CoreWeave (CRWV.US) shares plunged nearly 15% at one point! Bond yields approaching 15% spark financing concerns; Bernstein warns that the high-debt growth model is unsustainable.

AI cloud computing service provider CoreWeave (CRWV.US) shares plunged nearly 15% at one point on Wednesday, as investor concerns over its high-debt expansion model continued to intensify. In a research report released on October 15, Bernstein pointed out that the market's concern is not insufficient AI computing demand, but the financing costs CoreWeave must bear to continue expanding to meet that demand. As the yield on some of the company's unsecured bonds approaches 15%, its business model of relying on external financing to drive growth is facing increasingly severe tests. Bernstein maintained its "Underperform" rating on CoreWeave with a target price of $74. The stock closed at $65.78 on Wednesday. Although the target price is about 12% above the current share price, Bernstein emphasized that its long-term concerns are mainly focused on the economic sustainability of the company's business model and its future competitive position in the AI infrastructure market. Bond Yields Approach 15%, Financing Costs Become Market Focus Bernstein noted that CoreWeave's unsecured bonds due in 2032 with a 9.625% coupon rate now have a yield to maturity of about 14.8%. This level is typically associated with debt pricing for financially distressed companies, indicating that bond investors are demanding higher risk compensation. Although rising bond market yields will not immediately change the interest expense on the company's existing fixed-rate debt, they will directly affect the cost of future new financing. For a company highly dependent on debt financing to build AI data centers, this change is particularly important. CoreWeave's business model requires substantial upfront investment in GPUs, data center construction, and related infrastructure before customers pay. Because the company lacks other businesses that can consistently generate large cash flows, rapid growth actually further widens the financing gap. Data shows that in the second quarter of this year, CoreWeave's operating cash flow was only $679 million, while adjusted capital expenditures reached $9.4 billion, leaving a gap of more than $8.7 billion between the two. At the same time, the company's second-quarter net interest expense reached $640 million, accounting for about one-quarter of quarterly revenue. Bernstein believes this means that even if CoreWeave can continue to secure customer orders, it must constantly rely on external funding to support business expansion, and rising financing costs could significantly weaken the profitability of future projects. Debt Scale Continues to Swell, Concentrated Repayment Pressure After 2030 Another challenge facing CoreWeave is its growing debt burden. As of the end of June this year, the company's debt scale was about $35 billion, in addition to about $16.5 billion in lease liabilities, bringing the total to more than $50 billion. The latest debt breakdown attached to Bernstein's research report further shows that CoreWeave's total outstanding debt has reached about $40.95 billion, corresponding to a financing capacity of about $57.21 billion, with a weighted effective interest rate of about 8%, and estimated annual interest expense of about $3.26 billion. Among this, some debt financing costs have reached double digits. For example, a delayed draw term loan due in 2028 has an effective interest rate of about 15%, and several equipment financing and term loans have effective interest rates ranging from 9% to 12%. From the perspective of debt maturity structure, CoreWeave's short-term repayment pressure is relatively limited, but 2030 to 2032 will see a clear peak in concentrated debt maturities. Bernstein data shows that the company has about $531 million, $1.276 billion, $2.576 billion, and $2.665 billion of debt maturing from 2026 to 2029, respectively. However, debt maturing in 2030, 2031, and 2032 will reach about $11.149 billion, $9.389 billion, and $10.366 billion, respectively, totaling more than $30 billion over the three years. This means CoreWeave not only needs to continue raising funds to support new project construction, but must also consider the cost and feasibility of large-scale debt refinancing in the future. Bernstein pointed out that while expanding financing scale can certainly drive revenue growth, it also means more creditors will have priority claims ahead of shareholders, potentially further weakening the economic returns ultimately available to common shareholders. Changes in Customer Contract Structure May Intensify Financing Pressure In addition to financing costs and debt scale, Bernstein also paid special attention to the quality of CoreWeave's future customer contracts. The firm noted that if the company's new business gradually shifts toward shorter-term contracts, or increasingly comes from non-investment-grade credit rating customers, the contract protection obtained by lenders will correspondingly decline. In this case, even if CoreWeave can continue to sign new AI computing service contracts, creditors may still demand higher interest rates or stricter financing terms. In other words, order growth does not necessarily mean shareholder value grows in tandem. Bernstein emphasized that CoreWeave needs not only customers willing to buy computing power, but also lenders willing to provide funds, and the financing terms must be reasonable enough to leave attractive investment returns for shareholders. It is worth noting that recent market rumors suggest CoreWeave is seeking to attract funding support from insurance companies. Bernstein believes this further highlights the importance of financing issues in the company's investment logic and reflects management's urgent need to seek more and lower-cost capital. Meanwhile, research firm Gartner recently released a report once again raising concerns about the business models of emerging AI cloud service providers. Tesla, Inc. CEO Musk subsequently responded to related discussions on social media with "yikes," which also drew market attention. However, Bernstein believes that the financing dependence problem facing CoreWeave is not something that emerged recently. Wednesday's sharp stock decline more reflects the market beginning to reassess long-existing financial risks, rather than the company disclosing major new negative operational news. Strong AI Demand Does Not Resolve Long-Term Competitive Pressure Despite its cautious stance on CoreWeave, Bernstein does not deny the strong demand in the current AI computing market. The firm expects CoreWeave to still have the opportunity to sign more large customer contracts in the future, and related news could also drive short-term stock gains. According to Bernstein's forecasts, CoreWeave's revenue this year will reach $12.622 billion, further growing to $23.552 billion in 2027. During the same period, the company's adjusted EBITDA is expected to increase from $6.826 billion in 2026 to $14.974 billion in 2027. However, Bernstein expects CoreWeave's adjusted loss per share this year to reach $4.56, widening further to $4.77 in 2027. The firm believes that CoreWeave's core long-term challenge is that, as global data center supply gradually increases after 2028, whether the company can continue to secure large hyperscale cloud customer contracts at the current scale remains highly uncertain. At the same time, major cloud service providers such as Amazon.com, Inc. (AMZN.US), Microsoft Corporation (MSFT.US), and Alphabet Inc. Class C (GOOG.US, GOOGL.US) continue to expand their own AI infrastructure and may compete more aggressively for enterprise AI customers. Bernstein questions whether CoreWeave's existing software platform is sufficient to constitute a long-term competitive moat, especially when large cloud service providers have stronger financial resources, broader customer bases, and stronger infrastructure integration capabilities. The firm believes that even if overall AI demand continues to grow, these structural competitive issues will not automatically disappear; they may only further delay the time when the risks truly materialize. Of course, if large cloud service providers' self-built data center commissioning progress is delayed, or power supply continues to constrain new data center construction, CoreWeave may still maintain some pricing power through its existing computing resources. If its specialized software platform can generate stable customer demand, it may also improve its long-term competitive prospects. But Bernstein emphasized that investors need to distinguish between business scale growth and shareholder economic returns. In the firm's view, whether CoreWeave can create long-term value in the future depends not only on how much AI customers are willing to pay for computing power, but more importantly on how much it costs the company to raise the funds needed to build that computing power. As unsecured bond yields approach 15%, financing costs are becoming the key variable determining whether CoreWeave's high-growth model can be sustained.
