HIGHLIGHTS • Natural resources stocks rose in the first half of 2016 against the backdrop of a strong bounce in prices for oil and many other commodities. • The New Era Fund returned 17.24% in the six months ended June 30, 2016, and significantly outpaced the S&P 500 Index and the Lipper Global Natural Resources Funds Average. • We believe that the commodity cycle entered a structural downturn in 2011. Technological innovation continues to compress energy costs, while loose monetary policies from global central banks are likely to prevent the appropriate cleansing mechanisms that would otherwise allow excess commodity capacity to fall away. • We continue to position the portfolio defensively and are looking for companies with low cost structures and healthy balance sheets that are more likely to survive the current challenges and emerge in a stronger competitive position when the cycle turns.

T. Rowe Price New Era Fund Manager’s Letter

Fellow Shareholders Natural resources stocks rallied in the first six months of 2016 after a dismal second half of 2015. A number of factors played a role in the rebound, including economic stimulus in China, oil supply outages, a healthier high yield bond market, and a modestly weaker dollar. In the oil sector, optimism about the potential for several major oil-producing countries to agree on a production freeze served as the initial spark for a rally that pushed prices back toward $50 per barrel. (Oil prices discussed in this letter are for West Texas Intermediate, or WTI, unless otherwise noted.) Production outages in Canada, Nigeria, Ghana, and Brazil; better-than-expected demand; and optimism about supply/demand “rebalancing” in the latter half of the year were also supportive. In the natural gas space, a collapse in rig counts and improved demand after a weak winter have helped prices regain some footing. As shown in the Performance Comparison table, your fund returned Six-Month Period Ended 6/30/16 Total Return 17.24% for the six-month New Era Fund 17.24% reporting period ended New Era Fund–I Class 17.35 June 30, 2016. (Returns S&P 500 Index 3.84 for the I Class shares differ slightly due to their Lipper Global Natural Resources Funds Average 12.86 different fee structure.) The fund significantly outperformed the broad market S&P 500 Index and the Lipper Global Natural Resources Funds Average of similarly managed funds. Please note that we changed the fund’s secondary benchmark from the Lipper Global Natural Resources Funds Index to the Lipper Global Natural Resources Funds Average. The P erformance C omparison

Lipper index was recently reduced to an aggregation of 10 underlying natural resources mutual funds, after previously comprising 30 such funds. We believe that the Lipper Global Natural Resources Average, which includes the entire category of similarly managed funds, is a more appropriate comparison of the broad universe of competitors for the T. Rowe Price New Era Fund. We actively accumulated oversold energy and metals equities and certain high yield instruments in the late stages of 2015’s downturn, but the amplitude of 2016’s rally has been a bit of a surprise. Our decisions to overweight and underweight underlying industries boosted performance versus our Lipper benchmark, led by overweights to construction materials and multi-utilities. Stock selection detracted from relative results, due in part to our refining and oil services stocks. MARKET ENVIRONMENT

As with recent shareholder letters, I plan to spend some time discussing our views on oil. In short, we continue to believe that we are in the midst of a long-term bear market in oil prices, which should average approximately $45 to $50 per barrel—if not less— for the next decade. This is not to say that oil will not rise above this price periodically along the way. In fact, we expect cyclical rallies to carry oil above the $45 to $50 range, not unlike previous rallies between 1986 and 1999 in the depressed period after the last significant supply shock. However, we believe upside surprises in productivity, something we discussed at length in our last shareholder letter, will quickly snuff out rallies above this trend line. In any event, these rallies serve to test the oil industry’s ability to sustain this productivity. At some point, productivity—the ease with which a barrel of oil can be found and produced—will stabilize and even reverse as it did between 1999 and 2011. In our opinion, this would mark a sustained rise in oil prices as costs steepen and would shape the next bull market for oil. Even during 2016’s recent rally, we saw evidence of a long period of weak fundamentals for oil. In the U.S., for example, previously shuttered oil rigs started to come back on line as WTI prices approached $50 per barrel—something we call “incentive pricing.”

