Exhibit 99.1 PLX Technology, Inc. Reports Fourth Quarter and Fiscal Year 2005 Financial Results SUNNYVALE, Calif.--(BUSINESS WIRE)--Jan. 31, 2006--PLX Technology, Inc. (NASDAQ:PLXT): -- 19 Percent Sequential Quarterly Revenue Growth -- PCI Express Revenue Grows to More Than $2.2 Million -- Twelfth Consecutive Year of Pro Forma Net Income PLX Technology, Inc. (NASDAQ:PLXT) today announced financial results for the fourth quarter and fiscal year ended December 31, 2005. For the fourth quarter, PLX reported net revenues of $15.3 million, a 19 percent increase from the $12.9 million reported for the third quarter of 2005, and a 15 percent increase from the $13.3 million reported for the prior-year fourth quarter. Net revenues for the 2005 fiscal year were $54.6 million, a slight increase from the $54.4 million reported for the 2004 fiscal year. Net income for the fourth quarter of 2005, under U.S. generally accepted accounting principles (GAAP), which included the effect of acquisition-related costs, were $35,000, or $0.00 per share (diluted). This compared with net losses under GAAP of $0.5 million, or a loss of $0.02 per share (diluted), for the third quarter of 2005 and net losses under GAAP of $0.7 million, or $0.03 per share (diluted), for the prior-year fourth quarter. Net losses for the 2005 fiscal year were $1.7 million, or a loss of $0.06 per share (diluted), compared to net losses of $0.6 million, or a loss of $0.03 per share (diluted), for the 2004 fiscal year. Pro forma net income for the fourth quarter of 2005, which excluded the effect of acquisition-related costs, was $0.8 million, or $0.03 per share (diluted). This compared with pro forma net income of $22,000, or $0.00 per share (diluted), for the third quarter of 2005 and with pro forma net losses of $0.2 million, or a loss of $0.01 per share (diluted), for the prior-year fourth quarter. Pro forma net income for the 2005 fiscal year was $0.7 million, or $0.02 per share (diluted), compared with pro forma net income of $2.3 million, or $0.09 per share (diluted), for the 2004 fiscal year. A reconciliation between net income (loss) under GAAP and pro forma net income (loss) is provided in a table immediately below the Pro Forma Consolidated Statements of Operations. The Company's gross margin for the fourth quarter of 2005 was 64 percent, compared with 66 percent for the prior quarter. The decrease in gross margin as a percentage of sales was the result of a shift in the Company's product and customer mix. Operating expenses on a GAAP basis for the fourth quarter of 2005 were $9.9 million, compared with $9.2 million for the prior quarter. On a pro forma basis, which excludes acquisition-related costs of approximately $0.7 million and $0.5 million for the quarters ended December 31, 2005 and September 30, 2005, respectively, operating expenses were $9.2 million for the fourth quarter of 2005, compared with $8.6 million for the prior quarter. The sequential increase in operating expenses was due to higher compensation and benefit expenses as a result of higher headcount, increases in sales commissions to manufacturer's representatives as a result of higher revenues, and increases in professional fees due in part to the Company's year-end audit. The Company's balance sheet remained strong. On December 31, 2005, cash and total investments were $35.0 million, compared to $30.3 million at December 31, 2004. Additionally, there continues to be no debt. "In fiscal 2005 we achieved our twelfth consecutive year of pro forma net profit and added nearly $5 million in cash," said Mike Salameh, PLX Technology chief executive officer. "Fourth-quarter revenues grew sequentially by 19 percent, driven primarily by the growth of our PCI Express(TM) revenues, which surpassed $2.2 million. We also continued to build our leadership position in the PCI Express market by sampling our sixth PCI Express chip. Since we started sampling PCI Express in late 2004, we have shipped samples or development systems to more than 250 customers, up from the 200 in the third quarter. By introducing innovative products early in the industry-wide transition to PCI Express, we established a lead that we anticipate will result in continued total Company revenue growth. "We also grew our USB business by 14 percent over last quarter, based on our success in winning designs in PC peripheral and consumer electronics applications, and we expect continued growth in the first quarter of 2006. Furthermore, our legacy PCI business grew by six percent sequentially." Business Outlook The following statements are based on current expectations. The Company does not intend to update, confirm or change this guidance until its first-quarter earnings conference call, although it may provide additional detail regarding its guidance during today's scheduled call. -- Revenue for the first quarter of 2006 is expected to be between $16.2 million and $17.2 million, with approximately 13 percent to 15 percent of total revenues attributable to USB products and approximately 20 percent to 24 percent of total revenues attributable to PCI Express products. -- Gross margins are expected to be in the range of 62 percent to 65 percent. -- Operating expenses on a pro forma basis, which excludes acquisition-related costs and stock option expenses, are expected to be between $9.2 million and $9.5 million. Engineering expenses related to 0.13-micron chip development comprise a significant portion of total anticipated first-quarter expenses. The actual timing of the expenses will depend on the timing of actual mask and prototype fabrication. PLX(R) management plans to conduct a conference call today at 2:00 p.m. PST to discuss its fourth-quarter and 2005 fiscal-year financial results, as well as its first-quarter outlook. There will also be a live Webcast and a replay of the conference call available through the Investors section of the PLX Web site at http://www.plxtech.com/investors until February 7, 2006. The Webcast can also be accessed through www.ccbn.com. For the live Webcast, listeners should go to the PLX Web site at least 15 minutes before the event starts to download and install any necessary audio software. The archived Webcast is typically available one to two hours after the end of the live call. USE OF PRO FORMA FINANCIAL INFORMATION: In addition to reporting financial results in accordance with GAAP, PLX reports pro forma financial results. Pro forma net income (loss) and earnings (loss) per share exclude acquisition-related charges, such as amortization of deferred compensation, amortization and write-down of purchased intangible assets and in-process research and development charges. PLX's management believes that the presentation of pro forma financial results are useful to investors and other interested persons because, by excluding certain expenses the Company believes are not indicative of our core operating results, the users of the financial statements are provided with valuable insight into PLX's operating results. Further, these non-GAAP results are one of the primary indicators PLX's management uses for planning and forecasting future performance. In addition, PLX has consistently provided these pro forma measurements in previous earnings releases and believes that it is important to provide investors and other interested persons with a consistent basis for comparison between quarters. The method PLX uses to produce pro forma results is not computed according to GAAP, is likely to differ from the methods used by other companies and should not be regarded as a replacement for corresponding GAAP measures. Investors are encouraged to review the reconciliation of these pro forma financial measures to the comparable GAAP results, which is provided in a table immediately below the Pro Forma Consolidated Statements of Operations.
