ANNUAL REPORT

March 31, 2024

MESSAGE TO OUR SHAREHOLDERS

(UNAUDITED)

The U.S. markets advanced significantly over the 12-month period ending March 31, 2024. A resilient economic backdrop coupled with the view that the Federal Reserve's monetary policy may effectively control inflation helped push the major market averages to all-time highs. Concurrently, a big pivot in expectations for the Federal Reserve's monetary policy supported the market advance, as investors began to anticipate an eventual decline in interest rates during our annual reporting period.

In addition to the prospect of a more accommodative monetary policy and lower recession risk for the economy, one of the major themes propelling share prices of select companies during the period was artificial intelligence (AI). Simply put, AI refers to the creation of computer systems and machines that can perform tasks that would normally require human intelligence. AI's transformational impact on life as we know it will likely be at least on par with other key recent technological innovations, such as when personal computers became widely available in the 1980s/1990s and smart phones were introduced in the early 2000s.

The potential for businesses is huge as it should enable new and improved products and services, reduce labor costs, and increase productivity. AI requires specialized hardware and software to write machine learning algorithms and to train machines to use the data effectively for their objective purpose. Some of the earliest beneficiaries are companies supplying the equipment (hardware) required to create, train, and run AI models. Because of the incredible amounts of data and data manipulation involved, high-end servers with specific types of semiconductors are required. One of the companies benefitting most is Nvidia, which designs the fastest versions of the graphic processing unit (GPU) type of semiconductors that best "crunch" the data for AI models.

Manufacturers of the best performing memory chips have also performed well given their role to enable AI systems, and the increased use of generative AI is likely to draw more total IT spending to the cloud, which will benefit the large cloud providers like Microsoft, Amazon, and Google. Those companies have the equipment required in greatest scale, as well as the resources necessary to further invest in the AI build-out to meet growing demand.

As investors, we need to evaluate which companies have the resources and abilities to benefit from AI, and how the increasing ubiquity of AI-enabled systems will impact competitive dynamics within industries in both the long- and short-term. We also try to anticipate other "derivative" ideas that are less obvious, such as the enormous demand for electricity needed to operate the data centers where AI programs run. The potential implications of AI are wide-ranging and exciting, and we will continue to monitor the transformational impact closely.

As for our capital markets outlook, the economy is slowing to a more sustainable level of growth, as consumers have spent much of the excess savings accumulated during the pandemic. Higher capital costs are also helping to moderate demand, which is giving previously impaired supply chains time to mend. If demand continues to moderate and the job market continues to loosen, we believe inflationary pressures will moderate further. The Fed's aggressive tightening cycle appears to be addressing inflation, and an unwelcome scenario of stubbornly high inflation coupled with a consumer-led recession appears to be a remote possibility. Additionally, given the higher interest rate backdrop, the Fed now has firepower to stimulate the economy through rate cuts when needed, which we feel provides an important backstop to investor psychology.

As always, thank you for your continued trust and conviction in the Buffalo Funds.

Sincerely,

Laura Symon Browne

President

PORTFOLIO MANAGEMENT REVIEW (UNAUDITED)

BUFFALO DISCOVERY FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Discovery Fund — Investor Class produced a total return of 19.72%, a result that underperformed its benchmark, the Russell Midcap Growth Index, which advanced 26.28%.

What factors influenced performance?

Most economic sectors made a positive contribution to the fund's absolute performance results for the annual report period except for Consumer Staples and Real Estate, which are small sector weightings for the fund. However, weak stock selection within Consumer Discretionary, Information Technology and Financials compared to the benchmark led to relative underperformance. Growth, momentum, and earnings surprise were among the strongest factors driving performance of the benchmark for the period. Meanwhile, factors such as earnings quality and valuation have greatly underperformed. We remain committed to our valuation and higher-quality discipline, which resulted in benchmark relative underperformance over the last 12 months.

Contributors/Detractors

Securities that contributed the most to performance included CrowdStrike Holdings and Copart. Despite weakness from other firms in their industry, CrowdStrike is experiencing accelerating recurring revenue growth. CrowdStrike is well positioned to benefit from increasing spend on endpoint security and cloud workload protection for years to come.

Copart is a leading provider of auction services for the automotive industry. Values for used vehicles spiked following the COVID pandemic due to supply chain disruption and strong consumer demand, and that negatively impacted the number of "total loss" vehicles being brought to auction by insurance companies. That dynamic is now reversing as auto production rebounds and used vehicle prices normalize. Copart is now projecting healthy volume growth with improving margins. Longer term, we see opportunities for international expansion and believe domestic salvage

auction volumes will continue to rise as advanced vehicle technology and rising repair costs drive up total loss rates for insurers.

Securities that detracted from the fund's results included Calix and Aptiv PLC. Calix is a telecom equipment supplier that sells primarily to broadband service providers in small- to medium-sized markets. The company stands to benefit from the federal infrastructure bill, which aims to extend broadband access into rural markets. However, financial results missed expectations with some key customers delaying purchases as they evaluate these new federal programs and apply for funds. Estimates for 2024 have moved sharply lower, but we believe this is largely a timing issue and that Calix appears well-positioned for a strong recovery once these federal programs are underway.

Aptiv PLC is a supplier to the automotive industry with products that support electrical architectures, safety/perception systems, mobile connectivity, and in-vehicle software. These are some of the fastest growing segments within the auto industry. However, earnings estimates have been pressured by slowing production growth in Europe and Asia, as well as moderating demand for electric vehicles in North America. This is on top of numerous challenges faced over the past year, including supply chain shortages, raw materials inflation, foreign exchange headwinds, and a UAW strike. Investors have clearly grown weary of bad news, but we see substantial value at current levels. Aptiv continues to win market share, and margins should get a boost from pricing actions and cost reduction. The company has capacity to repurchase $3 billion of stock over the next two years, and it is looking to scale back investment in its money-losing autonomous driving joint venture. With earnings growing at an 18-20% pace over the next few years and returns on capital improving, shares look undervalued for this leader in automotive innovation.

Positioning/Outlook

The economy has been surprisingly robust, supported by solid job growth and healthy (but decelerating) wage gains. The upside from job growth has surprised investors and runs contrary to leading economic indicators that had suggested slower growth ahead.

(Unaudited)

Elevated levels of workers, infrastructure spending, investments in AI, and inventory rebuilding appear to be driving upside growth versus prior forecasts. This bodes well for economic expansion, but lowers the odds of rate cuts and makes it more challenging for the Fed to tame inflation. With consumer spending growth now normalizing in the 3% to 4% range, inflation is stickier than desired. It appears consumers are becoming more selective in their purchases, which was a consistent theme from management teams on recent earnings calls.

In this environment, we remain biased to stable-growth franchises and businesses with secular tailwinds that are taking market share. As mentioned above, growth, momentum, and earnings surprise were among the strongest factors driving performance as we write this update. Meanwhile, factors such as earnings quality and valuation have significantly underperformed. We remain committed to our valuation discipline and refrain from chasing crowded, expensive stocks. Given the wide valuation gap between secular growth and quality, we will look to selectively add to quality companies on weakness and trim stocks that have surpassed our price targets. We recognize these valuation disparities can run further and longer than desired, so we will move methodically and patiently with a keen focus on company fundamentals and risk mitigation.

We are still finding high-quality companies benefiting from disruptive innovation and secular tailwinds. Innovative growth businesses with strong balance sheets, scalable business models, and wide competitive moats — whether they manufacture medical devices, cybersecurity software, or innovative consumer products — are likely to outperform in a slower growth environment. This long-term, risk-aware view has served us well in the past and we believe it will lead to a continued compounding of attractive returns over time.

BUFFALO DIVIDEND FOCUS FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Dividend Focus Fund — Investor Class produced a total return of 27.31%, a result that underperformed its benchmark, the Russell 1000 Index, which advanced 29.87%.

What factors influenced performance?

All economic sectors made a positive contribution to the fund's absolute performance results for the period.

However, the fund's sector allocation impact led to benchmark underperformance, particularly the fund's underweight to Information Technology which was a strong performing sector for the benchmark during the period. Stock selection within Information Technology also trailed the benchmark results. Partially offsetting results in Information Technology was the fund's stock selection in Communication Services, Energy, Health Care, Materials, and Utilities, which delivered positive performance compared to the index.

Contributors/Detractors

Securities that contributed the most to performance included Meta Platforms, Microsoft Corporation, and Vistra Corporation. Meta Platforms rose on strong earnings, the initiation of a dividend, and the announcement of a $50 billion stock buyback program. Shares of Microsoft advanced on healthy earnings, as the company appears poised to benefit from the enthusiasm around AI (artificial intelligence). Vistra, a utility and power generation company, advanced as the company has become an AI beneficiary, as growth in data centers should increase demand for electricity.

