SiRF Technology Holdings, Inc. (Nasdaq: SIRF), a leading provider of GPS-enabled silicon and premium software location platforms, today reported unaudited financial results for its fourth quarter and year ended December 31, 2006.


Net revenue in the fourth quarter of fiscal 2006 was $74.2 million, an increase of 37 percent from $54.3 million reported in the fourth quarter of 2005. Net revenue in fiscal 2006 was $247.7 million, an increase of 50 percent from $165.1 million in fiscal 2005. Gross margin in the fourth quarter of 2006 was 55.3 percent, as compared to 54.5 percent in the fourth quarter of 2005. Gross margin in fiscal 2006 was 55.6 percent, as compared to 55.4 percent in fiscal 2005.


Beginning in the fourth quarter of fiscal 2006, SiRF determined that due to business circumstances it could no longer reliably estimate royalty revenues for sales by certain licensees. As such, SiRF began recognizing all royalty revenues based solely on royalties reported by licensees during the quarter. This change in timing of recognizing royalty revenue was made prospectively and had an initial one-time effect of reducing royalty revenues recorded in the fourth quarter of fiscal 2006.


Net income for the fourth quarter of fiscal 2006 was $9.1 million or $0.16 per diluted share based on 56.1 million weighted average shares outstanding. This compares with net income of $10.2 million or $0.19 per diluted share based on 55.2 million weighted average shares outstanding in the fourth quarter of fiscal 2005. The decrease in net income for the fourth quarter of fiscal 2006 as compared to the fourth quarter of fiscal 2005 is primarily attributable to increased employee stock compensation expense as a result of the adoption of Statement of Financial Accounting Standard 123R, Share-Based Payment (SFAS No. 123R) on January 1, 2006, as well as increased acquisition-related contingent payments and compensation expense related to share-based payments associated with SiRF's acquisitions. These increased expenses were partially offset by a one-time research and development tax credit recognized in the fourth quarter of fiscal 2006. SiRF recognized $3.4 million in research and development tax credits as a result of the reinstatement of the federal research and development tax credit that was signed into law in December 2006 with retroactive effect to the beginning of 2006. Of the $3.4 million tax credit recorded in the fourth quarter of fiscal 2006, approximately $2.6 million related to the first nine months of the fiscal year. In addition, during the fourth quarter of fiscal 2005, SiRF recognized a one-time charge related to acquired in-process research and development associated with the acquisition of Impulsesoft, with no similar charge during the fourth quarter of fiscal 2006.


Net income for fiscal 2006 was $2.4 million or $0.04 per diluted share based on 56.0 million weighted average shares outstanding. This compares with net income of $30.0 million or $0.56 per diluted share based on 53.6 million weighted average shares outstanding in fiscal 2005. The decrease in net income for fiscal 2006 as compared to fiscal 2005 is primarily attributable to the same reasons as the decrease for the fourth quarter of fiscal 2006 as compared to the fourth quarter of fiscal 2005, as well as an increase in one- time charges related to acquired in-process research and development associated with the acquisition of TrueSpan of $13.3 million during the first quarter of fiscal 2006. In fiscal 2005, SiRF recognized cumulative one-time benefits of approximately $6.8 million associated with previously unrecognized income tax assets related to research and development tax credit benefits available for the 1997 - 2004 years, an acquisition-related tax benefit and the reversal of a litigation settlement obligation with no similar benefits recorded during fiscal 2006.


