Fourth Quarter and FY2013 Results

Subscription revenue for the year and quarter ended December 31, 2013 grew 3% and 5%, respectively, over the same periods in 2012. The Company’s annual operating initiatives are designed to drive subscription revenue growth.

Total revenue for the years ended December 31, 2013 and 2012 was flat at $22.0 million. Fourth quarter 2013 revenue was $5.6 million, up by 2% compared to the same period last year.

ACV increased by 4% to $19.6 million in Q4 2013 from $18.8 million one year ago. Growth in ACV indicates that new client acquisitions, contract expansions and improving client retention rates have more than offset the impact of client attrition. ACV represents the aggregate annual value of our subscription contracts and is a leading indicator of future revenue growth. For more information about ACV, see “Key Metric Definitions” below.

ACVC increased 13% to $5,387 in Q4 2013 compared to $4,775 in Q4 2012. ACVC for new clients increased 53% to $13,599 from $8,891 in Q4 2012. Growth in ACVC demonstrates that an increasing number of clients have a strategic interest in the public sector at a regional or national level. Companies within this target market typically have higher ACVC and renew at higher rates, which are key attributes of a profitable long-term client.

As of December 31, 2013, Onvia has 3,650 clients, down 8% from 3,950 clients during the same period one year ago. Our strategy is to continue to improve profitability by acquiring and managing fewer strategic clients at a higher ACVC. We believe that ACV is a better measure of quarterly sales activity than number of clients.

Gross margin was 84% in the fourth quarter of 2013 consistent with the fourth quarter of 2012. For the year, gross margin was 83% compared to from 84% in the full year of 2012. We regularly evaluate potential investments in new or enhanced content that could increase the value of our solution to our clients.

2013 operating expenses increased 2% to $18.8 million compared to $18.5 million in 2012. Depreciation and amortization increased approximately $210,000 in 2013 due, in part, to the launch of Onvia 6 in March 2013 and Vendor Center in December 2013.

In the fourth quarter of 2013, sales and marketing costs were up 8% compared to the third quarter of 2013, due to the strong performance by the SMB acquisition sales team. We expense 100% of variable sales cost upon sale, but recognize revenue on no more than 8% of a new sale each month. In the month of the new sale, variable sales costs exceed the incremental revenue generated; therefore growth in new client acquisition can have a noticeable, negative impact on short term Adjusted EBITDA and net income.

Adjusted EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization, and non-cash stock-based compensation) for the year ended December 31, 2013 was $2.8 million down 8% from $3.0 million in 2012. Fourth quarter Adjusted EBITDA increased to $605,000, compared to Adjusted EBITDA of $590,000 in the same year-ago period. Net loss was $244,000 or $(0.03) cents per diluted share, compared to net income of $1.3 million or $0.15 cents per diluted share in the fourth quarter of 2012. Net income in the fourth quarter and full year of 2012 included the recognition of a deferred tax benefit of $1.6 million.

At December 31, 2013, cash, cash equivalents and investments decreased by $4.8 million to $7.5 million compared to the end of 2012 primarily due to the Company’s repurchase of 1.2 million shares of its outstanding common stock from a third party at $3.50 per share on April 4, 2013. We believe that the remaining cash balance is adequate to fund operations until Adjusted EBITDA and free cash flow accelerate.

Onvia had approximately $24.9 million in deferred tax assets as of December 31, 2013. The Company has recorded a valuation allowance for the majority of its net deferred tax assets because it has not consistently generated taxable net income and has generated net losses over the last five quarters. However, the leading indicators of revenue growth continue to improve, which should deliver higher revenue and net income in the future. Onvia evaluated the likelihood that these tax benefits may be realized, and believes that the net deferred tax assets balance as of December 31, 2013 is reflective of the amount we expect to realize in the foreseeable future. Onvia may reverse all or a portion of its valuation allowance in the future if it is determined that realization of these benefits is more likely than not.

2013 Initiatives

Onvia’s first 2013 initiative was to successfully expand SMB Acquisition, now called Business Development. For the year, Business Development bookings increased 28% over the 2012, and fourth quarter bookings grew 39% over last year, compared to 35% growth reported last quarter. New client ACVC increased 53% to $13,599 from $8,891 in Q4 2012. This initiative fell short of the annual goal, but results improved significantly over the last two quarters as a result of the changes we made to our go to market strategy.

The second initiative is to maximize contract expansions within the existing client base and ensure that clients receive the optimal Onvia solution for their public sector objectives. The success of this initiative is measured by the growth in contract value of existing contracts in 2013 when compared with 2012. In Q4 2013, the contract value growth increased by 20% compared to the same year ago period. Effective January 2014, we created a new role on the Client Success team responsible for contract expansion which should improve the penetration rate within the existing client base.

The third initiative is to strengthen the value of the database and continue to add solutions to help clients win more government business. In the fourth quarter, we launched Vendor Center which provides strategic intelligence on companies that do business with state and local governments. Clients will be able to identify, track and benchmark competitors and potential partners to inform strategic decision making. Vendor Center represents an important step in our strategy to move from lead distribution into public sector market intelligence and analysis.

