A Look at IDEXX Laboratories's Valuation After Raising Annual Revenue Guidance on Strong Pet and Water Business Trends

Kshitija Bhandaru

If you’re keeping an eye on IDEXX Laboratories (IDXX), this week’s move might give you pause for thought. The company has raised its annual revenue outlook, thanks to steady growth in both its pet healthcare segment and its water testing operations. This kind of upbeat guidance is usually welcomed by investors, as it signals confidence from management and hints at real business traction underneath the headlines.

The timing of IDEXX’s guidance update aligns with a broader period of momentum for the stock. Shares are up roughly 57% year to date and have gained 34% over the past year. Even the last quarter alone saw a 22% surge, showing that the market has responded consistently to the company’s execution and growth trends. While recent days saw a modest daily bump amid this positive news, the bigger picture is a story of long-term outperformance supported by real operational growth.

But with such an impressive rally already in the books, the big question is whether IDEXX Laboratories is still attractively valued or if the market has already factored in all this growth potential. Is there more room to run, or could buyers be arriving late to the party?

Most Popular Narrative: 7.5% Undervalued

The most widely followed narrative sees IDEXX Laboratories as moderately undervalued, suggesting its future earnings and business model have yet to be fully reflected in the current share price.

“High customer retention and growing installed base of premium instruments provide IDEXX with stable, high-margin recurring revenue streams, positioning the company to compound earnings growth over time as industry consolidation and elevated care standards continue.”

Craving the blueprint behind this bullish price target? The valuation is driven by a scenario with steady profit expansion and a premium multiple that puts IDEXX in elite company. What ambitious projections and future expectations are driving the story? The full narrative breaks down all the surprising assumptions behind the fair value calculation.
