Fiscal Third Quarter 2019 Information


•	Won 23 manufacturing programs during the quarter representing $227 million in annualized revenue when fully ramped into production


•	Trailing four quarter manufacturing wins total $938 million in annualized revenue when fully ramped into production


•	Purchased $44.4 million of our shares at an average price of $56.61 per share under our existing share repurchase program

Todd Kelsey, President and CEO, commented, “We achieved record revenue of $800 million in the fiscal third quarter, a 10% increase from the comparable quarter last year. We delivered revenue at the high end of our guidance range through successful program ramps and healthy demand in our differentiated end markets. GAAP EPS of $0.81 was in line with our expectations and met the midpoint of our guidance range.”

Patrick Jermain, Executive Vice President and CFO, commented, “During the fiscal third quarter, we continued to execute our capital allocation strategy by repatriating approximately $37 million of offshore cash. Since the enactment of U.S. tax reform in our last fiscal year, we have brought back over $500 million. We repurchased approximately $44 million of our shares during the fiscal third quarter, which was primarily funded with repatriated cash.”

Mr. Jermain continued, “On May 15, 2019, we refinanced our credit facility to take advantage of favorable pricing and improve our financial covenants. In addition, the maximum commitment under the credit facility was expanded to $350 million, with the potential to increase it by an additional $250 million. The maturity of the credit facility was extended to May 2024. The amended facility provides us with additional borrowing capacity and flexibility in anticipation of future growth.”

Mr. Kelsey continued, “Looking ahead to the fiscal fourth quarter, I am encouraged by the anticipated performance of our sectors that feature highly complex products and demanding regulatory environments. We expect new program ramps and stable end markets within these sectors to soften the impact of a meaningful demand reduction in the Communications sector. Therefore, we are guiding fiscal fourth quarter revenue in the range of $760 to $800 million, which is consistent with the range we provided for our fiscal third quarter guidance. We expect continued improvement in operating performance and, as a result, we are guiding GAAP EPS in the range of $0.81 to $0.91. This excludes any non-recurring charges as a result of addressing revenue declines in our Communications sector.”

Mr. Kelsey concluded, “Looking forward to fiscal 2020, we expect another year of revenue growth as we continue to deliver meaningful wins performance and ramp new programs in our differentiated markets of Healthcare/Life Sciences, Aerospace/Defense and Industrial/Commercial. In addition, I am pleased with the readiness of our state of the art facilities in which we invested during fiscal 2019, as well as the progress of our productivity initiatives. We anticipate a combination of these efforts will result in operating margin expansion and EPS leverage during fiscal 2020.”

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 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 continuing transitional effects of the U.S. Tax Cuts & Jobs Act (“U.S. Tax Reform”) and the one-time, non-executive employee bonus paid in the second quarter of fiscal 2018, which are not reflective of continuing operations. For a full reconciliation of non-GAAP measures to comparable GAAP measures, please refer to the attached Non-GAAP Supplemental Information Tables.

ROIC and Economic Return

ROIC for the fiscal third quarter was 12.9%. The Company defines ROIC for the fiscal third quarter as tax-effected annualized adjusted operating income divided by average invested capital over a four-quarter period. Invested capital is defined as equity plus debt, less cash and cash equivalents. The Company’s weighted average cost of capital for fiscal 2019 is 9.0%. ROIC for the fiscal third quarter less the Company’s weighted average cost of capital resulted in an economic return of 3.9%.

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 29, 2019, cash flows provided by operations were $41.5 million, less capital expenditures of $20.0 million, resulting in positive free cash flow of $21.5 million. For the nine months ended June 29, 2019, cash flows provided by operations was $7.0 million, less capital expenditures of $74.6 million, resulting in negative free cash flow of $67.6 million.

(1) The Company calculates cash cycle as the sum of days in accounts receivable, contract assets and days in inventory, less days in accounts payable and days in cash deposits. On September 30, 2018, the Company adopted Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue Recognition (Topic 606). For the three months ended June 29, 2019 and March 30, 2019, cash cycle days include contract assets and an associated reduction in inventory. As the guidance was adopted using a modified retrospective approach, no impact to prior periods was required to be recognized.

(2)	During the three months ended December 29, 2018, non-recurring tax expense of $7.0 million was recorded in accordance with new regulations issued in November 2018 under U.S. Tax Reform. These regulations impacted the treatment of foreign taxes paid. During the nine months ended June 30, 2018, $124.5 million of tax expense was recorded as a result of the enactment of U.S. Tax Reform. The results for the nine months ended June 30, 2018, were not impacted by U.S. Tax Reform as the provisional amounts recorded in the three months ended December 30, 2017, remained unchanged at that time.
(3)	For the nine months ended June 30, 2018, the total weighted average number of potentially-dilutive securities was 0.9 million. However, these securities 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.
