This article has been updated to clarify CFO Ruth Porat’s description of Google’s hardware sales figures after discussions with Alphabet.

Alphabet Inc.-owned Google likely pocketed at least $1 billion from its fourth-quarter hardware sales, but it doesn’t seem possible to pin down a sales number for the company’s big holiday hardware push.

Buried in the company’s financial results largely revolving around the search giant’s $27.23 billion advertising business lies revenue known as Google Other, which banked $4.69 billion in the fourth quarter and is broken into three components: hardware—including smartphone and speaker sales—cloud, and Play Store. Of that Google Other bucket, Alphabet Chief Financial Officer Ruth Porat said on the company’s fourth-quarter call with analysts that Google’s cloud division made $1 billion, which is the first time in years the company has disclosed its revenue.

Porat listed hardware, cloud and Play Store as contributors to revenue in Google Other. On the company’s third-quarter call in response to an analyst question, Porat said that the company ranked those pieces of Google Other in the order which they contributed revenue, from greatest to least.

MarketWatch asked Alphabet whether Porat listed the fourth-quarter contributions in order of magnitude again, and received a response in the affirmative. Based on that, it seemed easy to figure out that hardware revenue was about $2.7 billion—if Cloud made at least $1 billion and Play Store made less, the rest must be attributable to the hardware division.

However, nothing is that easy with Alphabet earnings, which cloak revenue from one of the most important digital properties of all time and require in-depth knowledge of traffic-acquisition costs to truly understand.

On Friday, a Google spokeswoman reached out to MarketWatch and eventually said on the record that Porat listed contributions to Google Other in order of contribution to growth, not revenue, which goes against what Porat said in the third-quarter call with analysts and the earlier email exchange with MarketWatch. Given the opportunity, Alphabet would not deny the accuracy of the $2.7 billion figure outright, nor provide a figure.

For what it’s worth, Jackdaw Research analyst Jan Dawson ballparked about $1.2 billion for fourth-quarter Google hardware sales.

What we can say definitively now is that Google’s new lineup of hardware, announced in October, grew faster than Google’s cloud division and app-store revenue. Among the new gadgets on sale for the holiday quarter that Google launched: its new Pixel 2 smartphones, a virtual-reality accessory for the phones, wireless ear buds, as well as a range of new smart speakers.

The most inexpensive speaker, the Google Home Mini—aggressively marketed and priced at a discount for much of the holiday season at $30—was the easiest way for consumers to access the company’s virtual assistant. Dawson has told MarketWatch that he expects the Home Mini to be Google’s mass-market product.

“It’s one of the only ones that may show up in financial results,” he said.

While the new products aren’t flawless — a bug on the Mini forced the company to make changes — and reviews not always perfect, $2.7 billion in quarterly sales is nothing to sneeze at. But it’s still dwarfed by rival Apple Inc. AAPL, -3.17% and its $61 billion in quarterly iPhone revenue, or 77.3 million units, not to mention its other hardware.

At the moment, analysts polled by FactSet model $4.09 billion in first-quarter sales and $5.83 billion in the 2018 holiday quarter for the Other unit.
