Preliminary Results for the Three Months and Six Months Ended June 30, 2019

The following includes preliminary financial results of Nesco for the three months and six months ended June 30, 2019. Nesco has not finalized its financial statements for the three and six months ended June 30, 2019 and, consequently, you should not place undue reliance on this preliminary information. For the three months ended June 30, 2019, Nesco expects its revenue to be in the range of $62.5 million to $63.5 million, net loss to be between $5.8 million to $4.8 million and Adjusted EBITDA to be between $30.0 million and $31.0 million. For the six months ended June 30, 2019, Nesco expects its revenue to be in the range of $124.0 million to $125.0 million, net loss to be between $12.5 million to $11.5 million, Adjusted EBITDA to be between $60.4 million and $61.4 million and Run-Rate Adjusted EBITDA for the twelve-month period ended June 30, 2019, to be between $130.9 million and $132.1 million.

Nesco’s business plan includes investment in new equipment units to grow its fleet and an expansion of its PTA segment by adding locations. In the quarter ended June 30, 2019, Nesco accelerated several of the initiatives included in its business plan for 2019. This included (1) accelerating its equipment purchase program, shifting capital expenditures planned for the second half of 2019 into the second quarter of 2019, providing an opportunity to capture additional revenue and EBITDA from new units being added to the fleet sooner than the base plan called for and (2) accelerating the roll-out of new PTA locations, providing an opportunity to capture additional revenue and EBITDA sooner than in the plan. The investments under Nesco’s business plan and the acceleration of these initiatives resulted in an increase in the borrowings under Nesco’s revolving credit facility (the “Existing Nesco ABL Facility”) from $215.0 million as of March 31, 2019 to $243.0 million as of June 30, 2019.

Nesco has prepared an adjustment to Adjusted EBITDA in order to reflect the full-year impact to Adjusted EBITDA of the additional capital expenditures related to equipment added to the fleet during the twelve-month period ended June 30, 2019. This adjustment is calculated assuming that the net units added to the fleet in the period had been part of the fleet from the first day of the period. The adjustment is calculated by subtracting the average fleet count for the twelve-month period ended June 30, 2019 from the ending fleet count as of June 30, 2019, and multiplying that number by the average rate per day for the period, multiplied by the average utilization for the period, multiplied by 365 days in the period, and applying an 80.0% estimated Adjusted EBITDA margin on that incremental revenue.

The following table reconciles (i) Nesco’s estimated net income to its estimate of Adjusted EBITDA for the three and six months ended June 30, 2019, (ii) Nesco’s net income to Adjusted EBITDA for the three and six months ended June 30, 2018 and (iii) Nesco’s estimated net income to its estimate of Adjusted EBITDA for the twelve months ended June 30, 2019.
