*   Applies only to certain redemptions of shares bought with no initial sales charge.

**   This charge is phased out over six years.

***   This charge is eliminated after one year.

†   Management fees reflect a performance adjustment. The fund’s base management fee is subject to adjustment, up or down, based on the fund’s performance relative to the performance of the MSCI ACWI ex USA Index (ND) for portions of a performance period after April 1, 2021 and the MSCI World Index (ND) for portions of a performance period prior to April 1, 2021. For the most recent fiscal year, the fund’s base management fee prior to any performance adjustment was 0.69%.

Example

The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year and that the fund’s operating expenses remain the same. Your actual costs may be higher or lower.

Share class	1 year	3 years	5 years	10 years
Class A	$684	$913	$1,161	$1,871
Class B	$691	$891	$1,216	$2,005
Class B (no redemption)	$191	$591	$1,016	$2,005
Class C	$291	$591	$1,016	$2,005
Class C (no redemption)	$191	$591	$1,016	$2,005
Class R	$140	$437	$755	$1,657
Class R6	$76	$237	$411	$918
Class Y	$90	$281	$488	$1,084

Portfolio turnover

The fund pays transaction-related costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or the above example, affect fund performance. The fund’s turnover rate in the most recent fiscal year was 62%.

Investments, risks, and performance

Investments

We invest mainly in common stocks (growth or value stocks or both) of companies of any size outside the United States that we believe have favorable investment potential. Under normal circumstances, we invest at least 80% of the fund’s net assets in equity investments. This policy may be changed only after 60 days’ notice to shareholders. The fund’s equity investments may include common stocks, preferred stocks, convertible securities, warrants, American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs). We invest in both developed countries and in emerging markets.

We may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments. We may also consider other factors that we believe will cause the stock price to rise. We may also use derivatives, such as futures, options, certain foreign currency transactions, warrants and swap contracts, for both hedging and non-hedging purposes.

The fund is “non-diversified,” which means it may invest a greater percentage of its assets in fewer issuers than a “diversified” fund. The fund expects to invest in a limited number of issuers.

Risks

It is important to understand that you can lose money by investing in the fund. The value of investments in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic, political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes, and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings. The novel coronavirus (COVID-19) pandemic and efforts to contain its spread are likely to negatively affect the value, volatility, and liquidity of the securities and other assets in which the fund invests and exacerbate other risks that apply to the fund. These effects could negatively impact the fund’s performance and lead to losses on your investment in the fund. Growth stocks may be more susceptible to earnings disappointments, and value stocks may fail to rebound or realize their potential. These risks are generally greater for small and midsize companies. The fund will be more susceptible to these risks than other funds because it invests in a limited number of issuers or sectors, and the fund may perform poorly as a result of adverse developments affecting those issuers or sectors.

The value of international investments traded in foreign currencies may be adversely impacted by fluctuations in exchange rates. International investments, particularly investments in emerging markets, may carry risks associated with potentially less stable economies or governments (such as the risk of seizure by a foreign government, the imposition of currency or other restrictions, or high levels of inflation), and may be or become illiquid.

Investments focused in a single region may be affected by common economic forces and other factors. In addition, events in any one country within the region may impact the other countries or the region as a whole. Because the fund currently invests, and

4          

may in the future invest, significantly in European and Asian companies, the fund is particularly susceptible to economic, political, regulatory and other events or conditions affecting issuers in Europe and Asia. European financial markets have in recent years experienced increased volatility due to concerns with some countries’ high levels of sovereign debt, budget deficits, and unemployment. Asia includes countries in various stages of economic development, from emerging market economies to the highly developed economy of Japan. Some parts of Asia may be subject to a greater degree of economic, political and social instability than is the case in the United States.

As a non-diversified fund, the fund invests in fewer issuers and is more vulnerable than a more broadly diversified fund to fluctuations in the values of the securities it holds.

Our use of derivatives may increase the risks of investing in the fund by increasing investment exposure (which may be considered leverage) or, in the case of many over-the-counter instruments, because of the potential inability to terminate or sell derivatives positions and the potential failure of the other party to the instrument to meet its obligations.

