What happened with Impinj this quarter?

Strong unit growth drove the company's results.

  • Endpoint IC unit volume grew by 70% year over year, totaling 6 billion in 2016.
  • Gross margin increased by 120 basis points year over year to 55.6%.
  • Adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) was $2.4 million, up from $1.5 million during the prior-year period.
  • Impinj raised $107 million in 2016 from equity offerings, including its IPO in July and a secondary offering during the fourth quarter. Total cash and investments were $100.5 million at the end of 2016.

Impinj provided guidance for the first quarter of 2017.

  • Revenue is expected to be in the range of $30.0 million to $31.5 million. This compares with revenue of $22 million during the first quarter of 2016. Revenue is seasonally lower during the first half due to new annual pricing for endpoint ICs.

  • Non-GAAP EPS is expected between a loss $0.06 and a gain of $0.01.

What management had to say

Impinj CEO Chris Diorio summed up both the fourth quarter and 2016:

CFO Evan Fein said during the conference call that the company is on its way to hitting its long-term targets:

Looking forward

Impinj's first-quarter guidance represents year-over-year revenue growth of about 42% at the midpoint, a slowdown compared to the fourth quarter. Seasonality is a factor, according to the company, and it expects this effect will diminish as it continues to grow.

Earnings guidance calling for a non-GAAP loss at the midpoint suggests that costs are going to continue to rise faster than revenue. That was true during the fourth quarter, with operating expenses rising 56.7%, but revenue growth was enough to drive earnings higher.

Impinj is still a small company in the early innings of driving adoption of its radio frequency technology. The company expects endpoint IC volume to reach 7.8 billion to 8 billion units in 2017, a 32% increase compared to 2016.
