- Going concern
- Affirmed
“The Group is a significant sub-group within Hartree. In February 2015, the Hartree Group entered into a borrowing base revolving credit facility with a bank group ("ABL Bank Facility"). In September 2024, Hartree upsized the facility to $4,100 million and extended the maturity of the committed tranche ($2,050 million) of the ABL Bank Facility to 4 September 2027 (the uncommitted tranche of $2,050 million matures on 4 September 2026). The assets of the Hartree Group have been pledged to the bank syndicate as security. Accordingly, the Group is dependent upon the Hartree Group maintaining compliance with the terms and covenant tests of the ABL Bank Facility in order to avoid a call upon the pledge provided by the Group to the bank syndicate. Based on the above analysis, the going concern basis of preparation has been considered appropriate, as the directors believe that the Group will be in operation for the going concern period ending 30 April 2026.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