SiRF reports net income (loss) and basic and diluted net income (loss) per share in accordance with GAAP and additionally on a non-GAAP basis. Non-GAAP net income, where applicable, excludes the effect of amortization of acquisition-related intangibles, employee stock compensation expense, acquired in-process research and development, expenses related to acquisition-related contingent payments, benefits related to acquisition-related tax benefits, the reversal of a litigation settlement obligation and certain one-time benefits related to research and development tax credits. Non-GAAP net income for the fourth quarter of fiscal 2006 was $15.7 million or $0.28 per diluted share, as compared to non-GAAP net income of 12.2 million or $0.22 per diluted share for the fourth quarter of fiscal 2005. Non-GAAP net income for the fourth quarter of fiscal 2006 excludes $1.1 million in amortization of acquisition-related intangibles, $7.3 million in employee stock compensation expense, $0.8 million of expenses related to acquisition-related contingent payments and a one-time tax benefit of approximately $2.6 million for the first nine months of the fiscal year related to research and development tax credits, which were recognized in the fourth quarter as a result of the reinstatement of the federal research and development tax credit. Non-GAAP net income for the fourth quarter of fiscal 2005 excludes $1.6 million in amortization of acquisition-related intangibles, $1.7 million in employee stock compensation expense, $0.9 million of acquired in-process research and development and an acquisition-related tax benefit of $2.3 million. Weighted average shares outstanding used in computing diluted non-GAAP net income per share for the fourth quarter of fiscal 2006 were 56.1 million, compared to 55.2 million for the fourth quarter of fiscal 2005. Refer to the itemized reconciliation between net income on a GAAP basis and non-GAAP basis for the fourth quarter of fiscal 2006 and 2005 below.


Non-GAAP net income for fiscal 2006 was $50.3 million or $0.90 per diluted share, as compared to non-GAAP net income of $36.4 million or $0.68 per diluted share for fiscal 2005. Non-GAAP net income for fiscal 2006 excludes $5.2 million in amortization of acquisition-related intangibles, $26.2 million in employee stock compensation expense, $3.2 million of expenses related to acquisition-related contingent payments and a one-time charge of $13.3 million for acquired in-process research and development. Non-GAAP net income for fiscal 2005 excludes $5.6 million in amortization of acquisition-related intangibles, $5.8 million in employee stock compensation expense, a one-time charge of $1.7 million for acquired in-process research and development, tax benefits of $2.3 million from acquisition-related tax credits, $3.2 million from research and development tax credits resulting from a research and development tax credit study for cumulative unrecorded tax benefits for the years 1997 - 2004, and a one-time reversal of a litigation settlement obligation of $1.2 million. Weighted average shares outstanding used in computing diluted non-GAAP net income per share for fiscal 2006 were 56.0 million, compared with 53.6 million for fiscal 2005. Refer to the itemized reconciliation between net income on a GAAP basis and non-GAAP basis for fiscal 2006 and 2005 below.


Total cash, cash equivalents and short-term investments were $170.2 million at December 31, 2006, compared with $117.9 million at December 31, 2005. Long-term investments were $26.4 million at December 31, 2006, compared with $20.8 million at December 31, 2005.


"Demand for products with SiRF GPS was very strong at the retail level in Q4 resulting in an exceptional quarter for SiRF. We have recorded record revenues, shipments and operating income plus a strong order backlog for Q1," said Dr. Michael Canning, President and CEO.


Q4'2006 Highlights and Business Outlook:


The holiday season was quite strong for the portable navigation devices with other market segments also showing healthy growth. Consumer response to both enhanced functionality, as well as attractively priced portable navigation systems from our customers was extremely positive. Some of the quarter's highlights include:


-- SiRFstarIII based portable navigation devices were highlighted in


holiday promotions in US and Europe with sale prices hitting sub $200


mark for entry level products;


-- A broad range of SiRFstarIII based products were available at


mainstream retailers from major suppliers in the portable navigation


market, including Garmin, Magellan, Mio, Navman and TomTom;


-- Magellan, a leading provider of consumer GPS systems, ramped up volumes


on a range of products based on the SiRFstarIII architecture;


-- Nokia entered the portable navigation device market with SiRFstarIII


based Nokia 330 system;


-- Sony launched two new personal navigation devices (PND) (NV-U51 & NV-


U71T) based on SiRFstarIII in Europe; and


-- Sanyo entered the US PND market with the launch of SiRFstarIII based


EasyStreet NVM-4030 system.


We also see many positive developments in the wireless market with multiple operators announcing deployment of location based services, based on GPS-enabled mobile phone platforms, giving us further confidence in the ramp up of this market. Following the unveiling of T-Mobile MDA compact III GPS smart phone, at the IFA show in September, many new handsets with built-in GPS or with GPS accessories are either being deployed or going through operator interoperability testing (IOT) at major operators.