Securities that detracted from the fund's results included Enviva Inc., Community Healthcare Trust Inc., and PTC Therapeutics. Enviva, which operates in the production, processing, and distribution of wood biomass to power generators, declined on disappointing earnings and the elimination of their dividend. Community Healthcare Trust, a healthcare real estate property and leasing company, declined as a result of a tenant bankruptcy filing and rising interest rates, which negatively impacted the company's cost of capital. PTC Therapeutics, a biopharmaceutical products company that focuses on rare disorders, declined on disappointing trial results and a negative opinion from the European Union on a drug marketing authorization.

Positioning/Outlook

Despite the uncertainty created by the Federal Reserve, domestic politics, and geopolitical tensions, we remain focused on wide moat, large capitalization companies trading at reasonable valuations, in our view. As always, the fund will continue to emphasize competitively-advantaged companies that can be purchased at a fair value. As stock market volatility spikes, we will look for opportunities to find companies that fit our investment criteria, and to be ready when market declines provide better entry points.

BUFFALO EARLY STAGE GROWTH FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Early Stage Growth Fund — Investor Class produced a total return of 7.38%, a result that underperformed its benchmark, the Russell 2000 Growth Index, which advanced 20.35%.

What factors influenced performance?

Stock selection within the Health Care and Information Technology sectors were primarily responsible for relative underperformance during the period. The index, made up of over 1,050 constituents, had a unique development in the fiscal year in that two holdings became some of the largest weightings in the history of the benchmark, and also produced outsized returns. Super Micro Computer and MicroStrategy are seen as beneficiaries of artificial intelligence (AI) investments and a play on bitcoin, respectively. The fund did not hold either company. Super Micro Computer, which advanced nearly 850% for the year, has a $60 billion market capitalization and falls outside the spirit of running a small cap portfolio. MicroStrategy, which advanced over 480%, is a speculative play on the price of bitcoin and does not have a fundamental story behind it.

We believe it is unlikely that we will experience anything like this past year's occurrence especially as Russell moves to reconstitute their indices twice per year to eliminate the potential for what just transpired.

Contributors/Detractors

Kinsale Capital was the top contributor over the past year. The fund has held Kinsale since its initial public offering (IPO) in 2016. The company is a property and casualty insurance company that focuses solely on excess and surplus insurance (E&S) where they write coverages for hard-to-place, small business and personal lines risks. Kinsale has grown at a 40%+ compound annual growth rate (CAGR) over a multi-year time period but still only has a 1.5% market share of the E&S industry. Senior management, which founded Kinsale in 2009, has an average experience of over 30 years in this marketplace and has shown a consistent ability to create value for shareholders. Superior underwriting and an in-house technology stack in a specialized marketplace positions Kinsale favorably to generate attractive growth and capture market share.

The largest detractor from performance was Calix, a provider of hardware and software to rural broadband providers. While a record amount of federal subsidies and incentives are available for rural broadband providers to upgrade and expand their networks, the industry is on pause for the moment as the various federal programs are being vetted and evaluated. This has caused a lull in spending for Calix equipment and software. We believe industry activity will expand in time and Calix is best positioned to capture this opportunity set. Additionally, Calix is early in its efforts to turn these hardware relationships into longer term revenue streams through associated software offerings to help these rural broadband providers better manage their businesses and subscriber bases.

Positioning/Outlook

The employment environment remains strong while consumer sentiment is being pressured by stubborn inflation. The outlook for the Fed to cut rates has dampened materially since late 2023 as economic readings continue to run hotter than expected. Consensus is now forming around two or fewer rate cuts in calendar 2024 versus as many as six rate cuts just five months ago. While inflation is showing progress against the Fed's target of 2%, this does not take away from inflation seen across food, shelter and used vehicles amongst other categories where prices are 25+% higher than pre-Covid levels.

The previous 13 rate cut cycles dating back to 1957 have been very favorable to small cap stocks, with the median return in the first six months approximating 11%. With lowered borrowing costs and lowered discount rates applied to future cash flows, small cap stocks should see immediate benefits from rate cuts. Regardless of the Fed actions, valuation levels of small caps relative to large caps remain at historically attractive levels. Additionally, the performance gap between small cap stocks and large cap stocks remains wide relative to historical levels, and we believe this performance gap will compress over time.

Our job remains to find and hold attractive small cap companies that have not been fully appreciated by the market or are mispriced due to recent results or events. We believe less investor interest in our segment of the market creates an opportunity for us to uncover value over the long term. The fund typically invests at the smaller end of the small cap growth spectrum and the managers continue to seek companies with sustainable growth due to secular growth trends or innovative, disruptive products.

BUFFALO FLEXIBLE INCOME FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Flexible Income Fund — Investor Class produced a total return of 19.37%, a result that underperformed its benchmark, the Russell 3000 Index, which advanced 29.29%.

What factors influenced performance?

All but one economic sector made a positive contribution to the fund's absolute performance results for the period, with the exception being Consumer Discretionary. However, the fund's sector allocation impact was a primary factor leading to underperformance relative to the benchmark. The fund's overweight to the Consumer Staples and Energy sectors impacted relative performance, as those sectors trailed the overall index return for the year. Additionally, the fund's underweight to Information Technology, which was a strong performing sector for the benchmark during the period, also negatively impacted relative performance.

Contributors/Detractors

Securities that contributed the most to performance included Eli Lilly and Microsoft. Eli Lilly's financial results were particularly strong during the period, driven by weight loss drugs. The company also provided 2024 top line and margin guidance that was above expectations and reported a positive Phase II clinical trial result for one of their drugs. Microsoft reported better than expected revenues throughout the period, and earnings consistently beat expectations. Revenue growth was strong across all of its segments and margins also improved.

Securities that detracted from the fund's results included Pfizer and General Mills. Pfizer's decline for the annual reporting period reflected weaker than expected earnings driven by a drop off in COVID vaccine revenues, a slowing base business, and the upcoming loss of exclusivity for certain key products (Eliquis and Ibrance). General Mills suffered from negative earnings revisions and a lower organic revenue forecast.

Positioning/Outlook

the fund will continue to emphasize competitively-advantaged companies that can be purchased at a fair value. As stock market volatility spikes, we will look for opportunities to find companies that fit our investment criteria, and to be ready when market declines provide better entry points.

BUFFALO GROWTH FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Growth Fund — Investor Class produced a total return of 36.01%, a result that underperformed its benchmark, the Russell 3000 Growth Index, which advanced 37.95%.

What factors influenced performance?

All economic sectors made a positive contribution to the fund's strong absolute performance results for the period, however weak stock selection within Health Care and Information Technology led to benchmark underperformance. NVIDIA was a strong contributor to fund performance given the stock advanced over 225% in the period; however, the fund's average weight of about 3.25% vs. the benchmark's average weight of nearly 5% contributed to performance shortfall for the fund.

Contributors/Detractors

Securities that contributed the most to performance included Microsoft and NVIDIA. Microsoft gained over 47% in the period and is the fund's largest position. The company has been investing heavily in the development of AI-powered solutions across its various business segments, such as using AI to enhance productivity and efficiency in its Azure cloud infrastructure, Search, and Office software suite. Microsoft will likely continue to grow their leading share in cloud computing, gaming, and MS Office productivity applications.

As mentioned above, shares of NVIDIA advanced over 225% during the annual reporting period. The company consistently reported sales and earnings ahead of Wall Street's expectations throughout the year with greater than expected growth driven by its products that are in great demand for AI applications. The company has obtained a wide moat around the AI ecosystem and is well-positioned to capture the lion's share of AI infrastructure buildouts.

Securities that detracted from the fund's results included Bio-Rad Laboratories and Calix. Bio-Rad Laboratories is a

(Unaudited)

supplier of products and services to the life sciences industry, including reagents, consumables, diagnostic testing systems, and software. The company cut its earnings forecast following the release of first-quarter earnings. Life sciences and biopharma industries have not been immune from macroeconomic uncertainty and supply chain disruption, and some of the inventory stockpiling that took place during the pandemic is now being reduced. We believe the slowdown is temporary, though, and valuation is now compelling. Giving Bio-Rad Laboratories credit for its net cash position and stake in German bioprocess leader Sartorius, the company trades at roughly half the valuation of industry leaders Danaher and Thermo Fisher.

Calix is a telecom equipment supplier that sells primarily to broadband service providers in small- to medium-sized markets. The company stands to benefit from the federal infrastructure bill, which aims to extend broadband access into rural markets. However, financial results missed expectations with some key customers delaying purchases as they evaluate these new federal programs and apply for funds. Estimates for 2024 have moved sharply lower, but we believe this is largely a timing issue and that Calix appears well-positioned for a strong recovery once these federal programs are underway.

Positioning/Outlook

The outlook for growth stocks is encouraging. The economy is slowing to a more sustainable level of growth, as consumers have spent much of the excess savings accumulated during the pandemic. Higher capital costs are also helping to moderate demand, giving supply lines time to mend. With demand moderating and the job market loosening, we believe inflationary pressures will moderate. The Fed's aggressive tightening cycle appears to be addressing inflation, and an unwelcomed scenario of stubbornly-high inflation coupled with a consumer-led recession appears to be off the table. Moreover, the Fed now has firepower to stimulate when needed, which provides an important backstop to investor psychology. In our opinion, the market environment favors growing, high quality, self-funded companies with durable moats.

