Adjusted EBITDA for the quarter amounted to SEK 4.9 million, reflecting continued profitability in a period with lower revenues compared with the same quarter last year. The development was influenced by substantial negative currency effects, which reduced reported net sales by SEK 5.9 million and, in turn, affected profitability. At the same time, our disciplined cost base and scalable business model continued to support resilient EBITDA. Total license revenues excluding currency effects amounted to SEK 30.2 million. While lower year on year, this reflects a combination of timing in the license business and a particularly strong comparison quarter last year. Importantly, the underlying fundamentals of our license model remain solid, supported by stable partner relationships, ongoing commercial activity, and continued expansion of the clinical and regulatory evidence base for our technology. Our partnership with BD continues to develop positively. Although revenues in the quarter were lower than last year, the collaboration is progressing well and remains strategically important for both parties. Sales of Bactiguard-coated products have now begun in parts of Europe, and preparations are underway for further expansion into additional European markets. The close and constructive dialogue between our teams, combined with increasing market presence, reinforces our confidence in the long-term growth potential of the partnership. For Zimmer Biomet, the first quarter represents the first reported period under the updated business setup for the ZNN Bactiguard trauma nail system. During the quarter, focus was on advancing the MDR transition in Europe and continuing postmarket clinical studies. These activities are essential to support future commercial development and to gradually increase transparency around inmarket performance. Beyond the operational progress, the collaboration with Zimmer Biomet is characterized by a strong and forward-looking working relationship, with shared commitment to strengthening both the clinical and regulatory position of Bactiguard- coated trauma implants. The Wound Management portfolio generated revenues of SEK 18.2 million, excluding currency effects, which is lower than the strong first quarter last year but still represents a solid performance. Hydrocyn aqua remains the main contributor, supported by ongoing distributor onboarding, entry into additional markets, and encouraging feedback on demand and clinical relevance. We continue to see Wound Management as an important complementary growth driver with clear potential to deliver profitable growth over time. A key priority during the quarter was continued investment in regulatory-related activities to support future market approvals. Clear and well defined regulatory pathways are central to our value proposition for both existing and new partners. Our work to clarify and advance regulatory routes, including those related to the US FDA, is aimed at reducing complexity, shortening development timelines, and increasing the attractiveness of Bactiguard’s technology across multiple therapeutic areas. In parallel, the ongoing MDR process with Zimmer Biomet remains a critical enabler for sustained growth in orthopedic trauma. In addition, we maintained a high level of business development activity across our strategic therapeutic areas. Through broad engagement with potential partners, clinicians, and industry stakeholders, we continue to build visibility, validate interest, and progress early-stage opportunities that support our long-term growth ambitions. Strengthening the leadership team During the quarter, we also strengthened our leadership team to support the next phase of Bactiguard’s development. In addition to the existing competences in the management in our core technology areas, we have added Communications, Business Development & Alliance Management, Regulatory & Quality, and Wound Management in our most senior leadership. We have been able to achieve this through a combination of external recruitment and internal promotion and this team represents our capabilities in areas that are critical to executing our strategy and supporting continued growth. ===== SIDA 3 ===== INTERIM REPORT FIRST QUARTER 2026 | 3 Outlook Infection prevention remains a critical global healthcare priority, and the relevance of Bactiguard’s technology continues to increase. While quarterly revenues will vary due to currency movements, regulatory timing, and the nature of license agreements, our strategic direction is unchanged. We will continue to strengthen partnerships, advance regulatory pathways, deepen business development activities, and drive profitable growth in Wound Management. With a solid foundation in place, we remain confident in our ability to create long-term value through disciplined, step-by-step execution of our strategy. Christine Lind CEO ===== SIDA 4 ===== INTERIM REPORT FIRST QUARTER 2026 | 4 Business model Bactiguard is a global MedTech company developing safe and biocompatible technology to prevent medical device related infections. The company’s unique technology is based on an ultra-thin noble metal coating that prevents bacterial adhesion and biofilm formation on medical devices. Bactiguard’s infection prevention solutions decrease patient suffering, save lives, and unburden healthcare resources while also fighting against antimicrobial resistance, one of the most serious threats to global health and modern medicine. Bactiguard operates through license partnerships with leading global MedTech companies that apply the infection prevention technology to their medical devices and sell them under their own brand or co-branded with Bactiguard. Our license-focused business model is scalable with operational leverage. Partnerships across three phases Bactiguard’s license revenues have three components: revenues for coating and process development, revenues for the right to use the coating technology on medical devices within a specific application and geographical area, and royalties – a variable remuneration once the license partners’ products reach the market. The revenues are generated across three partnership phases: application development, exclusivity and license. An application development partner works in close collaboration with Bactiguard’s R&D team exploring the application of our infection prevention technology to the partners’ underlying device to enhance its performance. The nature of development work means that not every project will succeed, but the learnings are valuable for other application areas. An exclusivity partner gets exclusive rights to apply our coating technology to a certain medical device but has no products in the market yet, for instance due to pending regulatory approvals, which can take time depending on the type of application and its classification. A license partner has the right to market and sell medical devices with Bactiguard’s coating technology, in a certain region or globally. Not all partnerships will follow all three phases. An agreement with a partner can generate revenues from separate phases and components simultaneously.

