Alger Small Cap Focus Fund Amy Zhang | “Natera is a specialty diagnostics laboratory that provides high-value genetic testing across three core franchises: reproductive health, oncology led by Signatera, and transplant monitoring. These tests are built on the company's proprietary cell-free DNA liquid biopsy platform, enabling highly sensitive detection from a blood sample. Shares contributed positively after the company reported strong fiscal third-quarter earnings, with management commentary pointing to revenue and margin performance that exceeded expectations on the back of higher test volumes and favorable reimbursement dynamics—particularly within the Signatera franchise—alongside another increase to full-year 2025 revenue and margin guidance. BSD Analysis: Natera is evolving from a prenatal testing leader into a broader precision medicine platform anchored by Signatera in oncology. The recurring-use nature of minimal residual disease testing improves lifetime value versus one-off diagnostics. Clinical adoption is accelerating faster than reimbursement normalization, creating near-term margin pressure. Gross margins are improving as scale builds, but profitability remains a medium-term goal. Natera's data advantage is becoming a moat as longitudinal datasets grow. The upside hinges on Signatera becoming standard of care. This is a category-defining diagnostics company still early in its earnings curve.” | BULL | Q4 2025 Jan 8, 2026 | View Pitch |
Alger Spectra Fund Patrick Kelly, Dan Chung, Ankur Crawford | “Natera is a specialty diagnostics laboratory that provides high-value genetic testing across three core franchises: reproductive health, oncology led by Signatera, and transplant monitoring. These tests are built on the company's proprietary cell-free DNA liquid biopsy platform, enabling highly sensitive detection from a blood sample. Shares contributed positively after the company reported strong fiscal third-quarter earnings, with management commentary pointing to revenue and margin performance that exceeded expectations. Results were driven by higher test volumes and favorable reimbursement dynamics, particularly within the Signatera franchise. Management also raised full-year 2025 revenue and margin guidance again. BSD Analysis: Beyond prenatal testing, Natera's long-term value increasingly rests on oncology surveillance and transplant monitoring. Signatera's ability to track disease recurrence in real time creates new clinical workflows, not just one-off tests. This recurring-use model improves lifetime customer value. While losses persist, incremental margins are moving in the right direction. Clinical adoption is outpacing reimbursement expansion, which remains a key catalyst. Competition exists, but Natera's data depth is a moat. This is a platform-in-the-making, not just a diagnostics vendor.” | BULL | Q4 2025 Jan 8, 2026 | View Pitch |
Parnassus Growth Equity Fund Andrew Choi & Shivani Vohra | “Natera continued to outperform during the quarter as adoption of its flagship diagnostic product accelerated. Positive clinical data and improving reimbursement visibility bolstered investor confidence, reinforcing the company's leadership in non-invasive genetic testing. Demand momentum across oncology and women's health supported strong revenue growth and validated the long-term commercial potential of its platform. BSD Analysis: Natera operates at the forefront of genetic testing with strong positions in oncology and women's health. Clinical data quality is the core asset. Adoption continues to expand as testing becomes standard of care. Reimbursement dynamics create volatility. Cash burn concerns weigh on sentiment. Investors fixate on losses instead of clinical embedment. Scale improves unit economics over time. This is diagnostics with real workflow integration. Science drives the moat.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Alger Weatherbie Specialized Growth Fund H. George Dai, Joshua D. Bennett | “Natera is a specialty diagnostics laboratory that provides high-value genetic testing across three core franchises: reproductive health (including non-invasive prenatal testing for chromosomal conditions such as trisomy 13, 18, and 21), oncology (led by Signatera, which measures circulating tumor DNA to assess treatment response and detect molecular residual disease and cancer recurrence), and transplant (tests used to monitor organ rejection). These tests are built on the company's proprietary cell-free DNA liquid biopsy platform, enabling highly sensitive detection from a blood sample. Shares contributed positively after the company reported strong fiscal third-quarter earnings, with management commentary pointing to revenue and margin performance that exceeded expectations on the back of higher test volumes and favorable reimbursement dynamics—particularly within the Signatera franchise—alongside another increase to full-year 2025 revenue and margin guidance. BSD Analysis: Natera is a leader in cell-free DNA testing, with flagship products in non-invasive prenatal testing and oncology monitoring. Its Signatera platform is becoming a standard tool for detecting minimal residual disease, expanding Natera beyond diagnostics into longitudinal cancer management. Gross margins are improving as volumes scale, though profitability remains a work in progress. Clinical data continues to reinforce the platform's value, driving adoption among oncologists. Reimbursement and test mix are the main swing factors. Natera is evolving from a testing company into a data-rich precision medicine platform. High growth, but still execution-sensitive.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Carillon Eagle Mid Cap Growth Fund Eric Mintz, Christopher Sassouni, David Cavanaugh | “Natera is a diagnostics company that provides preconception and prenatal genetic testing services, with its flagship Signatera oncology test driving growth. In the latest quarter, growth of Signatera volumes exceeded consensus estimates, prompting management to raise its revenue growth guidance. Profitability continues to strengthen with rising gross margins and sustained positive free cash flow. With Signatera's impressive total addressable market, we believe Natera remains well positioned for long-term expansion. BSD Analysis: Natera's moat is clinical credibility in genetic testing where accuracy directly affects medical decisions. Once physicians trust a test, switching is slow and reputationally risky. Growth has been strong, but reimbursement and payer scrutiny are the real long-term governors of returns. Volume growth doesn't automatically translate into margin expansion, especially as tests commoditize at the edges. Litigation and regulatory complexity add noise that investors often underestimate. The company still spends like a growth biotech while being judged like a diagnostics platform. The bull case is broader guideline inclusion and payer alignment across oncology and women's health. The bear case is margin disappointment once growth normalizes. Natera wins on science—but must prove it can win on economics.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
