Exhibit 99.01

Valero Energy Reports First Quarter 2017 Results

• Reported net income attributable to Valero stockholders of $305 million, or $0.68 per share.

• Invested $641 million of growth and sustaining capital in the first quarter.

• Returned $629 million in cash to stockholders through dividends and stock buybacks.

• Incurred $146 million of costs to meet biofuel blending obligations, primarily from the purchase of Renewable Identification Numbers (RINs).

• Created new VLP segment to report the results of Valero’s majority-owned master limited partnership.

SAN ANTONIO, April 25, 2017 – Valero Energy Corporation (NYSE: VLO, “Valero”) today reported net income attributable to Valero stockholders of $305 million, or $0.68 per share, for the first quarter of 2017 compared to $495 million, or $1.05 per share, for the first quarter of 2016. Excluding adjustments shown in the accompanying earnings release tables, first quarter 2016 adjusted net income attributable to Valero stockholders was $283 million, or $0.60 per share.

“Our team finished another quarter with solid operating results despite a heavy maintenance schedule,” said Joe Gorder, Valero Chairman, President and Chief Executive Officer. “Our focus on safe, reliable operations continues to underpin Valero’s ability to deliver distinctive financial performance even in a soft margin environment.”

Refining

The refining segment reported $647 million of operating income for the first quarter of 2017, compared to $915 million for the first quarter of 2016. First quarter 2017 operating income is in line with first quarter 2016 adjusted operating income of $652 million. The 2016 refining segment results have been retrospectively revised for the effect of reflecting the operating results of Valero Energy Partners LP (NYSE: VLP) as a separate segment consistent with Valero’s current segment presentation, and those revised results have been adjusted to exclude the lower of cost or market inventory valuation adjustment, as shown in the accompanying earnings release tables.

Valero’s refineries achieved 91 percent throughput capacity utilization and averaged 2.8 million barrels per day of throughput volume in the first quarter of 2017, which was in line with the first quarter of 2016.

“Our refining team safely executed turnarounds at the Benicia, Texas City, St. Charles, and Meraux refineries,” Gorder said. “With the bulk of this year’s planned maintenance behind us, our refineries should be well positioned to capture available margin opportunities.”

Biofuel blending costs were $146 million in the first quarter of 2017, which was $15 million lower than the first quarter of 2016, mainly due to lower RINs prices.

Ethanol

The ethanol segment reported $22 million of operating incomefor the first quarter of 2017, compared to $39 million for the first quarter of 2016. Excluding the lower of cost or market inventory valuation adjustment, as shown in the accompanying earnings release tables, adjusted operating income for the first quarter of 2016 was $9 million. The increase in operating income in the first quarter of 2017 compared to the first quarter 2016 adjusted amount was due primarily to stronger ethanol prices. Ethanol production volumes averaged 4 million gallons per day in the first quarter of 2017, which was 301,000 gallons per day higher than the first quarter of 2016. Strong demand for ethanol exports is expected to continue, and domestic ethanol consumption is projected to improve as gasoline season approaches.

VLP

As disclosed in Valero’s 2016 Form 10-K, management created the VLP segment effective January 1, 2017, which reflects the operations of VLP, to align Valero’s segment reporting with the way its chief operating decision maker manages and allocates resources to the business. For the first quarter of 2017, the VLP segment reported $70 million of operating income, compared to $43 million for the first quarter of 2016. The increase in operating income was driven primarily by contributions from the McKee Terminal Services and the Meraux and Three Rivers Terminal Services businesses, which were acquired by VLP from Valero in the second and third quarters of 2016, respectively.

2

Corporate and Other

General and administrative expenses were $190 million in the first quarter of 2017. The effective tax rate of 26 percent in the first quarter of 2017 was lower than expected due to a reduction in the statutory tax rate in Quebec and from the favorable resolution of several state income tax audits.

Investing and Financing Activities

Capital investments totaled $641 million in the first quarter of 2017, of which $245 million was for turnarounds and catalyst.

Valero paid $315 million in dividends and purchased 4.7 million shares of its common stock for $314 million, resulting in total cash returned to stockholders of $629 million in the first quarter of 2017. The company continues to target a total payout ratio of at least 75 percent in 2017. Valero defines total payout ratio as the sum of dividends plus stock buybacks divided by adjusted net income from continuing operations attributable to Valero stockholders.

The company generated $988 million of net cash from operating activities. Included in this amount is a working capital benefit of $151 million for the quarter. Excluding working capital, net cash generated was $837 million.

Liquidity and Financial Position

Valero ended the first quarter of 2017 with $8.5 billion of total debt and $4.5 billion of cash and temporary cash investments. The debt to capital ratio, net of $2.0 billion in cash, was approximately 24 percent.

Strategic Update

Valero remains on track to invest $2.7 billion of total capital this year, consisting of $1.1 billion for growth projects and $1.6 billion for sustaining the business. Included in the company’s growth investments are the Diamond Pipeline, the Diamond Green Diesel capacity expansion, the Houston alkylation unit, and the Wilmington cogeneration plant. Sustaining investments include turnarounds and catalyst in addition to Tier 3 gasoline compliance projects.