Our process is to invest in high quality, well-funded businesses that benefit from secular trends. Regardless of what happens with the economy or broader equity markets, we will strive to maximize risk-adjusted returns in the portfolio by investing in attractively-valued businesses with solid growth opportunities, durable competitive advantages, scalable business models, and exceptional management teams.

BUFFALO HIGH YIELD FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo High Yield Fund — Investor Class produced a total return of 12.07%, a result that outperformed its benchmark, the ICE BofA US High Yield Index, which advanced 11.12%.

What factors influenced performance?

The U.S. high yield bond sector generated posted positive returns in all four quarters of our annual reporting period, as the Fed paused hiking the Federal Funds rate in July, economic data continued to signal resiliency, and the market began anticipating rate cuts for 2024. According to JP Morgan, the return on CCC-rated bonds significantly outperformed the single-B rated and doubled the BB-rated issues during the fiscal year (CCC = 18.86%, B = 11.94%, BB = 9.16%) as investors searched for wider spreads in anticipation of more aggressive Fed rate cuts.

Contributors/Detractors

The top three contributors were Uniti Group LP 10.500% corporate bonds, Vista Outdoor 4.500% corporate bonds, and Energy Transfer LP 7.125% corporate bonds. The 10.500% coupon and annuity-like cash flows attracted investors to the Uniti Group's bonds during the year. Vista Outdoor benefited from the announcement that the company would be acquired by The Czechoslovak Group and the bonds will be repaid at par once the acquisition is finalized. Energy Transfer LP rallied as investors were drawn to its bonds due to their near-investment grade quality and longer-duration characteristics which should benefit the bonds in a declining interest rate environment.

Southwest Airlines 1.250% convertible bonds, Tutor Perini term loans, and the iHeart Communications 8.375% corporate bonds were the worst performers during the fiscal year. Southwest Airlines' convertible bonds were negatively impacted by disappointing earnings results reported in July as well as several safety issues at Boeing that have delayed the delivery of new planes, affecting the entire commercial airline industry. Tutor Perini's loans underperformed as the company reported multiple quarters of disappointing earnings and diminishing backlog. The iHeart Communication's bonds suffered

(Unaudited)

from multiple headwinds negatively affecting the radio/advertising industry throughout the year.

Positioning/Outlook

We are principally focused on the Federal Reserve's balancing act between taming inflation while avoiding a recession, lingering supply chain disruptions, and geopolitical uncertainty. The fund is being managed cautiously yet actively, focusing on high-quality issuers with defensive business models and manageable credit metrics. The portfolio managers will continue to deploy cash in opportunities that we believe offer the most appealing risk/reward tradeoff with a bias toward shorter durations and less levered credits. Additionally, we believe bank loans offer a more defensive position as they provide senior positioning in the capital structure and less interest rate sensitivity due to their floating rate structures. Finally, we continue to look for opportunities in convertible bonds and preferred stocks. We ended the year with 142 securities in the portfolio, up from the previous year's level of 137, excluding cash.

BUFFALO INTERNATIONAL FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo International Fund — Investor Class produced a total return of 10.89%, a result that underperformed its benchmark, the FTSE All-World exUS Index, which advanced 13.99%.

What factors influenced performance?

All economic sectors except for Consumer Staples made a positive contribution to the fund's performance results for the period. However, the fund's sector allocation impact and weak stock selection with Consumer Staples, specifically, led to underperformance compared to the benchmark. In terms of sector impact, the fund's underweight to Financials, a strong performing sector for the benchmark during the period, detracted from relative performance. Stock selection within Consumer Staples also trailed the benchmark, particularly beverage companies and luxury apparel and accessory brands which declined. Partially offsetting these results were the fund's investments to select Materials companies, which delivered positive performance compared to the index.

Contributors/Detractors

Securities that contributed significantly to performance included Disco Corporation and Taiwan Semiconductor

Manufacturing Company (TSMC). Shares of TSMC, the leading global contract semiconductor manufacturer, rose nearly 50% in the period. TSMC is seeing increased demand for its leading-edge foundry services due to growth in AI-related data center computation, and stabilization in smartphone and personal computer shipments. Management forecasts AI-related data center needs will approach a 50% compound annual growth rate (CAGR) over the next five years. Disco, a manufacturer of machinery for cutting and grinding silicon, rose nearly 220% in the annual period driven by demand for its AI packaging equipment. TSMC is their top customer, accounting for around 9% of Disco's revenue. Following TSMC's commentary on advanced packaging, we expect strong growth for both Disco's equipment and consumables over the next 3-5 years.

BayCurrent Consulting was the largest detractor from the fund's results during the annual period. BayCurrent, a Japanese consulting company, reported below-estimate revenue and earnings due to the loss of a major client and lower consultant utilization resulting from overhiring. Additionally, a shift into IT services alongside their consulting business raised investor concerns about growth, margins, and the new strategy overall. Despite the short-term results, we believe this shift toward a less cyclical, higher-volume business model will ultimately improve free cash flow, and we remain confident in the mid- to long-term story.

Positioning/Outlook

We continue to be cautiously optimistic about the prospects for global equity markets. It has become clearer that anticipated interest rate cuts in the United States will come later than previously hoped. In the European Union, interest rate cuts are becoming more imminent as inflation recedes and the economy remains sluggish. Barring any change in the data, it seems the European Central Bank will most likely cut rates before the U.S. Federal Reserve. The European labor market remains strong, and consumer and business confidence has stabilized, helped by positive real wage growth for the consumer; however, there has not been any pickup in economic growth to date. The continued strength of the U.S. economy, however, has been positive for many European multinational companies that do a portion of their business in America. In Japan, the central bank exiting negative rates could signal a new regime for the country where inflation takes hold and positive economic growth continues.

(Unaudited)

Whatever the future brings, we will continue to look for opportunities in the short term to invest with a long-term view. Our strategy remains the same, seeking quality companies that are benefiting from long-term secular growth trends that also have sound, sustainable business models, competitive advantages, and consistent free cash flow generation with good returns on their investments. We especially like proven management teams that are focused on creating value for shareholders. We will seek out opportunities during periods of market weakness or volatility to buy high quality growth companies at attractive valuations. We believe that by continuing our disciplined strategy we should be able to post attractive risk-adjusted returns over the long term.

BUFFALO LARGE CAP FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Large Cap Fund — Investor Class produced a total return of 39.04%, a result that matched its benchmark, the Russell 1000 Growth Index, which advanced 39.00%.

What factors influenced performance?

All economic sectors made a positive contribution to the fund's strong absolute performance results for the period. The fund's results within Information Technology were particularly impactful, gaining nearly 52%, providing the strongest contribution for the year. Fund results within Industrials added the most value compared to the benchmark, partially offset by weaker stock selection for the fund's investments within Financials.

Contributors/Detractors

Securities that contributed the most to performance included NVIDIA and Microsoft. NVIDIA shares continued their prodigious rise that started in January of 2023 with an "eye-popping" return of over 225% during the annual reporting period, as the company significantly raised its guidance and outlook for data center AI chip (GPU) shipments. The company has capitalized on the AI microprocessor opportunity and has, in the process, created the third most valuable company in the world. Some have suggested Nvidia will eventually possess the largest global market cap of any company — a strong possibility. Microsoft also contributed to the fund's strong performance over the past 12 months. The company remains a unique beneficiary of AI, as both an enabler and adopter of the technology.

Tesla was the largest detractor from fund results during the period. The share price of Tesla declined around 30% due to two primary factors: 1) a reduction in deliveries of its battery electric vehicles (BEV) and 2) ongoing uncertainty of the export by China manufacturers of low-cost electric vehicles into western markets, where Tesla currently has leading BEV market share. The reduction in auto deliveries is not unique to Tesla. The worldwide vehicle market has been hampered either by weak economies or an elevated interest rate environment. Inflation in the U.S. (including the "higher for longer" theme) is making the case for a series of interest rate cuts in 2024 more unlikely. This has heightened declining sentiment for Tesla's shares.

Positioning/Outlook

Market returns have been produced by relatively few stocks (the "Magnificent 7") across the large cap benchmarks. Time will tell if this is a leading indicator of market declines, or alternatively, positions other large cap companies to gain ground throughout 2024.

We see growing concerns around the health of the U.S. consumer. Consumer confidence has fallen below expectations, as higher interest rates and elevated gasoline prices impact pocketbooks. Moreover, student loan repayments commenced October 1st, 2023, adding an additional layer of concern on US households' propensity to spend. Partially offsetting these factors is that employment remains strong across the U.S.

Weight loss drugs (GLP-1's, such as Wegovy and Monjaro) created a profound investment narrative during the annual reporting period that has negatively impacted various medical device, consumer discretionary, and consumer staple stocks. The narrative implies structural changes to food and drink consumption and reduced need for medical procedures in areas such as cardiovascular disease and orthopedics. We see selective opportunities to take the other side of this potentially-exaggerated theme, investing in companies that have been overly penalized by GLP-1's perceived weight-loss impact.

