rapidly as a major supplier of solar wafers which we estimate accounts for more
USA than 14% of sales. Direct polysilicon sales to customers (mostly solar companies)
Solar are also a significant percentage of revenue at over 20%, but we estimate semi

Slicing a better wafer
MEMC has been a leader in the semi wafer business since 1959, but has emerged
rapidly as a major supplier of solar wafers which we estimate accounts for more
than 14% of sales. Direct polysilicon sales to customers (mostly solar companies)
is also a significant percentage of revenue at over 20%, but we estimate IC sales
still represent two-thirds of revenues. We believe that combined sales of solar
wafers and poly to solar will continue to be a high growth area for MEMC.
As an experienced tier 1 polysilicon producer, WFR has been able to increase
market share due to economies of scale, industry know-how and top talent. The
company has been at the helm of technological innovation and has led capacity
expansion for four decades. We believe WFR is well positioned to capitalize on the
extremely tight polysilicon market that should last through 2009.
Premium poly player
WFR benefits from WFR has benefited from being an experienced tier-1 polysilicon producer during
experience and increased the early growth stage of the solar industry. As one in a small group of
market share of
established polysilicon producers, WFR has been able to build out its solar
polysilicon to 14% in
2007 capabilities while capturing market share and positioning itself at the helm of
technological innovation. In 2007 WFR had 14% market share of the polysilicon
market, up from 12% and 13% in 2005 and 2006, respectively. Economies of
scale and technological know-how have led WFR to this incumbent position.

MEMC - silicon since 1959
Silicon since 1959 Since its founding in 1959, Missouri based MEMC Electronic has enjoyed a long
and prosperous 50 year history partaking in the design, development and sale of
its silicon wafers to the integrated circuit market and solar industry, encountering
few impediments along the way. The well positioned silicon and wafer
heavyweight finds itself strategically straddling the saturated $1 trillion
integrated circuit market and the blooming $18 billion solar industry providing
each with the necessary poly. Although the company has seen mostly success
over the decades, along with the rest of the electronic/integrated circuit and
semiconductor industries, MEMC faced major setbacks just before the turn of the
century due to overcapacity and steep drop off in demand. Subsequent to
surviving the turmoil, today they face a new challenge of meeting increasing
demand for poly from solar.
Brief history
Defining industry MEMC established itself as a technological leader not long after its inception with
standards much of its fundamental research coming about during the 1960’s. The research
was so landmark that much of the work done at the time still remains an industry
standard today such as the chemical-mechanical polishing process (CMP),
epitaxial (Epi) deposition, and the discovery and use of zero dislocation silicon
crystals.
MEMC made a name for These technological innovations allowed the company to grow swiftly alongside
itself during the semi the booming semiconductor industry in the 1970’s and 1980’s as MEMC met
boom in the 70’s and 80’s soaring demand for smaller and faster integrated circuits with further
technological advancement including the development of the 125mm, 150mm,
and 200mm diameter wafers. The growth required an increase in capacity which
was made possible through the unveiling of new manufacturing facilities in Kuala
Lumpur, Malaysia and Utsonomiya, Japan.
1995 IPO raised over The 1990’s marked a period of momentous growth for MEMC as the company
$440 million, just before raised over $440 million in capital during its IPO in 1995. During that same year,
the overcapacity in 1998 MEMC decided to purchase the granular polysilicon manufacturing facility that
they had been using from Abermarle Corporation and renamed the plant
Pasadena. Despite its good times, MEMC suffered a crippling setback in 1998 and
1999 as global overcapacity and demand drop off hurt it financially.
With a new outlook and goal to reclaim industry leadership following these tough
times, the company appointed Nabeel Gareeb as President and CEO of MEMC and
looked to him to reinvent its business strategy and increase market share. Prior
to joining MEMC, Mr. Gareeb held the title of COO at International Rectifier
Corporation, a leading power semiconductor company, for over 10 years.

