Operating results for the three and six month periods ended ~~March 31,~~June 30, 2019 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2019.

The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission ("SEC") and do not include all information and footnotes required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2018 and notes thereto included in our 2018 Annual Report on Form 10-K, which we filed with the SEC on March 4, 2019.

Segments

Our General Partner has concluded that we operate in one business segment.

Significant Accounting Policies

We have added policies for the recording of leases in conjunction with the adoption of the new lease standard discussed in our "Leases" and "New Accounting Pronouncements" sections below. Other than the additional lease policies described herein, there have been no significant changes in our accounting policies or the application of these policies.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material.

Impairments and Other Charges

During the three month period ending June 30, 2019, we recorded impairments of $2.3 million on certain units of our low-horsepower compression fleet, reflecting our decision to dispose of these units upon management's determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. A recoverability analysis was performed on the remaining low-horsepower fleet and we concluded that the remaining fleet was recoverable from estimated future cash flows.

Foreign Currencies

Accumulated other comprehensive income (loss) is included in partners’ capital in the accompanying consolidated balance sheets and consists of the cumulative currency translation adjustments associated with our international operations. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled ~~$(1.0)~~$(0.04) million and ~~$(1.1)~~$(1.0) million during the three and six month periods ended ~~March 31,~~June 30, 2019, respectively, and ~~March 31,~~$0.5 million and $(0.6) million during the three and six month periods ended June 30, 2018, respectively.

Leases

As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term.

All of our long-term leases are operating leases and are included in operating lease right-of-use assets, accrued liabilities and other, and operating lease liabilities in our consolidated balance sheet as of ~~March 31,~~June 30, 2019. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term, if it is reasonably certain that we would exercise the option.

As an accounting policy election, we do not include short-term leases on our balance sheet. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or selling, general, and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred.

As allowed by U.S. GAAP, we do not separate nonlease components from the associated lease component for our compression services contracts and instead account for those components as a single component based on the accounting treatment of the predominant component. In our evaluation of whether Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842 "Leases" or ASC 606 "Revenue from Contracts with Customers" is applicable to the combined component based on the predominant component, we determined the services nonlease component is predominant, resulting in the ongoing recognition of our compression services contracts following ASC 606.

Our operating leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present.

Earnings Per Common Unit

Our computations of earnings per common unit are based on the weighted average number of common units outstanding during the applicable period. Basic earnings per common unit are determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our General Partner (including any distributions to our General Partner on its incentive distribution rights) by the weighted average number of outstanding common units during the period.

When computing earnings per common unit under the two class method in periods when distributions are greater than earnings, the amount of the distribution is deducted from net income (loss) and the excess of distributions over earnings is allocated between the General Partner and common units based on how our Partnership Agreement allocates net losses.

Diluted earnings per common unit are computed using the treasury stock method, which considers the potential future issuance of limited partner common units. Unvested phantom units are not included in basic earnings per common unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per common unit. For the three and six month periods ended ~~March 31,~~June 30, 2019 and ~~March 31,~~June 30, 2018, all unvested phantom units were excluded from the calculation of diluted common units because the impact was anti-dilutive. Diluted earnings per common unit are computed using the "if converted" method, whereby the amount of net income (loss) and the number of common units issuable are each adjusted as if the Preferred Units, discussed in Note D - "Series A Convertible Preferred Units", had been converted as of the beginning of the period presented. The number of common units that may be issued upon future conversion of the Preferred Units is excluded from the calculation of diluted common units for the three and six month periods ended ~~March 31,~~June 30, 2019 and 2018 as the impact would be anti-dilutive.

Distributions

On January 22, 2019, our General Partner declared a cash distribution attributable to the quarter ended December 31, 2018 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on January 22, 2019, our General Partner approved the paid in kind distribution of 85,565 Preferred Units attributable to the quarter ended December 31, 2018 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on February 14, 2019, to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on February 1, 2019.

On April 18, 2019, our General Partner declared a cash distribution attributable to the quarter ended March 31, 2019 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on April 18, 2019, our General Partner approved the paid in kind distribution of 59,953 Preferred Units attributable to the quarter ended March 31, 2019 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on May 15, 2019, to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on May 1, 2019.

New Accounting Pronouncements

Standards adopted in 2019

In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities in the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, ASC 842 will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted the standard effective January 1, 2019. The standard had a material impact on our consolidated balance sheet, specifically, the reporting of our operating leases.

We chose to transition using a modified retrospective approach which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Comparative information is reported under the accounting standards that were in effect for those periods. In addition, upon transition, we elected the package of practical expedients, which allows us to continue to apply historical lease classifications to existing contracts. Upon adoption, we recognized $8.3 million in operating right-of-use assets, $3.5 million in accrued liabilities, and ~~$4.8~~$4.8 million in operating lease liabilities. Refer to Note J - “Leases” for further information on our leases.

In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220)" that gives entities the option to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This iswas effective for us on January 1, 2019,

however, as we do not have associated tax effects in accumulated other comprehensive income, there was no impact.

In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. We adopted this ASU during the three months ended March 31, 2019, with no material impact to our consolidated financial statements.

Standards not yet adopted

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. ASU 2016-13 has an effective date of the first quarter of fiscal 2020. We are currently assessing the potential effects of these changes to our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 clarifies the accounting for implementation costs in cloud computing arrangements. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.

NOTE B – INVENTORIES

There was no balance outstanding under the Credit Agreement as of ~~March 31,~~June 30, 2019. As of ~~March 31,~~June 30, 2019, and subject to compliance with the covenants, borrowing base, and other provisions of the agreements that may limit borrowings under the Credit Agreement, we had availability of ~~$18.4~~$22.2 million.

On June 26, 2019, we entered into an amendment of the Credit Agreement that, among other things, revised and increased the borrowing base, including adding the value of certain inventory in the determination of the borrowing base.

Our credit and senior note agreements contain certain affirmative and negative covenants, including covenants that restrict the ability to pay dividends or other restricted payments. We are in compliance with all covenants of our ~~respective~~ credit and senior note agreements as of ~~March 31,~~June 30, 2019.

Refer to Note F - "Related Party Transactions," for a discussion of our long-term affiliate payable to TETRA.

NOTE D – SERIES A CONVERTIBLE PREFERRED UNITS

During 2016, we issued an aggregate of 6,999,126 Preferred Units for a cash purchase price of $11.43 per Preferred Unit (the “Issue Price”). One of the purchasers was TETRA, which purchased 874,891 of the Preferred Units at the aggregate Issue Price of $10.0 million.

Unless otherwise redeemed for cash, a ratable portion of the Preferred Units has been, and may be, converted into common units on the eighth day of each month over a period of thirty months that began in March 2017 and will end in August 2019 (each, a “Conversion Date”). Based on the number of Preferred Units outstanding as of ~~March 31,~~June 30, 2019, the maximum aggregate number of common units that could be required to be issued pursuant to the conversion provisions of the Preferred Units is approximately ~~10.2~~4.3 million common units; however, the Partnership may, at its option, pay cash, or a combination of cash and common units, to the holders of Preferred Units instead of issuing common units on any Conversion Date, subject to certain restrictions as described in the Second Amended and Restated Partnership Agreement and the Credit Agreement. Beginning with the January 2019 Conversion Date, we have elected to redeem the remaining Preferred Units for cash, resulting in ~~783,046~~1,870,681 Preferred Units being redeemed during the ~~three~~six months ended ~~March 31,~~June 30, 2019 for ~~$9.4~~$22.5 million, which includes

approximately ~~$0.4~~$1.1 million of redemption premium that was paid and charged to other (income) expense, net in the accompanying consolidated statements of operations. The total number of Preferred Units outstanding as of ~~March 31,~~June 30, 2019 was ~~1,779,417.~~751,736. The last redemption of the remaining 375,868 Preferred Units, along with a final cash payment made in lieu of paid in kind units for the quarter ended June 30, 2019, for an aggregate cash payment of $5.0 million, is scheduled to occur on August 8, 2019.

The fair value of the Preferred Units is classified as a long-term liability on our consolidated balance sheets. The fair value of the Preferred Units as of ~~March 31,~~June 30, 2019 was ~~$20.9~~$9.0 million. During the three month periods ended March 31, 2019 and March 31, 2018, changes in the fair value resulted in $1.3 million and $1.6 million being charged to earnings, respectively, in the accompanying consolidated statements of operations.

Based on the conversion provisions of the Preferred Units, and using the Conversion Price calculated as of ~~March 31,~~June 30, 2019, the theoretical number of common units that would be issued if all of the outstanding Preferred Units were converted on ~~March 31,~~June 30, 2019 on the

same basis as the monthly conversions would be approximately ~~7.4~~2.7 million common units, with an aggregate market value of ~~$21.0~~$9.7 million. A $1 decrease in the Conversion Price would result in the issuance of approximately ~~2.8~~1.3 million additional common units pursuant to these conversion provisions.

NOTE E – FAIR VALUE MEASUREMENTS

Financial Instruments

Preferred Units

The Preferred Units are valued using a lattice modeling technique that, among a number of lattice structures, includes significant unobservable items (a Level 3 fair value measurement). These unobservable items include (i) the volatility of the trading price of our common units compared to a volatility analysis of equity prices of comparable peer companies, (ii) a yield analysis that utilizes market information related to the debt yields of comparable peer companies, and (iii) a future conversion price analysis. During the three month periods ended March 31, 2019 and March 31, 2018, the changes in the fair value of the Preferred Units resulted in $1.3 million and $1.6 million being charged to earnings, respectively, in the consolidated statements of operations.

Derivative Contracts

As of ~~March 31,~~June 30, 2019, we had the following foreign currency derivative contract outstanding relating to a portion of our foreign operations:

Under a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries, we may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as economic hedges of the cash flow of our currency exchange risk exposure, they will not be formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period.

The fair values of our foreign currency derivative instruments are based on quoted market values (a Level 2 fair value measurement). The fair values of our foreign currency derivative instruments as of ~~March 31,~~June 30, 2019 and December 31, 2018, are as follows:


Foreign currency derivative instruments	Balance Sheet	Fair Value at						Balance Sheet	Fair Value at

None of ~~the~~our foreign currency derivative contracts contains credit risk related contingent features that would require us to post assets or collateral for contracts that are classified as liabilities. During the three and six month periods ended ~~March 31,~~June 30, 2019 we recognized $0.2 million and ~~March 31,~~$0.3 million, respectively, of net (gains) losses associated with our foreign currency derivative program, and such amounts are included in other (income) expense, net, in the accompanying consolidated statement of operations. During the three and six month periods ended June 30, 2018, we recognized ~~$0.1~~$0.7 million and ~~$0.5~~$0.2 million, respectively, of net (gains) losses associated with our foreign currency derivative program, and such amounts are included in other (income) expense, net, in the accompanying consolidated statement of operations.

We based the fair values of our 7.25% Senior Notes and our 7.50% Senior Secured Notes as of ~~March 31,~~June 30, 2019 on recent trades for these notes.

NOTE F – RELATED PARTY TRANSACTIONS

Omnibus Agreement

Under the terms of the Omnibus Agreement, our General Partner provides all personnel and services reasonably necessary to manage our operations and conduct our business (other than in Mexico, Canada, and Argentina), and certain of TETRA’s Latin American-based subsidiaries provide personnel and services necessary for the conduct of certain of our Latin American-based businesses. In addition, under the Omnibus Agreement, TETRA provides certain corporate and general and administrative services as requested by our General Partner, including,

without limitation, legal, accounting and financial reporting, treasury, insurance administration, claims processing and risk management, health, safety and environmental, information technology, human resources, credit, payroll, internal audit, and tax services. Pursuant to the Omnibus Agreement, we reimburse our General Partner and TETRA for services they provide to us.

TETRA and General Partner Ownership

As of ~~March 31,~~June 30, 2019, TETRA's ownership interest in us was approximately 34% of the outstanding common units, 12.6% of the outstanding Preferred Units, and an approximately 1%1.4% general partner interest, through which it holds incentive distribution rights. ~~As Preferred Units are converted to common units, TETRA's percentage ownership of the common units will decrease.~~

Other Sources of Financing

In February 2019, we entered into a transaction with TETRA whereby TETRA has agreed to fund the construction of and purchase up to $15.0 million of new ~~compression~~compressor services equipment and lease it to us in exchange for a monthly rental fee. As of ~~March 31,~~June 30, 2019, pursuant to this arrangement, ~~$2.4~~$11.1 million has been ~~advanced to us~~funded by TETRA for the construction of new ~~compression~~compressor equipment and is included in long-term affiliate payable in our consolidated balance sheet.

NOTE G – INCOME TAXES

As a partnership, we are generally not subject to income taxes at the entity level because our income is included in the tax returns of our partners. Our operations are treated as a partnership for federal tax purposes with each partner being separately taxed on its share of taxable income. However, a portion of our business is conducted through taxable U.S. corporate subsidiaries. Accordingly, a U.S. federal and state income tax provision has been reflected in the accompanying statements of operations. Certain of our operations are located outside of the U.S., and the Partnership, through its foreign subsidiaries, is responsible for income taxes in these countries.

Our effective tax rate for the ~~three~~six month period ended ~~March 31,~~June 30, 2019, was negative ~~54.1%~~31.3% primarily attributable to taxes in certain foreign jurisdictions and Texas gross margin taxes combined with losses generated in entities for which no related tax benefit has been recorded. In addition, the application of ASC 740-270 "Income Taxes - Interim Reporting," resulted in an accrual of current income taxes for the ~~three~~six month period ended ~~March 31,~~June 30, 2019 equal to approximately the full year estimate. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.

NOTE H – COMMITMENTS AND CONTINGENCIES

From time to time, we are involved in litigation relating to claims arising out of our operations in the normal course of business. While the outcome of any lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

NOTE I – REVENUE ~~RECOGNITION~~FROM CONTRACTS WITH CUSTOMERS

Performance Obligations. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers.

