A year of continued progress

NIOX is the market leader in point of care FeNO testing for the diagnosis and management of asthma. The NIOX VERO® device is approved and reimbursed in most major markets. FeNO testing rates increased in most major markets as COVID-19 related restrictions were lifted and more patients visited their physicians in person.

2023 saw both strong growth in sales and adjusted EBITDA as a result of disciplined execution of the strategy.

Revenues for the year ended 31 December 2023 were up 18% to £36.8 million (2022: £31.3 million), and up 22% on a constant currency basis. Pleasingly, the year ended having achieved a 31.0% adjusted EBITDA margin (2022: 23.3%) driven by revenue growth and the benefits of outsourcing sales and manufacturing.

NIOX experienced strong demand in the Clinical business (sales to physicians and hospitals for use in clinical practice) which grew by 24% versus 2022 and 29% on a constant currency basis.

APAC clinical sales demonstrated the strongest recovery and grew by 42% versus 2022 on a constant currency basis. Japan, the strongest Asia Pacific market, is our largest market and ended the year with sales 57% higher than 2022 in constant currency terms. This was fuelled in the first half by a post-COVID-19 recovery in FeNO testing and in the second half by broadening the penetration of NIOX® devices into new clinics.

EMEA clinical sales experienced strong growth of 27% versus 2022 on a constant currency basis. The UK is the largest European market driven by continued uptake of FeNO testing in Primary Care. Growth in Spain and Germany were also strong contributors to the EMEA region's performance.

The Americas region grew by 12% on a constant currency basis (compared with previous year growth of 7%). Management made significant changes to the US commercial organisation and distributor network in 2023 with the objective of ensuring that FeNO testing and NIOX reach their considerable full potential in the USA, moving forward.

Research sales for the year (sales generated from contract research organisations (CROs) conducting clinical studies on behalf of pharmaceutical companies) fell by 18% (14% on a constant currency basis). The size of the Research market is driven by the number of clinical trials being conducted at any given time, which is wholly determined by the research pipeline of pharmaceutical companies and is thus outside the control of NIOX. This means that year to year comparisons can fluctuate dependent upon the timing and number of clinical trials involving FeNO testing in a given year.

The Group's strategy of focussing on accelerating the growth of FeNO testing in Primary Care, where most asthmatics are treated, remains unchanged. Third party distributor arrangements are a key enabler of this strategy and have the benefit of not adding fixed costs to the business.

Asthma is one of the biggest healthcare challenges in the world; there are over 340 million asthma sufferers worldwide and this is forecast to grow to more than 400 million by the end of the decade. Asthma causes the loss of 1,000 lives every day and many more suffer asthma attacks that result in emergency call outs and hospital admissions.

To help address these challenges, establishing FeNO testing and NIOX® for asthma diagnosis and management in Primary Care is top priority. Healthcare systems are increasingly seeking strategies to care for patients in non-clinic settings and at home. With this in mind, the Company plans to introduce FeNO testing in other healthcare channels such a pharmacies and occupational health and ultimately to introduce a product for use by patients to manage their condition at home.

Group expenditure (excluding depreciation, amortisation and share option charge) increased slightly to £15.1 million (2022: £14.9 million). Group headcount remained unchanged at 92.

Management expects costs to increase marginally above inflation in 2024 due to investment into the US market. Headcount is also expected to increase slightly during the year.

Discontinued operations

The transfer of the COPD products back to AstraZeneca completed on 31 March 2021. An operating profit of £1.2 million was generated by this business in 2023 as the rebate and returns accrual was revised down based on claims received during the year and forward-looking assumptions as to the value of claims expected to be received in future financial periods.

NIOX retains legal liability for rebates payable to third parties (primarily Medicaid) and for return of products sold during the period during which it operated the COPD business. NIOX's liability for returns will have been extinguished by 30 April 2024.

The cash outflow during the year for rebates and returns totalled £2.0 million (2022: £nil). Remaining accruals related to the discontinued COPD business were £0.9 million as at 31 December 2023 (2022: £4.6 million).

Russia and Ukraine

NIOX has no operations in Russia and generates no revenue in Russia. In 2023, revenues derived from Ukraine were less than 1% of Group revenues.

