Despite strong fourth-quarter performance, the broad market produced minimal gains for the second half and the year ended December 31, 2015. However, growth stocks performed better than both value stocks and the S&P 500 Index throughout 2015. Our results for the last six months and the full year exceeded all of the relevant broad market benchmarks by substantial margins. Several of our large holdings in the consumer discretionary, health care, and information technology sectors generated strong contributions.

The Blue Chip Growth Fund returned 4.38% for the last six months and 11.15% for the year ended December 31, 2015, outperforming its benchmark, the S&P 500 Index; the Lipper peer group; and the Russell large-cap, growth-specific index. As shown in the Growth of $10,000 chart on page 16, the fund has outpaced the S&P 500 and the Lipper index by a significant margin over the last 10 years. (Returns for the Advisor and R Class shares were slightly lower, reflecting their different fee structures.)

Your fund continued to compare favorably with its competitors over the long term. Lipper ranked the Blue Chip Growth Fund in the top decile of its large-cap growth funds universe for the 1-, 3-, 5-, and 10-year periods ended December 31, 2015. (Based on cumulative total return, Lipper ranked the Blue Chip Growth Fund 37 of 668, 20 of 615, 10 of 545, and 34 of 389 funds for the 1-, 3-, 5-, and 10-year periods ended December 31, 2015, respectively. Past performance cannot guarantee future results.)

Recent volatility in global financial markets reinforces the view that many of the challenges that have concerned investors have not been resolved. Despite a year of solid U.S. employment gains and signs of improvement in job growth in several developed markets, investors have remained concerned about the breadth and sustainability of global economic growth. The sharp decline in oil and other commodity prices has helped consumers, but it has created stress for energy producers and related industries.

Rising concern about growth in several sectors, particularly in energy and commodities, led to steep losses in the high yield bond market. Energy is the largest component of the domestic high yield market. The decline in the high yield market is noteworthy because it has sometimes presaged broader economic slowdowns. Stress in debt markets and widening credit spreads generally result in tighter credit conditions, which can also contribute to additional economic weakness.

China’s economy has slowed. Some of the weakness has been the result of a deliberate effort to transition from a manufacturing- and export-based economy to one that emphasizes services and domestic consumption. However, the transition cannot be managed seamlessly and has led to dislocation in certain areas of the global economy. Efforts by the Chinese government to orchestrate a controlled revaluation of the Chinese yuan have not gone smoothly, and its efforts to dampen stock market volatility have not been particularly successful.

Geopolitical risks have become so substantial that they now constitute an important risk factor for global financial markets. The tragic terrorist actions in Paris underscore that terrorism and the responses to it can create significant economic disruption, in addition to the regrettable loss of life and property damage. ISIS’s actions in Syria and throughout the Middle East as well as recent tension between Iran and Saudi Arabia also are indicative of an especially unsettled time—even for an area that has experienced substantial turmoil over many decades.

We recognize that global growth could be inconsistent, the chance of a recession has increased modestly, and geopolitical tensions have rarely seemed more vexing. However, there are reasons to be constructive and even optimistic. There are unmistakable signs of improvement in several sectors of the U.S. economy, and durable growth companies could also generate strong profitability. A backdrop of slow but sustained growth can be supportive for these types of stocks and the overall market. The market’s recent declines, a subdued interest rate environment, and improving corporate profits could offset various risks and drive positive stock performance.

The U.S. economy continued to grow, with housing, auto, and retail sales supporting a recovery that appears to be slow but sustainable. Job creation has also shown notable improvement, with 221,000 nonfarm payroll jobs being created on average every month for the past year. Unfortunately, the labor force participation rate is near an all-time low, and the growth in average hourly earnings has been tepid although the trend is improving. There has been stronger wage growth in certain industries, and there are enough signs of economic improvement that the Federal Reserve increased short-term interest rates in December. Recent weakness in manufacturing data and the continued deflationary effect of low oil and other commodity prices probably means that additional rate increases will be limited in 2016.