Compression and related services. For compression services revenues recognized over time, our customer contracts typically provide agreed upon monthly service rates and we recognize service revenue based upon the number of days that services have been performed. We receive cash equal to the invoice price for most product sales and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. With the exception of the initial terms of our compression services contracts of our medium- and high-horsepower compressor packages, our customer contracts are generally for terms of one year or less. Since the period between when we deliver products or services and when the customer pays for such products or services ~~are~~is not expected to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts.

Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation. For example, consideration received from customers during the fabrication of new compressor packages is typically deferred until control of the compressor package is transferred to our customer. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated

service period. As of ~~March 31,~~June 30, 2019, we had ~~$24.6~~$45.3 million of remaining performance obligations related to our compression service contracts. As a practical expedient, this amount does not reflect revenue for compression service contracts whose original expected duration is less than 12 months and does not consider the effects of the time value of money. The remaining performance obligations, and associated revenues, will be recognized through 2023 as follows:

Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We recognize the cost for freight and shipping costs when control over our products (i.e. delivery) has transferred to the customer as part of cost of product sales.

Equipment Sales & Aftermarket Services. Equipment sales and most aftermarket service revenues are recognized at a point in time when we transfer control of our products and complete the delivery of services to our customers.

Use of Estimates. Our revenues do not include material amounts of variable consideration, as our revenues typically do not require significant estimates or judgments. The transaction price on a majority of our arrangements are fixed and product returns are immaterial. Additionally, our arrangements typically do not include multiple performance obligations that require estimates of the stand-alone purchase price for each performance obligation. Revenue on certain aftermarket service arrangements that include time as a component of the transaction price is not recognized until the performance obligation is complete.

Contract Assets and Liabilities. ~~Any~~We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Our contract asset balances, primarily associated with these documentation requirements, were $8.0 million and $5.9 million as of June 30, 2019 and December 31, 2018, respectively. Contract assets, along with billed ~~and unbilled~~trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets.

We classify contract liabilities as Unearned Income in our consolidated balance sheets. Such unearned income typically results from advance payments received on orders for new compressor equipment prior to the time such equipment is completed and transferred to the customer in accordance with the customer contract.

~~There were no contract assets as of~~ ~~December 31, 2018~~ ~~and~~ ~~March 31, 2019~~. The following table reflects ~~the~~ changes in our contract liabilities ~~during~~for the ~~three month period ended~~ ~~March 31, 2019~~:periods indicated:

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, ~~contract liabilities increased due to unearned income for consideration received on new compressor equipment being fabricated. During the~~ ~~three~~ ~~months ended March 31, 2019, $24.6 million of unearned income was~~we recognized asin product sales revenue ~~primarily associated with deliveries~~$18.7 million from unearned income that was deferred as of ~~new compression equipment.~~December 31, 2018. During the six months ended June 30, 2018, we recognized in product sales revenue of $13.8 million from unearned income that was deferred as of our adoption of ASC 606 on January 1, 2018.

Contract Costs. As of ~~March 31,~~June 30, 2019, ~~and March 31, 2018,~~ contract costs are immaterial.

Disaggregation of Revenue. We disaggregate revenue from contracts with customers by geography based on the following table.

NOTE J – LEASES

We have operating leases for some of our office space, warehouse space, operating locations, and machinery and equipment. Our leases have remaining lease terms ranging from 1 to 10 years. Some of our leases have options to extend for various periods, while some have termination options with prior notice of generally 30 days or six months. Our leases generally require us to pay all maintenance and insurance costs. We do not have leases that have not yet commenced that create significant rights and obligations. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Lease costs are included in either cost of revenues or selling, general, and administrative expense depending on the use of the underlying asset. Components of lease expense (inclusive of lease expense for leases not included on our consolidated balance sheet based on our accounting policy election to exclude leases with a term of 12 months or less), were ~~$1.8~~$1.9 million and $3.7 million for the three ~~months~~and six month periods ended ~~March 31,~~June 30, 2019, respectively, of which, ~~$0.4~~$0.5 million ~~was~~and $1.0 million respectively, related to short-term leases. Variable rent expense was not material.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and accompanying notes included in this Quarterly Report. In addition, the following discussion and analysis also should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on March 4, 2019 ("2018 Annual Report"). This discussion includes forward-looking statements that involve certain risks and uncertainties.

Business Overview

~~Growth~~The construction of infrastructure to alleviate current takeaway capacity constraints that are limiting production and new drilling in the Permian Basin has continued to contribute to increased demand for ~~our compression services~~compressor equipment and ~~equipment~~services. This growth in demand continues to drive increases in our compression services and equipment sales revenues, through increased activity and ~~gross margin. Compression and related services revenues increased $9.3 million during the current quarter compared to the prior year quarter.~~customer contract pricing. Our ~~first~~second quarter utilization rates in our overall compression service fleet increased to ~~87.2%~~89.1% as of ~~March 31,~~June 30, 2019 ~~from 86.6% as of December 31, 2018~~ and ~~84.2% as of March 31, 2018. For~~for our high-horsepower class, the utilization rate increased to ~~95.6%~~97.1% at ~~March 31, 2019 from 95.0% as~~June 30, 2019. This represents the highest overall utilization rate since the acquisition of ~~December 31, 2018 and 92.9% as~~Compressor Systems, Inc. ("CSI") in 2014. Our high-horsepower (over 1,000 horsepower) compression fleet now represents 47.8% of ~~March 31, 2018.~~total horsepower in our fleet. In addition to increasing our utilization rates, the increase in demand has provided us the ability to benefit from improved contract pricing on ~~our compression~~newly deployed equipment as well as increased pricing on previously deployed equipment when contracts are renewed. As overall industry utilization of high-horsepower compressor equipment approaches maximum levels, customer demand for aftermarket services and ~~the opportunity to gain efficiencies on repeat orders~~parts has increased for maintenance and overhaul of ~~new equipment sales. Demand was consistent for our aftermarket services when compared to the prior year quarter, as customers spent maintenance capital to deploy~~customer-owned compression ~~units that were previously idle.~~

New equipment sales revenues increased $9.1 million during the current quarter compared to the prior year quarter. The construction of infrastructure to alleviate current takeaway capacity constraints that is limiting production and new drilling in the Permian Basis has resulted in increased demand for equipment.fleets. Our new equipment sales backlog was ~~$93.9~~$59.7 million as of ~~March 31, 2019. The decrease in our backlog from~~June 30, 2019 and $105.2 million as of December 31, ~~2018 of $105.2 million~~2018. The decrease is the result of converting backlog into revenue for completed orders during the ~~current~~first half of the year ~~quarter.~~in excess of new orders received during the period. New equipment sales orders generally take less than twelve months to build and deliver. We expect all of our current backlog to be recognized in revenue during fiscal year 2019. Our results of operations for the three month period ending March 31, 2019 reflect margins on equipment sales contracts entered into in prior periods. Our equipment sales orders are largely prepaid by the customer through progressive billings, which allows us to fabricate new compression units using our customers' funding.

