Earnings Growth Analysis

The company’s earnings growth has been influenced by the year-on-year improvement in gross margins from 84.60% to 84.70%. However the company’s overhead costs have prevented it from fully capitalizing on these gross margin improvements. In fact, the company’s operating margins (EBITDA margins) showed no improvement over the same period last year.

Gross Margin Trend

Companies sometimes sacrifice improvements in revenues and margins in order to extend friendlier terms to customers and vendors. Capital Cube probes for such activity by comparing the changes in gross margins with any changes in working capital. If the gross margins improved without a worsening of working capital, it is possible that the company’s performance is a result of truly delivering in the marketplace and not simply an accounting prop-up using the balance sheet.

Gross Margin History
Working Capital Days History

RMBS-US‘s gross margin improvement has not produced any big difference in its working capital. Working capital days are currently 349.51, compared to last year’s level of 286.59 days. This leads Capital Cube to conclude that the improvements in gross margins are likely from operating decisions and not trade-offs with the balance sheet.

Gross Margin Versus Working Capital Days


The company’s operating (EBIT) margins contracted from 23.81% to 23.38%. In spite of this, the company’s earnings rose. This was influenced primarily by one-time items, which improved pretax margins from 16.94% to 20.33%.