Energy prices and inflation

The Group has two strategic manufacturing partners and does not manufacture its own products. The effect of inflationary pressures on purchase prices from its two main suppliers is mitigated both by the Group's high gross margins and its ability to implement price increases in most of its markets. Accordingly, the substantial increase in energy prices has not had a material impact on the Group's operations.

Beyond Air

As a result of Beyond Air, Inc. ("Beyond Air") receiving approval from the U.S. Food and Drug Administration (FDA) for its LungFit® PH device, the Group is entitled to receive payments of $10.5 million in total, in three instalments as follows:

·      $2.5 million within 60 days of the approval of LungFit® by the FDA ("FDA approval"), which was received on 24 August 2022;

·      $3.5 million within 60 days of the first anniversary of FDA approval, which was received on 25 August 2023; and

·      $4.5 million within 60 days of the second anniversary of FDA approval, which is due in August 2024.

In addition, the Group is entitled to a royalty of 5% of net sales of the device, commencing on the second anniversary of FDA approval and capped at a maximum of $6 million. These royalties have not been recognised due to uncertainties around quantum and timing.

Investments

The Group has commenced development of its new NIOX Pro® device. This device will offer improved ergonomics, a larger screen and improved iOS and Android connectivity. It will be fully compatible with existing test kits.

Development costs totalling £0.2 million have been capitalised to date in accordance with the requirements of accounting standards. The aggregate development costs of the NIOX Pro®, including tooling, should not exceed £2.0 million, with the bulk of these costs being incurred in 2024.

During 2024, we expect to incur approximately £0.2 million on preliminary research and development work associated with a home use device.

Employees

On behalf of the Board, I would like to thank all employees within the Group for their hard work and commitment.

Board Changes

Jo LeCouilliard will not offer herself for re-election at the forthcoming AGM. Jo has been a Non-Executive Director (and Chair of the Audit and Risk Committee) for six years and I would like to thank her for her significant contribution during that time. A replacement will be announced in due course, and until that time Garry Watts will, in addition to his role as Senior Independent Director, take over as Chair of the Audit and Risk Committee.

Michael Roller, Chief Financial Officer, has agreed with the Board that he will reduce his time commitment to the Group to three days per week with effect from 1 April 2024.  Michael is supported by a strong team including the Group's Financial Controller and Company Secretary and the Group Operating Finance Director.

Summary and outlook

2023 was another good year for the Group. The results demonstrate the clear ability of our business model to generate profitable growth.

Management is continuing to implement a growth strategy that will raise the awareness of the benefits of FeNO testing and significantly improve the availability of NIOX® worldwide by expanding distribution, optimising reimbursement, and improving patient access. As first steps on the journey to home FeNO testing, the Company plans to make NIOX® available in pharmacies and through occupational health organisations.

The business has made a positive start to 2024 and the Board expects another year of solid progress.

Key strategic drivers of the Group

The opportunity

Asthma affects over 340 million people worldwide with a further 100 million estimated to be affected by 2025. There are an estimated 1,000 deaths globally due to asthma every day. In 50% of cases, asthma is either not diagnosed or is misdiagnosed, which leads to a delay in asthma patients receiving the care that they need. Following a diagnosis of asthma, it is important to be able to regularly monitor the condition to confirm the effectiveness of treatment and adherence by the patient.

In 2023 NIOX, the clear market leader in FeNO testing worldwide, sold approximately five million tests.

FeNO

Asthma is a condition that is characterised by inflammation of the airways and lungs. Nitric oxide is produced by inflammatory cells and can be precisely measured in exhaled breath, this is known as FeNO (fraction of exhaled nitric oxide). Measuring FeNO helps medical professionals to understand the level of inflammation in the lungs of an asthmatic and is a precise biomarker of type 2 airway inflammation. FeNO measurements can improve the chances of a correct diagnosis by up to seven times.

The American Thoracic Society (ATS) recommended that FeNO testing should be part of the ongoing care of asthmatics as well as being used as a tool for diagnosing asthma. This is the latest example from an increasing body of highly credible, influential evidence based medical guidelines around the world that have recommended the use of FeNO testing as a routine part of diagnosing and managing asthma. The guidelines are based on a substantial body of published clinical trials that demonstrate the benefits of FeNO testing. Measuring FeNO as part of ongoing asthma management has been shown to decrease asthma exacerbations by 50%.

