    Wolfspeed’s Mohawk Valley Silicon Carbide Fab Reached 20% Wafer Start Utilization

    4 Min Read

    Wolfspeed, Inc. provided an update on key milestones and an operational update.

    Wolfspeed’s Mohawk Valley silicon carbide fab has reached 20% wafer start utilization, a critical step in the Company’s efforts to meet the growing demand for silicon carbide power devices. Additionally, Wolfspeed’s Building 10 Materials facility has achieved its 200mm wafer production target to support approximately 25% wafer start utilization at the Mohawk Valley fab by the end of calendar year 2024. Wolfspeed plans to update the market on its next utilization milestone for Mohawk Valley during its fiscal Q4 2024 earnings call in August.

    The Mohawk Valley fab has also achieved LEED (Leadership in Energy and Environmental Design) Silver certification, a distinction from the world’s most widely used green building framework and rating system. The LEED Silver certification highlights Wolfspeed’s enduring commitment to going beyond compliance, promoting environmental health and industry leading sustainability.

    This state-of-the-art Mohawk Valley facility is the world’s first purpose-built, fully automated 200mm silicon carbide fab, and when combined with Wolfspeed’s market-leading 200mm materials production, solidifies Wolfspeed’s competitive position as the only fully vertically integrated 200mm silicon carbide manufacturer at scale.

    Additionally, Wolfspeed’s John Palmour Manufacturing Center (“the JP”) in Siler City, NC, which will be the world’s largest, most advanced silicon carbide materials facility upon completion, has installed and recently activated initial furnaces less than one year after vertical construction commenced. As a result, the facility is on schedule to achieve crystal qualification by early August 2024. This meaningful progress reinforces the Company’s confidence that it is well-positioned to ramp the JP in line with its target to deliver wafers from the facility to Mohawk Valley by the summer of 2025.

    Wolfspeed also announced that it experienced an equipment incident at its Durham 150mm device fab that resulted in a temporary capacity reduction while the incident was being remediated. Production has been resumed and the Company expects that the Durham 150mm device fab’s capacity utilization can return to previously targeted levels by August. As a result of the production disruption, the Company does not expect an impact on fourth quarter revenue, but does expect to have an underutilization impact and incur other costs in the fourth quarter as described below.

    “Having reached our 20% utilization target at Mohawk Valley, we are well-positioned to continue executing our 200mm vertical integration strategy ahead of other market participants,” said Gregg Lowe, president and CEO of Wolfspeed. “Further, recent advancements at the JP put Wolfspeed well on track to achieve our facility targets and significantly expand our materials capacity, driving meaningful progress towards our strategic goals. We quickly identified and resolved an equipment incident at our Durham 150mm device fab, and we continue to focus on execution as we move with urgency to continue this first-of-its-kind ramp.”

    Business Outlook

    Based on the Durham 150mm device fab equipment incident, Wolfspeed is updating its fiscal fourth quarter 2024 guidance as follows, and providing a preliminary outlook on fiscal first quarter 2025 revenue and non-GAAP gross margin:

    • Targeted fiscal fourth quarter revenue from continuing operations is unchanged at $185 million to $215 million; and a potential negative impact to fiscal first quarter 2025 revenue of approximately $20 million.
    • Targeted fourth quarter GAAP gross margins in the range of (4%) to 4% and non-GAAP gross margins in the range of 0% to 8%, due to an underutilization impact realized in the fourth quarter and other fourth quarter costs related to the equipment incident.  The Company also expects fiscal first quarter 2025 non-GAAP gross margins in a similar range due to underutilization it will realize in the period.
    • Fourth quarter GAAP net loss from continuing operations is targeted at $204 million to $182 million, or $1.61 to $1.44 per diluted share. Non-GAAP net loss from continuing operations is targeted to be in a range of $122 million to $105 million, or $0.96 to $0.83 per diluted share. Targeted non-GAAP net loss from continuing operations excludes $77 million to $82 million of estimated expenses, net of tax, primarily related to stock-based compensation expense, amortization of discount and debt issuance costs, net of capitalized interest, project, transformation and transaction costs and loss on Wafer Supply Agreement.
