EVC: Evidence for a Second Large Smadex Customer

Thesis

EVC’s Q1 2026 10-Q contains credible—but unconfirmed—evidence that a second sizable advertiser became material late in the quarter. If that advertiser is a new Smadex account, the quarter-end balance is consistent with an early ramp that could become meaningful in Q2.

The evidence

• A new concentration appeared. At March 31, EVC’s two largest advertisers represented 24% and 6% of trade receivables. At December 31, no advertiser exceeded 5%.
• The second balance was sizable. Applying 6% to reported net trade receivables of $128.1 million implies approximately $7.7 million outstanding from the second advertiser.
• It was not yet a major quarterly revenue contributor. Only the largest advertiser exceeded 5% of Q1 revenue, placing the second advertiser below approximately $9.85 million of Q1 revenue.
• Timing is suggestive. EVC says invoices are typically due in 30 days. A roughly $7.7 million quarter-end receivable combined with less than $9.85 million of full-quarter revenue is consistent with substantial activity beginning late in Q1.

Why the signal is interesting

The original Hong Kong customer followed a similar pattern. EVC’s Q3 2025 filing explicitly identified a recently acquired large Smadex customer. It initially represented 9% of quarterly revenue and less than 5% of receivables, but by Q1 2026 it represented 36% of consolidated revenue—approximately $70.9 million.That history shows how quickly a newly won Smadex account can scale. If the 6% receivable belongs to another Smadex customer, it could provide an incremental growth engine while beginning to reduce reliance on the Hong Kong whale.

Important limits

• The filing does not identify the second advertiser as new, as a Smadex/ATS customer, or as having started in March.
• Accounts receivable is a point-in-time balance, not a revenue or monthly-spend measure. The $7.7 million figure is therefore not a firm revenue floor.
• EVC also reported $6.9 million due from TelevisaUnivision, close to the 6% concentration amount. The filing does not map the 6% bucket to a named customer, so this is a meaningful alternative explanation.
• Model Edge 2 searches of recent earnings transcripts found only generic comments about more active customers and higher spending per customer. Management did not publicly discuss a second whale or two additional whale-sized accounts.

What would confirm the thesis

The Q2 filing should show the second advertiser’s receivable share persisting or increasing, the advertiser crossing 5% of quarterly revenue, or explicit attribution of ATS growth to another large new Smadex customer.