The U.S. economy is on sounder footing than the economies of many other developed countries, including most European nations. Although European economies appeared to be showing broad improvement, the latest flare-up in the debt markets as well as repercussions from the Paris terrorist attacks could dampen progress. China’s growth could continue to slow or remain inconsistent given stock market and foreign exchange volatility. Brazil, Russia, and several other resource-exporting emerging markets economies are struggling with inconsistent growth and must be carefully monitored as their size and influence on the global economy is noteworthy.

Unfortunately, geopolitical risks are probably as great as we have seen in the last few decades. Egypt; Syria; Turkey; and also countries in the Western Hemisphere, such as Brazil, have experienced a notable amount of internal strife, and there have been a number of terrorist actions in the last several months, including mass murders in several developed countries.

It is also worth noting that 2016 is an election year, and the pursuit of the White House is likely to be quite vigorous. The two major parties have different views on several issues that could have far-reaching effects on several industries, such as health care. If the Republicans are able to win the presidency and control the executive branch and both houses of Congress, it, perhaps, could lead to more significant changes. However, both parties appear to be favoring candidates with forceful agendas that could create greater opportunity, but also risk for various industries.

While recognizing the many challenges facing investors, we believe there are several powerful positives and appreciation potential for many stocks. Solid revenue growth; improved efficiency and margins; and, ultimately, robust corporate earnings are being generated despite subdued capital expenditures. As overall demand improves, corporate earnings could be quite vibrant. Many companies have free cash flow yields approaching 10%, which is very favorable relative to the yield on 10-year Treasury notes. Also, companies are repurchasing their shares consistently, leading to a rare decline in the net overall amount of shares outstanding in the market. However, some stocks have performed well, and we want to be clear that the opportunity for continued gains is necessarily less substantial for selected stocks at current price levels.

Although we had some large detractors in the consumer discretionary, information technology, and industrials and business services sectors, our holdings in these areas performed well and produced a substantial portion of our gains for the year.

In the consumer discretionary area, our large position in Amazon.com was the portfolio’s top performer in the second half and for the year by a large margin. The company is investing heavily in a number of areas, and its profitability has been lackluster. Fortunately, third-party sales and Amazon Web Services (AWS), which provides cloud processing services for other companies, generate above-average profit margins. These businesses have grown rapidly and have propelled a significant recovery in gross margin. The company also provided greater disclosure for AWS, demonstrating that this business is far more profitable than many had previously believed. Our longtime holding in Priceline, a leading online travel services provider, continued to generate solid earnings and free cash flow growth and performed well. Netflix was also a top contributor. The company has grown its domestic and international subscriber base at a rapid pace. Its strategy of providing more original content appears to be driving new subscriber growth while also limiting subscriber turnover. Our recent research revealed that the company has some important skills and advantages in licensing content directly with entertainers and other content providers. Additionally, Netflix just announced an accelerated rollout of products in 130 countries. (Please refer to the portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Home improvement retailing giants Home Depot and Lowe’s produced notable contributions to performance as an ongoing housing recovery and improved merchandising and operational efficiencies drove strong profit growth. Starbucks continued to be a solid performer as its food offerings, fruit juices, and teas appear to be gaining traction. It has also opened Reserve Roastery & Tasting Rooms that offer premium blends and a tasting room experience that seems to resonate with coffee aficionados. Recent visits to its headquarters provide evidence of impressive management depth and product innovation. O’Reilly Automotive is a high-quality auto parts retailer with a reputation for outstanding service. This longtime holding continued to generate strong revenue and earnings growth and returns. It has been actively repurchasing large amounts of stock. The auto parts retailing industry produced solid gains for the portfolio, and AutoZone also generated strong performance.

Nike bucked the trend of slowing growth that some consumer products companies have experienced. Its product innovations and future order patterns in the last several quarters have been impressive. Management has controlled costs well and the resultant earnings gains drove the stock higher. Royal Caribbean Cruises and Norwegian Cruise Line Holdings are benefiting from larger ships, newer fleets, and improved capacity planning. As the cruise line operators expand into new markets, such as China, ships have been redeployed from other areas. This has helped improve overall profit margins, earnings growth, and stock performance. A variety of high-quality retailing companies that we have held for several years also produced solid appreciation. Ross Stores; Costco Wholesale; and L Brands, which operates Victoria’s Secret and Bath & Body Works, have produced consistent comparable-store sales, earnings growth, and share price gains.

