We are substantially dependent on revenue generated from services related to our integrated enterprise management software, including monthly subscription fees

Our revenue is substantially dependent on our integrated enterprise retail management software licensing and ongoing services related to them. The significant majority of our revenue is derived from the monthly subscription fees for the use of our software, which comprise almost all of our gross operating revenue (89.1%, 86.8%, 89.8% and 89.6% for the three-month period ended March 31, 2019, and for the years ended December 31, 2018, 2017 and 2016, respectively). As a result, a reduction in revenue from this source, whether due to increased competition, adverse market conditions or a general reduction in demand for integrated enterprise management software and services or other factors, could materially adversely affect our operational results, cash flows and liquidity.

The software industry is highly competitive and we may be unable to compete effectively

We compete in markets characterized by vigorous competition, changing technology, changing client and end-consumer needs, evolving industry standards and frequent introductions of new products and services. We compete with several companies that operate in the global, regional and local software industries, including providers of integrated enterprise management software, developers of free software, payment processing and companies providing consulting services and outsourcing. Some of our current or potential competitors may be engaged in a greater range of businesses, have a larger installed base of customers for their existing products and services or have greater financial, technical, sales or other resources than us. We expect competition to intensify in the future as traditional, non-traditional and new competitors introduce new services or enhance existing services. We may lose market share if our competitors introduce or acquire new products that compete with our software and related services or add new features to their products or if new entrants emerge in the market. Any of these events could cause a material adverse effect on our business, financial condition, results of operation or cash flows.

Our success depends on our ability to develop new products and services, integrate acquired products and services, improve our existing products and services and keep up with technological developments

The market in which we operate is characterized by constant technological advances, changing hardware requirements, rapid development in software and communications infrastructure, increasingly complex customer requirements and frequent introductions of new products and improvements of existing products. If we fail to improve our products and services to accommodate such technological evolution, as well as any corresponding legislative changes, including changes to tax legislation, in a timely manner or to position and price our products and services to meet market demand, our customers may stop purchasing new software licenses and services from us and we may lose our ability to attract and retain customers.

In addition, internet and network protocols and other industry standards are subject to rapid change and we cannot guarantee that the industry standards that we adopt in developing new products will enable us to compete effectively for new business opportunities in the markets in which we operate. Any of these events could materially adversely affect our revenue and cash generation.

We may experience difficulties in achieving our acquisition strategy

We have acquired, and may from time to time acquire, businesses, products, services and technologies. The success of an acquisition or investment will depend on our ability to make accurate assumptions regarding the valuation, operations, growth potential, integration and other factors related to that business. Our acquisitions or investments may not produce the results that we expect at the time we enter into or complete a given transaction. The risks that we may face in connection with these acquisitions include the following:

We may spend time and capital on acquisitions that do not increase our revenue. To the extent we pay the purchase price of any acquisition in cash, any such purchase would reduce our cash reserves, and to the extent the purchase price is paid with any of our shares, could be dilutive to our shareholders. To the extent we pay the purchase price with proceeds from the incurrence of debt, any such purchase would increase our level of indebtedness and could negatively affect our liquidity, restrict our operations and materially adversely affect our results of operations. Our competitors may be willing or able to pay more than us for acquisitions, which may cause us to be unable to take advantage of certain acquisition opportunities.

The occurrence of any of these events could materially adversely affect our business, operational results, financial condition or cash flow, especially with respect to a large acquisition or several concurrent acquisitions.

We are subject to risks and liability relating to system failures, the non-authorized or incorrect use of third-party data used by and/or made available to our systems

Our systems may receive third-party data. Our efforts to protect such data used by and/or made available to our systems may be insufficient and may not ensure that we are in compliance with applicable rules and regulations related to the collection, treatment and use of users’ data. Any non-compliance with applicable laws may subject us to penalties, such as fines, particularly in relation to (1) the express consent of users for the collection and treatment of their data, (2) the term provided by law for storing and excluding users’ data and (3) the adoption of the required security standards for the conservation and protection of the collected and stored data. Accordingly, the incorrect use of third-party data in our systems and/or the lack of measures to protect such data may (1) result in significant costs to us and the reallocation of our resources and (2) divert the attention of our management and technology team, which may adversely affect our business, competitive position, financial situation, results of operations and cash flows.