“U.S. refined product inventories have declined and are within their five-year ranges,” said Gorder. “Demand for gasoline and distillate remains strong both domestically and internationally. Combined with expectations for continued sweet crude oil production growth and relatively low prices for crude and refined products, consumer demand should be robust this year.”

The company exported a total of 365,000 barrels per day of gasoline and diesel during the first quarter.

Conference Call

Valero’s senior management will hold a conference call at 10 a.m. ET today to discuss this earnings release and to provide an update on operations and strategy.

NOTES TO EARNINGS RELEASE TABLES

(a) During the three months ended March 31, 2016, we recorded a change in our lower of cost or market inventory valuation reserve that was established on December 31, 2015, resulting in a noncash benefit of $293 million ($263 million and $30 million attributable to our refining and ethanol segments, respectively).

(b) Effective January 1, 2017, we revised our reportable segments to align with certain changes in how our chief operating decision maker manages and allocates resources to our business and created a new reportable segment — VLP. The results of VLP, which are those of our majority-owned master limited partnership referred to by the same name, were transferred from the refining segment. Comparable prior period information for our refining segment (as well as that segment’s U.S. Gulf Coast and Mid-Continent regions) and VLP segment has been retrospectively adjusted to reflect our current segment presentation.

(c) We use certain financial measures (as noted below) in the earnings release tables and accompanying earnings release that are not defined under U.S. GAAP and are considered to be non-GAAP measures.

We have defined these non-GAAP measures and believe they are useful to the external users of our financial statements, including industry analysts, investors, lenders, and rating agencies. We believe these measures are useful to assess our ongoing financial performance because, when reconciled to their most comparable U.S. GAAP measures, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and trends. These non-GAAP measures should not be considered as alternatives to their most comparable U.S. GAAP measures nor should they be considered in isolation or as a substitute for an analysis of our results of operations as reported under U.S. GAAP. In addition, these non-GAAP measures may not be comparable to similarly titled measures used by other companies because we may define them differently, which diminishes the utility of these measures.

Non-GAAP measures are as follows:

◦ Adjusted net income attributable to Valero Energy Corporation stockholders is defined as net income attributable to Valero Energy Corporation stockholders excluding the lower of cost or market inventory valuation adjustment and its related income tax effect.

◦ Adjusted earnings per common share – assuming dilution is defined as adjusted net income attributable to Valero Energy Corporation stockholders divided by the number of weighted average shares outstanding in the applicable period, assuming dilution.

◦ Gross margin is defined as operating income excluding the lower of cost or market inventory valuation adjustment, operating expenses, and depreciation and amortization expense.

◦ Adjusted operating income is defined as operating income excluding the lower of cost or market inventory valuation adjustment.

(d) The regions reflected herein contain the following refineries: U.S. Gulf Coast- Corpus Christi East, Corpus Christi West, Houston, Meraux, Port Arthur, St. Charles, Texas City, and Three Rivers Refineries; U.S. Mid-Continent- Ardmore, McKee, and Memphis Refineries; North Atlantic- Pembroke and Quebec City Refineries; and U.S.West Coast- Benicia and Wilmington Refineries.

(e) Primarily includes petrochemicals, gas oils, No. 6 fuel oil, petroleum coke, sulfur, and asphalt.

(f) Throughput margin per barrel represents gross margin (defined in (c) above) for our refining segment or refining regions divided by the respective throughput volumes. Gross margin per gallon of production represents gross margin (defined in (c) above) for our ethanol segment divided by production volumes. Pipeline transportation revenue per barrel and terminaling revenue per barrel represents pipeline transportation revenue and terminaling revenue for our VLP segment divided by pipeline transportation throughput and terminaling throughput volumes, respectively. Throughput and production volumes are calculated by multiplying throughput and production volumes per day (as provided in the accompanying tables) by the number of days in the applicable period.

(g) Adjusted operating income per barrel represents adjusted operating income (defined in (c) above) for our refining segment or refining regions divided by the respective throughput volumes. Adjusted operating income per gallon of production represents adjusted operating income (defined in (c) above) for our ethanol segment divided by production volumes. Throughput and production volumes are calculated by multiplying throughput and production volumes per day (as provided in the accompanying tables) by the number of days in the applicable period.

(h) Average market reference prices for LLS crude oil, along with price differentials between the price of LLS crude oil and other types of crude oils are reflected without adjusting for the impact of the futures pricing for the corresponding delivery

month. Therefore, the prices reported reflect the prompt month pricing only, without an adjustment for futures pricing (known in the industry as the Calendar Month Average (CMA) “roll” adjustment). We previously had provided average market reference prices that included the CMA “roll” adjustment. Accordingly, the average market reference price for LLS crude oil and price differentials for LLS crude oil for the three months ended March 31, 2016 have been adjusted to conform to the current presentation.

(i) Average market reference price differentials to Mars crude oil have been replaced by average market reference price differentials to Argus Sour Crude Index (ASCI) crude oil. Mars crude oil is one of the three grades of sour crude oil used to create ASCI crude oil, and therefore, ASCI crude oil is a more comprehensive price marker for medium sour crude oil. Accordingly, the price differentials for ASCI crude oil for the three months ended March 31, 2016 are included to conform to the current presentation.
