President and CEO Joel Gay remarked, "In addition to posting yet again record-breaking financial results in the quarter, the Company concluded full-scale, private testing of the second generation VorTeq system at an undisclosed facility, and in doing so, executed the most successful examination of the technology to date. While we have in the past refrained from disclosing discreet testing results, due to the swelling anticipation as to the outcome of this process and its materiality to the Company, we feel our shareholders deserve an unfiltered account of what are indisputable proof points as to the product's commercial potential.

The following serves as a synopsis of the testing highlights:

    1. Achieved individual pressure exchanger flow rates of up to 8.5 barrels
       per minute at 9,000 psi clean, which is to say without proppant, all 12
       pressure exchangers achieved rate;
    2. Achieved duration runs of 60 barrels per minute at 9,000 psi clean, again
       without proppant;
    3. Pumped 100,000 lbs of proppant at rates of 62 to 64 barrels per minute,
       proppant concentration of up to 2.4 pounds per gallon added and at
       pressures ranging from 6,800 psi to 7,200 psi; with 87,000 lbs of
       proppant being processed in a continuous, uninterrupted 33-minute run.

Suffice it to say that such results outperformed our expectations as they were achieved during the first and only private testing session which lasted approximately one week. It should be further noted that the second generation VorTeq system is entirely bespoke and distinct from the first generation, which is to say we did not export a single component from Gen-I to Gen-II. That we executed the design, manufacturing and successful testing of a product of this size and complexity in 10 months is an achievement that stands on its own merit. Importantly, we did not witness a single failure mode attributed to the vibrational concerns experienced last year during the testing of the Gen-I system."

Mr. Gay continued, "The technical challenges to executing such an experiment are awesome, specifically simulating a well and having to dissipate up to 20 megawatts of energy contained in a proppant-laden fluid. To simulate the back pressure of a well, we employed a series of progressive chokes downstream of the VorTeq. To this end, while we were able to reach the desired pressure of 9,000 psi without proppant, proppant testing proved more challenging as the very minute sand was introduced to the testing system, the progressive chokes began to rapidly erode - much like the valves in a typical fracking pump - thereby limiting our ability to reach higher pressures. This learning will invariably influence how we design the testing apparatus for future tests up to and including milestone one. In this, success by the year-end remains our objective, yet we will employ the same diligent approach as we have heretofore, keeping a keen eye on the one and only objective: commercialization.

We are hopeful that this fulsome disclosure allows the discourse to progress beyond "does the VorTeq work," to "how and when will it be commercialized?" We have been working flat-out throughout the year to arrive at this point and I am proud of the incredibly talented men and women that constitute our Engineering Team, as well the balance of the organization whose peer group-leading performance has not gone unnoticed by Management."

Revenues

For the third quarter of 2017, the Company generated total revenue of $15.1 million, representing the strongest third quarter top-line performance in Company history, for both the Water and Oil & Gas Segments. Revenue increased by $2.8 million, or 23%, from $12.3 million in the third quarter of 2016. Of the $2.8 million increase in revenue, $2.6 million was attributable to the Water Segment and $0.2 million was attributable to the Oil & Gas Segment.

The Water Segment generated total product revenue of $13.2 million, compared to $10.6 million in the third quarter of 2016. The $2.6 million, or 25%, increase in revenue was due to higher Mega Project ("MPD") and Original Equipment Manufacturer ("OEM") shipments during the third quarter of 2017.

The Oil & Gas Segment generated total revenue of $1.9 million, compared to $1.7 million in the third quarter of 2016. The $0.2 million, or 9%, increase in revenue was due to higher percentage-of-completion ("PoC") revenue recognition associated with the sale of multiple IsoBoost® systems compared to the third quarter of 2016. License and development revenue of $1.25 million was recognized in each of the third quarters of 2017 and 2016.

Gross Margin

For the third quarter of 2017, product gross margin was 69.3%, representing the highest product gross margin in Company history. Product gross margin increased 520 basis points from 64.0% in the third quarter of 2016. This increase was largely driven by manufacturing efficiencies, higher MPD volume and favorable price and product mix in the Water Segment. Including license and development revenue, total gross margin((1) )of 71.8% for the third quarter of 2017 was the highest total gross margin((1)) in Company history. Total gross margin((1)) increased 410 basis points from 67.7% in the third quarter of 2016.

The Water Segment generated product gross margin of 71.1%, representing the highest Water Segment product gross margin in Company history. Water Segment product gross margin increased by 6.0%, compared to 65.5% in the third quarter of 2016. This increase was largely driven by manufacturing efficiencies, higher volume and favorable price and product mix in the third quarter of 2017.

The Oil & Gas Segment generated product gross margin of 28.2%, compared to 29.6% in the third quarter of 2016. This decrease was attributable to PoC revenue recognition costs. Including license and development revenue, the Oil & Gas Segment total gross margin((1)) for the third quarter of 2017 was 76.5%.

Operating Expenses

For the third quarter of 2017, operating expenses were $9.3 million, an increase of $0.3 million from $9.0 million in the third quarter of 2016. The increase in operating expense was primarily due to increased operating expense in the Oil & Gas Segment offset by slightly lower operating expenses in the Water Segment.

The Water Segment operating expenses for the third quarter of 2017 were $2.1 million, a decrease of $0.1 million from $2.2 million in the third quarter of 2016.

The Oil & Gas Segment operating expenses for the third quarter of 2017 were $3.5 million, an increase of $0.4 million from $3.1 million in the third quarter of 2016. This increase was driven by the Company's continued investment in research and development activities.

Finally, corporate operating expenses of $3.7 million for the third quarter of 2017 were on par with the third quarter of 2016.

Bottom Line Summary

To summarize financial performance for the third quarter of 2017, the Company reported a net income of $1.7 million, or $0.03 per share. Comparatively, the Company reported a net loss of $0.6 million, or $(0.01) per share, for the third quarter of 2016.

Cash Flow Highlights

The Company ended the quarter with unrestricted cash of $19.2 million, current and non-current restricted cash of $3.1 million, and short-term investments of $72.2 million, all of which represent a combined total of $94.5 million.

During the nine months ended September 30, 2017, the Company's net cash used by operating activities was ($2.2) million. This includes a net income of $0.7 million and non-cash expenses of $5.6 million, the largest of which were share-based compensation of $3.1 million and depreciation and amortization of $2.7 million. Unfavorably impacting cash flow from operating activities was a reduction in deferred revenue related to the amortization of the VorTeq License Agreement exclusivity fee of ($3.8) million, an increase in estimated earnings in excess of billings of ($2.6) million associated with our PoC revenue recognition, a decrease in accrued liabilities of ($1.7) million and an increase in inventory of ($1.5) million, partially offset by an increase in accounts payable of $1.8 million. Cash used in investing activities was ($39.1) million driven by the net purchases of marketable securities of ($33.6) million and capital expenditures of ($6.8) million, partially offset by a decrease in restricted cash of $1.3 million. Cash used in financing activities was ($0.8) million, driven by common stock repurchases of ($4.3) million and vested restricted stock shares withheld for tax withholdings of ($0.2) million, partially offset by the issuance of common stock related to option exercises of $3.7 million.

Forward-Looking Statements

All forward-looking statements are made as of today, and the Company assumes no obligation to update such statements.

Use of Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures, including total gross margin. 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.
