Tethys Delta Limited is a private company limited by shares incorporated in England and Wales. The registered office is Deep Campus, A48, Tidenham, Chepstow, United Kingdom, NP16 7LQ.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime. The disclosure requirements of section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

A connected beneficiary has offered financial support to the company, for a period of at least 12 months from the date of approval of these financial statements, should it be required to meet liabilities as they fall due. Therefore, at the time of approving the financial statements, the directortrue has a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Accordingly, the financial statements have been prepared on a going concern basis.

Turnover is recognised at the fair value of the consideration received or receivable for the use of its submersibles straight line over the rental period. It is shown net of VAT and other sales related taxes.

Tangible fixed assets are initially measured at cost and subsequently measured at cost, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to profit or loss.

At each reporting period end date, the company reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any)

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

The company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the company's balance sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method. Financial assets classified as receivable within one year are not amortised.

Financial liabilities are classified according to the substance of the contractual arrangements entered into.

Basic financial liabilities, including creditors and loans from fellow group companies are initially recognised at transaction price. Financial liabilities classified as payable within one year are not amortised.

Debt instruments are subsequently carried at amortised cost, using the effective interest rate method.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

In the application of the company’s accounting policies, the director is required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The following judgements have had the most significant effect on amounts recognised in the financial statements.

The director has applied significant judgement with regard to the value of the tangible fixed assets at 31 December 2025.

The company owns submersibles which are highly specialised in nature and integral to the company's operations. The submersibles were purchased from a third party and are held at cost less depreciation as presented in note 6.

The director has considered the carrying value of the assets at 31 December 2025. They have determined, based on a review of the submersible market, that the recoverable amount (being fair value less cost to sell) is in excess of the net book value at 31 December 2025. The primary judgement applied is in benchmarking used models against the RRP of new models. They are comfortable with this benchmarking as the long-life components of the submersibles are routinely recertified.

The director has applied significant judgement in determining the depreciation policy applied to the submersibles.

Due to the highly specialised nature of these assets, the director has exercised judgement in estimating the assets' useful economic lives. The depreciation policy applied is considered to best reflect the expected consumption of economic benefits from the assets.

The company did not have any employees in the current or the prior financial year.

Included within amounts owed to group undertakings is a loan principal of £3,645,264 (2024: £3,645,264) plus accrued interest of £300,830 (2024: £227,925) payable to the parent company. The loan is repayable on demand and interest of 2% is charged on the loan.

The immediate and ultimate parent company is Chaotic Good Holdings Inc (formerly DEEP Ventures Inc), a company registered in Liechtenstein whose registered office is c/o Schreiber & Zindel Treuhand-Anstalt, Kirchstrasse 39, 9490 Vaduz, Liechtenstein.

The parent company does not prepare consolidated accounts.
