the years and decades to come," says CEO Simon Tucker.

MyHealthChecked PLC, up 16% at 25.43p, 12-month range 16.5p-38.1p. The consumer home-testing healthcare company signs a contract with Boots UK Ltd to launch an extended range of its products on boots.com and across Boots stores in the UK. Says contract is via its Concepta Diagonstics Ltd subsidiary. Under the agreement, Boots will stock 14 of its different test panels, launching from May this year. The tests and sample collection kits will be available for tests of thyroid function, food intolerances and sensitivities, and vitamin profiles. "Following the launch of our extended product portfolio, our focus will turn towards ongoing customer guidance as we self-fund our investment in the evolution of our technology platform," says CEO Penny McCormick.

AIM - LOSERS

----------

IQE PLC, down 14% at 20.15p, 12-month range 19.75p-60.8p. The Cardiff-based semiconductor company raises GBP30 million in placing of 150.0 million shares at 20p each, with the issue price a 15% discount to Wednesday's closing price of 23.5p. On Wednesday, IQE said the fundraise was in order to ensure that the company can continue to invest to execute on its strategy, meet its near-term liquidity requirements, and deliver a sustainable balance sheet position going forward.

----------

Christie Group PLC, down 14% at 129.95p, 12-month range 100p-154.9p. The provider of professional and financial services, stock and inventory services to several sectors says full-year performance will have a "more pronounced second-half weighting" than previously expected. This is a result of "the coincidental sale of exceptionally large portfolios of Dental, Pharmacy and Care Home assets on unit by unit bases", the firm says. Due to the timings, the industry's business mortgage lending teams and "specialist non-conflicted" chartered surveyors are fully utilised, causing a delay to lead times. This has led to a backlog of transactions, pushing some of the first-half revenue into the second half.