-- In October, Cingular Wireless, the largest wireless carrier in the


United States, launched its first generally available location-based


service (LBS), TeleNav GPS Navigator. This service is supported on


multiple handsets through SiRFstarIII based TeleNav GPS Receiver.


-- Orange, a major operator in Europe, launched their Navigation Services


platform with SiRFstarIII based SPV M650, their first GSM/Edge phone


with integrated GPS, as well as SiRFstarIII based GPS-Bluetooth


accessories.


-- Telephonica O2, a major operator in UK and many other European


countries, launched SiRFstarIII based O2 Xda Orbit, their first


GSM/Edge phone with integrated GPS and navigation software.


-- Four of our customers passed basic 3GPP testing for their GPS-enabled


handsets either in-house or with a major operator. 3GPP or the 3rd


Generation Partnership Project is a collaboration agreement to produce


and maintain globally applicable Technical Specifications and Technical


Reports for a 3rd Generation Mobile System and for GSM. Passing 3GPP


for location is a key requirement for operator deployment of handsets


with GPS.


-- BenQ Mobile, an industry leader in wireless communication devices,


launched their SiRFstarIII based BenQ-Siemens P51 smart phone in China.


-- Pantech, one of Korea's leading mobile phone manufacturers, launched an


extremely small form factor, SiRFstarIII based AGPS/CDMA Phone for SK


Telecom.


-- Gigabyte, a well known IT brand, demonstrated g-Smart i300, a triband


GSM smart phone at the 3GSM Asia conference in October.


-- Asus, a leading provider of 3C (computers, communications and consumer


electronics) total solutions, launched P535, a triband smart phone with


integrated SiRFstarIII GPS.


-- E-TEN, a leading manufacturer of smart handheld devices, launched the


glofiish M700, a SiRF Star III based sliding keyboard Pocket PC Phone


that supports GSM, GPRS and EDGE for voice and data connectivity as


well as Wi-Fi connectivity.

USE OF NON-GAAP FINANCIAL INFORMATION:


To supplement the company's condensed consolidated financial statements presented on a GAAP basis, SiRF uses non-GAAP additional measures of operating results, net income and net income per share adjusted to exclude certain expenses it believes appropriate to enhance an overall understanding of SiRF's past financial performance and also its prospects for the future. We present such non-GAAP financial measures in reporting our financial results to provide investors with an additional tool to evaluate our operating results. Because these non-GAAP measures are not calculated in accordance with GAAP, it may not necessarily be comparable to similarly titled measures employed by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP measures, and should be read only in conjunction with our condensed consolidated financial statements prepared in accordance with GAAP.


SiRF management uses each of the above non-GAAP financial measures internally to understand, manage and evaluate our business. SiRF believes it is useful for itself and investors to review, as applicable, both GAAP information, which includes amortization of acquisition-related intangibles, employee stock compensation expense, acquired in-process research and development, expenses related to acquisition-related contingent payments, benefits related to acquisition-related tax benefits, certain one-time tax benefits from research and development tax credits and the reversal of a litigation settlement, and the non-GAAP measures, which exclude this information, in order to assess the performance of our continuing business and for planning and forecasting in future periods. Each of these non-GAAP measures is intended to provide investors with an understanding of our operational results and trends that enables them to analyze our base financial and operating performance and facilitate period-to-period comparisons and analysis of operational trends. SiRF believes each of these non-GAAP financial measures is useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making.


Our non-GAAP financial measures reflect adjustments based on the following items:


-- Amortization of acquisition-related intangible assets: SiRF has


excluded the effects of amortization of acquisition-related intangible


assets from our non-GAAP net income because these costs are associated


with the acquisition of entities that would not have otherwise been


incurred. This non-GAAP adjustment is intended to reflect acquisition-


related expense incurred that is not directly associated with our


continuing operations.


