NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 28 FEBRUARY 2026

1.


GENERAL INFORMATION

Cosyne Therapeutics Limited is a private company limited by shares and incorporated in England and Wales. Its registered office is 2 Sheraton Street, WeWork Medius House, London, England, W1F 8BH.

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 Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and 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

As at the year end, the Company had net liabilities of £472,854 (2025 - net assets of £2,114,577). The financial statements have been prepared on the going concern basis which assumes that the Company will continue as a going concern for the foreseeable future. The trading losses reported to date are consistent with the Company's business plan as it progresses its research and development activities.

Given the investment received, together with the development progress achieved, the directors have a reasonable expectation that the Company will be able to meet its liabilities as they fall due for the foreseeable future and therefore continue to adopt the going concern basis.

 
2.3

FOREIGN CURRENCY TRANSLATION

Functional and presentation currency

The Company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Profit and Loss Account within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

FOR THE YEAR ENDED 28 FEBRUARY 2026

2.ACCOUNTING POLICIES (CONTINUED)

 
2.4

TURNOVER

Turnover is recognised to the extent that it is probable that the economic benefits will flow to the Company and the turnover can be reliably measured. Turnover is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before turnover is recognised:

Rendering of services

Turnover from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
the amount of turnover can be measured reliably;
it is probable that the Company will receive the consideration due under the contract;
the stage of completion of the contract at the end of the reporting period can be measured reliably; and
the costs incurred and the costs to complete the contract can be measured reliably.

 
2.5

OPERATING LEASES: THE COMPANY AS LESSEE

Rentals paid under operating leases are charged to profit or loss on a straight-line basis over the lease term.

 
2.6

RESEARCH AND DEVELOPMENT

In the research phase of an internal project it is not possible to demonstrate that the project will generate future economic benefits and hence all expenditure on research shall be recognised as an expense when it is incurred. Intangible assets are recognised from the development phase of a project if and only if certain specific criteria are met in order to demonstrate the asset will generate probable future economic benefits and that its cost can be reliably measured. The capitalised development costs are subsequently amortised on a straight-line basis over 10 years.

If it is not possible to distinguish between the research phase and the development phase of an internal project, the expenditure is treated as if it were all incurred in the research phase only.

 
2.7

INTEREST INCOME

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

 
2.8

FINANCE COSTS

Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 28 FEBRUARY 2026

2.ACCOUNTING POLICIES (CONTINUED)

 
2.9

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 other creditors as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

 
2.10

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.


 
2.11

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.

 The estimated useful lives range as follows:

Patents
-
10
years
Domain
-
10
years

 
2.12

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 FINANCIAL STATEMENTS
FOR THE YEAR ENDED 28 FEBRUARY 2026

2.ACCOUNTING POLICIES (CONTINUED)


2.12
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:

Office equipment
-
12-36 months
Computer equipment
-
12-36 months

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.

 
2.13

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.

 
2.14

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.

 
2.15

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.


3.


EMPLOYEES

The average monthly number of employees, including directors, during the year was 18 (2025 - 21).
