IMAGINE MORE Too often, we settle. We settle for the average. The ordinary. The run of the mill. We tell ourselvesthisisjustthewayit is.thisisasgoodasitgets.and that we should simply accept what is presented, and make do. But, wouldn t it be nice to give ourselves permission to imagine more? FTSI is a company where imagining more isn t just encouraged, it s expected. It s a place where limits simply don t exist. And the opportunity to succeed is within everyone s grasp, every single day.

COMPELLING INVESTMENT THESIS Large, pure play provider of hydraulic fracturing services Market leading positions in the most active basins 1.7 million total HHP across 34 total fleets (1) with idle fleets ready to be reactivated quickly and cost effectively Vertically integrated with in house manufacturing that drives what we believe are the lowest opex and capex requirements in the industry Culture built on safety and innovation Low cost structure allows us to maximize returns in any market Highest free cash flow yield in the industry 3Q annualized yield was 18% (2) (1) Including one newbuild fleet (50,000 HHP) under construction. (2) Annualized yield calculated by taking third quarter 2018 free cash flow, excluding changes in operating assets and liabilities and multiplying it by four; then dividing by common shares outstanding; then dividing the result by the third quarter 2018 VWAP. Please see page 22 for reconciliation of free cash flow and free cash flow, excluding changes in operating assets and liabilities, to net income. 4

VERTICAL INTEGRATION DELIVERS SIGNIFICANT COST ADVANTAGES Operating Expenses Maintenance Capex Growth Capex We manufacture our own fluid ends and perform substantially all recurring maintenance in house We perform all engine, transmission and blender refurbs in house We manufacture and rebuild all of our own power ends We build all of our new fleets and implement design enhancements Ancillary equipment like blenders also built in house ~50% cost advantage versus buying fluid ends from third parties ~$2.5 million per fleet per year; one of the lowest maintenance capex requirements in the industry Newbuild cost of ~$25 million per 50k HHP fleet including all ancillary equipment Outstanding Returns on Investment 7

CENTRALIZED FLEET MONITORING ENABLES CONSISTENT, RELIABLE OPERATIONS National Operations Center operates 24/7, monitoring real time job and equipment data Centralized location of engineering functions enables sharing of knowledge and best practices across organization Dedicated workstation for each fleet Assists in development of equipment automation algorithms Enhances customers data analytics capabilities 8

OTHERS WAIT WHILE WE CREATE Only top 1% of the market fully leverages 21 st century technology to optimize equipment performance and design 2016 Stage 1 Catch Failures 2017 Stage 2 Reduce Damage 2018+ Stage 3 Change Behavior Smoke detector model Immediate identification of anomalies We began monitoring vibrations on all of our fleets allowing us to create a baseline of normal operating conditions Cloud based machine health monitoring Early warnings based on predicative models that leverage historical data Utilized vibration signatures to augment operations and reduce damage accumulation Identify and mitigate root causes of failure Led to re designs of our fluid ends to allow for longer life and materials cost optimization Supported re design of other components to reduce wear and tear upstream from our pumps 9

CULTURE OF INNOVATION PAYS DIVIDENDS......AND WE THINK IT IS ONLY THE BEGINNING We Increased Fluid End Life Over 45% in 2018......Which Helped Bring Non Productive Time (NPT) Down by >25% Minimizing NPT time is a major focus at FTSI and has helped improve customer satisfaction Pumping Hours per Fluid End 2017 2018 4Q '18 Fluid End Spend per Pumping Hour Non Pumping Time per Pumping Day 1H18 Pump Time per Pumping Day 2H18 Ongoing Initiatives National Operations Center (NOC) NOC has helped reduced engineering costs by >40% since the opening of the NOC while also enabling sharing of best practices Faster recognition of equipment issues on site enables costsaving preventative maintenance Ability to identify and differentiate human error from normal equipment wear in real time Data Analytics Data analytics and additional equipment sensors have enabled: Major repairs in 2018 accounted for 4% of work orders compared to 7% in 2017 Average cost of repairs in 2018 was down 18% compared to 2017 Continued design enhancements of fluid ends Initial steps toward equipment automation 10

RETURNS-FOCUSED APPROACH ~$18mm EBITDA per fleet (1) ~$2.5mm Maintenance capex per fleet Zero Effective federal tax rate (2) Best in class free cash flow Solid operational execution with a focus on efficiency Low operating expenses, low SG&A, and low maintenance capex Tax amortization of goodwill and NOLs eliminate cash taxes (1) Represents preliminary estimate of 2018 Adjusted EBITDA per fleet. Utilizes Adjusted EBITDA, excluding a supply commitment charge, for 3Q 2018. Utilizes the midpoint of the range provided in the preliminary fourth quarter 2018 financial and operational results filed with the SEC on February 11, 2019 for Q4 2018 Adjusted EBITDA. (2) Due to tax amortization of intangible assets and utilization of net operating loss carryforwards. 11

CASH GENERATION FTSI IS BEST IN THE BUSINESS Free Cash Flow Comparison (1) Adjusted EBITDA Less Capex Comparison (2) $307M $388M $309M $116M FTSI Peer 1 Peer 2 Peer 3 Peer 4 Peer 5 Peer 6 Peer 7 FTSI Peer 1 Peer 2 Peer 3 Peer 4 Peer 5 Peer 6 Peer 7 / 2017 / LTM 3Q18 / 2017 / LTM 3Q18 FTSI generated over $300 million of FCF over the LTM (3), $225 million more than closest peer Vertical integration and focus on efficiency enabled FTSI to generate nearly $400 million in EBITDA less Capex over the LTM (3), $135 million more than closest peer (1) Free cash flow is defined as Cash Flows from Operating Activities less Capital Expenditures. See page 21 for a calculation of FTSI s free cash flow. Peer set includes: CJ, FRAC, LBRT, PTEN, PUMP, RES, SPN. (2) Peer set includes: CJ, FRAC, LBRT, PTEN Pressure Pumping Segment, PUMP, RES, SPN. FTSI Adjusted EBITDA excludes a $10 million non cash supply commitment charge recorded in 3Q 2018. PUMP Adjusted EBITDA includes loss on disposal of assets, which represents the fluid ends that the company capitalizes (all other peers expense fluid ends costs). See page 19 for a reconciliation of FTSI s Adjusted EBITDA less Capital Expenditures to Net Income (Loss). (3) Last twelve months ended September 30, 2018. 12

