⁽¹⁾ The Company has disclosed financial measurements in this letter to shareholders 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 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 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.

EXECUTIVE SUMMARY

Revenue. $1.209 billion, above the high end of our $1.120 – 1.200 billion guidance and an approximate 7% sequential increase.

Non-GAAP Gross Margin. 35.8%, slightly below our 36 – 38% guidance and a 20 bp sequential decrease from 36.0%. New Datacom transceiver product introduction ramps, a power failure in a silicon carbide growth facility, slower than expected recovery in Telecom, and higher than expected inventory provisions in our Lasers segment collectively had an over 100 bps adverse impact.

Non-GAAP Operating Margin. 15.1%, within our 14 – 16% guidance and slightly lower than the preceding quarter.

Non-GAAP EPS. $0.53, above the high end of our $0.32 – $0.52 guidance and up from $0.36 in the preceding quarter.

Operating Cash Flow. $117 million, compared to $152 million in the year-ago quarter and $67 million in the preceding quarter.

Debt Reduction. We paid down $58 million of our outstanding debt.

Visibility. Macroeconomic uncertainty continues to impact our near-term growth and visibility. Recovery in our Telecom vertical was slower than we previously expected. We continued to see signs of ongoing improving demand trends along with favorable company-specific trends during the quarter. We expect ongoing sequential improvement in revenue growth in the fourth quarter of fiscal 2024.

AI/ML. We enjoyed a fourth straight quarter of strong demand for our AI/ML-related Datacom transceivers. Our 800G revenue increased sequentially by almost 80% to almost $200 million and is on track to exceed $250M in our fourth quarter of fiscal 2024. In response to customer demand, we are making progress toward commercial launch of our 1.6T Datacom transceivers and components in calendar 2025 and expect to ship commercial samples of 1.6T products to our customers starting in the first quarter of fiscal 2025.

◾ Restructuring, synergies, and consolidation expenses of approximately $198 – 208 million.

BIG PICTURE

In the face of what remains a challenging macroeconomic environment, for the quarter, we delivered solid sequential revenue growth, above the high end of our guidance, and implemented rigorous controls on operating expense, which came in below the midpoint of our guidance, and which together offset disappointing gross margin to drive strong sequential improvement in Non-GAAP EPS, above the high end of our guidance.

Demand

Our Datacom strength is more than offsetting slower than expected revenue growth in some other markets and verticals. We remain confident in our long-term growth prospects for each of these markets and verticals. We also saw additional positive trends in each. We emerged from the third quarter, however, relatively more cautious as to the timing of recovery in revenue growth in our Telecom vertical and as to the growth rate in fiscal 2025 for our silicon carbide revenue.

Communications Market

Datacom Vertical. We enjoyed another quarter of strong AI-related Datacom demand for our 800G Datacom transceivers. We expect this strength to continue in the current fourth quarter and into fiscal 2025.

Telecom Vertical. While the third quarter also offered signs of improving end demand in our Telecom vertical within our Communications market, Telecom recovery is slower than we previously expected, as our customers are still working down their inventory, but at a slower pace than we forecasted. Our Telecom revenue sequentially declined, albeit modestly, in the third quarter, and we currently expect sequentially flat revenue in our current fourth quarter.

Industrial Market

The third quarter offered further signs of recovery in Industrial market end demand. Our Industrial orders sequentially increased by 10% following 11% sequential growth in the second fiscal quarter, and we currently expect to end our fiscal 2024 with a third straight quarter of over 10% sequential growth. Our Industrial revenue for the third quarter and our revenue outlook for

the fourth quarter compare favorably to the sequential decline we experienced throughout fiscal 2023 and into the first quarter of fiscal 2024. A sequential decline in our Aerospace & Defense revenue, however, offset sequential growth in the other three verticals within our Industrial market to drive relatively flat sequential revenue in the third quarter. We expect healthy sequential revenue growth in our Industrial market in the current fourth quarter.

Electronics Market

Silicon Carbide. Our revenue growth outlook for our silicon carbide business is less than we previously expected as a result of supply constraints limiting our ability to ramp production. We have been supply-constrained, with our ability to ramp production having been the key constraint to silicon carbide revenue growth. We still expect to out-grow the overall silicon carbide market in both the near and longer term. We have moderated our silicon carbide revenue growth outlook for fiscal 2025, however, to take into account the industry-wide slowdown in EV demand and production.

Instrumentation Market

We remain excited regarding the long-term growth opportunity in the Instrumentation market. Near-term, demand in our Instrumentation market appears to have stabilized with a third straight quarter of just under $100 million in revenue. Elevated inventories appear to have been reduced to and may have reached normalized levels; however, we have yet to see a return to sequential or year-over-year growth, and our revenue remains approximately 15 – 20% below its fiscal 2023 level primarily due to macroeconomic uncertainty.

Margins

Driving meaningful secular improvement in our margin structure remains our primary focus. We remain confident that we will return to our previous 40% Non-GAAP gross margin and 20% Non-GAAP operating margin structure by the end of the first half of fiscal 2026 and believe that we will eventually exceed these targets. As we noted in our Shareholder Letter in the preceding quarter, we are making significant investments and are implementing numerous actions to drive this progression.

Third quarter gross margin was below our guidance, which we offset by solid operating expense controls driving operating margin above the midpoint of our guidance. Our gross margin was adversely impacted by several factors that we believe we have resolved or will resolve over the next several quarters. These factors collectively had a greater than 100 bps adverse impact on our gross margin in the quarter. They span our Datacom vertical within our Communications market, our silicon carbide business (the revenues of which are reflected within our Electronics market) and our Lasers segment.

Accordingly, we have reduced our full year fiscal 2024 Non-GAAP gross margin outlook to 35.7 – 36.3% from 36 – 38% previously. We expect to drive sequential improvement in our current fourth quarter to 36.0 – 37.5%.

We set forth below a more detailed discussion of the specific issues by segment.

6

Materials. Lower than expected yields drove our disappointing silicon carbide gross margin in the third quarter. Specifically, a power failure limited our silicon carbide substrate growth yield. The resulting lower production volume translated into lower overhead absorption. We have fully resolved the power failure. Our silicon carbide growth yields are very close to plan and production volumes are increasing with, we expect, an over 50% sequential increase in our silicon carbide revenue in our fourth quarter.

Networking. Lower than expected Datacom gross margin accounted for over 50% of the total adverse impact. Specifically, lower transceiver yields was the primary issue. We have implemented a number of corrective actions, have started to see meaningful improvement in yield, and expect to attain our targeted yield by the time we exit the first quarter of fiscal 2025.

Lasers. Lower than expected gross margin in our Lasers segment was primarily due to a number of one-off inventory provisions related to portfolio adjustments. We do not expect these to recur.

Unchanged Long-Term Outlook; Growth Bias. Our longer-term outlook for improved margin structure and strong secular growth in all of our markets remains unchanged, driven by both an eventual recovery in end market demand and the impact of AI along with other significant drivers discussed at greater length below.

We are not waiting for improved end market demand to drive enhanced profitability. We have already implemented actions across virtually all of our businesses in a drive for enhanced operating efficiency as measured by return on sales.

As discussed in our second quarter fiscal 2024 Shareholder Letter and at greater length below, some of these actions require significant time, effort, innovation, and investment to have meaningful impact. These include our digital transformation and facilities consolidation including consolidation of multiple fabs (which are part of our Enterprise Transformation Program) as well as our Asia Pacific Center of Excellence for materials, optics, and lasers where we are expanding our footprint to accommodate our long-term growth in the Philippines, Malaysia, Vietnam, and Singapore. We think the near-term cost of these actions will yield meaningful long-term return in the form of significant improvement in our cost structure and operating efficiency, which in turn we expect will benefit both our margin structure and our competitiveness and thereby our revenue growth and our profitability.

In addition, our diversification across product, technology, customer, and regional markets allows us to redeploy capital and people from low or declining returns to higher-return market opportunities. Almost by definition, the initial “investment” phase of such a shift typically entails lower gross margin, which eventually is followed by margin uplift as the investments and learning begin to translate into targeted yields, BOM costs and cycle times, enhanced operating efficiency, greater revenue volume, and increased overhead absorption.

Near-Term Focus on Execution; Increased FY24 Revenue Outlook Driven by Strong AI-Driven Datacom Demand. We have increased the lower end of our fiscal 2024 revenue guidance. We are now guiding for $4.62 – 4.70 billion versus our previous guidance of $4.55 – 4.7 billion. Underlying our revised outlook, the third quarter reinforced our confidence in the outlook for our Datacom vertical (which is within our Communications market) driven by AI-related datacenter builds by webscale, other cloud internet content providers (ICPs), and companies that supply them.