In the technology area, Alphabet (formerly Google) was our largest contributor in the past six months and for the year. The company’s search and advertising businesses are thriving, and YouTube is experiencing exceptionally strong growth in viewing time and sharply improving profitability as increased advertising is being used to monetize that business. The company has hired a new chief financial officer who appears to be taking a disciplined approach in expense management and capital allocation. Alphabet’s holding company structure has improved its financial disclosure and transparency. The company’s core operations are reported separately from its new ventures, which are generally producing losses that now can be isolated by investors. Facebook, another top contributor for the past six and 12 months, rallied as investors began to appreciate how well the company’s advertising products, video strategy, and Instagram photo sharing are being received. Its investment in WhatsApp and Messenger provide solid positioning in the messaging market, which is growing in popularity. Facebook just launched the Oculus virtual reality product at $599, which is a more favorable price point for profitability than the preliminary estimates.

Our growing confidence in the new management team and improved product positioning at Microsoft prompted us to aggressively add to our holding—our largest portfolio addition in the first and second half of the year—the stock rallied at year-end, and we were rewarded with solid gains. Satya Nadella has shown good strategic vision and decisiveness in his new role as chief executive officer, and the company seems to have recast its product offerings to be better positioned for growth in cloud computing. Salesforce.com is a leading cloud-based software and services provider with operations that support sales, services, marketing, and analytics activities for clients. The company has been a holding for several years and continued to perform well. ServiceNow, a leading provider of cloud-based platform-as-a-service offerings to business enterprises, continued to expand its presence outside the traditional technology services area. The company is generating solid improvement in profitability and free cash flow and has outperformed many other cloud-based software and services companies. Our patience with LinkedIn has begun to pay off, as the company recovered from a modest stumble earlier in the year in the talent solutions business. The company is the leader in online job search and talent development offerings. Our longtime holdings in credit card processing giants MasterCard and Visa also generated substantial gains. Fiserv, a leading processing solutions provider to businesses and banks, has generated consistent earnings growth for decades, and in 2015, it again generated strong stock performance.

Following a subpar first half of the year, industrials and business services was our third-largest sector contributor to second-half performance. Danaher has been a significant holding and generally a standout performer since the fund’s inception more than 22 years ago. The company’s acquisition of Pall, a high-quality filtration solutions provider, and the concurrent decision to split itself into two publicly-traded companies (expected to be done later in 2016), has been well received by the market. With leading positions in several health care, industrial, water treatment, and process control businesses, Danaher should be able to perform relatively well in most economic scenarios. Roper Technologies also generates free cash flow as a percentage of net income that is among the strongest in the industrials and business services sector and produced solid stock gains in the back half of the year. Boeing and American Airlines have been controversial stocks, but in both cases, our analyst’s strong belief that earnings and free cash flow would be quite strong and drive stock performance has generally been correct.

Valeant Pharmaceuticals International was the largest second-half performance detractor. It is perhaps noteworthy that the company was a significant contributor to performance in the first half of 2015 and in earlier periods. The company has grown through acquisitions, and its purchase of Bausch + Lomb has proven to be particularly accretive to earnings. Valeant’s stock was clobbered first by concerns that the company had increased the prices of some acquired drugs by exorbitant amounts, and then by assertions that it had used a specialty pharmaceutical distributor to improperly inflate sales and profits. There is certainly political sensitivity surrounding drug pricing, and it is true that the prices of certain products were increased substantially. The assertions (made by a short-selling firm) about using a distributor to improperly inflate sales and profits have so far appeared to be without merit, and the stock has experienced a modest recovery. The company has discontinued its relationship with the specialty distributor, signed an important distribution agreement with Walgreens, pledged to reduce prices on a large number of products, earmarked cash flow for debt reduction, and reissued earnings guidance that has been reduced only moderately. We are mindful of the significant debt load the company is carrying and the possibility that other problems could emerge. The temptation in very controversial situations like this is to sell—we did trim some stock before we were able to get better information regarding the key risks—and it is often the right course of action. Nonetheless, we believe that the Bausch + Lomb and Salix Pharmaceuticals, which manufacturers gastrointestinal products, businesses alone justify a significant portion of the current stock price. If our assessment of the company’s earnings power is even approximately correct, the upside for the stock could be substantial.

