Shares of Trupanion Inc. (TRUP), a leading provider of medical insurance for pets, plunged over 5% in the pre-market session on Wednesday after the company reported disappointing third-quarter earnings results.

For the quarter ended September 30, Trupanion reported adjusted earnings per share of $0.03, missing the consensus estimate of -$0.06 per share. While the company's revenue rose 14.6% year-over-year to $327.46 million, it fell short of analysts' expectations of $321.79 million.

Despite the earnings miss, Trupanion's net income for the quarter came in at $1.43 million, reflecting an improvement from the prior-year period. However, investors appeared to focus on the weaker-than-expected financial performance, leading to the sharp decline in the company's stock price.
