MESSAGE FROM MANAGEMENT

As we conclude the third quarter of the current sales cycle, Vasta´s net revenue reached R$1,488 million, a 14% increase compared to the same period of the 2024 sales cycle, mostly due to the conversion of ACV bookings into revenue. Accumulated subscription revenue in the 2025 sales cycle to date totaled R$1,340 million, a 16% increase year-over-year, reflecting our ability to sustain revenue growth. Our complementary solutions also posted strong performance, growing 24% in the 2025 sales cycle compared to the same period of 2024, supported by accelerated expansion in both student base and market penetration. The number of partners-school using our complementary solutions increased to a total of 2,149 schools.

Start-Anglo bilingual school operations continue to gain momentum, having generated R$4 million in subscription revenue during the 2025 sales cycle to date. This performance reinforces Start-Anglo’s strategic relevance and its potential to become a significant growth driver. In a short time, Start-Anglo has moved from concept to reality, with seven operating units in 2025. As of this date, Start-Anglo has secured more than 50 contracts, including two flagship schools, a notable increase from 30 contracts signed in the same period of the 2024 sales cycle. We are actively working to convert our robust pipeline — currently over 250 prospects — into new agreements for Start-Anglo.

In the B2G segment, we recorded R$9 million in net revenue this quarter coming from new municipality customers, for a total of R$50 million net revenue in the 2025 sales cycle to date. In the 2024 sales cycle, we had booked R$69 million in net revenue, as the totality of revenues from our contract with the State of Pará (1st and 2nd semesters) was recognized in 1Q24. In the 2025 sales cycle to date, the 1^st semester under our contract with Pará contract was booked in 4Q2024, and the 2^nd semester is expected to be performed in the second half of 2025. We remain confident in our strategy to positively impact public education by serving this segment and its students with our extensive portfolio of core content solutions, digital platforms, and additional offerings, including custom learning solutions developed over decades in the private sector.

The continued growth of the company's profitability was another highlight of the 2025 sales cycle to date as the Adjusted EBITDA grew by 8% to R$462 million compared to R$428 million in the previous year, and Adjusted EBITDA Margin decreased from 32.7% in the same period of the 2024 sales cycle to 31.1% in the 2025 sales cycle to date. In proportion to net revenue, gross margin decreased 2.4 p.p. in the sales cycle to date, mainly due to a different mix of products, lower B2G revenues and higher marketing expenses related to business expansion.

Cash flow generation continues to be a key strength and one of the main highlights of the 2025 sales cycle to date. Free cashflow (FCF) totaled R$224 million, a R$134 million increase from R$90 million in the same period of the 2024 sales cycle. The last twelve-month (LTM) FCF/Adjusted EBITDA conversion rate improved from 31.9% to 57.7% reflecting Vasta’s growth and the implementation of sustained efficiency measures. Additionally, the first semester of 2025  benefited from early collections relative to the 2025 sales cycle, which are expected to normalize throughout the next quarters of the year.

It is worth saying that these measures include certain improvements in our collection processes, including automation, reminders and past-due notifications, customer segmentation, and faster renegotiation of overdue receivables. On the payments side, we implemented several initiatives to enhance discipline in payments, such as rigorous financial planning, centralized payments scheduling, and negotiating longer payment terms with suppliers.

Moreover, we continue to make progress in deleveraging the company. The net debt/LTM adjusted EBITDA as of the end of 2Q25 was 1.90x, down 0.38x from 2Q24 and 0.16x from 1Q25, reinforcing our commitment to long-term value creation to our stakeholders.

Note: n.m.: not meaningful

In the 2025 sales cycle to date, Adjusted EBITDA reached R$462 million, representing an increase of 8.1% in comparison to the same period of the 2024 sales cycle, with a margin of 31.1%, compared to 32.7% in the same period of the 2024 sales cycle. This increase in Adjusted EBITDA was mainly driven by gains in operating efficiency and improvement in PDA (provision for doubtful accounts), which offset lower net revenue in the B2G segment. In 2Q25, Adjusted EBITDA totaled R$ 42 million, a 62.4% increase compared to R$ 26 million in 2Q24, mainly impacted by growth in core content and B2G.

In the 4^th quarter of 2024, which is the first quarter of 2025 sales cycle, the Company proceeded with the partial reversal of the tax contingencies, based on the opinion of its legal advisors, related to the discussions of goodwill and other subjects derived from the acquisition of the Anglo Group in 2010 and subsequent restructuring, in the total amount of R$ 532,717, comprising (i) R$ 92,558 reversals of the principal portion, which impacted positively our general and administrative expenses (ii) R$ 233,198 reversals of the income tax and social contribution, (iii) R$ 206.961 reversal of interest and fines, in the Finance result.

