On July 13, 2010, Northrop Grumman Corporation (NYSE: NOC) announced that it was exploring strategic alternatives for its Shipbuilding business, including a possible spin-off in a tax-free distribution to shareholders. The new entity would be named Huntington Ingalls Industries Inc. and would trade on the New York Stock Exchange (NYSE) under the symbol ‘HII.’ Northrop’s Board of Directors must still approve the separation. The final capital structure and share distribution have yet to be determined. As no potential buyer of the Shipbuilding business has publicly emerged, NOC is likely to distribute the segment in the first half of 2011. HII has already received preliminary debt ratings from credit rating agencies, and NOC has provided audited stand-alone 2010 financials for the Shipbuilding business, indicating ongoing progress.
Our fair value estimate for Huntington Ingalls (‘HII’) assumes a distribution of one share of HII stock for every share of NOC to shareholders. The net debt assumption for HII of about $1.06 billion is based on historic data presented in the most recent Form 10 filing. Net debt is subject to change prior to the spin. Fitch, in presenting its expected credit rating for HII in late January 2011, noted a likely capital structure that includes about $1.9 billion in debt and around $300 million in cash, resulting in net debt of $1.6 billion. HII will utilize additional debt to make a transfer to its parent and provide initial liquidity, according to the rating agency. Our fair value estimate will be adjusted prior to the spin-off date to reflect the finalized capital structure and share distribution.
NOC is seeking to exit the low-margin, capital-intensive, long-cycle Shipbuilding business to focus greater management energy on the faster-growing, higher-margin remaining business segments, including aerospace and electrical systems. As for HII, the spin-off will enable management to focus on efficiencies and on improving its own underperforming margins. One may arrive at modest upside to the current stock price based on a sum-of-the-parts analysis of the two businesses, but given the current soft environment for defense contractors, including slower to flat spending growth after a decade of rising budgets, closer scrutiny of costs, and the potential for quick termination of underperforming projects, NOC stock is not recommended for purchase ahead of the possible spin-off.
NOC has historically traded below the peer group of leading US defense contractors across most valuation metrics. Following the proposed spin-off of the low-margin Shipbuilding business, the difference between NOC’s operating margin and the higher operating margin for the peer group seems likely to narrow. Northrop management is also focused on reducing exposure to lower-margin work in its other business segments. Therefore, while defense spending growth is likely to slow over the next several years, profit growth may be driven by operating margin improvement. In this environment, one could expect the EV/EBITDA multiple for NOC to approach the higher multiple for the group.
Currently NOC trades at 5.7x forward EBITDA estimates, according to Thomson ONE, compared to a 6.5x multiple for the defense contractor peer group. If one assumes the multiple rises on expected operating margin improvement, post the Shipbuilding spin-off, a 6x multiple for NOC seems reasonable. Applying a 6x multiple to a 2011 EBITDA estimate of $3.58 billion (based on management operating margin and sales guidance and a reasonable split of depreciation and amortization across business lines), one arrives at a price target for NOC post-spin of $73. Given the current stock price, investors seem to apply almost no value to the Shipbuilding spin-off. Alternatively applying an 11.5x multiple to the three-year average (2008-2010) free cash flow for NOC ex-Shipbuilding of $1.83 billion or the mid-range of management’s 2011 free cash flow guidance, which is about $1.85 billion, one still derives about a $73 target. If one expects free cash flow to fall over the next decade as defense spending is reined in, it would be hard to argue paying more than $73 for NOC post-spin.
For the future HII, applying a 5.5x multiple to 2010 audited stand-alone adjusted EBITDA, and assuming a 1:1 share distribution to NOC holders and $1.06 billion in net debt for HII, one arrives at a target of $4 per share. This multiple is in line with Newport News’ trading range post-spin in the mid-1990s during a previous downturn in US Navy shipbuilding. Historical takeover multiples for US shipbuilders have averaged 8x or more, including an 8x multiple for NOC’s takeover of Newport News in 2001 and the recently announced acquisition of Seattle-based shipyard TODD Shipyards (NYSE: TOD). While a takeover seems less likely given previous segment consolidation, an 8x multiple would seem to be the bull case for the stock price. Applying an 8x multiple to trailing EBITDA and utilizing the same assumptions yields a bull case target of $8.
Opting for the more conservative approach and applying the $4 target for the proposed HII and $73 target for NOC post-spin, the sum-of-the-parts analysis results in a $77 target pre-spin for NOC. Given only limited upside and the challenging business environment, the stock is not recommended for purchase. Investors should base their post-spin investment decisions regarding HII and NOC on their fair value estimates of $4 per share and $73 per share, respectively. Those estimates will be reevaluated as more information is made available by the company in amended Form 10 filings.
