Nyxoah Reports Third Quarter 2023 Financial and Operating Results

Partners with ResMed Germany to increase OSA awareness and therapy penetration

Mont-Saint-Guibert, Belgium – November 8, 2023 10:05pm CET / 4:05pm ET – Nyxoah SA (Euronext Brussels/Nasdaq: NYXH) (“Nyxoah” or the “Company”), a medical technology company focused on the development and commercialization of innovative solutions to treat Obstructive Sleep Apnea (OSA), today reported financial and operating results for the third quarter of 2023.

Recent Financial and Operating Highlights

Filed the third module in the modular PMA submission.

Accelerated U.S. pre-commercialization efforts, focused on market access around CPT coding.

Initiated a commercial partnership with strategic investor ResMed in Germany. This collaboration introduces a novel continuum of care into the German OSA market.

Reported third-quarter sales of €1.0 million and ended the quarter with 46 active German accounts.

Ended the quarter with a cash position of €72.5 million, providing an anticipated cash runway into late 2024.

“Nyxoah is entering one of the most exciting times in the company’s history. We will report data from our DREAM U.S. pivotal trial early next year, shortly thereafter complete our modular PMA submission, and expect FDA approval late 2024,” commented Olivier Taelman, Chief Executive Officer. “Hypoglossal nerve stimulation (HGNS) remains highly underpenetrated and guiding patients through their OSA journey is key to unlocking the market’s potential. Our agreement with ResMed Germany, which takes ResMed from a valued investor to commercial partner, creates a continuum of care that directs patients towards the appropriate treatment, resulting in greater therapy penetration.”

A.	*CLINICAL UPDATE*

DREAM US: IDE PIVOTAL STUDY

Nyxoah initiated its pivotal DREAM IDE trial in the United States in December 2020 to support an application seeking FDA marketing authorization and, ultimately, reimbursement in the U.S. for bilateral hypoglossal nerve stimulation for the treatment of moderate-to-severe obstructive sleep apnea (“OSA”). The DREAM trial is a multicenter, prospective, open-label trial in which patients who undergo implantation of the Genio^® system will be followed for five years post-implantation to assess the safety and efficacy of the Genio^® system in patients with moderate-to-severe OSA.

The trial was initially expected to enroll 134 patients who will undergo the implantation procedure with 12-month effectiveness and safety primary endpoints across 18 centers in the United States and six international sites. In April 2022, the FDA approved the Company’s request to reduce the trial’s sample size to 115 patients from 134 after reviewing data from the BETTER SLEEP trial (see below).

The primary safety endpoint is incidence of device-related severe adverse events ("SAEs") at 12-months post implantation. The co-primary effectiveness endpoints are the percentage of responders with at least a 50% reduction on the apnea-hypopnea index ("AHI") with hypopneas associated with a 4% oxyhemoglobin desaturation and a remaining AHI with hypopneas associated with a 4% oxyhemoglobin desaturation less than 20, and a 25% reduction on the oxygen desaturation index ("ODI") between baseline and 12-month visits. Patients with moderate to severe OSA (AHI score between 15 and 65) and aged between 22 and 75 years are eligible for enrolment if they failed, did not tolerate or refused positive airway pressure ("PAP") treatment. Patients with a body mass index above 32 kg/m2, a complete concentric collapse ("CCC") observed during a drug induced sleep endoscopy and combined central and mixed AHI above 25% at baseline polysomnography are to be excluded.

Enrollment in the DREAM trial is now complete, and 115 patients have undergone a Genio® implantation procedure. The company presented 12-month efficacy data on the first 34 DREAM patients and safety data, as of March 14, 2023, on all DREAM patients demonstrating a 65% AHI responder rate, a 76% ODI responder rate and safety in-line with expectations. These data are preliminary and not conclusive of final DREAM success. For the trial to be successful, of the 115 patients, at least 63% of patients need to be AHI and ODI responders at the 12-month follow-up. The Company anticipates having 12-month clinical data in the first half of 2024 and, as of the date of this report, has submitted the first three modules in the modular PMA.

