CST Brands Inc. (NYSE: CST) began trading on a ‘when-issued’ basis on April 17, 2013. The distribution of 80% of shares by Valero Energy (NYSE: VLO) to shareholders is scheduled for May 1 with regular way trading commencing the following day. VLO reported 1Q 2013 EPS this morning. The retail segment, which comprises the CST spin-off, posted EBITDA growth of about 7% year over year to $72 million as stronger US fuel spreads more than offset weaker Canadian fuel volume. CST has recently traded around $30 per share in the when-issued market, which appears to take into account 5-7% EBITDA growth, while applying a peer group EV/EBITDA multiple (see attached exhibit). However, as noted in the initial Valero Energy Spin-Off Report (January 17, 2013), longer-term investors may consider CST’s ability to improve merchandise gross margins after separation from VLO, which could raise the valuation by about $5 per share.
One may contend that cash flow generated from the retail business was previously funneled into the capital intensive refining operations. CST has generated about $260 million in annual free cash flow (cash flow from operations minus maintenance cap-ex) over the past three years (see page 27 of the initial report). Following the spin-off, CST may be able to utilize more cash inside the stores, increasing prepared food offerings to raise US gross merchandise margins to the peer group average 34% (compared to 29% for CST in recent years, see page 10 of the initial report). In CST’s road show presentation, management highlighted increased prepared food offerings in new stores and internal store redesigns.
Based on a 34% margin, CST would add about $53 million annually to gross profit. Even assuming certain additional marketing and administrative costs, increasing EBITDA or free cash flow by $45 million would seem attainable. Applying the peer group EV/EBITDA multiple of 8.7x, and a 7% free cash flow yield, the valuation would rise $5 per share (see attached exhibit). Based on about a $35 per share fair value, assuming US merchandise gross margin improvement, the stock is recommended for purchase.
