Exhibit 99.1

1

Americas Region

Revenues from the Company’s Americas region, including operations in North America and offshore (Latin America, South Asia and the Asia Pacific region), increased 22.5% to $320.9 million, or 83.6% of total revenues, for the first quarter of 2017 compared to $262.1 million, or 81.7% of total revenues, in the same prior-year period. Excluding the acquisition of Clearlink, which added $43.1 million in revenues in the quarter, constant currency organic revenues (a non-GAAP measure, see Exhibit 9 for reconciliation) for the first quarter of 2017 in the Americas increased 6.1% comparably, with the increased demand driven by new client wins as well as existing and new program expansion across the communications, financial services, transportation and leisure, technology and other verticals.

Sequentially, revenues generated from the Americas region decreased 2.0% to $320.9 from $327.5 million, or 84.2% of total revenues, in the fourth quarter of 2016. On a constant currency basis (a non-GAAP measure, see Exhibit 9 for reconciliation) for the first quarter of 2017, the Americas revenue decreased 2.0% over the fourth quarter driven by a higher component of seasonal demand more than offsetting new client wins as well as existing and new program expansion within the financial services and transportation and leisure verticals.

The Americas income from operations for the first quarter of 2017 increased 15.0% to $37.9 million, with an operating margin of 11.8% versus 12.6% in the comparable quarter last year. On a non-GAAP basis, the Americas operating margin was 13.5% versus 13.9% in the comparable quarter last year, with the delta mostly driven by previously discussed ramp-related staffing inefficiencies more-than-offsetting the contributions from Clearlink and the calendar shift in Easter holiday (see Exhibit 6 for reconciliation).

Sequentially, the Americas income from operations for the first quarter of 2017 decreased 3.9% to $37.9 million, with an operating margin of 11.8% versus 12.1% in the fourth quarter of 2016 driven by the factors mentioned above. On a non-GAAP basis, the Americas operating margin was 13.5% versus 13.8% in the fourth quarter of 2016, with the delta due to the above-mentioned factors (see Exhibit 6 for reconciliation).

EMEA Region

Revenues from the Company’s Europe, Middle East and Africa (EMEA) region increased 7.6% to $63.1 million, representing 16.4% of total revenues, for the first quarter of 2017, compared to $58.6 million, or 18.3% of total revenues, in the same prior year period. On a constant currency

2

basis (a non-GAAP measure, see Exhibit 9 for reconciliation), EMEA revenues increased 15.9% on a comparable basis driven by new client wins as well as existing and new program expansion principally within the technology and communications verticals.

Sequentially, revenues from the Company’s EMEA region increased 2.4% to $63.1 million, or 16.4% of SYKES’ total revenues, versus $61.6 million, or 15.8% of SYKES’ total revenues, in the fourth quarter of 2016. On a constant currency basis (a non-GAAP measure, see Exhibit 9 for reconciliation), EMEA revenues increased 4.2% sequentially, driven by new client wins as well as existing and new program expansion within the technology and communications verticals.

The EMEA region’s income from operations for the first quarter of 2017 increased 63.6% to $5.6 million, with an operating margin of 8.8% versus 5.8% in the comparable quarter last year. On a non-GAAP basis, the operating margin increased to 9.7% from 6.4% in the year-ago period due to higher demand resulting in higher agent throughput and the calendar shift in Easter holiday (see Exhibit 6 for reconciliation).

Sequentially, the EMEA region’s income from operations for the first quarter of 2017 increased 19.2% to $5.6 million, with an operating margin of 8.8% versus 7.6% in the fourth quarter of 2016. On a non-GAAP basis, the EMEA operating margin was 9.7% versus 8.5% in the fourth quarter of 2016 due to above-mentioned factors (see Exhibit 6 for reconciliation).

Other

Other (loss) from operations, which includes corporate and other costs, increased to $17.5 million, or 4.6% of revenues in the first quarter of 2017, compared to $16.1 million, or 5.0% of revenues in the prior year period, with the percentage decrease largely a result of costs leveraged across a larger revenue base resulting from the Clearlink acquisition. On a non-GAAP basis, Other (loss) from operations remained unchanged at 4.6% of revenues on a comparable basis due to factors stated above (see Exhibit 6 for reconciliation).

Sequentially, Other (loss) from operations increased to $17.5 million, or 4.6% of revenues, from $15.3 million, or 3.9% of revenues, in the fourth quarter of 2016, with the sequential increase related to payroll tax resets at the beginning of the year as well as investments in information technology, financial ERP system and new leadership in operations, coupled with an increase in professional services fees. On a non-GAAP basis, Other (loss) from operations increased to 4.6% of revenues in the first quarter of 2017 from 3.9% in the fourth quarter of 2016 due to above-stated factor (see Exhibit 6 for reconciliation).

Other Income (Expense) and Taxes

Total other income (expense), net for the first quarter of 2017 was ($0.7) million compared to ($0.1) million for the same period in the prior year, with the increase principally due to higher interest expense from higher average debt balance on a comparable basis in the first quarter of 2017 (a non-GAAP measure, see Exhibit 5 for reconciliation).

The Company recorded an effective tax rate of 26.1% for the first quarter of 2017 versus 30.8% in the same period last year and below the estimated 31.0% provided in the Company’s February 2017 business outlook. The rate differential compared to the same period last year and relative to the business outlook was due to the recognition of a $0.9 million tax benefit resulting from the adoption of Accounting Standards Update (“ASU”) 2016-09 on January 1, 2017 related to share-based compensation accounting, coupled with shifts in the geographic mix of earnings to lower tax rate jurisdictions.

On a non-GAAP basis, the first quarter 2017 effective tax rate was 27.9% compared to 31.7% in the same period last year and below the estimated 33.0% provided in the Company’s February 2017 business outlook (see Exhibit 8 for reconciliation) due to the above-mentioned factors.

