HYDROCK HOLDINGS LIMITED

• ⚠

  Material uncertainty over going concern

  On 1 January 2026, all the companies within this Group will transfer the future trade, assets and liabilities, with the exception of certain balances with less than 12 months left to Stantec UK Limited. The companies within this Group will then wind down their activities during the 2026 financial year and will cease to trade. The directors have a reasonable expectation that the companies within this Group will be liquidated and cease to continue in operational existence within the period of at least twelve months from the date of approval of these financial statements. However, the date of liquidation has not yet been decided. As a result, the directors have prepared the financial statements on a basis other than going concern, but no adjustments were necessary to the amounts at which the remaining net assets are included in these financial statements.

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

Margins divide P&L lines by turnover. Gearing is liabilities over total assets. Current ratio is current assets over creditors falling due within one year. Interest cover is operating profit over absolute finance costs. Sector-distribution context coming next.

Stantec is a global leader in sustainable design and engineering with over 30,000 employees worldwide.”

Once the transfer is finalised, the Hydrock entities are expected to cease trading.”
