FINANCIAL HIGHLIGHTS 19 Copyright 2024, Coherent. All rights reserved.

FY24 Q2 HIGHLIGHTS $1.131 billion, above the midpoint of our $1.075 – $1.175 billion guidance. REVENUE $0.36, above the high end of our $0.14 – $0.32 guidance and up from $0.16 in the preceding quarter driven Non-GAAP EPS primarily by the strong gross margin upside, favorable operating leverage, and interest and dividend income. OPERATING $67 million, compared to $220 million in the year-ago quarter and $199 million in the preceding quarter. CASH FLOW DEBT We paid down $89 million of our outstanding debt. REDUCTION Macroeconomic uncertainty continues to impact our near-term growth and visibility; however, we saw signs of VISIBILITY improving demand trends during the quarter and expect ongoing sequential improvement in revenue growth throughout the remainder of fiscal 2024. As required by Regulation G, we have provided reconciliations of those measures to the most directly comparable GAAP measures in the section captioned “GAAP to NON-GAAP RECONCILIATION.” 20 Copyright 2024, Coherent. All rights reserved.

FY24 Q2 HIGHLIGHTS - CONTINUED We enjoyed a third straight quarter of strong orders for our AI/ML-related Datacom transceivers. Our 800G revenue increased sequentially by over 100% to cross the $100 million quarterly threshold just over one year since initial shipments, which marks one of the fastest product revenue ramps in the history of the AI/ML company. We are excited by the active engagement we have with from large customers for 1.6T transceivers and components. In response to customer demand, we continue to make progress toward expected commercial launch in fiscal 2025 of our 1.6T transceivers and components. Enhancing our confidence in the long-term outlook for our silicon carbide business, during the second quarter, we consummated the previously announced transactions with Mitsubishi Electric and DENSO SILICON Corporation pursuant to which those entities invested an aggregate of $1 billion in exchange for non- controlling ownership interests of 12.5% each in Silicon Carbide LLC, a newly formed LLC into which we CARBIDE contributed our silicon carbide business, and entered into long-term supply agreements that will support their demand for SiC substrates and epitaxial wafers. As we transform the company to improve operating performance, restructure our production footprint to STRATEGIC enhance operating resiliency, and complete the integration of legacy Coherent, Inc., we are exploring OPPORTUNITIES other strategic opportunities—not including material acquisitions—to unlock shareholder value. 21 Copyright 2024, Coherent.
