LETTER TO THE SHAREHOLDERS

"The strength of Graham's brand, our skilled team, and the measures we are
taking to improve our business gives us confidence in our outlook."

Dear Fellow Shareholders,


                                       2



Fiscal 2005 was a year of change and progress for Graham Corporation. In the
short few months that I have been here, I have had the opportunity to personally
validate what you likely already know:

     -    Our brand carries significant weight with our customers around the
          world.

     -    Our engineering know-how and solutions-oriented problem solving is
          well respected in the engineering community.

     -    We have a strong position in the global oil refining, electrical power
          generating and chemical processing markets.

     -    Our manufacturing expertise is relied on heavily by our customers for
          the consistency and reliability we provide with our products.

     -    We have an excellent, talented team at Graham.

These qualities provide a solid foundation from which we can face a more
challenging, yet opportunity-filled future.

In fiscal 2005, sales increased 10% to $41.3 million. The year was a tale of two
halves. In the first half of the year, our primary markets were sluggish, and we
were still feeling the effects of higher raw material prices, such as steel, in
fixed price contracts that were being built. In the latter half of the year, we
tightened the controls necessary to mitigate the material cost escalations, and
we began to see new orders for vacuum systems and condensers pick up as a
growing demand in our key markets had translated into some sizable orders. Based
on the current level of inquiry, we anticipate this trend continuing through
2006 and into 2007.

Income from continuing operations was $296 thousand, or $0.17 per diluted share.
This was a marked improvement from a loss of $832 thousand, or $(0.51) per
diluted share, in fiscal 2004. The improvement reflected the leverage we gained
from higher sales, increased selling prices and improved product mix. We expect
margins will improve as sales improve. However, I believe we have the
opportunity to strengthen our ability to contribute to the bottom line by
improving operational efficiencies and implementing automation through
information technology throughout our operations.

CONVERGING REVENUE DRIVERS

Our markets have significantly improved over the last year as a result of
several factors:

     -    Global growth, especially in Asia, has raised the demand for oil and
          oil products driving the need for more oil refineries.

     -    Higher oil prices have made heavier crude oil with higher sulfur
          content more attractive as a raw material, driving the need for more
          sophisticated vacuum processes to reduce the sulfur content.

     -    More demanding requirements for vehicle emissions that are effective
          in 2006 and 2007 are adding to the need for improvements to the sulfur
          reducing process in oil refineries.

     -    Continued global growth increases the need for electricity, therefore
          driving power


                                       3



generation development.

     -    The demand for plastics and related products is driving capacity
          expansions for ethylene plants in both Asia and the Middle East.

Our products are used by these industries for these processes. For the near
term, we are in an enviable position of being a market leader among end-users
such as ExxonMobil, Chevron and Shell, as well as with engineering procurement
contractors such as Bechtel Corporation, KBR and original equipment
manufacturers such as Elliott Ebara Turbomachinery Corporation. We cannot be
content, however, and must remain competitive while continuing to provide the
sophisticated engineering support, quality product and reliable service our
customers expect.

TRANSFORMATION FOR LONG-TERM MARKET ADVANTAGE

Lean manufacturing: We have the opportunity to strengthen our margins by
improving operational efficiencies, supply chain management and inventory
reduction. By implementing lean manufacturing, we believe we can shorten cycle
times, have customer demand pull product through our facility and have suppliers
provide inventory on demand. We expect these efforts will help us to realize
higher margins during strong business cycles and reduce the severity of the
impact of down cycles.

Automated design and quote processes: We believe having the ability to quickly
engineer, manufacture, and communicate highly-customized solutions is a value
proposition which is a key attribute for growing market share. Our customers are
demanding drawings at the time of order, or within weeks of order placement.
This requires a design system capable of capturing data during the quoting phase
and delivering a near complete solution at time of quote that is closely coupled
to our manufacturing processes. We plan to reduce the time to generate designs
and better capture, retain and re-employ the wealth of customized equipment
designs we create.


                                       4



Information management: With our new technologies, we expect to be able to
create a streamlined flow of order data from initial bid to the shop floor. As a
result, we should improve the sales of our products by offering faster response
to customer inquiries with engineering details, specific cost information and
itemized delivery information. We believe that applying computer programming
technology from initial bid through to the shop floor will enable us to better
capture the real costs of our business.

Reorganized business structure: In order to focus our business and drive
efficiencies, we have reorganized the company into five business groups -
Condensers, Ejectors, Pumps, Spare Parts, Heat Exchangers. The reorganization
included an evaluation of each of the business units, and as a result, our UK
pump manufacturing operation was discontinued. We have re-engineered our
business model for pumps and have been successful in lowering our total cost to
better serve our customers and position Graham for future growth in this key
business segment. By re-engineering our business model, we believe our capture
ratio for vacuum systems and pumps will increase due to our better overall cost
position.

Expanding marketing and sales presence: We have taken steps to increase our
presence in Asia and the Middle East by adding full-time sales coverage in both
regions in order to capitalize on the enormous potential we believe is available
in these regions. Our goal is to work with local sales representatives and
fabricators to optimize the ability of Graham to serve the local customer base
and export to more markets. We are also evaluating our approach to South
America, recognizing that growing economies will demand energy and power.

