Factors Affecting Performance [Text Block]

How did the Fund perform in the last year?

The Champlain Small Company Fund (Advisor Shares) returned 13.72% for the year-to-date period ending December 31, 2024, which was ahead of the 11.54% return for Russell 2000 Index and trailed the 23.81% return for the Russell 3000 Index.

Absolute returns and relative outperformance versus the Russell 2000 Index were driven by this Fund’s financial holdings due to strong stock selection in insurance, banks, and the capital markets industry. Late in the year, the election of a new president and political administration initially prompted a strong positive reaction from financial sector stocks, which are expected to benefit from lower regulatory burdens, an improved M&A landscape, and possibly even lower corporate taxes. In aggregate, this Fund’s consumer holdings underperformed those of the Russell 2000 Index as weak selection in staples offset the positive allocation effect from being overweight staples and strong selection in discretionary. In staples, MGP Ingredients declined nearly 60% in 2024 due to challenges and unpredictability in the spirits segment. After consumers and distributors loaded up on inventory during and immediately after the pandemic, demand quickly slowed when inflation spiked. The Fund’s industrials and materials holdings outperformed as strong performance in materials outweighed weaker results in industrials. Our process-based exclusion of the more cyclical industries in these sectors, particularly construction & engineering and aerospace & defense, has been a persistent headwind all year. In the technology sector stock selection in the software industry was weak. Additionally, our lack of exposure to Super Micro Computer and MicroStrategy Incorporated was a notable relative performance headwind. Conversely, Pure Storage was this Fund’s top absolute and relative contributor as shares rose by over 70% during the year. In health care, this Fund’s holdings underperformed as stock selection in the equipment & supplies industry was a meaningful detractor. Neogen and CONMED were each among the Fund’s largest absolute and relative detractors for the period. Neogen has seen subpar growth due to their food safety customers’ lower volumes while the company’s acquisition of 3M’s food safety business two years ago led to integration challenges and some lost market share. CONMED has been facing competitive products that investors are currently worried about, but we believe the competitive risks are manageable and are incorporated into our Fair Value estimate.

Small cap stocks seem relatively attractive compared to large cap companies, especially high-quality small cap companies such as those owned by this Fund that do not face a meaningful debt refunding burden or tough comparison to prior results that were substantially aided by unprecedented stimulus tailwinds.

Champlain’s investment team is committed to a Scout’s Mindset that will react to new information in a manner that aims to prevent mistakes and losses from overwhelming the expected favorable relative returns our investment process is likely to produce over time.

Factors Affecting Performance [Text Block]

How did the Fund perform in the last year?

The Champlain Mid Cap Fund (Advisor Shares) returned 5.96% for the year-to-date period ending December 31, 2024, which trailed the 15.34% return for Russell Midcap Index and the 23.81% return for the Russell 3000 Index.

The Fund’s health care holdings underperformed the Russell Midcap Index due to the overweight of, and stock selection within equipment & supplies. Despite shares rebounding somewhat in the fourth quarter, DexCom was this Fund’s largest absolute detractor. Shares have been pressured from uncertainty surrounding the market opportunity and pricing strategy for its over-the-counter continuous glucose monitor device. The company also reduced guidance in the third quarter, which surprised investors. The Fund’s information technology holdings underperformed during the period as the positive allocation effect from the overweight of the software industry was not enough to offset weak selection in the same industry. Much of the weakness in software was due to the Fund’s lack of exposure to Palantir Technologies (+340%) and AppLovin (+712%). In industrials, this Fund’s holdings trailed those of the benchmark as stock selection in machinery was weak. The process-based exclusion of the more cyclical industries in this sector, particularly airlines and construction & engineering, was also a persistent headwind. Conversely, the lack of exposure to the materials sector was a notable tailwind. The Fund’s consumer holdings underperformed in 2024 due to our perennial overweight of staples and stock selection in discretionary. Brown-Forman was among the Fund’s largest absolute and relative detractors; shares fell by 32% during the year as the company contends with both sluggish demand from the whiskey category and the whiskey-specific risk from potential tariffs. In financials, this Fund’s holdings modestly outperformed those of the Russell Midcap Index due to the overweight of the insurance industry and our position in Toast. Toast reported a meaningful improvement in profitability and guided to strong margins going forward, announced a $250 million share repurchase program, and committed to lower stock compensation expenses. The outcome of the U.S. election in November initiated a strong positive reaction from financial stocks, which are expected to benefit from lowered regulatory burdens, an improved M&A landscape, and possibly even lower corporate taxes. As a result, the Fund’s lack of exposure to consumer finance, asset management and investment banking was a relative headwind.

Mid cap stocks seem relatively attractive compared to large cap companies, especially high-quality mid cap companies such as those owned by this Fund that do not face a meaningful debt refunding burden or tough comparison to prior results that were substantially aided by unprecedented stimulus tailwinds.

Factors Affecting Performance [Text Block]

How did the Fund perform in the last year?

The Champlain Strategic Focus Fund (Institutional Shares) returned 4.40% for the year-to-date period ending December 31, 2024, which trailed the 22.10% return for Russell Midcap Growth Index and the 23.81% return for the Russell 3000 Index.

This fund’s information technology holdings underperformed versus the Russell Midcap Growth Index due to stock selection in software and IT services. While Fund holdings MongoDB, Okta, and Zscaler all lagged materially, much of this sector’s underperformance was due to strong returns from two companies that this Fund does not hold – Palantir Technologies (+340%) and AppLovin (+712%). The Fund’s lack of exposure to semiconductors was helpful; and Pure Storage was the Fund’s top absolute and relative contributor by a considerable margin. In industrials, the Fund’s holdings underperformed due to the overweight of machinery and stock selection in electrical equipment. Rockwell Automation and Fortive each detracted on a relative basis. The Fund’s lack of exposure to the aerospace & defense and construction & engineering industries also detracted on a relative basis. In health care, this Fund’s overweight of the life sciences tools & services industry along with stock selection in equipment & supplies drove underperformance. DexCom was the Fund’s largest detractor on an absolute and relative return basis. Shares have been pressured from uncertainty surrounding the market opportunity and pricing strategy for its over-the-counter continuous glucose monitor device. The company also reduced guidance in the third quarter, which surprised investors. The Fund’s financial holdings underperformed during the period, driven by stock selection in insurance and the Fund’s underweight of the financial services and capital markets industries. Within insurance, Everest Group was the primary driver of underperformance as the company lagged both industry peers and the broader market as investors grappled with the increasing likelihood of a fourth quarter casualty insurance reserve charge, following an in-depth reserve audit. Finally, the Fund’s consumer holdings outperformed as the overweight of discretionary and underweight of staples both benefited relative returns. Tractor Supply was the top performing stock in the sector and we sold the position in November as shares traded within proximity of our estimate of Fair Value. Cosmetic retailer, Ulta Beauty, had a nice recovery in the fourth quarter as early reads on holiday spending appear better than feared. We are likely past the worst of the competitive pressures from Sephora rolling out at almost 1,000 Kohl’s and appreciate management’s continued use of excess cash flow to buy back almost $1 billion in stock annually.
