EMCORE Corporation Reports Fiscal 2003 Second Quarter and Six Month Results

     o    Second Quarter Revenues Increase 19% Sequentially from First Quarter
          to $27.7 million

     o    Revenues Expected to Increase 20% in the Third Quarter to $32-$34
          million

SOMERSET,  N.J.,  May  7,  2003  /PRNewswire-FirstCall/  --  EMCORE  Corporation
(Nasdaq:  EMKR - news), a leading  provider of  semiconductor  technologies  for
global  communications  applications,  today reported  financial results for the
fiscal 2003 second quarter ended March 31, 2003.

Revenues for the quarter ended March 31, 2003 were $27.7 million, an increase of
20% from the $23.1 million  reported in the second quarter of fiscal 2002 and an
increase of 19% from the $23.2  million  reported in the first quarter of fiscal
2003.  Revenues for the six months ended March 31, 2003 were $50.9  million,  an
increase of 21% from the $42.2  million  reported in the six months  ended March
31, 2002. For the six-month  period,  systems-related  revenues of $24.6 million
have increased 68% from the prior year and  materials-related  revenues of $26.3
million  have  decreased  5%  from  the  prior  year.  On  a  sequential  basis,
systems-related revenues decreased 22% and materials-related  revenues increased
80% from the prior quarter. In late January,  EMCORE acquired Agere's West Coast
optoelectronics business, ORTEL Corporation,  for approximately $26.2 million in
cash. Ortel contributed approximately $7.1 million of materials-related revenues
to the second quarter of fiscal 2003.

On a generally  accepted  accounting  principles  (GAAP) basis, net loss for the
second quarter of fiscal 2003 was $12.5 million or $0.34 loss per share compared
to net loss of $68.7  million or $1.88  loss per share in the second  quarter of
fiscal  2002 and net loss of $2.9  million  or $0.08 loss per share in the first
quarter of fiscal 2003. The increase in operating expenses in the second quarter
of fiscal 2003 when  compared  to the first  quarter of fiscal 2003 was a direct
result of the ORTEL acquisition.  Excluding impairment and restructuring charges
of $50.4  million,  net loss for the  second  quarter  of fiscal  2002 was $18.3
million or $0.50 loss per share.  Excluding the gain from debt extinguishment of
$6.6 million,  net loss for the first quarter of fiscal 2003 was $9.5 million or
$0.26 loss per share.

Net loss for the six months ended March 31, 2003 was $15.4 million or $0.42 loss
per share  compared to net loss of $99.7 million or $2.74 loss per share for the
six months ended March 31, 2002. Excluding impairment,  restructuring, and other
expense from fiscal 2002 and the gain from debt extinguishment from fiscal 2003,
net loss for the six months ended March 31, 2003 was $22.1 million or $0.60 loss
per share,  compared to net loss of $36.0 million or $0.99 loss per share in the
six months ended March 31, 2002.

"We  continue  to meet the  challenges  in our target  markets,  and we are very
excited about the recent  acquisition of ORTEL and the  opportunities it creates
for our  Company,"  said Reuben F.  Richards,  Jr.,  President and CEO of EMCORE
Corporation.  "ORTEL  complements  our current  portfolio of solutions  for high
speed data and  telecommunications  networking systems,  and allows us to extend
our  leadership  into  a new  market  area  for  CATV  and  Fiber  to  the  User
applications  (FTTX).  We are also pleased that EMCORE's  cost cutting  measures
have resulted in  considerable  improvement  to our bottom line and cash flows."
commented  Richards.  "The significant  decline in operating expenses from prior
year and expected sequential revenue growth demonstrates  EMCORE's commitment to
streamlining its operations and improving shareholder value."

As a supplement to the consolidated financial statements presented on a GAAP basis, EMCORE provides additional non-GAAP measures for net loss and net loss per share in this press release. A non-GAAP financial measure is a numerical measure of a company's performance that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. EMCORE believes that the additional non-GAAP measures are useful to investors for financial analysis. Management uses these measures internally to evaluate its operating performance and the measures are used for planning and forecasting of future periods. However, non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Please consult the table immediately following the Statement of Operations for a reconciliation of GAAP results to non-GAAP results. EMCORE will discuss the results further on a conference call to be held tomorrow, Thursday, May 8, 2003 at 9:00 a.m. ET. To participate, U.S. callers should dial (888) 896-0863 and international callers should dial (973) 582-2703.
