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 September 3, 2024.

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

Basis of preparation

Compliance with IFRS Accounting Standards

The unaudited condensed consolidated interim financial statements for the three and six months ended June 30, 2024 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, 2023, which were prepared in accordance with IFRS Accounting Standards as adopted 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, 2023, are expected to be filed with the Companies Registration Office by November 26, 2024.

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, 2024, that are relevant to the Group and that have had any material impact in the interim period. The review of the impact of new standards on the Group’s financial statements which are not yet effective and which have not been early adopted by the Group is ongoing. This includes the recently issued IFRS 18 “Presentation and Disclosure in Financial Statements”. There are no other amendments to standards and interpretations that are not yet effective which have been deemed relevant to the Group.

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, 2024. As a result, the Group is not exposed to liquidity risk through requests for early repayment of loans.

As of June 30, 2024, the Group’s cash and cash equivalents amounted to $87.1 million (December 31, 2023: $78.4 million). The Group also held marketable securities of $75.4 million and other financial assets of $42.0 million as of June 30, 2024 (December 31, 2023: marketable securities of $88.7 million and other financial assets of $55.6 million). The marketable securities held by the Group are quoted in active markets and are an additional source of liquidity. 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.

GH RESEARCH PLC

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (continued)

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, 2023.

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.

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, 2024 and 2023, 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.

Research and development tax credits

As explained in the Group’s consolidated financial statements for the year ended December 31, 2023, an amount of $1.3 million had remained unrecognized with respect to research and development tax credit claims for the year ended December 31, 2022 and 2021. In the six months ended June 30, 2024, an amount of $0.8 million has been received by the Group which has been recognized as a deduction from research and development expenses under the Group’s relevant accounting policy. At June 30, 2024, a balance of $0.5 million remains unrecognized as it has been concluded that reasonable assurance has not been achieved. Judgment was applied in this determination.

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.

Total operating expenses		13,219		9,925		24,747		20,344

¹Included in employee expenses is a share based compensation credit of $0.1 million for the three months ended June 30, 2024, and a share based compensation expense of $0.1 million for the six months ended 30 June 2024, relating to employees in the research and development department (three and six months ended June 30, 2023, expense of $0.2 million and $0.6 million, respectively).

² Included in employee expenses is share based compensation credit of $8 thousand for the three months ended June 30, 2024, and a share based compensation expense of $0.1 million for the six months ended 30 June 2024, relating to employees in the general and administrative department (three and six months ended June 30, 2023, $0.2 million and $0.4 million, respectively).

³Includes termination expenses incurred in the period.

Foreign exchange gain/loss

Foreign exchange gain of $0.5 million for the three months ended June 30, 2024 (foreign exchange gain of $36 thousand for the three months ended June 30, 2023), and foreign exchange gain of $1.8 million for the six months ended June 30, 2024 (foreign exchange loss of $1.6 million for the six months ended June 30,2023) 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, 2023.

At June 30, 2024, 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, 2024, would have been $4.6 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. This would be offset by an equivalent amount within Other Comprehensive Income.

11.	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, 2024, the Company has 453,788 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, 2024, the Company granted the option to purchase 53,500 and 121,500 ordinary shares, respectively, to employees which were in line with the general terms of the Share Option Plan. All share options granted to employees during the three and six months ended June 30, 2024, had a contractual term (expiration) of eight years from the grant date with an exercise price at the closing market price on the day prior to the grant.

During the three and six months ended June 30, 2024, the Company granted the option to purchase 16,524 ordinary shares to members of the board of directors relating to the 2023/2024 period of service which vested on the date of grant and are subject to a two year service condition. These share options have a contractual term (expiration) of seven years from the grant date with an exercise price of $0.025 per share.

The following table summarizes the share option awards outstanding as of June 30, 2024:

	Average exercise price per share in USD		Number of awards			Weighted average remaining life in years

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (continued)

The fair values of the options granted during the three and six months ended June 30, 2024, were determined on the date of the grant using the following assumptions:

	Three months ended June 30, 2024		Six months ended June 30, 2024
Share price, in USD		11.80 - 14.81		5.80 - 14.81
Strike price, in USD – employees (weighted average)		13.63		9.90
Strike price, in USD – non-executive directors		0.03		0.03
Expected volatility		85% - 91%		85% - 91%
Award life (weighted average)		5.65		5.82
Expected dividends		-		-
Risk-free interest rate		4.26% - 4.52%		3.82% - 4.52%

The expected volatility was based on selected volatility determined by median values observed among other comparable public companies.

