THIRD QUARTER CONSOLIDATED RESULTS

On a consolidated basis, revenues increased 17.4 percent to $456.7 million, driven by a 5.4 percent increase in Aerospace Solutions Group segment (“ASG”) revenues and a 121.6 percent increase in Energy Services Group (“ESG”) revenues. Operating earnings and operating margin of $60.5 million and 13.2 percent increased by 56.7 percent and approximately 330 basis points, respectively, reflecting an approximate 80 basis point expansion in ASG’s operating margin and continued strong year-over-year improvement at ESG. Adjusted Net Earnings and Adjusted Net Earnings per diluted share increased 55.9 percent and 60.0 percent to $44.9 million and $0.88 per diluted share, respectively.

Amin J. Khoury, KLX’s Chairman and Chief Executive Officer, stated, “We are pleased with the third quarter operating results at both our ASG and ESG businesses. Our ASG segment delivered revenue growth, margin expansion and solid free cash flows. We are also pleased to report that ASG continued its market momentum with three new contract awards and market share gains valued at approximately $125 million in the aggregate, supporting the F-35 Joint Strike Fighter, Pratt & Whitney’s new GTF engine and Bombardier’s C-Series commercial aircraft.” Mr. Khoury continued, “Our ESG segment generated very strong revenue growth and operating performance during the third quarter, delivering positive EBITDA and reinforcing our expectation for achieving positive operating earnings in the fourth quarter of this year.”

THIRD QUARTER SEGMENT RESULTS

The following is a tabular summary and commentary of revenues, operating earnings and Adjusted EBITDA, for the three month periods ended October 31, 2017 and October 31, 2016 ($ millions):

2

For the three months ended October 31, 2017, ASG revenues of $367.6 million increased 5.4 percent compared to the same period in the prior year. The increase in revenues was driven by a mid-single digit percentage increase in sales to commercial aerospace manufacturing customers, including initial revenue contributions from new business awards announced in 2016, partially offset by a decrease in demand from business jet manufacturing customers. Aftermarket revenues increased by approximately 3.6 percent as compared to the prior year. ASG operating earnings of $62.4 million increased 10.4 percent, and operating margin of 17.0 percent expanded approximately 80 basis points. ASG Adjusted EBITDA of $73.9 million was 20.1 percent of revenues and increased 10.1 percent as compared to the prior year period.

For the three months ended October 31, 2017, as compared to the same period of the prior year, ESG revenues of $89.1 million increased 121.6 percent, operating loss decreased $16.0 million, or 89.4 percent, to $(1.9) million, and Adjusted EBITDA of $9.4 million improved by $16.1 million. As compared to the second quarter of 2017, revenues increased by 21.2 percent, operating loss improved by 75.6 percent, and Adjusted EBITDA improved by 147.4 percent.

For the nine months ended October 31, 2017, GAAP basis net earnings and net earnings per diluted share were $64.9 million and $1.26 per share, increases of 114.2 percent and 117.2 percent, respectively.

NINE MONTH SEGMENT RESULTS

The following is a tabular summary and commentary of revenues, operating earnings and Adjusted EBITDA, for the nine month periods ended October 31, 2017 and October 31, 2016 ($ millions):

4

For the nine months ended October 31, 2017, ASG revenues of $1.07 billion increased 6.0 percent compared to the same period in the prior year. Revenues from both commercial aerospace manufacturing and aftermarket customers increased by an approximate mid-single digit percentage. ASG operating earnings of $181.2 million increased 8.8 percent and operating margin increased approximately 40 basis points to 16.9 percent.

5

percent of net earnings and 138.5 percent of Adjusted Net Earnings. Capital expenditures were $25.0 million, reflecting investments related to the Company’s new 550,000 square foot ASG Miami global distribution and operations center, and discrete investments within the ESG business. As of October 31, 2017, cash on hand was approximately $287.5 million. Total long-term debt of $1.2 billion less cash, resulted in net debt of $912 million, and the Company’s net debt to net capital ratio was approximately 29 percent. There were no borrowings outstanding under the Company’s $750.0 million credit facility. Over the past three and nine month periods ended October 31, 2017, the Company repurchased approximately $50 million and $80 million of KLXI common stock at an average price of $47.46 and $48.09 per share, respectively.

OUTLOOK

Mr. Khoury commented, “We are raising our 2017 Adjusted Net Earnings per diluted share guidance by $0.10 to approximately $3.10 per diluted share. The improved outlook is based on a lower share count as a result of our share buyback program, together with an approximate $0.06 per share benefit from lower taxes. For the full year, we anticipate revenues to increase approximately 17 percent to approximately $1,750 million and operating earnings to increase approximately 72 percent to approximately $222 million. Adjusted Net Earnings and Adjusted Net Earnings per diluted share are both expected to increase approximately 70 percent to approximately $159 million and approximately $3.10 per diluted share, respectively. Early in 2018, we expect to begin the consolidation and relocation of several facilities into our new ASG Miami global distribution and operations center. Our 2018 outlook excludes approximately $20 million of moving costs, asset write-offs for abandoned equipment, lease buyouts and other similar items related to this transition.”

Mr. Khoury continued, “We remain optimistic about the outlook for both our ASG and ESG businesses. Within ASG, we expect the revenue contribution from new program awards achieved in 2016 will continue their initial ramp up in the fourth quarter and into 2018. Furthermore, we expect to continue to press our advantage of superior service to gain additional new business in the coming quarters. Our ESG segment continues to benefit from the improvement in oil and gas prices, which has driven an increase in capital expenditures by our oil and gas exploration and production customers.”

The Company’s Fiscal 2018 initial outlook excludes approximately $20 million of new facility transition costs and is as follows:

6

·                        2018 revenues are expected to increase by approximately 10 percent to approximately $1,950 million

·                        Operating earnings are expected to increase approximately 30 percent to approximately $290 million

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

This release includes “Adjusted Net Earnings” and “Adjusted Net Earnings per diluted share” to reflect net earnings before amortization, non-cash compensation expense, and to include the tax benefit from the amortization of tax deductible goodwill. This release also includes “Adjusted EBITDA,” which excludes depreciation and amortization and non-cash compensation expense, and free cash flow, which are “non-GAAP financial measures” as defined in Regulation G of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Company uses the above described adjusted measures to evaluate and assess the operational strength and performance of the business and of particular segments of the business. The Company believes these financial measures are relevant and useful for investors because it allows investors to have a better understanding of the Company’s actual operating performance unaffected by the impact of the costs as defined.  These financial measures should not be viewed as a substitute for, or superior to, operating earnings, net earnings or net cash flows provided by operating activities (each as defined under GAAP), the most directly comparable GAAP measures, as a measure of the Company’s operating performance.

Pursuant to the requirements of Regulation G of the Exchange Act, we are providing the following tables that reconcile the above mentioned non-GAAP financial measures to the most directly comparable GAAP financial measures:
