3Q26

MESSAGE

FROM MANAGEMENT

3Q26 marked the completion of the most significant stage of Westwing's technological transformation: the full migration of its e-commerce to the Salesforce platform. Even in a transition quarter, the Company reported EBITDA (ex-IFRS 16) of -R$ 1.1 million, an improvement of R$ 1.8 million (+60.6% YoY) compared to

-R$ 2.9 million in 3Q25. Year to date, EBITDA (ex-IFRS 16) improved by R$ 7.5 million (+37.1% YoY), with the margin expanding by 6.6 p.p., confirming the consistent trajectory of improving results built over recent quarters.

The quarter's performance was supported by structural efficiency gains across the entire income statement. Gross margin expanded 1.1 p.p. YoY, to 41.3%, reflecting pricing discipline, a more profitable category mix and the greater relevance of Private Label, which reached 39.9% of GMV in the quarter (+9.3 p.p. YoY). Fulfillment expenses decreased 8.4% YoY and SG&A decreased 37.9% YoY, benefiting from non-recurring effects; excluding these effects in both periods, recurring SG&A decreased 10.1% YoY, reflecting structural efficiencies in personnel, administrative expenses and store structure. In 9M26, Contribution Margin II grew 7.7% YoY, with a margin of 18.9% (+2.2 p.p.), even with net revenue 4.5% lower, evidencing a structurally leaner and more efficient Company.

GMV totaled R$ 43.2 million in 3Q26 (-23.3% YoY) and R$ 143.0 million in 9M26 (-10.5% YoY), impacted by the migration of the e-commerce to the Salesforce platform. During the process, the Company temporarily operated both environments in parallel, and inventory integration and purchase journey adjustments affected conversion and order volume in the quarter.

The quarter's results also included non-recurring effects, mainly the recognition of extemporaneous PIS and COFINS tax credits and the reversal of the stock option plan (SOP) provision, partially offset by temporary costs of running duplicate systems during the migration. With the discontinuation of the legacy systems, the remaining costs will be fully eliminated in 4Q26 and will no longer impact results as of 1Q27, enabling the full capture of the efficiency gains of the new technology architecture.

The Company remains structured around four strategic pillars: (I) GMV growth; (II) EBITDA expansion; (III) consistent operating efficiency gains; and (IV) structural cash generation, supported by three integrated fronts:

Expansion of Private Label (Westwing Collection) and of the exclusive assortment, strengthening the brand, expanding margins and increasing control over the mix;

Raising the quality standard, with a focus on accessible design and higher added value, driving average ticket, LTV and acquisition efficiency;

Evolution of the customer experience, now supported by the new Salesforce platform, with continuous UX improvements, journey personalization and shorter delivery times, increasing conversion, retention and repeat purchases.

With the new platform in operation, the progressive discontinuation of legacy systems and a leaner cost structure, Westwing remains focused on the continuous evolution of the customer experience and on profitability discipline.

Net revenue totaled R$ 30.5 million in 3Q26 (-17.7% YoY) and R$ 100.3 million in 9M26 (-4.5% YoY), outperforming GMV in both periods. The difference is related to the higher share of own-inventory sales, whose revenue is recognized at the full sale amount, to the detriment of dropshipping, a model in which the Company recognizes only the commission revenue. This strategy increases control over the customer experience and value capture along the chain.

GMV totaled R$ 43.2 million in 3Q26 and R$ 143.0 million in 9M26, decreases of 23.3% YoY and 10.5% YoY, respectively, compared to R$ 56.3 million in 3Q25 and R$ 159.7 million in 9M25. The decrease essentially reflected the period of replacement of the legacy e-commerce by the Salesforce platform.

EBITDA (ex-IFRS 16), a metric that is not subject to the fluctuations of the accounting effect of leases, totaled

-R$ 1.1 million in 3Q26, an improvement of R$ 1.8 million (+60.6% YoY) compared to -R$ 2.9 million in 3Q25, with a margin of -3.8% (+4.1 p.p.). In 9M26, it totaled -R$ 12.7 million, an improvement of R$ 7.5 million (+37.1% YoY) compared to -R$ 20.3 million in 9M25, with the margin expanding by 6.6 p.p., to

-12.7%.