We do not even view the current rally as cyclical in nature. In other words, there is no fundamental reason why oil should be at or near incentive pricing given the vast amounts of crude inventory and the ongoing oversupply situation we see extending into 2017. There are going to be long periods of time in a bear market when 4

the cyclical outlook and the structural outlook are consistent. This is one such time. As such, we continue to position our portfolio defensively by investing in companies with strong balance sheets, low-cost commodity producers, and companies offering attractive dividend yields. PORTFOLIO REVIEW AND POSITIONING

Stocks in commodity-related industries reacted favorably as prices found a bottom and, in many instances, rallied throughout the first half of 2016. As mentioned previously, we believe this is due to a variety of factors, including early optimism that several oil producers, led by Saudi Arabia and Russia, would freeze production. Supply disruptions and optimistic views on the future of the global supply/demand relationship added to the rally. With a few exceptions, we believe the bulk of these moves were driven by sentiment rather than fundamentals. Overall, we have a structurally defensive posture with a focus on strong balance sheets and low costs. Low-cost oil exploration and production companies in the Permian Basin continue to represent a significant area of focus for the fund and were strong contributors in the first half of 2016. Among these stocks were Concho Resources, Cimarex Energy, Matador Resources, Diamondback Energy, Occidental Petroleum, and Pioneer Natural Resources. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.) We also have a significant position in North American natural gas producers. We think that natural gas prices reached unsustainably low levels in the first half of 2016, which appropriately chased rigs and capital away from the industry. These stocks were strong performers in the first half of the year, and we are optimistic about continued price appreciation in the second half from names such as EQT, Tourmaline Oil, Gulfport Energy, NRG Energy and ARC Resources. Construction materials companies, including Vulcan Materials and Martin Marietta Materials, also were among the top contributors for the period amid improvements in U.S. construction markets. In addition, investors are becoming more optimistic about the potential for a new U.S. presidential administration to renew fiscal stimulus measures in 2017.

Our metals and mining stocks helped the fund’s absolute performance in the first half of 2016, but an underweight position versus the Lipper benchmark detracted from relative results. The collapse in real interest rates in the U.S. helped fuel a gain of roughly 25% in gold prices and drove an I ndustry D iversification even more sizable gain in gold-related equities, Metals and Other and including Randgold Mining Reserves 9% 11% Resources, OceanaGold, Franco-Nevada, Exploration Utilities and Production 10% Centamin, and Fresnillo. 22%

We Based on net assets as of 6/30/16. became further disenchanted with this area of energy as the oil glut turned into a refined products glut. We expect this environment to persist until refiners eventually cave in and cut back on operational capacity. Although we currently do not own a refining stock in the portfolio, we do own Murphy USA. A strong performer during our reporting period, Murphy is a convenience store chain that benefits from low fuel prices and higher consumer disposable income. Energy Industrials 10%

Our utility stocks generated robust absolute gains for the period as long-term interest rates fell to new lows. We continue to view these stocks favorably relative to their commodity-producing peers and have an overweight position versus our Lipper benchmark. We expect this to be the case for a considerable period. We do not see inflation as a medium-term threat given the high debt loads of Western economies, and we expect long-term interest rates to remain relatively low despite the likelihood of higher short-term rates as the Federal Reserve normalizes its rate policy, which could potentially resume in the latter half of 2016. As a result, valuations still look attractive for certain

utilities stocks, particularly when compared with other yield-oriented investment options in the market. Furthermore, we expect some utilities to benefit from low natural gas prices and/or “trapped gas” resulting from a shortage of infrastructure. NiSource, which recently spun off its midstream assets into Columbia Pipeline, was one such stock that contributed favorably to performance in the first half of 2016. We subsequently exited our position in Columbia Pipeline but maintained our position in NiSource. We also benefited from a position in Atmos Energy, a Texas natural gas utility that also plays on this theme. OUTLOOK

