ARC Group Worldwide Reports Fiscal Year First Quarter 2018 Results

DELAND, FL., November 13, 2017—ARC Group Worldwide, Inc. (“ARC” or the “Company”) (NASDAQ: ARCW), a leading global provider of advanced manufacturing and metal 3D printing solutions, today reported its results for the period ending October 1, 2017, its fiscal first quarter 2018.

Quarterly Financial Summary

Fiscal first quarter 2018 revenue from continuing operations was $19.9 million, compared to $25.7 million for the fiscal first quarter of 2017.  The decrease in sales was primarily driven by lower MIM and plastics sales, most notably in the firearm and defense sectors.  Lower production volumes impacted the Company’s operational efficiency during the quarter, as gross profit from continuing operations was $1.4 million, compared to $4.7 million for the prior year period.

Selling, general and administrative expenses for the fiscal first quarter 2018 declined to $3.5 million, down from $4.9 million in the prior year period.  Expense reductions were primarily attributable to the Company’s recent cost elimination initiatives.

EBITDA from continuing operations for the fiscal first quarter 2018 was $0.4 million, compared to the prior year period of $1.4 million.  Net loss from continuing operations for the fiscal first quarter 2018 was $3.3 million, compared to net loss from continuing operations of $0.7 million for the prior year period.

Fiscal first quarter 2018 net loss was $3.6 million, compared to net income of $3.6 million for the fiscal first quarter of 2017.  Prior year results included the $4.3 million benefit associated with and from the sale of the Company’s non-core subsidiaries.

ARC’s interim CEO and CFO, Drew M. Kelley, commented, “Management remains focused on returning the Company to profitability, while driving cash flow and rightsizing the balance sheet.  While certain markets we service remain challenged, the Company is not taking a passive approach towards improving top and bottom line results.  Specifically, the Company recently implemented a new cost saving program which we estimate will eliminate approximately $3.3 million in expenses per year.  Notably, these cost reductions are incremental to previously announced initiatives, which are estimated to eliminate approximately $6.0 million in annual costs.  While we expect the decline in sales to be temporary, our focus on operational efficiency and cost reduction will be ongoing.  Thus, a further review of the recent operating results suggest once our combined cost reduction initiatives take hold, we can expect to achieve similar profitability and margins despite lower top line results.  Thereafter, with the eventual return of normalized revenue levels, overall profitability could exceed historic results.”

Mr. Kelley continued, “At the same time, our metal 3D business continues to advance, both technically and financially, recording robust sequential revenue growth and record EBITDA during the quarter.  As a result of this continued improvement, the Company is evaluating additional investment opportunities to further accelerate the pace of growth.”

GAAP to Non-GAAP Reconciliation

The Company has provided non-GAAP financial information to provide additional, meaningful comparisons of current results to prior periods’ results by excluding items that the Company does not believe are representative or indicative of its results of operations.  Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States.  The Company’s non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures, and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.  Specifically, EBITDA from Continuing Operations, EBITDA Margin from Continuing Operations, Facility EBITDA from Continuing Operations, Facility EBITDA Margin from Continuing Operations, Adjusted Earnings, and Adjusted Earnings Per Share are non-GAAP financial measures.  EBITDA Margin from Continuing Operations and Facility EBITDA Margin from Continuing Operations are calculated by dividing EBITDA from Continuing Operations and Facility EBITDA from Continuing Operations, respectively, by sales.

The reconciliation to GAAP is as follows (dollars in thousands):

EBITDA from Continuing Operations excludes interest expense, net and income taxes as these items are associated with our capitalization and tax structures.  EBITDA from Continuing Operations also excludes depreciation and amortization expense as these non-cash expenses reflect the impact of prior capital expenditure decisions, which may not be indicative of future capital expenditure requirements.  EBITDA from Continuing Operations excludes the (income) or loss associated with discontinued operations.

Facility EBITDA from Continuing Operations consists of EBITDA from our operating segments.  We believe this is a meaningful measurement of the operating performance of our manufacturing facilities.  Corporate expenses primarily consist of costs not allocated to our manufacturing facilities, such as compensation related costs for employees assigned to corporate, board of directors fees and expenses, professional fees, insurance costs, and marketing costs.

Adjusted Earnings removes the impact of reorganization/transaction related expenses and the impact of discontinued operations.  Reorganization expenses are primarily labor and labor related costs associated with the termination of employees.  Transaction expenses are primarily professional fees related to the refinancing of debt and the sale of non-core assets.
