TECH/OPS SEVCON REPORTS THIRD QUARTER RESULTS

Southborough, Mass. August 4, 2004..... Tech/Ops Sevcon, Inc. (AMEX symbol TO)
reported that net income for its third fiscal quarter was $103,000, or $.03
per diluted share, which was in line with last year's results for the same
period when the Company had net income of $98,000, or $.03 per diluted share.
Revenues for the third quarter were $7,486,000, an increase of $1,525,000, or
26%, compared to the prior year's $5,961,000. Foreign currency fluctuations
accounted for $435,000 or 7% of the increase in reported sales but had an
insignificant impact on operating income. Volumes increased by 18% compared to
the third quarter of last year mainly due to gains in the controls business.
Engineering expense, mainly on advanced new products, was $296,000 higher than
the third quarter of last year. Operating income for the third quarter was
$121,000 compared to $161,000 in the same quarter last year.

For the nine month period net income was $326,000, or $.10 per diluted share,
compared to $315,000, also $.10 per diluted share, last year. Revenues in the
first nine months of this year were $21,255,000, an increase of $3,481,000,
or 20%, compared to last year. Foreign currency fluctuations accounted for
$1,635,000 or 9% of the increase in reported sales. Volumes were 11% higher
than the prior year period. The gross profit percentage increased to 40.3%
of sales compared to 38.8% in the same period last year. Higher operating
expenses, mainly related to new product engineering, sales and marketing and
adverse foreign currency affects increased operating expenses by $1,569,000
compared to the same period last year. Operating income for the nine months
was $574,000 compared to $478,000 in the first nine months of fiscal 2003.
The increase in operating income was mainly due to increased volumes and
foreign currency fluctuations, partially offset by the higher operating
expense mainly related to new products.
