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.

Excerpt of Second Quarter 2003 Earnings Conference Call
May 8, 2003

Operator:            Good morning ladies and gentlemen and welcome to the EMCORE
second quarter 2003 earnings teleconference.  At this time all participants have
been  placed  on a  listen-only  mode and the floor  will be open for  questions
following the presentation.  If at any point during the presentation you wish to
register a question  you may do so by pressing  the numbers one followed by four
on your  touch-tone  phone.  It is now my  pleasure to  introduce  your host Mr.
Victor Allgeier. Please go ahead sir.

Victor Allgeier:     Thank you and good morning everyone.  Yesterday  after  the
close of markets,  EMCORE  released its fiscal 2003 second quarter and six-month
results.  By now your should have received a copy of the press  release.  If you
have not received a release, please call our office at (212) 227-0997.

                     With  us  today  from   EMCORE,  Reuben F.  Richards,  Jr.,
President and Chief Executive Officer, and Tom Werthan, Vice President and Chief
Financial Officer. Tom will review the financial results and Reuben will discuss
business highlights before we open the call up to your questions.

                     Before we begin we would like to  remind  you  that some of
the comments made during the  conference  call and some of the responses to your
questions by management may contain forward-looking  statements that are subject
to risks and  uncertainties as described in EMCORE's  earnings press release and
filings with the SEC. I will now turn the call over to Tom.

Tom Werthan:         Thanks,  Vic, and good  morning to everybody and thanks for
joining us today as we review our second quarter.  Revenues for the quarter came
in at just under $28 million  and this is up 19% from our first  quarter and 20%
year over year. And let me review the revenue performance by product.

                     First on systems, revenues came  in just under $11 million.
That's down 22% sequentially but up 148%  year-over-year.  Despite the fact that
we were down  sequentially we will experience a pretty healthy increase in Q3 as
our backlog is increased pretty dramatically.  I'll review that in a little more
detail later on in the presentation when I discuss backlog.

                     On RF materials and sensors, revenues were $2 million. That
is down 2%  sequentially  and 63%  year-over-year.  On fiber  optics,  which now
includes  Ortel,  but to keep it apples  to  apples  our  previous  fiber  optic
products came in at $2.6 million.  That is up 12%  sequentially  and Ortel as we

indicated in the press release contributed about $7.1 million in revenues which was in line with our expectations. Finally on PhotoVoltaics, revenues were $5.2 million. That's up 3% sequentially and down 52% year-over-year primarily because last year at this time we had a large Boeing contract that fell in the quarter. So revenues on the whole were just under $28 million, again a 19% increase sequentially and 20% year-over-year. (inaudible) gross margins for the quarter then were 10%, that was up a couple of basis points from last quarter. Again the fact that we're operating at a 20% capacity remains the biggest impact on gross margins. Since the systems margins are in the mid thirties while materials overall are slightly negative, but on a non GAAP basis, meaning a cash basis if you eliminate the depreciation charges found in our cost of good sold gross margins for systems and materials would be 37% and 15% respectively. We did have some poor yields in our PhotoVoltaics product line in this quarter that also impacted some gross margins. SG&A expenses increased from $5.8 million in Q1 to $7.4 million the current quarter the increase of the $1.6 million is entirely related to the acquisition of Ortel in January. Year-over-year SG&A decreased $2.1 million or 22% and again giving apples to apples comparison with non GAAP disclosure elimination Ortel from SG&A the decrease year-over-year was $3.7 million or about 39%. R&D expenses increased from $3.6 million in the first quarter to $5.4 million in the current quarter, or and increase of $1.8 million. Again, Ortel's R&D amounted to about 1.1 million or 60% of this increase. The remaining increase of about $700,000 links to acquisition of Alvesta earlier in the year and the fiber optic projects they're working on as well as some PhotoVoltaic projects. Year-over-year R&D decreased $6.2 million or 53% and, again for non-GAAP disclosure just making it apples to apples by not including Ortel, R&D did decrease by $7.3 million or about 63%. Below the line net interest expense was flat sequentially and year-over-year at about $1.7 million. The loss in GELcore, our joint venture with GE Lighting was $731,000. That's an increase sequentially of about 160 thousand but a decrease of $120,000 year-over-year. The increase in the loss is attributable to lower revenues in GELcore's first quarter, however their backlog has increased and those revenues should increase nicely in the coming quarters. The net loss is 12.5 million, or ($.0.34) per share. Ortel contribution in the quarter as previously mentioned was 7.1 million in revenues and that contributed to our loss of about four cents. Again from a non-GAAP disclosure not including Ortel to give apples to apples our loss per share would have been about ($.30) cents. . . .
