Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
NVA was founded by veterinarian Dr. Stanley Creighton and began acquiring its first 22 hospitals with Willis Stein & Partners backing. The model preserved local practice autonomy and veterinary-led decision-making. At this scale, competitive impact was minimal, labor practices were practice-specific, and financial extraction was limited to the founding PE partnership.
Summit Partners acquired NVA and professionalized the acquisition pipeline, recruiting a dedicated business development team. NVA grew from 96 to 240+ hospitals and tripled EBITDA over seven years. The company remained veterinarian-led under Greg Hartmann, but the acquisition pace and production-driven management philosophy intensified under PE growth mandates.
Ares Management acquired NVA for ~$800 million and expanded the company internationally, launching VetPartners in Australia (2016), entering Canada, and adding pet resorts. NVA grew from 240 to 700+ locations. Non-compete clauses became standard for acquired veterinarians. OMERS took a minority stake in 2017. The MSO structure to circumvent state CPVM laws became institutionalized.
JAB Holding Company acquired NVA for $7.7 billion and merged it with Compassion-First, creating the largest private veterinary network globally. Employees reported an immediate culture shift toward revenue-focused management. The Ryuk ransomware attack crippled 400 clinics. The FTC required its first set of divestitures (3 clinics) for the Compassion-First/NVA merger, signaling regulatory attention to veterinary consolidation.
JAB's $2.75 billion in SAGE and Ethos acquisitions triggered a second FTC enforcement action requiring 8 more clinic divestitures and imposing a 10-year prior approval requirement for specialty/emergency acquisitions. Three rounds of mass layoffs gutted NVA's support center. NVA tripled in size under JAB, with production pressure and standardized diagnostic protocols accelerating across acquired clinics. Veterinary costs surged 8-9% annually.
NVA split from Ethos to prepare separate IPOs as JAB's exit strategy. Congressional investigation by Senators Warren and Blumenthal demanded financial data on pricing, wages, and noncompete practices. Veterinary costs rose 32% from 2020-2024 with NVA-owned clinics leading the trend. The FTC's noncompete ban was blocked by federal courts, preserving NVA's restrictive employment clauses that suppress competition from departing veterinarians.
Alternatives
Privately owned, non-corporate vets are the most direct escape from PE-driven price extraction in the veterinary market. They set their own prices, are not bound by corporate upsell protocols, and often provide more continuity of care. Ask directly whether a practice is independently owned or affiliated with NVA, VCA, Banfield, Thrive, or BluePearl networks. The American Veterinary Medical Association's vet finder can help locate practices in your area.
Accredited veterinary schools (Cornell, UC Davis, Tufts, Colorado State, etc.) operate teaching hospitals with veterinary school faculty supervising students. Prices are typically 20-40% lower than private practices, and the diagnostic thoroughness is often higher. Best suited for complex cases or specialist care; usually not practical for routine wellness visits unless you're near a veterinary school.

NVA announced the sale of its VetPartners business in Australia, New Zealand, and Singapore to Swedish PE firm EQT for approximately AUD 1.4 billion (USD 900 million). The sale of 267 practices divested NVA's international operations to generate cash for JAB ahead of U.S. IPO plans.
