Shares of materials and photonics company Coherent (NYSE:COHR) rose 8.4% after announcing advancements in its silicon carbide (SiC) technology for high-voltage AI datacenter and industrial power applications, leading to a positive analyst rating. This surge highlights the acute pain point gripping the sector: exploding energy demands from AI workloads that threaten to overwhelm power grids and inflate operational costs. Our analysis at L-Impact Solutions reveals how Coherent’s thick epitaxy breakthrough for 10kV devices positions the firm to capture massive opportunities while offering practical paths forward that you can implement today.
The announcement on April 9, 2026, enables power devices up to 10 kilovolts with superior efficiency and power density. It directly tackles the inefficiencies plaguing traditional silicon-based systems in high-voltage environments. Recent data shows Coherent’s Q1 fiscal 2026 revenue hit $1.58 billion, up 17% year-over-year, fueled by AI-driven demand in datacenters and communications.
Global AI datacenter power consumption is skyrocketing, with U.S. facilities alone consuming 183 terawatt-hours in 2024, or about 4% of national electricity. Projections indicate this will surge 133% to 426 terawatt-hours by 2030. Worldwide, data centers are on track to reach 945 terawatt-hours by 2030 under IEA base-case scenarios, doubling from recent levels and driven largely by AI servers.
Silicon carbide technology delivers game-changing advantages here. SiC devices achieve over 98% efficiency in power conversion, slashing losses compared to silicon while enabling higher switching frequencies and smaller components. Coherent’s advancements build on its leadership in 200mm and emerging 300mm SiC wafers, supported by strategic partnerships worth over $1 billion from players like Denso and Mitsubishi Electric.
As authoritative business analysts, we see this as more than a product update. It signals Coherent’s pivot toward the high-voltage power segment, where AI datacenters require robust uninterruptible power supplies and advanced distribution systems. The stock’s 347% gain over the past year underscores investor conviction, with 15 analysts recently revising earnings estimates upward.
Yet the broader market context amplifies the stakes. The global SiC power semiconductor market stood at approximately $2.23 billion in 2025 and is projected to reach $11.29 billion by 2033 at a 22.5% CAGR. Coherent’s innovation aligns perfectly with industrial electrification and renewable integration trends, creating a multi-billion-dollar addressable opportunity.
This case study demonstrates clear momentum. Coherent’s technology directly mitigates the energy bottlenecks that could otherwise stall AI growth. Forward-looking leaders like you can leverage these insights to evaluate partnerships and infrastructure upgrades that deliver both immediate savings and long-term competitive edges.
L-Impact Solutions Critique: Exposing Risks and Gaps in Coherent’s SiC Momentum
At L-Impact Solutions, we applaud Coherent’s 8.4% stock surge and SiC advancements, but a hard-nosed critique reveals significant vulnerabilities that could undermine the gains. The pain point of runaway AI power demand remains only partially addressed, as scalability challenges and intense competition threaten execution. Without swift action on these gaps, the upside risks evaporating into stalled adoption and margin pressure.
First, execution risks loom large despite the positive analyst ratings. Coherent’s Q1 2026 gross margin reached 36.6% GAAP, but ramping thick epitaxy production for 10kV devices demands massive capital and supply-chain discipline. Recent TTM revenue of $6.29 billion shows strength, yet over-reliance on AI datacenter bookings—now at book-to-bill ratios exceeding 4x—exposes the firm to cyclical slowdowns if hyperscaler spending moderates.
Competition intensifies the pressure. Established SiC leaders like Wolfspeed and onsemi already command share in high-voltage applications, while broader market entrants accelerate 200mm and 300mm wafer transitions. Coherent’s valuation appears stretched, with some models suggesting overvaluation relative to fundamentals even after the surge, as fair-value analyses indicate limited near-term upside buffer.
Supply-chain and geopolitical gaps further compound risks. Silicon carbide substrate costs remain volatile amid raw-material constraints, and U.S.-China tensions could disrupt epitaxy equipment flows. Industrial power applications beyond datacenters, while promising, face slower adoption curves due to legacy infrastructure inertia, limiting near-term revenue diversification.
From our consultant lens, the announcement hints at efficiency gains but overlooks full lifecycle costs for end-users. Higher upfront pricing for premium SiC modules could deter smaller industrial players, creating a two-tier market where only hyperscalers benefit immediately. Environmental scrutiny adds another layer, as datacenter electricity demand could drive 8% average U.S. bill increases by 2030 per Carnegie Mellon estimates.
These critiques are not deterrents but calls to vigilance. L-Impact Solutions views Coherent’s position as strong yet fragile without proactive risk mitigation. Businesses ignoring these gaps risk stranded assets in a power-hungry AI era, where efficiency alone cannot offset systemic vulnerabilities in grid capacity and technology access.

Solutions: Practical Strategies You Can Deploy to Harness SiC Technology
You face the AI power crisis head-on, and L-Impact Solutions delivers actionable solutions tailored to your operations. Start by auditing your current high-voltage infrastructure to identify where Coherent-style 10kV SiC devices can replace legacy silicon components. This step typically yields 15-20% efficiency gains in power conversion, directly cutting energy bills that are projected to rise sharply as U.S. datacenters consume 426 terawatt-hours by 2030.
Next, forge strategic partnerships with Coherent or authorized integrators for pilot deployments in your AI datacenters. You gain access to thick epitaxy modules that boost power density and reduce cooling demands, freeing capital previously tied to oversized UPS systems. Our clients report payback periods under 18 months when combining SiC with existing renewable microgrids, aligning with the global SiC market’s 22.5% CAGR through 2033.
You should also invest in workforce upskilling programs focused on SiC system integration. Train your engineering teams on high-frequency switching protocols to maximize the 98%-plus efficiency these devices deliver. Financially, this approach lowers total cost of ownership while positioning your firm to capture incentives from federal clean-energy grants targeting datacenter electrification.
Consider portfolio diversification by allocating 10-15% of your capex budget to SiC-enabled industrial applications. You expand beyond pure AI into manufacturing and energy storage, where Coherent’s advancements support multi-kilovolt power distribution.
