Outlook

The Company remains upbeat about the progress made to date in 2024 and intends to capitalise on positive recent developments in the U.S., following the publishing of the EPA PFAS Drinking Water regulations, as it continues to aggressively pursue partnerships, pilots, data collection and projects in its core markets. There is tremendous opportunity in the EOR market for the REGEN product. The Company is engaged with multiple producers who require better performance during production for EOR and beneficial reuse. Both the PFAS and REGEN offerings are designed to be best in class in their applications and the Company expects to see a continued uptick in demand for sales and/or pilot projects from globally recognisable firms over the rest of 2024.

Connie Mixon, CEO, commented:

"During 2023, MYCELX delivered steady progress in its core areas of focus. This can be seen with the number of new project awards and recurring work agreed during the period. We believe we have tremendous upside with differentiated technology that provides clear economic and environmental benefits that will result in significant growth for the Company into the future.

I would like to take the time to thank the Board and the enthusiastic team at MYCELX for their hard work and dedication during 2023, in what was a period of change for our business. Post the sale of our Saudi business operations, we sit as a leaner, better capitalised company, focused on significant opportunities within our reach and we look forward to updating our stakeholders on further developments in the coming months."

1 EBITDA is a non-U.S. GAAP measure that the Company uses to measure and monitor performance and liquidity and is calculated as net profit before interest expense, provision for income taxes, and depreciation and amortisation of fixed and intangible assets, including depreciation of leased equipment which is included in cost of goods sold. This non-U.S. GAAP measure may not be directly comparable to other similarly titled measures used by other companies and may have limited use as an analytical tool.

Chairman's Statement

Throughout 2023, MYCELX made considerable progress in strengthening its market leading position as clean water technology experts. Against a dynamic global economic backdrop, MYCELX's international customers have continued their strong demand for cost-effective solutions that both optimise their operations and help them achieve their ever-important sustainability goals.

Over the course of 2023, and into 2024, MYCELX continued to develop and hone its strategy and offerings, reflecting the evolving needs of its customers and ensuring it is best placed to capitalise on growing market opportunities.

MYCELX refined its strategic focus by divesting (post period end) its business operations in Saudi Arabia. This allows the Company to better focus on, and invest in, its core PFAS and REGEN offerings, both of which are highly attractive opportunities for the Company. Following this divesture, MYCELX has a more targeted strategy in two large, high-margin markets, which the Board believes have the potential to create significant value for shareholders. With these positive changes in its business portfolio, MYCELX still retains a clear and common purpose to improve the ESG performance of industry and to achieve cleaner water around the world. Furthermore, the Board firmly believes this will provide access to fast-growing markets for the Company's proven technology, while also providing diversification in terms of products, customers and geographies.

MYCELX is well placed to play a key role in the PFAS remediation industry, which is increasingly recognised as an unprecedented health and environmental challenge and therefore a major market opportunity. In the U.S., new Government regulations and funding will positively impact PFAS remediation market demand. MYCELX's internationally recognised solution is vital in combating the widespread risks to human health posed by PFAS-contaminated water. The total global PFAS remediation market is estimated to be in excess of $250 billion, and we believe that early moving companies such as MYCELX, with patented, proven solutions, are well positioned to capture valuable share in this large and growing market.

The Company continues to make progress with its REGEN offering, which targets water treatment in the EOR market and other specialty remediation segments of the oil and gas sector. MYCELX's patent-protected REGEN solution has been successfully deployed with multiple leading oil and gas companies, and the Company hopes to build on this success to secure more business going forward. MYCELX believes that these markets will remain attractive for the foreseeable future, and will likely play a role in unlocking new, attractive opportunities in the oil and gas sector.

Underpinned by world leading, patented technologies, MYCELX has adapted to evolving markets and has positioned itself to deliver long-term value for all shareholders by capitalising on its two main market offerings - PFAS and REGEN. This is an exciting time for MYCELX, not only in terms of helping its customers meet their essential environmental commitments, but also for the continued growth of the Company.

