American Well acquires another firm in telehealth industry

American Well, a Boston company that provides technology for doctors to consult with patients via videoconferencing, has acquired another firm in the so-called telehealth industry, Avizia. While American Well focuses on connecting doctors to patients who don’t have access to in-person health care or certain specialties, Avizia focuses on remote communication directly between clinicians. Terms of the deal were not disclosed. Avizia is based in Virginia and reports more than 1,300 hospital deployments, while American Well said its products are used by 75 health systems. The goal of the acquisition is to allow American Well to not only connect health care providers with patients wherever they are, but also to connect local clinicians with specialists to consult about a patient’s specific issues. “You may have a rural hospital that needs a neurologist but doesn’t have one on staff,’’ said American Well chief executive Dr. Roy Schoenberg. “Bringing them together allows us to create a much broader switchboard of live health care services that can be rendered around the country.’’ — MARGEAUX SIPPELL

Marathon Petroleum to buy rival for $23.3b in largest oil refiner deal

Marathon Petroleum Corp. agreed to buy rival Andeavor for $23.3 billion in the biggest-ever deal for an oil refiner that would create the largest independent fuel maker in the United States. The offer, payable in either cash or shares, values Andeavor at about $152.27 a share, the companies said in a statement Monday. That represents a 24 percent premium over Friday’s closing price. Marathon shares sank as much as 8.9 percent in early trading with analysts at RBC Capital Markets seeing the deal done at “peak refining bullishness.’’ Andeavor rose as much as 18 percent. Shares of Andeavor, Marathon, and other independent refiners have soared to record highs this year. Growing fuel demand, both in the United States and Latin America, and a shale boom that’s expanded access to relatively inexpensive domestic supply have given American refiners a leg up against foreign competitors. — BLOOMBERG NEWS

McDonald’s sales rise on fresh patties and new value menu

Higher prices on McDonald’s menu led to surprisingly strong comparable-store sales during the first quarter, sending shares up sharply Monday. The company worked to grow its US business with new initiatives, like swapping out frozen beef patties for fresh ones in its Quarter Pounder burger. It also launched a new value menu earlier this year, reviving its once-popular Dollar Menu, but with items priced at $1, $2 or $3. Sales rose 2.9 percent at established restaurants in the United States, the company’s biggest market. Worldwide, that figure rose 5.5 percent, which is a lot stronger than the 3.6 percent increase that industry analysts had forecast, according to a survey by FactSet. — ASSOCIATED PRESS

Maine company to use grant to focus on growing scallops faster

A Maine firm is set to receive a $300,000 grant to work on a scallop farming technique that has helped the valuable shellfish grow faster in Japan. Coastal Enterprises Inc. will receive the money via The Foundation for Food and Agriculture Research, which is a nonprofit corporation set up by the farm bill in 2014. Coastal will investigate the economic viability of the Japanese technique, which Pingree says has also been shown to grow larger, meatier scallops. The money is part of a round of grants from The Foundation for Food and Agriculture Research that will be matched by five companies, an industry group and three universities. — ASSOCIATED PRESS

Walmart selling British unit to local rival Sainsbury’s for $10.1b

Walmart is selling its British unit, Asda, to local rival Sainsbury’s for 7.3 billion pounds ($10.1 billion), a deal that lets the world’s largest retailer focus on online sales in countries where it has stronger growth prospects and faces less-intense competition. The cash and stock deal will reshape Britain’s supermarket industry. It combines the No. 2 and No. 3 supermarket chains, with a total 31.4 percent share of the market that would put it ahead of the current leader, Tesco, according to data from Kantar Worldpanel. — ASSOCIATED PRESS

Americans increased their spending slightly in March

Americans boosted their spending by 0.4 percent in March, the best showing in three months.

New York Times to expand its television shows and podcasts

The New York Times plans to expand its roster of television shows and podcasts, retooling popular columns and behind-the-scenes tales of its journalism to help attract subscribers who may have never read an article in the newspaper. Buoyed by the success of “The Daily,’’ a hit podcast hosted by Michael Barbaro, Times executives see new storytelling tools as a gateway to audiences who may be coaxed into signing up for the newspaper, executives told advertisers at an event Monday in New York. Projects include a podcast for kids and “Caliphate,’’ an audio series that tells the story of a Times reporter covering the Islamic State. The licensing fees and ads from TV shows and podcasts will be small at first, and unlikely to approach the revenue the company gets from traditional sources. But Times executives see them as tools to attract more subscribers, which now total 3.6 million, including customers for its crossword puzzle and cooking product. — BLOOMBERG NEWS