The Company continued to consistently capture efficiency gains. Fulfillment expenses totaled R$ 7.4 million in 3Q26, a decrease of 8.4% YoY, and R$ 22.9 million in 9M26 (-9.5% YoY), equivalent to 22.8% of net revenue year to date (-1.3 p.p.). SG&A totaled R$ 5.6 million in the quarter, a decrease of 37.9% YoY, driven by net non-recurring effects of R$ 8.2 million, mainly the recognition of extemporaneous PIS and COFINS tax credits and the reversal of the stock option plan (SOP) provision, partially offset by the costs of duplicate systems during the transition to the Salesforce platform.

Excluding the non-recurring effects of 3Q26 and 3Q25, the latter benefiting from extemporaneous ICMS tax credits (CAT 42), recurring SG&A decreased 10.1% YoY, to R$ 13.7 million, evidencing the efficiencies captured in personnel, administrative expenses and store structure. In 9M26, SG&A totaled R$ 32.0 million (-12.0% YoY). In total, operating expenses amounted to R$ 16.1 million in 3Q26, a decrease of 17.2% YoY.

The cash balance ended 3Q26 at R$ 40.8 million, compared to R$ 101.9 million in 3Q25, reflecting the capital reduction completed on July 1, 2026. Excluding the R$ 61.3 million in impacts related to the transaction, the cash balance would have been R$ 102.1 million, indicating cash generation of R$ 0.2 million over 12 months (excluding the effects of the capital reduction), even considering the loss of financial income resulting from the lower cash balance, estimated at R$ 2.0 million. Year to date in 2026, excluding the effects of the capital reduction, cash consumption was R$ 19.3 million, compared to R$ 25.0 million in 9M25, an improvement of R$ 5.7 million, supported by operating improvements and working capital management, with the cash conversion cycle reaching -54.4 days in 3Q26, an improvement of 64.7 days YoY.

3Q26

OPERATIONAL HIGHLIGHTS

GMV reached R$ 43.2 million in 3Q26, a decrease of 23.3% YoY compared to R$ 56.3 million in 3Q25. Year to date, GMV totaled R$ 143.0 million, a decrease of 10.5% YoY. The quarter's performance was impacted by the migration of the e-commerce to the Salesforce platform: during the process, the Company operated with efforts divided between the legacy and new environments, and specific integration adjustments, particularly in inventory synchronization, increased cancellations and reduced conversion in the quarter.

In parallel, the Company continued to advance in the diversification of its commercial fronts, expanding its network of specifiers and its presence in partner marketplaces, initiatives that extend the brand's reach and reduce dependence on paid media for demand generation.

Private Label (Westwing Collection) remained one of the Company's main drivers of differentiation and profitability, reaching a 39.9% share of GMV in 3Q26, up 9.3 p.p. from 30.6% in 3Q25. Year to date, the share also reached 39.9% in 9M26, up 14.5 p.p. from 25.4% in 9M25. The greater relevance of the private label in the mix contributed to the 1.1 p.p. gross margin expansion in the quarter and reinforces the transition to a retail model that is less dependent on promotions and more oriented toward desirability, curation and value creation.

Westwing's Branding strategy had a quarter of strong visibility, marked by the celebration of the brand's 15th anniversary and by partnerships that reinforce its positioning as a "dream brand," expanding its presence in the worlds of design, architecture, culture and lifestyle. In 3Q26, the brand earned 106 mentions in the press and on social media, which totaled approximately 18.9 million impressions (pageviews, print circulation and followers), with an estimated value of R$ 3.5 million in earned media, equivalent to the investment required to obtain similar exposure through paid media.

The main initiatives of the quarter included the 15th anniversary celebration event, with activations by partner brands, and the Spring Event, with creators and press. The period was also marked by partnerships with content creators and cultural institutions. The brand expanded its presence in strategic business, architecture and decor media outlets, such as Casa Vogue, Page 9, Estadão, Exame, InfoMoney, Claudia and Bazaar Interiors, in addition to the podcast O Varejista.