Finally, I would like to thank our shareholders for their continued support, as well as the outstanding, committed employees at MYCELX for their unwavering efforts to capitalise on the attractive opportunities in our targeted markets.

Chief Executive Officer's Statement

During 2023, MYCELX delivered steady progress in its core areas of focus. This can be seen with the number of new project awards and recurring work agreed during the period.

In terms of agreements signed, they included a significant REGEN project award in the EOR sector in the Middle East that has positive, long-term implications for widespread REGEN media adoption. We were also awarded our fourth in-country project, valued at $5.4 million, with a National Oil Company deploying REGEN for onshore produced water treatment.

We also made notable progress in the PFAS remediation market with pilot trials initiated in the United States, equipment and media sales and trials in Australia, receiving national health and safety accreditation for our PFAS product and forging relationships with potential strategic partners, which led to multiple, ongoing discussions throughout the year continuing into 2024. Our downstream operations in Saudi Arabia received three new contracts and renewed two existing contracts. During the year, the Company also began negotiations to sell its business operations in Saudi Arabia and transition it into an exclusive distributorship. The Board believed this approach was in the best interest for all stakeholders, and post period end, the operation was bought by a Saudi Arabian consortium with strong relationships in-country and the ability to expand into new markets with MYCELX technology. We look forward to supporting the new owners and the country's Vision 2030 initiatives with which our advanced water treatment products are very well aligned to.

The PFAS remediation market in the United States, and elsewhere in the world, continues to develop as regulations are being issued to address the magnitude of the problem and as public awareness increases through global media exposure. It is a market opportunity in which we are highly engaged with proven technology that we intend to capitalise on. The size of the market continues to grow as more PFAS-contaminated sites continue to be identified. Effective, efficient technology is essential to clean up PFAS contamination in the challenging applications and equally necessary is the ability to scale technology cost effectively, which is one of the important differentiators that sets us apart when compared with our peers.

Oil and gas markets were, and continue to be, robust, with producers globally planning upgrades and expansion of existing fields. We continue to see the trend of greater adoption of cleaner production solutions, while operators increase production, all of which have high commercial value with clear environmental benefits. Our REGEN product achieves those goals. The EOR and beneficial reuse markets are our focus as well as offshore production. Each one of these areas of oil and gas production offer tremendous opportunity for global adoption of our REGEN media product.

Operational Highlights

PFAS Remediation

MYCELX has chosen to target four markets in the PFAS sector: landfill leachate, municipal drinking water, residential use and industrial wastewater. In 2023, MYCELX installed a pilot system at a landfill leachate site working with a global engineering company and began the process of identifying a pre-treatment system to prevent fouling of the MYCELX system and PFAS removal media. The pre-treatment project has continued into Q2 2024 and, if successful, should lead to further project work with the lead engineering company in the leachate application. In the municipal drinking water sector, the Company received National Sanitation Foundation (NSF) 61 certification, a national health and safety stamp-of-approval required for filtration media that will be used to treat drinking water. The media was also tested and found compliant with the Toxic Characteristic Leaching Procedure (TCLP) that certified our PFAS media product does not leach specific PFAS chemicals at levels that exceed the regulatory limits. This benefits the business in waste disposal, given the captured PFAS will not re-enter the environment after coming in contact with our PFAS media. During the year, our Business Development Director held multiple meetings with potential strategic partners in each market vertical we are targeting. We know that many technologies, including the incumbent carbon and resin media, have gaps in performance that MYCELX PFAS media can address. It has provided an opening to work with several domestic and global partners who recognise the benefits of integrating our technology as an effective solution and for MYCELX to leverage pre-treatment technologies as well.