BETTER SLEEP: ACHIEVED PRIMARY ENDPOINT IN BOTH CCC AND NON-CCC PATIENT COHORTS

In March 2022, the Company attended the World Sleep Congress in Rome, Italy, and presented data generated from its BETTER SLEEP trial, a multicenter, prospective, open-label, two-group clinical trial, designed to assess the long-term safety and performance of the Genio® system for the treatment of adult OSA patients with and without CCC of the soft palate over a period of 36 months post-implantation. The BETTER SLEEP trial included a subgroup of CCC patients, which is a patient population that is contraindicated for unilateral hypoglossal nerve stimulation.

In the BETTER SLEEP trial, 42 patients were implanted with the Genio® system, 18 of whom presented with CCC (or 42.9% of the total implanted population) at eight research centers in Australia. The primary safety endpoint was the incidence of device-related SAEs six months post-implantation. The primary performance endpoint was achieving at least a 4-point reduction in the apnea-hypopnea index (4% oxygen desaturation, or AHI4) from baseline at six months for the entire patient cohort. Patients with moderate to severe AHI scores (15 < AHI < 65) and aged between 21 and 75 years were eligible for enrollment if they failed, refused or did not tolerate PAP treatment. Patients with a body mass index above 32 kg/m2 were excluded.

Three patients in the non-CCC arm and three patients in the CCC arm did not complete their six-month polysomnography, and as a result, the analysis was calculated based on 36 patients (21 non-CCC and 15 CCC). Of these 36 patients, there were 23 responders (64%), including nine of the 15 CCC patients (60%) and 14 of the 21 non-CCC patients (67%), at six months. The overall reduction was statistically significant with an 11-point reduction (p<0.001), with statistically significant reductions of 10 points (p=0.001) in the CCC cohort and 11 points (p<0.001) in the non-CCC cohort. In addition, mean AHI4 reduction exceeded 70% among responders in both CCC and non-CCC cohorts. These results are subject to final review and validation.

With respect to the primary safety endpoint, preliminary unadjudicated safety data showed four SAEs in three patients during the six-month post-implantation period. Of those, two SAEs in one patient were reported as device related, one SAE in one patient was reported as procedure and device related, and one SAE in one patient was reported as unrelated to procedure or device. Final review and adjudication of SAEs and adverse events ("AEs") have not yet been completed by an independent clinical events committee and as a result the characterization of SAEs or AEs could be subject to change.

While additional data, including responder rates, remains subject to ongoing review and continues to be analyzed, the Company observed in the per protocol group a 70% responder rate in the non-CCC patient subgroup based on the Sher criteria. The per protocol group consisted of 35 patients and excluded five patients from the mITT analysis population: two of these patients were lost to follow-up, one patient did not comply with the study protocol, and two patients were removed from the study by the investigator, one for hostility towards staff and one having returned to continuous positive airway pressure, therapy.

The Company expects to announce additional data with respect to the trial as further analyses are conducted and seeks to publish the full data set from the trial in a peer-reviewed publication. There will be no additional enrollment in the BETTER SLEEP trial. However, the Company will continue to monitor patients in the evaluable patient population and plan to continue evaluating over the course of three years following implantation.

The data generated from this study were used to expand the Company’s CE mark for the Genio® system to treat patients demonstrating CCC at the soft palate level, and the first commercial Genio® implants occurred in CCC patients in Germany during the first quarter of 2022.

ACCCESS U.S. IDE STUDY SEEKING APPROVAL TO TREAT CCC PATIENTS

In the United States, supported by the BETTER SLEEP study data, the FDA in September 2021 granted Breakthrough Device Designation for the Genio® system in order to shorten the approval path to treat CCC patients. Following a series of sprint discussions with the FDA regarding the design of a trial called ACCCESS to assess the safety and efficacy of the Genio® system on CCC patients, the FDA approved the Company’s IDE application in July 2022.

