Nanosonics (ASX:NAN) said it expects to report profit before tax for the fiscal first half ended December 2024 of about AU$10.9 million, compared with AU$4.9 million in the prior corresponding period, according to a Thursday Australian bourse filing.

It also expects total revenue for the fiscal first half to be about AU$93.6 million, up 18% from AU$79.6 million in the same period a year prior. Its operating expenses are anticipated to be about AU$66.7 million, up 10% from the prior-year period.

The firm said its gross margin for the period is expected to be about 78.5% from 79.7% year on year.

It expects revenue, gross margin, and operating expenses in the current fiscal year to be on top of the guidance range. It had said it expected fiscal year growth in revenue of 8% to 12%, and in operating expenses of 6% to 10%, while its gross margin was expected to be between 77% to 79%, in an earlier filing.

The revenue growth is attributable to 20% growth in its consumables and service annuity revenue streams, according to its chief executive, Michael Kavanagh.