Artificial Intelligence also remains a key driver of investor interest. The key question, in our opinion, is how much of the near-term growth is now priced into key AI beneficiary stocks. We have continued to have overweight exposure, generally to a handful of companies where the risk/reward upside is likely to persist over the next six to nine months. Notwithstanding the favorable long-term secular outlook of this macro

(Unaudited)

trend, we do believe there will likely be a digestion point sometime in late 2024 or 2025 where the aggregate AI investment, on a rate of change basis, will decelerate or possibly be negative on a year-over-year basis. The growth outlook of AI investment over the next 10+ years remains unambiguously positive, however.

BUFFALO MID CAP FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Mid Cap Fund — Investor Class produced a total return of 23.74%, a result that underperformed its benchmark, the Russell Midcap Growth Index, which advanced 26.28%.

What factors influenced performance?

All economic sectors made a positive contribution to the fund's absolute performance results for the period, however weak stock selection within Consumer Discretionary and Financials led to benchmark underperformance. Our investing style has been generally out of favor recently. According to the investment bank Jefferies, momentum has been the top performing factor, and quality has been the worst performing factor. This is not in alignment with our investment style. We do not chase stocks with strong recent performance, hoping that it can continue. We invest in high quality stocks as measured by return on invested capital (ROIC), return on assets (ROA), and return on equity (ROE) etc.

Securities that contributed the most to performance included CrowdStrike Holdings and Gartner. Despite weakness from other firms in their industry, CrowdStrike is experiencing accelerating recurring revenue growth. CrowdStrike is well positioned to benefit from increasing spend on endpoint security and cloud workload protection for years to come. Meanwhile Gartner provides research and advisory services, mainly on technology-related topics, to corporate clients. The stock advanced due to strong financial results, highlighted by stabilizing tech vendor spending and salesforce productivity improvements. While artificial intelligence is the current hot topic, we expect Gartner will continue to

benefit from the increasing ubiquity and complexity of IT in all types of businesses.

Securities that detracted from the fund's results included MarketAxess Holdings and Bio-Rad Laboratories. MarketAxess, which operates a platform for electronically trading fixed income securities, declined during annual reporting period driven by soft industry volumes, stagnant market share, and weaker than expected pricing. We believe that these issues are mainly short-term, or macro-driven, and expect the company to benefit from the continued shift to electronic trading in the bond market.

Bio-Rad Laboratories is a supplier of products and services to the life sciences industry, including reagents, consumables, diagnostic testing systems, and software. The company cut its earnings forecast following the release of first-quarter earnings. Life sciences and biopharma industries have not been immune from macroeconomic uncertainty and supply chain disruption, and some of the inventory stockpiling that took place during the pandemic is now being reduced. We believe the slowdown is temporary, though, and valuation is now compelling. Even after giving Bio-Rad Laboratories credit for its net cash position and stake in German bioprocess leader Sartorius, the company trades at roughly half the valuation of industry leaders Danaher and Thermo Fisher.

Positioning/Outlook

The outlook for the Fed to cut rates has dampened materially since late 2023 as economic readings continue to run hotter than expected. Consensus is now forming around two rate cuts in calendar 2024 versus as many as six rate cuts just five months ago. While inflation currently looks stickier than it did a few months ago, the good news is that the odds of a recession in the near term have declined.

Despite inflation being stickier than expected, businesses with pricing power should hold up better than most. Regardless of what happens with the Federal Reserve, economy, or broader equity markets, we will strive to maximize risk-adjusted returns in the portfolio by investing in attractively-valued businesses with solid growth opportunities, durable competitive advantages, scalable business models, and exceptional management teams.

BUFFALO SMALL CAP FUND

How did the Fund perform last year and what affected its performance?

For the 12-month period ended March 31, 2024, the Buffalo Small Cap Fund — Investor Class produced a total return of 3.88%, a result that underperformed its benchmark, the Russell 2000 Growth Index, which advanced 20.35%.

What factors influenced performance?

Contributors/Detractors

Securities that contributed the most to performance included AZEK and PGT Innovations. AZEK, a manufacturer of wood-alternative decking, railing and exterior products for the residential market continues to perform well as the company is benefiting from the conversion away from wood. Currently, wood represents approximately 78% of the decking market and we believe the conversion away from wood provides a secular growth opportunity for the company. Additionally, AZEK should continue to expand margins as the company improves its recycling capabilities. PGT Innovations is a leading manufacturer of residential impact-resistant windows and doors. The company entered into an agreement to be acquired by Masonite International Corp., leading the shares to move higher on the proposed announced acquisition.

Securities that detracted from the fund's results included Avid Bioservices and Treace Medical Concepts. Avid Bioservices, a clinical and commercial manufacturer of biologics for biotechnology and pharmaceutical companies, reported that customer focus shifted from early-stage biotechnology to late-stage projects, which puts pressure on near-term revenues as later-phase work converts to revenue at a slower rate than early stage. Although the near-term might experience volatility, we believe the company's fundamentals are strong and remain confident in Avid's position within their industry as total backlog hit an all-time high and there is good visibility into bookings for next year.

Treace designs, manufactures, and markets orthopedic medical devices for the foot and ankle. Treace's share price action reflected current investor sentiment souring on longer duration stories that are currently unprofitable. Additionally, weight loss drugs, being front and center recently, weighed on many healthcare stocks. We do not believe weight loss drugs will reduce the need for foot and ankle procedures, which are largely caused by other factors, and we remain favorable on Treace's longer-term growth potential. Furthermore, the company is driving toward profitability, which should be a few quarters out.

Positioning/Outlook

The employment environment remains strong while consumer sentiment is being pressured by stubborn inflation. The outlook for the Fed to cut rates has dampened materially since late 2023 as economic readings continue to run hotter than expected. Consensus is now forming around two rate cuts in calendar 2024 versus as many as six rate cuts just five months ago. While inflation is showing progress against the Fed's target of 2%, this does not take away from inflation seen across food, shelter and used vehicles amongst other categories where prices are 25%+ higher than pre-Covid levels.

(Unaudited)

We continue to seek high quality companies that meet our criteria including strong management teams, consistent free cash flow generation, scalable business models, and sustainable competitive advantages. We believe that such companies are well-positioned to weather economic headwinds and deliver sustainable returns, and we feel this approach allows the portfolio to perform well over full market cycles while being mindful of risk.

EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, shareholder servicing fees (Investor Class only) and other Fund specific expenses. The examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Funds 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 period and held for the entire period (October 1, 2023 – March 31, 2024).

ACTUAL EXPENSES

The first line of the tables below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during the period. Although the Funds charge no sales load or transaction fees, you will be assessed fees for outgoing wire transfers, returned checks and stop payment orders at prevailing rates charged by U.S. Bancorp Fund Services, LLC, the Funds' transfer agent. If you request that a redemption be made by wire transfer, currently a $15.00 fee is charged by the Funds' transfer agent. To the extent a Fund invests in shares of other investment companies as part of its investment strategy, you will indirectly bear your proportionate share of any fees and expenses charged by

the underlying funds in which the Fund invests in addition to the expenses of the Fund. Actual expenses of the underlying funds are expected to vary among the various underlying funds. These expenses are not included in the examples below. The examples below include management fees, registration fees and other expenses. However, the examples below do not include portfolio trading commissions and related expenses and other extraordinary expenses as determined under U.S. generally accepted accounting principles.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of each table below provides information about hypothetical account values and hypothetical expenses based on the Funds' actual expense ratios and an assumed rate of return of 5% per year before expenses, which are not the Funds' actual returns. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in our Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the second line of the tables is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different Funds. In addition, if these transactional costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS

MARCH 31, 2024

1. SIGNIFICANT ACCOUNTING POLICIES:

The Buffalo Funds (comprised of the Buffalo Discovery Fund, Buffalo Dividend Focus Fund, Buffalo Early Stage Growth Fund, Buffalo Flexible Income Fund, Buffalo Growth Fund, Buffalo High Yield Fund, Buffalo International Fund, Buffalo Large Cap Fund, Buffalo Mid Cap Fund, and Buffalo Small Cap Fund) (the "Funds") are registered under the Investment Company Act of 1940, as amended (the "1940 Act"), each as a diversified open-end management investment company. The shares of the Buffalo Funds are issued in multiple series, with each series, in effect, representing a separate fund. Kornitzer Capital Management, Inc. ("Advisor" or "KCM") is the Funds' investment adviser.

Each of the Funds offers two classes of shares, Investor Class and Institutional Class. Each class of shares represents an equal interest in the Fund, except the difference of class specific expenses, which reflects the difference in the range of services provided to each class. The shareholder servicing fees for the Investor Class represent the class specific expenses. See Note 7 for more information regarding shareholder servicing fees for the Investor Class. Income, expenses (other than class specific), and realized and unrealized gains and losses on investments are allocated daily to each class based on relative net assets.