CONFIDENT OUTLOOK

The strength of Graham's brand, our skilled team, and the measures we are taking
to strengthen our future gives us confidence in our outlook. Generally, a solid
industrial cycle, such as the one we are currently in, could last three to five
years. We believe there is potential for this one to last longer because of the
driving force of the growing Asian economy. The cycle itself, however, could
have major fluctuations within it. Our objective is to maximize this cycle and
position the Company for such fluctuations or a downturn.

The employees of Graham consider the Graham brand a promise to our customers and
shareholders. That promise is excellence in everything we do and a commitment to
maintaining high standards in business ethics and business integrity. We are
focused on transforming Graham into a stronger, growing business.

Sincerely,


/s/ William C. Johnson

A CONVERSATION WITH MANAGEMENT

By transforming processes, we can improve our operational effectiveness and
reduce our cost structure while solidly positioning Graham to remain successful
in an ever-changing, competitive market.

Jim Lines, Vice President and General Manager

EXPANDING OUR GLOBAL PRESENCE

Our geographic sales growth strategy is designed to address expanding
opportunities in our export markets. We are the beneficiaries of the current
surge in planned capital spending by refining, petrochemical and power companies
in both our domestic and export markets. Historically, our success has been
built on the oil refining, petrochemical and power generation markets, which
represent approximately 60-70% of our sales. These industries are seeing
significant activity, particularly in Asia, the Middle East, Western Canada and
the Latin America region. Graham has a rich history of proven installations in
these regions. We believe we have a competitive advantage with these industries
because of our 'engineering answers' sales strategy.

Although China is not a new market for us, we are expanding our presence there.
We have established a sales office in China and are aggressively pursuing the
development of a strong sales representative network throughout the region. Our
objective is to establish effective and broad-reaching sales channels, develop
relationships with key decision-makers and local fabricators, and win a greater
share of the business. In Europe, we appointed a sales management team to
reconnect with engineering, procurement and construction contractors and process
licensors following a recent decision to discontinue our UK pump business.
European contractors, process licensors and turbomachinery equipment
manufacturers are active in the Asian, Middle East and Latin American planned
expansions. Maintaining our presence and developing a network of sales
representatives will help extend Graham's reach into these regions.

We are also evaluating other regions including South America, South Africa and
Canada. In South America, we have the potential to establish an office and
improve our sales representative network, similar to our approach in China and
Europe.

Our ultimate goal is to grow the business beyond our current customer base in
order to maximize sales during the up cycles and have a broader, global sales
presence to minimize the down cycles, which capital equipment businesses are
subject to endure.

Steve Northrup, Vice President and Chief Technology Officer

TRANSFORMING PROCESSES THROUGH INFORMATION SYSTEMS

The seed for the development of Graham's strong brand name in the markets it
serves is its top-notch engineering expertise, which through the years,
consistently developed and delivered complex system solutions to meet each
customer's unique requirements.


                                        6



Our job-specific approach to the design and development of engineered solutions
in an engineer-to-order environment has evolved in sophistication as our
engineering skills have advanced over more than 70 years. However, we have not
historically employed computer systems that fully capture, leverage and improve
our intellectual property and expertise. That is why we have embarked on an
ambitious program to automate the bid proposal and job design processes to fully
engage a lean manufacturing philosophy.

To automate the sales and design processes, we are scrutinizing every internal
process by completing detailed workflow analysis and process mappings. We are
looking at every aspect of the sales and engineering processes, from initial
customer contact and proposal preparation to job drawings and production design.
The detailed information captured for each job will feed into our manufacturing
processes. With this automation, we can optimize our inventory control program
and improve our production planning and scheduling system.

We expect the impact to the customer experience to be great. We can increase our
value for our customers by reducing cycle times, leveraging our expertise and
providing superior project management through increased consistency and accuracy
for each job.

This investment in our information management systems should measurably improve
our operational effectiveness and reduce our cost structure while solidly
positioning Graham to remain successful in an ever-changing, competitive market.

Ron Hansen, Vice President of Finance and Administration and Chief Financial
Officer

ACCOUNTABILITY AND ENHANCED UNDERSTANDING

As Graham is undergoing significant transformation in its processes through
automation, we are defining the characteristics we must have for us to grow and
succeed well beyond this current strong cycle. The upgrade of our systems and
increased use of automation in our processes from bid through delivery is
designed to give us an improved ability to define the metrics that will keep us
on track with our vision for growth. Going forward, we recognize that we cannot
be dependent only on the industrial cycle to achieve profitability.

Transformation includes accountability. Internally, we are defining specific
metrics to monitor and objectives to achieve that are associated with leaning
our manufacturing process and improving cash management. These include the level
of inventory turn, which has room for improvement, and shortened cycle time from
purchase order to delivery. The automation efforts should help to strengthen our
material procurement functions by better defining material needs at the time of
submitting a proposal.

We fully recognize the need to be accountable to our shareholders. The markets
in which we operate tend to be highly cyclical, leaving us vulnerable on the top
line. Increasing our emphasis on spares and broadening our sales network is
intended to help to mitigate this problem. Where we can provide greater
understanding for our investors is in our earnings power and its sustainability.
Our goal in 2006, as we implement our new systems and transform our business, is
to expand our disclosure in order to improve transparency for the investment
community.
