Polynovo (STU:MFJ) Operating Margin % Explanation
Just like Gross Margin %, it is important to see a company maintains its operating margin over time. Among the same industry, a company with higher operating margin is more efficient in its operation. It is also more stable during industry slowdown or recessions. Peter Lynch prefers those with higher margins than those with lower margins.
Be Aware
Operating Margin % can be manipulated by adjusting the rate of depreciation, depletion and amortization (DDA).
If a company is facing competition, its Operating Margin % may decline. Often the Operating Margin % declines well before the company's Revenue or even profit decline. Therefore, Operating Margin % is a very important indicator of whether the company is facing problems.
For instance, by 2012, Nokia (NOK)'s problems were well known and its stock had lost more than 90% of its market value since 2007. But Nokias Operating Margin % had already been in decline since 2002, although its Earnings per Share (Diluted) were still rising. Investors who paid attention to Operating Margin % would have avoided this huge loss. The same can be said for Research-in-Motion (RIMM).
Therefore, Operating Margin % is a very important screening filter for GuruFocus. GuruFocus's Buffett-Munger screener requires that the profit margin is either consistent or expanding. The Model Portfolio of the Buffett-Munger screener has outperformed the market every year since inception in 2009.

Polynovo earns most of its revenue from US sales of its NovoSorb Biodegradable Temporizing Matrix, or NovoSorb BTM. The product is a patented biodegradable synthetic scaffold to support the regeneration of the dermis when lost through surgery, trauma, burns, or other causes of tissue loss. Once the product is applied to a wound, it takes a few weeks for the dermal layer to fully integrate within the polymer scaffold before a clinician can delaminate the outer layer. A small wound would then close either naturally or with a dressing, while a larger wound would close through a split-skin graft or alternative product such as Avita's RECELL. NovoSorb BTM then slowly degrades to harmless byproducts which are fully absorbed in roughly 18 months.