Additionally, we retain billing data, intellectual property, personally identifiable information and other sensitive information from our customers on our networks. Our infrastructure and the third-party infrastructure we use to host our solutions may be vulnerable to hacker attacks or other problems, which may overcome the security measures we adopt. In particular, our cloud infrastructure may be vulnerable to security breaches, computer viruses or similar problems, and these systems are also subject to telecommunications failures, power loss and other system failures. Unimpeded access to the cloud servers is fundamental to the provision of services to our SaaS customers. Any of these occurrences, whether intentional or accidental, could lead to interruptions, delays or suspension of our SaaS data center operations and may compromise the information stored on our networks. Such an occurrence could materially adversely affect our reputation as a reliable supplier and host of such solutions and negatively affect the market perception of the safety or reliability of our products or services and, as to SaaS, may cause some of our customers to cancel their subscriptions to our cloud applications and subject us to indemnification payments.

Sales to our customers are made through systems that we have developed, and in the case of our cloud-based solutions, stored on our servers. Any interruption in the operation of these systems may result in a loss of sales from our customers. Furthermore, any error in billing or in issuing the invoice or accounting products sold by our customers could result in substantial losses to them, which could materially adversely affect our results of operations, financial condition and our reputation.

A failure to adequately protect personal data may materially adversely affect us

We manage and maintain the personal data of our customers, employees and suppliers in the normal course of our business. Unauthorized disclosures or security breaches may subject us to legal action and penalties that may materially adversely us. In addition, in the course of our business activities, we are exposed to possible risks of noncompliance with policies, improper conduct of our employees or negligence and fraud, which may result in serious reputational or financial damage.

Currently, the processing of personal data in Brazil is regulated by a diverse and complex body of legislation. Our efforts to protect personal data that we process may not guarantee the adequate protection of such data or compliance with the personal data protection rules established under the current legislative regime.

The Brazilian General Data Protection Act (Federal Law 13,790/2018) was published in the Federal Official Gazette on August 15, 2018 and was amended by Provisional Measure No. 869, issued by the President of Brazil in December 2018, or the MP 869/2018. As amended by the MP 869/2018, the Brazilian General Data Protection Act will take effect in August 2020. This legislation is expected to transform the current legislative regime applicable to personal data protection in Brazil. The Brazilian General Data Protection Act establishes a new legal framework for the processing of personal data and provides for the rights of holders of personal data, legal standards applicable to the protection of personal data, requirements for obtaining consent, obligations and requirements related to security incidents, data leaks and data transfers, as well as the creation of a national data protection authority. We may face difficulties in complying with the Brazilian General Data Protection Act due to the quantity and complexity of the new obligations it will introduce. In the event of non-compliance with the General Data Protection Law, we may be subject to penalties including warnings, the requirement to remove personal data from our system and fines of up to two percent of our economic group’s total most-recently reported annual net revenue and up to a maximum of R$50.0 million per infraction.

The absence of sufficient measures to protect the personal data processed by us, or our inability to comply with applicable legislation, may materially adversely affect us

We depend on suppliers of telecommunications, internet and data centers for our “software-as-a-service,” or SaaS, cloud and on-premise infrastructure, and any fluctuation or interruption in the provision of these services may materially adversely affect our abilities to serve our customers and profitability

Providers of telecommunications, internet and data centers are a fundamental part of our infrastructure of SaaS, cloud and on-premise software and services. We depend on them to provide such services and they constitute a key element in our business strategy and infrastructure. It is crucial that the infrastructure that we use to host our software products remains safe, does not suffer system failures and is perceived by our customers and partners to be safe and reliable. Instability or interruptions of our services due to failures by our suppliers are usually perceived by our customers as our responsibility and may adversely affect the market’s perception of the quality of our products or services, including with respect to SaaS, cloud and on-premise software and services, which may cause some of our customers to cancel their subscriptions to our services and affect our ability to increase our sales.

Our investments in research and development may not result in increased revenue

The investment in the development of software products through research-driven product development and expansion of our knowledge base is costly and may not provide financial returns. Additionally, products with accelerated releases or with short life cycles require high levels of spending on research and development. We believe that we must continue to dedicate a significant amount of resources for research and development to maintain our competitive position. Our investments in research and development may not prove efficient and may not result in increased revenue or growth and, consequently, our financial condition and results of operations could be materially adversely affected. For additional information regarding our investments in research and development, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Capital Expenditures.”

