In these arrangements, Boston Common makes decisions regarding what securities should be bought and sold for the wrap client’s account; the wrap sponsor selects the brokers that will effectuate the transactions. Boston Common is required to direct all brokerage transactions to the sponsoring broker-dealer. Execution prices are often less favorable than execution prices achieved in non-wrap accounts. Generally, Boston Common may terminate its participation in a wrap program upon thirty days’ notice. Please refer to Item 12 for a more complete discussion of the effects of Directed Brokerage. Model Manager – Third Party Platforms Boston Common’s services are also offered on third-party Unified Managed Account (“UMA”) platforms managed by other investment advisers. In these cases, Boston Common does not make any investment decisions on behalf of these accounts, but provides a Model Portfolio subject to Boston Common’s comprehensive sustainability guidelines that the client’s manager may use to invest client accounts. Boston Common refers to these advised accounts as “Licensed Model Portfolio Assets.” Firm Ownership Boston Common is majority owned by 21 of its employees/former employees and Geeta Aiyer, the firm’s Founder, President and largest employee shareowner (22.25%). A minority stake of 15% is owned by an outside private entity: BC Acquisition LLC. Assets under Management As of December 31, 2025, Boston Common managed approximately $4.4 billion in assets. In addition, it advised, on a non-discretionary basis, approximately $644 million in Licensed Model Portfolio Assets. Item 5: Fees and Compensation Generally, clients are charged advisory fees based on a specified percentage of their assets under management, assessed quarterly. “Assets under Management” means the market value of all securities and cash over which Boston Common has investment discretion. “Assets under Advisement” means Licensed Model Portfolio Assets, where the assets are managed by third-party advisers and Boston Common provides a model that the adviser may apply. Boston Common receives a fee based on the assets in the account. Page 11 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Boston Common’s current practice is generally to bill new accounts in advance based on the client’s assets under management on the last day of the previous calendar quarter. If an advance-bill client’s account is terminated in the middle of a quarter, all pre-paid, but unearned fees, are returned and Boston Common retains a pro-rated amount of fees. When a client opens an account in the course of a quarter, the client will be charged a pro-rated fee for the quarter based on the beginning account balance. Some of Boston Common’s clients are billed in arrears, with the value of client assets being determined on the last day of the quarter. If a client that is billed in arrears terminates an account in the middle of the quarter, Boston Common will charge the client a pro-rated fee for the days that the account was managed in the quarter. In most instances, management fees are directly debited from the client accounts. In the case of certain commingled vehicles, noted below, Boston Common pays for the administrative costs associated with the commingled vehicle, including custody costs. MANAGEMENT FEES Boston Common’s standard annual asset-based fee schedule and minimum account sizes are generally as shown below. In some cases, fees for clients are negotiated and may vary from those stated above. Fees for some accounts may be higher or lower than those stated in the standard fee schedule above, depending on account size and the services to be rendered. There are also instances where Boston Common may waive account or relationship minimums in certain circumstances. Boston Common also manages “courtesy accounts” for which no management fees are charged. A.

D. Wrap Fee Accounts Boston Common offers investment advisory services on a discretionary basis to clients of sponsoring broker-dealers or financial consultants who offer comprehensive brokerage, custodial and advisory services for a comprehensive “wrap-fee,” which is typically based on the amount of client assets under management. No Boston Common personnel or affiliates are sponsors of wrap-fee programs. The wrap program sponsors remit a portion of the fees to Boston Common. Boston Common’s fees for providing investment advisory services to the sponsored accounts range from 0.70% to 1.00% of the assets that have been allocated to it for management. This range is determined by Boston Common and the sponsoring broker-dealer or financial consultant. Fees are generally due quarterly, payable in advance. All prepaid, unearned fees are refunded on a pro-rata basis when the client closes the account. Generally, Boston Common may terminate its participation in a wrap program upon thirty days’ notice. Under the wrap-fee arrangements, the financial intermediaries deliver Boston Common’s Form ADV Part 2A, 2B, and Form CRS to the client. In these arrangements, Boston Common is required to direct all brokerage transactions to the sponsoring broker-dealer. In these arrangements, execution prices are often less favorable than execution Page 16 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  prices achieved in non-wrap accounts. Please refer to Item 12 for a more complete discussion of the effects of Directed Brokerage. E. Licensed Model Portfolio Assets Boston Common also provides services on third-party platforms managed by other investment advisers. In these cases, Boston Common does not make any investment decisions on behalf of these accounts, but provides a Model Portfolio that the client’s manager may use to invest client accounts. In these arrangements, Boston Common receives a fee ranging between 0.25% and 0.50%, based on the amount of the assets in the account. These accounts generally are billed quarterly in arrears, with the value of client assets being determined on the last day of the quarter. If a client that is billed in arrears terminates an account in the middle of the quarter, Boston Common will charge the client a pro-rated fee. F. Soft Dollars and Commission Recapture Boston Common receives benefits, including research products and services, through its trading relationships with certain brokers in consideration for commissions paid by clients. This causes the price the firm pays in a securities transaction to be higher than the lowest possible execution price. Please refer to Item 12 for a more complete discussion of Boston Common’s use of soft dollars. Fee Summary Advisory fees paid to Boston Common do not include all the fees a client pays in connection with the management of their portfolio. Some of these fees may be billed by other service providers or embedded in their transaction pricing. Additional fees and expenses may include, but are not limited to: (1) custodial charges (except as specified above); (2) brokerage fees, commissions and other related transaction costs and expenses; (3) governmental charges, taxes and duties; and (4) transfer fees, registration fees