THE NINE MONTHS ENDED SEPTEMBER 30, 2003

HOUSTON--(PRNEWSWIRE/FIRST CALL via COMTEX)--November 20, 2003--Allis-Chalmers
Corporation (OTC: ACLM.OB) today announced earnings for the third quarter of
2003.

Results for the Third Quarter Ended September 30, 2003.
- -------------------------------------------------------

         The Company announced that revenues for the three months ended
September 30, 2003 increased to $8,089,000 compared to $4,775,000 in the
comparable period of 2002. Revenues for the three months ended September 30,
2003 for the Casing, Directional Drilling, and Compressed Air Drilling Services
segments were $2,559,000, $3,353,000 and $2,177,000, respectively. Revenues for
the three months ended September 30, 2002 for the Casing, Directional Drilling
and Compressed Air Drilling Services were $2,197,000, $1,785,000 and $793,000,
respectively. Revenues for the third quarter of 2003 increased over the third
quarter of 2002 due to the increased activity in the drilling market in Mexico
and increased market share in the domestic market Casing, Directional Drilling
and Compressed Air Drilling Services. The consolidation of the operating results
of the joint venture between Mountain Air and M-I Air Drilling into the
financial statements of AirComp LLC and the Company also increased revenues in
the quarter.

         The Company had operating income for the period of $727,000 compared to
an operating loss of ($680,000) in the third quarter of 2002. Operating income
(loss) for the three months ended September 30, 2003 for the Casing, Directional
Drilling, Compressed Air Drilling Services and General Corporate segments were
$913,000, $120,000, $171,000 and ($477,000), respectively. Operating income
(loss) for the three months ended September 30, 2002 for the Casing, Directional
Drilling, Compressed Air Drilling Services and General Corporate segments were
$749,000, ($44,000), ($269,000) and ($1,116,000), respectively.

         The Company had net income of $1,224,000, or $0.06 per common share,
for the third quarter of 2003 compared with a loss of ($1,205,000), or ($0.08)
per common share, for the third quarter of 2002. The Company recorded a one-time
gain of $1,034,000 on the reduction of the note payable in the third quarter of
2003 as a result of settling a lawsuit against the former owners of Mountain Air
Drilling Service Company. The gain was calculated by discounting the note
payable to $1,469,152 using a present value calculation and accreting the note
payable to $1,863,195, the amount due in September 2007. The Company will record
interest expense totaling $394,043 over the life of the note payable beginning
July 2003.



Results for the Nine Months Ended September 30, 2003.
- -----------------------------------------------------

         The Company had revenues for the nine months ended September 30, 2003
of $22,428,000 compared to $12,265,000 in the comparable period of 2002.
Revenues for the nine months ended September 30, 2003 for the Casing,
Directional Drilling, and Compressed Air Drilling Services segments were
$7,712,000, $10,336,000 and $4,380,000, respectively. Revenues for the nine
months ended September 30, 2002 for the Casing, Directional Drilling and
Compressed Air Drilling Services were $5,445,000, $4,058,000 and $2,762,000,
respectively. Revenues for the nine months ended September 30, 2003 increased
over the same period of 2002 due to the increased activity in the drilling
market in Mexico and increased market share in the domestic operations of
Casing, Directional Drilling and Compressed Air Drilling Services. The joint
venture between Mountain Air and M-I Air Drilling and the consolidation of the
results of operations of AirComp into the financial statements of the Company
and the fact that our 2002 operations included only eight months of the
operations of Strata Directional Technologies, Inc. and Jens' Oilfield Service,
Inc., which were acquired effective February 6, 2002 reflected the increased
revenues in 2003 over the same period in the prior year.

         The Company had operating income for the nine months ended September
30, 2003 of $2,457,000 compared to an operating loss of ($1,205,000) for the
nine months ended September 30, 2002. Operating income (loss) for the nine
months ended September 30, 2003 for the Casing, Directional Drilling, Compressed
Air Drilling Services and General Corporate segments were $3,070,000, $613,000,
($52,000) and ($1,278,000), respectively. Operating income (loss) for the nine
months ended September 30, 2002 for the Casing, Directional Drilling, Compressed
Air Drilling Services and General Corporate segments were $1,707,000,
($187,000), ($716,000) and ($2,009,000), respectively.

         The Company had net income of $624,000, or $0.03 per common share, for
the nine months ended September 30, 2003 compared with a loss of ($3,247,000),
or ($0.18) per common share, for the nine months ended September 30, 2002. The
Company recorded a one-time gain of $1,034,000 on the reduction of the note
payable in the third quarter of 2003 as a result of settling a lawsuit against
the former owners of Mountain Air Drilling Service Company. The gain was
calculated by discounting the note payable to $1,469,152 using a present value
calculation and accreting the note payable to $1,863,195, the amount due in
September 2007. The Company will record interest expense totaling $394,043 over
the life of the note payable beginning July 2003.

         Munawar H. Hidayatallah, the Company's Chairman and Chief Executive
Officer stated, "We are extremely proud of the dramatic turnaround at
Allis-Chalmers Corporation. The Company executed its strategic objectives
successfully including the formation of AirComp LLC, a joint venture between
Mountain Compressed Air and the Air Compressor Division of MI Fluids, which in
turn is a joint venture between Smith International and Schlumberger. The
successful implementation of the Company's business plan was due to the
dedication and commitment of the management team. Jens Mortensen has been
appointed Chief Executive Officer of Jens' Oilfield Services, Inc. and retains
the position of President and Chief Operating Officer of Allis-Chalmers
Corporation; Dave Wilde has been appointed as President, Chief Executive Officer
