Letter from the CEO Dear fellow shareholders, The malfunctioning markets that built modern finance are ending. For decades, banks and tech companies thrived on customer lock-in, hidden fees, and information asymmetry. AI is now dismantling those barriers — and Klarna is leading the way. Q3 proved it. This was our strongest quarter ever. Revenue hit $903 million, up 51% in the U.S. and 28% globally in Q3, while GMV reached $32.7 billion, with 3.4 million transactions every day. The Klarna Card has exploded since its July launch — over four million signups, already 15% of all global transactions1. Consumers are voting with their wallets for transparency and control. Our Fair Financing offering grew 244% in the U.S., taking massive share in fixed-term lending — Fair Financing has a transaction margin over twice the group average2. While accounting rules recognize provisions upfront, the long-term economics are powerful. We expect over $100 million in transaction margin uplift in Q4 as compounding revenue kicks in. On a realized loss basis, transaction margin dollars already grew 25% in Q33. Even as we grow, our discipline strengthens. Realized losses fell 1 basis point to 0.44% of GMV year- on year — proof our underwriting works at scale. More consumers are paying early, not late. That’s what responsible finance looks like. And we’re just getting started. The Klarna Card and our new membership program — already over one million members — are redefining everyday banking for the post-AI era: debit-first, transparent, empowering. We’re not asking customers to adapt to us; we’re building products that adapt to them. To our shareholders, old and new: thank you for backing this mission. We’ve entered a new chapter — not just as a listed company on the New York Stock Exchange, but as the first truly global digital bank built for the world after AI. Sebastian Siemiatkowski CEO and co-founder, Klarna 3 1 Card transactions as a percentage of total transactions in October 2025. 2The expected lifetime transaction margin for Q1 2025 Fair Financing GMV cohort. 3 Transaction margin dollars (TMD) is a non-IFRS measure. Please refer to “Non-IFRS Measures and Reconciliations” for reconciliation to the most directly comparable IFRS measure. TMD based on realised losses is calculated as revenue minus processing and servicing costs, realised losses and funding costs before the Klarna Checkout (KCO) disposal. It excludes upfront provisions.

Letter from the CFO Dear fellow shareholders, In the third quarter of 2025, Klarna delivered accelerated growth and record GMV and Revenues. Growth was broad-based Like-for-like GMV rose 23% (up from 19% in Q2), including the U.S. up +43% LfL, Southern Europe +73% LfL and Sweden +18% LfL. Revenue reached $903 million, up 26% like-for-like compared to Q3’24, our highest quarter ever, with take rate expanding to 2.76% supported by the U.S. and Fair Financing mix. Expanding global reach Our merchant network added 235,000 new partners year-over-year, now totaling 850,000. Stripe continues to be a key contributor, while partnerships with Worldpay, Nexi, and JPMorgan Payments will extend distribution further. We also expanded with leading global brands — including OnePay Later Powered by Klarna at Walmart, eBay (now in eight markets), and Qatar Airways — strengthening Klarna’s position as the preferred partner for digital commerce. The Klarna Card continued its surge, with GMV up 92% year-over-year in the quarter and four million signups since launch in July. The card’s rapid adoption demonstrates consumers’ appetite for debit- first flexibility and Klarna’s global product scalability. Scaling Fair financing Fair Financing continued to scale rapidly, with U.S. GMV up 244% year-over-year and globally by 139%. Fair financing is now available at 151 thousand merchants, 18% of our merchants, up from 10% two years ago. The accounting treatment of upfront provisions for Fair Financing means the underlying economics are not fully captured in the quarter of origination, as credit loss provisions are recognized immediately while revenues accrue over the life of the loan. For example, this quarter we delivered 139% growth in Fair Financing GMV but only 48% growth in interest income. The rest will flow through in subsequent quarters as customers make repayments over the life of the loan. Margins for Fair Financing over the life of the loan are over twice the group average, and transaction margin dollars on a realized loss basis grew 25% in Q3 excluding KCO. We expect >$100 million uplift in Transaction margin dollars in Q4 compared to Q3 as revenue compounds. 4 Months Illustrative example (Fair Financing) Cumulative revenue Provision for credit losses 1 2 3 4 5 6

