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 4.0% to $285.5 million, or 81.6% of total revenues, for the fourth quarter of 2014 compared to $274.6 million, or 81.9% of total revenues, in the same prior year period. This comparable growth was driven largely by the expansion of existing and some new client programs across the communications, technology and healthcare verticals more than offsetting mixed demand within the financial services and transportation verticals. On a constant currency basis, fourth quarter 2014 Americas revenues increased 5.8% comparably due to the factors noted above.

Sequentially, revenues generated from the Americas region were up 6.8% to $285.5 million from $267.4 million, or 80.4% of total revenues, in the third quarter of 2014 due largely to the above-mentioned factors. On a constant currency basis, fourth quarter 2014 Americas revenues increased 7.9% over third quarter.

The Americas income for the fourth quarter of 2014 increased 46.7% to $41.5 million, with an operating margin of 14.5% versus 10.3% in the comparable quarter last year. The Americas income from operations for the fourth quarter of 2014 includes the facility-sale gain of $2.6 million, or 90 basis points of operating margin contribution. On a non-GAAP basis, which excludes the facility-sale gain, the Americas operating margin increased to 14.9% from 11.8% in the comparable quarter last year, driven by higher demand, improved capacity utilization and better expense leverage, coupled with a favorable foreign exchange impact (approximately 110 basis points) (see Exhibit 7 for reconciliation).

Sequentially, the Americas income for the fourth quarter of 2014 increased 46.6% to $41.5 million, with an operating margin of 14.5% versus 10.6% in the third quarter of 2014. The Americas income from operations for the fourth quarter of 2014 includes the facility-sale gain of $2.6 million, or 90 basis points of operating margin contribution. On a non-GAAP basis, which excludes the facility-sale gain, the Americas operating margin increased to 14.9% from 12.1%. The increase was principally due to the above-mentioned factors, coupled with agent productivity gains and favorable foreign exchange impact (approximately 40 basis points) (see Exhibit 7 for reconciliation).

EMEA Region

Revenues from the Company’s Europe, Middle East and Africa (EMEA) region increased 6.0% to $64.4 million, representing 18.4% of total revenues for the fourth quarter of 2014, compared to $60.8 million, or 18.1% of total revenues, in the same prior year period, driven largely by the expansion of existing and some new client programs across the communications and technology verticals. On a constant currency basis, EMEA revenues increased 15.8% on a comparable basis.

Sequentially, revenues from the Company’s EMEA region decreased 1.3% to $64.4 million, or 18.4% of SYKES’ total revenues, versus $65.3 million, or 19.6% of SYKES’ total revenues, in the third quarter of 2014. On a constant currency basis, EMEA revenues increased 4.9% sequentially, driven by higher demand from existing client programs particularly within the technology vertical.

The EMEA region’s income for the fourth quarter of 2014 was $4.8 million, or 7.4% of EMEA revenues, versus $2.7 million, or 4.4% of revenues, in the comparable quarter last year. On a non-GAAP basis, the operating margin was 7.4% versus 5.0% in the same period last year, with the margin increase driven by a combination of higher demand, higher capacity utilization, productivity improvements on programs launched last year and expense leverage (see Exhibit 7 for reconciliation).

Sequentially, the EMEA region’s income for the fourth quarter of 2014 was $4.8 million, or 7.4% of EMEA revenues, versus $7.0 million, or 10.7% of revenues, in the third quarter of 2014. On a non-GAAP basis, the EMEA operating margin was 7.4% versus 10.5% due to costs associated with facility expansion and management additions (see Exhibit 7 for reconciliation).

Corporate G&A Expenses

Corporate G&A expenses increased to $13.7 million, or 3.9% of revenues, in the fourth quarter of 2014, compared to $11.7 million, or 3.5% of revenues, in the comparable quarter last year, with the increase driven largely by higher incentive compensation due to strong operating performance both on a GAAP and non-GAAP basis (see Exhibit 7 for reconciliation).

Sequentially, corporate G&A expenses increased to $13.7 million from $13.2 million in the third quarter of 2014, however, it declined slightly as a percentage of revenues to 3.9% from 4.0% in the third quarter of 2014 both on a GAAP and non-GAAP basis (see Exhibit 7 for reconciliation).

Other Income (Expense) and Taxes

Total other (expense), net for the fourth quarter of 2014 totaled $1.5 million compared to $1.3 million for the same period in the prior year. Total other (expense), net was higher in the fourth quarter of 2014 compared to the same period last year with the increase primarily attributable to realized and unrealized foreign currency transaction losses.

The Company recorded an effective tax rate of 27.6% for the fourth quarter of 2014 versus 38.8% in the same period last year and versus the estimated 24% provided in the Company’s November 2014 business outlook. The effective tax rate differential on a comparable basis and relative to the business outlook was due to prior year taxation of offshore gains on derivatives and foreign exchange related to inter-company loans and a shift in the geographic mix of earnings between low and high tax rate jurisdictions, driven partly by the facility sale in the U.S.

On a non-GAAP basis, the fourth quarter 2014 effective tax rate was 27.7% compared to 37.2% in the same period last year and above the estimated 25% provided in the Company’s November 2014 business outlook (see Exhibit 11 for reconciliation). The effective tax rate differential on a comparable basis and relative to the business outlook, both of which do not include the facility sale, was due to the aforementioned factor.

2014 Financial Highlights

Liquidity and Capital Resources

The Company’s balance sheet at December 31, 2014 remained strong with cash and cash equivalents of $215.1 million, of which $194.4 million, or 90.3% of the cash balance, was held in international operations and may be subject to additional taxes if repatriated to the United States, including withholding tax applied by the country of origin and U.S. taxes on the dividend income. In 2014, net cash provided by operating activities was up 9.3% compared to 2013 driven by higher net income and non-cash items, which was partially moderated by the timing of working capital flux. Also, in 2014, the Company repurchased approximately 630 thousand shares at an average price of approximately $19.92 per share. At year end, the Company had $75.0 million in borrowings outstanding, down from $98 million at the beginning of the year with $170.0 million still remaining available under its credit facility.