In this study, Nyxoah will implant up to 106 patients across up to 40 implant sites with co-primary efficacy endpoints of AHI responder rate, per the Sher criteria, and ODI responder rate, both assessed at 12 months post-implant. The clinical sites are being activated, and the first patients have undergone a Genio® implantation procedure.

B.	*EUROPEAN COMMERCIALIZATION*

During the first nine months of 2023, Nyxoah recognized total revenue of €2.5 million, primarily in Germany. After securing DRG reimbursement in Germany during the first quarter of 2021, Nyxoah built and expanded its German commercial organization to a total of 14 full time employees.

Nyxoah’s commercial strategy is focused on creating a Center of Excellence ecosystem, with a high level of clinical expertise between implanting ENT surgeons and sleep physicians who are able to provide more treatment options to their large patient pools. As of September 30, 2023, the Company has activated 46 Tier 1 sites across Germany.

The Company has also focused on entering new European markets. The Company has secured DRG reimbursement in Switzerland, state reimbursement in Austria, and is looking into additional opportunities to enter several other countries. Nyxoah has also generated revenue in Switzerland, Austria and Spain, and the Company expects to expand into other European countries.

2.	FINANCIAL HIGHLIGHTS

Revenue was €2.5 million for the nine months ended September 30, 2023, compared to €1.8 million for the nine months ended September 30, 2022 with strong acceleration in Q3 2023.

Cost of goods sold was €0.9 million for the nine months ended September 30, 2023, compared to €0.7 million cost for the nine months ended September 30, 2022.

Selling, general and administrative expenses increased by €3.3 million or 24 % from €13.5 million for the nine months ended September 30, 2022 to €16.8 million for the nine months ended September 30, 2023, mainly due to an increase of costs to support the commercialization of Genio® system in Europe, scale up of the Company and also due to a start of new ERP system implementation.

Before capitalization of €7.0 million for the nine months ended September 30, 2023 and €11.9 million for the nine months ended September 30, 2022, research and development expenses increased by €3.1 million or 13 %, from €23.2 million for the nine months ended September 30, 2022, to €26.3 million for the nine months ended September 30, 2023, due to the combined effect of higher clinical, R&D activities and manufacturing expenses. This increase is mainly in staff, consulting costs and in manufacturing and outsourced development to support those activities, these increases were offset by a decrease of €2.7 million in clinical study activities due to Dream Study.

Nyxoah realized a net financial income of €0.8 million for the nine months ended September 30, 2023 primarily driven by the exchange rate depreciation of dollar versus euro and by interest income related to term accounts. This compares to a net positive financial result of €5.9 million for the nine months ended September 30, 2022, during which dollar appreciated versus euro.

Nyxoah realized a net loss of €32.3 million for the nine months ended September 30, 2023, compared to a net loss of €17.9 million for the nine months ended September 30, 2022.

Cash and cash equivalents

On September 30, 2023, cash and cash equivalents and financial assets totaled €72.5 million, compared to €94.9 million on December 31, 2022. The decrease in cash and cash equivalents resulted mainly from net cash used in operating activities of €33.1 million and net cash from investing activities of €11.2 million and offset by net cash flows from financial activities of €17.9 million due to capital increase. See note 16.

3.	2023 OUTLOOK

The Company expects to continue ramping up sales in Germany as well as in other European countries where we are already present.

In the US, the Company will focus on patient follow-up in the DREAM IDE trial resulting in reaching primary endpoints, continue to enroll the ACCCESS IDE study for CCC patients and begin preparations to enter the US market with regulatory, manufacturing, commercial and market access readiness.