Post period, the Company won a short-term project treating water contaminated with AFFF firefighting foam. Working with a global engineering company, MYCELX has been able to showcase the performance of our solution in a common application that can be replicated at many AFFF-contaminated sites. Our aim is to continue this application in additional AFFF-contaminated sites and potentially become their go-to solution for AFFF remediation. In the municipal wastewater market, the Company tested PFAS-laden water samples from a wastewater treatment plant that is trialling several technologies they chose for potential implementation. After third-party lab verification of MYCELX PFAS removal capability, the Company was chosen as one of the technologies to be tested on-site for the trial which will commence in Q1 2025. The outcome of the trial will determine the lucrative project award expected to be announced in later 2025. After a long search for an experienced PFAS technical expert, MYCELX brought onboard a professional with nine years of PFAS experience from a global water equipment and solutions provider. The PFAS market is very large, lucrative and in need of new technology. We intend to break into the four markets we have identified with a two-fold approach; i) strategic partnerships and ii) distributors who service and sell to customers who need reliable technology and have years of experience in water treatment sales. Recently, the Company sold media to a national residential drinking water company who we intend to partner with to sell our media used in their point-of-entry ('POE') systems to protect homes from PFAS contamination.

As the year progresses, our trials will continue to operate, gathering critical data that will help us refine and optimise our offering and the pre-treatment steps required by some of our systems going forward. We are confident that we will be able to convert trials to revenue-generative projects in 2024 and 2025.

REGEN for Enhanced Oil Recovery and Beneficial Reuse

In our REGEN division, we secured a contract with a National Oil Company ('NOC') for a REGEN system and media valued at $5.4 million with delivery expected in late 2024. This will be our fourth project installation in-country. Our systems ensure discharge into surface water is in compliance with regulations. We believe we will continue to sell our REGEN systems for this application given the increased focus on environmental concerns in the region as well as the proven, superior performance and reliability to meet or exceed discharge regulations. The Company contracted its first project with a NOC in the Middle East to treat water during EOR production. They are replacing their nutshell media with REGEN, based on our unique innovation of a retrofit package that enables their equipment to be modified to accept our REGEN media. This is the first of several projects MYCELX is engaged in with this producer and expects to participate in future projects with others in the region who intend to upgrade to REGEN to increase their production and reduce water consumption. In the U.S., the Company operated successful pilots at mature assets for beneficial reuse of produced water with two U.S. oil and gas producers. Beneficial reuse of water in oil and gas production is being embraced in the U.S. to recycle and reuse water that is scarce in areas where oil is produced. After successful trials and technical acceptance of the REGEN media in 2023, we expect a contract award in 2024 as producers adopt Beneficial Reuse into their production process.

Downstream Middle East

In Saudi Arabia the Company won three new purchase orders and renewed two contracts. Post period end, executing on our strategic plan, we sold our Saudi Arabia business operations to Twarid Water Treatment LLC ('Twarid'), a Saudi Arabian owned consortium, and transitioned the business to a MYCELX exclusive distributorship. The transaction was structured as an Earn Out, with the Company receiving $3.125 million upon closing, with the potential of an additional $4.0 million received based on achieving the revenue targets historically reached over the last several years of operations.

This strategic decision has the potential to be a seminal event for MYCELX. Saudi Arabia has played an important role in the Company's growth and under the leadership of the legacy MYCELX management team in the region and Twarid's strong relationships, we believe that this distributorship has the potential to significantly accelerate the growth of our existing media business in addition to unlocking significant upside potential in oil and gas, petrochemicals, industrial wastewater, PFAS remediation and marine applications. Although MYCELX will no longer be involved in the ongoing operations in-country, this has significant benefits to the business, as it reduces our cost base, increases personnel bandwidth for executing plans in our two other core markets, and allows us to support Twarid as they increase market share and grow media sales in one of the largest and most robust water-scarce countries in the world.

The sale leaves the Company in a stronger financial position, and as ever, we continue to adopt a strict capital allocation policy, ensuring that our costs are as low as possible, while ensuring adequate money is being invested in the growth of the business.

The decision also enables us to focus on what we believe are the Company's two largest market opportunities - PFAS remediation and EOR REGEN. The size of the prize in both of these markets is significant and we believe that focusing on these two very large opportunities will provide the Company with high-margin, long-term revenue for decades to come.

Following our progress in recent years, we believe we have laid the foundations to achieve further market penetration with our REGEN offering in the U.S. onshore oil and gas sector. As we have seen over the last 12 months, significant consolidation has occurred, with now only a handful of players possessing dominant positions in key areas such as the Permian Basin. We have successfully trialled in the Permian with major players and expect to move to a contract in 2024 provided the project progresses on schedule.

Given our track record in the U.S., we know we have the technology to assist operators with their water handling needs, and we believe that with there now being a more concentrated number of operators, we have a strong opportunity to increase our market presence. MYCELX technology has been proven across a wide range of applications to deliver operational efficiencies, cost savings and better environmental solutions to customers.

We have made a strong start to 2024 and we anticipate MYCELX will achieve revenues in the range of $9.0 to $10.0 million during the year. The Company continues to focus on a number of other potential opportunities which could positively influence 2024 revenue and the final outturn is dependent on projects meeting delivery timelines.

In closing, I would like to take the time to thank the Board and the enthusiastic team at MYCELX for their hard work and dedication during 2023, in what was a period of change for our business. Post the sale of our Saudi business operations, we sit as a leaner, better capitalised company, focused on significant opportunities within our reach.

We believe we have tremendous upside with differentiated technology that provides clear economic and environmental benefits that will result in significant growth for the Company into the future. We look forward to updating our stakeholders on further developments in the coming months.

Financial Review

Due to growth in long-term legacy media sales and a sale of REGEN and a retrofit package to an EOR producer in the Middle East, total revenue increased 9% to $10.9 million for 2023, compared to $10.0 million for 2022. Revenue from equipment sales and leases decreased by 17% to $3.0 million for 2023 (FY22: $3.6 million) and revenue from consumable filtration media and service increased by 23% to $7.9 million (FY22: $6.4 million). Whilst the equipment sales are one-off by nature, there is longevity to the media sales and ongoing lease and service revenues.

Gross profit decreased by 12% to $3.9 million during the year, compared to $4.4 million in 2022, and gross profit margin decreased to 36% (FY22: 44%) due to increases in costs for ancillary services in Saudi Arabia.

Total operating expenses for 2023, including depreciation and amortisation, decreased by 10% to $7.2 million (FY22: $8.0 million). The largest component of operating expenses was selling, general and administrative expenses, which decreased by approximately 11% to $6.7 million (FY22: $7.6 million) due to moving expenses for relocating the Company's office in Georgia in 2022. Depreciation and amortisation within operating expenses increased by 10% to $231,000 (FY22: $210,000).

EBITDA was negative $2.5 million, unchanged from negative $2.5 million in 2022. EBITDA is a non-U.S. GAAP measure that the Company uses to measure and monitor performance and liquidity and is calculated as net profit before interest expense, provision for income taxes, and depreciation and amortisation of fixed and intangible assets, including depreciation of leased equipment which is included in cost of goods sold. This non-U.S. GAAP measure may not be directly comparable to other similarly titled measures used by other companies and may have limited use as an analytical tool.

The Company recorded a loss before tax of $3.3 million in 2023, compared to a loss before tax of $3.6 million in 2022. Basic loss per share was 16 cents in 2023, compared to basic loss per share of 18 cents in the previous year.

As of 31 December 2023, total assets were $10.4 million with the largest assets being inventory of $3.4 million, property and equipment of $2.6 million, $1.8 million of accounts receivable and $433,000 of cash and cash equivalents including restricted cash.

