## Summary

Coherent Corp (COHR) reported $5.2B revenue in FY2024, up 3% YoY. Leader in optical components and fiber optics for AI data centers and telecom. HQ: Saxonburg, PA. Market cap ~$15B.

## Company Overview

Coherent Corp. is a global leader in compound semiconductors, optical components, lasers, and photonic products for data center interconnects, telecom networks, industrial applications, and consumer electronics, headquartered in Saxonburg, Pennsylvania. Formed through the 2022 merger of II-VI Incorporated and Coherent Corp (formerly JDSU/Viavi optical assets), the combined company reported revenues of $5.2B in fiscal year 2024 (ending June 2024), with data center networking emerging as the primary growth driver.

Coherent's business spans three segments: Networking (transceiver modules and photonic integrated circuits for data center and telecom, ~40% of revenue), Materials (silicon carbide wafers, compound semiconductor substrates, ~35%), and Lasers (industrial and scientific lasers, ~25%). The Networking segment has seen explosive growth as AI data center builders deploy 800G and 1.6T optical transceivers to handle AI workload traffic. Coherent is one of three major suppliers of high-speed optical transceivers alongside Lumentum and Inphi (Marvell). Its 800G QSFP-DD transceivers are deployed in NVIDIA AI clusters and hyperscale data centers globally.

Coherent's silicon carbide (SiC) substrate business — selling SiC wafers to semiconductor manufacturers including Wolfspeed, STMicro, and Onsemi — benefits from EV adoption driving SiC power device demand. The company is also a major supplier of vertical cavity surface-emitting lasers (VCSELs) used in iPhone Face ID and LiDAR systems. Coherent trades on NYSE (COHR) and has been working to reduce leverage from the II-VI merger and improve profitability.

## Frequently Asked Questions

### What is Coherent's annual revenue?
Coherent Corp. reported $5.2B in revenue for fiscal year 2024 (ending June 2024), up approximately 3% year-over-year, with strong growth in data center optical transceivers partially offset by softer industrial laser demand.

### What does Coherent Corp make?
Coherent makes optical transceivers for data centers and telecom, compound semiconductor wafers (SiC, InP, GaAs), industrial and scientific lasers, and consumer optoelectronics (VCSELs for smartphone sensors).

### What is Coherent's stock ticker?
Coherent Corp. trades on NYSE under ticker COHR.

### How does Coherent benefit from AI?
AI data centers require massive bandwidth between servers and switches. Coherent's 800G and 1.6T optical transceivers are the primary connectivity solution for this, making Coherent a key beneficiary of the AI networking buildout.

### Who are Coherent's main competitors?
In optical transceivers, Coherent competes with Lumentum, Inphi (now Marvell), Applied Optoelectronics (AAOI), and Acacia (Cisco). In compound semiconductors, it competes with Wolfspeed, MACOM, and II-VI legacy assets.

### What is Coherent Corp's role in AI data center networking?
Coherent Corp supplies 400G and 800G optical transceivers that connect GPUs, switches, and servers inside AI training clusters — the photonic building blocks of hyperscale data center networks at companies like Microsoft, Google, and Amazon. As AI workloads require enormous bandwidth between GPU nodes, the demand for high-speed optical interconnects has become a primary growth driver for Coherent, with data center networking now representing the largest and fastest-growing segment of the company's revenue. Coherent competes with Lumentum, II-VI (now merged with Coherent), Inphi, and Finisar in supplying transceivers for the AI infrastructure buildout.

### How was Coherent Corp formed and what are its main business segments?
The current Coherent Corp was formed through the 2022 merger of II-VI Incorporated (a compound semiconductor and optical components manufacturer) and the legacy Coherent Corp (known for industrial and scientific lasers), creating a vertically integrated photonics company with three segments: Networking (optical transceivers, photonic integrated circuits for data center and telecom), Materials (silicon carbide wafers, compound semiconductor substrates for power electronics and RF), and Lasers (industrial lasers for material processing). The merger created a company with the broadest portfolio of compound semiconductor and photonic technologies in the industry.

### What is Coherent Corp's silicon carbide business?
Coherent Corp is one of the leading producers of silicon carbide (SiC) wafers and epitaxial substrates used in power electronics for electric vehicles, EV charging infrastructure, and industrial power conversion — markets that require semiconductors capable of handling high voltages and temperatures where silicon-based devices fail. SiC wafers from Coherent's Materials segment are used by major power device manufacturers to make the MOSFETs and Schottky diodes that control power flow in EV drivetrains. The SiC business provides Coherent with a diversification against the cyclicality of the optical networking business.
