Exhibit 99.1

news release

Americas Region

Revenues from continuing operations from the Company’s Americas region, including operations in North America and offshore (Latin America, South Asia and the Asia Pacific region), increased 13.5% to $258.3 million, or 84.9% of total revenues, for the fourth quarter of 2012 compared to $227.6 million, or 82.4% of total revenues, in the prior year’s fourth quarter. The Alpine Access acquisition contributed $30.5 million in revenues to the Americas region in the fourth quarter of 2012. Excluding the revenue contribution from Alpine Access and on a constant currency basis, the 2.0% comparable decline in Americas’ revenues from continuing operations was largely a result of previously discussed end-of-life client programs, which more than offset the increase in demand from certain clients within the financial services, travel and communications verticals.

During the quarter, revenues from continuing operations generated from services provided offshore decreased to 43% from 49% in the same period last year principally due to a mix-shift in revenues to North America driven by Alpine Access, whose clients reside in and are serviced from the U.S. and Canada.

Sequentially, revenues from continuing operations generated from the Americas region increased 8.7% to $258.3 million in the fourth quarter of 2012 compared to $237.5 million, or 84.7% of total revenues, in the third quarter of 2012. On a constant currency basis, the 8.5% increase was principally due to full quarter’s revenue contribution from the Alpine Access acquisition in the fourth quarter versus a partial quarter’s revenue contribution in the third quarter due to the timing of the closing of the acquisition.

The Americas income from continuing operations for the fourth quarter of 2012 decreased 8.3% to $24.2 million, with an operating margin of 9.4% versus 11.6% in the comparable quarter last year. On a non-GAAP basis, the Americas operating margin from continuing operations was 11.6% versus 12.9% in the comparable quarter last year, with the decrease due to a combination of previously discussed end-of-life client programs, client program ramp expenses and investments in facility upgrades and transfers (see Exhibit 7 for reconciliation).

Sequentially, the Americas income from continuing operations for the fourth quarter of 2012 increased 11.7% to $24.2 million, with an operating margin of 9.4% versus 9.1% in the third quarter of 2012. On a non-GAAP basis, the Americas operating margin from continuing operations increased to 11.6% from 11.0% in the third quarter of 2012, driven by a full quarter’s revenue contribution from Alpine Access and expense leverage, coupled with cost savings associated with facility closures and lower professional services fees (see Exhibit 7 for reconciliation).

EMEA Region

Revenues from continuing operations from the Company’s Europe, Middle East and Africa (EMEA) region decreased 5.5% to $46.0 million, representing 15.1% of total revenues for the fourth quarter of 2012, compared to $48.7 million, or 17.6% of total revenues, in the prior year’s fourth quarter (EMEA’s revenues were down 3.8% on a constant currency basis). The constant currency decrease in EMEA revenues from continuing operations was largely a result of previously discussed end-of-life client programs and the effect of strategic actions (the Company’s planned exit from Ireland, South Africa and capacity rationalization in Amsterdam).

Sequentially, revenues from continuing operations from the Company’s EMEA region increased 6.9% to $46 million for the fourth quarter of 2012 compared to $43.0 million, or 15.3% of SYKES’ total revenues in the third quarter of 2012 (EMEA’s revenues were up 4.0% on a constant currency basis sequentially). The constant currency increase in EMEA revenues from continuing operations was driven largely by client demand within the technology, communications and financial services verticals.

The EMEA region’s income from continuing operations for the fourth quarter of 2012 was $3.6 million, or 7.9% of EMEA revenues, versus an operating loss of $4.9 million, or negative 10.1% of revenues, in the comparable quarter last year. On a non-GAAP basis, the operating margin from continuing operations increased to 6.2% from 1.8% in the same period last year. The more-than-three-fold increase was due to a combination of higher capacity utilization rate and cost savings resulting from the previously discussed strategic actions (see Exhibit 7 for reconciliation).

Sequentially, the EMEA region’s income from continuing operations for the fourth quarter of 2012 increased to $3.6 million, or 7.9% of revenues, from $2.4 million, or 5.5% of revenues, in the third quarter of 2012. On a non-GAAP basis, the EMEA operating margin from continuing operations was 6.2% versus 5.7% in the third quarter of 2012, with the increase due to better demand coupled with an increase in capacity utilization (see Exhibit 7 for reconciliation).

Corporate G&A Expenses

Corporate costs increased to $12.1 million, or 4.0% of revenues, in the fourth quarter of 2012, compared to $10.7 million, or 3.9% of revenues, in the comparable quarter last year, with the increase driven by a combination of professional services fees and integration costs associated with the Alpine Access acquisition. On a non-GAAP basis, corporate costs as a percentage of revenues remained unchanged on a comparable basis at 3.7% of revenues (see Exhibit 7 for reconciliation).

Sequentially, corporate costs decreased to $12.1 million, or 4.0% of revenues, in the fourth quarter of 2012, from $15.3 million, or 5.5% of revenues, in the third quarter of 2012, with the bulk of the transaction costs related to the Alpine Access acquisition occurring in the third quarter of 2012. On a non-GAAP basis, corporate costs decreased to $11.4 million, or 3.7% of revenues, from $11.9 million in the third quarter, or 4.2% of revenues, with the decrease due principally to lower variable incentive compensation (see Exhibit 7 for reconciliation).

Interest & Other Expense and Taxes

Interest and other expense for the fourth quarter of 2012 was $0.8 million versus interest and other income of $0.3 million in the comparable quarter last year, with the $1.1 million swing due to a combination of a subsidiary liquidation associated with the previously announced strategic actions in the EMEA region and realized and unrealized foreign currency transaction losses.

The Company’s effective tax rate in the fourth quarter 2012 was 11.0% versus 46.2% in the same period last year and below the estimated 18% provided in the Company’s November 2012 business outlook. The lower effective tax rate comparably and relative to the business outlook was driven principally by transaction and integration costs related to the Alpine Access acquisition, which lowered pre-tax income in a higher tax-rate jurisdiction.

On a non-GAAP basis, the fourth quarter 2012 effective tax rate from continuing operations was 18.0% compared to 42.0% in the same period last year and below the estimated 23% provided in the Company’s November 2012 business outlook. The decrease versus the year-ago period and relative to the November 2012 business outlook was due mainly to a shift in the geographic mix of earnings to lower tax rate jurisdictions.

2012 Financial Highlights

Liquidity and Capital Resources

Net cash provided by operating activities was up 37% to $31.2 million in the fourth quarter of 2012 from $22.7 million in the same period last year, with the increase driven by the Alpine Access acquisition and a lower comparable tax provision.