CONSISTENT DELEVERAGING $ in millions $1,400 $1,200 $1,000 $1,081 $1,069 $1,014 $922 ~$750M reduction in net debt $800 $600 $400 $580 $509 $398 $508 $330 $447M more than IPO proceeds $200 $ 1Q17 2Q17 3Q17 4Q17 1Q18 2Q18 3Q18 4Q18 Net Debt (1) (2) Gross Debt Since the beginning of 2017 we have significantly reduced our debt to a very manageable level and will continue to delever in 2019 (1) Excludes unamortized discount and debt issuance cost. Calculated as total principal amount of debt less cash and cash equivalents. See page 20 for a reconciliation of net debt, excluding unamortized discount and debt issuance costs, to long term debt debt. (2) Represents principal amount of debt commonly referred to as gross debt. 13

FTSI S VALUE PROPOSITION Given the illustration below, we believe FTSI receives little credit for its in house manufacturing and tax saving attributes, which provide us with a substantial cash flow advantage over our peers Illustrative Sum of the Parts Starting Point: Public Valuation of FTSI $1.2B Market cap as of Feb. 8, 2019 plus long term debt, less cash and cash equivalents as of Dec. 31, 2018 Less: Est. Value of In house Manufacturing Savings $630M Estimated annual operating expense of ~$70M (on 20 fleets) times median equipment manufacturer EBITDA multiple of 9x (1) Less: Est. Value of Tax Saving Attributes (2) $320M Approximately $3B of tax saving attributes times 21% assumed tax rate discounted for 15 years at 10% Implies: Est. Value of FTSI Operations $250M ~$150 per HHP (3) ~$2.50 per Share (4) ~1.3x 19 Consensus EBITDA (5) Once you back out the estimated value of our in house manufacturing and tax attributes you are left with a low valuation on the core of our business (1) Per FactSet as of February 8, 2019. Equipment Manufacturer peer set includes: CFX, DOV, GDI, OIS, WEIR. Estimates are based on calculations of figures that have been prepared internally by management and we cannot provide any assurances that others would attribute the same value to our in house manufacturing capabilities. See Cautionary Statement Regarding Forward Looking Statements. (2) A Section 382 change of control event could defer or limit the tax benefits depending on the value of the company at the time of a change in control event. We cannot provide any assurances that we will be able to utilize all or any of the tax attributes described above, See Cautionary Statement Regarding Forward Looking Statements. (3) Based on 1.7M total HHP (including one newbuild fleet). (4) Based on common shares outstanding at September 30, 2018. (5) Consensus EBITDA adjusted to exclude $70M of in house operating expense savings to eliminate double counting of savings in illustrative sum of the parts. Consensus EBITDA per FactSet as of February 8, 2019. 14

OPERATIONAL UPDATE Adapting Quickly to Changing Environment... Based on discussions with our customers, we currently expect to deploy one or two additional fleets in the first quarter 2019 Ample idle capacity and ability to reactivate quicker than competition should facilitate market share gains upon a market recovery Average Active Fleets 21 20 19 19 20 Efforts focused on deployments under dedicated agreements 18 4Q '18 Actual 1Q '19 Estimate...However Pricing Still Challenging... Pricing was slightly lower than expected in 4Q 18 due to further market compression and commodity price uncertainty Pricing pressure has continued in the first quarter 2019, which will lower our annualized adjusted EBITDA per fleet further...but Expect Consistent Cash Flow That Supports Continued Deleveraging Continue to generate positive cash flow further deleveraging our balance sheet Repaid $57M of debt since September 30, 2018 and over $620M in 2018 Net Debt ($M) $450 $400 $350 $300 $398 $330 3Q '18 4Q '18 15

The most comparable financial measure to Adjusted EBITDA under GAAP is net income or loss. Adjusted EBITDA is used by management to evaluate the operating performance of the business for comparable periods and Adjusted EBITDA is a metric used for management incentive compensation. Adjusted EBITDA should not be used by investors or others as the sole basis for formulating investment decisions, as it excludes a number of important items. The Company believes Adjusted EBITDA is an important indicator of operating performance because it excludes the effects of its capital structure and certain non cash items from its operating results. Adjusted EBITDA is also commonly used by investors in the oilfield services industry to measure a company's operating performance, although FTSI s definition of Adjusted EBITDA may differ from other industry peer companies. Please see FTSI s 10Q filed with the SEC on October 30, 2018 for more information about the supply commitment charges, and why management believes this charge should be excluded from 3Q18 results for comparability purposes with prior periods. 17

Adjusted EBITDA, excluding a supply commitment charge, is a non GAAP measure that further adjusts Adjusted EBITDA to exclude a supply commitment charge. The most comparable financial measure to Adjusted EBITDA, excluding a supply commitment charge, under GAAP is net income or loss. Adjusted EBITDA, excluding a supply commitment charge, is used by management to evaluate the operating performance of the business for comparable periods and Adjusted EBITDA is a metric used for management incentive compensation.
