Kaspi.kz 1Q 2026 Financial Results

Almaty, Kazakhstan, 11 May 2026 – Joint Stock Company Kaspi.kz (“Kaspi.kz”, “we”) (Nasdaq:KSPI) today published its unaudited consolidated IFRS financial results for the quarter ended 31 March 2026 (“1Q 2026”).

Letter from Mikheil Lomtadze, Co-Founder and CEO of Kaspi.kz:

We’ve started the year with strong e-Commerce growth, higher purchase frequency and improving monetization. e-Commerce GMV grew 41% year-over-year on a constant-currency and pro-forma basis and orders grew 43% on pro-forma basis. Consumers are buying more frequently — purchases per consumer increased 44% to 15 purchases per quarter.

At the same time, Kaspi.kz remained highly profitable, with adjusted EBITDA growing 9%. Our Board recommended a dividend of KZT 850 per ADS, representing a 64% payout ratio, subject to shareholder approval. This reflects confidence in our cash generation and our growth outlook.

The most important message is simple: Kaspi.kz is becoming a larger, more diversified platform, with far greater growth potential than ever before. Building on our position as Kazakhstan’s leading Super App, we are now creating an international business.

e-Commerce is now one of our most important growth engines. It deepens customer engagement, expands our addressable market and creates monetization opportunities across advertising, delivery, payments and fintech. Advertising and delivery revenue grew 73% during the quarter, showing that e-Commerce is not only scaling, but becoming more monetizable over time.

Türkiye is a market of 85 million people and an important part of our next growth phase. It now represents 50% of our e-Commerce GMV. We are bringing Kaspi’s product culture and e-Commerce, payments and fintech expertise to Türkiye — with a long-term and disciplined approach.

Kaspi.kz is a profitable, dividend-paying platform with multiple growth engines, and our goal is clear: to build an even stronger company while staying true to our mission of improving people’s lives by developing innovative mobile products and services.

My personal investment alongside Tencent and other long-term investors reflects my strong confidence in Kaspi.kz’s long-term opportunity. As co-founder and CEO, I remain fully aligned with all shareholders.

Thank you for your continued trust and support.

1Q 2026 Highlights

Going forward, our first and third quarter releases will focus primarily on trading and financial trends during the period, while our interim and full-year results will include more detailed product and strategic updates.

Kaspi.kz 1Q 2026 Financials

Total revenue increased 31% year-over-year to KZT1.1 trillion ($2.3 billion). Revenue growth was mainly driven by improving order frequency and fast growth from VAS in our e-Commerce business, strong Fintech loan portfolio growth, alongside robust and predictable growth from our Payments Platform.

Adjusted EBITDA increased 9% year-over-year to KZT368 billion ($768 million). Consolidated net income was broadly stable at KZT252 billion ($526 million), down 1% year-over-year. Net income margin was impacted by higher deposit funding costs following interest rate increases in Kazakhstan last year and the full-quarter consolidation of Hepsiburada.

Growth in COGS year-over-year is mainly due to Hepsiburada being consolidated for the entire quarter in 2026, compared with approximately two months in 1Q 2025. As previously communicated, we are choosing to operate Hepsiburada at around EBITDA breakeven as we prioritize investment in its future growth.

Marketplace Platform

Within Marketplace, pro-forma e-Commerce GMV increased 41% year-over-year to KZT1.3 trillion ($2.6 billion) during the first quarter of 2026. In both Kazakhstan and Türkiye, we’re prioritising improving consumer engagement; this is illustrated by purchases per consumer increasing to 15 from 10.4 in the first quarter of 2025.

We’re also seeing good results growing revenue from value-added services, namely advertising and delivery. During 1Q 2026, VAS revenue increased 73% year-over-year. As a result, e-Commerce 3P take rate increased 90 bps year-over-year to 15.8%, and e-Commerce revenue grew significantly faster than GMV. During 1Q 2026, e-Commerce revenue increased 58% year-over-year to KZT394 billion ($824 million).

