The Growth Fund of America^®   Annual report
for the year ended
August 31, 2018

We believe in
discovering long-term
growth opportunities
around the world on
behalf of our investors.

The Growth Fund of America seeks to provide you with growth of capital.

This fund is one of more than 40 offered by Capital Group, home of American Funds, one of the nation’s largest mutual fund families. For more than 85 years, Capital Group has invested with a long-term focus based on thorough research and attention to risk.

Fund results shown in this report, unless otherwise indicated, are for Class A shares at net asset value. If a sales charge (maximum 5.75%) had been deducted, the results would have been lower. Results are for past periods and are not predictive of results for future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. Investing for short periods makes losses more likely. For current information and month-end results, visit americanfunds.com.

Here are the average annual total returns on a $1,000 investment with all distributions reinvested for periods ended September 30, 2018 (the most recent calendar quarter-end):

Class A shares	1 year	5 years	10 years
Reflecting 5.75% maximum sales charge	15.30%	13.20%	11.71%

For other share class results, visit americanfunds.com and americanfundsretirement.com.

The total annual fund operating expense ratio is 0.62% for Class A shares as of the prospectus dated November 1, 2018 (unaudited).

Investment results assume all distributions are reinvested and reflect applicable fees and expenses. When applicable, investment results reflect fee waivers, without which results would have been lower. Visit americanfunds.com for more information.

Investing outside the United States involves risks, such as currency fluctuations, periods of illiquidity and price volatility, as more fully described in the prospectus. These risks may be heightened in connection with investments in developing countries. Refer to the fund prospectus and the Risk Factors section of this report for more information on these and other risks associated with investing in the fund.

Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.

Fellow investors:

Buoyed by strong equity markets around the globe, The Growth Fund of America (GFA) returned 23.49% for the fiscal year ended August 31, 2018. This return includes a dividend payment of 25 cents a share during the period, as well as a onetime capital gains distribution of just over $3.23 a share.

By way of comparison, the unmanaged Standard & Poor’s 500 Composite Index, a market capitalization-weighted index based on the results of approximately 500 widely held common stocks, gained 19.66% over the same period. The fund’s return also surpassed that of two of the four Lipper peer indexes commonly used in comparisons.

As you can see in the table below, the fund’s long-term results continue to surpass the fund’s primary index benchmark and are comparable to its peers. As we’ve done for decades, we remain committed to the value of long-term investing, and we encourage our investors and their financial advisors to take a similar approach in working toward their financial goals.

Compared with the S&P 500 Index as a percent of net assets.

Netflix, returning 110.45%. On the other hand, semiconductor manufacturer Broadcom, the fund’s 10th-largest holding, declined 13.11%.

It’s worth noting that the fund’s top five holdings — Amazon, Alphabet (Google), Netflix, Facebook and Microsoft — are among the leading companies in the information technology and consumer discretionary sectors, and represent a large share of the fund’s total assets. While we are aware of the potential concerns of this concentration in a group of stocks that have already done well, we currently remain comfortable with these companies’ fundamentals and opportunities for continued growth.

Overall, consumer discretionary shares helped the fund’s returns, while energy stocks and certain financials, particularly those related to mortgage lending, held back results for the period compared to the benchmark index.

Roughly 10.9% of the fund’s holdings were based overseas, and another 7.4% were held in cash and short-term securities, leaving about 81.7% in domestic equities. These percentages aren’t predetermined, but rather reflect the managers’ best thinking about individual equities, no matter where they reside. The fund’s cash holdings allow managers to take advantage of potential investment opportunities as they arise, and can provide a buffer against volatility and uncertain markets as well.

The road ahead

The markets over the past year were largely driven by very strong earnings from large U.S. corporations, helped along by a growing economy, federal tax cuts and lessened government regulations across a number of industries. All these factors have combined to boost investor confidence, and have overshadowed the potential negative impacts of global trade disputes and geopolitical upheavals.

We continue to monitor and analyze the evolving trade tensions between the United States and the rest of the world, for better and for worse, and the political issues these can create. As of this writing, we do not believe these concerns will assert themselves over more positive market fundamentals — but would caution that the landscape for both continues to shift rapidly.

