SANTA ANA, Calif. — May 26, 2011 — Iteris, Inc. (NYSE Amex: ITI), a leader in the traffic management market that focuses on the application and development of advanced technologies, reported financial results for its fourth fiscal quarter ended March 31, 2011.

·                  Revenues up 4% in the quarter to $15.7 million; full year up 2% to $59.4 million

·                  Roadway and Vehicle Sensors net sales up 11% and 19%, respectively for fiscal 2011

Management Commentary

“Our Roadway segment continued to drive growth in revenues for both the fourth quarter and fiscal year, and our Vehicle Sensors segment enjoyed strong year-over-year growth,” said Abbas Mohaddes, president and CEO of Iteris. “Our results also reflect actions we have taken to expand our market share through investments in both sales and marketing and R&D. Our consolidated growth objectives were hampered by continued soft spending in the Transportation Systems customer base. We are seeing signs of recovery in this space as a result of increased capital spending by many regional agencies, as well as increases in requests for proposal activities.”

“During the quarter, we successfully integrated our acquisition of Meridian Environmental Technology (MET),” continued Mohaddes. “This acquisition is aligned with our accelerated growth strategy to target synergistic companies that enhance our intellectual property. The addition of MET strengthens our offerings in key niche markets which include traveler information and decision support systems.”

“We expect to continue to make investments in sales and marketing and R&D,” concluded Mohaddes. “We believe these prudent investments, combined with synergistic acquisitions, and anticipated increases in the funding and growth of the traffic management market are multiple positive drivers that support our anticipated growth as we begin fiscal 2012.”

Fiscal Q4 2011 Financial Results

Net sales and contract revenues for the fourth quarter totaled $15.7 million compared to $15.0 million in the same year-ago quarter. The increase was primarily due to the acquisition of MET in January 2011 which contributed an additional $1.5 million in contract revenues during the quarter, offset by a 10% decline in Transportation Systems contract revenues.

Gross margins in the fourth quarter were 43.9% or $6.9 million, an improvement from 43.2% or $6.5 million in the same year-ago quarter. Operating expenses increased 17.4% to $6.2 million, mainly related to an increase in sales and marketing expenditures and the inclusion of MET’s operating expenses.

Non-GAAP net income was $555,000 or $0.02 per diluted share in the fourth quarter of fiscal 2011, as compared to $911,000 or $0.03 per diluted share in the same year-ago quarter (see “Use of Non-GAAP Financial Information,” below). GAAP net income was $479,000 or $0.01 per diluted share in the fourth quarter of fiscal 2011 versus $807,000 or $0.02 per diluted share in the same year-ago quarter.

Fiscal 2011 Financial Results

For fiscal year 2011, net sales and contract revenues increased 2.4% over the prior year to $59.4 million.

Gross margins were 43.6% or $25.9 million, increasing from 41.6% or $24.2 million in fiscal year 2010 mainly due to the mix of product sales versus consulting revenues. Operating expenses increased 47.1% to $30.7 million, primarily attributable to an $8.0 million non-cash charge for goodwill impairment in the third quarter of 2011.

Non-GAAP net income was $2.6 million or $0.07 per diluted share, virtually unchanged from the prior year. GAAP net loss was $5.2 million or $(0.15) per diluted share in fiscal 2011 versus GAAP net income of $2.2 million or $0.06 per diluted share in fiscal 2010, with the loss in fiscal 2011 again primarily attributable to the non-cash charge for goodwill impairment in the third quarter.

Cash at the end of fiscal 2011 was $11.8 million, an increase of $1.4 million from $10.4 million at the end of the prior fiscal year. Additionally, the company reduced its outstanding term debt by $2.3 million, from $5.3 million as of March 31, 2010, to $3.0 million at March 31, 2011.

Fiscal Q4 2011 Operational Highlights

·                  The Georgia Department of Transportation’s 511 real-time traveler information system set new motorist assistance records during a snow and ice storm. The record 95,000 calls over a four-day period demonstrated how MET’s strength and experience in 511 systems complements Iteris’ offerings. Iteris and MET are working with several other states in effort to expand their 511 offerings.

·                  Iteris was selected to power Audiovox’s new “Distracted Driver” Safety System, representing Iteris’ first entry into the consumer auto aftermarket. The system is expected to be available by the end of Iteris’ fiscal year 2012.

·                  Signed $3.1 million in Transportation Systems consulting contracts during the quarter resulting in contract backlog of $25.5 million as of March 31, 2011 providing a strong base to build upon as the company enters their new fiscal year.

Use of Non-GAAP Financial Information

Iteris reports net income (loss) and diluted earnings (loss) per share in accordance with accounting principles generally accepted in the United States (“GAAP”) and supplementally on a non-GAAP basis.  The company’s presentation of non-GAAP net income and non-GAAP diluted earnings per share excludes the impact of charges related to the impairment of goodwill, stock-based compensation, and the amortization of certain intangible assets. A reconciliation of these GAAP and non-GAAP financial measures for all periods presented is found in the attached “Unaudited Reconciliation of Non-GAAP Adjustments.”

Iteris believes that the presentation of non-GAAP net income and non-GAAP diluted earnings per share provides important supplemental information to management and investors regarding financial and business trends relating to our financial condition and results of operations. Iteris also believes that the use of these non-GAAP financial measures provides consistency and comparability among and between results from prior periods or forecasts and future prospects, and also facilitates comparisons with other companies in our industry, many of which use similar non-GAAP financial measures to supplement their GAAP results. The company’s management generally uses non-GAAP net income and non-GAAP earnings per share to evaluate the operating performance of Iteris, because management believes that the inclusion or exclusion of the items described above provides insight into its core operating results, its ability to generate cash and underlying business trends affecting the company’s performance.  In addition, Iteris has excluded stock-based compensation expenses since these expenses rely on valuations based on future events such as the market price of our common stock, which are difficult to predict and are affected by market factors that are largely not within the control of management. Iteris has chosen to provide this non-GAAP information to investors to enable them to perform additional analyses of past, present, and future operating performance and as a supplemental means to evaluate our ongoing core operations. The non-GAAP financial information presented herein should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.