~~Our~~In light of the current high demand for compression services, our focus remains on our ability to appropriately expand and maintain our compression equipment fleet in order to serve our customers. ~~During the first three months of 2019,~~As we ~~spent $17.6 million (inclusive of $2.4 million paid by TETRA as discussed below),~~seek to ~~expand primarily~~minimize long-term debt borrowings under our ~~high-horsepower class of compression equipment,~~Credit Agreement and ~~$5.7 million to maintain our compression fleet. In order to meet current and future demand,~~senior notes, we ~~continue to evaluate options to fund the expansion of our compression and related services. Through currently~~are supplementing available cash and operating cash flows ~~we have sufficient liquidity to allow us to fund additional capital expenditures during the remainder~~with other forms of ~~2019 without having to access available borrowings under~~financing, including our Credit Agreement and without having to access the debt and equity markets, as current conditions in the debt and equity markets have increased the difficulty of obtaining attractive financing. Pursuant to agreements executed in February 2019 agreement with TETRA, ~~has agreed to purchase up to $15.0 million of new compression services equipment and lease it to us in exchange~~which provided funding for ~~a monthly rental fee. In addition to these anticipated additional growth capital expenditures, we also seek to grow through targeted acquisition opportunities, with expected funding through~~ the issuance of additional debt and equity securities, to the extent possible and financially prudent. Our Credit Agreement provides up to $50.0 million of working capital, subject to borrowing base limitations, to fund the working capital needsexpansion of our ~~business.~~compression equipment fleet. As a result of ~~increased borrowings~~this agreement, beginning in July 2019, approximately 20,700 horsepower of additional compressor equipment will be deployed, and we will have the right to purchase the equipment from TETRA at ~~a higher rate~~any time over the five year lease term. These anticipated 2019 growth plans are expected to ~~finance the growth of~~expand our ~~medium- and high- horsepower~~high-horsepower compression fleet ~~interest expense~~by approximately 98,000 horsepower, focused on key customers as they look to their 2020 compression needs. However, if additional desired capital expenditures exceed available sources, and other financing sources are not available, we will not have the ability to expand our compression services fleet to meet the increased ~~during the current quarter compared~~demand. We continue to ~~the prior year quarter.~~review other financing options available to fund our growth.

Beginning with the distribution made during the first quarter of 2019, and consistent with our December 20, 2018 announcement, given the decline in our common unit price, we reduced our common unit distributions from $0.75 per unit per year (or $0.1875 per quarter) to $0.04 per unit per year (or $0.01 per quarter). During the first quarter of 2019, we began to redeem the remaining Series A Convertible Preferred Units (the "Preferred Units") for cash and avoid the further dilution to our common unitholders that would occur if the Preferred Units were converted into common units.

How We Evaluate Our Operations

Operating Expenses. We use operating expenses as a performance measure for our business. We track our operating expenses using month-to-month, quarter-to-quarter, year-to-date, and year-to-year comparisons and as compared to budget. This analysis is useful in identifying adverse cost trends and allows us to investigate the cause of these trends and implement remedial measures if possible. The most significant portions of our operating expenses are for our field labor, repair and maintenance of our equipment, and for ~~the~~ fuel and other supplies consumed while providing our services. ~~Other~~The costs of other materials consumed while performing our services, ad valorem taxes, other labor costs, truck maintenance, rent on storage facilities, and insurance expenses comprise the significant remainder of our operating expenses. Our operating expenses generally fluctuate with our level of activity.

Our labor costs consist primarily of wages and benefits for our field and fabrication personnel, as well as expenses related to their training and safety. Additional information regarding our operating expenses for the three and six month period ended ~~March 31,~~June 30, 2019, is provided within the Results of Operations sections below.

Adjusted EBITDA. We view Adjusted EBITDA as one of our primary management tools, and we track it on a monthly basis, both in dollars and as a percentage of revenues (typically compared to the prior month, prior year

period, and to budget). We define Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, and before certain non-cash charges, consisting of impairments, ~~bad debt expense attributable to bankruptcy of customer,~~ equity compensation, non-cash costs of compressors sold, fair value adjustments of our Preferred Units, ~~gain on extinguishment of debt, administrative expenses under the Omnibus Agreement paid in equity using common units,~~ write-off of unamortized financing costs, and excluding ~~acquisition and transaction costs,~~ Series A Preferred redemption premiums, and severance. Adjusted EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements, including investors, to:

assess our ability to generate available cash sufficient to make distributions to our common unitholders and general partner;

evaluate the financial performance of our assets without regard to financing methods, capital structure, or historical cost basis;

measure operating performance and return on capital as compared to our competitors; and

determine our ability to ~~incur and~~ service debt and fund capital expenditures.

The following table reconciles net income (loss) to Adjusted EBITDA for the periods indicated:

Free Cash Flow. We define Free Cash Flow as cash from operations less capital expenditures, net of sales proceeds. Management primarily uses this metric to assess our ability to retire debt, evaluate our capacity to further

invest and grow, and measure our performance as compared to our peers. The following table reconciles cash provided by operations, net, to Free Cash Flow for the periods indicated:


	Three Months Ended March 31,						Three Months Ended June 30,						Six Months Ended June 30,
	2019			2018			2019			2018			2019			2018

Adjusted EBITDA and Free Cash Flow are financial measures that are not in accordance with U.S. GAAP and should not be considered an alternative to net income, operating income, cash flows from operating activities, or any other measure of financial performance presented in accordance with U.S. GAAP. These measures may not be comparable to similarly titled financial metrics of other entities, as other entities may not calculate Adjusted EBITDA or Free Cash Flow in the same manner as we do. Management compensates for the limitations of Adjusted EBITDA and Free Cash Flow as an analytical ~~tool~~tools by reviewing the comparable U.S. GAAP measures, understanding the differences between the measures, and incorporating this knowledge into management’s decision-making processes. Adjusted EBITDA and Free Cash Flow should not be viewed as indicative of the actual amount of cash we have available for distributions or that we plan to distribute for a given period, nor should it be equated with “available cash” as defined in our partnership agreement.

Horsepower Utilization Rate of our Compressor Packages. We measure the horsepower utilization rate of our fleet of compressor packages as the amount of horsepower of compressor packages used to provide services as of a particular date, divided by the amount of horsepower of compressor packages in our services fleet as of such date. Management primarily uses this metric to determine our future need for additional compressor packages for our service fleet and to measure marketing effectiveness.

The following table sets forth the total horsepower in our ~~compressor~~compression fleet, our total horsepower in service, and our horsepower utilization rate as of the dates shown.


	March 31,				June 30,
	2019		2018		2019		2018
Horsepower
Total horsepower in fleet	1,167,164		1,085,088		1,155,440		1,097,546
Total horsepower in service	1,017,452		913,962		1,029,045		932,467
Total horsepower utilization rate	87.2	%	84.2	%	89.1	%	85.0	%

The following table sets forth our horsepower utilization rates by each horsepower class of our compression fleet as of the dates shown.