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, 2024, Other Reserves within equity includes $3.9 million (December 31, 2023: $4.2 million) relating to the Group’s Share Option Plan. Balances which relate to forfeited awards which had previously vested are transferred from Other Reserves to Accumulated Deficit. The amount of expense for all awards recognized for services received during the three months ended June 30, 2024, was a credit of $0.1 million (three months ended June 30, 2023: expense of $0.4 million) and for the six months ended June 30, 2024, was an expense of $0.1 million (six months ended June 30, 2023: expense of $1.0 million). The reduction in expense is primarily due to leavers in the period.

12.	Related party disclosures

Other than those transactions reported in Note 11, “Share-based compensation”, there have been no other transactions in the three or six months ended June 30, 2024 and ended June 30, 2023, with related parties that had a material effect on the financial position or performance of the Group.

Overview

We are a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders. Our initial focus is on developing our 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. Mebufotenin was selected as the International Nonproprietary Name (INN) for 5-MeO-DMT by the World Health Organization (WHO) Expert Advisory Panel on the International Pharmacopoeia and Pharmaceutical Preparations.

Our portfolio currently includes GH001, our proprietary inhalable mebufotenin product candidate, GH002, our proprietary intravenous mebufotenin product candidate, and GH003, our proprietary intranasal mebufotenin product candidate. While GH001 is currently delivered via a vaporization device produced by a third party, we are developing a proprietary aerosol delivery device. We have completed two Phase 1 healthy volunteer clinical trials for GH001 (GH001-HV-101 and GH001-HV-103), in which administration of GH001 via inhalation was observed to be well tolerated at the investigated single dose levels and in an individualized dosing regimen, or IDR, with intra-subject dose escalation within a single day. We have also completed a Phase 1/2 clinical trial in patients with TRD (GH001-TRD-102). Based on observed clinical activity in the Phase 1 part of the clinical trial, we believe that administration of a single dose of GH001 has the potential to induce ultra-rapid remissions as measured by the Montgomery-Åsberg Depression Rating Scale, or MADRS, in certain patients, driven by the ultra-rapid onset of psychoactive effects (commonly within seconds) and an intense and short-lived (commonly five to 30 minutes) psychoactive experience. Based on observed clinical activity in the Phase 2 part of the trial, we believe that administration of GH001 in an IDR with intra-subject dose escalation within a single day can further increase the MADRS remission rate as compared to a single dose of GH001.

We have incurred losses since inception, including losses of $18.0 million for the six months ended June 30, 2024, and losses of $35.6 million and $22.5 million for the years ended December 31, 2023 and 2022, respectively. As of June 30, 2024, we had an accumulated deficit of $85.6 million. We expect to incur significant expenses and operating losses for the foreseeable future as we expand our research and development activities. In addition, our losses from operations may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials, our expenditures on other research and development activities and based on foreign currency translation differences. We anticipate that our expenses will increase significantly in connection with our ongoing activities, if and as we:

•

continue to develop and conduct clinical trials, including in expanded geographies such as the United States, for GH001, our inhalable mebufotenin product candidate, GH002, our intravenous mebufotenin product candidate, and GH003, our intranasal mebufotenin product candidate for our initial indications and additional indications;

•

continue both the technical development and expansion of our external manufacturing capabilities for our current product candidates GH001, GH002 and GH003 and of the medical devices required to deliver these product candidates, such as our proprietary aerosol delivery device for GH001;

•

initiate and continue research and development, including nonclinical, clinical, and discovery efforts for any future product candidates;

•

seek to identify additional product candidates;

•

seek regulatory approvals for our product candidates GH001, GH002 and GH003, including the medical devices required to deliver these product candidates, such as our proprietary aerosol delivery device, or any other product candidates that successfully complete clinical development;

•

progress any nonclinical programs and any other work that may be required to lift the clinical hold on the study we proposed in our IND for GH001;

•

add operational, financial and management information systems and personnel, including personnel to support our product candidate and device development and help us comply with our obligations as a public company;

•

hire and retain additional personnel, such as clinical, quality control, scientific, commercial, sales, marketing and administrative personnel;

•

continue to prepare, file, prosecute, maintain, protect and enforce our intellectual property rights and claims;

•

establish sales, marketing, distribution, manufacturing, supply chain and other commercial infrastructure in the future to commercialize various products for which we may obtain regulatory approval;

•

comply with ongoing regulatory requirements for products approved for commercial sale, if ever;

•

acquire or in-license other product candidates, medical devices to deliver our product candidates, and other technologies; and

•

incur increased costs as a result of operating as a public company.

