( Kroton ), and, on the other side, certain funds managed by Tarpon Gestora de Recursos S.A. ( Tarpon ) which are the controlling shareholders of SOMOS. The transaction has been agreed under certain conditions precedent, including approval by Conselho Administrativo de Defesa Econômica CADE. Until the closing of the transaction and the approval from CADE (Antitrust Authority), we will operate independently, according to the applicable law. In January 2018, we have launched a new school of Colégio Integrado, in the city of Goiânia. Since January 2018, we have concluded the acquisition of 3 schools in the States of Mato Grosso and Rio Grande do Norte, in which approximately 4.0 thousand students are enrolled for 2018. Financial Results Net Revenues of R$568.7 million in 1Q18 (+8.7% over 1Q17). Adjusted Gross Profit of R$364.2 million in 1Q18 (-0.3% over 1Q17). Adjusted EBITDA II of R$260.3 million in 1Q18 (+12.1% over 1Q17). 2

Adjusted Net Income of R$129.4 million in 1Q18 (+27.8% over 1Q17). Operating Cash Flow of R$110.8 million in 1Q18 (+45.7% over 1Q17). Net Debt, as of March 31 st, 2018, of R$1,253.9 million (+15.2% over March 31 st, 2017). Operational Results Total of 1.2 million students under long-term contracts, in K12 Educational Solutions as of March 31 st, 2018, including 113 thousand students in the program O Líder em Mim (OLEM) (+22.2% over March 31 st, 2017). We ended the 1Q18 with 20.4 thousand students enrolled in our Proprietary Schools, in 29 units, including the new school of Integrado, in Goiânia (GO), and the Colégio CIE, in Rondonópolis (MT), which was acquired in March 2018 (+5.4% over 1Q17). Red Balloon ended the 1Q18 with 27.5 thousand students (+11.5% over 1Q17), distributed in 132 units, among proprietary units, franchises and In School (+13.8% over 1Q17). MESSAGE FROM THE MANAGEMENT In the first quarter of 2018, we posted a growth of 8.7% in net revenues and 12.1% in Adjusted EBITDA II in comparison to 1Q17. The adjusted EBITDA II totaled R$260.3 million in 1Q18, compared to R$232.1 million in 1Q17, and the EBITDA margin has increased 1 p.p., from 44.4% in 1Q17 to 45.8% in 1Q18, due to the continuous process of integration and efficiency gains, which we have been implementing in the past three years. In Proprietary Schools, we concluded the TOTVs integration of our ph schools network in Rio de Janeiro, and the acquisition of schools in the States of Mato Grosso and Rio Grande do Norte with approximately 4.0 thousand students enrolled for 2018. In the Language business, we have followed our expansion plan and ended the first quarter with 132 units of Red Balloon, a 13.8% growth over 1Q17. In K12 Educational Solutions, we reached a total of 1.2 million students under long-term contracts, through our offerings that include learning systems, OLEM and PAR Educational Platform (an increase of 22.2% over 1Q17). ANALYSIS OF FINANCIAL PERFORMANCE Net Revenues In 1Q18, net revenues totaled R$568.7 million, an 8.7% growth over 1Q17. In K12 Educational Solutions, the growth was 14.4% (R$49.9 million increase), mainly due to Livro Fácil s marketplace and the revenues from PNLD 2018 Arts subject. In Proprietary Schools and Language, the net revenue growth was 5.5% (R$7.3 million increase) over 1Q17, mainly due to the higher number of students and higher average ticket at the Schools. In Educational Solutions for Technical and Higher Education (SETS), the reduction in net revenues in the first quarter of 2018 is mainly explained by the fact that we are no longer 3

controlling shareholders in Alfacon and, consequently, we are not consolidating its results anymore.

The reduction in the adjusted gross margin was mainly due to the K12 Educational Solutions business, as a result of a mix effect, as we had higher share of revenues coming from PNLD 2018, compared to 1Q17, besides the consolidation of Livro Fácil s marketplace results. 365,4 Adjusted Gross Profit - 1Q18 vs. 1Q17 (R$ mm) (2,4) (4,4) 2,0 3,6 364,2 1Q17 K12 SETS Schools and Language Others 1Q18 SG&A Selling, General and Administrative Expenses In 1Q18, SG&A totaled R$149.4 million (which represents 26% of net revenues), a reduction of 15.5% compared to R$176.8 million (which represented 34% of net revenues) in 1Q17. This reduction is a result of the continuous process of integration and efficiency gains, which we have been implementing in the past three years. EBITDA Adjusted EBITDA II totaled R$260.3 million in 1Q18, compared to R$232.1 million in 1Q17, which represents a 12.1% growth. The EBITDA margin increased 1 p.p. in the period, from 44.4% in 1Q17 to 45.8% in 1Q18. 4

232,1 Adjusted EBITDA II - 1Q18 vs. 1Q17 (R$ mm) 11,0 23,3 260,3 (5,1 ) (1,0 ) Financial Income In 1Q18 we recognized net financial expenses of R$46.4 million, compared to R$62.3 million reported in 1Q17. The reduction in financial expenses is related to interest on loans reflecting a lower interest rate SELIC (which is the main reference for our borrowing cost) and a lower spread after the debt refinancing we performed (see debt profile graph on the next page). Investments 1Q17 K12 SETS Schools and Language Others 1Q18 (R$ mm) 1Q18 1Q17 Financial Results (46,4) (62,3) Financial Income 17,9 20,8 Financial Expense (64,4) (83,1) Operational CAPEX in the first quarter of 2018 totaled R$69.1 million. Investments in production and content development for Learning Systems and Publishers totaled R$30.7 million in 1Q18 (vs. R$14.6 million in 1Q17). This increase was mainly due to changes in PNLD 2019 schedule, which has impacted the 1Q18 with an investment carry-on of R$8.3 million which started in 2017. Investments for acquisitions of fixed and intangible assets totaled R$38.4 million in 1Q18 (vs. R$15.4 million in 1Q17). This growth is a result of higher investments in digital platforms such as Plurall and Stoodi, besides significant non-recurring investments in updating and remodeling of some school units of Colégio ph in Rio de Janeiro and Curso Anglo in São Paulo, which totaled approximately R$18.0 million in 1Q18. Operating Cash Generation Operating cash generation in 1Q18 was R$110.8 million compared to R$76.1 million in 1Q17. The operating cash generation was positively impacted by the payments received regarding PNLD 2018, as we mentioned in the earnings release of 4Q17. 5

Capital Structure As of March 31, 2018, SOMOS Educação's consolidated net debt of R$1,253.9 million consisted of R$2,579.3 million gross debt and R$1,325.4million cash and cash equivalents. Total gross debt consists of R$2,538.8 million financial debt and R$40.5 million in debt with the sellers of the acquired companies. Of the total debt, 84% corresponds to long-term liabilities. The increase in cash and cash equivalents is a result of our recent public issuance of debentures, settled in March 2018, in the total amount of R$800.0 million. In April 2018, we have prepaid debentures issued in 2014 whose balance totaled R$603 million.
