Baron Health Care Fund Neal Kaufman | “We bought shares of Repligen Corporation, a life science tools supplier to the bioprocessing industry. The company benefits from strong positioning in monoclonal antibodies and fast-growing cell and gene therapy markets. Repligen's products are embedded in regulated workflows, creating high switching costs and recurring consumables revenue. The company is leveraging real-time process analytics and AI to build a data moat. We believe Repligen can double revenue over five years while expanding EBITDA margins by 1,000 basis points. BSD Analysis: Repligen sells critical components to bioprocessing workflows where failure is not tolerated. Its filtration and chromatography tools are embedded deep inside drug manufacturing, creating high switching costs. Growth slowed as biotech funding cooled, exposing the cyclicality beneath the quality. That doesn't erase the moat — it just resets expectations. Margins remain strong because the products are mission-critical. As biologics pipelines restart, demand snaps back fast. Capital discipline matters more now than expansion. This is not a biotech bet. It's life-sciences infrastructure with cyclical timing.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Conestoga SMid Cap Composite Derek Johnston | “RGEN supplies bioprocessing equipment and consumables used in biologic drug manufacturing. Shares rebounded strongly as evidence mounted that industry destocking had bottomed and order trends were stabilizing. Improved visibility into 2026 growth, combined with disciplined cost controls, drove operating leverage expectations higher. The market re-rated the stock as investors looked past near-term volatility and focused on RGEN's high-quality consumables mix, strong market positions, and long-term biologics growth tailwinds. BSD Analysis: Repligen supplies critical components for biologics manufacturing where switching suppliers is risky and expensive. Biotech funding slowdowns hit volumes, but they don't erase pipelines. Technical complexity creates pricing power most suppliers never see. Investors panic during destocking phases. But contamination risk keeps customers loyal. Margins reflect specialization, not scale hype. When biologics production restarts, demand rebounds sharply. Operating leverage cuts both ways. This is a life sciences tollbooth paused, not broken.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Conestoga Small Cap Composite Joe Monahan | “Repligen Corp. (RGEN) rebounded strongly as evidence mounted that industry destocking had bottomed and order trends were stabilizing. Improved visibility into 2026 growth, combined with disciplined cost controls, drove operating leverage expectations higher. The market re-rated the stock as investors looked past near-term volatility and focused on RGEN's high-quality consumables mix and long-term biologics growth tailwinds. BSD Analysis: Repligen sits upstream of biologics manufacturing, supplying components customers won't swap casually. Funding slowdowns hit volumes, but complexity protects relevance. Contamination risk keeps switching costs high. Margins reflect technical specialization. Investors panic over destocking cycles. But biologics pipelines keep growing. When production restarts, demand rebounds sharply. Operating leverage cuts both ways. This is a life sciences tollbooth paused, not broken.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Conestoga Mid Cap Composite Conestoga Capital Advisors, LLC | “Repligen Corp. (RGEN) was among the largest contributors as evidence mounted that bioprocessing destocking had bottomed. Order trends stabilized during the quarter, improving visibility into 2026 growth. Management's disciplined cost controls drove operating leverage expectations higher. Investors began to re-rate the stock as focus shifted away from near-term volatility toward Repligen's high-quality consumables mix and strong competitive positioning. We continue to view Repligen as a long-term beneficiary of biologics and advanced therapy growth. BSD Analysis: Repligen supplies mission-critical components for biologics manufacturing, sitting upstream of drug pipelines. Demand softened as biotech funding slowed, hurting volumes. But complexity in biologics keeps barriers high. Switching suppliers risks contamination and downtime. Margins reflect technical depth, not scale hype. Investors confuse cyclical destocking with secular erosion. As biologics rebound, Repligen benefits disproportionately. Operating leverage is meaningful. This is a life sciences tollbooth in a pause, not decline.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