Marketplace constant-currency and pro-forma GMV increased 19% year-over-year, driven by strong e-Commerce growth in Kazakhstan and Türkiye. Take rate improved 100 bps year-over-year to 12.1%, resulting in Marketplace revenue growing 49% year-over-year to KZT520 billion ($1.1 billion). Adjusted EBITDA grew 12% year-over-year to KZT118 billion ($247 million). Adjusted EBITDA growth was impacted by Hepsiburada, which generates around a third of its GMV from 1P retail, being consolidated for the entire first quarter in 2026, compared with approximately 2 months in 1Q 2025.

Payments Platform

During 1Q 2026, TPV increased 14% year-over-year to KZT11.4 trillion ($23.7 billion).

Payments revenue increased 7% year-over-year to KZT158 billion ($331 million). Revenue growth trailing TPV growth reflects take-rate decline to 1.03% from 1.09% in 1Q 2025. This is due to shifting product mix and is consistent with long-run trends. Interest revenue accounted for 26% of total revenue and increased 26% year-over-year.

Adjusted EBITDA was flat year-over-year at KZT90 billion ($187 million). Adjusted EBITDA excludes interest revenue. However, overall profitability remains high, and Payments’ capital-light model makes it highly cash generative, while Payments’ products drive high levels of day-to-day customer engagement.

Fintech Platform

During 1Q 2026, TFV origination declined 2% year-over-year, to KZT2.6 trillion ($5.4 billion). Over the same period, our average net loan portfolio increased by 23% year-over-year, to KZT7.2 trillion ($15.1 billion).

We are deliberately shifting our lending mix toward longer-duration, higher-revenue products. Average loan portfolio duration was 9.3 months in 1Q 2026, compared with 7.9 months in 1Q 2025. Portfolio yield was stable year-over-year at around 6%. As a result, Fintech revenue significantly outperformed TFV dynamics and increased 25% year-over-year to KZT430 billion ($897 million).

Interest rate increases in Kazakhstan last year resulted in our cost of funding for deposits increasing 220 bps year-over-year to 14.3%. Cost of Risk was 0.7% in 1Q 2026 compared with 0.6% in the same period in 2025. Our underlying credit trends remain strong and consistent.

Our NPL ratio of 6.6% in 1Q 2026 was higher than the 6.1% seen in full-year 2025. Lower coverage reflects the growing share of lower risk car and merchant loans in our portfolio, as well as ongoing improvements in our collection processes.

Higher deposit costs and a slightly higher Cost of Risk negatively impacted Fintech adjusted EBITDA growth which increased 12% year-over-year to KZT160 billion ($334 million).

Use of key financial & operating metrics

Certain parts of this press release contain our key financial and operating metrics, which we do not consider to be non-IFRS financial measures. We use these metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions.

Non-IFRS financial measures

To supplement our results presented in accordance with IFRS, we present Adjusted EBITDA for both the Company and Hepsiburada on a standalone basis. The Company provides a reconciliation of Adjusted EBITDA, a non-IFRS financial measure for historical periods. However, the Company does not provide guidance on net income and is unable to provide a reconciliation for its Adjusted EBITDA guidance range to net income without unreasonable efforts due to high variability and complexity with respect to estimating certain forward-looking amounts, the probable significance of which cannot be determined. The adjustments from net income for these forward-looking amounts include, for Adjusted EBITDA of the Company, earnings before interest revenue from other operations, interest expenses and fees from other operations, share-based compensation expense, other gains (losses), income tax expense, and depreciation and amortization expenses, and for

Adjusted EBITDA of Hepsiburada on a standalone basis, taxation on income, financial income, financial expenses, depreciation and amortization, and monetary gain/(loss).

Exchange rate calculations

The Kazakhstani tenge (KZT) to US dollar ($) exchange rate used by us for the presentation of certain financial, operating and other data denominated in tenge and included in this presentation is KZT478.77 per $1 as of 31 March 2026.