The specifier community continued to expand strongly, reaching 8,106 registered professionals in September 2026, compared to 2,017 in the same month of the previous year, representing growth of 301.9% YoY and a base approximately four times larger in 12 months. In addition, Westwing has three brand ambassadors, expanding its presence among architects, designers and opinion leaders.

The Company maintained its trajectory of improving logistics efficiency and service level. In September 2026, the average promised delivery time, which covers the entire process, from the receipt of merchandise from the supplier to final delivery to the customer, was 14.9 days, below the 15.1 days of September 2025, highlighted by the 12% reduction in Furniture and the 10% reduction in Decor and Lighting. This improvement reflects the higher concentration of sales in own inventory, the optimization of the logistics network and improved carrier management.

In the transportation stage, whose lead time corresponds to that of the carrier until delivery to the customer, the service level also improved. Westlog, Westwing's in-house logistics operation, responsible for deliveries in Greater São Paulo and in the Metropolitan Regions of Jundiaí and Campinas, operates with a transportation lead time of 1 business day and met the deadline in 100% of deliveries in 3Q26. Nationwide, the average transportation lead time fell from 6.5 business days in 3Q25 to 5.2 business days in 3Q26, and the deadline was met in 94.7% of deliveries, compared to 91.9% in 3Q25 (+2.8 p.p.).

Reflecting the continuous evolution of the customer experience, Westwing maintained the Reclame AQUI RA1000 seal and ranks in the Top 10 of Reclame AQUI's best companies in the Furniture and Decor Ecommerce category, a recognition that reinforces the Company's commitment to service quality and customer satisfaction, even in a quarter of technological transition.

With the migration completed, the new technology architecture now supports the evolution of Westwing's digital experience, with greater agility in the development and launch of features, native integration among ecommerce, CRM and physical stores, and greater capacity for journey personalization. The first performance indicators already demonstrate the gains of the new platform.

On the website, pages began to load 20% faster on mobile and 29% faster on desktop in 3Q26, compared to the period prior to the migration. With these speed gains, the mobile version of the website began to pass Google's experience assessment (Core Web Vitals), which also favors visibility in search results.

In the app, the speed gains were even more significant:

Login 8x faster: the time to sign in to the account went from 20 seconds to 2.5 seconds;

Navigation 10x faster: moving from one screen to another went from 15 seconds to 1.5 seconds;

Checkout 3.5x faster: the purchase process went from 10.62 seconds to 3 seconds.

The Company continues the process of discontinuing its legacy systems, and the remaining costs of duplicate systems will be fully eliminated in 4Q26, no longer impacting results as of 1Q27.

3Q26

FINANCIAL HIGHLIGHTS

Net revenue totaled R$ 30.5 million in 3Q26, a decrease of 17.7% YoY, and R$ 100.3 million in 9M26 (-4.5% YoY), outperforming GMV in both periods due to the higher share of own-inventory sales. The return rate remained stable at 6.8% of gross revenue in the quarter, in line with 3Q25.

The Company reported gross profit of R$ 12.6 million in 3Q26 (-15.4% YoY), with gross margin expanding to 41.3% (+1.1 p.p. vs. 3Q25). In 9M26, gross profit totaled R$ 41.8 million (-2.4% YoY), with a margin of 41.7% (+0.9 p.p.). Excluding dropshipping commission revenue, gross margin reached 39.2% in the quarter (+3.9 p.p.) and 38.2% year to date (+2.6 p.p.). This improvement reflects pricing gains, the prioritization and positioning of Private Label, better commercial negotiations and a more profitable category mix, particularly Kitchen and Tableware.

Operating expenses totaled R$ 16.1 million in 3Q26, a decrease of 17.2% compared to R$ 19.5 million in 3Q25. Both quarters were affected by non-recurring effects, all recorded in SG&A. In 3Q26, these effects reduced expenses by R$ 8.2 million, due to the recognition of extemporaneous PIS and COFINS tax credits (R$ 5.1 million) and the reversal of the stock option plan (SOP) provision, of R$ 4.2 million, partially offset by R$ 1.1 million in temporary costs of duplicate systems during the migration to the Salesforce platform. In 3Q25, non-recurring effects reduced expenses by R$ 6.3 million, mainly extemporaneous ICMS tax credits (CAT 42).

