Investment Objective

The AMG FQ Long-Short Equity Fund's (the “Fund”) investment objective is to achieve long-term capital appreciation.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

	Class N	Class I
Management Fee	0.35%	0.35%
Distribution and Service (12b-1) Fees	0.25%	None
Other Expenses1	0.48%	0.40%
Total Annual Fund Operating Expenses	1.08%	0.75%
Fee Waiver and Expense Reimbursements2	(0.04)%	(0.04)%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursements2	1.04%	0.71%

¹ Expense information has been restated to reflect current fees.

² AMG Funds LLC (the “Investment Manager”) has contractually agreed, through at least March 1, 2019, to waive management fees and/or reimburse the Fund’s expenses in order to limit Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursements (exclusive of taxes, interest (including interest incurred in connection with bank and custody overdrafts), shareholder servicing fees, distribution and service (12b-1) fees, brokerage commissions and other transaction costs, acquired fund fees and expenses, and extraordinary expenses) of the Fund to the annual rate of 0.69% of the Fund’s average daily net assets, subject to later reimbursement by the Fund in certain circumstances. In general, for a period of up to 36 months, the Investment Manager may recover from the Fund fees waived and expenses paid pursuant to this contractual agreement, provided that such repayment would not cause the Fund’s Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursements (exclusive of the items noted in the parenthetical above) to exceed the contractual expense limitation amount. The contractual expense limitation may only be terminated in the event the Investment Manager or a successor ceases to be the investment manager of the Fund or a successor fund, by mutual agreement between the Investment Manager and the AMG Funds I Board of Trustees or in the event of the Fund’s liquidation unless the Fund is reorganized or is a party to a merger in which the surviving entity is successor to the accounting and performance information of the Fund.

Expense Example

This Example will help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The Example makes certain assumptions. It assumes that you invest $10,000 as an initial investment in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. It also assumes that your investment has a 5% total return each year and the Fund’s operating expenses remain the same. The Example includes the Fund’s contractual expense

limitation through March 1, 2019. Although your actual costs may be higher or lower, based on the above assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class N	$106	$337	$592	$1,314
Class I	$ 73	$233	$411	$ 924

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 178% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers located in the U.S. First Quadrant, L.P. (“First Quadrant” or the “Subadviser”) considers issuers to be located in the U.S. if they are organized in the U.S., have their principal place of business in the U.S., or their securities are traded principally in the U.S.

The Fund invests primarily in long and short equity positions in sectors, industries and companies based on First Quadrant’s assessment of relative attractiveness, which takes into account both growth and value characteristics. The Fund may invest in companies representing a broad range of market capitalizations, which generally may include small- and mid-capitalization companies. The Fund also may invest in securities issued by real estate investment trusts (“REITs”), other investment vehicles that invest in real estate or operating companies whose businesses relate to real estate. The Fund generally takes long positions in securities that the Subadviser believes will increase in value, and it may do this, for example, by purchasing the security outright. The Fund takes short positions in securities that the Subadviser believes will decrease in value. The Subadviser will vary the Fund’s long-short exposure over time based on the Subadviser’s assessment of market conditions and other factors. The Fund does not intend to be market neutral and anticipates that it will normally hold a higher percentage of its assets in long positions (i.e., the Fund will be “net long”). Downside risk is managed through a systematic portfolio

AMG FQ Long-Short Equity Fund SUMMARY PROSPECTUS

protection structure (an option overlay known as a “put/spread collar” strategy) and/or dynamic management of equity market exposure which is intended to reduce risk of the Fund in periods of market stress. When implementing the Fund’s investment strategy, the Subadviser typically uses sophisticated computer models to evaluate a broad universe of equity issuers.

The Fund may use derivatives, such as futures, swaps, options, and foreign currency forwards or futures for any reason, including to take long and short positions as a substitute for investing in conventional securities, enhance return, earn income, or reduce exposure to other risks. The Fund may also use derivatives to attempt to maintain exposure to the equity markets while holding cash for temporary liquidity needs.