	March 31,				June 30,
	2019		2018		2019		2018
Horsepower utilization rate by class
Low-horsepower (0-100)	65.7	%	65.8	%	73.7	%	66.4	%
Mid-horsepower (101-1,000)	85.4	%	82.7	%
Medium-horsepower (101-1,000)					84.4	%	82.7	%
High-horsepower (1,001 and over)	95.6	%	92.9	%	97.1	%	94.1	%

The utilization figures for June 30, 2019 above reflect the impairment of certain low-horsepower class compressor packages and removal of 20,286 horsepower from the compression fleet during the second quarter of 2019.

Net Increases/Decreases in Compression Fleet Horsepower. We measure the net increase (or decrease) in our compression fleet horsepower during a given period by taking the difference between the aggregate horsepower of compressor packages added to the fleet during the period, less the aggregate horsepower of compressor packages removed from the fleet during the period. We measure the net increase (or decrease) in our compression fleet horsepower in service during a given period by taking the difference between the aggregate horsepower of compressor packages placed into service during the period, less the aggregate horsepower of compressor packages removed from service during the period.

New Equipment Sales Backlog. Our new equipment sales business includes the design, fabrication and sale of standard ~~compressor packages~~ and custom-designed compressor packages, ~~designed and fabricated~~ primarily at our facility in Midland, Texas. The equipment is fabricated to customer and standard specifications, as applicable. Our custom fabrication projects are typically greater in size and scope than standard fabrication projects, requiring more labor, materials, and overhead resources. Our fabrication business requires diligent planning of those resources and project and backlog management in order to meet the customer delivery dates and performance criteria. New equipment sales backlog was $59.7 million as of June 30, 2019 compared to $93.9 million and $105.2 millionas of March 31, 2019 and December 31, 2018, respectively. Changes in our new equipment sales backlog are a function of additional customer orders less completed orders that result in equipment sales revenues for the period. During the ~~three~~six months ended ~~March 31,~~June 30, 2019, we received cumulative orders of ~~$11.2~~$29.1 million for new compressor ~~equipment. As~~packages. Most of ~~March 31,~~our June 30, 2019 ~~our~~ new equipment sales backlog ~~was $93.9 million, all of which~~ is expected to be recognized during 2019. Our new equipment sales backlog consists of firm customer orders for which a purchase or work order has been received, satisfactory credit or financing arrangements exist, and delivery has been scheduled. Our new equipment sales backlog is a measure of marketing effectiveness that allows us to plan future labor and raw material needs and measure our success in winning bids from our customers.

Critical Accounting Policies and Estimates

There have been no material changes or developments in the evaluation of the accounting estimates and the underlying assumptions or methodologies pertaining to our Critical Accounting Policies and Estimates disclosed in our 2018 Annual Report. In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. These judgments and estimates may change as new events occur, as new information is acquired, and as changes in our operating environments are encountered. Actual results are likely to differ from our current estimates, and those differences may be material.

Revenues

Compression and related services revenues increased ~~by $9.3~~$7.8 million, ~~or 17.3%,~~a 13.8% increase, in the current year quarter compared to the prior year quarter. Growth in demand for compression services positively impacted our compression fleet utilization rates. Utilization of our medium-horsepower (101-1,000 HP) and high-horsepower (over 1,000 HP) compression fleets, which are used ~~to provide services~~ in natural gas gathering and transmission applications, ~~have~~has increased compared to the prior year quarter. As a result, the overall compression fleet horsepower utilization rate as of ~~March 31,~~June 30, 2019 increased to ~~87.2%~~89.1% compared to ~~84.2%~~85.0% as of ~~March 31,~~June 30, 2018. Our low horsepower compression fleet, which is primarily used to provide services for wellhead natural gas production enhancement, continues to experience lower utilization compared to the higher horsepower classes of our compression fleet. Primarily as a result of our medium-horsepower and high-horsepower compression fleets, we have seen our overall compression fleet horsepower utilization rate increase sequentially over the past two years. IncreasedIn addition, increased demand has also led to improved customer contract ~~pricing for compression services.~~pricing. In response to the overall improving demand for compression services, we continue to invest in growth capital projects to increase certain horsepower categories of our compression fleet.

Equipment sales revenues increased ~~$9.1~~$25.0 million ~~or 51.7%,~~ during the current year quarter compared to the prior year quarter, as we continue to see improving demand. This increase is primarily due to the increased number of customer projects compared to the prior year quarter requiring fabrication, particularly projects requiring high-horsepower compressor packages. New equipment sales backlog was $93.9 million as of March 31, 2019

compared to $105.2 million and $102.5 million as of December 31, 2018 and March 31, 2018, respectively. Changes in our new equipment sales backlog are a function of additional customer orders less completed orders that result in equipment sales revenues. Our backlog associated with new equipment sales decreased from the prior year quarter as completed customer orders, recorded as revenue during the current quarter, exceeded new orders received during the current quarter. During the year ended December 31, 2018, we reached our highest backlog since 2014, some of which was recognized as revenues during the three months ended March 31, 2019. All of our new equipment sales backlog as of March 31, 2019 is expected to be recognized as revenues in 2019.demand for high horsepower equipment. The level of revenues from equipment sales is typically volatile and difficult to forecast, as these revenues are tied to specific customer projects that vary in scope, design, complexity, and customer needs. In comparison, our revenues from compression and related services ~~and aftermarket services~~ are typically more consistent and predictable.

Cost of revenues

The ~~increase in the~~ cost of compression and related services revenue remained consistent compared to the prior year quarter, ~~was primarily due to~~despite the increased overall utilization of compressor packages. ~~The costs of compression and related services as a percentage of compression and related services revenues were 51.8% and 58.4% during the current and prior year quarters, respectively.~~ Costs of compression and related services as a percent of associated revenues decreased compared to the prior year quarter, ~~primarily~~ due to improved customer contract pricing on newly deployed equipment and ~~internal~~previously deployed equipment when contracts are renewed. In addition, there were maintenance and labor cost efficiencies resulting from the concentration and growth of newly deployed compressor equipment in our most established markets and efficiencies gained ~~on repeat orders.~~from our operating system software. These factors resulted in the highest quarterly compression services operating margin since the acquisition of CSI. The cost of compression and related services as a percentage of compression and related services revenues were 47.3% and 53.8% during the current and prior year quarters, respectively.

Depreciation and amortization

Depreciation and amortization expense primarily consists of the depreciation of compressor packages in our service fleet. In addition, it includes the depreciation of other operating equipment and facilities and the amortization of intangibles. Depreciation and amortization expense increased ~~slightly~~ compared to the prior year quarter due to increases in the compression fleet.

Impairments and other charges

During the three month period ending June 30, 2019, we recorded impairments of $2.3 million on certain units of our GasJack^(R) fleet, reflecting our decision to dispose of these units upon management's determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. There were 441 GasJack units impaired, representing 20,286 of total horsepower. Following the impairment there remains in excess of 500 GasJack units currently unutilized and available for redeployment.

