Rhea-AI Filing Summary

Nyxoah reported second-quarter and first-half 2026 results, with H1 2026 revenue of €14.0 million, up from €2.4 million a year earlier, as U.S. commercialization of its Genio system accelerated. U.S. revenue grew 22% sequentially in Q2 2026 over Q1 2026 and reached €9.5 million for the first half, alongside €4.6 million from international markets.

Despite higher gross profit of €8.2 million, heavy investment in growth led to a net loss of €48.9 million versus €43.0 million in H1 2025, while basic loss per share improved to €0.976 from €1.149 on a larger share base. Cash and financial assets totaled €97.8 million at June 30, 2026, supported by a Q2 equity raise and additional drawdown under the European Investment Bank term loan, providing liquidity for continued U.S. launch and clinical programs.

Positive

  • H1 2026 revenue increased to €14.0 million from €2.4 million, reflecting rapid uptake of the Genio system as U.S. and international commercialization expanded.
  • Cash and financial assets reached €97.8 million at June 30, 2026, aided by an equity raise and term-loan funding, giving Nyxoah substantial liquidity to support operations and growth initiatives.

Negative

  • Nyxoah’s net loss widened to €48.9 million in H1 2026 from €43.0 million a year earlier, as higher selling, general and administrative spending and financing costs outpaced gross profit.
  • The net negative financial result deepened to €7.0 million, driven mainly by a €5.4 million fair value loss on convertible bond and synthetic warrant liabilities and €1.5 million amortization of the day 1 loss.

Filing Explained

Completed share issuance increased Nyxoah’s share count to 100,072,815 by June 30, 2026, reducing existing holders’ percentage ownership absent offsets.

Form 6-K furnishes material information published by a foreign private issuer; this filing reports Nyxoah’s completed first-half financing and interim results as of June 30, 2026.

The equity financing was completed through the issuance of 54,595,394 shares on June 9 at €1.48 per share and 637,164 shares on June 10 at €1.49; additional shares were issued on debt conversion and RSU exercise, bringing the total to 100,072,815. Issuing additional shares increases the total share count and reduces an existing holder’s percentage ownership absent offsetting changes, so this filing confirms a dilution-related change for existing common holders.

The EIB financing also included a completed €13.75 million second-tranche drawdown, recorded as debt with a five-year bullet repayment schedule, and synthetic warrants tied to that tranche; these are disclosed financing obligations and warrant mechanics, not additional shares issued in this filing.

As of June 30, 2026, 358,267 RSUs remained outstanding and are scheduled to vest at the June 2027 shareholders’ meeting, with each RSU requiring subscription for one new ordinary share at €0.1718 per share.

Management states that the €64.1 million of cash and €33.7 million of financial assets held at June 30, 2026 are adequate to cover capital needs and sustain operations for at least 12 months from the financial statements’ authorization date.

Obstructive Sleep Apnea medical
"innovative solutions to treat Obstructive Sleep Apnea (OSA)"
Obstructive sleep apnea is a common medical condition where the throat repeatedly narrows or closes during sleep, causing short pauses in breathing, drops in blood oxygen and fragmented rest. It matters to investors because it creates ongoing demand for medical devices, diagnostics, treatments and sleep-monitoring services, and it can affect population health, workforce productivity and healthcare spending—like a recurring leak in a system that requires continual repair and monitoring.
hypoglossal neurostimulation medical
"battery-free hypoglossal neurostimulation therapy for OSA"
An implantable therapy that uses electrical pulses to activate the hypoglossal nerve, which controls the tongue, to keep the upper airway open during sleep. Think of it as a pacemaker for the tongue that senses breathing and gently moves tongue muscles to prevent airway collapse. It matters to investors because device approvals, clinical results, and reimbursement influence market potential, sales, and regulatory risk for companies developing or selling this technology.
Complete Concentric Collapse (CCC) medical
"expansion of its therapeutic indications to Complete Concentric Collapse (CCC) patients"
Breakthrough Device Designation regulatory
"the FDA in September 2021 granted Breakthrough Device Designation for the Genio system"
A breakthrough device designation is a regulatory program that gives promising medical devices for serious or life‑threatening conditions priority support and faster review from a health authority (e.g., the U.S. FDA). Think of it as a “fast lane” or VIP pass through development and review: it can shorten time to market, lower regulatory uncertainty, and boost a company’s commercial prospects — but it is not an approval by itself.
synthetic warrants financial
"entered into a “synthetic warrant agreement” with the EIB"
recoverable cash advances financial
"Financial debt mainly consists of recoverable cash advances, EIB finance agreement"