For the fourth quarter of fiscal 2024, we are forecasting 5% sequential revenue growth and almost 13% sequential non-GAAP EPS growth over the third quarter (at the midpoint of guidance). The expected revenue growth is driven primarily by the strength in our AI-related Datacom transceiver and silicon carbide businesses.

Improved Capital Structure and Ratings. On April 2, 2024, we successfully completed the repricing of our existing $2.4 billion secured Term Loan B. We will realize almost $9 million of annual interest savings from the repricing.

On February 21, 2024, Moody’s Investor Service upgraded the credit rating of Coherent Corp. to Ba2. Moody’s cited “The ratings upgrade reflects Moody’s expectation that Coherent’s financial metrics and cash generation will continue to improve. This reflects a recovery in end markets along with continued strong sales growth in optical transceivers serving generative artificial intelligence (GenAI) uses.”

VISIBILITY, KEY TRENDS, AND DEVELOPMENTS

Margin Structure: Opex Discipline Offsets Some Transitory Gross Margin Issues

As previously noted, strong operating leverage resulting from the revenue upside and better than expected operating expense control offset weaker than expected gross margin to drive operating margin just above the midpoint of our 14 – 16% third quarter guidance, which in turn contributed to our posting Non-GAAP EPS above the high end of our $0.32 – 0.52 guidance.

Our gross margin was adversely impacted by a number of issues that we have resolved or expect to resolve by mid-fiscal 2025. Collectively, these issues in the aggregate had an over 100 bps adverse impact on our Non-GAAP gross margin in the third quarter.

Lower than planned yields for some of our Datacom transceivers accounted for well over 50% of the third quarter aggregate impact. We have implemented corrective actions, and have already started to see improvement, and we expect to achieve our targeted level.

We also suffered from very low gross margin in our silicon carbide business due to a power failure at a crystal growth facility, which also resulted in an overhead absorption issue due to the significant adverse impact on our Silicon Carbide LLC revenue in the third quarter. We have addressed the power failure issue, and our silicon carbide revenue has returned to a positive trajectory.

Third Quarter of Fiscal 2024. Non-GAAP gross margin of 35.8% was below our 36 – 38% guidance and relatively flat with the 36.0% we reported in the second quarter of fiscal 2024. Non-GAAP operating margin of 15.1% was in-line with our 14 – 16% guidance and essentially flat with the 15.2% we reported in the preceding quarter. As previously noted, a number of transitory issues offset the strong sequential revenue growth to drive our disappointing gross margin. The strong sequential increase in revenue together with positive operating leverage offset the relatively weak gross margin to drive operating margin in-line with our guidance.

Fourth Quarter of Fiscal 2024. We expect to drive to 36.0 – 37.5% Non-GAAP gross margin and 16 – 17% Non-GAAP operating margin in our fourth quarter of fiscal 2024. The primary drivers of the expected sequential increase are greater revenue and improved operational efficiencies.

Fiscal 2024. We expect 35.7 – 36.3% Non-GAAP gross margin and 14.7 – 15.2% Non-GAAP operating margin for all of fiscal 2024 compared to our previous guidance of 36 – 38% and 14 – 16%, respectively.

Longer-Term. Our longer-term outlook for return to 40% Non-GAAP gross margin and 20% Non-GAAP operating margin remains unchanged.

Key Drivers. Underlying our longer-term view, unchanged from the preceding quarter, key drivers of operational excellence to attain each of the above targets are broadly focused on pricing, procurement, and productivity, and include:

1. Gross Margin:

◾ continuous rationalization and refreshing of the portfolio;

◾ continuous rationalization of the supply base for cost and resiliency;

9

◾ implementation of a streamlined Asia Pacific manufacturing Center of Excellence;

◾ moving up the value chain;

◾ operating cost reductions based on a more resilient and lower-cost manufacturing footprint;

◾ increased capacity utilization;

◾ favorable product mix, driven by product introductions with higher margins;

◾ productivity improvements through improvements in yields and quality;

◾ implementation of digital transformation and adoption of AI technology to improve efficiency in R&D, manufacturing, and G&A; and

◾ leveraging our service organization into new markets.

2. Operating Margin: in addition to the above drivers of gross margin improvement, we expect to drive future operating margin improvement from operating leverage by both increasing revenue and ongoing operating expense control, with the latter enhanced by the execution of:

◾ our Enterprise Transformation Program;

◾ our Synergy and Site Consolidation Plan;

◾ our Restructuring Plan; and

◾ additional cost and expense reductions underway.

Strategic Opportunities. As previously noted, as we transform the Company to improve operating performance, restructure our production footprint to enhance operating resiliency, and complete the integration of legacy Coherent, Inc., we are exploring other strategic opportunities—not including material acquisitions—to unlock shareholder value.

Enterprise Transformation Program. We have implemented and continue to make significant progress on our Enterprise Transformation Program. This program encompasses rollout of a new operating model, end-to-end global process capabilities and systems, and includes digital transformation, site consolidation, and restructuring. We expect this program, following full implementation, to drive significant operating efficiencies. We have completed the design of the program’s integrated business planning and management capability and are rolling it out in our business units. This capability will allow us to scale our business operations, improve inter-business unit coordination given our vertically integrated structure, and unlock significant value through better inventory management, reduced cost of goods sold (COGS), and improved long-range capacity and business planning.

In addition, as part of this program, our digital transformation is focused on designing and implementing a new integrated digital platform throughout the Company. Implementation will start in fiscal 2025 and extend through fiscal 2027 – 2028. We expect this digital transformation to drive improved ways of working, collaboration, and standardization of processes that should allow us to effectively scale our business while significantly reducing internal complexity.

Synergy and Site Consolidation. The stated goal of our Synergy and Site Consolidation Plan for the Coherent, Inc., acquisition was to achieve $250 million in annual synergies over three years, with $250 million of costs to achieve these synergies. We have accelerated some of the actions planned as part of our post-three-year synergy and site consolidation and relocation efforts. These relocations and other actions are expected to help offset our lower than expected supply chain cost savings that result from lower revenue and allow us to achieve our targeted $250 million in annual synergies. At the end of the first year, we reached $73 million of synergies for fiscal 2023. In the first nine months of fiscal 2024, we achieved another $131 million in synergies, an annualized run-rate of $175 million. To date, synergies are split 60% cost of sales and 40% operating expenses.

10

Restructuring. In the fourth quarter of fiscal 2023, we implemented a Restructuring Plan that includes site consolidations and closures as well as the relocation and requalification of certain manufacturing facilities. The following restructuring actions are intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient, and sustainable footprint and business model:

◾ China and Rest of Asia Site Consolidation. Consolidation of sites in China and the rest of Asia, including the closure of certain manufacturing facilities and sales offices and the establishment of new regional design centers closer to our customers in the Global South as part of a multi-year plan, are underway. The intent of these actions is to optimize our footprint in Asia. In addition, through these actions, we will replicate the state-of-the-art manufacturing lines we have in China to other parts of Asia to increase resiliency to our supply chain by taking advantage of the best practices of operational excellence, new product introductions, a smarter and shorter supply chain, and redundancy for sustainability.

◾ Compound Semiconductor Site Consolidation. Consolidation of compound semiconductor wafer fab and device manufacturing facilities, including the closure of half of these facilities, is a multi-year and cross-cutting initiative. We will consolidate into our most modern facilities with a stable baseline of operational excellence and will drive better utilization of our assets while reducing our costs and improving our new product introduction and technology innovation cycle times.

◾ Savings. We expect total savings for fiscal 2023 – 2025 to be $200 – 250 million, with annual savings of $110 – 140 million by fiscal 2025. We forecast savings associated with the Plan to be approximately $90 – 100 million for full fiscal year 2024.

◾ Costs to Achieve. We expect total costs to achieve these savings over the fiscal 2023 – 2025 period to be $175 – 200 million, including severance, retention, facility moves, accelerated depreciation, short-term duplicate costs, lease termination costs, and IT consolidation costs. In the third quarter of fiscal 2024, we recorded restructuring charges of $12 million, consisting primarily of employment termination costs and charges for accelerated depreciation and equipment write-offs.

◾ Restructuring Charges. We expect restructuring charges to be in the $25 – 35 million range for full fiscal year 2024 mainly comprised of employment termination, facility move costs, and accelerated. We expect restructuring charges to be in the $35 – 45 million range for full fiscal year 2025, consisting primarily of employment termination, facility move costs, and accelerated depreciation, and savings associated with the Plan to be $110 – 140 million for full fiscal year 2025. In fiscal 2023, restructuring charges were $119 million, primarily for workforce reduction and the write-off of property and equipment, net of $65 million from reimbursement arrangements.

11

Visibility

Backlog and Orders

In the third quarter, both orders and backlog decreased sequentially but increased year-over-year. The sequential decreases were consistent with our previous expectations. They primarily reflect ongoing normalization of order levels in our Networking segment, which in turn is being driven by ongoing moderation from the extraordinarily strong levels we have enjoyed for our 800G Datacom transceivers early in the still-young trend of AI-related datacenter builds.

