MERLIN DIESEL SYSTEMS LTD
Company number 02539463 · Monitor this company
Executive summary
Merlin Diesel Systems Ltd is a fundamentally healthy business with strong profitability (operating profit up 6.3% to £7.3m despite a 6.9% revenue decline) and an exceptional net asset growth trajectory (£7m to £33.9m over eight years). However, it presents with two significant symptoms requiring treatment: dangerously thin cash reserves (£0.5m on £64m turnover) and an increasingly inventory-heavy balance sheet (76.5% of assets in stock, with stock turn deteriorating from 209 to 262 days). The business must urgently address its liquidity position and inventory velocity while developing a strategic response to the long-term diesel-to-electric transition that threatens its domestic market.
