Company Reaffirms Full Year 2025 Financial Guidance

Qnity Electronics, Inc. ("Qnity") (NYSE:Q), a premier technology solutions leader across the semiconductor value chain, today announced that Matt Harbaugh has stepped down from his role as Chief Financial Officer due to health reasons. Mike Goss, the Company's current Principal Accounting Officer and Controller, has been appointed to serve as Interim Chief Financial Officer, effective immediately. The Company will conduct a comprehensive search for the position.

"Matt's leadership and deep experience guiding complex spin‑offs have been valuable as we transitioned into a new independent company," said Jon Kemp, Qnity's Chief Executive Officer. "On behalf of the entire team, we wish him well and fully support his decision to focus on his health."

"It has been a privilege to work alongside this strong management team to launch Qnity," said Matt Harbaugh. "I remain confident in the company's continued success and strategy for value creation."

Stepping into this interim role, Mike brings nearly three decades of finance experience across several disciplines. Prior to serving as Qnity's Principal Accounting Officer and Controller, Mike spent 14 years at DuPont where he held multiple senior roles. During this time, he gained significant expertise in portfolio transformation and financial operations rigor, most recently serving as Vice President, Principal Accounting Officer and Controller, from December 2018 to October 2025. Prior to DuPont, Mike held various roles at Ernst & Young.

"Mike is a seasoned financial leader recognized for his experience across core disciplines and a proven track record of leading financial operations to drive strategic growth, company performance, and long-term value," said Kemp. "His deep understanding of our business and financial operations will ensure a smooth transition as we continue to execute against our strategic priorities."

Reconciliation of 2025 Financial Guidance

Non-GAAP Financial Measures

1. Net Sales has been derived from our historical combined financial statements, which were prepared on a carve-out basis as we did not operate as a stand-alone entity in 2024 or during the period ended September 30, 2025. The estimated forecast financial information and metrics presented have been voluntarily provided and reflect Qnity on a projected standalone basis.
2. Reflects a management adjustment to give effect to the Spin-Off of Qnity into an independent, publicly traded company, for the twelve months ended December 31, 2024 and December 31, 2025. The adjustment is not reflected net of tax. This is incremental to corporate costs reflected in the Carve-Out Adjusted Operating EBITDA.
3. For the purpose of 2025E full year estimated results, we have included the full amount of interest expense in the pro forma results. A portion of this expense will be reflected in Carve results due to the issuance of the Senior Secured Notes and Senior Unsecured Notes in August 2025 and the Senior Secured Term Loan Facility entered into at the time of spin.
4. Carve-out & Pro forma Other Expenses include nonoperating pension / OPEB benefits / charges, foreign exchange gains / losses, net, and significant items including litigation/ environmental/legal costs, and restructuring expense.
5. Carve-Out Adjusted Operating EBITDA is a non-GAAP financial measure and is defined as earnings (i.e., "Income before income taxes") before interest, depreciation, amortization, non-operating pension / OPEB benefits / charges, foreign exchange gains / losses, indirect legacy costs, and adjusted for significant items.
6. Adjusted Pro Forma Operating EBITDA is a non-GAAP financial measure and is defined as Pro Forma earnings (i.e., " Pro Forma Income before income taxes") before Pro Forma adjustments related to interest, depreciation, amortization, non-operating pension / OPEB benefits / charges, foreign exchange gains / losses, indirect legacy costs, and adjusted for significant items. Includes the pro forma and management adjustments expected to be incurred annually following spin-off related to stand-alone public company costs.
