Fiscal Third Quarter 2018 Information

• Won 45 manufacturing programs during the quarter representing $202 million in annualized revenue when fully ramped into production
• Trailing four quarter manufacturing wins total $828 million in annualized revenue when fully ramped into production
• Purchased $56.7 million of our shares at an average price of $59.81 per share under our existing share repurchase program

Todd Kelsey, President and CEO, commented, “Our fiscal third quarter revenue of $726 million marks the fourth consecutive quarter of record revenue and a 17% increase from the comparable quarter last fiscal year.  We delivered higher than anticipated revenue associated with new program ramps while navigating a challenging supply chain environment, resulting in lower than expected operating margin.  Within the quarter our teams continued their strong wins performance by exceeding $200 million in manufacturing wins and achieving record engineering wins, positioning us for meaningful growth.”

Patrick Jermain, Senior Vice President and CFO, commented, “During the fiscal third quarter, we continued to execute on our previously disclosed capital allocation strategy.  In addition to the $280 million of offshore cash brought back to the U.S. in the fiscal second quarter, we repatriated approximately $100 million during the fiscal third quarter.  We deployed the cash by investing in facilities and working capital, repurchasing approximately $57 million of shares under our repurchase program and reducing our borrowing.”  Mr. Jermain continued, “In June, we successfully refinanced $150 million of the $175 million of senior notes that matured, reducing our debt by $25 million and lowering our borrowing costs given the favorable fixed interest rates. We anticipate repatriating an additional $50 million during the fiscal fourth quarter, which would result in more than $400 million repatriated for fiscal 2018.”

Mr. Kelsey continued, “Looking ahead to the fiscal fourth quarter, we expect our revenue growth trajectory to continue due to our wins performance and improved end markets.  As a result, we are establishing revenue guidance of $735 to $775 million.  At this revenue level, we would exceed our 12% annual revenue growth goal for the fiscal year.  We are guiding fiscal fourth quarter GAAP diluted EPS in the range of $0.82 to $0.92.  With performance in this range we would expect to deliver record operating profit.”

Mr. Kelsey concluded, “As we look forward to fiscal 2019, we are optimistic we will achieve further revenue growth, while also improving our margin performance, as we gain operating and fixed cost leverage from programs that are fully ramped into production.  Further, we anticipate that improved operating efficiency, in conjunction with our share repurchase program, will result in meaningful EPS leverage.”

Non-GAAP Supplemental Information
Plexus provides non-GAAP supplemental information, such as ROIC, Economic Return, and free cash flow, because such measures are used for internal management goals and decision making, and because they provide management and investors additional insight into financial performance.  In addition, management uses these and other non-GAAP measures, such as adjusted operating income, adjusted operating margin, adjusted net income and adjusted diluted EPS, to provide a better understanding of core performance for purposes of period-to-period comparisons.  Plexus believes that these measures are also useful to investors because they provide further insight by eliminating the effect of items, such as the one-time, non-executive employee bonus paid in the second quarter of fiscal 2018 and the transitional effects of the U.S. Tax Cuts & Jobs Act (“U.S. Tax Reform”), that are not reflective of continuing operations.  For a full reconciliation of non-GAAP measures to comparable GAAP measures, please refer to Non-GAAP Supplemental Information and the attached Non-GAAP Supplemental Information Tables.

ROIC and Economic Return
ROIC for the fiscal third quarter of 2018 was 15.9%. The Company defines ROIC as tax-effected annualized adjusted operating income divided by average invested capital over a four-quarter period for the third quarter.  Invested capital is defined as equity plus debt, less cash and cash equivalents.  The Company’s weighted average cost of capital for fiscal 2018 is 9.5%.  ROIC for the quarter less the Company’s weighted average cost of capital resulted in an economic return of 6.4%.

Free Cash Flow Calculation
The Company defines free cash flow as cash flows provided by operations less capital expenditures.  For the three months ended June 30, 2018, cash flows provided by operations was $38.6 million, less capital expenditures of $22.9 million, resulting in free cash flow of $15.7 million. For the nine months ended June 30, 2018, cash flows provided by operations was $41.4 million, less capital expenditures of $52.0 million, resulting in negative free cash flow of $10.6 million.

(2	)	During Q1F18, $124.5 million of tax expense was recorded as a result of the enactment of U.S. Tax Reform.  The results for the three months ended June 30, 2018 and March 31, 2018, were not impacted by U.S. Tax Reform as the provisional amounts recorded in Q1F18 remain unchanged.
(3	)	For the nine months ended June 30, 2018, the total weighted average number of potentially-dilutive shares was 0.9 million. However, these shares were not included in the computation of GAAP diluted net loss per share since to do so would have decreased the loss per share.  No shares were excluded in any of the other reported periods.
