-- Revenue $136.9 million, up 9% -- Base Business growth of 13%; Event Business decline of 8% -- Field and Industrial Services revenue growth of 4% -- Operating income growth of 28% -- Net income of $13.2 million -- Diluted earnings per share of $0.60; Adjusted earnings per share of $0.61, up 61% -- Adjusted EBITDA of $31.7 million, up 15%

2018 BUSINESS OUTLOOK REAFFIRMED:

BOISE, Idaho, Aug. 02, 2018 (GLOBE NEWSWIRE) -- US Ecology, Inc. (NASDAQ: ECOL) (“the Company”) today reported total revenue of $136.9 million and net income of $13.2 million, or $0.60 per diluted share, for the quarter-ended June 30, 2018. Adjusted earnings per share, which excludes foreign currency translation gains and losses, and business development expenses, was $0.61 per diluted share in the second quarter of 2018, up 61% from the second quarter of 2017.

“Business conditions continue to improve, supporting our growth expectations for the year,” commented Chairman and Chief Executive Officer, Jeff Feeler. “We saw increased strength in our Environmental Services Base Business, with revenue up 13% compared to the second quarter of 2017. Even after backing out the recovery at a treatment facility that was temporarily shut down in the second quarter of 2017, our Base Business was up 9% in the second quarter of 2018. Our Environmental Services Event Business was down 8% in the second quarter of 2018 as a large multi-year project that would have replaced projects completed in the prior year did not ship as anticipated. This project commenced shipments in July and volume initially expected in the first half of 2018 should now be recognized in the second half of 2018. Our Field and Industrial Services segment also delivered another quarter of solid revenue growth, up 4% compared to the second quarter last year, in-line with our expectations.”

For the second quarter of 2018, Environmental Services (“ES”) segment revenue was $99.0 million, up from $89.6 million in the second quarter of 2017. This increase consisted of 9% growth in treatment and disposal (“T&D”) revenue and 13% growth in transportation revenue compared to the second quarter of 2017. Field and Industrial Services (“FIS”) segment revenue was $38.0 million for the second quarter of 2018, up 4% from $36.5 million in the same period of 2017, reflecting continued growth in our Small Quantity Generation business lines, as well as stronger overall market conditions.

Gross profit for the second quarter of 2018 was $41.4 million, up 15% from $35.9 million in the same quarter last year. ES segment gross profit was $35.9 million in the second quarter of 2018, up from $30.7 million in the same quarter of 2017. T&D gross margin for the ES segment was 42% for the second quarter of 2018, up from 38% for the second quarter of 2017. Gross profit for the FIS segment in the second quarter of 2018 was $5.5 million, up from $5.2 million in the second quarter of 2017. Gross margin for the FIS segment was 15% in second quarter of 2018, compared to 14% in the second quarter last year.

Selling, general and administrative (“SG&A”) expense for the second quarter of 2018 was $21.2 million, compared with $20.0 million in the same quarter last year. The increase in SG&A expense was primarily due to higher labor and incentive compensation.

Operating income for the second quarter of 2018 was $20.3 million compared to $15.9 million in the second quarter of 2017, an increase of 28%.

Net interest expense for the second quarter of 2018 was $2.9 million, down from $8.5 million in the second quarter of 2017. The decrease was the result of a non-cash charge of $5.5 million associated with the second quarter 2017 write-off of deferred financing fees related to the refinancing of our former credit facility.

The Company’s consolidated effective income tax rate for the second quarter of 2018 was 24.4%, down from 35.0% for the second quarter of 2017. The decrease was primarily due to tax reform passed in the fourth quarter of 2017, which reduced the U.S. corporate tax rate from 35% to 21%.

Net income for the second quarter of 2018 was $13.2 million, or $0.60 per diluted share, compared to net income of $5.0 million, or $0.23 per diluted share, in the second quarter of 2017. Tax reform favorably impacted net income by approximately $0.08 per diluted share compared to the second quarter of 2017. Adjusted earnings per share, which excludes foreign currency translation gains and losses, business development expenses, and the non-cash write-down of deferred financing fees in the second quarter of 2017, was $0.61 per diluted share in the second quarter of 2018, compared to $0.38 per diluted share in the second quarter of 2017.