◾ Backlog. We ended the quarter with approximately $2.74 billion of backlog, an approximate $150 million sequential decline from approximately $2.9 billion at the end of the preceding quarter and a well over $100 million increase from the year-ago quarter.

◾ Orders. Orders decreased sequentially by approximately 4% but increased year-over-year by approximately 11%. The sequential decline was primarily driven by decreased orders in our Networking segment due to continued decreases in lead times. We also saw a second straight quarter of double-digit order growth in our Lasers segment. The year-over-year increase was primarily driven by strong year-over-year order growth in our Networking and Lasers segments, which offset a large year-over-year decline in orders in our Materials segment. The year-over-year Materials orders decline primarily was driven by a product design change by our largest customer within our Consumer Electronics vertical (which we have highlighted in each of the past four quarters), along with macroeconomic uncertainty.

Networking Segment: Ongoing AI Datacom Strength; Disappointing Telecom

We continue to enjoy strong momentum in our Networking segment driven by 800G transceivers for AI. Recovery in our Telecom business, however, is slower than we expected.

Near-Term. Near-term, Datacom transceiver order strength offset ongoing weakness in our Telecom business to drive an over 25% year-over-year increase in overall orders for our Networking segment. Networking orders decreased by approximately 15% sequentially primarily reflecting a contraction in customer order lead times since the initial surge in AI-related 800G orders at the end of the fourth quarter of fiscal 2023. As our 800G Datacom transceiver shipments continue to ramp against our significant backlog and as lead times shorten, we expect our backlog to continue to decline.

In terms of revenue, our Networking segment enjoyed strong sequential and year-over-year growth and a record quarter driven by record Datacom transceiver revenue. Networking revenue increased sequentially by $95 million, or 18%, and year-over-year by almost $68 million, or 12%, to $619 million. We expect ongoing strong AI-related Datacom transceiver revenue growth to drive another quarter of strong sequential revenue growth in our Networking segment in our fourth quarter of fiscal 2024.

12

Longer-Term. Our unchanged outlook for strong longer-term Networking revenue growth is based on ongoing strength in our AI-related Datacom business along with recovery in our non- 800G Datacom and our Telecom businesses. Underlying our longer-term view are strong AI Datacom market trends; expanding AI-related customer engagements; our next-generation AI Datacom products including, in the near-term, 1.6T and, in the longer-term, 3.2T transceivers along with enabling active and passive components; ongoing inventory digestion that we expect will lead to order normalization in our non-800G Datacom and Telecom businesses by fiscal 2025; eventual improvement in Telecom end demand trends; and market penetration and revenue ramp of new Telecom products including our DCO transceivers and subsystems products.

Datacom Vertical

AI-Related Datacom Transceivers: Ongoing Strong Demand. Another quarter of strong orders and the further expansion of our customer engagements during the quarter reinforced our confidence in strong near- and longer-term demand for our AI-related Datacom transceivers. Our total Datacom transceiver revenue increased by well over $100 million, or well over 30%, sequentially and by well over $100 million, or almost 50%, year-over-year. We continue to expect AI-related revenue to account for more than 50% of our Datacom transceiver revenue for all of fiscal 2024 and to enjoy strong growth in fiscal 2025 and beyond. 800G comprises the bulk but not all of our AI-related Datacom transceiver revenue.

800G. Datacom strength was driven by a third straight quarter of strong AI/ML-related orders for our 800G Datacom transceivers from webscale, cloud ICPs, and other companies in the webscale and cloud ICP ecosystem. Speaking to ongoing strength in demand and strong ramp in production, our 800G Datacom transceiver revenue increased sequentially by almost 80% to almost $200 million in the third quarter, which followed over 100% sequential growth in the preceding quarter. We expect well over 30% sequential growth to $250 million for our fourth quarter of fiscal 2024.

1.6T on the Horizon. We also are excited by the active engagement we are seeing from key customers for 1.6T transceivers and components. In response to customer demand, we continue to make progress toward expected commercial launch and revenue in calendar 2025 and expect to ship commercial samples of 1.6T products to our customers starting in the first quarter of fiscal 2025 of our 1.6T transceivers including designs based on silicon photonics, 200G EMLs, and DFB-MZ lasers. We see the opportunity for, and expect, these 1.6T solutions to increase our share of the AI-related Datacom transceiver and component opportunity by relying on our broad and deep level of vertical integration relative to our direct transceiver competitors.

AI-Customer Diversification. While the revenue opportunity remains concentrated in a relatively limited number of potential customers within the AI-related Datacom transceiver market, four different customers are on track to generate meaningful AI-related Datacom revenue for our full year fiscal 2024.

Market-Leading Position. Our transceivers are designed to be compatible with all of the protocols and standards that are currently used for AI connectivity. We believe that we are equally well-positioned—in terms of technology, products, and customer relationships—to address anticipated evolutions of AI connectivity architectures. We believe our competitive advantages and strategic key customer engagements are due to the breadth of our solutions, our technology innovation, and our broad vertical integration, which improve our ability to ramp volume production and to offer the highest performance and most cost-competitive solutions to the market. The retooling of datacenter architectures and integration of AI clusters by webscale and other cloud companies represent an immediate and direct growth opportunity for our Datacom business—both our transceivers and our enabling active and passive components, especially leading-edge high-speed lasers.

13

Mix Heavily Weighted to Faster Growth, Higher Line Rate Transceivers. 800G Datacom transceiver revenue accounted for almost 50% and together with 200G and 400G Datacom transceivers accounted for almost 80% of our total Datacom transceiver revenue in the quarter.

AI Transceiver Ramp Progression

As expected, we realized meaningful improvements in both our supply chain constraints and our ability to ramp production in the third quarter. Our external supply chain shortages had less than a $10M adverse revenue impact in the quarter. All of the shortages impacted our Datacom transceivers business. We expect an immaterial level of supply constraints going forward assuming, as always, no large spikes in customer demand or product design/configuration changes.

Telecom: Disappointing Near-Term; Unchanged Strong Longer-Term Outlook

Recovery in our Telecom vertical is proving slower than we had previously projected. Our Telecom revenue sequentially decreased in the third quarter and fell short of our internal forecast, albeit modestly on both counts, and we expect relatively flat revenue growth in our current fourth quarter. The primary issue is soft end demand as communication service providers (CSPs), webscale, and other ICP customers continue to delay projects and reduce or keep a tight rein on their capital expenditures.

Now Expect Start of Recovery in FY25. While there remains some uncertainty regarding the timing of market recovery, we expect improvement in our Telecom revenue in fiscal 2025. Underlying our view, we see a number of drivers including ongoing rebound in Telecom revenue from China driven by 400G C+L-band network upgrades, increasing revenue contribution from our new transceivers targeted to the ZR and ZR+ coherent transceiver market opportunity, and share gains in certain key Telecom product segments.

Unchanged Longer-Term Outlook. Unchanged from the preceding quarter, longer-term, we expect to benefit from ongoing market recovery; strong customer traction for several new products that expand our addressable market; new market opportunities with a number of new, industry-leading products; and a variety of key emerging opportunities at new prospective direct customers. We are especially excited about the number and quality of customer design win opportunities for our new 100G ZR and high-power 400G ZR/ZR+ pluggable transceivers at CSPs, webscale companies, and large NEMs. The 100G ZR transceivers are based on our own internally developed Steelerton DSP, which represents a disruptive product in our portfolio. We currently are qualified and shipping our 400G ZR/ZR+ transceivers, and we expect to commence ramping production and commercial shipments of our new 100G ZR transceivers in the fourth quarter of fiscal 2024.

14

Lasers Segment: Sustained Improvement

In our Lasers segment, while the macroeconomic environment continues to impact demand, we saw additional signs of improvement in the quarter and continue to expect to see further improvement in the fourth quarter of fiscal 2024 and beyond. Orders in our Lasers segment increased by over 7% sequentially and 17% year-over-year, and marked the highest level since our second quarter of fiscal 2023. Lasers segment revenue was essentially unchanged from the preceding quarter but declined (by less than 5%) from the year-ago quarter. While having modestly declined on a sequential basis, our Display service revenue increased by almost 30% from the year-ago quarter primarily driven by the ongoing increase in OLED fab utilization and depletion of service spare parts inventory.

Underlying our expectation for further Lasers improvement in the fourth quarter of fiscal 2024 and throughout fiscal 2025 and beyond, the sequential and year-over-year order strength in the quarter reflects a number of key positive trends in our Display Capital Equipment and Semiconductor Capital Equipment verticals within our Industrial market. While macroeconomic uncertainty continues to restrain current demand trends both in our Precision Manufacturing vertical within our Industrial market and in our Instrumentation market, we also expect favorable underlying trends in each of these to eventually contribute to meaningful incremental improvement in our Lasers segment operating performance.