Health care has become a more controversial area due to concerns about drug pricing. Perhaps because the sector has performed so well for the past five years, it is also susceptible to profit taking. Biotech stocks have been particularly volatile, and our positions in Biogen and Gilead Sciences performed inconsistently and posted second-half losses. Biogen was hurt by slowing sales of its key multiple sclerosis drug, Tecfidera, leading us to reduce our position size moderately. However, Biogen is now trading at a valuation that we think is attractive, and it should receive clinical data on several important pipeline products in the next year, including a treatment for Alzheimer’s. In the interim, this well-managed company has been disciplined in controlling expenses, developing new early-stage products internally, and studying various external product and company acquisition candidates. In a similar way, Gilead’s hepatitis C remedies, Harvoni and Sovaldi, have been so successful that the company now trades at less than eight times forward earnings estimates. Gilead has been disciplined in using its cash flow windfall to acquire products or companies that would allow it to continue growing several years out when the hepatitis product sales taper. We understand the market’s impatience and the uncertainty surrounding potential acquisitions, and we are closely monitoring any actions the company takes. However, management has shown extraordinary skill and foresight in the past.

Leading drug distributor McKesson struggled as generic price inflation has slowed and because it lost several large contracts. Some of the lost business was due to mergers or acquisitions or a change in strategic direction by the customer. For example, Rite Aid is being acquired by Walgreens and Omnicare is being acquired by CVS Health. McKesson released disappointing guidance as a result of these factors, but the guidance does not fully reflect the favorable impact of efficiency improvements and possible increased share repurchases. Management also believes that it can attract new customers—Albertson’s supermarkets, for example. We believe that the stock currently trades at an attractive valuation and intend to maintain a significant position in the company. However, we will trim our large position if we uncover more compelling ideas in the controversial health care industry.

Additions to existing holdings, such as Microsoft, Bristol-Myers Squibb, Vertex Pharmaceuticals, Royal Caribbean Cruises, UnitedHealth Group, Eli Lilly, Aetna, and American Airlines were significant enough to be included among our largest purchases for the past six months. The only new position that was large enough to be included in the top 10 purchases was Alaska Air Group, a well-managed airline with growing market share in Seattle and other key western markets. The company has consistently operated very efficiently, which has helped generate return on invested capital, earnings, and free cash flow that are among the best in the airline industry. It has begun to expand more aggressively from its Seattle hub, which has driven revenue and earnings growth, but this has also exposed the company to increased price competition. Some of its business is sourced in Alaska, which has been hurt by the sharp decline in energy and commodity prices. These risks will have to be monitored, but the company’s superior management, cost structure, and growth outlook make this a promising idea, in our view.

There were two eliminations large enough to be included in the top 10 sales for the second half of 2015. We sold Precision Castparts after news that it was being acquired by Warren Buffett’s Berkshire Hathaway at a modest premium. We also eliminated EQT because of our expectations for a protracted period of natural gas oversupply and depressed pricing. In addition to being a quality natural gas producer, EQT possesses valuable midstream (gathering and transmission) assets. We would generally not let short-term price fluctuations dictate our stance on an energy holding. However, we believe that natural gas prices are likely to remain lower for longer (several years) than the market’s consensus estimates.

The market got off to a rocky start in 2016. It seems that certain risks have either intensified or have been supplemented by a new set of challenges. Although this is often the nature of investing, uncertainty and risk have risen regarding disruptive foreign currency fluctuations and slowing economic growth, particularly in China. The energy and commodity complex is under significant stress, and some respected economists also believe the chance of a recession or a more significant slowdown has increased. Terrorism is a factor that could have a more frequent and significant injurious effect on global markets. Given the appreciation of some stocks, we think the valuations of some companies are no longer attractive. However, after the early 2016 pullback, valuation is perhaps not as much of a limiting factor to stock gains.

