S & Co., Inc., a Massachusetts corporation ("SCI", the “Firm” or “we”), provides investment advice to individuals (primarily high net worth individuals), trusts, estates and charitable organizations. A substantial part of SCI’s business involves providing investment advice to trustees of revocable and irrevocable trusts to assist in the management of trust assets. Clients are primarily members of the Saltonstall family. While SCI has been in business since 1988, the firm’s history began shortly after 1922 when Leverett Saltonstall, assisted by Richard Saltonstall, established a family trust office to manage and administer family trusts and related family matters. Over time, the office grew to a size such that in 1988 SCI was organized and registered with the SEC as an Investment Adviser. SCI is wholly-owned by Neil L. Thompson, Matthew E. Megargel, Nathaniel Jeppson, G. West Saltonstall, Thomas V. Quirk, Jeffrey L. Thompson, and Brian F. McCarthy. SCI has no direct or indirect subsidiaries. SCI is an affiliate of Saltonstall & Co. LLP, a firm of private trustees and executors that can trace its history to 1922. Saltonstall & Co. LLP offers fiduciary and tax services to many of SCI’s clients that are trusts, estates and foundations, and it maintains offices at the same location as SCI, at 50 Congress Street, Room 800, Boston, MA 02109. The current officers and directors of SCI are: Neil L. Thompson (Chairman of the Board of Directors); Matthew E. Megargel (Director, Senior Vice President and Clerk); Nathaniel Jeppson (Director, President, and Chief Compliance Officer); G. West Saltonstall (Vice Chairman of the Board of Directors); Thomas V. Quirk (Director and Senior Vice President); Jeffrey L. Thompson (Director and Vice President); and Brian McCarthy (Director, Vice President and Treasurer). Biographical information relating to these individuals is set forth in the Brochure Supplement that appears at the end of this Brochure. Continuity

of being privately owned for over ninety years has been integral to perpetuating SCI’s fiduciary culture, where serving as a trusted advisor to clients is the primary objective. The Firm believes that operating without distractions and pressure associated with being a public company or having outside shareholders is essential to avoiding many conflicts of interest pervasive in the financial services industry. We are long-term investors focused on compounding after-tax wealth for clients. SCI invests primarily in public equities and typically has a bias toward high quality growth companies but considers stocks opportunistically, when they meet analytical criteria and appreciation expectations. The Firm also makes investments in outside funds. SCI selects external managers for expertise in niche areas (e.g. media, healthcare, international equities, venture capital, and distressed credit) that are typically outside of internal capabilities but which offer diversification benefits and meet long-term return objectives. SCI often tailors investment advisory services to clients, who are free to impose restrictions on investing (or not investing) in specific securities, industries, or asset classes. For example, a client may request a particular industry be excluded from their portfolio in order to maintain professional impartiality requirements or other personal preferences. SCI does not participate in any so-called “wrap fee programs”. Instead, SCI charges its clients a separate fee for the investment advisory services that SCI provides; these fees are described in Item 5 below. In addition, clients of SCI obtain custodial services from, and pay a separate fee to, the qualified custodian holding client assets. These fees are described in more detail in Item 5 below. SCI only manages client assets on a discretionary basis. As of December 31, 2023, SCI managed client assets having a market value of approximately $2,114,986,938.