4.	RISK FACTORS

We refer to the description of risk factors in the Company's 2022 annual report, pp. 60-83. In summary, the principal risks and uncertainties faced by us relate to our financial situation and need for additional capital, clinical development of our product candidates, commercialization and reimbursement of our product candidates, our dependence on third parties and on key personnel, the markets and countries in which we operate, the manufacturing of our product candidates, legal and regulatory compliance matters, our intellectual property, our organization and operations.

Notes to the unaudited condensed interim consolidated financial information

1. General information

Nyxoah SA (the “Company”) is a public listed company with limited liability (naamloze vennootschap/société anonyme) incorporated and operating under the laws of Belgium and is domiciled in Belgium. The Company is registered with the legal entities register (Brabant Walloon) under enterprise number 0817.149.675. The Company’s registered office is in Rue Edouard Belin 12, 1435 Mont-Saint-Guibert, Belgium.

The Company is a medical technology company focused on the development and commercialization of innovative solutions to treat Obstructive Sleep Apnea, or OSA. Our lead solution is the Genio^® system, a CE-Marked, patient-centric, minimally invasive, next generation hypoglossal neurostimulations therapy for OSA. OSA is the world’s most common sleep disordered breathing condition and is associated with increased mortality risk and comorbidities including cardiovascular diseases, depression and stroke.

The Genio® system is the first neurostimulation system for the treatment of OSA to include a battery-free and leadless neurostimulator capable of delivering bilateral hypoglossal nerve stimulation to keep the upper airway open. The product is intended to be used as a second-line therapy to treat moderate to severe OSA patients who have either not tolerated, failed or refused conventional therapy, including Continuous Positive Airway Pressure, or CPAP, which, despite its proven efficacy, is associated with many limitations, meaning compliance is a serious challenge. In addition, other second-line treatments are more suitable to treat mild to moderate OSA (such as oral devices) or highly invasive. Compared to other hypoglossal nerve stimulation technologies for the treatment of OSA, the Genio^®system is a disruptive, differentiating technology that targets a clear unmet medical need thanks to its minimally invasive and quick implantation technique, its external battery and its ability to stimulate the two branches of the hypoglossal nerve.

Obstructive sleep apnea is the world’s most common sleep disordered breathing condition. OSA occurs when the throat and tongue muscles and soft tissues relax and collapse. It makes a person stop breathing during sleep, while the airway repeatedly becomes partially (hypopnea) or completely (apnea) blocked, limiting the amount of air that reaches the lungs. During an episode of apnea or hypopnea, the patient’s oxygen level drops, which leads to sleep interruptions.

Nyxoah SA has four wholly owned subsidiaries: Nyxoah Ltd, a subsidiary of the Company since October 21, 2009 (located in Israel and incorporated on January 10, 2008 under the name M.L.G. Madaf G. Ltd), Nyxoah Pty Ltd since February 1, 2017 (located in Australia), Nyxoah Inc. since May 14, 2020 (located in the USA) and Nyxoah GmbH since July 26, 2023 (located in Germany).

The interim condensed consolidated financial statements of Nyxoah SA and its subsidiaries (collectively, the Group) as of September 30, 2023 and for the three and nine months ended September 30, 2023, have been authorized for issue on November 8, 2023 by the Board of Directors of the Company.

2. Significant accounting policies

Basis of Preparation of the interim condensed consolidated financial statements

The Company’s interim condensed consolidated financial statements have been prepared in accordance with International Accounting Standard 34 – Interim Financial Reporting (“IFRS”), as issued by the International Accounting Standards Board (IASB). They do not include all the information required for complete annual financial statements and should be read in conjunction with the Company’s last annual consolidated financial statements as at and for the year ended December 31, 2022.

Except for the application of standards, interpretations and amendments being mandatory as of January 1, 2023, the accounting policies used for the preparation of the interim condensed consolidated financial statements are consistent with those used for the preparation of the Company’s annual consolidated financial statements as of and for the year ended December 31, 2022.

The consolidated financial statements are presented in thousands of Euros (€) and all values are rounded to the nearest thousands, except when otherwise indicated (e.g. € million).

