IDEXX Laboratories (IDXX - Free Report) has shown remarkable momentum so far this year, climbing 52.9%. The stock has comfortably surpassed the industry’s 12.9% fall and the S&P 500 Composite’s 13.8% gain.

Carrying a Zacks Rank #3 (Hold) at present, the pet healthcare innovator’s robust strategic execution is highlighted by new business gains, high customer retention levels and solid net price realization. Its software solutions are facilitating growth by enhancing clinic workflows and promoting greater utilization of diagnostics.

Headquartered in Westbrook, ME, IDEXX Laboratories offers products and services mainly for the companion animal veterinary, livestock and poultry, water testing and dairy sectors. Through its Companion Animal Group (“CAG”) Diagnostics segment, the company provides diagnostic capabilities that meet veterinarians’ diverse needs through a variety of modalities, including in-clinic diagnostic solutions and outside reference laboratory services. IDEXX has a sales footprint across the United States and in key regions globally, including Africa, Asia Pacific, Canada, Europe and Latin America.

What’s Behind IDXX Stock’s Price Surge?

The rally in the company’s share price can be linked to the strong momentum in the CAG Diagnostics business. Over the past few quarters, CAG Diagnostics’ recurring revenue growth has consistently remained above sector growth levels. The company’s long-term success in CAG recurring diagnostic products and services depends upon growing volumes of existing customers by increasing their utilization of existing and new test offerings, acquiring new customers, maintaining high customer loyalty and retention, and realizing modest annual price increases.

In the second quarter of 2025, worldwide CAG Diagnostics recurring revenues increased 7.5% organically, supported by an average net price improvement of approximately 4% and benefits from CAG Diagnostics instrument revenues increasing 62% on an organic basis, aided by inVue Dx placements.  Internationally, growth was supported by new business expansion, which was reflected in a double-digit year-over-year improvement in the global premium instrument installed base. IDEXX also generated substantial revenues and margins from the sale of consumables used in IDEXX VetLab instruments.

In addition, the company’s cloud-based products, including ezyVet, Animana, Cornerstone, IDEXX NEO, DVMAX PIMS (practice information management systems) and Web PACS (picture archiving and communication system imaging software), continue to be in high demand. The newly introduced Vello software solution experienced continued momentum with double-digit sequential growth in active users. Its software solutions are driving innovation-driven growth by improving clinic workflows and supporting greater utilization of diagnostics. IDEXX is also building on the robust features of its customer engagement solution by integrating Greenline Pet, a digital platform acquired earlier in 2024.

Through strategic investments, the company continues to strengthen its future growth prospects by delivering high-touch commercial engagement in the fastest-growing regions while maintaining strong business performance. IDEXX’s expanded global commercial capability is yielding strong results overseas, with a notable 11% organic rise in international CAG Diagnostics’ recurring revenues in the second quarter of 2025.
