Ariel Appreciation Fund John W. Rogers | “Bio-Rad Laboratories ($BIO), accounting for 3.0% of the strategy's assets, is a global life sciences instrumentation and clinical diagnostics equipment provider. The manager maintains a constructive bullish posture, predicated on the company's resilient core testing franchise, operational restructuring, and ongoing strategic dialogue with activist investor Elliott Investment Management to unlock corporate value. Economically, Bio-Rad benefits from an extensive installed base of proprietary diagnostic instruments that generates highly predictable, high-margin consumable reagent pull-through. Operational discipline, cost containment, and comprehensive operational restructuring programs are driving operating leverage, allowing margin expansion even during periods of cyclical softness in Chinese demand and university research budgets. Share repurchases further enhance free cash flow per share accretion. Key upside catalysts include formal capital allocation framework announcements stemming from activist engagement, sequential recovery in end-market biopharma spending, and restructuring cost savings realization. Risks to monitor include protracted weakness in academic lab budgets, end-market geopolitical friction in China, and execution slip-ups during organizational streamlining.” | BULL | Q3 2026 Oct 15, 2026 | View Pitch |
Ariel Fund John W. Rogers, Jr. | “Bio-Rad Laboratories ($BIO) develops, manufactures, and markets clinical diagnostics instruments and life sciences laboratory research systems, constituting 4.6% of the fund. The manager takes a constructive, bullish view based on the company's resilient organic revenue generation and strategic operational transformation. The investment thesis highlights significant potential for margin expansion through a structured corporate restructuring initiative aimed at optimizing overhead and streamlining operational disciplines. Capital allocation efficiency is poised to improve as the board actively engages with activist fund Elliott Investment Management to unlock value and optimize shareholder capital return programs. Key forward catalysts encompass multi-year operating margin expansion from operational restructuring and ongoing activist-driven capital allocation clarity. Downside risks involve sustained soft demand from Chinese research institutions and constrained academic spending environments.” | BULL | Q3 2026 Oct 15, 2026 | View Pitch |
AVI Global Trust Joe Bauernfreund | “Bio-Rad Laboratories ($BIO) is a life sciences and clinical diagnostics manufacturer that produces lab instruments, reagents, and test kits, while holding a non-consolidated 32% ownership stake in Sartorius AG. The manager initiated a position based on an extreme sum-of-the-parts dislocation where the market values Bio-Rad's core stub operations at an implied valuation of under $2 billion against roughly $430 million in expected annual EBITDA, essentially giving away high-quality operating cash flows for free due to accounting obscurity. The investment thesis combines high recurring revenue unit economics with significant potential for operating leverage. Bio-Rad operates a classic razor-and-blade model, generating over 70% recurring revenue across 12,000 sticky laboratory products where no individual customer represents more than 2% of sales. However, bloated administrative expenses have suppressed operating margins to approximately 12% versus peer levels in the high teens to 20s. Substantial upside exists if newly appointed operational leadership streamlines costs and closes the margin gap, while its underlying Sartorius holding compounds value at mid-teens returns on invested capital in biologics manufacturing. Key catalysts include an active restructuring campaign, external pressure from activist investor Elliott Management, and the scheduled 2028 dissolution of the controlling Sartorius family trust, which could place Sartorius in play for industry consolidation. Primary risks to monitor center on capital allocation risk under Schwartz family voting control, operational execution delays in the core diagnostic turnaround, and valuation vulnerability in Sartorius trading around 20x EV/EBITDA.” | BULL | Q3 2026 Oct 13, 2026 | View Pitch |
Ariel Focus Fund Ariel Investments, LLC | “Bio-Rad was repurchased by the fund because of its dominant market share in key life science categories and diversified global footprint. The company has growing operating margins and a high share of recurring revenues, positioning it well to capture growth in clinical diagnostics and biopharma.” | BULL | Q1 2026 Mar 31, 2026 | View Pitch |
Longleaf Partners Global Fund Ross Glotzbach | “Bio-Rad – Life-sciences companies Bio-Rad and Avantor combined to detract from our performance this year. We entered the year owning only Bio-Rad. The company got off to a rough start with a disappointing set of results compounded by large industry headwinds as a result of US government-driven research spending cutbacks. The good news on Bio-Rad was that it repurchased shares at a strong pace in the first half of the year and avoided large, value-destructive M&A. The company also showed operational improvement and should be in a better position to grow FCF in 2026 and beyond. BSD Analysis: Bio-Rad is a quietly dominant life sciences tools company with deep roots in diagnostics and research workflows. Demand cycles ebb with funding, but the installed base creates recurring consumables revenue that stabilizes cash flow. The company's technological depth makes it sticky in labs that don't like switching critical systems. Margin pressure has masked the durability of the model. Investors often compare Bio-Rad to faster-growing peers and miss its resilience. Long-term growth tracks scientific complexity, not funding headlines. This is a steady compounder hiding behind cyclical noise.” | BULL | Q4 2025 Jan 1, 2026 | View Pitch |