As we have written in previous shareholder letters, we believe that we are in the initial years of a secular downcycle in commodities. U.S. oil prices are now down over 50% from their peak a few years ago, and U.S. natural gas prices have fallen by almost 80% since 2008. Although cheaper energy benefits U.S. consumers’ budgets and energy-intensive manufacturers, it challenges Most of the the stocks of energy producers, particularly energy service companies. Falling oil prices have also punished factors that energy-exporting economies in the developing world contributed to the and affected the U.S. high yield bond market, which has a high percentage of energy-related issuers. steep fall in oil Most of the factors that contributed to the steep fall in oil prices since the latter half of 2014 remain in place latter half of 2014 while new factors have emerged. The shale oil revolution has changed the face of the competitive dynamics remain in place… in the oil industry and has had a profound impact on cost curves across the entire commodity complex. We believe the extraordinarily high inventory in the oil supply chain will take much longer to work off than most experts are predicting, especially if the market pushes into incentive pricing (above $50 per barrel) too soon. We believe these factors will ultimately prove to be structural rather than cyclical, resulting in long-term deflation to the cost curve that may feel permanent to many market participants. Our forecast is that long-term oil prices will average below most market participants’ forecasts and the current oil futures curve. prices since the

7

Regardless of the challenging environment, we remain committed to our bottom-up stock selection process and our philosophy of buying and holding a diverse selection of fundamentally sound natural resources companies with solid balance sheets and talented management. Despite the potential for near-term challenges, we believe the market will reward our consistent, disciplined investment approach over the long term. Respectfully submitted,

R isks of S tock I nvesting The fund’s share price can fall because of weakness in the stock markets, a particular industry, or specific holdings. Stock markets can decline for many reasons, including adverse political or economic developments, changes in investor psychology, or heavy institutional selling. The prospects for an industry or company may deteriorate because of a variety of factors, including disappointing earnings or changes in the competitive environment. In addition, the investment manager’s assessment of companies held in a fund may prove incorrect, resulting in losses or poor performance even in rising markets. Funds that invest only in specific industries will experience greater volatility than funds investing in a broad range of industries. The rate of earnings growth of natural resources companies may be irregular since these companies are strongly affected by natural forces, global economic cycles, and international politics. For example, stock prices of energy companies can fall sharply when oil prices fall.

The expense ratio shown is as of the fund’s fiscal year ended 12/31/15. This number may vary from the expense ratio shown elsewhere in this report because it is based on a different time period and, if applicable, includes acquired fund fees and expenses but does not include fee or expense waivers.

F und E xpense E xample As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to 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 most recent six-month period and held for the entire period. Please note that the fund has two share classes: The original share class (Investor Class) charges no distribution and service (12b-1) fee, and the I Class shares are also available to institutionally oriented clients and impose no 12b-1 or administrative fee payment. Each share class is presented separately in the table. Actual Expenses The first line of the following table (Actual) provides information about actual account values and expenses based on the fund’s actual returns. You may use the information on this line, together with your account balance, 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 on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

T. Rowe Price New Era Fund

F und E xpense E xample ( continued ) Note: T. Rowe Price charges an annual account service fee of $20, generally for accounts with less than $10,000. The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $50,000 or more; accounts electing to receive electronic delivery of account statements, transaction confirmations, prospectuses, and shareholder reports; or accounts of an investor who is a T. Rowe Price Preferred Services, Personal Services, or Enhanced Personal Services client (enrollment in these programs generally requires T. Rowe Price assets of at least $100,000). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

