0859 GMT [Dow Jones] Stanelco (SEO.LN) update is "less specific than we would have liked" regarding Greenseal, says Teather & Greenwood. Suspects retrofit program is now behind plan. Notes company mentions potential of 80 machines out of 200 for the Asda contract. Teather's forecast for 06 is already significantly below consensus and as it relies on completion of Asda contract on time, risk "must be on the downside." Teather isn't changing forecasts at this stage. Still likes Greenseal but wary over delivery. Believes too much potential is being built into valuation too early. Hold rating.
