Key Takeaways Coherent aims to double InP manufacturing capacity by late 2026, then expand it more than twofold by 2027.Its six-inch wafer platform and 400G-per-lane technology target rising AI data center connectivity needs.COHR stock gained 162.6% in a year, while fiscal 2027 earnings estimates rose over the past 60 days. Coherent Corp. (COHR - Free Report) is strengthening its position in the artificial intelligence (AI) infrastructure market through capacity expansion and advanced optical technologies. The company's efforts to increase manufacturing output, improve connectivity performance and develop energy-efficient solutions should help it capitalize on rising demand for high-speed data center infrastructure.

Capacity Expansion Strengthens COHR's AI Growth ProspectsCoherent is accelerating production investments to meet increasing demand for optical components used in AI computing environments. The company aims to double its internal indium phosphide (InP) manufacturing capacity by the end of 2026, followed by another expansion exceeding twofold by 2027.

Its transition toward six-inch wafer manufacturing supports higher production yields than conventional three-inch processes. This manufacturing platform accommodates electro-absorption modulated lasers, continuous-wave lasers and photodiodes, helping Coherent improve production efficiency and address growing customer requirements.

Higher manufacturing capacity should enhance supply availability, strengthen customer relationships and create opportunities to capture additional spending from hyperscale data center operators.

Advanced Optical Technologies Support Competitive PositioningBeyond manufacturing expansion, Coherent is developing optical networking technologies designed to accommodate increasingly demanding AI workloads. Its portfolio includes silicon photonics, co-packaged optics and vertical-cavity surface-emitting lasers, providing customers with multiple connectivity options.

The company's 400G-per-lane technology enables faster information transfer, while its advanced optical transport solutions can quadruple fiber transmission capacity. These capabilities should support increasingly complex AI infrastructure requirements.

Energy Efficiency Adds Another Growth OpportunityCoherent is also advancing thermal management technologies and optical components that reduce energy consumption during data transmission. Such innovations could become increasingly important as operators seek to manage power requirements and infrastructure expenses.

Although substantial capital investments and manufacturing execution risks remain concerns, expanding production capabilities and technological innovation should strengthen Coherent's competitive standing in the AI infrastructure market.

Lumentum's order book is booked solid through early 2029, yet its stock is leading the entire AI optics sector lower today. When the most visible demand story in the group takes the hardest hit, something worth watching is happening inside…

Lumentum (NASDAQ:LITE | LITE Price Prediction) stock is down 10% to $996.95 in midday trading, leading a sharp retreat across artificial intelligence (AI) optical connectivity names. This drop stands out because Lumentum’s production capacity is spoken for through early 2029, and that combination of the deepest decline with the longest order visibility frames the selloff.

For an optics/photonics sector check, the Roundhill Photonics & Optics ETF (CBOE:LYTE) is down 7% to $23.11. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is essentially flat at $778.75, so the damage is staying inside one corner of the market. A 7% slide in the optical fund against a flat benchmark marks this as a group-specific selloff.

Meanwhile, Applied Optoelectronics (NASDAQ:AAOI) stock is down 7% to $101.50, falling less than Lumentum stock has. Additionally, Coherent (NYSE:COHR) stock is down 7% to $289.68, tracking Applied Optoelectronics stock almost step for step. All three had ranked among the strongest AI infrastructure winners heading into the decline.

A Sold-Out Order Book Meets Group Selling None of the three companies has issued a new press release ahead of the decline. That leaves selling spread across the whole optical group. These are the same AI expansion suppliers we profiled in a free report on seven non-chipmakers powering the boom, with the three stocks and the fund dropping in together. The slide in Lumentum stock is the steepest of the group, which makes it the clearest gauge of how hard the selling is landing.

On October 9, Lumentum’s chief executive said the company’s AI optical components are booked through early 2029, and the optical names rose that day. Coverage framed that rally around Lumentum being unable to keep up with AI demand (Barron’s). Those remarks are three days old and aren’t the cause of the current decline.

What the Peer Group Says About Lumentum As of its August 6 fact sheet, the Roundhill fund held Lumentum at 15.4% and Coherent at 15.2% of net assets, with Applied Optoelectronics at 2.1%. The fund and three stocks fell within a narrow range. The pattern points to group-level selling that hits every name regardless of its individual story.

Lumentum’s risk is that a stock up 170% year to date gives back the most when the group turns. At a forward P/E ratio of 43x, Lumentum stock carries little margin, and a full order book doesn’t protect a multiple. Lumentum shares also sit well above the 200-day moving average of $764.19, a sign of how far the run extended.

A bullish reading starts from an unchanged demand picture since October 9, because a sold-out order book signals demand running ahead of supply. Lumentum hosted its August 11 earnings call. On the call, Lumentum’s chief executive stated, “Pumped laser shipments surged more than 80% year over year, and we will remain effectively sold out for the foreseeable future, despite our rapid capacity expansion.” Management also said Lumentum reached its target operating model more than a quarter ahead of schedule.

What to Watch Next The key question for Lumentum is whether its booked capacity turns into reported revenue on schedule. Lumentum guided for current-quarter revenue of $1.225 billion to $1.275 billion after posting $1.006 billion last quarter, up 109.3% year over year. Hitting that range could show the order book translating into results on time.

The 10% drop in Lumentum stock shows how fast the optical names can reverse together, even with demand intact. Investors should hold small enough stakes that a group-wide decline stays within their risk tolerance.

Key Takeaways Coherent shares gained 8% in a month as AI infrastructure demand strengthens its optical-networking outlook.Coherent is ramping 1.6T transceivers, while 800G demand and subsystem opportunities broaden growth avenues.COHR has fiscal 2027 demand strongly committed, with customer purchase orders extending into calendar 2028. Coherent Corp. (COHR - Free Report) has emerged as a major beneficiary of the artificial intelligence infrastructure boom. The stock has surged 190% over the past year and gained another 8% in the past month, significantly outperforming its industry and the broader market.

Despite the sharp rally, the investment case remains supported by accelerating optical-connectivity demand, expanding manufacturing capacity and Coherent’s growing role in higher-value optical systems.

AI Infrastructure Offers a Long Growth RunwayThe AI opportunity extends well beyond the construction of new data centers. Existing facilities must continually upgrade as newer GPUs, switches and networking platforms require greater bandwidth. As AI clusters expand, more connections are needed among processors, racks, switches and facilities, increasing the importance of high-speed optical networking.

This trend plays directly into Coherent’s strengths. Its portfolio includes indium phosphide lasers, VCSELs, silicon photonics, specialty fiber, detectors and micro-optics. That broad technological base gives the company multiple ways to benefit as data-center operators shift toward faster, denser and more power-efficient network architectures.

Continued improvements in AI models, falling inference costs and broader commercial adoption could further stimulate computing requirements. As AI becomes embedded in more applications, network capacity should become increasingly critical alongside computing power.

PhotonLink Expands Coherent’s Value PropositionPhotonLink could strengthen Coherent’s position by moving the company further beyond individual components and into integrated optical subsystems. Combining internally developed technologies with integration, assembly and testing capabilities enables the company to capture a greater portion of the value created within an AI system.

This approach could also deepen customer relationships. Replacing a single component supplier is generally simpler than switching a provider whose subsystem has been designed and qualified within a broader architecture.

Coherent is also positioned across multiple technology pathways, including conventional pluggable optics, co-packaged optics, near-packaged optics and chip-to-chip connectivity. This diversified exposure reduces dependence on any single optical architecture becoming the dominant industry standard.

High-Speed Product Ramps Strengthen Near-Term ProspectsCoherent’s immediate earnings momentum should primarily come from products already entering large-scale production. The 1.6T transceiver ramp is particularly important, while demand for 800G products continues to expand. Co-packaged optics, optical circuit switching and Multi Rail technologies provide additional avenues for growth as AI networks become more complex.

Demand visibility is another encouraging factor. Fiscal 2027 requirements are already strongly committed, while customer purchase orders extend into calendar 2028. Longer-term agreements stretch further into the decade, with some incorporating minimum purchasing commitments and predetermined pricing.

