Jim Anderson, CEO, said, “After meeting with many of our employees and customers, I am more excited today about Coherent’s potential than when I joined two months ago. Coherent is a deeply innovative company with many secular growth opportunities. While we have many strengths, we also have opportunity for improvement, and I look forward to working with all my Coherent teammates to unlock the full potential of the company and drive outstanding shareholder value creation.”

Rich Martucci, Interim CFO, said, “Fourth quarter fiscal 2024 revenue increased by 9% on a sequential basis primarily driven by ongoing AI-related strength in our Datacom transceiver business. Our strong sequential revenue growth together with a GAAP gross margin improvement of 255 basis points and non-GAAP gross margin improvement of 145 basis points drove a sequential increase in GAAP and non-GAAP operating margin.”

⁽¹⁾ The Company has disclosed financial measurements in earnings release that present financial information considered to be non-GAAP financial measures. These measurements are not a substitute for GAAP measurements, although the Company’s management uses these measurements as an aid in monitoring the Company’s on-going financial performance. The non-GAAP net earnings attributable to Coherent Corp., the non-GAAP diluted earnings per share, the non-GAAP operating income, the non-GAAP gross margin, the non-GAAP internal research and development, the non-GAAP selling, general and administration, the non-GAAP operating expenses, the non-GAAP interest and other (income) expense, and the non-GAAP income tax (benefit), measure earnings and operating income (loss), respectively, excluding non-recurring or unusual items that are considered by management to be outside the Company’s standard operation and excluding certain non-cash items. EBITDA is an adjusted non-GAAP financial measurement that is considered by management to be useful in measuring the profitability between companies within the industry by reflecting operating results of the Company excluding non-operating factors. There are limitations associated with the use of non-GAAP financial measures, including that such measures may not be entirely comparable to similarly titled measures used by other companies, due to potential differences among calculation methodologies. Thus, there can be no assurance whether (i) items excluded from the non-GAAP financial measures will occur in the future or (ii) there will be cash costs associated with items excluded from the non-GAAP financial measures. The Company compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by providing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures. Investors should consider adjusted measures in addition to, and not as a substitute for, or superior to, financial performance measures prepared in accordance with GAAP. All non-GAAP amounts exclude certain adjustments for share-based compensation, acquired intangible amortization expense, restructuring charges (recoveries), integration and site consolidation expenses, integration transaction expenses, start-up costs related to the start-up of new devices for new customer applications, and various one-time adjustments. See Table 8 for the Reconciliation of GAAP measures to non-GAAP measures.