Credit quality remains strong Realized losses fell to 1 basis point YoY to 0.44% of GMV. Fair Financing delinquencies improved 5% YoY, the increase in provisions for credit losses (0.72% of GMV) simply reflecting the accelerated growth of the Fair Financing portfolio. Note: “Upfront provisions” primarily reflect potential losses at origination as well as changes in credit risk of on-book loans. Through the new forward flow agreements, Klarna has secured additional capacity for $6.5 billion of Fair Financing growth, with $1.2 billion in receivables sales expected in Q4, improving liquidity and accelerating revenue recognition. 5 Provision for credit losses (% of GMV) 0.44% 0.53% 0.53% 0.55% 0.72% 0.45% 0.39% 0.48% 0.45% 0.44% (0.01)% 0.14% 0.05% 0.10% 0.28% Realized losses Upfront provisions Q3’24 Q4'24 Q1'25 Q2'25 Q3’25 Provision for credit losses as a % of GMV increased, driven by the upfront provisions we’re required to book when growing the Fair Financing portfolio Quarter of origination Fair Financing 60+ days past due delinquency rates U.S. Group Q1'22 Q1'23 Q1'24 Q1’25 0.0% 2.0% 4.0% 6.0% Months since origination U.S. Fair Financing charge-offs 2022 Q1 23 Q2 23 Q3 23 Q4 23 Q1 24 Q2 24 Q3 24 Q4’24 6 8 10 12 14 16 18 20 22 24 0.0% 2.0% 4.0% 6.0% Realized losses as a percentage of GMV were one basis point lower compared to last year

Operational efficiency continues to expand Revenue has grown 108% since Q3’22, while operating expenses have increased only 2%, driven by Klarna’s AI-enabled productivity and cost discipline4. In the third quarter, our technology and engineering spend increased driven by select investment and lower capitalization. Investments in sales and marketing were in-line with recent quarters. We continue to sustain strong momentum without compromising cost discipline, as operating expenses continue to drop as a percentage of revenue. Klarna delivered a better than planned adjusted operating loss of $14 million (net loss of $95 million), despite the impact of the upfront recognition of Fair Financing provisions before all the corresponding revenue is realized. With the increasing scale of the Fair Financing portfolio combined with our plan to offload part of the portfolio, we expect the temporary impact on profitability to begin reversing in the coming quarter.

Financial outlook Klarna remains on a clear and steady path to profitability, reflected in our 2025 financial outlook, which anticipates continued expansion across GMV, revenue, and transaction margin dollars. Outlook for Q4’25 • GMV: $37.5–38.5 billion • Revenue: $1,065–1,080 million • TMD: $390–400 million The following USD foreign exchange rates are assumed for the guidance period: • EUR: 1.17 • SEK: 0.107 • GBP: 1.35 Klarna’s growth remains disciplined, data-driven, and scalable. With AI enhancing efficiency and our network expanding globally, we are well positioned for sustained, profitable growth. We do not attempt to provide reconciliations of forward-looking Transaction margin dollars to the comparable IFRS measure because the impact and timing of potential charges or gains excluded from the calculation of our Transaction margin dollars are inherently uncertain and difficult to predict and are unavailable without unreasonable efforts. In addition, we believe such reconciliations would imply a degree of precision and certainty that could be confusing to investors. Such items could have a material impact on our financial performance. The financial outlook is only effective as of the date given and will not be updated or affirmed unless and until we publicly announce updated or affirmed guidance. Distribution or reference of this earnings release following the date hereof does not constitute Klarna re-affirming guidance. Conference call Klarna will host a conference call and webcast to discuss its third quarter 2025 financial results on November 18, 2025, at 8:30 am ET. Participating on the call will be: • Sebastian Siemiatkowski, Chief Executive Officer, • Niclas Neglen, Chief Financial Officer, and • Andrea Ferraz, Head of Investor Relations and Corporate Development The conference call will be webcast live on Klarna’s investor relations website at investors.klarna.com. A replay will be available on the same website following the call. 7

Definitions Like-for-like (LfL) growth Year-over-year change on a like-for-like basis is calculated by adjusting the relevant metric for (1) the sale of Klarna Checkout (KCO) and (2) the impact of foreign currency fluctuations. The impact of foreign currency fluctuations is calculated by translating the reported amounts in the current period using the exchange rates in use during the comparative prior period. Active Klarna consumers Consumers who have made a purchase or a payment using a Klarna-branded product or logged into the Klarna app within the past 12 months, calculated as of the end of that 12-month period. New merchants Refers to the net new number of merchants onboarded year-over-year. Merchants means the businesses that offer their goods and services to consumers on our network. The number of merchants presented refers to the number of unique combinations of brands (e.g., H&M) available on our network and the markets where such brands are available (e.g., Sweden). Gross merchandise volume (GMV) The total monetary value of all completed purchases on our network in that period, excluding any additional fees and any subsequent actions (such as returns, settlements and disputes). Take rate Total revenue as a percentage of GMV. Average revenue per active consumer (ARPAC) Our total revenue for the trailing twelve months, divided by the number of active Klarna consumers over that period. Transaction margin dollars Transaction margin dollars as total revenue less total transaction costs, which consist of processing and servicing costs, provision for credit losses and funding costs. Transaction margin dollars before Provision for credit losses Transaction margin dollars as total revenue less processing and servicing costs and funding costs. Provision for credit losses (% of GMV) Provision for credit losses divided by GMV. Realized losses (% of GMV) Actual loan losses incurred during the period divided by GMV. Upfront provisions (% of GMV) Upfront provisions which primarily reflect expected losses at origination as well as changes in credit risk of on-book loans, divided by GMV. Adjusted operating profit (loss) Adjusted operating profit (loss) is defined as operating profit (loss) excluding (i) depreciation, amortization and impairments, (ii) share-based payments expense, (iii) restructuring costs and expenses related to preparation for an initial public offering. 9

Non-IFRS measures and reconciliations We use certain non-IFRS financial measures to supplement our consolidated financial statements, which are presented in accordance with IFRS. These non-IFRS financial measures include Transaction margin dollars, Transaction margin, Adjusted operating profit (loss), Adjusted operating expenses and Adjusted operating margin. We use these non-IFRS financial measures to facilitate the review of our operational performance and as a basis for strategic planning. We also present period-over-period changes in certain metrics on like-for-like (LfL) basis, which is calculated by adjusting the metric for (1) the sale of KCO and (2) the impact of foreign currency fluctuations. The impact of foreign currency fluctuations is calculated by translating the reported amounts in the current period using the exchange rates in use during the comparative prior period. Transaction margin dollars and Transaction margin are key performance measures used by our management to measure our ability to attain efficiency and scale and to grow these metrics over time. They measure our success in growing revenue while effectively managing our processing and servicing costs, provision for credit losses and funding costs. In addition, by excluding certain items that are nonrecurring or not reflective of the performance of our normal course of business, we believe that Adjusted operating expenses, Adjusted operating profit (loss) and Adjusted operating margin provide meaningful supplemental information regarding our performance. Accordingly, we believe that these non-IFRS financial measures are useful to investors and others because they allow investors to supplement their understanding of our financial trends and evaluate our ongoing and future performance in the same manner as management. However, there are several limitations related to the use of non-IFRS financial measures as they reflect the exercise of judgment by our management about which expenses are excluded or included in determining these non-IFRS measures. These non-IFRS measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with IFRS. Other companies, including companies in our industry, may calculate these non-IFRS (or similar non-GAAP) financial measures differently or not at all, which reduces their usefulness as comparative measures. Transaction margin dollars is defined as total revenue less total transaction costs, consisting of processing and servicing, provision for credit losses and funding costs. Transaction margin is calculated by dividing Transaction margin dollars by our total revenue. Adjusted operating profit (loss) is defined as operating profit (loss) excluding (i) depreciation, amortization and impairments, (ii) share-based payments expense, (iii) severance-related restructuring costs and (iv) expenses related to the preparation of the initial public offering (IPO). Adjusted operating expenses are defined as operating expenses excluding (i) depreciation, amortization and impairments, (ii) share-based payments expense and (iii) severance-related restructuring costs. Adjusted operating margin is defined as Adjusted operating profit (loss) divided by our total revenue. Depreciation, amortization and impairments below include amounts recorded within Technology and product development expenses in our consolidated statements of profit and loss. We consider the exclusion of certain nonrecurring or noncash items in calculating Adjusted operating profit (loss), Adjusted operating margin and Adjusted non-transaction-related operating expenses to provide a useful measure for investors and others to evaluate our operating results and expenses in the same manner as management. Revenue, Transaction costs and adjusted operating expenses for the three months ended 30 September 2025 have been adjusted to reflect the divestment of KCO completed October 1, 2024. 10

To better reflect underlying trends, we present like-for-like figures that exclude both KCO and FX effects. In Q3’25, total revenue excluding KCO grew 32%. 5 p.p. of this growth was driven by changes in FX rates, which equates to 26% like- for-like growth. Adjusted operating expenses on the other hand grew by 25% at the headline level, but only 18% on a like-for-like basis, with 7 p.p. of the increase in Q3’25 due to FX. 12 6 Like-for-like (LfL) year-over-year growth is calculated by adjusting for (1) the sale of Klarna Checkout (KCO) and (2) the impact of foreign currency fluctuations. The impact of foreign currency fluctuations is calculated by translating the reported amounts in the current period using the exchange rates in use during the comparative prior period.

Klarna delivers record-breaking Q3 as AI-powered digital bank: $903 million in revenue and 4 million card sign-ups in 4 months New York - November 18, 2025 – Klarna, the global digital bank and flexible payments provider, reported record results in its first quarter as a public company, surpassing analyst expectations. The company expects to exceed $1 billion in revenue in Q4 2025, its first billion-dollar quarter. Sebastian Siemiatkowski, CEO & Co-Founder, said: “Q3 was our strongest quarter ever — proof that our AI-driven model is working at scale, with U.S. revenue up 51% and GMV up 43%. The Klarna Card has taken off with four million sign-ups in four months, and Fair Financing continues to gain market share. While accounting timing creates a short-term profitability lag, we expect transaction margin dollars to increase by over $100 million in Q4 as revenue compounds.” Q3 Highlights: • Revenue $903 million (+26% LfL, +28% reported) – a record high • GMV $32.7 billion (+23% LfL, +43% U.S.) • Klarna Card 4 million signups since July – accounting for 15% of global transactions in October • 27 million new users and record 235,000 new merchants, reaching 850,000 in total • Fair Financing +244% U.S. GMV – strong market share gains Klarna Card — a global success The debit-first Klarna Card has attracted four million signups since July, becoming one of our fastest- growing products globally. The card combines debit and credit in one product - transparent terms, no hidden fees, consumer control, proving Klarna’s vision of next generation banking resonates globally. By October, card transactions accounted for 15% of all Klarna transactions. Another one million consumers joined Klarna’s membership program for premium benefits without credit-card debt. U.S. momentum accelerates The U.S. led Klarna’s growth with GMV +43%, revenue +51%, and Klarna is now three times larger than the nearest competitor in Pay in 4 volume, and is uniquely positioned to scale Fair Financing profitably across its ecosystem. Fair Financing — strategic investment in taking market share U.S. Fair Financing GMV rose 244% YoY, offering transparent, fixed-term installments. Per standard accounting rules, provisions for credit losses are recognized upfront while revenue compounds over time creating an expected short-term profitability lag (provisions now, revenue later). Transaction margin dollars on a realized credit loss basis and excluding the sale of KCO grew 25% in Q3 and we expect a ~$100 million uplift in Transaction Margins in Q4 as revenue compounds. AI efficiency gains: Realized losses down, operational leverage up More consumers are paying on time or even early than ever before. Realized losses fell to 0.44% of GMV, evidence that our underwriting is working and improves with additional data. We have now underwritten half a trillion in volume over 20 years. Klarna continues to improve operational leverage through AI. Since 2022, revenue per employee has tripled, while adjusted operating expenses rose just 2%. Forward-flow agreements add $6.5b in capital-light capacity, with $1.2b receivables sales expected in Q4.

Outlook Hot on the heels of a record Q3, Klarna expects an even stronger Q4. Outlook for Q4 2025: GMV $37.5–38.5b, Revenue $1,065–1,080b, TMD $390–400m.

Words such as "believe," "expect," "anticipate," "intend," "plan," "will," "may," "could," "estimate," and similar expressions identify forward- looking statements. These forward-looking statements are subject to risks, uncertainties, and assumptions that could cause actual results to differ materially from those expressed or implied. Forward-looking statements reflect our views as of the date of this release and are based on information currently available to us. We undertake no obligation to update any forward-looking statements, except as required by law. Actual results may differ materially from those anticipated. Investors should not place undue reliance on these forward-looking statements and should review the risk factors in our filings with the SEC for a more complete discussion of risks. Non-IFRS Measures and Reconciliations Transaction margin dollars is a non-IFRS measure used by our management to measure our ability to attain efficiency and scale. Transaction margin dollars is defined as total revenue less total transaction costs, consisting of processing and servicing, provision for credit losses and funding costs. Please refer to the accompanying earnings release for more information. We do not attempt to provide reconciliations of forward-looking Transaction margin dollars to the comparable IFRS measure because the impact and timing of potential charges or gains excluded from the calculation of our Transaction margin dollars are inherently uncertain and difficult to predict and are unavailable without unreasonable efforts. In addition, we believe such reconciliations would imply a degree of precision and certainty that could be confusing to investors. Such items could have a material impact on our financial performance.