Although recent employment reports in the U.S. generally have been encouraging, tepid economic growth, a relatively high level of unemployment, and lackluster income growth in many developed countries represent key concerns. Regrettably, growth has slowed in several emerging economies, and the recent slowing in China and, particularly, in Brazil are noteworthy given their size and importance in the global growth equation. While we have seen improvement in budget deficits and growth in Europe and the U.S., structural reform and spending reductions are almost certainly necessary. In addition to these fiscal actions, many central banks will eventually tighten the accommodative monetary policy they are currently pursuing. However, the latest data and developments suggest that the Federal Reserve could be quite restrained in increasing interest rates.

We would also be quick to acknowledge that policymaking to address all of these situations is complex, risky, and unlikely to yield results that are unequivocally favorable. Said another way, all of the solutions have costs and, perhaps, unintended consequences. One unintended and undesirable side effect could be a sharp or persistent rise in inflation. However, we must acknowledge that gold and energy prices would support the view that inflation is not a major problem at this juncture. There are other complicating factors that may weigh on markets for some time. Aside from the rising risk posed by terrorism, longstanding but intensifying unrest in the Middle East could affect general global stability, and we also have taken note of the major protests and unrest that have occurred in Brazil. Cyberattacks represent an evolving challenge for businesses and possibly financial markets, whether they are pursued by governments or terrorists. A possible downgrade of U.S. government debt, instability in the dollar or other major currencies, and a sharp increase in interest rates constitute threats that must be carefully monitored. For these reasons (and several others), we regard the current environment as having more complexity and risk than are typical.

On balance, we remain constructive on the long-term performance of stocks. While the challenges we have outlined will certainly require time to resolve and will test the patience of policymakers and investors, corporate earnings at selected companies could continue to impress, interest rates and inflation should remain at acceptable levels, and the valuations of many high-quality companies are reasonable.

Despite the uncertainty surrounding how effective fiscal and monetary actions will be in addressing various risks, there are several things working in our favor:

1. Stocks historically have performed quite well following a lackluster period of performance. Essentially, we have experienced two very major bear markets since 2000.

2. Recent market strength over the past few years does temper the amount of potential appreciation. However, given the recent correction, the valuations of stocks are attractive—especially in relation to the very low level of interest rates. The spread between the earnings yield on stocks and the 10-year Treasury rate is attractive in any historical context. The free cash flow yield of many companies exceeds 10% and implies very attractive valuations, especially in the context of 10-year Treasury note yields of approximately 2.2%.

3. We believe that the high-quality, consistent-growth companies that we seek to purchase are especially attractive and could conceivably do well even if the economy only experiences modest growth. Stringent expense management could also support rapid earnings growth if revenues begin to accelerate.

4. Many large-cap growth companies have strong balance sheets with record amounts of cash and strong capitalization. This should allow them to opportunistically invest in new products or businesses or make acquisitions as change creates dislocation.

5. Many of our holdings generate significant free cash flow. Shareholder-oriented management can use this cash to pay dividends, repurchase shares, or make value-added acquisitions.

We continue to strive to enhance returns in a difficult environment by investing in quality companies with durable, sustainable earnings and cash flow growth. We appreciate your continued confidence in this endeavor.

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. Growth stocks can be volatile because these companies usually invest a high portion of earnings in their businesses, and earnings disappointments often lead to sharply falling prices. The value approach carries the risk that a security’s intrinsic value may not be recognized for a long time or that the stock may actually be appropriately priced.

Dividend yield: The annual dividend of a stock divided by the stock’s price.

This chart shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

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 four share classes: The original share class (Investor Class) charges no distribution and service (12b-1) fee, Advisor Class shares are offered only through unaffiliated brokers and other financial intermediaries and charge a 0.25% 12b-1 fee, R Class shares are available to retirement plans serviced by intermediaries and charge a 0.50% 12b-1 fee, and I Class shares are 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.

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.

