BLACK RIFLE COFFE COMPANY INTRODUCTORY VIDEO

TRANSCRIPT

Evan Hafer, Founder and Co-Chief Executive Officer, Black Rifle Coffee Company

Every adventure starts with a great cup of coffee. All the way back to the birth of America, we’ve been fuelled by coffee. That’s why it’s so special.

I want people to know when they step into the Company that this is owned by the veteran community and I want the veteran community to take pride in that.

There’s a big portion of the American veterans and service members of the United States that they get forgotten. It’s my responsibility as a veteran and as a business member to remind people that they don’t need a handout, they need an opportunity. It’s creating a forced multiplication effect through thousands of veterans that live happy and productive lives so they continue to propagate positive psychological influence to the rest of the veteran community, and inherently, that will translate to the rest of society.

Mat Best, Executive Vice President, Black Rifle Coffee Company

The culture of our company not only from the media aspect but the employees that make it is a lot of us come from Special Operations background, a veteran background, and the caliber of person that works for us, specifically around people that served and fought in wars, is you don’t settle for mediocrity. We always shoot for excellence and that will always be the primary ethos of our company.

Evan Hafer

My goal is to hire 10,000 veterans.

Hiring vets is not PR for me; it’s who we are.

Logan Stark, Editor-in-Chief, Black Rifle Coffee Company

We’re trying to bring these shining examples to the veteran community, and that’s why I love it here.

Evan Hafer

We’re up in Big Sky, Montana, Total Archery Challenge, SOC-F Foundation, Special Forces Foundation, to raise money for adaptive athletes or wounded veterans.

Jonathon Blank, Black Rifle Coffee Customer

Everybody had an awesome time and it gets your outside, which I think a lot of people find therapeutic. So, awesome all round.

The four key growth drivers of the Black Rifle Coffee omnichannel business model are, first, steady growth in our direct-to-consumer business driven by improving the digital experience and new product innovation. Today we have over 270,000 coffee club subscribers.

Second, experiential coffee shops are outposts. This is where the BRCC brand comes to life, offering a daily gathering place to our community where they can come, enjoy premium coffee beverages and a broad selection of merchandise.

Third, ready to drink coffee sold in convenience stores, plus food, drug and mass merc stores. This is a $4 billion category that Black Rifle entered last year. Today we have four SKUs sold in approximately 33,000 doors.

Finally, our wholesale business involves partnering with selected leading national retailers such as Bass Pro Shops. Today, we’re selling coffee and merchandise in roughly 2,200 doors.

In 2019 Black Rifle did about $82 million in revenue. Almost all that revenue came from our direct-to-consumer business which is comprised of our coffee subscription service, as well as other purchases on our website outside of the subscription. In 2020, we were able to double the size of the company with most of that coming from our direct-to-consumer business, but importantly, building some capabilities beyond direct-to-consumer.

Toby Johnson, Chief Operating Officer, Black Rifle Coffee Company

What’s really exciting about the omnichannel presence of our brand is the true incrementality that it brings and these added channels, and as we’ve expanded into new formats we’ve seen that we are reaching our consumer in new ways, in ways that enhance the growth that we’ve achieved in our existing channels. Being digitally native online, opening coffee shops, and then being available in retail has a magnifying effect for the brand and our ability to reach our consumers through multiple channels.

Evan Hafer

I knew that I wanted to join the military early as I could remember. So, right out of high school I joined the Washington National Guard, absolutely I went straight into what was called the Special Forces Qualification Course. I was definitely single-point focused on becoming a Green Beret and pushing myself to intellectual and physical limits. I went to work for the CIA in 2005 and throughout that nine years I spent seven years in combat zones.

Every deployment I went on I was taking small batch roasted coffee with me, modifying our gun trucks in the invasion of Iraq so we could grind coffee and put it through a French press. My team leader and I, we shared a gun truck. Every morning we would cheers through our coffee. It was a special bond over something as insignificant as brown water. Great coffee was one of those things where if you started your day with it, it just kind of made your day that much better.

Evan Hafer

The whole thing was like we’re fuelled by coffee, connected by service. This company is about the customer. The customers are the company. One big ecosystem. We serve coffee to the same kind of people that we are, so they’re one and the same.

Logan Stark

It’s this constant drive to constantly be evolving what we’re doing to give our customers a better coffee experience. Whether that’s a new steep bag, an instant coffee or exclusive coffee that’s from a different type of origin country. The same drive that puts people from basic training into the infantry, into a type of Special Operations capacity, it’s this constant evolution of trying to better yourself and that’s exactly what we’re doing when it comes to coffee, is offering better products on a regular cadence to have a better experience as a customer.

Mat Best

Our true success as a company hasn’t come from throwing wads of cash at third-party marketing agencies. This comes from the values and the ethos of the people that make up this company and I think that’s why our content resonates so much with our audience is we’re a lifestyle brand and we’re living it. We’re not paying someone to define what we do. We live it day in, day out, and no one can take that from us.

We go out and we represent our culture and our country irreverently and as athletically as we can, and I think where other brands are too scared to go, we’re fearless.

Evan Hafer

Lives will be changed. They’ll be changed in a good way.
