&#8211; </font>IPG Photonics Corporation (Nasdaq: IPGP) today revised its guidance for
the second quarter ended June 30, 2009. The Company anticipates revenues in the
range of $40 to $41 million and a net loss per share in the range of $0.03 to
$0.04 for the second quarter of 2009.&#160;&#160;The Company had previously
expected revenue in the range of $39 to $45 million and earnings per share in
the range of $0.01 to $0.07.</font></div>

we expect to report second-quarter revenue within our original guidance range,
we anticipate that earnings per share will be below the range provided on May 5,
2009,&#8221; said Dr. Valentin Gapontsev, IPG&#8217;s Chief Executive
Officer.&#160;&#160;&#8220;Expected earnings are lower than anticipated due to lower
absorption of fixed costs due to a reduction in the level of inventory during
the period, as well as greater than anticipated pricing pressures related to the
current macro-economic and competitive environments.&#160;&#160;We expect that
pricing pressure will continue as long as the global economic downturn is having
a negative effect on sales volumes in the industry.&#160;&#160;In addition, we
increased R&amp;D expenses in the quarter to aggressively accelerate the
development of a series of new products.&#160;&#160;Despite the small loss, IPG
generated positive cash flow substantially due to a reduction in inventory
levels and lower capital expenditure levels.&#8221;</font></div>

visibility remains limited, we believe that the Materials Processing market will
likely remain soft throughout the remainder of the year,&#8221; added
Gapontsev.&#160;&#160;&#8220;At the same time, we are encouraged that sales of high
power lasers increased compared with prior year levels in the otherwise weak
Materials Processing market.&#160;&#160;In addition, it is promising that sales
for Medical, Communications and Advanced Applications grew over the second
quarter of last year.&#8221;</font></div>
