LINX Linx SA

TO OUR SHAREHOLDERS

The Management of Linx S.A. (“Linx”, “Company”) submits the Financial Statements for the periods ended March 31, 2021 (“1^st quarter of 2021”, “1Q21”) to your appreciation compared to March 31, 2020 (“1^st quarter of 2020”, “1Q20”).

Linx, present in the market for 35 years, is a leader in technologies for retail, using cloud, big data, artificial intelligence, among other innovations, to create a wide portfolio of transactional and performance solutions, which include management software (POS - point of sale and ERP - enterprise resource planning), SaaS (software as a service) with emphasis on Digital (OMS and e-commerce), financial services (TEF and sub-acquiring) and cross selling (NFCe and connectivity), among many others.

The first quarter of 2021 was very hard for Brazil. New variants of the Coronavirus have been detected, the number of infections has skyrocketed across the country, health systems in several cities have collapsed and, unfortunately, the death toll has grown exponentially. As a result, stricter restrictive measures were again implemented throughout the national territory at different times according to the situation in each city or region. We also had the beginning of the vaccination period against COVID-19 for the Brazilian population. In view of this situation, e-commerce continued to be the main alternative for retailers to continue operating safely, enabling the continuity and even the expansion of their businesses.

Linx continues to develop and improve its products, systems and reinforce partnerships to support retail in this challenging period that has already completed more than a year. We integrate fast, efficient and cost-effective solutions into our portfolio for retailers in different industries and profiles. In this context, we highlight the performance of the Pharma and Food verticals; our e-commerce platform that is becoming increasingly robust, intuitive and even more integrated with business management systems and means of payment; in addition to expanding partnerships with the main marketplaces in the country for our entire customer base.

According to the Monthly Survey of Commerce (PMC) of IBGE, the volume of sales in retail trade expanded by 2.4% in March 2021 compared to the same month in 2020. However, the negative results in January and mainly in February, resulted in a decrease of 0.6% in the comparison between 1Q21 and 1Q20.

As a result, Linx Digital now represents 14.7% of total recurring revenue in 1Q21, while Linx Pay also grew and started to account for 13.1% of total recurring revenue in the same period. It is important to note that despite the restrictive measures to the retail operation, the subscription revenue of Linx Core grew 14.6% in 1Q21 when compared to 1Q20.

We still do not register material impacts on churn, due to the differentiated profile of Linx´s customer base, in addition to the low representativeness of the monthly fees charged on retailers' revenues. The accumulated volume of postponements reached BRL 79 million in the quarter, of which 99% of invoices with an extended term were up to date, an even better level than that registered in 4Q20.

We would like to highlight the excellent performance of our products aimed at e-commerce, Linx Commerce, and also for our products for Delivery, such as the Delivery App and Mercadapp, which had exponential growth in this period.

Our Opportunities Committee continues to monitor the impacts of COVID-19. In addition to the various cash protection measures that have been taken since the beginning of the pandemic, 100% of Linx employees remain in home office and, so far, there is no forecast of return to the offices.

On March 19, the CADE´s General Superintendence issued a Technical Opinion favorable to the unrestricted approval of the business combination between Linx and StoneCo. On April 7, we informed that the aforementioned Technical Opinion was appealed and is being analyzed by the CADE´s Administrative Court.

Finally, we reaffirm our commitment to the long term, ensuring the safety of our team, the service to clients and suppliers, and consequently, to the business.

The Company’s Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with Accounting Pronouncement NBC TG 21 and IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the presentation of this financial information in accordance with the rules issued by the Brazilian Securities and Exchange Commission (CVM), applicable to the preparation of Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Review Engagements (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the quarterly information referred to above is not prepared, in all material respects, in accordance with NBC TG 21 and IAS 34, applicable to the preparation of Quarterly Information (ITR), consistently with the rules issued by the Brazilian Securities and Exchange Commission.

