Mangan Wealth Management, Inc. was founded in 2005 and became a state registered investment advisory firm in 2007 and is principally controlled by the sole shareholder, Rick Mangan. We offer clients portfolio management where we utilize modern portfolio theory to develop passive asset allocated portfolios. We also offer financial planning to help clients budget, manage cash needs, and educational funding analysis. Another service we offer is pension consulting for small business to establish a Self Employed Pension (SEP IRA) plan. Our outlook has been derived through extensive research of financial history, which is melded with proprietary fundamental and technical analysis giving us an unique view of the financial landscape. As an independent Registered Investment Advisor, Mangan Wealth Management, Inc. is free to recommend any publicly available investments, and can tailor portfolios to the specific needs of the client based on input most relevant to each individual client. Furthermore, all client accounts are managed on a discretionary basis and are individually segregated in the client’s own name at the brokerage firm acting as custodian for the account. This structure helps all clients maintain the safeguards of the custodial brokerage institution while simultaneously helping to ensure that Mangan Wealth Management, Inc. has access to make discretionary decisions of how the client’s funds will be utilized. We offer personalized and ongoing discretionary advice and management for your employer’s defined contribution (DC) plan, using the available investment options through your plan. We will trade your account on an ongoing and periodical basis as outlined in the Investment Policy Statement/Consulting Services Agreement. As all clients have unique tax implications, risk tolerances, time horizons, and personal biases, maintaining individual accounts on a discretionary basis helps to align each client’s unique financial situation with the outlook of Mangan Wealth Management, Inc.

Fees are typically billed on a quarterly basis, in advance of the quarter, in the amount of ¼ of the agreed upon annual rate. In almost all cases, the quarterly fee is debited directly from the client's investment account(s), although in unique situations, the client could be billed directly. While the ultimate fees paid to Mangan Wealth Management, Inc. are determined between both Mangan Wealth Management, Inc. and the client in a mutual agreement, the following fee grid provides our published rates: Minimum Fee: $4,000 annually Annual Fee of 1.00% for assets under $500,000 Annual Fee of 0.85% for assets of $500,001 to $3,000,000 Annual Fee of 0.60% for assets of $3,000,001 to $6,000,000 Annual Fee of 0.35% for assets of $6,000,001 and above In all instances, the Adviser will send the client a written invoice, including the fee, the formula used to calculate the fee, the fee calculation itself, the time period covered by the fee, and, if applicable, the amount of assets under management on which the fee was based and the name of the custodian(s) on your fee invoice. The Adviser will send these to the client concurrent with the request for payment or payment of the Adviser’s advisory fees.

Should Mangan Wealth Management, Inc. or the client wish to terminate the contract before the quarter has ended, Mangan Wealth Management, Inc. will refund the pro-rata amount of quarterly fees based on the number of days remaining in the quarter. Mangan Wealth Management, Inc. has no proprietary products, does not accept third party fees for referrals or recommendations of client assets, receives no commissions, mutual fund 12(b)-1 fees, or is in any other way compensated for any reason other than the fee disclosed to clients as billed based on the assets under management.

(Please see “Brokerage Practices” on page 5 for more information about this.) Item 6 - Performance-Based Fees and Side-By-Side Management Mangan Wealth Management, Inc. does not have any conflicts of interest arising from performance-based fees or side-by-side management arrangements. 5  Item 7 - Types of Clients Mangan Wealth Management, Inc. primarily provides advice to individuals. We consider our customer service and focus on performance as second to none. In an effort to maintain these standards, we typically request a household account minimum of $400,000. Item 8 - Methods of Analysis, Investment Strategies, and Risk of Loss Investing in securities and the financial markets in general involves risk. No method of investing can be deemed “safe” through all financial markets, as capital loss, default risk, and risk to purchasing power (inflation) all pose significant risks in different market environments. Mangan Wealth Management, Inc. attempts to mitigate these risks by evaluating where each broad asset class resides within the larger secular market cycle and relative to historical valuations. This proprietary analysis, based on a study of financial history, is used to help determine the general valuation risk level of each broad asset class within the confines of the entire portfolio. ERISA / IRC Fiduciary Acknowledgment. When Mangan Wealth Management provides investment advice to a client regarding the client’s retirement plan account or individual retirement account, it does so as a fiduciary within the meaning of Title I of the Employee Retirement Income Security Act (“ERISA”) and/or the Internal Revenue Code (“IRC”), as applicable, which are laws governing retirement accounts. The way Mangan Wealth Management makes money creates some conflicts with client interests, so Mangan Wealth Management complies with impartial conducts standards that requires it to act in the client’s best interest and not put its interests ahead of the clients. Under the impartial conducts standards, Mangan Wealth Management must: • Meet a professional standard of care when making investment recommendations (give prudent advice); • Never put its financial interests ahead of the client’s when making recommendations (give loyal advice); • Avoid misleading statements about conflicts of interest, fees, and investments; • Follow policies and procedures designed to ensure that Mangan Wealth Management gives advice that is in the client’s best interest; • Charge no more than is reasonable for Mangan Wealth Management services; and • Give the client basic information about conflicts of interest.

Item 9 - Disciplinary Information Neither Rick Mangan nor Mangan Wealth Management, Inc. has ever been the subject of any legal or disciplinary event relating to the business of investment advisor. There is nothing material to disclose for any client or prospective client to evaluate in this regard. 6  Item 10 - Other Financial Industry Activities and Affiliations Rick Mangan and Mangan Wealth Management, Inc. provide CPA services. Item 11 - Code of Ethics, Participation or Interest in Client Transactions and Personal Trading As Rick Mangan and Mangan Wealth Management, Inc. firmly believe in the advice offered to clients, we often invest in the same (or related) securities as those recommended to clients. To overcome any conflicts of interest due to price fills, Mangan Wealth Management, Inc. makes every effort to aggregate prices of the transaction (on the same day, for the same security, at or about the same time) to ensure that all parties receive the same price. However, trades cannot always be executed at the same time or even on the same side of the market. Unique financial circumstances may cause the same or similar securities to be bought or sold regardless of the near-term outlook recommended by Mangan Wealth Management, Inc. In all such cases, every trade is pre-allocated for the specific individual client account to ensure that the price they receive is the price relevant to their specific trade. Mangan Wealth Management, Inc. makes every effort to avoid all potential conflicts of interest. By aggregating trades for multiple accounts on the same transaction, or (when necessary) pre-allocating all other trades that are account specific, Mangan Wealth Management, Inc. avoids any such conflicts or preferential treatment.