“The doubling of active accounts in Q2 and the strong acceleration of our patient pipeline, demonstrate the growing acceptance and excitement around Genio by physicians and patients,” commented Olivier Taelman, Chief Executive Officer of Nyxoah. “With a dedicated Genio C-code for Medicare patients and another quarter of 100% prior-authorization approval for commercial and WISeR patients, we are confident that the current reimbursement landscape supports our accelerating U.S. revenue growth. The recent closing of our $110 million financing provides the capital needed to further invest in Genio’s U.S. commercial organization in the second half of 2026.”

Results for the Three and Six Months Ended June 30, 2026

Revenue

Net revenue in the second quarter of 2026 was 7.7 million, compared to 1.3 million in the second quarter of 2025. Net revenue in the first half of 2026 was 14.0 million, as compared to 2.4 million for the first half of 2025. The increases in net revenue were primarily driven by the continued expansion of U.S. commercialization activities following FDA approval in August 2025, as well as growth in international markets.

Cost of Goods Sold

Cost of goods sold was 3.1 million for the second quarter of 2026, resulting in gross profit of 4.6 million and a gross margin of 60% for the second quarter of 2026, compared to cost of goods sold of 0.5 million in the second quarter of 2025, resulting in gross profit of 0.9 million and a gross margin of 63% in the second quarter of 2025. The increase in cost of goods sold was primarily driven by an increase in revenue. The decrease in gross margin was primarily due to a higher mix of U.S. revenue.
Cost of goods sold in the first half of 2026 was 5.8 million, as compared to 0.9 million for the first half of 2025, resulting in gross profit of 8.2 million and a gross margin of 59% in the first half of 2026, compared to gross profit of 1.5 million and a gross margin of 63% in the first half of 2025. The decrease in gross margin was primarily due to production yield issues in the first quarter of 2026 and higher mix of U.S. revenue.

Research and Development

For the second quarter of 2026, research and development expenses were 9.5 million, versus 10.1 million for the second quarter of 2025. For the first half of 2026, research and development expenses were 18.3 million, versus 19.0 million for the first half of 2025. The decreases in research and development expenses were primarily due to a decrease in product development expenses.

Selling, General and Administrative

For the second quarter of 2026, selling, general and administrative expenses were 15.6 million, versus 10.7 million for the second quarter of 2025. For the first half of 2026, selling, general and administrative expenses were 31.0 million, versus 23.1 million for the first half of 2025. The increases in selling, general and administrative expenses were primarily driven by the continued build-out of the Companys U.S. commercial organization, including sales, marketing, and market access functions.

Operating Loss

Total operating loss for the second quarter of 2026 was 20.6 million, versus 19.9 million in the second quarter of 2025. Total operating loss for the first half of 2026 was 41.1 million, versus 40.5 million in the first half of 2025. The increases in operating loss reflect increased net revenue offset by increased investments to support the build-out of the Companys U.S. commercial organization.

Cash Position

Cash and cash equivalents and financial assets totaled €97.8 million at June 30, 2026, compared to €48.0 million at December 31, 2025.

Financial Guidance for the full year 2026

The Company continues to expect worldwide net revenue for the full year 2026 to be in the range of 36 million to 40 million.
The Company continues to expect gross margin for the full year 2026 to be in the range of 60% to 62%.
The Company now expects total operating expenses for the full year 2026 to be in the range of 99 million to 102 million. This increase of approximately 1 million is due to the one-time share-based compensation expense of approximately 0.9 million associated with the repricing of employee equity incentive arrangements recorded in the second quarter.
The Company continues to expect non-GAAP cash operating expenses for the full year 2026 to be in the range of 88 million to 90 million. Non-GAAP cash operating expenses reflect expected total operating expenses less non-cash expenses such as depreciation, amortization, and share-based compensation.

Conference call and webcast presentation

Company management will host a conference call to discuss financial results on Wednesday, August 5, 2026, beginning at 10:30pm CET / 4:30pm ET.

A webcast of the call will be accessible via the Investor Relations page of the Nyxoah website or through this link: Nyxoah’s Q2 Earnings Call Webcast. For those not planning to ask a question to management, the Company recommends listening via the webcast.