Other matters

Statement of Value Added

This financial information was submitted to review procedures carried out jointly with the audit of Company’s quarterly information. To form a conclusion, we evaluated whether these statements are reconciled with interim financial information and accounting records, as applicable, and whether their forms and contents are in accordance with criteria defined in Technical Pronouncement NBC TG 09 – Statement of Added Value. Based on our review, we are not aware of any other event that make us believe that these statements of added value were not prepared, in all material respects, in according the criteria defined by this standard and consistently in accordance with individual and consolidated interim financial information taken as a whole.

IFRS does not require a presentation of this statement. As a consequence, under IFRS, this statement is available as supplementary information, without prejudice to the set of interim financial information.

All relevant information applicable to the interim financial information and only this, is being disclosed and these are used by management in its management.

The individual and consolidated interim financial information present comparative information in relation to the prior period.

The individual and consolidated interim financial information were prepared in accordance with measurement bases used in accounting estimates. The accounting estimates were based on objective and subjective factors, with a basis on Management's judgment for determination of the adequate amount to be recorded in the interim financial informatio. Significant items subject to these estimates and assumptions include the selection of fixed and intangible assets and its recoverability in operations, deferred taxes, evaluation of financial assets at fair value, credit risk analysis to determine the provision for estimated credit losses in doubtful accounts, and the analysis of the remaining risks to determine other provisions, including for contingencies.

The settlement and uncertainties of transactions involving judgment and assumptions of these estimates may result in significantly different amounts described in the interim financial information due to the probabilistic treatment inherent to the estimative process. Estimates and assumptions are reviewed by the Company at least annually.

Among the captions of payments of loans and financing and lease payment, in the cash flow statements, for the interim financial information of December 31, 2020, there was reclassification in order to allow comparability with the information of March 31, 2021.

On March 11, 2020, the World Health Organization (WHO) declared as a global pandemic. Also in March, Linx developed and implemented a plan covering several preventive measures required to minimize the effects of the pandemic. The main items of said plan are listed below:

After, the Company took several measures to preserve cash, which involved anticipating and reducing the costs of cloud operations, decelerating the pace of acquisitions, freezing the opening of vacancies or promotions, canceling business trips, reducing purchase orders , cost reduction with third parties and negotiation of office rentals. Negotiations were also carried out with the Banco Nacional de Desenvolvimento Econômico e Social (BNDES), with unions that represent our employees and the terms were renegotiated with suppliers. Complementary actions involved renegotiating and postponing conditions with customers (Linx had sought to negotiate invoice maturities on a case-by-case basis, according to the relationship with the customer), assessing future prospects for each business area and reducing dividend distribution related to the 2019 year.

During the second quarter of 2020, Brazil experienced its a intense period of social distancing, including measures to close commercial establishments not linked to essential services, impacting a large part of Linx's customer base.

In the third and fourth quarterly, the measures to close commercial establishments were gradually being reversed. Due to the fact that the pandemic has not yet been completely overcome and there are reflections of the period of social distance, the Company is unable to predict in the countries in which it operates the direct and indirect impacts of the coronavirus on its business, operating results and financial condition. The possible effects in the Company business will depend of the factors evolution as follow:

Thus, the Crisis Committee (currently called the Opportunities Committee) created in March continues to operate to monitor the impacts of COVID-19.

Additionally, due to the uncertainty scenario provided by the pandemic, the Company reassessed the main accounting estimates (see details in the respective explanatory notes):

• Evaluation of provision for expected loss: The Company followed the effects of the current economic scenario in the methodology for measuring estimated losses, by updating the expected loss percentages for each range of the portfolio, capturing the estimates of reflexes in default and credit recovery for the next few months;

• Impairment assessment of intangible assets with indefinite useful lives: As mentioned in note 13.1, the Company assessed the recoverability of its assets for its cash-generating units and did not identify the need for a provision for loss in the financial information for the year ended in December 31, 2020;

• Recoverability of deferred taxes: The recoverability of the balance of deferred tax assets is reviewed at least annually. In the Company's assessment, the scenario impacted by Covid19 did not affect the projections of future taxable profits, allowing the recoverability of credits in the coming years (see note 20.3).

The individual and consolidated interim financial information presented were prepared in accordance with policies, accounting practices and methods for calculating estimates adopted in the preparation of the annual financial statements for the year ended December 31, 2020.
