Enzo Biochem Reports Improved Third Quarter Results

Enzo Clinical Labs Achieves Sharply Increased Operating Results and Margins on 28% Increase in Revenues; Enzo Life Sciences Operating Income Up 31%

NEW YORK--(BUSINESS WIRE)-- Enzo Biochem, Inc. (NYSE:ENZ) today reported operating results for the three months ended April 30, 2011, including:

    --  EBITDA (earnings before interest, taxes, depreciation and amortization,
        a non-GAAP measure) improvement of 73%, or $2.4 million;
    --  A 9% increase in total revenues, reflecting a 28% increase in Enzo
        Clinical Lab revenues for the period;
    --  Improved margins at both Enzo Labs and Enzo Life Sciences, resulting in
        a 17% increase in gross profits;
    --  A 54% reduction, or $2.5 million improvement, in the quarter's net loss
        as compared to a year ago;

"As our third quarter results reflect, our efforts to date to better integrate our Clinical Lab and Life Sciences activities, increase market share, reduce costs and enhance productivity are starting to yield very tangible results," said Barry Weiner, President. "These achievements are being realized as we continue to position Enzo for the new and increasing shifts in medical diagnostics to personalized medicine and gene-based, or molecular testing, in addition to the development of our own laboratory developed tests and realize the planned benefits from our cost management plan."

Third Quarter Operating Results

Total revenues increased to $25.8 million, up from $23.7 million in the preceding January 2011 quarter and from $23.8 million in the corresponding year-ago period. Product revenues were up almost 7% sequentially, though down a slight 1% year over year, while Clinical Lab revenues at $13.8 million, increased 12.5% and 28%, respectively. Royalty and licensing fee income, based on current payments received, declined to $1.1 million, from $1.2 million and $1.9 million sequentially and year-over-year, respectively. Reduced product sales is indicative of the Company's program to increase direct sales and rationalize certain distribution business, while the Clinical Labs business benefited from organic growth as well as the previously announced major new payer contract, which also has enabled Enzo to tap into a wider network of physicians not previously serviced.

As a result, gross profit improved to $12.4 million, from $10.5 million a year ago, a 17% improvement (and $10.3 million sequentially), with the gross margin at 48%, compared to 44% year over year. Selling, general and administrative expenses, as a percentage of total revenues, improved to 42%, from 50% a year ago, although, in other expenses, the Company incurred higher legal costs and an increased provision for uncollectible accounts receivables, the latter due principally to the increased revenues at Enzo Clinical Labs activity. The net loss for the period declined to ($2.1) million, or ($0.05) per diluted share, down from a net loss a year ago of ($4.6) million or ($0.12) per diluted share and a net loss in the preceding January 2011 quarter of ($5.7) million, or ($0.15) per diluted share. EBITDA loss for the period improved to ($0.9) million as compared to ($3.3) million in the year ago period, a 73% improvement. Enzo's finances, as of April 30, 2011, remained strong and highly liquid, with cash and cash equivalents and short term investments over $27.5 million, and working capital of $37.2 million.

Year to Date Operating Results

For the nine months ended April 30, 2011, total revenues increased 4%, to $75.2 million, from $72.1 million a year ago, including an 18% increase in Clinical Lab revenues. Gross margin increased 4%, to $36.2 million, from $34.7 million, a year ago, with gross profit margin equal to 48% for both periods. Operating expenses, excluding the prior year legal settlement, as a percentage of total revenues, improved to 60%, from 65% a year ago, with SG&A alone improving 7%, to 44%, from 51% a year ago. The net loss was reduced by $7.8 million to ($8.9) million or ($.23) per diluted share. Adjusting for the legal settlement in 2010, the net loss improved by $4.1 million or $.11 per diluted share. EBITDA, after the adjustment for the settlement, improved by $4.2 million.

Segment Quarter Results

Enzo Clinical Labs, as noted, logged strong third quarter revenue gains, the result of organic growth, reflective of increased clients and test offerings and the new payer contract, which has increased access to physicians not previously served. Working jointly with Enzo Life Sciences, Enzo Clinical Labs, is increasingly focused on the development of in-house diagnostic tests, plus the addition of esoteric tests and the marketing of its personal diagnostic services. Revenues increased 28%, to $13.8 million, a record quarter. The gross margin increased to $5.5 million, or 40% of revenues, compared to $2.9 million, or 27%, a year ago, due not only to the leverage from increased volume but also from reduced overhead and process improvements that favorably impacted costs. SG&A was up slightly, in part due to increased sales commissions from a broader sales force that is now operative, although as a percentage of revenues, it declined to 33% from 41% a year ago. The Clinical Labs' operating loss was just $70,000, as compared to a year-ago loss of ($2.2) million.

Enzo Life Sciences posted operating income of $0.9 million, up from $0.7 million in the year ago period, despite a 1% decline in product sales to $10.9 million. Royalty and licensing fee income, based on current payments received, declined to $1.1 million, from $1.9 million year-over-year. Despite the reduction in revenues, the improvement in operating income reflects a more profitable product line-up and the benefits from the on-going cost improvement and business integration program, impacting staffing levels and realignment of facilities and R&D, all designed to achieve greater efficiencies and profitability.

NON-GAAP Financial Measures

To comply with Regulation G promulgated pursuant to the Sarbanes-Oxley Act, Enzo Biochem attached to this news release and will post to the Company's investor relations web site (www.enzo.com) any reconciliation of differences between non-GAAP financial information that may be required in connection with issuing the Company's quarterly financial results.

The Company uses EBITDA, as a measure of performance to demonstrate earnings exclusive of interest, taxes, depreciation and amortization. The Company manages its business based on its operating cash flows. The Company, in its daily management of its business affairs and analysis of its monthly, quarterly and annual performance, makes its decisions based on cash flows, not on the amortization of assets obtained through historical activities. The Company, in managing its current and future affairs, cannot affect the amortization of the intangible assets to any material degree, and therefore uses EBITDA as its primary management guide. Since an outside investor may base its evaluation of the Company's performance based on the Company's net loss not its cash flows, there is a limitation to the EBITDA measurement. EBITDA is not, and should not be considered, an alternative to net loss, loss from operations, or any other measure for determining operating performance of liquidity, as determined under accounting principles generally accepted in the United States (GAAP). The most directly comparable GAAP reference in the Company's case is the removal of interest, taxes, depreciation and amortization.