and other expenses associated with buying, selling or holding investments, such as wire transfer and electronic funds transfer fees. These fees are generally deducted from the client’s account. For additional information about brokerage and other transaction costs, please refer to the section entitled “Brokerage Practices” in Item 12. Page 17 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Item 6: Performance-Based Fees and Side by Side Management Side-By-Side Management Disclosures Even though Boston Common does not charge performance-based fees, it has different fee structures and some clients pay a higher fee for management services. This creates an incentive for Boston Common to favor those accounts in order to increase its compensation. Additionally, some of Boston Common’s principals and/or employees have made personal investments in the firm’s products, including the mutual funds that the firm manages. This also creates an incentive for Boston Common to favor those accounts over other accounts. Since the firm puts the interest of its clients first, it takes the following steps to address these conflicts: a. It discloses to clients the existence of material conflicts of interest, including the potential for the firm and its employees to earn more compensation from certain advisory clients; b. It has implemented policies and procedures for fair and consistent allocation of investment opportunities among all client accounts; c. It reviews trading; and d. It educates its employees regarding the responsibilities of a fiduciary, including the need for having a reasonable and independent basis for the investment advice provided to clients and equitable treatment of all clients, regardless of the fee arrangement. Item 7: Types of Clients taxable and Boston Common provides investment advisory services to pension and profit sharing plans, high net worth individuals, charitable organizations, state and local entities, institutional clients, private tax-exempt commingled vehicles and mutual funds. Boston Common has established account minimums for individually managed client accounts and its various investment vehicles. Please refer to the fee tables in Item 5. The firm may, however, waive the minimums at its discretion, based on, but not limited to, such factors as a pre-existing relationship with the client, the potential for additional growth or contributions to the account, or for specific products. Page 18 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Item 8: Methods of Analysis, Investment Process and Risk of Loss I. In-House Strategies--Methods of Analysis and Investment Process a. Screening the Investment Universe for non-AMRIS strategies Boston Common begins the equity selection process by creating a diversified monitor list of what the investment team believes are high- quality stocks. For U.S. strategies, Boston Common starts with the investable universe of U.S. stocks with market capitalizations above $2 billion USD. For the International and Global strategies, it constructs a monitor list of securities drawn from the MSCI EAFE, MSCI ACWI and ACWI ex-USA benchmark, adjusted later in the process for international portfolios using the MSCI EAFE benchmark and the universe of emerging market ADRs and ordinary shares. For the Emerging Markets strategy, it constructs a monitor list of securities drawn from the MSCI EM benchmark. Boston Common screens these lists using statistical metrics such as capitalization, liquidity, profitability, and leverage as well as sustainability criteria. These screens exclude companies that have consistently lost money, that have taken on unsustainable levels of debt, or that have that Boston experienced such volatile operating performance Common would not be confident in making projections about their future profitability. Boston Common further excludes from the list companies whose business models the investment team considers unsustainable and whose financial reporting and managerial accountability Boston Common considers untrustworthy. Boston Common has also created proprietary data sets reflecting the sustainability characteristics of a broad set of global companies. This information is used in the preliminary screening of the investment universe. Based on the result of the preliminary screening process, Boston Common adds to the monitor lists a selection of mid-sized companies in areas with high sustainability impact in order to restore sufficient diversification. This process produces a monitor list of stocks that Boston Common views as high-quality. We enhance our financial research through the inclusion of sustainability risk and opportunity factors. Boston Common employs a separate, in-house sustainability research team that works closely with the financial research team, together forming our Integrated Investment Team. These highly qualified teams have a long history of working together, enhancing our fully integrated approach. While we purchase third-party research, we believe we have an advantage in having a seasoned sustainability research team with global experience who can ferret out additional, proprietary information about Page 19 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  companies. Our experienced financial research analysts cover the global sectors in which they have developed specific expertise, generating stock ideas and monitoring both our holdings and market dynamics. With our low portfolio turnover, our analysts focus on understanding the longer-term value drivers for a company and its industry. Simultaneously, our dedicated sustainability staff undertakes their own rigorous review process for new securities across all sectors. This process remains independent of our financial research, so as to prevent bias and add an independent perspective. Boston Common also uses its voice on behalf of clients to raise sustainability issues with management of select portfolio companies based in the U.S. and other countries through a variety of channels. These may include engaging in dialogue with management, voting proxies in accordance with our comprehensive sustainability guidelines, and participating in the annual shareholder meeting process. Through these efforts, Boston Common encourages company managements towards greater transparency, accountability and commitment to sustainability issues. In the long run, we believe that targeted, coordinated engagement can generate both impact and alpha. b. Stock Selection and Portfolio Construction for non AMRIS strategies Boston Common’s research next focuses on identifying individual stocks from the monitor list that appear to be trading at a discount to intrinsic value and to have potential catalysts to realizing that value over the next twelve to eighteen months. To manage risk, Boston Common quantifies reasonable downside, based on historical analogs and on the intrinsic value that would be justified in alternative scenarios. Boston Common looks at developments across an industry to understand fundamental factors such as pricing trends, product cycles, supply-demand