Liquidity Forecast: Incremental Liquidity Requirement (1) § Diebold’s Risk-Adjusted Forecast projects a ($190) million trough cash shortfall in September 2023, Incremental liquidity implying a total incremental operating liquidity need of at least $390 million prior to transaction costs will ensure that Diebold is positioned – Figures incorporate repayment of the FILO and associated economics; however, assume continued to address seasonal access to the ABL facility, with slight organic expansion of the borrowing base expected through working capital September requirements – Liquidity requirement is predominantly driven by working capital and debt service, which largely consists of May and August interest payments on the Superpriority and Extended Term Loans (~$54 million total) and July coupon payments on the 1L Notes (~$51 million) Liquidity Forecast: Incremental Liquidity Requirement Figures do not include transaction costs $192 ($260) ($190) ($15) ($127) $19 ($390) Unlevered Free Cash Flow bridge ($200) detailed on page 8 Replace ($200) ABL March BoP March - Other Debt Service Borrowing Base September EoP Target Minimum Incremental Liquidity September Capacity Growth Cash Cash Liquidity Need ULFCF Notes: (1) Based on the Risk-Adjusted Forecast as further discussed 10 beginning on page 20

2023 Base Case vs. October 2022 Plan § 2023 Product revenue ~$6mm lower vs. October 2022 Plan − 62k ATM revenue units vs. 60k in October 2022 Plan (+2k units) (1) − 39k SCO revenue units vs. 38k in October 2022 Plan (+1k units) − 125k EPOS revenue units vs. 134k in October 2022 Plan (-9k units) § 2023 Services revenue ~$50mm lower vs. October 2022 Plan − Significant drivers include: Revenue • Banking cBase erosion in Europe of 5% vs. expected to remain flat in October 2022 Plan • Banking cBase in North America and LatAm growing low single digits in line with October 2022 Plan; APAC and MEA cBase low single digit erosion in line with October 2022 Plan • Retail Product Related Services (PRS) $10M unfavorable to October 2022 Plan due to flattish legacy Retail service (EPOS) § Key drivers of the ~$68mm lower 2023 Adj. EBITDA forecast include: − Lower Product margins of ~180bps ($29mm) mainly on banking side - significant portion attributable to unfavorable mix, including higher modeled shipments to LatAm Adjusted EBITDA − Lower Service margins of 50bps ($11mm) – mainly driven by underperformance in 1Q23 (130bps) as a result of higher costs and penalties incurred, 2H23 weighted savings, as well as unabsorbed infrastructure. Q2 - Q423 margin growth to partially offset 1Q23 miss Note: 34 (1) As compared to historical public filings, SCO Revenue Units has been revised to include the sale of kiosks, which are similar in price / function to SCO devices. This change is consistent with how management is analyzing the business. Excluding kiosks included in the October 2022 plan, 2023 SCO revenue units would be 35k.

Supplementary Information § Revised Forecast Margin Variance Drivers: The October Cleanse Model assumed approximately $5 million of DN Series margin improvement. Diebold closed 2022 with 13.6% Product margins versus Cleanse Model expectations of 15.7% - effectively resulting in a ~200 basis point lower starting point in 2023. Margins are also impacted by unfavorable mix as a result of a higher mix of LATAM / APAC (2-3k India units) machines § SG&A Cost Savings: The biggest benefit to SG&A relative to the October Cleanse Model is lower than anticipated AIP / LTIP expense. The Cleanse Model assumed a ~20% reduction to AIP / LTIP - whereas the Base Case assumes 30% / 50%, respectively. R&D is $6 million favorable relative to the Cleanse Model, which reflects incremental efficiencies as it relates 1) project rd rationalization (focus on highest yielding projects) 2) offshoring 3) lower 3 party spend § ‘Other Cash Flow’ Composition: Payroll and Benefits Liabilities ($20 million), Pension and Postretirement Benefits ($14 million), Net VAT and Sales Tax ($8 million), Warranty ($(2) million), Other Balance Sheet Timing ($3 million), and Assets-Held-for-Sale ($5 million) § EPOS Units Shipment Plan: EPOS is a shorter turn business (30-60 days) and therefore it is not unusual to have a sizable unscheduled figure one quarter out. Approximately 90% of Q2 shipments have been confirmed / shipped from the facility EPOS Units – Shipment Plan 37.5k 36.0k 28.1k 3.3k 23.3k 31.0k 34.3k 21.6k 5.0k 3.2k 3.2k Q1 Q2 Q3 Q4 Unscheduled Orders Scheduled Orders Shipments 38