The investment objective of the Buffalo Discovery Fund, Buffalo Early Stage Growth Fund, Buffalo Growth Fund, Buffalo International Fund, Buffalo Large Cap Fund, Buffalo Mid Cap Fund and Buffalo Small Cap Fund is long-term growth of capital. The investment objective of the Buffalo Flexible Income Fund is high current income, with long-term growth of capital as a secondary objective. The investment objectives of the Buffalo Dividend Focus Fund and Buffalo High Yield Fund are current income, with long-term growth of capital as a secondary objective.

Each Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 946 "Financial Services — Investment Companies."

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements.

A. INVESTMENT VALUATION — In accordance with FASB ASC 820, Fair Value Measurements ("ASC 820"), fair value is defined as the price that a Fund would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability.

Equity securities and debt securities traded on a national securities exchange or national market, except those traded using the National Association of Securities Dealers' Automated Quotation System ("NASDAQ"), are valued at the latest sales price thereof, or if no sale was reported on that date, the mean between the most recent quoted bid and ask price is used. All equity securities that are traded using NASDAQ are valued using the NASDAQ Official Closing Price ("NOCP"), which may not necessarily represent the last sales price. If there has been no sale on such exchange or on NASDAQ on such day, the security is valued at the mean between the most recent quoted bid and ask price.

When market quotations are not readily available, any security or other asset is valued at its fair value as determined in good faith under procedures approved by the Board of Trustees (the "Board"). If events occur that will affect the value of a Fund's portfolio securities before the net asset value ("NAV") has been calculated (a "significant event"), the security will generally be priced using a fair value procedure. The Board has adopted specific procedures for valuing portfolio securities and delegated the responsibility of fair value determinations to KCM, as the Funds' valuation designee in accordance with new Rule 2a-5 of the 1940 Act. Some of the factors that have been or may be considered by KCM as applicable in determining fair value are fundamental analytical data relating to the investment; the nature and duration of any restriction on disposition; trading in similar securities of the same issuer or comparable companies; information from broker-dealers; and an evaluation of the forces that influence the market in which the

118

securities are purchased or sold. As of March 31, 2024, The Buffalo International and Buffalo Small Cap Funds held securities valued at fair value as determined in good faith by KCM, as valuation designee, at such time. In addition, with respect to the valuation of securities principally traded on foreign markets, the Buffalo International Fund uses a fair value pricing service that employs quantitative models to adjust for "stale" prices caused by the movement of other markets and other factors occurring after the close of the foreign markets, but before the close of the New York Stock Exchange ("NYSE"). As of March 31, 2024, the Buffalo International Fund held 66 securities where a foreign fair value factor was applied, with a market value of $633,787,398 or 58.66% of total net assets.

Debt securities, including treasury bills, commercial paper, corporate and convertible bonds, bank loans, etc., with remaining maturities of 60 days or less are normally valued at the mean in accordance with prices supplied by an approved pricing service. If there is no trade on the valuation date, then the security will be priced at the mean between the most recent bid and ask prices.

Restricted securities include securities that have not been registered under the Securities Act of 1933, as amended, and securities that are subject to restrictions on resale. The Funds may invest in restricted securities that are consistent with the Funds' investment objectives and investment strategies. In some cases, the issuer of restricted securities has agreed to register such securities for resale, at the issuer's expense either upon demand by the Funds or in connection with another registered offering of the securities. Investments in restricted securities are valued utilizing the Funds' valuation policies.

ASC 820 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Funds' investments. The inputs are summarized in the three broad levels listed below:

Level 1 — Valuations based on quoted prices for investments in active markets that a Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

Level 3 — Valuations based on significant unobservable inputs (including a Fund's own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the market place. The inputs will be considered by KCM, along with any other relevant factors, in the calculation of an investment's fair value. The Funds use prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Non-U.S. equity securities actively traded in foreign markets may be reflected in Level 2 despite the availability of closing prices, because the Funds evaluate and determine whether those closing prices reflect fair value at the close of the NYSE or require adjustment, as described above and in Note 9.

Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models rely on one or more significant unobservable inputs and/or significant assumptions made by the Adviser. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

119

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table provides the fair value measurement of applicable Fund assets and liabilities by level within the fair value hierarchy as of March 31, 2024. These assets are measured on a recurring basis.

* Bank Loan securities are bucketed in either Level 2 or Level 3. Bank Loan securities transferred from Level 3 to Level 2 due to increased market activity. The basis for recognizing and valuing transfers is as of the beginning of the period in which transfers occur.

B. FEDERAL INCOME TAXES — Each Fund complies with the requirements of Subchapter M of the Internal Revenue Code necessary to qualify as a regulated investment company and makes the requisite distributions of income and capital gains to its shareholders sufficient to relieve it from all or substantially all federal income and excise taxes. Therefore, no federal income tax provision has been provided.

At March 31, 2024, the Funds did not have any tax positions that did not meet the "more likely-than-not" threshold of being sustained by the applicable tax authority. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as other expense in the Statement of Operations. During the year, the Funds did not incur any interest or penalties.

The Funds have analyzed all open tax years, as defined by the statute of limitations, for all major jurisdictions. Open tax years are those that are open for exam by taxing authorities. Open tax years include the tax years ended March 31, 2021 through March 31, 2024. The Funds have no such examinations in progress.

C. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME — Investment transactions are accounted for on the date the securities are purchased or sold (trade date). Dividend income is recorded on the ex-dividend date except that certain dividends for foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund is informed of the dividend in the exercise of reasonable diligence. Withholding taxes on foreign dividends have been provided for in accordance with the Funds' understanding of the applicable country's tax rules and rates. Interest income is recognized on the accrual basis. Net fee income from bank loan investments is included in interest income for the Buffalo High Yield Fund. Realized gains and losses from investment transactions are reported

122

on the identified cost basis. Gains from the repayment of bank loan principal are included in realized gains. All discounts/premiums are accreted/amortized over the lives of the respective securities for financial reporting purposes and are included in interest income.

D. DISTRIBUTIONS TO SHAREHOLDERS — Distributions to shareholders are recorded on the ex-dividend date. Distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles ("GAAP"). These differences are primarily due to differing treatments for premium amortization on debt securities, deferral of late year and wash sale losses, and partnership investment income.

E. USE OF ESTIMATES — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the year. Actual results could differ from such estimates.

F. FOREIGN CURRENCY TRANSLATION — Values of investments denominated in foreign currencies are converted into U.S. dollars using a spot market rate of exchange on the day of valuation. Purchases and sales of investments and dividend and interest income are translated to U.S. dollars using a spot market rate of exchange prevailing on the respective dates of such transactions. The portion of security gains or losses resulting from changes in foreign exchange rates is included with net realized and unrealized gain or loss from investments, as appropriate, for tax purposes.

G. PURCHASED AND WRITTEN OPTION CONTRACTS — Certain Funds may purchase and write call or put options on securities and indices and enter into related closing transactions. As a holder of a call option, a Fund has the right, but not the obligation, to purchase a security at the exercise price during the exercise period. As the writer of a call option, a Fund has the obligation to sell the security at the exercise price during the exercise period. The Fund's maximum payout in the case of written call option contracts cannot be determined. As a holder of a put option, a Fund has the right, but not the obligation, to sell a security at the exercise price during the exercise period. As the writer of a put option, a Fund has the obligation to buy the underlying security at the exercise price during the exercise period. The Funds did not hold any written put options as of March 31, 2024.

The premium that a Fund pays when purchasing an option or receives when writing an option will reflect, among other things, the market price of the security, the relationship of the exercise price to the market price of the security, the relationship of the exercise price to the volatility of the security, the length of the option period and supply and demand factors. The premium is the market value of an option at the time of purchase.

A purchaser (holder) of a put option pays a non-refundable premium to the seller (writer) of a put option to obtain the right to sell a specified amount of a security at a fixed price (the exercise price) during a specified period (exercise period). Conversely, the seller (writer) of a put option, upon payment by the holder of the premium, has the obligation to buy the security from the holder of the put option at the exercise price during the exercise period.

Exchange traded options are valued at the composite price, using the National Best Bid and Offer quotes ("NBBO"). NBBO consists of the highest bid prices and lowest ask prices across any of the exchanges on which an option is quoted, thus providing a view across the entire U.S. options marketplace. Specifically, composite pricing looks at the last trades on the exchanges where the options are traded. If there are no trades for the option on a given business day, composite option pricing calculates the mean of the highest bid price and lowest ask price across the exchanges where the option is traded. Non exchange traded options also will be valued at the mean between the last bid and ask quotations. For options where market quotations are not readily available, a fair value shall be determined as set forth in the Funds' fair valuation guidelines.

