FOR IMMEDIATE RELEASE

HEARTLAND PAYMENT SYSTEMS REPORTS SECOND QUARTER RESULTS

Princeton, NJ – August 4, 2010 – Heartland Payment Systems, Inc. (NYSE: HPY), one of the nation’s largest payment processors, today announced second quarter GAAP net income of $6.1 million or $0.16 per diluted share. Results for the quarter are after $4.9 million (pre-tax), or $0.07 per diluted share, of various expenses and accruals, all of which are attributable to the processing system intrusion. Excluding these expenses and accruals, Adjusted Net Income and Diluted Earnings per Share were $9.1 million and $0.23, respectively, for the second quarter. Adjusted Net Income and Diluted Earnings per Share are non-GAAP measures that exclude certain items detailed later in this press release under the heading “Use of Non-GAAP Financial Measures.”

Highlights for the Second Quarter include:

Robert Carr, Chairman and CEO, said, “Both transaction processing volume and Network Services transactions processed reached quarterly records in the second quarter, while same store sales turned positive and contributed to our growth for the first time in over two years. As a result, the rate of net revenue growth in the quarter improved relative to the first quarter. By continuing to carefully manage

expenses, we were able to achieve a 13.2 percent operating margin in the quarter, indicative of the progress we are achieving better leveraging our business model, in addition to the seasonal rebound in our margins. It is particularly rewarding to have reached these levels of activity during a period of continued muted economic activity and at a time when we have been heavily investing in our organization to launch a number of new growth initiatives. Over the past three months our relationship manager count has increased by 24 percent as we fill open positions and implement our focused vertical industry marketing strategy. This focus has already received recognition from the restaurant, lodging and healthcare industries currently being served, including a recent endorsement from the Texas Hotel and Lodging Association and preferred payments partner status with the California Medical Association. In addition, this quarter our new end-to-end encryption technology, E3™, hit the market, with over 3,000 of our industry-leading terminals having already been installed by more than 2,500 merchants. As the economy recovers and our new growth strategies gain traction, we expect that our unwavering commitment to strengthen the Heartland franchise through continual investment in our organization will position us to achieve our long-term growth objectives and create value for our shareholders.”

Net revenues in the second quarter of 2010 were up 8.1% from the second quarter of 2009 to $115.1 million, primarily driven by an 8% increase in SME Card processing volume, which was a record $16.3 billion in the quarter. Net revenue also benefitted from a quarterly record 800 million Network Services transactions, which were up nearly 10% from 728 million transactions in the June quarter of last year. In the second quarter of 2010, operating income as a percentage of net revenues was 13.2%, reflecting improved leverage of the company’s business model through disciplined expense management. General and administrative expenses in the quarter were down both sequentially and on a year-over-year basis. In the second quarter, the Company incurred $4.9 million pre-tax, or $0.07 per diluted share in various expenses and accruals, all of which are attributable to the processing system intrusion. These various expenses and accruals are shown separately in the Company’s Statement of Operations. Interest expense for the second quarter of 2010 included approximately $0.5 million, or $0.01 per share, related to borrowings we incurred to fund the settlement with Visa in February 2010.

Mr. Carr continued, “Same store sales and transaction processing volumes are beginning to show improved performance. Our sales organization is growing very nicely, and our new products and marketing strategy are ramping up. Consequently, we intend to focus on accelerating growth in new margin installed and leveraging our investments in the second half of the year. Certainly, the economy, and especially consumer spending and its effect on small business activity, will play an important role in our near term opportunity. However, over the longer term, we believe Heartland is positioned to benefit from our pricing transparency, strong products, and now the industry’s leading security that merchants are demanding as they become increasingly educated and sensitized to their processing needs.”

SIX MONTH RESULTS:

For the first six months of 2010, GAAP net income was $20.4 million or $0.52 per diluted share compared to a net loss of $5.1 million or $0.14 per share for the first half of 2009. Net revenues for the first half of 2010 were $219.0 million, up 6.8% compared to the first half of 2009. Excluding various expenses, accruals, recoveries, and reserves, all of which are attributable to the processing system intrusion, adjusted net income and diluted earnings per share for the first half of fiscal 2010 were $10.8 million or $0.28 per diluted share, compared to $14.7 million, or $0.39 per share in the prior year six month period. Year-to-date 2010, stock compensation expense has reduced earnings by $2.8 million or $0.044 per diluted share compared to $1.1 million or $0.018 per diluted share a year ago.

USE OF NON-GAAP FINANCIAL MEASURES

To supplement its consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company provides additional measures of its operating results, net income and earnings per share, which exclude certain costs and expenses related to the processing system intrusion. The Company believes that these non-GAAP financial measures are appropriate to enhance understanding of its historical performance as well as prospects for its future performance.

Pursuant to Regulation G, a reconciliation of these non-GAAP financial measures with the comparable financial measures calculated in accordance with GAAP for the three and six months ended June 30, 2010 and 2009 follows:

Please see “Reconciliation of Non-GAAP Financial Measures and Regulation G Disclosure” below for additional detail.

