Wolfspeed, a leading player in the silicon carbide (SiC) revolution, has consistently highlighted the promising future of both electric vehicles (EVs) and industrial and energy (I&E) applications. However, a careful examination of their recent Q3 2024 earnings transcript <a href="https://seekingalpha.com/article/4618746-wolfspeed-inc-wolf-q3-2024-earnings-call-transcript" alt="Q3 2024 Transcript">[1]</a> reveals a nuanced shift in their strategy, potentially overlooked by many analysts. Despite persistent assertions of robust long-term demand, Wolfspeed appears to be discreetly adjusting its production capacity towards EVs, even if it means sacrificing short-term profitability. Does this indicate a shrewd move to capitalize on immediate prospects or a sign that the company is hedging its bets on the enduring potential of the I&E sector?

The transcript presents a contrasting picture of Wolfspeed's two primary markets. While Mohawk Valley, their flagship 200mm SiC fab dedicated almost exclusively to EV customers, is experiencing rapid growth, the I&E market is facing a "challenging" climate. This downturn, attributed to inventory accumulations mainly in Asia, has prompted Wolfspeed to implement a significant production realignment. Durham, their 150mm fab traditionally serving the I&E market, is now witnessing a substantial portion of its capacity repurposed for EV manufacturing.

While portrayed as a temporary measure, this shift raises several thought-provoking questions. Firstly, it exposes an unexpected fragility in Wolfspeed's widely acclaimed vertically integrated model. The company has long underscored the strategic edge of governing the entire SiC supply chain, from raw materials to end products. However, this susceptibility to fluctuations in specific segments implies that even a vertically integrated model can be vulnerable to external pressures.

Secondly, the production pivot prompts inquiries regarding the extent and duration of the I&E market's slump. Wolfspeed anticipates this sluggishness to linger until at least the latter half of calendar year 2025. Though they insist that I&E products constitute a "substantial and important part of their product portfolio," the choice to redirect capacity for such an extended period suggests a more profound apprehension. Could Wolfspeed possess insights, possibly derived from their materials clients, indicating a more drawn-out decline in I&E demand than currently reflected in the broader market?

The financial ramifications of this strategic adjustment are also noteworthy. The transition to larger, more intricate automotive-grade dies in Durham is cited as a primary contributor to the projected short-term gross margin challenges. While Wolfspeed contends that the "same underlying production will not yield comparable revenue or gross margin outcomes" for EVs compared to I&E, this raises concerns.

Let's delve into the numbers. In Q4 2024, Wolfspeed projects materials revenue to hold steady at roughly $90 million to $95 million. Nevertheless, Durham device revenue is expected to fall considerably to about $55 million to $70 million. This signifies a year-over-year drop of almost 50%, underscoring the significant effect of the production shift. Even with a generous estimate of 40% gross margin for materials and 25% for Durham devices (taking into account the shift towards more lucrative EVs), the combined gross profit from these sectors would be $51.5 million at the midpoint.

Considering the total revenue forecast of $185 million to $215 million and Mohawk Valley's contribution of $40 million to $50 million, this suggests a gross margin of just 1.6% to 12.6% for Mohawk Valley alone. This is substantially lower than the margins presently attained in Durham, even with the inefficiencies of the EV production transition. Although Wolfspeed emphasizes that Mohawk Valley's unit costs are "very, very positive," this disparity is perplexing. Could this signal that the 200mm fab has not yet realized the cost effectiveness initially projected?

It is crucial to recognize that Wolfspeed continues to report robust design-in and design-win momentum, surpassing $7 billion in design-ins for fiscal 2024 alone. However, the bulk of these design-ins, along with a record $2.9 billion in design-wins, are heavily concentrated in the EV sector. While this mirrors the current strength of the EV market, it also amplifies the uncertainty about Wolfspeed's long-term dedication to the I&E domain.

Revenue Breakdown

Here's a table summarizing Wolfspeed's Q4 2024 revenue projections from different segments:

Is Wolfspeed subtly pivoting from its "silicon carbide for all things" philosophy and evolving into a more EV-focused enterprise? The transcript certainly hints at this possibility. The company's emphasis on immediate EV demand, coupled with a cautious outlook on I&E market resurgence and a postponement of greenfield expansion initiatives, suggests a strategic transition is underway.

This silent shift, while inconspicuous, could carry significant implications for Wolfspeed's trajectory. Should the I&E market rebound quicker than projected, the company might find itself trailing competitors who have sustained a more balanced approach. Conversely, if the EV market falters or faces heightened competition, a heavily concentrated strategy could leave Wolfspeed vulnerable. Only time will reveal whether this understated pivot proves to be a stroke of brilliance or a calculated risk.

"Fun Fact: Silicon carbide, often referred to as "carborundum," was initially discovered in 1891 during an attempt to create artificial diamonds. It's a testament to how scientific exploration can lead to unexpected discoveries with far-reaching applications, such as in today's EVs and power electronics."