Further impetus is coming from a new class of biologic anti-inflammatory medicines for the treatment of type 2 inflammatory asthma. Biologic medicines are targeted at asthmatics with increased inflammation and therefore elevated FeNO. The cost of these new medicines is significant. This means that some pharmaceutical companies are investing resources to raise the awareness and usage of FeNO testing in order to identify the patients that are most likely to respond to treatment as they seek to establish this new class of drugs as an effective line of therapy.

Our products

The Company's NIOX VERO® is the market leading device for measuring FeNO. This is a non-invasive, point-of-care system which accurately measures the patient's FeNO level. It is quick, easy to use and reliable. The system comprises a small portable device and a range of consumables including sensors, individual disposable mouthpieces and breathing handles. The quality and innovation of NIOX VERO® has been recognised with several awards over recent years, including the 2022 Research and Development Award and 2023 Best Asthma Diagnosis and Management Company.

NIOX® is registered and reimbursed in all major markets and available in more than 50 countries via NIOX's international network of distribution partners.

Our business

NIOX VERO® is the market leading device for FeNO testing with more than 50 million FeNO tests sold to date.

NIOX® revenues in 2023 for clinical diagnosis and management of asthma were £32.6 million (2022: £26.2 million). Approximately 90% of these revenues are from recurring sales of consumables used for routine testing.

Revenues in 2023 from CROs were £4.2 million (2022: £5.1 million). A lower proportion of these revenues are from sales of consumables as clinical trial sales are for a defined time period and are typically on a one-time sale basis.

Principal challenges

Today the awareness and usage of FeNO testing and NIOX® amongst the respiratory specialist community is relatively high. The majority of asthmatics are under the care of Primary Care doctors, where the awareness and usage of FeNO is significantly lower than the specialist community. This means that there is huge untapped potential in the FeNO testing market. The primary challenge the NIOX® business faces is to increase the awareness and usage of FeNO testing, specifically in the Primary Care customer group.

The Company continues to engage with respiratory professionals to promote the use of FeNO tests in new and under-served customer segments such as primary care settings and pharmacies which provide a significant opportunity for the Group.

Conclusion

The Company's mission is to improve asthma diagnosis and management by greater patient access to FeNO testing. The Group has a robust strategy in place to expand the business and generate profitable growth from this large underserved market and has the financial resources to achieve its objectives.

FINANCIAL REVIEW

This has been a year of continued growth for NIOX. The level of FeNO testing carried out by our customers increased, resulting in higher revenues and adjusted EBITDA, which the Group considers to be key KPI's.

¹ Earnings before interest, tax, depreciation, amortisation and share option charge.

² On 9 April 2020, the Group announced that that the development and commercialisation agreement with AstraZeneca was terminating and as such the results of the COPD business are classified as a discontinued operation.

Revenue

NIOX® revenues for the year were £36.8 million (2022: £31.3 million). NIOX® clinical revenue of £32.6 million (2022: £26.2 million) represents sales to physicians and hospitals for use in clinical practice and to the Company's distributors. NIOX® research revenue of £4.2 million (2022: £5.1 million) is from pharmaceutical companies and contract research organisations (CROs) for use in clinical studies.

A significant part of the growth in NIOX® revenues was attributable to an increase in testing volumes to more normal levels in Japan and China as COVID-19 related restrictions were removed in these countries. There was also good growth in Europe, in particular the UK and Germany, due to greater focus on increasing the awareness of FeNO testing.

Gross profit

Gross profit on NIOX® revenue was £26.5 million (2022: £22.2 million), with a gross margin of 72% (2022: 71%). Gross margin was higher than the prior period mainly due to product mix. In the year there was a greater proportion of higher margin test kit sales and a reduced proportion of lower margin, device heavy research sales.

Research and development

Research and development costs decreased to £2.3 million (2022: £3.2 million). Included in this category are, £0.2 million of Quality costs (2022: £0.3 million), £0.2 million of Regulatory costs (2022: £0.3 million), £0.1 million of Medical Affairs costs (2022: £0.3 million), £nil Device Development costs (2022: £0.4 million) and £1.8 million of depreciation and amortisation (2022: £1.9 million). The decrease in costs is mainly attributable to lower headcount, particularly in the Device Development department. The development of the new NIOX Pro® device has been outsourced to our manufacturing partner and the costs meeting the eligibility criteria will be capitalised. In the current year, £0.2 million was capitalised.