T. Rowe Price Blue Chip Growth 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. Income is a secondary objective. The fund has four classes of shares: the Blue Chip Growth Fund original share class, referred to in this report as the Investor Class, offered since June 30, 1993; the Blue Chip Growth Fund–Advisor Class (Advisor Class), offered since March 31, 2000; the Blue Chip Growth Fund–R Class (R Class), offered since September 30, 2002; and the Blue Chip Growth Fund–I Class (I Class), offered since December 17, 2015. Advisor Class shares are sold only through unaffiliated brokers and other unaffiliated financial intermediaries, and R Class shares are available to retirement plans serviced by intermediaries. I Class shares generally are available only to investors meeting a $1,000,000 minimum investment or certain other criteria. The Advisor Class and R Class each operate under separate Board-approved Rule 12b-1 plans, pursuant to which each class compensates financial intermediaries for distribution, shareholder servicing, and/or certain administrative services; the Investor and I Classes do not pay Rule 12b-1 fees. Each class has exclusive voting rights on matters related solely to that class; separate voting rights on matters that relate to all classes; and, in all other respects, the same rights and obligations as the other classes.

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. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions 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 to shareholders are recorded on the ex-dividend date. Distributions from REITs are initially recorded as dividend income and, to the extent such 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. 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 all 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. The Advisor Class and R Class each pay distribution, shareholder servicing, and/or certain administrative expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25% and 0.50%, respectively, of the class’s average daily net assets.

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 $261,000 for the year ended December 31, 2015.

In-Kind Redemptions In accordance with guidelines described in the fund’s prospectus, the fund may distribute portfolio securities rather than cash as payment for a redemption of fund shares (in-kind redemption). For financial reporting purposes, the fund recognizes a gain on in-kind redemptions to the extent the value of the distributed securities on the date of redemption exceeds the cost of those securities. Gains and losses realized on in-kind redemptions are not recognized for tax purposes and are reclassified from undistributed realized gain (loss) to paid-in capital. During the year ended December 31, 2015, the fund realized $545,923,000 of net gain on $870,468,000 of in-kind redemptions.

New Accounting Guidance In May 2015, FASB issued ASU No. 2015-07, Fair Value Measurement (Topic 820), Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). The ASU removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and amends certain disclosure requirements for such investments. The ASU is effective for interim and annual reporting periods beginning after December 15, 2015. Adoption will have no effect on the fund’s net assets or results of operations.

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.

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)

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 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.

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 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.

Valuation Inputs The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on December 31, 2015:

There were no material transfers between Levels 1 and 2 during the year ended December 31, 2015.

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.

Securities Lending The fund may lend its securities to approved brokers to earn additional income. Its securities lending activities are administered by a lending agent in accordance with a securities lending agreement. Security loans generally do not have stated maturity dates, and the fund may recall a security at any time. The fund receives collateral in the form of cash or U.S. government securities, valued at 102% to 105% of the value of the securities on loan. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities; any additional collateral required due to changes in security values is delivered to the fund the next business day. Cash collateral is invested by the lending agent(s) in accordance with investment guidelines approved by fund management. Additionally, the lending agent indemnifies the fund against losses resulting from borrower default. Although risk is mitigated by the collateral and indemnification, the fund could experience a delay in recovering its securities and a possible loss of income or value if the borrower fails to return the securities, collateral investments decline in value, and the lending agent fails to perform. Securities lending revenue consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower, compensation to the lending agent, and other administrative costs. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying financial statements, but collateral received in the form of securities is not. At December 31, 2015, the value of loaned securities was $3,384,000 including securities sold but not yet settled, which are not reflected in the accompanying Portfolio of Investments; the value of cash collateral and related investments was $3,495,000.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $11,528,262,000 and $9,568,492,000, respectively, for the year ended December 31, 2015.

