Shares of Clearfield (NASDAQ: CLFD) fell sharply in after-hours trading on Thursday, February 6th following the company's fiscal first-quarter 2025 earnings release. Clearfield reported revenue of $35.5 million, narrowly missing analyst estimates of $35.8 million. More significantly, the fiber optic equipment maker posted a net loss of $0.13 per share, much wider than the expected $0.31 per share loss.

The disappointing results weighed on Clearfield's stock, sending it plunging 8.24% in after-hours trading. The sell-off reflects investor concerns over the company's weaker-than-anticipated top-line performance and larger-than-expected net loss for the quarter.

While Clearfield saw a modest 4% year-over-year increase in revenue, driven by growth in its connected homes products, higher costs and expenses contributed to the wider net loss. The company cited lower gross margins due to inventory charges, as well as elevated operating expenses, as key factors behind the larger net loss for the quarter.
