Post period end trading update

Haydale, (AIM: HAYD), the global advanced materials group, announces a trading update for the year ended 30 June 2022  (the "Year" or "FY2022").

The Group now anticipates, subject to audit, announcing revenues for the Year ahead of prior expectations at approximately £2.90 million with gross profit of approximately £1.74 million and LBITDA marginally behind prior guidance at £3.35 million.  Capital Expenditure in the Year was £1.00 million and Year end cash stood at £1.19 million.

As previously indicated, the commercial momentum from the second half of the Year is expected to accelerate into the new financial year with both an increased customer and product portfolio contributing to this.  Against this increase, the annualised impact of the investment in sales, marketing, quality and production resource during FY2022 alongside the inflationary cost pressures we are seeing at our operating units will partly offset the expected uplift in revenue at the LBITDA level.   We anticipate that the current year LBITDA will be smaller than FY2022 but not to the extent previously expected.

Notwithstanding this, with the significant increase that the HT1400 has delivered to the Group's functionalisation capacity combined with the investment made in human capital the Board remains confident that it has the fundamental building blocks in place to take advantage of the commercial traction it is seeing.   The Board remain confident in the medium and longer term prospects for the Group.