(1) Sum of general and administrative expenses, other operating income and profit (loss) of equity-accounted investees, less: depreciation and amortization, layoffs related to internal restructuring, share-based compensation plan and M&A one-off adjusting expenses.

Gross margin decreased 2.4 p.p. in the sales cycle to date mainly due to a different sales mix and lower net revenue in the B2G segment. Complementary solutions have grown at a faster pace despite royalties being owed to the owners of certain products. Adjusted cash G&A expenses declined by 0.5 p.p. driven by workforce optimization and budgetary discipline. Commercial expenses increased by 0.6 p.p. reflecting higher expenses related to business expansion and marketing investments. Provision for doubtful accounts (PDA), decreased by 0.9 p.p. in the 2025 sales cycle, mainly due to an additional provision booked in the 2024 sales cycle for expected credit losses related to customers in mainstream brands.

ESG

Sustainability Report

In July 2025, we disclosed Vasta´s fourth sustainability report regarding the year of 2024 and it was prepared in accordance with international standards and the implementation of our corporate strategy, challenges, and achievements, while also reaffirming our commitment to transparency and sustainability. These include the publication of Greenhouse Gas Inventory (carried out since 2020), the maintenance of the FSC certifications (since 2008), the SOMOS Institute, devoted to building a more equitable society by creating opportunities for all who believe in the power of education, and 43% of our Board members belonging to underrepresented groups (women and LGBTQIAPN+).

The report complies with the Global Reporting Initiative (GRI) 2021 version and considers other standards recognized in Brazil and abroad, such as the Sustainability Accounting Standards Board (SASB) guidelines for the education sector, the guidelines of the IBC Stakeholder Capitalism Metrics from the World Economic Forum, and the principles of the International Integrated Reporting Council (IIRC).

We continue to maintain the Somos Futuro Program via Instituto SOMOS. The initiative enables public school students to attend high school at one of Vasta's partner schools. In this quarter, 227 young people were studying through the program, receiving didactic and paradidactic material, online school tutoring, mentoring, and access to the entire support network of the program, which includes psychological monitoring, in addition to the scholarship offered by the school..

During the quarter, we conducted the April Green Workshop, which engaged employees in topics related to contractor hiring procedures and third-party management, as well as safety protocols for high-risk activities and workplace safety best practices. Other significant initiatives during this period included the production of the "Lifestyle" podcast and the World Health Day campaign titled "Preventing Disease and Taking Care of You”. Additionally, the increase in the number of trained employees is attributed to the mandatory training renewal schedule, which is conducted according to the recycling periods established by regulatory standards.

During the quarter, we recorded a significant increase in the number of reports due to intensified communication and awareness around the Cogna Confidential Channel (CCC), which was integrated into the Ombudsman Portal. This strategy facilitated access to the Channel, allowing requesters to be redirected to the CCC even when initial contact occurs through the ombudsman's office.

The Privacy Portal underwent a migration process to the Compliance section of the Cogna website. As a result, there was a slight reduction in the volume of cases received through the Portal, which are now primarily related to data subjects' rights as provided under Brazil's General Data Protection Law (LGPD). Due to the enrollment period, which occurs at the beginning of the year, there was a decrease in complaints received compared to last quarter.

NON-GAAP FINANCIAL MEASURES

This press release presents our EBITDA, Adjusted EBITDA and Adjusted net (loss) profit and Free cash flow (FCF), which is information provided for the convenience of investors. EBITDA and Adjusted EBITDA are among the key performance indicators used by us to measure financial operating performance. Our management believes that these Non-GAAP financial measures provide useful information to investors and shareholders. We also use these measures internally to establish budgets and operational goals to manage and monitor our business, evaluate our underlying historical performance and business strategies and to report our results to the board of directors.

We calculate EBITDA as net (loss) profit for the period/year plus income taxes and social contribution plus/minus net finance result plus depreciation and amortization. The EBITDA measure provides useful information to assess our operational performance.

We calculate Adjusted EBITDA as EBITDA plus/minus: (a) income tax and social contribution; (b) net finance result; (c) depreciation and amortization; (d) share-based compensation expenses, mainly due to the grant of additional shares to Somos’ employees in connection with the change of control of Somos to Cogna (for further information refer to note 23 to the audited consolidated financial statements); (e) provision for risks of tax, civil and labor losses regarding penalties, related to income tax positions taken by the Predecessor Somos – Anglo and Vasta in connection with a corporate reorganization carried out by the Predecessor Somos – Anglo; (f) Bonus IPO, which refers to bonus paid to certain executives and employees based on restricted share units; and (g) expenses with contractual termination of employees due to organizational restructuring. We understand that such adjustments are relevant and should be considered when calculating our Adjusted EBITDA, which is a practical measure to assess our operational performance that allows us to compare it with other companies that operates in the same segment.

We calculate Adjusted net (loss) profit as the (loss) profit for the period/year as presented in Statement of Profit or Loss and Other Comprehensive Income adjusted by the same Adjusted EBITDA items, however, added by (a) Amortization of intangible assets from Business Combination and (b) Tax shield of 34% generated by the aforementioned adjustments.

We calculate Free cash flow (FCF) as the cash from operating activities as presented in the Statement of Cash Flows less (a) income tax and social contribution paid; (b) tax, civil and labor proceedings paid; (c) interest lease liabilities paid; (d) acquisition of property, plant and equipment; (e) additions to intangible assets; and (f) lease liabilities paid.

We understand that, although Adjusted net (loss) profit, EBITDA, Adjusted EBITDA, and Free cash flow (FCF) are used by investors and securities analysts in their evaluation of companies, these measures have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results of operations as reported under IFRS. Additionally, our calculations of Adjusted net (loss) profit, Adjusted EBITDA, and Free cash flow (FCF) may be different from the calculation used by other companies, including our competitors in the education services industry, and therefore, our measures may not be comparable to those of other companies.

REVENUE RECOGNITION AND SEASONALITY

Our main deliveries of printed and digital materials to our customers occur in the last quarter of each year (typically in November and December), and in the first quarter of each subsequent year (typically in February and March), and revenue is recognized when the customers obtain control over the materials. In addition, the printed and digital materials we provide in the fourth quarter are used by our customers in the following school year and, therefore, our fourth quarter results reflect the growth in the number of our students from one school year to the next, leading to higher revenue in general in our fourth quarter compared with the preceding quarters in each year. Consequently, in aggregate, the seasonality of our revenues generally produces higher revenues in the first and fourth quarters of our fiscal year. Thus, the numbers for the second quarter and third quarter are usually less relevant. In addition, we generally bill our customers during the first half of each school year (which starts in January), which generally results in a higher cash position in the first half of each year compared to the second half.

A significant part of our expenses is also seasonal. Due to the nature of our business cycle, we need significant working capital, typically in September or October of each year, to cover costs related to production and inventory accumulation, selling and marketing expenses, and delivery of our teaching materials at the end of each year in preparation for the beginning of each school year. As a result, these operating expenses are generally incurred between September and December of each year.

Purchases through our Livro Fácil e-commerce platform are also very intense during the back-to-school period, between November, when school enrollment takes place and families plan to anticipate the purchase of products and services, and February of the following year, when classes are about to start. Thus, e-commerce revenue is mainly concentrated in the first and fourth quarters of the year.

KEY BUSINESS METRICS

Annual Contract Value, or ACV, is a non-accounting managerial metric and represents our partner schools’ commitment to pay for our solutions offerings. We believe it is a meaningful indicator of demand for our solutions. We consider ACV is a helpful metric because it is designed to show amounts that we expect to be recognized as revenue from subscription services for the 12-month period between October 1 of one fiscal year through September 30 of the following fiscal year. We define ACV as the revenue we would expect to recognize from a partner school in each school year, based on the number of students who have contracted our services, or “enrolled students,” that will access our content at such partner school in such school year. We calculate ACV by multiplying the number of enrolled students at each school with the average ticket per student per year; the related number of enrolled students and average ticket per student per year are each calculated in accordance with the terms of each contract with the related school. Although our contracts with our schools are typically for 4-year terms, we record one year of revenue under such contracts as ACV. ACV is calculated based on the sum of actual contracts signed during the sales period and assumes the historical rates of returned goods from customers for the preceding 24-month period. Since the actual rates of returned goods from sales during the period may be different from the historical average rates and the actual volume of merchandise ordered by our customers may be different from the contracted amount, the actual revenue recognized during each period of a sales cycle may be different from the ACV for the respective sales cycle. Our reported ACV is subject to risks associated with, among other things, economic conditions and the markets in which we operate, including risks that our contracts may be canceled or adjusted.