It seems rational to assume we’re in the later innings of a record-setting (by length of time) economic expansion and bull market — but as baseball fans know, sometimes ballgames can last a long time. We will continue to monitor both economic and political news, and adjust accordingly, but we also remain committed to our continued search for potential long-term investments on behalf of our shareholders. Our robust research-driven process has stood the test of time, and we believe it can continue to help long-term shareholders meet their financial goals.

We thank you, as always, for your continued support of The Growth Fund of America, and look forward to reporting to you in six months.

Cordially,

The value of a long-term perspective

Fund results shown are for Class A shares and reflect deduction of the maximum sales charge of 5.75% on the $10,000 investment.¹ Thus, the net amount invested was $9,425.² Results are for past periods and are not predictive of results for future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. For current information and month-end results, visit americanfunds.com.

The results shown are before taxes on fund distributions and sale of fund shares.

1	As outlined in the prospectus, the sales charge is reduced for accounts (and aggregated investments) of $25,000 or more and is eliminated for purchases of $1 million or more. There is no sales charge on dividends or capital gain distributions that are reinvested in additional shares.
2	The maximum initial sales charge was 8.5% prior to July 1, 1988.
3	Includes reinvested dividends of $163,923 and reinvested capital gain distributions of $1,173,171.
4	The S&P 500 is unmanaged and, therefore, has no expenses. Investors cannot invest directly in an index. S&P 500 source: S&P Dow Jones Indices LLC.
5	Results of the Lipper Growth Funds Index do not reflect any sales charges. Lipper indexes track the largest mutual funds (no more than 30), represented by one share class per fund, in the corresponding Lipper category. Lipper source: Thomson Reuters Lipper.
6	Computed from data supplied by the U.S. Department of Labor, Bureau of Labor Statistics.

How a $10,000 investment has grown

While notable for their volatility in recent years, financial markets have tended to reward investors over the long term. Active management — bolstered by experience and careful research — can add even more value. As the chart shows, over its lifetime, The Growth Fund of America has done demonstrably better than its relevant benchmark.

Notes to financial statements

1. Organization

The Growth Fund of America (the “fund”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide growth of capital.

The fund has 19 share classes consisting of six retail share classes (Classes A, C, T, F-1, F-2 and F-3), five 529 college savings plan share classes (Classes 529-A, 529-C, 529-E, 529-T and 529-F-1) and eight retirement plan share classes (Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6). The 529 college savings plan share classes can be used to save for college education. The retirement plan share classes are generally offered only through eligible employer-sponsored retirement plans. The fund’s share classes are described further in the following table:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Classes A and 529-A	Up to 5.75%	None (except 1% for certain redemptions within 18 months of purchase without an initial sales charge)	None
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	Class 529-C converts to Class 529-A after 10 years*
Class 529-E	None	None	None
Classes T and 529-T†	Up to 2.50%	None	None
Classes F-1, F-2, F-3 and 529-F-1	None	None	None
Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6	None	None	None

*	Effective December 1, 2017.
†	Class T and 529-T shares are not available for purchase.

Holders of all share classes have equal pro rata rights to the assets, dividends and liquidation proceeds of the fund. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses (“class-specific fees and expenses”), primarily due to different arrangements for distribution, transfer agent and administrative services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each share class.

2. Significant accounting policies

The fund is an investment company that applies the accounting and reporting guidance issued in Topic 946 by the U.S. Financial Accounting Standards Board. The fund’s financial statements have been prepared to comply with U.S. generally accepted accounting principles (“U.S. GAAP”). These principles require the fund’s investment adviser to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. Subsequent events, if any, have been evaluated through the date of issuance in the preparation of the financial statements. The fund follows the significant accounting policies described in this section, as well as the valuation policies described in the next section on valuation.

Security transactions and related investment income — Security transactions are recorded by the fund as of the date the trades are executed with brokers. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. In the event a security is purchased with a delayed payment date, the fund will segregate liquid assets sufficient to meet its payment obligations. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis. Market discounts, premiums and original issue discounts on fixed-income securities are amortized daily over the expected life of the security.

Class allocations — Income, fees and expenses (other than class-specific fees and expenses) and realized and unrealized gains and losses are allocated daily among the various share classes based on their relative net assets. Class-specific fees and expenses, such as distribution, transfer agent and administrative services, are charged directly to the respective share class.