Adjusted EBITDA for the second quarter of 2018 was $31.7 million, up 15% from $27.6 million in the same period last year.

Reconciliations of earnings per diluted share to adjusted earnings per diluted share and net income to adjusted EBITDA are attached as Exhibit A to this release.

Year-To-Date Results

Total revenue for the first six months of 2018 was $257.0 million, up 9% from $236.3 million in the first six months of 2017. Revenue for the ES segment was $185.4 million for the first six months of 2018, up from $170.9 million in the same period of 2017. This consisted of a 7% increase in T&D revenue and a 13% increase in transportation revenue compared to the first six months of 2017. Revenue for the FIS segment was $71.5 million for the first six months of 2018, up 9% from $65.4 million in the same period of 2017, reflecting continued growth in our Total Waste Management and Small Quantity Generation business lines as well as stronger overall market conditions.

Gross profit for the first six months of 2018 was $77.1 million, up 14% from $67.8 million in the same period last year. Gross profit for the ES segment was $68.4 million in the first six months of 2018, up from $59.4 million in the first six months of 2017. T&D gross margin for the ES segment was 41% for the first six months of 2018 compared to 38% for the prior year period, reflecting the March 2017 shutdown of one of our large treatment facilities due to severe wind damage. Gross profit for the FIS segment in the first six months of 2018 was $8.8 million, up from $8.4 million in the first six months of 2017. Gross margin for the FIS segment was 12% in the first six months of 2018, compared to 13% in the first six months of 2017, driven primarily by increased costs experienced in the Industrial Services business in the first quarter of 2018 due to harsher winter conditions.

SG&A expense for the first six months of 2018 was $43.4 million compared with $39.7 million in the same period last year. The increase in SG&A expense was primarily due to higher labor and incentive compensation.

Operating income for the first six months of 2018 was $33.7 million, up 20% from $28.1 million in the first six months of 2017.

Net interest expense for the first six months of 2018 was $5.7 million, down from $12.6 million in the first six months of 2017. Interest expense for the first six months of 2017 included the non-cash charge of $5.5 million associated with the write-off of deferred financing fees related to the refinancing of our former credit facility in April 2017. Excluding the non-cash deferred financing fees charge, interest expense decreased compared to the first six months of 2017 as a result of a lower interest rate on our new credit facility.

The Company’s consolidated effective income tax rate for the first six months of 2018 was 25.7%, down from 36.2% for the first six months of 2017. This decrease is primarily due to tax reform passed in the fourth quarter of 2017, which reduced the U.S. corporate tax rate from 35% to 21%.

Net income for the first six months of 2018 was $22.5 million, or $1.02 per diluted share, compared to $10.2 million, or $0.47 per diluted share, in the first six months of 2017. Adjusted earnings per share, which excludes the gain on the issuance of a property easement, foreign currency translation gains and losses, the non-cash write-down of deferred financing fees, and business development expenses, was $0.97 per diluted share in the first six months of 2018 compared to $0.61 per diluted share for the first six months of 2017. Adjusted EBITDA for the first six months of 2018 was $56.2 million, up 10% from $51.1 million in the same period last year. Reconciliations of earnings per diluted share to adjusted earnings per diluted share and net income to adjusted EBITDA are attached as Exhibit A to this release.

2018 OUTLOOK

“Business conditions in the first half of 2018 remain consistent with our expectations, with strong underlying improvement across many of our service lines,” commented Feeler. “Our Base Business continues to lead the way, with high-single-digit growth rates, even after excluding the recovery of our treatment facility that was temporarily shut down last year. We have been successful at securing Event Business opportunities to add to our pipeline. This has helped offset unexpected delays with one of our multi-year cleanup sites in the first half of 2018. Our Field and Industrial Services segment is benefitting from contracts won in 2017, although given the slower than anticipated pace of implementation, some of the contracts have yet to produce the expected results. Overall, the strong fundamentals and improving business conditions have us on track to meet our previously issued 2018 guidance.”

