NOTES TO THE ACCOUNTS
FOR THE YEAR ENDED 31 MARCH 2025

1.


General information

MitoRx Therapeutics Limited is a private company, limited by share capital and incorporated in England and Wales.

The Company's registered office is 9400 Garsington Road, Oxford Business Park, Oxford, OX4 2HN.  The Company's principal place of business is Building 383, Harwell Oxford, Didcot, Oxfordshire OX11 0RD, United Kingdom. 

The principal activity of the Company is research and experimental development on biotechnology & other business support services. 

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with FRS 102 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland' and the requirements of the Companies Act 2006. 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 following principal accounting policies have been applied:

 
2.2

Going concern

The directors note that the Company is loss-making and is continuing its product development. Significant levels of funding has been raised in the year. The directors note that they can manage the timing of cash outflows in relation to future development expenditure. Based on the Company's current cash reserves, the management of the timing of development expenditure and future funding plans, the directors have concluded that the Company has adequate resources to continue in operational existence and to meet its financial obligations as they fall due for at least 12 months from the date of signing these financial statements. Accordingly, the directors continue to adopt the going concern basis in preparing the financial statements.

 
2.3

Foreign currency translation

Transactions in currencies other than the functional currency (foreign currency) are initially recorded at the exchange rate prevailing on the date of the transaction. 

Monetary assets and liabilities denominated in foreign currencies are translated at the rate of exchange ruling at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies are translated at the rate ruling at the date of the transaction, or, if the asset or liability is measured at fair value, the rate when that fair value was determined.

All translation differences are taken to profit or loss, except to the extent that they relate to gains or losses on non-monetary items recognised in other comprehensive income, when the related translation gain or loss is also recognised in other comprehensive income. 

 
2.4

Interest income

Interest income is recognised in profit or loss using the effective interest method.

NOTES TO THE ACCOUNTS
FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.5

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

 
2.6

Share-based payments

Equity-settled share-based payments are measured at fair value at the date of grant by reference to the fair value of the equity instruments granted using the Black-Scholes model. The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, based on the estimate of shares that will eventually vest. A corresponding adjustment is made to equity. 
 

 
2.7

Taxation

Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the Company operates and generates income.

 
2.8

Intangible assets

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

 
2.9

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

NOTES TO THE ACCOUNTS
FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)


2.9
Tangible fixed assets (continued)

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method.

Depreciation is provided on the following basis:

Plant and machinery
-
33%
Office equipment
-
33%
Computer equipment
-
33%

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

 
2.10

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
2.11

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

 
2.12

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
2.13

Financial instruments

The Company only enters into basic financial instrument transactions that result in the recognition of
financial assets and liabilities like trade and other debtors and creditors, loans from banks and other
third parties, loans to related parties and investments in ordinary shares.


3.


Employees

The average monthly number of employees, including directors, during the year was 9 (2024 - 9).