In addition, as we progress toward marketing approval for any of our product candidates, we also expect to incur significant commercialization expenses related to product manufacturing, marketing, sales, and distribution.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. We cannot be certain that additional funding will be available on acceptable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back, or discontinue the development and commercialization of one or more of our product candidates or other research and development initiatives, which could have a material adverse effect on our business, results of operations, and financial condition. We will need to generate significant revenue to achieve profitability, and we may never do so.

We are subject to a number of risks comparable to those of other similar companies, including dependence on key individuals; the need to develop product candidates with the required safety and efficacy profile and which support regulatory approval and are commercially viable; competition from other companies, many of which are larger and better capitalized; and the need to obtain adequate additional financing to fund the development of our product candidates.

Business Updates

We announced today, in a separate press release, the promotion of Dr. Velichka “Villy” Valcheva, MD, MSc. to Chief Executive Officer of the Company. Dr. Valcheva succeeds PD Dr. med. Theis Terwey, co-founder of GH Research.

GH001 in Patients with TRD

GH001, our proprietary inhaled mebufotenin (5-MeO-DMT) product candidate, is currently being investigated in a multi-center, randomized, double-blind, placebo-controlled Phase 2b trial in approximately 80 patients with treatment-resistant depression (TRD) (GH001-TRD-201) with approximately 20 sites across seven European countries.

We continue to recruit according to plan, supporting the expected completion of the double-blind phase of this trial in the third quarter of 2024 and of the 6-month open-label extension in the first quarter of 2025. Top-line data for the double-blind phase is expected to be available in the fourth quarter of 2024 or the first quarter of 2025.

In this trial, GH001 is administered using a commercially available inhalation device. Consistent with previously completed trials, GH001 is administered on a single initial dosing day, without additional mandated visits for psychotherapy or psychological support before or after dosing.

GH001 in Patients with PPD and BDII

GH001 is being investigated in a proof-of-concept clinical trial in patients with postpartum depression (PPD) (GH001-PPD-203). We expect GH001-PPD-203 completion in the fourth quarter of 2024.

GH001 is also being investigated in a proof-of-concept clinical trial in bipolar II disorder in patients with a current depressive episode (BDII) (GH001-BD-202).

GH001 Administered with Proprietary Aerosol Delivery Device

We previously announced our submission of a clinical trial application for a Phase 1 clinical pharmacology trial in Europe to evaluate our proprietary aerosol delivery device for administration of GH001 in healthy volunteers (GH001-HV-106). This trial is designed to support bridging to the clinical data generated with the commercial device we have used, and are using, in our clinical trials to date. This trial has recently received full regulatory and ethical approval in the United Kingdom and is now recruiting.

Update on IND for GH001

As previously announced, our Investigational New Drug Application (IND) for GH001 administered using our proprietary aerosol delivery device was placed on clinical hold by the U.S. Food and Drug Administration (FDA), with the FDA requesting that we provide additional information, including (i) an inhalation toxicology study in a non-rodent species and an additional inhalation toxicology study in rats, (ii) additional device design verification information and (iii) updates to our investigator brochure, to resolve the hold.

We requested a meeting with the FDA to discuss specific aspects of their device feedback and this meeting was executed by way of written response. We believe we now have a path to finalize the device element of our IND hold complete response. The nonclinical studies to address the inhalation toxicology aspect of the hold are ongoing: these results are required for the submission of our complete response to the FDA.

GH002

GH002 is our proprietary intravenous mebufotenin (5-MeO-DMT) product candidate. With GH002, we have recently completed a Phase 1, dose-ranging clinical pharmacology trial in healthy volunteers (GH002-HV-105). This trial demonstrated that GH002 was well-tolerated and produced potent pharmacodynamic (PD) effects, as assessed by psychoactive effect intensity, with an ultra-rapid onset and short duration psychoactive experience. The pharmacokinetic (PK) profile of GH002 correlated with the ultra-rapid profile of the psychoactive effects.

¹ Includes expenses that relate to any combination of GH001, GH002 and/or GH003 and exploratory work for potential future product candidates.

Research and development expenses increased by $2.6 million to $9.8 million for the three months ended June 30, 2024, from $7.2 million for the three months ended June 30, 2023. The increase is primarily due to increased expenses relating to our clinical development activities including clinical trials and nonclinical activities, partly offset by a decrease in technical development expenses. Employee expenses also increased primarily due to the hiring of personnel to support our research and development activities.

Our research and development expenses for our product candidates have fluctuated from period to period, and are likely to fluctuate, primarily due to the nature and timing associated with the various lifecycle stages of each candidate.

Research and development expenses relating to GH001 increased by $2.3 million in the three months ended June 30, 2024, primarily due to an increase in our clinical development activities including clinical trials, and nonclinical activities, partly offset by a decrease in technical development expenses.

Research and development expenses relating to multiple product candidates increased by $0.4 million in the three months ended June 30, 2024, primarily due to an increase in our clinical development activities, including nonclinical activities, and increased employee expenses. These increases have been partly offset by a decrease in technical development expenses.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the three months ended June 30, 2024 and 2023:

	Three months ended June 30

¹ Includes a share-based compensation credit of $8 thousand and a share-based compensation expense of $0.2 million for the three months ended June 30, 2024 and 2023, respectively.

General and administrative expenses increased by $0.7 million to $3.5 million for the three months ended June 30, 2024, from $2.7 million for the three months ended June 30, 2023. The increase is primarily due to an increase in professional fees and employee expenses in our general and administrative functions to support our growth initiatives.

Net Finance Income

Our net finance income increased to $2.4 million for the three months ended June 30, 2024, from $2.2 for the three months ended June 30, 2023. The increase is primarily due to an increase in finance income of $0.5 million relating to cash, cash equivalents and other financial assets, partly offset by a decrease relating to the movement in expected credit losses.

Foreign Exchange Gain

Foreign exchange gain is $0.5 million for the three months ended June 30, 2024, a movement of $0.4 million from a gain of $36 thousand for the three months ended June 30, 2023. This movement is primarily as a result of the translation of the U.S. dollar cash and other financial assets balances in the accounts of our subsidiary into its functional currency, which is the euro. During the three months ended June 30, 2024, the U.S. dollar strengthened compared to the euro, which resulted in the foreign exchange gain.

¹ Includes share-based compensation expense of $0.1 million and $0.4 million for the six months ended June 30, 2024 and 2023, respectively.

General and administrative expenses increased by $0.5 million to $6.3 million for the six months ended June 30, 2024, from $5.9 million for the six months ended June 30, 2023. The increase is primarily due to an increase in professional fees and employee expenses in our general and administrative functions to support our growth initiatives.

Net Finance Income

Our net finance income increased by $1.6 million for the six months ended June 30, 2024, from $3.3 million for the six months ended June 30, 2023. The increase is primarily due to an increase in finance income of $1.1 million on cash, cash equivalents and other financial assets, as well as an increase in the fair value gain on cash equivalents and other financial assets of $0.6 million.

Foreign Exchange Gain/(Loss)

Foreign exchange gain is $1.8 million for the six months ended June 30, 2024, a movement of $3.4 million from a loss of $1.6 million for the six months ended June 30, 2023. This movement is primarily as a result of the translation of the U.S. dollar cash and other financial assets balance in the accounts of our subsidiary into its functional currency, which is the euro. During the six months ended June 30, 2024, the U.S. dollar strengthened compared to the euro, which resulted in the foreign exchange gain.

Liquidity and Capital Resources

Sources of Liquidity

We have incurred operating losses since inception, and we have not generated any revenue from any product sales or any other sources. We have not yet commercialized any of our product candidates, which are in various phases of technical and clinical development, and we do not expect to generate revenue from sales of any products for several years, if at all. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. We have funded our operations to date primarily through equity financings, including our initial public offering. As of June 30, 2024, we had cash, cash equivalents, other financial assets and marketable securities of $204.5 million, compared to cash, cash equivalents and marketable securities of $222.7 million as of December 31, 2023.

We plan to continue to fund our operating and capital funding needs through sales of additional equity or other forms of financing. We may also consider pursuing strategic partnerships for clinical development and commercialization of our product candidates. The sale of additional equity would result in additional dilution to our shareholders.