imbalances, and the potential for consolidation. Through this process, it identifies individual companies that appear to provide the most opportunity and, by extension the most attractive sectors and industries available in the markets. Boston Common forms an outlook for each stock under investigation and models expected outcomes. In addition, the investment team assesses the projections made by Wall Street securities analysts to better understand what expectations are built into the current stock price and to assess whether the company can meet or exceed them. The measures Boston Common uses to understand a company’s fundamentals and valuation vary by industry. Boston Common uses a variety of information to build a valuation model appropriate for the Page 20 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  nature of the company and industry, often by valuing a company’s projected future cash flows discounted by its cost of capital. For a company with relatively stable earnings, Boston Common may use its price-to-earnings valuation relative to its history as an indicator of its upside potential. The firm’s stock selection produces a buy list for each of the investment strategies composed of stocks that the investment team believes are high quality and trade below their intrinsic value. Global portfolios draw on selected stocks from the buy lists of the U.S. and international strategies. Using these stocks, Boston Common builds model portfolios, which are then customized for specific client guidelines and objectives as appropriate. that the investment team believes offer When all else is equal, Boston Common prefers to weight holdings according to its fundamental conviction in the entities’ attractiveness and according to the predictability of their business models. Boston Common will typically buy a position of up to three percent in securities the most opportunity, or possibly a greater amount for an attractive stock that comprises a large proportion of the portfolio’s benchmark. Boston Common generally does not establish positions of greater than five percent in a particular issuer. Boston Common manages broadly-diversified portfolios with exposure to the major sectors and, for international portfolios, geographical regions of the market. The investment team determines sector allocation by evaluating the macro-economic environment, the fundamental outlook of each sector and its constituent stocks, and both sector-level and stock-level valuation. The firm’s analysts drive some of the allocation decisions by identifying industries with the most opportunity and generating stock ideas within them. The firm typically maintains major sector weights within a band of 50% to 200% of the corresponding sector weights in the portfolio’s benchmark, and will rebalance as necessary to meet those guidelines. Boston Common manages risk in its International, Global and Emerging Markets strategies on a geographic basis, maintaining diversified exposure to the major regions in MSCI EAFE, ACWI, ACWI ex USA and MSCI EM Indexes, depending on the product. In addition to its Emerging Markets strategy, Boston Common typically maintains and monitors a tactical allocation to emerging markets in its international and global strategies. Boston Common also manages balanced accounts. Debt instruments and preferred stocks may be purchased in balanced accounts and, where permitted by investment guidelines, in equity accounts. Accounts may be invested in convertible preferred stock where this type of stock is deemed more attractive than common stock. Page 21 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Community bank certificates of deposit and community loan funds may be selectively used in client accounts where requested and appropriate, given client investment and sustainability guidelines. c. Sustainability Criteria for non-AMRIS strategies We seek companies with strong sustainability attributions from both a product and process perspective, that meet our comprehensive sustainability guidelines (required for inclusion in the investable universe), and where we determine we can create a positive sustainability momentum through active engagement in order to generate alpha. in relation We have some absolute exclusions to weapons manufacturers, gaming, alcohol, tobacco, and companies whose primary revenues are from mining coal, transporting thermal coal or burning coal for electric power generation. These negative screens are based on whether a company makes a defined proportion of its revenues (typically > 5%) from these activities. We favor firms with:  Superior records in environmental responsibility, labor relations, and human rights that display a commitment to international standards and compliance and that demonstrate improving records in these areas. We also look for companies with innovative, desirable products and sustainable business models. We prefer companies that allow shareholders to influence strategic decision- making, exhibit Board diversity and independence and who align their interests to enhance long-term versus just short-term value. We avoid companies that:  Are egregious violators of regulations;  Exhibit a pattern of negligence;  Have consistently poor sustainability records;  Have a history of knowingly using forced or child labor;  Who engage in irresponsible marketing; or  Have a deteriorating record on measurable conduct. These criteria apply to a company’s suppliers and contractors as well. Boston Common integrates financial and sustainability factors into our investment process because we believe sustainability research helps us identify companies that will be successful over the long-term. We seek impactful companies that can capitalize on new market improvements and avoid opportunities, implement efficiency Page 22 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  from inadequate attention risks. As a to unanticipated costs stemming sustainability result, Boston Common believes sustainability research helps improve portfolio quality and financial return potential. While sustainability factors might omit a company from our universe that another fundamental manager might retain, we believe that companies that minimize their risks will outperform in the long-term. We believe that long-term oriented decision-making will improve the fundamentals of the companies that we invest in, eventually becoming reflected in the value of the shares. These improvements may take the form of lower risk premia, higher earnings, cost savings product or process innovation, or policy changes. We enhance our financial research through the inclusion of sustainability risk and opportunity factors. Boston Common employs a separate, in-house sustainability research team that works closely with the financial research team, together forming our Integrated Investment Team. These highly qualified teams have a long history of working together, enhancing our fully integrated approach. While we purchase third-party research, we believe we have an advantage in having a seasoned sustainability research team with