NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1.
Corporate information

GH Research PLC (the “Company”) was incorporated on March 29, 2021. The registered office of the Company is located at Joshua Dawson House, Dawson Street, Dublin 2, Ireland.

The Company and its subsidiary, GH Research Ireland Limited, (together the “Group” or “GH Research”) are a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders. Its initial focus is on developing the novel and proprietary mebufotenin (5-methoxy-N,N-dimethyltryptamine, or 5-MeO-DMT) therapies for the treatment of patients with Treatment Resistant Depression, or TRD. Its portfolio currently includes GH001, a proprietary inhalable mebufotenin product candidate, GH002, a proprietary intravenous mebufotenin product candidate, and GH003, a proprietary intranasal mebufotenin product candidate.

These unaudited condensed consolidated interim financial statements were presented to the board of directors and approved by them for issue on August 23, 2023.

2.
Basis of preparation, significant judgments, and accounting policies

Basis of preparation

Compliance with International Financial Reporting Standards
The unaudited condensed consolidated interim financial statements for the three and six months ended June 30, 2023 have been prepared in accordance with IAS 34 “Interim Financial Reporting”. The unaudited condensed consolidated interim financial statements do not include all of the information required for full annual financial statements and should be read in conjunction with the consolidated financial statements for the year ended December 31, 2022 which were prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). These unaudited condensed consolidated interim financial statements are presented in U.S. dollar (“USD” or “$”), which is the Company’s functional currency and the Group’s presentation currency.

The financial information presented in this interim report does not represent full statutory accounts as defined by the Companies Act 2014. The statutory accounts of GH Research PLC for the year ended December 31, 2022, are expected to be filed with the Companies Registration Office by November 26, 2023.

New and amended IFRS standards
There are no new IFRS standards, amendments to standards or interpretations that are mandatory for the financial year beginning on January 1, 2023, that are relevant to the Group and that have had any material impact in the interim period. New standards, amendments to standards and interpretations that are not yet effective, have been deemed by the Group as currently not relevant and are not listed here.
 
Going concern basis
GH Research is a clinical-stage biopharmaceutical company developing innovative therapeutics. The Group is exposed to all risks inherent in establishing and developing its business, including the substantial uncertainty that current projects will succeed. Research and development expenses have been incurred from the start of the Group’s activities, generating negative cash flows from operating activities since formation.
 
Since its incorporation, the Group has funded its growth through capital increases. The Group has no bank loans or other debt outstanding, except lease liabilities, as of June 30, 2023. As a result, the Group is not exposed to liquidity risk through requests for early repayment of loans.
 
As of June 30, 2023, the Group’s cash and cash equivalents amounted to $96.9 million (December 31, 2022: $166.0 million). The Group also held marketable securities of $86.5 million and other financial assets of $54.7 million as of June 30, 2023, (December 31, 2022: marketable securities of $85.7 million and other financial assets of $nil). The Group’s marketable securities are quoted in active markets and are an additional source of liquidity.

GH RESEARCH PLC
 
NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (continued)
The Board of Directors believes that the Group has sufficient financial resources available to cover its planned cash outflows for at least the next twelve months from the date of issuance of these unaudited condensed consolidated interim financial statements. The Group, therefore, continues to adopt the going concern basis in preparing its unaudited condensed consolidated interim financial statements.

Use of estimates and judgments
The preparation of the unaudited condensed consolidated interim financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Actual results may differ from these estimates.

In preparing these unaudited condensed consolidated interim financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty are consistent with those that applied in the preparation of the consolidated financial statements for the year ended December 31, 2022.

Accounting policies
The accounting policies, presentation and methods of computation followed in the unaudited condensed consolidated interim financial statements are consistent with those applied in the Group’s most recent annual financial statements and have been applied consistently to all periods presented in the unaudited condensed consolidated interim financial statements except for the amendments and new accounting policies set out below.

Other financial assets
Other financial assets represent money market funds with a weighted average maturity of more than 90 days and are carried at fair value through profit or loss as the cash flows from these funds do not represent solely payments of principal and interest.

Leases and right-of-use assets
The Group recognizes a right-of-use (“ROU”) asset and a corresponding lease liability for all arrangements in which it is a lessee, except for leases with a term of 12 months or less (short-term leases) and low-value leases. Under IFRS 16 the Group recognizes a ROU asset and a lease liability at the lease commencement date at the present value of the future lease payments, discounted at the Group’s incremental borrowing rate. The ROU asset is subsequently depreciated using the straight-line method over the lease term within depreciation expenses and an interest expense on lease liabilities is recognized within finance expense in the Group’s unaudited condensed consolidated interim income statement. The interest expense is calculated based on the incremental borrowing rate of the Group.

For short-term or low value leases, the Group recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease.

Current and deferred income tax
The interim income tax expense is calculated based on the Company’s estimate of the weighted average effective annual income tax rate expected for the full year. The current and deferred income tax charge was $nil for the three and six months ended June 30, 2023 and 2022, which is in line with the Company’s estimate for the full year. No deferred tax assets have been recognized as there is no certainty that sufficient taxable profits will be generated within the required timeframe to be able to utilize these tax loss carry-forwards in full.

Loss and earnings per share
Basic loss and earnings per share is calculated by dividing the net loss or profit attributable to shareholders by the weighted average number of shares in issue during the period. Diluted earnings per share is calculated using the treasury method which adjusts for the potential dilutive effect of other share options if such share options were exercised and are not anti-dilutive.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (continued)
Segment reporting
Management considers the Group to have only a single segment: Research and Development (“R&D”). This is consistent with the way that information is reported internally within the Group for the purpose of allocating resources and assessing performance.

2 Included in employee expenses is share based compensation expense of $0.2 million and $0.4 million for the three and six months ended June 30, 2023, respectively, relating to employees in the general and administrative department (three and six months ended June 30, 2022, $0.2 million and $0.4 million, respectively).
 
Foreign exchange gain
 
Foreign exchange gain of $36 thousand for the three months ended June 30, 2023 (3 months ended June 30, 2022, gain of $7.1 million), and foreign exchange loss of $1.6 million for the six months ended June 30, 2023 (6 months ended June 30, 2022, gain of $9.3 million) consists primarily of gains and losses related to the translation of the U.S. dollar cash and other financial assets balance into euro in the accounts of the Company’s subsidiary, GH Research Ireland Limited, whose functional currency is euro as explained in the Group’s consolidated financial statements for the year ended December 31, 2022.
 
At June 30, 2023, if the U.S. dollar had weakened/strengthened by 10% against the euro with all other variables held constant, the loss before tax for the six months ended June 30, 2023, would have been $8.1 million higher/lower, mainly related to the translation of cash and other financial assets held in U.S. dollar in the Company’s subsidiary, GH Research Ireland Limited.

Share based compensation
 
Share Options
In June 2021, the Company adopted a share option plan referred to herein as the Share Option Plan under which grants of options are made to eligible participants. The Company has reserved 1,202,734 ordinary shares for future issuance under the Share Option Plan, which include ordinary shares pursuant to share-based equity awards issued to date. As of June 30, 2023, the Company has 548,817 ordinary shares available for the future issuance of share-based equity awards.
 
Under the Share Option Plan, the options may be settled only in ordinary shares of the Company. Therefore, the grants of share options under the Share Option Plan have been accounted for as equity-settled under IFRS 2. As such, the Company records a charge for the vested portion of award grants and for partially earned but non-vested portions of award grants.
 
During the three and six months ended June 30, 2023, the Company granted the option to purchase 248,500 and 270,820 ordinary shares, respectively, to employees which were in line with the general terms of the Share Option Plan. During the three and six months ended June 30, 2023, 78,499 share options were forfeited.

The award life is based on the time interval between the date of grant and the date during the life of the share option after which, when making the grant, the Company expected on average that participants would exercise their options.
 
As of June 30, 2023, Other Reserves within equity includes $3.0 million (December 31, 2022: $2.0 million) relating to the Group’s Share Option Plan.

For the three months ended June 30, 2023, and the six months ended June 30, 2023, and 2022, basic and diluted loss per share are calculated on the weighted average number of shares issued and outstanding and exclude shares to be issued under the Share Option Plan, as the effect of including those shares would be anti-dilutive.
 
For the three months ended June 30, 2022, basic and diluted earnings per share are calculated on the weighted average number of shares issued and outstanding and, in the case of diluted earnings per share, exclude shares to be issued under the Share Option Plan. The shares to be issued under the Share Option Plan have been excluded as the total of the exercise price and the average unrecognized compensation for the period of the options was greater than the average per share closing price during the three months ended June 30, 2022, and as such are anti-dilutive.