There is no guarantee that the investment techniques, analyses, or judgments that we apply in making investment decisions for the fund will produce the intended outcome or that the investments we select for the fund will perform as well as other securities that were not selected for the fund. We, or the fund’s other service providers, may experience disruptions or operating errors that could negatively impact the fund.

The fund may not achieve its goal, and it is not intended to be a complete investment program. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance

The performance information below gives some indication of the risks associated with an investment in the fund by showing the fund’s performance year to year and over time. Before April 1, 2021, the fund was managed with a materially different investment strategy and may have achieved materially different performance results under its current investment strategy from that shown for periods before this date. The bar chart does not reflect the impact of sales charges. If it did, performance would be lower. Please remember that past performance is not necessarily an indication of future results. Monthly performance figures for the fund are available at putnam.com.

Annual total returns for class A shares before sales charges

Average annual total returns after sales charges (for periods ended 12/31/20)

Share class	1 year	5 years	10 years
Class A before taxes	3.79%	8.24%	8.30%
Class A after taxes on distributions	3.65%	8.11%	8.16%
Class A after taxes on distributions and sale of fund shares	2.33%	6.47%	6.77%
Class B before taxes	4.25%	8.42%	8.29%
Class C before taxes	8.29%	8.71%	8.13%
Class R before taxes	9.81%	9.25%	8.67%
Class R6 before taxes*	10.49%	9.96%	9.36%
Class Y before taxes	10.35%	9.80%	9.21%
MSCI ACWI ex USA Index (ND)** (no deduction for fees, expenses or taxes, other than withholding taxes on reinvested dividends)	10.65%	8.93%	4.92%
MSCI World Index (ND)-MSCI ACWI ex USA Index (ND) Linked Benchmark*** (no deduction for fees, expenses or taxes, other than withholding taxes on reinvested dividends)	15.90%	12.19%	9.87%

*   Performance for class R6 shares prior to their inception (7/2/12) is derived from the historical performance of class Y shares and has not been adjusted for the lower investor servicing fees applicable to class R6 shares; had it, returns would have been higher.

**   As of April 1, 2021, the MSCI ACWI ex USA Index (ND) (an unmanaged index of equity securities from developed countries (excluding the United States) and emerging countries) replaced the MSCI World Index (ND) (an unmanaged index of equity securities from developed countries) as the benchmark for this fund because, in Putnam Management’s opinion, the securities tracked by the MSCI ACWI ex USA Index (ND) more accurately reflect the types of securities that generally will be held by the fund. The average annual total returns of the MSCI World Index (ND) for the one-year, five-year, and ten-year periods ended on December 31, 2020 were 15.90%, 12.19%, and 9.87%, respectively.

***   The MSCI World Index (ND)-MSCI ACWI ex USA Index (ND) Linked Benchmark represents performance of the MSCI World Index (ND) from the inception date of the fund, July 1, 1994, through March 31, 2021 and performance of the MSCI ACWI ex USA Index (ND) from April 1, 2021 forward.

After-tax returns reflect the historical highest individual federal marginal income tax rates and do not reflect state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are shown for class A shares only and will vary for other classes. These after-tax returns do not apply if you hold your fund shares through a 401(k) plan, an IRA, or another tax-advantaged arrangement.

Class B share performance reflects conversion to class A shares after eight years.

Effective March 1, 2021, Class C shares generally convert to Class A shares eight years after purchase. Prior to March 1, 2021, Class C shares generally converted to Class A shares ten years after purchase. Class C share performance does not reflect conversion to class A shares after eight years; had it, returns for the 10-year period would have been higher.

Tax information

The fund’s distributions will be taxed as ordinary income or capital gains unless you hold the shares through a tax-advantaged arrangement, in which case you will generally be taxed only upon withdrawal of monies from the arrangement.

Financial intermediary compensation

If you purchase the fund through a broker/dealer or other financial intermediary (such as a bank or financial professional), the fund and its related companies may pay that intermediary for the sale of fund shares and related services. Please bear in mind that these payments may create a conflict of interest by influencing the broker/dealer or other intermediary to recommend the fund over another investment. Ask your advisor or visit your advisor’s website for more information.