Excluding these effects in both periods, operating expenses totaled R$ 24.3 million in 3Q26, a decrease of 5.8% compared to R$ 25.8 million in 3Q25, evidencing continued efficiency gains even in a quarter of technological transition. In 9M26, operating expenses totaled R$ 66.1 million, below the R$ 66.6 million of 9M25 (-0.7% YoY), despite the 46.6% increase in depreciation and amortization, mainly due to the accelerated amortization of legacy systems replaced by the Salesforce platform.

Fulfillment: fulfillment expenses totaled R$ 7.4 million in 3Q26, a decrease of 8.4% YoY (savings of R$ 0.7 million), reflecting lower volume and operating efficiencies in freight, packaging and payment methods, the latter down 40.0% YoY, favored by the payment mix. As a percentage of net revenue, the indicator reached 24.2% (21.8% in 3Q25), due to the lower dilution of fixed logistics costs during the transition period. In 9M26, expenses totaled R$ 22.9 million (-9.5% YoY, savings of R$ 2.4 million), equivalent to 22.8% of net revenue (-1.3 p.p.), with efficiencies in personnel and in the distribution center structure.

SG&A: SG&A totaled R$ 5.6 million in 3Q26, a decrease of 37.9% YoY compared to R$ 9.0 million in 3Q25, equivalent to 18.3% of net revenue (-6.0 p.p.), benefiting from the non-recurring effects described above. Excluding these effects in 3Q26 and 3Q25, recurring SG&A decreased 10.1% YoY, to R$ 13.7 million, compared to R$ 15.3 million in 3Q25, reinforcing the structural efficiency gains in personnel, administrative expenses and store structure, as shown in the reconciliation below. In 9M26, SG&A totaled R$ 32.0 million (-12.0% YoY), equivalent to 31.9% of net revenue (-2.7 p.p.).

Recurring SG&A Reconciliation

Marketing: marketing expenses totaled R$ 3.4 million in 3Q26, practically stable compared to R$ 3.4 million in 3Q25 (-0.3% YoY), maintaining investments focused on brand awareness, in line with the strategy of positioning Westwing as a "dream brand." During the platform migration, the Company

fine-tuned the allocation of investments, prioritizing higher-return channels and brand-building initiatives. In 9M26, marketing expenses totaled R$ 13.3 million, compared to R$ 9.2 million in 9M25 (+44.2% YoY), reflecting the intensification of brand-building investments throughout 1H26.

Contribution Margin II totaled R$ 5.2 million in 3Q26, with a margin of 17.1% of net revenue (18.4% in 3Q25), supported by the 1.1 p.p. gross margin expansion, which partially offset the lower dilution of fulfillment costs during the transition period. In 9M26, CM II grew 7.7% YoY, to R$ 18.9 million, with a margin of 18.9% (+2.2 p.p. YoY), a result that evidences the solidity of the Company's operating profitability despite the decrease in revenue.

EBITDA (ex-IFRS 16) totaled -R$ 1.1 million in 3Q26, an improvement of R$ 1.8 million (+60.6% YoY) compared to -R$ 2.9 million in 3Q25, with the margin expanding by 4.1 p.p., to -3.8%. In 9M26, EBITDA (ex-IFRS 16) totaled -R$ 12.7 million, an improvement of R$ 7.5 million (+37.1% YoY), with the margin going from -19.3% to -12.7% (+6.6 p.p.).

The quarter's improvement was driven by the reduction in SG&A expenses (+R$ 3.4 million), of which R$ 1.5 million resulted from recurring efficiencies in personnel, administrative expenses and store structure, while R$ 1.9 million reflected the greater effect of non-recurring items compared to 3Q25. The reduction in fulfillment expenses (+R$ 0.7 million) also contributed to the improvement. These effects more than offset the decrease in gross profit, while marketing expenses remained practically stable year over year.