Products and technology
MEMC certainly fits the description of a pioneer as it boasts a rich portfolio
comprised of over 600 patents globally with an additional 300 on file for
application. Customers can take comfort in the consistent supply of fresh
innovation as MEMC was the first merchant manufacturer of silicon wafers, the
first to commercially produce 100mm, 125mm, 150mm and 200mm diameter
wafers, and the first to create a patented defect-free wafer, among many other
industry firsts.
MEMC meets customers’ MEMC meets its customers’ strict specifications and offers vast flexibility since
specifications and offers the application of the wafer is unique to each customer. In 1990, the company
flexibility filled orders for 1,200 different wafer specifications. This figure has stretched to
2,200 in 2006 as integrated circuit and electronics manufacturer needs continue
to advance. For this reason, the company makes three different types of wafers
available for purchase: prime polished, epitaxial, and test grade. Choice only
begins there as the customer must then decide on the composition, level of
purity, crystal and electrical properties of the wafer. MEMC continues to strive
toward increased wafer yield while simultaneously reducing the thickness of the
wafers to benefit electronics manufacturers. MEMC’s primary product offering is
the polished wafer. After growing their pure crystalline silicon wafer from granular
polysilicon, it undergoes their CMP process to eliminate all surface defects which
results in a smooth, mirror-like wafer.
Company has begun to Silicon wafers make up the foundation of most solar cells which is why MEMC has
produce 156mm wafers devoted more of its focus to the solar industry. The company has begun to
for solar application produce solar grade, 156mm wafers as it seeks to facilitate the solar industry’s
road to grid parity. Production of the wafer is only the first step that the company
has taken in what promises to be a strong relationship in the future between
MEMC and the solar industry as they expect to extend their knowledge of
polysilicon and wafer production to the solar industry to spur innovation
throughout, beginning with MEMC solar grade wafers.
SOI allows for more Much of the company’s research is devoted toward forward progress in the
complex surface designs research and development of new materials. Silicon-On-Insulator (SOI) is a novel
base material for the fabrication of chips that increases the functionality without
requiring large amounts of money for changes in fab equipment. This tri-layer
wafer allows for more complex circuit design and ultimately leads to faster
operation at lower voltages.
Chemical-mechanical MEMC’s innovation is not only limited to the end product. In 1962, MEMC the
polishing process pioneered chemical-mechanical polishing process, which is still an industry
developed in 1962 is still standard today. The process is a combined effort between a chemical corrosive
industry standard today
used to weaken the silicon and a mechanical polishing pad to remove any surface
defects, leaving a flat, smooth, mirror-like surface.
Through the years, silicon manufacturers have spent much time and money
ensuring that the wafers are not only functional, but that they enhance the user’s
yield. Most wafer manufacturers use a conventional method of internal gettering
(the process of moving impurities to the bulk) which requires long heating and
cooling periods followed by a third, growth step which leads to variation in wafers
due to high sensitivity to oxygen concentration. MEMC developed and patented a
breakthrough Rapid Thermal Process (RTP) named Magic Denuded Zone (MDZ),
which allows them to bypass the long heating period and control oxygen related
complications by heating the wafer to over 1200°C in a matter of seconds,
followed by a slightly lengthier, more controlled cooling period. MDZ gives
manufacturers a newfound freedom in working with the silicon while also
reducing processing cost to the manufacturer.