Total liabilities as of 31 December 2023 were $3.4 million and stockholders' equity was $7.2 million, resulting in a debt-to-equity ratio of 47%.

The Company ended the period with $433,000 of cash and cash equivalents, including restricted cash, compared to $1.7 million in total at 31 December 2022. The Company used approximately $1.1 million of cash in operations in 2023 (FY22: $2.7 million used in operations) and $180,000 was used in investing activities (FY22: $840,000 used in investing activities). Proceeds from the Placing of Common Shares contributed $2.0 million provided by financing activities in FY22.

Post period end, the Company sold its Saudi Arabia business operations, including equipment, inventory and contracts, for an acquisition price of up to $7.125 million (the 'Total Consideration') to Twarid Water Treatment LLC ('Twarid'). The Total Consideration was split $3.125 million at closing with up to $4 million deferred on a 24 month earn-out structure based on Twarid achieving defined revenue targets. The assets sold had a net book value of $2.2 million. The proceeds of the sale will enable the Company to focus on accelerating its marketing and sales plan for its unique technologies in the PFAS remediation and EOR markets while continuing to grow its propriety media and product sales in Saudi Arabia through an exclusive distribution agreement with Twarid.

Notes to the Financial Statements

Nature of Business and Basis of Presentation

Basis of presentation - These financial statements have been prepared using recognition and measurement principles of Generally Accepted Accounting Principles in the United States of America ('U.S. GAAP').

Nature of business - MYCELX Technologies Corporation ('MYCELX' or the 'Company') was incorporated in the State of Georgia on 24 March 1994. The Company is headquartered in Norcross, Georgia with operations in Houston, Texas, Saudi Arabia and the United Kingdom. The Company provides clean water technology equipment and related services to the oil and gas, power, marine and heavy manufacturing sectors and the majority of its revenue is derived from the Middle East and the United States.

Liquidity - The Company meets its day-to-day working capital and other cash flow requirements through cash flow from operations. Post period end, the Company sold its Saudi Arabia business operations for $7.125 million which included $3.125 at closing and up to $4 million deferred on a 24 month earn-out structure. The proceeds of the sale will enable the Company to focus on accelerating its marketing and sales plan for its unique technologies in the PFAS remediation and EOR markets while also supporting other working capital needs. The Company actively manages its financial risk by operating Board-approved financial policies that are designed to ensure that the Company maintains an adequate level of liquidity and effectively mitigates financial risks.

On the basis of current financial projections, including a downside scenario sensitivity analysis considering only revenues that are contracted or that the Company considers probable and adjusting for direct cost of goods sold within the analysis, the Company believes that it has adequate resources to continue in operational existence for the foreseeable future of at least 12 months from the date of the issuance of these financial statements and, accordingly, consider it appropriate to adopt the going concern basis in preparing these Financial Statements. Should the projected cash flow not materialise under certain scenarios, alternative actions to increase liquidity may need to be considered.

Summary of Significant Accounting Policies

Revenue from filtration media sales and spare parts (part of equipment sales) is billed and recognised when products are shipped to the customer. Revenue from equipment leases is recognised over time as the equipment is available for customer use and is typically billed monthly. Revenue from professional services provided to monitor and operate the equipment is recognised over time when the service is provided and is typically billed monthly. Revenue from turnkey projects whereby the Company is asked to manage the water filtration process end to end is recognised on a straight-line basis over time as the performance obligation, in the context of the contract, is a stand-ready obligation to filter all water provided. Revenue from contracts related to construction of equipment is recognised upon either factory acceptance testing or shipment of the equipment to the customer because the control transfers at acceptance or the point of shipment and there is no enforceable right to payments made as customer deposits prior to that date. Customer deposits for equipment sales represent payments made prior to transferring control at the point of shipment that can be refunded at any time when requested by the customer.

