ampm (rarely "am/pm") is aconvenience storechain with branches located in several U.S. states, includingArizona,California,Nevada,Oregon,Washington and in several countries such asCosta Rica andBrazil. The brand pulled out of the Eastern United States in 2012, but returned a decade later.
Theampm brand is owned byBP America, Inc.,[1] a subsidiary ofBP, which acquired its founding owner,Atlantic Richfield Company (ARCO), in 2000. In the United States, the stores are usually attached to an ARCO or BP-brandedgas station. The first location opened in Southern California in 1978.[1]

ampm is owned by a subsidiary ofBP, which acquired its founding owner,Atlantic Richfield Company (ARCO), in 2000. The first ampm location opened in Southern California in 1978.[1] The chain would also have a presence in theNortheastern United States at ARCO locations until ARCO spun those operations off intoAtlantic Petroleum in 1985, with those stores being rebranded asA-Plus. A-Plus remains owned bySunoco (which acquired Atlantic in 1988), though all the company-owned stores were sold to7-Eleven in 2018.
The Japanese chain was originally established by Kyodo Oil Company (laterJapan Energy) in 1989; many of its stores are located within Kyodo Oil (later JOMO)filling stations. It remained under Japan Energy control until it was sold to Reins International Inc, an operator ofKorean-style restaurants in Japan, in 2004.[2] It became a wholly owned subsidiary ofFamilyMart in 2009. Subsequently, am/pm stores were converted into FamilyMart stores.
In spring 2008, U.S. branches of theBP Connect brand of convenience stores rebranded toampm, which also brought the brand under the BP banner after exclusively being under the ARCO banner. The decision saw markets with a large BP presence, such asChicago,Cleveland,Indianapolis,Orlando, andPittsburgh, face rebranding as ampm stores andTV ads.[3] In August 2008, BP announced its decision to sell the majority of its retail operations in theOrlando area toApopka-based Medallion Convenience Stores. Also in 2008, theIndianapolis stores were sold to Ricker Oil, which began operating them under the BP/Ricker's identity; those stores are now owned and operated byGetGo.[4] The Pittsburgh area stores were sold to 7-Eleven; the stores alongside 7-Eleven's later acquisition of ampm spinoff A-Plus supplemented 7-Eleven's legacy locations in the area usually branded withExxon orGulf. TheColumbus, Ohio, locations were sold to locally based Duchess Shoppe in 2010.[5] In November 2009,FamilyMart announced its acquisition of am/pm Japan.[6] Allampm stores in Japan then subsequently rebranded as FamilyMart.[7]

In 2012, inCosta Rica, both ampm and Fresh Market stores were owned by the same company. By the end of that year, there were 38 ampm locations in the country.[8] In August 2012 it was reported that BP had divested, or was planning to divest, all ampm operations East of the Rockies.[9] In 2012, BP announced it would withdraw ampm stores from the eastern US by the end of that year, naming specifically Atlanta, Chicago, Cincinnati, Cleveland, and Orlando. At the time, there were 200 ampm convenience stores in BP fuel outlets in the eastern US, with 900 locations in the western US alongside BP and ARCO outlets. This occurred around the same time that BP divested ARCO itself toTesoro Corporation and licensed the ARCO name from Tesoro for thePacific Northwest andNorthern California while retaining ownership of ampm. As of 2021, BP franchises ampm to independent ARCO owners in theSouthwest United States,[10] though company-owned ampm stores in the area converted toSpeedway followingMarathon Petroleum's purchase of ARCO in 2018.
In 2014, the brand was focusing on food such as "coffee, bakery, fresh sandwiches and hot foods, along with an extensive condiment bar," as well as fountain drinks and refrigerated display cases. It had a value line, "ampm Good Stuff." ampm had 950 stores overall, with headquarters inLa Palma, California, and operations in five states: Arizona, California, Nevada, Oregon, Washington.[11] ampm was nearing its 1,000th location by November 2017.[12] In early 2019, BP had "recently opened its first new-to-industry ampm site" in 12 years, marking the company's 1,000th ampm location in a BP outlet.[13] In May 2019,Ipiranga was operating ampm stores in Brazil, with 2,500 ampm stores at gas stations in the country.[14]
In 2019, BP acquired an ownership stake in rival chainThorntons LLC, and in 2021 announced it would acquire full ownership from partner ArcLight Capital Partners. The deal would make ampm and Thorntons sister chains, though BP plans to keep operations separate. With Thorntons being primarily in theMidwestern United States andFlorida, the two chains do not overlap geographically.[15]
In August 2022, BP opened their first East Coast ampm convenience store in theNew York City borough ofThe Bronx. It also marked the first time the West Coast chain had a presence in the Eastern United States since pulling out in 2012.[16] A secondNew York City location opened inQueens in 2023.
With the division of ARCO between BP andTesoro, West Coast franchising rights were split between BP (Washington, Oregon and Northern California) and Tesoro subsidiary company Treasure Franchise Company LLC (Arizona, Nevada, Utah and Southern California).[citation needed]
Franchised and BP-owned units ofampm are also found in parts ofMexico, usually co-located with aPemex (which is the main provider of gas in the country) and inBrazil usually, with anIpiranga station. InArgentina they could be found inYPF/ACA stations.[citation needed]InChile they formerly operated onPetrobras stations