The bigger challenge appears to be satisfying demand. Coherent increased InP laser production by nearly 80% year over year during the June quarter and continues to expand six-inch InP capacity. Higher yields from six-inch wafers could also improve manufacturing economics as volumes rise.

Earnings Momentum Supports the Investment CaseThe Zacks Consensus Estimate projects fiscal 2027 revenues of $10.68 billion, indicating 50% year-over-year growth. Revenues are expected to advance another 35% in fiscal 2028.

Profit expectations are similarly robust. Fiscal 2027 EPS is projected at $9.38, indicating 67.2% growth, followed by another 46% increase in fiscal 2028. These estimates suggest that rising AI exposure, greater manufacturing utilization and operating leverage could translate strong demand into accelerating profitability.

COHR trades at roughly 32.06 times forward earnings compared with the industry’s 20.77 times. The premium is considerable, but Coherent increasingly looks different from the more cyclical hardware supplier of the past. Greater revenue visibility, stronger margins, long-term customer commitments and improving cash generation provide greater support for the valuation.

Two U.S.-Listed Peers to WatchLumentum Holdings (LITE - Free Report) is a relevant optical-networking peer with significant exposure to cloud and data-center connectivity. Lumentum Holdings competes in high-speed optical components and related technologies, making it sensitive to many of the AI-driven bandwidth trends supporting COHR. Lumentum Holdings therefore provides investors with another way to gauge demand across the rapidly evolving optical-networking market.

Applied Optoelectronics (AAOI - Free Report) is another U.S.-listed peer tied closely to data-center optics. Applied Optoelectronics benefits from demand for higher-speed optical products used by hyperscale customers, linking its growth prospects to expanding data-center investment. Applied Optoelectronics is therefore a useful comparison when assessing how effectively optical suppliers are converting AI infrastructure spending into revenue growth and stronger profitability.

Is COHR Stock a Buy?Coherent appears well positioned to remain a compelling buy as AI infrastructure spending expands and optical networking becomes more critical to next-generation data centers. Demand visibility, rising high-speed transceiver volumes, broader subsystem exposure and improving manufacturing efficiency strengthen the earnings outlook. The company also benefits from a deeper role in customer architectures, which can support stickier relationships and better margins. Valuation is elevated, but the premium looks increasingly supported by faster growth, stronger profitability and long-term customer commitments. For investors willing to tolerate volatility after the rally, Coherent still offers an attractive way to participate in the AI infrastructure buildout.

COHR currently sports a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks #1 Rank stocks here.

A month has gone by since the last earnings report for Coherent (COHR - Free Report) . Shares have lost about 10.4% in that time frame, underperforming the S&P 500.

But investors have to be wondering, will the recent negative trend continue leading up to its next earnings release, or is Coherent due for a breakout? Well, first let's take a quick look at its latest earnings report in order to get a better handle on the recent drivers for Coherent Corp. before we dive into how investors and analysts have reacted as of late.

COHR Q4 Earnings Beat EstimateCoherent reported fiscal fourth-quarter adjusted EPS of $1.74, which increased 74% year over year and 23.4% quarter over quarter, beating the Zacks Consensus Estimate by 7.4%. Revenues crossed $2 billion, beating the Consensus Estimate by 2.7% and increasing 33.8% year over year and 13.3% sequentially.

COHR’s Revenue Growth Accelerates Into the Year-EndFull-year revenues rose 22.5% year over year to a record $7.1 billion from $5.8 billion. Pro forma growth was stronger at approximately 28%, reinforcing that the underlying portfolio expanded faster than the reported total after accounting for business sales.

The Datacenter & Communications segment provided nearly all the momentum. Quarterly segment revenues climbed to $1.6 billion, up 58.6% year over year and 18.6% quarter over quarter. It represented roughly 79% of consolidated revenues, compared with about 67% a year earlier.

Industrial revenues moved in the opposite direction, falling 15.8% year over year and 3% sequentially to $430.5 million. For the full year, Datacenter & Communications advanced 40.5% to $5.275 billion, while Industrial declined 10.3% to $1.8 billion. Coherent’s growth profile is therefore becoming more concentrated around AI networking and optical connectivity.

Margin Expansion Made the Growth More ValuableThe earnings quality improved alongside revenues. GAAP gross margin expanded to 38.5%, up 277 basis points year over year and 82 basis points sequentially. Adjusted gross margin reached 40.2%, improving 215 basis points annually and 66 basis points from the fiscal third quarter.

Manufacturing yields, lower input costs, pricing actions and progress on six-inch indium phosphide production contributed to the expansion. The six-inch platform is especially important because it can produce roughly four times the output at about half the cost of the older three-inch process.

Adjusted operating income increased 62.1% year over year and 21.8% sequentially to $446 million. The corresponding operating margin reached 21.8%, expanding 381 basis points year over year and 152 basis points quarter over quarter.

Adjusted net income rose 82.7% annually and 27.2% sequentially to $351 million. GAAP EPS improved to $1.19 from a loss of $0.83 one year earlier and $0.97 in the preceding quarter.

Capacity Spending Raises Both Potential and RiskIndium phosphide production remains the principal constraint, although output is scheduled to double year over year during the current quarter. Demand visibility extends into calendar 2028, supported by long-term agreements running through the decade. Additional growth should come from 800-gigabit and 1.6-terabit transceivers, optical circuit switching, co-packaged optics, multi-rail systems and the PhotonLink platform.

Supporting those opportunities requires substantial spending. Fourth-quarter capital expenditures reached $556 million, while full-year additions to property, plant and equipment surged 150.2% to $1.103 billion. Annual operating cash flow nevertheless fell 87.5% to $79.5 million.

Inventory increased 79.5% year over year to $2.581 billion, considerably faster than revenues. Although expanding inventory can support a rapid production ramp, it also raises working-capital and demand-forecasting risk. Positively, total debt declined approximately 12.6% to $3.222 billion and cash increased 27.8% to $1.162 billion.

COHR’s Guidance Points to Another Step-UpFor the first quarter of fiscal 2027, Coherent expects revenues of $2.2 billion to $2.4 billion. The $2.3 billion midpoint implies approximately 12.4% sequential growth and about 45.6% growth from first-quarter fiscal 2026 revenues of $1.58 billion. The comparison is not perfectly like-for-like because of portfolio changes, but the acceleration remains substantial.

The company expects an adjusted gross margin of 39.5%-41.5%. Its 40.5% midpoint would represent a modest 30-basis-point sequential improvement. Projected adjusted EPS of $1.85-$2.05 implies midpoint growth of 12.1% from the fiscal fourth quarter and approximately 68% year over year.

Guidance exceeded the prior quarter’s scale and established a credible path toward a quarterly revenue run rate above $3 billion by fiscal 2027’s end.

How Have Estimates Been Moving Since Then?In the past month, investors have witnessed a upward trend in fresh estimates.

The consensus estimate has shifted 10.08% due to these changes.

VGM ScoresAt this time, Coherent has a poor Growth Score of F, however its Momentum Score is doing a lot better with a C. Charting a somewhat similar path, the stock has a grade of D on the value side, putting it in the bottom 40% for this investment strategy.

Overall, the stock has an aggregate VGM Score of F. If you aren't focused on one strategy, this score is the one you should be interested in.

OutlookEstimates have been trending upward for the stock, and the magnitude of these revisions looks promising. It comes with little surprise Coherent has a Zacks Rank #2 (Buy). We expect an above average return from the stock in the next few months.

Performance of an Industry PlayerCoherent belongs to the Zacks Technology Services industry. Another stock from the same industry, Dave Inc. (DAVE - Free Report) , has gained 7.4% over the past month. More than a month has passed since the company reported results for the quarter ended June 2026.

DAVE INC reported revenues of $170.8 million in the last reported quarter, representing a year-over-year change of +29.7%. EPS of $4.12 for the same period compares with $3.14 a year ago.