2013 in Review

“In the first half of 2013 we fell short of our goal to accelerate subscription revenue and Adjusted EBITDA,” stated Hank Riner, Onvia’s Chief Executive Officer. “In response, we made a number of changes to our go-to market strategy, which we began to implement in the fourth quarter of 2013. First, we refined our target market to include only those companies that have the strongest need for public sector strategic intelligence. We now focus on regional or national companies that do business in the three largest market sectors, Infrastructure, Information Technology and outsourced Business Services for the state and local government markets.”

“Second, we made organizational changes to support the new go to market strategy,” continued Mr. Riner. “We aligned our Business Development, Client Success and Marketing organizations around these three key market sectors. In the Client Success organization, we separated the responsibility for client service from contract growth into separate roles to better improve on the clients’ business objectives. Finally, we created a new team responsible for onboarding and training new clients expected to improve the 1^st year experience for new clients and ultimately first year retention rates. These adjustments to our go to market strategy are intended to accelerate new client acquisitions, improve client retention and expand adoption of additional solutions throughout the client base.”

“Finally, we combined the Enterprise and SMB sales forces into one sales organization,” Mr. Riner concluded. “Since our enterprise strategy is to sell to the division or subsidiary of a large company, this market has similar characteristics and requirements as the high end SMB market. The combined sales team is now focused on selling the same solution to the same type of customer using the same selling process. We have simplified our sales organization so we can respond to market changes faster.”

2014 Initiatives

Subscription revenue began to accelerate in the fourth quarter of 2013, a few quarters later than originally anticipated. In 2014, the Company is executing four initiatives intended to build on fourth quarter results and further accelerate growth in subscription revenue and Adjusted EBTIDA.

The first 2014 initiative is to accelerate the acquisition of new clients within the defined verticals of the new target market. We will measure the success of this initiative by the overall growth in new client bookings and new client ACVC year over year.

The second initiative is to improve first year client retention and renew our tenured, long term clients within our target market. The Company will measure the success of this initiative in the year over year growth in revenue retention which will be reported beginning in the first quarter of 2014. Revenue retention should provide shareholders insight into the Company’s subscription retention rate and ability to generate future subscription revenue.

The third initiative is to maximize growth within the existing client base. The Company will measure the success of this initiative in the year over year growth in wallet retention which will be reported beginning in the first quarter of 2014. Wallet retention should provide shareholders insight into the Company’s ability to expand existing subscription contracts.

The fourth and final 2014 initiative is to continue to drive enhancements to the existing Onvia platform and to provide innovative new solutions that make Onvia a strategic business partner with its clients. We will measure this initiative based upon the effectiveness of strategic product releases and their impact on new client ACVC and wallet retention.

Use of Non-GAAP Financial Information

Adjusted EBITDA is not a financial measure calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”) and should not be considered as an alternative to net income, operating income or any other financial measures so calculated and presented, nor as an alternative to cash flow from operating activities as a measure of the company’s liquidity. Onvia defines Adjusted EBITDA as net income / (loss) before interest expense and other non-cash financing costs; taxes; depreciation; amortization; and non-cash stock-based compensation. Other companies (including Onvia’s competitors) may define Adjusted EBITDA differently. Onvia presents Adjusted EBITDA because it believes Adjusted EBITDA to be an important supplemental measure of performance that is commonly used by securities analysts, investors and other interested parties in the evaluation of companies in similar industries and size. Management also uses this information internally for forecasting and budgeting. It may not be indicative of the historical operating results of Onvia nor is it intended to be predictive of potential future results. Investors should not consider Adjusted EBITDA in isolation or as a substitute for analysis of results as reported under GAAP. See “Reconciliation of GAAP Net (Loss) / Income to Adjusted EBITDA” below for further information on this non-GAAP measure and for a reconciliation of GAAP Net (Loss) / Income to Adjusted EBITDA for the periods indicated.

Key Metric Definitions

Onvia also supplements its financial statements in this release and in its annual report on Form 10-K and quarterly reports on Form 10-Q with a calculation of Annual Contract Value. Onvia will begin reporting revenue retention and wallet retention starting in the first quarter of 2014. These metrics are not financial measures calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”) and should not be considered as an alternative to revenue or any other financial measures so calculated. Management uses this information as a basis for planning and forecasting core business activity for future periods and believes it is useful in understanding the results of its operations.

Annual Contract Value (ACV) represents the annualized aggregate revenue value of all subscription contracts as of the end of the quarter. ACV is driven by Annual Contract Value per Client (ACVC) and the number of clients. Most of Onvia’s revenues are generated from subscription contracts, which are typically prepaid and have a minimum term of one year, with revenues recognized ratably over the term of the subscription. Onvia also receives revenue from multi-year content distribution partnerships, stand-alone management reports, document download services, and list rental services, which are not included in the calculation of ACV.