-- Stock compensation expense: Our operating expenses include stock


compensation expense related to the adoption SFAS No. 123R, which


requires us to recognize a non-cash expense related to the fair value


of all our employee stock-based compensation awards. In periods prior


to the adoption of SFAS No. 123R, when employee stock-based


compensation awards had an exercise price equal to or above the market


value of the underlying common stock on the date of grant, no stock


compensation expense was recognized in our statement of operations. In


periods prior to the adoption of SFAS No. 123R, we recorded stock


compensation expense associated with equity awards issued in


conjunction with acquisitions and pre-IPO options granted at less than


deemed fair market value. We believe it is useful to highlight the


effect of this stock compensation expense because historical practices


under previously applicable accounting principles were not on the same


basis. However, stock-based compensation is a key incentive offered to


our employees, and we believe it contributed to the revenue earned


during the period and will contribute to our future revenue generation.


Stock compensation expenses will recur in future periods.


-- Acquired in-process research and development: SiRF incurred one-time


charges in connection with the acquisition of TrueSpan during the first


quarter of fiscal 2006 and the acquisition of the Motorola's GPS chip


set product family and Impulsesoft during fiscal 2005 that otherwise


would not have been incurred and therefore we have excluded the effects


of these charges from our non-GAAP net income. In-process research and


development consists of technology projects which, as of acquisition


date, had not yet reached technological feasibility and there are no


future alternative uses that exist. We believe it is useful for


investors to understand the effect of this expense on our statement of


operations. This non-GAAP adjustment is intended to reflect


acquisition-related expense incurred that is not directly associated


with our continuing operations.


-- Acquisition-related tax benefits: In fiscal 2005, SiRF excluded a one-


time benefit associated with acquisition-related tax credits related to


its assessment of its ability to utilize certain net operating losses


that were acquired in connection with the 2003 Enuvis acquisition


pursuant to Section 382 of the Internal Revenue Code of 1986, as


amended. Had this acquisition not occurred, these benefits would not


have been recorded. We believe it is useful for investors to understand


the effect of this tax benefit on our statement of operations.


-- Expenses related to acquisition-related contingent payments: SiRF has


excluded the effects of compensation expense recorded in relation to


acquisition-related contingent payments from our non-GAAP net income


because these costs are associated with the acquisition of companies


that would not have otherwise been incurred. These non-GAAP


adjustments are intended to reflect additional acquisition-related


payments and are not directly associated with our continuing


operations. We believe these adjustments are useful to investors as


this expense is not part of our continuing operations.


-- Research and development tax credit: In the fourth quarter of fiscal


2006, SiRF excluded the portion of the one-time tax benefit from


research and development tax credits related to the first nine months


of the fiscal year, which was recognized during the fourth quarter as a


result of the timing of the reinstatement of the federal research and


development tax credit. However, the tax benefit from research and


development tax credits for the 2006 fiscal year have been included in


SiRF's non-GAAP operating results for fiscal 2006. In fiscal 2005, SiRF


excluded from our non-GAAP operating results certain income tax


benefits related to research and development tax credits resulting from


a research and development tax credit study for previously unrecognized


tax benefits for the years 1997 - 2004. These non-GAAP adjustments are


intended to reflect one-time additional benefits that are not directly


associated with our current operations. We believe it is useful for


investors to understand the effect of these tax benefits on our


statement of operations.


-- Reversal of litigation settlement obligation: In fiscal 2005, SiRF


recorded a one-time reversal of short- and long-term settlement


liabilities in connection with SiRF's satisfaction in full of its


settlement obligations under a settlement agreement regarding certain


patent rights that was executed in the year 2000. We believe it is


useful for investors to understand the effect of this reversal on our


statement of operations as we believe the reversal of such items is


non-recurring by nature.


FORWARD-LOOKING STATEMENTS:


Except for the historical information contained herein, the matters set forth in this press release, including but not limited to, statements regarding the wireless market growth, deployment or IOT of handsets with build-in GPS or GPS accessories, the benefits to our management and investors of using non-GAAP measurements, the purpose of using non-GAAP measurement, the recurrence of these expenses in the future and the contribution of stock-based compensation to our revenue are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as "to," "being," "possible," "may," "address," "designed to," "provide," "anticipate," "believe," "expect," "plan," "will," and similar expressions are intended to identify forward-looking statements.
