OSI Systems (OSIS) has just reported its Q3 2026 results, with quarterly revenue of US$464.1 million and basic EPS of US$2.31, set against trailing twelve month revenue of about US$1.8 billion and basic EPS of US$9.11 that reflect the broader earnings run rate. Over recent periods the company has seen revenue move from US$419.8 million and EPS of US$2.26 in Q2 2025 to US$464.1 million and EPS of US$2.31 in Q2 2026. At the same time, trailing twelve month EPS stepped up from US$7.96 to US$9.11 as revenue increased from US$1.65 billion to about US$1.80 billion. This puts the focus squarely on how efficiently that top line is now dropping through to margins.

With the latest earnings numbers on the table, the next step is to see how they line up with the key narratives around OSI Systems's growth, profitability and risk profile that investors have been following over the past year.

TTM margin ticks up to 8.5%

• Over the trailing twelve months, OSI Systems converted US$1.80b of revenue into US$153.1 million of net income, which works out to an 8.5% net margin compared with 8.1% a year earlier.
• Analysts' consensus view links this higher margin with a shift toward service-based and software platforms. However, the current 8.5% margin still sits below the 10.6% margin analysts expect in a few years, so:
  • Consensus narrative points to expanding service contracts and platforms like CertScan as key margin drivers, while the healthcare division's weak margins and execution risk across divisions could keep the gap between 8.5% today and future margin expectations in focus.
  • The 13.9% earnings growth rate over the last year supports the idea of improving profitability, but the modest step up in margin suggests execution on higher value offerings and divisional turnarounds remains an important watchpoint for that story.

Earnings growth outpaces revenue

• Trailing twelve month earnings grew 13.9% year over year, compared with revenue growth from US$1.65b to US$1.80b and a net profit margin move from 8.1% to 8.5%, which points to profit growing faster than the top line over this period.
• Bulls argue that government driven security demand and record backlog can sustain this earnings strength, and the recent numbers partly back that up while also highlighting pressure points:
  • The 5 year earnings growth rate of 15.1% and the latest 13.9% annual earnings growth sit ahead of the forecast 6.2% annual revenue growth, which supports the bullish focus on earnings power even if sales growth is more moderate.
  • At the same time, earnings are expected to grow about 13.6% per year compared with a higher expected market growth rate, and ongoing weakness in the healthcare segment plus reliance on large government contracts means the recent earnings outperformance has to be viewed alongside areas where that bullish case is more exposed.

On top of that, bulls point to the mix of record backlog, higher margin services, and consistent earnings growth as a reason to dig deeper into their thesis for OSI Systems, which you can do by checking out the 🐂 OSI Systems Bull Case.

Attractive P/E with weak cash coverage

• OSI Systems trades on a trailing P/E of 25.3x against a peer average of 81x and a US Electronic industry average of 29.8x, while the current share price of US$234.74 sits about 11.1% below a DCF fair value of roughly US$263.99.
• Bears focus on leverage and cash flow coverage as a counterweight to that valuation, and the risk summary gives that view some grounding:
  • The key flagged risk is that debt is not well covered by operating cash flow, which means that even with a P/E below peers and a discount to DCF fair value, the balance sheet and cash generation remain central to how comfortable an investor might feel with that apparent discount.
  • Critics also highlight dependence on large government contracts and long payment cycles, so the combination of weaker cash coverage and concentrated customers can matter just as much as P/E comparisons or the gap between US$234.74 and the roughly US$263.99 DCF value.
