Management Commentary

“The third quarter of fiscal 2014 earnings performance was below that achieved last year primarily as a result of quarterly timing. That said, for the first nine months of fiscal 2014, I am very pleased with ACETO’s performance, having achieved net income of $23.4 million, or diluted earnings per share of $0.82, compared to $16.9 million, or diluted earnings per share of $0.62, for the first three quarters of last year, representing increases of 38.5% for net income and 32.3% for EPS,” said Sal Guccione, Chief Executive Officer of ACETO.

Mr. Guccione continued, “In the third quarter of fiscal 2013, Aceto saw strong sales and profits of a higher-margin pharmaceutical ingredient, which recurred in early fiscal 2014 and, as expected and previously noted, did not repeat in the third quarter of fiscal 2014. In addition, sales and profits in our Human Health segment were impacted this fiscal quarter by increased competition on first-to-market products that were successfully launched last year coupled with a lower number of new drug launches in the current year. This resulted in a 6.5% decrease in sales and an 8.8% decrease in segment gross profit for the quarter. As previously indicated, we increased our research and development spending during the third quarter of this fiscal year in support of our pipeline of generic finished dosage product candidates. R&D expenses were $1.5 million for the quarter versus $0.9 million last year.”

Mr. Guccione also noted, “Regarding the Performance Chemicals segment, we saw improved profits on lower sales. This is due to an improved product mix, including higher gross margin contributions from the recent acquisition of Inter’actifs and decreased sales of lower margin products.”

Mr. Guccione concluded, “We remain focused on our long-term strategy of investing in and expanding our finished dosage generic pharmaceutical business. The increased R&D spend, coupled with our acquisition of PACK Pharmaceuticals, are important steps in executing this strategy. We are very pleased with the continued growth achieved by our Human Health segment, with sales and gross profits each increasing in excess of 20% through the first nine months of this fiscal year. At the same time, we remain focused on achieving incremental growth from both the Pharmaceutical Ingredients and Performance Chemicals segments."

Third Quarter Financial Review

Net sales for the third quarter of fiscal 2014 were $124.8 million, a decrease of 17.3% from $150.9 million reported in the third quarter of fiscal 2013. Total company gross profit was $25.0 million, a decrease of 20.8%, compared to $31.5 million in the third quarter of fiscal 2013. Selling, general and administration expenses were $16.4 million compared to $18.8 million in the same period last year, a 13.0% decrease. Included in fiscal 2014 in selling, general and administrative expenses was $1.0 million of expenses associated with the acquisition of PACK Pharmaceuticals. Fiscal 2013 SG&A included an earn-out expense of $2.8 million associated with the acquisition of Rising Pharmaceuticals. Research and development expenses this quarter totaled $1.5 million compared to $0.9 million in the prior year period. Operating income totaled $7.1 million compared to $11.7 million in the third quarter last year, a 39.7% decrease. Net income was $5.4 million, or $0.19 per diluted share, compared to net income of $7.6 million, or $0.28 per diluted share, for the comparable quarter of fiscal 2013.

Human Health segment sales were $33.9 million, a decrease of 6.5%, compared to $36.3 million for the third quarter of fiscal 2013. The sales decrease primarily resulted from increased competition for several products at Rising Pharmaceuticals. These products were successful first-to-market launches in fiscal 2013 and are now seeing greater competition, as anticipated. Gross profit for the segment was $10.1 million, a decrease of 8.8%, compared to $11.1 million for the third quarter of fiscal 2013.

Pharmaceutical Ingredients segment sales were $47.8 million, a decrease of 22.6%, compared to $61.8 million for the third quarter of fiscal 2013 due primarily to a decline in sales, both domestically and abroad, of pharmaceutical intermediates. In addition, the third quarter of fiscal 2013 included initial sales of a new high margin API, which as expected had no sales in the current period. Gross profit was $7.4 million, a decrease of 44.6%, compared to $13.4 million for the third quarter of fiscal 2013.

The Performance Chemicals segment sales were $43.0 million, a decrease of 18.5%, compared to $52.8 million for the third quarter of fiscal 2013 primarily due to a decline in sales of agricultural protection products as well as a drop in domestic sales of chemicals used in surface coatings. Gross profit increased to $7.5 million, or 5.4%, compared to $7.1 million in the same period last year. This was due to an improved product mix, which resulted in a gross margin of 17.4%, a 400 basis point expansion versus 13.4% in last year’s quarter.

Net sales for the nine month period ended March 31, 2014 were $370.6 million, a 1.6% decrease from the $376.6 million reported for the nine month period ended March 31, 2013. Gross profit was $85.7 million, an increase of 16.2%, compared to gross profit of $73.7 million in the prior year period. Research and development expenses totaled $3.2 million compared to $2.0 million in the prior year period. Operating income totaled $35.2 million compared to $26.0 million in the same period last year, a 35.7% increase. For the nine month period, ACETO reported net income of $23.4 million, or $0.82 per diluted share, compared to $16.9 million, or $0.62 per diluted share, in the prior year nine month period, increases of 38.5% and 32.3% respectively.