Selling, general, and administrative expense

Selling,general, and administrativeexpenses remained flat during the current year quarter compared to the prior year quarter. Increased professional fees of $0.4 million and increased sales and marketing expenses of $0.1 million were offset by decreased general expenses such as office, tax, and insurance expenses of $0.5 million. Selling, general, and administrative expense as a percentage of revenues decreased in the current quarter due to the increased revenues compared to the prior year quarter.

Interest expense, net

Interest expense, net, decreased compared to the prior year quarter primarily due to the conversion and redemption of the Preferred Units resulting in lower paid in kind distributions of Preferred Units compared to the prior year period. Interest expense, net, during the current and prior year quarters also includes $0.7 million and $0.7 million, respectively, of non-cash finance cost amortization.

Series A Preferred fair value adjustment

The Series A Preferred fair value adjustment was $0.2 million charged to earnings during the current year quarter compared to $0.6 million credited to earnings during the prior year quarter. The fair value of the Preferred Units is classified as a long-term liability on our consolidated balance sheet in accordance with ASC 480 "Distinguishing Liabilities and Equity" and changes in the fair value during each quarterly period, if any, are charged or credited to earnings, as appropriate. As of June 30, 2019, the fair value of the Preferred Units was $9.0 million. The remaining outstanding Preferred Units are scheduled to be redeemed for cash on August 8, 2019.

Other (income) expense, net

Other (income) expense, net, was $0.6 million of expense, net, during the current year quarter compared to $0.4 million of income, net, during the prior yearquarter.The increase in expense is primarily due to $0.6 million of redemption premium incurred in connection with the redemption of Preferred Units for cash and by decreased foreign currency gains of $0.3 million.

Provision for income taxes

As a partnership, we are generally not subject to income taxes at the entity level because our income is included in the tax returns of our partners. Our operations are treated as a partnership for federal tax purposes with each partner being separately taxed on its share of taxable income. However, a portion of our business is conducted through taxable U.S. corporate subsidiaries. Accordingly, a U.S. federal and state income tax provision has been reflected in the accompanying statements of operations. Certain of our operations are located outside of the U.S. and the Partnership, through its foreign subsidiaries, is responsible for income taxes in these countries.

Revenues

Compression and related services revenues increased by $17.1 million, or 15.5%, in the current year period compared to the prior year period. Growth in demand for compression services positively impacted our compression fleet utilization rates. Utilization of our medium-horsepower (101-1,000 HP) and high-horsepower (over 1,000 HP) compression fleets, which are used to provide services in natural gas gathering and transmission applications, have increased compared to the prior year period. As a result, the overall compression fleet horsepower utilization rate as of June 30, 2019 increased to 89.1% compared to 85.0% as of June 30, 2018. Increased demand has also led to

improved customer contract pricing for compression services. In response to the overall improving demand for compression services, we continue to invest in growth capital projects to increase certain horsepower categories of our compression fleet.

Aftermarket services revenues increased $2.7 million, or 9.1%, during the current year period compared to the prior year period. As overall industry utilization of high-horsepower compression approaches maximum levels, customer demand for aftermarket services and parts has increased for maintenance and overhauls of customer-owned compressor equipment.

Equipment sales revenues increased $34.2 million, or 74.6%, during the current year period compared to the prior year period, as we continue to see improving demand for high-horsepower equipment. The level of revenues from equipment sales is typically volatile and difficult to forecast, as these revenues are tied to specific customer projects that vary in scope, design, complexity, and customer needs. In comparison, our revenues from compression and related services are typically more consistent and predictable.

Cost of revenues

The increase in the cost of compression and related services revenue, compared to the prior year period, was primarily due to the increased horsepower and overall utilization of compressor packages. The costs of compression and related services as a percentage of compression and related services revenues were 49.5% and 56.0% during the current and prior year periods, respectively. Costs of compression and related services as a percent of associated revenues decreased compared to the prior year period primarily due to improved customer contract pricing on newly deployed equipment and previously deployed equipment when contracts are renewed. In addition, there were maintenance and labor cost efficiencies resulting from the concentration and growth of newly deployed compression equipment in our most established markets and efficiencies gained from our operating system software. Costs of aftermarket services increased compared to the prior year period, consistent with the increased activity and part sales.

Cost of equipment sales revenues increased as a result of the increase in associated revenues. Costs of equipment sales as a percentage of equipment sales revenues increased primarily due to pricing on equipment orders placed in early 2018.

Depreciation and amortization

Depreciation and amortization expense primarily consists of the depreciation of compressor packages in our service fleet. In addition,itincludes the depreciation of other operating equipment and facilities and the amortization of intangibles. Depreciation and amortization expense increased compared to the prior year period due to increases in the compression fleet.

Impairments and other charges

During the six month period ended June 30, 2019, we recorded impairments of $2.3 million on certain units of our GasJack^(R) fleet, reflecting our decision to dispose of these units upon management's determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. There were 441 GasJack units impaired, representing 20,286 of total horsepower. Following the impairment there remains in excess of 500 GasJack units currently unutilized and available for redeployment.

Selling, general, and administrative expense

Selling, general, and administrative expenses increased during the current year ~~quarter~~period compared to the prior year ~~quarter,~~period, largely due to increased employee expenses, including wages, incentives, benefits, and other employee related expenses of ~~$2.1~~$2.2 million, and increased professional services of $0.4 million.

Interest expense, net

Interest expense, net, increased compared to the prior year ~~quarter~~period due to higher outstanding debt balances and higher interest rates associated with the issuance of our 7.50% Senior Secured Notes in March 2018. This increase was despite the reduction in interest expense from the conversion and redemption of the Preferred Units resulting in lower paid in kind distributions compared to the prior year period. Interest expense, net, during the current and prior year ~~quarter~~periods includes ~~$0.7~~$1.5 million and ~~$1.0~~$1.6 million, respectively, of finance cost amortization and other non-cash charges.

Other (income) expense, net, was ~~$0.4~~$0.2 million of ~~income~~expense during the current year ~~quarter,~~period, compared to ~~$3.2~~$2.8 million of expense during the prior year ~~quarter.~~period. This decrease in expense is primarily due to $3.5 million of

unamortized deferred financing costs charged to other expense as a result of the termination of the previous credit agreement in the prior year ~~quarter. The current year period includes approximately $0.4~~period. This decrease was offset by increased expense of $1.1 million of redemption premium incurred in connection with the redemption of Preferred Units for cash.

Provision for income taxes

As a partnership, we are generally not subject to income taxes at the entity level because our income is included in the tax returns of our partners. Our operations are treated as a partnership for federal tax purposes with each partner being separately taxed on its share of taxable income. However, a portion of our business is conducted through taxable U.S. corporate subsidiaries. Accordingly, a U.S. federal and state income tax provision has been reflected in the accompanying statements of operations. Certain of our operations are located outside of the U.S. and the Partnership, through its foreign subsidiaries, is responsible for income taxes in these countries.

