Citi told clients in a note Tuesday that it expects semiconductor stocks to rebound after a summer slump, arguing that a heavy conference schedule and resilient data center demand should support the sector. The bank noted the Philadelphia Semiconductor Index fell 18% over the summer as the group ran into high expectations and a modest deceleration in earnings momentum. Even so, Citi looks for a recovery heading into its Global TMT conference, where it expects positive commentary led by AMD, MRVL, LITE, ALAB, and semi caps. Data center demand remains strong, accounting for 34% of the industry's total addressable market, while autos and industrials, at 21%, continue to recover. Demand from PCs and handsets, which make up 42% of the market, is said to remain weak amid memory cost inflation and supply constraints. The bank turned more bullish on central processing units after recent earnings and the Hot Chips conference, lifting its CPU market forecast to $237 billion by 2030 from $29 billion in 2025, a 52% compound annual growth rate, above forecasts from AMD, Arm and Nvidia. Citi expects AMD to be the key beneficiary of what it called a "CPU renaissance," with Intel a secondary winner. Furthermore, Citi raised its outlook for wafer fabrication equipment spending, citing a stronger hyperscaler capital expenditure model, now seeing a 2028 bull case approaching $300 billion, with base-case spending of $257 billion, up from $250 billion previously.

The global optical transceiver market is being reshaped by AI and high-speed networking, with NVIDIA committing $2 billion to Lumentum and Marvell planning to acquire Celestial AI for up to $5.5 billion. These investments highlight the surging demand for high-bandwidth connectivity from hyperscale AI infrastructures. Domestic manufacturing capacity is expanding in the U.S., and government policies are expediting procurement for AI-integrated optical communications. Lumentum Holdings closed at $914.76, up 2.2%, while Wiwynn rose 9.9% to NT$7,800.00 and Ruijie Networks fell 6.3% to CN¥119.37. In other moves, Microsoft expanded its collaboration with HUMAIN to offer an AI productivity bundle targeting one million users in the Middle East and Africa.

Lumentum Holdings has received a multibillion-dollar AI-driven investment that includes a sizeable stake from NVIDIA, and announced plans for a new U.S.-based photonics fabrication facility focused on 800 Gbps and 1.6 Tbps optical interconnects for data infrastructure. The investment supports Lumentum's role as a supplier of core networking components for AI workloads, aligning with growing demand from hyperscale data center operators and governments. However, it does not resolve key risks such as dependence on a small set of hyperscale customers and pressure from lower-margin cloud modules. Investors will watch for concrete metrics like capacity additions, product mix, and margins in upcoming earnings and guidance updates across 2026 and 2027, particularly progress on 800G and 1.6T interconnect volumes and utilization of the new U.S. facility.

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.

Networking is replacing raw computing power as the main constraint on artificial intelligence performance as AI systems grow larger and more complex, according to Citi analysts following the second day of the Hot Chips conference. The shift creates a particularly positive outlook for Nvidia, Broadcom, Arista Networks, Lumentum, Coherent, Marvell Technology, and Astera Labs, Citi said. The analysts noted that the first wave of AI infrastructure development focused heavily on faster GPUs, larger accelerators, and greater training capacity, but as AI systems expand toward trillions of parameters, larger context windows, and autonomous agent workloads, efficiently moving data between chips, servers, racks, and data centers is becoming a bigger bottleneck. Citi said presentations from Nvidia, Broadcom, Meta Platforms, Alphabet's Google, Samsung, and other companies pointed toward the same trend, with the future AI winner being the company that can move data most efficiently throughout the entire system. Memory is also increasingly part of the networking challenge, as technologies from Samsung, XCENA, and Cerebras aim to keep data closer to processing, reducing communication overhead. Citi highlighted Nvidia's concept of future data centers as "AI factories," designed around data flows rather than servers, which could shift more AI infrastructure value toward companies optimizing the entire data movement stack.

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).

AXT, Inc. is expanding its supply agreements with major customers, improving visibility into future InP shipments and potentially supporting revenue growth. The company's second-quarter 2026 results showed backlog exceeding $100 million, with coverage extending into 2027 through both backlog and long-term supply agreements. AXT's agreements with Casela and Coherent further reinforce this pipeline: Casela committed to approximately $25.4 million of InP wafer purchases for 2027, with at least 80% of the committed quantity subject to purchase, while Coherent agreed to a three-year development and supply arrangement for 6-inch InP wafers, backed by a $22.3 million prepayment. In July, AXT signed a long-term agreement with Lumentum covering minimum annual InP capacity commitments through December 2031, with an initial $43.5 million deposit and a second $43.5 million deposit to be determined during 2028. These agreements are particularly meaningful because customer demand already exceeds AXT's available InP capacity, while the company is expanding production and developing higher-value 6-inch substrates. According to the Zacks Consensus Estimate, AXTI's revenues are projected to reach $217.6 million in 2026. The expansion of supply agreements could further enhance revenue visibility, as it will boost production capacity and convert contracted demand into actual shipments.

Lumentum Holdings Inc reported fiscal fourth-quarter results above Wall Street expectations and issued first-quarter guidance that exceeded analyst forecasts, driven by strong artificial intelligence-related demand for optical connectivity in data centers. Adjusted earnings per share came in at $3.23, beating the consensus estimate of $2.95, while revenue reached $1.01 billion, ahead of the $984.57 million forecast and up 109% from $480.7 million a year earlier. For the first quarter of fiscal 2027, the company guided for revenue between $1.225 billion and $1.275 billion, with a midpoint of $1.25 billion above the $1.16 billion consensus, and adjusted earnings per share of $4.05 to $4.35, whose midpoint of $4.20 exceeded the $3.63 estimate. Adjusted gross margin expanded to 50.4% from 37.8% a year ago, and adjusted operating margin rose to 36.6% from 15.0%. Raymond James analysts maintained an Outperform rating and raised their price target to $1,036 from $1,014. Shares rose around 8% in premarket trading, extending a year-to-date gain of more than 122%.

Coherent shares climbed 5.7% in premarket trading to $347.37 after rival Lumentum Holdings reported fiscal fourth-quarter revenue and adjusted earnings above Wall Street forecasts and issued stronger-than-expected first-quarter sales guidance, reinforcing expectations of robust demand for optical networking equipment. The positive read-through encouraged investors ahead of Coherent's own fiscal 2026 fourth-quarter results due after the NYSE close, with analysts forecasting revenue of approximately $1.98 billion and non-GAAP earnings per share of $1.43, representing roughly 93% year-on-year growth. Raymond James lifted its price target on Coherent to $435 from $371 while maintaining a Strong Buy rating, and a Federal Communications Commission proposal to prohibit imports of Chinese optical transceivers could provide a significant advantage to domestic manufacturers, with Coherent positioned as a potential major beneficiary. The company's broad photonics portfolio and global manufacturing operations provide exposure to expanding demand for AI infrastructure, supported by initiatives including Nvidia's $2 billion investment aimed at expanding Coherent's U.S. manufacturing capacity. Attention now turns to Coherent's fiscal fourth-quarter report and its strategic relationship with Nvidia, with the results likely to determine whether the latest share-price recovery can maintain its momentum.
