Senseonics Holdings (AMEX:SENS) saw its stock price plummet 10.42% in after-hours trading on Thursday, following the release of its first-quarter earnings report. Despite meeting analyst expectations on earnings per share and beating revenue estimates, investors appeared to react negatively to the company's financial performance.

The continuous glucose monitoring systems developer reported a quarterly loss of $0.02 per share, in line with analyst consensus estimates. This represents a 33.33% improvement from the $0.03 per share loss reported in the same quarter last year. Senseonics also posted quarterly sales of $6.26 million, surpassing the analyst consensus estimate of $5.56 million by 12.50%. The revenue figure marks a 23.97% increase compared to the $5.05 million reported in the same period last year.

Despite the revenue beat, Senseonics' financial results revealed some concerns. The company reported a gross profit of $1.505 million for the quarter, while operating income stood at a negative $13.488 million. Net income for the period was also in the red at $14.259 million. Looking ahead, Senseonics provided a full-year revenue outlook of $34-38 million, which may have fallen short of investor expectations and contributed to the sharp after-hours decline.