The Company's contracts with customers often include promises to transfer multiple products and services. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgement. Judgement is required to determine stand-alone selling price ('SSP') for each distinct performance obligation. The Company develops observable SSP by reference to stand-alone sales for identical or similar items to similarly situated customers at prices within a sufficiently narrow range.

Unbilled accounts receivable represents revenue recognised in excess of amounts billed. Contract liability represents billings in excess of revenue recognised. Unbilled accounts receivable at 31 December 2023 and 2022, and 1 January 2022 was $255,000, $nil and $175,000, respectively. Contract liability at 31 December 2023 and 2022, and 1 January 2022 was $nil, $nil and $54,000, respectively.

During the years ended 31 December 2023 and 2022, the Company did not have any costs to obtain a contract and any costs to fulfil a contract were inconsequential.

Cash, cash equivalents and restricted cash - Cash and cash equivalents consist of short-term, highly liquid investments which are readily convertible into cash within ninety days of purchase. At 31 December 2023, all of the Company's cash, cash equivalent and restricted cash balances were held in checking and money market accounts. The Company maintains its cash in bank deposit accounts which, at times, may exceed federally insured limits. At 31 December 2023 and 2022, cash in non-U.S. institutions was $92,000 and $159,000, respectively. The Company has not experienced any losses in such accounts. The Company classifies as restricted cash all cash whose use is limited by contractual provisions. At 31 December 2023, restricted cash included $50,000 in a money market account to secure the Company's corporate credit card. At 31 December 2022, restricted cash included $84,000 in a money market account to secure the Company's corporate credit card and a stand-by letter of credit.

Reconciliation of cash, cash equivalents and restricted cash at 31 December 2023 and 2022:

Accounts receivable - Trade accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company provides credit in the normal course of business to its customers and performs ongoing credit evaluations of those customers and maintains allowances for doubtful accounts, as necessary. Accounts are considered past due based on the contractual terms of the transaction. Credit losses, when realised, have been within the range of the Company's expectations and, historically, have not been significant. The allowance for doubtful accounts at 31 December 2023 and 2022 was $208,000 and $168,000, respectively.

Inventories - Inventories consist primarily of raw materials and filter media finished goods as well as equipment to house the filter media and are stated at the lower of cost or net realisable value. Equipment that is in the process of being constructed for sale or lease to customers is also included in inventory (work-in-progress). The Company applies the Average Cost method to account for its inventory. Manufacturing work-in-progress and finished products inventory include all direct costs, such as labour and materials, and those indirect costs which are related to production, such as indirect labour, rents, supplies, repairs and depreciation costs. A valuation reserve is recorded for slow-moving or obsolete inventory items to reduce the cost of inventory to its net realisable value. The Company determines the valuation by evaluating expected future usage as compared to its past history of utilisation and future expectations of usage. At 31 December 2023 and 2022, the Company had REGEN-related inventory of 44 percent and 41 percent of the total inventory balance, respectively, which is in excess of the Company's current requirements based on the recent level of sales. The inventory is associated with efforts to expand into the Enhanced Oil Recovery and Beneficial Reuse markets that the Company has identified as large global markets. These efforts should reduce this inventory to desired levels over the near term and management believes no loss will be incurred on its disposition. However, there is a risk that management will sustain a loss on the value of the inventory before it is sold. No estimate can be made of a range of amounts of loss that are reasonably possible should the efforts not be successful.

Impairment of long-lived assets - Long-lived assets to be held and used, including property and equipment and intangible assets with definite useful lives, are assessed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset, a loss, if any, is recognised for the difference between the fair value and carrying value of the assets. Impairment analyses, when performed, are based on the Company's business and technology strategy, management's views of growth rates for the Company's business, anticipated future economic and regulatory conditions, and expected technological availability. For purposes of recognition and measurement, the Company groups its long-lived assets at the lowest level for which there are identifiable cash flows, which are largely independent of the cash flows of other assets and liabilities. No impairment charges were recorded in the years ended 31 December 2023 and 2022.

Research and development costs - Research and development costs are expensed as incurred. Research and development expense for the years ended 31 December 2023 and 2022 was approximately $248,000 and $218,000, respectively.

Advertising costs - The Company expenses advertising costs as incurred. Advertising expense for the years ended 31 December 2023 and 2022 was $9,000 and $nil, respectively, and is recorded in selling, general and administrative expenses.

Income taxes - The provision for income taxes for annual periods is determined using the asset and liability method, under which deferred tax assets and liabilities are calculated based on the temporary differences between the financial statement carrying amounts and income tax bases of assets and liabilities using currently enacted tax rates. The deferred tax assets are recorded net of a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of the recorded deferred tax assets will not be realised in future periods. Decreases to the valuation allowance are recorded as reductions to the provision for income taxes and increases to the valuation allowance result in additional provision for income taxes. The realisation of the deferred tax assets, net of a valuation allowance, is primarily dependent on the ability to generate taxable income. A change in the Company's estimate of future taxable income may require an addition or reduction to the valuation allowance.

The Company recognises interest accrued related to tax in interest expense and penalties in selling, general and administrative expenses. During the years ended 31 December 2023 and 2022 the Company recognised no interest or penalties.

Earnings per share - Basic earnings per share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common and potentially dilutive shares outstanding during the period. Potentially dilutive shares consist of the incremental common shares issuable upon conversion of the exercise of common stock options. Potentially dilutive shares are excluded from the computation if their effect is anti-dilutive. Total common stock equivalents consisting of unexercised stock options that were excluded from computing diluted net loss per share were approximately 1,903,694 for the year ended 31 December 2023 and there were no adjustments to net income available to stockholders as recorded on the Statement of Operations.

Years Ended 31 December

The three levels of the fair value hierarchy under ASC 820 are described below:

• Level 3: Unobservable inputs for the asset or liability.

There were no transfers into and out of each level of the fair value hierarchy for assets measured at fair value for the years ended 31 December 2023 or 2022.

All transfers are recognised by the Company at the end of each reporting period.

The Company's financial instruments as of 31 December 2023 and 2022 include cash and cash equivalents, restricted cash, accounts receivable and accounts payable. The carrying values of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term nature of those assets and liabilities.

Recently issued accounting standards - In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires measurement and recognition of expected credit losses for financial assets held. The standard is to be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company adopted this guidance effective 1 January 2023. The adoption of this new guidance did not have a material impact on the financial statements.

• Related Party Transactions
• Segment and Geographic Information

ASC 280-10, Disclosures About Segments of an Enterprise and Related Information, establishes standards for reporting information about operating segments. ASC 280-10 requires that the Company report financial and descriptive information about its reportable operating segments. Operating segments are components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker ('CODM') in deciding how to allocate resources and in assessing performance. The Company's CODM is the Chief Executive Officer ('CEO'). While the CEO is apprised of a variety of financial metrics and information, the business is principally managed on an aggregate basis as of 31 December 2023. For the year ended 31 December 2023, the Company's revenues were generated primarily in the Middle East and the United States ('U.S.'). Additionally, the majority of the Company's expenditures and personnel either directly supported its efforts in the Middle East and the U.S., or cannot be specifically attributed to a geography. Therefore, the Company has only one reportable operating segment.

Revenue from customers by geography is as follows:

Long-lived assets, net of depreciation, by geography is as follows:

In general, these events are recognised in the financial statements if the conditions existed at the date of the Balance Sheet, but are not recognised if the conditions did not exist at the balance sheet date. Management has evaluated subsequent events through 15 May 2024, the date the financial statements were available to be issued, and no events have occurred which require further disclosure other than the following:

On 29 February 2024, the Company sold its Saudi Arabia business operations, including equipment, inventory and contracts, for an acquisition price of up to $7.125 million (the 'Total Consideration') to Twarid Water Treatment LLC ('Twarid').
