AquaVenture Holdings Limited Announces Second Quarter 2018 Earnings Results

(Tampa, Fla.) – AquaVenture Holdings Limited (NYSE: WAAS) (“AquaVenture” or the “Company”), a leader in Water-as-a-ServiceTM  (“WAASTM”) solutions, today reported financial results for the quarter ended September 30, 2018.

Highlights

 “I am pleased to report another quarter of double-digit revenue and Adjusted EBITDA growth, in addition to continued success on the execution of our organic and inorganic growth strategies,” said Doug Brown, AquaVenture’s Chairman and Chief Executive Officer. “Our financial results were driven by both organic increases from strong underlying business operations and inorganic additions from completed acquisitions.  In addition, in October we completed an additional tuck-in acquisition in Quench and we entered into a water sale agreement with a new Caribbean water customer. In November, we acquired AUC, a provider of wastewater treatment and water reuse solutions, and we

amended our senior secured credit agreement to accommodate our increased borrowing to fund the AUC acquisition and reduce the cost of our loans.  The collective result of these transactions is the expansion of our Water-as-a-Service solutions into new geographies, for new customers, with a broader array of offered products and services.  We are excited to see the results of our M&A efforts, and continue to actively work on additional deal opportunities, including the previously announced Ghanaian transaction.  We strive to continue this momentum through the remainder of the year and look forward to building on our commitment under Tony’s leadership next year to bring clean, potable water to more people throughout the world.”

Recent Developments

Quench Transactions.  On October 1, 2018, Quench acquired substantially all the assets of Quality Water Services, a point-of-use water filtration company based in Seattle, Washington. This transaction added approximately 1,200 rental units to Quench’s installed asset base and increased customer density in the important Seattle market, a top-12 U.S. Metro area.

On October 1, 2018, Quench sold substantially all of the assets of its Atlas High Purity Solutions unit.  The aggregate sale price, subject to working capital adjustments, was approximately $3.0 million, including $2.7 million in cash and a receivable from the buyer of $0.3 million, and the assumption of certain liabilities. Atlas High Purity Solutions was acquired in connection with the Atlas Watersystems transaction in June 2014.

Seven Seas Water Transactions. On October 4, 2018, Seven Seas Water entered into an agreement with the Water Corporation of Anguilla, the public water utility of Anguilla, to supply potable water under a 10-year contract. Water production, which will commence immediately, will be at an initial capacity of 500,000 gallons per day and expand to 750,000 gallons per day within the next several months.

Acquisition of AUC. On November 1, 2018, AquaVenture Holdings completed the acquisition of all of the issued and outstanding membership interests of AUC Acquisitions Holdings (“AUC”) for an aggregate purchase price of approximately $130.0 million, including $128.0 million cash and 121,956 AquaVenture ordinary shares, subject to adjustment as provided in the purchase agreement. The acquisition expands the Company’s WAAS offerings in the wastewater treatment and water reuse businesses and broadens the Company’s portfolio in the United States.

Corporate Debt Financing. On November 1, 2018, AquaVenture amended its senior secured credit agreement to increase its borrowings to $260.0 million, a net increase of $110.0 million, and reduce the interest rate for the existing $150.0 million borrowings by 50 basis points on both the variable and fixed portions.  As a result, $145.0 million of borrowings bear interest at a variable rate of LIBOR plus 5.5% with a LIBOR floor of 1.0% and the remaining $115.0 million of borrowings bear interest at a weighted average fixed rate of 8.0%. All other terms of the amended credit agreement remain substantially unchanged.  Proceeds from the incremental borrowing were used to fund the acquisition of AUC.

Third quarter 2018 Segment Results

Seven Seas Water

Seven Seas Water revenues of $15.6 million for the third quarter of 2018 increased 10.8% from $14.1 million in the same period of 2017. This organic increase was driven by (i) $0.5 million higher revenues in our USVI operations, primarily due to increases in production volumes in the current quarter compared to the same period of 2017, (ii) a $0.4 million increase in revenues in our St. Maarten operations due to lower revenues in the prior year period resulting from hurricanes Irma and Maria, and (iii) higher revenues in our Trinidad and BVI plants primarily driven by increases in the water rate compared to the prior year period. These increases were offset in part by a $0.1 million decrease in financing revenue as a result of the continued amortization of the long-term receivables.

