Cotiviti Appoints John Hallock as Chief Corporate Affairs Officer to Advance Next Phase of Growth

New leadership role reflects Cotiviti's accelerating expansion and long-term vision

SALT LAKE CITY, UT, April 24, 2026 - Cotiviti, a leader in enterprise healthcare software and data-driven technology solutions, today announced the appointment of John Hallock as Chief Corporate Affairs Officer. Reporting directly to Chief Executive Officer Ric Sinclair, Hallock will lead corporate communications, brand development and marketing strategy, and investor relations.

Hallock joins Cotiviti at a pivotal moment as the company accelerates into its next phase of growth, expanding beyond healthcare enterprise solutions into a system-level platform that operates as a foundational structural layer across the healthcare ecosystem. Increasingly, Cotiviti is serving as a central hub that powers coordination, transparency, financial accuracy, and performance at scale. Across payers and providers, value-based care organizations, and partners, the company is enabling more consistent decision-making, simplifying administrative processing, improving financial outcomes, and bringing greater alignment to a complex and fragmented market.

"Cotiviti sits at the center of some of the most critical financial and data flows in healthcare," said Sinclair. "As the industry moves toward greater standardization, interoperability, and alignment, accelerated by advances in data infrastructure and AI, we see a clear opportunity to establish a structural utility layer that governs financial accuracy and decision-making across the ecosystem. At its core, this is about reducing administrative waste, lowering costs across the system, and improving the quality of care. John's experience building category-defining companies at key inflection points will be instrumental as we advance this next phase of growth."

Hallock brings more than two decades of experience shaping market-defining companies at transformative junctures, with a track record of building and scaling category narratives that reposition businesses and expand market perception. He led communications and investor positioning for Livongo's emergence as a category defining company, including its IPO, as well as the athenahealth IPO, and has held senior leadership roles supporting the growth and positioning of healthcare platforms across the ecosystem.

Most recently, Hallock served in a senior leadership role at Smarter Technologies, where he was part of the founding leadership team and helped shape the company's creation, including its initial platform build and strategic acquisitions. He played a key role in defining the enterprise narrative and market positioning during a period of rapid expansion and integration.

"I'm incredibly excited to join Cotiviti and partner with such a strong leadership team at a pivotal moment for both the company and the broader healthcare industry," said Hallock. "Healthcare does not have a data problem; it has an alignment and structural problem. Cotiviti is uniquely positioned to serve as a consistent and enabling layer across the ecosystem, improving financial accuracy while driving greater coordination at scale, particularly through the combination of technology, data, and deep domain expertise."

In his new role, Hallock will oversee all aspects of corporate affairs and work closely with the leadership team to support strategic growth initiatives and further strengthen Cotiviti's market position.
