Smith & Nephew 2015 Third Quarter Trading Report

Smith & Nephew delivers 4% underlying revenue growth; maintains full year guidance

29 October 2015

Smith & Nephew plc (LSE:SN, NYSE:SNN) trading report for the third quarter ended 26 September 2015.

Highlights

Commenting on Q3, Olivier Bohuon, Chief Executive Officer of Smith & Nephew, said:

“We are pleased with our progress in 2015, with the third quarter again demonstrating that our actions are delivering a strong performance, such as our above-market revenue growth in Knee Implants and the sustained improvement in Advanced Wound Care. We had a good quarter in the United States, our largest market, and are successfully stabilising our European business which delivered a second consecutive quarter of revenue growth against a market backdrop that remains challenging.”

“Our experience working with Blue Belt Technologies and our customer insight has convinced us that robotics will become mainstream across orthopaedic reconstruction in the foreseeable future. This acquisition is a compelling strategic move, with the combination of complementary products and R&D programmes creating a platform from which we can shape this exciting new area of surgery.”

Third quarter trading update

Our third quarter revenue was $1,105 million (2014: $1,148 million), an increase of 4% on an underlying basis and a decrease of -4% on a reported basis. Foreign exchange was a headwind of -9% and acquisitions added 1% to the reported growth rate.

There were 63 trading days in the quarter, in-line with Q3 2014.

Consolidated revenue analysis for the third quarter

Franchise highlights for the third quarter

Sports Medicine Joint Repair delivered revenue growth of 4%. We produced double-digit growth in Sports Medicine Joint Repair in the US, driven by the benefits of our combined portfolio following the acquisition of ArthroCare. However, overall performance was held back by conditions in China, where we saw a slowdown in capital and consumable sales compounded by de-stocking in our distribution channel. Revenue in Arthroscopic Enabling Technologies was down -2%, with weakness in mechanical resection and capital sales offsetting strong revenue growth from COBLATION^à.

Trauma & Extremities delivered growth of 2%. The EVOS^à MINI Plating System is showing good momentum. In October we launched the TRIGEN^à META-TAN^à System, expanding the clinically proven TRIGEN Nail portfolio with a versatile design that addresses a wide range of femoral fractures.

In the Other Surgical Businesses franchise our Ear, Nose & Throat (‘ENT’) and Gynaecology businesses both performed well, with overall revenue up by 10%. In September we launched the NASASTENT^à Dissolvable Nasal Dressing, a splint used to minimise bleeding and prevent adhesions after sinus surgery.

In Reconstruction, our Knee Implants franchise again delivered strong growth, with global revenue up 6%. The JOURNEY II Total Knee System continues to perform well. Hip Implants revenue was down -2%. Performance would have been flat without the renewed BHR headwind following changes in the indications for use announced this year.

Advanced Wound Care is delivering sustained improvement, with 6% revenue growth in the quarter. This is the third consecutive quarter of above market growth as we realise the benefits of our actions to improve performance in this franchise, including a refocused US sales force.

Revenue in Advanced Wound Devices was up 17%. In addition to a strong quarter of sales from our unique, disposable negative pressure wound therapy (‘NPWT’) device PICO, comparatives from Q3 2014 and subsequent quarters no longer include the impact from the US distribution hold on RENASYS.

Advanced Wound Bioactives growth was 2%, with revenue growth from SANTYL^à being partially offset by the continuing reimbursement headwinds affecting OASIS^à. We anticipate a stronger franchise performance in the fourth quarter and now expect to deliver high single-digit growth for the full year.

Regional performance

We delivered 4% revenue growth in the US for the quarter, reflecting in particular our strong performance in Knee Implants, Sports Medicine Joint Repair and Advanced Wound Care. Growth across our Other Established Markets was 1%. Within this, we continue to successfully stabilise our European business against a market backdrop that remains challenging.

We delivered 8% revenue growth across the Emerging Markets. Growth in most markets remains strong, although China slowed in the quarter, principally affecting Sports Medicine, as mentioned above.

During the quarter we completed the acquisition of the trauma and orthopaedics business of our Russian distributor DeOst LLC, and DC LLC, a Russian mid-tier trauma manufacturing company, significantly boosting our local presence and giving us a manufacturing and distribution platform to take advantage of local market dynamics.

Acquisition of Blue Belt Technologies

Today we announced an agreement to acquire Blue Belt Technologies for $275 million, securing a leading position in the fast-growing area of robotics-assisted orthopaedic surgery.

A separate announcement was issued today giving further details of this acquisition.

Foreign exchange

As previously guided, we expect a significant currency headwind in 2015 on our reported numbers. If current exchange rates prevail to the end of 2015 we would expect a full year translation impact of -8% on reported revenue.

The continued strength of the US dollar against most other currencies, particularly those of the Emerging Markets, and the geographic locations of our manufacturing compared to our sales, is resulting in a significant and unusual transactional currency impact on Smith & Nephew. For 2015, as we have said previously, the headwind to gross margin is largely mitigated by our currency hedging strategy. For 2016, assuming current rates prevail, we expect the adverse impact of the high US dollar to be more material, resulting in an up to 100bps headwind to gross margin. We would expect to partially mitigate this through actions to manage gross margin including COGS efficiencies. We will provide further guidance on 2016 as normal with our Q4 Results in February next year.

2015 outlook

Our guidance for the full year 2015 is maintained. We continue to expect to deliver higher underlying revenue growth in 2015 than in 2014 and an improvement in trading profit margin.

We are pleased with our progress in 2015, with the third quarter again demonstrating that our actions are delivering a strong performance.

Consolidated revenue analysis for nine months to 26 September 2015

5

Underlying revenue growth is used to compare the revenue in a given period to the comparative period on a like-for-like basis. Underlying revenue growth reconciles to reported revenue growth, the most directly comparable financial measure calculated in accordance with IFRS, by making adjustments for the effect of acquisitions and disposals and the impact of movements in exchange rates (currency impact), as described below.

The effect of acquisitions and disposals measures the impact on revenue from newly acquired material business combinations, technologies and recent material business disposals. This is calculated by comparing the current year, constant currency actual revenue (which include acquisitions and exclude disposals from the relevant date of completion) with prior year, constant currency actual revenue, adjusted to include the results of acquisitions and exclude disposals for the commensurate period in the prior year.

Currency impact measures the increase/decrease in revenue resulting from currency movements on non-US Dollar sales and is measured as the difference between: 1) the increase/decrease in current year revenue translated into US Dollars at the current year average rate and the prior year revenue translated at the prior year average rate; and 2) the increase/decrease being measured by translating current and prior year revenue into US Dollars using a constant fixed rate.