For the current quarter, DAVE INC is expected to post earnings of $4.35 per share, indicating a change of +2.6% from the year-ago quarter. The Zacks Consensus Estimate has changed +2% over the last 30 days.

DAVE INC has a Zacks Rank #3 (Hold) based on the overall direction and magnitude of estimate revisions. Additionally, the stock has a VGM Score of C.

Coherent just handed back a third of its value in three months without a single crack in its operating story, and Wall Street is responding by piling on price target upgrades instead of downgrades. Something about this setup does not…

Coherent (NYSE:COHR | COHR Price Prediction) trades at $268.64, while Wall Street’s average 12-month price target sits at $416.09. That gap implies roughly 55% upside, and the Street-high call from Rosenblatt Securities at $500 takes the potential move closer to doubling.

Coherent is the pure-play photonics vendor supplying the lasers, transceivers, and optical subsystems that stitch together AI datacenters. Its Datacenter & Communications segment produced 79% of last quarter’s revenue and grew 59% year over year. Coherent also joined the S&P 500 this year, adding a passive-flow tailwind to an already crowded bull story.

None of that stopped the stock from cratering over the summer, which is why the dislocation now looks so extreme. Coherent sits inside the broader AI infrastructure buildout, and we profiled seven of the picks-and-shovels suppliers powering that trade, from optics to cooling, in a free report you can grab here.

A 36% Three-Month Gut Punch on No Fundamental Break Shares fell 35.64% over the past three months, sliding from $417.43 to current levels. That is a peer-leading drawdown, and it happened without a single crack in the operating story.

The catalysts were technical. Coherent completed a $2 billion common stock issuance that added supply pressure. AI-optical names had rallied violently into August, and profit-taking spread across the group. The Q4 earnings report on August 12 actually beat, with non-GAAP EPS of $1.74 versus the $1.6171 estimate and revenue of $2.045 billion up 33.74% year over year. The market still faded the earnings report, worried about capex intensity and the 87.45% collapse in full-year operating cash flow tied to $1.1 billion in capacity spending.

Rosenblatt’s $500 Call and Why the Sell Side Is Digging In With upside to the average target now above 50% and Rosenblatt’s high call implying an 86% move, the bull thesis has become the centerpiece of the story. Rosenblatt lead analyst Mike Genovese lifted his target from $425 to $500, citing accelerating 800G and 1.6T transceiver shipments, Coherent’s vertical integration in six-inch indium phosphide wafers, and structural gross-margin expansion.

Management’s own commentary supports the aggressive math. CEO Jim Anderson told investors bookings extend into calendar 2028, long-term agreements run through the end of the decade, and Coherent has seen “absolutely no push out of CPO demand.” Management is targeting the first $3 billion revenue quarter by the end of fiscal 2027. Consensus EPS estimates for fiscal 2027 have been revised up from $8.0885 to $9.4061 over the past 90 days.

Of Coherent’s 23 covering analysts, 4 rate the stock Strong Buy, 14 Buy, and 5 Hold, with no Sell ratings. Recent activity has been dominated by upward revisions, not downgrades. Targets remain projections, and the direction of travel is one-sided.

Photonics Peers Tell a Split-Screen Story The AI-optical group did not sell off in unison. Coherent’s peers actually held up, which frames its 35% drawdown as a name-specific reset.

Lumentum Holdings (NASDAQ:LITE) has ripped 136.19% year to date to $870.58. Its analyst target of $1148.30 implies about 32% upside, and the ratings tilt heavily bullish across 26 covering analysts. Wall Street sees less headroom here than at Coherent.

Fabrinet (NYSE:FN) is the outlier, down 13.16% YTD at $395.35 despite a blowout fiscal Q4. Its $734.11 target implies roughly 86% upside, the largest in the group and effectively tied with Coherent’s Rosenblatt call.

Ciena (NYSE:CIEN) trades at $354.16 with a $557.29 target and about 57% implied upside, roughly matching Coherent’s average-target gap. Ratings are more mixed, with one Strong Sell in the mix.

Fabrinet holds the largest analyst-implied upside in the peer group, but Coherent’s setup is uniquely attractive: comparable upside to Ciena on average, and the biggest post-selloff reset of the four.

Coherent’s Data Points in Plain English Coherent trades at $268.64 against a consensus 12-month target of $416.09, roughly 55% below where the average of 23 analysts thinks it should be. Rosenblatt’s Street-high $500 puts the ceiling near 86% above spot.

Despite the recent damage, COHR is still up 45.55% year to date, well ahead of the S&P 500’s 12.21% gain. The one-year return sits at 205.97%. Forward P/E is 27x against a fiscal 2027 consensus EPS of $9.4061.

Where I Actually Land on Coherent Here The bull case firms up if the indium phosphide ramp lands on schedule, CPO revenue begins contributing in the December quarter as guided, and gross margin clears the 42% target model. That combination unlocks the fiscal 2028 EPS of $13.9489 Street consensus is now underwriting, and $416 becomes a reasonable print. The thesis weakens if capex intensity keeps operating cash flow depressed, hyperscaler order timing wobbles, or CPO adoption slips into late 2027.

My lean is bullish. The selloff looks like supply-driven digestion after a 200% run, with the demand story intact, and management’s backlog visibility is the deepest it has been. The Rosenblatt double reads as an upside scenario, and 55% to the average target with a booked-out fiscal 2027 is a setup worth owning.

SK Hynix just published a technology roadmap that redraws where optics belong inside an AI system, and one company supplies nearly every component required to build it.

The investment case for Coherent Corp. (NYSE: COHR) | COHR Price Prediction has largely centered on one increasingly important problem: artificial intelligence processors are producing data faster than conventional electrical connections can move it. That imbalance has driven rapid demand for Coherent’s 800-gigabit and 1.6-terabit optical transceivers, indium phosphide lasers, optical circuit switches, and silicon-photonics components.

A new technology roadmap from SK hynix Inc. (NASDAQ: SKHY) suggests that Coherent’s opportunity could become substantially broader.

On August 20, SK hynix announced that it had collaborated with researchers from several leading universities on a co-packaged-optics roadmap published in Nature Electronics. The paper describes an AI architecture in which optical links move beyond communications between conventional network switches and directly connect separate pools of processors and memory.

That distinction is the investment hook. Coherent is already benefiting as data centers replace copper connections with optical transceivers. Nvidia has also moved CPO into production for networking switches. SK hynix is now describing an additional stage in which photonics becomes part of the architecture connecting processors with memory resources.

If the industry follows this direction, optics will not remain confined to the edges of AI servers and switches. It will move progressively closer to the most valuable components in the system: accelerators and high-bandwidth memory.

Coherent is positioned across nearly every critical portion of that transition. The company supplies high-power indium phosphide lasers, external laser-source modules, silicon-photonics components, microlens arrays, fiber-attach units, polarization-maintaining fiber, optical circuit switches, and complete optical transceivers. It has demonstrated a 6.4-terabit silicon-photonics CPO system and has secured very-high-volume, multiyear orders from a leading AI data center customer.

The market has already recognized Coherent as an AI optical-transceiver company. SK hynix’s roadmap creates a more expansive possibility: Coherent could become an enabling supplier for the optical fabric connecting processors, switches, and memory throughout the AI system.

SK Hynix Is Looking Beyond HBM SK hynix became one of the largest financial beneficiaries of the AI boom by solving the first major memory bottleneck. Its high-bandwidth memory places vertically stacked DRAM close to the processor and connects it through an extremely wide interface, allowing substantially more data to reach the accelerator than conventional server memory can provide.

That position has generated extraordinary cash flow. On August 19, SK hynix announced a KRW40 trillion, or approximately $28.7 billion, share-repurchase program. The company will buy and cancel 24.07 million common shares, representing approximately 3.3% of its issued shares.

The cancellation is important because those shares will be permanently removed rather than held in treasury for possible reissuance. SK hynix also committed to returning more than 50% of cumulative free cash flow generated during its 2025–2027 shareholder-return period through repurchases, cancellations, and dividends.

One day after announcing the buyback, however, SK hynix focused attention on what comes after HBM.

The company’s CPO technology roadmap argues that the AI industry is moving from chip-level competition toward system-level competition. HBM increased bandwidth between memory and an accelerator, but increasingly large AI systems must also move data between thousands of accelerators, multiple memory resources, storage systems, and network switches.

Electrical signals encounter greater power consumption, heat generation, and signal-integrity problems as speeds and distances increase. The industry can continue improving copper connections, but the physical limitations become progressively more difficult and expensive to overcome.

Optical connections carry more data over longer distances while consuming less energy per bit. CPO moves the optical conversion closer to the processor or switching silicon, minimizing the distance traveled electrically.

SK hynix’s proposed architecture goes further than the CPO switches attracting most current investment attention. It describes a photonic interposer that directly connects computing resources in an XPU pool with memory resources in a separate memory pool.

This would allow processors to access larger and more flexible quantities of memory rather than depending entirely upon the HBM physically attached to each accelerator. The architecture remains a roadmap rather than a commercial product, but its direction is important. The world’s leading HBM supplier believes future memory systems will increasingly require optical as well as electrical connectivity.

Why This Matters More Than Another CPO Announcement Investors have been hearing about CPO for several years, creating understandable skepticism about whether every new roadmap represents a meaningful commercial development. In this case, two factors make the announcement more important.

First, CPO has entered production.

In May, Nvidia Corp. (NASDAQ: NVDA) announced that its Spectrum-X Ethernet Photonics switches were in production as part of the Vera Rubin infrastructure ramp. The platform uses CPO and 200-gigabit-per-second serializer/deserializer technology to support networks connecting extremely large numbers of AI accelerators.

Nvidia says Spectrum-X Ethernet Photonics provides five times better power efficiency, five times longer AI-system uptime, and 1.3 times faster deployment than networks based on traditional transceivers. CoreWeave, Lambda, and Oracle Cloud Infrastructure are among the first identified adopters.

The production announcement moved CPO beyond a laboratory demonstration or conference prototype. Data center customers can now begin deploying the technology within commercial AI infrastructure.

Second, SK hynix is not an optical-component manufacturer attempting to create demand for its own products. It is the leading supplier of the HBM used with Nvidia accelerators. Its decision to publish a roadmap for processor-to-memory optical architecture provides independent confirmation that data movement is becoming a system-level constraint.

Nvidia validates the near-term CPO market in network switches. SK hynix expands the long-term opportunity toward memory and compute.

Coherent participates in both.

Coherent Has More Than a Laser Position The immediate temptation is to frame CPO primarily as an external-laser opportunity. That interpretation is incomplete for Coherent because the company supplies a considerably broader collection of components.

A CPO system must generate light, deliver it to the optical engine, modulate it with data, align it precisely, and transfer it into optical fiber. Each function requires specialized active and passive components.

High-power continuous-wave indium phosphide lasers provide the light. External laser-source modules move those lasers away from the hot switch package, improving thermal stability, reliability, and serviceability. Silicon-photonics integrated circuits modulate the light with data. Microlens arrays and fiber-attach units align the optical signal with the fiber, where extremely small deviations can increase loss and impair performance.

Coherent participates at each of these levels.

The company produces high-power indium phosphide continuous-wave lasers at its Sherman, Texas, facility. It integrates lasers with isolators and thermoelectric cooling into external laser-source modules. It designs silicon-photonics products and manufactures microlenses, polarization-maintaining fiber, prisms, and fiber-attach assemblies.

Coherent’s vertical participation does not guarantee that it will supply every component in a production platform. Nvidia and other customers will maintain multiple suppliers to reduce risk and preserve negotiating leverage. However, Coherent’s breadth gives it several opportunities to win content within the same system.

It also allows Coherent to optimize components as a coordinated optical platform instead of developing each product independently. That can become increasingly important as CPO architectures require tighter alignment, lower optical loss, higher laser power, and greater reliability.

According to Table 1, the optical transition is developing across several increasingly demanding stages. Coherent already generates substantial revenue from pluggable transceivers, is positioned in commercial CPO switching platforms, and could eventually address processor-to-memory optical architectures of the type proposed by SK hynix.

The progression matters because each stage increases the amount of optical content required to support an AI system. Pluggable optics connect discrete pieces of equipment. Switch CPO moves photonics onto the switching package. Processor-to-memory photonics could embed optical communication more deeply within the compute architecture.

That is why Coherent describes CPO as an expansion of its serviceable available market rather than merely a replacement for existing transceivers.

A Potential $15 Billion Market At its March 2026 Optical Fiber Communication investor presentation, Coherent estimated that the CPO serviceable available market could exceed $15 billion by 2030.

That forecast is a company estimate rather than an independent guarantee, but it illustrates the scale of the opportunity management believes is developing. More importantly, the estimate was based principally on CPO and near-packaged-optics adoption in switches and processors. SK hynix’s proposed memory-pooling architecture could increase the ultimate market by adding more optical interfaces around memory.

The addressable market should not be interpreted as revenue Coherent will automatically capture. The supply chain includes Lumentum Holdings Inc. (NASDAQ: LITE) in high-power lasers and external laser sources, Corning Inc. (NYSE: GLW) in optical fiber and connectivity, TSMC in silicon-photonics manufacturing and advanced packaging, and numerous companies supplying connectors, fiber assemblies, and optical engines.

Coherent’s advantage is not that it operates without competitors. It is that it competes across more individual CPO components than most publicly traded alternatives.

Lumentum may possess particularly strong exposure to the high-power external-laser bottleneck. Corning supplies essential fiber, alignment grooves, and connectivity products. Coherent combines laser and passive-optical technologies with transceivers, silicon photonics, fiber attachment, and advanced manufacturing.

That breadth gives Coherent several potential revenue paths as customers determine which CPO architectures reach volume production.

The Commercial Evidence Is Already Building Coherent is not relying solely upon SK hynix’s future roadmap.

The company disclosed at OFC 2026 that it had secured very-high-volume, multiyear orders from a market-leading AI data center customer for CPO solutions. The products include high-power continuous-wave lasers and external laser sources manufactured using Coherent’s expanding 6-inch indium phosphide platform.

Coherent has also demonstrated a socketed 6.4-terabit silicon-photonics CPO platform. The demonstration combined an external laser source, an internally produced indium phosphide continuous-wave laser, an isolator, thermoelectric cooling, polarization-maintaining fiber, microlenses, and fiber-attach technology.

The importance is not simply the 6.4-terabit data rate. The demonstration showed that Coherent can integrate active and passive technologies drawn from multiple portions of its portfolio into a working CPO architecture.

The company’s Sherman facility is ramping high-power continuous-wave lasers on 6-inch indium phosphide wafers. Moving from 3-inch to 6-inch wafers increases the available manufacturing area by approximately four times, allowing more devices to be fabricated during each process cycle. Coherent has reported that yields on its 6-inch platform have exceeded those of its older 3-inch lines.

This manufacturing transition is essential because the CPO opportunity cannot be monetized through technical demonstrations alone. Coherent must produce large quantities of high-power lasers with consistent performance, reliability, and acceptable cost.

Nvidia’s March agreement provided additional validation. The company invested $2 billion in Coherent as part of a multiyear, nonexclusive strategic partnership covering advanced optical technology, manufacturing expansion, research and development, and future capacity access. The agreement also includes a multibillion-dollar purchase commitment.

Nvidia made a parallel investment in Lumentum, confirming that it intends to maintain multiple laser suppliers. But its willingness to invest directly in Coherent demonstrates that the company’s manufacturing capacity and technology have become strategically important to Nvidia’s AI roadmap.

Coherent’s Current Revenue Acceleration CPO offers substantial future upside, but investors do not need to wait for processor-to-memory photonics to justify Coherent’s current AI position. Its established optical business is already converting higher AI infrastructure spending into revenue growth and margin expansion.