Dividends and distributions to shareholders — Dividends and distributions to shareholders are recorded on the ex-dividend date.

12 The Growth Fund of America

Currency translation — Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars at the exchange rates supplied by one or more pricing vendors on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the exchange rates on the dates of such transactions. The effects of changes in exchange rates on investment securities are included with the net realized gain or loss and net unrealized appreciation or depreciation on investments in the fund’s statement of operations. The realized gain or loss and unrealized appreciation or depreciation resulting from all other transactions denominated in currencies other than U.S. dollars are disclosed separately.

3. Valuation

Capital Research and Management Company (“CRMC”), the fund’s investment adviser, values the fund’s investments at fair value as defined by U.S. GAAP. The net asset value of each share class of the fund is generally determined as of approximately 4:00 p.m. New York time each day the New York Stock Exchange is open.

Methods and inputs — The fund’s investment adviser uses the following methods and inputs to establish the fair value of the fund’s assets and liabilities. Use of particular methods and inputs may vary over time based on availability and relevance as market and economic conditions evolve.

Equity securities are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Fixed-income securities, including short-term securities, are generally valued at prices obtained from one or more pricing vendors. Vendors value such securities based on one or more of the inputs described in the following table. The table provides examples of inputs that are commonly relevant for valuing particular classes of fixed-income securities in which the fund is authorized to invest. However, these classifications are not exclusive, and any of the inputs may be used to value any other class of fixed-income security.

Fixed-income class	Examples of standard inputs
All	Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data (collectively referred to as “standard inputs”)
Corporate bonds & notes; convertible securities	Standard inputs and underlying equity of the issuer
Bonds & notes of governments & government agencies	Standard inputs and interest rate volatilities

When the fund’s investment adviser deems it appropriate to do so (such as when vendor prices are unavailable or deemed to be not representative), fixed-income securities will be valued in good faith at the mean quoted bid and ask prices that are reasonably and timely available (or bid prices, if ask prices are not available) or at prices for securities of comparable maturity, quality and type.

Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are generally valued in the manner described for either equity or fixed-income securities, depending on which method is deemed most appropriate by the fund’s investment adviser.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the fund’s investment adviser are fair valued as determined in good faith under fair valuation guidelines adopted by authority of the fund’s board of trustees as further described. The investment adviser follows fair valuation guidelines, consistent with U.S. Securities and Exchange Commission rules and guidance, to consider relevant principles and factors when making fair value determinations. The investment adviser considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; significant events occurring after the close of trading in the security; and changes in overall market conditions. In addition, the closing prices of equity securities that trade in markets outside U.S. time zones may be adjusted to reflect significant events that occur after the close of local trading but before the net asset value of each share class of the fund is determined. Fair valuations and valuations of investments that are not actively trading involve judgment and may differ materially from valuations that would have been used had greater market activity occurred.

The Growth Fund of America 13

Processes and structure — The fund’s board of trustees has delegated authority to the fund’s investment adviser to make fair value determinations, subject to board oversight. The investment adviser has established a Joint Fair Valuation Committee (the “Fair Valuation Committee”) to administer, implement and oversee the fair valuation process, and to make fair value decisions. The Fair Valuation Committee regularly reviews its own fair value decisions, as well as decisions made under its standing instructions to the investment adviser’s valuation teams. The Fair Valuation Committee reviews changes in fair value measurements from period to period and may, as deemed appropriate, update the fair valuation guidelines to better reflect the results of back testing and address new or evolving issues. The Fair Valuation Committee reports any changes to the fair valuation guidelines to the board of trustees. The fund’s board and audit committee also regularly review reports that describe fair value determinations and methods.

The fund’s investment adviser has also established a Fixed-Income Pricing Review Group to administer and oversee the fixed-income valuation process, including the use of fixed-income pricing vendors. This group regularly reviews pricing vendor information and market data. Pricing decisions, processes and controls over security valuation are also subject to additional internal reviews, including an annual control self-evaluation program facilitated by the investment adviser’s compliance group.

