About BrightSphere Investment Group Inc.

BrightSphere Investment Group Inc. is a United States-listed asset management company that has historically traded on the NYSE and has since undergone a major rebranding into Acadian Asset Management Inc. effective January 1, 2025, with trading under the new NYSE ticker beginning January 2, 2025. For international investors, the key point is that the company’s economic profile is now centered on Acadian Asset Management LLC, its majority-owned operating subsidiary, while the corporate headquarters remains in Boston, Massachusetts, United States. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1748824/000174882425000016/aami-20241231.htm)) The company’s core business is systematic investment management. Acadian, founded in 1986, offers institutional investors around the world access to a diversified suite of systematic investment strategies designed to address a range of return and risk objectives. Its investment philosophy is explicitly data-intensive and rules-based, emphasizing a fundamentally grounded, highly structured process intended to identify market inefficiencies across a broad universe of securities and markets. The platform spans active equity strategies such as global, international, emerging markets and small-cap equities, alongside credit and alternative strategies. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1748824/000174882425000016/aami-20241231.htm)) From a competitive standpoint, BrightSphere operates in a crowded and highly performance-sensitive segment of the asset management industry. Its differentiation depends on the consistency of investment results, the robustness of its quantitative research process, client retention, and the ability to scale across institutional mandates. The business model is fundamentally linked to assets under management and fee generation, making market appreciation, net flows and strategy-level performance critical drivers of revenue and earnings. In 2024, the company reported approximately $117.3 billion of assets under management, highlighting meaningful scale, but also a material concentration in a few flagship strategies.

The principal executive office is in Boston, and Acadian also maintains secondary offices in London, Singapore and Sydney to support research, distribution and client servicing. Client assets are diversified across the U.S., Europe, Asia, Australia and other regions, which gives the franchise a broad international footprint and reduces dependence on any single market. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1748824/000174882425000016/aami-20241231.htm)) Recent developments are important for investors following SEC Form 4 insider activity: the company’s 2025 rebranding from BrightSphere Investment Group Inc. to Acadian Asset Management Inc. and the corresponding stock symbol change from BSIG to AAMI mark a significant corporate transition. This does not alter the underlying investment franchise, but it is a major market-facing event that affects identification, comparability and screening for investors tracking the legacy BSIG name.