During Coherent’s fiscal fourth quarter, Data Center and Communications revenue increased 59% year over year and 19% sequentially to $1.62 billion. The segment reached 79% of total company revenue, compared with a much smaller contribution from the Industrial business.

Total quarterly revenue increased 34% year over year to $2.05 billion, or 42% on a pro forma basis excluding divested operations. Non-GAAP gross margin expanded by 215 basis points to 40.2%, while adjusted earnings increased to $1.74 per share from $1.00 one year earlier.

For fiscal 2026, Data Center and Communications revenue increased approximately 40% to $5.27 billion. Coherent’s full-year revenue reached $7.12 billion, increasing 23% on a reported basis and approximately 28% on a pro forma basis.

Management guided fiscal first-quarter 2027 revenue to between $2.2 billion and $2.4 billion, with non-GAAP earnings of $1.85 to $2.05 per share. The midpoint of the revenue range would represent another sequential increase of approximately 12%.

The current growth is being driven primarily by conventional optical products rather than the longer-term CPO opportunity. Coherent is shipping 800G transceivers while rapidly ramping 1.6T products across multiple customers. The higher-speed products carry higher initial average selling prices and can improve product mix as manufacturing yields rise.

This provides an important balance to the investment case. Coherent does not require immediate mass adoption of SK hynix’s photonic-memory architecture. Its current optical business is already growing quickly, while CPO and processor-to-memory connectivity add longer-term optionality.

From SiC Tailwinds to AI Optical Growth The longer-term revenue record shows how completely Coherent’s growth engine has changed. The fiscal 2022 baseline is important because the Materials operation initially expanded strongly in fiscal 2023 before weaker consumer electronics and the EV-driven SiC retrenchment reduced revenue.

According to Table 2, Networking revenue increased 55.6% from fiscal 2022 through fiscal 2025, while Materials declined 14.7% and legacy Coherent Lasers declined 5.6%. The smaller decline in Lasers should not be interpreted as evidence that the acquired business produced a superior return. II-VI paid approximately $7.1 billion for legacy Coherent and assumed substantial debt and integration costs for a business that subsequently generated little revenue growth.

Note: The fiscal 2022 Lasers figure represents legacy Coherent’s trailing-12-month pro forma revenue. Networking and Materials reflect II-VI’s recast segment results.

The Materials decline does not invalidate the SiC investment thesis that existed in 2023. Materials initially increased 20.6%, from $1.119 billion in fiscal 2022 to $1.350 billion in fiscal 2023, consistent with Coherent’s disclosure that SiC revenue had grown more than 40%.

Most of the fiscal 2024 Materials contraction resulted from a significant consumer-electronics customer’s design change. The later weakness reflected slowing automotive and SiC demand as the U.S. EV market retrenched. That reversal was becoming identifiable in early 2024 before it became fully visible in Coherent’s annual results.

Materials also retained considerable economic value. Fiscal 2025 Materials revenue declined 6%, but segment profit increased 19% to $355 million because of better product mix, improved pricing, and lower manufacturing costs.

Networking produced a fundamentally different result. Revenue increased from $2.198 billion in fiscal 2022 to $3.421 billion in fiscal 2025, before Data Center and Communications accelerated further in fiscal 2026.

Optical networking became the growth platform that SiC appeared capable of becoming before the EV downturn. The difference is that optical demand is now being supported simultaneously by Nvidia’s product roadmap, hyperscaler capital spending, the transition from 800G to 1.6T transceivers, CPO commercialization, and the potential movement of photonics toward processors and memory.

The historical numbers therefore add an important dimension to the SK hynix announcement. Coherent is not attempting to build an optical business around an unproven technology roadmap. It is extending the strongest-performing part of its existing portfolio into another layer of AI infrastructure.

Why the Market Could Still Be Underestimating Coherent Coherent’s share price already reflects substantial enthusiasm for AI optical networking. The stock cannot be characterized as an undiscovered or conventionally inexpensive company based on trailing GAAP earnings.

The possible mispricing lies elsewhere. Investors may be valuing Coherent primarily as a supplier of faster generations of pluggable optical transceivers. That captures the existing 800G-to-1.6T transition but does not necessarily capture the full expansion of optical content inside future AI systems.

If CPO merely replaces pluggable transceivers one-for-one, the investment opportunity would be less compelling because revenue would migrate between product categories rather than create a substantially larger market.

Coherent’s argument is that CPO expands the market because optics begins replacing copper in additional connections. The optical content moves from the front panel of a switch closer to the switching ASIC, then toward processors, and potentially toward pools of memory.

SK hynix’s roadmap supports that argument. It does not present CPO as a different packaging format for the same network connection. It presents optical communication as part of a restructured computing and memory architecture.

That is a significantly larger vision—and one in which Coherent’s broad component portfolio becomes more valuable.

Risks Remain Substantial The principal risk is adoption timing. SK hynix’s photonic-interposer architecture remains a technology roadmap, not a product with a disclosed manufacturing date or customer commitment. Processor-to-memory optical links will require new standards, packaging techniques, memory controllers, software, and system architectures.

CPO also creates reliability and serviceability challenges. Integrating optical engines close to a hot switch ASIC can complicate manufacturing and repair. External laser sources solve part of the problem by keeping replaceable lasers away from the hottest silicon, but fiber coupling and optical alignment must remain stable under demanding operating conditions.

Customer concentration presents another concern. AI optical demand is driven by a relatively small number of hyperscalers and accelerator-platform companies. Large customers can change architectures, qualify competing suppliers, or alter deployment schedules. Nvidia’s agreement is nonexclusive, and Coherent must continue competing with Lumentum and other suppliers for content.

Coherent is also investing heavily to expand capacity. Capital expenditures reached approximately $1.10 billion during fiscal 2026, while rapid growth increased working-capital requirements. Converting orders into profitable revenue will depend upon manufacturing yields, utilization, and execution across multiple facilities.

Finally, strong demand does not eliminate valuation risk. Investors have already rewarded optical companies for anticipated AI growth. Any delay in 1.6T deployments, CPO production, or hyperscaler capital spending could produce substantial share-price volatility.

These risks argue against treating the SK hynix announcement as an immediate earnings event. Its importance is strategic: it increases the number of AI connections that could eventually become optical.

Investor Takeaway SK hynix’s announcement is not simply another endorsement of CPO. It expands the technological objective.

Nvidia has already moved co-packaged optics into production for Ethernet switches. SK hynix is now proposing an architecture in which optical links connect processors directly with pooled memory resources. The combination suggests that photonics is progressing from data center networking toward the internal architecture of AI computing systems.

Coherent is unusually well positioned for that progression because it does not depend upon a single optical component. The company supplies indium phosphide lasers, external laser sources, silicon photonics, microlenses, optical circuit switches, polarization-maintaining fiber, and fiber-attach assemblies. It has demonstrated an integrated 6.4T CPO platform and has secured very-high-volume, multiyear orders from a leading AI data center customer.

The revenue record supports the thesis. Networking increased 55.6% between fiscal 2022 and fiscal 2025, while the company’s Data Center and Communications segment grew another 59% year over year during the latest quarter. Total quarterly revenue reached $2.05 billion, and management expects as much as $2.4 billion in the current quarter. Nvidia’s $2 billion investment provides additional validation and supports the capacity expansion required to meet future demand.

The SK hynix roadmap adds something not fully reflected in those current results. If optical connectivity moves from switches toward processors and memory, Coherent’s addressable market increases without requiring the company to abandon its existing transceiver business. Pluggable optics, optical circuit switching, CPO, and processor-to-memory photonics can coexist as separate layers of the same AI infrastructure.

Coherent estimates that CPO alone could become a market exceeding $15 billion by 2030. SK hynix’s entry into the discussion suggests that even this estimate may not capture the full long-term opportunity if memory architectures become increasingly optical.

Coherent is already helping AI systems move data between servers and switches. SK hynix has now provided a roadmap for moving optics directly toward compute and memory. That development makes Coherent more than a beneficiary of the current transceiver cycle. It positions the company for a broader architectural change in how future AI systems are connected.