The Funds may use options with the objective to generate income as a non-principal investment strategy. Currently, the Buffalo Flexible Income Fund makes use of the options strategy to a greater extent than the other Funds because high current income generation is a primary investment objective of the Buffalo Flexible Income Fund. The primary strategy used by Buffalo Flexible Income Fund to achieve high current income generation through the use of options is to write covered calls with the strike price above the cost basis and the value the portfolio managers believe will be achieved before the expiration of the option and also at a value that the portfolio managers are willing to sell if the option is exercised. The collected premiums generate income for the Fund, and if the option is exercised, a gain will

123

also be achieved. A risk of using derivatives is that the counterparty to a derivative may fail to comply with their obligation to the Funds. See Note 8 for written option activity.

H. INDEMNIFICATIONS — Under the Funds' organizational documents, officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnification to other parties. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred, and may not occur. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

I. Allocation of Income and Expenses — Each Fund is charged for those expenses directly attributable to it. Expenses directly attributable to a class of shares, such as Shareholder Servicing Fees (See Note 7), are charged to that class of shares. Income, expenses and realized and unrealized gains and losses are allocated to the classes based on their respective net assets.

2. FEDERAL TAX MATTERS:

The tax character of distributions paid during the years ended March 31, 2024 and March 31, 2023 were as follows:

* The Funds designate as long-term capital gain dividends, pursuant to Internal Revenue Code Section 852(b)(3)(C), the amounts necessary to reduce the earnings and profits of the Funds related to net capital gain to zero for the tax period ended March 31, 2024.

For tax purposes, distributions from short-term capital gain distributions are included in ordinary income distributions.

Additionally, GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting.

The differences between book-basis and tax-basis unrealized appreciation/depreciation are attributable primarily to the tax deferral of losses on wash sales, premium amortization, publicly traded partnership investments and passive foreign investment companies.

Other accumulated gain/(loss) is generally comprised of capital loss carryover, qualified late year losses, straddle loss deferrals and/or foreign currency unrealized.

^(a) Represents cost for federal income tax purposes and may differ from the cost for financial reporting purposes.

As of March 31, 2024, the Buffalo Funds had the following capital loss carryovers available to offset future taxable gains:

In order to meet certain excise tax distribution requirements, the Funds are required to measure and distribute annually net capital gains realized during a twelve month period ending October 31 and net investment income earned during a twelve month period ending December 31. In connection with this, the Funds are permitted for tax purposes to defer into their next fiscal year qualified late year capital or ordinary losses. Qualified late year capital losses are any net capital losses incurred between November 1, 2023 and the end of their fiscal year, March 31, 2024. Qualified late year ordinary losses are generally losses incurred between January 1, 2024 and the end of their fiscal year, March 31, 2024.

At March 31, 2024, the following Funds deferred, on a tax basis, qualified late year losses, consisting of ordinary and capital losses, as follows:

3. RELATED PARTY TRANSACTIONS:

Management fees are paid to KCM at the rate of 0.85% per annum of the average daily NAVs of the Funds, except for the Buffalo Early Stage Growth Fund, Buffalo Dividend Focus Fund, Buffalo Growth Fund and Buffalo Large Cap Fund that have a management fee rate of 1.30%, 0.75%, 0.75% and 0.75%, respectively. The management fees are for services that include the costs of all management, supervisory and administrative services required in the normal operation of the Funds. This includes investment management and supervision; fees of the custodian (except for the additional cost of maintaining custody of assets in foreign jurisdictions, when compared to domestic custody costs), independent registered public accounting firm and legal counsel fees; fees and expenses of officers, trustees and other personnel; rent; and other items incidental to corporate administration. Pursuant to a Master Services Agreement with U.S. Bancorp Fund Services, LLC, doing business as U.S. Bank Global Fund Services ("GFS"), KCM pays GFS a fee of 30/100 of 1% (0.30%) of each Funds' average daily net assets out of the fees KCM receives from the Funds, except for the Buffalo Dividend Focus Fund, Buffalo Growth Fund and the Buffalo Large Cap Fund, where GFS receives 25/100 of 1% (0.25%) of such Fund's average daily net assets. GFS provides or obtains various operational services required by the Funds, pays various Fund expenses and acts as paying agent to compensate other Fund service providers. Some of the other Fund service providers are affiliates of GFS. Certain officers of the Funds are also officers and/or directors of KCM.

126

With respect to the Buffalo Small Cap Fund only, the annual management fee rate of 0.85% of the Buffalo Small Cap Fund's average daily net assets is a base fee paid to KCM that is subject to reduced fees paid on assets in excess of certain levels (breakpoints). The fee paid by KCM to GFS is also subject to breakpoints on assets in excess of certain levels. The breakpoint schedules for the management fees paid by the Buffalo Small Cap Fund to KCM and the fees paid by KCM to GFS are set forth in the following table:

BUFFALO SMALL CAP FUND FEE BREAKPOINTS

	(As a % Of Average Daily Net Assets)
Asset Level	Management Fee			GFS Fee
Assets up to $6 billion		0.85	%		0.300	%
Assets over $6 billion up to $7 billion		0.80	%		0.275	%
Assets over $7 billion up to $8 billion		0.75	%		0.250	%
Assets over $8 billion up to $9 billion		0.70	%		0.225	%
Assets over $9 billion		0.65	%		0.200	%

The management fees do not include the cost of acquiring and disposing of portfolio securities, taxes, if any, imposed directly on the Funds and their shares, insurance, certain trustee expenses and the cost of qualifying the Funds' shares for sale in any jurisdiction. With respect to each Fund's Investor Class, the management fees do not include the shareholder servicing fees.

The Buffalo International Fund incurred $151,926 in custody fees during the year ended March 31, 2024, and owed $24,544 for custody fees as of March 31, 2024.

4. AGGREGATE COMPENSATION TO TRUSTEES:

The Funds do not directly compensate any of their trustees. GFS pays trustee fees to non-interested Board members from its share of the management fee that it receives from KCM. The aggregate compensation paid to the Funds' non-interested trustees for their service on the Funds' Board for the year ended March 31, 2024 was $276,000. Interested trustees who are affiliated with KCM do not receive any compensation from the Funds, but are compensated directly by KCM in connection with their employment with KCM.

9. FOREIGN INVESTMENT RISK:

When the Buffalo International Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars. In purchasing or selling local currency to execute transactions on foreign exchanges, the Buffalo International Fund will be exposed to the risk that the value of the foreign currency will increase or decrease, which may impact the value of the portfolio holdings. China has, and may continue to adopt, internal economic policies that affect its currency valuations in a manner that may be disadvantageous for U.S. investors or U.S. companies seeking to do business in China. In addition, a country may impose formal or informal currency exchange controls (or "capital controls"). These types of controls may restrict or prohibit the Buffalo International Fund's ability to repatriate both investment capital and income, which could undermine the value of the portfolio holdings and potentially place the Buffalo International Fund's assets at risk of total loss.

Investing in securities of foreign corporations and governments involves additional risks relating to: political, social, religious and economic developments and conflicts abroad; market instability; fluctuations in foreign exchange rates; different regulatory requirements, market practices, accounting standards and practices; and less publicly available information about foreign issuers. Additionally, these investments may be less liquid, carry higher brokerage commissions and other fees, and procedures and regulations governing transactions and custody in foreign markets also may involve delays in payment, delivery or recovery of money or investments. Investments in common stocks of U.S. companies with international operations, and the purchase of sponsored or unsponsored ADRs (American Depositary Receipt) carry similar risks. In addition to risks associated with investing in foreign securities, there are special risks associated with investments in China and Hong Kong, including exposure to currency fluctuations, less liquidity, expropriation, confiscatory taxation, nationalization, exchange control regulations, differing legal standards and rapid fluctuations in inflation and interest rates. The Chinese government could, at any time, alter or discontinue economic reform programs implemented since 1978.

10. LINE OF CREDIT:

U.S. Bank, N.A. has made available to the Funds an unsecured line of credit pursuant to a Loan Agreement for the Funds which matures, unless renewed, on July 23, 2024. The line of credit is intended to provide short-term financing, if necessary, subject to certain restrictions, in connection with shareholder redemptions. The Funds may borrow up to the lesser of $50,000,000 or certain percentage amounts based on the net assets of the Funds.

The interest rate paid by the Funds on outstanding borrowings is equal to the Prime Rate. As of March 31, 2024, the Prime Rate was 8.50%. None of the Buffalo Funds had borrowings under the credit facility during the year ended March 31, 2024.

11. BENEFICIAL OWNERSHIP:

The beneficial ownership, either directly or indirectly, of more than 25% of a Fund's voting securities creates a presumption of control. As of March 31, 2024, each Fund, except the Buffalo Small Cap Fund, had individual shareholder accounts and/or omnibus shareholder accounts (comprised of a group of individual shareholders), which

129

amounted to more than 25% of the total shares outstanding of the respective Fund. Shareholders with a controlling interest could affect the outcome of proxy voting or direction of management of a Fund.

12. SUBSEQUENT EVENTS:

Management has evaluated the events and transactions that have occurred after March 31, 2024 and through the date the financial statements were issued and determined that there were no significant subsequent events that would require adjustment of the financial statements or additional disclosures.