Liquidity and Capital Resources

The Company’s balance sheet at March 31, 2017 remained strong with cash and cash equivalents of $286.8 million, of which approximately 92.0%, or $264.0 million, was held in international operations and is deemed to be indefinitely reinvested offshore. In first quarter 2017, net cash provided by operating activities was up 35.7% on a comparable basis to a record $37.2 million, driven mostly by strong operating performance in the quarter and working capital swing factors, coupled with the contribution from Clearlink. At March 31, 2017, the Company had $267.0 million in borrowings outstanding, with $173.0 million available under its $440.0 million credit facility.

New Business Wins Stemming from the Acquisition of a Global 2000 Telecommunications Services Provider’s Operating Assets

SYKES signed a definitive asset purchase agreement on April 24, 2017, to acquire a telecommunications services provider’s customer engagement assets that service third-party clients. The provider is an existing client of SYKES and has grown rapidly over a very short period to becoming a top-10 client in 2016.

The rationale behind the acquisition is as follows:

The cash purchase price is $7.5 million and is expected to be funded through the Company’s existing cash balance. These assets generated estimated revenues of approximately $80 million in 2016. The Company anticipates the transaction to be neutral on a diluted earnings per share basis in 2017 as it focuses on fine-tuning the acquired operations to a level of performance consistent with its approach after having been operated as a non-core asset. The Company plans to update its business outlook regarding the impact of this transaction when it reports its second quarter 2017 financial results.

Business Outlook

The assumptions driving the business outlook for the second quarter and full-year 2017 are as follows:

--The Company’s business outlook does not reflect any contribution from the asset acquisition. The Company expects to provide an update on the revenue contribution from the transaction when it reports its second quarter 2017 financial results;

--The Company’s business outlook for the second quarter of 2017 relative to the reported first quarter 2017 financial results reflects a combination of fewer workdays, the calendar shift in the Easter holiday to the second quarter, some demand seasonality associated with some of its clients, and ramp costs associated with staffing for demand for the third quarter of 2017. For full year 2017, the Company is increasing its diluted earnings per share range relative to the business outlook provided previously on February 27, 2017 while keeping its revenues range-bound;

--The Company’s revenues and earnings per share assumptions for the second quarter and full year 2017 are based on foreign exchange rates as of April 2017. Therefore, the continued volatility in foreign exchange rates between the U.S. dollar and the functional currencies of the markets the Company serves could have a further impact, positive or negative, on revenues and both GAAP and non-GAAP earnings per share relative to the business outlook for the second quarter and full-year as discussed above;

4

--The Company anticipates total other interest income (expense), net of approximately ($1.5) million for the second quarter and ($5.2) million for the full year 2017. The second quarter and full year 2017 amounts include the accretion of the contingent consideration of approximately $0.03 million and $0.1 million, respectively, associated with Clearlink. The amounts in the other interest income (expense), however, exclude the potential impact of any future foreign exchange gains or losses; and

--The Company expects a reduction in its full-year 2017 effective tax rate relative to the outlook provided previously on February 27, 2017, with the decline due to a shift in the geographic mix of earnings to lower tax rate jurisdictions coupled with tax benefit resulting from the adoption of Accounting Standards Update (“ASU”) 2016-09.

Considering the above factors, the Company anticipates the following financial results for the three months ending June 30, 2017:

For the twelve months ending December 31, 2017, the Company anticipates the following financial results:

Conference Call

The Company will conduct a conference call regarding the content of this release tomorrow, May 9, 2017, at 10:00 a.m. Eastern Standard Time. The conference call will be carried live on the Internet. Instructions for listening to the call over the Internet are available on the Investors page of SYKES’ website at www.sykes.com. A replay will be available at this location for two weeks. This press release is also posted on the SYKES website at http://investor.sykes.com/investor-relations/Investor-Resources/Investor-Relations-Home/default.aspx.

Non-GAAP Financial Measures

Non-GAAP indicators of performance are not measures of financial performance under U.S. Generally Accepted Accounting Principles (“GAAP”) and should not be considered a substitute for measures determined in accordance with GAAP. The Company, however, uses non-GAAP measures as a way to assist readers in further understanding the Company’s results. The Company believes these non-GAAP financial measures are important indicators of performance as they are intrinsic to how management evaluates and rewards performance from its underlying operations. Constant currency organic revenue growth, which is a non-GAAP measure, for instance, facilitates comparability between time periods as this presentation allows the Company

5

to isolate the effect of acquisition-related revenues and exchange rate differences by assuming a constant exchange rate between periods for translation. Similarly, amortization of intangible assets and depreciation of the step up in value of purchased tangible assets are excluded for purposes of calculating the non-GAAP financial measures – including but not limited to non-GAAP operating margins, non-GAAP tax rate, non-GAAP net income, non-GAAP net income per diluted share and non-GAAP income from operations – because the Company does not acquire businesses on a predictable cycle and the exclusion facilitates a more meaningful evaluation of current operating performance and comparison to operating performance in other periods as well as performance relative to its peers who are not acquisitive or as acquisitive. The Company also excludes the impact or any corresponding reversals of material restructurings approved by the appropriate level of management, gain or loss on sale of facilities, release of cumulative translation adjustment (CTA), lease obligations and facility exit costs, severance and related costs, non-cash impairment charges, deal and integration costs associated with an acquisition and accretion of interest on contingent consideration of an acquisition from non-GAAP Income (loss) from operations and non-GAAP net income because the amounts are not reflective of ongoing operating results and do not contribute to a meaningful evaluation of current operating performance or comparison to operating performance in other periods. Refer to the exhibits in the release for detailed reconciliations.
