THIRD QUARTER 2025

Letter to Investors

November 12, 2025

My fellow investors,

Lux Fund produced strong returns during the third quarter of 2025, appreciating 15.2%. We recognize another quarter of growing investor capital through a disciplined, diversified strategy of investing in what we believe to be the highest quality companies within the most rewarding segment of public equities.

Third-quarter performance was supported by acquisition offers for four of our portfolio holdings. Since inception, 14 of our companies have been acquired at premiums to their market value—an encouraging validation of our strategy. We’re optimistic about the relative return potential of smaller public equities and the attractive opportunities in this under appreciated market segment.

Third-quarter performance was supported by acquisition offers for four of our portfolio holdings. Recall our investment theses for these featured companies from previous letters:

Innovid
Logility
Olo

Despite market implications that the smallest public equities are inherently lower quality, our experience suggests otherwise. While the segment contains riskier businesses, it also offers the greatest potential for return. Our process, refined and proven over more than 20 years of aggregated experience managing institutional assets, combines quantitative modeling with thorough qualitative analysis to identify a diversified portfolio of durable, high-quality companies.

We intentionally avoid the riskiest companies, targeting investment in businesses we believe have sustainable growth opportunities, robust profitability profiles, attractive valuations and strong investor sentiment.

Our research indicates these companies outperform their counterparts. Over time, this approach has produced excess returns relative to small and micro cap benchmarks, demonstrating resilience across market cycles.

Throughout our careers, we have managed funds across all market capitalizations, yet our highest conviction lies in smaller companies—where inefficiencies and mispricings are most pronounced. Because large institutional investors often overlook this space, the micro cap market tends to be dominated by less sophisticated participants. For our investors, Lux Fund fills this gap, complementing their traditional asset allocations with exposure to an area of the market poised for meaningful alpha generation.

Lux Fund complements a diversified portfolio by providing rare exposure to the market’s smallest and least accessible companies.

Among actively managed small and micro cap strategies, Lux Fund’s results since inception reflect clear leadership. In addition to delivering strong performance, we continually evaluate the investor experience and the operational quality of our business to ensure we uphold the highest professional standards for the institutions and families we serve. Your feedback remains vital to our ongoing improvement, and we welcome your thoughts.

We express our deepest gratitude to you and your family as we finish the year. Thank you for the opportunity to serve you.

Sincerely,

J.P. Gurnee, CFA
Portfolio Manager

Portfolio Outlook

Micro cap stocks trade at a discount to large caps, reflecting misplaced skepticism toward the smallest public companies. In contrast, many of these businesses are not inferior but mispriced—only to be acquired later at substantial premiums.

HISTORICAL ACQUISITION PREMIUM OF SMALL CAPS

Historically, the acquisition of small companies by large companies has contributed to the higher relative returns in small and micro cap equity investments versus their larger counterparts. A report published in the March 2024 issue of Journal of Financial and Quantitative Analysis analyzed the impact of acquisition activity to the small cap public equity asset class.

In summary, investments in small and micro cap companies enjoy greater benefits from acquisition premiums relative to large cap companies.

Further, Lux Fund’s investment process to date has identified more than its fair share of acquisition opportunities: year to date in 2025, nine of Lux Fund’s holdings received acquisition offers, equating to approximately 10% of the portfolio, with average acquisition premium of 50%. Over the same period only 3.5% of the broader micro cap equity market received acquisition offers.

OUR OUT-OF-CONSENSUS CASE AGAINST ADVERSE SELECTION

We continue to see quality assets within the space trading at significant discounts and expect acquisitions to be a tailwind to Lux Fund’s strategy going forward. Here are some of the quality assets we’re currently invested in that we see as potential acquisition targets:

  • AngioDynamics

    AngioDynamics produces a variety of medical devices. We believe the company’s product offering in the interventional cardiology space represents potentially best in class therapy which will enable continued share gains from larger competitors. We believe the company’s current attractive valuation creates an opportunity for an accretive acquisition and market share consolidation by a large medical device competitor.

  • Mitek Systems

    Mitek Systems provides software supporting 90%+ of mobile check deposits in the United States. Formerly the subject of acquisition rumors in 2018, we believe the company is fundamental stronger today despite trading for a similar valuation. We are encouraged by the recent appointment of CEO Ed West, who oversaw the sale of Cardtronics to NCR in 2021. Prior to Cardtronics, West was CFO of Delta Airlines. We see Mitek as a strong acquisition candidate for a financial technology company or a private equity firm given its strategic position in banking technology and associated strong cash flow generation.

  • National Research Corporation

    National Research Corporation provides critical healthcare services industry data. The business currently trades at a significant discount to the precedent transactions of a key competitor. The company’s management team has significant ownership in the business and we believe will maximize shareholder value. On a related note, we are encouraged by the appointment of CEO Trent Green, who will draw on experience as the former leader of Amazon’s healthcare business, One Medical.

  • UroGen Pharma

    UroGen Pharma provides oncology therapies in high unmet need treatment settings. We believe the company’s recent Zusduri approval, combined with a healthy revenue base from Jelmyto, collectively present a compelling acquisition target for a large pharma company.

Recent acquisitions at premium valuations affirm the quality of public micro-cap equities, even amid persistent discounts. Lux Fund remains uniquely positioned to benefit from this enduring trend.

Position Changes

  • New positions are initiated in the fund when they are attractive per LuxβetaTM (quantitative review) and validated through LuxαlphaTM (qualitative analysis). The fund initiated new positions in the following companies during the quarter:

    908 DEVICES

    BANDWIDTH

    CORE LABORATORIES

    DELCATH SYSTEMS

    FARMERS NATIONAL BANC

    JAKKS PACIFIC

    KARAT PACKAGING

    MAGNERA

    METROPOLITAN BANK HOLDING

    NUVATION BIO

    STONERIDGE

    TRUSTCO BANK

    TUCOWS

    UNITED FIRE GROUP

    WEAVE COMMUNICATIONS

  • Positions are sold from the fund when their LuxβetaTM profile deteriorates, the company develops significant off model, appreciates out of the micro cap asset class, or the company is acquired. The fund sold positions in the following companies during the quarter:

    FRANKLIN COVEY

    INTERNATIONAL MONEY EXPRESS (received acquisition offer)

    NERDWALLET

    OLO (received acquisition offer)

    OMNIAB

    POTBELLY (received acquisition offer)

    TITAN INTERNATIONAL

    SOLARIS ENERGY INFRASTRUCTURE

    SUPERIOR GROUP OF COMPANIES

    VIRTRA

    Y-MABS THERAPEUTICS (received acquisition offer)

  • Featured New Positions

    908 DEVICES provides chemical analysis tools globally in over 50 countries. The company serves a vast array of end markets including drug enforcement agencies, customs agencies, corrections and rehabilitation organizations, fire departments, and pharmaceutical and industrial manufacturers. The company provides both the tools and associated products enabling a predictable base of recurring revenues. In March 2025, the company announced the transformational divestiture of its desktop diagnostics division in order to focus on the handheld market. We expect the business to accelerate in 2026 and beyond based on a slate of upcoming product launches. We believe funding associated with the One Big Beautiful Bill Act may serve as a tailwind given its commitments to the U.S. Customs and Border Protection agency and other organizations which frequently use 908’s devices. We believe the company’s stock overly discounts future growth prospects owing to its association with the life science tools industry which recently has faced headwinds. We believe CEO Kevin Knopp’s expertise in founding and selling businesses, previously in founding a business which was ultimately sold to Thermo Fisher Scientific, may be relevant experience for 908 to draw on in the future.

  • Featured New Positions

    BANDWIDTH provides the cloud communication backbone underpinning leading voice and messaging services via a portfolio of telecom licenses and bandwidth. The company provides the underlying network infrastructure supporting Zoom, Google Voice and Microsoft Teams. Bandwidth’s network is a unique strategic asset which was built over decades in concert with regulators and would likely take years to replicate, establishing a significant barrier to entry. Further, its customers have limited interest in vertically integrating and displacing Bandwidth given the likelihood of incremental FCC scrutiny. We believe emerging agentic AI tools have the potential to drive increased demand for voice and messaging services over the coming years. Regardless of the pace of AI application development, we expect the mid-term election cycle in 2026 will be a tailwind to Bandwidth’s messaging business, as has been the case historically. We believe the company’s valuation overly discounts its significant competitive advantages and strong cash generation.

  • Featured New Positions

    TUCOWS is a technology services conglomerate providing domains services, telecom software and fiber services. The company’s registrar services generate a steady stream of cash flow by leasing domains to small businesses through a network of 35,000 resellers including Shopify, Squarespace and WordPress. The company’s cloud-based telecom billing and provisioning software business is growing market share as its competition failed to invest in transitioning services to the cloud. The company’s challenges in Ting Fiber have been an overhang on the business, however, Tucows has made significant progress in reducing Ting’s operating expenses and capital intensity. We see Tucows as undervalued as investor concern over Ting related debt obligations distracts from strong profit generation in domain services and telecom software. We believe Tucows’ domain services and telecom software are potentially worth more than the current market value of the entire business.
