The Zacks Consensus Estimate for Fabrinet's earnings is $4.19 per share, suggesting 43.49% growth, and the stock holds a Zacks Rank #2 (Buy).

A new BCC Research pulse report reveals that AI-driven demand for 400G, 800G, and 1.6T connectivity is accelerating photonics investment, highlighted by NVIDIA's $2 billion investment in Lumentum and Marvell's planned acquisition of Celestial AI for up to $5.5 billion. The report, titled "AI Impact on Optical Transceiver Market," examines how AI workload expansion, strategic corporate investment, and government digital infrastructure mandates are reshaping procurement priorities and technology roadmaps. Hyperscale AI infrastructure is the primary demand engine, with optimized transceiver-enabled architectures reducing GPU idle time from over 30% to below 15%. Domestic manufacturing capacity is scaling rapidly, with Applied Optoelectronics announcing a $150 million expansion in Texas and Lumentum investing in a new U.S. fabrication facility. Government policies across the U.S., EU, China, Japan, and India are accelerating procurement timelines, while emerging technologies like co-packaged optics and Celestial AI's Photonic Fabric, targeting 16 Tbps solutions, are redefining the performance frontier. Coherent Corp. flagged revenue growth exceeding 22% year-over-year and earnings per share growth of 2.8x, driven by AI data center exposure.

Coherent Corp. reported fiscal fourth-quarter revenues of $2.05 billion, up 34% year over year and 13% sequentially, driven by its Datacenter & Communications segment, which surged 59% to $1.62 billion and now accounts for nearly 79% of total revenue. GAAP gross margin expanded 277 basis points to 38.5%, and adjusted operating margin rose 381 basis points to 21.8%. Management guided first-quarter fiscal 2027 revenue to $2.2-$2.4 billion and adjusted earnings per share of $1.85-$2.05. However, Industrial revenue fell 16% to $431 million, increasing reliance on datacenter spending. Among peers, Lumentum Holdings posted fiscal fourth-quarter revenue of $1.01 billion, more than doubling year over year, while Applied Optoelectronics reported second-quarter revenue of $191.9 million, up 86%. Coherent's stock has gained 226.5% over the past year, trading at a forward P/E of 31.55X versus the industry's 21.17X, and carries a Zacks Rank #2 (Buy).

Applied Optoelectronics is positioning its laser manufacturing and automated U.S.-based production as key differentiators as data-center customers expand AI infrastructure. CFO Stefan Murry said the company's primary limitation is manufacturing capacity rather than technology, and it is shipping small quantities of high-power lasers for customer evaluation. Transceiver capacity is targeted to increase from more than 200,000 units per month to 650,000 by year-end, with larger Houston production contributions expected in 2027–2028. The company expects near-term gross margins around 32%–33%, while targeting approximately 40% by the end of 2027. It is evaluating co-packaged optics opportunities with five companies, but elevated capital spending and limited capacity may restrict how quickly it can serve new customers.

AI infrastructure stocks edged higher in pre-market trading on Monday after Anthropic's second quarter revenue surged to $11.5B, nearly two-and-a-half times the first quarter's $4.7B figure.

Lumentum shares surged 15% to $942 in midday trading Wednesday after the optical components maker reported fiscal Q4 2026 revenue of $1.01 billion, more than doubling year over year and topping the $988.6 million consensus, with non-GAAP EPS of $3.23 versus the $2.99 consensus and non-GAAP gross margin of 50.4%. The company guided fiscal Q1 2027 revenue of $1.225 billion to $1.275 billion and EPS of $4.05 to $4.35, with CEO Michael Hurlston saying it will hit its $1.25 billion quarterly revenue target more than a quarter early, pump-laser shipments up more than 80% year over year and effectively sold out, and the 1.6T transceiver ramp accelerating. The rally spilled across the AI optics complex, with Coherent up 9% to $358, Corning up 5% to $167, Applied Optoelectronics up 3% to $139, Ciena up 13%, and the iShares Semiconductor ETF trading at $551, while Super Micro Computer jumped 16%, CoreWeave soared 20%, and Nebius Group surged 27% on AI infrastructure prints that reinforced hyperscaler capex momentum. JPMorgan raised its Lumentum price target to $1,280 from $1,165 with an Overweight rating, Mizuho lifted its target to $1,140 from $1,100 with an Outperform rating, and Morgan Stanley raised its target to $1,000 from $900 with an Equal Weight rating, while Bank of America cut its target to $1,000 from $1,100 with a Neutral rating even after raising CY2027 and CY2028 EPS estimates by 19% each, reflecting a de-rating across shortage-area names.

Applied Optoelectronics and Coherent each surged 13% on Friday after Applied Optoelectronics reported second-quarter revenue nearly doubled to $191.9 million and swung to a non-GAAP net income of $5.5 million from a loss of $8.8 million a year earlier. Lumentum added 8% as the rally extended across optical communications stocks, with the iShares Semiconductor ETF up 2% and the NASDAQ 100 up 0.94%. A weaker-than-expected July jobs report reduced expectations for a Federal Reserve rate hike in September, providing an additional tailwind for growth-oriented technology shares. Applied Optoelectronics' results reinforced optimism around demand for high-speed optical transceivers driven by AI data-center investment, while Coherent and Lumentum moved higher without company-specific catalysts.