N otes to F inancial S tatements

T. Rowe Price New Era Fund, Inc. (the fund), is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end management investment company. The fund seeks to provide long-term capital growth primarily through the common stocks of companies that own or develop natural resources and other basic commodities, and also through the stocks of selected nonresource growth companies. The fund has two classes of shares: the New Era Fund original share class, referred to in this report as the Investor Class, incepted on January 20, 1969, and the New Era Fund–I Class (I Class), incepted on December 17, 2015. I Class shares generally are available only to investors meeting a $1,000,000 minimum investment or certain other criteria. Each class has exclusive voting rights on matters related solely to that class; separate voting rights on matters that relate to both classes; and, in all other respects, the same rights and obligations as the other class. Note 1 - Significant Accounting Policies Basis of Preparation  The fund is an investment company and follows accounting

and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 (ASC 946). The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including, but not limited to, ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale or maturity. Investment Transactions, Investment Income, and Distributions  Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions, if any, are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions from REITs are initially recorded as dividend income and, to the extent such

30

T. Rowe Price New Era Fund

represent a return of capital or capital gain for tax purposes, are reclassified when such information becomes available. Income distributions are declared and paid by each class annually. Distributions to shareholders are recorded on the ex-dividend date. Capital gain distributions, if any, are generally declared and paid by the fund annually. Currency Translation  Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollar values each day at the prevailing exchange rate, using the mean of the bid and asked prices of such currencies against U.S. dollars as quoted by a major bank. Purchases and sales of securities, income, and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is reflected as a component of security gains and losses. Class Accounting  Shareholder servicing, prospectus, and shareholder report

expenses incurred by each class are charged directly to the class to which they relate. Expenses common to both classes, investment income, and realized and unrealized gains and losses are allocated to the classes based upon the relative daily net assets of each class. Rebates  Subject to best execution, the fund may direct certain security trades to brokers who have agreed to rebate a portion of the related brokerage commission to the fund in cash. Commission rebates are reflected as realized gain on securities in the accompanying financial statements and totaled $54,000 for the six months ended June 30, 2016. In-Kind Subscriptions  Under certain circumstances, and when considered to be in the best interest of all shareholders, the fund may accept portfolio securities rather than cash as payment for the purchase of fund shares (in-kind subscription). For financial reporting and tax purposes, the cost basis of contributed securities is equal to the market value of the securities on the date of contribution. In-kind subscriptions result in no gain or loss and no tax consequences for the fund. During the six months ended June 30, 2016, the fund accepted $26,974,000 of in-kind subscriptions.

Note 2 - VALUATION

The fund’s financial instruments are valued and each class’s net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business. 31

T. Rowe Price New Era Fund

Fair Value  The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) has been established by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the Board and has representation from legal, portfolio management and trading, operations, risk management, and the fund’s treasurer.

Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value: Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads) Level 3 – unobservable inputs Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial 32

T. Rowe Price New Era Fund

instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values. Valuation Techniques  Equity securities listed or regularly traded on a securities exchange or in the over-the-counter (OTC) market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made. OTC Bulletin Board securities are valued at the mean of the closing bid and asked prices. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the closing bid and asked prices for domestic securities and the last quoted sale or closing price for international securities.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted to reflect the fair value of such securities at the close of the NYSE. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, in its judgment, materially affect the value of some or all of its portfolio securities, the fund will adjust the previous quoted prices to reflect what it believes to be the fair value of the securities as of the close of the NYSE. In deciding whether it is necessary to adjust quoted prices to reflect fair value, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. The fund uses outside pricing services to provide it with quoted prices and information to evaluate or adjust those prices. The fund cannot predict how often it will use quoted prices and how often it will determine it necessary to adjust those prices to reflect fair value. As a means of evaluating its security valuation process, the fund routinely compares quoted prices, the next day’s opening prices in the same markets, and adjusted prices. Actively traded equity securities listed on a domestic exchange generally are categorized in Level 1 of the fair value hierarchy. Non-U.S. equity securities generally are categorized in Level 2 of the fair value hierarchy despite the availability of quoted prices because, as described above, the fund evaluates and determines whether those quoted prices reflect fair value at the close of the NYSE or require adjustment. OTC Bulletin Board securities, certain preferred securities, and equity securities traded in inactive markets generally are categorized in Level 2 of the fair value hierarchy. 33