On May 23, 2024, the Board approved changes to: (i) the name of Buffalo Discovery Fund to "Buffalo Mid Cap Discovery Fund," Buffalo Dividend Focus Fund to "Buffalo Growth & Income Fund," Buffalo Flexible Income Fund to "Buffalo Flexible Allocation Fund," Buffalo Large Cap Fund to "Buffalo Blue Chip Growth Fund," Buffalo Mid Cap Fund to "Buffalo Mid Cap Growth Fund" and Buffalo Small Cap Fund to "Buffalo Small Cap Growth Fund;" (ii) the principal investment strategies of the Funds listed in (i) and the Buffalo Early Stage Growth Fund, Buffalo Growth Fund and Buffalo High Yield Fund; and (iii) the 80% investment policies of the Funds listed in (ii). The proposed effective date for the aforementioned approvals is July 29, 2024.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Buffalo Funds

Opinion on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the schedules of investments and options written, of Buffalo Discovery Fund, Buffalo Dividend Focus Fund, Buffalo Early Stage Growth Fund, Buffalo Flexible Income Fund, Buffalo Growth Fund, Buffalo High Yield Fund, Buffalo International Fund, Buffalo Large Cap Fund, Buffalo Mid Cap Fund, and Buffalo Small Cap Fund (the "Funds"), each a series of Buffalo Funds, as of March 31, 2024, the related statements of operations and changes in net assets, the financial highlights for the year then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of March 31, 2024, the results of their operations, the changes in net assets, and the financial highlights for the period then ended, in conformity with accounting principles generally accepted in the United States of America.

The Funds' financial statements and financial highlights for the years ended March 31, 2023, and prior, were audited by other auditors whose report dated May 25, 2023, expressed an unqualified opinion on those financial statements and financial highlights.

Basis for Opinion

These financial statements are the responsibility of the Funds' management. Our responsibility is to express an opinion on the Funds' financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent

with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2024, by correspondence with the custodian, brokers, and agent banks; when replies were not received from brokers and agent banks, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Funds' auditor since 2024.

APPROVAL OF ADVISORY AGREEMENTS (NOVEMBER 2023)

The Board of Trustees (the "Trustees") of Buffalo Funds, a Delaware statutory trust, on behalf of its series, Buffalo Flexible Income Fund, Buffalo High Yield Fund, Buffalo Large Cap Fund, Buffalo Small Cap Fund, Buffalo Growth Fund, Buffalo Discovery Fund, Buffalo Mid Cap Fund, Buffalo Early Stage Growth Fund, Buffalo International Fund and Buffalo Dividend Focus Fund (all such funds referred to collectively as the "Funds") met in-person on November 16, 2023 to consider the renewal of the Amended and Restated Management Agreements (the "Management Agreements") between the Trust, on behalf of the Funds, and Kornitzer Capital Management, Inc., the Funds' investment adviser (the "Adviser," or "KCM").

In advance of the meeting, the Trustees requested ("15(c) Request for Information") and received materials to assist them in considering the renewal of the Management Agreements. The materials provided contained information with respect to the factors enumerated below, including a copy of the Management Agreements, a memorandum prepared by the Trust's outside legal counsel discussing the Trustees' fiduciary obligations and the factors they should assess in considering the renewal of the Management Agreements, detailed comparative information relating to each Fund's performance, as well as the management fees and expenses of the Funds, the Adviser's Form ADV, select financial information of the Adviser, including a profitability analysis prepared by the Adviser, and other comparative performance and fee information. The Trustees noted they receive information periodically throughout the year that was relevant to the consideration of the Management Agreements.

In addition, the Independent Trustees (as defined below) met with their outside legal counsel on November 7, 2023 and immediately prior to the Board meeting held on November 16, 2023, to review and discuss the 15(c) Request for Information and the Trustees' duties under the Investment Company Act of 1940, as amended, and state law in considering the proposed renewal of the Management Agreements.

Based on their evaluation of information provided by KCM, in conjunction with the Funds' other service providers, the Trustees, by a unanimous vote (including a separate vote of the Trustees who are not "interested persons," as that term is defined in the Investment Company Act of 1940, as amended (the "Independent

Trustees")), approved the renewal of the Management Agreements for an additional term of one year ending November 30, 2024.

In considering the renewal of the Management Agreements, the Trustees reviewed and analyzed various factors that they determined were relevant, including the factors enumerated below.

1. Nature, Extent and Quality of Services Provided to the Funds

The Trustees considered the nature, extent and quality of services provided by KCM to the Funds and the amount of time devoted to the Funds' affairs by KCM's staff. The Trustees considered KCM's specific responsibilities in all aspects of day-to-day management of the Funds, including the investment strategies implemented by KCM, as well as the qualifications, experience and responsibilities of the Funds' portfolio managers and other key personnel at KCM involved in the day-to-day activities of the Funds. In executive session the Independent Trustees reviewed information provided by KCM in response to the Board's 15(c) Request for Information, including the structure of KCM's compliance program, KCM's continuing commitment to the growth of the Funds' assets, KCM's sales and marketing strategies, KCM's continued investment in systems, equipment and other resources. The Trustees noted during the course of the prior year they had met with representatives of KCM to discuss the Funds' performance and outlook, along with the marketing and sales and compliance efforts made by KCM throughout the year. The Trustees also noted any services that extended beyond portfolio management, and they considered the trading capability of KCM, and the lack of both significant shareholder complaints and financial statement issues. The Trustees discussed KCM's handling of compliance matters, including the quarterly and annual reports of the Trust's Chief Compliance Officer to the Trustees on the effectiveness of KCM's compliance program.

The Trustees concluded that KCM had sufficient quality and depth of personnel, resources, investment methods and compliance policies and procedures essential to performing its duties under the Management Agreements and that the nature, overall quality and extent of the management services provided to the Funds, as well as KCM's compliance program, were satisfactory.

After considering all of the information including specific responses regarding Fund performance, including KCM's efforts to improve performance of underperforming Funds, the Trustees concluded that the performance obtained by KCM for the Funds was satisfactory under current market conditions and in light of each Fund's investment objective, strategies and policies. Although past performance is not a guarantee or indication of future results, the Trustees determined that the Funds and their shareholders were likely to benefit from KCM's continued management.

3. Costs of Services Provided and Profits Realized by KCM

The Trustees considered the cost of services and the structure of KCM's fees, including a review of the expense analyses and other pertinent material with respect to the Funds. The Trustees reviewed related statistical information, including the comparative expenses, expense components and peer group selections. The

139

(Unaudited)

Trustees considered the cost structure of each Fund relative to its Morningstar Peer Group.

The Trustees also considered the overall profitability of the Funds to KCM and examined the level of profits that could be expected to accrue to KCM from the fees payable under the Management Agreements, as well as the Funds' brokerage commissions and use of soft dollars by KCM. The Trustees also considered the profitability of each Fund before and after any distribution costs borne by KCM. These considerations were based on materials requested by the Trustees specifically for the Meeting, as well as the presentations made by KCM over the course of the year.

In reviewing the Morningstar 15(c) materials, the Board noted the Institutional Class shares of the Buffalo Funds operate under a unitary fee structure whereby many of the Funds' ordinary operating expenses are paid by KCM out of its advisory fee rather than paid directly by the Funds. The Board noted the difficulty of comparing the Buffalo Funds to non-unitary fee funds and observed that the advisory fee comparison in the Board materials which used the management fee excluding the fees paid by KCM to Fund Services under a master servicing agreement, and referred to below as the net management fee, was the most appropriate. The Board also noted the net expense ratio used in the Morningstar comparative data excludes any Rule 12b-1 fees imposed by other funds.

Buffalo Discovery Fund. The Trustees noted the Buffalo Discovery Fund's net management fee of 0.55% fell within the first quartile of the Morningstar Peer Group and was below the median and average of 0.70%. The Trustees further noted the net expense ratio of 1.01% for the Buffalo Discovery Fund fell in the third quartile of the Morningstar Peer Group, above the median of 0.84% and average of 0.89%, which fell into the third quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the Discovery Fund had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo Dividend Focus Fund. The Trustees noted the Buffalo Dividend Focus Fund's net management fee of 0.50% fell within the second quartile of the Morningstar Peer Group and was below the median of 0.55% and average of 0.56%, which fell at the bottom of the third quartile. The Trustees further noted the net expense ratio of 0.93% for the Buffalo Dividend Focus Fund fell into the third quartile of the Morningstar Peer Group, above the

median of 0.87% and average of 0.81%, which fell into the second quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded while KCM was not realizing profits in connection with its management of the Dividend Focus Fund, KCM maintained adequate profit levels to support its services to the Fund from the revenues of its overall investment advisory business.