Classifications — The fund’s investment adviser classifies the fund’s assets and liabilities into three levels based on the inputs used to value the assets or liabilities. Level 1 values are based on quoted prices in active markets for identical securities. Level 2 values are based on significant observable market inputs, such as quoted prices for similar securities and quoted prices in inactive markets. Certain securities trading outside the U.S. may transfer between Level 1 and Level 2 due to valuation adjustments resulting from significant market movements following the close of local trading. Level 3 values are based on significant unobservable inputs that reflect the investment adviser’s determination of assumptions that market participants might reasonably use in valuing the securities. The valuation levels are not necessarily an indication of the risk or liquidity associated with the underlying investment. For example, U.S. government securities are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market. The following table presents the fund’s valuation levels as of August 31, 2018 (dollars in thousands):

* Securities with a value of $12,348,595,000, which represented 6.23% of the net assets of the fund, transferred from Level 2 to Level 1 since the prior fiscal year-end, primarily due to a lack of significant market movements following the close of local trading.

4. Risk factors

Investing in the fund may involve certain risks including, but not limited to, those described below.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline — sometimes rapidly or unpredictably — due to various factors, including events or conditions affecting the general economy or particular industries; overall market changes; local, regional or global political, social or economic instability; governmental or governmental agency responses to economic conditions; and currency exchange rate, interest rate and commodity price fluctuations.

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives.

14 The Growth Fund of America

Investing in growth-oriented stocks — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments.

Investing outside the U.S. — Securities of issuers domiciled outside the U.S., or with significant operations or revenues outside the U.S., may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers operate or generate revenue. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as the imposition of price controls or punitive taxes, that could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the U.S. Investments outside the U.S. may also be subject to different accounting practices and different regulatory, legal and reporting standards and practices, and may be more difficult to value, than those in the U.S. In addition, the value of investments outside the U.S. may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund. The risks of investing outside the U.S. may be heightened in connection with investments in emerging markets.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the investment adviser in this process may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

5. Taxation and distributions

Federal income taxation — The fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and intends to distribute substantially all of its net taxable income and net capital gains each year. The fund is not subject to income taxes to the extent such distributions are made. Therefore, no federal income tax provision is required.

As of and during the period ended August 31, 2018, the fund did not have a liability for any unrecognized tax benefits. The fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statement of operations. During the period, the fund did not incur any significant interest or penalties.

The fund’s tax returns are not subject to examination by federal, state and, if applicable, non-U.S. tax authorities after the expiration of each jurisdiction’s statute of limitations, which is generally three years after the date of filing but can be extended in certain jurisdictions.

Non-U.S. taxation — Dividend and interest income are recorded net of non-U.S. taxes paid. The fund may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. As a result of rulings from European courts, the fund filed for additional reclaims related to prior years. These reclaims are recorded when the amount is known and there are no significant uncertainties on collectability. Gains realized by the fund on the sale of securities in certain countries, if any, may be subject to non-U.S. taxes. If applicable, the fund records an estimated deferred tax liability based on unrealized gains to provide for potential non-U.S. taxes payable upon the sale of these securities.

Distributions — Distributions paid to shareholders are based on net investment income and net realized gains determined on a tax basis, which may differ from net investment income and net realized gains for financial reporting purposes. These differences are due primarily to different treatment for items such as currency gains and losses; short-term capital gains and losses; capital losses related to sales of certain securities within 30 days of purchase; unrealized appreciation of certain investments in securities outside the U.S.; cost of investments sold and income on certain investments. The fiscal year in which amounts are distributed may differ from the year in which the net investment income and net realized gains are recorded by the fund for financial reporting purposes. The fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.

During the year ended August 31, 2018, the fund reclassified $187,000 from undistributed net investment income to capital paid in on shares of beneficial interest, $26,167,000 from undistributed net realized gain to undistributed net investment income and $869,551,000 from undistributed net realized gain to capital paid in on shares of beneficial interest to align financial reporting with tax reporting.

6. Fees and transactions with related parties

CRMC, the fund’s investment adviser, is the parent company of American Funds Distributors,^® Inc. (“AFD”), the principal underwriter of the fund’s shares, and American Funds Service Company^® (“AFS”), the fund’s transfer agent. CRMC, AFD and AFS are considered related parties to the fund.

