Framingham, MA (November 5, 2026) – Definitive Healthcare Corp. ("Definitive Healthcare" or the "Company") (Nasdaq: DH), an industry leader in healthcare market data and analytics, today announced financial results for the quarter ended September 30, 2026.

• Revenue was $54.7 million, a decrease of 9% from $60.0 million in Q3 2025.³

"Since joining Definitive, I've been focused on listening to our customers and our employees," said Clay Ritchey, CEO of Definitive Healthcare. "What I've heard confirms my belief in the strength of our position in the market, and it has also shown me where we can execute better. This quarter's results demonstrate the underlying health of the business and a solid foundation to build upon."

Recent Business and Operating Highlights:

Customer Wins

In the third quarter, Definitive Healthcare continued to win new logos and expansion opportunities across all end-markets, by providing the data, insights and integrations that drive their critical business use cases. Customer wins for the quarter included:

• A life sciences company selected Definitive Healthcare in a new-logo deal worth several hundred thousand dollars after struggling with stale data and the complexity of ingesting and interpreting claims. Monthly-refreshing claims delivered through custom data feeds let its teams focus on acting on data rather than interpreting it, while our reference and affiliation data, layered on top of the claims, enabled the right conversations with the most impactful physicians treating patients in need. This win highlights the power of pairing differentiated claims with our reference and affiliation data.

• A medical malpractice insurer expanded its relationship with Definitive Healthcare in a six-figure upsell secured with its renewal, roughly doubling its overall spend. The customer now uses our reference and affiliation data as the data foundation for its underwriting and risk modeling, while all-payor claims inform where to focus growth, replacing outdated legacy risk indicators. A direct Snowflake share that replaced manual file transfers was also a key factor, underscoring the value of our integrations.

Financial Guidance and Conference Call

As previously announced on September 2, 2026, the Special Committee of the Board of Directors, consisting solely of independent and disinterested directors, received a non-binding indication of interest from Advent International, L.P. ("Advent") to acquire all outstanding shares of the Company's Class A common stock and all outstanding limited liability company interests of AIDH TopCo, LLC, in each case, not already owned by Advent or Jason Krantz⁷, the Company's founder and Executive Chairman. In light of this development, Definitive Healthcare will not provide financial guidance or host a conference call to discuss its third-quarter 2026 financial results.⁸