Liquidity and Capital Resources

Our primary cash requirements are for distributions, working capital requirements, debt service, normal operating expenses, and capital expenditures. Our potential sources of funds are our existing cash balances, cash generated from our operations, long-term and short-term borrowings, financing transactions with TETRA, issuances of debt and equity securities, and leases, which we believe will be sufficient to meet our working capital and planned growth requirements during 2019. ~~Continued competitive market environments have resulted in ongoing challenges in each of our domestic~~Though demand for compression services and ~~international business regions. We~~equipment is currently high, we are monitoring the ~~2019~~ spending plans of our customers due to oil and gas price volatility and its impact on our customer's demand for our products and services. If oil and gas prices decrease further during 2019, our businesses could be negatively impacted. In addition, current conditions in the market for debt and equity securities in the energy sector have increased the difficulty of obtaining equity and debt financing to grow our business. Despite these challenges, we remain committed to a long-term growth strategy. Our near-term focus is to selectively expand our compression fleet to serve the growing demand for compression services, while continuing to preserve and enhance liquidity through strategic operating and financial measures.

On December 20, 2018, we announced that, given the decline in our common unit price, we were reducing our common unit distributions from $0.75 per unit per year (or $0.1875 per quarter) to $0.04 per unit per year (or $0.01 per quarter) for a period of up to four quarters, beginning with the February 2019 distribution. We intend to use the approximately $34 million of savings from the reduced distribution to redeem the remaining Preferred Units for cash and avoid the dilution to our common unitholders that would occur if the Preferred Units were converted into common units. The stated value of the Preferred Units as of May 8, 2019 was approximately $13.3 million.

We expect to fund any future capital expenditures, along with potential acquisitions, if any, with existing cash balances, cash flow generated from our operations, financing transactions with TETRA and funds received from the issuance of additional debt and equity securities. We may also seek to expand our compression fleet

through finance or operating leases with third parties. However, we are subject to business and operational risks that could materially adversely affect our cash flows and together with risks associated with current debt and equity market conditions, our ability or desire to issue such securities. Please read Part I, Item 1A "Risk Factors" included in our 2018 Annual Report.

Meeting increased demand for our compression services, ~~both internationally and in the U.S.,~~ will require ongoing capital expenditure investment, which could be significant. The level of future growth capital expenditures depends on demand for compression services, the level of cash available to fund these expenditures, and our decisions whether to utilize available cash to fund increases in our quarterly common unit distribution, ~~increases,~~ retire debt, or make capital expenditures. We anticipate capital expenditures in 2019 to range from ~~$60.0~~$65.0 million to ~~$65.0~~$70.0 million. These capital expenditures include approximately $18.0 million to $20.0 million of maintenance capital expenditures and approximately ~~$42~~$47 million to ~~$45~~$50 million of capital expenditures primarily associated with the expansion of our compression services fleet. We expect that the combination of ~~$16.9~~$4.3 million of cash on hand at ~~March 31,~~June 30, 2019 and operating cash flows expected to be generated during the ~~remainder of the~~ year will be sufficient to fund the remainder of these capital expenditures

without having to incur additional long-term debt and without having to access the equity markets. In addition to these capital expenditures, pursuant to agreements executed in February 2019, TETRA has agreed to fund the construction of and purchase up to $15.0 million of new compression services equipment and lease it to us in exchange for a monthly rental fee. During the ~~three~~six months ended ~~March 31,~~June 30, 2019, ~~$2.4~~$11.1 million of the $15.0 million ~~was paid to us from TETRA.

Maintenance capital expenditures ~~also~~ increased during the ~~three~~six months ended ~~March 31,~~June 30, 2019 compared to the prior year period. Total capital expenditures, net of disposals and proceeds, during the current year period of ~~$23.2~~$39.6 million include ~~$5.7~~$10.6 million of maintenance capital expenditures and are net of ~~$0.9~~$1.0 million of non-cash cost of fleet compression units sold. The level of growth capital expenditures depends on

forecasted demand for compression services. If the forecasted demand for compression services during 2019 increases or decreases, the amount of planned expenditures on

growth and expansion will be adjusted, subject to the availability of funds. We continue to review all capital expenditure plans carefully in an effort to conserve cash and fund our liquidity needs.

Financing Activities

Beginning with the distribution to common unitholders during February 2019, we reduced our common unit distributions from $0.75 per unit per year (or $0.1875 per quarter) to $0.04 per unit per year (or $0.01 per quarter). We ~~intend to use~~have used the ~~approximately $34 million of~~cash savings from the reduced distribution to redeem the remaining Preferred Units for cash and avoid the further dilution to our common unitholders that would occur if the Preferred Units were converted into common units. Accordingly, during the ~~three~~six months ended ~~March 31,~~June 30, 2019, we distributed ~~$0.5~~$1.0 million of cash distributions to our common unitholders and General Partner.

Our sources of funds for liquidity needs are existing cash balances, cash generated from our operations, and long-term and short-term borrowings. In addition to redeeming the remaining Preferred Units, we anticipate that we will utilize available cash to fund our anticipated growth capital expenditures. In February 2019, we entered into a transaction with TETRA whereby TETRA agreed to fund the construction of and purchase up to $15 million of new ~~compression~~compressor services equipment and agreed to lease it to us in exchange for a monthly rental fee. As of ~~March 31,~~June 30, 2019, pursuant to this arrangement, ~~$2.4~~$11.1 million has been ~~paid to us from~~funded by TETRA for the construction of new ~~compression~~compressor equipment.

Series A Convertible Preferred Units. The Preferred Units rank senior to all classes or series of equity securities of the Partnership with respect to distribution rights and rights upon liquidation. The holders of Preferred Units receive quarterly distributions, which are paid in kind in additional Preferred Units, equal to an annual rate of 11.00% of the Issue Price (or $1.2573 per Preferred Unit annualized) of their outstanding Preferred Units, subject to certain adjustments.

Unless otherwise redeemed for cash, a ratable portion of the Preferred Units has been, and will be, converted into common units on the eighth day of each month over a period of thirty months that began in March 2017 and will end in August 2019 (each, a “Conversion Date”). Beginning with the January 2019 Conversion Date, we have elected to redeem the remaining Preferred Units for cash, resulting in ~~783,046~~1,870,681 Preferred Units being redeemed during the ~~three~~six months ended ~~March 31,~~June 30, 2019 for ~~$9.4~~$22.5 million, which includes approximately ~~$0.4~~$1.1 million of redemption premium that was paid. Including the impact of paid in kind distributions of Preferred Units and the conversions of Preferred Units into common units, and the redemptions of Preferred Units for cash, the total number of Preferred Units outstanding as of ~~March 31,~~June 30, 2019 was ~~1,779,417. As of May 8, 2019, the total number of Preferred Units outstanding was 1,165,756, having an aggregate stated value of approximately $13.3 million.~~

751,736. The ~~fair value~~last redemption of the Preferred Units as of March 31, 2019 was $20.9 million. Changes in the fair value during each quarterly period, if any, are charged or credited to earnings in the accompanying consolidated statements of operations. Charges or credits to earnings for changes in the fair value of theremaining Preferred Units, along with ~~the interest expense~~a final cash payment made in lieu of paid in kind units for the ~~accrual and~~quarter ended June 30, 2019, is scheduled to occur on August 8, 2019 for an aggregate cash payment of ~~paid-in-kind distributions associated with the Preferred Units, are non-cash charges or credits associated with the Preferred Units.~~$5.0 million.