The preparation of the interim condensed consolidated financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgement or complexity, are areas where assumptions and estimates are significant to the consolidated financial statements. The critical accounting estimates used in the preparation of the interim consolidated financial statements are consistent with those followed in the preparation of the Company’s annual consolidated financial statements as of and for the year ended December 31, 2022.

Going concern principle

The Unaudited Interim Condensed Consolidated Financial Statements have been prepared on a going concern basis. As at September 30, 2023, the Company had cash and cash equivalents of €13.3 million and financial assets of €59.2 million. Based on cash flow forecasts for the remaining period of 2023 and 2024, which include significant expenses and cash outflows in relation to – among others – the ongoing clinical trials, the continuation of research and development project, and the scaling up of the Company’s manufacturing facilities. The Company believes that this cash position will be sufficient to meet the Company’s capital requirements and fund its operations for at least 12 months as from the date these financials are authorized for issuance.

New and amended standards and interpretations applicable

Effective for the annual periods beginning on January 1, 2023

The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

Several amendments and interpretations apply for the first time in 2023, but do not have an impact on the interim condensed consolidated financial statements of the Company:

IFRS 17 Insurance Contracts (applicable for annual periods beginning on or after January 1, 2023)

Amendments to IFRS 17 Insurance contracts: Initial Application of IFRS 17 and IFRS 9 – Comparative Information (applicable for annual periods beginning on or after January 1, 2023)

Amendments to IAS 1 Presentation of Financial Statements and IFRS Practice Statement 2: Disclosure of Accounting Policies (applicable for annual periods beginning on or after January 1, 2023)

Amendments to IAS 8 Accounting policies, Changes in Accounting Estimates and Errors: Definition of Accounting Estimates (applicable for annual periods beginning on or after January 1, 2023)

Amendments to IAS 12 Income Taxes: Deferred Tax related to Assets and Liabilities arising from a Single Transaction (applicable for annual periods beginning on or after January 1, 2023)

Amendments to IAS 12 Income taxes: International Tax Reform – Pillar Two Model Rules (effective immediately – disclosures are required for annual periods beginning on or after 1 January 2023). The Group will not be subject to Pillar Two Model rules.

3. Critical accounting estimates and assumptions

The preparation of interim financial statements in accordance with IFRS requires management to make judgments, estimates and assumptions that may significantly affect the reported amounts of revenues, expenses, assets and liabilities, and the disclosure of contingent liabilities at the end of the reporting period.

Refer to the disclosure note 5 from the Group’s 2022 year-end consolidated financial statements for further details about the main critical accounting estimates and assumptions.

4. Segment reporting

Based on the organizational structure, as well as the nature of financial information available and reviewed by the Company’s chief operating decision makers to assess performance and make decisions about resource allocations, the Company has concluded that its total operations represent one reportable segment. The chief operating decision maker is the CEO.

5. Fair Value

The carrying amount of cash and cash equivalents, trade receivables, other receivables, other current assets and financial assets approximate their value due to their short-term character.

The carrying value of current liabilities approximates their fair value due to the short-term character of these instruments. The fair value of non-current liabilities (financial debt and other non-current liabilities), excluding the derivative financial liabilities, is evaluated based on their interest rates and maturity date. These instruments have fixed interest rates and their fair value measurements are subject to changes in interest rates. The fair value measurement is classified as level 3.

The derivative financial liabilities and assets which consist of foreign currency options and foreign currency forwards are measured at fair value through profit and loss. Fair value is determined by the financial institution and is based on foreign currency forwards rates and the maturity of the instrument.

On top of that an existing lease contract has been extended, resulting in an increase of the RoU asset and lease liability with €0.8 million. The repayments of lease liabilities amounted to €0.6 million (2022: €497,000). The depreciations on the right of use assets amounted to €0.6 million and €0.5 million for the nine months ended September 30, 2023, and 2022, respectively.