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 fund files U.S. federal, state, and local tax returns as required. The fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

Reclassifications to paid-in capital relate primarily to the current net operating loss, redemptions in kind, and a tax practice that treats a portion of the proceeds from each redemption of capital shares as a distribution of taxable net investment income or realized capital gain. For the year ended December 31, 2015, the following reclassifications were recorded to reflect tax character (there was no impact on results of operations or net assets):

Distributions during the years ended December 31, 2015 and December 31, 2014, were characterized for tax purposes as follows:

At December 31, 2015, the tax-basis cost of investments and components of net assets were as follows:

The difference between book-basis and tax-basis net unrealized appreciation (depreciation) is attributable to the deferral of losses from wash sales for tax purposes. 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. The fund’s available capital loss carryforwards as of December 31, 2015, $32,424,000 have no expiration.

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 and a group fee. The individual fund fee is equal to 0.30% of the fund’s average daily net assets up to $15 billion and 0.255% of the fund’s average daily net assets in excess of $15 billion. 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 0.275% for assets in excess of $400 billion. The fund’s group fee is determined by applying the group fee rate to the fund’s average daily net assets. At December 31, 2015, the effective annual group fee rate was 0.29%.

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. Pursuant to this agreement less than $1,000 of expenses were waived/paid by Price Associates during the year ended December 31, 2015 and remain subject to repayment by the fund.

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 R Class. For the year ended December 31, 2015, expenses incurred pursuant to these service agreements were $107,000 for Price Associates; $4,490,000 for T. Rowe Price Services, Inc.; and $5,544,000 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.

Additionally, the fund is one of several mutual funds in which certain college savings plans managed by Price Associates may invest. As approved by the fund’s Board of Directors, shareholder servicing costs associated with each college savings plan are borne by the fund in proportion to the average daily value of its shares owned by the college savings plan. For the year ended December 31, 2015, the fund was charged $1,211,000 for shareholder servicing costs related to the college savings plans, of which $892,000 was for services provided by Price. The amount payable at period-end pursuant to this agreement is reflected as Due to Affiliates in the accompanying financial statements. At December 31, 2015, approximately 3% of the outstanding shares of the Investor Class were held by college savings plans.

The fund is also one of several mutual funds sponsored by Price Associates (underlying Price funds) in which the T. Rowe Price Spectrum Funds (Spectrum Funds) may invest. The Spectrum Funds do not invest in the underlying Price funds for the purpose of exercising management or control. Pursuant to a special servicing agreement, expenses associated with the operation of the Spectrum Funds are borne by each underlying Price fund to the extent of estimated savings to it and in proportion to the average daily value of its shares owned by the Spectrum Funds. Expenses allocated under this agreement are reflected as shareholder servicing expense in the accompanying financial statements. For the year ended December 31, 2015, the fund was allocated $615,000 of Spectrum Funds’ expenses, of which $412,000 related to services provided by Price. At period-end, the amount payable to Price pursuant to this agreement is reflected as Due to Affiliates in the accompanying financial statements. At December 31, 2015, approximately 2% of the outstanding shares of the Investor Class were held by the Spectrum Funds.

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.

As of December 31, 2015, T. Rowe Price Group, Inc., or its wholly owned subsidiaries owned 3,453 shares of the I Class, representing less than 1% of the fund’s net assets.

To the Board of Directors and Shareholders of
T. Rowe Price Blue Chip Growth Fund, Inc.

In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of T. Rowe Price Blue Chip Growth Fund, Inc. (the “Fund”) at December 31, 2015, the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2015 by correspondence with the custodian and brokers, and confirmation of the underlying funds by correspondence with the transfer agent, provide a reasonable basis for our opinion.

We are providing this information as required by the Internal Revenue Code. The amounts shown may differ from those elsewhere in this report because of differences between tax and financial reporting requirements.

The fund’s distributions to shareholders included $1,313,367,000 from long-term capital gains, subject to a long-term capital gains tax rate of not greater than 20%.

(a) – (d) Aggregate fees billed for the last two fiscal years for professional services rendered to, or on behalf of, the registrant by the registrant’s principal accountant were as follows:

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions.

(b) The registrant’s principal executive officer and principal financial officer are aware of no change in the registrant’s internal control over financial reporting that occurred during the registrant’s second fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting.

(a)(1) The registrant’s code of ethics pursuant to Item 2 of Form N-CSR is attached.