Based on our first half results and current outlook for the balance of 2018 the Company reaffirms its previously issued 2018 Adjusted EBITDA guidance range of $122 million to $128 million and its diluted earnings per share guidance of $2.15 to $2.34. The Company’s earnings guidance excludes the gain on the issuance of a property easement, business development expenses and foreign currency gains and losses.

The following table reconciles our projected net income to our adjusted EBITDA guidance range:

EXHIBIT ANon-GAAP Results and Reconciliation

US Ecology reports adjusted EBITDA, Pro Forma adjusted EBITDA and adjusted earnings per diluted share results, which are non-GAAP financial measures, as a complement to results provided in accordance with generally accepted accounting principles in the United States (GAAP) and believes that such information provides analysts, stockholders, and other users information to better understand the Company’s operating performance. Because adjusted EBITDA, Pro Forma adjusted EBITDA and adjusted earnings per diluted share are not measurements determined in accordance with GAAP and are thus susceptible to varying calculations they may not be comparable to similar measures used by other companies. Items excluded from adjusted EBITDA, Pro Forma adjusted EBITDA and adjusted earnings per diluted share are significant components in understanding and assessing financial performance.

Adjusted EBITDA, Pro Forma adjusted EBITDA and adjusted earnings per diluted share should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity. Adjusted EBITDA, Pro Forma adjusted EBITDA and adjusted earnings per diluted share have limitations as analytical tools and should not be considered in isolation or a substitute for analyzing our results as reported under GAAP. Some of the limitations are:

-- Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; -- Adjusted EBITDA does not reflect our interest expense, or the requirements necessary to service interest or principal payments on our debt; -- Adjusted EBITDA does not reflect our income tax expenses or the cash requirements to pay our taxes; -- Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments; -- Although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and adjusted EBITDA does not reflect cash requirements for such replacements; and -- Pro Forma adjusted EBITDA does not reflect our business development expenses, which may vary significantly quarter to quarter.

Adjusted EBITDA

The Company defines adjusted EBITDA as net income before interest expense, interest income, income tax expense/benefit, depreciation, amortization, stock-based compensation, accretion of closure and post-closure liabilities, foreign currency gain/loss, and other income/expense, which are not considered part of usual business operations.

Pro Forma adjusted EBITDA

The Company defines Pro Forma adjusted EBITDA as adjusted EBITDA (see definition above) plus business development expenses incurred during the period. We believe Pro Forma adjusted EBITDA is helpful in understanding our business and how it relates to our 2018 guidance which does not include business development expenses.

The following reconciliation itemizes the differences between reported net income and adjusted EBITDA and Pro Forma adjusted EBITDA for the three and six months ended June 30, 2018 and 2017:

Adjusted Earnings Per Diluted Share

The Company defines adjusted earnings per diluted share as net income adjusted for the after-tax impact of the gain on the issuance of a property easement, the after-tax impact of non-cash write-off of deferred financing fees related to our former credit agreement, the after-tax impact of business development costs, and non-cash foreign currency translation gains or losses, divided by the number of diluted shares used in the earnings per share calculation.

The property easement gain relates to the issuance of an easement on a small portion of owned land at an operating facility which should not hinder our future use. The non-cash write-off of deferred financing fees relates to the write-off of the remaining unamortized fees associated with our former credit agreement which was refinanced in April 2017. Business development costs relate to expenses incurred to evaluate businesses for potential acquisition or costs related to closing and integrating successfully acquired businesses. The foreign currency translation gains or losses excluded from the earnings per diluted share calculation are related to intercompany loans between our Canadian subsidiaries and the U.S. parent which have been established as part of our tax and treasury management strategy. These intercompany loans are payable in Canadian dollars (“CAD”) requiring us to revalue the outstanding loan balance through our consolidated income statement based on the CAD/United States currency movements from period to period.