Investment advisory services — The fund has an investment advisory and service agreement with CRMC that provides for monthly fees accrued daily. These fees are based on a series of decreasing annual rates beginning with 0.500% on the first $1 billion of average daily net assets and decreasing to 0.233% on such assets in excess of $210 billion. For the year ended August 31, 2018, the investment advisory services fee was $488,852,000, which was equivalent to an annualized rate of 0.267% of average daily net assets.

16 The Growth Fund of America

Class-specific fees and expenses — Expenses that are specific to individual share classes are accrued directly to the respective share class. The principal class-specific fees and expenses are further described below:

Distribution services — The fund has plans of distribution for all share classes, except Class F-2, F-3, R-5E, R-5 and R-6 shares. Under the plans, the board of trustees approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.25% to 1.00% as noted in this section. In some cases, the board of trustees has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes with a plan may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities.

Share class	Currently approved limits			Plan limits
Class A		0.25	%		0.25	%
Class 529-A		0.25			0.50
Classes C, 529-C and R-1		1.00			1.00
Class R-2		0.75			1.00
Class R-2E		0.60			0.85
Classes 529-E and R-3		0.50			0.75
Classes T, F-1, 529-T, 529-F-1 and R-4		0.25			0.50

For Class A and 529-A shares, distribution-related expenses include the reimbursement of dealer and wholesaler commissions paid by AFD for certain shares sold without a sales charge. These share classes reimburse AFD for amounts billed within the prior 15 months but only to the extent that the overall annual expense limits are not exceeded. As of August 31, 2018, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A shares.

Transfer agent services — The fund has a shareholder services agreement with AFS under which the fund compensates AFS for providing transfer agent services to each of the fund’s share classes. These services include recordkeeping, shareholder communications and transaction processing. In addition, the fund reimburses AFS for amounts paid to third parties for performing transfer agent services on behalf of fund shareholders.

Administrative services — The fund has an administrative services agreement with CRMC under which the fund compensates CRMC for providing administrative services to Class A, C, T, F, 529 and R shares. Administrative services are provided by CRMC to help assist third parties providing non-distribution services to fund shareholders. These services include providing in depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders. The agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of 0.05% of average daily net assets for all share classes. Currently Class A shares pay an annual fee of 0.01% of average daily net assets (which could be increased as noted above) and Class C, T, F, 529 and R shares pay an annual fee of 0.05% of their respective average daily net assets.

529 plan services — Each 529 share class is subject to service fees to compensate the Virginia College Savings Plan (“Virginia529”) for its oversight and administration of the CollegeAmerica 529 college savings plan. The fee is based on the combined net assets invested in Class 529 and ABLE shares of the American Funds. Class ABLE shares are offered on other American Funds by Virginia529 through ABLEAmerica, a tax-advantaged savings program for individuals with disabilities. The quarterly fee is based on a series of decreasing annual rates beginning with 0.10% on the first $20 billion of the combined net assets invested in the American Funds and decreasing to 0.03% on such assets in excess of $100 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 and ABLE shares of the American Funds for the last month of the prior calendar quarter. The fee is included in other expenses in the fund’s statement of operations. Virginia529 is not considered a related party to the fund.

* Amount less than one thousand.

Trustees’ deferred compensation — Trustees who are unaffiliated with CRMC may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the fund, are treated as if invested in shares of the fund or other American Funds. These amounts represent general, unsecured liabilities of the fund and vary according to the total returns of the selected funds. Trustees’ compensation of $1,437,000 in the fund’s statement of operations reflects $496,000 in current fees (either paid in cash or deferred) and a net increase of $941,000 in the value of the deferred amounts.

Affiliated officers and trustees — Officers and certain trustees of the fund are or may be considered to be affiliated with CRMC, AFD and AFS. No affiliated officers or trustees received any compensation directly from the fund.

Security transactions with related funds — The fund may purchase from, or sell securities to, other funds managed by CRMC (or funds managed by certain affiliates of CRMC) under procedures adopted by the fund’s board of trustees. The funds involved in such transactions are considered related by virtue of having a common investment adviser (or affiliated investment advisers), common trustees and/or common officers. When such transactions occur, each transaction is executed at the current market price of the security and no brokerage commissions or fees are paid in accordance with Rule 17a-7 of the 1940 Act.