Sales and marketing

Sales and marketing costs increased to £11.2 million (2022: £9.7 million). Costs were higher in the current year mainly on account of a strategic realignment in the US to unlock the full sales potential in both the clinical and research businesses, which has increased headcount. Additionally, global marketing activities are returning to normal levels following the COVID-19 pandemic.

Administrative expenditure

Administrative expenditure, which includes overheads relating to corporate functions, centrally managed support functions and corporate costs, increased to £8.4 million (2022: £7.5 million). This was mainly attributable to a higher share option charge.

Other income

Other income has decreased to £0.2 million (2022: £8.3 million). The current year figure includes £0.2 million (2022: £0.2 million) of sub-lease rental income relating to the Chicago office, which ends in February 2024. The prior period figure includes £8.1 million relating to the one-off recognition of the settlement consideration due from Beyond Air.

Taxation

Taxation for the year was a credit of £5.4 million (2022: £3.6 million). The deferred tax asset recognised in respect of carried trading losses increased due to improved expectations regarding future financial performance.

Earnings per share

Basic earnings per share for the year was 2.55p (2022: 3.84p) and diluted earnings per share for the year was 2.38p (2022: 3.63p) reflecting a profit after tax of £10.7 million (2022: £16.1 million). The decrease in reported earnings per share is largely due to the recognition of the full consideration due from Beyond Air in the prior period.

Excluding the impact of depreciation, amortisation, share option charge and the one-off Beyond Air consideration, adjusted basic earnings per share from continuing operations for the year was 3.87p (2022: 2.73p). See note 9.

Basic earnings per share from continuing operations was 2.26p (2022: 3.36p) and diluted earnings per share for the year was 2.11p (2022: 3.19p) reflecting a profit from continuing operations for the financial year of £9.5 million (2022: £14.1 million).

Profit from discontinued operations

A profit of £1.2 million (2022: £2.0 million) was generated by discontinued operations in the year as the rebate and returns accrual was revised down based on claims received and forward-looking assumptions as to the value of claims expected to be received in future financial periods.

Statement of financial position

The Group's net assets at 31 December 2023 were £83.8 million (2022: £81.9 million).

Current liabilities at the end of the year were £7.2 million (2022: £9.2 million). The decrease is mainly due to lower trade payables, in particular lower accruals relating to discontinued operations, as £2.0 million of invoices were settled with AstraZeneca in the period.

Share premium reduced significantly to £0.1 million as at 31 December 2023 (2022: £640.3 million). During the year, a Capital Reduction Scheme was concluded by filing an order of the High Court with the Registrar of Companies. This resulted in the share premium of the Company being cancelled.

Other comprehensive expense

The Group's other comprehensive expense of £0.2 million (2022: £1.9 million) relates to exchange differences on the translation of foreign operations into British pound sterling.

The current year expense is mainly due to the strengthening of the British pound against the Swedish krona. It was offset by a £0.5 million (2022: £0.7 million) adjustment to record the net gain on foreign exchange translation on certain intercompany balances through other comprehensive income. During the year, a number of long-term intercompany balances were designated as being in the nature of long-term-investments and as such the associated foreign exchange translation gain was removed from the income statement.

Cash flow

The Group's cash position (including cash and cash equivalents) increased from £19.4 million at 31 December 2022 to £19.9 million at 31 December 2023.

Cash generated from operations during the year amounted to £11.7 million (2022: £6.9 million). Included in this was £2.0 million (2022: £nil) used in the COPD discontinued operations and £2.8 million (2022: £2.0 million) received from Beyond Air under the terms of the relevant settlement agreement.

A special dividend totalling £10.5 million (2022: £nil) was paid to shareholders.

Exchange differences on cash and cash equivalents arose as a result of translation of foreign currency balances at the beginning and end of the relevant period. The exchange loss for the period was £0.3 million (2022: £0.7 million gain).

Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

2.     Operating segments

The chief operating decision-maker, the Executive Chairman, examines the Group's performance from a product perspective, and has identified one reportable segment in the continuing business:

-       NIOX® relates to the portfolio of products used to improve asthma diagnosis and management by measuring fractional exhaled nitric oxide (FeNO).

The COPD business has been classified as a discontinued operation. Information about the results of this segment is provided in note 7; information regarding its assets is presented below.