Buffalo Early Stage Growth Fund. The Trustees noted the Buffalo Early Stage Growth Fund's net management fee of 1.00% fell within the fourth quartile of the Morningstar Peer Group and was above the median of 0.83% and average of 0.85%, which fell into the third quartile. The Trustees further noted the net expense ratio of 1.44% for the Buffalo Early Stage Growth Fund fell at the top of the fourth quartile of the Morningstar Peer Group, above the median of 1.00% and average of 1.03%, which fell into the third quartile. The Trustees noted that based on information provided by KCM, the Early Stage Growth Fund would more closely align with a micro-cap category, but Morningstar does not have such a category and the Fund is therefore included in the small growth category. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the Early Stage Growth Fund had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo Flexible Income Fund. The Trustees noted the Buffalo Flexible Income Fund's net management fee of 0.55% fell within the second quartile of the Morningstar Peer Group and was below the median of 0.60% and average of 0.59%, which fell within the second quartile. The Trustees further noted the net expense ratio of 1.01% for the Buffalo Flexible Income Fund fell within the fourth quartile of the Morningstar Peer Group, above the median of 0.73% and average of 0.76%, which fell within the third quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the Flexible Income Fund had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo Growth Fund. The Trustees noted the Buffalo Growth Fund's net management fee of 0.50% fell at the top of the first quartile of the Morningstar Peer Group, below the median and average of 0.65%. The Trustees further noted the net expense ratio of 0.87% for the Buffalo Growth Fund fell within the second quartile of the Morningstar Peer Group, below the median of 0.92% and

140

(Unaudited)

average of 0.90%, which fell within the second quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the Growth Fund had not been, and currently was not excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo High Yield Fund. The Trustees noted the Buffalo High Yield Fund's net management fee of 0.55% fell into the second quartile of the Morningstar Peer Group, below the median of 0.56% and average of 0.57%, which fell in the third quartile. The Trustees further noted the net expense ratio of 1.01% for the Buffalo High Yield Fund fell within the fourth quartile of the Morningstar Peer Group, above the median of 0.75% and average of 0.77%, which fell within the third quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the High Yield Fund had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo International Fund. The Trustees noted the Buffalo International Fund's net management fee of 0.55% was the lowest of the Morningstar Peer Group, below the median of 0.70% and average of 0.73%, which fell within the third quartile. The Trustees further noted the net expense ratio of 1.02% for the Buffalo International Fund fell within the fourth quartile of the Morningstar Peer Group, above the median of 0.88% and average of 0.86%, which fell within the second quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the International Fund was not excessive and that KCM maintained adequate profit levels to support its services to the Fund.

Buffalo Large Cap Fund. The Trustees noted the Buffalo Large Cap Fund's net management fee of 0.50% fell at the top of the first quartile of the Morningstar Peer Group, below the median of 0.65% and average of 0.66%, which fell at the bottom of the third quartile. The Trustees further noted the net expense ratio of 0.88% for the Buffalo Large Cap Fund fell within the second quartile of the Morningstar Peer Group, below the median of 0.97% and average of 0.95%, which fell within the second quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded while KCM was not realizing profits in connection with its management of the Large Cap Fund, KCM maintained adequate profit levels to support its services to the Fund from the revenues of its overall investment advisory business.

Buffalo Mid Cap Fund. The Trustees noted the Buffalo Mid Cap Fund's net management fee of 0.55% fell within the first quartile of the Morningstar Peer Group, below the median of 0.73% and average of 0.76%, which fell within the third quartile. The Trustees further noted the net expense ratio of 0.97% for the Buffalo Mid Cap Fund fell within the second quartile of the Morningstar Peer Group, below the median of 1.03% and average of 1.05%, which fell within the third quartile. Based on a profitability analysis prepared by KCM, the Trustees concluded while KCM was not realizing profits in connection with its management of the Mid Cap Fund, KCM maintained adequate profit levels to support its services to the Fund from the revenues of its overall investment advisory business.

Buffalo Small Cap Fund.

The Trustees further noted the net expense ratio of 0.96% for the Buffalo Small Cap Fund was equal to the Morningstar Peer Group median and below the average of 0.99%, which fell within the third quartile. The Trustees further noted the annual management fee is subject to reduced fees paid on assets in excess of certain levels. Based on a profitability analysis prepared by KCM, the Trustees concluded that KCM's profit from sponsoring the Small Cap Fund had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support its services to the Fund.

The Trustees concluded that each Fund's expenses and the management fees paid to KCM were fair and reasonable in light of the comparative performance, expense and management fee information. The Trustees further concluded that KCM's profit from sponsoring the Funds had not been, and currently was not, excessive and that KCM maintained adequate profit levels to support the services to the Funds.

4. Extent of Economies of Scale as the Funds Grow

The Trustees compared each Fund's expenses relative to its peer group and discussed realized and potential economies of scale. In considering the economies of scale for each Fund, the Board considered that the Buffalo Funds' Institutional Class shares operate under a unitary fee structure whereby many of the Funds' ordinary operating expenses are paid by KCM out of its advisory fee rather than being paid directly by the Funds.

141

(Unaudited)

Buffalo Discovery Fund. The Trustees reviewed the structure of the Buffalo Discovery Fund's management fee and total expense ratio and considered whether the Fund was large enough to generate economies of scale for shareholders or whether economies of scale would be expected to be realized as Fund assets grow (and if so, how those economies of scale were being or would be shared with shareholders).

The Trustees noted the Buffalo Large Cap Fund's management fee structure did not contain any breakpoint reductions as the Fund's assets grow in size, but that the feasibility of incorporating breakpoints would continue to be reviewed on a regular basis.

Buffalo Mid Cap Fund. The Trustees reviewed the structure of the Buffalo Mid Cap Fund's management fee and total expense ratio and considered whether the Fund was large enough to generate economies of scale for shareholders or whether economies of scale would be expected to be realized as Fund assets grow (and if so, how those economies of scale were being or would be shared with shareholders). The Trustees noted the Buffalo Mid Cap Fund's management fee structure did not contain any breakpoint reductions as the Fund's assets grow in size, but that the feasibility of incorporating breakpoints would continue to be reviewed on a regular basis.

Buffalo Small Cap Fund. The Trustees reviewed the structure of the Buffalo Small Cap Fund's management fee and total expense ratio and considered whether the Fund was large enough to generate economies of scale for shareholders or whether economies of scale would be expected to be realized as Fund assets grow (and if so, how those economies of scale were being or would be shared with shareholders). The Trustees further noted the Buffalo Small Cap Fund's management fee structure

contained breakpoint reductions as the Fund's assets grow in size.

The Trustees concluded that the current fee structure for each Fund was reasonable and reflected a sharing of economies of scale between KCM and each Fund at each Fund's current asset levels.

5. Benefits Derived from the Relationship with the Funds

The Trustees considered the direct and indirect benefits that could be received by KCM from its association with the Funds. The Trustees examined the brokerage and commissions of KCM with respect to the Funds. The Trustees concluded that the benefits KCM may receive, such as greater name recognition, growth in separate account management services, greater exposure to press coverage, or increased ability to obtain research or brokerage services through the use of soft dollars, appear to be reasonable, and may benefit the Funds through growth in assets.

CONCLUSIONS

Based on their review of the foregoing information, the Trustees found the terms of the Management Agreements were fair and reasonable and in the best interests of each Fund. As such, the Trustees, including a majority of the Independent Trustees, approved the continuation of the Management Agreements for an additional one-year term ending November 30, 2024.

Ernst & Young LLP ("EY") served as the independent registered public accounting firm for the Funds for the fiscal year ended March 31, 2023. On January 18, 2024, the audit committee of the Board of Trustees approved the engagement of Cohen & Company Ltd. (“Cohen”) as independent registered public accounting firm of the Funds for the fiscal year ending March 31, 2024.

The audit committee of the Board of Trustees engaged Cohen on February 22, 2024, as the independent registered public accounting firm to audit the Funds’ financial statements for the fiscal year ending March 31, 2024.

The report of EY on the Funds’ financial statements for the fiscal year ended March 31, 2023, did not contain an adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principle.

In connection with the audits of the Funds’ financial statements for the fiscal year ended March 31, 2023, there were no disagreements with EY on any matters of accounting principles or practices, financial statement disclosure, or auditing scope and procedures which, if not resolved to the satisfaction of EY, would have caused EY to make reference to the matter in their report.

There were no “reportable events” as that term is described in Item 304(a)(1)(v) of Regulation S-K.

During the fiscal year ended March 31, 2023 and during the subsequent interim period through February 22, 2024, neither the registrant, nor anyone acting on its behalf, consulted with Cohen on behalf of the Funds regarding the application of accounting principles to a specified transaction (either competed or proposed), the type of audit opinion that might be rendered on the Funds’ financial statements, or any matter that was either: (i) the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K and the instructions thereto; or (ii) “reportable events,” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Trust provided EY with a copy of the disclosure it is making herein in response to Item 304(a) of Regulation S-K and requested that EY furnish to the Trust a copy of their letter addressed to the Securities and Exchange Commission (the “SEC”) pursuant to Item 304(a)(3) of Regulation S-K, stating whether EY agrees with the statements made by the Trust in this N-CSR filing. A copy of EY’s letter to the SEC dated June 7, 2024 is attached as Exhibit 13.1a.

(b)

Certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Furnished herewith.