Interfund lending — Pursuant to an exemptive order issued by the SEC, the fund, along with other CRMC-managed funds (or funds managed by certain affiliates of CRMC), may participate in an interfund lending program. The program provides an alternate credit facility that permits the funds to lend or borrow cash for temporary purposes directly to or from one another, subject to the conditions of the exemptive order. The fund did not lend or borrow cash through the interfund lending program at any time during the year ended August 31, 2018.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of The Growth Fund of America:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of The Growth Fund of America (the “Fund”), including the summary investment portfolio, as of August 31, 2018, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of August 31, 2018, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of August 31, 2018, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Expense example unaudited

As a fund shareholder, you incur two types of costs: (1) transaction costs, such as initial sales charges on purchase payments and contingent deferred sales charges on redemptions (loads), and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund so you can compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period (March 1, 2018, through August 31, 2018).

Actual expenses:

The first line of each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses paid during period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes:

The second line of each share class in the table on the following page provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio for the share class and an assumed rate of return of 5.00% per year before expenses, which is not the actual return of the share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5.00% hypothetical example with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F-1, F-2, F-3 and 529-F-1 shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would be lower by the amount of these fees.

Note that the expenses shown in the table on the following page are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Approval of Investment Advisory and Service Agreement

The Growth Fund of America’s board has approved the fund’s Investment Advisory and Service Agreement (the “agreement”) with Capital Research and Management Company (“CRMC”) for an additional one-year term through November 30, 2019. The board approved the agreement following the recommendation of the fund’s Contracts Committee (the “committee”), which is composed of all of the fund’s independent board members. The board and the committee determined in the exercise of their business judgment that the fund’s advisory fee structure was fair and reasonable in relation to the services provided, and that approving the agreement was in the best interests of the fund and its shareholders.

In reaching this decision, the board and the committee took into account information furnished to them throughout the year and otherwise provided to them, as well as information prepared specifically in connection with their review of the agreement, and were advised by their independent counsel. They considered the following factors, among others, but did not identify any single issue or particular piece of information that, in isolation, was the controlling factor, and each board and committee member did not necessarily attribute the same weight to each factor.

1. Nature, extent and quality of services

The board and the committee considered the depth and quality of CRMC’s investment management process, including its global research capabilities; the experience, capability and integrity of its senior management and other personnel; the low turnover rates of its key personnel; the overall financial strength and stability of CRMC and the Capital Group organization; the resources and systems CRMC devotes to investment management, compliance, trading, portfolio accounting and other services; and the ongoing evolution of CRMC’s organizational structure designed to maintain and strengthen these qualities. The board and the committee also considered the nature, extent and quality of administrative, compliance and shareholder services provided by CRMC to the fund under the agreement and other agreements, as well as the benefits to fund shareholders from investing in a fund that is part of a large family of funds. The board and the committee concluded that the nature, extent and quality of the services provided by CRMC have benefited and should continue to benefit the fund and its shareholders.

2. Investment results

The board and the committee considered the investment results of the fund in light of its objective to provide growth of capital. They compared the fund’s investment results with those of other funds (including funds that currently form the basis of the Lipper index for the category in which the fund is included), and data such as relevant market and fund indexes, over various periods through March 31, 2018. This report, including the letter to shareholders and related disclosures, contains certain information about the fund’s investment results. The board and the committee reviewed the fund’s investment results measured against various indexes, including the Lipper Growth Funds Index, the Lipper Large-Cap Core Funds Index, the Lipper Large-Cap Growth Funds Index and Standard & Poor’s 500 Composite Index. They reviewed the results for the one-year, three-year, five-year, 10-year, 20-year and lifetime periods, and placing greater emphasis on longer term periods. They noted that the investment results of the fund generally compared favorably to or in line with the results of these indexes for all time periods. The board and the committee concluded that the fund’s investment results have been satisfactory for renewal of the agreement, and that CRMC’s record in managing the fund indicated that its continued management should benefit the fund and its shareholders.

