Markets Review
U.S. small/mid cap equities demonstrated notable resilience during the first quarter of 2026, navigating a volatile macroeconomic and geopolitical backdrop more effectively than large cap stocks. While broader U.S. equity markets declined amid rising oil prices, renewed inflation concerns, and escalating conflict in the Middle East, small- and mid-caps modestly outperformed, supported by improving earnings momentum, attractive relative valuations, and greater exposure to domestically focused areas of the economy. The Russell 2500 Index gained 2.04% for the quarter, contrasting with a -4.33% decline in the S&P 500 and marking a rare instance in which small- and mid-caps posted gains during a down quarter for large caps. Performance leadership favored value oriented and domestically focused companies, while mega cap growth stocks experienced valuation pressure as investors rotated away from highly concentrated market leadership. The quarter was shaped by heightened macro uncertainty, though U.S. economic growth remained positive, with GDP advancing at an annualized pace near 2.4% and labor markets showing early signs of stabilization despite a modest rise in unemployment. Inflation remained slightly above the Federal Reserve’s 2% target and intensified late in the quarter following a surge in energy prices tied to the conflict in Iran and disruptions to oil flows through the Strait of Hormuz. Monetary policy remained unchanged with the federal funds rate holding steady at 3.50%-3.75% while continuing to signal the potential for a rate cut later in 2026; an environment that tends to benefit smaller companies with higher floating rate debt exposure as financial conditions ease.
Stylistically, value stocks outperformed their growth counterparts during the quarter as the Russell 2500 Value Index returned 4.77% compared to the -3.52% return of the Russell 2500 Growth index. Performance was highly concentrated, as Energy outperformed the Russell 2500 Index by over 36%, and the top five stocks contributed over 100% of the benchmark’s return. From a factor perspective, higher quality companies outperformed lower quality companies during the quarter. Factors that had the strongest payoffs were low variability, low leverage, low volatility, ROIC, ROE, and profitability.
At the sector level, there was mixed performance between cyclical and defensive stocks. The best performing sectors were Energy (+38.72%), Consumer Staples (+6.73%), and Industrials (+6.52%), while the worst performing sectors were Financials (-6.10%), Consumer Discretionary (-5.30%), and Health Care (-3.29%).

Performance Review
For the first quarter of 2026, the Aristotle Small/Mid Cap Equity Composite generated a total return of 3.37% net of fees (3.51% gross of fees), outperforming the 2.04% total return of the Russell 2500 Index. Both security selection and allocation effect positively contributed to performance. The largest contributors to relative performance was security selection in Information Technology and Financials coupled with an overweight allocation to Information Technology and an underweight allocation to Consumer Discretionary. Security selection in Industrials and Health Care (a combination of stocks we owned alongside not owning biotechnology) coupled with underweight allocations to Utilities and Communication Services detracted from performance.

CONTRIBUTORS
Advanced Energy Industries (AEIS), is a provider of power electronics conversion products. The stock extended a strong multi-quarter rally fueled by earnings revisions, AI‑related infrastructure spending, and improving semiconductor capital expenditure trends. We maintain our position, as we believe the company’s exposure to AI‑driven semiconductor and data‑center demand should continue to drive shareholder value.
Ciena (CIEN), is an optical networking equipment manufacturer for telecommunications and web scale network operators. The stock benefited from expectations for an eventual optical networking recovery, driven by accelerating data consumption, AI‑related traffic growth, and the company’s leadership in high‑speed coherent optical solutions and software driven networking. We believe the company has benefitted from strong demand for bandwidth given its differentiated product portfolio and history of technological innovation, which has produced strong operating results and shareholder value creation.
DETRACTORS
SanDisk (SNDK), engages in the development, manufacture, and provision of storage devices and solutions based on NAND flash technology. Its products include solid state drives, memory cards, and USB flash drives. The stock rallied during the quarter and was up 168% on improving memory cycle sentiment and AI‑driven storage demand. The portfolio did not own the position which resulted in a drag on relative performance versus the benchmark.
Huron Consulting Group (HURN), is a provider of technology, data, and analytics solutions to Healthcare, Education, and corporate clients. The company reported strong results and handily beat analyst expectations. Despite that, shares sold off amid market sentiment around AI potentially cannibalizing their business model which we believe is overly pessimistic. We maintain a position, as we believe the company may continue to benefit from durable demand, expanding margins, and secular growth tied to digital and regulatory complexity in their end markets over the long term.