If you plan to ask a question, please use the following link: Nyxoah’s Q2 2026 Earnings Call. After registering, an email will be sent, including dial-in details and a unique conference call access code required to join the live call. To ensure you are connected prior to the beginning of the call, the Company suggests registering a minimum of 10 minutes before the start of the call.

The archived webcast will be available for replay shortly after the close of the call.

Non-GAAP financial measures

This press release includes non-GAAP (Generally Accepted Accounting Principles) financial measures, including non-GAAP cash operating expenses. Non-GAAP cash operating expenses are calculated by excluding from GAAP certain operating expense items, including depreciation, amortization, capitalized research and development expenses, impairment losses on intangible assets, and share-based compensation. These non-GAAP financial measures are presented because the Company believes they are useful indicators of its operating performance. Management uses these non-GAAP financial measures as measures of the Company’s operating performance and for planning purposes, including the preparation of the Company’s annual operating budget and financial projections. The Company believes these measures are useful to investors as supplemental information because they are frequently used by analysts, investors and other interested parties to evaluate companies in its industry. These non-GAAP financial measures should not be considered alternatives to, or superior to, any other performance measure derived in accordance with GAAP. They should not be construed to imply that the Company’s future results will be unaffected by unusual or non-recurring items. The Company’s definitions of non-GAAP cash operating expenses are not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

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.

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.

On March 19th, 2024, the Company reported the DREAM study met its primary endpoints on an intent-to-treat (ITT) basis, with an Apnea-Hypopnea Index (AHI) responder rate of 63.5% (p=0.002) and an Oxygen Desaturation Index (ODI) responder rate of 71.3% (p<0.001). Additionally, the study demonstrated a median 12-month AHI reduction of 70.8%. There were 11 serious adverse events, or SAEs, in ten subjects resulting in an SAE rate of 8.7%. Out of the 11 SAEs, three were device related and there were three explants. The Company filed the fourth and final module of the modular premarket approval (PMA) application at the end of the second quarter 2024 and received FDA approval on August 8, 2025.

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 initially intended to 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. However, in the meantime, as announced on August 11, 2025, the Company closed patient enrolment in this study prior to enrolling all 106 potential patients. The study will continue with the patients already enrolled, with said co-primary endpoints assessed at 12 months post implant and followed for five years. The Company closed enrolment prior to reaching 106 patients as it believes that the patient population already enrolled in the study will provide statistically significant results, which along with the outcomes from prior clinical evidence, will provide meaningful data with respect to the safety and efficacy of using Genio therapy in the patient population suffering from CCC.

B.COMMERCIALIZATION outside U.S.

During the first half of 2026, Nyxoah recognized net revenue of €4.6 million, primarily in Germany, which amounted to €2.6 million. After securing DRG reimbursement in Germany during the first quarter of 2021, Nyxoah built and expanded its German commercial organization to a total of 13 fulltime employees as of June 30, 2026.

Table of Contents

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 can provide more treatment options to their large patient pools.

The Company has also focused on entering new international markets:

The Company secured DRG reimbursement in Switzerland in 2021 and generated regular revenue ever since.

In Q4 2024, the Company entered the SSDP (Specialised Services Devices Program) with the NHS in the UK and generated its first revenue that same quarter.

In Q1 2025, the Company initiated commercialization in the Middle East region through a distributor agreement and generated its first revenue in Dubai that same quarter. In Q2 2025, the Company generated its first revenue in Kuwait and Abu Dhabi.

In Q4 2025, Nyxoah initiated commercialisation and generated first revenues in the Netherlands.

Nyxoah has also generated revenue in Austria, Spain and Italy and the Company expects to expand into other European countries and Middle East markets, pending feedback on submitted reimbursement dossiers.

C.FDA PMA APPROVAL AND US COMMERCIALIZATION

On August 8, 2025, the U.S. Food and Drug Administration (FDA) approved the Genio system for a subset of patients with moderate to severe OSA with an Apnea-Hypopnea Index (AHI) of greater than or equal to 15 and less than or equal to 65. The Company immediately commenced U.S. commercialization with a phased rollout at early-adopter centres, onboarding sites, shipping initial systems to hospitals/ambulatory surgery centres, and completing surgeon training. During the first half of 2026, the Company recognized net revenue of €9.5 million from sales in the U.S. As part of the FDA PMA approval, the Company will complete a post-PMA approval clinical study named BREATHE which is expected to enrol 229 patients (with a minimum of 160 evaluable patients).

2.FINANCIAL HIGHLIGHTS

Revenue was €14.0 million for the six months ended June 30, 2026, compared to €2.4 million for the six months ending June 30, 2025.

Cost of goods sold was €5.8 million for the six months ended June 30, 2026, compared to €0.9 million cost for the six months ended June 30, 2025.

Selling, general and administrative expenses increased by €7.9 million or 34.4 % from €23.1 million for the six months ended June 30, 2025 to €31.0 million for the six months ended June 30, 2026, due to an increase in costs to support the commercialization of the Genio system following FDA approval in August 2025 and an increase in legal costs related to IP litigation.

Research and development expenses decreased by €0.7 million or 3.7 %, from €19.0 million for the six months ended June 30, 2025, to €18.4 million for the six months ended June 30, 2026. The decrease is mainly due to a decrease in clinical study expenses and in R&D activities. Additionally, following FDA approval in August 2025, the amortization of the related intangible assets commenced leading to an increase in depreciation and amortization expenses.

Nyxoah realized a net negative financial result of €7.0 million for the six months ended June 30, 2026 primarily driven by a €5.4 million loss on the change in fair value of the convertible bond and synthetic warrant liabilities and by the amortization of the day 1 loss on the Company’s currently outstanding convertible bond for an amount of €1.5 million. This compares to a net negative financial result of €2.1 million for the six months ended June 30, 2025.

Nyxoah realized a net loss of €48.9 million for the six months ended June 30, 2026, compared to a net loss of €43.0 million for the six months ended June 30, 2025.

Cash and cash equivalents

On June 30, 2026, cash and cash equivalents and financial assets totaled €97.8 million, compared to €48.0 million on December 31, 2025. The increase in financial assets is due to an equity raise completed in the second quarter of 2026 and the draw down of the second tranche of the Company’s term loan facility.

3.2026 OUTLOOK

The Company expects to continue ramping up sales primarily in the United States. In markets where we are already present such as Germany, Switzerland, the United Kingdom and the Middle East, and in other select international markets, we strive for further growth subject to the receipt of favourable reimbursement for the Company’s product in those markets.

4.RISK FACTORS

We refer to the description of risk factors in the Company’s 2025 annual report, pp. 81-101. 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, the outcome of intellectual property litigation, our organization and operations.

NYXOAH SA

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. 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.

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.

Nyxoah SA has established 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) and 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 June 30, 2026 and for the three and six months ended June 30, 2026, have been authorized for issue on August 5, 2026 by the Board of Directors of the Company.

2.Material 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, 2025.

Except for the application of standards, interpretations and amendments being mandatory as of January 1, 2026, 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, 2025.

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

Table of Contents

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, 2025.

Going concern principle

The Unaudited Interim Condensed Consolidated Financial Statements have been prepared under the assumption of going concern. As of June 30, 2026, the Company held cash and cash equivalents totaling €64.1 million and financial assets amounting to €33.7 million. Based on projected cash flows for the remainder of 2026 and into 2027, management believes this liquidity position is adequate to cover capital needs and sustain operations for at least 12 months from the date of authorization of these financial statements.

The Company confirms that despite the conflict between Israel and Iran, operations are continuing with no major impact and the assets are currently safeguarded. The Company is not suffering impact of this conflict.

New and amended standards and interpretations applicable

Effective for the annual periods beginning on January 1, 2026

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

The following amendment applies for the first time in 2026, but does not have an impact on the interim condensed consolidated financial statements of the Company:

-Amendments to IFRS 9 and IFRS 7 Classification and Measurement of Financial Instruments

-Annual Improvements – Volume 11

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 5.5.2 from the Group’s 2025 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

Financial assets

Cash guarantees are recorded in the consolidated statement of financial position under “Other long-term receivables”. Upon release of the guarantees, interest is received for the duration of the guarantee, whereby the carrying amount approximates the fair value.

The prepayment option, recorded in the consolidated statement of financial position under “Other long-term receivables”, related to the loan facility agreement with the European Investment Bank (“EIB”), is measured at fair value through profit and loss (see note 18.2).

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

The foreign currency forwards and swaps, recorded in the consolidated statement of financial position under “Other receivables”, are measured at fair value through profit and loss. Fair value is determined by the financial institution and is based on foreign currency swap rates and the maturity of the instrument. Refer to note 23.

Financial liabilities

The loan facility agreement with the EIB, recorded in the consolidated statement of financial position under “Financial debt”, is measured at amortized cost with a fixed interest rate. Refer to note 18.2. The fair value is evaluated based on the interest rates and maturity date. The instrument has a fixed interest rate and the fair value measurement is subject to changes in interest rates. The fair value measurement is classified as level 3.

