CommVault Systems (NASDAQ: CVLT) saw its stock price plummet 5.25% in pre-market trading on Tuesday after the data management software company released its second-quarter fiscal 2026 financial results and provided disappointing full-year revenue guidance.

For Q2, CommVault reported revenue of $276 million, slightly beating analyst estimates of $273.3 million. The company also announced earnings before interest and taxes (EBIT) of $12 million and adjusted EBIT of $51 million. While these results were largely in line with expectations, investors seemed more focused on CommVault's forward-looking projections.

The primary driver of the stock decline appears to be CommVault's full-year revenue outlook. The company forecasted fiscal 2026 revenue in the range of $1,161 million to $1,165 million, which fell short of Wall Street's expectations. This tepid revenue guidance suggests CommVault may be facing headwinds in its core markets, potentially due to increased competition or slower enterprise IT spending. As a result, investors are reassessing the company's growth prospects, leading to the significant pre-market sell-off.
