Revlon Inc(NYSE:REV) +2.5% after-hours after announcing that President and CEO Fabian Garcia is stepping down “to pursue other opportunities,” and Executive Vice Chair Paul Meister will oversee operations on an interim basis.

REV also says it expects Q4 revenues of $785M, below $801M from the year-earlier quarter but ahead of analyst consensus estimate of $743M, and a $60M-$80M net loss for the quarter due to a charge related to the recent tax law changes.

REV expects Q4 adjusted EBITDA of $110M-$115M vs. $115M analyst consensus.

CFO Chris Peterson also denies rumors that the company is considering a material asset transfer that would shield assets from lenders.

Rambus Inc.(NASDAQ:RMBS) shares are down 5.5% aftermarket following Q4 results that beat revenue estimates and met on EPS. In-line Q1 guidance (under ASC 605 accounting change) has revenue from $94M to $100M (consensus: $100.38M) and EPS from $0.17 to $0.23 (consensus: $0.18).

Revenue breakdown: Royalties, $77.9M (+10% Y/Y); Product, $8.5M (-27%); Contract and other revenue, $15.5M (+2%); Licensing billings, $76.6M (+18%).Key metrics: Non-GAAP operating margin, 31%; total operating expenses, $67.5M; cash and equivalents, $172.2M; cash flow from operations, $33.3M.

ADTRAN, Inc.(NASDAQ:ADTN) slumped to a 52-week low after forecasting below consensus guidance for Q4, revising its revenue estimate downward  to $125M from $155M-$165M earlier and seeing EPS of ~$0.01; analysts had expected EPS of ~$0.14 and revenue of $161.2M.

ADTN also projects Q1 to come in at roughly the same as Q4, misses analyst consensus of $167.5M.

CEO Tom Stanton says Q4 results have been hurt by a merger-related review, which ADTN expects to be completed in 60-90 days, and slowdown in the spending at a domestic Tier 1 customer.

MKM Partners analyst Michael Genovese believes the customer is CenturyLink (CTL -2%), which accounted for 24% of ADTN’s total sales in 2016.

The analyst thinks the weakness should prove temporary, adding that ADTN’s performance likely will accelerate into 2019 as the company stands to benefit from 5G spending; MKM trims its ADTN target price to $25 from $27 but keeps its Buy rating.
