9.30am: Revenue warnings hit the shares of Goodwin and Plant Health Care 

The share price of steel castings specialist Goodwin PLC (LON:GDWN) showed a few cracks after it flagged a slowdown for the Refractory Engineering Division.

The shares slumped 19% to 2,860p after the company revealed there had been an unforeseen decrease in demand for the consumer-orientated jewellery products for which supplies the casting powder, which the company attributed to the USA and China trade war.

Profit before tax in the six months to the end of October eased to £7.41mln from £7.80mln the year before despite an increase in revenue to £70.09mln from £67.55mln.

Plant Health Care PLC’s (LON:PHC) shares wilted to 7p from 8.55p overnight as it warned full-year revenue would be below expectations.

The bioproducts company’s revenue is expected to clock in at around US$6.5mln, with the shortfall versus market expectations attributed to delays in the delivery of its harpin-based yield stimulant, H2Copla, in Brazil and the postponement of around US$1mln in US sales of its Harpin product for corn seed by its distributor, which is suffering from working capital pressures.

“In 2019, as in 2018, last-minute customer and logistical issues will result in revenue falling short of expectation; however, the delay in sales is principally a matter of phasing,” said Chris Richards, the chief executive officer of Plant Health.