Principal Risks

There is the risk that you may lose money on your investment. All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Below are some of the risks of investing in the Fund. The risks are described in alphabetical order and not in the order of importance or potential exposure.

Derivatives Risk—the use of derivatives involves costs, the risk that the value of derivatives may not correlate perfectly with their underlying assets, rates or indices, and the risk of mispricing or improper valuation. The use of derivatives may not succeed for various reasons, and the complexity and rapidly changing structure of derivatives markets may increase the possibility of market losses.

Growth Stock Risk—the prices of equity securities of companies that are expected to experience relatively rapid earnings growth, or “growth stocks,” may be more sensitive to market movements because the prices tend to reflect future investor expectations rather than just current profits.

Hedging Risk—there is no guarantee that hedging strategies will be successful. For example, changes in the value of a hedging transaction may not completely offset changes in the value of the assets and liabilities being hedged. Hedging transactions involve costs and may result in losses.

High Portfolio Turnover Risk—higher portfolio turnover may adversely affect Fund performance by increasing Fund transaction costs and may increase a shareholder’s tax liability.

Large-Capitalization Stock Risk—the stocks of large-capitalization companies are generally more mature and may not be able to reach the same levels of growth as the stocks of small- or mid-capitalization companies.

Leverage Risk—borrowing and some derivative investments such as futures and forward commitment transactions, may magnify smaller adverse market movements into relatively larger losses.

Management Risk—because the Fund is an actively managed investment portfolio, security selection or focus on securities in a particular style, market sector or group of companies may cause

the Fund to incur losses or underperform relative to its benchmarks or other funds with a similar investment objective. There can be no guarantee that the Subadviser’s investment techniques and risk analysis will produce the desired result.

Market Risk—market prices of investments held by the Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political, or market conditions or in response to events that affect particular industries or companies.

Model and Data Risk–when a quantitative model (“Model”) or information or data (“Data”) used in managing the Fund contains an error, or is incorrect or incomplete, any investment decision made in reliance on the Model or Data may not produce the desired results and the Fund may realize losses. In addition, any hedging based on a faulty Model or Data may prove to be unsuccessful. Furthermore, the success of a Model that is predictive in nature is dependent largely on the accuracy and reliability of the supplied historical data. All Models are susceptible to input errors or errors in design, which may cause the resulting output to be faulty.

Real Estate Industry Risk—investments in the Fund may be subject to many of the same risks as a direct investment in real estate. The stock prices of companies in the real estate industry, including REITs, are typically sensitive to changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, as well as the management skill and creditworthiness of the issuer.

Short Sales Risk—a short sale of a security involves the theoretical risk of unlimited loss because of potential unlimited increases in the market price of the security sold short. The Fund’s use of short sales, in certain circumstances, can result in significant losses.

Small- and Mid-Capitalization Stock Risk—the stocks of small- and mid-capitalization companies often have greater price volatility, lower trading volume, and less liquidity than the stocks of larger, more established companies.

Value Stock Risk—value stocks may perform differently from the market as a whole and may be undervalued by the market for a long period of time.

Performance

The following performance information illustrates the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s performance compares to that of a broad-based securities market index. The performance information for the Fund’s Class N shares (formerly Investor Class shares, which were renamed Class N shares on October 1, 2016 (formerly Class A shares, which were renamed Investor Class shares on December 1, 2012)) for periods prior to December 1, 2012, does not reflect the impact of the front-end and deferred sales charges (loads) that were in effect until December 1, 2012. Effective October 1, 2016, outstanding Institutional Class shares of the Fund were renamed Class I shares. Effective August 31, 2017, the Fund changed its name from “AMG FQ U.S. Equity Fund” to “AMG

Tax Information

The Fund intends to make distributions that are taxable to you as ordinary income, qualified dividend income or capital gains, except when your investment is in an IRA, 401(k), or other tax-advantaged investment plan. By investing in the Fund through such a plan, you will not be subject to tax on distributions from the Fund so long as the amounts distributed remain in the plan, but you will generally be taxed upon withdrawal of monies from the plan.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies, including the Investment Manager, AMG Distributors, Inc. (the “Distributor”) and the Subadviser, may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