T. Rowe Price New Era Fund

Debt securities generally are traded in the OTC market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Generally, debt securities are categorized in Level 2 of the fair value hierarchy. Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value. Thinly traded financial instruments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded. Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of an equity investment with limited market activity, such as a private placement or a thinly traded public company stock, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, new rounds of financing, negotiated transactions of significant size between other investors in the company, relevant market valuations of peer companies, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants, transaction information can be reliably obtained, and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as market-based valuation multiples; a discount or premium from 34

market value of a similar, freely traded security of the same issuer; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue. Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.

Note 3 - OTHER Investment Transactions

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information. Restricted Securities  The fund may invest in securities that are subject to legal or contractual restrictions on resale. Prompt sale of such securities at an acceptable price may be difficult and may involve substantial delays and additional costs. Bank Loans  The fund may invest in bank loans, which represent an interest in amounts owed by a borrower to a syndication of lenders. Bank loans are generally noninvestment grade and often involve borrowers whose financial condition is troubled or highly leveraged. Bank loans may be in the form of either assignments or participations. A loan assignment transfers all legal, beneficial, and economic rights to the buyer, and transfer typically requires consent of both the borrower and agent. In contrast, a loan participation generally entitles the buyer to receive the cash flows from principal, interest, and any fee payments; however, the seller continues to hold legal title to the loan. As a result, the buyer of a loan participation generally has no direct rights against the borrower and is exposed to credit risk of both the borrower and seller of the participation. Bank loans often have extended settlement periods, usually may be repaid at any time at the option of the borrower, and may require additional principal to be funded at the borrowers’ discretion at a later date (unfunded commitments). Until settlement, the fund maintains liquid assets sufficient to settle its unfunded loan commitments. The fund reflects both the funded portion of a bank loan as well as its unfunded commitment in the Portfolio of Investments. However, to the extent a credit agreement provides no initial funding of a tranche and funding of the full commitment at a future date(s) is at the borrower’s discretion and considered uncertain, no loan is reflected in the Portfolio of Investments until paid. Other  Purchases and sales of portfolio securities other than short-term

securities aggregated $1,242,323,000 and $1,156,800,000, respectively, for the six months ended June 30, 2016.

Note 4 - Federal Income Taxes

No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences. The amount and character of tax-basis distributions and composition of net assets are finalized at fiscal year-end; accordingly, tax-basis balances have not been determined as of the date of this report. The fund intends to retain realized gains to the extent of available capital loss carryforwards. Net realized capital losses may be carried forward indefinitely to offset future realized capital gains. As of December 31, 2015, the fund had $315,418,000 of available capital loss carryforwards. At June 30, 2016, the cost of investments for federal income tax purposes was $2,754,930,000. Net unrealized gain aggregated $535,768,000 at period-end, of which $679,485,000 related to appreciated investments and $143,717,000 related to depreciated investments. Note 5 - related Party Transactions

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). The investment management agreement between the fund and Price Associates provides for an annual investment management fee, which is computed daily and paid monthly. The fee consists of an individual fund fee, equal to 0.25% of the fund’s average daily net assets, and a group fee. The group fee rate is calculated based on the combined net assets of certain mutual funds sponsored by Price Associates (the group) applied to a graduated fee schedule, with rates ranging from 0.48% for the first $1 billion of assets to 0.270% for assets in excess of $500 billion. The fund’s group fee is determined by applying the group fee rate to the fund’s average daily net assets. At June 30, 2016, the effective annual group fee rate was 0.29%.

