Tom Greco
President and Chief Executive Officer at Advance Auto Parts
Thanks, Gene, and good morning, everyone. Before I start, I want to express my sincere appreciation to the Board for all their support over the last seven years. I look forward to working with Gene, Shane and Tony to enable a seamless transition.
As I turn to our Q2 results, I also want to thank all of our team members for their relentless focus on serving our customers. Coming into the quarter, we knew Q2 is going to be challenging and that the investments we're making in both inventory to help improve availability and strategic pricing to maintain competitive price targets would build through the year. On our Q1 earnings call, we talked about moving with urgency with a back-to-basics approach and a heightened focus on execution, and this is how we approach the quarter.
We delivered net sales growth in the quarter, however, the balance of our Q2 financial metrics remain challenged. As Gene noted, while we're executing some operational improvements, there are further actions that need to be taken to accelerate profitable growth. I'll speak to our sales and transactions in the quarter, and Tony will speak to the key drivers behind our results in more detail. Before that, I'd like to touch briefly on steps we've taken recently to better support our people. During the quarter, we made investments to more strongly position Advance in attracting and retaining high-caliber talent in our frontline roles. More specifically, we implemented compensation increases for key roles in our stores and supply chain. In our customer support center, we're also making investments this year to help retain high-caliber talent. We know that having the right compensation in place for our organization is critical to maintaining our strong culture and delivering operational excellence, and we've already seen reduced turnover.
Turning to net sales, we saw growth in both DIY omnichannel and DIFM during Q2, with DIY omnichannel outperforming DIFM through continued e-commerce momentum, which delivered another quarter of double-digit growth. From a category perspective, motor oil, batteries, brakes and engine management led the growth in Q2.
DieHard continues to perform very well and gained unit share within batteries once again in the quarter. Meanwhile, improved availability on our Carquest brand resulted in further own brand penetration in the quarter. Regionally, our sales growth was once again led by the West.
In terms of comparable store sales, the decline of 0.6% was primarily driven by negative comparable-store sales in Pro. However, we saw sequential improvement in each period in both Pro and DIY with the last four weeks of Q2 registering slightly positive comparable store sales growth overall. Our topline sales continue to improve into the third quarter, as we delivered low-single digit comparable sales growth during the first four weeks.
Our performance benefited from the initiatives we've talked about earlier this year to drive improved transactions in both DIY omnichannel and Pro. First, our improved availability was driven by the inventory investments we made along with year-to-date improvements in supply-chain fill rates and store on-hand rates. As in-stocks improved in the quarter, we saw sequential sales growth in key hard parts categories. Second, our category management actions continued in Q2 to ensure we sustain competitive price targets.
In addition, we discussed in the past, the opportunity to increase own brand penetration to improve margins. As discussed on the May call, we launched the sales campaign in Q2. This was primarily targeted at accelerating the transition to Carquest branded products as well as reducing slower-moving inventory in our network.
Finally, our field team is now in full stride, executing a Pro customer activation plan, highlighted by increasing customer sales calls and ensuring a higher level of accountability to grow weekly customer accounts and drive share of wallet gains with existing customers.
Our actions resulted in sequential improvement in transactions in Q2 compared to Q1 in both Pro and DIY. While, DIY omnichannel transactions were down slightly in Q2 versus the prior year, average ticket was up mid single-digits. We continue to make progress, increasing loyalty with DIY consumers as evidenced by ongoing traction with our Speed Perks program which grew by approximately 15%, and ended the quarter with nearly 15 million active members. Our Speed Perks percentage of transactions continues to climb and head over 48% in the quarter, a 420 basis-point increase from this time last year. I'd like to commend our field team for their strong execution of Speed Perks and their dedication to strengthening our value proposition for DIY consumers.
Specific to Pro, we remain committed to delivering a best-in-class customer experience. Transactions move back into positive territory in Q2, an improvement versus Q1. As expected, average ticket was down slightly as we sustained our focus on maintaining competitive price targets and the execution of the targeted sales campaign I just mentioned. Within both strategic accounts and TechNet, we saw improved performance in the quarter, and TechNet grew to almost 17,000 members.
In summary, the actions we've taken to improve availability, sustained competitive pricing and enhance our service helped us drive share of wallet gains and improve our call status with Pro installers, including the very important up-and-down the street business.
With that, I will turn the call over to Tony to review some of the drivers behind our second quarter results and provide an update on our outlook for the full year, Tony?
