SPARK NETWORKS REPORTS FIRST QUARTER 2006 FINANCIAL RESULTS

BEVERLY HILLS, Calif., April 27, 2006 — Spark Networks plc (AMEX: LOV), a leading provider of online personals services, today reported first quarter 2006 financial results.

Financial Results

Reported revenue for the first quarter of 2006 was $16.8 million, an increase of 2% compared to $16.5 million over the same period in 2005. The increase is largely a result of the Company’s acquisition of MingleMatch in the second quarter of 2005. The first quarter is typically a strong quarter for the Company, and the first quarter of 2005 was particularly strong given the carry-over effect of significant marketing expenditures for AmericanSingles^® in the last half of 2004. Since the last half of 2004, the Company has reduced spending for AmericanSingles in order to lower overall customer acquisition costs for AmericanSingles, thus improving its contribution margin.

Total operating expenses for the first quarter of 2006 were $10.2 million, an increase of 10% compared to $9.3 million in the same period in 2005. The increase in operating expenses was primarily attributable to share-based compensation expense of approximately $1.4 million as a result of the Company’s adoption of the Statement of Financial Accounting Standards No. 123 (R) (“SFAS 123 (R)”) in the third quarter of 2005. Periods prior to the third quarter of 2005 do not contain any expense for share options in accordance with SFAS 123(R). Even including operating expenses related to its MingleMatch subsidiary, which the Company acquired in the second quarter of 2005, total operating expenses for the first quarter of 2006 would actually have been lower than those in the first quarter of 2005 absent the SFAS 123 (R) share-based compensation expense.

The Company reported net income of $710,000, or $0.02 per share, for the first quarter of 2006, compared to net income of $2.0 million, or $0.08 per share, for the same period in 2005. Due to the Company’s implementation of SFAS 123 (R), the net income for the quarter ended March 31, 2006 includes compensation expense related to share options of $1.4 million. Excluding share-based compensation, the Company would have reported a profit of $2.1 million, or $0.07 per share¹, for the quarter.

EBITDAS² (EBITDA adjusted to remove share-based compensation expense) for the first quarter of 2006 was $3.4 million, and increase of 10% compared to EBITDAS of $3.1 million during the same period in 2005. See the attached Consolidated Statement of Operations for a reconciliation of EBITDA and EBITDAS to net income.

Also during the first quarter, the Company redesigned and rebranded its Christian community as Relationships.com (www.relationships.com). Already the most visited online community for Christian singles³, the new Relationships.com brand better represents today’s Christian singles and provides a unique online community created for Christian singles looking to make new friends or find life-long partners who share similar values, traditions and beliefs.

Balance Sheet, Cash, Debt

As of March 31, 2006, the Company had a cash and marketable securities position of $15.8 million, compared to $17.3 million at December 31, 2005. As of March 31, 2006, the Company had remaining payments in respect of the purchase of MingleMatch of $4.0 million, which are due in May 2006, and has accumulated over $50.0 million of NOLs. Cash flow from operations during the first quarter was $4.3 million driven by an increase in multi-month subscription sales, where cash is received up front and service is provided over the life of the subscription.

Segment Reporting⁴

The Company reported first quarter 2006 revenue for its JDate segment of $7.0 million, an increase of 8% compared to $6.5 million in the same period in 2005.

The Company reported first quarter 2006 revenue for its AmericanSingles segment of $6.3 million, a decrease of 22% compared to $8.1 million in the same period in 2005. The decrease in revenues for AmericanSingles is largely attributable to a 34% decrease in the AmericanSingles marketing spend in the last half of 2005 compared to the last half of 2004.

The Company reported first quarter 2006 revenue for its Other Businesses segment of $3.5 million, an increase of 75% compared to $2.0 million in the same period in 2005. The increase in revenue was primarily driven by the acquisition of MingleMatch in the second quarter of 2005, and strong growth from the websites associated with the acquisition.

Business Metrics

Average paying subscribers for the Company’s JDate segment were 79,500 during the first quarter of 2006, an increase of 13% compared to 70,400 from the same period in 2005.

Average paying subscribers for the Company’s AmericanSingles segment were 98,800 during the first quarter of 2006, a decrease of 19% compared to 121,600 from the same period in 2005.

Average paying subscribers for the Company’s Other Businesses segment were 66,000 during the first quarter of 2006, an increase of 116% compared to 30,600 from the same period in 2005.