Key Takeaways Coherent's fiscal Q4 revenues rose 34% to $2.05B, led by 59% growth in Datacenter & Communications.Datacenter & Communications supplied nearly 79% of revenue, while adjusted operating margin rose to 21.8%.COHR sees fiscal Q1 2027 revenues of $2.2-$2.4B, while Industrial sales fell 16% year over year. Coherent Corp.’s (COHR - Free Report) quarterly revenues climbed to $2.05 billion in the fourth quarter of fiscal 2026, up 34% year over year and 13% sequentially. The standout was Datacenter & Communications, where sales reached $1.62 billion, increasing 59% from the prior-year quarter and 19% from the fiscal third quarter. The business supplied nearly 79% of total revenues, underscoring how rapidly AI infrastructure demand is reshaping Coherent’s portfolio.

That momentum is also lifting profitability. GAAP gross margin expanded 277 basis points year over year to 38.5%, while adjusted operating margin improved 381 basis points to 21.8%. Management expects first-quarter fiscal 2027 revenues of $2.2-$2.4 billion and adjusted earnings of $1.85-$2.05 per share. The outlook suggests optical-connectivity demand and capacity additions can extend the growth run. However, Industrial revenues fell 16% year over year to $431 million, leaving results increasingly dependent on datacenter spending, production ramps and customer execution.

Two Optical Peers to WatchAmong optical peers, Lumentum Holdings (LITE - Free Report) and Applied Optoelectronics (AAOI - Free Report) provide useful benchmarks. Lumentum Holdings generated fiscal fourth-quarter revenues of $1.01 billion, more than doubling year over year, and guided to further sequential growth. Applied Optoelectronics posted second-quarter revenues of $191.9 million, up 86%, as its 800G ramp strengthened.

Lumentum Holdings offers broader scale and stronger margins, whereas Applied Optoelectronics brings faster expansion from a smaller base. Coherent’s greater revenue scale is an advantage, but the progress of both rivals shows that competition for AI-optics demand remains intense. Sustaining leadership will require converting demand into consistent margins and cash.

The artificial intelligence (AI) infrastructure build-out is hitting a physical wall. As next-generation processors push past the 1,000-watt threshold, legacy packaging substrates are failing to dissipate the extreme heat generated by these clusters. Data center operators are discovering that without advanced thermal materials, the world's most powerful chips will throttle themselves to prevent hardware failures. Effective thermal management is no longer an optional upgrade; it is a hard constraint on performance.

While the broader market fixates on software and chip design, the physical bottlenecks of AI hardware present a compelling investment thesis. Recent macroeconomic jitters have dragged shares of Coherent Corp. NYSE: COHR down about 12% in the past five days. This price drop is due to broader de-risking in the semiconductor sector, creating a severe disconnect between Coherent's technical valuation and its operational reality.

By examining the fundamentals, investors can spot where the market is mispricing a vital supplier and observe how Coherent is positioning itself to address this industry-wide thermal crisis.

Spotting Value in a Sector-Wide Cool DownThe recent slide in Coherent's stock price feels detached from the underlying business fundamentals. Short interest remains healthy at current levels, indicating that institutional funds are not aggressively betting against Coherent's core operations. Instead, the current sub-$290 price level appears to be a byproduct of sector-wide rotation and general market anxiety.

Institutional accumulation continues to provide a robust floor, driven by sophisticated asset managers who recognize the durability of the current infrastructure cycle. When a ticker boasting a year-to-date climb exceeding 56% experiences a sharp, double-digit contraction in the absence of any fundamental deterioration, the structural narrative demands a closer look.

For market participants monitoring global supply chain pivots, this macro-induced volatility represents a severe disconnect, offering an asymmetrical entry into a vital, highly capitalized supplier precisely as their next-generation technology reaches the evaluation phase.

Breaking the 1,000-Watt Thermal CeilingThe thermal dynamics of modern computing are changing at a blistering pace. High-performance AI clusters operate at extreme temperatures, and the industry is quickly realizing that standard silicon packaging cannot handle the thermal load. Standard materials lack the thermal conductivity needed to quickly remove heat from the core. When this happens, chips warp, system performance degrades, and cooling costs skyrocket.

Coherent recently announced customer sampling of its industry-first 300mm high-thermal-conductivity silicon carbide substrates. Engineered specifically for AI semiconductor partners, this platform directly addresses the thermal bottlenecks throttling modern data centers. Silicon carbide offers incredible mechanical strength and stability, but Coherent's specific engineering delivers up to a 25% improvement in heat spreading compared to current market solutions.

By successfully moving 300mm silicon carbide from internal development to customer evaluation, Coherent transitions from a traditional optical components provider to an indispensable thermal management vendor. When heat removal dictates system reliability, owning the technology that cools the processors means owning a critical piece of the AI value chain.

Bigger Wafers, Better MarginsMoving from a 200mm to a 300mm-diameter platform is a notable technical milestone, but the financial impact should be what catches an investor's attention. Larger wafers drastically increase the usable chip yield per run, improving unit economics. As Coherent fulfills a heavily backlogged order book for AI infrastructure, this pricing power translates directly into margin expansion.

The valuation metrics already reflect this anticipated growth. Coherent is currently trading at a trailing price-to-earnings ratio near 70, which compresses sharply to a forward multiple closer to 37. This expectation of near-term earnings expansion is validated by recent execution. In the fourth quarter earnings report, Coherent delivered earnings per share of $1.74, beating consensus estimates by 31 cents, while driving top-line revenue up about 34% year-over-year.

Scaling manufacturing capacity is notoriously expensive and often forces technology hardware firms to take on heavy debt loads. Coherent has effectively bypassed this risk. Coherent secured an aggregate investment of around $1 billion from Denso OTCMKTS: DNZOY and Mitsubishi Electric OTCMKTS: MIELY, structurally de-risking the aggressive capital expenditures required for the 300mm transition. Denso and Mitsubishi are not passive financiers; they are large consumers of silicon carbide. Their capital injection serves as a heavy validation of Coherent's manufacturing prowess while subsidizing the data center scale-up.

Backed by a debt-to-equity ratio of about 0.29, the balance sheet has ample liquidity to fund the factory expansion without diluting shareholder equity. This setup creates a favorable PEG ratio sitting near 0.8, signaling that the market has not fully priced in the upcoming earnings growth curve.

Regulatory Firewalls and Captive MarketsBeyond the immediate product catalyst, structural shifts in federal policy are creating a wide moat around Coherent's optical and thermal businesses. The Federal Communications Commission is reportedly eyeing a potential ban on Chinese optical transceivers. A regulatory shift of this magnitude fundamentally reroutes domestic data center supply chains.

These components act as the nervous system of the modern data center. Swapping them out for compliant hardware is a capital-intensive necessity for server operators, not a choice. Hyperscalers are being forced to prioritize domestic suppliers to avoid regulatory friction. This creates an artificial supply-demand imbalance, effectively handing a captive-market duopoly to domestic manufacturers like Coherent and its optical communications peers. Industry tracking suggests that order flow is currently outrunning factory capacity, creating a backlog that provides Coherent with highly predictable revenue visibility extending well into the coming fiscal years.

When a business posts a 34% revenue jump, beats earnings estimates, secures a billion dollars in strategic backing, and launches a vital infrastructure product, a double-digit contraction in its stock price rarely aligns with the core business reality. The market is temporarily mispricing the equity due to macroeconomic fears, ignoring the reality that AI demand is outpacing the factories capable of supplying the hardware.

The consensus among analysts remains a Moderate Buy, with average price targets indicating nearly 38% upside from current levels. For those looking to gain exposure to the physical build-out of the artificial intelligence economy, the recent pullback offers a highly compelling entry point.

Coherent has positioned itself as the direct solution to the industry's most pressing engineering problem, making it a foundational piece of tomorrow's technological infrastructure.

The optics complex is splitting in two this morning. Coherent (NYSE:COHR | COHR Price Prediction) is trading down 4.94% and Cisco Systems (NASDAQ:CSCO) is down 8.48% after both reported fiscal fourth-quarter results last night. Yet the pure-play optical vendors that sell into the exact same demand story are green. Ciena (NYSE:CIEN) is up 6.04% and Nokia (NYSE:NOK) is up 3.29%.

Margins and Cash Flow Are the Reason the Reporters Are Red
Both earnings were beats. Coherent posted revenue of $2.05 billion, up 33.74% year over year, and non-GAAP EPS of $1.74 against a $1.612consensus. The Datacenter and Communications segment hit $1.615 billion, up 59% year over year on a pro forma basis. The sore spot is the 8-K cash disclosure: fiscal 2026 operating cash flow of $79.5 million, down 87.45% year over year, against capital expenditures of $1.1029 billion, up 150.18%. Coming into the earnings report, COHR had already rallied 8.35% over the prior week, which included a steep sell-off on Monday and gains last week following reports of potential U.S. bans on Chinese transceiver shipments.

Cisco reported $17.25 billion in revenue, up 17.6% year over year, with $4.0 billion of AI infrastructure orders in the quarter and $9.3 billion for fiscal 2026. FY2027 guidance calls for revenue of $72.2 billion to $73.4 billion and $7.5 billion in AI infrastructure revenue. The issue is margin mix. Non-GAAP gross margin dropped to 66.3% from 68.4% on heavier AI hardware volume and memory cost inflation. CEO Chuck Robbins called it “a very strong close to fiscal 2026, marking another record year for Cisco,” but the stock is trading as if expectations were priced for perfection.

Why Ciena and Nokia Are Rallying Off the Same Data
The read-through is that data center interconnect and coherent optical transport demand is inflecting hard. On Lumentum’s conference call earlier this week CEO Michael Hurlston said:

“Expanding, inferencing and training applications are driving full rate connectivity between data centers, while political and regulatory constraints favor smaller, more modular builds. These 2 factors among others are substantially increasing the demand for our pump laser solutions. To put this in perspective, for one major hyperscaler, the network capacity connecting just 2 AI data center sites could double the total global backbone capacity they built over the entirety of the last decade. To support the growth and scale across deployments, we have secured multiple long-term customer agreements that helped offset our planned capital expenditures. We continue to expect a fourfold increase in our pump laser shipments over the next several quarters to meet this escalating demand.”

That quote is music to the ears of companies like Nokia and Ciena. In addition, Coherent CEO James Anderson said on last night’s call that “The demand just continues to go up for anything DCI or scale across related.”Cisco said their Acacia optics unit had another $1 billion quarter that was “very strong.”

That is exactly the addressable market Ciena and Nokia sell into. Ciena’s most recent quarter showed 39.51% revenue growth with cloud provider revenue at 46% of total, growing 70% year over year. Nokia’s Q2 AI and Cloud revenue more than doubled year over year with $3.2 billion in AI and Cloud order intake. Nokia trades as a US-listed ADR.

Another catalyst for this group appears to be Wall Street commentary. Last night JPMorgan issued a note taht the strongest parts of Cisco’s earnings had positive read-through for Nokia as the company reported surprisingly strong telecom orders. That’s also positive read-through for Ciena itself.

Jim Cramer has a clear message for investors chasing photonics exposure: skip speculative small caps and own companies already delivering results. During a recent Mad Money Lightning Round, Cramer passed on Poet Technologies without an opinion, directing investors instead to his preferred names in the space: Lumentum Holdings (NASDAQ:LITE | LITE Price Prediction) and Coherent (NYSE:COHR).

This past spring, Cramer pointed to both stocks as the right way to play data center optical infrastructure, noting that “both of them are getting $2 billion investment from NVIDIA, but Lumentum’s been the better performer.” The thesis is straightforward: if the AI infrastructure cycle continues, own companies with order books, margins, and backlog to prove it.

Lumentum: The Faster-Growing Engine
Lumentum’s most recent quarter makes the bull case concrete. Q2 FY2026 revenue reached $665.5 million, up 66% year-over-year, with non-GAAP EPS of $1.67 beating the $1.4085 consensus by 19%. Non-GAAP operating margin expanded 1,730 basis points year-over-year to 25%. The stock has responded accordingly: Shares are up more than 143% year to date and nearly 685% over the past year.

Two growth engines are early in their ramp. The optical circuit switch (OCS) backlog exceeds $400 million, and the company recently received an incremental multi-hundred-million-dollar co-packaged optics (CPO) order deliverable in the first half of calendar 2027. CEO Michael Hurlston captured the forward picture: “Our forward guidance calls for over 85 percent year-over-year revenue growth, yet we are only at the starting line for two substantial opportunities: optical circuit switches and co-packaged optics.”

Q3 FY2026 guidance calls for revenue of $780 million to $830 million and non-GAAP operating margin of 30% to 31%. The company’s SEC filing confirms these figures directly from management.

Coherent: Scale and Diversification
Coherent operates at larger scale with a broader product portfolio for AI infrastructure. Q2 FY2026 revenue came in at $1.686 billion, up 18% year-over-year, beating estimates by 3%, with non-GAAP EPS of $1.29 beating the $1.2061 consensus by roughly 7%. The datacenter and communications segment, which now represents roughly 72% of total revenue, grew 34% year-over-year to $1.208 billion.

The company sharpened focus by completing the sale of its Aerospace and Defense business and using proceeds for $400 million in debt repayment. CEO Jim Anderson outlined the trajectory: “We expect continued strong growth in the second-half of fiscal 2026 and throughout fiscal 2027 based on strong datacenter and communications demand and our continued production capacity expansion.”

Coherent’s year-to-date performance reflects this momentum. Shares are up 84.38% year to date and nearly 242% over the past year. Q3 FY2026 guidance targets revenue of $1.70 billion to $1.84 billion, with the company recognized as an NVIDIA Ecosystem Innovation Partner for co-packaged optics.

Why Proven Beats Speculative
The photonics theme is real. Retail investors on Reddit have been asking the same question in recent weeks, with an r/stocks thread titled “Is photonics just getting started? $LITE and $COHR” drawing sustained engagement. The difference between Lumentum and Coherent versus early-stage photonics names comes down to execution. Both Lumentum and Coherent generate revenue at scale, expand margins quarter over quarter, and sit on multi-hundred-million-dollar order pipelines tied directly to hyperscaler AI infrastructure spending. Cramer’s preference for names with demonstrated financial momentum over unproven stories reflects a straightforward risk calculus the numbers support.

Coherent’s Q4 Growth Hinges on AI Demand, Capacity Expansion and Margin GainsFiscal fourth-quarter revenues are likely to have benefited from exceptional demand in Datacenter & Communications, led by 800G and rapidly ramping 1.6T transceivers, OCS systems and initial scale-out CPO revenues. Capacity expansion is another key catalyst, with Coherent accelerating the doubling of internal indium phosphide output and ramping 6-inch production. Improving industrial demand could provide additional support. On the bottom line, higher volumes, a richer 1.6T mix and 6-inch manufacturing efficiencies should aid gross margins. However, sequentially higher capital investment and operating expenses may temper profitability gains.

COHR Stock Experiencing GrowthCoherent shares have gained a massive 195% over the past year and 12% in the past month. This performance clearly indicates consistent growth in the stock.

Based on forward 12-month Price/Earnings, COHR is currently trading at 42.32X, way above the industry’s 21.7X. If we look at the forward 12-month Price/Sales ratio, the company’s shares are currently trading at 7.27X forward sales, well above the industry’s 2.8X.

Coherent is a Hold Ahead of Q4 EarningsCoherent’s strong demand backdrop, expanding AI-driven Datacenter & Communications business, and accelerating capacity investments support its long-term growth prospects. Improving product mix and manufacturing efficiencies could also aid profitability as production ramps. However, the stock’s sharp appreciation and premium valuation suggest that much of the optimism surrounding these growth drivers may already be reflected in the share price. With expectations elevated heading into the fiscal fourth-quarter report, any disappointment in execution, margins or the pace of capacity conversion could pressure the stock. Investors may therefore prefer to maintain existing positions and await greater clarity after earnings, making COHR a Hold.