The key driver of demand for our Display Capital Equipment revenue is capacity expansion in existing OLED fabs as well as the buildout of new Gen 8 OLED fabs. OLED growth is being driven by further adoption of OLED into smartphones, increasing OLED adoption into tablet and laptop computers, and a rebound in smartphone sales volumes from the lowest levels in a decade.

We expect our excimer laser revenue in our Semiconductor Capital Equipment vertical to further strengthen in fiscal 2025.

We expect our Lasers segment also to benefit from ongoing penetration of the welding market opportunity with our ARM (Adjustable Ring Mode) laser system particularly as it relates to battery welding. We are enjoying increasing market breadth and depth of customer adoption, which we expect to drive a corresponding ongoing strong ramp in revenue generation.

As discussed at greater length below, we remain excited as to our longer-term outlook for both our Industrial and Instrumentation markets.

Materials Segment: Enabling the 800G AI Ramp and Executing Multi-Year Fab Consolidation

While our Materials segment remains challenged, we saw a 7% sequential increase in orders in the quarter and expect additional improvement in our current fourth quarter followed by more meaningful improvement throughout fiscal 2025. The sequential increase in orders marked the first quarter of improvement following a six-quarter downtrend including an over 20% sequential decline in the preceding quarter. The sequential order increase in the quarter was primarily driven by strong demand for AI-related Datacom VCSELs. The increase also reflects the winding down of the previously disclosed significant reduction in demand in our Consumer Electronics business driven by a design change by our largest Consumer Electronics customer. A key driver of our Materials segment revenue outlook for this initial rebound to extend into and strengthen in fiscal 2025 is the demand for lasers for our internal Datacom transceiver ramp, combined with the substantial increase in demand from other transceiver manufacturers; this is requiring a substantial increase in investment and a strong focus on product development and NPI ramps in our wafer fabs as we invest to expand capacity to support not only 800G and 1.6T for the next few years, but also the development of 3.2T technologies.

15

As part of our Synergies and Site Consolidation Plan, we have initiated consolidation of certain wafer fabs to increase utilization and thereby profitability.

Silicon Carbide: Near-Term Challenges

We continue to be excited for the long-term growth outlook for our silicon carbide business based on what we expect to be robust silicon carbide end demand and our strong competitive position. As we expected, however, the previously noted power failure adversely impacted our Silicon Carbide LLC revenue in the quarter. This issue also adversely impacted our third quarter gross margin for this business. We are making progress working through the issue and expect a greater than 50% increase in our Silicon Carbide LLC revenue, which should also drive sequential improvement in our silicon carbide gross margin. We have moderated our fiscal 2025 silicon carbide revenue growth outlook to take into account the industrywide slowdown in EV demand and production.

As a reminder, during the second quarter of fiscal 2024, we consummated the previously announced transactions (the “Transactions”) with Mitsubishi Electric and DENSO Corporation pursuant to which those entities invested an aggregate of $1 billion in exchange for noncontrolling ownership interests of 12.5% each in Silicon Carbide LLC, a newly formed LLC into which we contributed our silicon carbide business, and entered into long-term supply agreements that will support their demand for silicon carbide substrates and epitaxial wafers.

The operating results of Silicon Carbide LLC are consolidated in our income statement with Mitsubishi Electric’s and DENSO’s noncontrolling interests in Silicon Carbide LLC reported as “Net Loss Attributable to Noncontrolling Interests” below the Net Loss line on our income statement. The aggregate $1 billion of cash we received is reported as “Restricted Cash (current and noncurrent)” on our balance sheet.

Capital Expenditure and Debt Reduction Outlook

We are tightening our capital expenditure outlook for fiscal 2024 to $365 – 385 million, with our Silicon Carbide LLC funding approximately $150 million of this amount. In the third quarter of fiscal 2024, our total capital expenditure was $93 million, of which $52 million was funded by Silicon Carbide LLC. We expect capital expenditures of $115 – 135 million for the current fourth quarter with Silicon Carbide LLC funding approximately $50 million of this amount.

We now expect aggregate debt repayment between $225 – 250 million for all of fiscal 2024 compared to our previous expectation of $225 – 275 million from the preceding quarter. This outlook compares to approximately $200 million prior to our closing of the Silicon Carbide Transactions.

As a reminder, the Transactions are expected to allow Coherent to increase its available free cash flow to provide greater financial and operational flexibility to execute its capital allocation priorities including debt reduction. And as we have noted on previous occasions, the Transactions relieve the need for Coherent to fund future operating or capital expenditures of Silicon Carbide LLC.

16

Trade Compliance Update on U.S. Restrictions: New Semiconductor-Related Export Controls – No Meaningful Impact Expected

Unchanged from the preceding quarter, at present, we do not expect a meaningful adverse impact from the new round of export control restrictions announced by the U.S. Department of Commerce on October 17, 2023. These newest restrictions target exports of certain integrated circuits and semiconductor manufacturing equipment to China and impose new end use and end user controls to constrain certain technology development in China. As with others in the industry, we continue to assess these new rules and to update our compliance controls and actions to account for them.

17

PART II—FINANCIAL OVERVIEW

THIRD QUARTER FISCAL

Revenue. We generated $1.209 billion in revenue, above our $1.020 – $1.200 billion guidance range and a 7% sequential increase but a 3% year-over-year decrease. Strong Networking segment revenue drove both the upside and the sequential growth. On a year-over-year basis, a significant decrease in Materials revenue and modest decrease in Lasers revenue more than offset strong growth in Networking revenue to drive the overall revenue decline. Our revenue growth continues to be impacted by soft end market demand due to the uncertain macroeconomic environment, inventory digestion in certain end markets including, most prominently, non-AI Datacom and Telecom, and a design change by a prominent customer in our Consumer Electronics vertical.

◾ Materials. Revenue of $239 million for our Materials segment decreased by approximately 6% sequentially and by approximately 26% year-over-year but was only slightly below our internal forecast. The sequential and year-over-year decreases were primarily driven by sequential and year-over-year decreases in our Consumer Electronics revenue, as we had expected, along with the production ramp issue that adversely impacted our Silicon Carbide LLC revenue in our Automotive vertical.

◾ Networking. Revenue of $619 million for our Networking segment healthily exceeded our internal forecast, increased by approximately 18% sequentially and by approximately 12% year-over-year, and marked a quarterly record. The sequential increase was primarily driven by the almost 80% sequential increase in our AI-related 800G Datacom transceiver revenue to almost $200 million for the quarter, which was partially offset by a sequential decrease in our Telecom revenue and ongoing weakness in our non-800G Datacom business. The year-over-year increase was primarily driven by the year-over-year increase in our AI-related Datacom revenue partially offset by significant year-over-year revenue decreases for both our Telecom and non-800G Datacom businesses, both of which are primarily due to customer inventory digestion along with some project delays by customers in our Telecom vertical.

◾ Lasers. Revenue of $351 million for our Lasers segment was essentially flat compared to the preceding quarter, and a 4% decrease compared to the year-ago quarter. The slight sequential decrease was driven by our Industrial market. The year-over-year decrease was primarily driven by macroeconomic uncertainty. As we observed in the preceding quarter, encouragingly, we are starting to see improvement in our Laser service revenue, primarily driven by increasing fab utilization and depleted inventory in our Display Capital Equipment market segment, which in turn is driven by further OLED adoption in smartphones and the inception of OLED adoption in laptop computers and tablets.

Non-GAAP EPS. Non-GAAP diluted earnings per share was $0.53, above the high end of our $0.32 – 0.52 guidance range and up from $0.36 in the preceding quarter driven by the revenue upside partially offset by lower than expected gross margin.

Non-GAAP Gross Margin. 35.8%, which was below our 36 – 38% guidance range and a 20 bps sequential decrease and over 150 bps year-over-year decrease. The primary drivers of the

18

sequential decrease were higher than expected COGS, which more than offset the sequential revenue increase. The primary drivers of the year-over-year decline were lower revenue, which resulted in lower fixed cost absorption and higher than expected COGS, including lower yields in the datacom vertical and higher inventory provisions.

Non-GAAP Operating Expenses. $250 million or 20.7% of revenue, which is below the midpoint of our $246 – 262 million guidance but represents a sequential increase of $14 million and a year-over-year increase of $4 million. Operating expenses as a percentage of revenue decreased by 15 bps sequentially but increased by 87 bps year-over-year. The primary driver of the sequential decrease was strong revenue growth partially offset by higher IR&D expenses. The primary driver of the year-over-year increase was the rate of decrease in revenue combined with a slight increase in operating expenses.

Non-GAAP Operating Margin. 15.1%, which is just above the midpoint of our 14 – 16% guidance and is a sequential decrease of 10 bps and a year-over-year decrease of 240 bps. The relatively flat sequential performance was driven by higher operating leverage from higher revenue and solid operating expense discipline which offset slightly lower gross margin compared to the preceding quarter. The year-over-year decrease was primarily due to the year-over-year decrease in gross margin and to slightly higher operating expenses.

Operating Cash Flow. $117 million, compared to $152 million in the year-ago quarter and $67 million in the preceding quarter.

Capital Expenditures. $93 million, $52 million of which was funded by our silicon carbide business. As previously noted, we have tightened our capital expenditure outlook for fiscal 2024 to $365 – 385 million and we continue to expect the Silicon Carbide LLC to fund approximately $150 million of this amount.

Debt Reduction. In the quarter, we paid down $58 million of our outstanding debt.

Debt. Gross debt was approximately $4.2 billion and net debt was approximately $3.3 billion at the end of the quarter, compared to $4.3 billion and $3.4 billion, respectively, at the end of the preceding quarter.

Leverage. Gross leverage was 4.4x and net leverage was 3.5x at the end of the quarter on a calculated basis, using the trailing 12 months of adjusted EBITDA at March 31, 2024, unchanged from the preceding quarter. Including the cost savings and synergy credit of $326 million allowed in the credit facility, gross leverage was 3.3x and net leverage was 2.6x at the end of the quarter compared to 3.2x and 2.5x, respectively, at the end of the preceding quarter. The Company’s credit agreement allows for customary add backs to Adjusted Consolidated EBITDA including cost savings, operating expense reductions, and synergies in connection with any restructuring, cost-saving initiative, or other initiatives.

◾ Target: Our long-term leverage target remains 2.5x synergized gross leverage.

PART III—NEAR & LONG-TERM TRENDS BY MARKETS & REGIONS

MARKETS

We report in four major end markets, which comprise ten verticals to provide transparency to investors.

INDUSTRIAL

Revenue. Third quarter revenue of $421 million for our Industrial market was flat sequentially but decreased by 4% year-over-year. The flat sequential revenue was driven by revenue decline in our Aerospace & Defense vertical offset by modest revenue growth in our Semiconductor Capital Equipment vertical while our Display Capital Equipment and Precision Manufacturing verticals were essentially flat. The modest year-over-year revenue decline in our Industrial revenue was driven by decreases in our Semiconductor Capital Equipment (specifically driven by reduced revenue for products used in EUV applications) and Precision Manufacturing verticals partially offset by year-over-year revenue growth in our Display Capital Equipment and Aerospace & Defense verticals.

Industrial Market Overview Webcast. As part of our ongoing effort to increase transparency and enhance the understanding of our investors, we discussed our Industrial market in greater detail on our December 14, 2023, Industrial Market Overview webcast. A replay and investor presentation are available on our website at coherent.com/company/investor-relations/financial-webcasts.

Demand Trends. While the near-term outlook for our Industrial business remains challenged by the macroeconomic backdrop, we enjoyed another quarter of improving demand trends in the third quarter, expect additional improvement in the fourth quarter of fiscal 2024 and expect even greater improvement in fiscal 2025, and are excited by a number of longer-term trends. Near-term, we are encouraged by a strong order trend in our Industrial market. The third quarter marked another quarter of double-digit sequential order growth, and we expect this trend to extend into our current fiscal fourth quarter. We are seeing an especially strong demand trend for our excimer lasers and related service revenue, which in turn are being driven by strong demand in our Display Capital Equipment vertical. The third quarter marked a third straight quarter of exceptionally strong double-digit order growth for our Display vertical. Following strong sequential growth in the preceding fiscal second quarter, our Semicap orders were relatively flat in the third quarter, and we expect them to remain relatively unchanged in our current fourth quarter. While orders in our Precision Manufacturing vertical slightly declined from the preceding quarter, we expect strong double-digit sequential improvement in our current fourth quarter.

A more in-depth discussion of trends within each of our Industrial verticals follows.

1. Semiconductor Capital Equipment Vertical: Beyond the near-term growth we expect for our Semicap vertical, we see favorable long-term demand trends for our Semicap business. We expect these trends to drive strong double-digit annual revenue growth in our Semicap vertical.

◾ Revenue. Revenue in our Semicap vertical increased by 4% sequentially but decreased by 4% compared to a year-ago record quarter. As discussed at greater length below, the sequential increase was driven by an initial rebound in back-end applications of this vertical while revenue for front-end applications was relatively flat.

21

◾ Market Overview. As previously noted, over the long term, we expect strong annual revenue growth in our Semicap vertical. Since fiscal 2020 we have driven record revenue every year in this vertical driven by the increased use of lasers, materials, and optics in advanced semicap tools. Near-term, we expect to see relatively flat revenue in our current fourth quarter followed by improved revenue growth throughout fiscal 2025 with the benefit of the start of recovery in the semiconductor market following the current cyclical downturn. We have started to see recovery in the back-end assembly and packaging equipment segment of our Semicap vertical. Key Semicap end market drivers include increased demand for leading-edge chips for AI, high-performance computing, and automotive. We also see favorable long-term demand trends for our Semicap business augmented by government policy-driven fab investments (i.e., government subsidies for expanding production capacity) and, most importantly, our increasing serviceable addressable market (SAM) driven by portfolio expansion and the increased adoption of high-performance lasers, over the longer term. We enjoy a strong NRE-funded design-win pipeline from existing and new customers across both front-end wafer processing and wafer inspection, among new applications.

◾ Front-End. We enjoy a particularly strong competitive position in front-end Semicap, which accounts for most of our Semicap vertical revenue. We have a number of new programs and design wins on track to drive future incremental revenue. Our semiconductor wafer inspection backlog remains strong. Our front-end laser business posted another quarter of solid sequential growth driven by a record quarter for laser shipments into wafer inspection. This growth was partially offset by ongoing softness in our EUV business.

◾ EUV Rebound. Consistent with public statements by our end customer, we expect to see EUV inventory normalization starting in our current fourth quarter of fiscal 2024 and expect to enjoy a rebound in EUV demand in fiscal 2025 as our end customer ramps up shipments of its EUV systems. Dozens of our solutions spanning our Materials and Lasers segments are designed into these EUV systems.

◾ Back-End Rebound. As previously noted, we also expect to benefit from recovery in the back-end assembly and packaging segment of our Semiconductor Capital Equipment vertical. After a prolonged period of softness, the back-end segment has started to benefit from improved demand in China driven by increases in China domestic smartphone sales. In the third quarter, we enjoyed double-digit back-end Semicap revenue growth on both a sequential and year-over-year basis. We expect ongoing back-end revenue growth in our current fourth quarter of fiscal 2024 and throughout our fiscal 2025. The key drivers of our back-end growth outlook are AI, high-performance computing, and 5G. Notably, advanced packaging is driven by demand for AI chips, which also creates new potential opportunities for our lasers and advanced materials in the Semicap vertical.

◾ Additional Growth Opportunities. We are excited by significant growth opportunities in the Semicap vertical for our advanced composite materials and diamond. We launched our new picosecond industrial green laser HyperRapid NXT-Green at 100W at Photonics West (January 2024) to meet the market demand for higher process quality and throughput. We also expect incremental revenue contribution from wins with new advanced ceramic materials and assemblies for next-generation lithography machines.

22

◾ AI. Our opportunities should be favorably impacted by AI. The widespread adoption of AI will drive significant demand for leading-edge semiconductor technologies, including next-generation node logic chips, high bandwidth memory (HBM), and advanced packaging. We expect this trend to drive incremental demand for our lasers and advanced materials, which are essential components of key enabling Semicap tools.

2. Display Capital Equipment Vertical: We see favorable near- and long-term demand trends for our Display vertical. We expect strong sequential revenue growth in our current fourth quarter and throughout our fiscal 2025.

◾ Revenue. For the quarter, revenue in our Display Capital Equipment vertical was flat on a sequential basis but increased by 4% year-over-year.

◾ Market Overview. The quarter reinforced our confidence as to an emerging multi-year Display upgrade cycle with a recovery being underway that we expect to lead to sequential revenue growth in the fourth quarter of fiscal 2024 with further improvement in fiscal 2025 and beyond for our Display business. The third quarter marked a second straight quarter of exceptionally strong double-digit order growth in our Display vertical. Key drivers of this improving demand include further OLED adoption in smartphones and accelerating OLED adoption in laptop computers and tablets, and both increasing investments in Gen 6 fabs and announcements of construction of Gen 8 OLED fabs to address this expanding IT market opportunity and, in the case of service revenue, increased fab utilization and reduced inventories of Display service spare parts.

◾ Excimer Laser Annealing Demand. As previously noted, this strengthening demand is showing up in increasing demand for our excimer lasers. During the third quarter, we enjoyed a significant increase in orders for our excimer laser annealing systems for capacity expansions in several Gen 6 OLED fabs in China. The quarter also marked the highest order level for new excimer systems in the past two years. We expect incremental strength from the buildout of Gen 8 OLED fabs, with the first Gen 8 groundbreaking in our preceding fiscal second quarter.

