Metrics are mathematically derived from official filings.
Steady Revenue Acceleration
STERIS's revenue growth has accelerated from 7.3% in 2026Q1 to 9.9% in 2026Q2, with 2027Q1 maintaining 7.3% growth, indicating sustained demand for medical specialties, as per recent quarterly filings.
The sequential acceleration in revenue growth from 2025Q4's 32.6% (likely a one-time boost) to a more normalized 7-10% range suggests organic demand is solid. The 2027Q1 growth of 7.3% on a larger base indicates durability, though the deceleration from 2026Q2's 9.9% warrants monitoring. This growth appears broad-based, not reliant on a single quarter.
Gross Margin Expansion with Mix Shift
Gross margin improved from 40.2% in 2024Q4 to 45.8% in 2027Q1, a 560 basis point expansion, driven by operational efficiencies and product mix, as reported in financial statements.
The gross margin trajectory shows a clear upward trend, with 2027Q1 at 45.8% versus the peer average of around 48%, indicating room for further improvement. The 2024Q4 dip to 40.2% appears anomalous, possibly due to one-time costs, but the subsequent recovery suggests structural gains. This margin expansion is a key driver of profitability and may reflect pricing power or cost controls.
Operating Leverage Driving Margin Gains
Operating margin expanded from 14.5% in 2025Q1 to 19.1% in 2027Q1, with operating income growing faster than revenue, indicating strong operating leverage, based on reported quarterly data.
Operating income grew from $185.5M in 2025Q1 to $285.8M in 2027Q1, a 54% increase, while revenue grew only 15% over the same period. This disproportionate growth suggests SG&A efficiency, as SG&A remained relatively flat around $350M despite revenue increases. The 2027Q1 SG&A is reported as zero, which may be a data artifact, but the trend in prior quarters shows disciplined cost management.
Earnings Quality Supported by Tax and SBC
Net income quality appears solid with EPS growth outpacing revenue growth, but stock-based compensation averaging $20M per quarter and a tax rate anomaly in 2024Q4 warrant scrutiny, as per SEC filings.
EPS growth has been robust, with 2027Q1 EPS of $2.04 up 14% year-over-year, while net income grew 37% from 2025Q1. However, SBC of $45M in 2026Q4 is notably higher than other quarters, which could dilute future EPS. The 2024Q4 net loss of -$1.4M appears to be a one-time tax or impairment charge, given the subsequent recovery, but investors should monitor for recurring non-operating items.
COGS Efficiency and R&D Stability
COGS as a percentage of revenue declined from 59.8% in 2024Q4 to 54.2% in 2027Q1, while R&D remained stable around 2% of revenue, indicating cost discipline, as reported in financial statements.
The reduction in COGS ratio is a primary driver of gross margin expansion, suggesting improved manufacturing efficiency or favorable input costs. R&D spending has been consistent at roughly $25-29M per quarter, reflecting a steady investment in innovation without significant escalation. SG&A, when reported, has been flat around $350M, indicating overhead control despite revenue growth.
2024Q4: A Turning Point
The 2024Q4 quarter marked a clear inflection, with revenue dropping 19.4% and a net loss, but subsequent quarters show a strong recovery, indicating a temporary disruption, based on reported figures.
The 2024Q4 data shows a sharp decline in revenue and a net loss, likely due to a one-time event such as a divestiture or restructuring. The following quarter (2025Q1) saw revenue rebound to $1.3B and net income of $145.4M, suggesting the disruption was transient. This inflection highlights the company's resilience and the importance of distinguishing one-time items from underlying trends.
What Could Invalidate the Base Case
Despite strong margin expansion, the 2024Q4 net loss and elevated SBC in 2026Q4 raise questions about earnings sustainability, while revenue growth may decelerate if healthcare capital spending slows, as per reported data.
Short-sellers might argue that the 2024Q4 net loss indicates underlying volatility, and the subsequent recovery could be flattered by easy comparisons. The elevated SBC of $45M in 2026Q4 suggests potential dilution that could pressure EPS growth. Additionally, the reliance on healthcare capital spending makes revenue growth vulnerable to budget cycles, and the gross margin, while improved, still lags peers like Waters, implying less pricing power. Investors should monitor whether the operating margin expansion is sustainable or if it reflects one-time cost savings.