Peer ViewAmong U.S.-listed peers, Lumentum Holdings (LITE - Free Report) and IPG Photonics (IPGP - Free Report) offer useful comparisons for investors evaluating Coherent. Like Coherent, both LITE and IPGP operate in optical components and photonics markets that benefit from increasing demand for high-speed data communications and advanced laser technologies. However, Coherent currently stands apart because of its unusually strong AI infrastructure exposure, record backlog extending into 2028, long-term supply agreements through 2030, and a significantly strengthened balance sheet following NVIDIA's strategic investment. These factors have helped improve earnings visibility and differentiate Coherent's growth profile within the photonics industry.

Shares of Coherent COHR surged on Tuesday after a report said the Trump administration is drafting restrictions on imports of new Chinese data center components, a move that could benefit US optical networking suppliers as cloud providers seek alternative vendors.

Coherent shares climbed as much as 12% in trading following the Reuters report.

Fellow optical networking company Lumentum gained more than 5%, while Applied Optoelectronics also rallied. Meanwhile, Amazon.com shares fell more than 1.7% in trading.

According to Reuters, the Federal Communications Commission (FCC) is preparing a proposal that would prohibit imports of new Chinese optical transceivers, components that enable high-speed data transmission across fiber-optic cables inside AI data centers.

The report said the proposal could be published later this year, although it has not been finalized and could still be modified or withdrawn.

The proposed restrictions are aimed at protecting US AI infrastructure from potential cybersecurity risks.

A ban on new Chinese optical transceivers could force American cloud providers, including Amazon Web Services, to source more equipment from domestic manufacturers such as Coherent and Lumentum.

Reuters reported that the proposed restrictions would likely target Zhongji Innolight, one of the world's largest optical transceiver manufacturers. The company was added to the Pentagon's list of alleged Chinese military-backed companies in June.

The report said the restrictions are intended to reduce the risk of Chinese-made networking hardware being used to steal data, install malware or disrupt operations at US AI data centers.

China's embassy in Washington criticized the proposed measures and urged the United States to stop targeting Chinese companies.

"China will take all necessary measures in response to any action that causes material harm to its interests," it added.

Coherent has already strengthened its position in the AI infrastructure supply chain through partnerships with Nvidia.

The chipmaker signed multi-year agreements with both Coherent and Lumentum in March, including billions of dollars in procurement commitments and a $2 billion investment in each company to secure production capacity for next-generation co-packaged optics technology.

The agreements position both companies as strategic suppliers for the growing AI data center market, where demand for high-speed optical networking equipment continues to increase.

Supply chain implications remain in focusAccording to Counterpoint Research, Zhongji Innolight controls approximately 27% of the global data center transceiver market.

Reuters reported that Coherent and Lumentum offer competing technologies but currently lack the manufacturing scale to fully replace Chinese suppliers. Innolight also generates about 90% of its revenue outside China.

The FCC has previously introduced similar restrictions targeting Chinese drones, routers, robots and power inverters through its Covered List framework.

The report said that the agency is considering a similar approach for optical transceivers by banning imports of new Chinese models while exempting many non-Chinese suppliers.

While the proposal remains under review, investors responded positively to the possibility that tighter restrictions on Chinese networking equipment could increase demand for US-based optical component manufacturers, sending Coherent shares sharply higher.

Key Takeaways COHR raised its outlook and highlighted record backlog visibility extending through 2028.COHR expects fiscal 2027 growth to outpace fiscal 2026 while ramping its 6-inch indium phosphide platform.COHR continues to outperform key optical networking peers with stronger AI infrastructure exposure. Coherent (COHR - Free Report) appears to offer a more compelling investment opportunity following its recent post-earnings correction. The stock retreated despite the company delivering a strong quarterly performance, raising its outlook and highlighting record backlog visibility extending through 2028.

Management also reaffirmed that fiscal 2027 growth is expected to exceed fiscal 2026 levels while continuing to ramp production of its 6-inch indium phosphide platform, a critical technology supporting next-generation AI networking. The sharp decline came after an extraordinary rally rather than any deterioration in business fundamentals, reflecting a reset in investor expectations. COHR remains up an impressive 218% over the past year, even after declining 19% over the past month.

                                                           Image Source: Zacks Investment Research

Although the stock trades at a forward 12-month price-to-earnings ratio of 36.29X, above the industry average of 20.89X, the recent correction has made the valuation more reasonable relative to its long-term growth prospects.

                                                                  Image Source: Zacks Investment Research

Supporting this view, the Zacks Consensus Estimate for 2026 earnings is pegged at $5.47, indicating 55% year over year growth. The consensus mark for 2026 revenues stands at 7.06 billion, suggesting 21.5% year over year growth.

Coherent Continues to Outperform Key PeersCompared with optical networking peers Lumentum (LITE - Free Report) and Fabrinet (FN - Free Report) , Coherent continues to benefit from stronger exposure to AI infrastructure investments and increasing demand for high-speed optical connectivity. While LITE and FN are well-positioned to capitalize on data center upgrades, Coherent has strengthened its competitive standing through manufacturing expansion, long-term customer commitments and improved backlog visibility.

The company is also demonstrating an ability to translate robust demand into profitable growth while maintaining confidence in future expansion. As AI infrastructure spending continues to accelerate, Lumentum, Fabrinet and Coherent are all expected to benefit. However, Coherent currently combines superior growth visibility, expanding production capacity and a more attractive post-correction valuation, making it stand out among its optical networking peers.

COHR currently sports a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks #1 Rank stocks here.

Key Takeaways Coherent's order book surge pushed backlog to record levels and drove $290M CapEx.Customer orders stretch into 2028, while long-term agreements extend revenue visibility to 2030.NVIDIA's $2B investment lifted COHR's cash balance to $3B in Q3. Coherent Corp. (COHR - Free Report) is witnessing a step function increase in its order book rather than the usual increment in cyclical hardware orders. This drastic upsurge in demand pushed Coherent’s backlog into record levels, compelling the company to spend $290 million in CapEx, more than doubling growth from the year-ago quarter.

                                                                  Image Source: Zacks Investment Research

This lofty asset-heavy expansion is de-risked by customer orders stretching into 2028 and Long-Term Agreements extending to 2030. A heightened revenue visibility guards Coherent from short-term demand contraction that creates a menace within the hardware manufacturing sector.

Coherent’s tactical approach to raise customers’ vested interest effectively lowered the risks associated with aggressive capacity expansion. The company guided customers toward entering agreements that mandate multi-year demand commitments and capital investments, insulating supply.

NVIDIA’s $2-billion equity investment provided an extra padding to Coherent’s cash balance, raising it to $3 billion in the third quarter of fiscal 2026 from $1.5 billion in the previous quarter. This strategic partnership stands as a witness to testify to COHR’s tech as the bottleneck for AI infrastructure in the long run.

Coherent jumped on this operational momentum to deleverage its balance sheet. The company took the major step of wiping out $162 million in debt payments in a single quarter, which reduced its leverage ratio to 0.5X in the third quarter of fiscal 2026 from the previous quarter’s 1.7X. The company’s elite financial profile is dependent on its ability to maximize cash cushions and cut down fixed interest burden.

The combination of long-term commitments stretching into 2030, robust liquidity and a deleveraged balance sheet provides Coherent the bedrock to transform its cyclical hardware business into a predictable revenue-generating machinery. Coherent’s commercial predictability paves the path to future growth while maintaining the strength to sail through macroeconomic setbacks.

COHR’s Price Performance, Valuation & EstimatesCoherent’s stock has rallied a whopping 427.6% in a year, beating the industry’s 10.2% growth. COHR surpassed its competitors, IPG Photonics (IPGP - Free Report) and Novanta (NOVT - Free Report) , which have gained 75% and 26.8%, respectively, in the same period.
