Ilika PLC, down 21% at 75.00 pence, 12-month range 74.66p-220.48p. Trading in the financial year that ended April 30 was in line with management expectations but issues warning for 2023. Revenue in recent year estimated to be down to GBP500,000 from GBP2.3 million the year prior. Expects to report annual earnings before interest, taxes, depreciation, and amortization loss of GBP7.0 million versus earnings of GBP2.3 million in financial 2021. Looking ahead, notes its Stereax manufacturing site for miniature solid-state batteries is "taking longer than previously anticipated" to produce product batches that meet specification. Adds: "The shift in the weighting of customer demand towards medical device applications combined with the expectation of optimisation cycles continuing into H2 FY23, means the company now expects commercial sales to commence at the end of that period, later than originally anticipated."