FULL YEAR 2010 GUIDANCE:

The Company believes it has sufficient cash currently available to fund settlements associated with the processing system intrusion, so that it does not believe it will need to incur any additional borrowings beyond the current total debt outstanding of $115 million for this purpose. As such, the incremental interest expense attributable to any debt specifically incurred to satisfy the processing system intrusion liabilities can now be estimated. In addition, with the first half of the year completed, there is improved clarity as to likely same store sales and new margin installed performance for the year. For the full year 2010, we now expect net revenue (total revenues less interchange, dues, assessments and fees) to grow by 7 – 9%, to between $450 and $458 million. For the year, earnings per share are expected to be $0.95 - $1.00, excluding $0.11 per share of stock compensation and $0.03 per share of specifically identifiable processing system intrusion related interest expense. The Company’s guidance for 2010 does not include any estimates for potential losses, costs, expenses and accruals or recoveries arising from the previously announced processing system intrusion, exposure to various legal proceedings that are pending, or may arise, and related fees and expenses, and other potential liabilities, costs and expenses.

Reconciliation of Non-GAAP Financial Measures And Regulation G Disclosure

To supplement its consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company provides additional measures of its operating results, namely net income and earnings per share, which exclude certain costs and expenses and recoveries related to the criminal breach of its payment systems environment (the “Processing System Intrusion”). These measures meet the definition of a non-GAAP financial measure. The Company believes that application of these non-GAAP financial measures is appropriate to enhance understanding of its historical performance as well as prospects for its future performance.

Use and Economic Substance of the Non-GAAP Financial Measures— Management uses these non-GAAP measures to evaluate performance period over period, to analyze the underlying trends in the Company’s business, to assess its on-going operating performance relative to its competitors, and to establish operational goals and forecasts. Net costs and expenses related to the Processing System Intrusion are not indicative of the Company’s on-going operating performance and are therefore excluded by management in assessing the Company’s operating performance, as well as from the measures used for making operating decisions, although in making operating decisions management is mindful of its need to utilize cash to pay for the costs and expenses relating to the Processing System Intrusion.

The following is an explanation of the adjustments that management excluded as part of its non-GAAP measures for the three and six months ended June 30, 2010 and 2009:

Provision for Processing System Intrusion – On January 20, 2009, the Company publicly announced the discovery of the Processing System Intrusion. Since its announcement of the Processing System Intrusion on January 20, 2009 and through June 30, 2010, the Company has expensed a total of $144.2 million, before reducing those charges by $30.7 million of total insurance recoveries. The majority of the total charges, or approximately $114.7 million, related to consummated settlements of claims, settlements agreed upon, or settlements deemed likely to be agreed upon in the near term. Approximately $29.5 million of the total charges were for legal fees and costs we incurred for investigations, defending various claims and actions, remedial actions and crisis management services.

During the six months ended June 30, 2010, the Company recovered from its insurance providers approximately $26.8 million of the costs it incurred for the Processing System Intrusion and expensed approximately $11.2 million for accruals, legal fees and costs it incurred for defending various claims and actions, resulting in a net recovery of $15.5 million, or $0.24 per share. For the three months ended June 30, 2010, the Company expensed a total of $4.9 million, or about $0.07 per share, respectively, associated with the Processing System Intrusion.

Page 10

For the three and six months ended June 30, 2009, the Company expensed a total of $19.4 million and $32.0 million, respectively, or about $0.32 and $0.53 per share, respectively, for accruals, legal fees and costs it incurred for defending various claims and actions associated with the Processing System Intrusion.

At June 30, 2010, the Company carried a $42.3 million Reserve for Processing System Intrusion on its Consolidated Balance Sheet. The majority of this Reserve related to:

Notwithstanding its belief that it has strong defenses against the claim that is the subject of the settlement offer described in (ii) above, the Company decided to make the settlement offer and engage in settlement discussions in attempts to avoid the costs and uncertainty of litigation. The Company is prepared to vigorously defend itself against any unsettled claims relating to the Processing System Intrusion that have been asserted against it and its sponsor banks to date. The Company feels it has strong defenses to all the claims that have been asserted against it and its sponsor banks relating to the Processing System Intrusion.

Additional costs the Company expects to incur for legal fees and costs for defending various claims and actions associated with the Processing System Intrusion will be recognized as incurred. Such costs could be material and could adversely impact the Company’s results of operations, financial condition and cash flow.

Material Limitations Associated with the Use of Non-GAAP Financial Measures— Non-GAAP net income and non-GAAP earnings per share that exclude the impact of the Provision for Processing System Intrusion may have limitations as analytical tools, and these non-GAAP measures should not be considered in isolation from or as a replacement for GAAP financial measures, and should be considered only as supplemental to the Company’s GAAP financial measures. Some of the limitations associated with the use of these non-GAAP financial measures are:

Usefulness of Non-GAAP Financial Measures to Investors—The Company believes that presenting non-GAAP net income and non-GAAP earnings per share that exclude the impact of the Provision for Processing System Intrusion in addition to the related GAAP measures provides investors greater transparency to the information used by the Company’s management for its financial and operational decision-making and allows investors to see the Company’s results through the eyes of management. Additionally, the Company believes that the inclusion of these non-GAAP financial measures provides enhanced comparability in its financial reporting. The Company further believes that providing this information better enables its investors to understand the Company’s operating performance and underlying business fundamentals, and to evaluate the methodology used by management to evaluate and measure such performance.

This press release contains non-GAAP financial measures within the meaning of Regulation G promulgated by the Securities and Exchange Commission. Pursuant to Regulation G, a reconciliation of these non-GAAP financial measures with the comparable financial measures calculated in accordance with GAAP for the three and six months ended June 30, 2010 and 2009 follows:
