Letter from our Chair and Chief Executive Officer

Dear Shareholders:

Thank you for your investment in ScanSource. On behalf of ScanSource’s Board of Directors, it is my pleasure to invite you to participate in the upcoming 2026 Annual Meeting of Shareholders and encourage you to review the attached Notice of Annual Meeting of Shareholders and Proxy Statement and vote using the attached proxy card.

I want to take this opportunity to share the Board’s priorities for creating long-term shareholder value and to highlight some important developments at ScanSource this year:

Our Performance in Fiscal 2026: Our strategy is focused on driving profitable revenue growth as we continue to shift our business toward a higher-margin, higher-recurring revenue model, with a focus on free cash flow. For our full year results, we delivered higher net sales, gross profit and earnings, expanded gross profit margins and generated strong free cash flow. Full year net sales increased 6.1% to $3.23 billion, reflecting renewed growth for key technologies in the second half of the year. Gross profit of $437.4 million and adjusted EBITDA* of $151.5 million grew by 7.0% and 4.8%, respectively. Gross profit margin increased 20 basis points year-over-year to 13.6%. For the full year, the percentage of gross profits from recurring revenue increased to 33.7% from 32.8% for the prior year. Non-GAAP net income* of $91.9 million increased 8.0% over last year, and full year free cash flow* of $113.8 million represented 124% of ournon-GAAP net income. Non-GAAP EPS* of $4.24 increased 18.8% year-over-year, including the benefit of share repurchases totaling $97.9 million. Our balance sheet strength continued. We ended fiscal 2026 with $88.4 million in cash and generated $123.1 million of operating cash flow. Adjusted ROIC* for the year increased to 14.7%.

We are accelerating the future of technology distribution, leading the channel and connecting our partners with innovative solutions. Our multiple sales channels are a key competitive advantage for ScanSource with our suppliers as they seek new routes to market. In May 2026, we launched a Converged Communications business unit that brings together our Specialty Communications and Intelisys CX cloud-based solutions teams. This new business unit is designed to help solution providers sell more cloud recurring revenue and Intelisys partners add hardware to their solutions.

In September 2026, we completed our acquisition of MicroAge, a leading IT solutions integrator, managed services provider and digital transformation partner. Consistent with our strategy, the acquisition adds higher-margin capabilities and expands our reach in strategic growth technologies, including cloud, cybersecurity, data center and AI, while creating new opportunities to support our channel partners as they address increasingly complex customer needs. We expect the acquisition to be accretive to gross profit margin, adjusted EBITDA margin andnon-GAAP EPS* in the first year following close.

Looking Ahead to Fiscal 2027: We are excited about the growth opportunities ahead for our channel partners and the expanding role for ScanSource as a differentiated leader in a converging technology ecosystem. The convergence of IT, connectivity, and cloud computing is redefining success in technology distribution. We are well positioned to build cutting-edge skills, capabilities, and expertise to excel in a device-connected, cloud-driven world. We believe IT decision makers face increasing complexity given the need for integration and the number of solutions, especially as technologies like AI are part of the solution.

Together with our investments in the business and capabilities added through acquisitions, this approach supports our strategy to serve channel partners across hardware, SaaS, connectivity and cloud services. As we execute our strategic plan, our capital allocation priorities remain to invest in our business, evaluate acquisitions with discipline and continue share repurchases while maintaining a strong balance sheet.

In summary, we have a successful, long-term strategic plan combined with an amazingly strong people culture led by a highly engaged Executive Leadership Team.

Board Composition: Overseeing our business is a Board that is actively engaged in ensuring that management develops and executes our differentiated technology distribution strategy. Our Board consists of a group of highly skilled directors with diverse backgrounds who bring knowledge, experience and enthusiasm to the Company and are committed to driving long-term value for our shareholders.

Earlier this year, Peter Browning retired from our Board after more than twelve years of service. We thank Peter for his leadership and many contributions to ScanSource. Charlie Mathis now serves as our Lead Independent Director, bringing extensive financial leadership and acquisition experience, together with a deep understanding of ScanSource’s business.

People and Culture: The Company and the Board believe that our purpose remains clear: to serve as a trusted partner, delivering exceptional value for our channel partners and suppliers. This commitment is brought to life each day through the dedication and expertise of our people, which is our competitive advantage. Guided by our core values and aligning our strategies with evolving customer needs, we help our partners thrive in dynamic technology markets. Our people and culture are at the heart of ScanSource’s success.

In fiscal 2026, we continued to invest in employee engagement, training and development. Employees completed more than 600 unique trainings, and we introduced an artificial intelligence (“AI”) channel through The Hub, our global learning platform, to accelerate responsible AI adoption across the Company. Feedback from our Employee Voices survey in North America and Pulses survey in Brazil continues to help guide enhancements to our programs and processes.

These initiatives foster a more connected and collaborative workforce and help develop the skills and capabilities our people need as we execute our strategy and pursue future growth opportunities.

Corporate Citizenship: Giving back to our communities is a core value at ScanSource. Over the past year, we continued to expand our Impact 360 program, a partnership focused on supporting underserved schools through hands-on volunteerism, relationship-building and needs-based programming. Impact 360 has expanded to more than a dozen schools across ScanSource’s footprint and received a Silver Halo Award for Best Education Initiative from Engage for Good. During 2025, more than 400 ScanSource volunteers contributed more than 2,000 hours to support our communities. Looking ahead, we remain focused on the corporate citizenship priorities that matter most to our business and stakeholders. Leading with our people and guided by our core values, we are committed to advancing sustainable growth and building long-term resilience for ScanSource.

Shareholder Engagement Efforts: Engaging with our shareholders and considering their views as we make decisions is an important part of the Board’s commitment to strong corporate governance. Our engagement efforts focus on building relationships, expanding dialogue to cover strategy and governance topics and collecting shareholder feedback. Over the past year, we reached out to shareholders representing nearly 70% of shares outstanding and held engagement calls with some of our largest shareholders, representing approximately 60% of shares outstanding. This dialogue helps us to better understand shareholders’ views on a variety of relevant issues, including Company strategy and performance, Board composition and refreshment, executive compensation and governance practices. The Board continues to encourage you to share your opinions with us.

We look forward to the year ahead, and, on behalf of the Board, thank you for your continued support.

Best regards,

Chair and Chief Executive Officer
