Fiscal Third Quarter 2020 Information

•Won 35 manufacturing programs during the quarter representing an expected $252 million in annualized revenue when fully ramped into production

•Trailing four quarter wins total an expected $868 million in annualized revenue when fully ramped into production

Todd Kelsey, President and CEO, commented, “I am incredibly proud of our global Plexus team as they managed through the complexities arising from COVID-19 while delivering record quarterly revenue of $857 million and GAAP diluted earnings per share of $1.20. This strong performance led to GAAP operating margin of 5.3%, our best quarterly margin result in three years. Further, our team overcame the challenges of the pandemic to deliver exceptional manufacturing wins of $252 million annualized when fully ramped into production. In addition to traditionally strong wins from our existing customers, our team’s innovative virtual business development efforts resulted in a meaningful number of new target customer wins. Our global team’s demonstrated ability in providing superior execution continues to position us for future growth."

Patrick Jermain, Executive Vice President and CFO, commented, “During the fiscal third quarter, we delivered a return on invested capital of 12.9%. This equates to an economic return of 410 basis points above our weighted average cost of capital, creating solid shareholder value. A combination of exceptional operating performance and improved working capital generated this return, an improvement of 150 basis points over the previous quarter. The increase in fiscal third quarter revenue and improvements in our inventory management contributed to an eight day sequential improvement in our fiscal third quarter cash cycle days. We generated $37 million of free cash flow during the quarter, exceeding our net income.”

Mr. Jermain continued, “We are well-positioned with a strong balance sheet. Cash of approximately $300 million was sequentially higher by $73 million while our short-term debt increased $38 million. In May, we executed a 364-day term loan with several of our credit facility banks. We secured $138 million through this offering. With the proceeds, we repaid existing borrowing under our revolving credit facility. At the end of the fiscal third quarter, there was no outstanding borrowing under this facility, therefore allowing us the full use of the $350 million facility.”

Mr. Kelsey continued, “While we expect continued end market volatility, our aggregate demand is anticipated to remain strong in our fiscal fourth quarter. As a result, we are guiding revenue in the range of $850 to $890 million. At this anticipated revenue level, coupled with expected sustained solid operating performance, we are guiding GAAP diluted EPS in the range of $1.05 to $1.20. In providing this guidance, we have taken into consideration known constraints with the global supply chain and workforce challenges that could occur due to COVID-19. However, our guidance assumes no large scale closures of our facilities, or those of our suppliers or customers, due to COVID-19, nor does it assume that the COVID-19 outbreak will materially impact end markets beyond what has already occurred.”

Mr. Kelsey concluded, “As we move into the early part of fiscal 2021, we anticipate certain COVID-related demand to moderate in advance of the anticipated benefit of growth from new program ramps later in the year. Despite the known impacts related to COVID-19, we see a path to continued strength in operating performance throughout fiscal 2021.”

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 with 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 non-recurring items that 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%. Plexus defines ROIC as tax-effected annualized adjusted operating income divided by average invested capital over a four-quarter period for the fiscal third quarter. Invested capital is defined as equity plus debt and operating lease liabilities, less cash and cash equivalents. Plexus' weighted average cost of capital for fiscal 2020 is 8.8%. ROIC for the fiscal third quarter less Plexus' weighted average cost of capital resulted in an economic return of 4.1%.

Plexus defines free cash flow as cash flows provided by operations less capital expenditures. For the three months ended July 4, 2020, cash flows provided by operations of $47.1 million, less capital expenditures of $10.5 million, resulted in free cash flow of $36.6 million. For the nine months ended July 4, 2020, cash flows provided by operations of $92.5 million, less capital expenditures of $41.2 million, resulted in free cash flow of $51.3 million.

These regulations impacted the treatment of foreign taxes paid.

PLEXUS CORP. Safe harbor and fair disclosure statement Any statements made during our call today and information included in the supporting material that is not historical in nature, such as statements in the future tense and statements that include "believe," "expect," "intend," "plan," "anticipate," and similar terms and concepts, are forward-looking statements. Forward-looking statements are not guarantees since there are inherent difficulties in predicting future results, and actual results could differ materially from those expressed or implied in the forward- looking statements. For a list of factors that could cause actual results to differ materially from those discussed, please refer to the Company’s periodic SEC filings, particularly the risk factors in our Form 10-K filing for the fiscal year ended September 28, 2019, as supplemented by our Form 10-Q filed with the SEC on May 8, 2020, and the Safe Harbor and Fair Disclosure statement in yesterday’s press release. Plexus provides non-GAAP supplemental information, such as ROIC, economic return, and free cash flow, because those measures are used for internal management goals and decision making, and because they provide 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 earnings per share, to provide a better understanding of core performance for purposes of period-to-period comparisons. For a full reconciliation of non-GAAP supplemental information please refer to yesterday’s press release and our periodic SEC filings. 2