Financial targets The company’s financial targets relate to growth and profitability and are expected to be delivered by year-end 2030. The financial and strategic targets should not be perceived as a forecast but rather reflect what Bactiguard’s Board of Directors and Executive Management consider to be reasonable mid-term expectations given the sharpened license focused strategy. Revenues: deliver revenues of at least SEK 600 million by year-end 2030 EBITDA: deliver an EBITDA of at least SEK 200 million by year-end 2030 Partnership development: have at least ten application areas in either exclusivity partnerships or license partnerships by year-end 2030 Other information Accounting and valuation principles The consolidated financial statements are prepared in accordance with the International Financial Reporting Standards (IFRS). The interim report has been prepared in accordance with IAS 34 Interim Reporting and the Annual Accounts Act. Disclosures in accordance with IAS 34 Interim Reporting are submitted both in notes and elsewhere in the interim report. The parent company’s financial statements have been prepared in accordance with the Annual Accounts Act and the Swedish Corporate Reporting Board's recommendation, RFR 2 Accounting for Legal Entities. Accounting and valuation principles are stated in the annual report 2025. The accounting principles are unchanged from previous periods. Segment reporting An operating segment is a component of an entity that engages in business activities from which it may derive revenues and incur expenses, whose operating results are regularly reviewed by the chief operating decision maker and for which there is separate financial information. The company's reporting of operating segments is consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker is the function that assesses the operating segment performance and decides how to allocate resources. The company has determined that the Group’s executive management constitutes of the chief operating decision maker. The company is considered in its entirety to operate within one business segment. Parent company During the period, the parent company has received compensation for services and interest in its receivables from group companies. No investments were made during the period. Risk factors Companies within the Group are exposed to various types of risk through their activities. Bactiguard continually engages in a process of identifying all risks that may arise and assessing how each of these risks shall be managed. The Group is working to create an overall risk management program that focuses on minimizing potential adverse effects on the company's financial results. The company is primarily exposed to financial risks, market risks and operational risks. A description of these risks can be found on page 14-15 and 57–59 in the annual report 2025. The geopolitical situation and macro trends In addition to identified risks, the macro situation and its impact is continuously monitored. The global healthcare challenges have a significant impact on society. The need for more efficient and safe healthcare is driven by both economic and demographic developments, as well as increased political unrest, conflicts, wars, and natural disasters. Particularly prominent are healthcare-associated infections and antimicrobial resistance where we see an increased interest in infection prevention. ===== SIDA 9 ===== INTERIM REPORT FIRST QUARTER 2026 | 9 Bactiguard does not have suppliers in or sales to any of Russia, Belarus, or Ukraine. However, the global economy is affected by the situation of the war, and we follow developments closely and continuously evaluate the operational and financial effects as the global situation may change and affect the company's financial position. Bactiguard has a subsidiary in Israel. We are closely following the developments there and our primary focus is to ensure the staff’s well-being and security. We make the assessment that the conflict in Israel will have a negligible effect on the group’s result and financial position. While we see falling inflation levels, inflation and higher prices can continue to affect the company negatively as it is not always possible to change the price to the customers, all of which can affect the financial position negatively. The falling inflation levels can lead to lower interest rates, which can positively impact the interest costs. Some countries are now in or close to recession, which can lead to a decreased ability for customers to pay their invoices. Bactiguard has substantial USD exposure in the license business, and a weaker USD will have a negative effect on the results, see the annual report 2025. The company does not hedge the currency exposure. Developments are monitored closely, given the rapidly evolving landscape. ===== SIDA 10 ===== INTERIM REPORT FIRST QUARTER 2026 | 10 Group consolidated income statement Condensed statement of comprehensive income Full year RTMTSEK Note 2026 2025 2025 2025/26Revenues1Net sales 42,448 59,053 215,918 199,313Other operating income4,457 3,687 12,849 13,619Total 46,905 62,740 228,767 212,932Change in inventory of finished goods and products in progress 4 1,273 2,618 1,349Raw materials and consumables -3,764 -12,242 -33,883 -25,405Other external expenses -15,536 -15,615 -51,595 -51,516Personnel costs -21,468 -23,128 -95,376 -93,716Depreciation and amortization -11,293 -12,020 -47,077 -46,350Other operating expenses -2,016 -3,619 -6,776 -5,173Total -54,073 -65,351 -232,089 -220,811Operating profit/loss -7,168 -2,612 -3,322 -7,879Profit/loss from financial itemsFinancial income 1,196 16 1,392 2,572Financial expenses -1,888 -4,883 -12,183 -9,188Total -692 -4,867 -10,791 -6,616Profit/loss before tax -7,860 -7,478 -14,113 -14,495Current tax -

It is the opinion of the company that these measures provide useful supplementary information to investors and the company’s management as they allow for the evaluation of the company’s performance. Since not all companies calculate the measures in the same way, these are not always comparable to measures used by other companies. These performance measures should therefore not be considered a substitute for measures as defined under IFRS. The definitions and tables below describe how the performance measures are calculated. The measures are alternative in accordance with ESMA’s guidelines unless otherwise stated. EBITDA EBITDA presents the company’s earning capacity from ongoing operations irrespective of capital structure and tax situation. The key figure is used to facilitate comparisons with other companies in the same industry. The company considers this performance measure to be the most relevant, since the company’s technology is depreciated by large amounts, which does not impact cash flow negatively. Bactiguard’s patented, unique technology can be applied to a broad range of products in the licensing business. The company defines EBITDA as operating profit/loss excluding depreciation and amortization of tangible and intangible assets. EBITDA margin Presents the company’s earning capacity from ongoing operations, irrespective of capital structure and tax situation, in relation to revenues. The key figure is used to facilitate analysis of the company’s result in comparison with comparable companies. Adjusted EBITDA Adjusted EBITDA is presented as an alternative performance measure to illustrate the underlying operating performance by excluding items affecting comparability. A reconciliation to EBITDA is provided below. The Group expects to incur non-recurring costs related to the EU Medical Device Regulations (MDR) during 2026 and 2027. These costs are not considered representative of the underlying operating performance as they do not form part of the Group’s ongoing core operations and are therefore considered non-recurring. To provide a more comparable view of performance, the Group therefore also presents adjusted EBITDA and adjusted EBITDA margin excluding these costs.

EBITDA margin % 10.5 15.0 Net debt Net debt is a measure used to describe the Group’s indebtedness and its ability to repay its debt with cash generated from the Group’s operating activities if the debts matured today. The company considers this key figure interesting for creditors who want to understand the Group’s debt situation. The company defines net debt as interest-bearing liabilities minus cash and cash equivalents at the end of the period. Equity ratio Equity ratio is a measure the company considers important for creditors who want to understand the company’s long-term ability to pay. The company defines equity ratio as equity and untaxed reserves (less deferred tax), in relation to the balance sheet total. Cash flow from operating activities per share Cash flow per share calculated as the cash flow from operating activities divided by the average number of shares outstanding during the period. The key figure is presented because it is used by analysts and other stakeholders to evaluate the company – it shows operating cash flow per share. Profit/loss from financial items Financial income minus financial expenses. Direct reconciliation against financial report is possible. RTM/Rolling 12 months This performance measure implies the twelve months before and including a certain date.

Distribution of how fair value is determined is based on three levels. Level 1: according to prices quoted on an active market for the same instrument. Level 2: based on directly or indirectly observable market data not included in level 1. Level 3: based on input data that is not observable on the market. For description of how fair values have been calculated, see annual report 2025, note 4. Fair value of financial assets and liabilities is estimated to be substantially consistent with posted values. The balance sheet contains receivables and liabilities from the business that are held to maturity. These are reported at amortized cost, which also constitutes an approximation to fair value.
