Intel blamed the ongoing price war in the chip market on Tuesday for failing to hit analysts' expectations for its fiscal second quarter.
But Integraph, which is fighting a high profile lawsuit with the chip giant, blamed Intel for the "weak" hardware sales that it has suffered during its second quarter.
As a result, the supplier said it expected second quarter revenues to be $25 million lower than internal targets, which would hit its earnings.
The First Call analysts' consensus expects Intergraph to post losses of $0.27 per share and its shares closed down $0.9375 at $5.375.
But Intel's shares were also not immune to the bad news. They closed down $0.0625 at $65.375, despite revenues that rose 14 per cent to $6.7 billion, on profits up 49 per cent to $1.7 billion or $0.51 per share. The First Call analysts' consensus had expected earnings of $0.53, however.
But ironically, it was Intel itself that sparked the price war, which it claims hurt its bottom line. Earlier this year, the supplier lowered the prices, particularly of its Celeron chip, to regain market share from main rival, AMD.
Although Intel's percentage of retail PC sales is now to 49 per cent from a low of 34 per cent in February as a result, the company has suffered from selling its processors at about $195 each, down from $218 last quarter.
In a bid to ward off an overly negative reaction when the stock markets open on Wednesday, however, the firm went on the offensive, saying it expected good times ahead.
Craig Barrett, Intel's chief executive, said: "As expected, second quarter revenue reflected a seasonal slowdown and we look forward to a strong second half."
But promises might not be enough for investors. Dan Niles, technology analyst at BancBoston Robertson Stephens, said: "Ultimately, we buy these stocks for earnings. When everyone cuts their numbers tomorrow morning, it may be difficult for the stock to stay up."
Intergraph, on the other hand, filed suit against Intel in November 1997, alleging patent infringement, anticompetitive behavior and antitrust violations. Although it won a key ruling last month when a judge ruled that Intel did not hold rights to disputed technology at the core of the litigation, the lawsuit would appear to have harmed it.
The company's financials were hurt last year and in the first quarter of this year by expenses incurred as a result of the litigation, but until today's statement, it had been forecasting a return to profitability.
Jim Meadlock, Integraph's chief executive, said: Our current computer hardware offering is not sufficiently differentiated to overcome the impact of Intel's actions against Intergraph. We have resized the computer hardware development and sales organisations in line with the level of hardware orders and revenues being generated."
He added that this resizing would result in a $3 million charge against its second quarter earnings, which are due to be released on 26 July. It will also report a gain of about $11 million from the April sale of its Intercap Graphics Systems subsidiary.
