Aspen Standard Wealth, a New York-based RIA aggregator, announced Tuesday the acquisition of Cullen Investment Group, a Lafayette, Louisiana-based registered investment advisor with over $1 billion in assets under management. The deal, which closed this week, marks Aspen's fourth acquisition in 2026 and its tenth since launching its buyout strategy in late 2024.
With the addition of Cullen, Aspen's affiliated firms now collectively manage more than $16.5 billion in assets, according to figures extrapolated from previously disclosed transactions. The firm, backed by San Francisco private-equity firm Alpine Investors and Evergreen Services Group, positions itself as a permanent owner, allowing partner firms to retain their names and leadership while gaining access to Aspen's capital, technology, and back-office support.
Cullen, founded in 1986, began as Lafayette's only locally owned full-service brokerage. It now operates as an SEC-registered RIA, managing customized portfolios built around a disciplined value approach. Stephen Nickel, a principal at Cullen, said in a statement, "We are excited to partner with Aspen to build upon our legacy as an independent wealth management firm that is focused on providing our clients with a truly holistic experience. That commitment to our clients will never change."
Aspen's CEO, Aly Kassim-Lakha, praised Cullen's client-centric approach, saying, "The team at Cullen has built an incredible wealth management offering that places client best interests at the center of everything they do. We look forward to providing them with additional resources and capabilities to build upon that foundation and to continue to serve their clients with exemplary care for decades to come."
Busy year for Aspen
The Cullen acquisition is the latest in a string of deals for Aspen in 2026. In February, the firm hired Kevin DiSano, former chief growth officer at Beacon Pointe Advisors, as president to drive organic growth across its affiliates. In March, it acquired BlueSky Wealth Advisors, a New Bern, North Carolina firm with roughly $1 billion in assets. In July, Aspen added about $1.3 billion in assets with the purchase of CWS Financial Advisors, a Kalamazoo-based fee-only firm founded in 1983. Shortly after, it entered Colorado by acquiring Denver Private Wealth Management, a boutique overseeing approximately $550 million.
Aspen's buying spree began in November 2024 with Summitry, a San Francisco Bay Area firm then managing $2.8 billion. At the time, Kassim-Lakha said, "Aspen offers what successful, leading RIAs like Summitry have long been looking for: a deeply knowledgeable, permanent partner who is there to support them indefinitely."
Mid-sized RIAs in demand
Cullen fits the profile of firms currently attracting the most buyer interest. In its 2026 deal report, Advisor Growth Strategies noted that RIAs managing $500 million to $5 billion are "firmly in the crosshairs" as they evaluate potential acquirers. The overall M&A environment remains robust: Echelon Partners counted 120 RIA transactions in the second quarter of 2026, contributing to a 262-deal first half. The consultancy projects roughly 500 deals for the full year, which would surpass the 2025 record of 466.
A new analysis by ISS Market Intelligence found that retail-focused RIAs drew 9,525 representatives from other channels between 2021 and 2025, compared with 5,780 for independent broker-dealers. This activity is spread across various aggregator models, including platform operators like Dynasty, strategic acquirers like Hightower, and roll-up aggregators like Mariner. ISS also identified emerging aggregators planning aggressive buying, noting that "the scale of activity in the market means aggregators are not limited to simply one approach, with firms unveiling new divisions that act more like roll-up aggregators, such as Hightower's Signature Wealth."
For advisors considering succession options, the trend underscores the value of mid-sized RIAs. As Verdence Capital Advisors' recent $5B milestone shows, consolidation is reshaping the landscape. Similarly, phased succession deals are becoming more common, offering owners flexibility. However, not all transactions proceed smoothly, as evidenced by a valuation dispute lawsuit filed by a retiring partner. Aspen's model of permanent ownership aims to avoid such conflicts, but the market's rapid pace suggests continued scrutiny.
