CLEVELAND (August 2, 2016) – CBIZ, Inc. (NYSE: CBZ) today announced second-quarter and first-half results for the periods ended June 30, 2016.

For the 2016 second quarter, CBIZ reported revenue of $197.0 million, an increase of $12.0 million, or 6.5%, over the $185.0 million reported in the second quarter of 2015. Same-unit organic revenue increased by $4.9 million, or 2.7%, for the second quarter of 2016, compared with the same period a year ago. Newly acquired operations, net of divestitures, contributed $7.1 million to revenue in the 2016 second quarter. CBIZ reported second-quarter income from continuing operations of $8.4 million, or $0.16 per diluted share, compared with $6.7 million, or $0.13 per diluted share, in the second quarter of 2015. Adjusted EBITDA for the second quarter was $20.8 million, compared with $19.2 million for the second quarter of 2015.

For the six-month period ended June 30, 2016, CBIZ reported revenue of $421.3 million, an increase of $22.4 million, or 5.6%, over the $398.9 million recorded for the comparable six-month period a year ago. Same-unit organic revenue increased by $12.9 million, or 3.2%, for the first six months of 2016 compared with the same period a year ago. Acquisitions, net of divestitures, contributed $9.5 million, or 2.4%, to revenue growth for the first half of 2016. Income from continuing operations was $30.2 million, or $0.57 per

diluted share, for the first six months of 2016, compared with $26.2 million, or $0.51 per diluted share, for the first six months of 2015. Adjusted EBITDA was $64.1 million for the six months ended June 30, 2016, compared with $60.2 million for the six months ended June 30, 2015.

Jerry Grisko, CBIZ President and Chief Executive Officer, said, “We are pleased to see that the strong revenue growth and pre-tax margin expansion that we reported in the first quarter of 2016 has continued in the second quarter. Our Financial Services group continues to record strong growth, not only in our government health care consulting business, but also within our core accounting services business. Within our Employee Services group, we experienced continued organic revenue growth in our employee benefits and payroll businesses.”

“We were also pleased to complete two additional acquisitions since our last earnings report. The first, Flex-Pay Business Services, is a full-service payroll processing company located in Winston-Salem, N.C. In addition to an outstanding team of professionals and reputation for client service, Flex-Pay provides us the opportunity to expand the scope of services provided to the 3,600 clients that came with the transaction and is expected to bring total revenue in our payroll services business to over $40.0 million. The acquisition of Ed Jacobs and Associates, located in Cleveland, Tenn., brings strong talent and advances our commitment to building out a strong employee benefits practice that now represents over $100.0 million in revenue to CBIZ,” stated Grisko.

“The four acquisitions completed to date this year are expected to contribute approximately $34.0 million of revenue on an annual basis. In the past 12 months, we have completed six acquisitions that are expected to contribute approximately $42.0 million of annualized revenue. Our cash flow remains strong, our pipeline of potential acquisitions is very active, and we have the financial capacity to continue pursuing our strategic acquisition program, as well as conducting opportunistic share repurchases,” continued Grisko.

2016 Outlook

Grisko added, “Results for the first half are in line with our expectations and our outlook for full year 2016 continues to be very positive. To affirm our prior guidance, for full year 2016 we expect:

• “Total revenue growth within a range of 6% to 8% over 2015;

• “Fully diluted earnings per share to increase 12% to 15% over the reported $0.66 for 2015, or 9% to 12% over the normalized earnings per share of $0.68, which eliminates the impact of share equivalents related to the 2010 Convertible Notes that were fully retired in 2015; and

• “Adjusted EBITDA* growth is projected to be within a range of 7% to 9% over $87.0 million reported for 2015.”

*With respect to the Company’s full year guidance, the Company is unable to provide a reconciliation of Adjusted EBITDA, a non-GAAP financial measure, to operating income because interest expense, income tax expense, depreciation and amortization for the remainder of 2016, that would be included in such a reconciliation, have not yet occurred or are out of the Company’s control and/or cannot be reasonably predicted at this time. Therefore, pursuant to the “unreasonable efforts” exception in Item 10(e)(1)(i)(B) of Regulation S-K, the Company is not required to provide such a quantitative reconciliation.

(1) CBIZ sponsors a deferred compensation plan, under which a CBIZ employee’s compensation deferral is held in a rabbi trust and invested accordingly as directed by the employee. Income and expenses related to the deferred compensation plan are included in “Operating expenses” ($1.0 million expense in 2016 and $0.2 million income in 2015) and “Corporate general and administrative expenses” ($0.3 million expense in 2016 and $0.1 million income in 2015) and are directly offset by deferred compensation gains or losses in “Other income (expense), net” ($1.3 million income in 2016 and $0.3 million expense in 2015). The deferred compensation plan has no impact on “Income from continuing operations before income tax expense.”

(2) “Operating expenses” for the second quarter of 2016 include a reduction of $0.8 million related to state payroll tax incentives associated with an office relocation. No such reduction was available during the same period in 2015. The office relocation occurred during the second quarter of 2015, but the state payroll tax incentives were not recognized until the third quarter of 2015 due to the timing of the relocation.

(3) During the three months ended June 30, 2015, CBIZ recorded a non-operating charge of $0.8 million from the early retirement of $49.3 million face value of its 4.875% Convertible Senior Notes (“2010 Notes”) that matured on October 1, 2015. Also included in “Other income, net” for the three months ended June 30, 2016 and 2015, is expense of $0.5 million and income of less than $0.1 million, respectively, related to net increases/decreases in the fair value of contingent consideration related to CBIZ’s prior acquisitions.

(4) Refer to page eight of this press release for a reconciliation of the nearest generally accepted accounting principles (“GAAP”) financial measure to Non-GAAP financial measures, and for additional information as to the usefulness of the Non-GAAP financial measures to shareholders and investors.

(1) Effective January 1, 2016, CBIZ adopted Accounting Standards Update (“ASU”) 2015-03 and ASU 2015-15, “Interest - Imputation of Interest” which requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Upon the adoption of ASU 2015-03 and ASU 2015-15, the carrying amount of bank debt at December 31, 2015 has been retrospectively adjusted from $205.8 million to $203.9 million.

(2) Ratio is calculated as convertible notes, bank debt and notes payable divided by total stockholders’ equity. Upon the adoption of ASU 2015-03 and ASU 2015-15, the Company retrospectively adjusted the debt to equity ratio at December 31, 2015 from 48.3% to 47.8%.

(3) DSO is provided for continuing operations and represents accounts receivable, net at the end of the period, divided by trailing twelve month daily revenue. The Company has included DSO data because such data is commonly used as a performance measure by analysts and investors and as a measure of the Company’s ability to collect on receivables in a timely manner. DSO should not be regarded as an alternative or replacement to any measurement of performance under GAAP. DSO at June 30, 2015 was 84.