global experience who can ferret out additional, proprietary information about companies. Our experienced financial research analysts cover the global sectors in which they have developed specific expertise, generating stock ideas and monitoring both our holdings and market dynamics. With our low portfolio turnover, our analysts focus on understanding the longer-term value drivers for a company and its industry. Simultaneously, our dedicated sustainability staff undertakes their own rigorous review process for new securities across all sectors. This process remains independent of our financial research, so as to prevent bias and add an independent perspective. Boston Common also uses its voice on behalf of clients to raise sustainability issues with management of select portfolio companies based in the U.S. and other countries through a variety of channels. These may include engaging in dialogue with management, voting proxies in accordance with our comprehensive sustainability guidelines, and participating in the annual shareholder meeting process. Through these efforts, Boston Common encourages company managements towards greater transparency, accountability and commitment to sustainability issues. In the long run, we believe that targeted, coordinated engagement can generate both impact and alpha. d. All Material Risk Boston Common also implements the All Material Risk financial data analytics (AMR) which ingests data from primarily regulatory filings. Page 23 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  These regulatory filings are governed by legal frameworks such as Reg S-K for US listed securities and IFRS and country-level legal frameworks for non-U.S. listed securities. These regulatory filings are then entered into a proprietary modeling platform which parses each filing to detect, delineate, index, and review risks. Once reviewed, the overall risks are further subdivided and classified by ontology, subtopic, and severity. Risks will then be grouped into 485 risk categories and scored on a severity scale of one (1) to five (5). Once grouped and scored, these risks are further synthesized using test parameters to create test portfolios featuring companies with similar risks to determine if the risks explain the pricing of a particular security. Results from risk category and severity scale synthesis are classified into three risk categories: endured risk, priced risk, and penalized risk. Endured risks are material risks but do not affect a security’s price. Penalized risk are material risks that do negatively affect the price of a security. And priced risks are risks that are material and do positively affect the price of a security. Once penalized risk and price risk are determined, the investment team can then use the risk calculations to overweight or underweight individual securities relative to the MSCI EAFE, ACWI, ACWI ex USA, and MSCI EM Indexes, depending on the product. The firm typically maintains major sector weights within a band of 50% to 200% of the corresponding sector weights in the portfolio’s benchmark, and will rebalance as necessary to meet those guidelines. In addition to its Emerging Markets strategy, Boston Common typically maintains and monitors a tactical allocation to emerging markets in its international and global strategies. Boston Common aims to create broadly-diversified portfolios that take into account complex risks highlighted in regulatory filings. These risks are then codified and provide the investment team another input while constructing portfolios. By focusing on risks in highly material but complex regulatory filings not easily absorbed by the market, we can form a differentiated perspective that is highly useful in interpreting how a myriad of risks are likely to impact the valuation of a security. Using AMR data analytics derived from the All Material risk modeling platform, the investment team can capitalize on increased available data to supplement our fundamental research and risk management approach. In the long run, we believe that utilizing data analytics can generate alpha. II. All Material Risk Investment Strategy--Methods of Analysis and Investment Process a. Creating the Investment Universe Page 24 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Boston Common begins the equity selection process for the All Material Risk Investment Strategy (AMRIS) by selecting a broad market segment. For U.S. strategies, Boston Common starts with the 1000 largest U.S. companies. For the International and Global strategies, it constructs a list of securities drawn from the MSCI EAFE and MSCI ACWI. b. Stock Selection and Portfolio Construction Once the investment universe has been created, AMRIS’ proprietary modeling platform ingests data from primarily regulatory filings. These regulatory filings are governed by legal frameworks such as Reg S-K for US listed securities and IFRS and country-level legal frameworks for non-U.S. listed securities. The model parses each filing to detect, delineate, index, and review risks. Once reviewed, the overall risks are further subdivided and classified by ontology, subtopic, and severity. Risks will then be grouped into 485 risk categories and scored on a severity scale of one (1) to five (5). Once grouped and scored, these risks are further synthesized using test parameters to create test portfolios featuring companies with similar risks to determine if the risks explain the pricing of a particular security. Results from risk category and severity scale synthesis are classified into three risk categories: endured risk, priced risk, and penalized risk. Endured risks are material risks but do not affect a security’s price. Penalized risk are material risks that do negatively affect the price of a security. And priced risks are risks that are material and do positively affect the price of a security. These risk categories inform the risk profile of each security within the investment universe Once penalized risk and price risk are determined, the modeling platform will then use the risk profile to reduce weights of those securities with penalized risk, with many securities weights reduced to zero. From this initial weighting, the modeling platform will then reweight the remaining securities based on market capitalization and company specific risk profiles. Portfolios are reweighted monthly. AMRIS also has the ability to customize portfolios given client- specific guidelines. These client preferences are implemented as further inputs into the modeling platform; and resultingly, creates a forward-looking portfolio design that aims to ensure that purpose and performance reinforce each other. III. Risk of Loss All investments in securities involve risk. It is possible that client investment objectives will not be achieved or that clients will lose all Page 25 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  or a portion of their investments. The risks investors face include the following:  General Market Risk: All securities investments are subject to changes in the market place. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issues in other countries or regions. General market risk may affect a single issuer, industry, sector of the economy or the market as a whole.  Investment Selection Risk: Boston Common’s analysis of an investment may be incorrect and may result in selections of investments that suffer losses or underperformance relative to other investments. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.  Foreign Securities Risk: Foreign securities, including ADRs, are subject to increased risks relating to adverse political, social and economic developments abroad. Foreign risks also include differences between U.S. and foreign regulatory requirements, taxation and market practices. In addition, foreign securities may be less liquid and harder to value than securities of U.S. issuers. Continued volatility in the Eurozone and financial instability in the region pose additional risks for investments in international securities.  Emerging Market Risk: The foreign securities risks are more significant for issuers in emerging market countries. Additional risks include immature economic structures and more thinly- traded securities markets.  Currency Risk: The value of foreign currencies relative to the U.S. dollar fluctuates in response to adverse market, political, social and economic developments abroad. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.  ADR Risk: ADRs may be subject to many of the risks associated with investing directly in foreign securities. These include foreign exchange risk connected with political and economic risks of the underlying issuer’s country. ADRs may involve additional risks, such as the risk that the sponsoring bank fails to support the ADRs Page 26 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  it issues. Also, the price movements of ADRs may not track perfectly those of the underlying foreign security.  Large Companies Risk: Larger, more established companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes. Also, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.  Small Companies Risk: Smaller, less established companies may be subject to greater variations in stock price, depending on a variety of factors. They may have smaller, less diversified product or service lines, limited capital or other resources, and less experienced or smaller managements. Small companies may be more susceptible to being negatively affected by economic downturns in comparison to large capitalization companies.  Growth Company Risk: The market price of stocks of growth companies may be more volatile and susceptible to fluctuations based on company earnings than market prices of other companies. Growth company stocks may underperform stocks of other companies when growth stocks are out of favor in the market.  Value Company Risk: The stocks of value companies can remain undervalued by market measures for long periods and fail to realize their expected value. Value company stocks may underperform stocks of other companies when value stocks are out of favor in the market.  Credit Risk: The issuer of a fixed-income security could default on its obligation to pay principal and/or interest or its credit rating could be downgraded. This risk is higher for fixed-income securities that are rated below investment grade.  Interest Rate Risk: As interest rates rise, the value of fixed- income securities is likely to decrease. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter durations. result in Boston Common  Sustainability (ESG) Policy Risk: Boston Common’s ESG policy could cause its clients’ accounts to perform differently compared to similar accounts that do not have such a policy. Its ESG policy may foregoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might otherwise be disadvantageous for it to do so. Boston Common will vote proxies in a manner consistent with its ESG Page 27 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  guidelines, which may not always be consistent with maximizing short-term performance of the issuer.  Real Estate Investment Trusts (“REITs”) Risks: REITs are trusts that invest primarily in commercial real estate or real estate- related loans. REITs may experiences losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes, and operating expenses in addition to terrorist attacks, war or other acts that destroy real property. REITs may be affected by changes in the value of their underlying properties and by defaults by borrowers or tenants. Some REITs may have limited diversification and may by subject to risks inherent in financing a limited number of properties. REITs generally depend on their ability to generate cash flow to make distributions to shareholders or unit holders and may be subject to defaults by borrowers and to self-liquidations. In addition, a REIT may be affected by its failure to qualify for tax- free pass-through of income under the Internal Revenue Code of 1986 or its failure to maintain exemption from registration under the 1940 Act. in effective investment decisions for  Data Science Investment Approach Risk: Boston Common’s All Material Risk Investment strategy relies on a proprietary data science enabled selection approach that utilizes proprietary techniques to process, analyze, and combine a wide variety of information, including the adviser’s multi-decade history of proprietary fundamental research, company financial statements, and other relevant data sources, to forecast the financial prospects of each security and to assess key risks. There is no guarantee that the use of the strategy’s proprietary data science approach will result the strategy, specifically to the extent the approach does not perform as designed or as intended, the strategy may not be successfully implemented and the strategy may lose value. designed or as intended,  The financial prospects of each security and to assess key risks. There is no guarantee that the use of the Fund’s proprietary data science approach will result in effective investment decisions for the Fund, specifically to the extent the approach does not perform the as Fund’s strategy may not be successfully implemented and the Fund may lose value. Page 28 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Item 9: Disciplinary Information Rule 206(4)-4 under the Advisers Act requires investment advisers to disclose any legal or disciplinary activities a client might reasonable want to know when deciding whether to hire the adviser. Neither Boston Common nor its personnel have any disciplinary, administrative, regulatory, criminal, civil, or otherwise reportable history to disclose. Item 10: Other Financial Industry Activities and Affiliations Boston Common is an investment adviser to three mutual funds, the Boston Common ESG Impact International Fund, Boston Common ESG Impact U.S. Equity Fund and Boston Common ESG Impact Emerging Markets Fund, which are three of a series of Professionally Managed Portfolios, a Massachusetts business trust registered with the U.S. Securities Exchange Commission as an open-end management investment company and administered by U.S. Bank Global Fund Services. AMG Funds/AMG Distributors Arrangements: Mutual Fund Sub-advisory Boston Common has mutual fund subadvisory agreement(s) with AMG Funds LLC, a wholly-owned subsidiary of AMG, under which Boston Common serves as subadviser to one mutual fund in the AMG Funds family of mutual funds, which are sponsored and advised by AMG Funds LLC. As described in each fund’s prospectus, the fund pays AMG Funds LLC an advisory fee, and AMG Funds LLC pays Boston Common a subadvisory fee with respect to the fund. The fees payable to Boston Common may be reduced by the amount of certain shareholder servicing fees, distribution related expenses, and other expenses paid by AMG Funds on behalf of the funds, under an agreement by which Boston Common has agreed to reimburse AMG Funds for a certain portion of these fees. Item 11: Code of Ethics, Participation or Interest in Client Transactions and Personal Trading As described in Item 7, Boston Common is an investment adviser to different types of clients. Boston Common may give advice and make different investment decisions for client accounts than it makes for its own account or for “access persons,” as that term is defined by the 1940 Act or the Advisers Act. Since these situations may involve potential conflicts of interest, Boston Common has adopted a Code of Ethics that sets forth the ethical standards of the firm. Page 29 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Code of Ethics As required by Rule 204A-1 under the Advisers Act and Rule 17j-1 under the 1940 Act, Boston Common has adopted a Code of Ethics that sets forth the basic policies of ethical conduct for all managers, officers, and employees of the firm. The Code of Ethics describes the firm’s fiduciary duties and obligations to clients and, among other things, sets forth the firm’s practice of supervising the personal securities transactions of employees. The firm and/or its employees may purchase or sell investments for their personal accounts which have been recommended to clients. The firm collects, maintains and reviews records of securities holdings and transactions made by employees. All employees are required to report their personal securities trades on a quarterly basis, and their holdings on an annual basis, to the Compliance Department. Duplicate copies of periodic brokerage statements are submitted to the firm electronically via our automated compliance system, Compliance Alpha for review. At least quarterly, the Compliance Department reviews employees’ personal trades to identify potential or actual conflicts of interest. Employees who violate the reporting requirements of the Code may be fined. Employees receive annual training on insider trading, ethical and professional conduct, social media usage, political contributions, and the importance of maintaining client confidentiality. The firm conducts conflicts of interest and insider trading checks by requiring employees to disclose connections that they and their immediate family have with public entities, including board memberships. In order to prevent even the appearance of partiality in dealing with vendors and others with whom Boston Common does business, employees are required to report all gifts and entertainment above $50 provided by or to any entity that does business with, or that seeks to do business with, the firm. Employees may not receive gifts or entertainment in excess of $200 a year without pre-approval by the Chief Compliance Officer. A copy of Boston Common’s Code of Ethics is available upon request for clients and prospective clients by contacting the Chief Compliance Officer at 617-720-5557. Item 12: Brokerage Practices Selection of Brokers Boston Common recognizes that brokerage is the property of the clients, and as such, is to be allocated to broker-dealers in a manner that serves the interests of the clients. It also recognizes an ongoing duty to ensure the quality of transactions by seeking to obtain best execution, minimize transaction Page 30 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  costs, and use client brokerage to benefit clients. While the firm endeavors to obtain the best combination of price and execution for its clients, “best execution” does not necessarily mean it will pay the lowest commission or spread. The firm seeks competitively priced brokerage services where the broker- dealer can provide value-added, company-specific, and thematic industry research, including meetings with management and conferences. The additional factors Boston Common reviews in selecting a broker-dealer include, but are not limited to: the liquidity of the market in a security; financial stability of the broker-dealer; the broker’s ability to handle a desired block; and    promptness of execution;  quality of settlement;   efficiency in clearing and settling trades. Trade Aggregation and Allocation When decisions are made to buy or sell the same security simultaneously for a number of accounts, Boston Common will aggregate the purchase or sale into a single trade order (an “aggregated” trade) if it deems this to be appropriate and in the best interests of the accounts involved. Aggregated trades may facilitate best execution, including negotiating more favorable prices, obtaining more timely or equitable execution, or reducing overall commission charges. When an aggregated order is filled in its entirety, each account participating in the aggregated order will participate at the average share price for the aggregated order. Transaction costs shall be shared pro-rata based on each account’s participation in the aggregated order. If an order cannot be completely filled and the investment opportunity is determined to be equally suitable and appropriate for more than one account, allocations will generally be made pro-rata, subject to rounding to achieve round lots, based upon the initial amount requested for an account participating in the aggregated order. Each account participating in a particular aggregated trade will receive the share price with respect to that aggregated order or, as appropriate, the average share price for all executed aggregated trades on that trading day. Boston Common may allocate on a basis other than pro-rata if, under the circumstances, such other method of allocation is reasonable, does not result in any improper or undisclosed advantage or disadvantage to other accounts, and results in fair access over time to trading opportunities for all eligible accounts. Page 31 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  At times, additional sustainability suitability or tax-related analyses need to be performed for clients with custom restrictions and tax sensitivities. As a result, trades for these accounts may be made days or weeks after other clients’ trades in the same securities. This may result in a different execution price being achieved for trades in these customized accounts, which may be better or worse than the trades implemented for client accounts that are not customized. Boston Common provides buy and sell recommendations to third-party platforms on behalf of the Licensed Model Portfolio Assets promptly upon completion of trading for Boston Common’s discretionary clients’ orders. Directed Brokerage Some clients designate a particular broker or dealer through which trades are to be made (“directed trades”). In addition, wrap-fee arrangements generally require Boston Common to direct all brokerage transactions to the sponsoring broker-dealer. Where a client directs trades, Boston Common is not able to negotiate commission rates or spreads, and is not able to obtain the same execution it receives for other clients. Directed trades are not aggregated with other clients’ orders, and are placed after the completion of non-directed trades. The prices for directed trades are not aggregated with the prices for non-directed trades. This means that directed-trade clients may receive worse prices than non-directed clients receive. Additionally, clients who direct trades to a particular broker or dealer often pay higher commissions, greater spreads, or receive less favorable net prices than they would if Boston Common were able to select brokers or dealers. Soft Dollars Boston Common may cause an advisory client’s account to pay a higher commission to a broker-dealer that provides brokerage and research services to the firm in a “soft-dollar” arrangement. It does this when it determines in good faith that the higher commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker. As noted above, in selecting brokers, Boston Common seeks brokerage services where the broker-dealer can provide value-added, company-specific, and thematic industry research, including meetings with management and conferences. However, it should be noted that where research products or services are provided through “soft dollar” arrangements, there is a conflict between Boston Common’s interests and its clients’ interests. This is because Boston Common does not have to pay for the research, research products and services which are paid for by soft-dollar credits generated by client transactions. This gives Boston Common an incentive to trade with particular brokers to obtain these products and services. Boston Common seeks to mitigate this conflict of interest by ranking the broker-dealers according to Page 32 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  established criteria. These rankings are reviewed by the Trading Committee, which determines how brokerage and soft dollars are allocated. In 2025, Boston Common used soft dollars to obtain third-party research and services including but not limited to information about the stock market, industry trends, company-specific information, market analyses, meetings with management and conferences. A particular client may not receive a direct benefit from Boston Common’s use of that client’s commission dollars to obtain soft dollar benefits. For example, a client invested solely in U.S. securities would not benefit from research on foreign markets that Boston Common obtained through soft dollars. Likewise, a client invested only in international securities would not benefit from research on U.S. markets obtained through soft dollars. Item 13: Review of Accounts Boston Common’s portfolio managers and analysts review advisory accounts for performance and consistency with the client’s investment strategy and objectives. Formal portfolio reviews occur every twelve to twenty-four months, but managers and analysts follow their clients’ accounts more frequently. In addition, the firm’s Investment team reviews client portfolios and holdings continuously to evaluate portfolio composition, industry status and risks, and consistency of the portfolio with the clients’ investment strategy and objectives. Significant market and political events, changes in an account’s investment goals and objectives, or other financial circumstances, may trigger an unscheduled review. In its weekly meetings, or on an ad hoc basis, the Investment Team will analyze the potential impact of significant events or review changes in the client’s objectives and take appropriate action. Boston Common’s sustainability research team conducts reviews of the holdings in client accounts on a quarterly basis to ensure compliance with applicable social guidelines. The sustainability team will also analyze the potential impact of any controversial news event or changes in a company’s environmental, social, or corporate governance record on an ad-hoc basis. This may trigger an unscheduled review of clients’ accounts to determine if investment action is required. Clients receive account statements directly from their custodians. In addition, Boston Common sends its clients written quarterly performance reports showing their accounts’ market value, asset allocation, and investment performance. In its account statements, Boston Common urges its clients compare the information in those quarterly reports to information received directly from the custodian of the client’s account. Page 33 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Item 14: Client Referrals and Other Compensation Referral Fees Disclosures Third-party solicitors are paid for client referrals. This creates a conflict of interest because the solicitor might refer a client to Boston Common in order to receive a fee from Boston Common, even if the firm’s advisory services were not as well suited for the client as another adviser might have been. As these situations represent a conflict of interest, Boston Common has established the following restrictions in order to ensure that it fulfills its fiduciary responsibilities to its clients:  All such referral fees are paid in accordance with the requirements of Rule 206(4)-3 of the Advisers Act and any corresponding state securities law requirements;  the solicitor, including If the client is introduced to Boston Common by an unaffiliated solicitor, the solicitor, at the time of the solicitation, will disclose the nature of the solicitor relationship and provide each prospective client with a copy of Boston Common’s Form ADV Part 2A and 3, if applicable, together with a copy of the written disclosure statement disclosing the terms of the solicitation arrangement between Boston Common and the compensation that the solicitor will receive from Boston Common; and  All referred clients are reviewed to ensure that Boston Common’s fees, services, and investment strategies are suitable for their investment needs and objectives. Item 15: Custody Boston Common does not maintain or accept actual custody of client funds or securities. Nonetheless, Boston Common is deemed to have “custody” of certain client accounts within the meaning of Rule 206(4)-2 under the Advisers Act (the “Rule”) because Boston Common directly deducts its fees or has authority to remit payments to third parties from these client accounts. Each client’s custodian sends the client periodic account statements (generally on a quarterly basis). Clients should contact Boston Common’s Portfolio Operations group, immediately at 617-720-5557 if they do not receive account statements from their custodian at least quarterly. Clients should compare their custodial statements with Boston Common’s reporting. Boston Common also has custody over certain client accounts within the meaning of the Rule because it has limited authority to withdraw or transfer Page 34 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  assets from these accounts. Ashland Partners & Company LLP, an independent auditor that is registered with, and subject to regular inspection by the Public Company Accounting Oversight Board, conducted an annual surprise audit of Boston Common in April of 2025 to determine whether it is complying with the Rule. Since Boston Common serves as managing member of private funds, and because it has the right to debit fees or withdraw assets directly from these private funds, Boston Common is deemed to have custody over the private funds within the meaning of the Rule. To comply with the Rule, Boston Common provides each investor in a private fund independently audited financial statements within 120 days following the private fund’s fiscal year end. Investors in the private funds who do not timely receive audited financial statements should contact Boston Common’s Chief Compliance Officer at 617-720-5557 promptly. Item 16: Investment Discretion Boston Common has discretionary authority over its clients’ accounts. This means that the firm, and not the client, decides which securities to buy and sell. Clients may not restrict Boston Common’s investment discretion, except in very limited instances in which the firm may take direction from a client to buy or sell a particular security, or not to do so. Before making decisions on a client’s behalf, Boston Common and the client enter into an investment management agreement in which the client gives Boston Common express permission to make investment decisions on the client’s behalf. If the client is an entity, as opposed to an individual, Boston Common requires documentation that the individual(s) executing the investment management agreement has the authority to act on the entity’s behalf. In rendering investment management and advisory services to various funds and separately managed accounts, the firm may give advice or take action with respect to investments in securities that are different from advice given to or action taken for other clients. Similarly-managed portfolios may have different performance results for a variety of reasons, including but not limited to, the timing of sales of securities, the use of directed brokerage, client instructions, tax considerations, or the holding of token positions for advocacy purposes, as described below. With client permission, Boston Common may maintain a token position of in a security in order to maintain an engagement position that the firm has taken on behalf of client shareholders. As a result, the performance of such a client’s account may differ from the accounts of otherwise similarly-managed clients. Page 35 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Item 17: Voting Client Securities Boston Common generally maintains the authority to vote client proxies as outlined in Rule 206(4) -6 under the Advisers Act. The firm votes proxies on behalf of clients who have not specifically decided to retain those responsibilities. The firm votes proxies for most accounts it manages directly, as well as proxies for accounts managed by its third-party sub-adviser. The firm votes foreign proxies. Clients may request documentation of how their proxies were voted by contacting Boston Common’s Chief Compliance Officer at 617-720-5557. As a registered investment adviser, Boston Common has a legal and fiduciary duty to act in the best interest of each client as determined, among other things, by the client’s investment objectives and the sustainability guidelines set out in the investment management agreement. As a sustainable investment adviser, the firm engages in shareholder activism on behalf of clients, which includes proposing shareholder resolutions or commenting on actions proposed by a company’s board of directors. It also engages in active dialogues with management on a variety of issues including environmental, social and corporate governance practices. The firm’s proxy voting guidelines are designed to promote, wherever possible, what the firm believes are the best global corporate governance practices. Among other things, these proxy guidelines advocate: increased board independence and diversity; transparency; and   disclosure;   management accountability to shareowners. The firm will generally oppose proposals that seek to expand the number of options, a repricing of options, or other actions that would, in the firm’s view, result in excessive dilution of common shares. There may be instances where the firm has a conflict of interest in voting proxies. This might happen, for example, if the company soliciting the proxy hires Boston Common as its investment adviser. A conflict could also arise if the client were a labor union whose position on a proposal was inconsistent with the interests of the company’s other shareholders. In the event of a conflict, Boston Common’s Investment team is consulted. Conflicts are also mitigated in that Boston Common has hired a third party proxy administrator, ISS, Inc., to vote proxies according to specific, pre-determined custom guidelines that have been set out by Boston Common. ISS provides consistent, across-the-board voting on issues pursuant to Boston Common’s custom guidelines, and the adherence to these positions prevents Boston Common from making case-by-case decisions. Page 36 Form ADV Part 2A: Investment Adviser Brochure Boston Common Asset Management, LLC  Boston Common does not commonly vote proxies for ERISA clients because plan fiduciaries usually retain this power. In the event the firm does vote proxies for an ERISA client, it will do so in the best financial interest of the ERISA client as required by ERISA. Due to these requirements, in performing proxy voting for ERISA plans, Boston Common may give less consideration to sustainability factors than it might when voting proxies for non-ERISA clients. Clients are generally not able to direct how Boston Common votes proxies; however clients are always entitled to see how their proxies have been voted by contacting the firm. A copy of Boston Common’s Proxy Policy and Procedures is available upon request by contacting Boston Common’s Chief Compliance Officer at 617- 720-5557. Item 18: Financial Information Pursuant to Rule 206(4)-4 under the Advisers Act, investment advisers are required to disclose certain financial information about their business practices that might be important to a client’s decision in choosing an investment adviser. As of the date of this filing, Boston Common does not have any financial hardships or other conditions that might impair its ability to meet its contractual obligations to clients. Boston Common does not require prepayment of more than $1,200 in fees from any client six months or more in advance.
