NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 JUNE 2025

1.


General information

ARCH Venture Management UK Limited. (the "Company") is a private company limited by shares and is incorporated,domiciled and registered in England and Wales (Registered number: 14587638). The address of its registered office is C/O Andersen LLP, 20 Gracechurch Street,11th Floor, London, United Kingdom, EC3V 0BG.

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 Section 1A of Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006.

The financial statements are presented in Sterling (£), which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The following principal accounting policies have been applied:

  
2.2

Going concern

The director has determined that preparing the financial statements on the going concern basis is appropriate due to the continued financial support of the ultimate parent company, ARCH Venture Management LLC. The director's going concern assessment covers the period to 31 December 2027 and confirmation has been received that ARCH Venture Management LLC will support the Company until this date, so long as the Company remains a subsidiary of ARCH Venture Management LLC.
The Company's ability to meet its future liabilities is therefore dependent on the financial performance, position and liquidity of the Group as a whole. At a ARCH Venture Management LLC level, considerations included potential risks and uncertainties in the business, credit, market and liquidity risks. Stress testing has been carried out to ensure ARCH Venture Management LLC has sufficient cash resources to continue in operation for the period to 31 December 2027. This stress testing modelled a scenario with materially reduced levels of cash receipts over the next 12 months. Based on these considerations, together with available market information and the director's knowledge and experience of the Company, the director continues to adopt the going concern basis in preparing the financial statements for the period ended 30 June 2025.

 
2.3

Revenue

Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue 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 revenue is recognised:

Revenue is recognised on a cost plus 8% basis, in line with the intercompany service agreement with the parent company. Intercompany revenue is recognised when all of the following conditions are satisfied :
- the amount of revenue can be measured reliably;
- it is probable that the Company will receive the consideration due under the intercompany service
  agreement; and
- the costs incurred under the intercompany service agreement can be measured reliably.

2.Accounting policies (continued)

 
2.4

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.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

 
2.5

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.

 
2.6

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.

 
2.7

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.

  
2.8

Provisions for liabilities

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made.
Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties.
Increases in provisions are generally charged as an expense to profit or loss.

  
2.9

Share capital

Ordinary shares are classified as equity.