Average paying subscribers for the Company, as a whole, in the first quarter of 2006 were approximately 244,300, an increase of 10% compared to 222,600 from the same period in 2005.

Direct subscriber acquisition cost⁵ (SAC) for the Company’s JDate segment in the first quarter of 2006 was $13.20, an increase of 47% compared to $9.01 from the same period in 2005. When comparing JDate SAC in the first quarter to that in the same period in 2005, it is important to consider that SAC metrics for JDate now reflect a wider mix of offline initiatives focused on continuing to build the JDate brand.

SAC for the Company’s AmericanSingles segment in the first quarter of 2006 was $35.19, an increase of 37% compared to $25.61 in the same period in 2005. The increase in SAC for AmericanSingles is the result of the previously discussed significant cuts in marketing spending in the first quarter of 2005 compared to the last half of 2004. The carry-over effect in the first quarter of 2005 of increased subscriptions from previous marketing, combined with reduced marketing expense, made for an atypically low SAC in the first quarter of 2005. Since the first quarter of 2005, the Company has slightly increased marketing spending for AmericanSingles.

SAC for the Company’s Other Businesses segment in the first quarter of 2006 was $24.68, a decrease of 47% compared to $46.97 from the same period in 2005. The significant decrease in SAC for the Other Businesses segment is due to the addition of the 20+ affinity-focused websites that were acquired with MingleMatch and the lower customer acquisition cost the Company encounters with regard to JDate and its other affinity-focused websites.

SAC for the Company as a whole in the first quarter of 2006 was $26.11, an increase of 10% compared to $23.84 from the same period last year.

About Spark Networks plc:

¹ Share-based compensation is a non-cash charge recorded in the Company’s income statements. The Company believes that the non-GAAP financial measures that exclude share-based compensation from net income (loss) provide useful information to management and investors regarding how the expenses associated with the application of SFAS 123 (R) are reflected on the statements of operations and facilitate comparisons to the Company’s historical operating results. The Company’s management uses this information internally for reviewing the financial results, forecasting and budgeting.

² “EBITDAS” is defined as earnings before interest, taxes, depreciation, amortization and share-based compensation. EBITDAS should not be construed as a substitute for net income (loss) or net cash provided by (used in) operating activities (all as determined in accordance with GAAP) for the purpose of analyzing our operating performance, financial position and cash flows, as EBITDAS is not defined by GAAP. However, the Company regards EBITDAS as a complement to net income and other GAAP financial performance measures, including an indirect measure of operating cash flow. As such, management believes that the investment community finds it to be a useful tool to perform meaningful comparisons of past, present and future operating results and as a means to evaluate the results of core on-going operations.

³ An analysis of comScore Media Metrix data for the three months ended March 31, 2006, revealed that Relationships.com (formerlyChristianMingle.com) attracted more unique visitors than any other Christian online personals service in the United States, making it the most-visited Christian online personals service in the U.S.

⁴ In accordance with Financial Accounting Standard No. 131, the Company’s financial reporting includes detailed data on three separate operating segments. The JDate segment consists of the Company’s JDate.com website and its co-branded websites. The AmericanSingles segment consists of the Company’s AmericanSingles.com website and its co-branded and private label websites. The Other Businesses segment consists of all of the Company’s other websites and businesses and gives effect to the MingleMatch acquisition on May 19, 2005.

⁵ Direct subscriber acquisition cost is defined as total direct marketing costs divided by the number of new paying subscribers during the period. This represents the average cost of acquiring a new paying subscriber during the period.

We define our key business metrics as follows:

•		Average paying subscribers: Paying subscribers are defined as individuals who have paid a monthly fee for access to communication and website features beyond those provided to our members. Average paying subscribers for each month are calculated as the sum of the paying subscribers at the beginning and end of the month, divided by two. Average paying subscribers for periods longer than one month are calculated as the sum of the average paying subscribers for each month, divided by the number of months in such period.
•		Average monthly net revenue per paying subscriber: Average monthly net revenue per paying subscriber represents the total net subscriber revenue for the

		period divided by the number of average paying subscribers for the period, divided by the number of months in the period.
•		Direct subscriber acquisition cost: Direct subscriber acquisition cost is defined as total direct marketing costs divided by the number of new paying subscribers during the period. This represents the average cost of acquiring a new paying subscriber during the period.
•		Monthly subscriber churn: Monthly subscriber churn represents the ratio, expressed as a percentage, of (i) the number of paying subscriber cancellations during the period divided by the number of average paying subscribers during the period and (ii) the number of months in the period.
