NEENAH, WI, January 7, 2013 -- Plexus Corp. (NASDAQ: PLXS) today announced
that it expects to report revenue and earnings below the guidance provided for
the fiscal first quarter of 2013. Revenue is expected to be approximately
$531 million with diluted earnings per share expected to be in the range of
$0.45 to $0.47, excluding any restructuring charges. The original fiscal
first quarter guidance was revenue of $550 to $580 million with diluted
earnings per share of $0.50 to $0.55, excluding any restructuring charges.

Dean Foate, President and CEO, commented, "While manufacturing demand softened
across all of our sectors during the quarter, in particular we did not
experience the typical demand-pull of products in our
Networking/Communications sector in the final few weeks of the quarter. As a
consequence, our Networking/Communications sector revenue was substantially
below our expectations for the quarter and accounted for the majority of the
shortfall to our original guidance."

These results are preliminary and therefore subject to the Company's
completion of its fiscal first quarter closing and review procedures. The
Company will report final results on January 16, 2013 and will host a
conference call on January 17, 2013 at 8:30 a.m. Eastern Time to discuss these
results. The call can be accessed at 1-800-927-0469 with confirmation:

periods; the risk that our agreement with Kontron does not result in the
revenues or margins anticipated by us; our ability to secure new customers,
maintain our current customer base and deliver product on a timely basis; the
particular risks relative to new or recent customers or programs, which risks
include customer and other delays, start-up costs, potential inability to
execute, the establishment of appropriate terms of agreements, and the lack of
a track record of order volume and timing; the risks of concentration of work
for certain customers; our ability to manage successfully a complex business
model characterized by high customer and product mix, low volumes and
demanding quality, regulatory, and other requirements; the risk that new
program wins and/or customer demand may not result in the expected revenue or
profitability; the fact that customer orders may not lead to long-term
relationships; the effects of shortages and delays in obtaining components as
a result of economic cycles or natural disasters; the risks associated with
excess and obsolete inventory, including the risk that inventory purchased on
behalf of our customers may not be consumed or otherwise paid for by the
customer, resulting in an inventory write-off; the weakness of areas of the
global economy and the continuing instability of the global financial markets
and banking system, including the potential inability of our customers or
suppliers to access credit facilities; the effect of changes in the pricing
and margins of products; the effect of start-up costs of new programs and
facilities, such as our announced plans to replace facilities in Romania and
the United States, and other recent, planned and potential future expansions;
increasing regulatory and compliance requirements; possible unexpected costs
and operating disruption in transitioning programs; raw materials and
component cost fluctuations; the potential effect of fluctuations in the value
of the currencies in which we transact business; the potential effects of
regional results on our taxes and ability to use deferred tax assets; the
potential effect of world or local events or other events outside our control

terrorism and weather events); the impact of increased competition; and other
risks detailed in the Company's Securities and Exchange Commission filings
(particularly in Part I, Item 1A of our annual report on Form 10-K for the