Execution misfires present opportunity
Lingering concern of Incidents that have occurred recently include a fire and an equipment failure in
stolen talent may point to Merano, a tropical storm, and a chemical buildup in Pasadena. These are some of
cause of execution
the events that have occurred over the course of the last year or so that have
problems
assisted WFR’s shares in gaining membership to the 52-week low club. Are these
execution missteps purely bad luck? Or are they symptoms of something more
chronic? Likely the answer is a little of both. There is concern that the solar wafer
industry may be stealing talent from some of the established polysilicon and
wafer makers, especially in Asia where there are over 30 new polysilicon
production projects underway. MEMC has been a casualty of this migration east.
Figure 8
MEMC incident report since 2005
Date Incident
8/05/08 The company reported that it has taken safety precautions in preparation for heavy weather associated with
Tropical Storm Edouard at its Pasadena, Texas facility. As part of these precautions, the company has
moderated operations in various areas of the facility, which is currently anticipated to have approximately a
two day effect on polysilicon production.
4/03/08 MEMC reported it experienced accelerated buildup of chemical deposits inside the new expansion unit
("Unit 3") at its Pasadena, Texas facility. These buildups occurred multiple times, and each instance required
downtime of several days for premature maintenance to clean and re-stabilize the unit. The company also
delayed the remaining maintenance (from the prior quarter) on the existing units ("Unit 1" and "Unit 2")
waiting for Unit 3 to stabilize, but eventually had to perform the maintenance on Unit 2.
4/29/08 Pasadena, Texas -- a transfer line from a transport vehicle developed a leak and caused a release of STF, a
raw material gas used in the manufacturing process. The leak was quickly contained by the on-site
emergency response team and the flow of material was stopped.
7/23/08 The company said it suffered a "premature failure of a relatively new heat exchanger" at its Merano, Italy
facility, while a loose pipe fitting caused a fire at its Pasadena, Texas facility during the quarter.
9/04/07 A construction incident caused by one of its electrical subcontractors working on the Pasadena, Texas,
polysilicon facility expansion resulted in a power outage to the entire site. Although the power was
eventually restored later the same day, the unplanned and abrupt shutdown of high temperature and pressure
chemical operations caused considerable complications. The facility is now in the late stages of recovery, but
the abrupt nature of this incident, combined with the rain and thunderstorms in Pasadena, Texas over the last
few days, has hampered the facility's ability to recover operations expeditiously. This disruption has also
caused the on-going polysilicon expansion project at the site to be additionally delayed.
9/26/05 Pasadena, Texas -- The company reported that its employees in the Pasadena area are safe and that business
resumption activities had begun on Sunday. The facility itself sustained no major damage from hurricane
Rita. Prior to the hurricane, MEMC had safely evacuated employees from this facility.

Market is pricing in a lack The bad news for the stock is that the market generally fears the unknown, and
of talent and any the unknown in this case is how much was due to lack of talent in key positions
improvements will boost
and how much was due to uncontrollable events that are inevitable in the
value of the stock
business of manufacturing polysilicon. The good news for investors is that the
market is pricing in a lack of talent. Placing the right talent in key positions is a
problem that senior management can address and correct (and in some cases
WFR has already made key personnel changes). We are confident that execution,
and therefore the value of the stock, will improve at MEMC.
Last 2 quarters of misses In WFR’s last two quarters, the company missed Street EPS estimates by 9% in
tarnish a long history of 2Q and 1% in 1Q. Previously, the company had beat earnings estimates for 9

the cycle has been

bottom of the cycle in the highly cyclical semiconductor industry. While all of the
evidence points to a bottom, the important question is will demand recover soon?
Or will we stay at the bottom for a prolonged period of time…

Signs of a semi rebound?
Multiple expansion would We believe that semi demand may be showing signs of life, as recent reports
be justified if we see the indicate an increase in wafer sales. Applied Materials (AMAT – NR) recently
semi cycle reverse
posted strong Q2 results and indicated a 30% increase in equipment orders from
foundries and DRAM. This indicates some hope (but not proof) that a recovery
may come sooner rather than later. As MEMC increases its capacity to produce
polysilicon and 300mm wafers, we need to see a return to capital spending by
the chip makers, DRAM makers and foundries. A confirmed increase in demand
would justify multiple expansion from our 15x number.
Anecdotal evidence of Besides AMAT’s favorable comments on demand, we have heard other
semi recovery incrementally positive comments from our channel checks and from industry
associations. SEMI reported this month that global silicon wafer shipments were
2,303 million square inches (MSI) in 2Q08. This is up 4.6% Y/Y from 2,201 MSI
in 2Q07, and up 6.5% Q/Q from 2,163 MSI in 1Q08. According to Kazuyo Heinink
who is the chairwoman of SEMI and also, more importantly for investors, Vice
President for New Product Marketing at MEMC, “this growth was mainly attributed
to 300mm” where MEMC is growing to over 700k wafers per month in 2010 from
under 400k per month by year end 2008.
Setting the bar too low to miss
MEMC reduced FY08 MEMC lowered its full year 2008 guidance for both top and bottom line by $150
guidance to compensate to $175 million and $0.30 to $0.50 per share respectively to compensate for a

guidance was for earnings of $4.50 to $4.60/share on annual revenues of $2.4 to
$2.5 billion. Revised guidance for the year is $2.25 to 2.35 billion in revenues
and EPS of $4.00 to $4.30/share. In tandem with its lower guidance, the
company scheduled a mid-quarter progress update for September 2nd. We

believe that the progress update will be positive and act as a positive catalyst for
the stock leading into 3Q results.
Growing Capacity and Revenue
Growth in market share WFR’s growth in market share has been reflected by its growth in polysilicon
reflected by growth in capacity and revenue. The compnany has undergone an aggressive capacity

A strong financial position We believe WFR is well positioned to weather the solar shake-out that we see
will protect WFR from looming due to its strong cash generating capabilities and its robust balance
looming solar shake-out
sheet. We believe WFR’s strong financial position will act as a protective shield
during difficult operating environments as well as enable the company to make
strategic investments and acquisitions while others may be sidelined or
susceptible to takeovers themselves as the result of a lack of cash.

Possibility for earnings Strong revenue growth, resulting from increased volume, coupled with continued
upside and margin cost improvements should lead to widening margins in the near-term. Following
expansion could come
this fruitful near-term period we believe growth and expansion will level off due
from a strategic
acquisition to the aforementioned threats to polysilicon producers and transitions taking
place in the industry. We believe margins and growth will be sustained at
attractive, albeit lower, levels during this period; however, we believe WFR will be
uniquely positioned in the solar industry at this point due to its strong financial
position. We see the possibility for earnings upside and continued margin
expansion resulting from a strategic acquisition made before WFR reaches this
phase of slowing growth.

Spending it wisely
There may be considerable upside to WFR’s valuation pending management’s use
of the company’s substantial free cash flow. Although the company has been
proactive in buying back shares and returning value to shareholders, we would
applaud some cash being returned to shareholders in the form of a dividend,
which the board has been considering. A value creating acquisition such as a
solar wafer maker would also improve our outlook as the company could apply its
years of semi wafer technology to improve the quality and therefore margins on
solar wafers.
What to do with all that cash
WFR is sitting on a pile of cash, with $1.1 billion in cash and equivalents alone at
the end of 2Q08. Why aren’t they giving out that cash right now? Well most of
the current board members are survivors of the late 90’s and early 00’s when
cash was tight due to the tech implosion. In our model we forecast the company
reaching in excess of $2.4 billion in 2012 (assuming no dividends).
Still plenty of buyback to The company already has a share buyback program in place with a board
be done authorized amount of $1 billion which was approved in 2Q. This is twice the
amount of the $500 million which was initially approved in May 2007. As of June
30, 2008 the company had already bought back 4.04 million shares for a total of
$270 million.
Share buyback program is The possibility of a dividend has also been discussed at MEMC’s board meetings,

amount, but could act as a catalyst as the company would be exposed to an
additional class of investor that is either required or compelled to own dividend
paying stocks.
Competition heating up in solar, cooling in semi
New entrants in poly face high barriers to entry as high capital requirements,
technical barriers, equipment procurement and long lead times make it difficult
to gain a foothold. MEMC’s competitors include Hemlock, SUMCO, Soitek, Wacker,
LDK, Shin-etsu, Covalent, LG Siltron and REC.
Vertical integration in solar
MEMC may be shopping MEMC is already integrated from poly to wafer on the semiconductor side of its
for a cheap wafer maker business, however on the solar side of the house the company outsources its
wafering to 3rd parties. In 2009 the company plans to bring its solar wafering in-
house, retaining more margin power in the process. More importantly, the
company’s R&D shop is chomping at the bit to apply years of extensive research
in semiconductor wafer enhancement technology to solar. Management is
confident that they can improve margins on solar wafers by improving the watts
per wafer, the basis of their pricing on solar wafer sales contracts.
The decision to bring solar wafering in-house has launched what we believe is a
global search for a wafer maker. Most wafer makers are located in Asia and
include companies like LDK (LDK US), M. Setek, Renesola (SOL US), and Sino-
American Silicon. We also would not rule out the eventual possibility of forward
integration into the cell manufacturing segment if they develop a process
whereby cell architecture is designed around a proprietary MEMC wafer.
We believe that WFR is well positioned to capitalize on the opportunity that the
demand for solar energy presents. The need for alternative sources of energy has
never been greater. The EIA estimates that world marketed energy consumption
12 george.kotzias@us.calyon.com 19 August 2008
13. Section 3: Spending it wisely WFR - BUY
will grow by 110% over the 2000 to 2050 period. This onslaught of growth is
mainly attributable to strong growth in energy demand among non-OECD
nations.