Our growth depends on the continued contributions of certain key members of senior management and our ability to continue to attract and retain qualified personnel

Our performance depends on the efforts and capabilities of certain key members of senior management who are responsible for making most of the critical decisions that guide our business, particularly regarding the implementation of our strategies and development of our operations. If we lose any of these executives, for any reason, we may have problems in defining and executing our business strategy and our financial condition and results of operations could be materially adversely affected.

In addition, if any key members of our senior management leave our company for any reason, we may incur significant costs to attract new highly qualified professionals as replacements. There is significant competition in the global market for qualified personnel in the commercial, technical and other areas. Consequently, we may be required to pay higher compensation in order to attract and maintain qualified personnel, which may adversely affect our operating and financial results.

We are subject to partial or total failures or interruptions in our services and software related to IT infrastructure, which is highly complex

We require a highly complex technology infrastructure for our operations and depend on the efficient and uninterrupted operation of numerous systems, including our computer systems, software, data centers and telecommunications networks, as well as the systems of third parties. We are subject to partial or total failures or interruptions in our services and software that could give rise to loss of revenue, loss of customers, possible actions for damages from our customers, additional operating and development costs and diversion of technical and other resources, among others, adversely affecting our reputation among our customers and the markets in which we operate. In addition, depending on the degree of the damage caused, we may be subject to regulatory penalties, such as the loss of certain approvals to operate our software.

We may be subject to errors, delays or failures of security of our products and services

Our software may contain errors or security flaws, especially at the launch of new products or release of new versions of existing products. The errors in our software may affect the ability of our products to work with other hardware or software, as well as delay the development or release of new products or new versions or undermine the reputation of our products in the market. Our systems and operations could suffer damage or interruption from natural disasters, acts of terrorism, power shortages, telecommunications failure, cyberattacks, sabotage, unauthorized entry, computer viruses and physical or electronic break-ins and similar disruptions from unauthorized tampering with our computer systems and data centers, among others. If we experience errors or delays in the launch of new products or new versions of our existing products, we may lose customers or incur opportunity costs, which may have a material adverse effect on our financial condition, cash flows and operational results.

Additionally, errors and security flaws in our software products may expose us to liability for product performance complaints and warranty claims, as well as damage to our reputation, which could impact future sales of our products and services. Moreover, addressing problems and complaints associated with actual or alleged errors or security flaws may require a significant amount of time and attention from our management team, resulting in high costs, which may have a material adverse effect on our business, financial condition and operational results.

As a holding company, we are dependent on dividends and other distributions from our subsidiaries, which we may not receive

As a holding company, our ability to comply with financial obligations and to pay dividends or other distributions to our shareholders and holders of the ADSs in the future will depend on our cash flows and our subsidiaries’ results of operations, as well as the distribution of such results of operations to us in the form of dividends or interest on equity. The amount of any dividends or distributions which may be paid to us from time to time will depend on many factors including, for example: such subsidiaries results of operations and financial condition; limits on dividends under applicable law; its constitutional documents; documents governing any indebtedness; applicability of tax treaties; and other factors which may be outside our control. There is no guarantee that such resources will be actually available to us or sufficient for us to comply with our financial obligations and to pay dividends or other distributions to our shareholders and holders of the ADSs.

If we are unable to properly manage our growth, our results may be adversely affected

We may fail to correctly estimate, qualitatively or quantitatively, the costs and risks associated with our expansion, and can offer no assurance that our systems, procedures, business processes and management controls are sufficient to support the expected rapid expansion of our operations, including expansion to new markets and verticals. We cannot assure you that our current and planned systems, procedures and controls, personnel and third-party relationships will be adequate to support our future operations. In addition, we have entered and may enter into new lines of business that may involve complexities associated with the new products, services and regulations, which could place a strain on our management and operational and financial resources in the future. If we fail to successfully manage growth, our results of operations may be adversely affected.

