WEX Inc. Reports Second Quarter 2013 Financial Results

Strong volume and transaction growth drive quarterly results to high end of guidance

SOUTH PORTLAND, Maine--(BUSINESS WIRE)--July 31, 2013--WEX Inc. (NYSE: WEX), a leading provider of corporate payment solutions, today reported financial results for the three months ended June 30, 2013.

Second Quarter Financial Results

Total revenue for the second quarter of 2013 increased 16% to $178.3 million from $153.1 million for the second quarter of 2012. Net income to common shareholders on a GAAP basis was $42.2 million, or $1.08 per diluted share, compared with $30.3 million, or $0.78 per diluted share, for the second quarter last year.

On a non-GAAP basis, the Company's adjusted net income for the second quarter of 2013 increased 5% to $41.1 million, or $1.05 per diluted share, from $39.1 million, or $1.00 per diluted share, for the same period a year ago. See Exhibit 1 for a full reconciliation of adjusted net income.

WEX uses fuel-price derivative instruments to mitigate financial risks associated with the variability in fuel prices in North America. For the second quarter of 2013, the Company's GAAP financial results include an unrealized pre-tax, non-cash, mark-to-market gain of $9.8 million dollars on these instruments.

Michael E. Dubyak, WEX chairman and chief executive officer said, “We continued to build on our momentum in the second quarter with revenue and adjusted net income increasing 16% and 5%, respectively, over last year. Key business wins, solid volume growth and favorable fuel prices drove our performance, as we continue to reinvest in our business to better position WEX for the future.”

“Executing on our growth strategy, we furthered our domestic fleet business with contributions from Fleet One and some key private label client wins. In addition, our investments in WEX Virtual are spearheading our expansion into the travel vertical, as we broadened our international presence within Europe, Asia-Pac and South America. With a robust pipeline of opportunities and a strong foundation for growth established in the first half of 2013, we are confident we can continue to deliver solid results while positioning WEX for long-term global success,” concluded Mr. Dubyak.

Second Quarter 2013 Performance Metrics

Where applicable, the performance metrics listed below include activity from Fleet One, acquired October 4, 2012, which positively impacted metrics for the second quarter of 2013.

• Average number of vehicles serviced worldwide was approximately 7.4 million, an increase of 10% from the second quarter of 2012.
• Total fuel transactions processed increased 12% from the second quarter of 2012 to 93.4 million. Payment processing transactions increased 15% to 73.8 million.
• Average expenditure per payment processing transaction increased 13.7% from the second quarter of 2012 to $85.78.
• U.S. retail fuel price decreased 2.4% to $3.70 per gallon from $3.79 per gallon in the second quarter of 2012.
• Total corporate card purchase volume grew $359 million, or 13%, to $3.2 billion compared to the second quarter of 2012.

Financial Guidance and Assumptions

“Strong growth across critical areas of our business combined with low credit losses and the addition of Fleet One drove our second quarter performance as compared to the prior year. We believe WEX is well-positioned to sustain this momentum in the back half of the year and our updated guidance for the full-year reflects this view. We expect to have a positive impact from higher fuel prices which we anticipate will be partially offset by a decline in foreign exchange rates,” said Steve Elder, WEX senior vice president and chief financial officer.

• For the third quarter of 2013, WEX expects revenue in the range of $186 million to $193 million and adjusted net income in the range of $45 million to $48 million, or $1.16 to $1.23 per diluted share.
• For the full year 2013, the Company expects revenue in the range of $718 million to $728 million and adjusted net income to be in the range of $167 million to $171 million, or $4.27 to $4.37 per diluted share.

Third quarter 2013 guidance is based on an assumed average U.S. retail fuel price of $3.74 per gallon, and approximately 39 million shares outstanding. Full-year 2013 guidance is based on an assumed average U.S. retail fuel price of $3.69 per gallon and approximately 39 million shares outstanding. The fuel prices referenced above are based on the applicable NYMEX futures price. WEX is assuming that exchange rates will remain in the range of the current spot rates.

The Company's guidance also assumes that third quarter 2013 fleet credit loss will range between 8 and 13 basis points, and that fleet credit loss for full year 2013 will range between 8 to 11 basis points.

Given the high likelihood that the pending merchant litigation settlement will be approved, the Company’s full-year guidance continues to assume a negative impact to the Company’s interchange rate, which is expected to be approximately 10 basis points for an 8 month period and began on July 29, 2013. We expect an impact of approximately $0.07 per share in 2013.

The Company's guidance does not reflect the impact of any future stock repurchases that may occur in 2013. In addition, this guidance excludes the impact of non-cash, mark-to-market adjustments on the Company's fuel-price-related derivative instruments and the amortization of purchased intangibles as well as the related tax impacts.

Additional Information

Exhibit 1 reconciles adjusted net income, which has not been determined in accordance with GAAP, to net income as determined in accordance with GAAP for the three and six months ended June 30, 2013 and 2012.

Any statements that are not statements of historical facts may be deemed to be forward-looking statements. When used in this news release, the words "may," "could," "anticipate," "plan," "continue," "project," "intend," "estimate," "believe," "expect" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such words. These forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially, including: the effects of general economic conditions on fueling patterns and the commercial activity of fleets; the effects of the Company’s business expansion and acquisition efforts; the Company’s failure to successfully integrate the businesses it has acquired; the failure of corporate investments to result in anticipated strategic value; the impact and range of credit losses; breaches of the Company’s technology systems and any resulting negative impact on our reputation, liability, or loss of relationships with customers or merchants; fuel price volatility; the Company’s failure to maintain or renew key agreements; failure to expand the Company’s technological capabilities and service offerings as rapidly as the Company’s competitors; the actions of regulatory bodies, including banking and securities regulators, or possible changes in banking regulations impacting the Company’s industrial bank and the Company as the corporate parent; the impact of foreign currency exchange rates on the Company’s operations, revenue and income; changes in interest rates; the impact of the Company’s outstanding bonds on its operations; financial loss if the Company determines it necessary to unwind its derivative instrument position prior to the expiration of a contract; the incurrence of impairment charges if our assessment of the fair value of certain of our reporting units changes; the uncertainties of litigation; as well as other risks and uncertainties identified in Item 1A. of the Company's annual report on Form 10-K filed with the Securities and Exchange Commission on March 1, 2013 and the Company's subsequent periodic and current reports. The Company's forward-looking statements and these factors do not reflect the potential future impact of any alliance, merger, acquisition, disposition or stock repurchases.

The Company disclaims any obligation to update any forward-looking statements as a result of new information, future events or otherwise.

Although adjusted net income is not calculated in accordance with generally accepted accounting principles (GAAP), this measure is integral to the Company's reporting and planning processes. The Company considers this measure integral because it eliminates the non-cash volatility associated with the fuel price related derivative instruments, and excludes the amortization of purchased intangibles, deferred loan cost associated with the extinguishment of debt, adjustments attributable to noncontrolling interest, the net impact of tax rate changes on the Company's deferred tax asset and related changes in the tax-receivable agreement including the former shareholder of RD Card Holdings Australia. Specifically, in addition to evaluating the Company's performance on a GAAP basis, management evaluates the Company's performance on a basis that excludes the above items because:

• Exclusion of the non-cash, mark-to-market adjustments on fuel-price related derivative instruments helps management identify and assess trends in the Company's underlying business that might otherwise be obscured due to quarterly non-cash earnings fluctuations associated with fuel-price derivative contracts;
• The non-cash, mark-to-market adjustments on derivative instruments are difficult to forecast accurately, making comparisons across historical and future quarters difficult to evaluate; and
• The amortization of purchased intangibles, deferred loan cost associated with the extinguishment of debt, adjustments attributable to noncontrolling interest, the net impact of tax rate changes on the Company's deferred tax asset and related tax refund due to former shareholders of RD Card Holdings Australia have no impact on the ongoing operations of the business.

For the same reasons, WEX believes that adjusted net income may also be useful to investors as one means of evaluating the Company's performance. However, because adjusted net income is a non-GAAP measure, it should not be considered as a substitute for, or superior to, net income, operating income or cash flows from operating activities as determined in accordance with GAAP. In addition, adjusted net income as used by WEX may not be comparable to similarly titled measures employed by other companies.

The tax impact of the foregoing adjustments is the difference between the Company’s U.S. GAAP tax provision and a pro forma tax provision based upon the Company’s adjusted net income before taxes. The methodology utilized for calculating the Company’s adjusted net income tax provision is the same methodology utilized in calculating the Company’s U.S. GAAP tax provision.

*The decline in the net payment process rate during Q4 2012 is primarily due to the acquisition of Fleet One in October of 2012.