Need for energy A need for alternative fuel sources brought on by this growth in energy demand
alternative exacerbated has been exacerbated by the steady rise in carbon dioxide emissions as well as in
by rise in CO2 emissions

Technical innovator
Through its progressive in-house R&D program and a series of acquisitions, WFR
has been able to maintain its edge as a technological innovator in the ever
changing and performance demanding polysilicon industry. Fundamental research
conducted in the 1960’s led to the zero-dislocation silicon crystals that allowed
WFR to grow in-line with the booming semiconductor industry in the 1970’s and
1980’s.

Since WFR’s entrace into the solar industry in 2006 the company has focused on
offering higher grade polished wafers.
The company offers three WFR offers three general categories of wafers that include prime wafers, epitaxial
different types of wafers wafers and test / monitor wafers. Prime wafers are polished, highly refined pure
including prime, epitaxial,
wafers with an ultraflat and ultraclean surface. WFR’s premium brand prime
and test grade
wafer is called the OPTIA wafer. The OPTIA wafer is a defect-free crystalline
structure that incorporates patented technologies and processes, such as the
Magic Denuded Zone, which increases yield by drawing impurities away from the
wafer surface.
Figure 19
Wafer category offerings
Type Characteristics Premium brand name
Prime wafers Polished, highly refined, ultraflat & clean surface OPTIA
Epitaxial wafers Superior isolation between circuit elements AEGIS
Source: Company reports
Epitaxial wafers have a thin silicon layer grown on the polished surface of the
wafer and provide superior isolation between circuit elements versus a polished
wafer. WFR’s proprietary epitaxial wafer, AEGIS, also incorporates Magic Denuded
Zone and has a thin eqitaxial layer grown on a standard starting wafer that
elimates harmful defects on the wafer surface.
WFR also offers test / monitor wafers for the testing of semiconductor fabrication
lines and processes. These wafers are produced from the portion of silicon ingot
that does not meet certain specifications but are similar to prime wafers in
regard to cleanliness and flatness, in some cases.
Increasing GOI yield The company sells higher grade polished wafers under their trademark Advanta.
The wafer offers customers a cost effective product that includes a higher yield
and better performance for integrated circuits. Advanta is aimed at next
generation integrated circuits and has low levels of crystal originated pits (COPs)
on the surface while also boosting performance with higher gate oxide integrity
(GOI) of 81.8. For even better performance, the company’s trademark Optia
wafer is entirely COP free and has a superior GOI of 98.6 which makes it an ideal
long term solution for advanced integrated circuits.

MEMC wafers increase Manufacturers of advanced semiconductor devices demand greater functionality
functionality through more complex circuits. As the size of the circuit is reduced, insufficient
electrical isolation between the elements becomes a problem. MEMC offers its
epitaxial wafers as the solution. Epitaxial wafers were created to increase the
reliability of the semiconductor device and provide higher efficiency by growing a
thin, single crystal silicon layer above the polished surface having different
electrical and compositional properties. Their trademark epitaxial wafer, Aegis, is
a cost effective alternative to the prime polished wafer with the difference lying
in the COP free zone which only exists in the epi layer of the wafer rather than
the entire bulk.
Weaker semi demand increases solar appeal
There is excess memory and processor capacity at the enterprise level due to the
emergence of virtualization and improved software efficiency. Some estimates
suggest that 65% or more of existing capacity is idle, as software efficiency has
reduced the strain on memory and processor capacity. The internet has allowed
companies to manage their global server network much more efficiently, as over-
utilized servers can communicate with underutilized or idle servers and share the
computing load.
The in-house advantage
WFR produces granular MEMC puts itself at a huge advantage against its competitors by making its own
polysilicon in-house granular polysilicon to use as the raw material for wafer manufacture. Granular
polysilicon processing is a far more efficient process that supports higher growth
yield. The continuous throughput is an improvement to the Siemens process. In
the more common and lower barrier to entry Siemens process, a high purity
silicon rod receives exposure to trichlorosilane gas at high temperatures
exceeding 1100°C. The chemical reaction causes additional silicon from the gas
to be deposited onto the rod. MEMC uses the more efficient fluidized bed reactor
(FBR) process to produce its granular polysilicon which has helped lower material
costs in its wafer production. The FBR process makes this possible by consuming
80% - 90% less energy while allowing for greater yield, productivity and product
purity.