3. Advisory fees and total expenses

The board and the committee compared the advisory fees and total expense levels of the fund to those of other relevant funds. They observed that the fund’s advisory fees and expenses generally compared favorably to those of other similar funds included in the Lipper Growth Funds category. The board and the committee also considered the breakpoint discounts in the fund’s advisory fee structure that reduce the level of fees charged by CRMC to the fund as fund assets increase. In addition, they reviewed information regarding the effective advisory fees charged to non-mutual fund clients by CRMC and its affiliates. They noted that, to the extent there were differences between the advisory fees paid by the fund and the advisory fees paid by those clients, the differences appropriately reflected the investment, operational, regulatory and market differences between advising the fund and the other clients. The board and the committee concluded that the fund’s cost structure was fair and reasonable in relation to the services provided, and that the fund’s shareholders receive reasonable value in return for the advisory fees and other amounts paid to CRMC by the fund.

32 The Growth Fund of America

4. Ancillary benefits

The board and the committee considered a variety of other benefits that CRMC and its affiliates receive as a result of CRMC’s relationship with the fund and other American Funds, including fees for administrative services provided to certain share classes; fees paid to CRMC’s affiliated transfer agent; sales charges and distribution fees received and retained by the fund’s principal underwriter, an affiliate of CRMC; and possible ancillary benefits to CRMC and its institutional management affiliates in managing other investment vehicles. The board and the committee reviewed CRMC’s portfolio trading practices, noting the benefits CRMC receives from the research obtained with commissions from portfolio transactions made on behalf of the fund. The board and the committee took these ancillary benefits into account in evaluating the reasonableness of the advisory fees and other amounts paid to CRMC by the fund.

5. Adviser financial information

The board and the committee reviewed information regarding CRMC’s costs of providing services to the American Funds, including personnel, systems and resources of investment, compliance, trading, accounting and other administrative operations. They considered CRMC’s costs and related cost allocation methodology as well as its willingness to invest in technology, infrastructure and staff to maintain and expand services and capabilities, respond to industry and regulatory developments, and attract and retain qualified personnel. They noted information regarding the compensation structure for CRMC’s investment professionals. They reviewed information on the profitability of the investment adviser and its affiliates. The board and the committee also compared CRMC’s profitability and compensation data to the reported results and data of several large, publicly held investment management companies. The board and the committee noted the competitiveness and cyclicality of both the mutual fund industry and the capital markets, and the importance in that environment of CRMC’s long-term profitability for maintaining its independence, company culture and management continuity. They further considered the breakpoint discounts in the fund’s advisory fee structure and CRMC’s sharing of potential economies of scale, or efficiencies, through breakpoints and other fee reductions and costs voluntarily absorbed. The board and the committee concluded that the fund’s advisory fee structure reflected a reasonable sharing of benefits between CRMC and the fund’s shareholders.

The Capital Advantage^®

Since 1931, American Funds by Capital Group has helped investors pursue long-term investment success. Our consistent approach — in combination with The Capital System^SM — has resulted in a superior long-term track record.

Aligned with investor success

We base our decisions on a long-term perspective, which we believe aligns our goals with the interests of our clients. Our portfolio managers average 27 years of investment experience, including 22 years at our company, reflecting a career commitment to our long-term approach.¹

The Capital System

The Capital System combines individual accountability with teamwork. Funds using The Capital System are divided into portions that are managed independently by investment professionals with diverse backgrounds, ages and investment approaches. An extensive global research effort is the backbone of our system.

American Funds’ superior long-term track record

Equity funds have beaten their Lipper peer indexes in 92% of 10-year periods and 99% of 20-year periods. Fixed income funds have beaten their Lipper indexes in 77% of 10-year periods and 80% of 20-year periods.² Fund management fees have been among the lowest in the industry.³

1	Portfolio manager experience as of December 31, 2017.
2	Based on Class F-2 share results for rolling periods through December 31, 2017. Periods covered are the shorter of the fund’s lifetime or since the comparable Lipper index inception date (except Capital Income Builder and SMALLCAP World Fund, for which the Lipper average was used). Expenses differ for each share class, so results will vary. Class F-2 shares were first offered on August 1, 2008. Class F-2 share results prior to the date of first sale are hypothetical based on Class A share results without a sales charge, adjusted for typical estimated expenses. Results for certain funds with an inception date after August 1, 2008, also include hypothetical returns because those funds’ Class F-2 shares sold after the funds’ date of first offering. Please see americanfunds.com for more information on specific expense adjustments and the actual dates of first sale.
3	On average, our management fees were in the lowest quintile 71% of the time, based on the 20-year period ended December 31, 2017, versus comparable Lipper categories, excluding funds of funds.

