GeneDx: Strong Fundamentals Intact As
Market Misreads Test Volume Dip

GeneDx Holdings Corp. (NASDAQ:WGS) delivers precision medical diagnostics through advanced genomic sequencing, data science, and a proprietary rare disease dataset that grows and benefits from over 800,000 sequenced genomes and exomes. The company is focused on pediatric outpatient and neonatal ICU settings, with potential for broader expansion. Its services support early diagnosis, treatment planning, and rare disease drug discovery, targeting conditions such as epilepsy and autism. 

This report reviews Q1 2025 results and the subsequent stock pullback. For detailed background, refer to our prior publications:

Following GeneDx's Q1 2025 earnings, the market reaction has been disproportionately focused on a sequential dip in test volumes in Whole Exome and Genome sequencing. However, we believe this concern is overblown when viewed in context, and the underlying fundamentals of the business remain strong.

GeneDx delivered a strong first quarter with total revenues of $87.1 million, ahead of expectations of $79.5 million, and EPS of $0.27 versus the $0.04 estimate, as per Seeking Alpha.

The main business and valuation driver, Whole Exome and Genome (WEG) revenues, were up 62% year-over-year while testing volume for the segment grew by 24%.

Guidance was raised to a range of $360 to $375 million, up from $350 to $360 million.

It was a strong first quarter, exceeding the top-line guidance issued by the company.

The prior year had not encountered such a dip, although a similar Q1 dip occurred in 2023 followed by volume acceleration in subsequent quarters.

Management cited seasonality, severe winter weather, and one fewer business day as contributing factors. Importantly, the company reiterated its full-year volume growth expectation of at least 30%, driven by second-half contributions from new initiatives.

We do not believe a sequential volume dip indicates a material change in business prospects. Despite the Q1 seasonal softness, volumes nearly matched Q4 levels, which is the strongest quarter, and the company delivered a meaningful revenue beat.

On the pricing front, the company experienced a modest 2% sequential decline for WEG tests, after adjusting Q4 2024 revenues down for a $5.8 million settlement of pending claims.

However, this decrease is not reflective of underlying pricing pressure.

Upon further discussion with the company, the dip reflects a seasonal pattern at the beginning of the year when deductibles are reset, resulting in a higher share of claims being paid directly by the patients. Importantly, on a year-over-year basis, WEG pricing improved 31%, from $2,652 per test in Q1 2024, underscoring the longer-term pricing strength.

Management reiterated its confidence in an ongoing multi-year trajectory of reimbursement improvements, supported by diminishing denial rates and the introduction of higher-value offerings.

Consistent pricing improvements will be another key lever for sustained revenue growth this year, especially as volume re-accelerates during the year.

The company continues to execute steadily on its strategic roadmap and is well-positioned to capitalize on its early-mover advantage in genomics diagnostics. In the outpatient setting, GeneDx is steadily expanding its service lines with the frequent addition of new clinical indications. 

Meanwhile, the inpatient business — particularly in Neonatal Intensive Care Units (NICU) — represents a significant and underpenetrated opportunity. Management expects this segment to contribute meaningful revenues in 2026 and perhaps earlier, supported by foundational work currently underway.

Additionally, GeneDx's integration with Epic Systems, a widely used hospital patient management platform, is expected to streamline adoption and expand its footprint across inpatient settings. The recent acquisition of Fabrinet also enhances the company's capabilities in AI-powered test interpretation service, extending its reach into facilities with in-house sequencing operations and further broadening the addressable market.

Management has consistently guided to stronger performance in the second half of the year, with at least 30% volume and revenue growth in 2025.

GeneDx's competitive edge lies in its proprietary rare disease dataset and interpretation platform. The company is leveraging this asset to expand into data interpretation-as-a-service, a high-margin, capital-light growth vector that can significantly expand market reach.

An untapped and rapidly expanding market, compelling high-value offerings, and a unique rare disease dataset are some key elements that enhance the company's strategic positioning and widens the competitive moat.

GeneDx's Q1 performance demonstrated operational strength despite seasonal headwinds.
We believe the post-earnings selloff is an overreaction and view the pullback as a temporary dislocation in a longer-term uptrend. Second-quarter results should help restore confidence with progress on volume and pricing metrics. If momentum continues, GeneDx may also attract interest from strategic acquirers.

As a high-multiple growth company, GeneDx must proactively align expectations with investor community and minimize surprises like those seen this quarter.

We had partially reduced the position in both the Prudent Healthcare and Prudent Small Cap model portfolios ahead of earnings as part of risk management and re-balancing due to the strong performance of the stock over the past year. The Prudent Small Cap portfolio maintains a position in GeneDx, and future adjustments will not be announced.

As always, investors should conduct independent research and remain mindful of the risks inherent in small-cap growth investing.
