Is Rambus Destined for Greatness?

Investors love stocks that consistently beat the Street without getting ahead of their fundamentals and risking a meltdown. The best stocks offer sustainable market-beating gains, with robust and improving financial metrics that support strong price growth. Does Rambus (NASDAQ: RMBS  ) fit the bill? Let's take a look at what its recent results tell us about its potential for future gains.

What we're looking for
The graphs you're about to see tell Rambus' story, and we'll be grading the quality of that story in several ways:

  • Growth: Are profits, margins, and free cash flow all increasing?
  • Valuation: Is share price growing in line with earnings per share?
  • Opportunities: Is return on equity increasing while debt to equity declines?
  • Dividends: Are dividends consistently growing in a sustainable way?

How we got here and where we're going
Things don't look good at all for Rambus today. The memory chipmaker mustered only one out of seven possible passing grades, and even that was granted more on a technicality than on real improvement. Over the past couple of years, Rambus' bottom line and free cash flow have both collapsed into negative territory due to a combination of weakness in the PC market and high operational costs including R&D and legal activities. Can Rambus overcome these challenges? Let's take a closer look at what the company might have planned for the future.

Over the last decade, Rambus filed a number of lawsuits against semiconductor companies for violating its memory and chip technology patents, but it has lost notable legal battles to Micron (NASDAQ: MU  ) and SK Hynix. The company filed a $4 billion antitrust lawsuit against these two rivals, but courts ultimately the claim that Micron and Hynix colluded to fix the prices of DRAM undercut Rambus-developed RDRAM. It certainly did not help that Rambus intentionally destroyed evidence in the lawsuit.

However, Rambus has still managed to obtain some victories of varying quality. The company agreed to settle a long-running patents infringement lawsuit earlier this year by entering a patent licensing agreement with LSI that will run through 2018. Rambus also settled a patent dispute over memory-chip technology by signing a five-year patent licensing agreement with SK Hynix for $240 million. The company also inked a comprehensive agreement to settle pending disputes with STMicroelectronics, which will allow ST to use Rambus' memory and interface technologies across a wide range of products. Microsemi has also inked an agreement with Rambus to secure CRI design tools  that will allow Microsemi to create tamper-resistant semiconductors and chips. Rambus has also expanded its business relationships with Freescale Semiconductor, which will allow Freescale to employ Rambus' resistive memory technology in its embedded applications.

The net outcome of these various battles appears to be negative: the company recently cut 15% of its total workforce , which will allow it to save between $30 million to $35 million annually. Rambus also divested its display-patent assets to a subsidiary of Acacia Research Corporation.

Rambus did retain its LED-lighting patent portfolio, which it continues to develop as an avenue of future growth. In the past few months, the company has introduced in-lamp color adjustment technology , and also launched LED bulbs with built-in MicroLens optical technology , which boast features such as broad dimmer compatibility and effective thermal management. This diversification could be a reaction to Micron's recent acquisition of Elpida, which signals tougher competition in the memory-chip market that has long been Rambus' bread-and-butter. However, LED lighting is no less competitive, and several larger manufacturing concerns have been building their capabilities in this field for years. There may not be much space for Rambus to find a foothold.

Putting the pieces together
Today, Rambus has few of the qualities that make up a great stock, but no stock is truly perfect. Digging deeper can help you uncover the answers you need to make a great buy -- or to stay away from a stock that's going nowhere.

    The NPE model is a risky one, as it depends too much on licensing, which not only has a limited life, but needs to be fought in the courts at huge expense because it is a one against many fight. For Rambus, the transformation to production in the LED lighting arena may be its savior.
