I am a senior editor in New York in charge of Bloomberg’s CFO franchise. In that capacity, I manage Bloomberg’s CFO Briefing — a subscriber-only newsletter accompanied by regular TV and radio segments — and run our CFO roundtable series in key financial hubs around the world. We feature top executives at global companies and cover the latest trends in corporate finance.

I previously led Bloomberg’s coverage of U.S. investment-grade bonds and loans, structured finance, ESG and credit markets across Latin America and Canada. Before joining Bloomberg, I served as bureau chief for the Wall Street Journal in New York and worked as a news editor in London. Earlier in my career, I was the U.K. business and finance correspondent for German media group Welt and reported from Shanghai.

Tariff Refunds Leave Companies With Billions to Spend

August 29, 2026

The US Supreme Court’s tariff decision earlier this year left many companies in line for an unexpected influx of cash, and their CFOs with a somewhat unusual question: What to do with the money? More in the latest edition of Bloomberg’s CFO Briefing.

‘Get the Shiniest Thing’ Is No Longer an AI Strategy, McKinsey CFO Says

August 29, 2026

“The biggest change of 2026 when it comes to AI has been that the cost of using it has gone up dramatically. It went from being largely invisible on the [profit and loss statement] to being somewhere between substantial and scary, depending on which type of business you are. We were totally focused on driving adoption and didn’t think about cost at all. We were assuming that costs would go down at about the same speed of the adoption – along the lines of ‘we’re using ten times more tokens, but the price per token will go down by 10 x and therefore it doesn’t matter.’ Turns out we were using a hundred times more tokens and the price hasn’t gone down by 10 x necessarily.”

This and more from McKinsey CFO Yuval Atsmon in the latest edition of Bloomberg’s CFO Briefing.

Free Cash is King as Companies Pour Billions into AI

August 29, 2026

Among the many metrics that companies disclose each earnings season, there’s one in particular that has become key: free cash flow. Investors increasingly scrutinize the amounts of money that companies generate for shareholder returns, debt servicing or dealmaking as they pour billions of dollars into projects such as data centers and computing infrastructure. More in the latest edition of Bloomberg’s CFO Briefing.

CFO Pay Is Rising, but CEOs Are Pulling Away

July 29, 2026

The idea of the strategic CFO comes up in almost every conversation I have with finance executives these days. The role has expanded well beyond accounting and reporting. Many CFOs now oversee functions such as procurement, supply chain and technology, and they’re increasingly seen as the No. 2 or No. 3 candidate to become CEO. But, the increase in relative importance in the corporate hierarchy doesn’t translate into bigger compensation packages in relation to the CEO. The latest edition of Bloomberg’s CFO Briefing looks at what’s driving that disconnect.

CFOs Face a New Question This Earnings Season: What Do Your AI Tokens Cost?

July 29, 2026

It’s earnings season again, and with that come a ton of questions from analysts and investors. As companies report their second-quarter results, CFOs have to prepare for one set of questions in particular: How much do you spend on AI tokens, and is that investment paying off? More in the latest edition of Bloomberg’s CFO Briefing.

AI Boom, Iran Conflict Make IPO Timing a Tough Call

July 15, 2026

SK Hynix’s $26.5 billion listing in New York, the largest ever by a foreign issuer, came just days after the conflict in the Middle East reignited. While the South Korean chip maker went ahead with its transaction, European defense firm KNDS postponed a planned IPO earlier this month after a slump in a rival’s stock put its valuation target out of reach — serving as a reminder of the tough judgment call that companies face in choosing when to go public or sell shares. For the latest edition of Bloomberg’s CFO Briefing, I spoke to finance chiefs and advisors about how to navigate this challenge.