The synthetic warrants, in connection with the loan facility agreement with the EIB and recorded in the consolidated statement of financial position under “Financial debt”, are measured at fair value through profit and loss (see note 18.2). The fair value is determined using a binomial tree with 240 monthly periods (20 years) and the following key unobservable input:

Volatility of 65.144%, estimated based on the median of the annualized 90 - day standard deviation of daily volatility of Nasdaq stock prices over the period from July 2023 to June 2026.

A 5% increase in volatility for Tranche A would result in an increase in fair value by €70,000, while a 5% decrease in volatility would result in a decrease in fair value by €81,000.

A 5% increase in volatility for Tranche B would result in an increase in fair value by €65,000, while a 5% decrease in volatility would result in a decrease in fair value by €76,000.

The convertible bonds, recorded in the consolidated statement of financial position under “Financial debt”, are measured at fair value through profit and loss (see note 18.3). The fair value is determined using the Longstaff-Schwartz Monte Carlo valuation model. We refer to note 18.3 for the overview of the key assumptions. A 5% increase in volatility would result in an increase in fair value by €0.8 million, while a 5% decrease in volatility would result in a decrease in fair value by €0.8 million. A 1% increase in credit spread would result in a decrease in fair value by €158,000, while a 1% decrease in credit spread would result in an increase in fair value by €164,000.

The carrying value of trade and other liabilities approximates their fair value due to the short-term character of these instruments. The sensitivity on the fair value measurements of the recoverable cash advances are further detailed in note 18.1.

Table of Contents

There were no changes in the Group’s valuation processes, valuation techniques, and types of inputs used in the fair value measurements during the period. There were no transfers between level 1 and level 2 fair value measurements during the period and no transfers into or out of level 3 fair value measurements.

The total acquisitions for the six months ended June 30, 2026 amount to €2.0 million (2025: €0.8 million).

The main part of the acquisitions for the six months ended June 30, 2026 relate to leasehold improvements under construction.

The R&D tax incentive recorded as at June 30, 2026 relates to investments both on tangible and intangible assets for the years 2022 until 2026. The incentives are expected to be received 5 years after the investments are made. However, following the Law of May 12, 2024 (Belgian Gazette May 29, 2024), the Belgian R&D tax credit regime has been amended. As of 2024, the R&D tax incentive will be refunded after 4 years instead of 5 years. We refer to note 24.

The increase of €2.7 million in trade receivables, contract assets and other receivables is mainly due to an increase in trade receivables by €1.6 million, an increase in other by €1.2 million and an increase in advance payments by €357,000. This is partly offset by a decrease in current tax receivable by €314,000. The increase in trade receivables is the result of an increase in quarter over quarter revenue.

The Company can 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, 2025 and June 30, 2026, there were no unbilled receivables towards customers included in the other receivables. As at June 30, 2026, the increase of €1.2 million in other receivables is related to an invoicing in the context of a lease agreement for the cleanroom project described in note 7.

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

We refer to note 23 for more details on the foreign currency swaps and forwards.

On June 26, 2026, the Company reduced the exercise price of the outstanding warrants previously granted to warrant holders under all Warrants Plans to 1.53 EUR to reflect the decrease in the company’s share price. 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 (June 26, 2026). 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 in P&L at date of modification. The expense for the original option grant will continue to be recognised as if the terms had not been modified.

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

Equity-settled share-based payment transactions – Restricted Stock Units (“RSU”)

In 2024, 2025 and 2026, each non-executive director was granted “restricted share units” or “RSUs”, whereby each RSU represents the obligation of the relevant non-executive director to subscribe for one new ordinary share of the Company at a subscription price of EUR 0.1718 per share (irrespective of the market value of the share at that time).

The RSUs will be accounted for as an equity-settled share-based payment plan as the Company can issue new shares under the authorized capital.

At June 12, 2024, the Company has granted a total of 103,642 RSUs towards 7 directors which vested at the shareholders’ meeting held in June 2025. As at June 30, 2026 all RSUs had been exercised.

At June 11, 2025, the Company has granted a total of 146,531 RSUs, with the same conditions as the 2024 RSUs, towards 7 directors which vested at the shareholders’ meeting held in June 2026. As at June 30, 2026 all RSUs had been exercised.

