SOUTH PORTLAND, Maine--(BUSINESS WIRE)--April 27, 2016--WEX Inc. (NYSE:WEX), a leading provider of corporate payment solutions, today reported financial results for the three months ended March 31, 2016.

First Quarter 2016 Financial Results

Total revenue for the first quarter of 2016 increased 2% to $205.9 million from $202.3 million for the first quarter of 2015. Adjusting for constant currency, fuel prices, and fuel spreads, revenue for the first quarter increased approximately 12%. See Exhibit 1 for a full reconciliation of the previously mentioned adjustments. Net income to common shareholders on a GAAP basis was $23.1 million, or $0.59 per diluted share, compared with $22.3 million, or $0.57 per diluted share, for the first quarter last year.

On a non-GAAP basis, the Company's adjusted net income for the first quarter of 2016 decreased 18.7% to $37.6 million, or $0.97 per diluted share, from $46.2 million, or $1.19 per diluted share, for the same period a year ago. See Exhibit 2 for a full reconciliation of adjusted net income.

"I am pleased to report a solid start to the year, with first quarter results coming in ahead of our top and bottom line expectations. We generated strong organic growth across the business and continued to execute against our strategic priorities despite continued macroeconomic headwinds,” said Melissa Smith, WEX's president and chief executive officer. "Our focus on simplification through innovative technology, user-friendly tools and industry-leading customer service continues to fuel our growth."

Smith continued, “As we move through 2016, I look forward to maintaining this momentum to deliver organic growth in each of our segments. Additionally, we will continue to realize the benefits of our targeted investment strategy, further increase scale and extend our reach in both the U.S. and around the world. Overall, we feel very good about our position in the market as we continue to elevate our market leadership and enhance our product and service portfolio to meet the diverse needs of our global customers."

First Quarter 2016 Performance Metrics

• Average number of vehicles serviced worldwide was approximately 9.5 million, an increase of 3% from the first quarter of 2015.
• Total fuel transactions processed increased 2% from the first quarter of 2015 to 99.6 million. Payment processing transactions increased 9% to 89.1 million.
• Average expenditure per payment processing transaction decreased 25% from the first quarter of 2015 to $48.67.
• U.S. retail fuel price decreased 23% to $1.97 per gallon from $2.57 per gallon in the first quarter of 2015.
• Total Travel and Corporate Solution card purchase volume grew 18% to $4.9 billion, from $4.2 billion for the first quarter of 2015.

Financial Guidance and Assumptions

• For the second quarter of 2016, WEX expects revenue in the range of $216 million to $226 million and adjusted net income in the range of $37 million to $40 million, or $0.96 to $1.04 per diluted share.
• For the full year 2016, the Company expects revenue in the range of $879 million to $909 million and adjusted net income in the range of $158 million to $170 million, or $4.07 to $4.37 per diluted share.

Second quarter 2016 guidance is based on an assumed average U.S. retail fuel price of $2.20 per gallon, and approximately 39 million shares outstanding. Full-year 2016 guidance is based on an assumed average U.S. retail fuel price of $2.14 per gallon and approximately 39 million shares outstanding. The fuel prices referenced above are based on the applicable NYMEX futures price.

The Company's guidance also assumes that second quarter 2016 fleet credit loss will range between 7 and 12 basis points, and full year 2016 fleet credit loss will range between 10 and 15 basis points. The Company's full year 2016 guidance excludes the impact and closing expenses of the Electronic Funds Source ("EFS") acquisition, due to the uncertain timing of the regulatory review process.

The Company's guidance excludes the impact of certain acquisition related costs, non-cash, mark-to-market adjustments on the Company's fuel-price-related derivative instruments, stock-based compensation, restructuring charges, gain on divestitures and the amortization of purchased intangibles as well as the related tax and non-controlling interest impacts of the forgoing adjustments.

Additional Information

Exhibit 1 reconciles revenue adjusted for foreign exchange impact ("FX"), fuel prices, and fuel spread and their tax impacts and adjusted net income for the impact of FX, fuel prices, fuel spreads and fuel hedges and their tax impacts, which has not been determined in accordance with GAAP for the three months ended March 31, 2016 and 2015.

Exhibit 2 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 months ended March 31, 2016 and 2015.

Management uses the non-GAAP measures presented within this news release to evaluate the Company's performance on a comparable basis, to eliminate the volatility associated with its derivative instruments and to measure the amount of cash that is available for making payments on the Company's financing debt and for discretionary purposes. Management believes that investors may find these measures useful for the same purposes, but cautions that they should not be considered a substitute for, or superior to, disclosure in accordance with GAAP.

