                            POWELL INDUSTRIES REPORTS
                        FISCAL 2003 THIRD QUARTER RESULTS


HOUSTON -- AUGUST 27, 2003 -- Powell Industries, Inc. (NASDAQ: POWL), a leading
manufacturer of equipment and systems for the management and control of
electrical energy and other critical processes, today announced results for the
fiscal 2003 third quarter ended July 31, 2003.

         Revenues for the third quarter of 2003 were $60.4 million compared to
revenues of $74.3 million for the third quarter of 2002. Net income from
continuing operations for the third quarter was $1.3 million, or $0.13 per
diluted share, compared to $4.5 million, or $0.42 per diluted share, for the
third quarter of fiscal 2002. Powell generated $14.3 million in free cash flow
(defined as total cash flow from operations of $14.9 million less all capital
expenditures of $588 thousand) in the third quarter. Year to date Powell has
generated $30.3 million in free cash flow.

         "Business conditions remained difficult and competitive pressures
intense during our third quarter resulting in EPS at the bottom of our
projections," stated Thomas W. Powell, chairman and chief executive officer.
"However, it does appear that domestic opportunities and inquiry levels have
stabilized and international opportunities are improving. With more attention
now focused on the aging electric utility infrastructure, we see longer term
opportunities for the Company in the areas of increased power transmission,
generation, power quality and general systems upgrades."

         Revenues through nine months of fiscal 2003 were $196.2 million
compared to revenues of $231.1 million for the same period of fiscal 2002. Net
income including the effect of a change in accounting principle of $510 thousand
for the adoption of Statement of Financial Accounting Standards (SFAS) No. 142,
"Goodwill and Other Intangible Assets," through nine months was $5.9 million, or
$0.55 per diluted share, versus $12.8 million, or $1.19 per diluted share.
Excluding the effect of a change in accounting principle, net income was $6.4
million, or $0.60 per diluted share, compared to $12.8 million, or $1.19 per
diluted share.


         The Electrical Power Products segment recorded revenues of $53.1
million in the third quarter compared to $67.8 million in the third quarter a
year ago. Third quarter income from continuing operations before income taxes
for Electrical Power Products totaled $1.8 million versus $6.7 million in last
year's third quarter.

         Process Control Systems revenues for the third quarter were $7.3
million compared to $6.5 million in last year's third quarter. Income from
continuing operations before income taxes for Process Control Systems totaled
$0.4 million versus $0.4 million a year ago.

         The company's order backlog as of July 31, 2003, was $178.4 million,
compared to $203.0 million at the end of the second fiscal quarter of 2003 and
$215.3 million at the end of the third fiscal quarter one year ago. New orders
placed during the third quarter totaled $35.8 million versus $67.9 million in
the third quarter a year ago and compared to $98.7 million in the second fiscal
quarter, which included $37 million for the previously announced award for the
Lincoln and Holland tunnels.

OUTLOOK

         The following statements are based on the current expectations of the
company. These statements are forward looking and actual results may differ
materially as further elaborated in the last paragraph below.

         Powell Industries expects fiscal fourth quarter earnings to range
between $0.10 and $0.15 per diluted share and full year 2003 earnings from
continuing operations to range between $0.65 and $0.70 per diluted share, which
is the midpoint of our earlier guidance range of $0.60 to $0.75. Full year 2003
revenue is now expected to range between $250 million and $255 million, and free
cash flow, defined as total cash flow from operations less all capital
expenditures, is expected to range between $30 million and $33 million.