37

T. Rowe Price New Era Fund

The I Class is subject to an operating expense limitation (I Class limit) pursuant to which Price Associates is contractually required to pay all operating expenses of the I Class, excluding management fees, interest, borrowing-related expenses, taxes, brokerage commissions, and extraordinary expenses, to the extent such operating expenses, on an annualized basis, exceed 0.05% of average net assets. This agreement will continue until April 30, 2018, and may be renewed, revised or revoked only with approval of the fund’s Board. The I Class is required to repay Price Associates for expenses previously paid to the extent the class’s net assets grow or expenses decline sufficiently to allow repayment without causing the class’s operating expenses to exceed the I Class limit. However, no repayment will be made more than three years after the date of a payment or waiver. For the six months ended June 30, 2016, the I Class operated below its expense limitation. In addition, the fund has entered into service agreements with Price Associates and two wholly owned subsidiaries of Price Associates (collectively, Price). Price Associates provides certain accounting and administrative services to the fund. T. Rowe Price Services, Inc., provides shareholder and administrative services in its capacity as the fund’s transfer and dividend-disbursing agent. T. Rowe Price Retirement Plan Services, Inc., provides subaccounting and recordkeeping services for certain retirement accounts invested in the Investor Class and I Class. For the six months ended June 30, 2016, expenses incurred pursuant to these service agreements were $23,000 for Price Associates; $833,000 for T. Rowe Price Services, Inc.; and $48,000 for T. Rowe Price Retirement Plan Services, Inc. The total amount payable at period-end pursuant to these service agreements is reflected as Due to Affiliates in the accompanying financial statements, if any. The fund may invest in the T. Rowe Price Reserve Investment Fund, the T. Rowe Price Government Reserve Investment Fund, or the T. Rowe Price Short-Term Reserve Fund (collectively, the Price Reserve Investment Funds), open-end management investment companies managed by Price Associates and considered affiliates of the fund. The Price Reserve Investment Funds are offered as short-term investment options to mutual funds, trusts, and other accounts managed by Price Associates or its affiliates and are not available for direct purchase by members of the public. The Price Reserve Investment Funds pay no investment management fees.

The fund may participate in securities purchase and sale transactions with other funds or accounts advised by Price Associates (cross trades), in accordance with procedures adopted by the fund’s Board and Securities and Exchange Commission rules, which require, among other things, that such purchase and sale cross trades be effected at the independent current market price of the security.During the six months ended June 30, 2016, the aggregate value of purchases and sales cross trades with other funds or accounts advised by Price Associates was less than 1% of the fund’s net assets as of June 30, 2016.

T. Rowe Price New Era Fund

A pproval of I nvestment M anagement A greement On March 11, 2016, the fund’s Board of Directors (Board), including a majority of the fund’s independent directors, approved the continuation of the investment management agreement (Advisory Contract) between the fund and its investment advisor, T. Rowe Price Associates, Inc. (Advisor). In connection with its deliberations, the Board requested, and the Advisor provided, such information as the Board (with advice from independent legal counsel) deemed reasonably necessary. The Board considered a variety of factors in connection with its review of the Advisory Contract, also taking into account information provided by the Advisor during the course of the year, as discussed below: Services Provided by the Advisor The Board considered the nature, quality, and extent of the services provided to the fund by the Advisor. These services included, but were not limited to, directing the fund’s investments in accordance with its investment program and the overall management of the fund’s portfolio, as well as a variety of related activities such as financial, investment operations, and administrative services; compliance; maintaining the fund’s records and registrations; and shareholder communications. The Board also reviewed the background and experience of the Advisor’s senior management team and investment personnel involved in the management of the fund, as well as the Advisor’s compliance record. The Board concluded that it was satisfied with the nature, quality, and extent of the services provided by the Advisor. Investment Performance of the Fund The Board reviewed the fund’s three-month, one-year, and year-by-year returns, as well as the fund’s average annualized total returns over the 3-, 5-, and 10-year periods, and compared these returns with a wide variety of comparable performance measures and market data, including those supplied by Lipper and Morningstar, which are independent providers of mutual fund data. On the basis of this evaluation and the Board’s ongoing review of investment results, and factoring in the relative market conditions during certain of the performance periods, the Board concluded that the fund’s performance was satisfactory. Costs, Benefits, Profits, and Economies of Scale The Board reviewed detailed information regarding the revenues received by the Advisor under the Advisory Contract and other benefits that the Advisor (and its affiliates) may have realized from its relationship with the fund, including any research received under “soft dollar” agreements and commission-sharing arrangements with broker-dealers. The Board considered that the Advisor may receive some benefit from soft-dollar arrangements pursuant to which research is received from broker-dealers that execute the applicable fund’s portfolio transactions. The Board received information on the estimated costs incurred and profits realized by the Advisor from managing T. Rowe Price mutual funds. The Board also reviewed estimates of the profits realized from managing the fund in particular, and the Board concluded that the Advisor’s profits were reasonable in light of the services provided to the fund.

41

T. Rowe Price New Era Fund

A pproval of I nvestment M anagement A greement ( continued ) The Board also considered whether the fund benefits under the fee levels set forth in the Advisory Contract from any economies of scale realized by the Advisor. Under the Advisory Contract, the fund pays a fee to the Advisor for investment management services composed of two components—a group fee rate based on the combined average net assets of most of the T. Rowe Price mutual funds (including the fund) that declines at certain asset levels and an individual fund fee rate based on the fund’s average daily net assets—and the fund pays its own expenses of operations (subject to an expense limitation on operating expenses with respect to the I Class). The Board concluded that the advisory fee structure for the fund continued to provide for a reasonable sharing of benefits from any economies of scale with the fund’s investors. Fees The Board was provided with information regarding industry trends in management fees and expenses, and the Board reviewed the fund’s management fee rate, operating expenses, and total expense ratio (for the Investor Class and I Class) in comparison with fees and expenses of other comparable funds based on information and data supplied by Lipper. The information provided to the Board indicated that the fund’s management fee rate was above the median for certain groups of comparable funds and at or below the median for other groups of comparable funds. The information also indicated that the total expense ratio for the Investor Class was above the median for certain groups of comparable funds and at or below the median for other groups of comparable funds, and the total expense ratio for the I Class was below the median for comparable funds. The Board also reviewed the fee schedules for institutional accounts (including subadvised mutual funds) and private accounts with similar mandates that are advised or subadvised by the Advisor and its affiliates. Management provided the Board with information about the Advisor’s responsibilities and services provided to subadvisory and other institutional account clients, including information about how the requirements and economics of the institutional business differ from those of the Advisor’s proprietary mutual fund business. The Board considered information showing that the Advisor’s proprietary mutual fund business is generally more complex from a business and compliance perspective than its institutional account business and considered various other relevant factors, including the broader scope of operations and oversight, more extensive shareholder communication infrastructure, greater asset flows, heightened business risks, and differences in applicable laws and regulations associated with the Advisor’s proprietary mutual fund business. In assessing the reasonableness of the fund’s management fee rate, the Board considered the differences in the nature of the services required for the Advisor to manage its proprietary mutual fund business versus managing a discrete pool of assets as a subadvisor to another institution’s mutual fund or for another institutional account and the degree to which the Advisor performs significant additional services and assumes greater risk in managing the fund and other T. Rowe Price mutual funds than it does for institutional account clients.

42

T. Rowe Price New Era Fund

A pproval of I nvestment M anagement A greement ( continued ) On the basis of the information provided and the factors considered, the Board concluded that the fees paid by the fund under the Advisory Contract are reasonable. Approval of the Advisory Contract As noted, the Board approved the continuation of the Advisory Contract. No single factor was considered in isolation or to be determinative to the decision. Rather, the Board concluded, in light of a weighting and balancing of all factors considered, that it was in the best interests of the fund and its shareholders for the Board to approve the continuation of the Advisory Contract (including the fees to be charged for services thereunder). The independent directors were advised throughout the process by independent legal counsel.