Certain of our financing agreements contain cross-default clauses

Some of our financing agreements contain cross-default clauses or cross-acceleration clauses. Accordingly, the occurrence of an event of default under one of the contracts governing our outstanding debt could trigger an event of default on other debt or allow the creditors of our other debt to accelerate repayment to become immediately due and payable, which could materially adversely affect the results of our operations, cash availability and the price of our shares.

Additionally, we have entered into credit facilities in which the Brazilian National Economic and Social Development Bank (Banco Nacional de Desenvolvimento Econômico e Social), or BNDES, imposed several restrictions on us, including the need for prior approval from BNDES for: (1) our or our subsidiaries’ direct lending to individuals or entities which may or may not have shared corporate interests with us; (2) borrowing from individuals or entities which have shared corporate interests with us; (3) providing guarantees of any kind in operations with other creditors, in the event the guarantees have not also been provided to BNDES under the same conditions and having the same priority and (4) making investments in companies in Brazil or abroad. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Indebtedness.”

Losses not covered by our insurance policies may have a material adverse effect on us

We are subject to risks for which we do not have adequate or any insurance coverage, including risks not managed by our backup systems and contingency plans. For instance, we have not obtained insurance to protect against cybersecurity risks. Furthermore, the quantification of risk exposure in existing clauses in our insurance policies may be inadequate or insufficient, and may lead to a lower-than-expected insurance repayment. In addition, our insurance policy coverage is conditional on the payment of premiums under such policies. Our failure to pay these premiums together with the occurrence of a claim may put us at risk, as the relevant insurer would not be liable to cover us for any losses we incurred. We cannot assure you that we will be able to maintain our insurance policies in the future or that we will be able to renew them at reasonable prices or on acceptable terms. Thus, if certain damaging events occur and we are not adequately insured against them, they may, individually or together, adversely affect our results of operations and require us to commit significant cash resources to cover such losses. See “Business — Insurance.”

We are subject to unfavorable results in judicial or administrative proceedings that may adversely affect our results and financial condition

We are a party to certain legal and administrative proceedings. Unfavorable decisions in these proceedings may adversely affect our results and financial condition in the event our resulting liability exceeds any amounts we have provisioned or guarantees we have deposited in respect of these proceedings. See “Business — Legal and Administrative Proceedings.”

Any significant interruption in our cloud-based platform could materially adversely affect our business and harm our reputation, forcing us to provide credits or refunds and may cause customers to terminate their contracts with us prior to their stated maturity, which may adversely affect us

Our cloud-based platform is a critical part of our business operations. Any significant interruption in our services, products and/or infrastructure may give rise to claims by our customers, which may negatively affect the results of our operations and our financial condition, as well as our reputation with our customers.

We may suffer losses due to defaults by our customers

A default by one or more of our subscribed customers or by one or more groups of customers, could have a material adverse effect on our business, results of operation, financial condition and cash flows.

Potential interruptions in payment by customers could be caused by a customer’s financial difficulties including bankruptcy, among other factors. In addition, a failure on our part to properly analyze the credit or financial condition of these customers may result in the failure to properly identify and make provisions for default by customers.

Substantially all of our revenues are derived from customers concentrated in the retail sector, which is sensitive to unfavorable economic cycles and decreases in the purchasing power of consumers

Our activities are exclusively focused on the retail sector and substantially all of our revenues are derived therefrom. Historically, the Brazilian retail sector has been prone to periods of economic downturn resulting in an overall decline in consumer spending. The success of retail sector operations depends on several factors relating to consumer spending, including the general business climate at the time, interest rates, inflation, the availability of consumer credit, taxation, consumer confidence in future economic conditions, levels of employment and wages. Unfavorable conditions in the Brazilian economy can therefore significantly reduce consumer spending, which could materially adversely affect our sales, results of operations and financial condition.

We may experience unfavorable conditions in our industry or the global economy that result in reductions in spending on IT that could limit our ability to grow and develop our business, thereby adversely affecting our results of operations

Our results of operations may vary according to the impact of changes in our industry or global economy on us or our customers. Increases in revenue and profitability of our business depend on demand for our software and related services.

