Higher costs and impairment hurt Symphony Environmental Technologies

Symphony Environmental Technologies PLC on Tuesday said performance has materially improved in the current year after one-off costs and an impairment charge hit the bottom line in 2025.

The Hertfordshire, England-based biodegradable plastic technology developer reported a pretax loss of £2.5 million in 2025, stretched from £1.3 million the year prior.

Losses included £468,000 impairment of development costs compared to nil the year before, and higher administrative costs of £4.3 million, up from £3.8 million, including one off strategic costs of £500,000.

Basic and diluted losses per share totalled 1.08 pence compared to 0.63p a year prior.

Revenue declined 13% to £5.7 million from £6.6 million.

In response, shares in the firm fell 9.7% to 8.13 pence each in London on Tuesday.

Symphony Environmental Technologies said financial performance has materially improved in 2026 with the group achieving a net profit for the first five months versus a loss in the comparative period last year, supported by a 10% increase in revenues, stronger gross margins and improved operating leverage.

‘While further progress is required, the combination of an improved operating model, strengthened margins, enhanced regulatory positioning and a maturing technology pipeline places the group on a materially stronger footing than in prior periods,’ the company said.