At June 10, 2026, the Company has granted a total of 358,267 RSUs, with the same conditions as the 2024 RSUs, towards 7 directors which will vest at the shareholders’ meeting held in June 2027. The total RSUs outstanding as at June 30, 2026 was 358,267 RSUs.

A sensitivity analysis of the carrying amount of recoverable cash advances has been done to assess the impact of a change in assumptions. The Company tested reasonable sensitivity to changes in revenue projections of +/- 25% and in the discount rates of +/- 25%. The table hereunder details the sensitivity results:

Fair Value of Liabilities (in EUR 000)

Variation of revenue projections

*

A change of -25% in the discount rates implies that the discount rate used for the fixed part of the recoverable cash advances is 3.8% instead of 5% while the one used for the variable part is 9.4% instead of 12.5%.

An increase of 25% of revenue projections implies, if discount rates does not change, an increase of the expected liability as repayment of the liability is accelerated.

An increase of 25% of the discount rate decreases the expected liability if revenue projections remain unchanged.

18.2.   Financial debt related to loan facility agreement and synthetic warrants agreement

On July 3, 2024 the Company has signed a €37.5 million loan facility agreement with the European Investment Bank (“EIB”). The agreement is backed by the European Commission’s InvestEU program. The Company plans to use the funding for research and development, and for scaling-up its manufacturing capacity to meet demand in Europe and the U.S. The €37.5 million facility is divided into three tranches: €10 million for the first tranche (“Tranche A”), €13.75 million for the second tranche (“Tranche B”) and €13.75 million for the third tranche (“Tranche C”). Disbursement under the various tranches is subject to certain conditions. The various tranches do not contain revenue or liquidity covenants.

21

Table of Contents

The first tranche A for an amount of €10 million, was disbursed on July 26, 2024. Tranche A carries an annual 5% cash and 5% capitalized interest rate, and features a five-year bullet repayment schedule.

The second tranche B for an amount of €13.75 million, was disbursed on June 17, 2026. Tranche B carries an annual 4% cash and 4% capitalized interest rate, and features a five-year bullet repayment schedule.

In connection with the loan facility agreement, and as a condition to drawdown thereunder, the Company also entered into a “synthetic warrant agreement” with the EIB. Under the synthetic warrant agreement, in consideration for the facility, in connection with each tranche of the facility, the EIB will be granted “synthetic warrants” with a duration of 20 years. The number and strike price of the synthetic warrants will be calculated based on tranche specific formulas provided for in the synthetic warrant agreement. The synthetic warrants can be exercised as of the maturity date of the relevant tranche of the facility or, in exceptional situations, earlier. Such synthetic warrants will entitle the EIB to receive from the Company a cash consideration equal to the 20-day volume weighted average price of a share in the Company on the stock exchange, reduced by the applicable strike price per synthetic warrant, and multiplied by the number of synthetic warrants that the EIB exercises. In connection with Tranche A, the EIB has been granted 468,384 synthetic warrants with a strike price of €8,54 that the EIB can exercise after the maturity of Tranche A (5 years) or, in exceptional situations, earlier. On June 12, 2026, as an anti-dilution protection, the number of synthetic warrants have increased to 2,702,703 and the strike price has decreased to €1.48. In connection with Tranche B, the EIB has been granted 2,101,492 synthetic warrants with a strike price of €2,01 that the EIB can exercise after the maturity of Tranche B (5 years) or, in exceptional situations, earlier.

18.3.   Financial debt related to Convertible Bond Instrument

On November 13, 2025, the Company entered into a bond subscription agreement with an international financial services firm for the issuance of a Convertible Bond Instrument for an aggregate maximum principal amount of up to €45 million. The financing consists of a first tranche of 225 Convertible Bond Instruments up to €22.5 million with an option to issue a second tranche of another 225 Convertible Bond Instruments of up to €22.5 million at the Company’s discretion, within the period commencing 7 months following the first tranche closing date to (but excluding) the date falling one month thereafter. The closing for the first tranche of the Convertible Bond Instruments occurred on December 18, 2025 and will mature on November 18, 2028 (“First Tranche”). The First Tranche carry an interest rate of 6.5 per cent per annum, payable every quarter in arrears. The initial principal amount per Bond Instruments amounts to €100.000. The Bond Instruments have a three-year maturity from issuance with quarterly amortization payments of principal and interest (per 18 February, 18 May, 18 August and 18 November of each year). On each instalment date, the principal instalment per Bond Instrument will be €8.500 except for the last instalment which will be €6.500 per bond. The initial conversion price for the first tranche of bonds, which can be modified, shall be equal to €5.00. On June 9, 2026, as an anti-dilution protection, the conversion price has been reset to €1.48.

The Bond Instrument is accounted for as a hybrid financial instrument containing a host financial liability with embedded derivatives that are closely related (Deferred amortized payment) and embedded derivatives that are not closely related (Bond conversion right, Amortization conversion right, Share settlement option and Advanced amortized payment). The entire hybrid contract is designated by management at fair value through profit and loss. The fair value of the hybrid contract is estimated using a Longstaff–Schwartz Monte Carlo approach, in which share prices are simulated forward on a weekly basis over a 36-month horizon, with each instalment date treated as a decision point. At maturity, the model computes the terminal payoff, after which the valuation is performed by working backwards through time: at each decision point, the continuation value (i.e., the expected value of waiting rather than exercising) is obtained by discounting the value from the next decision point and is then estimated via regression on the simulated state variables. The model compares the immediate exercise value with the regression-based expected continuation value to determine the optimal exercising strategy, assuming exercise occurs whenever the value of exercising now exceeds the expected value of waiting, and the resulting optimal exercise strategy is used to derive the Bond Instruments’ fair value.

The valuation model is dependent on the following significant inputs:

The expected volatility has been estimated based on the historical share prices of the Company on Euronext (as this is the primary stock exchange as determined in the Bond Subscription Agreement). The discount rate is determined based on a risk-free interest rate, based on the 3-month Euribor rate, plus a credit spread estimated for the Company based on the previous debt instruments and factors such as financial results, liquidity needs that may impact the credit spread of the Company.

The transaction price of the Bond Instrument at initial recognition is the consideration of the first tranche for €22.5 million. The difference between the transaction price and the fair value at initial recognition is considered a ‘day 1’ loss, amounting to €8.7 million, which is recognized in profit and loss on a systematic straight line basis throughout the term of the Bond Instrument.

Per March 2, 2026, the Company has converted the first principal instalment of €1.9 million and accrued interest for €246,000 into shares at a conversion price which was 90% of the share price at instalment date. Refer to note 16.

Per May 20, 2026, the Company has converted the second principal instalment of €1.9 million and accrued interest for €335,000 into shares at a conversion price which was 90% of the share price at instalment date. Refer to note 16.

The fair value loss for the six months ended June 30, 2026 is mainly resulting from the conversion price reset per June 9, 2026, partly mitigated by the decrease in stock price in 2026. Refer to note 27.

The Company has a constructive obligation related to the ongoing replenishment of certain consumable components, based on business practices and customer expectations.

On May 30, 2025, the Company was sued in the U.S. District Court of Delaware by Inspire Medical, Inc. (“Inspire”) for the alleged infringement of 3 Inspire patents (US Patent Nos: 10,898,709, 11,806,526, and 11,850,424). The complaint requests customary remedies for patent infringement, including (i) a judgment that the Company has infringed and is infringing the Inspire Patents, (ii) damages, (iii) attorneys’ fees, (iv) a permanent injunction preventing the Company from infringing the Inspire Patents and (v) costs and expenses. The Company subsequently engaged counsel to represent the Company in this case. The Company intends to vigorously defend itself against the allegations brought forward in the Inspire complaint.

On September 15, 2025, the Company has filed a lawsuit against Inspire in the U.S. District Court of Delaware for the alleged infringement of 3 Nyxoah patents (US Patent Nos: 8,700,183, 9,415,215, and 9,415,216). The complaint requests customary remedies for patent infringement, including (i) a judgment that Inspire has infringed and is infringing the Nyxoah Patents, (ii) damages, (iii) attorneys’ fees, (iv) a permanent injunction preventing Inspire from infringing the Company’s patents and (v) costs and expenses.

Given the early stage of this litigation, the Company is unable to predict the likelihood of success of the Inspire claims against the Company or to quantify any risk of loss. Therefore, the Company has not accrued for any potential litigation losses as of June 30, 2026. Legal costs incurred in connection with this matter have been accrued through June 30, 2026, and are recognized in the Selling, General

and Administrative Expense on the line item “Legal fees”. The company reviews the status of the litigation each quarter going forward for accrual purposes.

For the six months ended June 30, 2026, the current tax expense mainly relates to (i) an increase of income tax payable by certain of the Company’s subsidiaries for an amount of0.6 million (2025: €286,000), and (ii) an additional accrual of the liability for uncertain tax positions for an amount of €254,000 (2025: €121,000).

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. The current tax liability of 4.0 million mainly relates to a liability for uncertain tax positions for an amount of €3.7 million.

The decrease by €707,000 in other liabilities as at June 30, 2026, compared to December 31, 2025, is mainly due to a decrease by €1.0 million in payroll related liabilities. The decrease is partly offset by an increase of €0.6 million in accrued expenses and €203,000 in other.

As at June 30, 2026, Other mainly consists of an outstanding liability related to the continued development of the Company’s strategic R&D project.

23.Foreign currency swaps and forwards

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 and forwards. There have not been any transfers of level 3 categories during the year.

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

Before capitalization of €154,000  for the six months ended June 30, 2026 and €1.6 million for the six months ended June 30, 2025, research and development expenses decreased by €2.1 million or 10.2 %, from €20.6 million for the six months ended June 30, 2025, to €18.5 million for the six months ended June 30, 2026. The decrease is mainly due to a decrease in clinical study expenses and in R&D activities. Additionally, following FDA approval in August 2025 and the finalization of one of the clinical studies in April 2026, the amortization of the related intangible assets commenced leading to an increase in depreciation and amortization expense.

Research and development expenses decreased by €1.2 million or 11.2%, from €10.8 million before capitalization of €0.7 million for the three months ended June 30, 2025, to €9.5 million for the three months ended June 30, 2026, due to a decrease in clinical study expenses and in R&D activities.

The financial income decreased from €5.5 million for the six month period ended June 30, 2025 to €2.5 million for the six month period ended June 30, 2026. This decrease can mainly be explained by a decrease in interest by €1.2 million, decrease in exchange differences by €0.7 million, decrease in fair value adjustment on synthetic warrants by €0.5 million and decrease in fair value adjustment on foreign currency swaps and forwards by €493,000.

For the six month period ended June 30, 2026, exchange gains amount to €2.2 million which consists of €0.8 million realized exchange gains and €1.4 million unrealized gains. The unrealized exchange result is mainly related to the revaluation of both the Company’s USD cash balance and USD financial assets.

The Company holds both EUR and USD balances, each used to settle expenses in their respective currencies.

While the Company does hedge a few transactions using swap contracts, the Company does not apply hedge accounting. The swap instruments are short-term and mainly used to manage transactional exposures in GBP, ILS, and CHF. Although GBP sales are expected to cover GBP costs going forward, some contracts have been used to address short-term needs. In addition, a few swaps were used to neutralize the currency impact of our USD-denominated T-bills, which were purchased using EUR balances for convenience, in line with the portfolio allocation approved by the board.

The main contributor to the exchange gain is explained by the fact that the majority of the cash held by the Belgian subsidiary is held in USD to cover future USD expenses. As a result, the recent depreciation of the euro, approximately 3.0 % between January 1 and June 30, 2026, has led to a unrealized FX gain upon translation of USD cash to the functional currency of the subsidiary which is EUR.

For the six month period ended June 30, 2026, total interest income amounted to €250,000 (three month period ended June 30, 2026: €82,000). This interest income relates to the term accounts. The decrease can be explained by a decrease in number of term accounts contracted by the Company.

The financial expenses increased from €7.6 million for the six month period ended June 30, 2025 to €9.4 million for the six month period ended June 30, 2026 mainly due to an increase in fair value adjustment of the convertible bond by €2.6 million, amortization day 1 loss convertible bond €1.5 million, fair value adjustment synthetic warrants by €2.8 million partially offset by a decrease in exchange differences by €5.1 million.

The exchange losses amounting to €1.0 million for the six month period ended June 30, 2026 which consist of €489,000 realized exchange losses and €0.5 million unrealized exchange losses. The unrealized exchange result is mainly relate to the revaluation of both the Company’s USD cash balance and USD financial assets.

The discounting impact of the recoverable cash advances is further detailed in note 18 above.

The fair value adjustments the prepayment option are related to the EIB loan facility agreement. More information can be found in note 18.2.

More information on the amortization of the day 1 loss related to the convertible bond can be found in note 18.3.

28.Earnings/ (Loss) Per Share (EPS)

The Basic Earnings Per Share and the Diluted Earnings Per Share are calculated by dividing earnings for the year by the weighted average number of shares outstanding during the year. As the Company is incurring net losses, outstanding warrants have no dilutive effect. As such, there is no difference between the Basic and Diluted EPS.
