Allergan plc AGN is scheduled to report first quarter 2016 results before the opening bell on May 10. The company delivered a positive earnings surprise of 1.19% in the fourth quarter. Let’s see how things are shaping up for the first quarter announcement.Acquisitions to Drive EarningsAllergan’s top as well as bottom line should continue to be driven by the acquisition of Botox-maker Allergan Inc. as well as other acquisitions. However, Namenda IR is facing generic competition.Investors will be interested to hear about Namzaric’s performance. Namzaric was launched in the second quarter of 2015 and is expected to help reduce the impact of the Jul 2015 entry of Namenda IR generics. Namzaric sales should pick up from 2016 reflecting the impact of the DTC campaign launched in September and formulary coverage.Post the termination of the Pfizer, Inc. PFE combination deal, Allergan reiterated its 2016 revenue guidance of about $17 billion including branded net revenues of approximately $15 billion. Revenues will be back-half weighted reflecting typical pharma seasonality. Moreover, contribution from launches are expected to be greater in the second half of the year. On its fourth quarter call, the company had said that it expects first quarter 2016 revenues to be lower sequentially. The first quarter will also be the lowest quarter of the year, with each quarter subsequently increasing.Meanwhile, with the company supporting new product launches this year like Kybella, Viberzi and Vraylar, SG&A as a percentage of revenue will be higher in the first quarter and will trend downwards as the year progresses.The performance of new product launches like Avycaz (treatment for adult patients with complicated intra-abdominal and urinary tract infections) and Viberzi (adults suffering from irritable bowel syndrome with diarrhea) will also be in focus.Meanwhile, Allergan expects to complete the sale of its generics business to Teva Pharmaceutical Industries Ltd. TEVA in June. Allergan is currently treating its generics business as discontinued operations. With after-tax cash and equity proceeds of approximately $36 billion expected from the Teva transaction, Allergan could use the funds to pay down debt or invest in the business or explore other options like share buybacks. On the first quarter call, Allergan intends to provide an update on its plans to simplify company operations post the close of the Teva transaction.Surprise HistoryThe company has had a decent run over the last four quarters with earnings surpassing expectations in three quarters and meeting expectations in the second quarter of 2015.
