An Open Letter to Fellow Ensco Shareholders

 Dear Fellow Shareholders: 

 The opportunity to vote on the proposed Atwood transaction at the October 5 th meeting is quickly approaching. Market and industry events have only deepened our conviction that this deal destroys value for Ensco shareholders – it is the wrong deal at the wrong price and the wrong time.
We urge fellow shareholders to vote AGAINST the transaction directly on Ensco’s proxy card .
Shareholders with questions or needing assistance with voting should contact Morrow Sodali, which is assisting Arrowgrass, at 800-662-5200 or 203-658-9400 or by email at saveensco@morrowsodali.com . We provide access to our materials opposing this deal (which have previously been filed with the Securities and Exchange Commission (“SEC”) and are available on the SEC’s website at www.sec.gov ) at www.saveensco.com . Fellow shareholders should feel empowered to save Ensco from this flawed transaction.

Arrowgrass has opposed the Atwood transaction for the following reasons:

·	Wrong Price: Even based on management’s projections, this transaction is dilutive on all relevant metrics. The proposed Ensco/Atwood stock exchange ratio is at an unjustifiable premium to all-time highs with Ensco stock now at 20-year lows.	
·	Wrong Time: Atwood faces a liquidity wall while burning cash and there is no rush to bail them out at a large premium.	
·	Destroys Optionality: Inappropriately increases risk by shortening runway and weakening the balance sheet, while giving away substantial upside in a recovery.	
·	Wrong Paradigm: Ensco is selling stock on unacceptable terms, not just buying assets.	

Ensco management has taken great pains to argue that they are buying high-quality, desirable assets at an acceptable price, but ignores the question on which we are actually voting: issuing shares. Ensco is selling stock at dramatically discounted levels on an absolute and especially on a relative basis. Not owning Atwood has not held back Ensco from operational wins, including versus Atwood and other competitors in the past months, but the market has punished and will continue to punish Ensco for balance sheet and fiduciary imprudence. This is especially concerning given Ensco’s prior reputation for patience.
As we update our observations and analysis to the eve of the vote, we find further supportive evidence and address incremental considerations and comments by Ensco management.
Ensco shares are down 28% since deal announcement, a clear indictment in and of itself. This, and Ensco’s relative underperformance, has only continued as management defends the deal.

Management argues they have an information edge with an “inside view” that the market does not fully grasp from the “outside in”. Yet, according to their forecasts (on which all of our publicly disclosed analyses are based), this deal is highly dilutive on every metric even in bullish scenarios. Ensco’s own forecasts are the best arguments against this transaction.
Ensco now argues that it knew Atwood would not be able to renew a contract that represented ~50% of consensus EBITDA. News of Atwood losing the contract came only 50 days after the deal was announced and came as a surprise to the market (i.e. it was not priced into Atwood’s share price during the negotiation). Moreover, it was Ensco that won the contract from Atwood, and this win was not priced into Ensco's share price.  Accordingly, the premium Ensco is paying is even greater than shareholders have been led to believe.
The myriad inconsistencies, the flawed arguments and the sheer difficulty management has faced in making the numbers work have made it increasingly clear that something in the process went terribly wrong when this deal moved from concept to execution/timing/negotiation/valuation.
A vote for this transaction is a lose-lose proposition: it burdens Ensco with substantially more operational and balance sheet risk in adverse scenarios while unjustifiably giving away all of the upside, which should accrue to shareholders, in recovery scenarios.  Ensco’s own projections bear this out.
However, voting AGAINST the transaction is a WIN-WIN for Ensco shareholders. This deal would either fall apart or Ensco would be empowered to renegotiate substantially improved terms. If the deal falls apart, Ensco should recover from the sharp underperformance and would be in a stronger position to participate in value accretive consolidation in the future. If the deal is renegotiated at materially better terms, it would also be a win for Ensco shareholders. There is no downside in voting AGAINST this deal.
We urge shareholders not to allow Ensco to sneak this flawed deal through due to shareholder complacency. Please make your views known. Pick up the phone or email your proxy advisor and articulate your thoughts directly to them (more details about how to get involved on www.saveensco.com ).
We may not have the “inside view” but we have something much more powerful in our favor, the benefit of hindsight. This deal has cost shareholders 28%. We should use the safety valve of the vote to save Ensco from making a very expensive mistake.
