Energy Services & Equipment Update

William Blair

Energy Services & Equipment Update

The M&A market for energy services & equipment transactions has been robust in 2014. The year-to-date transaction value of approximately $62 billion represents a 35% increase from the corresponding period in 2013; there have been 331 transactions in the sector thus far this year, which is an increase of 35% over the same period in 2013. The surge in M&A activity is attributable to several factors, including: i) accelerated growth in the energy sector, particularly in North America; ii) increased appetite for energy exposure from buyers; iii) strong access to liquidity; and iv) a continuing economic recovery. The energy sector’s accelerated growth has created what we view as a fundamental change in how buyers are viewing the opportunity to deploy capital in a higher growth and relatively more stable market environment. The favorable energy services & equipment market backdrop has resulted in a larger universe of strategic buyers and private equity funds pursuing energy exposure. For example, several recent, notable deals have been completed in the testing & inspection segment by ALS, Bureau Veritas, Mistras, and TÜV SÜD, who are all looking for increased energy-related revenue. This trend is also accentuated by B/E Aerospace’s leap into the market with five completed energy services transactions since 2013. Additionally, we have seen accelerated activity across generalist private equity funds in the sector such as Norwest Equity Partners’ acquisition of UELS and AAC Capital’s acquisition of Hobré Instruments. These funds have had impressive returns and will look to replicate their success in the highly attractive energy market. The trend of generalist private equity funds pursuing energy exposure has resulted in a record number of financial sponsor transactions, which represent 15% of all energy services & equipment transactions year to date, compared to only 6% in 2010. We expect a continued increase in financial sponsor transactions based on: i) a large number of private equity funds that have aggressively pursued energy services & equipment deals, but have not yet completed a transaction; ii) an increase in the number of funds looking for energy exposure; and iii) a significant amount of capital overhang across private equity funds. Additionally, several strategic buyers have been divesting assets to focus on core operations rather than expanding their service offerings, which bodes well for financial buyers to compete in sale processes. For example, Cameron recently agreed to divest its Centrifugal Compression and Reciprocating Compression business divisions, which were viewed as non-core. Additionally, Weatherford has been shedding non-core assets while selectively pursuing M&A opportunities. While the M&A market has seen strong growth in 2014, valuations have remained in line with historical levels. For the year-to-date period the average EV/LTM revenue multiple is 1.52 times, while the average EV/LTM EBITDA multiple is 8.9 times. Despite a robust M&A market, valuations in the energy services & equipment sector have not ballooned as to stymie deal activity. We believe that current valuations are at a level that will continue to attract strong interest from buyers and will see business owners actively considering or pursuing sale processes. Multiples for publicly traded energy services & equipment companies are above the long-term median levels and are currently trading at 9.0 times EV/LTM EBITDA. Public company valuations have continued to increase from a trough in Q3 2012 of 7.4 times EV/LTM EBITDA, which is largely attributable to improving operating performance and an increasingly favorable growth outlook. Public comparables have collectively lagged the S&P 500 both recently and in the longer term. However, there have been certain segments of the market that have performed extraordinarily well, such as small cap services companies that have materially outperformed the broader market.

Rig Count & Key Economic Data

William Blair

Rig Count & Key Economic Data

Oil & gas activity stands at a near record high with rig counts close to levels experienced prior to the recession in 2008. Year-to-date rig count in the U.S. has increased over 9%. Oil prices remain at attractive levels, which have resulted in a large growth in oil rigs of over 14% in 2014. Gas prices, however, have remained at levels that have not encouraged drilling activity and, as such, gas-related rigs have decreased nearly 9% in 2014. Rig count growth has been skewed to oil rich areas, such as the Permian, Williston, and DJ- Niobrara basins, which collectively have seen over 100 rig additions. We believe that ongoing global conflict will continue to put pressure on oil prices, which will result in continued oil-related drilling activity. We do not foresee a near-term reversal of gas- related activity, but we do have a bullish view in the longer term as capital investment in petrochemicals and natural-gas-fueled infrastructure help to absorb excess gas supply.