ITEM 2 – Code of Ethics

The Registrant has adopted a Code of Ethics that applies to its Principal Executive Officer and Principal Financial Officer. The Registrant undertakes to provide to any person without charge, upon request, a copy of the Code of Ethics. Such request can be made by calling 800/421-4225 or to the Secretary of the Registrant, 6455 Irvine Center Drive, Irvine, California 92618.

ITEM 3 – Audit Committee Financial Expert

The Registrant’s board has determined that Linda Griego, a member of the Registrant’s audit committee, is an “audit committee financial expert” and "independent," as such terms are defined in this Item. This designation will not increase the designee’s duties, obligations or liability as compared to his or her duties, obligations and liability as a member of the audit committee and of the board, nor will it reduce the responsibility of the other audit committee members. There may be other individuals who, through education or experience, would qualify as "audit committee financial experts" if the board had designated them as such. Most importantly, the board believes each member of the audit committee contributes significantly to the effective oversight of the Registrant’s financial statements and condition.

The committee will not delegate its responsibility to pre-approve these services to the investment adviser. The committee may delegate to one or more committee members the authority to review and pre-approve audit and permissible non-audit services.  Actions taken under any such delegation will be reported to the full committee at its next meeting. The pre-approval requirement is waived with respect to non-audit services if certain conditions are met. The pre-approval requirement was not waived for any of the non-audit services listed above provided to the Registrant, adviser and affiliates.

The non-audit services represented by these amounts were brought to the attention of the committee and considered to be compatible with maintaining the auditors’ independence.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INVESTMENT PORTFOLIO

To the Shareholders and Board of Trustees of The Growth Fund of America:

Opinion on the Investment Portfolio

We have audited the accompanying investment portfolio of The Growth Fund of America (the “Fund”), as of August 31, 2018, and the related notes (“investment portfolio”) (included in Item 6 of this Form N-CSR). In our opinion, the investment portfolio presents fairly, in all material respects, the investments in securities of the Fund as of August 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

The investment portfolio is the responsibility of the Fund’s management. Our responsibility is to express an opinion on the investment portfolio based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the investment portfolio is free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the investment portfolio, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the investment portfolio. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the investment portfolio. We believe that our audit provides a reasonable basis for our opinion.

ITEM 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 8 – Portfolio Managers of Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 9 – Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 10 – Submission of Matters to a Vote of Security Holders

There have been no material changes to the procedures by which shareholders may recommend nominees to the Registrant’s board of trustees since the Registrant last submitted a proxy statement to its shareholders. The procedures are as follows. The Registrant has a nominating and governance committee comprised solely of persons who are not considered ‘‘interested persons’’ of the Registrant within the meaning of the Investment Company Act of 1940, as amended. The committee periodically reviews such issues as the board’s composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of trustees. While the committee normally is able to identify from its own resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the board. Such suggestions must be sent in writing to the nominating and governance committee of the Registrant, c/o the Registrant’s Secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the nominating and governance committee.

ITEM 11 – Controls and Procedures

(a)

The Registrant’s Principal Executive Officer and Principal Financial Officer have concluded, based on their evaluation of the Registrant’s disclosure controls and procedures (as such term is defined in Rule 30a-3 under the Investment Company Act of 1940), that such controls and procedures are adequate and reasonably designed to achieve the purposes described in paragraph (c) of such rule.

(b)

Effective May 28, 2018, the The Growth Fund of America’s investment adviser implemented a new fixed income order management, trading, and compliance system.  In connection with introducing this new system, additional automated and manual controls were implemented and some existing controls were modified.  None of these changes were in response to any identified deficiency or weakness in the The Growth Fund of America’s internal control over financial reporting.

ITEM 12 – Exhibits

(a)(1)	The Code of Ethics that is the subject of the disclosure required by Item 2 is attached as an exhibit hereto.
(a)(2)	The certifications required by Rule 30a-2 of the Investment Company Act of 1940 and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are attached as exhibits hereto.