10. Other long-term receivables

The increase in other long-term receivables is due to an R&D tax incentive in Belgium for an amount of 493,000 € in relation to certain development activities and clinical trials. The Company recognizes the research and development incentive as a long-term receivable (expected to be received in cash in 2026) and as a deduction from the carrying amount of the intangible asset.

Total Inventory		1 709		882

The increase in inventory is due to increasing activities to prepare for the commercialization and further scale-up of the Company in 2023. For the period ended September 30, 2023 and the year ended December 31, 2022 the Company did not recognize any expenses for inventory write-offs since the inventory level is expected to be sold in the foreseeable future.

Foreign currency swaps		21		1
Other		403		422
Total trade and other receivables		4 355		3 238

The increase of €1.1 million in trade and other receivables is mainly due to an increase in trade receivables by €455,000, an increase in current tax receivable by €467,000 and an increase in R&D incentive receivables by €335,000 which is partially offset with a decrease by €141,000 in VAT receivable.

The Company may include unbilled receivables in its accounts receivable balance. Generally, these receivables represent earned revenue from products delivered to customers, which will be billed in the next billing cycle. All amounts are considered collectible and billable. As at December 31, 2022 and September 30, 2023, there were no unbilled receivables included in the trade receivables.

R&D incentive receivables relates to incentives received in Australia as support to the clinical trials and the development of the Genio^®system.

The current tax receivable relates to excess payment of corporate income tax in Israel, US and Belgium. The increase by €188,000 in US can be explained by the finalization of the R&D tax credit study during Q3 2023. We refer to note 20 for more details. On top of that the increase in Belgium by €347,000 is explained by an increase in withholding tax on interest for term deposit accounts.

Other mainly relates advance payments and withholding tax to be received related to Belgian R&D employees.

13. Other current assets

The increase of €399,000 in other current assets as at September 30, 2023 is due to increase in accrued interest on the term deposits by €0,6 million which is partly offset by a decrease in prepaid expenses by €230,000.

Cash and cash equivalents decreased to €13.3 million as at September 30, 2023, compared to €17.9 million as at December 31, 2022 with a decrease of current accounts by €10.6 million which is partially offset by an increase of short term deposits (less than 3 months) by €6.0 million

15. Financial assets

Current financial assets relate to term accounts with an initial maturity longer than 3 months but less than 12 months measured at amortized costs.

In 2023, the Company entered into USD term deposits and US Treasury bills for a total amount $US 66.0 million (€60.5 million) and €11.0 million. During the period ended as at September 30, 2023, $US 47.0 million (€43.6 million) and €47.0 million reached maturity and is subsequently held as cash.

As per September 30, 2023, the current financial assets consists of $US 48.9 million (€46.2 million), which could generate a foreign currency exchange gain or loss in the financial results in accordance with the fluctuations of the USD/EUR exchange rate as the Company’s functional currency is EUR, and €13.0 million.

On March 24, 2023, the Company reduced the exercise price of 75% of the warrants previously granted to warrant holders under the 2021 Warrants Plan to 5.42 EUR to reflect the decrease in the company’s share price. For the remaining 25% of the warrants previously granted under the 2021 Warrants Plan, the exercise price will remain unchanged. All other terms and conditions of the re-priced warrants remain unchanged to the original option agreement. The Company determined the fair value of the options at the date of the modification (March 24, 2023). The incremental fair value of the re-priced warrants will be recognised as an expense over the period from the modification date to the end of the vesting period. For the warrants already vested at the date of modification, the incremental fair value is fully recognised as an expense at date of modification.

The fair value of the modified warrants was determined using the same models and principles as described above, with the following model inputs:

Payables	2 148	1 873
Invoices to be received	2 332	3 112
Total Trade payables	4 480	4 985

The decrease in total trade payables of €0.5 million as at September 30, 2023 is due to a decrease in invoices to be received of €0.8 million which is compensated by the increase in trade payables of €275,000.