BUYS/ACQUISITIONS
Casella Waste Systems (CWST), is a provider of solid waste management and recycling services. The company offers exposure to a resilient, recurring revenue waste management business operating in capacity constrained Northeast markets, where owned landfill and transfer assets create high barriers to entry and support pricing power. The company’s vertically integrated footprint and disciplined tuck‑in acquisition strategy enhance route density and cost synergies, supporting steady margin improvement, while stable contracted volumes and favorable long‑term industry dynamics underpin a clear path to further margin expansion and long‑term capital appreciation.
Envista Holdings (NVST), is a global manufacturer and marketer of dental consumables, equipment, diagnostics, orthodontic solutions, and treatment technologies, offering a comprehensive portfolio that includes implants, imaging systems, treatment software, and aligners. Dental care represents a structurally attractive, non‑discretionary end market, supported by aging demographics, increasing oral health awareness, and sustained demand for restorative and aesthetic procedures. Through its broad product portfolio and service capabilities, the company offers exposure to a growing, recurring‑revenue dental market, with meaningful margin recovery potential as management executes on operational initiatives, at an attractive valuation.
SELLS/LIQUIDATIONS
Alight (ALIT), is a provider of cloud-based integrated digital human capital and business solutions. The position was liquidated due to fundamentals deteriorating and an uncertain strategic outlook.
Ciena (CIEN), is an optical networking equipment manufacturer for telecommunications and web scale network operators. The position appreciated since purchase, resulting in its sale to redeploy capital to new opportunities with better risk/reward potential.
Outlook
We remain constructive on the long-term outlook for the small/mid-cap segment of the U.S. market. Valuations remain compelling relative to large caps, with the Russell 2500 Index trading near the lower end of its historical range, while earnings are beginning to reaccelerate. Consensus estimates point to small cap earnings growth surpassing large cap growth by late 2026, which should be supportive of small/mid cap allocations. Incremental increase in M&A activity, improving domestic manufacturing trends supported by reshoring and infrastructure investment, and a more favorable regulatory and tariff backdrop should provide longer term tailwinds for the asset class. Near term, we remain cautious as geopolitical risks, including the Iran conflict and related inflationary spillovers, may contribute to elevated volatility. Separately, mid-term election uncertainty has historically been associated with increased market volatility but has often given way to more durable small cap recoveries following the election cycle.
Positioning
Our current positioning is a function of our bottom-up security selection process and our ability to identify what we view as attractive investment candidates, regardless of economic sector definitions. Overweights in Information Technology and Materials are mostly a function of our underlying company specific views rather than any top-down predictions for each sector. Conversely, we continue to be underweight in Consumer Discretionary, as we have been unable to identify what we consider to be compelling long-term opportunities that fit our discipline given the rising risk profiles of many retail businesses and a potential deceleration in goods spending following a period of strength. We are also underweight in Real Estate as the sector has elevated interest rate sensitivity, refinancing risk, and structural challenges in segments such as office and retail, combined with generally weaker balance sheets, leading us to seek what we consider to be more attractive reward to risk opportunities. Given our focus on long-term business fundamentals, our patient investment approach and low portfolio turnover, the strategy’s sector positioning generally does not change significantly from quarter to quarter. However, we may take advantage of periods of volatility by adding selectively to certain companies when appropriate.

All investments carry a certain degree of risk, including the possible loss of principal. Investments are also subject to political, market, currency and regulatory risks or economic developments. International investments involve special risks that may in particular cause a loss in principal, including currency fluctuation, lower liquidity, different accounting methods and economic and political systems, and higher transaction costs. These risks typically are greater in emerging markets. While Large-capitalization companies may have more stable prices than smaller, less established companies, they are still subject to equity securities risk. In addition, large-capitalization equity security prices may not rise as much as prices of equity securities of small-capitalization companies. Securities of small- and medium-sized companies tend to have a shorter history of operations, be more volatile and less liquid.