In light of the fact that we are a service provider, part of our revenue results from the number of new users of our software, which in turn is influenced by general employment levels. Insofar as unfavorable economic conditions cause our customers and potential customers to merely maintain or even reduce their demand for our services, our revenue may be adversely affected. Historically, economic downturns have resulted in overall reductions in IT spending, as well as pressure for longer billing cycles, as occurred during the recession of 2016. If economic conditions deteriorate or do not improve significantly, our customers and potential customers may choose to reduce their IT solutions, which would limit our ability to expand our business and could materially adversely affect our results of operations.

Our business and results of operations could be harmed if we are unable to protect and enforce our intellectual property rights

Measures we have taken to protect our intellectual property may be inadequate to prevent misappropriation, resulting in the misuse of our products and forcing us to protect our intellectual property through legal or administrative proceedings. The misuse of our products or the measures we are required to take to protect our intellectual property rights could result in substantial costs to us and divert the resources and attention of our management and technical team, which could materially adversely affect our business, competitive position, financial condition, results of operations and cash flows.

We are subject to the risk of lawsuits involving alleged violations of intellectual property rights of third parties, due in part to the recent increase in the number of patents and copyrights by technology companies

We may be required to change, in whole or in part, certain of our products that have allegedly infringed upon the intellectual property rights of third parties and may be required to pay significant amounts of penalties, royalties or licensing fees for the use of others’ patents or copyrighted materials. Any changes to our products or to revenue attributable to any of our products that are in violation of others’ intellectual property rights may materially adversely affect our results of operations, reputation and the demand for our products. In addition, such changes may require attention from our management, cause us to incur additional legal expenses, or in some cases, require us to create reserves, all of which may materially adversely affect us.

We benefit from Brazilian government tax incentive programs, which may be terminated or reduced in the future

We benefit from certain tax incentives related to research and development and technological innovation, established by Law No. 11,196, dated November 21, 2005, as amended, or Lei do Bem, and regulated by Decree No. 5,798, dated June 7, 2006. Our ability to benefit from these incentives depends on our compliance with certain obligations.

Failure on our part to comply with certain obligations in accordance with the applicable rules or to provide the documentation required to substantiate such tax credits could result in the loss of such incentives that have not yet been used and claims by the Brazilian tax authorities of the amount corresponding to taxes not paid as a result of the incentives already used, in addition to penalties and interest under Brazilian tax laws. If any of our tax benefits expires, terminates or is cancelled, we may not be successful in obtaining new tax benefits that are equally favorable, which may materially adversely affect us. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operation — Description of Principal Statement of Income Line Items — Current and Deferred Income Tax and Social Contribution.”

Our business automation software and electronic invoice (Nota Fiscal Electronica), or NFE, services are provided pursuant to approvals by the Brazilian Internal Revenue Service (Secretaria da Fazenda), or Sefaz, of each Brazilian state

We offer business automation software and the use of NFEs and electronic tax receipts (Nota Fiscal Consumidor Electronica), or NFCEs, customized to meet the requirements of the tax laws of different Brazilian states. Such business automation solutions must be approved by the tax authorities of each Brazilian state to certify regulatory adherence. If we do not receive or are at any point denied any of these approvals, we will be prevented from continuing our business automation software and NFEs and NFCEs activities in the state where approval has been denied, which could have a material adverse effect on our financial results.

We or our directors could be accused of facilitating tax evasion by our customers in which case we could be held responsible, along with the customer, for back taxes due to Brazilian tax authorities

In Brazil, enterprise management systems are required to be structured so as not to allow for tax evasion. However, we cannot guarantee that our systems are not susceptible to security breaches that could enable tax evasion by a customer.

If such an event were to occur, Brazilian tax authorities could conclude that our software allows our customers to avoid compliance with their tax obligations and that we had acted in bad faith. Any such conclusion may require us to pay the unpaid taxes of our customers, plus interest and penalties, as well as subject us and our management to civil and criminal liabilities, depending on the magnitude of tax evasion committed by our customer, which could materially adversely affect our results.

The simplification of Brazilian tax rules would reduce the barriers to entry of international competitors

The complexities of Brazilian tax rules largely discourage entry of international competitors into the Brazilian retail market for the software industry, as a strong familiarization of the applicable tax laws of each state and of the Brazilian government is required to function in the sector. The Brazilian government has indicated that it may simplify the tax rules, which would remove an important entry barrier to our foreign competitors and could result in increased competition and materially adversely affect our financial results.

