Nov 18 (Reuters) - Austrian light and sensor maker ams OSRAM AMS2.VI forecast fourth-quarter revenue below market estimates on Tuesday, signalling no recovery in the automotive, industrial and personal electronics markets, where its main clients are from.
Its Switzerland-listed shares fell 15% by 1020 GMT to the bottom of the Swiss mid-cap index .SMIM.
The world's largest maker of light sensors said fourth-quarter revenue was expected in a range of 790 million to 890 million euros ($917 million to $1.03 billion), which would mean a fall of 10% at the lowest and a rise of 1% at the high end.
Analysts polled by LSEG were expecting revenue to grow 1.9% from a year earlier to 899 million euros on average in the final quarter of 2025.
"Fourth-quarter sales outlook missed expectation and was a bit disappointing signalling basically no recovery in end demand," analyst Veysel Taze from Metzler said.
Most semiconductor companies exposed to weak end-markets, such as Infineon IFXGn.DE and STMicroelectronics STMPA.PA, have previously said they expected an uptick in demand in the second half of 2025.
Ams OSRAM also said in February it expected the second half to be meaningfully stronger than the first, assuming some market normalisation.
The group's management continues to stabilize the business, but it needs recovery in its main markets to remove a debt burden, Taze said.
In the third quarter, ams OSRAM's debt increased to 1.58 billion euros, from 1.57 billion three months earlier.
Third-quarter sales were 853 million euros, while adjusted earnings before interest, taxes, depreciation and amortization stood at 166 million euros. That was slightly below LSEG analyst poll estimates for revenue and in line with them for EBITDA.
Ams OSRAM reaffirmed its full-year guidance, contingent on receiving cash inflows from Austrian government subsidies under the European Chips Act later this year.
