SUNNYVALE, Calif. — (BUSINESS WIRE) — January 26, 2015 — Rambus Inc. (NASDAQ: RMBS), the innovative technology solutions company that brings invention to market, today reported financial results for the fourth quarter and year ended December 31, 2014.

GAAP Financial Results:

Revenue for the fourth quarter of 2014 was $72.0 million, up 3% on a sequential basis from the third quarter of 2014 primarily due to higher contract revenue. As compared to the fourth quarter of 2013, revenue was down 2% primarily due to lower royalty revenue from Samsung and NVIDIA, offset by the royalty revenue from Qualcomm and Micron Technology.

Revenue for the year ended December 31, 2014 was $296.6 million, which was up 9% over the prior year period, primarily due to the license agreements signed with SK hynix, Micron Technology, Nanya Technology Corporation and Qualcomm, partially offset by lower royalty revenue from Samsung and NVIDIA.

Total operating costs and expenses for the fourth quarter of 2014 were $54.5 million, 1% lower than the previous quarter and 19% lower than the fourth quarter of 2013. Fourth quarter operating costs and expenses of $54.5 million included $3.5 million of stock-based compensation expenses and $6.3 million of amortization expenses. In comparison, total operating costs and expenses for the third quarter of 2014 of $55.2 million included $3.4 million of stock-based compensation expenses and $6.7 million of amortization expenses. Total operating costs and expenses for the fourth quarter of 2013 were $67.2 million, which included $3.1 million of stock-based compensation expenses, $9.7 million of impairment of long-lived assets, $2.2 million of restructuring charges, $7.5 million of amortization expenses and $1.5 million of retention bonus expense from acquisitions. The change in total operating costs and expenses in the fourth quarter of 2014 as compared to the third quarter of 2014 was primarily due to recognition of a one-time gain in the fourth quarter from sale of intellectual property, partially offset by an increase in prototyping costs. The change in total operating costs and expenses in the fourth quarter of 2014 as compared to the fourth quarter of 2013 was primarily attributable to impairment of long-lived assets and restructuring charges in the fourth quarter of 2013, gain from sale of intellectual property in the fourth quarter of 2014 and lower retention bonus expense from acquisitions partially offset by higher cost of sales due to increased sale of lighting products.

Total operating costs and expenses for the year ended December 31, 2014 were $221.2 million, 11% lower than the year ended December 31, 2013. The year ended December 31, 2014 operating costs and expenses of $221.2 million included $14.7 million of stock-based compensation expenses, $26.6 million of amortization expenses and $2.5 million of retention bonus expense from acquisitions. This is compared to total operating costs and expenses for the year ended December 31, 2013 of $249.0 million, which included $15.0 million of stock-based compensation expenses, $17.8 million of impairment of goodwill and long-lived assets, $5.5 million of restructuring charges, $9.0 million one-time reversal of accrued SK hynix and Micron related litigation costs, $28.9 million of amortization expenses and $10.4 million of retention bonus expense from acquisitions. The change in total operating costs and expenses was primarily attributable to impairment of goodwill and long-lived assets and restructuring charges in 2013 and lower retention bonus expense from acquisitions, partially offset by higher cost of sales due to increased sale of lighting products and as a result of the one-time reversal of accrued SK hynix related litigation costs in the second quarter of 2013.