The table below presents operating profit/ (loss) information regarding the Group's operating segments for the years ended 31 December 2023 and 2022. Only the results for the Group's continuing activities are included in order to aid comparison.

 Segment operating profit/ (loss)

Assets by segment

3.     Employees and directors

Monthly average number of people (including Executive and Non-Executive Directors) employed:

The Group's total headcount at 31 December 2023 was 92 (2022: 92).

Employee benefit costs

Key management personnel

Key management personnel during the year included directors (Executive and Non-Executive), Regional VP APAC, Senior VP Americas and Research, VP Supply Chain and Technical Operations, Regional VP EMEA, and Senior VP Global Human Resources. Key management personnel in the prior year included the VP of Product Development. The compensation paid or payable to key management is set out below.

4.     Breakdown of expenses by nature

5.     Other income

Beyond Air was granted FDA approval of the LungFit® PH product on 28 June 2022, and therefore other income and a corresponding receivable was recognised for the total consideration of $10.5 million (£8.1 million). The consideration was measured by discounting the asset to its present value, with the unwinding of the discount recognised as finance income.

6.     Finance costs and income

7.     Discontinued operations

On 9 April 2020, an agreement was signed to hand back the Tudorza® and Duaklir® licences to AstraZeneca and as such, the results of the COPD operating segment are reported as a discontinued operation. There were no assets or liabilities classified as held for sale in relation to the discontinued operation.

Revenue relates to a revision of the rebate accrual based on information and claims received during the year and forward-looking assumptions as to the value of claims expected to be received in future financial period.

The cash outflow relates to the settlement of certain contractual liabilities relating principally to rebates and returns, which were accrued for at the time the business was discontinued.

Remaining accruals related to the discontinued operation totalled £0.9 million at 31 December 2023 (31 December 2022: £4.6 million).

8.     Taxation

The tax credit (2022: credit) for the year is lower (2022: lower) than the standard rate of corporation tax in the UK of 23.52% (2022: 19.00%). The differences are explained below:

In the Spring Budget 2021, the UK Government announced that from 1 April 2023 the corporation tax rate would increase to 25% (rather than remaining at 19%, as previously enacted). This new law was substantively enacted on 24 May 2021. For the financial year ended 31 December 2023, the current weighted averaged tax rate was 23.52%.

Deferred taxes at the balance sheet date are measured using the substantially enacted tax rates in the relevant jurisdictions in which the Group operates.

At 31 December 2023, the Group has tax losses to be carried forward of approximately £491.0 million (2022: £510.4 million). These can be utilised against future taxable profits with no restrictions, except as stated below. A proportion of these tax losses has been recognised as a deferred tax asset.

NIOX Group plc and NIOX Healthcare Limited had tax losses to be carried forward of approximately £169.4 million (2022: £163.2 million). These losses have no expiry date, however, the utilisation of these losses will be restricted to 50% of profits in excess of £5.0 million generated in the United Kingdom.

NIOX Inc. had federal tax losses to be carried forward of approximately £123.1 million (2022: £129.4 million). Federal losses generated after 1 January 2018 have no expiry date, however, the utilisation of these losses will be restricted to 80% of profits generated in the United States. Federal losses generated before 1 January 2018 expire after 20 years.

NIOX Inc. also had state losses to be carried forward of approximately £82.4 million (2022: £87.2 million) which have been generated across multiple states and have a range of expiry periods from 5 to 20 years.

9.     Earnings per share

The earnings used in calculating basic and diluted earnings per share is the same.

Adjusted basic earnings per share eliminates depreciation, amortisation, share option charge and the impact of the Beyond Air settlement consideration. The prior year signed financial statements only excluded the impact of the Beyond Air settlement consideration. The comparatives have been restated.

10.          Goodwill

The carrying value of goodwill is allocated to the NIOX® CGU and was generated in June 2015 on the acquisition of Aerocrine.

The recoverable amount of a CGU is assessed using a value in use model. The value in use for the NIOX® CGU was calculated over a five-year period using a discount factor of 12.7% (being a weighted average cost of capital rate for the CGU). The calculations use post-tax cash flow projections. Cash flows over five years have been considered appropriate based on the product lifecycle. Cash flows beyond the five-year period were extrapolated using the estimated terminal growth rate stated below. The growth rate does not exceed the long-term average growth rate for the business.
