The United States mental health mergers and acquisitions (M&A) market has demonstrated a dynamic and often resilient trajectory from 2020 through Q3 of 2025. This period has been characterized by substantial growth, primarily fueled by a surging demand for mental health services, a demand significantly exacerbated by the COVID-19 pandemic, a push toward scalable, integrated care models coupled with heightened interest from private equity firms and transformative technological advancements. While the market experienced a notable dip in deal volumes during 2023 and parts of 2024, largely attributable to macroeconomic headwinds such as elevated interest rates and increasing regulatory scrutiny, a robust rebound has been observed in 2025.
This pattern suggests that while the sheer number of transactions may fluctuate with broader economic conditions, the fundamental value and inherent investor interest in mental health assets remain robust. The underlying and persistent demand for mental health services acts as a strong counter-cyclical force, making the sector attractive even when other industries face declines.
In the rapidly evolving mental health sector, mergers and acquisitions (M&A) have played a pivotal role in shaping the industry's landscape. An analysis of transaction data from 2020 through Q3 2025 reveals distinct dynamics in buyer types, transaction volumes, and the evolving focus on various treatment modalities.
Overall M&A Activity: A Rollercoaster Ride
Examining the number of M&A transactions by type of buyer / transaction - per year (see chart below), we observe a significant surge in overall M&A activity from 2020 to 2022, followed by a moderation in 2023 and 2024, and a resurgence in 2025. With 73 transactions already recorded through Q3 2025, this year appears to be on track to surpass 2023 and 2024, indicating a renewed appetite for M&A.
Looking at the "Number of M&A Transactions by Type of Buyer - Per Quarter" chart (see below), the quarterly fluctuations provide a more granular view. Q1 and Q2 of 2022 showed particularly high activity, followed by a general downtrend in transaction volume per quarter through 2023 and 2024. However, 2025 stands out with a noticeable spike in activity through three quarters since 2022.
Buyer Dynamics: Strategic and Platform Deals Dominate
The M&A landscape in mental health is predominantly shaped by "Strategic" buyers and "Platform of PE" (Platform of Private Equity) deals. These two categories consistently represent the largest share of transactions, both in terms of numbers and percentages. The US mental health market is highly fragmented. This structure is ideal for Private Equity (PE) firms to execute "roll-up" strategies.
“Platform of PEs” have a substantial presence in the mental health M&A landscape. This heightened interest stems from their recognition of the significant demand-supply imbalance that presents compelling growth opportunities. These firms are strategically prioritizing investments in high-quality providers and actively pursuing add-on acquisitions to enhance growth and achieve greater scale.
From the "Percentage of M&A Transactions by Type of Buyer/Transaction - Per Year" chart (see below), it's evident that "Strategic" buyers and "Platform of PE" consistently account for the vast majority of quarterly M&A activity, often collectively exceeding 70-80% of all transactions. While their individual percentages fluctuate quarter to quarter, they remain the dominant forces. "PE buyout" also maintains a significant, albeit smaller, presence, typically ranging from 10-30%. "PE Follow on" and "PE Secondary buyout" generally represent smaller portions of the market.
Evolving Focus: Psychiatry and Talk Therapy Remain Core
The "Percentage of M&A Transactions per Year by Type of Treatment" chart reveals clear trends in the areas of focus within the mental health sector:
Psychiatry (Dark Blue) and Talk Therapy (Orange): These two modalities have consistently formed the backbone of M&A activity. In 2020, Talk Therapy services were part of over 25% of transactions and Psychiatry around 25%. While their individual proportions fluctuate, they collectively remain the dominant areas, often accounting for over 50-60% of all deals. Notably, Psychiatry's share has seen a significant increase over time, rising from around 25% in 2020 to over 30% in 2024, suggesting a growing interest in medication management and psychiatric services.
Hospitalization (Light Blue) and Residential Treatment (Green): These categories generally maintain a smaller, yet consistent, share of M&A deals, indicating ongoing but not rapidly expanding interest in more intensive care settings.
TMS (Gray), IOP (Dark Green), and PHP (Brown): These categories maintain relatively stable, smaller percentages of M&A activity throughout the period.
Psychedelics (Yellow): This emerging category, while starting from a very small base (almost negligible in 2020), shows a notable increase in its share of M&A transactions, particularly in 2022 and 2023. It has reduced its percentage in 2024 and 2025.
Conclusion
The M&A landscape in the mental health sector from 2019 to Q3 2025 showcases a dynamic environment driven primarily by "Strategic" and "Platform of PE" buyers. After a boom in 2021-2022, the market stabilized in 2023-2024, with 2025 indicating a renewed upward trend in transaction volumes. Traditional services like psychiatry and talk therapy remain central to M&A activity. This continued M&A activity reflects a robust and evolving industry responding to increasing demand for mental healthcare services.
(*) Notes:
This analysis:
Includes companies that offer outpatient services, in person or via telehealth, B2C and/or B2B, offering psychiatry, medication management, talk therapy, TMS, ketamine and esketamine therapies and other psychedelic treatments. It also includes mental health hospitals, and residential, IOP, and PHP treatments.
Types of transactions and buyers:
PE (Buyout): Transactions by private equity firms (“PE”).
PE (Secondary Buyouts (SBOs)): Sale of companies by one PE to another PE.
PE (Platform): Typically, after closing of an M&A by a private equity, the acquired company (“Platform”) grows through acquisitions (“add-ons”) of smaller firms and de novo locations. The acquisitions of those smaller companies are registered here.
Strategic Buyer: These are acquisitions made by a company that is not a PE, nor a Platform of a PE.
The study only includes what is widely understood as mergers and acquisitions and does not include private placements, i.e., acquisitions of shares and debt instruments by private investors when a company sells newly issued shares or debt. These transactions are regulated by the U.S. Securities and Exchange Commission and usually executed applying a federal exemption, like rule 506 (b).