We may experience difficulties in expanding our products or in expanding into new lines of business, industries and/or foreign markets

We may face challenges in connection with the expansion of our products as well as our expansion into new lines of business, industries and/or new geographic regions within or outside of Brazil. In particular, as we expand into new lines of business, such as Linx Pay Hub, we may face challenges associated with entering into a line of business in which we have limited or no experience and in which we may not be well-known. Offering new products and services or offering existing products in new industries or new geographic regions may require substantial expenditures and takes considerable time, and we may not recover our investments in new markets in a timely manner or at all. For example, we may be unable to attract a sufficient number of merchants as customers, fail to anticipate competitive conditions or fail to adapt and tailor our services to different markets.

Currently, we have customers in markets other than Brazil (representing 5.6% of our net operating revenue as of December 31, 2018), and our long-term strategies include further expansion in these markets. We may experience the following difficulties related to the foreign markets in which we currently operate or will operate in the future, among others:

Should one or more of these risks materialize, and we are not able to overcome these difficulties, we may be unable to implement our international expansion strategy.

A decline in the use of credit, debit or prepaid cards as a payment mechanism for consumers or adverse developments with respect to the payment processing industry in general could have a materially adverse effect on revenues which we expect to derive from our new line of business, Linx Pay Hub

If consumers do not continue to use credit, debit or prepaid cards as a payment mechanism for their transactions or if there is a change in the mix of payments between cash, credit, debit, prepaid cards and other accepted method of payments that is adverse to Linx Pay Hub, the revenue we expect to derive from Linx Pay Hub may be materially adversely affected. We believe future growth in the use of credit, debit and prepaid cards and other electronic payments will be driven by the cost, ease-of-use, and quality of services offered to consumers and businesses. In order to consistently increase and maintain our profitability, end-consumers and businesses must continue to use electronic payment methods including, credit, debit and prepaid cards. Moreover, if there is an adverse development in the payments industry or Brazilian market in general, such as new legislation or regulation that makes it more difficult for our merchants to do business or utilize such payment mechanisms, the revenue we expect to derive from Linx Pay Hub may be materially adversely affected.

Furthermore, we pay transaction fees to payment schemes, banks, acquiring payment institutions and other intermediaries that vary according to the method chosen by consumers to fund payment transactions. These transaction fees are higher when consumers fund payments using credit cards, and lower when consumers fund payments with debit cards. The financial success of Linx Pay Hub will be, therefore, sensitive to changes in the proportion of its business funded by consumers using credit and debit cards, which would increase its costs if we are unable to adjust the rates we charge our merchants accordingly.

Brazilian laws, CMN resolutions, circulars promulgated by the Central Bank, as well as future regulations and changes in tax rules affecting the payment industry in Brazil may materially adversely affect us in the event Linx Pay commences merchant acquisition operations

Due to the importance of the payment industry in Brazil, the Central Bank issued several new regulations in 2018 designed to increase the use of electronic payments, increase competitiveness in the sector, strengthen market governance, encourage supply and the differentiation of products for consumers as well as strengthen the use of credit and debit cards as a means of payment. Among the measures taken to effect these changes, the Central Bank issued the following noteworthy circulars:

In addition to existing regulations, the Brazilian congress is currently considering several legislative initiatives that aim to modify the regulatory framework of the electronic payments sector, including changes in the period in which a card issuer makes payment to a commercial establishment and changes in the general rules of the Brazilian National Financial System (Sistema Financeiro Nacional). These initiatives are currently in varying stages of deliberation by the Brazilian congress and create significant uncertainty relating to the regulatory framework we may face in coming years. Brazilian laws, CVM resolutions, circulars or regulations resulting from such initiatives may materially adversely affect us.

We and our independent registered public accounting firm have identified material weaknesses in our internal control over financial reporting and, if we fail to implement and maintain effective internal controls over financial reporting, we may be unable to accurately report our results of operations, meet our reporting obligations or prevent fraud

In connection with the audit of our consolidated financial statements for the year ended December 31, 2018, we and our independent registered public accounting firm identified material weaknesses in our internal controls as noted below:

If we are unable to properly maintain our internal controls, we may not be able to accurately report our financial results or prevent the occurrence of inappropriate or erroneous practices.

Under Section 404 of the Sarbanes-Oxley Act of 2002, our management is not required to assess or report on the effectiveness of our internal control over financial reporting in our annual report on Form 20-F for the fiscal year ending December 31, 2019. We are only required to provide such a report for the fiscal year ending December 31, 2020. At that time, our management may conclude that our internal control over financial reporting is not effective. In addition, until we cease to be an “emerging growth company” as such term is defined in the JOBS Act, which may not be until after five full fiscal years following the date of this offering, our independent registered public accounting firm is not required to attest to and report on the effectiveness of our internal control over financial reporting. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may disagree with our assessment or may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, after we become a public company in the United States, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future. We may be unable to timely complete our evaluation testing and any required remediation.

During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, we may identify other weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002. If we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements, fail to meet our reporting obligations or fail to prevent fraud, which would likely cause investors to lose confidence in our reported financial information. This could, in turn, limit our access to capital markets, harm our results of operations, and lead to a decline in the trading price of the ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the NYSE, regulatory investigations and civil or criminal sanctions.

In the event that Linx Pay commences merchant acquisition operations, it may be subject to losses arising from such operations due to the possibility that credit card issuers default on their obligations to merchant acquirers

While we are currently not a merchant acquirer, we intend to expand our Linx Pay operations into this area in the future. As a merchant acquirer, Linx Pay would be subject to the risk that credit card issuers may default on their obligation to pay Linx Pay the amounts required to complete a cardholder’s transaction and process the corresponding payment to the applicable merchant. Merchant acquirers are also subject to the risk that cardholders may default on their obligations to credit card issuers.

The extent to which Linx Pay, upon commencing merchant acquirer operations, becomes subject to these risks is dependent on the risk/guarantee model that the credit card brand adopts for credit card issuers and credit card holders. Each credit card brand has developed its own model for guarantees that are detailed in its regulations.

Linx Pay may also be exposed to the risk that affiliated sub-merchant acquirers may not pass on the amounts received from us under credit card transactions to their affiliated establishments.

The realization of any of these risks may materially adversely affect our business, results of operations or financial condition.

In the event that Linx Pay commences merchant acquisition operations, our operational results may be adversely affected by fraudulent transactions committed by third parties that are processed by us.

In the event that Linx Pay becomes a merchant acquirer, we will be exposed to the risk of fraudulent transactions carried out by third parties using our credit and debit cards. Failure to effectively manage such risk and prevent fraud may increase our chargeback liability as well as other liabilities and materially adversely affect our business, results of operations or financial condition.

Our customers are charged for the use of certain of our products based on a percentage of the amount they bill to their clients, which may result in seasonal fluctuations that impact our quarterly results of operations.

In recent years, we have experienced seasonal fluctuations in our revenues from the retail sector as a result of consumer spending patterns. Most of our revenues are not tied to the percentage of the amount our customers bill to their clients. Following the launch of our OMS and Linx Pay e-commerce platform, however, we have increased the number of products in our portfolio that generate revenue based on the amount our customers bill their clients. Historically, sales have been stronger during the last quarter of the year as a result of the holiday season in Brazil. This is due to the increase in the number and transaction volumes of digital transactions and electronic payments related to seasonal retail events. With the increase in the aforementioned products as a percentage of our revenue, adverse events that occur during these months may have a disproportionate effect on our results of operations throughout the fiscal year. As a result of quarterly fluctuations caused by these and other factors, comparisons of our results of operations between different fiscal quarters may not be indicative our future performance.

Significant and increasing competition within the payment industry may materially adversely affect us

Linx Pay may face competitive pressure on the fees it charges its clients. Linx Pay’s competitors have already achieved a significant share of the markets in which Linx Pay operates. As a result, these competitors, particularly those that have relationships with financial institutions, can reduce their fees, offering rates that are more favorable to their current and potential clients, thereby impeding our growth in the market. If as a result of competition, Linx Pay is forced to reduce its fees, we may need to intensify our cost control efforts in order to maintain and expand our market share. An intensification of competition may cause us to lose current customers and may make it difficult for us to attract new customers, which may materially adversely affect our business, financial condition and results of operations.