First Eagle Investments James Fellows | “Bio-Rad is a highly integrated leader in specialized niches of diagnostics and life sciences, benefiting from high barriers to entry and strong recurring revenue. The company possesses significant hidden asset value via a major equity stake in Sartorius and features highly aligned family leadership.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
First Eagle Investments James Fellows | “Healthcare has been out of favor in recent years, weighed down by post-Covid headwinds, but we find the highly regulated sector to be structurally attractive given growing demand and significant barriers to entry. With a market cap around $6.5 billion, Bio-Rad Laboratories is smaller than our typical investment, but the company dominates the niches it serves within the areas of life-science research and diagnostics. Vertical integration historically has resulted in strong recurring revenue for the company, and its diversified customer base has further supported stability. Notably, Bio-Rad maintains a one-third stake in German biopharma company Sartorius that has grown significantly since its purchase and provides Bio-Rad with an economic exposure beyond its core businesses. Founded in a Quonset hut in 1952 by a husband-wife pair of Cal Berkeley graduates and run by their son since 2003, Bio-Rad maintains a family orientation that aligns interests with shareholders and contributes to the long-term orientation we look for in management teams. BSD Analysis: Bio-Rad is a niche-dominant life sciences tools company with recurring revenue, high switching costs, and strong barriers to entry. The embedded value of its Sartorius stake adds hidden asset value not fully reflected in the share price. Healthcare's regulatory complexity favors incumbents with scale and expertise, supporting long-term cash flow durability. Family-led governance aligns capital allocation with long-term value creation. Upside catalysts include recovery in life science spending and monetization or revaluation of the Sartorius stake. Risks include prolonged funding pressure in research budgets.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Madison Mid Cap Fund Haruki Toyama, Andy Romanowich, Rich Eisinger | “Bio-Techne is a leader in the life sciences research market with a broad portfolio of products that are used to enable discoveries of new drugs, therapeutics, and diagnostics. Around 80% of the business is recurring revenues. We are encouraged by the new CEO's strategy to leverage the core business and expand the company's leadership position in protein research. Consternation surrounding the health of customer research spending gave us the opportunity to buy the stock at a discount to our estimate of intrinsic value. BSD Analysis: Bio-Techne sells mission-critical reagents and tools embedded deep in life sciences workflows. Biotech funding cycles create demand pauses, not customer churn. Validation and reproducibility requirements create high switching costs. Margins reflect specialization, not scale hype. Investors confuse destocking with decay. As research funding normalizes, volume snaps back quickly. The installed base quietly compounds consumables revenue. Operating leverage cuts both ways. This is picks-and-shovels science tested by patience.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Longleaf Partners Fund Southeastern Asset Management, Inc. | “Bio-Rad Laboratories, a healthcare products manufacturer, was a positive contributor after the company reported steadier earnings than the market expected in a difficult environment. This sets the company up for the ability to grow earnings in 2026 and beyond, more in-line with previous industry trends. The company's important investment in Sartorius has also shown encouraging year-over-year trends following a difficult couple of years, and we are getting closer to a period when both companies will have increased strategic flexibility. In the meantime, Bio-Rad continues to be a material share repurchaser with its nearly net cash balance sheet. BSD Analysis: Bio-Rad remains one of the most technically credible players in life-science tools, with IP depth in PCR, antibodies, and immunology that gives it a durable niche even in a sluggish funding environment. The company's operational reset is working — cost actions are lifting margins and the balance sheet is clean. End-market softness is real, but Bio-Rad's recurring consumables base keeps earnings more stable than bears admit. The market still prices BIO like a stalled instruments company, not a high-ROIC specialty tools provider with improving execution. As research spending normalizes, Bio-Rad looks positioned for a solid margin and sentiment rebound.” | BULL | Q3 2025 Oct 1, 2025 | View Pitch |