WEX has historically used fuel-price derivative instruments to mitigate financial risks associated with the variability in fuel prices in North America. For the first quarter of 2016, the Company's GAAP financial results include an unrealized pre-tax, non-cash, mark-to-market loss of $5.0 million on these instruments.

To provide investors with additional insight into its operational performance, WEX has included in this news release a table of selected non-financial metrics for the five quarters ended March 31, 2016. This table is presented as Exhibit 3. The Company is also providing selected segment revenue information for the three months ended March 31, 2016 and 2015 in Exhibit 3.

To determine revenue on a FX adjusted basis, revenue from entities whose functional currency is not denominated in U.S. dollars, as well as revenue from purchase volume transacted in non-US denominated currencies, were translated using the weighted average exchange rates for the same period in the prior year. To determine revenue on a PPG adjusted basis, revenue was adjusted based on the average retail price of fuel for the same period in the prior year for the portion of our business that earns revenue based on a percentage of fuel spend. For the portions of our business that earn revenue based on margin spreads, revenue was adjusted to the comparable margin from the prior year.

Although FX and PPG adjusted revenue 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 volatility associated with foreign exchange rates and fuel price. Specifically, in addition to evaluating the Company's performance on a GAAP basis, management evaluates the Company's performance on a FX and PPG adjusted revenue basis as management considers this an important measure of operational performance.

To determine adjusted net income on a FX adjusted basis, revenue and expenses from entities whose functional currency is not denominated in U.S. dollars, as well as revenue and variable expenses from purchase volume transacted in non-US denominated currencies, were translated using the weighted average exchange rates for the same period in the prior year, net of tax.

To determine adjusted net income on a PPG adjusted basis, revenue, and expenses variable to changes in fuel prices, were adjusted based on the average retail price of fuel for the same period in the prior year for the portion of our business that earns revenue based on a percentage of fuel spend. For the portions of our business that earn revenue based on margin spreads, revenue was adjusted to the comparable margin from the prior year. Realized gains or losses on fuel price related hedges were removed from both current and the same period in the prior year.

Although FX and PPG adjusted net income is not calculated in accordance with GAAP, this measure is integral to the Company's reporting and planning processes. The Company considers this measure integral because it eliminates the volatility associated with foreign exchange rates and fuel price. Specifically, in addition to evaluating the Company's performance on a ANI basis, management evaluates the Company's performance on a FX and PPG adjusted ANI basis as management considers this an important measure of operational performance.

Although adjusted net income is not calculated in accordance with 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 other specified items that the Company's management excludes in evaluating the Company's performance. 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:

• The Company considers certain acquisition-related costs, including certain financing costs, financing fees and ticking fees, investment banking fees, warranty and indemnity insurance, acquisition related expenses and amortization of acquired intangibles, as well as gains and losses from divestitures to be unpredictable, dependent on factors that may be outside of our control and unrelated to the continuing operations of the acquired or divested business or the Company. In prior periods not reflected above, the Company has adjusted for goodwill impairments, acquisition related assets impairments and adjustment to the tax receivable agreement. In addition, the size and complexity of an acquisition, which often drives the magnitude of acquisition-related costs, may not be indicative of such future costs. The Company believes that excluding acquisition-related costs and gains or losses of divestitures facilitates the comparison of our financial results to the Company's historical operating results and to other companies in our industry.
• Stock-based compensation is different from other forms of compensation, as it is a non-cash expense. For example, a cash salary generally has a fixed and unvarying cash cost. In contrast, the expense associated with an equity-based award is generally unrelated to the amount of cash ultimately received by the employee, and the cost to us is based on a stock-based compensation valuation methodology and underlying assumptions that may vary over time.
• Restructuring charges are related to employee termination benefits from certain identified initiatives to further streamline the business, improve the Company's efficiency, non-reoccurring costs to create synergies, and to globalize the Company's operations, all with an objective to improve scale and increase profitability going forward. We exclude these items when evaluating our continuing business performance as such items are not consistently occurring and do not reflect expected future operating expense, nor provide meaningful insight into the fundamentals of current or past operations of our business.
• 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-related 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.
• Net foreign currency gains and losses primarily result from the remeasurement to functional currency of foreign currency cash, receivable and payable balances, certain intercompany notes and any gain or loss on foreign currency hedges relating to these items. The exclusion of these items helps management compare changes in operating results between periods that might otherwise be obscured due to currency fluctuations.
• The adjustments attributable to non-controlling interests, including adjustments to the redemption value of a non-controlling interest, have no significant 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 forgoing 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 Company is unable to reconcile our adjusted net income guidance to the comparable GAAP measure because of the difficulty in predicting the amounts to be adjusted.