EBITDA Breakdown

Net income (loss) for 3Q26 was -R$ 2.7 million, compared to R$ 1.9 million in 3Q25. On the operating side, EBITDA (ex-IFRS 16) improved by R$ 1.8 million YoY, an improvement that was more than offset mainly by two factors: (i) the R$ 4.4 million decrease in the financial result, due to the lower cash balance following the return of capital to shareholders; and (ii) the change in income tax and social contribution (IR/CSLL), which went from a benefit of R$ 0.8 million in 3Q25, resulting from the recognition of deferred income tax, to an expense of R$ 0.5 million in 3Q26. The IR/CSLL expense for the quarter is associated with the reversals of provisions that occurred in the period, essentially that of the stock option plan (SOP), of R$ 4.2 million, which generated a deferred income tax charge of R$ 1.4 million. Excluding this effect, IR/CSLL would have been positive by R$ 0.9 million in 3Q26 and by R$ 2.0 million in 9M26.

In 9M26, net income (loss) totaled -R$ 14.3 million, compared to -R$ 9.5 million in 9M25. The change mainly reflects the increase in depreciation and amortization expenses, which went from R$ 10.7 million to R$ 15.7 million, mostly due to the accelerated amortization of legacy systems replaced by the Salesforce platform, and the R$ 4.5 million decrease in the financial result, resulting from the lower cash balance following the return of capital to shareholders. With the completion of the replacement of legacy systems, the Company expects to fully capture the efficiency gains arising from the new technology architecture.

The Company ended 3Q26 with cash and cash equivalents of R$ 40.8 million, compared to R$ 101.9 million in 3Q25. The change essentially reflects the capital reduction completed on July 1, 2026, whose impacts on cash totaled R$ 61.3 million: (i) R$ 60.0 million from the return of capital to shareholders; and (ii) R$ 1.3 million of income tax levied on the redemption of financial investments.

Excluding these effects, the cash balance would have been R$ 102.1 million, above the R$ 101.9 million of 3Q25, representing cash generation of R$ 0.2 million over 12 months (excluding the effects of the capital reduction). This result was achieved even with the loss of financial income estimated at R$ 2.0 million, resulting from the lower cash balance following the return of capital, and reflects the Company's operating improvement combined with discipline in working capital management.

Year to date in 2026, excluding the effects of the capital reduction, cash consumption was R$ 19.3 million, compared to R$ 25.0 million in 9M25, a reduction of R$ 5.7 million (-22.8% YoY). This improvement reflects the operating progress in the period, particularly the gross margin expansion and the reduction in fulfillment and SG&A expenses, in addition to disciplined working capital management, evidenced by the reduction in inventories and accounts receivable, with the cash conversion cycle reaching -54.4 days in 3Q26.

Working capital management remains one of the main drivers of the Company's structural cash evolution. The cash conversion cycle reached -54.4 days in 3Q26, an improvement of 64.7 days compared to 10.3 days in 3Q25, and reflects a consistent downward trajectory: from 3.1 days in 1Q25, the indicator turned negative as of 4Q25 (-25.9 days) and continued to decline throughout 2026, going from -23.4 days in 1Q26 to -47.8 days in 2Q26 and -54.4 days in 3Q26. In practice, the Company receives payment from its customers and turns its inventory before paying its suppliers, financing its operations without additional cash consumption. On a year-over-year basis, the improvement was supported by all three components of the cycle:

This reflects the maturation of the sales and operations planning (S&OP) initiatives, the active management of slow-moving items and greater efficiency in the allocation of invested capital. Compared to 2Q26, the indicator reflected the one-off replenishment of inventories and the lower cost of goods sold base in the platform transition quarter;

Days Sales Outstanding (DSO): a reduction of 16.2 days, from 53.2 days in 3Q25 to 37.0 days in 3Q26, with accounts receivable going from R$ 33.6 million to R$ 19.9 million (-40.7%), reflecting the evolution of the payment methods mix;

Days Payable Outstanding (DPO): an increase of 15.5 days, from 148.1 days in 3Q25 to 163.6 days in 3Q26, evidencing the improvement in commercial terms with suppliers.

GLOSSARY

GMV

GMV represents the total amount paid, in Brazilian reais, by buyers for the purchase of products or services successfully provided and completed through the Company's sales formats.
