SAN LEANDRO, CA / ACCESSWIRE / March 5, 2020 / Energy Recovery Inc. (Nasdaq:ERII) ("Energy Recovery," "we," "our," or the "Company"), a leader in pressure energy technology for industrial fluid flows, today announced its financial results for the fourth quarter and fiscal year ended December 31, 2019.

Fiscal Year 2019 Highlights:

• Total product revenue of $72.8 million, an increase of 19% year-over-year
• Total revenue of $86.9 million, an increase of 17% year-over-year
• Product gross margin of 72.1%, an increase of 140 basis points year-over-year
• Income from operations of $10.4 million, an increase of 4% year-over-year
• Net income of $10.9 million, or diluted earnings per share of $0.19, a decrease of $0.21 year-over-year due to a tax benefit of $11.2 million recognized in 2018
• Adjusted net income⁽¹⁾ of $9.9 million, or non-GAAP diluted earnings per share⁽¹⁾ of $0.18, a decrease of $0.02 year-over-year

Chairman and Interim President and Chief Executive Officer Robert Mao remarked, "2019 was a year of new highs for Energy Recovery. In our water business, we achieved our third consecutive year of record-setting revenues, we signed our largest-ever desalination project contract, and we enter 2020 with a high degree of confidence based on closed deals that are expected to ship over the next two years. In addition, we executed our largest to date contract for a thermal to seawater reverse osmosis ("SWRO") desalination replacement project. Thanks to technologies such as our PX® Pressure Exchanger®, SWRO is now much more cost-effective than thermal, encouraging thermal plant owners and operators to replace thermal with SWRO technologies. We estimate this potential TAM to be approximately half a billion dollars at today's prices and are focused on capturing as much of this opportunity as possible over the coming decade."

Mr. Mao continued, "The ability to test continually while iterating design enhancements all in our own facility in Katy, Texas has allowed us to improve the VorTeq's reliability and repeatability. Our ability to process sand in volumes and concentrations used in today's hydraulic fracturing environment gives me confidence that our testing protocol is working. We intend to continue testing the system in preparation for commercialization, which will include live well testing."

Mr. Mao concluded, "While the Company's near-term priorities remain water business growth and VorTeq commercialization, we also made strides in 2019 implementing a structure that will enable a disciplined approach to longer-term growth. I firmly believe Energy Recovery enters this new decade with the right elements in place for continued success."

Revenues

For the year ended December 31, 2019, the Company generated total revenue of $86.9 million, an increase of $12.4 million, or 17%, compared to $74.5 million for the year ended December 31, 2018. This increase was due primarily to Water segment growth.

The Oil & Gas segment generated total revenue of $14.2 million for the year ended December 31, 2019, an increase of $0.2 million, or 1%, compared to $14.0 million for the year ended December 31, 2018, due primarily to an increase in license and development revenue, which is calculated as a percentage of Cost to Total Cost.

Product Gross Margin

For the year ended December 31, 2019, product gross margin was 72.1%, an increase of 140 basis points from 70.7% for the year ended December 31, 2018. This increase was due primarily to higher volume of products sold, favorable product mix, manufacturing equipment upgrades and process improvements.

Operating Expenses

This increase was due primarily to the Company's continued investment in research and development in both the Oil & Gas and Water segment, as well as growth in headcount and personnel-related costs.

Bottom Line Summary

This decrease was due primarily to a discrete tax benefit of $11.2 million related to the reversal of a non-recurring tax benefit for the year ended December 31, 2018, partially offset by $1.0 million related to an increase in prior years U.S. federal research and development credits for the year ended December 31, 2019.

Use of Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures, including total gross margin, adjusted net income and non-GAAP earnings per share. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions, and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. The Company believes these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.

⁽¹⁾ "Total revenue," "Total gross margin," "Adjusted net income" and "Non-GAAP diluted earnings per share" are non-GAAP financial measures. Please refer to the discussion under headings "Use of Non-GAAP Financial Measures" and "Reconciliations of Non-GAAP Financial Measures."
