Occam Networks Reports Fourth Quarter and Fiscal Year End Results.

Closes Year by Surpassing One Millionth Port Milestone

SANTA BARBARA, Calif. -- Occam Networks, Inc. (NASDAQ:OCNW), a leading supplier of innovative Ethernet and IP-based loop carrier equipment to telecommunications companies, today announced its financial results for the quarter and year ended December 31, 2006.

Revenues totaled $20.1 million for the fourth quarter, which ended December 31, 2006, a tenth straight quarter of increased revenues. Fourth quarter 2006 revenues represented an increase of 56% over the fourth quarter of 2005 and 11% sequentially over the third quarter of 2006. Annual revenue for 2006 was $68.6 million, representing a 75% increase over annual revenue for 2005. Net income for the fourth quarter of 2006, calculated in accordance with generally accepted accounting principles ("GAAP"), was $0.9 million or $0.04 per diluted share compared with net income of $0.4 million or $0.03 per diluted share for the fourth quarter of 2005 and net income of $0.2 million or $0.01 per diluted share for the third quarter of 2006. Annual net losses for 2006 and 2005 were $1.9 million and $9.3 million, respectively. The results for 2006 and 2005 included beneficial conversion feature charges related to the issuance of preferred stock and warrants. These non-cash charges were calculated in accordance with GAAP and are expected to be non-recurring. The results for 2006 and 2005 also include non-cash, employee stock-based compensation expenses. Pro forma net income before stock-based compensation was $1.5 million for the fourth quarter of 2006, compared to pro forma net income of $0.6 million for the fourth quarter of 2005 and $0.7 million for the third quarter of 2006. Pro forma net income before beneficial conversion feature charges and stock-based compensation for 2006 was $3.4 million. Pro forma net loss before beneficial conversion feature charges and stock-based compensation for 2005 was $6.8 million. A reconciliation of Occam's GAAP and pro forma financial results, together with a statement of how management uses the non-GAAP financial information, is set forth below.

The company also finished the fiscal year by surpassing one million ports shipped. The company believes its fiscal year end results reflect increasing interest among telecommunications service providers in upgrading their networks to offer IPTV, Triple Play and other new, innovative services.

"Occam's focus on offering IP- and Ethernet-based technologies allowing telco service providers to bring exciting services to residential and business subscribers bore outstanding returns for Occam in 2006," said Bob Howard-Anderson, Occam's president and chief executive officer. "Achieving our millionth port shipped was among the year's highlights."

In addition to surpassing the millionth port shipped mark, Occam's important 2006 milestones included:

* Occam surpassed the 200 customer mark, demonstrating the continued strong interest among telecommunications carriers in Occam's IP- and Ethernet-based approach to offering new, innovative services.

* Occam completed a relisting onto NASDAQ from the OTC bulletin board, and a secondary equity offering that raised $48.7 million, net of issuance costs.

* Occam added Session Initiation Protocol (SIP) to its OccamOS, enabling telcos to choose from SIP, MGCP, GR303 or TR08 for voice service control.

* Technology Marketing Corporation's TMC Labs recognized Occam Networks' BLC 6314 10GigE Transport and Optical Line Termination (OLT) Blade with a 2006 Innovation Award, citing these products as "groundbreaking."

Use of Non-GAAP Financial Information

To supplement our consolidated financial statements presented on a GAAP basis, Occam uses non-GAAP measures of operating results, net income (loss) and income per (loss) share, which are adjusted to exclude certain costs, expenses, gains and losses we believe appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period GAAP results are made with the intent of providing both management and investors a more complete understanding of Occam's underlying operational results and trends and our marketplace performance. For example, the non-GAAP results are an indication of our baseline performance before gains, losses or other charges that are considered by management to be outside of our core operating results and are excluded by management for purposes of internal budgets and making operational decisions. In addition, these adjusted non-GAAP results are among the primary indicators management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income (loss) or net income (loss) per share prepared in accordance with accounting principles generally accepted in the United States.
