Credo Acquires DustPhotonics for $750 Million, Bringing Silicon Photonics In-House as AI Data Center Optical Demand Surges
Credo Technology pays $750M cash plus stock for Israeli silicon photonics firm DustPhotonics, targeting $500M in combined optical revenue by fiscal 2027.
Overview
Credo Technology Group has agreed to acquire DustPhotonics, an Israeli developer of silicon photonics integrated circuits, for $750 million in cash and approximately 920,000 shares of Credo common stock, according to a press release published by the company. The deal includes contingent consideration of up to 3.21 million additional shares tied to financial milestones, and is expected to close in the second quarter of 2026 pending regulatory approval.
The acquisition creates a vertically integrated connectivity platform spanning serializer/deserializer (SerDes) intellectual property, digital signal processing, silicon photonics, and system integration, positioning Credo to compete across both electrical and optical interconnects for AI data center infrastructure.
What We Know
DustPhotonics, founded in 2017 and headquartered in Modi’in, Israel, operates as a fabless semiconductor company with roughly 70 employees, according to Credo’s announcement. The company has developed a portfolio of Silicon Photonics Photonic Integrated Circuits (SiPho PICs) spanning 400G, 800G, and 1.6T data rates, with a product roadmap extending to 3.2T. Its chips are already deployed in optical transceivers at leading hyperscale AI clusters and are designed for both Near Port Optics (NPO) and Co-Packaged Optics (CPO) applications.
The company was co-founded by optical communications veterans including Ben Rubovitch, the former CEO of Mellanox Technologies, and is chaired by Avigdor Willenz, who previously led Habana Labs to its acquisition by Intel and Annapurna Labs to its sale to Amazon Web Services, as Calcalist reported.
DustPhotonics’ product line includes the Tamar200, described as the industry’s first merchant 1.6T-2xFR4 photonic integrated circuit supporting two 800G-FR4 transmit channels, according to a DustPhotonics product announcement. The chips use proprietary low-loss Mach-Zehnder Modulator technology and eliminate the need for thermoelectric coolers, reducing power consumption.
Credo CEO William Brennan called the deal “a defining step in Credo’s strategy to lead across the full spectrum of AI connectivity,” and said the company expects its combined optical portfolio to generate more than $500 million in revenue in fiscal 2027, according to the press release. DustPhotonics CEO Ronnen Lovinger said that “joining Credo is the natural next step” and that Credo “brings the SerDes IP, the hyperscaler relationships, and the operational scale to turn that vision into reality.”
Credo shares rose approximately 10 percent in after-hours trading following the announcement.
What We Don’t Know
The announcement does not specify which hyperscale customers are currently using DustPhotonics components, nor does it detail the financial milestones tied to the contingent share consideration. Credo has not disclosed how DustPhotonics’ roughly 70 employees will be integrated into the existing organization, or whether the Israeli operation will continue as a standalone research center.
The SiPho PIC market is projected to reach $6 billion by 2030, according to estimates from LightCounting cited in Credo’s announcement, but whether Credo can capture a significant share of that market against larger incumbents remains an open question. The deal’s accretive impact on non-GAAP earnings per share in fiscal 2027, while projected, depends on execution and integration speed.
Analysis
The acquisition reflects a broader wave of consolidation in the silicon photonics supply chain as AI infrastructure buildout drives insatiable demand for optical interconnects. As previously reported, TSMC has begun mass production of its COUPE silicon photonics platform, signaling that the transition from copper to optical interconnects inside AI data centers is accelerating from prototype to production scale.
By bringing silicon photonics in-house, Credo follows a strategy of vertical integration that reduces dependence on external PIC suppliers at a time when component shortages could become a bottleneck. DustPhotonics’ pedigree is notable: its leadership team includes veterans of Mellanox (now part of NVIDIA) and founders with a track record of building and selling Israeli chip companies to Silicon Valley’s largest buyers, as Calcalist noted.
The $750 million price tag, while substantial for a roughly 70-person company, is consistent with the premium valuations that silicon photonics assets now command in an industry where optical bandwidth is becoming as strategic as compute power itself.