Bank Credit Facilities. The Credit Agreement, as amended, includes a maximum credit commitment of $50.0 million available for loans, letters of credit (with a sublimit of $25.0 million) and swingline loans (with a sublimit of $5.0 million), subject to a borrowing base to be determined by reference to the value of the Partnership’s and any other Borrowers’ accounts ~~receivable.~~receivable and certain inventory. Such maximum credit commitment may be increased by $25.0 million in accordance with the terms and conditions of the Credit Agreement. As of ~~March 31,~~June 30, 2019, and subject to compliance with the covenants, borrowing base, and other provisions of the agreements that may limit borrowings under the Credit Agreement, we had availability of ~~$18.4~~$22.2 million.

The maturity date of the Credit Agreement is June 29, 2023. As of ~~March 31,~~June 30, 2019, we had no outstanding balance and had ~~$3.5~~$4.5 million in letters of credit against our Credit Agreement. As of ~~May 8,~~August 7, 2019, we have no balance outstanding under our Credit Agreement and ~~$5.3~~$3.7 million in letters of credit, leaving availability under the CCLP Credit Agreement of ~~$16.6 million.~~$31.6 million, reflecting recent increases to the borrowing base.

7.50% Senior Secured Notes. As of ~~May 8,~~August 7, 2019, $350.0 million in aggregate principal amount of our 7.50% Senior Secured Notes are outstanding. The 7.50% Senior Secured Notes accrue interest at a rate of 7.50% per annum and are scheduled to mature on April 1, 2025.

7.25% Senior Notes. As of ~~May 8,~~August 7, 2019, $295.9 million in aggregate principal amount of our 7.25% Senior Notes are outstanding. The 7.25% Senior Notes accrue interest at a rate of 7.25% per annum and are scheduled to mature on August 15, 2022.

Off Balance Sheet Arrangements

As of ~~March 31,~~June 30, 2019, we had no “off balance sheet arrangements” that may have a current or future material effect on our consolidated financial condition or results of operations.

Recently Adopted Accounting Guidance

We adopted the new lease accounting standard on January 1, 2019. The new lease standard had a material impact to our consolidated financial statements, resulting from the inclusion of operating lease right-of-use assets and operating lease liabilities in our consolidated balance sheet. Refer to Part I, Item 1. Financial Statements- Note A - "Organization, Basis of Presentation and Significant Accounting Policies" and Note J - “Leases” for further discussion.

Commitments and Contingencies

From time to time, we are involved in litigation relating to claims arising out of our operations in the normal course of business. While the outcome of these lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

Contractual Obligations

Our contractual obligations and commitments principally include obligations associated with our outstanding indebtedness and obligations under operating leases. During the first ~~three~~six months of 2019, there were no material

changes outside of the ordinary course of business in the specified contractual obligations.

For additional information about our contractual obligations as of December 31, 2018, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2018 Annual Report.

Cautionary Statement for Purposes of Forward-Looking Statements

Forward-looking statements in this Quarterly Report are identifiable by the use of the following words, the negative of such words, and other similar words: “anticipates”, “assumes”, “believes”, “budgets”, “could”, “estimates”, “expects”, “forecasts”, “goal”, “intends”, “may”, “might”, “plans”, “predicts”, “projects”, “schedules”, “seeks”, “should, “targets”, “will” and “would”.

Such forward-looking statements reflect our current views with respect to future events and financial performance and are based on assumptions that we believe to be reasonable but such forward-looking statements

are subject to numerous risks, and uncertainties, including, but not limited to:

economic and operating conditions that are outside of our control, including the supply, demand, and prices of oil and natural gas;

the availability of adequate sources of capital to us;

our existing debt levels and our flexibility to obtain additional financing;

our ability to continue to make cash distributions, or increase cash distributions from current levels, after the establishment of reserves, payment of debt service and other contractual obligations;

the restrictions on our business that are imposed under our long-term debt agreements;

our dependence upon a limited number of customers and the activity levels of our customers;

the levels of competition we encounter;

our ability to replace our contracts with customers, which are generally short-term contracts;

the availability of raw materials and labor at reasonable prices;

risks related to acquisitions and our growth strategy;

•	other risks and uncertainties under “Item 1A. Risk Factors” in our 2018 Annual Report, and as included in our other filings with the U.S. Securities and Exchange Commission ("SEC"), which are available free of charge on the SEC website at www.sec.gov.

The risks and uncertainties referred to above are generally beyond our ability to control and we cannot predict all the risks and uncertainties that could cause our actual results to differ from those indicated by the forward-looking statements. If any of these risks or uncertainties materialize, or if any of the underlying assumptions prove incorrect, actual results may vary from those indicated by the forward-looking statements, and such variances may be material.

Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to update or revise any forward-looking statements we may make, except as may be required by law.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. We do not take title to any natural gas or oil in connection with our services and, accordingly, have no direct exposure to fluctuating commodity prices. For a discussion of our indirect exposure to fluctuating commodity prices, please read “Risk Factors — Certain Business Risks” in our 2018 Annual Report. We depend on domestic and international demand for and production of natural gas and oil and a reduction in this demand or production could adversely affect the demand or the prices we charge for our services, which could impact our revenues and cash available for distribution to our common unitholders in the future. We do not currently hedge, and do not intend to hedge, our indirect exposure to fluctuating commodity prices.

Interest Rate Risk

Through ~~March 31,~~June 30, 2019, there have been no material changes in the information pertaining to our interest rate risk exposures as disclosed in our 2018 Annual Report. There is no balance outstanding under the Credit Agreement as of ~~March 31,~~June 30, 2019. As such, we currently do not have any long-term debt obligations that have a variable rate of interest.

Exchange Rate Risk

As of ~~March 31,~~June 30, 2019, there have been no material changes pertaining to our exchange rate exposures as disclosed in our 2018 Annual Report.

Item 4. Controls and Procedures.

Under the supervision and with the participation of our management, including the Principal Executive Officer and Principal Financial Officer of our General Partner, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, the Principal Executive Officer and Principal Financial Officer of our General Partner concluded that our disclosure controls and procedures were effective as of ~~March 31,~~June 30, 2019, the end of the period covered by this quarterly report.

In connection with the adoption of the new lease accounting standard on January 1, 2019, we evaluated and updated certain internal controls to facilitate the proper capture and assessment of contractual information required to support proper preparation of financial information upon adoption.

There were no ~~other~~ changes in our internal control over financial reporting that occurred during the fiscal quarter ended ~~March 31,~~June 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