Supplementary Information (cont’d) § 2024 and 2025 Product and Service Revenue Growth Drivers: – 2024 Product: 64k ATMs, 43k SCOs, 120k EPOS units – 2024 Services: Low single digit Banking cBase decline offset by higher mix of recyclers / pricing and inflationary growth in PS / M&S. Continued growth in Retail SCO cBase (90% attach of Services) – 2025: Inflationary ATM / EPOS growth and continued SCO penetration. Flattish Banking cBase / inflationary growth and continued SCO cBase growth § 2024 and 2025 Product Margin Expansion Drivers: 20-25 basis points of Product margin expansion is driven by increased procurement / supply chain efficiency § 2024 and Long-Term Operating Expense Efficiencies and Wage Inflation: – 2024 assumes flat operating expenses, which is driven by ~4% labor inflation being offset by ~$15 million of efficiencies – 2025-2028 assumes 1% net operating expense inflation, which is driven by ~4% labor inflation being offset by ~$10 million of efficiencies § Recurring Cash Flow Adjustment Detail: The Other Cash Flow Adjustments item represents a combination of the Diebold's contribution to its pension fund, collection of cash related to the Diebold's finance lease receivable portfolio, deferred costs on the balance sheet, and other miscellaneous balance sheet account movements § Unlevered Free Cash Flow Bridge Detail: – $47 million of restructuring and refinancing costs which represents ~$17 million of professional fees expected to be incurred in connection with the ongoing restructuring process – $4 million of redundancy costs – $26 million of severance costs 39

Supplementary Information (cont’d) § Services Volume Forecast Detail and Market Dynamics: – North America: Fairly stable overall despite a few notable deconversions, the largest being Cardtronics – LATAM / Brazil: Both strong cBase growth markets for DN growing volume ~3% annually – Europe: Declined approximately 5% annually. Largely a function of general branch / ATM consolidation as well as network / utility models – APAC: Declined at a high-single rate the past few years. Largely a function of country-specific nationalization initiatives, India run-off and general competitiveness in the region. Diebold sees an opportunity over time to regain some of the lost India cBase as it begins selling back into the country § cBase Variance Detail: SCO units have a 90%+ attach rate of Services and 90%+ are net new units to installed base - thereby driving a compelling Retail Services growth story (+6% 2023 / +5% 2024 - Base Case model). Market dynamics outlined above are also drivers of the Retail Services business growth § Backlog Composition Detail: Vast majority of Banking's revenue is secured by its $1.1 billion of Backlog (February 2023 ending backlog), which represents ~90% of March - December Base Case product revenue. ~67% of Retail's March - December 2023 Base Case product revenue is secured by February ending backlog 40

The Company assumes no obligation to update any forward-looking statements, which speak only to the date of the Materials. Non-GAAP Financial Measures and Other Information: To provide investors with additional information regarding our financial results, the Company discloses certain financial measures that are not prepared in accordance with GAAP, including levered free cash flow/(use) and unlevered free cash flow/(use) and adjusted EBITDA. The Company uses these non-GAAP financial measures, in addition to GAAP financial measures, to evaluate our operating and financial performance and to compare such performance to that of prior periods and to the performance of our competitors. Also, the Company uses these non-GAAP financial measures in making operational and financial decisions and in establishing operational goals. The Company also believes providing these non-GAAP financial measures to investors, as a supplement to GAAP financial measures, helps investors evaluate our operating and financial performance and trends in our business, consistent with how management evaluates such performance and trends. The Company also believes these non-GAAP financial measures may be useful to investors in comparing its performance to the performance of other companies, although its non-GAAP financial measures are specific to the Company and the non-GAAP financial measures of other companies may not be calculated in the same manner. We provide adjusted EBITDA because we believe that investors will find adjusted EBITDA to be a useful measure for evaluating our operating performance and comparing our operating performance with that of similar companies that have different capital structures and for evaluating our ability to meet our future debt service, capital expenditures and working capital requirements. We consider free cash flow (use) to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the purchase of property and equipment and capitalized software development, changes in cash of assets held for sale and the use of cash for M&A activities, and excluding the use/proceeds of cash for the settlement of foreign exchange derivative instruments, can be used for debt servicing, strategic opportunities, including investing in the business, making strategic acquisitions, strengthening the balance sheet and paying dividends. Unlevered free cash flow (use) provides incremental visibility into the Company’s liquidity by excluding cash used for interest payments and other debt servicing from free cash flow (use). 41
