Investors Bank, rooted in the American banking landscape, has a rich history dating back to 1926 when it was initially incorporated as the Washington Rock Building and Loan Association. Its journey saw a name change sixteen years later to Investors Savings and Loan Association, which through various mergers, acquisitions, and internal expansions, later transitioned into Investors Savings Bank. The bank underwent significant transformations over the years, notably in 1997, when it transitioned from a New Jersey-chartered mutual savings bank to a New Jersey-chartered stock savings bank. This reorganization saw the birth of a two-tiered holding company structure, with the bank becoming a wholly-owned subsidiary of Investors Bancorp, Inc. In 2005, the holding company became partially public, trading on NASDAQ, and by 2014, it became fully public. However, 2022 marked a significant milestone when Investors Bank was acquired by Citizens Financial Group, with all its locations rebranded as Citizens Bank by February 28, 2023​.

However, the exact number of states they operated in besides New Jersey and New York, and their specific banking policy remain elusive as the available resources do not provide a clear delineation of these details. Furthermore, the number of branches is specified as 'over 150,' but a precise count is not provided. Even though there's a mention of Investors Bank branches across the United States on a bank listing site, it doesn't provide a definitive number of states the bank operated in nor does it provide further insights into the bank's policies​​.

Thus, while we have a substantial narrative of Investors Bank’s journey and its structural details, some facets like the number of states they operated in and their precise banking policies require further exploration.
