    OSI Systems (OSIS) As New Contracts And Earnings Optimism Revive The Value Debate

    Listen to the news

    Recent commentary around OSI Systems (OSIS) has focused on its value characteristics and earnings outlook, at a time when demand for its security screening and optoelectronic products is supported by new government contracts and sector investment.

    At a share price of US$200.49, OSI Systems has seen short term share price momentum fade, with the 90 day share price return down 7.48% and the year to date share price return down 21.55%. However, the 5 year total shareholder return of 113.04% points to a much stronger long run record. This helps explain why fresh government security contracts and an upcoming quarterly results call are drawing renewed attention to the valuation story.

    Spot opportunities with similar value characteristics by scanning our hand-picked list of 29 high quality undervalued stocks. These stocks share some of the same earnings and contract-driven themes as OSI Systems.

    OSI Systems looks like a solid operator in security and optoelectronics, yet the share price has slipped this year. Is that recent weakness giving you a genuine value entry, or just fair pricing catching up with reality?

    Most Popular Narrative: 28% Undervalued

    On the widely followed valuation narrative, OSI Systems screens as undervalued, with a fair value of $278.29 set against the last close at $200.49 and built off a detailed view of backlog, margins and earnings power.

    The main factor that has to go right is that OSI Systems continues to grow higher margin Security, RF and service revenues while sustaining the recent margin improvement in Healthcare. This would allow the whole group to support structurally higher profitability on its existing contract base.

    See why 5 investors see OSI Systems as 28% undervalued.

    Result: Fair Value of $278.29 (UNDERVALUED)

    Still, the OSI Systems narrative depends on Security revenues recovering from recent declines and on geopolitical delays not turning record backlog into slower and more uneven cash conversion.

    Another View: SWS DCF Says OSI Systems Is Overvalued
