WAAS AquaVenture Holdings Limited

As previously disclosed, on December 23, 2019, AquaVenture Holdings Limited (the “Company” or “AquaVenture”) entered into the Agreement and Plan of Merger (the “merger agreement”), among the Culligan International Company (“Culligan”), Amberjack Merger Sub Limited (“Merger Sub”) and the Company providing for the merger of Merger Sub with and into the Company (the “merger”), with the Company surviving the merger as a wholly-owned subsidiary of Culligan. On February 18, 2020, the Company filed with the Securities and Exchange Commission (the “SEC”) a definitive proxy statement (the “Definitive Proxy Statement”) with respect to the special meeting of the Company’s shareholders scheduled to be held on March 16, 2020, in connection with the merger (the “special meeting”).

Litigation Related to the Merger

In connection with the merger with Culligan announced on December 23, 2019, a putative class action lawsuit, Post v. AquaVenture Holdings Ltd., et al., 1:20-cv-174, was filed by purported shareholder Joseph Post against the Company and its directors in the United States District Court for the District of Delaware on February 4, 2020.  On February 12, 2020, in connection with the merger, a lawsuit, Hamilton v. AquaVenture Holdings Ltd., et al., 1:20-cv-01227, was filed as an individual action by purported shareholder Peter Hamilton against the Company and its directors in the United States District Court for the Southern District of New York.  On February 20, 2020, purported shareholder Christopher Jagt filed an individual lawsuit against the Company and its directors in the United States District Court for the Eastern district of New York, captioned Jagt v. AquaVenture Holdings Ltd., et. al.. 1:20-cv-931. The merger actions generally allege that the Preliminary Proxy Statement filed with the SEC on January 27, 2020 or the Definitive Proxy Statement filed on February 18, 2020, as applicable, misrepresents and/or omits certain purportedly material information and assert violations of Sections 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder against all defendants and violations of Section 20(a) of the Exchange Act against the Company’s directors.  The merger actions seek, among other things, an injunction enjoining consummation of the merger, costs of the action, including plaintiff’s attorneys’ fees and experts’ fees, and other relief the Court may deem just and proper.  The defendants believe that the respective allegations asserted against them in the merger actions are without merit and intend to defend against the lawsuits vigorously. Similar cases may be filed in connection with the proposed merger.

While the Company believes the merger actions lack any merit and that the disclosures in the Definitive Proxy Statement comply fully with applicable law, solely in order to avoid the expense and distraction of litigation, the Company has determined voluntarily to supplement the Definitive Proxy Statement with the supplemental disclosures set forth below (the “Supplemental Disclosures”).

Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable law of the Supplemental Disclosures. To the contrary, the Company specifically denies all allegations that any of the Supplemental Disclosures, or any other additional disclosures, were or are required.

The board of directors continues to unanimously recommend that shareholders vote “FOR” the proposal to adopt the merger agreement and “FOR” the other proposal being considered at the special meeting.

Supplemental Disclosures to Definitive Proxy Statement

These Supplemental Disclosures should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety. All page references in the information below are to pages in the Definitive Proxy Statement, and all defined and capitalized terms used below shall have the meanings set forth in the Definitive Proxy Statement. Paragraph references used herein refer to the Definitive Proxy Statement before any additions or deletions resulting from the Supplemental Disclosures. As noted in the Definitive Proxy Statement, the opinions of Citi and UBS were necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, December 23, 2019. Citi and UBS assumed no responsibility for updating or revising their opinions based on events or circumstances that may have occurred after December 23, 2019, and Citi and UBS have not updated or revised its opinion subsequent to such date.

The section of the Definitive Proxy Statement titled “The Merger (Proposal 1)—Opinion of Citigroup Global Markets Inc.” is hereby supplemented by amending the paragraph on page 43 that begins with “Citi conducted a discounted cash flow analysis…” to insert the underlined words in the following sentence:

Citi also calculated estimated terminal values for AquaVenture based on the following selected illustrative ranges of terminal growth rates, selected by Citi based on its professional judgment and experience, and applied to AquaVenture's estimated terminal year unlevered after-tax free cash flow of $60 million (referred to as the "terminal cash flow"): (i) 2.0% to 3.0% in relation to the estimated terminal cash flow contribution from Quench, (ii) 1.0% to 2.0% in relation to the estimated terminal cash flow contribution from Seven Seas Water and (iii) 1.5% to 2.5% in relation to the estimated terminal cash flow expenditure attributable to AquaVenture's Corporate and Other administration function. The estimated terminal values for AquaVenture were then discounted to present values (as of September 30, 2019) and added to the estimated present values of the projected cash flows referred to above in order derive a range of implied firm values for AquaVenture.

Also on page 43, the paragraph that begins with “In calculating the present values…” to insert the underlined words in the following sentence:

From the derived range of implied firm values referenced above, Citi subtracted AquaVenture's reported net debt balance of approximately $206 million (excluding unamortized debt discounts and deferred financing fees) as of September 30, 2019, and divided the result by the number of AquaVenture ordinary shares outstanding on a fully diluted basis of 32.5 million to 33.5 million, calculated using the treasury stock method, based on information provided by management.

The section of the Definitive Proxy Statement titled “The Merger (Proposal 1)—Opinion of UBS Securities LLC” is hereby supplemented by amending the paragraph that begins on page 47 and ends on page 48 that begins with “Unless the context indicates otherwise…” to insert the underlined words in the following sentence:

Unless the context indicates otherwise, (1) Enterprise Values derived from the selected companies analysis described below were calculated using the closing price of the common stock of the selected publicly traded companies in the U.S.-listed water services and related infrastructure industry listed below as of December 20, 2019, (2) transaction values for the target companies derived from the selected transactions analysis described below were calculated based on implied Enterprise Values as of the public announcement date of the relevant transaction, assuming equity values equal to the estimated purchase prices paid for the common equity of the target companies in the selected transactions, or the estimated purchase prices paid for the target business units, as applicable, and (3) net debt for the Company was based on such amount as of September 30, 2019 of approximately $206 million, and was calculated including restricted cash.

Also on page 48, the paragraph that begins with “In addition, unless the context indicates otherwise…” to insert the underlined words in the following sentence:

In addition, unless the context indicates otherwise, (1) per share amounts for the Company's ordinary shares were calculated on a diluted basis, using the treasury stock method, based on shares, options and warrants outstanding as of December 20, 2019, as provided by the management of the Company of approximately 33.0 million, (2) Enterprise Value for the Company was calculated by adjusting for (a) estimated cash payments in connection with acquisitions consummated or expected to be consummated during the fourth quarter of 2019, (b) the present value of estimated principal payments to be collected with respect to long-term receivables from the Company's Peru construction contract and the contracts with the government of St. Maarten (and not otherwise reflected in estimated Adjusted EBITDA) and (c) the net value of estimated usage of net operating loss carryforwards, (3) estimated 2019 data for the Company was based on data pro forma for acquisitions consummated or expected to be consummated during 2019 and (4) estimated data based on internal forecasts and estimates for the Company were based on the base case forecast described more fully below under "—Projected Financial Information.”