◾ Competitive Position. We continue to be the leading supplier to virtually all of the leading companies in the Display vertical, and we enjoy a broad technology platform to address virtually all Display companies’ future roadmaps. Excimer laser annealing continues to account for the largest portion of our Display SAM.

◾ OLED. The long-term outlook for our Display excimer laser annealing business remains robust. We expect meaningful incremental revenue growth in our Display vertical driven by further OLED adoption in smartphones and by investments in new Gen 8 OLED fabs for capacity expansion for larger substrates for laptop computers and tablets and by OLED adoption in the automotive market. The move to larger OLED formats and new OLED display types will require new excimer laser annealing systems along with new lasers for cutting for new Gen 8 fabs. We are well positioned for both cutting and larger-format annealing. We expect the IT display market to increase from approximately $6 billion in calendar 2023 to almost $14 billion in calendar 2026 with OLED displays growing by well over 100% from approximately $3 billion to approximately $8 billion.

◾ China. China’s OLED sector has witnessed a significant uptick since the second half of calendar 2023. Anticipated bookings from Chinese customers via equipment integrators are expected to surpass $100 million in calendar 2024. During the third quarter, we received multiple orders for capacity expansion for Gen 6 fabs in China. In addition, several Chinese display manufacturers are poised to invest in new Gen 8 OLED fabs to capitalize on the growing demand for OLED IT panels.

23

◾ New DPSS Laser: No Adverse Display Services Revenue Impact. We expect our new PYTHON DPSS laser and the associated line-beam system to enhance our leading position in the OLED annealing market for larger IT displays. Successful annealing tests with various display customers have been performed and are still scheduled for the coming months. We do not expect PYTHON deployments to result in customers decommissioning any of our existing deployed excimer laser systems. Accordingly, we do not expect ramp of PYTHON deployments to adversely impact our Display service revenue; rather, we expect PYTHON to augment our service revenue given that each PYTHON system will generate service revenue with a compelling cost of ownership for our customers.

◾ MicroLED. Long-term Display Capital Equipment demand is also augmented by the emergence of the microLED market and the adoption of laser lift-off and mass transfer processes. We received several additional orders from our OEM customers for both laser lift-off and laser mass transfer equipment for end customers in China, Taiwan, and Korea. The publicly announced decision by a leading consumer smartwatch company to withdraw its microLED smartwatch project does not impact our assessment of the market opportunity. Smartwatches have never been a focus area for our microLED display plans; rather, we remain focused on the large-format display opportunity for microLED.

◾ Service. Although still slightly below the level of two years ago, our Display service revenue increased by almost 30% compared to the same quarter a year ago. While smartphone sales remain near the lowest level in a decade, several OLED fabs in Korea and China are seeing increased fab utilization, which combined with depleted inventory of service spare parts has driven a meaningful sequential increase in our service business. We expect both increasing fab utilization and new excimer system laser installations to drive further longer-term recovery in our Laser service revenue.

3. Precision Manufacturing Vertical: While macroeconomic uncertainty continues to present a challenge for our Precision Manufacturing vertical, we continue to see a strong long-term outlook for this market driven by new product offerings that enhance our SAM and competitive position. An eventual macroeconomic rebound will especially affect Precision Manufacturing demand, our most macro-impacted vertical in the Industrial market.

◾ Market Overview: Overall market conditions in Precision Manufacturing have stabilized but remain well off previous levels in-line with the Purchasing Manager’s Index (PMI), a key market indicator for this vertical. Regionally, both China and North America are showing some signs of recovery. However, Europe remains soft with an unclear outlook. We expect overall market improvement starting in fiscal 2025. Independent of, or over and above, recovery in market demand, we see a number of opportunities to drive significant incremental revenue growth in this market vertical. These include ongoing customer penetration and revenue ramp for our ARM laser and line-beam forming system in the welding market, especially for EV batteries; re-entry into the fiber laser cutting market with what we believe to be a best-in-class performance and lowest-cost platform; and ongoing success in the medical device manufacturing market.

24

◾ Revenue. Third quarter revenue for our Precision Manufacturing vertical was relatively unchanged from the preceding quarter but declined by 11% year-over-year.

◾ Electric Vehicles and EV Battery Assembly: Our key target market of Electric Vehicles (EVs) continues to provide a healthy long-term market growth outlook of over 15% notwithstanding the recent industry pullback. We are especially excited by our expanding breadth and depth of customer penetration in EV battery welding—and the revenue growth potential attending the pace of our cost reductions and performance improvements in our new ARM laser and beam delivery systems.

◾ Increasing Breadth and Depth of ARM Adoption. Our differentiated ARM laser and beam delivery systems are enjoying increasing breadth and depth of customer penetration. Exceptionally strong ARM performance and results for EV battery welding are opening up new customer and market opportunities. We have now gained entrée for ARM into virtually every major EV battery maker. We also have seen the inception of existing ARM customers leveraging our ARM laser systems in more conventional automotive welding applications.

◾ Fiber Laser Cutting. We are excited by the long-term revenue opportunity enabled by our re-entry into the fiber laser cutting market, leveraging the substantial level of vertical integration and breadth of technology differentiation resulting from the acquisition of Coherent, Inc. Taking advantage of our new fiber laser platform, our complete vertically integrated in-feed of components including pump diodes, and our Chinese production footprint, we believe we will have the highest-performance and lowest-cost platform for this market.

◾ Fiber Laser Component Demand In China. We are seeing a welcome uptick in demand for our fiber laser component business in China driven by improving demand for fiber lasers both in China and for export abroad by Chinese customers. Our current generation of single-emitter diodes has seen good growth in demand along with our high-performance active and passive fiber products. We continue to engage with customers regarding our new, very high-power chips.

COMMUNICATIONS

Revenue. For the quarter, Communications revenue increased by 18% sequentially and by 14% year-over-year to $616 million. The sequential increase was primarily driven by the ongoing ramp in our AI-related 800G Datacom transceiver revenue. Our non-800G Datacom revenue continues to be impacted by inventory digestion and a shift in capex priorities toward AI by webscale customers. Our Telecom revenue continues to be impacted by inventory digestion along with delays in projects and capital expenditures by certain CSPs.

Datacom/Telecom. Datacom revenue increased by almost 30% sequentially and by almost 60% year-over-year to $463 million or approximately 75% of our total Communications market revenue. Telecom revenue decreased by 6% sequentially and by 38% year-over-year to $153 million or 25% of our total Communications market revenue.

Communications Market Overview Webcast. As part of our ongoing effort to increase transparency and enhance the understanding of our investors, we discussed our Communications market in greater detail on our September 19, 2023, Communications Market Overview webcast. A replay and investor presentation are available on our website at coherent.com/company/investor-relations/financial-webcasts.

Follow-Up Investor Briefing From OFC. We also hosted a follow-up in-depth discussion of our Communications market on March 26, 2024, at the OFC conference in San Diego. A replay and investor presentation are available on our website at coherent.com/company/investor-relations/financial-webcasts.

Long-Term Demand Trends. We continue to expect ongoing strong long-term growth in our Communications market driven by favorable secular trends in both our Datacom and Telecom businesses. Underlying our outlook:

1. Datacom Vertical. We continue to expect strong long-term Datacom revenue growth based on our backlog, order book, and strong customer engagements for AI-related datacenter buildouts. We currently project a 21% CAGR for all datacom transceivers from calendar 2023 to calendar 2028 largely driven by growth in 800G and 1.6T. Near-term, we expect another quarter of strong sequential Datacom revenue growth for the current fourth quarter of fiscal 2024 followed by strong year-over-year growth for all of fiscal 2025.

◾ AI/ML. A fourth straight quarter of strong demand for our Datacom transceivers for AI-based datacenter buildouts reinforced our excitement as to the impact on our Datacom business from the rapid growth of AI/ML, especially generative AI. We also are excited by the ongoing strong interest we are seeing from key customers for 1.6T transceivers along with 400G and 800G transceivers and components. Retooling of datacenter architectures and integration of AI clusters by webscale and other cloud ICP companies represent an immediate and direct growth opportunity for our Datacom business—both our transceivers and our enabling active and passive components, especially leading-edge high-speed lasers.

◾ Implications of Recent AI Product Announcement. The recent announcement about next-generation AI platforms from the market leader further reinforces our bullish view of the AI Datacom transceiver market. We note that in these new servers, the optical bandwidth per GPU has doubled along with a nine-fold increase in the number of GPUs. The front-end connectivity remains optical, and the back-end fabric remains electrical. We are also excited regarding the opportunity that some of the back-end fabric connectivity will present for optical penetration.

◾ More Than Just Datacom Transceivers. We see the longer-term benefit of AI/ML extending well beyond Datacom transceivers to impact other product markets that we address and also to enable significant operating efficiencies across our organization.

◾ Webscale. These orders also reflect our strong technology platforms and competitive position relative to webscale and cloud ICP AI/ML-driven datacenter deployments. For the quarter, webscale and large cloud ICP customers and customers that incorporate our transceivers in solutions sold to webscale and large cloud ICP customers accounted for virtually all of our AI-driven 800G and the bulk of our overall Datacom transceiver revenue. Webscale customers directly and indirectly accounted for over 75% of our total Datacom transceiver revenue for the quarter.

26

◾ Competitive Positioning. Our investments in high-speed lasers over multiple decades have placed us in a unique position to meaningfully participate in the AI connectivity market, including for the upcoming 200G per optical lane era, required for 1.6T and eventually 3.2T Datacom transceivers, with multiple leading-edge laser platforms including DFB-MZs, EMLs, VCSELs, and high-power lasers for silicon photonics. We also believe we benefit from having production footprint both outside of and within China, which allows us to address all customers’ preferences as to manufacturing locations. We are focused on winning by time to market, time to volume, and time to performance advantages.

◾ 1.6T. In response to customer demand, we continue to make progress toward expected commercial launch in calendar 2025 and expect to ship commercial samples starting in the first quarter of fiscal 2025 of our 1.6T transceivers and components. We expect to be strongly positioned for the 1.6T market opportunity with multiple 200G-ready in-house technologies to choose from including EMLs, DFB-MZs, silicon photonics, and eventually 200G VCSELs.

◾ 200G VCSELs. We have made great progress in overcoming technical hurdles toward commercializing our 200G VCSELs.

◾ OCS. At the 2024 Optical Fiber Communications (OFC) conference, we announced and demonstrated our DLX (Datacenter Lightwave Cross-Connect) optical circuit switch (OCS). DLX represents what we believe is a unique industry-leading solution that strongly positions us to address and capture a significant portion of what we expect to be a significant incremental market opportunity within the next five years. DLX is based on the highly reliable and field-proven digital liquid crystal technology that we currently use in our wavelength selective switch (WSS) products. We have recent engagements with several leading AI webscale companies. OCS deployment drives significantly enhanced operating efficiency and return on invested capital in AI architecture.

◾ Silicon Photonics. We have been shipping silicon photonics-based integrated coherent components and transceivers for many years. This year, to address a segment of the AI-driven Datacom transceiver demand, we launched our silicon photonics-based 800G-DR8 Datacom transceiver. This transceiver is ideal for use in machine learning and training networks that need a link reach longer than 100 meters or where our customers prefer a single-mode over a multimode fiber cabling infrastructure in shorter reaches. As with all silicon photonics-based transceivers, an InP high-power continuous wave (CW) laser is needed to generate the light, and we are developing silicon photonics and InP high-power CW lasers to support our silicon photonics-based transceivers.

◾ Linear Pluggable Optics (LPO). We do not view LPO as a risk. We believe that LPO will coexist with the traditional retimed market, and we plan to support both. We see the LPO solution supporting a subset of the market, primarily where the customer owns both ends of the link. In addition, a new half-retimed optical standard (HRO) is emerging, and if we see customer demand, we will support that as well. Each of these different standards is an architectural partitioning change but relies on the same underlying laser, modulator, and packaging technology, so deployment of one over the other does not have a significant impact on the Company.

27

◾ Co-Packaged Optics (CPO). To meet the anticipated needs of the future CPO market, we are well positioned to cover both single-mode and multimode infrastructure options for our customers. Our silicon photonics program, combined with our InP CW high-power lasers, will enable single-mode CPO applications or designs. In addition, given the successful track record of multimode pluggable transceivers in addressing short-reach applications such as AI/ML/HPC connectivity, we are also working on a multimode CPO option, powered by our VCSELs. We anticipate that the likely success of LPO will delay market adoption of CPO because LPO has most of the advantages of CPO (low power, low cost) while retaining all the valued advantages of a pluggable module (pay as you go, multiple solutions, multi-vendor ecosystem) that have ensured their success in the market. However, we will be prepared if or when CPO gains traction, as CPO is just a form-factor transition from LPO.

◾ Components. Revenue for our Datacom components was relatively unchanged from the preceding quarter. We expect growth for our Datacom components over the long-term to track growth for the overall Datacom market, i.e., we expect AI-related Datacom buildouts also to drive strong growth for our Datacom component revenue. Our Datacom components include lasers, photodiodes, and advanced optics solutions such as lenses, gratings, isolators, and circulators. As an example of one of the use cases for these advanced optical components, our advanced optics business unit has been supplying important components of optical circuit switches for the past several years.

2. Telecom Vertical. While the near-term outlook for the Telecom market remains challenged by customer inventory digestion and by project delays at CSPs, we remain confident regarding our longer-term Telecom outlook.

◾ Near-Term. Recovery in our Telecom revenue has lagged our previous expectations, and we now expect recovery in end demand will not arrive until late calendar 2024 or early calendar 2025.

◾ China. While the overall Telecom market remains challenging, the third quarter benefited from the ongoing 400G C+L backbone network upgrades by all three primary China CSPs that commenced in the preceding quarter. Currently these deployments are driving improvement in our pump lasers, Telecom components, and WSS product line where we enjoy market-leading technology. We expect to benefit from these new deployments well into fiscal 2025 in these product lines. We also have strong traction in China for our next-generation coherent transmission components that enable 800G and 400G high-performance applications. We expect these to ramp to significant volume in fiscal 2025.

◾ Long-Term. We expect our Telecom SAM to grow at a double-digit CAGR from fiscal 2024 to fiscal 2029 above the overall market growth rate. Underlying our expectation for a return to secular Telecom revenue growth starting in fiscal 2025 is a rebound in end market demand and meaningful incremental growth from new products that we expect to strengthen our competitive position in existing Telecom market segments. We also expect growth from new products that will expand our SAM by providing entreé into attractive—higher growth and higher margin—segments of the Telecom market. We discuss these drivers in further detail below.

28

◾ Robust Design and Qualification Activity. In the third quarter, we saw further expansion of design-in activity at both CSPs and OEM customers for our unique 100G ZR Telecom transceiver family. This platform is based on our internally developed Steelerton DSP, targeted for edge network platforms. Our industry pioneering 140 Gbaud IC-TROSA for 800G coherent applications has generated significant customer interest and design win opportunities.

◾ Share Gain. In Telecom, we are a vertically integrated market leader in several core businesses including our pump lasers, ROADMs, amplifiers, network monitoring, and WSS products along with our coherent transceivers and disaggregated solutions. We believe we are gaining share at many of our key customers with our current product set and our newer product platforms are seeing strong uptake in the industry.

◾ Exposure to Fast-Growth Segments. We are excited by our Telecom revenue growth outlook for fiscal 2025 and beyond as we are well positioned in key market segments and expect to benefit from the industry trend towards disaggregation, which benefits pluggable coherent transceivers and compact modular line systems, which are the fastest-growing segments of our Telecom market. High-speed coherent transmission continues to be the driving force of Telecom growth due to the bandwidth requirements of datacenter interconnect (DCI) and broadband networks. DCI is driving high growth for 400/800G pluggable coherent modules while edge and aggregation networks for broadband and 5G applications will drive 100G QSFP28 adoption. With the proliferation of AI datacenter clusters, we expect an increase in the demand for DCI and concomitantly for our coherent transceivers.

◾ Coherent Optical Modules. We are especially excited about the number and quality of customer design wins for our new 100G ZR and 400G ZR/ZR+ pluggable transceivers. Our 100G ZR QSFP28 transceiver is based on our own internally developed Steelerton DSP. We have secured design wins at the majority of the world’s Tier 1 NEMs for this new transceiver module. In addition, we currently are qualified and beginning to ramp shipments of our 400G ZR/ZR+ transceivers and expect to commence ramping production and commercial shipments of our new 100G ZR family of transceivers in fiscal 2025. We also have announced our new 800G ZR QSFP-DD coherent transceiver and shipped early samples in the first quarter of calendar 2024.

ELECTRONICS

Revenue. Revenue for our Electronics market decreased by 17% sequentially and by almost 50% year-over-year to $74 million for the third quarter driven by the previously disclosed design change at our largest Consumer Electronics customer that accounted for almost 10% of revenue in fiscal 2023.

Near-Term Demand Trends. In the near term, revenue in our Electronics market should stabilize from the winding down of the significant reduction in revenue in our Consumer Electronics revenue driven by the design change by our largest Consumer Electronics customer.

Long-Term. Our long-term outlook for robust growth in our Electronics market remains unchanged as discussed in greater detail below.

29

1. Automotive Vertical

◾ Revenue. Our revenue for our Silicon Carbide LLC subsidiary, which accounts for almost 100% of our Automotive vertical revenue, fell short of our expectations due to a power failure. This power failure will result in our falling short of our previous expectation for $300 million in Silicon Carbide LLC revenue for all of fiscal 2024.

◾ Market Overview. We remain both optimistic as to the long-term outlook for the silicon carbide market and confident as to our competitive position. Our Transactions with Mitsubishi Electric and DENSO, including each of their $500 million investments (in exchange for 12.5% ownership interests—25% in the aggregate—in Silicon Carbide LLC) and long-term supply agreements, have enhanced our confidence in our long-term revenue growth outlook for our silicon carbide business. That said, we have reduced our market growth outlook over the next five years. While sizable, approximately 50% EV sales growth in calendar 2023 fell short of industry expectations. EV demand has further moderated in calendar 2024 with new EV registrations having risen by only 15 percent in January, according to S&P Global Mobility. The primary drivers of this moderating outlook include a decrease in EV demand due to increasing interest rates, shifts in consumer preferences, shifts in global OEMs’ EV strategies, and a rise in regulatory uncertainty.

2. Consumer Electronics Vertical. In the Consumer Electronics market, our focus is on providing diode lasers for advanced sensing in mobile devices.

◾ Near-Term. As we have expected and highlighted over the past four quarters, our Consumer Electronics revenue has declined to 3% of total revenue from 10% of total revenue in fiscal 2023 driven by a design change at our largest Consumer Electronics customer. The silver lining is that this expected decline is nearing completion, which we expect to lead to stabilization in our Consumer Electronics revenue in the current fourth quarter and in fiscal 2025.

◾ Long-Term. Our longer-term outlook for Consumer Electronics, however, is driven by growth in breadth and depth of sensing adoption well beyond 3D sensing for smartphones. AI applications are currently driving the need for the data provided by advanced sensors that serve as the eyes and ears of AI/ML systems. In addition, AI’s emerging, powerful capabilities are underpinning new use cases to more effectively employ sensing functionality in a variety of markets and applications. This new market dynamic has triggered substantial activity to develop and deploy a variety of sensing solutions. These include health monitoring and biosensing, metaverse AR/VR hardware and wearables, automotive LiDAR and in-cabin sensing, and other emerging applications.

◾ Market Position. We are excited by our strategic engagements across all of these applications, with the breadth and pace of our sensing design-in activities at record levels. A key competitive differentiator for this market is provided by our broad semiconductor laser platform of integrated sensing solutions that spans from 850

30

nm to 2400 nm and three semiconductor laser material platforms that complement our expertise in integrated circuits (ICs), packaging, and full solutions for a variety of applications. We have a number of new platforms that we expect to enhance our already strong competitive position including multi-junction VCSELs, backside-emitting VCSELs, and InP sensors and detectors for biosensing.

◾ AR/VR/MR. We are expanding our offerings into AR/VR, wearable electronics, and domestic robotics, with illumination modules for diverse sensing applications as well as innovative optics solutions for AR/VR displays. During the third quarter, we continued to strengthen our strategic engagements, particularly in the AR/VR/MR and wearables market segments. As this technology gradually evolves, is more widely adopted, and integrates more advanced sensing features, we are well positioned to serve the market with differentiated solutions based on our opto-semiconductor and optics material platforms.

◾ Industry Leading 6-Inch Indium Phosphide Platform. We were the first supplier to announce a 6-inch indium phosphide platform that we plan to leverage in our future product roadmap for high-volume applications in advanced sensing, biosensing, and other emerging applications.

INSTRUMENTATION

Instrumentation Market Overview Webcast. As part of our ongoing effort to increase transparency and enhance the understanding of our investors, we plan to discuss our Instrumentation market in greater detail on May 14, 2024, on the third installment of our “Market Overview” webcast series, which will be webcast and available for replay afterward on our website at coherent.com/company/investor-relations/financial-webcasts.

Revenue. Third quarter revenue for our Instrumentation market was flat sequentially but decreased by approximately 2% year-over-year to $98 million. Both our Life Sciences and our Scientific Instrumentation verticals were relatively flat on a sequential basis. Our Life Sciences vertical was the primary driver of the year-over-year decrease.

Demand Trends. We remain excited regarding the long-term growth opportunity in the Instrumentation market. Near-term, demand in our Instrumentation market appears to have stabilized with a third straight quarter of just under $100 million in revenue. Elevated inventories appear to have been reduced to and may have reached normalized levels; however, we have yet to see a return to sequential or year-over-year growth, and our revenue remains approximately 15 – 20% below its fiscal 2023 level primarily due to macroeconomic uncertainty. We expect relatively stable Instrumentation revenue for the current fourth quarter of fiscal 2024 with a return to revenue commencing in fiscal 2025. We believe Instrumentation platform developers and end users have used the post-Covid recovery period to increase operating efficiencies and to shift their focus to new R&D projects that will start to drive incremental market demand within the next year. We expect a leveling off through the balance of fiscal 2024, with a return to growth in our Instrumentation market revenue commencing in fiscal 2025. We remain excited regarding the long-term growth opportunity in this market. Our long-term outlook for a return to high single-digit revenue growth in our Instrumentation market is discussed at greater length below.

31

1. Life Sciences Vertical. In the wake of the Coherent, Inc., acquisition, we have been showcasing our combined expansive bioinstrumentation portfolio and unparalleled integrated subsystem capabilities to the leading global biotechnology and medical instrumentation manufacturers. These customers have been excited about the integration of our broad portfolio of lasers, materials, optics, and thermoelectric products into subassemblies. These higher-level integrated solutions deliver significant value in terms of reduced cost and improved performance. Within the Biotechnology market, we continue to partner with leading innovators in flow cytometry, sequencing, PCR, and Imaging. Laser bookings for these applications increased by almost 30% sequentially and exceeded, albeit slightly, the year-ago level. We also have a variety of laser products to address therapeutic medical laser applications, ranging from semiconductor lasers for dermatology applications to excimer lasers for LASIK procedures. In ophthalmology, we are working with some of the largest companies in the industry to establish long-term supply agreements. Laser bookings also sequentially increased by almost 30% in the third quarter. The envelope of laser applications in therapeutics continues to expand and regulatory agencies worldwide continue to expand approvals. We are excited about our involvement in next-generation instrumentation that is enabling disease research and detection and leading the way to personalized medicine.

2. Scientific Instrumentation Vertical. We continue to see soft demand in our Scientific Instrumentation vertical within our Instrumentation market due to delayed capital expenditures and uncertain funding. For a third straight quarter, our Scientific Instrumentation revenue was in the low-$30 million range in the third quarter. Research in Life Sciences (neuroscience, cell biology, and disease studies) as well as exotic spectroscopy of materials and complex organic molecules drive most of the research expenditures in lasers. Demand remains subdued, but stable, tracking global government funding of research. Demand remains primarily focused on our exceptional line of scientific laser modules and systems to support cutting edge research.

REGIONAL TRENDS

The Americas: 57% of revenue in the quarter; sequential 10% increase; year-over-year 5% increase. The primary drivers of the sequential and year-over-year increases were the revenue ramp for our AI-related 800G Datacom transceivers, which more than offset a sequential and year-over-year revenue decline in the Americas region in our Materials segment that was largely driven by the expected reduction in demand in our Consumer Electronics revenue due to a design change by our largest Consumer Electronics customer (that we have highlighted for the past four quarters). Our revenue in the Americas region in our Lasers segment and in our Industrial and Instrumentation markets was relatively flat both sequentially and year-over-year.

Europe: 15% of revenue in the quarter; sequential 14% increase; year-over-year 25% decrease. Demand in the Industrial market continues to be challenged primarily due to ongoing macroeconomic uncertainty, with weakness in Germany having a particularly pronounced impact, a temporary slowdown in EUV demand, and continued softness in the Telecom vertical.

China: 13% of revenue in the quarter; sequential 5% decrease; year-over-year 14% increase. We saw the start of a rebound in our Telecom business in China in the second quarter that we expect to extend through the balance of fiscal 2024 and throughout fiscal 2025. Higher display fab utilization also resulted in higher service revenue for the quarter.

32

Korea and Japan: 13% of revenue in the quarter; sequential 2% decrease; year-over-year 9% decrease. Macroeconomic uncertainty continues to present near-term challenges in Korea and Japan. However, we have secured important design wins in our Semicap vertical in the region and are starting to see an increase in Display demand driven by further OLED penetration into smartphones, and adoption into laptop computers and tablets. We expect further improvement in the fourth quarter of fiscal 2024 led by stronger Laser service demand. Longer-term, we expect to see a significant increase in demand in Korea and Japan for our Industrial and Instrumentation businesses, especially from OLED Gen 6 fab expansions, new Gen 8 fab builds and, eventually, microLED builds.
