By John Licata, founder and chief energy strategist of Blue PhoenixNEW YORK ( TheStreet) -- Stale is a word not typically associated with Exxon Mobil ( XOM), but it's an adjective that I'm afraid represents the company rather well. Exxon's cash position has dropped from more than $38 billion in 2008 to $4.61 billion as of the June 2013 quarter, while the company's debt-to-equity ratio has risen to the highest levels since late 2010 (0.117). So could it make strategic sense for CEO Rex Tillerson to make Exxon more debt heavy near term to position for huge growth longer-term? That strategy has actually helped many major integrated oil companies in the past ( see chart) and it could be the very logic that Exxon must embrace to help pay for stock buybacks and all the recent dividend increases. Exxon's paper, which is rated Aaa by Moody's and AAA by Standard & Poor's, may be more secure than U.S. Treasuries, so the timing could be very appropriate to raise cash, especially as Fed taper talks start to make the rounds again. Also, the company appears to be needing to find new ways to increase earnings and offset a slowing production profile. It also may sting those in the corner offices that Exxon is also no longer the highest market cap company in the world. That distinction goes to Apple ( AAPL). Additionally, there are those in portfolio manager circles who actually prefer investing in Chevron ( CVX) over Exxon Mobil due to that company's increased investments in high-margin oil versus domestic natural gas, which has plagued Exxon with prices still near 40-year lows. Tillerson has been a bit more forthcoming on global warming after being called out for saying civilization will simply adjust to rising sea levels and climate change. Exxon even had a recent keynote presentation at the World Nuclear Association in London. So could Team Tillerson be about to jump into the deep end of the pool and make a splash in the debt market with the intention of raising money for a sizable acquisition ahead of any retirement plans? It's possible. Acquiring BP ( BP) would likely bring a lot of negative criticism to Exxon since there are still bad feelings and outstanding liabilities regarding the 2010 Deepwater Horizon oil spill. ConocoPhillips ( COP) makes sense, but Exxon already has a significant portfolio of natural gas assets. Therefore buying ConocoPhillips would likely face much antitrust scrutiny. The fact that Exxon would have to pay ConocoPhillips a healthy premium and then spend the time to divest the natural gas assets makes me less inclined to think that move would be a match made in heaven. What would get me excited is to see Exxon take a page from French energy company Total ( TOT) and make a large push to capitalize on the growing appetite for solar power. Going solar could help Exxon modernize its energy portfolio and perhaps see alpha not witnessed by shareholders since the company's $40 billion acquisition of XTO.
