Market Overview During the fourth quarter of 2018, (Class A shares without sales charge) marginally outperformed the Russell 2000 Growth Index, -21.13% vs -21.65%. Our focus on well-established, higher-quality growth companies is designed to provide investors with both upside participation and a degree of downside protection. Analysis Relative to the benchmark, Industrials, Information Technology, Financials, and Materials were the best-performing sectors, as a result of positive stock selection. Relative to the benchmark, Heath Care and Communication Services sector detracted from performance. Portfolio Review Top individual stock contributors to the Fund's performance included SendGrid, Inc., Aerojet Rocketdyne Holdings, Inc., and WD-40 Company. SendGrid, Inc. is the leading provider of transactional email services and an emerging player in the email marketing space. Twilio announced plans to acquire SendGrid in an all-stock transaction and Sendgrid reported a strong 3Q18 that was above consensus estimates. Aerojet Rocketdyne Holdings, Inc. is a designer, developer, and manufacturer of propulsion systems for aerospace and defense applications. The company reported a very strong 3Q18 driven by an acceleration in two of their key product lines. WD-40 Company produces lubricants, rust preventatives, cleaners, and moisture replacement. The stock outperformed due to investors searching for a recession-resistant, high quality growth company that benefits from an oil price collapse. Over the quarter, the largest detractors from performance were Ligand Pharmaceuticals, Inc., Inogen, Inc., and Matador Resources Company. Ligand Pharmaceuticals Inc. develops drugs which regulates hormone activated intracellular receptors. The stock sold off with the broader biotech sector despite reporting solid Q3 financial results. Inogen, Inc. is a leader in the portable oxygen concentrator segment of the $3 billion domestic home oxygen therapy market. They reported strong revenue growth but accelerated hiring of new salespeople, which hurt profitability. Matador Resources Company is an independent oil and natural gas exploration and production company. The stock sold off with a sharp drop in oil prices. They reported strong financial results during the period. 2

Past performance does not guarantee future results. Outlook and Positioning Our long-term investment process remains the same. We seek dynamic companies with above-average and sustainable revenue and earnings growth that we believe are positioned to outperform. This includes leading firms in structurally attractive industries with committed management teams that have proven records of performance. Looking forward, we expect the growth rate of the U.S. economy to moderate from a solid 2018 while remaining stronger than many other economies around the world. Tighter monetary policy, waning benefit from fiscal stimulus and trade war fallout are the primary reasons for this slowdown. Moderating economic growth and the anniversary of corporate tax cuts will combine to materially slow the pace of earnings growth. The equity markets have started to reflect this scenario with lower valuations and that process could continue in 2019, along with elevated market volatility. We believe that companies with strong secular growth profiles will outperform those in cyclical industries over the intermediate future. Our opportunity set remains compelling and we expect stock selection to continue to drive our relative performance. Our holdings growth trajectory remains superior to the current corporate profit environment, with EPS growth in the most recent quarter of more than 41.6% in the Discovery Fund. Special Risks Small-sized company stock is typically more volatile than that of larger company stock. It may take a substantial period of time to realize a gain on an investment in a small-sized company, if any gain is realized at all. Investments in securities of growth companies may be volatile. Diversification does not guarantee profit or protect against loss. 4

Source: 2018 Morningstar, Inc., 12/31/18. Morningstar ranking is for Class A shares and ranking may include more than one share class of funds in the category, including other share classes of this Fund. Ranking is based on total return as of 12/31/18, without considering sales charges. Different share classes may have different expenses and performance characteristics. Fund rankings are subject to change monthly. The fund's total-return percentile rank is relative to all funds that are in the Small Growth Funds Category. The highest (or most favorable) percentile rank is 1 and the lowest (or least favorable) percentile rank is 100. The top performing fund in a category will always receive a rank of 1. 3. Holdings and sector allocations are subject to change, do not constitute recommendations by OppenheimerFunds, Inc., and are dollar-weighted based on total net assets. Top Holdings exclude cash and cash equivalents. Attribution analysis is a process used to analyze the absolute return (often called contribution) and the excess return (often called relative return) between a portfolio and its benchmark. The total effect measures both the allocation effect to a sector as well as stock selection within a sector. Holdings are subject to change, and are dollar weighted based on total net assets. Negative weightings may result from the use of leverage. Leverage involves the use of various financial instruments or borrowed capital in an attempt to increase investment return. Leverage risks include potential for higher volatility, greater decline of the fund's net asset value and fluctuations of dividends and distributions paid by the fund. * The Morningstar Rating TM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. was rated against the following number of Small Growth funds over the following time periods: For the 3-,5- and 10- year periods, respectively, the Fund was rated 3, 3 and 4 stars among 583 funds in the last three years, 516 funds in the last five years, and 391 funds in the last ten years. Morningstar Rating is for the Y share class only; other classes may have different performance characteristics. Ratings do not consider sales charges and are subject to change monthly. * The Morningstar Analyst Rating is not a credit or risk rating, but a subjective evaluation performed by the analysts of Morningstar, Inc. (Mstar.) Mstar evaluates funds based on five key pillars (process, performance, people, parent and price). Mstar s analysts use this evaluation to identify funds they believe are more likely to outperform over the long term on a risk-adjusted basis. Analysts consider quantitative and qualitative factors and the weighting of each pillar may vary. The Analyst Rating reflects an overall assessment and is overseen by Morningstar s Analyst Rating Committee. The analyst rating scale is five-tiered, with three positive ratings (Gold, Silver, Bronze), a Neutral Rating and a Negative Rating, with Gold being the highest rating and Negative being the lowest rating. The Mstar analyst Ratings should not be used as the sole basis in evaluating a mutual fund and are based on Mstar s current expectations about future events.