Cash Flows

The following table provides information regarding our cash flows for the six months ended June 30, 2024 and 2023:

	Six months ended June 30
	2024		2023		Change
	(in USD thousands)
Net cash flows used in operating activities	(19,532	)	(14,911	)	(4,621	)
Net cash flows from/(used in) investing activities	28,520		(54,068	)	82,588
Net cash flows used in financing activities	(185	)	(107	)	(78	)
Net increase/(decrease) in cash and cash equivalents	8,803		(69,086	)	77,889

Net Cash Flows Used in Operating Activities

Net cash flows used in operating activities increased by $4.6 million to $19.5 million for the six months ended June 30, 2024, from $14.9 million for the six months ended June 30, 2023, due to an increase in loss from operations for the period and movement in working capital.

Net Cash Flows From/(Used in) Investing Activities

Net cash flows from investing activities for the six months ended June 30, 2024, is $28.5 million, a movement of $82.6 million from net cash flows used in investing activities of $54.1 million for the six months ended June 30, 2023. The net cash from investing activities during the six months ended June 30, 2024, comprised the receipt of proceeds from the sale of financial assets of $15.0 million and the redemption of marketable securities of $13.5 million. The net cash used in investing activities during the six months ended June 30, 2023, was primarily due to an investment in a money market fund of $54.0 million.

Funding Requirements

We expect our expenses to continue to increase substantially in connection with our ongoing research and development activities, particularly as we advance the technical development work, nonclinical studies and clinical trials of our product candidates and the medical devices required to deliver such product candidates, such as our proprietary aerosol delivery device for GH001. In addition, if we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing and distribution. Furthermore, we have incurred and expect to continue to incur additional costs associated with operating as a public company. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, convertible debt financings, strategic collaborations and licensing arrangements. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. Our future capital requirements will depend on many factors, which are outlined in our annual report on Form 20-F for the year ended December 31, 2023 and this discussion and analysis. We believe that we have sufficient financial resources available to cover our planned cash outflows for at least the next twelve months.

Critical Accounting Estimates

There have been no material changes to the significant accounting policies and significant judgments and estimates from those referred to in the section in our annual report on Form 20-F for the year ended December 31, 2023, titled “Item 5. Operating and Financial Review and Prospects—E. Critical Accounting Estimates.”

Emerging Growth Company Status

On April 5, 2012, the Jumpstart our Business Act of 2012 (“JOBS Act”) was enacted. As an emerging growth company, or EGC, we rely on exemptions and reduced reporting requirements under the JOBS Act including exemptions from (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board, regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis.

We will remain classified as an EGC until the earlier of (1) the last day of the fiscal year (i) in which we have total annual gross revenue of $1.235 billion; (ii) following the fifth anniversary of the completion of our initial public offering; or (iii) in which we are deemed to be a “large accelerated filer,” which requires the market value of our ordinary shares that is held by non-affiliates to exceed $700 million as of the prior June 30^th, and (2) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three-year period.

Recently Issued Accounting Pronouncements

As disclosed in note 2 to our unaudited condensed consolidated interim financial statements, there are no standards that are mandatory for the financial year beginning on January 1, 2024, that are relevant to and have had any material impact on our unaudited condensed consolidated interim financial statements. The review of the impact of new standards on our unaudited condensed consolidated interim financial statements, including the recently issued IFRS 18 “Presentation and Disclosure in Financial Statements”, which is not yet effective and which has not been early adopted by us is ongoing.

Risk Factors

There have been no material changes in our risk factors from those disclosed in our annual report on Form 20-F for the year ended December 31, 2023.

•	Phase 1 clinical trial to evaluate proprietary aerosol delivery device in healthy adult subjects approved in the UK and recruiting

•	Cash, cash equivalents, other financial assets and marketable securities of $204.5 million

DUBLIN, Ireland, September 3, 2024 (GLOBE NEWSWIRE) -- GH Research PLC (Nasdaq: GHRS), a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders, today reported financial results for the second quarter ended June 30, 2024, and provided updates on its business.

Business Updates

We announced today, in a separate press release, the promotion of Dr. Velichka “Villy“ Valcheva, MD, MSc. to Chief Executive Officer of the Company. Dr. Valcheva succeeds PD Dr. med. Theis Terwey, co-founder of GH Research.

GH001 in Patients with TRD

GH001 in Patients with PPD and BDII

GH001 is being investigated in a proof-of-concept clinical trial in patients with postpartum depression (PPD) (GH001-PPD-203). We expect GH001-PPD-203 completion in the fourth quarter of 2024.

GH001 is also being investigated in a proof-of-concept clinical trial in bipolar II disorder in patients with a current depressive episode (BDII) (GH001-BD-202).

