CHATSWORTH, California, November 4, 2004 . . . CHAD Therapeutics, Inc. (ASE:CTU) announced today that net earnings for the second quarter of fiscal 2005 tripled versus the same period last year on a 19% increase in net sales. For the first six months of fiscal 2005, net earnings increased 92% compared to the same period of fiscal 2004.

For the three months ended September 30, 2004, revenue increased 19% to $6,309,000, an eight-year high, from $5,284,000 for last year’s second quarter. Net earnings increased 203% to $455,000, or $0.04 per diluted share, from $150,000, or $0.02 per diluted share, a year earlier.

For the first six months of fiscal 2005, revenue increased 13% to $12,408,000 from $10,953,000 for the first six months of fiscal 2004. Net earnings increased 92% to $717,000, or $0.07 per diluted share, from $374,000, or $0.04 per diluted share, for the first half of fiscal 2004.

At September 30, 2004, CHAD had no long-term debt and cash of $3,007,000, or 21% of total assets. At March 31, 2004, cash was $2,708,000.

Earl L. Yager, Chief Executive Officer and President, said that domestic sales for the second quarter grew 15% as CHAD began shipping significant numbers of its new SAGE Therapeutic Device in September. “Introduced earlier this year, our new SAGE device employs our proprietary technologies to sense an oxygen patient’s movements and automatically adjust the rate of oxygen delivery to reduce the risk of oxygen desaturation as activity increases. The SAGE device, along with CHAD’s OXYMATIC® 400 Series electronic conservers and CYPRESS OXYPneumatic® conservers, provide the industry’s widest range of cost-effective choices for homecare providers to satisfy individual patient requirements and preferences for ambulatory oxygen products.”

Yager continued, “We also introduced our new LOTUS electronic oxygen conserver at the 25^th annual Medtrade show for the home health care industry held in Orlando in October. Earlier, we announced the receipt of FDA clearance to market this sleek and lightweight addition to our electronic conserver line. It contains several enhancements to our popular OXYMATIC 400 series conservers and will be offered with or without a breath sensing alarm. The LOTUS conservers are powered by two AA-size batteries that will provide up to four months of normal usage and an optional rechargeable battery pack will also be available for these devices.”

Yager added, “The introduction of the LOTUS conserver represents another step in the enhancement of our oxygen conserving and therapeutic device product lines, which is an important element of our strategic growth plan. Our success in this area is creating the resources to pursue the other elements of our growth plan — to expand usage of the TOTAL O₂® Delivery System and continue work on the products we are developing for the sleep disorder and related markets.

CHAD Therapeutics Reports Higher Revenue and Net Earnings For The Second Quarter
and First Half of Fiscal 2005
November 4, 2004

“We continue to make progress with the initial products we are developing for the sleep disorder market, and are currently evaluating alternative distribution models for these new products. We have developed engineering prototypes for several devices and are pleased with the results of preliminary testing we have done on these devices. Our next steps will be to make a decision on distribution and clinical testing that will likely begin after the first of the year. We will provide more information on our progress as it becomes available.”

Yager concluded, “Based on these factors, and assuming that current sales and expense trends continue, we continue to believe CHAD will generate net earnings of between $2,500,000 and $2,700,000, or $0.24 to $0.26 per diluted share, for the fiscal year ending March 31, 2005.” For fiscal 2004, CHAD reported net earnings of $1,001,000, or $0.10 per diluted share.

At September 30, 2004, the company had fully utilized its net operating loss carrybacks and Federal net operating loss carryforwards and had approximately $2,013,000 in California net operating loss carryforwards available to offset future taxable income. The Company also has approximately $793,000 in net deferred tax assets, upon which a valuation allowance has been placed, that will be available to offset future income tax expense. In September of 2002, the State of California enacted legislation that suspended the utilization of net operating loss carryforwards during tax years starting in 2002 and 2003 effective retroactively to January 1, 2002. As a result, CHAD has been unable to use its California net operating loss carry forwards until the tax year that began April 1, 2004.
