CoreWeave shares slide nearly 8% after Bernstein criticism and heavy interest costs

what happened

Shares of GPU cloud provider CoreWeave slid 7.9% to $60.60 in early New York trading on October 15, according to GuruFocus. Investors reacted to a bearish note from Bernstein analyst Madison Rezaei, who kept an Underperform rating, as Yahoo Finance reported. The larger concern, however, runs deeper than one analyst's verdict: the company needs its growing computing business to generate enough profit to service its debt.

In its August 11 earnings release, CoreWeave reported quarterly revenue of $2.575 billion, an operating loss of $49 million and net interest expense of $640 million. That interest burden equaled about 24.9% of revenue and rose roughly 140% from $267 million a year earlier. Because interest is booked below operating income, the $49 million loss does not include that charge.

GuruFocus also cites a GF Score of 8 out of 100, which it treats as a weak signal rather than a standalone investment conclusion. Next, the company must convert customer contracts into delivered capacity, recognized revenue and cash left after operating costs. The outlet suggests watching utilization, financing expenses and funding needs side by side.

why it matters

For markets, the episode shows how quickly interest costs can outweigh revenue growth at capital-intensive AI infrastructure firms. Fast expansion draws attention, but turning it into earnings that can cover debt is the harder test.