The Federal Communications Commission is drafting a rule to ban imports of new Chinese optical transceivers, a move that could reshape the AI supply chain given China controls more than 50% of the global market. Applied Optoelectronics, a Texas-based manufacturer, reported fiscal first-quarter revenue of $151.14 million, up 51.4% year over year, and has expanded capacity to nearly 100,000 units of 800G transceivers per month. Coherent, which received a $2 billion investment from Nvidia, posted fiscal third-quarter revenue of $1.81 billion, with its datacenter and communications segment up 40.6%. Lumentum saw revenue surge 90.1% to $808.4 million in its fiscal third quarter, while contract manufacturer Fabrinet reported record revenue of $1.21 billion. Credo Technology, which offers copper-based alternatives, more than tripled its full-year revenue to $1.34 billion. All five companies have posted four consecutive earnings beats and guided for sequential growth, with the FCC aiming to publish the rule this year.

Counterpoint Research warned that Chinese optical module makers control roughly two-thirds of global transceiver supply and no Western alternative can absorb that volume within one to two years, casting doubt on a proposed U.S. import ban. The FCC is drafting a ban on new Chinese optical transceiver models, with officials hoping to publish the measure before year-end, Reuters reported. Analyst Neil Shah cautioned that Coherent and Lumentum lack the cleanroom capacity, automated packaging infrastructure, and yield scale required to absorb Innolight and Eoptolink's volume within a 12-to-24-month horizon, which could cause cost escalation and delayed AI cluster deployments for hyperscalers like AWS, Microsoft, Meta, and Google. Chinese module makers as a group supply approximately 60% of global optical datacom transceiver revenue, with Zhongji Innolight alone holding roughly 27% of the market and generating 62% of its revenue from the United States in the first quarter of 2026. The proposed ban follows Innolight's $6.8 billion Hong Kong listing and its addition to the Pentagon's list of alleged Chinese military-backed firms, while U.S.-listed optical networking stocks surged on Tuesday with Coherent rising 11%, Applied Optoelectronics gaining 18%, and Lumentum climbing 7%.

Shares of Applied Optoelectronics surged 17% to $129.34 on Tuesday after Reuters reported that the Trump administration and the FCC are drafting a ban on U.S. imports of new Chinese optical transceivers used in AI data centers. Coherent climbed 11% to $319.80 and Lumentum gained 6% to $829.42, extending a multi-day rally for the optical group. The reported draft rule, which officials aim to finalize this year, would benefit domestic and non-Chinese suppliers while pressuring Chinese makers such as Zhongji Innolight, which holds a 27% global transceiver share. Applied Optoelectronics, which has guided second-quarter 2026 revenue to $180 million to $198 million and is targeting over $1 billion in full-year 2026 sales, is up 216% year to date. The iShares Semiconductor ETF added 5%, trailing the pure-play optics names because optical transceiver makers are a small slice of the broad semiconductor fund.

Applied Optoelectronics shares jumped over 13% after the company completed its first volume shipment of 800G transceivers to a large hyperscale customer and guided full-year 2026 revenue above $1 billion, more than double 2025's total. First-quarter datacenter revenue more than doubled year-over-year to $81.4 million, driving total revenue up 51.4% to $151.14 million. Management guided second-quarter revenue to $180 million to $198 million and expects significantly larger sequential growth starting in the third quarter as additional capacity comes online. The company has nearly doubled its Houston-area manufacturing footprint and exited the quarter with capacity of nearly 100,000 800G units per month, positioning it as a premier U.S. producer of AI-focused datacenter optics. With $449.38 million in cash and shareholders' equity up 257.9% to $1.11 billion, AAOI is funding its ramp without dilution or heavy debt.

Applied Optoelectronics has begun constructing two adjacent properties in Pearland, Texas, adding nearly 400,000 square feet of manufacturing capacity. The expansion aims to increase production of its 800G and 1.6T optical transceivers, which are a main component of AI infrastructures enabling fast, long-distance data transmission over fiber optics. CFO and Chief Strategy Officer Dr. Stefan Murry said the new facilities will support the company's long-term growth strategy and strengthen its position as a key supplier to the AI and cloud infrastructure markets.

Applied Optoelectronics rallied after reporting a healthy quarter and winning major new orders from large hyperscale customers, according to the Carillon Eagle Small Cap Growth Fund's first-quarter 2026 investor letter. The company supplies fiber-optic networking products increasingly used in AI data centers. It also made progress on a new US-based facility expected to increase capacity to serve other hyperscale customers next year. The stock closed at $146.97 per share on June 24, 2026, with a one-month return of -13.05% and a 52-week gain of 429.24%, giving it a market capitalization of $11.79 billion. Hedge fund ownership rose to 55 portfolios at quarter-end from 36 in the prior quarter.

Applied Optoelectronics is working with Mediacom to accelerate DOCSIS 4.0 network upgrades and expand fiber and coax infrastructure across the cable operator's footprint. Mediacom plans to upgrade its network to serve about 1 million homes by the end of 2026 using distributed access architecture, DOCSIS 4.0, fiber expansion, and whole-home Wi-Fi technology. Applied Optoelectronics is the primary vendor for these upgrades, supplying 1.8GHz smart amplifiers and related software designed to increase capacity, improve signal quality, and lower operating costs. The project highlights Applied Optoelectronics' role in advanced optical and hybrid fiber-coax networking hardware, which addresses the same bandwidth challenges driving AI infrastructure spending.

Applied Optoelectronics, Inc. received a bullish thesis from TradersPro, citing its leverage to artificial intelligence and hyperscale cloud infrastructure expansion.
