Springline Advisory, a Top 100 Firm based in Dallas, has acquired Actuarial Resources Corporation, a Kansas City-based actuarial software and consulting firm.

The firms plan to expand their capabilities in actuarial consulting and software development with an enhanced range of advisory services.

"What stood out to us about ARC wasn't just their technical excellence; it was the way they consistently show up for their clients and stay committed to solving complex actuarial challenges in ways that make insurers stronger and more adaptive," said Springline Advisory CEO Tim Brackney in a statement Wednesday. "Their software expertise and client-first culture make them a natural fit for our vision to build the most forward-thinking advisory firm platform in the industry."

ARC dates back to 1987 and provides actuarial software and consulting services to over 50 insurance companies for the valuation of life, annuity, and health insurance products.

"Joining Springline Advisory positions ARC to help build something bigger—a leading, national insurance practice with the scale, systems, and expertise to serve enterprise insurers end-to-end," said ARC managing partner Brenna Gardino in a statement. "It's an opportunity to amplify our actuarial and software capabilities, modernize with purpose, and continue delivering the accuracy and accountability our clients rely on."

Financial terms of the deal were not disclosed. Springline Advisory's annual revenue, including ARC, is $160 million. ARC is adding five partners, 46 team members and one office to Springline, which ranked No. 73 on Accounting Today's 2025 list of the Top 100 Firms when it earned $89 million.

In November, Springline acquired Infinity Globus and Smart Accountants, both based in Ahmedabad, India, expanding the firm's international reach. Springline was created by private equity firm Trinity Hunt Partners in January 2024. It has made several M&A deals, adding HM&M and Clark, Raymond & Co. last December, Fiske Advisory in January, and EFPR Advisory in February.

Sorren adds RTO

Sorren, based in Meridien, Ohio, has expanded in the Pacific Northwest by adding RTO & Co., based in The Dalles, Oregon.

RTO was founded in 1946 and caters to clients in the agriculture, health care, government, nonprofit organizations, retail and individual sectors.

"RTO & Company has an incredible legacy of service, strong client relationships, and a deep connection to the community—all values that align perfectly with Sorren's vision," said Sorren president Josh Tyree in a statement Wednesday. "Together, we're strengthening our ability to serve Oregon businesses with the personal attention of a local firm backed by the reach and resources of a national network."

Sorren was formed in May through the combination of 13 regional firms with private equity backing of DFW Capital Partners. In October it acquired Healthworks, a health care consulting firm specializing in health care disputes and arbitration hearings. Financial terms of the latest deal were not disclosed.

"This partnership opens the door to tremendous opportunities for our clients and our team," said RTO managing partner Nate Reagan in a statement. "With Sorren, we can deliver broader capabilities and innovative solutions while continuing to offer the trusted, high-quality service our clients have relied on for generations."