Second Quarter 2024 Financial Highlights

Cash position

Cash, cash equivalents, other financial assets and marketable securities were $204.5 million as of June 30, 2024, compared to cash, cash equivalents, other financial assets and marketable securities of $222.7 million as of December 31, 2023. Other financial assets are comprised of money market funds, and marketable securities are comprised of investment grade bonds. We believe that our existing cash, cash equivalents, other financial assets and marketable securities will be sufficient for us to fund our operating expenses and capital expenditure requirements into 2026.

Research and development expenses

R&D expenses were $9.8 million for the quarter ended June 30, 2024, compared to $7.2 million for same quarter in 2023. The increase is primarily due to increased expenses relating to our clinical development activities including clinical trials and nonclinical activities, partly offset by a decrease in technical development expenses.

General and administrative expenses

G&A expenses were $3.5 million for the quarter ended June 30, 2024, compared to $2.7 million for the same quarter in 2023. The increase is primarily due to an increase in professional fees and employee expenses in our general and administrative functions to support our growth initiatives.

Net loss

Net loss was $10.4 million, or $0.20 loss per share, for the quarter ended June 30, 2024, compared to $7.7 million, or $0.15 loss per share, for the same quarter in 2023.

About GH Research PLC

GH Research PLC is a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders. GH Research PLC’s initial focus is on developing its novel and proprietary mebufotenin (5-MeO-DMT) therapies for the treatment of patients with treatment-resistant depression (TRD).

GH Research PLC’s annual report on Form 20-F filed with the U.S. Securities and Exchange Commission for the year ended December 31, 2023 is available at www.ghres.com and shareholders may receive a hard copy free of charge upon request.

About GH001

Our lead product candidate, GH001, is formulated for mebufotenin (5-MeO-DMT) administration via a proprietary inhalation approach. With GH001, we have completed two Phase 1 healthy volunteer clinical trials and a Phase 1/2 clinical trial in patients with TRD. Based on the observed clinical activity, where 87.5% of patients with TRD achieved ultra-rapid remission with our GH001 individualized single-day dosing regimen in the Phase 2 part of the trial, we believe that GH001 has the potential to change the way TRD is treated today.

About GH002 and GH003

GH002 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intravenous approach. We have completed a Phase 1 trial of GH002 in healthy volunteers. GH003 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intranasal administration approach. GH003 is currently in preclinical development. We anticipate developing GH002 and GH003 within our focus areas of psychiatric and neurological disorders.

Basis of preparation, significant judgments, and accounting policies (Policies)	6 Months Ended

Basis of preparation, significant judgments, and accounting policies [Abstract]
Basis of preparation	Basis of preparation Compliance with IFRS Accounting Standards The unaudited condensed consolidated interim financial statements for the three and six months ended June 30, 2024 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, 2023, which were prepared in accordance with IFRS Accounting Standards as adopted 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, 2023, are expected to be filed with the Companies Registration Office by November 26, 2024. 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, 2024, that are relevant to the Group and that have had any material impact in the interim period. The review of the impact of new standards on the Group’s financial statements which are not yet effective and which have not been early adopted by the Group is ongoing. This includes the recently issued IFRS 18 “Presentation and Disclosure in Financial Statements”. There are no other amendments to standards and interpretations that are not yet effective which have been deemed relevant to the Group. 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, 2024. As a result, the Group is not exposed to liquidity risk through requests for early repayment of loans. As of June 30, 2024, the Group’s cash and cash equivalents amounted to $87.1 million (December 31, 2023: $78.4 million). The Group also held marketable securities of $75.4 million and other financial assets of $42.0 million as of June 30, 2024 (December 31, 2023: marketable securities of $88.7 million and other financial assets of $55.6 million). The marketable securities held by the Group are quoted in active markets and are an additional source of liquidity. 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	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, 2023.
Current and deferred income tax	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, 2024 and 2023, 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.
Research and development tax credits	Research and development tax credits As explained in the Group’s consolidated financial statements for the year ended December 31, 2023, an amount of $1.3 million had remained unrecognized with respect to research and development tax credit claims for the year ended December 31, 2022 and 2021. In the six months ended June 30, 2024, an amount of $0.8 million has been received by the Group which has been recognized as a deduction from research and development expenses under the Group’s relevant accounting policy. At June 30, 2024, a balance of $0.5 million remains unrecognized as it has been concluded that reasonable assurance has not been achieved. Judgment was applied in this determination.
Segment reporting	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.