Seven Seas Water gross margin of 56.6% for the third quarter of 2018 decreased 100 basis points from 57.6% in the same period of 2017, primarily related to a decline in our bulk water gross margin as well as a decrease in financing revenue as a result of the continued amortization of the long-term receivables. Bulk water gross margin of 53.7% decreased 20 basis points compared to the prior year period, primarily due to better-than-expected performance in the prior year period in our Peru operations (including the timing of certain repairs and maintenance activities), partially offset by improved margins in BVI driven by higher revenues without a commensurate increase in costs and in St. Maarten primarily due to the aforementioned impact of the hurricanes in the prior year period.

Seven Seas Water SG&A for the third quarter of 2018 increased $0.3 million to $7.6 million compared to the prior year period, primarily due to higher share-based compensation expense due to new equity awards granted in the first quarter of 2018.  

Net income for our Seven Seas Water segment was $0.4 million for the three months ended September 30, 2018 compared to a net loss of $2.6 million in the same period of 2017. Included in the net income for the three months ended September 30, 2018 was a non-cash income tax benefit of $3.1 million related to the release of a deferred tax

asset valuation allowance.  Adjusted EBITDA of $7.7 million for the third quarter of 2018 increased 6.7% over $7.2 million in the prior year period. Adjusted EBITDA Margin decreased 190 basis points to 49.2% in the third quarter of 2018 from 51.1% in the same period of 2017. Adjusted EBITDA plus principal collected on the Peru construction contract was $8.9 million in the third quarter of 2018, an increase of 7.0% over $8.3 million in the prior year period. 

For the nine months ended September 30, 2018, Seven Seas Water revenues were $45.7 million, an increase of 6.3% over revenues of $43.0 million in the same period of 2017.  Gross margin increased 370 basis points to 56.2% from 52.5% in the prior year period. Total SG&A expenses for the nine months ended September 30, 2018 increased $1.6 million to $22.4 million from $20.8 million in the same period of 2017.  Net loss for the nine months ended September 30, 2018 was $3.6 million compared to a net loss of $7.3 million for the same period of 2017. Adjusted EBITDA was $22.2 million for the nine months ended September 30, 2018, an increase of 14.3% over $19.4 million in the same period of 2017. Adjusted EBITDA Margin increased 340 basis points to 48.6% from 45.2% in the prior year period. Adjusted EBITDA plus principal collected on the Peru construction contract was $25.8 million, a 13.5% increase over $22.8 million in the same period of 2017.

Quench

Quench revenues of $21.2 million for the third quarter of 2018 increased 35.2% from $15.7 million in the same period of 2017.  Rental revenues increased $2.8 million, or 21.1%, compared to the prior year period, including 6.8% organic growth from additional units placed under new leases in excess of unit attrition. Other revenues increased $2.7 million compared to the same period of 2017, driven by the inclusion of dealer equipment sales resulting from our September 2017 Wellsys acquisition, as well as higher direct customer equipment sales and coffee sales compared to the prior year period.

Quench gross margin for the third quarter of 2018 decreased 140 basis points to 51.0% from 52.4% for the same period of 2017, primarily due to the inclusion of lower-margin equipment revenue from our Wellsys business that was acquired in September 2017, which is recorded in other revenues. Partially offsetting this was a 150 basis points increase in rental gross margin, primarily due to a higher allocation of service personnel costs to capitalizable installation activities compared to the prior year period.

Quench SG&A for the third quarter of 2018 increased $2.4 million to $12.2 million compared to the same period of 2017.  The increase was driven by $0.7 million higher compensation and benefits expense primarily driven by increased headcount from the inclusion of staff added from certain acquisitions and additional resources to support our inorganic growth strategy, $0.6 million higher amortization expense primarily related to intangible assets from recent acquisitions, $0.3 million increase in loss on disposal of assets and $0.1 million higher share-based compensation expense due to new equity awards granted in the first quarter of 2018.