20. Income taxes and deferred taxes

	For the three months ended September 30						For the nine months ended September 30
(in EUR 000)	2023			2022			2023			2022
Current tax income/(expense)		2 236			(944	)		1 121			(2 579)
Deferred tax income/(expense)		(7	)		879			(2	)		2 200
Total Income Tax Income/(Expense)		2 229			(65	)		1 119			(379	)

As of January 1, 2022, new tax regulations are in place in the US in which R&D expenses could no longer be deducted when incurred but instead they should be capitalized only for tax purposes and amortized over a 5 year period. A current tax liability as well as a deferred tax asset were recognized. This deferred tax asset was reversed as per December 31, 2022. During the three months ended September 30, 2023, the Company finalized its R&D tax credit study and reached the conclusion that R&D expenses can be deducted when incurred. The R&D tax credit study concluded that taking into account that the research and development by the US subsidiary was done under the direction of the parent in Belgium and benefited Belgian parent’ business, the expenditures in the US should be deducted when incurred. As a result the current tax liability amounting to €2.2 million was reversed during the three months ended September 30, 2023.

The current tax liability of €2.4 million includes a liability for uncertain tax positions for an amount of €2.3 million and an income tax liability for an amount of €56,000. The uncertain tax position was recorded following certain public rulings and guidance issued by tax authorities in one of the jurisdictions that the Company operates in. For the nine months ended September 30, 2023, an additional accrual of the liability for uncertain tax positions was recorded for an amount of €363,000 (2022: €69,000).

Foreign currency option - current		1 013		10
Other		228		131
Total other payables		6 052		5 167

The increase of €0.9 million in other payables as at September 30, 2023, compared to December 31, 2022, is the result of an increase of €1 million in the fair value of the foreign currency option and an increase in holiday pay accrual of €80,000 partly offset by a decrease of €0.3 million in salary payables.

22. Derivatives

The Company is exposed to currency risk primarily due to the expected future USD, AUD and NIS expenses that will be incurred as part of the ongoing and planned marketing, clinical trials and other related expenses. A financial risk management policy has been approved to i) generate yields on liquidity and ii) reduce the exposure to currency fluctuations with a timeline up to 24 months and by means of foreign currency swaps.

The Company has entered into several foreign currency swaps and foreign currency forwards for which the notional amounts are detailed in the table below:

	As at

23. Results of operation

Revenue and cost of goods sold

In the nine months ended September 30, 2023, the Company generated revenue for the amount of €2.5 million (2022: €1.8 million). In the three months ended September 30, 2023, the Company generated revenue for the amount of €1.0 million (2022: €182,000).

Revenue is recognized at a point in time upon satisfaction of the performance obligation, being the moment control over the Genio^® system is transferred to the customer, which is in general at delivery at customer site or a predefined location in the country of the customer. For certain customers, control may be transferred upon shipment to the customer in case the incoterms are Ex-Works. The revenue from the Genio^® system consists of a kit of products delivered at the same point in time, and as such revenue does not need to be allocated over the different products. The revenue is then recognized at an amount that reflects the consideration to which the Company expects to be entitled in exchange of the Genio^® system. In determining the transaction price for the sale of the Genio^® system, the Company considers the effects of variable consideration.

For the nine month period ended September 30, 2023 the sales (based on country of customer) were generated in Germany (€2.1 million), Switzerland (€324,000), Austria (€102,000) and Spain (€12,000) (2022: Germany: €1.6 million, Switzerland : €167,000 and Finland: €40,000). For the nine month period ended September 30, 2023, the Company has one customer with individual sales larger than 10% of the total revenue (2022: two customers).

For the three month period ended September 30, 2023 the sales (based on country of customer) were generated in Germany (€0.7 million), Switzerland (€207,000), Austria (€20,000) and Spain (€12,000) (2022: Germany: €15,000 and Switzerland: €167,000 ).