Quench had a net loss of $2.3 million for the third quarter of 2018 compared to a net loss of $3.0 million in the prior year period. Adjusted EBITDA of $5.7 million for the third quarter of 2018 increased 47.7% over $3.9 million in the same period of 2017. Adjusted EBITDA Margin increased 230 basis points to 27.0% in the third quarter of 2018 from 24.7% in the prior year period.

For the nine months ended September 30, 2018, Quench reported total revenue of $58.1 million, a 27.4% increase compared to the prior year period revenue of $45.6 million. Gross margin decreased 320 basis points to 50.3% compared to 53.5% in the same period of 2017. Total SG&A expenses for the nine months ended September 30, 2018 increased $5.1 million to $34.1 million.  Net loss for nine months ended September 30, 2018 was $7.2 million, compared to a net loss of $8.2 million in the same period of 2017. Adjusted EBITDA was $14.5 million for the nine months ended September 30, 2018, a 22.5% increase over $11.8 million in the same period of 2017.  Adjusted EBITDA Margin decreased 100 basis points to 24.9% compared to 25.9% in the prior year period.

Corporate and Other

Corporate and Other SG&A for the third quarter of 2018 decreased to $1.0 million from $1.3 million in the same period of 2017.  For the nine months ended September 30, 2018, SG&A was $3.2 million compared to $3.3 million in the prior year period.     

2018 Outlook

For the full year 2018 outlook, the Company has incorporated the anticipated impacts of the acquisitions completed since the beginning of 2018, including the most recently announced acquisition of AUC.  As a result, the Company increased its full year 2018 outlook and now expects to achieve the following results:

The impact of the binding agreement with Abengoa Water to purchase a majority interest in a desalination plant in Accra, Ghana has not been included in the 2018 outlook due to the pending conditions precedent.

The above statements are based on current expectations and supersede previously provided guidance. These statements are forward-looking, and actual results may differ materially. We do not provide GAAP financial measures on a forward-looking basis because we are unable to predict with reasonable certainty the ultimate outcome of unusual gains and losses, acquisition-related expenses and purchase accounting fair value adjustments, among other factors, without unreasonable effort. These items are uncertain, depend on various factors, and could be material to our results computed in accordance with GAAP.

UNAUDITED KEY METRICS

(IN THOUSANDS)

Management uses key metrics for internal reporting and forecasting purposes, when publicly providing its business outlook, to evaluate the Company’s performance and to evaluate and compensate the Company’s executives.  The Company has provided these metrics because it understands that some investors and financial analysts find this information helpful in analyzing the Company’s financial results and comparing the Company’s financial performance to that of its peer companies and competitors.

NON-GAAP FINANCIAL MEASURES

Among the key metrics are non-GAAP financial measures.  The Company has provided non-GAAP financial measures in addition to GAAP financial results because it believes that these non-GAAP financial measures provide useful information to certain investors and financial analysts for comparisons across accounting periods not influenced by certain non-cash items that are not used by management when evaluating the Company’s historical and prospective financial performance.

Adjusted EBITDA

Adjusted EBITDA, a non‑GAAP financial measure, is defined as earnings (loss) before net interest expense, income taxes, depreciation and amortization as well as adjusting for the following items: share‑based compensation expense; gain or loss on disposal of assets; acquisition‑related expenses, including professional fees, purchase consideration recorded as compensation expense for acquired employees, and other expenses related to acquisitions; goodwill impairment charges; changes in deferred revenue related to our bulk water business; ERP system implementation charges for a SaaS solution and certain adjustments recorded in connection with purchase accounting for acquisitions.  Adjusted EBITDA should not be considered a measure of financial performance under GAAP. Management believes that the use of Adjusted EBITDA, which is used by management as a key metric to assess performance, provides consistency and comparability with our past financial performance, and facilitates period‑to‑period comparisons of operations. Management believes that it is useful to exclude certain charges, such as depreciation and amortization, and non‑core operational charges, from Adjusted EBITDA because (1) the amount of such expenses in any specific period may not directly correlate to the underlying performance of our business operations and (2) such expenses can vary significantly between periods.

Adjusted EBITDA Margin

Adjusted EBITDA Margin, a non-GAAP financial measure, is defined as Adjusted EBITDA as a percentage of revenue.

A reconciliation of our GAAP net loss to Adjusted EBITDA, for the periods presented is shown below:
